In the swing actuators of the existing disclosed pneumatic angular stroke, one of them is to convert the straight motion of the cylinder or film air bag into an angular stroke through the rack and pinion mechanism or the pin shaft mechanism, so the result is complicated; The intensity of the stress presents a high-level transmission from small to large, and the rack gear or pin shaft, which is the highest stress-bearing part, becomes the weak link that affects the life; The use space of non-executive power action is reduced, and the compressed air is wasted in action switching; due to the high processing precision of parts and different shapes, the manufacturing cost is relatively large; the volume of parts is also large; due to the large stress Many parts are basically made of metal materials, and the weight of the swing actuator is also relatively large, while the anti-corrosion performance of metal materials is significantly lower than that of organic composite materials.

There are centrifugal pumps, plunger pumps and piston compressors in the existing disclosed pressure-feeding fluid machines. The stress intensity occurring in the dynamic process presents a high-level transmission from small to large. As the highest stress-bearing parts, cranks, connecting rods, and pins become weak links that affect life. Due to the need to meet the strength requirements of large peak stress , Many parts are basically made of metal materials, and the anti-corrosion performance of metal materials is significantly lower than that of organic composite materials; these mechanical parts have many types, complex structures, high costs, and low mechanical work efficiency. In the existing public information, we have not found any information about the piston swing drive machine for the clamp swing tray.

In the description of this article, the orientation terms such as plumb line, horizontal line, plumb normal plane, horizontal normal plane, up and down, left-handed, right-handed, and front and back all refer to the concept of a relative system. In the description, the rotation center line of the swing actuator is temporarily in the plumb state; if the rotation center line of the swing actuator is changed to a horizontal state, then the above-mentioned plumb line, horizontal line, plumb normal surface, horizontal normal surface, front The meaning of the relative earth orientation and the latter will also change, but in each system, the interrelationship of each component remains unchanged, which has no effect on the specificity of the described technical characteristics. In this way, the swing actuator can not only be used with the center line of rotation of the tray in a plumb state in space, but also can be used in a state where the center line of rotation is in a horizontal state or in a state where the center line of rotation is at an arbitrary angle in space.

Obviously, the fixation and swing of "fixed tray" and "swing tray" are relative concepts. One of the trays can be fixed and the other can be swung. The interface of the outer connecting pipe of the inlet fluid passage and the outlet fluid passage can be arranged on the axial end surface of the outer contour of the tray, or on the radial circumferential surface of the outer contour of the tray. If the so-called "swing tray" is fixed, " The fluid inlet channel and the fluid outlet channel set on the "fixed tray" will swing accordingly, which will affect the stability of the pipeline, and the compressed air or pressure liquid pipeline is easy to be damaged and leaked. The shaft hole and shaft rod of the inner axial connection mechanism can exchange positions on the fixed pallet and the swing pallet, and the shaft rod of the inner axial connection mechanism is arranged on the swing pallet, and the structure is slightly simpler.

It is recommended that the inlet of the exhaust fluid channel of each working chamber be set on the adjacent stationary piston sheet on the left-handed end face of the rocking piston sheet or on the adjacent stationary piston sheet on the right-handed end face. It is also possible to place each working chamber The inlet of the exhaust fluid passage is arranged on the chamber wall of the left-handed end surface of the rocking piston plate close to the adjacent stationary piston plate or on the chamber wall of the right-handed end surface close to the adjacent stationary piston plate. Since the working chamber on the swinging tray is in a changing state during the swing, it is not easy to observe directly, and the calculated value can only be seen after measurement. Therefore, the working chamber in this article refers to the working chamber on the fixed tray.

In principle, there is no limit to the number of pistons set on the tray. The larger the diameter of the tray, more can be set, but the stationary pistons should be matched with the swinging pistons, and each The swinging piston plate needs to be equipped with at least one stationary piston plate; if 3 piston cylinders and piston groups are formed in the actuator, the output torque of the swinging tray is three times that of a swinging piston plate. The swinging piston plate swings between the left and right helical directions in the piston cylinder formed by the fixed tray, the swinging tray and the stationary piston plate. For the drive machine that is only provided with a piston-cylinder-piston group, the maximum angular stroke of the rocking piston plate rotating around the center of the tray is 360° minus the angle occupied by the stationary and rocking piston plates.

The operation steps of the piston swing driving machine for clamp swing tray use the fluid pressure to send the piston to drive the load to perform angular stroke swing operation: 1. The high-pressure fluid driven is liquid or gas. The high-pressure fluid enters the working chamber through the multi-position reversing valve and the fluid inlet channel on the left-handed end face side of the rocking piston slices of all pistons, cylinders, and piston groups. The fluid residing in the working chamber part on the right-handed end face side of the slice is discharged to the outside world or the atmosphere through the exhaust fluid passage of the working chamber on the right-handed end face side of the rocking piston slice, and the swinging tray drives the drive of the swinging torque output through the power in and out bonding structure The shaft completes the task of angular stroke rotation, and the drive shaft for swing torque output can be the valve stem that drives the opening and closing of the valve plate of the valve. The multi-position reversing valve can exchange the roles of the "inlet fluid passage" and "discharge fluid passage" of the piston cylinder piston group. It can also follow the above principle to make the swinging piston plate drive the load not only to the right but also to the right direction. left-handed swing requirement. 2. The operation steps of the one-way rotation working mode of the piston swing driving machine with a one-way clutch are as follows: the swing piston plate of this layer drives the swing tray to be dynamically coupled with the input shaft of the load through the one-way clutch, and the high-pressure fluid It enters the working chamber on the left side of the rocking piston through the multi-position reversing valve, and the pressure makes the rocking piston rotate to the limit position, and the rocking piston drives the rocking tray and the driving shaft of the rocking torque output to work. When the swinging tray and the swinging piston piece produce the reverse action of the compressed fluid after the reversing control valve is reversed, the drive shaft of the swinging torque output will slip between the swinging tray, and the output shaft will be under the action of the inertia generated by the load or other driving forces Continue to keep rotating in the original direction. When the swinging piston piece is reset to the limit position, the reversing control valve changes direction again, and the swinging piston piece of the driver drives the swinging tray and the input shaft of the load to continue the unidirectional rotation. Although the working chamber The oscillating piston inside swings back and forth, but the input shaft of the load always rotates in one direction, thus driving the load equipment to complete the task. Its forced lubrication system can use a small amount of lubricating oil spray carried in the supplied high-pressure fluid to forcibly lubricate the sliding friction and rolling friction parts.

The operation steps are as follows: the motor drives the drive shaft to swing through the crank rocker mechanism, and the drive shaft drives the swing through the in and out bonded structure. The tray rotates to the left to carry out the suction of the load. At this time, the fluid enters the working chamber space on the left-handed end face side of the rocking piston plate from the one-way valve in the fluid inlet channel, and the fluid in the working chamber on the back pressure side of the rocking piston plate flows from the inlet and discharge fluid channel. Exhaust to the atmosphere, swing the piston piece to the limit position and change direction; when the pressure range of the load is high, the fluid inhaled just now is discharged from the working chamber through the one-way valve of the discharge fluid passage, and the fluid in the atmosphere enters the swing piston from the intake and discharge fluid passage in the working chamber on the back pressure side of the sheet. The one-way valve in the fluid inlet and outlet channel system can be a combination of one-way valves respectively arranged on the stationary and swinging piston plates, or a combination of one-way valves on the swinging piston plate and one-way valves on the fixed tray.

The driving machine mechanically drives the double-acting piston to pump the fluid load. The operation steps of the pumping work are: the operation steps of the double-acting pressure-feeding and single-acting pressure-feeding are basically the same, the difference is that the two ends of each independent working chamber Each is provided with a set of fluid inlet passages and outlet fluid passages for feeding and discharging pressure-feeding fluids. The fluid inlet passages of each channel are connected to a one-way valve that can only enter fluid, and the fluid outlet channels of each channel are connected to a one-way valve that can only discharge fluid. valve. The oscillating piston in the actuator sucks in fluid or presses out fluid from the two one-way valves at the end of the working chamber in the left and right rotation directions, and the fluid that each oscillating piston is pressed turns from the adjacent left or right The one-way valve of the turning stationary piston plate is pressed out, and the drive shaft drives the swinging tray to rotate left and right through the power-in and out-bonding structure to carry out the suction and pressure strokes of the load, and the swinging piston plate performs work in the left and right swings.
