Description

Automatic clam blade grinding machine

Technical Field

The invention relates to the technical field of tool processing, and in particular to an automatic clam blade grinding machine.

Background Art

Clam blade is a type of knife sharpening method. The side profile curve bulges outward, resembling a clam, hence the name. It is also called clam blade or convex grind. During the cutting and chopping process, the contact surface between the blade surface and the object being cut is smaller than that of other blade edges, and the resistance is small, so the retention and cutting performance are better, and cutting is more labor-saving. Traditional Chinese kitchen knives are generally clam blades, while modern knives are mostly V-blades (flat blades). The disadvantage of V-blades (flat blades) is that they are less durable and are more likely to collapse when cutting hard objects.

At present, the clam blades of domestic knives are basically polished by hand. There is currently no machine or equipment that can automatically process clam blades. Manual polishing requires the operator to have high grinding skills. In addition, manual polishing has poor consistency, low efficiency, and high labor costs. Therefore, it has also affected the development of clam blade tools to a certain extent.

Summary of the invention

In view of the existing technical problems, the present invention provides an automatic clam blade grinding machine to solve a series of problems caused by manual grinding of clam blades in the prior art.

By adopting the above technical scheme, when in use, the rotation of the rotating shaft drives the flap wheel and the cloth wheel to rotate, and the outer diameter detection mechanism first detects the outer diameter of the flap wheel to ensure that its outer diameter is within a reasonable range. At the same time, the automatic wheel repairing and waxing mechanism repairs and waxes the cloth wheel. After the above steps are qualified, the clamping claw is driven by the manipulator, and the clamping claw clamps the tool to first sharpen the blade on the flap wheel, and then deburr and grind on the cloth wheel. During the deburring process, there must be solid wax on the cloth wheel so that the cross-sectional shape of the opened clam blade is good.

A curved seat 41 is slidably arranged on the second servo module 40. A slide rail 410 is arranged on the curved seat 41 in the vertical direction. A slider that can move along the slide rail 410 is arranged on the mounting seat 42. The mounting seat 42 is driven to rise and fall by a lifting cylinder 411, and the lifting cylinder 411 is installed on the curved seat 41. The mounting seat 42 is in an L-shaped structure, and the vertical surface of the L-shaped structure is connected to the slide rail 410 through a slider. A cutter seat 43 is arranged on the horizontal surface of the mounting seat 42, and a cutter 430 is installed on the cutter seat 43, and the cutter 430 is directly opposite the cloth wheel 72. A wax block box 44 is arranged on the mounting seat 42 at a position directly above the cutter 430. A wax block 440 is placed in the wax block box 44, and the positions of the wax block 440 and the cutter 430 and the cloth wheel 72 correspond. An electric push rod 48 for pushing the wax block 440 forward is also arranged on the rear side of the mounting seat 42, and the electric push rod 48 is connected to a push rod seat 480, and the push rod seat 480 is arranged on the bent seat 41. A fixed block 481 is also arranged on the push rod seat 480, and the electric push rod 48 passes through the fixed block 481, so as to prevent the free end of the electric push rod 48 from shaking randomly during use. A groove 412 is formed on the vertical plate of the curved seat 41 , and the groove 412 opens upward, through which the electric push rod 48 passes, so that when the mounting seat 42 moves up and down, the electric push rod 48 can always correspond to the position of the wax block 440 .

A set of clamping mechanisms for pressing the wax block 440 are respectively arranged at the positions on both sides of the wax block box 44 on the mounting seat 42. The clamping mechanism includes a clamping cylinder 45 fixed on the horizontal plane of the mounting seat 42 in the vertical direction, and a wax block pressing plate 46 is hinged at the movable end of the clamping cylinder 45.

The outer diameter detection mechanism first detects the outer diameter of the flap wheel 71 to ensure that its outer diameter is within a reasonable range. The specific detection process is that the first servo module 60 drives the Y-shaped connecting plate 61 and the detection sensor 62 to move forward. When the detection sensor 62 detects the signal of the flap wheel 71, the first servo module 60 stops moving. Since the initial distance between the first servo module 60 and the flap wheel 71 is certain, the diameter of the flap wheel 71 can be calculated according to the moving position of the first servo module 60, and then it is determined whether the flap wheel diameter meets the requirements. At the same time, the automatic wheel repairing and waxing mechanism 4 repairs and waxes the cloth wheel 72.
