Description

Slicing device for small diameter cable insulation sheath

technical field

The invention relates to a cable insulation thickness testing system, in particular to a small-diameter cable insulation sheath slicing device.

In addition, when slicing with a blade manually, it is difficult to control the length of the cut insulation sheath of a small-diameter cable. The cut test sample of the insulation sheath will appear too long or too short, making the test image of the sample blurry and unable to Test, as shown in Figure 2. Finally, manual slicing with blades has great safety hazards, and testers are easily cut by the blades during operation.

The lower fixing plate 112 can accurately measure the distance that the one-dimensional adjustment frame 14 moves up or down once, so as to ensure that the multi-section insulation sheath test samples obtained after multiple slices of the small-diameter cable insulation sheath have the same length.

The relevant steps for performing parameter testing on the small-diameter cable insulation sheath by using the small-diameter cable insulation sheath slicing device involved in this application are:

Step 1. Cut off a section of small-diameter cable, pull out the core of the section of small-diameter cable to obtain a section of small-diameter cable insulation sheath, and then apply the insulation sheath to the section of small-diameter cable Sectioning is performed to obtain test samples of multi-section insulation sheaths.

Step 2. Fix the insulating sheath of the small-diameter cable: select the sheath fixing ring 20 with the support hole 21 that is suitable for the outer diameter of the insulating sheath of the small-diameter cable, and place the sheath fixing ring 20 on the second on a mounting plate 12, and tighten the thumb bolts to fix the sheath fixing ring 20 on the first mounting plate 12; the upper end of the small-diameter cable insulation sheath from the support hole 21 of the sheath fixing ring 20 The lower end of the insulating sheath of the small-diameter cable is fixedly clamped in the fixing groove 31 of the cable clamping member 30. Since the support hole 21 and the fixing groove 31 are arranged opposite to each other up and down and coaxially arranged, so The insulating sheath of the small-diameter cable is placed vertically after being fixed, and the support hole 21 has a certain length in the vertical direction, so as to ensure that the insulating sheath of the small-diameter cable will not be skewed.

Step 3, press the power switch 110 on the casing 80, turn on the power, rotate the speed control knob 120, adjust the rotation speed of the motor 50 to an appropriate speed, then the motor 50 drives the three-jaw chuck to rotate synchronously, and the three-jaw chuck The disk drives the insulating sheath of the small-diameter cable to rotate synchronously; due to the limitation of the sheath fixing ring 20, the insulating sheath of the small-diameter cable will rotate vertically to ensure that the cut end surface is even and even.

Step 4. Push the blade holder 40 forward, and the blade holder 40 drives the blade to move forward synchronously to cut the insulating sheath of small-diameter cables in rotation; since the angle α between the blade and the horizontal plane is 10°, the The small-diameter cable insulation sheath is cut by a small-angle blade, and the cutting end surface is close to the horizontal due to the inclination angle of the blade, so there will be no burrs on the cutting end surface, and the cutting end surface is perpendicular to the small-diameter cable insulation sheath, not There will be a larger inclination angle; so far, the upper end face of the insulating sheath of the small-diameter cable has been cut out, and the upper end face is also the upper end face of the insulating sheath test sample.

Step 5, press the power switch 110, the motor 50 stops rotating, and the blade holder 40 is moved backward and reset, so that the value on the digital display screen of the digital display vernier caliper 70 is cleared; turn the handle 62 to make the one-dimensional adjustment frame 14 Move down, according to the value on the digital display screen of the digital display vernier caliper 70, the downward distance of the one-dimensional adjustment frame 14 can be intuitively judged, and this value is: the downward distance between the sheath fixing ring 20 and the blade, and the insulating sheath to be intercepted Test the length of the sample; after the one-dimensional adjustment frame 14 drives the sheath fixing ring 20 and the blade to move down for a suitable distance, repeat step 4 to cut the insulation sheath test sample from the insulation sheath of the small-diameter cable. Therefore, by digital display vernier caliper 70 can guarantee that the length of each section of insulating sheath test sample after cutting is consistent, and meets the requirement of testing instrument; Vertical, high flatness, very small deformation, no burrs, as shown in Figure 6.

Slicing is simple, convenient and quick to operate. After cutting, the cut end face is flat, and the length of each section of the insulation sheath test sample cut is uniform, and the loss of the insulation sheath of the small-diameter cable is small, so that human factors will affect the subsequent small-diameter wires. The test influence of cable insulation sheath parameters is controlled to the minimum. In particular, compared to the cutting method in the prior art where the cable does not move and the blade rotates and translates, this application uses a small-diameter cable insulation sheath to be clamped by a three-jaw chuck, and the motor 50 rotates to make the small-diameter wire The cable insulation sheath rotates in the sheath fixing ring 20. Since the application cooperates with a plurality of sheath fixing rings 20, it is ensured that the diameter of the support hole 21 can be cut in conjunction with the outer diameter of the small-diameter cable insulation sheath; When the direction of the wire diameter cable insulation sheath pushes the blade holder 40, the blade cuts the rotating small wire diameter cable insulation sheath; since the sheath fixing ring 20 is used to support the small wire diameter cable insulation sheath, the small wire The cable insulating sheath is perpendicular to the cutting end face, so the cut plane is smooth, and the upper and lower end faces of the insulating sheath test sample have a high parallelism, which will not flatten the insulating sheath of small-diameter cables. This application is especially suitable for cutting diameter comparisons Insulation sheath for small wire diameter cables, the minimum diameter can reach 0.5mm.

Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial application value.

The above-mentioned embodiments only illustrate the principles and effects of the present invention, but are not intended to limit the present invention. Anyone skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical ideas disclosed in the present invention should still be covered by the claims of the present invention.
