Detailed ways

The specific implementation of the utility model will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. As shown in Figure 1-4, a new cable terminal ring slitting device is characterized in that it includes a ring cutting mechanism 100 for rotating and cutting the cable, a slitting and cutting mechanism 200 for slitting the middle position of the upper end of the cable and A support plate support mechanism 300 for supporting and fixing cables;

As shown in Figure 1,

Wherein the circumcision cutting mechanism is mainly composed of four main parts: circumcision spiral micrometer 110 , tool holder 120 , circumcision bracelet 130 , handle 140 , and bearing device 150 . As shown in accompanying drawing 3, wherein handle is fixed on the circumcision bracelet, is convenient to the rotation of circumcision bracelet. The support of the knife rest is fixed on the circumcision bracelet with bolts, and the support of the knife rest bears the circumcision spiral micrometer, and the inherent knife rest under the knife circumcision spiral micrometer. The circumcision bracelet is inserted into the inner ring of the bearing. When the handle is turned, the knife holder device rotates with the bearing to drive the circumcision bracelet, and at the same time, it achieves the purpose of circularly cutting the cable sheath. The outer ring of the bearing is fixed on the flat plate in the support structure of the support plate and the support plate on the ground, and they are fixed with bolts.

Wherein said slitting and cutting mechanism is mainly composed of: slitting spiral micrometer 210, tool holder main plate 220, slide rail slider structure 230, tool device 240, gasket 250 on the slider, and push handle 260. As shown in Figure 5. The slitting spiral micrometer is connected to the main plate of the tool holder, the front end of the main plate of the tool holder is connected with the tool device for longitudinal cutting, and the lower part of the main board of the tool holder is connected with the slider of the slide rail slider structure. When the slider moves back and forth on the slide rail, it drives the cutter device to cut longitudinally. The slide rail is fixed on the flat plate, and the cutter device is facing the middle of the whole device, which ensures that the cutting position is at the central axis of the cable during longitudinal cutting.

Wherein the support plate support mechanism is mainly composed of five parts: a flat plate 310 , an underframe 320 , a horizontal frame 330 , a support plate 340 , and a ground support plate 350 . As shown in Figure 6, the supporting structure of the support plate adopts a symmetrical method to center the cables, and rail grooves and small holes are opened on the support plate on the ground for positioning and limiting of the chassis. The support plate is used to support the ground support plate and the flat plate, and is used for connection and support. The horizontal frame is mainly to connect and fix the three base frames together, which is convenient for the connection of the device and the positioning of different cable lengths. Bolts 351 are used to block the bottom frame on the right side of the ground support plate for lateral positioning, and the cable does not slip when the cutter structure is slitting. The flat plate is connected with the slide rail in the longitudinal cutting structure, and the flat plate and the ground support plate are connected with the bearing cartridge by the sticky plate.

The original intention of this design is to cut the cable sheath conveniently and clamp it in the fastest time, so the ring cutting adopts the bearing structure, and the bottom frame is used for clamping when cutting longitudinally, and the sliding block slide rail structure is used for pushing. Can save time and effort and convenient and effective mining. The cutter support is fixed in the handle device when cutting in the circumferential direction, so that the circumcision can be ensured when the knife rotates along the circumcision bracelet. When cutting longitudinally, the tool holder is fixed on the main body plate of the tool holder to ensure that the knife moves on the slide rail along the slide block.

For some cables that are not completely straight, a number of different positions are used to set the chassis at intervals, and the cables are cut as straight as possible, avoiding the situation that the cables are not straight under certain circumstances and the cutting depth is inconsistent occur.

Cutter device mainly is by: handle 241 on the knife rest, cover 242 on the knife rest, cutter part 243, knife rest cover 244, screw knob 243/246, blade 247 forms. As shown in accompanying drawing 7: open the adjusting knob, so that the cutter is in a movable state as a whole. When the blade is in contact with the cable, the locking knob 246 is locked, and this step completes the zeroing of the cutter.

Adjust the top knob of the screw micrometer. When the cutter head is in contact with the surface of the cable, this step is the zero adjustment of the cutter head. Rotate the screw micrometer to adjust the feed of the cutter head, so that the cutting work can be carried out.

The innovative point is that the feed rate of the tool can be adjusted with a micrometer, which can precisely adjust the tool, and other tools cannot be adjusted so accurately.

Combining circumcision and slitting into one, it can save time and effectively perform circumcision and slitting at the same time.

Using the bearing to rotate for circular cutting and using the slide rail for longitudinal cutting can save labor and cut efficiently.

A certain arc is programmed on the bottom frame, which can reasonably locate the cables; it is very convenient to fix, disassemble and locate the bottom frame by clamping the bottom frame with bolts.

In this device, firstly, the cable 400 is fixed with the base frame and the bearing, then the circumferential cutting is performed, and finally the base frame is loosened to further push the cable into the supporting structure of the support plate, and then longitudinal cutting is performed.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the scope of protection of the present utility model.
