Detailed ways

The utility model will be further described in detail below in conjunction with the embodiments and accompanying drawings, but the implementation of the utility model is not limited thereto.

Example 1:

A wire pulling device of a wire stripping machine as shown in Figure 1 includes an operating table 1 of the wire stripping machine and a wire pulling device located on the operating table 1. There are at least two wire pulling devices, and the wire pulling device includes a drive The device 2, the connection block 3 connected to the driving device 2, the pull block 4, the connecting rod 5 movably connected to the pull block 4 and the connection block 3, the pull block 4 of the pull wire device is placed overlappingly and on the pull block 4 A connected wire hole 6 is provided, and a conduit 7 is arranged on the operating table 1, and the wire conduit 7 is located directly below the wire hole 6, and a guide groove 8 is arranged on the operating table 1, and the The connection block 3 is located in the guide groove 8.

In this embodiment, the cables pass through the wire holes 6 sequentially from the conduits 7, and after one end of the cables is cut, the cable pulling device can be controlled to pull the cables to separate the cut cable sheath from the cables. The driving device drives the movement of the connecting block, the cable is located in the wire hole 6, and the movement of the connecting block drives the connecting rod 5 to move. At this time, the connecting rod 5 not only has a force perpendicular to the wire hole 6 on the pulling block 4 , there is also an active force parallel to the wire hole 6, and the active force parallel to the wire hole 6 pulls the cable from different directions, that is, multiple pulling blocks 4 are needed to clamp the cable, that is, at least two pulling devices are needed. The active force perpendicular to the wire hole 6 drives the cable wire to move to one end of the conduit 7, so that the cut cable sheath can be separated from the cable. After the cut cable sheath and the cable are completely separated, the driving device controls the connecting block 3 to move in the opposite direction, and the wire hole 6 of the pulling block 4 loses the clamping effect on the cable, and the stripped cable can be removed.

Example 2:

As shown in Figure 1, a wire pulling device of a wire stripping machine, on the basis of Embodiment 1, the present embodiment discloses the driving device, that is, the driving device 2 is a hydraulic cylinder, and the connecting block 3 is fixed The piston rod in the hydraulic cylinder is connected. The driving device controls the connecting block 3 to move in a straight line, and the hydraulic cylinder is used to realize this function, which has a simple structure and is easy to control.

Example 3:

As shown in Fig. 1, a wire pulling device of a wire stripping machine, in order to simplify the structure, this embodiment adopts two wire pulling devices on the basis of the above embodiment.

Said includes a left pulling device and a right pulling device, and the guide grooves 8 of the left pulling device and the right pulling device are located on the same straight line.

Using multiple wire pulling devices can realize the clamping effect on the cable during the pulling process. However, too many wire pulling devices require multiple driving devices and other structures, which makes the structure more complicated and the cost higher. The use of two pull wire devices achieves this purpose and also saves costs. The cables are clamped respectively from both ends of the diameter of the cables, and the clamping effect is good. When the left pulling device and the right pulling device pull the cables, the force of the connecting rod 5 acting on the pulling block 4 acts The force is decomposed into the force perpendicular to the direction of the cable and the force parallel to the cable. The force of the left pulling device and the right pulling device is decomposed into the force perpendicular to the direction of the cable to cancel each other, that is, the direction of the cable is perpendicular to the cable. The wire has no pulling force, only the active force parallel to the cable wire is left to pull it, so when two wire pulling devices are used, the guide grooves of the two wire pulling devices are located on a straight line.

Example 4:

As shown in Figure 1, a wire pulling device of a wire stripping machine, in order to facilitate the insertion of the cable, this embodiment, on the basis of the above embodiment, makes the wire hole 6 on the pulling block 4 closest to the wire conduit 7 The opening is trumpet-shaped. The trumpet shape has a large opening, which is convenient for cables to be inserted into the wire holes 6 .

As mentioned above, the utility model can be better realized. the
