[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] See also Figure 1 —5. A tool for chamfering the center conductor of a cable, comprising a fixing seat 1, and also comprising a driving unit 2, a positioning seat 3 and a chamferer 4 arranged on the fixing seat 1. One end of the chamferer 4 is connected to the output end of the driving unit 2, and the other end of the chamferer 4 is rotatably connected to the positioning seat 3. One end of the chamferer 4 is provided with a first groove body 41 and a second groove body 42. The first groove body 41 and the second groove body 42 are arranged alternately, and the first groove body 41 and the second groove body 42 are communicated with each other. A chamfering edge 43 is formed at the intersection of the first groove body 41 and the second groove body 42, and the chamferer 4 is driven to keep rotating by the driving unit 2.

[0025] A driving unit 2 and a positioning seat 3 are fixedly installed on the outer wall of one side of the fixing seat 1. Preferably, the output end of the driving unit 2 is horizontally placed, and the central axis of the driving unit 2 is in the same plane as the central axis of the positioning seat 3, so that the output end of the driving unit 2 and the central axis of the positioning seat 3 can be in the same plane to ensure the uniformity of the rotation of the chamferer 4. Specifically, one end of the chamferer 4 is connected to the output end of the driving unit 2, and the other end of the chamferer 4 is rotatably connected to the positioning seat 3. A first groove body 41 and a second groove body 42 are provided on the end face of the chamferer 4 away from the end of the driving unit 2. The first groove body 41 and the second groove body 42 are staggered, and the first groove body 41 is connected to the second groove body 42. Since the first groove body 41 and the second groove body 42 are staggered, a groove as shown below will be formed at the intersection of the first groove body 41 and the second groove body 42. Figure 3 The four chamfering edges 43 shown are used to drive the chamferer 4 to rotate continuously through the output end of the driving unit 2. During the rotation of the chamferer 4, the chamfering edges 43 rotate along with the chamferer 4. When the center conductor is inserted into the chamferer 4, the end edge of the center conductor is chamfered by the chamfering edges 43 that rotate along with the chamferer 4. Figure 1 As shown, a protective cover is provided on the fixing seat 1, and the driving unit 2 is provided inside the protective cover.

[0026] As an embodiment provided by the present invention, the driving unit 2 is specifically a driving motor.

During the rotation of the chamferer 4, the first slot body 41 and the second slot body 42 keep rotating synchronously. The chamfering edge 43 formed at the intersection of the first slot body 41 and the second slot body 42 keeps chamfering one end of the center conductor, which can ensure the uniformity of the chamfer of the center conductor, replaces manual chamfering by rubbing, reduces labor intensity, and improves the efficiency of chamfering the center conductor.

[0028] As a further embodiment provided by the present invention, the chamfering device 4 includes a plurality of chamfering blocks 44 and a fixing sleeve 45, such as Figure 4 and Figure 5As shown, the chamfer block 44 is a fan-shaped column structure as a whole. The first groove body 41 and the second groove body 42 are respectively opened on the adjacent two sides of the top of the chamfer block 44. The intersection of the first groove body 41 and the second groove body 42 forms a chamfered edge 43. A plurality of positioning holes are opened on the outer wall of the fixed sleeve 45. The positioning holes can be connected to the inside of the fixed sleeve 45 by connecting screws. As an embodiment provided by the utility model, the number of chamfer blocks 44 is four, and the number of positioning holes is adapted to the number of chamfer blocks 44, so that the multiple chamfer blocks 44 can be accurately positioned and fixed. At the same time, the design of multiple chamfer blocks 44 allows the replacement of a separate chamfer block 44 after a certain chamfer block 44 is worn, which can reduce the overall production cost. One end of the fixed sleeve 45 is connected to the coupling 5, and the other end of the fixed sleeve 45 is rotatably connected to the positioning seat 3 through the connecting bearing 6.

The inclined chamfered edge 43 can not only ensure the consistency of the chamfered edge of the center conductor, but also can be inserted into the chamfering device 4 when the center conductor is inserted into the chamfering device 4. As a further embodiment provided by the present invention, Figure 2 As shown, a coupling 5 is fixedly provided at the output end of the driving unit 2 to provide a guide for positioning the center conductor and prevent the center conductor from deviating.

[0030] Furthermore, a time relay 7 is fixedly provided on the outer wall on one side of the fixing seat 1, and the time relay 7 is electrically connected to the drive unit 2. It also includes a control switch, and the control switch and the time relay 7 are electrically connected. The time relay 7, the control switch, and the drive unit 2 are all electrically connected to the external power supply. The time relay 7 is powered on by the control switch, and the power-on time of the drive unit 2 is controlled by the time relay 7, so that the chamfering time of the center conductor can be controlled.

[0031] A drive unit controller is also provided inside the fixing seat 1 , and the rotation speed of the drive unit 2 can be adjusted by adjusting the drive unit controller, thereby achieving control of the speed of chamfering the center conductor.
