A clamping roller 208 is fixed between the two corresponding adjustment slide posts 207 in the horizontal direction. When the first mounting plate 201 is in the state of being moved, the adjusting rod 211 is pressed against the bottom surface of the adjusting rod 211, and the adjusting rod 211 is pressed against the bottom surface of the adjusting rod 211, thereby pressing the adjusting rod 211 against the bottom surface of the adjusting rod 211.

[0039] In an optional embodiment, a rubber layer is provided on the outside of each of the clamping rollers 208. The provision of the rubber layer increases the friction between the clamping rollers 208 and the cable, enabling the cable to be better positioned and supported, preventing it from moving laterally during the cutting process, thereby improving cutting accuracy.

[0040] Reference Figure 9-16 The end face positioning mechanism includes a displacement driving cylinder 302 installed on the top of the workbench 100 and located at one end of the clamping part 200. The output end of the displacement driving cylinder 302 is connected to the second mounting bracket 301. Guide rods 303 are fixed on the top of the workbench 100 and on both sides of the displacement driving cylinder 302. The second mounting bracket 301 is slidably connected to the guide rods 303.

A movable opening is opened on the top of the workbench 100, and the transmission belt 309 moves inside the movable opening to avoid interference during movement.

[0041] In an optional embodiment, a motor screw structure can be used to drive the second mounting frame 301 to perform displacement movement, thereby improving the accuracy of displacement adjustment of the second mounting frame 301. The motor is installed on the top of the workbench 100, and the screw is rotatably connected to the top of the workbench 100 and connected to the output end of the motor. The second mounting frame 301 is threadedly connected to the outside of the screw. When the motor is started, it drives the screw to rotate, thereby driving the second mounting frame 301 to perform displacement movement along the screw.

[0042] A fixed mounting cylinder 304 is fixed on the inner side of one end of the second mounting frame 301 close to the clamping portion 200, and a movable mounting cylinder 305 is provided on the inner side of the end of the second mounting frame 301 away from the clamping portion 200. The movable mounting cylinder 305 is rotatably connected to a gear disc 327 on the inner side of one end of the movable mounting cylinder 305 close to the fixed mounting cylinder 304. A second motor 329 is installed at the bottom of the fixed mounting cylinder 304. The output end of the second motor 329 is fixedly connected to a driving bevel gear 328, which is rotatably connected to the inner side of the fixed mounting cylinder 304. The driving bevel gear 328 is meshed with the gear disc 327. A plurality of sliders 330 are provided on the inner side of the movable mounting cylinder 305 and at one end of the gear disc 327. A threaded connection section 340 is provided on one end of the gear disc 327 close to the slider 330.

The slider 330 is connected to the toothed disc 327 through the cooperation between the threaded connection groove 341 and the threaded connection section 340. A positioning plate 331 is fixed to the end of the slider 330 away from the toothed disc 327. The positioning plate 331 and the slider 330 are slidably connected to the inner side of the movable mounting cylinder 305. When the second motor 329 is started, it can drive the driving bevel gear 328 to rotate, thereby driving the toothed disc 327 to rotate. Due to the cooperation between the threaded connection section 340 and the threaded connection groove 341, and at the same time, due to the limitation of the slider 330 by the movable mounting cylinder 305, when the toothed disc 327 rotates, it will drive several sliders 330 to move closer to or away from each other, thereby driving the positioning plate 331 to move closer to or away from each other. In actual use, the staff first passes the cable to be processed through the clamping portion 200 and extends it to a proper distance, and then starts the second motor 329 to drive the positioning plate 331 to clamp the shielding layer of the cable to be cut.

[0043] In an optional embodiment, a pressure sensor may be provided at the end of the positioning plate 331, and a controller may be provided to be electrically connected to the second motor 329. The pressure sensor is electrically connected to the controller. When the positioning plate 331 clamps the cable shielding layer, the pressure sensor is subjected to pressure. A preset pressure value may be set in advance. When the pressure sensor detects that the pressure reaches the preset value, the controller controls the second motor 329 to stop.

[0044] The inner sides of the ends of the positioning plates 331 close to each other are rotatably connected to the plurality of positioning auxiliary rollers 332. A micro switch 333 is embedded on the end surface of one of the positioning plates 331 facing inward and close to the toothed disc 327. The micro switch 333 is electrically connected to the displacement drive cylinder 302. During the positioning process of the welding end face, when the second motor 329 drives the positioning plate 331 to clamp the shielding layer of the cable to be cut, the displacement drive cylinder 302 is started to drive the second mounting frame 301 and the positioning plate 331 as a whole. Move toward the direction close to the welding end face, that is, close to the clamping part 200. During this process, the setting of the positioning auxiliary roller 332 can prevent the positioning plate 331 from being stuck with the cable. The auxiliary positioning plate 331 slides on the outside of the cable. When the displacement drive cylinder 302 drives the positioning plate 331 to move until the micro switch 333 contacts the welding end face of the connector bushing, the micro switch 333 starts to control the displacement drive cylinder 302 to stop. At this time, the position of the positioning plate 331 close to one end face of the slider 330 is the welding end face.

[0045] Reference Figure 14 The cutting mechanism includes a third mounting frame 334 fixed on the top of the movable mounting cylinder 305, a lifting drive cylinder 335 is installed on the top of the third mounting frame 334, the output end of the lifting drive cylinder 335 passes through the third mounting frame 334 and is fixed with a mounting angle plate 336, guide columns 337 are fixed on both sides of the top of the mounting angle plate 336, the setting of the guide columns 337 makes the movement of the third motor 338 and the cutting wheel 339 more stable, the guide columns 337 are slidably connected to the third mounting frame 334, a third motor 338 is installed at the bottom of the mounting angle plate 336, a cutting wheel 339 is fixed at the output end of the third motor 338, and the cutting wheel 339 is close to the fixed mounting cylinder 304 The end face is flush with the end face of the positioning plate 331 close to the fixed mounting cylinder 304, so that when the cutting wheel 339 cuts the cable shielding layer, the cut end face can remain flush with the welding end face; when the displacement drive cylinder 302 moves to the positioning plate 331 and touches the welding end face, it stops. At this time, the second motor 329 starts again to drive several positioning plates 331 away from each other, so as to reserve space for the cutting work and prevent the cutting wheel 339 from interfering with the positioning plate 331; when the cutting work is performed, the third motor 338 starts to drive the cutting wheel 339 to rotate, and at the same time the lifting drive cylinder 335 starts to drive the third motor 338 to gradually move downward close to the cable.

[0046] Reference Figure 8-12The positioning support mechanism includes an adjusting cylinder 2 310 installed on the top of the second mounting frame 301. The output end of the adjusting cylinder 2 310 extends into the inner side of the fixed mounting cylinder 304 and is fixed with a connecting strip 311. Fixed plates 312 are fixed on the fixed mounting cylinder 304 and on both sides of the connecting strip 311. The connecting strip 311 is slidably connected between the two fixed plates 312. The fixed plates 312 limit and guide the connecting strip 311 to make its movement more stable. An active cavity 313 is provided on the inner side of the connecting strip 311.

The driving rack 317 is fixed to the top of the inner side of the movable cavity 313, and the transmission rack 318 is fixed to the inner side of the installation cavity 315. When the driving rack 317 follows the connecting bar 311 to perform a lifting movement, the transmission rack 318 performs a lifting movement in the opposite direction under the action of the transmission gear 316, so that when the connecting bar 311 moves, the installation cavity 315 and the connecting bar 311 move synchronously in the opposite direction. The driving block 314 is provided with a first avoidance groove 319 on both sides for avoiding the transmission gear 316. The arrangement of the first avoidance groove 319 simultaneously avoids the rotating shafts at both ends of the transmission gear 316 and cooperates with the rotating shafts at both ends of the transmission gear 316 to guide the movement of the driving block 314.

The inner side of the top end of the clamping rod 323 is rotatably connected to an auxiliary roller 324 adapted to the driving inclined surface 321. A return spring 325 is provided between the top of the clamping rod 323 and the fixed installation cylinder 304. The two ends of the return spring 325 are respectively connected to the fixed installation cylinder 304 and the corresponding return spring 325. When the return spring When 325 is in a natural state, under its action, the bottom ends of the two clamping rods 323 separate from each other, and the top ends approach each other, so that the auxiliary roller 324 is in contact with the corresponding driving inclined surface 321. When the connecting bar 311 descends and drives the driving block 314 to move upward, the driving inclined surface 321 and the corresponding auxiliary roller 324 cooperate to make the bottom ends of the two clamping rods 323 approach each other and the top ends move away from each other and in contact with the driving inclined surface 321. In this way, the bottom end of the connecting bar 311 and the bottom ends of the two clamping rods 323 are close to each other, thereby clamping and positioning the cable assembly near the part to be cut, thereby improving its stability during cutting. In an optional embodiment, a positioning ball 326 is rollingly connected to the inner side of the bottom end of the connecting strip 311 and the bottom end of the clamping rod 323. The arrangement of the positioning ball 326 allows the cable to be positioned and clamped without large clamping force and without damaging the connector bushing and the cable, so that the cable end can be supported and clamped when the end face positioning mechanism supports the welding end face.

[0047] It should be noted that the clamping centers of the three positioning balls 326 and the clamping center of the clamping portion 200 are located on the same horizontal axis, so that the cable is kept horizontally placed.

[0048] In an optional embodiment, the movable mounting cylinder 305 is fixedly connected to the second mounting bracket 301, which is suitable for when there is no need to perform circumferential rotary cutting on the cable.

[0049] In an optional embodiment, the movable mounting cylinder 305 is rotatably connected to the second mounting frame 301, and a pulley 2 308 is fixed to the end of the movable mounting cylinder 305 away from the fixed mounting cylinder 304. A first motor 306 is installed at the bottom of the second mounting frame 301, and a pulley 1 307 is fixed to the output end of the first motor 306. A transmission belt 309 is connected to the outer sides of the pulley 1 307 and the pulley 2 308. When the cable needs to be circumferentially cut, the third motor 338 is started to drive the cutting wheel 339 to rotate, and the first motor 306 is started to drive the movable mounting cylinder 305 to rotate through the pulley 1 307, the pulley 2 308 and the transmission belt 309. At the same time, the lifting drive cylinder 335 is started to drive the cutting wheel 339 to gradually approach the cable, so that the cable can be circumferentially rotated and cut when the cable diameter is large.

[0050] The working principle of the tool for flattening the welding end face of a cable assembly according to the embodiment of the present application is as follows: when the end face of a cable assembly needs to be flattened, the worker first passes the cable assembly through the connecting angle plate 202 and then extends it into the inner side of the movable installation cylinder 305, so that the cable shielding layer to be cut is located between the plurality of positioning plates 331. Then, the adjusting cylinder 1 210 is activated and drives the adjusting rod 211 to move. The adjusting rod 211 drives the connecting angle plates 202 at both ends to rotate. Under the limiting action of the driving slide 205 and the guide slide 206, the clamping roller 208 follows the adjusting slide column 207 to move closer to each other, thereby clamping and supporting the tail of the cable to be processed; Then, the second air cylinder 310 is adjusted to start driving the connecting bar 311 downward. When the connecting bar 311 descends and drives the driving block 314 upward, the driving inclined surface 321 and the corresponding auxiliary roller 324 cooperate to make the bottom of the connecting bar 311 and the bottom ends of the two clamping rods 323 approach each other, thereby clamping the end position of the cable assembly. Then the second motor 329 starts to drive the bevel gear 328 to rotate, and drives the positioning plates 331 to approach each other and clamp the cable shielding layer through the transmission of the toothed disc 327 and the slider 330. Then the displacement drive cylinder 302 starts to drive the second mounting frame 301 and the positioning plates 331 to move as a whole toward the welding end face, that is, toward the clamping part 200. When the displacement drive cylinder 302 drives the positioning plates 331 to move until the micro switch 333 contacts the welding end face of the connector bushing, the micro switch 333 starts to control the displacement drive cylinder 302 to stop. At this time, the second motor 329 starts again to drive the plurality of positioning plates 331 away from each other. Then the third motor 338 is started to drive the cutting wheel 339 to rotate, and at the same time the lifting drive cylinder 335 is started to drive the third motor 338 to gradually move downward close to the cable to perform cutting work.
