[0024] In summary, the multi contact positioning cable accessory test detection device, in use, first of all, the cable is placed between the ring plate 402 on both sides of the chassis 1, and the cable accessory is placed above the center of the chassis 1, and the two ends of the cable are connected with the power supply device arranged on both sides of the chassis 1, start the motor 7, the motor 7 drives the bidirectional screw rod 8 to rotate, which can drive the two slide plates 2 to drive the clamping assembly 4 to move towards each other, clamp the cables connected on both sides of the cable accessory; When clamping the cable, the slide plate 2 can drive the vertical plate 401 to move synchronously through the sliding groove 3, and the ring plate 402 drives the clamp plate 406 to move close to the cable through the sleeve 404 and the plug column 405. If a clamp plate 406 first contacts the cable, the clamp plate 406 will stop moving and the plug column 405 will slide relatively in the sleeve 404, pressurizing the hydraulic oil in the sleeve 404, and making the hydraulic oil flow in the hydraulic network composed of the hydraulic cavity 403, the transfer pipe 409 and the center pipe 410, so that the hydraulic oil in the hydraulic network continuously pushes the clamp plates 406 that have not contacted the cable to move forward under the action of pressure until all the clamp plates 406 contact the surface of the cable; At this time, the motor 7 continues to drive the slide plate 2 to move through the bidirectional screw rod 8, and the vertical plate 401 and the ring plate 402 continue to move close to the cable. Under the action of the hydraulic network, the clamp plate 406 drives the plug column 405 to move correspondingly in the sleeve 404 until the clamp plate 406 and the plug column 405 are symmetrically distributed about the cable. At this time, all the clamp plates 406 can uniformly press the cable under the balanced pressure in the hydraulic network to avoid damage to the cable due to excessive local stress, and the clamping part of the cable can be centered at the same time to facilitate subsequent testing and detection of the cable. When the ring plate 402 moves, the slide block 6 can limit the slide plate 2 through the slide rail 5 to avoid the slide plate 2 from being skewed during movement, causing uneven stress on the cable; After clamping the cable, the slide plate 2 continues to move, which makes the clamp plate 406 pressurize the hydraulic oil in the sleeve 404 through the plug column 405, increases the pressure in the hydraulic network, and opens the pressure valve 411 in the center pipe 410 under the action of the increased pressure. The hydraulic oil can flow into the upper half of the center pipe 410, thereby pushing the plug rod 11 to move in the center pipe 410 and driving the lifting plate 12 to rise, so that the lifting plate 12 drives the rotating plate 15 to rotate. When the lifting plate 12 moves, the sleeve rod 13 can limit the lifting plate 12 through the sleeve pipe 14 to avoid deflection of the lifting plate 12. When the rotating plate 15 rotates, the inclined surface on the pressing block 16 can press the transfer pipe 409 to move away from the center pipe 410 on the base plate 1 and stretch the return spring 17, and then the slide rod 9 drives the vertical plate 401 to move on the slide plate 2 through the sliding groove 3, thereby pulling the cable to detect the firmness of the cable connected by the cable accessories; When the vertical plate 401 moves towards the opposite direction, the vertical plate 401 can slide on the slide rod 9 through the through slot 408, and the slide rod 9 does not hinder the vertical plate 401 from clamping the cable with the clamping plate 406. During the process of firmness detection, the slide rod 9 can not only move the vertical plate 401, but also keep the synchronization of the vertical plate 401, so as to avoid the cable from being deviated due to the deflection of the vertical plate 401. The slide frame 10 can limit the slide rod 9 to avoid the deflection of the slide rod 9 during the movement; During the lifting of the jacking plate 12, the jacking plate 12 can drive the support rod 19 to synchronously lift, so that the push block 20 drives the push switch 21 to rotate on the chassis 1. During the lifting of the support rod 19, the rack 22 can also drive the transmission wheel 23 to rotate on the chassis 1, and then the pinion 24 drives the support frame 25 to descend. The limiting rod 28 can limit the support rod 19 and the support frame 25 to avoid the deflection during the movement; After the connection firmness detection of the cable accessory, the jacking plate 12 moves, the push block 20 opens the push switch 21, and the two ends of the cable can be powered, so as to test the power supply of the cable. At this time, the jacking plate 12 and the support frame 25 drive the top plate 18 and the pressing plate 26 to contact the middle and both sides of the cable accessory, and the voltmeter 407 on the clamping plate 406 and the ammeter 27 on the top plate 18 and the pressing plate 26 can detect the leakage current of the cable and the surface of the cable accessory when they are pulled and bent; At the same time, with the continuous operation of the motor 7, the jacking plate 12 can drive the top plate 18 and the pressing plate 26 to synchronously apply force to the both ends and the center of the cable accessory for bending test, and the ammeter 27 and the voltmeter 407 can continuously detect the leakage current of the cable and the surface of the cable accessory when they are pulled and bent. The above detection is carried out after the clamping of the cable is completed, which can avoid accidents caused by loosening of the clamping during the detection process after the cable is powered on, and ensures the safety of the test and detection; After the detection is completed, the motor 7 drives the bidirectional screw rod 8 to rotate reversely, so as to move the slide plate 2 back. The hydraulic oil at the upper part of the center pipe 410 also flows back during the movement of the vertical plate 401 back, until the pressure in the hydraulic network decreases to the pressure of the pressure valve 411, and then the flow back is stopped. The hydraulic oil can drive the plug rod 11 to descend, and drive the support frame 25 to rise back through the pinion 24, the transmission wheel 23 and the rack 22, so as to release the top plate 18 and the pressing plate 26 from the cable accessory. After the slide plate 2 is completely reset, the clamping plate 406 releases the clamping of the cable, and the connection between the cable and the power supply device is disconnected, so that the cable and the cable accessory can be taken off from the device.
