[0038] A servo motor 1021 is fixedly installed on one side of the second support frame 202 away from the twisting frame 101, a driving pulley 1022 is fixedly installed on the output shaft of the servo motor 1021, a driven pulley 1023 is fixedly installed on one end of the outer wall of the twisting shaft 1019, and a power belt 1024 is commonly sleeved between the driven pulley 1023 and the driving pulley 1022;

[0039] The wire pulling component 2 includes a first support frame 201 and a second support frame 202 fixedly mounted on the top of the base 4, the first support frame 201 is located on the side of the second support frame 202 away from the twisting frame 101, and two front-to-back light rods 203 are fixedly mounted between the first support frame 201 and the second support frame 202. Slide sleeves 204 are slidably mounted on the outer walls of the two light rods 203, and a wire pulling seat 205 is commonly connected between the two slide sleeves 204. The bottom of the wire pulling seat 205 is provided with a hinge groove 206, and two front-to-back distributed clamps 207 are rotatably mounted inside the hinge groove 206, and the clamps 207 are close to the hinge groove 206. An incomplete gear 208 is fixedly installed in the middle of one end, a square slot 2051 is opened downwardly on the top of the wire puller seat 205, the bottom of the square slot 2051 is connected with the top of the hinge groove 206, a square rod 209 is slidably installed inside the square slot 2051, and a straight rack 2010 is fixedly installed on the front and back lower parts of the square rod 209, and the straight rack 2010 is meshed with the incomplete gear 208, and a force plate 2011 is fixedly installed on the lower part of the outer wall of the square rod 209, and two clamping springs 2012 distributed on the left and right are fixedly installed on the top of the force plate 2011, and the top of the clamping spring 2012 is fixedly connected to the top wall of the hinge groove 206;

[0040] Specifically, the two ends of the cable are placed between the two clamping plates 207 of the left and right wire pulling components 2, and then the two wire pulling seats 205 on the left and right are slid in opposite directions through the sliding connection between the sliding sleeve 204 and the light rod 203. When the two wire pulling seats 205 slide, the clamping plates 207 are driven to move together. At the same time, the guide wheel 2014 rolls along the inclined surface of the bottom of the wedge plate 2015, and under the action of the rebound force of the clamping spring 2012, the guide wheel 2014 rolls along the inclined surface of the wedge plate 2015. The rebound force of the clamping spring 2012 pushes the force-bearing plate 2011 and the square rod 209 to slide upward along the inner wall of the square slot 2051. The square rod 209 slides upward and drives the spur rack 2010 to move upward together, so that the two incomplete gears 208 rotate in opposite directions, thereby driving the two clamping plates 207 to clamp together in the middle until the clamping plates 207 are tightly clamped on the outer wall of the end of the cable. It should be noted that the center of the incomplete gear 208 in this device is concentric with the center of the rotating pin of the clamping plate 207 and the hinge groove 206 at the location;

[0041] After the two wire puller seats 205 are fixed, the middle part of the cable is placed between the front and rear inclined surfaces 1015, and the servo cylinder 1017 is started. The output rod of the servo cylinder 1017 pushes the hexagonal rod 109 to extend outward along the inner wall of the hexagonal hole 108, thereby pushing the top wire slot frame 1010 to drive the two wire harness blocks 1013 to move upward. The upward movement of the wire harness block 1013 drives the two inclined surfaces 1015 and the two clamping grooves 1016 to move upward together. During the upward movement of the two inclined surfaces 1015, the middle part of the cable is pushed upward until the cable is straightened and then continued to be pushed. The outer wall of the cable is subjected to the wedge force of the two inclined surfaces 1015, and the two wire harness blocks 1013 are pulled upward. 013 expands, during which the spring 1014 is compressed. After the two harness blocks 1013 expand, the cables immediately slide into the two clamping grooves 1016, and the two harness blocks 1013 are pushed to close to the middle under the action of the rebound force of the spring 1014 to clamp the cables to ensure that the middle of the cables will not loosen. Then the inspector controls the servo cylinder 1017 through the computer to set the thrust value of the servo cylinder 1017. The output rod of the servo cylinder 1017 pushes the hexagonal rod 109 and the top wire trough frame 1010 to move upward. The top wire trough frame 1010 moves upward to drive the two harness blocks 1013 to move together, exerting an upward thrust on the middle of the cables, and testing the cable's tensile strength.

[0042] After the cable tensile strength test is completed, the servo motor 1021 is started, and the output shaft of the servo motor 1021 drives the active pulley 1022 to rotate. The active pulley 1022 rotates through the power belt 1024 to drive the driven pulley 1023 to rotate. The driven pulley 1023 rotates through the torsion shaft 1019 to drive the active gear 1020 to rotate. The active gear 1020 rotates to drive the driven gear ring 1018 meshing therewith to rotate together with the torsion ring 106. The torsion ring 106 rotates to drive the U-shaped frame 107 to rotate together. The rotation of the U-shaped frame 107 drives the servo cylinder 1017, the hexagonal rod 109, the top wire trough frame 1010 and the two wire harness blocks 1013 to rotate together. When the two wire harness blocks 1013 rotate with the twisting ring 106, they drive the clamped cables to rotate together, causing the cables to twist. The torsional quality test of the conductors realizes that the same device can not only perform tensile test on the cables, but also further perform torsional test on the cables without disassembling them, thereby improving the convenience of cable testing.

[0043] A threaded hole is opened on the outer wall of one of the sliding sleeves 204, and a fastening bolt 2016 is provided on the outer wall of the sliding sleeve 204. The fastening bolt 2016 is threadedly screwed with the sliding sleeve 204 through the threaded hole, and the end of the fastening bolt 2016 abuts against the outer wall of the light rod 203. When the two wire pulling seats 205 move to the outermost ends, the two fastening bolts 2016 are tightened so that the ends of the fastening bolts 2016 are tightly attached to the periphery of the light rod 203, thereby positioning the two wire pulling seats 205 to avoid unnecessary movement of the two wire pulling seats 205.

[0044] Embodiment 2: The wire holding component 3 includes four support plates 301 fixedly mounted on the top of the base 4, the four support plates 301 are symmetrically distributed in pairs, and a slide cylinder 302 is fixedly mounted on the top of the support plates 301, and a slide rod 303 is slidably mounted on the inner wall of the slide cylinder 302, wherein the two slide rods 303 located at the front and the two slide rods 303 located at the rear are connected to a wire holding plate 304 at one end, there are two wire holding plates 304, and a wire holding groove 3041 is provided on the side surface of the two wire holding plates 304 that are close to each other, and a reset spring 305 is provided on the outer periphery of the slide rod 303, and the reset spring 305 is fixedly mounted between the slide cylinder 302 and the wire holding plate 304;

[0045] A wedge block 306 is fixedly installed in the middle of the side surface away from the two wire holding plates 304, and a closing block 307 is slidably installed on the outer wall of the two bare rods 203. The closing block 307 is located on the side of the wire pulling seat 205 close to the twisting frame 101. Two fixing holes 3071 distributed front and back are penetrated downward from the top of the closing block 307. The inner wall of the fixing hole 3071 is fixedly installed with a closing rod 308. The position of the closing rod 308 is adapted to the position of the wedge block 306. A pull rope 309 is fixedly installed between the closing block 307 and the wire pulling seat 205.

[0046] Specifically, in this embodiment, when the wire pull seat 205 drives the two clamping plates 207 to slide the clamped cables along the light rod 203, the cables pass through the two front and rear wire gripping plates 304. During this period, the pull rope 309 is gradually stretched and straightened by the movement of the wire pull seat 205. The straightened pull rope 309 moves with the wire pull seat 205, thereby pulling the closing block 307 and the two closing rods 308 to move along the light rod 203. When the wire pull seat 205 just slides out from between the two wire gripping plates 304, the two closing rods 308 just move. Until it contacts the wedge surfaces of the two wedge blocks 306, so that when the wire pulling seat 205 continues to move, the two closing rods 308 and the wedge force of the two wedge blocks 306 push the two wire holding plates 304 to move toward the middle until the two wire holding plates 304 are completely merged and the wire pulling seat 205 stops sliding. At this time, the two wire holding grooves 3041 just fit together and are sleeved on the periphery of the cable to restrain the cable, thereby avoiding the spiral twisting of the cable and the occurrence of knotting problems during the process of testing the anti-torsion quality, thereby ensuring the stability of the cable anti-torsion quality detection.

[0047] Embodiment 3: The bottom height of the wedge block 306 is higher than the top height of the slide cylinder 302, and the bottom height of the closing rod 308 is flush with the bottom height of the wedge block 306;

[0048] Specifically, the present embodiment is designed such that when the closing rod 308 moves toward the two wedge blocks 306, it is ensured that the bottom of the closing rod 308 will not contact the top of the slide 302, thereby ensuring that the closing rod 308 is not interfered with by the slide 302 when moving. At the same time, the bottom of the closing rod 308 is flush with the bottom of the wedge block 306, ensuring that the outer wall of the closing rod 308 can contact the wedge surface of the wedge block 306, thereby pushing the wedge block 306 and the wire gripping plate 304 to move toward the middle.

[0049] Embodiment 4: A winding post 5 is fixedly installed inside the second support frame 202, and the height of the winding post 5 corresponds to the height of the two wire holding grooves 3041;

[0050] Specifically, during detection, a section of detection cable is taken out, the cable is passed through the bottom of the left and right winding poles 5, and the two ends of the cable are respectively placed between the two clamping plates 207 of the left and right wire pulling parts 2, and the two clamping plates 207 clamp the ends of the cable and move the two ends of the cable to both sides. Then, after the top wire part 1 pushes up the middle part of the cable, the cable is straightened. Thereafter, due to the winding support of the two winding poles 5 on the cable and the clamping effect of the clamping plates 207 on the cable, the cable is just located between the two front and rear wire holding grooves 3041, ensuring that when the two wire holding plates 304 move toward the middle, on the one hand, the wire holding plates 304 will not clamp the wire skin of the cable, and on the other hand, the cable can be accurately positioned between the two wire holding grooves 3041.

[0051] When the cable quality detection device of the present scheme is working, a section of detection cable is taken out, and the cable is passed through the bottom of the left and right winding poles 5, and the two ends of the cable are respectively placed between the two clamping plates 207 of the left and right wire pulling components 2, and then the left and right wire pulling seats 205 are slid in opposite directions through the sliding connection relationship between the sliding sleeve 204 and the light rod 203. When the two wire pulling seats 205 slide, the clamping plates 207 are driven to move together. At the same time, the guide wheel 2014 rolls along the inclined surface at the bottom of the wedge plate 2015, and under the action of the rebound force of the clamping spring 2012, the guide wheel 2014 rolls along the inclined surface of the wedge plate 2015, and the rebound force of the clamping spring 2012 pushes the clamping spring 2012 to move. The force plate 2011 together with the square rod 209 slides upward along the inner wall of the square slot 2051, and the square rod 209 slides upward to drive the spur rack 2010 to move upward together, so that the two incomplete gears 208 rotate in opposite directions, thereby driving the two clamping plates 207 to clamp together in the middle until the clamping plates 207 are tightly clamped on the outer wall of the end of the cable. It should be noted that in this device, the center of the incomplete gear 208 is concentric with the center of the rotating pin of the clamping plate 207 and the hinge groove 206 at the position. When the two wire pulling seats 205 move to the outermost end, the two fastening bolts 2016 are tightened so that the ends of the fastening bolts 2016 are tightly attached to the outer periphery of the light rod 203, thereby positioning the two wire pulling seats 205;

[0052] After the two wire puller seats 205 are fixed, the middle part of the cable is placed between the front and rear inclined surfaces 1015, and the servo cylinder 1017 is started. The output rod of the servo cylinder 1017 pushes the hexagonal rod 109 to extend outward along the inner wall of the hexagonal hole 108, thereby pushing the top wire slot frame 1010 to drive the two wire harness blocks 1013 to move upward. The upward movement of the wire harness block 1013 drives the two inclined surfaces 1015 and the two clamping grooves 1016 to move upward together. During the upward movement of the two inclined surfaces 1015, the middle part of the cable is pushed upward until the cable is straightened and then continued to be pushed. The outer wall of the cable is subjected to the wedge force of the two inclined surfaces 1015, and the two wire harness blocks 1013 are pulled upward. 013 expands, during which the spring 1014 is compressed. After the two harness blocks 1013 expand, the cables immediately slide into the two clamping grooves 1016, and the two harness blocks 1013 are pushed to close to the middle under the action of the rebound force of the spring 1014 to clamp the cables to ensure that the middle of the cables will not loosen. Then the inspector controls the servo cylinder 1017 through the computer to set the thrust value of the servo cylinder 1017. The output rod of the servo cylinder 1017 pushes the hexagonal rod 109 and the top wire trough frame 1010 to move upward. The top wire trough frame 1010 moves upward to drive the two harness blocks 1013 to move together, exerting an upward thrust on the middle of the cables, and testing the cable's tensile strength.

[0053] After the cable tensile strength test is completed, the servo motor 1021 is started, and the output shaft of the servo motor 1021 drives the active pulley 1022 to rotate. The active pulley 1022 rotates through the power belt 1024 to drive the driven pulley 1023 to rotate. The driven pulley 1023 rotates through the torsion shaft 1019 to drive the active gear 1020 to rotate. The active gear 1020 rotates to drive the driven gear ring 1018 meshing therewith to rotate together with the torsion ring 106. The torsion ring 106 rotates to drive the U-shaped frame 107 to rotate together. The rotation of the frame 107 drives the servo cylinder 1017, the hexagonal rod 109, the top wire trough frame 1010 and the two wire bundle blocks 1013 to rotate together. When the two wire bundle blocks 1013 rotate with the twist ring 106, they drive the clamped cables to rotate together, causing the cables to twist, thereby realizing the anti-torsion quality detection of the wires. The same device can not only perform anti-twist detection on the cables on the basis of performing anti-tensile detection on the cables, but also further perform anti-torsion detection on the cables without disassembly, thereby improving the convenience of cable detection.
