Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness processing, and more specifically, to an automotive wiring harness straightening and cutting device. Background Technology

[0002] Automotive wiring harnesses are the main network components of automotive circuits. They consist of copper-plated contact terminals (connectors) crimped to wires and cables, and then covered with plastic insulation or an outer metal shell, bundled together to form a circuit connection.

[0003] The raw material for automotive wiring harness processing is cables. Bundles of cables are laid out and cut according to requirements, resulting in different lengths for the specifications of the wiring harness. In existing technology, the cutting of wiring harnesses is generally done by first straightening and then cutting. The length of straightening is the length of the cut cable. Straightening is usually done by horizontal movement, and the distance of horizontal movement is the length of the cable that can be cut. When it is necessary to cut a longer cable, the movement distance of the moving mechanism or the assembly position of the cutting mechanism can only be changed. This requires stopping the machine for reassembly and adjustment, which wastes processing time.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0022] The invention will now be further described with reference to the accompanying drawings and specific embodiments: Example 1: Please refer to Figures 1 to 9 According to an embodiment of the present invention, an automotive wiring harness straightening and cutting device includes a base plate 1. Support frames 2 are fixedly installed on both sides of the top of the base plate 1 along its length. A transverse frame 3 is slidably installed between the support frames 2. A cable pulling mechanism 4 is fixedly installed on the top of the transverse frame 3. A cutting mechanism 5 is fixedly installed at one end of the top of the base plate 1. The cable end is passed through the cutting mechanism 5 via the cable pulling mechanism. Then, the cable pulling mechanism 4 is adjusted to be closer to the cutting mechanism 5, and the cable end is clamped and fixed by the cable pulling mechanism 4. Then, the cable pulling mechanism 4 is adjusted away from the cutting mechanism 5 to straighten the cable. When the cable pulling mechanism 4 moves away from the cutting mechanism 5, the cutting mechanism 5 is activated to cut the cable. Then, the cable pulling mechanism 4 releases the cable end, and the cut cable falls onto the base plate 1, awaiting collection to provide raw materials for subsequent wiring harness processing.

[0023] The wire pulling mechanism 4 includes a vertical plate 6 fixedly installed on the top of the transverse frame 3. The vertical plate 6 is positioned directly opposite the cutting mechanism 5. Extension blocks 7 are fixedly installed at both ends of the side of the vertical plate 6 facing the cutting mechanism 5. A crossbar 8 is fixedly installed between the extension blocks 7. Several transverse blocks 9 are slidably installed outside the crossbar 8. A wire clamping assembly 10 is fixedly installed at the bottom of the end of the transverse blocks 9 facing the cutting mechanism 5. An adjusting plate 11 is also provided at the top between the extension blocks 7. The top of the transverse blocks 9 is connected to the adjusting plate 11. The spacing between the transverse blocks 9 can be changed by adjusting the plate 11, thereby adjusting the position of the wire clamping assembly 10. The wire clamping assembly 10 can be adjusted according to the position of the incoming wire.

[0024] A sliding sleeve 13 is fixedly installed through the transverse block 9. The sliding sleeve 13 is slidably sleeved on the outside of the crossbar 8. A fixing block 14 is fixedly installed on the top of the transverse block 9. A guide post 15 is rotatably installed on the top of the fixing block 14. A guide hole 16 is symmetrically opened along the center of the adjusting plate 11. The number of guide holes 16 is equal to the number of transverse blocks 9 and corresponds one-to-one. The guide holes 16 are opened in a radiating pattern on the adjusting plate 11. The guide post 15 is slidably installed in the guide hole 16. An adjusting cylinder 12 is fixedly installed at the top center of the end of the vertical plate 6 away from the cutting mechanism 5. The output shaft end of the adjusting cylinder 12 is set through the vertical plate 6. A connecting block 17 is fixedly installed in the middle of the end of the adjusting plate 11 near the vertical plate 6. The top of the connecting block 17 is fixedly connected to the output shaft end of the adjusting cylinder 12. A first sliding seat 18 is fixedly installed at both ends of the bottom of the adjusting plate 11. A first slide rail 19 is fixedly installed on the top of the extension block 7 along its length direction. The first sliding seat 18 is slidably installed on the first slide rail 19. The start-up adjustment cylinder 12 can drive the adjustment plate 11 to move horizontally through the connecting block 17. The movement of the adjustment plate 11 will drive the guide post 15 to move through the guide hole 16. The movement of the guide post 15 can then drive the transverse block 9 to slide and adjust on the crossbar 8 through the fixing block 14, thereby changing the spacing between the clamping components 10.

[0025] The cable clamping assembly 10 includes an assembly block 20 fixedly mounted on a horizontal moving block 9. Vertically arranged second slide rails 21 are fixedly mounted on both side walls of the assembly block 20 at the end furthest from the horizontal moving block 9. A second slide block 22 is slidably mounted on the second slide rail 21, and an assembly plate 23 is fixedly mounted on the second slide block 22. Clamping arms 24 are fixedly mounted on the end of the assembly plate 23 furthest from the horizontal moving block 9, and the ends of the two clamping arms 24 furthest from the assembly plate 23 are vertically opposite each other. By adjusting the two assembly plates 23 vertically, the corresponding clamping arms 24 can be adjusted synchronously, thereby clamping the cable ends using the ends of the two clamping arms 24.

[0026] A notch 27 is provided in the middle of the assembly block 20. An assembly accessory 25 is fixedly installed inside the assembly block 20 near the transverse block 9. A push rod 26 is slidably inserted inside the assembly accessory 25. One end of the push rod 26 is located in the notch 27, and the other end of the push rod 26 is inserted through the bottom of the transverse block 9. A horizontally arranged push-pull shaft 28 is fixedly installed on the end of the push rod 26 located inside the notch 27. A hinge shaft 30 is installed on the outer wall of the assembly block 20. A connecting plate 29 is installed at a right angle on the hinge shaft 30. A slot 31 is provided at the end of the connecting plate 29 near the push rod 26 and at the end of the connecting plate 29 away from the clamping arm 24. The end of the connecting plate 29 near the assembly plate 23 is slidably locked in the slot 31 on the assembly plate 23, and the end of the push-pull shaft 28 is slidably locked in the corresponding slot 31 of the connecting plate 29. When the push rod 26 is pushed by an external force, the push rod 26 can move synchronously through the push-pull shaft 28 at its end. The push-pull shaft 28 then drives the connecting plate 29 to rotate on the hinge shaft 30 through the bayonet 31. The end of the connecting plate 29 away from the push-pull shaft 28 can then drive the assembly plate 23 to move through the bayonet 31 on the corresponding assembly plate 23. This allows the assembly plate 23 to slide on the first slide rail 19 through the first slide block 18, thereby changing the distance between the two clamping arms 24 and achieving clamping of the cable end.

[0027] A collar 32 is fitted around the outside of the push rod 26, and the collar 32 is tightly abutted against the end of the mounting bracket 25. A retaining ring 33 is fixedly installed at the end of the push rod 26 away from the push-pull shaft 28. A return spring 34 is provided between the retaining ring 33 and the collar 32, and the return spring 34 is fitted around the outside of the push rod 26. The return spring 34 can push the retaining ring 33 through the collar 32, thereby causing the push rod 26 to move automatically away from the clamping arm 24. When no external force is applied to the push rod 26, the two clamping arms 24 will automatically move closer to each other and abut tightly, thereby automatically clamping the end of the cable.

[0028] A right-angle plate 35 is fixedly installed at the bottom center of the end face of the upright plate 6 away from the cutting mechanism 5. The bottom of the right-angle plate 35 is fixedly installed on the transverse frame 3. A horizontally arranged clamping cylinder 36 is fixedly installed on the right-angle plate 35. The output shaft end of the clamping cylinder 36 passes through the right-angle plate 35 and is fixedly installed with a connecting rod 37. A push plate 38 is fixedly installed at the end of the connecting rod 37. The end of the push plate 38 away from the connecting rod 37 is set tightly against the end of the top rod 26. When the clamping cylinder 36 is activated, the clamping cylinder 36 can drive the push plate 38 to adjust the top rod 26, thereby adjusting all the clamping arms 24 so that the clamping arms 24 are separated from each other, and thus can clamp the cable end.

[0029] A smooth, wear-resistant pad is fixedly attached to one end face of the push plate 38 facing the push rod 26. The wear-resistant pad reduces friction between the push rod 26 and the push plate 38 when it moves with the transverse block 9. First guide rods 39 are fixedly installed at both ends of the end face of the push plate 38 facing the vertical plate 6. A first guide sleeve 40 is fixedly installed through the vertical plate 6, with the first guide rods 39 passing through the first guide sleeve 40. The arrangement of the first guide rods 39 and the first guide sleeve 40 makes the movement, adjustment, and assembly of the push plate 38 more stable.

[0030] Through the above-described solution of the present invention, the cable pulling mechanism 4 provided by the present invention can change the distance between adjacent clamping components 10 according to the specific position of the incoming line, so that the clamping arm 24 at the end of the clamping component 10 can be aligned with the end of the cable for clamping. The adjustment and opening of the clamping arm 24 only requires pushing the push plate 38. When the push plate 38 moves away from the top rod 26, the end of the clamping arm 24 will automatically move closer, thereby achieving automatic clamping of the cable end through the return spring 34. Moreover, all clamping components 10 can be uniformly adjusted, and no additional control components are required, saving costs.

[0031] Example 2: Please refer to Figures 11 to 13 In embodiment one, the top of the base plate 1 is provided with a wiring groove 101. The support frame 2 includes uprights 201 fixedly installed on the top of the base plate 1 and arranged on both sides of the base plate 1 along its length. A strip plate 202 arranged along the length of the base plate 1 is fixedly installed at the top end of the uprights 201. A third slide rail 203 is fixedly installed on the bottom side of the strip plate 202 near the center of the base plate 1. The top two ends of the transverse frame 3 are slidably arranged on the third slide rail 203. A motor 204 is fixedly installed on the top of the strip plate 202 near one end. The output shaft end of the motor 204 passes through the strip plate 202 and is fixedly installed with a drive pulley 205. A driven pulley 206 is rotatably installed on the bottom end of the strip plate 202 away from the drive pulley 205. The drive pulley 205 and the driven pulley 206 are connected by a transmission belt 207. The end of the transverse frame 3 is fixedly connected to the transmission belt 207 that is close to it.

[0032] Start the motor 204. The motor 204 can drive the transmission belt 207 to move through the driving pulley 205 and the driven pulley 206. The movement of the transmission belt 207 will cause the transverse frame 3 to slide and adjust on the third slide rail 203. When the cable pulling mechanism 4 clamps the end of the cable, the cable can be straightened by adjusting the movement of the transverse frame 3.

[0033] The transverse frame 3 includes a horizontally arranged transverse plate 301. A third slide block 302 is fixedly installed on the top of the transverse plate 301 near the two side strip plates 202. The third slide block 302 is slidably mounted on a third slide rail 203. A lifting cylinder 303 is fixedly installed at the bottom center of the transverse plate 301. The output shaft end of the lifting cylinder 303 passes through the transverse plate 301 and is fixedly installed on a lifting plate 304. The bottom of the vertical plate 6 and the bottom of the right-angle plate 35 are both fixedly installed on the top. On the lifting plate 304, a vertical block 305 is fixedly installed on the outside of one end of the transverse plate 301 near the strip plate 202, and a clamping block 306 is fixedly installed on the outside of the other end of the vertical block 305 away from the transverse plate 301. The transmission belt 207 is fixedly disposed between the vertical block 305 and the clamping block 306 on one side near the transverse plate 301. A strip hole 208 is provided on the strip plate 202 along its length direction. The top of the vertical block 305 and the top of the clamping block 306 are disposed in the strip hole 208.

[0034] The lifting cylinder 303 can adjust the height of the lifting plate 304, thereby changing the height of the cable pulling mechanism 4 when it straightens the cable, so that the cable is stretched by a distance greater than the actual horizontal movement distance of the transverse frame 3, and can straighten and cut longer cables as needed.

[0035] A second guide rod 307 is fixedly installed at the four bottom corners of the lifting plate 304, and a second guide sleeve 308 is fixedly installed near the four corners of the transverse plate 301, with the second guide sleeve 308 penetrating through the transverse plate 301. The bottom of the second guide rod 307 penetrates through the second guide sleeve 308. The arrangement of the second guide rod 307 and the second guide sleeve 308 can make the lifting of the lifting plate 304 more stable.

[0036] Through the above-described solution of the present invention, the horizontal moving frame 3 provided by the present invention can not only drive the cable pulling mechanism 4 to move horizontally, but also adjust the height of the cable pulling mechanism 4 through the lifting plate 304. This allows the cable pulling mechanism 4 to change the height of the cable end when straightening the cable, so that the cable is stretched by a distance greater than the actual horizontal moving distance of the horizontal moving frame 3. Longer specifications of cable can be straightened and cut according to requirements.

[0037] Example 3: Please refer to Figure 14For Embodiment 1 and Embodiment 2, the cutting mechanism 5 includes a support plate 501 fixedly installed on the base plate 1. A horizontal strip 502 arranged along the width direction of the base plate 1 is fixedly installed on the top of the support plate 501. Vertical plates 503 are fixedly installed at both ends of the top of the horizontal strip 502. A top plate 504 is fixedly installed at the top end of the vertical plate 503. A first lifting plate 506 is provided above the horizontal strip 502. A cutting seat 507 is fixedly installed on the top of the first lifting plate 506. A second lifting plate 509 is provided below the top plate 504. A leveling cylinder 510 is fixedly installed near both ends of the top of the second lifting plate 509. The output shaft end of the leveling cylinder 510 passes through the second lifting plate 509 and is fixedly installed with a hanging rod 511. A cutter 512 is fixedly installed between the two hanging rods 511. By changing the distance between the first lifting plate 506 and the second lifting plate 509, the cutter 512 can be moved toward the cutting seat 507, thereby realizing the cutting operation of the cable.

[0038] A cutting cylinder 508 is fixedly installed at the top center of the top plate 504. The output shaft end of the cutting cylinder 508 passes through the top plate 504. The top of the second lifting plate 509 is fixedly installed at the output shaft end of the cutting cylinder 508. A height adjustment cylinder 505 is fixedly installed at the bottom center of the horizontal bar 502. The output shaft end of the height adjustment cylinder 505 passes through the horizontal bar 502 and is fixedly connected to the bottom of the first lifting plate 506. The height adjustment cylinder 505 can change the height of the cutting seat 507. When the cable pulling mechanism 4 is raised by the lifting plate 304, the height of the cutting seat 507 can be changed accordingly, so that the cable can always be positioned at the top of the cutting seat 507.

[0039] A third guide sleeve 513 is installed through both ends of the first lifting plate 506, and a fourth guide sleeve 514 is installed through both ends of the second lifting plate 509. A vertical rod 515 is fixedly installed between the horizontal bar 502 and the top plate 504, near the vertical plate 503. The third guide sleeve 513 and the fourth guide sleeve 514 are slidably sleeved on the outside of the vertical rod 515. The arrangement of the vertical rod 515 and the third guide sleeve 513 and the fourth guide sleeve 514 can make the movement and adjustment of the first lifting plate 506 and the second lifting plate 509 more stable.

[0040] The top of the cutting seat 507 has a cutting groove 516 that runs along its length, and the cutter 512 is positioned directly opposite the cutting groove 516. The cutting groove 516 ensures smooth cutting of the cable by the cutter 512.

[0041] Through the above-described solution of the present invention, the height of the cutting seat 507 provided by the present invention can be adjusted, so that when the cable pulling mechanism 4 is driven to rise by the lifting plate 304, the height of the cutting seat 507 can be changed accordingly, so that the cable can always be set at the top of the cutting seat 507, ensuring the stability of cutting.

[0042] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below.

[0043] The cable pulling mechanism 4 of this invention can change the distance between adjacent clamping components 10 according to the specific position of the incoming cable, so that the clamping arm 24 at the end of the clamping component 10 can be aligned with the end of the cable for clamping. The adjustment and opening of the clamping arm 24 only requires pushing the push plate 38. When the push plate 38 moves away from the top rod 26, the end of the clamping arm 24 will automatically move closer, thereby achieving automatic clamping of the cable end through the return spring 34. Moreover, all clamping components 10 can be uniformly adjusted, and no additional control components are required, saving costs.

[0044] The horizontal moving frame 3 of this invention can not only drive the cable pulling mechanism 4 to move horizontally, but also adjust the height of the cable pulling mechanism 4 through the lifting plate 304. This allows the cable pulling mechanism 4 to change the height of the cable end when straightening the cable, so that the cable is stretched by a distance greater than the actual horizontal moving distance of the horizontal moving frame 3. Longer cables can be straightened and cut according to requirements.

[0045] The height of the cutting seat 507 provided in this invention is adjustable, so that when the cable pulling mechanism 4 is raised by the lifting plate 304, the height of the cutting seat 507 can be changed accordingly, so that the cable can always be set at the top of the cutting seat 507, ensuring the stability of cutting.
