Technical Field

[0001] This utility model relates to the field of automotive wiring harness crimping technology, specifically to an automatic crimping device for automotive wiring harnesses in one-time forming. Background Technology

[0002] Automotive wiring harnesses are the main network of automotive circuits. Without wiring harnesses, there would be no automotive circuits. A wiring harness is an assembly that connects circuits by crimping copper contact terminals with wires and cables, and then molding an insulator or adding an outer metal shell. The crimping of automotive wiring harnesses requires the use of automatic crimping equipment.

[0003] Although many procedures of existing automatic crimping equipment have been automated, some steps, such as wire harness feeding, still require manual adjustment. The large amount of manual intervention limits the automation level of automatic crimping equipment, and the high manpower input results in low efficiency of automotive wire harness crimping work. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic crimping device for one-time forming of automotive wiring harnesses, comprising a crimping machine and a mounting frame. The crimping machine has a fixed inlet. A material box is fixedly installed above the mounting frame. Two sets of symmetrically distributed limiting plates are slidably installed inside the material box. A rubber sheet is provided between the limiting plates and the material box, with both ends of the rubber sheet fixedly connected to the limiting plates and the material box, respectively. A discharge plate is slidably installed on the mounting frame, fitting snugly against the lower end of the material box. Two sets of symmetrically distributed adjusting plates are slidably installed inside the discharge plate, corresponding to the limiting plates. Two sets of symmetrically distributed lead screws are rotatably installed on the mounting frame, passing through both sides of the discharge plate and threadedly connected to it. Two sets of symmetrically distributed receiving plates are slidably installed on the mounting frame, corresponding to the inlet.

[0006] As a further preferred embodiment of this technical solution, the material box is provided with two sets of symmetrically distributed first bidirectional screws. The two ends of the two sets of first bidirectional screws pass through the material box and are rotatably connected to the material box through bearings. The two ends of the two sets of first bidirectional screws pass through two sets of limiting plates and are threadedly connected to the two sets of limiting plates respectively.

[0007] As a further preferred embodiment of this technical solution, the discharge plate is provided with a second bidirectional screw, the two ends of the second bidirectional screw passing through the discharge plate and rotatably connected to the discharge plate through bearings, and the two ends of the second bidirectional screw passing through two sets of adjusting plates and threadedly connected to the two sets of adjusting plates respectively.

[0008] As a further preferred embodiment of this technical solution, a first cylinder is fixedly mounted on the mounting bracket, and an elastic push block is provided on the mounting bracket. The two sets of receiving plates are symmetrically distributed about the elastic push block, and the elastic push block is connected to the output end of the piston rod of the first cylinder.

[0009] As a further preferred embodiment of this technical solution, two sets of symmetrically distributed slides are slidably installed inside the mounting frame. The two sets of slides are fixedly connected to two sets of receiving plates, and each set of slides is fixedly fitted with a stop block. Each set of slides is fitted with a spring, and the two ends of the spring are fixedly connected to the stop block and the mounting frame, respectively. Each set of slides is fixedly installed with a rack. A second cylinder is provided inside the mounting frame, and the lower rack is fixedly connected to the output end of the piston rod of the second cylinder.

[0010] As a further preferred embodiment of this technical solution, a first gear is provided between the two sets of racks. The first gear is rotatably connected to the mounting bracket via a rotating rod. The first gear meshes with the two sets of racks respectively. A torsion spring is sleeved on the rotating rod, and the two ends of the torsion spring are fixedly connected to the first gear and the mounting bracket respectively.

[0011] As a further preferred embodiment of this technical solution, the crimping machine is fixedly equipped with a mounting base, the mounting base is correspondingly arranged with the wire inlet, a mounting ring is rotatably installed inside the mounting base, a gear ring is sleeved on the mounting ring, the mounting base is provided with multiple sets of annularly distributed adjusting plates, the multiple sets of adjusting plates are rotatably connected to the mounting base through mounting shafts, and a second gear is sleeved on each of the multiple sets of mounting shafts, the multiple sets of second gears are meshed with the gear ring.

[0012] This utility model provides an automatic crimping device for one-time forming of automotive wiring harnesses, which has the following advantages:

[0013] (1) This utility model uses a material box to hold the wire harness waiting to be crimped, and adjusts the distance between the two sets of limiting plates and the distance between the two sets of adjusting plates on the discharge plate according to the actual thickness of the wire harness. With the sliding of the discharge plate on the mounting frame, when the gap between the two sets of adjusting plates is aligned with the gap between the limiting plates, the automatic discharge of a set of wire harnesses is completed. The discharged wire harnesses fall on the two sets of receiving plates on the mounting frame. There is a certain distance between the receiving plates and the bottom of the adjusting plates on the discharge plate. Therefore, the adjustment plates will not affect the discharge of a set of wire harnesses during the process of the adjusting plates sliding with the discharge plate. The wire harness has already landed on the receiving plate. Then, the first cylinder starts, driving the elastic pusher to slide and push the wire harness on the receiving plate towards the inlet, completing the subsequent automatic crimping operation. This process does not require manual operation by staff, reducing manual intervention and a large amount of manpower, effectively improving work efficiency. After the wire harness is crimped in the crimping machine, the second cylinder in the mounting frame starts, driving the rack to slide. In conjunction with the first gear, the two sets of slides drive the two sets of receiving plates to slide automatically to both sides. After the wire harness loses support on the receiving plate, it automatically falls to complete the discharge.

[0014] (2) This utility model achieves position adjustment of the wire harness entering the inlet by setting the mounting base and multiple sets of ring-shaped adjustment plates in the mounting base. The wire harness that automatically falls on the receiving plate with the cooperation of the material box and the discharge plate will inevitably have position deviation. At this time, the wire harness pushed by the elastic push block to the inlet is fixed in the center position of the mounting base by the synchronous rotation of multiple sets of adjustment plates in the mounting base, that is, aligned with the center position of the inlet, to ensure the accurate crimping processing of the wire harness in the crimping machine.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in this embodiment, an automatic crimping device for one-time forming of automotive wire harnesses includes a crimping machine 1 and a mounting frame 2. A wire inlet 22 is fixedly installed on the crimping machine 1. A material box 3 is fixedly installed above the mounting frame 2. Two sets of symmetrically distributed limiting plates 4 are slidably installed inside the material box 3. A rubber sheet 5 is provided between the limiting plates 4 and the material box 3, with both ends of the rubber sheet 5 fixedly connected to the limiting plates 4 and the material box 3, respectively. A discharge plate 7 is slidably installed on the mounting frame 2, fitting snugly against the lower end of the material box 3. Two sets of symmetrically distributed adjusting plates 9 are slidably installed inside the discharge plate 7, corresponding to the limiting plates 4. Two sets of symmetrically distributed lead screws 8 are rotatably installed on the mounting frame 2, passing through both sides of the discharge plate 7 and respectively connecting with... The discharge plate 7 is threaded. Two sets of symmetrically distributed receiving plates 13 are slidably mounted on the mounting frame 2, and the two sets of receiving plates 13 are corresponding to the inlet 22. The material box 3 is provided with two sets of symmetrically distributed first bidirectional screws 6. The two ends of the two sets of first bidirectional screws 6 pass through the material box 3 and are rotatably connected to the material box 3 through bearings. The two ends of the two sets of first bidirectional screws 6 pass through two sets of limiting plates 4 and are threadedly connected to the two sets of limiting plates 4 respectively. The discharge plate 7 is provided with a second bidirectional screw 10. The two ends of the second bidirectional screw 10 pass through the discharge plate 7 and are rotatably connected to the discharge plate 7 through bearings. The two ends of the second bidirectional screw 10 pass through two sets of adjusting plates 9 and are threadedly connected to the two sets of adjusting plates 9 respectively. A first cylinder is fixedly mounted on the mounting frame 2. 11. The mounting frame 2 is provided with an elastic push block 12. Two sets of receiving plates 13 are symmetrically distributed about the elastic push block 12. The elastic push block 12 is connected to the output end of the piston rod of the first cylinder 11. Two sets of symmetrically distributed slides 14 are slidably installed inside the mounting frame 2. The two sets of slides 14 are fixedly connected to the two sets of receiving plates 13 respectively. A stop block 15 is fixedly sleeved on each set of slides 14. A spring 16 is sleeved on each set of slides 14. The two ends of the spring 16 are fixedly connected to the stop block 15 and the mounting frame 2 respectively. A rack 17 is fixedly installed on each set of slides 14. A second cylinder 21 is provided inside the mounting frame 2. The lower rack 17 is fixedly connected to the output end of the piston rod of the second cylinder 21. A first gear 18 is provided between the two sets of racks 17. The first gear 18 is rotatably connected to the mounting frame 2 via the rotating rod 19. The first gear 18 meshes with two sets of racks 17. A torsion spring 20 is sleeved on the rotating rod 19. The two ends of the torsion spring 20 are fixedly connected to the first gear 18 and the mounting frame 2, respectively. The wire harness waiting to be crimped is held in the material box 3. The distance between the two sets of limiting plates 4 and the distance between the two sets of adjusting plates 9 on the discharge plate 7 are adjusted according to the actual thickness of the wire harness. With the sliding of the discharge plate 7 on the mounting frame 2, when the gap between the two sets of adjusting plates 9 is aligned with the gap between the limiting plates 4, the automatic discharge of a set of wire harnesses is completed. The discharged wire harnesses fall on the two sets of receiving plates 13 on the mounting frame 2. There is a certain distance between the receiving plates 13 and the bottom of the adjusting plates 9 on the discharge plate 7.Therefore, during the process of completing the discharge of a set of wire harnesses, the adjusting plate 9 slides with the discharge plate 7 without affecting the position of the wire harnesses already on the receiving plate 13. Subsequently, the first cylinder 11 is activated, driving the elastic pusher 12 to slide, pushing the wire harnesses on the receiving plate 13 towards the inlet 22, completing the subsequent automatic crimping operation. This process does not require manual operation by staff, reducing manual intervention and a large amount of manpower, effectively improving work efficiency. After the wire harnesses are crimped in the crimping machine 1, the second cylinder 21 in the mounting frame 2 is activated, driving the rack 17 to slide, which, in conjunction with the first gear 18, enables the two sets of slides 14 to automatically slide the two sets of receiving plates 13 to both sides. After losing support on the receiving plate 13, the wire harnesses automatically fall to complete the discharge.

[0024] like Figure 5 and Figure 6 As shown, a mounting base 23 is fixedly installed on the crimping machine 1. The mounting base 23 is correspondingly set with the wire inlet 22. A mounting ring 24 is rotatably installed inside the mounting base 23. A gear ring 25 is sleeved on the mounting ring 24. The mounting base 23 is provided with multiple sets of annularly distributed adjusting plates 26. The multiple sets of adjusting plates 26 are rotatably connected to the mounting base 23 through mounting shafts 27. A second gear 28 is sleeved on each of the multiple sets of mounting shafts 27. The multiple sets of second gears 28 are meshed with the gear ring 25. The wire harness that automatically falls onto the receiving plate 13 under the cooperation of box 3 and discharge plate 7 will inevitably have a positional deviation problem. At this time, the wire harness pushed towards the inlet 22 by the elastic push block 12 is driven by the motor in the mounting base 23 to rotate the mounting shaft 27. With the cooperation of the gear ring 25 and multiple sets of second gears 28, multiple sets of adjusting plates 26 are rotated synchronously, fixing the wire harness at the center position of the mounting base 23, that is, aligned with the center position of the inlet 22, to ensure the precise crimping processing of the wire harness in the crimping machine 1.

[0025] This utility model provides an automatic crimping device for automotive wire harnesses in one step. The specific working principle is as follows: The wire harnesses to be crimped are held in a hopper 3. The spacing between two sets of limiting plates 4 and the spacing between two sets of adjusting plates 9 on the discharge plate 7 are adjusted according to the actual thickness of the wire harness. This, combined with the sliding of the discharge plate 7 on the mounting frame 2, completes the automatic discharge of one set of wire harnesses when the gap between the two sets of adjusting plates 9 aligns with the gap between the limiting plates 4. The discharged wire harness lands on two sets of receiving plates 13 on the mounting frame 2. There is a certain distance between the receiving plates 13 and the bottom of the adjusting plates 9 on the discharge plate 7. Therefore, during the discharge of one set of wire harnesses and the sliding of the adjusting plates 9 with the discharge plate 7, the position of the wire harness already on the receiving plates 13 is not affected. Subsequently, the first cylinder 11 is activated, driving the elastic pusher 12 to slide, pushing the wire harness on the receiving plates 13 towards the wire inlet 22, completing the subsequent automatic crimping operation. The process does not require manual operation by staff, reducing human intervention and manpower input, effectively improving work efficiency. After the wire harness is crimped in the crimping machine 1, the second cylinder 21 in the mounting frame 2 starts and drives the rack 17 to slide. In conjunction with the first gear 18, the two sets of slides 14 drive the two sets of receiving plates 13 to slide automatically to both sides. After the wire harness loses support on the receiving plate 13, it falls automatically to complete the discharge. With the cooperation of the material box 3 and the discharge plate 7, the wire harness that automatically falls on the receiving plate 13 will inevitably have a positional deviation problem. At this time, the wire harness pushed by the elastic push block 12 towards the wire inlet 22 is driven by the motor in the mounting base 23 to rotate the mounting shaft 27. In conjunction with the gear ring 25 and multiple sets of second gears 28, multiple sets of adjusting plates 26 are rotated synchronously, fixing the wire harness in the center position of the mounting base 23, that is, aligned with the center position of the wire inlet 22, ensuring the precise crimping of the wire harness in the crimping machine 1.
