Description

Technical Field

[0001] This utility model relates to the technical field of wire harness processing equipment, specifically to a wire stripping pressure head device for wire harnesses. Background Technology

[0002] As a key component connecting various electrical devices in a circuit, the core function of wire harnesses is to transmit electrical signals and power, ensuring the normal operation of the equipment. In the wire harness manufacturing process, wire stripping and crimping are two indispensable steps. Wire stripping involves removing the outer sheath of the wire harness to expose the internal wires, creating conditions for subsequent electrical connections; crimping involves clamping and shaping the ends of the wires to achieve a reliable electrical connection and mechanical fixation with external interfaces.

[0003] In existing wire stripping and crimping technologies, the stripping and crimping equipment often operate independently. After the wire harness is stripped, it needs to be manually transported to the crimping station, resulting in low production efficiency. Frequent manual intervention also increases the potential risk of wire harness damage, limiting the scale of wire harness processing and production. Furthermore, wire harness specifications are diverse, requiring the purchase of multiple wire stripping machines of different specifications to meet production requirements when processing wire harnesses of different diameters, increasing production costs. Therefore, this paper proposes a wire stripping and crimping device for wire harnesses to address the aforementioned problems. Utility Model Content

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figures 1-4 As shown, a wire stripping and pressing head device for wire harnesses includes a base 1. A first platform 2, a second platform 7, a third platform 19, and a pressing platform 20 are sequentially fixedly installed on the upper surface of the base 1 along the wire harness conveying direction. Two rows of columns 3 are fixedly installed on the upper surface of the first platform 2. Positioning wheels 4 and conveying wheels 5 are sequentially rotatably connected to the upper end of each row of columns 3 along the wire harness conveying direction. A motor 6 is fixedly installed on the upper surface of the conveying wheels 5. The positioning wheels 4 and conveying wheels 5 are arranged in pairs, and the center lines of each pair of positioning wheels 4 and each pair of conveying wheels 5 coincide along the wire harness conveying direction. The rotation directions of each pair of positioning wheels 4 and each pair of conveying wheels 5 are opposite. After the operator passes the wire harness corresponding to the size of the cut 13 through the two paired positioning wheels 4, the motor 6 drives the conveying wheels 5 to convey the wire harness forward. A single machine can complete the wire stripping and pressing processes for various specifications of wire harnesses, reducing production costs to a certain extent.

[0024] Two guide rails 17 are fixedly installed on the upper surface of the second support platform 7. A limit plate 18 is fixedly installed on the side of the guide rail 17 near the first support platform 2, and a side plate 16 is fixedly connected to the side of the guide rail 17 away from the first support platform 2. A guide plate 8 is slidably connected to the outer surface of the guide rail 17. Three guide holes 9 are opened through the side of the guide plate 8, corresponding to the position of each set of conveying wheels 5. The diameter of the three guide holes 9 gradually decreases along the wire harness conveying direction until it is slightly smaller than the diameter of the three cuts 13. When the wire harness is conveyed to the guide hole 9, the wire harness will be further aligned with the cut 13 because the inlet and outlet of the guide hole 9 are different sizes. A lower cutting plate 10 is fixedly connected to the side of the guide plate 8 away from the first support platform 2. Two hydraulic rods 15 are fixedly installed on the right end of the side plate 16. The output ends of the second hydraulic rod 15 are fixedly connected to the left end of the lower cutting plate 10. Hydraulic rods 12 are fixedly installed at both ends of the lower cutting plate 10. The output ends of hydraulic rods 12 are fixedly connected to the upper cutting plate 11. The lower surface of the upper cutting plate 11 and the upper surface of the lower cutting plate 10 have three cuts 13. When the wire stripping point is transported to the cut 13, the motor 6 is turned off and hydraulic rods 12 are started. Hydraulic rods 12 shorten and drive the upper cutting plate 11 to close to the lower cutting plate 10, completing the wire cutting process. Hydraulic rods 12 extend and drive the upper cutting plate 11 to reset. Then, hydraulic rods 15 are started. Hydraulic rods 15 shorten and drive the lower cutting plate 10 to separate the stripped wire insulation from the wire. Hydraulic rods 15 extend and drive the lower cutting plate 10 to reset. The operator removes the wire insulation. Guide plates 141 are fixedly installed on the side of cut 13 away from guide plate 8. The inner diameter of the three guide plates 141 is the same as that of cut 13. Guide plate 2 142 is connected to the end of guide plate 141 away from cut 13. The end of guide plate 2 142 away from guide plate 141 is fixedly connected to the support platform 3 19. The upper surface of support platform 3 19 has a groove with a diameter consistent with the inner diameter of guide plate 2 142.

[0025] The upper surface of the pressure table 20 has three pressure grooves 21. The bottom surface of the three pressure grooves 21 is flush with the bottom end of the groove on the upper surface of the support platform 19. The support platform 19 is fixedly connected to the right side of the pressure table 20. Hydraulic rods 22 are fixedly installed at both ends of the pressure table 20. A crossbeam 23 is fixedly installed at the output end of the hydraulic rods 22. Three pressure blocks 24 are fixedly connected to the lower surface of the crossbeam 23 at the corresponding positions of the three pressure grooves 21. After the wire stripping process is completed, the motor 6 is started again, and the wire is moved along the guide plate 141 and guide plate 24. The grooves on the support platform 2 and 19 transport the wire harness end to the pressing groove 21. The motor 6 is turned off, and the hydraulic rod 22 is started. The hydraulic rod 22 shortens and drives the crossbeam 23 to close towards the pressing platform 20. The pressing block 24 presses the wire harness end. The hydraulic rod 22 extends and drives the crossbeam 23 to reset. The wire stripping and pressing processes are completed. The wire stripping and pressing processes can be completed at the same station without the need for secondary manual handling, which improves production efficiency, reduces the potential risk of wire harness damage, and makes the processing more scalable.

[0026] Working principle: In use, the operator passes the wire harness corresponding to the size of the cut 13 through two positioning wheels 4 that are in a set. The motor 6 drives the conveyor wheel 5 to transport the wire harness forward. When the wire harness is transported to the guide hole 9, the two openings of the guide hole 9 are of different sizes, so the wire harness will be further aligned with the cut 13. When the wire harness stripping point is transported to the cut 13, the motor 6 is turned off and the hydraulic rod 12 is started. The hydraulic rod 12 shortens, causing the upper cutting plate 11 to close with the lower cutting plate 10, completing the wire cutting process. The hydraulic rod 12 then extends, causing the upper cutting plate 11 to reset. Then the hydraulic rod 12 is started again. Hydraulic rod 215 shortens, causing the lower cutting plate 10 to separate the stripped wire insulation from the conductor. Hydraulic rod 215 then extends, causing the lower cutting plate 10 to reset. The operator removes the wire insulation and starts motor 6 again. The wire harness end is conveyed to the pressing groove 21 along the grooves on guide plate 141, guide plate 242, and bearing platform 319. Motor 6 is then stopped, and hydraulic rod 322 is started. Hydraulic rod 322 shortens, causing the crossbeam 23 to close towards the pressing platform 20. The pressing block 24 presses the wire harness end. Hydraulic rod 322 extends, causing the crossbeam 23 to reset. The wire stripping and pressing process is completed.
