Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire harness crimping technology, and in particular to a wire harness crimping mechanism that prevents hand compression. Background Technology
[0002] The uniqueness of wiring harnesses in new energy vehicles is mainly reflected in the high-voltage wiring harness section. There are three ways to connect high-voltage wires and terminals: welding, crimping, and mechanical connection. Among them, crimping connection uses a crimping mechanism to deform the connector joint and press it onto the wire through pressure, so that the connector terminal and the wire form a mechanical connection, giving it good mechanical and electrical properties.
[0003] Currently, existing wire harness crimping mechanisms require workers to place the wire harness and terminals at the crimping point for crimping. This poses a risk of the wire harness being crushed by the crimping mechanism during the crimping process, which is detrimental to the safe application of wire harness and terminal connection. Therefore, in order to advance industry technology, better realize the wire harness and terminal crimping function, and improve core technology competitiveness, this application proposes a new implementation scheme that differs from the feeding structure and application method of the crimping mechanism in the prior art. Utility Model Content
[0004] The purpose of this invention is to solve the problem that there is a risk of the wire harness being crushed by the crimping mechanism during the crimping process when using existing wire harness crimping mechanisms, and to propose a wire harness crimping mechanism that prevents the hand from being crushed.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A wire harness crimping mechanism for preventing hand crushing includes a vertical frame. Hydraulic cylinders are fixedly connected to the top and bottom inner walls of the vertical frame. A crimping connector is fixedly connected to one end of the hydraulic rod of each hydraulic cylinder. A horizontal frame is fixedly connected between the two inner walls of the vertical frame. Multiple guide rods are fixedly connected between the two inner walls of the horizontal frame. A sliding plate is slidably sleeved between the multiple guide rods. The sliding plate has an opening. Two lower clamping blocks are fixedly connected to the top of the sliding plate. Multiple vertical rods are fixedly connected to the bottom of the sliding plate. Limiting rings are fixedly connected to the bottom ends of the vertical rods. Springs are sleeved on the outer walls of the vertical rods. A sliding plate is slidably sleeved between the multiple vertical rods. A connecting plate is fixedly connected to one end of the sliding plate. The top end of the connecting plate passes through the sliding plate and slidably inserts into it. An upper clamping block is fixedly connected to the top end of the connecting plate. The upper clamping block and the lower clamping block are joined together.
[0007] Furthermore, two threaded rods are rotatably inserted between the inner walls of the two sides of the cross frame, and the sliding plate is threadedly connected to the threaded rods.
[0008] Furthermore, one end of the threaded rod is keyed to a sprocket, and a chain is driven between the two sprockets.
[0009] Furthermore, a motor is fixedly connected to one side of the outer wall of the cross frame, and the output end of the motor is fixedly connected to one end of one of the threaded rods.
[0010] Furthermore, a base plate is fixedly connected to the bottom outer wall of the vertical frame, and two support plates are fixedly connected to the top of the base plate. The top of the support plates is fixedly connected to the bottom of the horizontal frame.
[0011] Furthermore, rubber pads are adhered to the top of the lower clamping block and the bottom of the upper clamping block, and anti-slip grooves are provided on the rubber pads.
[0012] Furthermore, a limiting block is fixedly connected to one end of the top of the sliding plate, and the limiting block is located at one end of one of the lower clamping blocks.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. By placing the connector and wire harness on the lower clamping block, and then using the elasticity of the spring to reset the slide plate and connecting plate, the upper clamping block and the lower clamping block are brought together, thereby limiting and fixing the wire harness and connector to prevent them from shifting during movement.
[0015] 2. Driven by the motor and the chain, the threaded rod rotates, causing the sliding plate to move along the guide rod, which in turn moves the wire harness and connector, moving them below the crimping head for crimping. This is convenient and quick, avoiding the need to use your hands and preventing hands from being crushed during wire harness crimping. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figures 1-6 A wire harness crimping mechanism for preventing hand crushing includes a vertical frame 1. The top inner wall and bottom inner wall of the vertical frame 1 are both fixed with hydraulic cylinders 2 by bolts. One end of the hydraulic rod of the hydraulic cylinder 2 is fixed with a crimping connector 3 by bolts. Under the drive of the hydraulic cylinder 2, the crimping connector 3 moves, thereby causing the two crimping connectors 3 to converge towards the middle, and thus crimping the wire harness and the crimping connector 3 together.
[0025] A horizontal frame 4 is welded between the inner walls of the two sides of the vertical frame 1. Multiple guide rods 5 are welded between the inner walls of the two sides of the horizontal frame 4. A sliding plate 6 is slidably sleeved between the multiple guide rods 5. The sliding plate 6 has a through-hole 13. Two lower clamping blocks 14 are fixed to the top of the sliding plate 6 by bolts. Multiple vertical rods 7 are welded to the bottom of the sliding plate 6. A limit ring 8 is welded to the bottom end of the vertical rod 7. A spring 9 is sleeved on the outer wall of the vertical rod 7. A sliding plate 10 is slidably sleeved between the multiple vertical rods 7. The sliding plate 10 can be a metal plate. A connecting plate 11 is welded to one end of the sliding plate 10. The top end of the connecting plate 11 passes through the sliding plate 6 and is slidably inserted into the sliding plate 6. An upper clamping block 12 is welded to the top end of the connecting plate 11. The upper clamping block 12 and the lower clamping block 14 are joined together. Under the elastic action of the spring 9, the sliding plate 10 and the connecting plate 11 are reset, so that the upper clamping block 12 and the lower clamping block 14 are joined together, thereby limiting and fixing the wire harness and connector. The upper clamping block 12 and the lower clamping block 14 are lightweight block structures.
[0026] Two threaded rods 15 are rotatably inserted between the inner walls of both sides of the horizontal frame 4. The sliding plate 6 is threadedly connected to the threaded rods 15. One end of the threaded rod 15 is keyed to a sprocket 16. A chain 17 is driven between the two sprockets 16. A motor 18 is bolted to one side of the outer wall of the horizontal frame 4. The output end of the motor 18 is fixedly connected to one end of one of the threaded rods 15. Driven by the motor 18 and driven by the chain 17, the threaded rod 15 rotates, causing the sliding plate 6 to move along the guide rod 5, thereby moving the wire harness and connector, and then moving the wire harness and connector below the crimp connector 3. A base plate 19 is welded to the bottom outer wall of the vertical frame 1. Two support plates 20 are welded to the top of the base plate 19. The top of the support plates 20 is fixedly connected to the bottom of the horizontal frame 4, thereby providing stable support for the horizontal frame 4. Rubber pads 21 are glued to the top of the lower clamping block 14 and the bottom of the upper clamping block 12. Anti-slip grooves 22 are provided on the rubber pads 21, thereby strengthening the friction between the wire harness and connector and the upper clamping block 12 and the lower clamping block 14, and improving the stability of the wire harness and connector. A limit block 23 is welded to one end of the top of the sliding plate 6. The limit block 23 is located at one end of one of the lower clamping blocks 14, thereby limiting the end where the connector is placed.
[0027] The working principle of this embodiment is as follows: In use, firstly, the connector is put on one end of the wire harness. Then, the sliding plate 10 is pushed upward to move the connecting plate 11 upward, thereby driving the upper clamping block 12 upward, which in turn separates the upper clamping block 12 from the lower clamping block 14. Next, the connector and wire harness are placed on the lower clamping block 14, and one end of the connector is pressed against the limiting block 23. Then, the sliding plate 10 is released, and the sliding plate 10 and the connecting plate 11 are reset under the elastic action of the spring 9, so that the upper clamping block 12 and the lower clamping block 14 are put together, thereby fixing the wire harness and the connector.
[0028] Next, the motor 18 is started. Driven by the motor 18 and the chain 17, the threaded rod 15 is rotated, causing the sliding plate 6 to move along the guide rod 5, thereby moving the wire harness and connector, and then moving the wire harness and connector between the two crimping joints 3. Then, the hydraulic cylinder 2 is started. Driven by the hydraulic cylinder 2, the crimping joints 3 are moved, causing the two crimping joints 3 to converge in the middle, and then crimping the wire harness and the crimping joints 3 together.
