Description

Technical Field

[0001] This utility model relates to the field of wire harness terminal crimping technology, specifically a wire harness terminal crimping machine. Background Technology

[0002] In modern industrial production, wire harness terminal crimping is a crucial process, especially in the fields of electronics, electrical engineering, communications, and automobiles, where it plays a pivotal role. Wire harness terminal crimping refers to the process of connecting wires or cables to terminals using mechanical pressure.

[0003] For example, Chinese utility model patent CN222508320U discloses a wire harness terminal crimping machine, which relates to the field of crimping machine technology. It includes a base plate, a mounting block fixedly connected to the top left of the base plate, a coiling tube rotatably connected inside the mounting block, a second motor fixedly connected to the left end of the mounting block, and the output end of the second motor fixedly connected to the coiling tube. A mounting frame is fixedly connected to the top of the mounting block, a second telescopic rod is fixedly connected to the top of the mounting frame, and a pressure head is fixedly connected to the bottom end of the second telescopic rod. A displacement component is provided on the top right of the base plate, a first telescopic rod is fixedly connected to the output end of the displacement component, a clamping component is fixedly connected to the top of the first telescopic rod, and a wire core sleeve is provided on the top of the mounting block. This utility model uses the displacement component to move the wire towards the mounting block, inserting the wire into the coiling tube and coiling it. The second motor drives the coiling tube to rotate, causing the wires inside the coiling tube to be twisted together, aiding in wire concentration and improving work efficiency.

[0004] However, the existing wire harness terminal crimping machine has its crimp head fixedly connected to the bottom of the second telescopic rod, and its lower clamp plate fixedly connected to the top of the mounting base. This makes it inconvenient to replace the crimping head according to the thickness of the wire harness and the shape of the crimping, thus reducing the flexibility of the device.

[0005] Therefore, we propose a wire harness terminal crimping machine to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please see Figure 1-3 This is the first embodiment of the present utility model, which provides a technical solution: a wire harness terminal crimping machine, including a fixed frame 1 and a fixed plate 17. A cylinder 2 is fixedly installed on the top surface of the fixed frame 1. A connecting rod 3 is fixedly connected to the output end of the piston rod of the cylinder 2. A mounting seat 4 is fixedly installed at the bottom end of the connecting rod 3. A mounting groove 41 is opened on the bottom surface of the mounting seat 4. A through hole 42 is opened on one side of the mounting seat 4. A crimping head 5 is snapped into the mounting groove 41. A limiting hole 51 is opened on one side of the crimping head 5. A limiting mounting rod 7 is movably connected to the smooth rod of the through hole 42 and the limiting hole 51. A limiting round block 6 is fixedly connected to the end of the limiting mounting rod 7. A limiting nut 8 is threadedly connected to the threaded part of the limiting mounting rod 7. A fixing seat 12 is fixedly connected to the bottom surface of the fixing frame 1. A second mounting groove 121 is opened on the top surface of the fixing seat 12. A second through hole 122 is opened on one side of the fixing seat 12. A placement seat 13 is snapped into the second mounting groove 121. A second limiting hole 131 is opened on one side of the placement seat 13. A second limiting mounting rod 15 is movably connected to the smooth rod of the second limiting mounting rod 15 in the second through hole 122 and the second limiting hole 131. A second limiting round block 14 is fixedly connected to the end of the second limiting mounting rod 15. A second limiting nut 16 is threadedly connected to the threaded part of the second limiting mounting rod 15. A fixing plate 17 is connected to the fixing seat 12 by multiple bolts 18. A connecting terminal positioning rod 19 is fixedly connected to the top surface of the fixing plate 17. It is used to position and limit the connection when the hole and groove on the connecting terminal are snapped into the connecting terminal positioning rod 19 after the wire harness is inserted into the connecting terminal.

[0018] Example 2: Please see Figure 1-3 This is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. The through hole 42 and the mounting groove 41 are internally connected. One side of the limiting block 6 contacts one side of the mounting base 4, and one side of the limiting nut 8 contacts one side of the mounting base 4, so as to effectively limit the movement.

[0019] The through hole 122 and the mounting groove 121 are internally connected. One side of the limiting block 14 contacts one side of the fixing seat 12, and one side of the limiting nut 16 contacts one side of the fixing seat 12, which can effectively limit the movement.

[0020] The mounting base 4 is fixedly connected to the connecting blocks 9 on both sides, and the top surface of the connecting blocks 9 is fixedly connected to the limiting slide rod 10.

[0021] Limiting through holes 11 are respectively opened at both ends of the top of the fixed frame 1. The limiting slide rod 10 is slidably connected to the limiting through hole 11. When the mounting base 4 and the pressure head 5 are raised and lowered, the limiting slide rod 10 slides in the limiting through hole 11, thereby improving the stability of the raising and lowering of the mounting base 4 and the pressure head 5.

[0022] The top surface of the placement base 13 has a placement groove 132 for placing the wire harness.

[0023] Please see Figure 1-3In use, the wire harness is inserted into the connecting terminal, and the slot on the connecting terminal is engaged with the connecting terminal positioning rod 19. The wire harness is then placed on the placement slot 132 of the placement base 13. The cylinder 2 is connected to an external power source. Starting the cylinder 2 moves the mounting base 4 and the pressure head 5 downwards. The pressure head 5 acts on the connecting terminal, pressing the connecting terminal and the wire harness together. When the pressure head 5 needs to be replaced, the limit nut 8 can be unscrewed from the thread of the limit mounting rod 7. The limit mounting rod 7 can be pulled out of the limit hole 51 and through hole 42 by manually turning the limit block 6, thus releasing the limit on the pressure head 5. The pressure head 5 can then be disassembled and replaced. When the placement base 13 needs to be replaced, the limit nut 16 can be unscrewed from the thread of the limit mounting rod 15. By manually moving the limiting block 14, the limiting mounting rod 15 can be pulled out of the limiting hole 131 and through hole 122, thus releasing the limitation on the placement seat 13. The placement seat 13 can be disassembled and replaced. When the specification of the connecting terminal positioning rod 19 needs to be changed, the bolt 18 can be unscrewed, the fixing plate 17 can be removed, and the fixing plate 17 with the corresponding specification connecting terminal positioning rod 19 can be replaced. This facilitates the disassembly and replacement of the pressure head 5 and the placement seat 13. The pressure head 5 and the placement seat 13 can be disassembled and replaced according to the thickness of the wire harness and the shape of the crimping. It is convenient to position and limit the placed connecting terminal through the connecting terminal positioning rod 19, which is convenient for crimping. It is also convenient to disassemble and replace according to the size of the hole and groove on the crimped terminal, improving the flexibility of the device.
