Abstract
Description
Technical Field
[0001] This utility model relates to the field of terminal crimping technology, specifically to a terminal crimping device for wire harness processing. Background Technology
[0002] As a core connection component in electrical systems, wire harnesses are widely used in the automotive, aerospace, industrial equipment, and consumer electronics fields. Their processing quality directly affects the stability and safety of equipment signal transmission. Terminal crimping is a key step in wire harness manufacturing, which requires the metal terminals and wires to be mechanically fastened and electrically connected through plastic deformation.
[0003] A search of Chinese patent CN220774953U reveals a terminal crimping device for automotive wiring harness processing. The device includes a terminal block machine body, a hydraulic cylinder fixedly connected to the top of the machine body, and a receiving plate fixedly connected to the bottom of the machine body. The piston end of the hydraulic cylinder penetrates the machine body and is fixedly connected to a crimping plug. A crimping housing is located below the crimping plug, and an assembly pressure head is connected to the bottom of the crimping housing via an assembly plate. This invention utilizes an adjusting bevel gear to rotate an adjusting screw, which in turn moves an adjusting sleeve along the direction of the adjusting screw. Simultaneously, the adjusting sleeve causes the adjusting insert to engage or disengage with a movable insertion hole on a moving support block, facilitating the replacement of the crimping mold after disassembly and thus improving the performance.
[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. In the process of crimping the terminals of the wire harness, it is necessary to manually pick up the wire harness one by one for crimping, which results in low processing efficiency of the wire harness and makes it inconvenient to support the terminals. The terminals are also prone to misalignment during the crimping process. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a terminal crimping device for wire harness processing.
[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0007] An embodiment of this utility model provides a terminal crimping device for wire harness processing, including a machine body, a hydraulic cylinder provided on the machine body, a crimping block fixedly installed on the telescopic end of the hydraulic cylinder, a support platform fixedly installed on the machine body, a crimping mechanism provided on the machine body, the crimping mechanism including a drive assembly provided on the machine body, a mounting frame provided on the drive assembly, a snap-fit assembly provided on the mounting frame, a mounting plate slidably installed on the mounting frame, and a mold fixedly installed on the mounting plate;
[0008] The mounting plate is provided with a support mechanism, which includes multiple wire clamps fixedly mounted on the mounting plate, and the mounting plate is provided with a clamping assembly.
[0009] Furthermore, the drive assembly includes a drive motor mounted on the machine body, and a reciprocating lead screw is fixedly mounted on the output end of the drive motor.
[0010] Furthermore, a threaded block is threaded onto the reciprocating lead screw, and a support frame that is fixed to the mounting bracket is fixed onto the threaded block.
[0011] Furthermore, the snap-fit assembly includes two circular shells fixedly mounted on the mounting bracket, with a first spring connected to the inner wall of each circular shell, and a snap-fit block slidably connected to the end of the first spring.
[0012] Furthermore, the mounting plate has two locking holes that engage with the locking block.
[0013] Furthermore, the clamping assembly includes a fixed housing that is fixedly mounted on the mounting plate, and the fixed housing has multiple slots.
[0014] Furthermore, a second spring is connected to the inner wall of each slot, and the end of the second spring is connected to a movable block that is slidably connected to the slot.
[0015] The above-described solution of this utility model has at least the following beneficial effects:
[0016] 1. In this utility model, by moving the mounting plate onto the mounting frame and fixing the mounting plate by engaging the locking blocks with the locking holes, multiple wire harnesses with terminals are placed on the mold, and the drive motor is controlled to run. After each pair of terminals is crimped, the mold is controlled to move, so that the mold drives multiple wire harnesses to move, and multiple terminals are crimped in sequence, thereby improving the efficiency of the crimping work and achieving a high degree of automation.
[0017] 2. In this utility model, by attaching the wire harness to the wire clamp, the terminal on the wire harness is moved between the mold and the movable block. The movable block is used to clamp and limit the terminal. When the crimping block crimps the terminal, the crimping block squeezes the movable block into the inner side of the fixed shell, thereby preventing the terminal from being misaligned during the crimping process.

Detailed Implementation
[0025] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
[0026] like Figures 1 to 5 As shown, an embodiment of this utility model provides a terminal crimping device for wire harness processing, including a body 1, a hydraulic cylinder 2 fixedly mounted on the body 1, a crimping block 3 fixedly mounted on the telescopic end of the hydraulic cylinder 2, a support platform 4 fixedly mounted on the body 1, a crimping mechanism mounted on the body 1, the crimping mechanism including a drive assembly mounted on the body 1, a mounting frame 9 mounted on the drive assembly, a snap-fit assembly mounted on the mounting frame 9, a mounting plate 13 slidably mounted on the mounting frame 9, and a mold 15 fixedly mounted on the mounting plate 13. The components include a drive motor 5 fixedly mounted on the body 1, a reciprocating lead screw 6 fixedly mounted on the output end of the drive motor 5, a threaded block 7 threadedly mounted on the reciprocating lead screw 6, a support frame 8 fixedly mounted on the threaded block 7 and fixed to the mounting frame 9, and a snap-fit assembly including two round shells 10 fixedly mounted on the mounting frame 9, a first spring 11 connected to the inner wall of the round shell 10, a snap-fit block 12 slidably connected to the end of the first spring 11 and the mounting plate 13 having two snap-fit holes 14 for snap-fitting with the snap-fit block 12.
[0027] In this embodiment of the invention, the first spring 11 supports the locking block 12 using its own elastic force. The operator moves the mounting plate 13 onto the mounting frame 9, and uses the locking block 12 to engage with the locking hole 14 to fix the mounting plate 13. Multiple wire harnesses with terminals are placed on the mold 15, and the drive motor 5 is controlled to run. The output end of the drive motor 5 drives the reciprocating screw 6 to rotate, and the reciprocating screw 6 drives the threaded block 7 to move using the thread action. The threaded block 7 drives the mounting frame 9 to move through the support frame 8, and the mounting frame 9 drives the mold 15 to move through the mounting plate 13. After each pair of terminals is crimped, the mold 15 is controlled to move, so that the mold 15 drives multiple wire harnesses to move, and multiple terminals are crimped in sequence, thereby improving the efficiency of the crimping work and achieving a high degree of automation.
[0028] Figures 1 to 5 As shown, a support mechanism is provided on the mounting plate 13. The support mechanism includes multiple wire clamps 16 fixedly installed on the mounting plate 13. A clamping assembly is provided on the mounting plate 13. The clamping assembly includes a fixed shell 17 fixedly installed on the mounting plate 13. Multiple slots 18 are provided on the fixed shell 17. A second spring 19 is connected to the inner wall of each slot 18. The end of the second spring 19 is connected to a movable block 20 that is slidably connected to the slot 18.
[0029] In this embodiment of the utility model, the operator moves the terminal on the wire harness to between the mold 15 and the movable block 20 by snapping the wire harness onto the wire clamp 16. The movable block 20 is used to clamp and limit the terminal. When the crimping block 3 crimps the terminal, the crimping block 3 presses the movable block 20 into the inner side of the fixed shell 17, thereby preventing the terminal from being misaligned during the crimping process.
[0030] When the pressing block 3 separates from the movable block 20, the second spring 19 can use its own elastic force to move the movable block 20 out of the inside of the slot 18.
[0031] Working principle: The operator attaches the wire harness to the clamp 16, moves the terminals on the wire harness between the mold 15 and the movable block 20, and uses the movable block 20 to clamp and limit the terminals. The operator moves the mounting plate 13 to the mounting frame 9, and uses the locking block 12 and the locking hole 14 to lock the mounting plate 13. Multiple wire harnesses with terminals are placed on the mold 15, and the drive motor 5 is controlled to run. After each terminal is crimped, the mold 15 is controlled to move, so that the mold 15 drives multiple wire harnesses to move, and multiple terminals are crimped in sequence. When the crimping block 3 crimps the terminal, the crimping block 3 squeezes the movable block 20 into the inside of the fixed shell 17.
[0032] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
