Abstract
Description
Technical Field
[0001] This utility model relates to the field of guiding mechanism technology, and in particular to a guiding mechanism for automotive wiring harness terminal crimping equipment. Background Technology
[0002] Automotive wiring harness terminal crimping equipment is a specialized piece of equipment used in the automotive wiring harness production process. It is used to connect wire terminals to wires, ensuring the reliability and electrical performance of the connection. In use, the wiring harness to which the terminals need to be crimped is inserted into the crimping equipment, and the crimping equipment crimps the terminals to one end of the wiring harness, thereby achieving terminal crimping.
[0003] Existing crimping equipment mainly uses a crimping machine for crimping. During crimping, the terminal chain is inserted into the guide mechanism inside the crimping machine, and then the feeding mechanism pushes the terminal chain one by one to the position of the cutting mechanism. The wire harness is inserted into the terminal inside the cutting mechanism, and the terminal is crimped to one end of the wire harness by the cutting and squeezing of the cutting mechanism.
[0004] When using existing crimping equipment, different sizes of terminals are required depending on the specifications of the crimped wire harness. Before crimping, the terminals are in the form of terminal chains. However, the existing guiding mechanism cannot be adjusted according to the different specifications of the terminal chains, so it is not possible to properly tighten and fix the chains. This causes the wire harness to deviate during terminal transport, affecting the crimping process. Utility Model Content

[0016] (III) Beneficial Effects
[0017] This utility model provides a guiding mechanism for automotive wiring harness terminal crimping equipment. It has the following beneficial effects:
[0018] 1. Rotate the threaded rod to move the L-shaped plate, thereby opening up the space inside the fixed frame to facilitate the insertion of the terminal chain. When the terminal chain is released from the abutment plate, the inclined surface of the abutment plate allows the terminal chain to be smoothly inserted into the fixed frame. After the terminal chain is inserted, rotate the threaded rod in the opposite direction, thereby causing the L-shaped plate to slide inside the fixed frame. This further causes the abutment plate to press one end of the terminal chain, thus preventing the terminal chain from shaking inside the fixed frame. Additionally, the L-shaped plate can press down on the top of the terminal chain to prevent it from jumping up during transport, which could lead to unstable transport.

The movable block pulls the pressing block through the connecting rod, so that the pressing block separates from the teeth on the upper surface of the substrate, thereby releasing the lock. Then, through the cooperation between the fixed plate and the upper surface of the substrate, the fixed frame is driven to slide on the upper surface of the substrate, which facilitates the docking of the terminal chain and the subsequent processing shearing mechanism.

Detailed Implementation
[0026] 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.
[0027] Example 1
[0028] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a guide mechanism for an automotive wiring harness terminal crimping device, including a base plate 3. A fixing frame 1 is provided on the upper surface of the base plate 3. A terminal chain belt 5 is provided inside the fixing frame 1. A limiting component 4 is provided inside the fixing frame 1. A locking component 2 is provided between the fixing frame 1 and the base plate 3. The limiting component 4 includes a threaded rod 403 movably connected inside the fixing frame 1. An L-shaped plate 401 is engaged with the outer surface of the threaded rod 403. A plurality of insert rods 402 are inserted inside the L-shaped plate 401. An abutment plate 405 is fixedly connected to one end of the insert rod 402 near the threaded rod 403. A plurality of compression springs 406 are fixedly connected between the abutment plate 405 and the L-shaped plate 401.
[0029] Specifically, a limiting block 404 is fixedly connected to the upper surface of the abutment plate 405, a sliding groove that cooperates with the limiting block 404 is opened on the inner top surface of the L-shaped plate 401, a sliding groove is opened inside the fixing frame 1, a slider that cooperates with the sliding groove is fixedly connected to the bottom surface of the L-shaped plate 401, and an inclined surface for the terminal chain belt 5 is provided on the outer surface of the abutment plate 405.
[0030] Furthermore, rotating the threaded rod 403 moves the L-shaped plate 401, thereby opening the space inside the fixed frame 1 to facilitate the insertion of the terminal chain 5. Then, the terminal chain 5 to be crimped is inserted into the fixed frame 1. When the terminal chain 5 releases the abutment plate 405, the inclined surface of the outer surface of the abutment plate 405 allows the terminal chain 5 to be smoothly inserted into the fixed frame 1. The abutment plate 405 is inserted into the L-shaped plate 401 by the action of the insertion rod 402 and the compression spring 406. After inserting the terminal chain 5, rotating the threaded rod 403 in the opposite direction causes the L-shaped plate 401 to slide inside the fixed frame 1, further causing the abutment plate 405 to press one end of the terminal chain 5, thereby preventing the terminal chain 5 from shaking inside the fixed frame 1. Furthermore, the L-shaped plate 401 allows the terminal chain 5 to be pressed down on the top of the terminal chain 5 during the conveying process, preventing the terminal chain 5 from jumping up and causing unstable conveying.
[0031] Example 2
[0032] Reference Figure 1 , Figure 2 and Figure 4This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The locking component 2 includes a fixing plate 208 fixedly connected to the lower surface of the fixing frame 1. The fixing plate 208 is slidably connected to the outer surface of the base plate 3. Two fixing blocks 201 are fixedly connected to the side of the fixing frame 1. Two connecting rods 203 are interspersed inside the fixing frame 1. A pressing block 207 is fixedly connected to the end of the connecting rod 203 away from the fixing block 201. A movable block 202 is fixedly connected to the end of the connecting rod 203 away from the pressing block 207. A plug-in rod 204 that cooperates with the movable block 202 is interspersed inside the fixing block 201.
[0033] Specifically, the upper surface of the substrate 3 is provided with a rectangular protrusion. A limiting groove is provided on the side of the rectangular protrusion on the upper surface of the substrate 3 near the fixing plate 208. The outer surface of the fixing plate 208 is provided with a limiting protrusion that cooperates with the limiting groove. The side of the rectangular protrusion on the upper surface of the substrate 3 near the extrusion block 207 is provided with teeth that cooperate with the extrusion block 207. The outer surface of the movable block 202 is provided with a insertion hole that cooperates with the insertion rod 204. The end of the insertion rod 204 away from the movable block 202 passes through the fixing block 201 and is fixedly connected to a pull block 206. A tension spring 205 is fixedly connected between the pull block 206 and the fixing block 201.
[0034] Furthermore, by pulling the plug rod 204 through the pull block 206, the plug rod 204 is pulled out of the movable block 202, thereby releasing the movable block 202 from its limit. The movable block 202 then pulls the pressing block 207 through the connecting rod 203, causing the pressing block 207 to separate from the teeth on the upper surface of the substrate 3, thus releasing the lock. Then, through the cooperation between the fixing plate 208 and the upper surface of the substrate 3, the fixing frame 1 is driven to slide on the upper surface of the substrate 3. The pressing block 207 is made of soft rubber, which allows it to disengage well from the teeth on the upper surface of the substrate 3.
[0035] Working Principle: When crimping automotive wiring harness terminals, rotating the threaded rod 403 moves the L-shaped plate 401, opening the space inside the fixed frame 1 to facilitate the insertion of the terminal chain 5. The terminal chain 5 to be crimped is then inserted into the fixed frame 1. When the terminal chain 5 releases the abutment plate 405, the inclined surface of the abutment plate 405 allows it to smoothly insert into the fixed frame 1. The abutment plate 405, through the action of the insertion rod 402 and the compression spring 406, inserts into the L-shaped plate 401. After inserting the terminal chain 5, rotating the threaded rod 403 in the opposite direction causes the L-shaped plate 401 to slide inside the fixed frame 1, further pressing one end of the terminal chain 5 against the abutment plate 405. This prevents the terminal chain 5 from shaking inside the fixed frame 1. Furthermore, the L-shaped plate 401, during transport, presses down on the top of the terminal chain 5, preventing it from shifting during transport. The jump caused by the device was unstable. After inserting and fixing the terminal chain 5, the fixing frame 1 and the shearing mechanism were connected according to the specifications of the terminal chain 5. The plug rod 204 was pulled by the pull block 206, so that the plug rod 204 was pulled out of the movable block 202, so that the movable block 202 was released from its limit. The movable block 202 pulled the pressing block 207 through the connecting rod 203, so that the pressing block 207 was separated from the teeth on the upper surface of the substrate 3, thereby releasing the lock. Then, the fixing plate 208 cooperated with the upper surface of the substrate 3 to drive the fixing frame 1 to slide on the upper surface of the substrate 3, so as to facilitate the connection between the terminal chain 5 and the shearing mechanism. After the connection was completed, the pressing block 207 was inserted through the movable block 202 and the connecting rod 203, so that the pressing block 207 abutted against the teeth on the upper surface of the substrate 3. The movable block 202 was locked by the plug rod 204 inserted inside the fixing block 201, thereby locking the fixing frame 1 and finally realizing the adjustment of the guide mechanism.
