Description

Technical Field

[0001] This utility model belongs to the field of soldering fixture technology, specifically relating to an auxiliary soldering fixture assembly for wire harness terminals. Background Technology

[0002] The wire harness terminal auxiliary soldering fixture assembly is a special tooling fixture combination used to assist in completing the soldering operation of wire harness terminals. Its main functions are to improve soldering efficiency, ensure the stability of soldering quality, and reduce the difficulty of manual operation. It is widely used in manufacturing fields such as electronics, automobiles, and home appliances that require soldering of wire harness terminals.

[0003] Chinese patent discloses an auxiliary soldering fixture for wire harness terminals (publication number CN220533176U). This patented technology uses a combination of a feeding roller, a micro motor, and an outer ring conveyor belt to drive the feeding roller to rotate inside the cover plate. The bottom of the feeding roller contacts the wire harness terminal. As the feeding roller rotates, it quickly guides the welding end of the wire harness terminal to the welding point of the auxiliary fixture for welding. However, it has poor adaptability and is difficult to accommodate terminals of different sizes. It is prone to jamming. For example, it is difficult for terminals that are too thick to pass through, and terminals that are too thin are prone to insufficient driving force.

[0004] Therefore, the purpose of this utility model is to provide an auxiliary soldering fixture assembly for wire harness terminals. Utility Model Content

[0023] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figure 1 As shown, a wire harness terminal auxiliary soldering fixture assembly includes an auxiliary fixture 1. A pair of translation mechanisms are correspondingly arranged inside the auxiliary fixture 1. A fixing sleeve 6 is connected to the outer side of the translation mechanism. A U-shaped frame 4 is connected to the inner side of the pair of fixing sleeves 6. Nine concave clamps 16 are horizontally connected to the bottom surface of the inner wall of the U-shaped frame 4. Three positioning holes 15 are opened on both side walls of the U-shaped frame 4. A positioning mechanism is arranged on the inner side of the U-shaped frame 4 near the positioning holes 15. A lifting plate 3 is connected to the bottom of the pair of positioning mechanisms.

[0025] The lifting plate 3 has nine first through holes 11 horizontally opened inside. The first through holes 11 are equipped with elastic mechanisms. The bottom of the elastic mechanisms is connected to concave clamps 13. The position of the concave clamps 13 corresponds to the position of the concave clamps 16.

[0026] like Figure 3 and Figure 4As shown, the positioning mechanism includes a U-shaped plate 10. The bottom of the U-shaped plate 10 is fixedly connected to the lifting plate 3. A second through hole 20 is provided on both sides of the U-shaped plate 10. A positioning rod 9 is connected through the interior of the pair of second through holes 20. A pull plate 21 is connected to one end of the positioning rod 9. A fixing ring 18 is fixedly connected to the outside of the positioning rod 9 and inside the U-shaped plate 10. A second spring 19 is sleeved on the outside of the positioning rod 9 and to the right of the fixing ring 18. One end of the second spring 19 is fixedly connected to the fixing ring 18, and the other end of the second spring 19 is fixedly connected to the U-shaped plate 10. When the pull plate 21 is released, the elastic recovery effect of the second spring 19 is used to easily drive the positioning rod 9 to be inserted into the interior of the U-shaped frame 4, thereby fixing the height of the lifting plate 3.

[0027] like Figure 3 and Figure 4 As shown, the diameter of the second through hole 20 is the same as the diameter of the positioning hole 15, and the other end of the positioning rod 9 passes through the interior of the positioning hole 15. By adjusting the diameter of the second through hole 20 and the height of the positioning hole 15, the other end of the positioning rod 9 is then inserted into the interior of the positioning hole 15.

[0028] like Figure 3 As shown, the elastic mechanism includes a first spring 14, the top end of the first spring 14 is fixedly connected to the lifting plate 3, the end of the first spring 14 is fixedly connected to the concave clamping plate 13, and a movable rod 12 is connected inside the first spring 14. The end of the movable rod 12 is fixedly connected to the concave clamping plate 13. The top end of the movable rod 12 passes through the interior of the first through hole 11. When the concave clamping plate 13 is fastened to the outside of the wire harness terminal, it compresses the second spring 19. The rebound force generated when the second spring 19 is compressed will be converted into the clamping force of the concave clamping plate 13 on the terminal.

[0029] like Figure 1 and Figure 2 As shown, the translation mechanism includes a servo motor 5. One end of the output shaft of the servo motor 5 is connected to a reciprocating lead screw 2. One end of the reciprocating lead screw 2 is rotatably connected to a bearing seat 8. The bearing seat 8 and the bottom of the servo motor 5 are both fixedly connected to the auxiliary fixture 1. A ball nut assembly 7 is connected to the outside of the reciprocating lead screw 2. The outside of the ball nut assembly 7 is fixedly connected to a fixing sleeve 6. When the servo motor 5 is turned on, the reciprocating lead screw 2 is rotated, which in turn drives the ball nut assembly 7, the fixing sleeve 6, and the U-shaped frame 4 to move left and right. This facilitates the movement of the U-shaped frame 4 to the bottom of the soldering equipment, achieving a traction effect and preventing the wire harness terminals, which are relatively soft, from easily bending and failing to pass through the auxiliary fixture.

[0030] like Figure 3 and Figure 5As shown, the top of the concave clamp 16 is provided with a pair of first rounded corners 17, and the two sides of the concave clamp 13 are provided with a pair of second rounded corners 22. Compared with the right-angled edge, the arc surface can disperse the clamping force and avoid physical damage caused by local stress concentration.

[0031] The working principle of this utility model is as follows: After placing the wire harness terminal on the top of the concave clamp 16, first adjust the fixed height of the lifting plate 3 according to the thickness of the terminal, and then fix the height of the lifting plate 3 by the positioning rods 9 on both sides. At this time, the concave clamp 13 is fastened to the outside of the wire harness terminal, and the second spring 19 is compressed at the same time. The rebound force generated when the second spring 19 is compressed will be converted into the clamping force of the concave clamp 13 on the terminal. First, the coarse adjustment is achieved by adjusting the height of the lifting plate 3, and then the fine adjustment is achieved by combining the spring force. This can cover a certain range of size differences, which is conducive to achieving compatibility with terminals of different sizes.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
