[0027] 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.

[0028] This utility model provides a technical solution: such as Figure 1 and Figure 2 As shown, in this embodiment, a terminal crimping fixture includes a base 1, a bracket 11 fixedly installed at the rear end of the base 1, and anti-slip pads 12 are provided on the edges of the bottom side of the base 1. The anti-slip pads 12 can improve the stability of the fixture. A crimping structure 2 is installed at the front end of the bracket 11, and a mounting seat 13 is bolted to the middle of the end face of the base 1. Crimping positioning structures 3 are installed on both sides of the mounting seat 13.

[0029] like Figure 1 and Figure 2 As shown, the pressing structure 2 includes a cylinder 21, which is mounted on the upper end of the bracket 11. The output end of the cylinder 21 is bolted to a connecting plate 22. Both sides of the bottom of the connecting plate 22 are bolted to a pressing die 24, which corresponds to the pressing groove 32. Guide rods 23 are fixedly connected to both ends of the bottom side of the bracket 11. The outer wall of the guide rod 23 is slidably connected to the inner wall of the through hole at the rear end of the connecting plate 22. The guide rods 23 can improve the stability of the pressing die and make the pressing more stable. The pressing die 24 is bolted to the connecting plate 22, and the matching pressing die 24 can be replaced according to the size of the adjusted pressing groove 32. In addition, two sets of pressing dies 24 and pressing grooves 32 are set to improve the pressing efficiency.

[0030] like Figure 3 and Figure 4 As shown, the crimping and positioning structure 3 includes a pressure plate 31. A crimping groove 32 is formed in the middle of the pressure plate 31, and an installation groove 33 is formed below the pressure plate 31. Receiving grooves 332 are formed on the side walls of the pressure plate 31 at both ends of the crimping groove 32. Through grooves 331 are formed between the receiving grooves 332 and the installation groove 33. The inner wall of the through groove 331 is slidably connected to the outer wall of the movable plate 36. The receiving grooves 332 are used to receive the installation plate 37. A bidirectional screw 34 is provided in the middle of the installation groove 33 via a bearing. A knob is provided at one end of each bidirectional screw 34, and the knobs are all located on the outside of the pressure plate 31. Limiting rods 35 are fixedly connected to both ends of the installation groove 33. Movable plates 36 are fitted onto the outer walls of both sides of the bidirectional screw 34 and the limiting rods 35. The top of the movable plates 36 is fixedly... A mounting plate 37 is fixedly connected to the mounting plate 37, and a fixing plate 38 is bolted to one end of the mounting plate 37. A positioning plate 39 is fixedly connected to the outside of the fixing plate 38. The two positioning plates 39 are located at both ends of the crimping groove 32. By setting the positioning plates 39 at both ends of the crimping groove 32 of the pressure plate 31, the positioning plates 39 can restrict the lateral movement of the terminal and wire harness during the crimping process, ensuring that they are always in the correct position of the crimping groove 32, avoiding crimping deviation or crimping, thereby reducing the time for manual adjustment. In addition, the positioning plates 39 can be adjusted according to the size of the wire harness or terminal, so that they can be adapted to terminals and wire harnesses of different sizes, improving the versatility of the fixture. And the adjustment can be made by simply turning the knob, which is convenient and reduces the time for adjustment and positioning.

[0031] This utility model provides a terminal crimping fixture, the specific working principle of which is as follows: the terminal and wire harness are placed in the corresponding crimping groove 32, and the external knob is rotated according to its size, which drives the bidirectional screw 34 to rotate, so that the movable plates 36 on both sides move towards each other until the positioning plates 39 on both sides position the placed terminal and wire harness. The crimping die 24 is changed according to the distance between the two positioning plates 39. During crimping, the cylinder 21 is activated so that the connecting plate 22 drives the crimping die 24 to crimp in the crimping groove 32, crimping the terminal and wire harness together. At the same time as the crimping die 24 moves down, the connecting plate 22 slides on the guide rod 23.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
