The driving mechanism 11 includes a slideway 111 evenly distributed and symmetrically opened on the base 1, a slider 112 slidably arranged on the slideway 111, and a driving member 113 arranged on the top plate 3. The driving member 113 includes a slideway 1131 evenly distributed and symmetrically opened on the bottom surface of the top plate 3. , a slider 1132 slidingly arranged on the slide 1131, a motor 1133 fixedly installed on the side of the top plate 3 and evenly distributed and symmetrical, and a screw rod 1134 rotatably arranged in the slide 1131, the bottom end of the limit rod 10 is fixedly installed with the slider 1 112, one side of the slider 1132 is fixedly installed with the installation box 4, the screw rod 1134 is threadedly connected with the slider 1132, and the end of the output shaft of the motor 1133 is fixedly installed with the end of the screw rod 1134.

[0024] The base 1, the support rod 2 and the top plate 3 support the device as a whole. When the terminal is subjected to precision small hole punching, the terminal is first loaded to the middle of the base 1, and the motor 5 on the side of the installation box 4 is started at the same time. The output shaft end of the motor 5 drives the bidirectional screw 6 to rotate. Since the bidirectional screw 6 is rotatably arranged in the installation box 4, and the movable blocks 7 are respectively threadedly connected with the bidirectional screw 6, the rotation of the bidirectional screw 6 causes the two movable blocks 7 to slide relative to each other on the installation box 4. The bottom ends of the movable rods 8 rotatably arranged on the movable blocks 7 are respectively rotatably arranged on the pressure plates 9. With the movement of the movable blocks 7, the movable rods 8 push the pressure plates 9 to move vertically downward. At the same time, the ends of the pressure plates 9 are respectively slidably arranged on the limit rods 10, which guide and limit the movement of the pressure plates 9.

[0026] The terminal precision small hole punching die can press and fix the two sides of terminals of different sizes, has strong applicability, and effectively improves the stability during the precision small hole punching of the terminal. The overall structure of the device is simple, the operation is convenient, and the practicability is strong.

[0027] The bottom surface of the pressing plate 9 is paved with a pad, and the pad is made of rubber;

[0028] A rubber pad is laid on the bottom surface of the pressing plate 9. When the pressing plate 9 presses and fixes the terminal, the rubber pad can play a buffering role to prevent the pressing plate 9 from directly exerting excessive pressure on the terminal and damaging the terminal surface. At the same time, the rubber pad can also increase the friction between the pressing plate 9 and the terminal, making the pressing more stable.

[0029] The base 1 is provided with scales on the sides of the slideway 111;

[0030] The base 1 is provided with scales on the sides of the slideway 111. By observing the scales, the operator can conveniently adjust the positions of the terminal and the pressing plate 9 to improve the accuracy and efficiency of stamping.

[0031] A controller is provided on the top plate 3, and the controller is electrically connected to the stamping assembly 12, the motor 1 5 and the motor 2 1133 respectively;

[0032] The operator can control the start and stop of the stamping assembly 12, as well as the rotation direction and speed of motor 15 and motor 2 1133 through the controller, so as to control the entire stamping process, including the pressing and fixing of the terminal, the stamping position and the stamping speed, etc. The setting of the controller makes the operation of the entire device simple and convenient, and improves practicality and production efficiency.

[0033] Working principle:

[0034] The base 1, the support rod 2 and the top plate 3 support the device as a whole. When the terminal is subjected to precision small hole punching, the terminal is first loaded to the middle of the base 1, and the motor 5 on the side of the installation box 4 is started at the same time. The output shaft end of the motor 5 drives the bidirectional screw 6 to rotate. Since the bidirectional screw 6 is rotatably arranged in the installation box 4, and the movable blocks 7 are respectively threadedly connected with the bidirectional screw 6, the rotation of the bidirectional screw 6 causes the two movable blocks 7 to slide relative to each other on the installation box 4. The bottom ends of the movable rods 8 rotatably arranged on the movable blocks 7 are respectively rotatably arranged on the pressure plates 9. With the movement of the movable blocks 7, the movable rods 8 push the pressure plates 9 to move vertically downward. At the same time, the ends of the pressure plates 9 are respectively slidably arranged on the limit rods 10, which guide and limit the movement of the pressure plates 9. The two sides of the terminals are pressed and fixed by the two groups of pressure plates 9, and the stamping assembly 12 on the top plate 3 is started to stamp the terminals.

[0035] When the distance between the two pressing plates 9 needs to be adjusted according to the terminal size, the motor 2 1133 on the top plate 3 on one side is started simultaneously, and the output shaft of the motor 2 1133 rotates to drive the screw rod 1134 on one side to rotate simultaneously, and the screw rod 1134 on one side rotates simultaneously to drive the slider 2 1132 on the slideway 2 1131, thereby driving the installation box 4 and the pressing plate 9 to move horizontally, and the installation box 4 moves horizontally to drive the slider 1 112 to move horizontally on the slideway 111 through the limit rod 10;

[0036] A rubber pad is laid on the bottom surface of the pressing plate 9. When the pressing plate 9 presses and fixes the terminal, the rubber pad can play a buffering role to prevent the pressing plate 9 from directly exerting excessive pressure on the terminal and damaging the terminal surface. At the same time, the rubber pad can also increase the friction between the pressing plate 9 and the terminal, making the pressing more stable.

[0037] The base 1 is provided with scales on the sides of the slideway 111. By observing the scales, the operator can easily adjust the position of the terminal and the pressing plate 9 to improve the accuracy and efficiency of stamping.

[0038] The operator can control the start and stop of the stamping assembly 12, as well as the rotation direction and speed of the motor 15 and the motor 2 1133 through the controller, so as to control the entire stamping process, including the pressing and fixing of the terminal, the stamping position and the stamping speed, etc. The setting of the controller makes the entire device simple and convenient to operate, and improves the practicality and production efficiency;

[0039] The terminal precision small hole punching die can press and fix the two sides of terminals of different sizes, has strong applicability, and effectively improves the stability during the precision small hole punching of the terminal. The overall structure of the device is simple, the operation is convenient, and the practicability is strong.
