[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] In the production process of core-pulling rivets, metal clamps are essential tools. They are used to fix and position rivets, ensuring the accuracy and stability of the production process.

[0025] When rivets are clamped in production, a pile of disordered rivets needs to be placed neatly one by one, with the rivet cap and rivet tip facing the same direction, and then the rivets are placed one by one. Not only is the process complex and tedious, but also the production speed is slow.

[0026] Please refer to Figs. 1-3As shown, the embodiment provides a metal clamp for producing core-pulling rivets, which comprises a base 1. In order to clamp multiple rivets, the base 1 is fixedly connected with a support plate 11 at the top. The left and right sides of the support plate 11 are fixedly connected with the ends of springs 12 at the top. The other ends of the springs 12 are fixedly connected with a placing box 16. The top of the placing box 16 is fixedly connected with a baffle 17. The bottom of the placing box 16 is provided with a T-shaped sliding groove 161. The inner wall of the T-shaped sliding groove 161 is slidably connected with a T-shaped sliding block 21. The bottom of the T-shaped sliding block 21 is fixedly connected with a clamping plate 2. The clamping plate 2 can move along the length direction of the T-shaped sliding groove 161 on the T-shaped sliding block 21, and can be suitable for rivets of different thicknesses. However, the existing metal clamp for producing core-pulling rivets can only distinguish the front and back of a rivet and a rivet cap during use. The clamp is complex, which increases the operation difficulty. The rivet that has been distinguished needs to be collected, which affects the efficiency.

[0027] The improvement of the embodiment is that:

[0028] Firstly, the motor 13 rotates to drive the rotating shaft 14 to rotate. Then, the rotating shaft 14 rotates to drive the cam 15 to rotate. Next, the cam 15 strikes the bottom of the placing box 16 to drive the placing box 16 to vibrate. The placing box 16 vibrates to shake the end of the rivet without the rivet cap into the clamping plate 2. The clamping plate 2 can quickly distinguish the two ends of the rivet by blocking the end of the rivet cap at the top of the clamping plate 2. The clamping plate 2 can clamp multiple rivets at the same time. By rotating the knob 23 to drive the bolt 22 to move, the T-shaped sliding block 21 slides by the movement of the bolt 22. The clamping plate 2 moves forward and backward by the sliding of the T-shaped sliding block 21. The distance between the clamping plates 2 can be changed by the forward and backward movement of the clamping plate 2, which can be suitable for clamping rivets of different thicknesses.

[0029] In order to prevent the T-shaped sliding block 21 from sliding randomly, the placing box 16 is internally threadedly connected with the bolt 22. The end of the bolt 22 is rotatably connected in the T-shaped sliding block 21. The other end of the bolt 22 is fixedly connected with the knob 23. First, the knob 23 rotates to drive the bolt 22 to move. Then, the bolt 22 moves to drive the T-shaped sliding block 21 to slide, so that the T-shaped sliding block 21 does not slide randomly.

[0030] In order to distinguish the two ends of the rivet, the top of the support plate 11 is fixedly connected with a side plate 111. The side plate 111 is rotatably connected with the rotating shaft 14. The outer surface of the rotating shaft 14 is fixedly connected with the cam 15. First, the rotating shaft 14 rotates to drive the cam 15 to rotate. Then, the cam 15 strikes the bottom of the placing box 16 to make the placing box 16 vibrate. Next, the placing box 16 vibrates to drive the rivet in the placing box 16 to vibrate. The end of the rivet without the rivet cap falls into the clamping plate 2. At the same time, the top of the clamping plate 2 clamps the rivet cap on the clamping plate 2, so that the two ends of the rivet can be distinguished.

[0031] Secondly, in order to facilitate the rotation of the rotating shaft 14, the motor 13 is fixedly connected to the front surface of the side plate 111, the output shaft end of the motor 13 extends into the inside of the side plate 111, and is fixedly connected to the end of the rotating shaft 14. First, the motor 13 drives the rotating shaft 14 to rotate, and then the rotating shaft 14 is facilitated to rotate, and the degree of automation is improved.

[0032] Considering that the rivet is easy to shake down from between the clamping plates 2 after sliding out of the inside of the placement box 16, the long-shaped sliding groove 162 is formed in the right side surface of the placement box 16, the moving block 31 is slidably connected to the inner wall of the long-shaped sliding groove 162, the supporting plate 3 is fixedly connected to the outer surface of the moving block 31, the end of the air cylinder 32 is fixedly connected to the inner surface of the long-shaped sliding groove 162, and the other end of the air cylinder 32 is fixedly connected to the outer surface of the moving block 31. First, the air cylinder 32 drives the moving block 31 to slide, and then the moving block 31 drives the supporting plate 3 to move up and down. Then, the supporting plate 3 can be applied to the rivet caps of different heights of the rivet, and the supporting plate 3 blocks the rivet cap to prevent the rivet from shaking down from between the clamping plates 2. After the rivet slides out of the inside of the placement box 16, it is not easy to shake down from between the clamping plates 2.

[0033] In summary, the working principle of the present scheme is as follows:

[0034] The knob 23 is manually rotated, the knob 23 is driven to rotate by the screw 22, the T-shaped sliding block 21 is driven to slide by the screw 22, the clamping plate 2 is driven to move forward and backward by the T-shaped sliding block 21, the clamping plate 2 is moved to the ideal distance by moving forward and backward, the distance between the two clamping plates 2 can drop into the width of the rivet without the rivet cap, but the width cannot be wider than the rivet cap. In this way, the end without the rivet cap will drop between the clamping plates 2, and the end with the rivet cap will be stuck on the clamping plate 2. In this way, multiple rivets can be distinguished and clamped at the same time. The motor 13 is connected to the power supply, the rotating shaft 14 is driven to rotate by the motor 13, the cam 15 is driven to rotate by the rotating shaft 14, the placement box 16 is vibrated by the cam 15 knocking on the bottom of the placement box 16, the end of the rivet without the rivet cap is vibrated and dropped between the clamping plates 2 by the vibration of the placement box 16, the air cylinder 32 is extended to the ideal length according to the length of the rivet cap, the moving block 31 is driven to slide by the air cylinder 32, the supporting plate 3 is driven to move up and down by the moving block 31, the supporting plate 3 is blocked above the rivet by moving up and down, but does not fit the top of the rivet cap, effectively preventing the rivet from being shaken out of the clamping plate 2 due to vibration, and allowing the rivet to slide on the clamping plate 2 to the next processing link. Multiple rivets can be clamped at the same time, and can be applied to rivets of different thicknesses.

[0035] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
