The number of the first clamping mechanism, the number of the second clamping mechanism, and the number of the third clamping mechanism are all multiple. The control mechanism includes a sliding member slidably connected to the first clamping mechanism, a control air cylinder fixedly connected to the first clamping mechanism, a part touch switch fixedly connected to the first clamping mechanism, and a pneumatic valve connected to the part touch switch.

[0007] By adopting the above technical solutions, the first clamping mechanism, the second clamping mechanism, and the third clamping mechanism play a role in supporting and clamping the workpiece. After the user places the workpiece between the first clamping mechanism, the second clamping mechanism, and the third clamping mechanism, the edge of the workpiece is located between the sliding member and the first clamping mechanism. The user starts the control air cylinder to drive the edge of the workpiece to move, and at this time drives the workpiece to move in a direction close to the first clamping mechanism. When the workpiece abuts against the first clamping workpiece, the sliding block touches the surface of the part touch switch, and the pneumatic valve is opened. At this time, the workpiece is located at the designated position, and at the same time, the control mechanism controls the first clamping mechanism, the second clamping mechanism, and the third clamping mechanism to clamp the workpiece, improving the preparation degree of workpiece clamping. When welding, the position of the welded joint is more accurate, improving the welding quality.

The second clamping cylinder is communicated with the pneumatic valve.

[0011] By adopting the above technical solution, when the workpiece touches the part touch switch, the second clamping cylinder is activated, driving the second clamping member to rotate towards the surface of the workpiece. Finally, the surface of the second clamping member clamps the surface of the workpiece, achieving the purpose of the user clamping the workpiece.
