[0002] The cylinder head, also known as the cylinder gland or cylinder end cap, is a key component in the hydraulic system that is fixed to the end of the cylinder. It is usually made of metal and its main function is to fix the cylinder and the sealing device, ensuring that the cylinder and the sealing components can maintain a stable connection when the hydraulic system is working normally. In addition, the cylinder head can also compensate for the processing errors and assembly gaps of the cylinder and the sealing parts, playing the multiple roles of sealing, protection and stabilizing pressure. It is an indispensable component of the hydraulic system and is of great significance to ensuring the normal operation of the entire system.

[0003] In the processing of the cylinder head, a machine tool fixture is required, with a three-jaw chuck as the clamping body. The product is clamped by the three-jaw. In the existing technology, the three-jaw chuck for the cylinder head has a fixed three-jaw shape and inner curvature, and an integrated installation structure, which is difficult to change. Although the three jaws can be moved for clamping, the inner curvature of the three jaws is difficult to adapt to cylinder heads with different outer diameters, which affects the clamping stability. At the same time, the clamping adjustment range of the three jaws is limited, especially for tank covers of various calibers. Therefore, the utility model proposes a cylinder head clamp to solve the problems existing in the existing technology. Utility Model Content
