[0017] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Embodiment 1

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model proposes a clamp for a lathe, including a transmission cylinder 1 and a chuck assembly 3, a chuck groove 2 is provided on one side of the end face of the transmission cylinder 1, the chuck groove 2 is used to install the chuck assembly 3, the chuck assembly 3 is installed inside the chuck groove 2, the chuck assembly 3 is used to move in the chuck groove 2 to clamp the workpiece, a pre-clamping mechanism is installed on the opposite end face of the chuck assembly 3, the pre-clamping mechanism is used to pre-clamp the workpiece to improve the clamping efficiency of the workpiece, a through hole 6 is provided on the side of the transmission cylinder 1, the through hole 6 is used to install a fixing bolt 5, the through hole 6 is installed with a fixing bolt 5, the fixing bolt 5 is used to fix the transmission cylinder 1, the fixing seat 4 and the internal transmission mechanism, and a fixing seat 4 is installed on one end face of the transmission cylinder 1.

[0020] Furthermore, the chuck assembly 3 includes a pre-clamping mechanism and a chuck body 33. The chuck body 33 is used to clamp the workpiece. The pre-clamping mechanism includes a piston cylinder 31 and a piston rod assembly 32. The piston cylinder 31 is used to install the piston rod assembly 32 and fill the compressed gas. The piston rod assembly 32 is used to pre-clamp the workpiece. Multiple piston cylinders 31 are installed on the side of the chuck body 33 to fix the workpiece. The piston rod assembly 32 is installed inside the piston cylinder 31. The outer side of the piston rod assembly 32 is provided with an anti-slip layer 321. The anti-slip layer 321 is used to increase friction during pre-clamping installation to prevent falling off. A piston retaining ring 322 is installed on one side of the piston rod assembly 32. The piston retaining ring 322 is used to restrain the compressed gas to achieve the effect of piston rod popping out.

[0021] Furthermore, compressed gas is filled between the piston rod assembly 32 and the piston cylinder 31, and the compressed gas applies an outward force to the piston rod.

[0022] Furthermore, the anti-slip layer 321 of the piston rod assembly 32 can move to be parallel to the side end surface of the clamp body 33, so that the clamp body 33 can clamp the workpiece so that the workpiece can be clamped.

[0023] The working principle of the lathe clamp based on Example 1 is: the workpiece is placed in the middle of the clamp to clamp the workpiece. When placed between the clamp bodies 33, it first contacts the pre-clamping mechanism, and the pre-clamping mechanism clamps the workpiece as the clamp bodies 33 gather. As the piston rod assembly 32 is slowly compressed into the clamp body 33, the workpiece is then clamped by the clamp body 33.
