AI Technical Summary
Technical Problem
Traditional lathe fixtures have problems with operational complexity and damage to the workpiece surface, resulting in uneven processing or damage to the workpiece.
Method used
A lathe rear pulling and compression clamp is designed. By setting open grooves on both sides of the chuck to provide a through placement space for the pulling arm, the front and back movement of the pulling arm is realized, and the clamping hand is close to or away from the fixture base, and stable clamping and loosening of the workpiece is realized.
Benefits of technology
By precisely controlling the clamping force, the fixture avoids uneven deformation or damage of the workpiece, improves processing accuracy and efficiency, and reduces damage to the workpiece surface.

Abstract
The utility model provides a backward-pulling compression type clamp for a lathe. The backward-pulling compression type clamp is characterized in that a through hole is formed in the middle of a chuck; open slots for placing the pull arms in a penetrating manner are formed in two sides of the chuck; the rear end of the chuck is connected with a spindle of the lathe; the clamp base is arranged on the front side of the chuck; the tightening device comprises a pulling seat and a pulling arm; the pulling seat is arranged in the pulling hole, the two sides of the pulling seat are connected with the pulling arms respectively, and the tail end of each pulling arm is provided with a clamping hand; the clamping hand abuts against the front side of a workpiece, the clamp base abuts against the rear side of the workpiece, and the workpiece is clamped by the clamping hand and the clamp base. According to the utility model, the clamping hands can be correspondingly close to or far away from the clamp base by driving the pull arms, so that a workpiece is clamped or loosened.
