Description

Technical Field

[0001] The utility model relates to the technical field of claw seats, in particular to a claw seat for a horizontal lathe. Background Art

[0002] The horizontal lathe is a common machine tool, which is characterized by the horizontal placement of the spindle. The spindle drives the workpiece to rotate as the main motion, and the tool holder drives the tool to move as the feed motion to complete the relative motion between the workpiece and the tool. It can perform various processes on various types of workpieces such as shafts, disks, rings, etc. It is often used to process the internal and external rotating surfaces, end faces and various internal and external threads of the workpiece. When the lathe processes parts, it is necessary to use a jaw seat to fix the parts to be processed. In the mechanical structure, the chuck is used to clamp and hold the workpiece parts, or to clamp and position the workpiece near the machine tool. Most of them are evenly distributed 360 degrees, so that the three jaws approach or withdraw from the center at the same time to complete the work;

[0003] In the prior art, when a clamping jaw is used to fix certain tubular parts, only three groups of clamping jaws are used to clamp the outer wall of the tubular parts with a certain pressure. When the tubular parts are subjected to strong external forces during the processing, the clamping jaws and the parts may be offset, thereby affecting the processing accuracy of the parts.
