Abstract
Claims
1. A workpiece auxiliary positioning device for a lathe chuck, characterized by: It includes a mounting base that is detachably mounted in the center hole of the chuck, multiple elastic top pins arranged in a ring on the end face of the mounting base, and a positioning sleeve that is detachably mounted on the lathe tool holder for abutting the workpiece positioning surface.
2. The workpiece auxiliary positioning device for a lathe chuck according to claim 1, characterized in that: The mounting base has a mounting flange at one end, which is embedded in the center hole of the chuck by multiple screws. The end face of the mounting base away from the mounting flange has a ring array of multiple stepped holes for installing elastic top pins.
3. The workpiece auxiliary positioning device for a lathe chuck according to claim 2, characterized in that: The mounting base has an annular cross-section.
4. The workpiece auxiliary positioning device for a lathe chuck of claim 2, wherein: The elastic top pin consists of a top pin body with a "T" shaped cross-section, a spring, and a fixing screw. The top pin body and the spring are sequentially disposed in the stepped hole and fixed to the stepped hole by the fixing screw.
5. The workpiece auxiliary positioning device for a lathe chuck of claim 1, wherein: The positioning sleeve consists of a sleeve and a mounting rod. The sleeve can accommodate the part of the workpiece located at the front end of the positioning sleeve. The mounting rod is coaxially arranged with the sleeve and located on the back of the sleeve for fixed installation in the tool holder.
6. The workpiece auxiliary positioning device for a lathe chuck of claim 1, wherein: The tool holder is mounted on a multi-station tool head.
