Lathe chuck with axial end surface retaining device

Abstract

The invention discloses a lathe chuck with an axial end surface retaining device. The lathe chuck comprises a chuck body (1), a spindle (2), a centre body (3), a lock nut (4) and a spiral retaining sleeve (5), wherein the centre body (3) is installed on the spindle (2); the lock nut (4) is installed on the centre body (3); and the spiral retaining sleeve (5) is installed on the centre body (3) and located at the right end of the lock nut (4). The centre body (3) stretches into the chuck body (1) to jack a workpiece. The right end surface of the spiral retaining sleeve (5) is a plane or a plane with a thread. According to the provided lathe chuck with the axial end surface retaining device, the structural design is reasonable, operation is convenient and clamping is stable and reliable; especially, the workpiece can be prevented from sliding axially and can be machined through one-time clamping, and the machining efficiency is higher; and moreover the machined workpiece is high in precision, quality and practicality.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a lathe chuck with an axial end face stop device. Background technique [0002] When the lathe is processing the workpiece, such as the workpiece with the center hole and the workpiece with or without holes on the end surface. The stability of the workpiece clamping affects the quality of the processing. In the prior art, after the lathe uses the chuck to clamp the workpiece, due to the unreasonable structural design, when the workpiece is processed, the workpiece will slide a small amount in the axial direction, resulting in clamping Unsteady, affecting processing quality. And in the prior art, the repeated adjustment of the chuck is tightened, the clamping of the workpiece is cumbersome, and the production efficiency is low. [0003] Therefore, it is very necessary to research and develop a lathe chuck with an axial end face stop device that has reasonable structure design, convenient u...
