Problems solved by technology
[0003] When the three-jaw chuck fixes a workpiece with a long axial distance, it can only fix one end of the workpiece. During the processing of the workpiece, due to the long axial distance of the workpiece, it is easy to shake, resulting in the size of the workpiece being processed. Accurate, affecting the quality of the workpiece, may cause the rework of the workpiece, increase the cost output, and bring unnecessary trouble to the subsequent processing and production

The invention discloses a clamp for adjusting the axial length for vibration reduction high-precision three-jaw chuck assistance. The clamp comprises a fixed disc, a clamp body and a three-jaw chuck.The three-jaw chuck is arranged at the bottom of the clamp body. A sleeve is welded to the upper portion of the three-jaw chuck. The interior of the fixed disc is elastically connected with an arc clamping plate through a compression spring. A first spiral fixing bolt is arranged inside the compression spring. The disc moves to precisely adjust the axial distance of an adjusting workpiece, and meanwhile, a clamping rack is in meshed connection with a gear inside the sleeve, so that the movable clamping rack is more stably fixedly connected with the sleeve at the designated position, meanwhile,the arc clamping plate can be in tight fit with the axis of the workpiece through the first spiral fixing bolt, the protruding axial portion is well fixed, the vibration effect during workpiece machining is effectively lowered, and the workpiece machining precision is improved.
Description
technical field [0001] The invention relates to the technical field of lathe workpiece fixing processing, in particular to a jig for adjusting the axial length of a high-precision three-jaw chuck with vibration reduction. Background technique [0002] The three-jaw chuck is composed of the chuck body, the movable jaws and the jaw driving mechanism. The three-jaw Under the guide part of the three claws on the chuck, there are threads that mesh with the plane threads on the back of the bevel gear. When the small bevel gear is turned with a wrench through the square hole, the bevel gear rotates, and the plane threads on the back drive the three gears at the same time. The three jaws approach or withdraw from the center to clamp workpieces with different diameters, and the three jaws are replaced with three anti-jaws to install workpieces with larger diameters. [0003] When the three-jaw chuck fixes a workpiece with a long axial distance, it can only fix one end of the workpie...
