The invention relates to a positioner, which belongs to the field of machining tools. The positioner comprises a threaded shaft and a positioning rod, wherein the positioning rod is inserted into one end of the threaded shaft; the positioning rod and the threaded shaft are fixed through a nut A; a conical shaft is sleeved on the outer periphery of the threaded shaft; an expansion sleeve is sleeved on the outer periphery of the conical shaft; the outer periphery of the conical shaft is provided with an adjusting nut B for adjusting and fixing the expansion sleeve; the outer periphery of the threaded shaft is provided with a nut C for adjusting and fixing the conical shaft and the threaded shaft. According to the positioner, the positioning rod is in threaded connection with the threaded shaft, the length of the positioning rod is determined according to the requirement of machining size, and the expansion sleeve expands for fixing, so that positioning and clamping of a spring clamp of a numerical control lathe are finished rapidly, conveniently and accurately, axial positioning of workpieces is realized, and the axial positioning accuracy of workpieces in a machining process is ensured. Moreover, only a workpiece clamping tool needs to be considered, and the problem of positioning does not need to be considered, so that the universality of the tool is enhanced, and the variety, quantity and manufacturing of an auxiliary tool are reduced.
Description
technical field [0001] The invention relates to a positioner, which belongs to the field of machining tools. Background technique [0002] At present, spring collets are used to clamp workpieces on CNC lathes. In the axial positioning of workpieces, auxiliary tooling is generally used to achieve axial positioning through circumferential fixation. This method has the following disadvantages: [0003] 1. When the axial positioning dimension of the processed parts changes, tooling needs to be remade to meet the processing requirements. The production of a large number of tooling will consume a lot of manpower, material and financial resources, and its production cycle is long. [0004] 2. In the process of processing, the accuracy of axial positioning using auxiliary tooling often fails to meet the processing requirements of parts, and the production of auxiliary tooling is highly dependent on the operational ability and processing experience of skilled workers.
