Abstract

The invention provides a portable clamp, comprising a tailstock apex; the tailstock apex is used for pushing against one end of a workpiece when a lathe clamps the workpiece; the portable clamp also comprises a chuck body, clamping jaw pushing parts, a centering apex and a fixing part; a clamping surface of the chuck body is provided with more than three clamping jaw chutes, each clamping jaw chute is provided with one clamping jaw pushing part, and the center of the chuck body is provided with a central shaft hole; each clamping jaw pushing part comprises an inner cushion block, a fixing block, a sliding block and a fixing cutting edge, wherein the fixing cutter edge is arranged on the top surface of the clamping jaw pushing part, the fixing block is provided with a fixing hole, and the chute bottom of each clamping jaw chute is provided with a blind hole. The portable clamp in the technical solution clamps from the end surfaces of two ends of the workpiece, such that the whole workpiece can be machined during machining, secondary clamping is avoided, the coaxiality of the workpiece is improved, the clamping is convenient and great convenience is provided for machining.

Description

technical field [0001] The invention relates to the field of lathe clamps, in particular to a portable clamp. Background technique [0002] In today's lathe processing, when it comes to the processing of shafts, the three-jaw chuck is basically used for clamping, or the top and chicken heart clamp are used for clamping. Perform secondary clamping processing so that the part of the workpiece that is clamped can be processed. After the secondary clamping, the coaxiality of the workpiece will deviate, which will lead to machining errors. In this way, restorative reprocessing must be carried out. If the precision requirements are high, it is easy to produce waste products, which in turn makes Greatly increased production costs. [0003] The Chinese patent literature discloses a centrifugal face drive top (publication number: CN 204194855U, open date: 2015.03.11). In the centrifugal face drive top, the clamp body is an integrated device, which utilizes the lathe spindle taper h...
