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...
