Abstract

The invention relates to a clamping device, in particular to a clamping device for a cutter sharpening major-diameter hollow center tap. The clamping device solves the problems that in an existing clamping device for the cutter sharpening major-diameter hollow center tap, the clamp cutter sharpening machining efficiency is low, and indexing table equipment is high in cost. A threaded through hole is machined in the center of the barrel bottom of a barrel, six kidney-shaped through holes are evenly distributed and machined in the middle portion of the barrel in the peripheral direction, the lower portion of a thread pitch indexing central spindle is installed in the barrel in a penetrating manner, and an inner circular bead hole is machined in the upper end face of the thread pitch indexing central spindle in the axial direction; a threaded hole is machined in the center of the inner circular bead hole, and a hexagon socket screw is in threaded connection to the threaded hole; threaded blind holes are evenly distributed and machined in the outer side wall of the upper portion of the thread pitch indexing central spindle in the peripheral direction, studs are arranged on the threaded blind holes, and six pin holes corresponding to the six kidney-shaped through holes are machined in the lower portion of the thread pitch indexing central spindle in the peripheral direction; and a first shaft pin and a second shaft pin each penetrate one kidney-shaped hole and are symmetrically inserted into one corresponding pin hole. The clamping device is used for the cutter sharpening major-diameter hollow center tap.

Description

technical field [0001] The invention relates to a clamping device, in particular to a clamping device for sharpening a large-diameter internal chip tap. Background technique [0002] In the process of rapid development of large-scale equipment, internal chip taps are also widely used to process screw holes. In the past, the sharpening of internal chip taps was done on the grinding machine, and the worktable of the index plate was used for processing. The existing processing method is as follows: first, the internal chip tap is installed on the fixture on the workbench, and the relative position of the emery wheel and the internal chip tap is adjusted by the depth of the chip removal groove. At this time, only one cutting edge can be sharpened. When sharpening the next cutting edge, it is also necessary to adjust the angle of the next cutting edge on the indexing knife of the workbench, and then move the workbench for clamping the chip tap axially for a height distance of a ...
