Convenient and fast type hardware tool clamp

Abstract

The invention discloses a convenient and fast type hardware tool clamp. The hardware tool clamp comprises a bottom plate, a pair of sliding plates and two adjusting bolts; the left side edge and theright side edge of the bottom plate are provided with supporting plates correspondingly, the two supporting plates are arranged in parallel, the front side edge and the rear side edge of the bottom plate are provided with sliding grooves correspondingly, and the two sliding grooves are arranged in parallel; the bottoms of the pair of sliding plates are connected with the sliding grooves in a sliding mode through sliding blocks correspondingly, threaded holes are formed in the two supporting plates correspondingly, the two adjusting bolts are in threaded connection with the corresponding threaded holes correspondingly, and the ends of the two adjusting bolts are connected to the outer sides of the corresponding sliding plates correspondingly; and semicircular notches are formed in the innersides of the two sliding plates correspondingly, semi-arc clamping pieces are arranged in the semicircular notches, and the two semi-arc clamping pieces are oppositely arranged. According to the hardware tool clamp, the structure is simple and reasonable, producing and manufacturing are easy, the design is ingenious, the conception is novel, a workpiece can be effectively fastened, a milling cutter or a machined article can not be fractured, and economic loss is avoided.

Description

technical field [0001] The invention relates to a structure of a clamping device, in particular to a portable hardware fixture. Background technique [0002] A milling machine mainly refers to a machine tool that uses a milling cutter to process various surfaces on a workpiece. Usually the rotation of the milling cutter is the main movement, and the movement of the workpiece (and) the milling cutter is the feed movement. It can process planes, grooves, various curved surfaces, gears, etc. A milling machine is a machine tool with a wide range of uses. It can process planes (horizontal planes, vertical planes), grooves (key slots, T-shaped slots, dovetail slots, etc.), toothed parts (gears, spline shafts, sprockets), Spiral surfaces (threads, spiral grooves) and various curved surfaces. In addition, it can also be used to process the surface and inner hole of the rotating body and perform cutting work. When the milling machine is working, the workpiece is installed on the ...

AI Technical Summary

Problems solved by technology

The clamps currently used are relatively tight for the processed items, which may easily cause the milling cutter or the processed items to break during the processing, resulting in huge economic losses.
