Special clamp for drilling cambered surface of shaft part and use method

Abstract

The invention relates to the field of machining, in particular to a special clamp for drilling a cambered surface of a shaft part. The special clamp for drilling the cambered surface of the shaft partcomprises a base (2) and a drill plate (4); a baffle (3) with a semi-cylindrical cavity, a positioning block A and a supporting plate (6) are sequentially arranged on the base (2); centers of the baffle (3), the positioning block A and the supporting plate (6) remain on the same plane; a positioning block B with a semi-cylindrical cavity is arranged on the drill plate (4), and the positioning block B and the positioning block A are concentric when closed; the drill plate (4) is connected with the base (2) through a cylindrical pin (12) to form a hinged mechanism, so that the purpose of simplyand fast assembling and disassembling the part is achieved; a swing bolt (10) is arranged on the edge of an open end of the formed hinged mechanism; and a drill sleeve (5) is arranged on the drill plate (4). The special clamp has the characters that the structure is simple, operation is convenient, the cost is saved, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a special fixture for drilling the arc surface of shaft parts and a use method. Background technique [0002] The workpiece is cylindrical and small in size. When drilling holes on its arc surface, it often slips or becomes loose. However, it is not easy to position and fix the workpiece. If it is processed by group clamping, the cost is relatively high. High, loading and unloading is also more troublesome, resulting in increased labor intensity of the operator, and the processing of different batches of workpieces must reassemble the fixture, which ultimately leads to low work efficiency and directly affects the production schedule. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a special fixture for drilling the arc surface of shaft parts, so as to realize the technical problems of positioning an...
