Abstract

The invention discloses a special fixture for boring hole groups in bearing blocks of drum-shaped box bodies. The fixture comprises a fixture seat (13), a fixture body (10) and a clamping body; the fixture seat (13) is fixedly connected with a workbench (16) of a boring mill (1) by the aid of a T-shaped bolt; the right end surface of the fixture body (10) abuts against the fixture seat (13) by the aid of a tensioning screw rod (15) in a back-to-back manner; a clamping seat (6) of the clamping body is fixedly connected with the fixture body (10) by the aid of a bolt (18); and the special fixture for boring the hole groups in the bearing blocks of the drum-shaped box bodies is formed as a whole. The fixture is simple in structure, convenient to mount, accurate in positioning, firm in clamping and easy to adjust.

Description

technical field [0001] The invention relates to a machining fixture, in particular to a special fixture for boring a drum-shaped box bearing seat hole group. Background technique [0002] The bearing seat holes for the drive shaft installed on the box are mostly processed by boring, and the seat holes appear in groups in most cases and are distributed in a certain way. When boring, if the shape of the box and the distribution of the seat holes are irregular, such as drum-shaped box parts, then the positioning, clamping, adjustment, and processing of the box are more difficult, and the processing efficiency of the seat hole group is low. Contents of the invention [0003] The object of the present invention is to design a special jig for boring the hole group of the drum-shaped box bearing seat, which has the advantages of simple structure, convenient installation, accurate positioning, firm clamping and easy adjustment. [0004] The technical solution of the present inven...
