Abstract

The invention discloses a drilling jig for a speed reducer connecting cover and aims to provide the drilling jig for the speed reducer connecting cover, which has a simple structure, small hole position errors and high production efficiency. The drilling jig comprises the speed reducer connecting cover (1), a lower template (3) provided with a guide post (2), an upper template (5) provided with a positioning lug boss (4), and a clamping device (6), wherein the upper template (5) is provided with a guide hole (7) and a guide post hole (8) and is connected with the guide post (2) in a sliding way through the guide post hole (8); the lower template (3) is provided with a positioning lug boss (9), a guide hole (10) and a screw hole (11); the clamping device (6) consists of a screw (12) and an open spacer (13) and is arranged in the center of a jig body; and the upper surface of the upper template (5) is provided with a through hole (14) through which the entire screw (12) can pass and a counter bore (15) into which the tail of the screw (12) and the open spacer (13) can sink. The drilling jig can realize the processing of holes on two surfaces with certain position requirements on an ordinary drilling machine.

Description

technical field [0001] The invention relates to a drilling jig, in particular to a jig for processing holes with relative positions on both surfaces of a connection cover of a reducer. Background technique [0002] The connection cover of the reducer has a cylindrical structure, with a through hole in the center and flanges with stepped holes at both ends. There are 4 holes on the circumference of the lower flange and 6 holes on the circumference of the upper flange, which are connected with the left and right deceleration respectively. If the machine is rigidly connected, the requirements for the relative position of the holes are relatively high. In the prior art, ordinary drilling machines are generally used for processing, and two sets of fixtures are usually used. Firstly, the bottom surface faces upwards, and the bottom surface is provided with a lower template with guide holes, screws, pressure plates and positioning bosses, and the lower flange step holes are used fo...
