Abstract

The invention discloses a turbine assembly drill jig. The turbine assembly drill jig comprises a support base vertically mounted on a base, a rotating shaft horizontally penetrates the middle portion of the support base through a bearing and a bearing seat, a round plate for positioning the end surface of a turbine hub is mounted on the front portion of the support base on the rotating shaft, a grading plate for rotating the round plate for grading the turbine hub is mounted on the rear portion of the support base on the rotating shaft, a bending plate bent forwards is mounted at the upper end of the support base, and grooves for positioning the end surface of the turbine hub is arranged on the periphery of the round plate. Compared with the prior art, the turbine assembly drill jig can solve the problems that the accuracy of existing turbine hub drilling is difficult to ensure and the machining efficiency is low.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a drilling jig for machining multiple holes on a turbine hub assembly. Background technique [0002] The turbine hub assembly has a disc-shaped shell with a concave center and a protruding periphery. There are multiple holes in the protruding part of the periphery. The center of the shell is provided with a shaft hole perpendicular to the shell. The process requirements are relatively high. After assembly, the shaft must be able to Rotate easily by hand, while ensuring that the deflection between the positioning end face of the positioning plate and the outer circle cannot exceed 0.05mm, and the circumferential indexing error of the outer circle cannot exceed 0.08mm. Existing enterprises generally use a fitter to mark the multiple holes on the turbine hub assembly first, and then place the turbine hub assembly squarely on the workbench of the drilling machine, so that the posit...
