Overall processing and measuring device and method for wax model of intermediate casing

Abstract

The invention discloses an integral machining and measuring device and a method for a wax model of an intermediate casing. The integral machining and measuring device comprises a fixture disc. The upper surface of the fixture disc is uniformly provided with sixteen circular shaft bosses. The circular shaft shape composed of sixteen circular shaft bosses is concentric with the fixture disc. A T-shaped slide way is formed between two adjacent circular shaft bosses. A profile standard gauge fixing groove is formed in one side of the outer edge of two adjacent circular shaft bosses on the both sides of the T-shaped slide way. The profile standard gauge fixing groove is perpendicularly arranged with the T-shaped slide way. A measuring device is arranged on the T-shaped slide way. The fixture disc is fixed on a lower fixing plate of the wax model of the annular integral casing by an angle positioning pin. The inner profile of the lower fixing plate of the wax model of the annular integral casing is matched with the outer profile of the circular shaft boss. According to the integral machining and measuring device and the method for the wax model of the intermediate casing, the integral machining and measuring device for the wax model of the intermediate casing performs one-time clamping machining and measurement on the wax model of the annular integral casing, so that the multiple assembling and adjusting time of a fitter to the module is reduced, the labor intensity of the fitter is reduced, and the machining precision and the machining efficiency of the wax model of the annularintegral casing are improved.

Description

technical field [0001] The invention belongs to the technical field of machining wax molds of casings, and in particular relates to an overall processing and measuring device and method for wax molds of intermediate casings. Background technique [0002] The casting of the intermediate casing of the key engine parts is cast with a special wax pattern. Due to the special shape of the positioning hole and the mounting seat in the intermediate casing structure, the special wax model of the intermediate casing casting is required to be designed to be detachable. The split structure, due to the limitation of the current factory equipment, the rotation of the spindle head of the existing five-axis machining center interferes with the inner diameter of the combined module ring, and it is impossible to assemble all the modules together for overall processing, even if the disc machining center uses The angle head can be processed as a whole, and the assembled modules will have surfac...
