Auxiliary clamping device for disc-hydraulic-type turbine disc tool

Abstract

The invention discloses an auxiliary clamping device for a disc-hydraulic-type turbine disc tool. The device comprises a clamp base, a beam, a left column, a right column and two pressure foot adjustment assemblies. The lower ends of the left column and the right column are symmetrically arranged on the clamp base, and the tops of the left column and the right column are fixedly connected with theleft and right ends of the beam. A downward tip is arranged in the middle of the beam, the two pressure foot adjustment assemblies are symmetrically arranged on the inner sides of the left column andthe right column, and each pressure foot adjustment assembly is composed of an oil cylinder, an upper lining, a pull rod, a pressure foot, a spring, a spacer, a lower lining, a nut, a disc spring, anadjustment lock nut and a positioning device. The auxiliary clamping device for the disc-hydraulic-type turbine disc tool applies stable and reliable pressure to the tool or a workpiece with the helpof pull force of the disc springs, the rotation tip is adopted for assisting in supporting and positioning the rotation tool or the workpiece, reinforcement is performed under the condition that processing is not influenced, and a turbine disc is conveniently and quickly clamped.

Description

technical field [0001] The invention relates to the technical field of fixture design in the field of mechanical processing, in particular to a disc hydraulic turbine disc tooling auxiliary clamping device. Background technique [0002] China's mechanical processing field is developing at a high speed, and products are constantly being updated; the trial production and processing of new products are inseparable from tooling and fixtures. Machine tool fixtures are used to fix workpieces. The process of workpiece centering, positioning and clamping is often used in the first process of process preparation, and the processing of this process directly affects the quality of subsequent processing. However, in the field of broaching tooling for turbine discs of aircraft engines, precision numerical control indexing discs are required in the process of broaching the tenons and grooves of turbine discs with a diameter less than 100 mm. The diameter of the indexing disc turntable u...

AI Technical Summary

Problems solved by technology

The diameter of the indexing disc turntable used to process such a small turbine disc is less than 90mm, and its stability is much worse than that of large-sized indexing discs. At the same time, the tooling of the turbine disc with a diameter of less than 100mm is very thin and the stability is weak.
