Drilling mold for intermediate body inclined hole

Abstract

The invention provides a drilling mold for an intermediate body inclined hole. By using the drilling mold, the continuous machining of two inclined holes in a supercharger volute casting can be realized, the drilling mold is unnecessary to be changed, the production efficiency is improved, the reserve quantity of the drilling molds is reduced, and the production cost is reduced. The drilling mold comprises a drilling mold structure and an inclined surface fixing structure. The drilling mold is characterized in that the inclined surface fixing structure comprises a fixed bracket and an inclined plate; the inclined plate is arranged on the fixed bracket in an inclined manner; the drilling mold structure is arranged on the surface of the inclined surface; and the angle between the inclined plate and the horizontal surface is equal to the angle between a drilling mold through hole and the horizontal surface.

Description

technical field [0001] The invention relates to a turbocharger volute processing device, in particular to an intermediate oblique hole drilling mold. Background technique [0002] The traditional turbocharger volute inclined hole drilling jig and inclined surface fixing device are an integral structure, that is, the bottom plate of the pressing end of the drilling jig is directly installed obliquely on the fixing bracket, so the inclination of the drilling jig cannot be adjusted, so that a pair of drilling jigs can only One type of oblique hole in the volute of the turbocharger is processed, and since there is only one through hole of the drilling jig on the jig rod of the drilling jig, it can only be drilled for one oblique hole inside the volute of the supercharger. When drilling the second oblique hole of the turbocharger volute, it is necessary to disassemble the drilling jig and install the supercharger volute to the matching drilling jig before drilling the oblique hol...

Problems solved by technology

[0002] The traditional turbocharger volute inclined hole drilling jig and inclined surface fixing device are an integral structure, that is, the bottom plate of the pressing end of the drilling jig is directly installed obliquely on the fixing bracket, so the inclination of the drilling jig cannot be adjusted, so that a pair of drilling jigs can only One type of oblique hole in the volute of the turbocharger is processed, and since there is only one through hole of the drilling jig on the jig rod of the drilling jig, it can only be drilled for one oblique hole inside the volute of the supercharger. When drilling the second oblique hole of the turbocharger volute, it is necessary to disassemble the drilling jig and install the supercharger volute to the matching drilling jig before drilling the inclined hole

The entire drilling process needs to be installed and disassembled twice, which is complicated and time-consuming, and corresponding drilling jigs need to be equipped for different inclined hole processing, resulting in high production costs
