Drilling device for stainless steel precision casting

Abstract

The invention discloses a drilling device for a stainless steel precision casting. The drilling device comprises a device body, a guide rotating rod, a clamping block, a supporting column and a limiting spring, main guide threaded rods are arranged on the front side and the rear side of the interior of the device body in a penetrating mode correspondingly, and a main motor is fixedly arranged in the middle of the outer wall of the right side of the device body; and the left end of a guide rotating rod on the top face of the device body is fixedly connected to the end of an output shaft of an auxiliary motor, supporting columns are fixedly arranged on the left side and the right side of the top face of the device body, protruding blocks are fixedly arranged on the left side and the right side of the outer wall of the guide rotating rod on the top face of the device body, and grooves are formed in the left side and the right side in a bevel gear on the outer wall of the guide rotating rod. According to the drilling device for the stainless steel precision casting, while the main guide threaded rods drive the clamping block to transversely move, auxiliary guide threaded rods drive the clamping block to longitudinally move, the clamping blocks of different specifications and sizes can be conveniently clamped and limited by the clamping block, and the situation that a drilling machine deviates when working is prevented.

Description

technical field [0001] The invention relates to the technical field of processing stainless steel precision castings, in particular to a drilling device for stainless steel precision castings. Background technique [0002] Stainless steel precision castings refer to the general term for steel castings made of various stainless steel materials. They are mainly used in various medium corrosion conditions. Generally, the carbon content is above 0.20%. According to the metallographic structure, stainless steel is divided into ferritic stainless steel, horse Tentenitic stainless steel, austenitic stainless steel and duplex (ferrite in austenitic matrix) stainless steel currently require a drilling process during the processing of stainless steel precision castings. [0003] However, during the drilling process of most stainless steel precision castings, the fixed parts of the traditional casting drilling equipment are not firmly fixed to the processed castings, and loosening will...

Problems solved by technology

[0005] The purpose of the present invention is to provide a drilling device for stainless steel precision castings, to solve the problem that the fixed parts of the traditional casting drilling equipment have a problem with the drilling process of most stainless steel precision castings in the market. The processed castings are not firmly fixed and will loosen during the drilling process. The drilling parts of the casting drilling equipment are inconvenient to operate, and the existing drilling equipment cannot clamp stainless steel castings with large specifications. In the process of machining and drilling stainless steel castings of different specifications, it is necessary to replace the clamped workpiece, and the inconvenient adjustment leads to the problem of low drilling efficiency.
