Double-head coaxial boring and milling machining device for machining

Abstract

The invention discloses a double-head coaxial boring and milling machining device for machining, relates to the technical field of machining, and solves the problems that an existing machine tool canonly drill one end of a shaft part at a time, the other end of the shaft part can be drilled only by clamping the part again, the steps are tedious, hole sites at the two ends of the part are prone todeviation, and the production precision of parts is influenced. The double-head coaxial boring and milling machining device for machining comprises coaxial machining mechanisms, and the number of thecoaxial machining mechanisms is two. When the device is used for drilling the two ends of the shaft part, drill bits of two drill bit clamps can be coaxially driven to rotate through a transmission shaft, the two coaxial machining mechanisms can independently move, so that operation of drilling the two ends of the shaft part can be completed at the same time, one-time forming is achieved, the part does not need to be clamped again, drilling positioning is accurate, the operation is convenient and flexible, machining efficiency is high, and practicability and flexibility of the device are improved.

Description

technical field [0001] The invention belongs to the technical field of machining, and more specifically relates to a double-head coaxial boring and milling device for machining. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. According to the difference in processing methods, it can be divided into cutting processing and pressure processing. The most commonly used equipment in mechanical processing is machine tools. It is generally divided into metal boring and milling machine tools, cutting machine tools, forging machine tools and woodworking machine tools, etc., but parts with high precision requirements and fine surface roughness requirements generally need to be processed on machine tools. [0003] For example, in the patent with the application number CN201610765693.2, a mechanical processing device is disclosed, including a base, a working box is fixedly installed on the top...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a double-head coaxial boring and milling processing device for mechanical processing, to solve the problem that the existing machine tool can only adjust the shaft at one time when drilling or processing the two ends of the shaft parts. One end of the part is drilled, and after one end of the part is drilled, the part needs to be re-clamped to drill the other end. The steps are cumbersome, and the part is prone to eccentricity when the part is re-clamped, causing the hole positions at both ends of the part to deviate. Affects the production accuracy of parts, and the problem of low practicability
