Coaxial double-head diamond boring lathe and fine boring method thereof

Abstract

The invention discloses a coaxial double-head diamond boring lathe and a fine boring method thereof. The coaxial double-head diamond boring lathe comprises a supporting frame, a step motor, a lead screw, a connecting frame, an upper alternating current motor, an upper transmission belt, an upper encoder, an upper main shaft, a clamp, a workbench, a hydraulic device, a lower main shaft, a lower encoder, a lower transmission belt, a lower alternating current motor, guide rails and a lathe body. The coaxial double-head diamond boring lathe can perform semi-fine boring and fine boring successively after one clamping, so that under the condition of coaxial machining, semi-fine boring and fine boring machining allowances are ensured and the balance of the fine boring allowance is ensured; by adopting a four-rail enclosed moving structure, the stability of a workpiece in the machining process and high precision are ensured; and after the workpiece is machined, through control of the hydraulic device, manual knife stripping is not required, but just the knife is taken by two hands, and through positioning of the encoders, the knife automatically drops from a cylinder sleeve. The coaxial double-head diamond boring lathe is simple to use, can reduce the labor intensity of working staff and improves the production efficiency.

Description

technical field [0001] The invention relates to machining equipment and a method thereof, in particular to a coaxial double-head diamond boring machine and a fine boring method thereof. Background technique [0002] A boring machine is a machine tool that mainly uses a boring tool to bore the existing holes of the workpiece. It can also perform drilling, milling, threading, and machining of outer circles and end faces with different tools and accessories. Generally, the rotation of the boring tool is the main motion, and the movement of the boring tool or workpiece is the feed motion. It is mainly used to process high-precision holes or complete the finishing of multiple holes at one time. In addition, it can also process other processing surfaces related to hole finishing. Boring machines are mainly divided into horizontal boring machines, coordinate boring machines, diamond boring machines, deep hole drilling and boring machines, floor boring machines and so on. The cur...

AI Technical Summary

Problems solved by technology

The current diamond boring machine generally requires two clamping and tool setting to complete semi-finish boring and fine boring, resulting in waste of time and accumulation of errors

At the same time, after the processing of the cylinder liner, the ordinary boring machine uses manual removal of the tool, which sometimes scratches the inner hole of the cylinder liner and reduces the production accuracy and efficiency.
