High-precision machining device

Abstract

The invention discloses a high-precision machining device. The high-precision comprises a grinding device and a mechanical arm used for clamping a workpiece, wherein the mechanical arm comprises a driving structure and a clamping assembly arranged on the driving structure, and the clamping assembly is formed by combining a main pipe body and a telescopic electric cylinder arranged in an inner cavity of the main pipe body; The clamping assembly formed by combining the main pipe body and the telescopic electric cylinder is arranged, two layers of mounting holes are formed in the front side wall of the main pipe body, mounting seats are fixedly arranged in the mounting holes, positioning pieces formed by combining supporting seats, supporting rods, adsorption heads and reset springs are arranged in first cavities and second cavities of the mounting seats, when the clamping assembly clamps the to-be-clamped tubular workpiece, the clamping assembly clamps and fixes the to-be-clamped tubular workpiece from an inner cavity of the to-be-clamped tubular workpiece, therefore a worker can conveniently grind the outer side wall of the to-be-clamped tubular workpiece at a time, and then the overall machining efficiency of the device is effectively improved.

Description

Technical field [0001] The present invention relates to the field of mechanical processing, and is specifically a highly accurate machining device. Background technique [0002] Mechanical processing refers to a process of changing the shape size or performance of the workpiece by a mechanical device. The difference in processing mode can be divided into cutting and pressure processing. During the production process, the process of changing the shape, size, position and nature of the production object, etc., making it a process of finished or semi-finished products. It is the main part of the production process. The process can be divided into process, forging, stamping, welding, machining, assembly, etc., mechanical manufacturing process, generally refers to the machining process of the part, and the sum of the assembly process of the machine, and other processes are called auxiliary. Procedure such as transportation, storage, power supply, equipment maintenance, etc. The proces...

AI Technical Summary

Problems solved by technology

[0003] In the machining process, each process will involve the clamping of the workpiece, but the traditional tubular workpiece clamping mechanism is usually clamped on the outside of the tube workpiece, resulting in grinding of the tube workpiece on the outer wall During the polishing process, it is necessary to change the clamping position of the workpiece once in the grinding step, which affects the processing efficiency, and the process of adjusting the clamping position for many times can also easily lead to a decrease in the machining accuracy of the workpiece
