High small ultrasonic polishing, collating equipment in use for parts of axes, and processing method

Abstract

An efficient ultrasonic polishing apparatus for the axle-type parts is composed of a HF (200000-300000 H2) ultrasonic generator and a grinding head, and is installed to the cutting-tool carrier. Its polishing method features that the part to be polished is fixed to a lathe.

Description

Technical field: [0001] The invention relates to the metal cold processing industry of mechanical manufacturing and the technical field of surface finishing processing of shaft parts, in particular to a high-efficiency ultrasonic finishing processing equipment and processing method for bright finishing the surface of shaft parts. Background technique: [0002] At present, the commonly used technologies for surface finishing of domestic shaft parts and their respective defects are: [0003] 1. Grinding: On the cylindrical grinding machine, the workpiece is rotated, and the abrasive grains of the emery wheel are used to rotate at high speed and radial micro-cutting is a processing method for cutting metal. The surface roughness can reach Ra1.6μm-Ra0.8μm, but the efficiency is low, the grinding capacity is limited, and the grinding machine exceeds the limit for large shaft parts or parts with complex structures. [0004] 2. Polishing: On a lathe, the workpiece is rotated, and ...

Problems solved by technology

But the efficiency is low, the surface roughness can only reach Ra3.2μm-Ra1.6μm, and the shape and position tolerance is large

[0005] 3. Abrasive belt grinding: on the lathe, the processing is flexible and convenient, the work efficiency is low, and the effect of improving the geometric accuracy of the part surface is not obvious. The shape and position tolerance is greatly affected by the lathe. If the lathe processing error is large, the grinding error will be large. On the contrary, it is small; the surface roughness can only reach Ra1.6μm

[0006] The above-mentioned traditional surface finishing technology has great limitations, and the machining accuracy is not very high, resulting in low assembly accuracy of the product. Under the same conditions, the higher the surface geometric accuracy of the parts, the more accurate the installation accuracy of the parts, and the practicality of the product. better sex, longer life

Conversely, the lower the surface geometric accuracy of the part, the poorer the installation accuracy of the part, and the product will appear in the form of unreasonable wear, erosion, melting and bonding, surface material transfer or fatigue fracture source caused by processing stress during use. The failure of the product seriously affects the performance of the product and shortens the service life
