Digital control vertical high precision honing machine

Abstract

The numerically controlled vertical high precision honing machine in the field of mechanical technology includes main shaft driving mechanism of vertical honing head, radial micro feeding mechanism of honing strip, high speed smooth honing head reciprocating mechanism, and digital control system. The connection mode includes vertical setting of the main shaft driving mechanism of vertical honing head and the radial micro feeding mechanism of honing strip on the honing machine bed, connection between the main shaft driving mechanism of vertical honing head and the radial micro feeding mechanism of honing strip via the feeding sleeve, and the connection of the high speed smooth honing head reciprocating mechanism to the main shaft driving mechanism of vertical honing head and the radial micro feeding mechanism of honing strip via bearing. The present invention has the advantages of simple structure, reasonable layout, high stability and reliability, etc.

Description

technical field [0001] The invention relates to a honing machine, in particular to a numerically controlled vertical high-precision honing machine. It belongs to the technical field of mechanical engineering. Background technique [0002] Automobiles and motorcycles are currently the manufacturing products with the largest volume, the widest range, and the best economic benefits in my country's manufacturing industry. In 2002 alone, the output of automobiles in my country exceeded 3 million, of which the output of cars also exceeded 1 million. The automobile society The number of car ownership exceeds 20 million. In 2003, the output of cars exceeded 2 million, and the output of automobiles exceeded 5.5 million. Cylinders and fuel injectors for automobiles and motorcycles are high-volume, high-precision, and difficult-to-process products. In order to meet the requirements of high dimensional accuracy and high shape accuracy, the last process must carry out high-precision hon...

AI Technical Summary

Problems solved by technology

"Its shortcomings are: because the spindle axis of the honing machine is in a horizontal position, the deflection caused by the gravity of the spindle itself affects the machining accuracy, and cannot meet the following requirements for high-precision workpiece inner hole processing: roundness tolerance 0.4μm, cylindricity Tolerance 1μm, straightness tolerance 1μm / 90mm, surface roughness lower than Ra0.04μm
