Numerical control vertical high-precision honing machine and its honing method

Abstract

The invention relates to a numerically controlled vertical high-precision honing machine and a honing method thereof. The honing machine comprises a processing station upright post component, and a main shaft supporting plate screw rod and a processing station clamp supporting plate screw rod which are parallel are vertically arranged in the processing station upright post component; a main shaft supporting plate and a processing station clamp supporting plate are arranged outside the processing station upright post component; the main shaft supporting plate is connected with a screw rod nut on the main shaft supporting plate screw rod through a main shaft supporting plate connecting plate; the processing station clamp supporting plate is connected with a screw rod nut on the processing station clamp supporting plate screw rod through a processing station clamp supporting plate connecting plate; the contact surfaces of the supporting plates and an upright post are glidingly fixed by a guide rail and a guide block respectively; the lower end surface of a machine tool main shaft component is connected to a honing tool; full-floating honing tools are fixed to the upper surface of the processing station clamp supporting plate to be opposite to the honing tool, and the screw rods are controlled and connected by a stroke motor. When the honing machine and the honing method provided by the invention are used for precisely honing the inner surface of a hole-like part, the size precision, the surface roughness and the geometrical shape precision of a hole can be greatly improved.

Description

[0001] [technical field] [0002] The invention relates to the technical field of honing machines, in particular to a numerically controlled vertical high-precision honing machine and a honing method thereof. [0003] [Background technique] [0004] 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 stock of more than 20 million vehicles, the output of cars in 2003 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, high-precision honing must be carried out in the...

AI Technical Summary

Problems solved by technology

In order to meet the requirements of high dimensional accuracy and high shape accuracy, high-precision honing must be carried out in the last process. However, most of the domestically developed honing machines are horizontal and manually fed, and the processing accuracy cannot meet the requirements of these high-performance products.
