[0007] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a variable pressure high-precision external curved surface grinding device based on a flexible grinding disc and adaptive variable pressure for high-precision machining of external curved surface parts. Its use method; in order to solve the problem that the flexible grinding wheel disc will become loose after long-time grinding, the present invention creatively proposes a thermal expansion type non-metallic grinding chamber based on the principle of flexible shell and film and the principle of turning harm into benefit The capsule assembly uses the heat inevitably generated during the grinding process to heat the air in the hollow chamber of the grinding base ring, and further supports the non-metallic semi-flexible grinding sand ring through the expansion of the air in the hollow chamber of the grinding base ring, which is It can effectively prevent the substrate of the flexible grinding wheel from becoming loose due to thermal expansion, and can also conduct the originally harmful heat through a suitable channel, so that it has a favorable effect; in order to solve the fit between the grinding disc and the curved surface during surface grinding The problem is not high. Based on the principle of self-service, the present invention creatively proposes a grinding head-driven feeding device. Through the ring-shaped uniformly distributed grinding head-driven feeding device, the twisted grinding ring can be self-adaptive according to the shape of the part. Angle adjustment, the self-resetting telescopic torsion assembly in the same tilting direction as the torsion grinding ring is elongated, and the self-resetting telescopic torsion assembly in the opposite direction to the torsion grinding ring is compressed; and the torsion grinding ring's The self-resetting telescopic torsion assembly on both sides of the torsion direction rotates through the spherical surface of the piston edge of the torsion telescopic rod and the spherical inner cavity of the telescopic sleeve of the special-shaped telescopic sleeve. In the notch at the end of the bushing, thereby compensating the lateral deflection of the self-resetting telescoping torsion assembly on the side
[0008] In order to solve the problem that the ground tiny particles are caught between the grinding disc and the workpiece in the following grinding process, which may easily scratch the workpiece or cause over-processing, the present invention creatively proposes an automatic chip removal method based on the principle of self-service The blower fan, through the rotating power of the grinding, drives the automatic chip removal blower blowing downward to rotate, so as to actively remove the fine particles that may have negative impacts. With the conical diversion top, without any independent drive device Under this condition, the technical effect of actively blowing air and removing debris particles is realized

The invention discloses a variable-pressure type high-precision outer curved surface grinding device and a using method thereof. The variable-pressure type high-precision outer curved surface grinding device comprises a self-adaptive torsion type annular grinding component, a grinding head driving and feeding device, a grinding part transverse sliding device and an arc-shaped gantry type adsorption type material frame. The invention belongs to the technical field of outer curved surface part high-precision grinding, and particularly relates to a variable-pressure type high-precision outer curved surface grinding device and a using method thereof. Air in a hollow cavity of the grinding base ring is heated by heat inevitably generated in the grinding process through the thermal expansion type non-metal grinding cavity bag assembly, and the non-metal semi-flexible grinding sand ring is further supported through expansion of the air in the hollow cavity of the grinding base ring; the base body of the flexible grinding wheel can be effectively prevented from becoming loose due to thermal expansion, and original harmful heat can be guided out through a proper channel; and according to the grinding head driving and feeding devices which are annularly and uniformly distributed, the angle of the torsion type grinding ring can be adjusted in a self-adaptive manner according to the appearance of the part.
Description
technical field [0001] The invention belongs to the technical field of high-precision grinding of outer curved surface parts, and specifically refers to a pressure-changing type high-precision outer curved surface grinding device and a use method thereof. Background technique [0002] High-precision grinding needs to improve the processing accuracy from many aspects. The grinding wheels used for grinding are generally divided into two types: rigid surface and flexible surface. The inside of the grinding wheel with flexible surface is often filled with sponge, etc., which has certain support and flexibility. material; compared with ordinary hard grinding wheels, flexible surface grinding wheels can better adapt to the surface shape of parts. Although the grinding efficiency is low, it can have a very favorable impact on the surface roughness and precision of the final product. However, the current The grinding device based on the flexible emery wheel still has the following p...
