Internal burr removing device for cylindrical chamber of hydraulic valve

Abstract

The invention relates to an internal burr removing device for a cylindrical chamber of a hydraulic valve. The internal burr removing device comprises a power device, and a base for performing connection to the power device, wherein fixing bolts are arranged on the base. The internal burr removing device further comprises a long grinding wheel base of which one end is mounted on the base and fixed by the fixing bolts, and the length of the end of the base can be adjusted by the fixing bolts; and a grinding wheel is fixed to the other end of the base.

Description

technical field [0001] The invention belongs to the field of mechanical processing, in particular to a deburring device used in a cylindrical cavity of a hydraulic valve. Background technique [0002] In the field of mechanical processing, before the final shape and size of the machined parts are completed, they are generally processed by various machine tools. However, this processing method will inevitably produce burrs, which cannot directly meet the requirements of the production process. glitch program. Usually deburring methods include manual method or mechanical rounding, chamfering, vibration, grinding and so on. However, these deburring methods have many disadvantages when processing deep cylindrical workpieces, especially for some cylindrical cavities that need to be sealed, because in the manual deburring process, especially during the grinding process, the file is forced Imbalance will cause frustration, which will cause air or oil leakage in these cavities tha...

Problems solved by technology

[0003] Aiming at the problem of deburring after mechanical processing, the existing technology proposes to use mechanical grinding tools to eliminate the burrs in the cylindrical cavity. This kind of technology does solve the problem of unbalanced manual operation, and realizes deburring through the high-speed rotation of the mechanically driven grinding tool. Purpose, but this type of file is the file with the same shape as the cylindrical cavity, but this type of grinding has the following defects, that is, this type of grinding tool must be in close contact with the workpiece to be processed when it is working, However, the removed burrs and scraps of the file are not easy to fall off, which affects the grinding efficiency. In order to facilitate the grinding of hard workpieces, a soft grinding wheel is used, and a hard grinding wheel is used for grinding soft material workpieces.

Not only that, this type of device also cannot realize grinding on the edge and inside of the cylindrical cavity at the same time
