Brake hub honing head with improved structure

Abstract

The invention discloses a brake hub honing head with an improved structure. The brake hub honing head comprises a jacket, a regulating mandrel, at least one grinding stick holder, an ejector pin and a grinding stick, wherein the regulating mandrel can rotate in the circumferential direction, and can flexibly move and be located in the jacket in the axial direction; the grinding stick holder is arranged at the outer side of the jacket; a radial through hole is formed in the side wall of the jacket; the ejector pin is movably inserted in the through hole, the outer side wall of the regulating mandrel is pressed against by one end of the ejector pin, and the inner side wall of one end of the grinding stick holder is tightly pressed by the other end of the ejector pin; the grinding stick is fixedly arranged on the outer side wall of the grinding stick holder; the outer side wall of the regulating mandrel takes the shape of a conical surface, and the outer diameter of one end of the conical surface is gradually decreased; and the other end of the grinding stick holder is connected with the outer side wall of the jacket in a hinging way. According to the invention, the grinding stick holder is driven by the outer side wall of the regulating mandrel to make radial deflection motion through the ejector pin, and the honing head takes the shape of a conic structure during grinding, so that the sufficient grinding of the bottom end edge of a blind hole of a brake hub can be guaranteed, the cylindricity of the bottom end of the blind hole of the brake hub can be guaranteed, and the brake hub is enabled to be more stable and durable in the work process.

Description

technical field [0001] The invention relates to a honing head, in particular to a brake hub honing head with improved structure. Background technique [0002] The brake hub is one of the important parts of the car. This part has a high requirement for the cylindricity of the inner surface (that is, the friction surface). The inner hole of the part is generally larger and shallower. It is a blind hole. When the head hones the inner surface of the brake hub, the mouth is large and the bottom is small, which cannot meet the technical requirements of the parts. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a brake hub honing head with improved structure. The brake hub honing head with improved structure can ensure that the bottom edge of the brake hub blind hole is also fully ground, ensuring the grinding of the brake hub blind hole. Cutting accuracy. [0004] The technical solution adopted by the present in...
