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
The present invention relates to a kind of honing head, particularly a kind of structure improved brake hub grinding head.
Background technology
Brake hubs is one of strength member on the automobile, this part is had relatively high expectations to the cylindricity of inner surface (being rubbing surface), the endoporus of this part is generally larger, the degree of depth is more shallow, belong to blind hole, use the honing head of ordinary construction to the honing of brake hubs inner surface, it is large oral area to occur, the situation that the bottom is little can not satisfy the specification requirement of part.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of structure improved brake hub grinding head, this structure improved brake hub grinding head can guarantee that brake hubs blind-hole bottom edge also by abundant grinding, guaranteed the grinding accuracy of brake hubs blind hole.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of structure improved brake hub grinding head, comprise overcoat, regulate mandrel, sand stripe stand, ejector pin and emery stick, adjusting mandrel circumferencial direction can rotate and axially can resilient movement be positioned in the overcoat, at least one sand stripe stand is positioned at the overcoat outside, sleeve side wall is provided with a radial perforation, the ejector pin activity is inserted in this perforation, ejector pin one end only peaks at regulates the mandrel lateral wall, the ejector pin other end presses closer in sand stripe stand one end madial wall, be installed with emery stick on the sand stripe stand lateral wall, described adjusting mandrel lateral wall is the conical surface of an end external diameter convergent, the sand stripe stand other end and overcoat lateral wall are articulated and connected, during use, honing head integral body is inserted in the blind hole of brake hubs, then regulate the mandrel axial feed, ejector pin is subject to regulating the ending the top of the conical surface of mandrel lateral wall and moves laterally, and then head on sand stripe stand one end and swing around articulated position laterally, when honing head drives the emery stick rotation like this, emery stick track that lateral wall is walked forms an end external diameter greater than the conical surface of other end external diameter, guaranteed that brake hubs is positioned at the blind-hole bottom edge and also can be ground to, again because honing head beyond axially-movable finally is withdrawn into opening from the brake hubs blind-hole bottom when grinding, has guaranteed so again the cylindricity of brake hubs blind hole.
As a further improvement on the present invention, described adjusting mandrel lateral wall is single wimble structure, regulates mandrel and do not stretch out overcoat in the emery stick grinding process, and stroke is little, is fit to the blind hole grinding.
As a further improvement on the present invention, the structure that the described sand stripe stand other end and overcoat lateral wall are articulated and connected is: overcoat one end lateral wall is provided with bar hole radially, the sand stripe stand sidewall is provided with limited post, limited post be able to vertically be inserted in the bar hole of overcoat and can slide along the bar hole length direction, the overcoat other end is provided with an opening towards the groove of an end, the sand stripe stand other end is inserted in this groove, the sand stripe stand other end can revolve around a seamed edge of groove madial wall and open end boundary, and the seamed edge that groove madial wall and open end have a common boundary forms jointed shaft.
As a further improvement on the present invention, the structure of the seamed edge rotation that the described sand stripe stand other end can have a common boundary around groove madial wall and open end is: the sand stripe stand other end is inboard to form the other end gradually away from the conical surface of overcoat lateral wall, when sand stripe stand rotates, form and allow bit architecture, prevent interference and collision, the seamed edge of sand stripe stand lateral wall and slot opening end in contact forms jointed shaft because of backstop action.
As a further improvement on the present invention, described sand stripe stand other end lateral wall is provided with an obtuse angle breach, and the axial end of this obtuse angle breach is corresponding with overcoat slot opening end end face and form with it outer openings greater than the angle of interior side opening.
As a further improvement on the present invention, described ejector pin only peaks at the end wall of regulating mandrel one end and is and the inclined-plane of regulating the mandrel outside conical surface and tilting in the same way, guarantees that ejector pin moves axially when mandrel only pushes up smoothly being subject to regulating, and prevents stuck phenomenon.
As a further improvement on the present invention, it is parallel with the mandrel outside conical surface that described ejector pin only peaks at the end wall of regulating mandrel one end.
Useful technique effect of the present invention is: adjusting mandrel lateral wall of the present invention drives sand stripe stand generation beat action radially by ejector pin, make honing head when grinding, be cone structure, guaranteed that brake hubs blind-hole bottom edge also can be by sufficient grinding, guaranteed the cylindricity of brake hubs blind-hole bottom, it is durable that brake hubs is more stablized in the course of the work.
