Description
Technical field
The present invention relates to a kind of honing head, particularly the structure improved brake hub grinding head of one.
Background technology
Brake hubs is one of strength member on automobile, the cylindricity of this part inner surface (i.e. rubbing surface) requires higher, the endoporus of this part is general larger, the degree of depth is more shallow, belong to blind hole, with the honing head of ordinary construction to the honing of brake hubs inner surface, occur that oral area is large, the situation that bottom is little, can not meet the technical requirement of part.
Summary of the invention
In order to make up 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 is also by abundant grinding, ensure that the grinding accuracy of brake hubs blind hole.
The present invention in order to the technical scheme solving 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, regulate mandrel circumferencial direction to rotate and axially can resilient movement be positioned in overcoat, at least one sand stripe stand is positioned at outside overcoat, sleeve side wall is provided with a radial perforation, ejector pin activity is inserted in this perforation, ejector pin one end only peaks at and regulates mandrel lateral wall, the ejector pin other end presses closer in sand stripe stand one end madial wall, sand stripe stand lateral wall is installed with emery stick, described adjustment mandrel lateral wall is the conical surface of one end external diameter convergent, the sand stripe stand other end and overcoat lateral wall are articulated and connected, the concrete structure be articulated and connected is: overcoat one end lateral wall is provided with radial bar hole, sand stripe stand sidewall is provided with limited post, can slide along bar hole length direction in the bar hole that limited post vertically be able to be inserted in overcoat, the overcoat other end is provided with the groove of an opening towards overcoat one end, the sand stripe stand other end is inserted in this groove, the seamed edge that the sand stripe stand other end can have a common boundary around groove madial wall and open end revolves, the seamed edge that groove madial wall and open end have a common boundary forms jointed shaft, during use, honing head entirety is inserted in the blind hole of brake hubs, then mandrel axial feed is regulated, ejector pin is subject to regulating the only top of the conical surface of mandrel lateral wall and moving laterally, and then head on sand stripe stand one end and swing around articulated position laterally, when such honing head drives emery stick to rotate, emery stick lateral wall walk track and form the conical surface that one end external diameter is greater than other end external diameter, ensure that brake hubs is positioned at blind-hole bottom edge and also can be ground to, again because honing head axially-movable when grinding finally is withdrawn into beyond opening from brake hubs blind-hole bottom, in turn ensure that the cylindricity of brake hubs blind hole like this.
As a further improvement on the present invention, described adjustment mandrel lateral wall is single wimble structure, and regulate mandrel not stretch out overcoat in emery stick grinding process, stroke is little, is applicable to blind hole grinding.
As a further improvement on the present invention, the structure that the seamed edge that the described sand stripe stand other end can have a common boundary around groove madial wall and open end rotates is: form the other end inside the sand stripe stand other end gradually away from the conical surface of overcoat lateral wall, formed when sand stripe stand rotates 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, the axial end of this obtuse angle breach angle that also with it form outer openings be greater than interior side opening corresponding to overcoat slot opening end end face.
As a further improvement on the present invention, described ejector pin only peaks at and regulates the end wall of mandrel one end be and regulate the inclined-plane that outside mandrel, the conical surface tilts in the same way, ensures that ejector pin is being subject to moving axially smoothly when regulating mandrel only to push up, and prevents stuck phenomenon.
As a further improvement on the present invention, described ejector pin only peaks at and regulates the end wall of mandrel one end parallel with the conical surface outside mandrel.
Advantageous Effects of the present invention is: adjustment mandrel lateral wall of the present invention drives sand stripe stand that radial beat action occurs by ejector pin, carry out making honing head be cone structure when grinding, ensure that brake hubs blind-hole bottom edge also can by sufficient grinding, ensure that the cylindricity of brake hubs blind-hole bottom, brake hubs is more stablized in the course of the work durable.
