As the further improvement of the utility model, said adjusting axle lateral wall is single wimble structure, regulates axle and in the emery stick grinding process, does not stretch out overcoat, and stroke is little, is fit to the blind hole grinding.
Further improvement as the utility model; The structure that the said 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 reach in the bar hole that vertically is inserted in overcoat and can slide along the bar hole length direction, and the overcoat other end is provided with the groove of an opening towards an end, and 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.
Further improvement as the utility model; The structure of the seamed edge rotation that the said 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 let 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 the further improvement of the utility model, said sand stripe stand other end lateral wall is provided with an obtuse angle breach, the corresponding angle of outer openings greater than inside that also form with it with overcoat slot opening end end face of the axial end of this obtuse angle breach.
As the further improvement of the utility model, said ejector pin only peaks at the end wall of regulating axle one end and is and regulates the inclined-plane that the axle outside conical surface tilts in the same way, guarantees that ejector pin moves axially when axle is only pushed up receiving regulating smoothly, prevents stuck phenomenon.
As the further improvement of the utility model, it is parallel with the axle outside conical surface that said ejector pin only peaks at the end wall of regulating axle one end.
The useful technique effect of the utility model is: the adjusting axle lateral wall of the utility model drives sand stripe stand through ejector pin beat action radially takes place; 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.

The specific embodiment
Embodiment: a kind of structure improved brake hubs honing head, comprise overcoat 1, regulate axle 2, sand stripe stand 3, ejector pin 4 and emery stick 5, adjusting axle 2 circumferencial directions can rotate and axially can resilient movement be positioned in the overcoat 1; At least one sand stripe stand 3 is positioned at overcoat 1 outside, and overcoat 1 sidewall is provided with a radial perforation, and ejector pin 4 activities are inserted in this perforation; Ejector pin 4 one ends only peak at regulates axle 2 lateral walls, and ejector pin 4 other ends press closer in sand stripe stand 3 one end madial walls, are installed with emery stick 5 on sand stripe stand 3 lateral walls; Said adjusting axle 2 lateral walls are the conical surface of an end external diameter convergent; Sand stripe stand 3 other ends and overcoat 1 lateral wall are articulated and connected, and during use, honing head integral body is inserted in the blind hole of brake hubs; Regulate axle 2 axial feeds then; Ejector pin 4 receives the ending the top of the conical surface of regulating axle 2 lateral walls and moves laterally, and then heads on sand stripe stand 3 one ends laterally around the articulated position swing, when honing head drives emery stick 5 rotations like this; Emery stick 5 tracks that lateral wall is walked form the conical surface of an end external diameter greater than other end external diameter; Guaranteed that brake hubs is positioned at the blind-hole bottom edge and also can be ground to, because honing head axially-movable when grinding finally is withdrawn into beyond the opening from the brake hubs blind-hole bottom, guaranteed the cylindricity of brake hubs blind hole so again again.
