Detailed Description

The invention will be further explained with reference to the following figures and examples:

referring to fig. 1 to 4 show a brake pump shell anchor clamps for drilling for fasten brake pump shell 1 and be convenient for it and drill, including

bottom plate

2, 2 both sides of bottom plate are fixed with

riser

3, 3 tops of riser are fixed with a backup pad 4, bottom plate 2 is fixed with pull-down device, pull-down device includes pull rod 5 down, pull rod 5 is last to dismantle and be connected with pull plate 6 down, set up casing clearing hole and drill bit hole 7 of stepping down in the backup pad 4, the drill bit outside of hole 7 of stepping down still is fixed with casing outer fringe location boss 9.

When in use, the clamp for drilling the brake pump shell is fixed on a drilling machine, when the outer edge 8 of the brake pump shell needs to be drilled, an operator firstly penetrates the lower end of the brake pump shell 1 through the shell through hole on the supporting plate 4, the connecting hole below the shell penetrates the lower pull rod 5, and is positioned by a positioning boss 9 at the outer edge of the shell, the positioning boss 9 adopts a structure of enclosing three sides, when the brake pump housing 1 is positioned, the pull-down plate 6 is coupled to the pull-down rod 5, the pull-down device starts to pull the pull-down rod 5 downward, when the lower pull rod 5 moves downwards, the lower pull disc 6 is gradually clamped on the cylinder in the shell and tensions and positions the shell, and finally, the numerical control drilling machine starts to drill the shell, since the drill bit relief hole 7 is fixed to the support plate 4, the drill bit is not interfered when drilling.

Furthermore, the two sides of the vertical plate 3 are provided with extending parts 10 outwards, and the support plate 4 is detachably connected to the extending parts 10 through bolts and nuts. In order to make the utility model discloses can have more extensive suitability, wherein backup pad 4 passes through the bolt and nut detachable connects on the extension 10 of riser 3 both sides, when needing the casing of fixed different models promptly, directly change backup pad 4 can.
