A kind of technical solution that the utility model uses in order to achieve the above-mentioned object of the invention are as follows: motorcycle pressure reducing valve mandrel use
Drilling tool, key are: the drilling tool includes grip slipper and locating piece, offers and positions along grip slipper X-direction
The sliding slot of Block- matching offers offer and the matched brill of drill bit with the matched core axle hole of mandrel, along Z-direction along the y axis
Hole slot, sliding slot, core axle hole and bore channel connect, and locating piece is inserted into sliding slot and by the locating slot of one side and inserting
Mandrel axis in core axle hole is flat to cooperatively form mandrel location structure, and mandrel pin hole preboring position is directed at bore channel upwards.
In the tool structure, sliding slot, core axle hole and bore channel intersect vertically and penetrate through, and keep locating piece end and mandrel axis flat
Portion cooperates positioning core axle, is aligned the preboring position of mandrel pin hole with bore channel upwards, realizes fast clamp, positioning core axle.
Further, for the ease of positioning core axle, locating slot adapts to the flat portion's design of mandrel axis, and locating slot is opened in along Y-direction
The top of locating piece forms chute wall and arc cell wall that X concaves, and the flat portion of mandrel axis is located in locating slot, axial slices
Fitting chute wall, periphery fitting arc cell wall, step surface, which are against on the Y-direction end face of positioning groove end, forms location structure.
Further, for the ease of the reset of locating piece, the locating slot lower section of the locating piece is blind to reset is offered along X
Hole resets in blind hole and is provided with reset spring.
Further, for the ease of automatic operation, the side X of grip slipper is provided with driving locating piece on end face in cunning
The linear drive apparatus slided in slot, reset spring are against the other side.
Further, the linear drive apparatus uses cylinder.
Further, for the ease of installing and processing, the other side X of grip slipper is provided with end cap on end face, resets bullet
Spring is against on end cap.
Further, for drilling operation, bore channel is the opening blind slot across mandrel pin hole.
The utility model has the following beneficial effects: the 1, utility model is by setting grip slipper and in three directions of grip slipper
Upper ingenious setting sliding slot, core axle hole and bore channel make locating piece by its locating slot quick and precisely positioning core axle, easy to operate,
Drilling difficulty and cost are reduced, efficiency and yield rate are improved.2, effect is further increased using driving cylinder and reset spring
Rate and operating accuracy.
