Technical field

The present invention relates to vertical machining centre technical field more particularly to a kind of high-precision hole location grinding toolings.

Background technique

Certain robotic part hole location and pore size required precision are high, using high precision numerical control jig grinder process unit price Valuableness, processing efficiency is low, and when conventionally employed high precision numerical control jig grinder is processed, needing after processing to part will be on its main shaft Bistrique is removed and replaces with that detector is to the hole that it is processed and hole inner wall detects, and surveys online in usual vertical machining centre The measurement that amount uses is placed in tool magazine, and in measurement, tool changing instruction calls gauge head to be detected, further according to the deviation adjusting depth of cut. Due to second of dress knife error, pore size precision of the correspondingly-sized precision within 5 microns influences big；If the hole in piece part of processing is It is undesirable, and head must be will test remove and replace with bistrique again and be processed again, then repeat above-mentioned replacement detection Head detect-changes the step of bistrique processing, until reach the state of meeting the requirements, the step of replacement detector repeatedly, cutter Increase cumulative errors.

To the greatest extent in this, the present invention proposes high accurate hole that is a kind of economic and can reaching high-precision hole location and pore size processing request Position grinding tooling.

Summary of the invention

It is an object of the invention to overcome the deficiencies in the prior art, adapt to reality and need, provide a kind of novel in structural design, It can solve the problems, such as to bring the high-precision hole location grinding tooling of error in mounting position because of replacement bistrique.

In order to achieve the object of the present invention, the technical scheme adopted by the invention is as follows:

A kind of high-precision hole location grinding tooling is designed, including fixing seat, the vertical processing of the high-precision high-speed with main shaft Center, spindle nose are equipped with bistrique；The fixing seat is fixed on the spindle box side of main shaft, and the top of the fixing seat is fixed One cylinder is installed, the telescopic shaft end of cylinder is fixed with a detector, and the detector can be by the flexible axially downwardly extending of cylinder Out or it is retracted to above main shaft.

The fixing seat bottom is equipped with a rectangular frame, and the telescopic shaft end of cylinder is fixed with one in the " [connecting plate of " shape Part, the top plate of attaching plate elements are fixed on telescopic shaft end, and the lower part plate suqare of attaching plate elements is less than the rectangular frame and can Across the rectangular frame, the detector is installed in the lower panel of attaching plate elements by detecting headstock；The rectangular frame A closed plate is hinged in a side of lower section, the closing plate suqare matches with the rectangular frame opening area and can be by institute Rectangular frame closing is stated, is fixedly connected with the upper connecting rod extended downwardly in the lower panel of the attaching plate elements, the closed plate Lower pull rod is hinged on movable end inner wall, the lower end of the other end and the upper connecting rod of the lower pull rod is hinged, when described flexible When withdrawing in axial direction, the detector is drawn back into above rectangular frame, and the upper connecting rod is upward and the lower pull rod is pulled to promote Make closed plate around hinge joint rotate upwards after by rectangular frame closure of openings.

It further include by the closed covering closing plate of the telescopic shaft, the lower end of covering closing plate is connect with rectangular frame, and works as institute When stating closed plate and closing the rectangular frame, the enclosed region of covering closing plate constitutes closed area and to detection head protection.

It is fixed with sliding block on the lateral wall of the attaching plate elements, sliding rail, the cunning are installed on the inner wall of the fixing seat Block is located on the sliding rail and moves along sliding rail.

Two middle side parts of the sliding rail are recessed inwardly, and the sliding block is equipped with sliding slot, and the end of sliding slot two sidewalls is equipped with phase To the convex block of extension, the convex block and the matching grooves are described convex when the sliding block is buckled on the sliding rail by sliding slot Block is located in the groove and the sliding block is limited on the sliding rail.

The beneficial effects of the present invention are:

High-precision hole location grinding tooling of the invention is implemented using high-precision high-speed vertical machining centre, first its The bistrique of high-precision high-speed vertical machining centre main shaft end can device to hole carry out grinding, the detector of its side can be stretched after processing Out and to hole location detecting, while while detecting, does not need with bistrique, and then high-precision high-speed vertical machining centre is detected according to detector Deviation size adjust automatically grinding and feeding amount reduces installation error of cutter.
