Patrol the radial feeding device of side grinding, it is characterised in that including
Body；
Push rod, body relatively above-mentioned can move axially under motor driving；
Idler wheel is set to the bottom end of aforementioned push rod；And
Sliding block, opposite body can move radially on aforementioned body and under the driving of idler wheel, be equipped with and become in the sliding block
Have to sliding rail, on the deflecting sliding rail and coordinates the oblique guide slot moved radially with movable slider with aforementioned roller；The cunning
Block is equipped with the clearance adjustment mechanism that can eliminate idler wheel and oblique guide slot gap.
Further, one end of the deflecting sliding rail can be rotatably arranged on sliding block, and the other end is equipped with the gap and adjusts
Mechanism, the clearance adjustment mechanism are a butterfly spring piece, which is fixed on sliding block, the upper surface of the other end
It offsets with the lower face of deflecting sliding rail.
Preferably, one end of the butterfly spring piece passes through on the lower face of screw setting and sliding block.It is simple in structure,
It is easy to set up.
Further, through-hole is offered on the body, a guide sleeve is equipped in the through-hole, the push rod can be moved axially
Dynamic is set in the guide sleeve.
The preferably following mounting means of the installation of sliding block：The lower end of the body is equipped with pressing plate, and the sliding block is limited to press
In space between plate and body lower face and it can move radially.
Preferably, the bottom end of the push rod is equipped with mounting base, the idler wheel can be rotatably arranged in the mounting base
Compared with the prior art, the advantages of the present invention are as follows：In the workpiece grinding taper hole that can not be turned round, it is equipped with phase
Tapered wheel is answered, grinding hole reducing processing can be realized by the device of this invention, solves grinding wheel using X-axis, Y-axis interpolation
Trajectory error problem caused by circular path；Clearance adjustment mechanism during the work time can be with automatic regulating gap, in this way can be with
It is adjusted by deflecting guide rail angle, changes idler wheel and slideway relative position, idler wheel and slideway gap are eliminated, so as to eliminate grinding wheel
Ground finished surface annular grinding trace can be eliminated according to error-correction model theory along the play of grinding skin, raising is ground
Cut the surface quality on surface；Compared with plunge grinding processing method, the abrasion of grinding wheel is reduced, grinding accuracy is improved to reach
Purpose.The present invention is not only reasonable for structure, high precision machining, but also improves processing efficiency and yield rate, and solving can not turn round
Taper hole precision on workpiece patrols side grinding problem.
