Further, described body offers through hole, in this through hole, be provided with a fairlead, described push rod can axially move
Dynamic in this fairlead.
The installation of slide block is preferably as follows mounting means：The lower end of described body is provided with pressing plate, and described slide block is limited to press
In space between plate and body lower surface and can move radially.
Preferably, the bottom of described push rod is provided with mounting seat, described roller can be rotatably arranged in this mounting seat
Compared with prior art, it is an advantage of the current invention that：In the workpiece grinding taper hole that cannot turn round, it is equipped with phase
Answer tapered wheel, the reducing processing of grinding hole can be realized by the device of this invention, solve emery wheel and adopt X-axis, Y-axis interpolation
The trajectory error problem that circular path causes；Clearance adjustment mechanism in the course of the work can be so permissible with automatic regulating gap
By break-in guide rail angle adjustment, change roller and slideway relative position, eliminate roller and slideway gap, so as to eliminate emery wheel
Along the play of grinding skin, theoretical according to error-correction model, can eliminate and be ground finished surface annular grinding vestige, improve and ground
Cut the surface quality on surface；Compared with plunge grinding processing mode, reduce the abrasion of emery wheel, thus reach improving grinding accuracy
Purpose.The present invention is not only rational in infrastructure, machining accuracy is high, and improves working (machining) efficiency and yield rate, solves and cannot turn round
Taper hole precision on workpiece patrols side grinding problem.
