On platform, with grinding wheel cylindrical or end face, workpiece circular arc face is ground by five-axle linkage.
Cylindrical grinder is ground, if Workpiece's Arc Radius exceedes machine tooling scope, can not be processed；If on same circumference
There is the part for being higher by circular arc, then circular arc can not be processed；When needing special emery wheel, because grinding wheel of external grinder is big, then emery wheel cost is high；
Normal condition lower grinding wheel can not control coaxially well when installing, if emery wheel can not be copied on lathe, grinding wheel cylindrical grinding circle
Roughness after arc is not fine.
Cutter and tool grinding machine copies formed grinding wheel straight-line feed rounding arc, and the radius that emery wheel can be ferreted out is restricted, and some emery wheels do not have also
Method is copied, such as skive.
Not only equipment investment is big for jig grinder, and emery wheel mill bar is thin, and when being ground high hard material, grinding force is big, easily folding
Disconnected mill bar, can not continue, or even cause security incident.
Numerical control tool grinder equipment investment is big, it is necessary to which open programming software is, it is necessary to the operating personnel that can be programmed, therefore adds
Work cost is high, also suffers from the limitation of clamping sometimes.

Embodiment
The technical solution of the utility model is further elaborated with reference to embodiment and accompanying drawing.
Embodiment 1
Present embodiments provide it is a kind of be ground arc surface servicing unit, it include bottom plate, rotating shaft, revoliving arm, first consolidate
Fixed set, threaded, the second fixed cover, bolt, thrust ring, screw rod and handwheel.
The bottom plate is fixed on platen, and workpieces processing is by clamping on revoliving arm, and the revoliving arm is by turning
Axle is rotatably connected and (is hinged) with the bottom plate, i.e., described revoliving arm can be around the axis of rotation.
First fixed cover is fixed on the revoliving arm, and the threaded is rotatably fixed to described first and fixed
In set, and the axis of the threaded is perpendicular to the revoliving arm, and the diameter parallel of the screwed hole on the threaded in
The revoliving arm.
In the present embodiment, first through hole is offered on the revoliving arm, along its week on the lateral wall of first fixed cover
It is located to one end (such as left end in Fig. 2) formed with flange, first fixed cover in the first through hole, the flange
With the revolution arm contact, and the flange is fixed on the revoliving arm by screw.
First fixed cover is hollow structure, one end (such as left end in Fig. 2) insertion of the threaded described the
In one fixed cover, and realize that by back-up ring the fixation of the left and right directions position of the threaded, such as the back-up ring pass through screw
One end that the threaded is located in first fixed cover is fixed on, and the diameter of the back-up ring is located at more than the threaded
Diameter in first fixed cover, so that the back-up ring is in contact with first fixed cover, and realize to the spiral shell
The fixation of the axial location of line pin.
Second fixed cover is fixed on the bottom plate, and the bolt is rotatably fixed to second fixed cover
It is interior, be fixed with thrust ring on the screw rod, one end of the screw rod passes through the hole of the bolt, and with the screw thread of the threaded
Hole coordinates, and the thrust ring is located in the groove of the bolt；That is, being fixed with first, nested structure is identical, and described second is solid
Fixed set is also hollow structure, and on the lateral wall of second fixed cover along its circumference formed with flange；Opened up on the bottom plate
