Slot 85 is detachably connected.As shown in figure 16, when workpiece 1 to be processed is truncated cone-shaped structure, pass through the groove of first rotating shaft 83
At this moment the fixation that workpiece 1 consolidates can not be installed a clamping piece 71 by 85 in the second shaft 713, clamping piece 71 passes through
Second shaft 713 is connect with the groove 85 of first rotating shaft 83, is caught in realization first rotating shaft 83 and second in aperture 86 by pin 714
The fixation of shaft 713；It is gripped in this way, the bottom and top of the workpiece 1 of truncated cone-shaped structure all pass through clamping piece 71.
As shown in figure 14, it is the structural schematic diagram of third bracket 721 and third motor 72, is additionally provided on third bracket 721
Load-bearing cabinet 722, third motor 72 are connect by shaft coupling 723 with the third shaft in load-bearing cabinet 722, third shaft and the
The connection of two shafts 713；Load-bearing cabinet 722 is set to the bottom of clamping piece 71.It is arranged between clamping piece 71 and third motor 72 and holds
Loaded van body 722, avoid workpiece 1 prevent on clamping piece 71 after, gravity is all applied on third motor 72, is caused to third
The damage of motor 72；Load-bearing cabinet 722, which is arranged, also can effectively increase the gravity that clamping piece 71 can bear.
The working principle of the present apparatus:
The lower part of polished conical workpieces 1 is fixed by clamping piece 71, at the top of the groove 85 that top passes through first rotating shaft 83,
It is being set up between clamping piece 71 and first rotating shaft 83 tightly of workpiece 1；If truncated cone-shaped workpiece 1, then at first rotating shaft 83
One clamping piece 71 is also installed.Third hydraulic cylinder 81 can increase by upper and lower movement or reduce adding to workpiece 1
Holding force, simultaneously because third hydraulic cylinder 81 is movable, this can the workpiece 1 to different height carry out aid fixation.Clamping piece
71 can also 1 bottom of workpiece to different-diameter be fixed；First clamping device 7 and the second clamping device 8 are completed to workpiece 1
Fixation.Clamping piece 71 is connect by the second shaft 713 with third motor 72 simultaneously, drives clamping piece 71 by third motor 72
Rotation, while first rotating shaft 83 and second bearing 84 are rotatablely connected, this guarantees third motors 72 to drive workpiece 1 to do by axis
When rotary motion, second shaft 713 on 1 top of workpiece is also making rotating motion.With the above arrangement, can complete to different straight
Diameter and different height, i.e., the fixation of the conical workpieces 1 of different tapers.And guarantee to make work by third motor 72 in cabinet
Part 1 makes rotating motion along central axis.
In order to keep polishing machine disk and the inclined-plane of workpiece 1 of polishing mechanism 3 perpendicular, pass through first hydraulic cylinder 61 and
Two hydraulic cylinders 62 move up and down and the horizontal movement of horizontal sliding table, adjust to suitable distance and enable to first support 51 and circle
The bus of taper work 1 keeps vertical, while guaranteeing to keep suitable distance between polishing mechanism 3 and workpiece to be processed 1.And it throws
Ray machine structure 3 is vertically connected on together with oblique slide unit 52, is sheathed on oblique slide unit 52, can be moved back and forth on oblique slide unit 52.This
It ensures that polishing machine disk and 1 inclined-plane of workpiece are perpendicular, is moved back and forth by polishing mechanism 3 along oblique slide unit 52, Yi Jigong
There are also the movements of polishing machine itself for part 1 itself rotary motion, so that it may complete to inclined-plane can polishing area polishing.
Obviously, the above embodiment of the present invention be only to clearly illustrate example of the present invention, and not be pair
The restriction of embodiments of the present invention.For those of ordinary skill in the art, may be used also on the basis of the above description
To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.It is all this
Made any modifications, equivalent replacements, and improvements etc., should be included in the claims in the present invention within the spirit and principle of invention
