There is nut, nut is fixedly connected with clamping device 120.It can be with mobile clamping device 120, to change by rotating threaded shaft 160
The radius of product circular slab.
The working principle of circle of contact edging machine is as follows: one piece of plank is placed in the first clamping element 122 and the second clamping element 124
Between, and start the cylinder clamping on clamping device 120.Then, the cylinder connecting with the second shaft 150 is started, so that second
Shaft 150 is close to first rotating shaft 145, so that the first blade and the second blade are abutted with plank.Finally, will be from by shift fork 144
It closes wheel 143 to stir close to sprocket wheel 142, and is caught in the protrusion 1432 of castle wheel 143 on sprocket wheel 142 in the groove of connecting cylinder；It opens
Dynamic driving device 140, speed reducer are rotated by the sprocket wheel 142 on chain-driving main shaft 141, and connection is driven by castle wheel 143
Main shaft 141 rotates, and main shaft 141 drives cutting flange fixing installation 130 to rotate.At this point, plank is cut into circular slab by cutter 134, second
Flanging wheel 1324 presses plank in the groove such as the first flanging wheel 1322, to extrude groove at the edge of circular slab.Work as power failure
When, castle wheel 143 is stirred far from sprocket wheel 142 by shift fork 144, sprocket wheel 142 is disconnected with castle wheel 143.Pass through shake
The handle of 145 end of first rotating shaft drives first gear 1452 to rotate, to drive 141 turns of main shaft by first gear 1452
It is dynamic.Due to, sprocket wheel 142 is connect with main shaft 141 by bearing, so when main shaft 141 rotation not will drive speed reducer rotation；
So that swinging handle is relatively labor-saving.
It should be noted that in other embodiments, second gear 1412 can also be connect by bearing with main shaft 141,
At this point, castle wheel 143 is towards being provided with protrusion 1432 in the one side of second gear 1412, second gear 1412 be correspondingly arranged on
Matched groove；By slip clutch wheel 143, connection or the company of disengaging of castle wheel 143 and second gear 1412 may be implemented
It connects；Or in other embodiments, such as Fig. 1, in order to realize the second shaft 150 relative to main shaft 141 far from or close to movement,
It can also be threadedly coupled by lead screw with rack 110 using by the second shaft 150, the second shaft of rotational lead screw 150 can phase
It is mobile for rack 110；Or the clamping in order to realize clamping device 120, it can also be by the first clamping element using lead screw and folder
Other components of tight device are threadedly coupled, to make the first clamping element move relative to the second clamping element by rotating threaded shaft.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for this field
For technical staff, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
