Specific embodiment
Below with reference to Fig. 1-3, the present invention is described in detail.
In conjunction with Fig. 1-3, the dust-proof workpiece grinding subassembly of embodiment according to the present invention is wrapped for being ground to workpiece 1
Grinding wheel 9 and the pedestal 3 for carrying out bearing feeding to the workpiece 1 are included, the left side of the pedestal 3 is slideably supported with
For clamping the work piece holder 8 of the workpiece 1, the work piece holder 8 can be pushed to the left by Feed servo system bar 7 and be made described
Workpiece 1 is also equipped with the fixed block 5 passed through by the Feed servo system bar 7 and is pacified on the Grinding wheel 9, the pedestal 3
Against component 6, the feeding includes being symmetricly set on the Feed servo system against component 6 for feeding on the fixed block 5
About 7 two sides of bar and interior end is to the left arresting lever 63 and right arresting lever 64 that are resisted against on the Feed servo system bar 7, it is described
The middle part of left arresting lever 63 and right arresting lever 64 is articulated with the fixed block 5, wherein in the Feed servo system bar about 7 two
The outer end of the left arresting lever 63 and right arresting lever 64 at every side of side is hinged with push rod 62, two push rods 62
Right end is provided with clamp region 620 to cooperate with same draw back plate 61, and the draw back plate 61 passes through its mesopore 610 and institute
It states the cooperation of the axle portion 621 of clamp region 620 and push rod 62 is allowed to move up and down relative to the draw back plate 61;Wherein, described
Left arresting lever 63 and right arresting lever 64 are oriented to the left side for being inclined such that respective interior end is located at corresponding outer end, by
This, by the effect for the extension spring 67 being arranged between the clamp region 620 and the fixed block 5 so that the interior end
Against the Feed servo system bar 7;The middle part of the draw back plate 61 be equipped with unlock magnet 612 to be installed on be arranged described
Electromagnetic wire collar member 69 in riser 68 on pedestal 3 cooperates to realize the rotation to the left arresting lever 63 and right arresting lever 64
Drive so as to release the Feed servo system bar upper and lower sides and the left arresting lever 63 and right arresting lever 64 against the riser
68 top is provided with a mandril 70, and 70 upper end of mandril is provided with a dust excluding plate 71, the left end of the dust excluding plate 71 and institute
It states fixed block 5 to be fixedly connected, the top end face of the mandril 70 is flushed with the top end face of the fixed block 5, and the dust excluding plate 71 is used
On the component being deposited between the fixed block 5 and the riser 68 with preventing dust from falling, to guarantee the fixed block 5
The normal operation of component between the riser 68.
Illustratively or valuably, wherein the Feed servo system bar 7 be provided with radially enlarged butting section to it is described
Interior end against.
Illustratively or valuably, wherein the Feed servo system bar 7 is by screw drive.
Illustratively or valuably, wherein the interior end and the Feed servo system bar 7 against for rub against so as to
Suitably avoid the work piece holder 8 described in grinding process together with the workpiece 1 relative to described against pressure by applying
Grinding wheel 9 retreats.
Due to can the right arresting lever of locking by left arresting lever and to(for) Feed servo system, can be avoided machining load
It is directly delivered to feed drive system.And can be realized the unlock of stop locking by electromagnetic drive mechanism, it is to feed
System carries out withdrawal movement.Whole device is reliable for operation, and stabilized structure can effectively solve the problem that problem of the prior art.
Those skilled in the art can define, can in the case of not departing from overall spirit of the invention and design
