The middle part of left arresting lever and right arresting lever on Feed servo system bar, the left arresting lever and right arresting lever is articulated with the fixation
Block, wherein, the outer end of described left arresting lever and right arresting lever at every side of the upper and lower both sides of Feed servo system bar with
Push rod is hinged, and the right-hand member of two push rods is provided with clamp region and is used to coordinate with same draw back plate, and the draw back plate leads to
Cross the cooperating for axle portion of its mesopore and the clamp region and allow push rod to be moved up and down relative to the draw back plate;Wherein,
The left arresting lever and right arresting lever 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 of extension spring that is arranged between the clamp region and the fixed block so that the interior end is against institute
State Feed servo system bar;Be provided with the middle part of the draw back plate unblock magnet to be installed on the setting that is arranged on the pedestal
Electromagnetic wire collar member on part coordinate with the rotation for realizing to the left arresting lever and right arresting lever drive so as to release it is described against,
A push rod is provided with the top of the riser, the push rod upper end is provided with a dust excluding plate, the left end of the dust excluding plate and institute
State fixed block to be fixedly connected, the top end face of the push rod is flushed with the top end face of the fixed block, the dust excluding plate is used to prevent
Dust drops on the part being deposited between the fixed block and the riser.
In device of the invention, due to the right arresting lever of locking can be by left arresting lever and to(for) Feed servo system, therefore
Machining load can be avoided to be directly delivered to feed drive system.And can realize what stop was locked by electromagnetic drive mechanism
Unblock, so that feed system carries out withdrawal action.Whole device is reliable, stabilized structure, can effectively solve the problem that prior art
Problem.

Specific embodiment
With reference to Fig. 1-3, the present invention is described in detail.
With reference to Fig. 1-3, workpiece grinding subassembly dust-proof according to an embodiment of the invention, for being ground to workpiece 1, is wrapped
Grinding wheel 9 and the pedestal 3 for the workpiece 1 support feeding are included, the left side of the pedestal 3 is slideably supported with
Work piece holder 8 for clamping the workpiece 1, the work piece holder 8 can to the left be promoted by Feed servo system bar 7 and caused described
Workpiece 1 is also equipped with fixed block 5 and the peace passed through by the Feed servo system bar 7 against the Grinding wheel 9 on 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
Bar both sides and interior end is used to the left arresting lever 63 and right arresting lever 64 that are resisted against on the Feed servo system bar 7 about 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 two about 7
The outer end of described 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-hand member is provided with clamp region 620 to coordinate with same draw back plate 61, and the draw back plate 61 passes through its mesopore 610 and institute
State the cooperation of the axle portion 621 of clamp region 620 and allow push rod 62 to be moved up and down relative to the draw back plate 61;Wherein, it is 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 of extension spring 67 that is 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 provided with unblock magnet 612 be used to be installed on be arranged on it is described
The electromagnetic wire collar member 69 in riser 68 on pedestal 3 coordinates to realize the rotation to the left arresting lever 63 and right arresting lever 64
Drive described against the top of the riser 68 is provided with a push rod 70, and the upper end of the push rod 70 is provided with one to release
Dust excluding plate 71, the left end of the dust excluding plate 71 is fixedly connected with the fixed block 5, the top end face of the push rod 70 and the fixation
The top end face of block 5 is flushed, the dust excluding plate 71 be used to prevent dust drop be deposited in the fixed block 5 and the riser 68 it
Between part on, so as to ensure the normal operation of the part between the fixed block 5 and the riser 68.
Exemplarily or valuably, wherein, the Feed servo system bar 7 be provided with radially enlarged butting section be used to it is described
Interior end against.
Exemplarily or valuably, wherein, the Feed servo system bar 7 is by screw drive.
Exemplarily or valuably, wherein, the interior end and the Feed servo system bar 7 against for rub against so as to
By applying suitably to avoid the work piece holder 8 described in grinding process together with the workpiece 1 relative to described against pressure
Grinding wheel 9 is retreated.
Due to the right arresting lever of locking can be by left arresting lever and to(for) Feed servo system, therefore, it is possible to avoid machining load
It is directly delivered to feed drive system.And the unblock that stop is locked can be realized by electromagnetic drive mechanism, it is to feed
System carries out withdrawal action.Whole device is reliable, stabilized structure, can effectively solve the problem that problem of the prior art.
Those skilled in the art can be clear and definite, in the case of overall spirit of the invention and design is not departed from, can
To make the various modifications for above example.It is each fallen within protection scope of the present invention.Protection scheme of the invention
It is defined by claims appended hereto.
