Technical field
The present invention relates to machinery processing apparatus field, specially a kind of workpiece grinding subassembly.
Background technology
Workpiece generally requires precision feeding to control machining accuracy in grinding process.Vibration during due to grinding with
And reaction force is processed, feeding transmission system often bears larger load, and this easily produces shadow to its accuracy or service life
Ring.
The content of the invention
It is an object of the invention to provide a kind of workpiece grinding subassembly, for overcoming drawbacks described above of the prior art.
According to the workpiece grinding subassembly of the present invention, for being ground to workpiece, including Grinding wheel and for described
Workpiece carries out the pedestal of supporting feeding, and the left side of the pedestal is slideably supported with the workpiece clamp for clamping the workpiece
Tool, the work piece holder can to the left be promoted by Feed servo system bar and cause the workpiece against the Grinding wheel, the pedestal
On be also equipped with the fixed block that is passed through by the Feed servo system bar and feeding on the fixed block against component, institute
State feeding include being symmetricly set on above and below the Feed servo system bar both sides against component and interior end to be resisted against it is described enter
To the left arresting lever and right arresting lever on drive rod, the middle part of the left arresting lever and right arresting lever is articulated with the fixation
Block, wherein, the outer end of the left arresting lever and right arresting lever above and below the Feed servo system bar at every side of both sides 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,
Being oriented to of the left arresting lever and right arresting lever is inclined such that respective interior end is located at the left side of 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;Unblock magnet is installed in the middle part of the draw back plate to be used to being installed on the setting being arranged on the pedestal
Electromagnetic wire collar member on part coordinate to realize the driving of the rotation to the left arresting lever and right arresting lever so as to release it is described against.
In the device of the present invention, due to can be by the locking of left arresting lever and right arresting lever 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
The problem of.

Embodiment
With reference to Fig. 1-3, the present invention is described in detail.
With reference to Fig. 1-3, workpiece grinding subassembly, for being ground to workpiece 1, including grinds according to an embodiment of the invention
Wheel 9 and the pedestal 3 for the workpiece 1 support feeding are cut, the left side of the pedestal 3, which is slideably supported with, to be used for
The work piece holder 8 of the workpiece 1 is clamped, the work piece holder 8 can to the left be promoted by Feed servo system bar 7 and cause the workpiece
1 against the Grinding wheel 9, and the fixed block 5 that is passed through by the Feed servo system bar 7 is also equipped with the pedestal 3 and is arranged on
Feeding on the fixed block 5 is against component 6, and the feeding includes being symmetricly set on the Feed servo system bar 7 against component 6
Lower both sides 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, the left side is stopped
The middle part of lever 63 and right arresting lever 64 is articulated with the fixed block 5, wherein, in the Feed servo system bar, about 7 both sides
The outer end of the left arresting lever 63 and right arresting lever 64 at per side is hinged with push rod 62, the right-hand member of two push rods 62
Clamp region 620 is provided with to coordinate with same draw back plate 61, the draw back plate 61 passes through its mesopore 610 and the folder
The cooperation of the axle portion 621 of hardened structure 620 and allow push rod 62 to be moved up and down relative to the draw back plate 61;Wherein, the left side is stopped
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, thus,
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 is supported
By the Feed servo system bar 7;The middle part of the draw back plate 61 is provided with unblock magnet 612 to be arranged on the base with being installed on
The electromagnetic wire collar member 69 in riser 68 on seat 3 coordinates to realize that the rotation to the left arresting lever 63 and right arresting lever 64 is driven
It is dynamic so as to release it is described against.
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
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 is retreated.
Due to can be by the locking of left arresting lever and right arresting lever 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, can in the case of the overall spirit of the present invention and design is not departed from
To make the various modifications for above example.It is each fallen within protection scope of the present invention.The protection scheme of the present invention
It is defined by claims appended hereto.
