Abstract
The utility model provides a prong class for part screw rod from centring means, includes: drive screw, knurled nut, cylindric lock, threaded bush, driven screw, gland nut, support, drive screw's flat department of lower face milling and driven screw upper end fluting department match, driven screw and threaded bush cooperate, and threaded bush installs in the locating hole of support, threaded bush compresses tightly in the support through gland nut, the cylindric lock is installed on knurled nut. The utility model discloses compact structure can hide oneself in the prong of part, reduces frock clamp's occupation space. Through driving one of them screw rod, realized the centering location simultaneously and to the support at prong position, it is very practical to prong class part, with the better assurance work piece required precision of general processing method looks specific energy. Realize to the location of part with the stretching, when loosening the process, corresponding need are turned round tightly and are loosened knurled nut can.
Description
Technical field
The utility model belongs to machining frock technical field, is related to a kind of screw rod Self-centering device, more particularly to one
Plant prong class part screw rod Self-centering device.
Background technology
It is well known that when prong class part is processed, the prong position of prong class part is generally to other datum levels or base
Quasi- hole has centering to require, and prong class part prong position because self structure form often rigidity it is poor, work in-process warp
Can often vibrate, cause the processing dimension of part and precision to be affected.This is accomplished by a kind of prong that both can guarantee that part
Place's work in-process is indeformable, and the Self-centering device of part prong centering requirement can be met again.Existing Self-centering device structure
Greatly, frock clamp overall structure is caused also than larger.Therefore, a kind of compact conformation, easy to operate simple self-centering dress are developed
It is completely necessary to put.
Utility model content
The purpose of this utility model is to provide a kind of prong class part screw rod Self-centering device, and the device can be preferably
Ensure that prong class part prong position does not deform in machining, it is ensured that the symmetry requirement at prong.
To realize as above purpose, the technical solution adopted in the utility model is：A kind of prong class part screw rod self-centering
Device, including：Drive screw, knurled nut, straight pin, screw-thread bush, driven screw, clamp nut, bearing；Drive screw
The lower flat place of end mill is engaged with the fluting of driven screw upper end；Driven screw is engaged with screw-thread bush, and screw-thread bush is arranged on
In the location hole of bearing；Screw-thread bush is pressed in bearing by clamp nut；Straight pin is arranged on knurled nut.
Due to using technical scheme as described above, the utility model has following superiority：The utility model structure is tight
Gather, can hide oneself in the prong of part, reduce taking up room for frock clamp.By driving one of screw rod, while realizing
Centering positioning and the support to prong position, it is for prong class part very useful, can be more compared with general processing method
Good guarantee workpiece accuracy requirement.When realizing positioning and stretching to part, loosening process, corresponding need are tightened and loosened
Knurled nut.
Brief description of the drawings
Fig. 1 is a kind of structural representation of prong class part screw rod Self-centering device of the utility model.
Specific embodiment
The utility model will be further described below in conjunction with the accompanying drawings.As shown in figure 1, a kind of prong class part screw rod
Self-centering device, including：Drive screw 1, knurled nut 2, straight pin 3, screw-thread bush 4, driven screw 5, clamp nut 6, branch
Seat 7；Wherein, the flat place of lower end mill of drive screw 1 is engaged with the upper end fluting of driven screw 5；Driven screw 5 and screw-thread bush
4 are engaged, and screw-thread bush 4 is arranged in the location hole of bearing 7；Screw-thread bush 4 is pressed in bearing 7 by clamp nut 6；Circle
Pin 3 is arranged on knurled nut 2.
When prong class part 10 is placed in chuck body 9, by the hexagon-headed bolt 8 in chuck body 9 and positioning
Prong class part 10 is positioned placement by block 11, operates drive screw 1 to drive driven screw 5 by turning clockwise straight pin 3
Moved to opposite direction, drive screw 1 and driven screw 5 are ejected and complete self-centering positioning simultaneously, and stretching prong class part 10
Prong position, now prong class part 10 depart under the movement of the screw rod of Self-centering device as the turret head spiral shell of Auxiliary support
Bolt 8, completes self-centering positioning, while also support part.Then will upwards be screwed out as the hexagon-headed bolt 8 of Auxiliary support again
Support prong class part 10 can start processing.
After the completion of processing of prong class part 10, rotate counterclockwise straight pin 3 come operate drive screw 1 drive driven screw
5 are moved to opposite direction, and drive screw 1 and driven screw 5 are retracted and can be taken off workpiece simultaneously.
The utility model can hide oneself in the prong of part, reduce taking up room for frock clamp.By driving wherein one
Individual screw rod, while centering positioning and the support to prong position are realized, it is very useful for prong class part.
