Description
Technical field
The present invention relates to a kind of machining tool clamp, specifically a kind of frock for clamping thin-wall sleeve parts.
Background technology
The endoporus of the part of thin-wall sleeve class is finished in lathe, because cover parts wall thickness is small, in processing, by frock
When fixture accommodates, product itself can be made to deform；After machining, it is difficult to ensure that the precision of endoporus, causes the matter of product
Amount is unstable.
The content of the invention
The defect and part that the present invention exists when being used for existing frock clamp clamp thin-wall sleeve parts there is provided one kind
Frock, it is possible to reduce influence of the fixture to thin-wall sleeve class deformation of products, improve the machining accuracy of product, reduce to the phase of lathe
To required precision, so as to also reduce the cost of Product processing.
The present invention uses following technical scheme to solve technical problem：
A kind of frock for clamping thin-wall sleeve parts, it is characterised in that：Including being arranged on by hold-down bolt on lathe ring flange
Clamp body, the clamp body has a hollow endoporus, interior to embrace set provided with the elasticity for placing product, and the elasticity is embraced inside set top
Provided with support ring, it is connected in the middle of bottom by turnbuckle with the lathe pull bar through ring flange center；The support ring, elasticity
Embrace set and product gap between them coordinates, the radial clearance of described armful of set and product is less than between support ring and the radial direction for embracing set
Gap.
Further, the elasticity, which is embraced, is provided with mutual cooperation taper, the phase inside set tip exterior and clamp body top
The height of taper is mutually coordinated to be more than the thickness of support ring, less than the thickness of 2.5 times of support rings.
Further, the support ring and the radial fit gap for embracing set are 0.002-0.03mm, the support ring and production
Radial clearance is 3-10mm between product.
Further, the guiding step cooperated with the hollow endoporus of clamp body is provided with outside described armful of set lower end, be oriented to
The hollow endoporus of step and clamp body coordinates for gap.
Further, described armful of set is many valves fluting resilient sleeve, and product is placed in the endoporus for embracing set.
Further, jump-ring slot, jump ring are provided with provided with the step for placing support ring, step upper end inside described armful of set top
The jump ring of clamp support ring is provided with groove.
Further, described armful set lower end and clamp body hollow endoporus lower end for gap cooperation.
Further, described armful of set coordinates with ring flange for gap.
Further, the hollow endoporus of the clamp body is hollow cylindrical endoporus.
Further, described armful of set is many valves fluting cylindrical elastomeric set.
When assembling, first clamp body is fixed on ring flange by hold-down bolt, then is placed on embracing in clamp body,
It is fixed on by turnbuckle on lathe pull bar, support ring is placed in the upper surface step for embracing set, passes through the jump ring in jump-ring slot
By support ring clamp；Product is placed in and embraced in set endoporus, is tensed by lathe pull bar and embraces set, set and clamp body taper fit portion is embraced
Divide after laminating completely, embrace a set and deform, clamp product and support ring；Because the taper fit for embracing set and clamp body is highly more than
The thickness of support ring, less than the thickness of 2.5 times of support rings, and support ring has very high intensity hardness；Therefore support ring energy
It is enough to prevent an armful set from continuing to deform, so as to ensure that excessive deformation will not occur for product.
Compared with prior art, the invention provides a kind of special tooling of thin-wall sleeve parts, for the production of thin-wall sleeve class
Endoporus and the end face processing of product, the combination for embracing set and clamp body by elasticity can avoid deformation of products, improve product quality.Tool
Body is embodied in：1）Set is embraced by the support ring, elasticity and product gap between them coordinates and embraced the footpath of set and product
It is less than the setting of radial clearance of the support ring with embracing set to gap, it is ensured that frock is when work, effective product clamping,
And ensure that product is indeformable；Furthermore, the thickness of support ring is highly more than due to embracing the taper fit of set and clamp body, less than 2.5
The thickness of times support ring, and support ring has very high intensity hardness；Therefore support ring can prevent to embrace set continuation deformation, from
And excessive deformation will not be occurred by ensureing product；2）The outside cylinder lower end for embracing set sets guiding step, during an armful set is tensed,
Guide effect can be played, reduces numerical value of the endoporus equivalent to the circular runout of external diameter.
