Abstract
The utility model discloses a fixture for thin-wall case processing. The fixture for thin-wall case processing comprises a tool mandrel, a positioning mechanism, a spacer sleeve and nuts. The tool mandrel is sheathed with the thin-wall case, the inner of the tool mandrel is provided with a central hole, and one end of the tool mandrel is provided with convex steps. The positioning mechanism is sheathed with the tool mandrel, and the thin-wall case to be processed is fixed. A plurality of spacer sleeves are sheathed with the tool mandrel and fixed by the nuts. With the spacer sleeves on both sides, the clamping and positioning of the whole thin-wall case are achieved, and the deformation in the process is avoided. The fixture for thin-wall case processing has the advantages that the stability of process quality is guaranteed, the structure is simple, and the processing and application are convenient and the like.
Description
Technical field
The utility model relates to anchor clamps, more particularly, relates to a kind of thin-wall sleeve fixture for processing.
Background technology
In the machinery support part, be applied to many thin-wall sleeve parts.This type of part is little because lightweight, material consume, cost is low, easy accessibility is widely used, still the yielding problem of ubiquity in turning processing.
At present, the anchor clamps of processing thin-walled cover have a variety of, and common is following two kinds:
1, for adopting scroll chuck as shown in Figure 1, on general three-jaw claw 1, weld respectively fan-shaped soft pawl 2, then the soft pawl 2 after the welding is carried out precision turning, make the internal diameter of soft pawl 2 and the outside dimension of part to be processed equate coaxial with the axis of rotation of lathe spindle.But because thin-wall sleeve 3 walls are thin, tend to when clamping thin-wall sleeve 3 folder distortion, the claw place is projecting inward to the hole, stock removal is larger, and remainder is less, unclamp claw 1 after; thin-wall sleeve 3 walls rebound to original shape, make the hole that grinds be comparatively significantly triangle, can not satisfy the size and dimension requirement in hole.
2, for adopting the sleeve 4 that cracks as shown in Figure 2, process in advance the elasticity sleeve 4 that cracks preferably, then thin-wall sleeve 3 is bumped in the sleeve 4 that cracks and clamps.Can evenly hold thin-wall sleeve 3 rear turning inner holes tightly.The employing sleeve 4 that cracks is clamped thin-wall sleeve 3 cylindricalo grinding endoporus, and grinding finds that by check the hole is irregular.Its reason is that the circularity of sleeve before opening of cracking is fine, the endoporus that overlaps behind the opening is irregular circle; be the circle of rule after the thin-wall sleeve 3 cylindricals corase grind; thin-wall sleeve 3 is packed into crack behind the sleeve; owing to thin-wall sleeve 3 wall thickness (2mm) much smaller than the sleeve wall thickness (5mm) that cracks, deformation occurs to adapt to the shape of the sleeve hole that cracks in thin-wall sleeve 3 under pressure.When external force clamps thin-wall sleeve 3, because the disappearance of the sleeve openings part material that cracks, the sleeve endoporus that cracks will be out of shape to opening portion, and the sleeve endoporus that causes cracking is not round, directly affects the shape of thin-wall sleeve 3 under clamped condition.Thin-wall sleeve 3 inner hole grinding under this state is also measured and can be obtained good circularity, but takes out thin-wall sleeve 3 rear measurements, finds that thin-wall sleeve 3 strain occurred and caused circularity and the non-constant of precision in hole, therefore necessary this kind installation way that changes.
The utility model content
For the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of thin-wall sleeve fixture for processing, can avoid deforming in thin-wall sleeve processing.
For achieving the above object, the utility model adopts following technical scheme:
This thin-wall sleeve fixture for processing comprises frock axle, detent mechanism, spacer sleeve and nut, the frock axle is in order to sheathed thin-wall sleeve, its inside has centre bore, one end is provided with the boss rank, detent mechanism is sheathed on the frock axle, in order to thin-wall sleeve to be processed is fixed, several spacer sleeves are sheathed on the frock axle and by nut and are fixed.
Described detent mechanism comprises a pair of positioning sleeve, and a positioning sleeve and boss rank offset, and another positioning sleeve and spacer sleeve offset, middle sandwiched thin-wall sleeve.
Be equipped with the concave station rank suitable with the thin-wall sleeve outer rim on the inboard outer rim on the described positioning sleeve.
Described nut links to each other by screw thread with the frock axle.
In technique scheme, thin-wall sleeve fixture for processing of the present utility model comprises frock axle, detent mechanism, spacer sleeve and nut, the frock axle is in order to sheathed thin-wall sleeve, its inside has centre bore, one end is provided with the boss rank, detent mechanism is sheathed on the frock axle, and in order to thin-wall sleeve to be processed is fixed, several spacer sleeves are sheathed on the frock axle and by nut and are fixed.Positioning sleeve by both sides can carry out clamping and positioning to whole thin-wall sleeve, avoids its work in-process to avoid deforming, and guarantees the stable of crudy, has simple in structure, processing and the advantage such as easy to use.
Description of drawings
Fig. 1 is the use view of the fan-shaped soft claw of prior art;
Fig. 2 is the use view of the sleeve that cracks of prior art;
Fig. 3 is the use view of thin-wall sleeve fixture for processing of the present utility model.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also shown in Figure 3, thin-wall sleeve fixture for processing of the present utility model comprises frock axle 5, detent mechanism, spacer sleeve 6 and nut 7, frock axle 5 is in order to sheathed thin-wall sleeve 3, centre bore 8 is opened in its inside, and an end is provided with boss rank 9, detent mechanism is sheathed on the frock axle 5, and in order to thin-wall sleeve to be processed 3 is fixed, several spacer sleeves 6 are sheathed on the frock axle 5 and by nut 7 and are fixed.Described detent mechanism comprises that a pair of positioning sleeve 10, one positioning sleeves and boss rank 9 offset, and another positioning sleeve and spacer sleeve 6 offset, middle sandwiched thin-wall sleeve 3.And be equipped with the concave station rank suitable with thin-wall sleeve 3 outer rims on the inboard outer rim on the described positioning sleeve, in order to just in time to clamp thin-wall sleeve to be processed 3.And described nut 7 links to each other by screw thread with frock axle 5, can detent mechanism, thin-wall sleeve 3, spacer sleeve 6 is fixing successively by nut 7.
During use, be set in successively on the frock axle 5 with left positioner cover, thin-wall sleeve 3 to be processed, right positioner cover and according to the spacer sleeve 6 of the selected respective numbers of thickness of thin-wall sleeve 3 successively, and be locked by nut 7, front and back thimble by lathe withstands on the centre bore 8 at last, adjust its concentricity, can process the cylindrical of thin-wall sleeve 3.
Adopt anchor clamps of the present utility model, can solve well the problem on deformation in thin-wall sleeve 3 processing, so that crudy is stable, have simple in structure, processing and the advantage such as easy to use, and the mandrel that need not prepare several sizes is for thin-wall sleeve 3 apolegamys; thin-wall sleeve 3 pack into smoothly and positioning accuracy higher, not only guarantee product quality but also can enhance productivity.
Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the utility model, and be not to be used as restriction of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
