Abstract
A kind of thin-wall sleeve processing clamp, comprises chuck (1); At least two claws (2) removably connected with described chuck (1); The soft pawl (3) removably connected with described claw (2); The nearly thin-wall sleeve side of described soft pawl (3) is circular arc, and the end face clamping part area of described soft pawl (3) is greater than the end face clamping part area of claw (2).
Description
Technical field
The utility model relates to a kind of clamping tool for machine work, especially relates to a kind of clamp for machining of processing thin-walled cover.
Background technology
When thin-wall sleeve carries out fine finishining, easily deform, thus affect its precision.In order to address this problem, be developed the fixture of various structure, as a kind of end face compressing fixture be widely used, it is primarily of setting element (as mandrel, spacer shell etc.) pressure ring and nut composition, rely on the axial force of nut to make workpiece to be machined be fixed between pressure ring and setting element, then process.But, such fixture also exists two deficiencies: first, owing to there is gap between setting element and workpiece to be machined, adding man-hour, owing to being subject to the impact of cutting force, workpiece will deform, and, the closer to workpiece centre (axis), be out of shape more serious, thus, have impact on the machining accuracy of workpiece; The second, because workpiece to be machined wall is thinner, when clamping pressure is larger, workpiece is also easily out of shape, and meanwhile, also workpiece both ends may be extruded impression, if pressure is less, then processing work easily loosens.
And the thin-wall sleeve processing clamp of routine is scroll chuck, tripartite exerts a force clamping, and be difficult to the form tolerance requirement ensureing workpiece, the uniformity of work pieces process is poor.Repeatedly need reverse end for end clamping workpiece and process, waste time and energy.Because workpiece is thinner, when the tight power of angle is larger, outer surface is irregular status, affects machining accuracy, under the effect of insufficient clamping force, workpiece displacement can be made or depart from clamped condition, and because of the unexpected increase of impulsive force, and the rigidity of workpiece is not enough, vibrates, as self-excited vibration, there is extreme influence to machining.
Existing processing mode major defect is as follows:
1., because this product outer wall is thinner, be therefore out of shape comparatively large after Product processing, product processing quality is difficult to ensure;
2. the bad control of the size of clamping chuck to clamping force, can make workpiece displacement or depart from clamped condition, and because of the unexpected increase of impulsive force, and the rigidity of workpiece is not enough, vibrate (self-excited vibration), has extreme influence to machining.
3. the product percent defective after processing is high, and production efficiency is low, and the most of the time is wasted in chuck and repeatedly reverses end for end on clamping workpiece.
Utility model content
In order to overcome the defect of prior art, the technical problem that the utility model solves is: provide a kind of clamping firm, the on-deformable thin-wall sleeve processing clamp of workpiece in clamping process.
In order to solve the problems of the technologies described above, the thin-wall sleeve processing clamp that the utility model provides, it comprises chuck; At least two claws removably connected with described chuck; The soft pawl removably connected with described claw; The nearly thin-wall sleeve side of described soft pawl is circular arc, and the end face clamping part area of described soft pawl is greater than the end face clamping part area of claw.
As optimal technical scheme, the thin-wall sleeve processing clamp that the utility model provides, described chuck is scroll chuck.
As further improvement opportunity scheme, the thin-wall sleeve processing clamp that the utility model provides, the nearly thin-wall sleeve end of described soft pawl is also connected with elastic jacket.
On the basis of above-mentioned improvement project, as further improvement opportunity scheme, the thin-wall sleeve processing clamp that the utility model provides, described elastic jacket is circular arc, and each elastic jacket surrounds the annular sleeve that has gap jointly.
As further improvement opportunity scheme, the thin-wall sleeve processing clamp that the utility model provides, the nearly chuck-end of described claw is provided with the locating slot that cross section is rectangle, described chuck is provided with the positioning boss that cross section is rectangle, described locating slot matches with described positioning boss, after the locating slot of described claw coordinates with positioning boss, claw is bolted on chuck again.
When not conflicting, above-mentioned improvement or preferred version can be implemented alone or in combination.
The technical scheme advantage that the utility model provides is as follows: add holding area because claw is connected with soft pawl, soft pawl itself is yielding compared with workpiece, make workpiece in clamping process not yielding and clamp firm.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Thin-wall sleeve processing clamp as depicted in figs. 1 and 2, comprise scroll chuck 1, nearly chuck 1 end of claw 2 is provided with the locating slot that cross section is rectangle, described chuck 1 is provided with the positioning boss that cross section is rectangle, described locating slot matches with described positioning boss, after the locating slot of described claw 2 coordinates with positioning boss, claw 2 is bolted on chuck again, three soft pawls 3 are removably connected with three claws 2 respectively by bolt, nearly thin-wall sleeve 5 side of soft pawl 3 is circular arc, nearly thin-wall sleeve 5 end of soft pawl 3 is also connected with elastic jacket 4, the end face clamping part area of soft pawl 3 and elastic jacket 4 is all greater than the end face clamping part area of claw 2.Elastic jacket 4 is circular arc, and each elastic jacket 4 surrounds the annular sleeve that has gap jointly.
Obviously, the utility model is not limited to above preferred embodiment, in the spirit that also can limit in the utility model claim and description, carry out conversion and the improvement of various ways, can same technical problem be solved, and obtain the technique effect of expection, therefore not repeat.Those of ordinary skill in the art can from content disclosed in the utility model directly or all schemes associated, as long as within the spirit limited in claim, also belong to protection domain of the present utility model.
