Technical field
The utility model relates to clamping tool for machine work, particularly a kind of excircle of barrel-shaped parts Special Fixture for Machining.
Background technology
Tube kind part, the rough turning processing of the cylinder jacket part particularly produced in enormous quantities is all use as fixture with scroll chuck.Due to the design feature of the part of sleeve type itself, namely the diameter of axle is than very large, and when three-jaw clamping, clamping force is comparatively large, and simultaneously because the parts such as cylinder sleeve are longer, when processing, cutting force is large, and clamping force can not meet the demands, and all needs the afterbody in addition supplemental support at part.
Utility model CN 202824716 U discloses a kind of sleeve part rough turning clamp for machining, this fixture comprises taper mandrel, pull bar, taper ringfeder, spring and nut, the cylindrical of taper ringfeder circumferentially evenly axially opens shrinkage joint, taper ringfeder is contained on the outer wall of taper mandrel along axis direction through spring housing, pull bar is through taper mandrel, the centre bore of spring and taper ringfeder, one end hold-down nut of pull bar, taper ringfeder does radial harmomegathus under the effect of the conical surface cooperatively interacted, when taper ringfeder coordinates the conical surface to be moved to the left along the axis direction of taper mandrel, taper ringfeder radial direction is opened, the taper ringfeder radial contraction when taper ringfeder coordinates the conical surface to move right along the axis direction of taper mandrel, prior art alleviates the labour intensity of employee, ensure converted products quality, enhance productivity.But, in prior art, need taper mandrel and taper ringfeder first to coordinate, again by the mating reaction of pull bar, hold-down nut and spring, make taper ringfeder under the effect of the conical surface that cooperatively interacts, do radial harmomegathus, structure is simplified not, operates and has certain trouble.
Summary of the invention
The utility model technical issues that need to address are to provide a kind of excircle of barrel-shaped parts Special Fixture for Machining, this fixture in guarantee converted products quality, enhance productivity effect when, structure is simple, easy to operate, suitablely widelys popularize.
For solving above-mentioned technical problem, a kind of excircle of barrel-shaped parts Special Fixture for Machining of the present utility model, comprises mandrel and ringfeder; Described ringfeder is provided with central through hole, and mandrel and ringfeder are coordinated by central through hole to be installed; Described ringfeder is provided with relative cell body, and one end of described cell body is opening, and the other end of cell body is cecum; Described central through hole is tightening hole, described mandrel is processed with fastening block and described tightening hole matches; The two ends of described mandrel are provided with screw thread, described screw thread coordinates and is provided with adjusting nut.
Further, described tightening hole is taper hole, and described fastening block is cone, and described taper hole and described cone match.
Further, the tapering of described taper hole is 10-30 °.
Further, packing ring is provided with between described adjusting nut and ringfeder.
Further, the material of described ringfeder is aluminium alloy.
After adopting said structure, by the mating reaction of adjusting nut and mandrel, utilize the mating reaction in tightening hole in fastening block and ringfeder on mandrel, ringfeder is made to do radial harmomegathus, effectively prevent the cylindrical of thin-wall sleeve tube kind part problem of clamping, machining deformation during fine finishining on lathe and grinding machine, simplify part of the prior art simultaneously, while providing cost savings, also facilitate operation.

Detailed description of the invention
As shown in Figures 1 and 2, a kind of excircle of barrel-shaped parts Special Fixture for Machining of the present utility model, comprises mandrel 1 and ringfeder 4; Described ringfeder 4 is provided with central through hole 5, and mandrel 1 and ringfeder 4 are coordinated by central through hole 5 to be installed; Described ringfeder 4 is provided with relative cell body 6, and one end of described cell body 6 is opening, and the other end of cell body 6 is cecum; Described central through hole 5 is tightening hole, and described mandrel 1 is provided with fastening block 7 and matches with described tightening hole, and namely tightening hole and fastening block 7 can carry out relative motion under the effect of external force, make the ringfeder 4 having cell body 6 can do radial harmomegathus; The two ends of described mandrel 1 are provided with screw thread, described screw thread coordinates and is provided with adjusting nut 2.The quantity of adjusting nut 2 is two, and an adjusting nut uses in clamping process, is with moving mandrel 1 to move, facilitates easy to operate by adjusting nut 2; Another adjusting nut clamping later stage is used for the last position of fixed central spindle 1, and ensure that in process, mandrel 1 can not offset.
And the material of ringfeder 4 is aluminium alloy, the light weight of aluminium alloy, and plasticity is good, by force restorative for after radial harmomegathus, extends service life.
Be provided with packing ring 3 between described adjusting nut 2 and ringfeder 4, packing ring 3 ensure that the fastness of clamping between adjusting nut 2 and ringfeder 4.
During use, thin-wall sleeve tube kind part that will be processed is sleeved on ringfeder 4, is now the relative cooperation loosened between workpiece with ringfeder 4, then mandrel 1 is sleeved on ringfeder 4, then fastening block 7 coordinates with tightening hole, adjusting nut 2 by thread set in mandrel one end, then the power that mandrel 1 one is outside is given, fastening block 7 can be axially moved along the axis in tightening hole, because ringfeder 4 is provided with relative cell body 6, when fastening block 7 axially moves along the axis in tightening hole, ringfeder 4 is in by the state of spreading, then make it and the coordinating to become and closely cooperate of workpiece inner wall, effectively prevent the cylindrical of workpiece clamping during fine finishining on lathe and grinding machine, machining deformation, ensure and improve crudy, thus improve production efficiency, cut down finished cost.
As shown in Figure 3, further, described tightening hole is taper hole, described fastening block 7 is cone, described taper hole and described cone match, namely the inner conical surface of ringfeder 4 and the male cone (strobilus masculinus) of mandrel 1 upper cone coordinate, mandrel 1 is when the effect of external force makes it and ringfeder 4 makes move toward one another, then reach the object that ringfeder 4 makes radial harmomegathus, make it and the coordinating to become and closely cooperate of workpiece inner wall, effectively prevent the cylindrical of workpiece clamping, machining deformation during fine finishining on lathe and grinding machine, ensure and improve crudy, thus improve production efficiency, cut down finished cost.
Further, the tapering of described taper hole is 10-30 °, and such tapering is arranged, and both ensure that the normal use of instrument, and has reduced the wearing and tearing in the process of taper hole and cone relative motion simultaneously, and extended its service life.
The above; be only detailed description of the invention of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should define with claim is as the criterion.
