The thin-wall tubular workpiece clam tool has the beneficial effects that: the tool overcomes deformation caused by factors such as a relatively long cantilever, cutting vibration, unstable cutting and the like, and solves the problems such as lower processing precision, even unqualified processing and the like. A cam slide block mechanism is arranged, so that supporting parameters and workpiece clamping parameters in a clamping process and a processing process are strictly controlled, and therefore, in a turning process, the rigid support effect is sufficiently brought into play, and an effective method for solving the problems is provided for processing parts with similar structures.
Description
Technical field
The invention belongs to mechanical processing technique field, be specifically related to a kind of thin-walled tubular work piece holder frock.
Background technology
In field of machining, thin-walled tubular workpiece is one of difficult point of turnery processing, causes that because its wall is thin processing rigidity is poor and machining deformation very easily occurs, makes the Form and position error of part increase, and work pieces process quality not easily ensures.As shown in Figure 1, workpiece common in certain industry belongs to typical thin-wall pipe structure, workpiece draw ratio is more than 5:1, wall thickness is only 2mm, and workpiece material is 304 rustless steels, its impact flexibility and elongation percentage is higher, plasticity is higher, and workpiece rigidity and clamping rigidity are poor, therefore being susceptible to torsional deflection in Tutrning Process, cause bigger cylindricity and flatness error, machining accuracy is difficult to ensure that.
Summary of the invention
It is an object of the invention to overcome deficiency of the prior art, it is provided that a kind of thin-walled tubular work piece holder frock, this frock is effectively increased the clamping rigidity of thin-wall part, and machining accuracy is high and reproducible.
For solving prior art problem, the technical solution used in the present invention: a kind of thin-walled tubular work piece holder frock, including the ring flange having pedestal concurrently, coaxially it is fixed on ring flange, for fixing the sleeve of workpiece, coaxial rotation is arranged on the mandrel in sleeve, at least two groups are for the jacking mechanism of top tight workpiece, and drive the driving mechanism of jacking mechanism；Jacking mechanism can stretch thus the workpiece pre-tightening outside sleeve will be set in along sleeve diameter direction.
Preferably, cam and the slide block that jacking mechanism includes being arranged on mandrel is often organized；Skid is assemblied in the groove being radially opened on sleeve wall, and slides in groove under the effect of cam.
Preferably, the material of cam is Magnet, and the material of slide block is cast iron.
Preferably, cam has three along the equally distributed protruding circular arc of basic circle circular arc circumference, and corresponding slide block and the quantity of groove are also three and are uniformly distributed circumferentially.
Preferably, the quantity of jacking mechanism is four groups, and in adjacent two jacking mechanisms, the bossing of cam and groove are all crisscross arranged.
Preferably, the top end face of slide block is arc surface.
Preferably, driving mechanism includes end cap and worm-gears；End cap is assemblied in one end of sleeve by screw thread pair, it is possible to holds mandrel and stretches out the part outside sleeve；Worm gear in worm-gears is linked and packed in the end of mandrel by key, and worm screw is rotatably installed on end cap and engages with worm gear；One end of worm screw is stretched out outside end cap and offers interior hex slot at its end face.
The invention have the benefit that
1. this frock overcomes the deformation because the factors such as cantilever is longer, cutting vibration, cutting instability cause, the problems such as defective are even processed in machining accuracy reduction.
2. by arranging cam slide mechanism, make to be installed, the parameter that is installed of support in the course of processing and workpiece obtains strict control, making in turning process, give full play to the effect of rigid support, the processing for similar structures part provides the effective way solving problem.
3. realize slide block by worm-and-wheel gear to fit tightly with workpiece inner wall, and utilize latching characteristics to realize self-locking, be further ensured that the stability of the course of processing.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.Following example are only for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
If Fig. 2 is to shown in 5, a kind of thin-walled tubular work piece holder frock, including the ring flange 1 having pedestal concurrently, coaxially it is fixed on ring flange 1, for fixing the sleeve 2 of workpiece, coaxial rotation is arranged on the mandrel 3 in sleeve 2, four groups of jacking mechanisms for top tight workpiece, and drive the driving mechanism of jacking mechanism.
Often group jacking mechanism includes cam 5 and slide block 4, and cam 5 is arranged on mandrel 3, and sleeve 2 offers the groove radially arranged, and slide block 4 is slidedly assemblied in groove, and the top end face of slide block 4 is arc surface, and slide block 4 slides under the effect of cam 5 in groove；Cam 5 has three along the equally distributed protruding circular arc 10 of basic circle circular arc 11 circumference, and the slide block 4 of cam 5 correspondence is also three with the quantity of groove and is uniformly distributed circumferentially.The material of cam is Magnet, and the material of slide block is cast iron, consequently, it is possible to can be linked together by magnetic force between cam and slide block and avoid the occurrence of the situation that slide block skids off from groove and send.
In order to make pressure evenly act in workpiece inner wall, in two adjacent groups jacking mechanism, the bossing of cam 5 and groove are all crisscross arranged.
Driving mechanism includes end cap 6 and worm-gears, and the end of sleeve is a path section, and end cap is assembled in this path section by screw thread pair, it is possible to holding mandrel 3 and stretch out the part outside sleeve 2, the external diameter of end cap is not more than the external diameter of sleeve thus facilitating the installation of workpiece.Worm gear 7 in worm-gears is assemblied in the end of mandrel 3 by flat key 8, and worm screw 9 is rotatably installed on end cap 6 and engages with worm gear 7；One end of worm screw 9 is stretched out outside end cap 6 and offers interior hex slot at its end face.
The operation principle of the present invention and process
This frock is installed on lathe spindle, utilizes die nut to regulate worm screw 9 and make slide block 4 be in contraction state.Then workpiece shown in Fig. 1 is set in outside sleeve 2, after adjusting axial location, again regulates worm screw 9, make cam 5 rotate thus by outside for slide block 4 jack-up.Until the inwall of the fully extended top tight workpiece of slide block 4.Actual should in process, the external diameter of sleeve 2, arc top and the distance of cam 5 center of rotation of protruding circular arc 10, size that the height equidimension parameter of slide block 4 is both needed to according to workpiece are determined, therefore are not repeated.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvement and deformation, these improve and deformation also should be regarded as protection scope of the present invention.
