Abstract
The utility model provides an internal-support type mandrel combined clamp. The internal-support type mandrel combined clamp comprises a clamp body, a front press board, a mandrel and a rear press board. One end of the clamp body is clamped on a chuck of a lathe, and the other end of the clamp body sleeves a workpiece; the middle of the front press board is provided with a through hole which corresponds to the inner cavity of the workpiece in size, and the front press board sleeve the clamp body through the through hole; the mandrel comprises a large end and a small end, the large end is provided with threads, the radial dimension of the small end is not smaller than the diameter of the through hole, and the small end of the mandrel abuts against the through hole of the front press board; the middle of the rear press board is provided with a screwed hole, which corresponds to the inner cavity of the workpiece and the threads of the mandrel in size; the mandrel is threadedly connected with the rear press board; the rear press board abuts against the flanging inside the workpiece. By internally supporting the workpiece through the front press board and the rear press board, the internal-support type mandrel combined clamp solves the problem that workpieces in certain sizes cannot be directly fixed and machined through a mandrel, and has the advantages of being flexible in usage and saving the cost.
Description
Technical field
The utility model relates to a kind of fixture, specifically, has related to a kind of inner bearing type mandrel built-up jig of processing thin-walled shell workpiece.
Background technology
Parts of thin-wall casing easily by clamping deformation and processing poor rigidity, is the difficult problem in Vehicle Processing in Vehicle Processing always.At present, generally use for the clamping method of thin-wall case class part processing excircles and end face, mandrel or Small Taper mandrel support endoporus and chuck support endoporus can rise.Mandrel or the Small Taper mandrel support endoporus requirement inner bore of part that can rise has very high dimensional accuracy, and shape matching is simple, is preferably single hole, and if do not met and can not be suitable for, processing conditions is very restricted; Chuck support endoporus easily produces part deformation, affect the circularity of part outer and the flatness of end face, if part overhangs long, just must little cutting-in cut, so just cause working (machining) efficiency low, once and fly out at the excessive part that will cause of process cutting force, gently part, tool damage, heavy cause the generation of device damage, human casualty accident.
In order to solve the problem of above existence, people are seeking a kind of desirable technical solution always.
Summary of the invention
The utility model is to provide a kind of inner bearing type mandrel built-up jig, comprising:
Clamp body, its one end clamping, on lathe chuck, is arranged with workpiece on the other end;
Front pressuring plate, it is provided with through hole for centre position, and the corresponding described workpiece lumen body of its size arranges, and described front pressuring plate is arranged in workpiece lumen and by described through hole and is set on described clamp body;
Mandrel, it comprises large end and small end, and described large end is provided with screw thread, and described small end radial dimension is not less than described through-hole diameter, and described mandrel small end overhead is on described through hole;
Rear fender, it has the setting of the corresponding workpiece lumen body of screwed hole and size for centre position, the corresponding described mandrel thread of described screwed hole size, described mandrel is threaded with described rear fender, and described rear fender rests on the flange in workpiece.
Based on above-mentioned, described front pressuring plate is equilateral triangle.
Based on above-mentioned, described rear fender is equilateral triangle.
Base the above, the front end of described mandrel small end is sphere.
The utility model has adopted mandrel to fix forward and backward pressing plate, and by forward and backward pressing plate supporting workpiece inner surface, thereby make the utility model without endoporus clamping location, but clamping is on interior resonator end surface, has solved the processing problems of the workpiece that cannot locate with mandrel; Next on workpiece lumen step surface, has ensured the axiality of cylindrical and inner circle by forward and backward pressing plate inner support, and part outer and two end faces can process at one time, and cylindrical and end face can ensure very high positional precision; Add man-hour rigidity fine simultaneously, greatly improved working (machining) efficiency.

Detailed description of the invention
Below by detailed description of the invention, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure 1 and Figure 2,1, a kind of deicer for power transmission line, comprising: clamp body 1, its one end clamping, on lathe chuck, is arranged with workpiece 3 on the other end; Front pressuring plate 2, intermediate position is provided with through hole 7, the corresponding described workpiece setting of its size, described front pressuring plate 2 is arranged in workpiece 3 inner chambers and by described through hole 7 and is set on described clamp body 1; Mandrel 6, it comprises large end and small end, and described large end is provided with 5 screw threads, and described small end size is not less than described through hole 7 diameters, and described mandrel 6 small end overheads are on described through hole 7; Rear fender 4, it has screwed hole 8 for triangle and centre position, the corresponding described mandrel 6 screw thread settings of described screwed hole 8 sizes, described mandrel 6 is threaded with described rear fender 4, and described rear fender 4 rests on the flange in workpiece.
Further, described front pressuring plate 2 is triangle with described rear fender 4.
The benefit arranging is like this, front pressuring plate 2, holds out against by mandrel interior resonator end surface stretching with rear fender 4 simultaneously, makes on its inner chamber step surface that abuts against part, so just can clamped one time completes the processing of part outer and end face simultaneously.Described front pressuring plate 2, rear fender 4 are taken turns as triangle, in order to tilt pack workpiece 3 inner chambers into and can be pressed on interior resonator end surface, contact with apex with the locating surface of workpiece simultaneously, can effectively reduce due to the bad clamping deformation producing of positioning end facial plane degree.
Further, described front pressuring plate 2 is equilateral triangle, and the benefit arranging is like this that interior support force is evenly difficult for making workpiece 3 to be out of shape.
Further, described rear fender 4 is equilateral triangle, and the benefit arranging is like this that interior support force is more evenly difficult for making workpiece 3 to be out of shape.
Further, described front pressuring plate 2 is the triangle of end filing with rear fender 4, and the benefit of setting is like this, and filing wedge angle increases lifting surface area, and workpiece 3 is not yielding.
Further, the front end of mandrel small end is sphere, and the benefit arranging is like this that the front end of ball-type more easily compresses front pressuring plate than the front end of plane, plays fixing more firmly effect.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement detailed description of the invention of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
