Description
Technical field
The utility model relates to a kind of bearing machining fixture, especially relates to a kind of thin-wall bearing ferrule endoporus turning clamp.
Background technology
Lasso is the vitals of bearing, in the endoporus of thin-wall bearing ferrule or the Tutrning Process of cylindrical, there is the problem of positioning and clamping difficulty, thus affects turnery processing efficiency and the crudy of thin-wall bearing ferrule.
The installation way of existing thin-wall bearing ferrule endoporus turning clamp is: with the cast iron tire slightly larger than processed lasso size, mold leaves a groove, for the distortion after mold clamping, when on clamping to lathe, the distortion of mold is utilized to reach the object of clamping thin-wall bearing ferrule.Because the wall of bearing ring is thin, clamping force is slightly large, and the easy stress deformation of bearing ring, cause clamping point not overlap with the anchor point of lasso, and the size of clamping force is difficult to effective control.After turnery processing completes, under clamping state, measure the size qualification of endoporus, after clamping force is removed, make lasso produce elastic deformation due to the internal stress effect produced the clamping force of lasso in process, cause thin-walled lasso to remove the inconsistent of anteroposterior dimension in clamping force, processing dimension error is comparatively large, thus produces more substandard products, even waste product, qualification rate is lower, causes production cost to rise, and production efficiency reduces.
Utility model content
The applicant is for above-mentioned problem, be studied improvement, there is provided a kind of thin-wall bearing ferrule endoporus turning clamp, structure is simple, and convenient mounting and clamping is quick, accurate positioning, clamping force is stablized, and reduces processing dimension error, improves the turning qualification rate of thin-wall bearing ferrule, improve working (machining) efficiency, reduce production cost.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of thin-wall bearing ferrule endoporus turning clamp, comprise the clamp body of tubular, bottom in described clamp body is provided with the locating hole seat for locating thin-wall bearing ferrule one end cylindrical, hold-down ring slip cap is contained in described clamp body, described hold-down ring is provided with internal taper hole, tension ring is arranged in described hold-down ring, and described tension ring is provided with the male cone (strobilus masculinus) matched with the internal taper hole of described hold-down ring; At least two stop screws connect described clamp body through the hole on described hold-down ring, and described clamp body and described hold-down ring are evenly provided with several bolts hole connecting lathe spindle; Be provided with between bottom surface in the inner face of described hold-down ring and described clamp body and compress gap.
Further:
The outer end of described hold-down ring is provided with rib.
Technique effect of the present utility model is:
A kind of thin-wall bearing ferrule endoporus turning clamp disclosed in the utility model, structure is simple, convenient mounting and clamping is quick, clamping force direction overlaps with ferrule orientation point, accurate positioning, and clamping force is stablized, reduce processing dimension error, improve the turning qualification rate of thin-wall bearing ferrule, improve working (machining) efficiency, reduce production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
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.
As shown in Figure 1, the utility model comprises clamp body 1, clamp body 1 is in shallow tubular, bottom in clamp body 1 is provided with the locating hole seat 101 for locating thin-wall bearing ferrule one end cylindrical, and hold-down ring 3 slip cap is contained in clamp body 1, and hold-down ring 3 is provided with internal taper hole, tension ring 4 is arranged in the internal taper hole of hold-down ring 3, tension ring 4 is provided with the male cone (strobilus masculinus) matched with the internal taper hole of hold-down ring 3, and tension ring 4 is made up of vulcanie, and clamp body 1, hold-down ring 3 are processed by steel.At least two stop screws 2 are through the hole jockey body 1 on hold-down ring 3, tension ring 4 and hold-down ring 3 can only move axially in the scope of stop screw 2, stop screw 2 is for limiting the position of hold-down ring 3, tension ring 4, avoid hold-down ring 3, tension ring 4 deviates from clamp body 1, operation easy to setup.Clamp body 1 and hold-down ring 3 are evenly provided with respectively several bolts hole 5 for connecting lathe spindle, the quantity of bolt hole 5 is identical with the connecting bolt quantity on lathe spindle.Be provided with between bottom surface in the inner face of hold-down ring 3 and clamp body 1 and compress gap A, the size compressing gap A matches with the conical surface between tension ring 4, hold-down ring 3, determines the clamping force to processed thin-wall bearing ferrule.The outer end of hold-down ring 3 is also provided with rib 301, prevents tension ring 4 from outwards skidding off.
During clamping operation; thin-wall bearing ferrule 7 is through the endoporus of tension ring 4 and the locating hole seat 101 pushed bottom clamp body 1; make coarse positioning by one end of locating hole seat 101 pairs of thin-wall bearing ferrules 7, have larger gap between the cylindrical of locating hole seat 101 and thin-wall bearing ferrule 7, easy to setup; Turning clamp loads onto lathe spindle together with thin-wall bearing ferrule 7, bolt 6 on lathe spindle is through the bolt hole 5 on clamp body 1 and hold-down ring 3, with nut, hold-down ring 3 is tightened to clamp body 1 direction, due to the effect of the conical surface between hold-down ring 3 and tension ring 4, tension ring 4 inwardly shrinks the cylindrical of clamping thin-wall bearing ferrule 7.According to actual needs, appropriate design compresses size and the frustoconical bevel angle between tension ring 4 and hold-down ring 3 of gap A, obtains rational clamping force.
