Abstract

The utility model relates to a thin wall ring gear class part gear shaping anchor clamps, including T shape bolt, packing ring, nut, gland, positioning disk, hexagonal nut, plain washer, stud, parallels, interior hexagonal socket cap bolt, clamp plate, the positioning disk passes through T shape bolt, plain washer, hexagonal nut and gear shaping machine tool table rigid coupling, the little clearance fit of tang location in work piece excircle and the positioning disk. The step is pressed at the work piece up end in the gland, gland hole and work piece excircle clearance fit, and gland lower extreme edge compresses tightly on the positioning disk through hexagonal nut, plain washer, stud, parallels, clamp plate. The utility model discloses simple structure, convenient reliable, low cost had both compressed tightly the work piece, had reduced the work piece again and had warp and influence the machining precision, therefore had fine application prospect at quick -witted processing enterprises.

Description

Thin-wall annular gear class part gear-shaping clamp
Technical field
The utility model relates to Gear Shaping clamp art, particularly relates to a kind of thin-wall annular gear class part gear-shaping clamp.
Background technology
In the drive axle of many heavy trucks and engineering truck, have wheel hem retarding mechanism, and ring gear class part is requisite in wheel hem retarding mechanism.The tooth blank structure of this part is circular thin-wall, and in Gear Shaping process, workpiece produces moderate finite deformation under the clamping power effect of conventional clamp, and after causing processing, ring gear precision is difficult to ensure, cannot reach product quality requirement.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect, provides a kind of structure simple, convenient thin-wall annular gear class part gear-shaping clamp reliable, with low cost.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of thin-wall annular gear class part gear-shaping clamp, comprise tommyhead bolt 1, packing ring 2, nut 3, gland 4, positioning disk 5, six square nut 6, plain washer 7, stud 8, parallels 9, interior hexagonal cylindrical hook bolt 10, pressing plate 11, positioning disk 5 is affixed with shaping machine workbench by tommyhead bolt 1, plain washer 2, six square nut 3, and workpiece 12 cylindrical coordinates with positioning disk 5 inner stopper small―gap suture locates.In gland 4, step is pressed in workpiece 12 upper surface, gland 4 endoporus and workpiece 12 cylindrical matched in clearance.Gland 4 lower edge is pressed on positioning disk 5 by six square nuts 6, plain washer 7, stud 8, parallels 9, pressing plate 11.
Preferably, the fit clearance of gland 4 endoporus and workpiece 12 cylindrical is 1mm.
Preferably, the periphery of gland 4 evenly offers kidney slot 13.
Preferably, the quantity of pressing plate 11 is 3 pieces.
The utility model gland adopts the structure that upper thicker, the middle wall thickness of lower wall thickness is thinner, and circumferentially evenly offering kidney slot, ensure that in gland, step is evenly pressed in the upper surface of ring gear, ring gear upper end is made evenly to bear thrust, both compressed workpiece, and additionally reduced workpiece deformation and affect machining accuracy.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further.
As shown in Fig. 1 ~ 2; thin-wall annular gear class part gear-shaping clamp comprises tommyhead bolt 1, packing ring 2, nut 3, gland 4, positioning disk 5, six square nut 6, plain washer 7, stud 8, parallels 9, interior hexagonal cylindrical hook bolt 10, pressing plate 11; positioning disk 5 is affixed by tommyhead bolt 1, packing ring 2, nut 3 and shaping machine workbench, and workpiece 12 cylindrical coordinates with positioning disk 5 inner stopper small―gap suture locates.The quantity of pressing plate 11 is 3 pieces.
In gland 4, step is pressed in workpiece 12 upper surface, gland 4 endoporus and workpiece 12 cylindrical matched in clearance, avoids the accurate location of interfering workpiece, the preferred 1mm of its fit clearance.The periphery of gland 4 evenly offers kidney slot 13.Gland 4 lower edge is pressed on positioning disk 5 by six square nuts 6, plain washer 7, stud 8, parallels 9, pressing plate 11, makes ring gear upper end evenly bear thrust, has both compressed workpiece, turn avoid the impact of workpiece deformation on machining accuracy.
The use step of the utility model fixture is as follows: be 1. arranged on shaping machine workbench by fixture, correct positioning disk with dial gauge, and inner stopper run-out error is in 0.01mm, and inner stopper end face run-out error, in 0.01mm, tightens six square nuts; 2. the workpiece tooth base after finish turning is put into the inner stopper of fixture positioning disk; 3. gland is covered on the ring gear of workpiece; 4. three pressing plates are pressed in the lower edge of gland; 5. three six square nuts are evenly tightened at diagonal angle; 6. after workpiece ring gear gear shaping completes, unclamp three six square nuts, three pressing plates are moved backward, takes off gland, then take out the workpiece after gear shaping, complete the working cycles of a Gear Shaping.
The utility model is not limited to above-mentioned embodiment, in the ken that art those of ordinary skill possesses, can also make various change under the prerequisite not departing from the utility model aim.
