Abstract
The utility model discloses a kind of semiaxis fixture, comprise lathe, described lathe is fixed with chuck, described chuck is provided with three claws, described claw is provided with alignment pin, and three of three described alignment pins away from the other end end face being fixed on claw at grade; Lathe is provided with fixed cover away from chuck one side, and described fixed cover is provided with screwed hole, and hold-down nut is fixed through screwed hole and fixed cover; The axle portion of semiaxis penetrates in lathe, until its deep bid contacts with alignment pin, in the blind hole that described axle portion afterbody cover has metancenter to overlap, hold-down nut screws in and holds out against fixing by metancenter cover in fixed cover.The utility model structure is simple, and gripping is convenient, and product percent of pass is higher, and effectively prevents due to the vibrations of axle portion and make semiaxis depart from original benchmark, can reduce production cost widely.
Description
Technical field
The utility model relates to the auxiliary clamp that a kind of automobile axle shaft adds man-hour.
Background technology
To (need ensure the axiality of deep bid and shallow bid) when the deep bid in automobile axle shaft processing dish portion and shallow bid, general way is first inserted in lathe in the axle portion of semiaxis, then uses scroll chuck clamp shaft portion, finally process deep bid and shallow bid.There is following defect in this mode:
1, lack positioning datum, general workman is position by experience when operating, therefore product quality is very unstable;
Even if 2 accurate positionings, but the structure not having again fixed axis portion because axle portion is long, therefore can shake adding axle in man-hour portion, make semiaxis depart from original machining benchmark, cause higher percent defective.
3, gripping is inconvenient, affects operating efficiency.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of being applied on lathe and makes the fixture that automobile axle shaft percent defective is low, location is convenient, production efficiency is high.
For achieving the above object, the utility model provides a kind of semiaxis fixture, comprise lathe, described lathe is fixed with chuck, described chuck is provided with three claws, described claw is provided with alignment pin, and three of three described alignment pins away from the other end end face being fixed on claw at grade; Lathe is provided with fixed cover away from chuck one side, and described fixed cover is provided with screwed hole, and hold-down nut is fixed through screwed hole and fixed cover; The axle portion of semiaxis penetrates in lathe, until its deep bid contacts with alignment pin, in the blind hole that described axle portion afterbody cover has metancenter to overlap, hold-down nut screws in and holds out against fixing by metancenter cover in fixed cover.
The beneficial effects of the utility model are: the utility model structure is simple, and gripping is convenient, and product percent of pass is higher, and effectively prevent due to the vibrations of axle portion and make semiaxis depart from original benchmark, can reduce production cost widely.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of semiaxis fixture of the utility model detailed description of the invention.
Fig. 2 is the structural representation of a kind of semiaxis fixture of the utility model detailed description of the invention.
Fig. 3 is the sectional view of a kind of semiaxis fixture of the utility model detailed description of the invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
See Fig. 1 to Fig. 3, a kind of semiaxis fixture, comprises lathe 1, described lathe 1 is fixed with chuck 2, described chuck 2 is provided with three claws 3, and described claw 3 is provided with alignment pin 4, and three of three described alignment pins 4 away from the other end end face being fixed on claw 3 at grade;
Lathe 1 is provided with fixed cover 7 away from chuck 2 one side, and described fixed cover 7 is provided with screwed hole, and hold-down nut 6 is fixed through screwed hole and fixed cover 7;
The axle portion 83 of semiaxis 8 penetrates in lathe 1, until its deep bid 82 contacts with alignment pin 4, described axle portion 83 afterbody cover has metancenter to overlap in the blind hole of 5, and described metancenter cover 5 is mainly used in preventing axle portion 83 from shaking, and metancenter cover 5 holds out against fixing by screwing in fixed cover 7 by hold-down nut 6.
During use, due to the positioning datum be made up of alignment pin 4, therefore directly axle portion 83 is inserted in lathe 1, until deep bid touches alignment pin 4, and axle portion 83 afterbody loads in metancenter cover 5, and metancenter cover 5 is fixed by hold-down nut 6 again, so indirect secures axle portion 83 afterbody, and due to its afterbody fixing dead, therefore also leave certain damping space, the afterbody in axle portion 83 can be made to reach the effect of nature damping and don't affect initial positioning datum.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technical staff in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
