Description

Base device

Technical Field

The utility model relates to the technical field of production of constant-speed universal joints, in particular to a base device.

Background

CVJ is a constant velocity joint. It is a key component in the front wheel drive system of an automobile and is also used in four wheel drive or rear wheel drive systems. The CVJ can transmit the difference between the engine speed and the tire speed through the design of the universal joint without unnecessary vibration and fluctuation. The wheel hub comprises an inner sleeve, an outer sleeve, a ball, a universal joint cage and the like, wherein the inner sleeve is fixed on the wheel shaft, the outer sleeve is fixed on the wheel hub, the ball is connected with two sleeves, so that the two sleeves can rotate relatively, and the universal joint cage is fixed with the ball, so that the stability of the relative positions of the ball is ensured. CVJ is subjected to great loads and impacts during driving of the automobile, and thus needs to maintain good lubrication and sealing properties. The dust cover of CVJ finished product plays the foreign matter entering such as waterproof, sand prevention, and in order to guarantee the dust cover at present, gasket assembly position is accurate. The dust cover and the gasket are respectively pressed, and the production efficiency is lower.

Disclosure of Invention

The present utility model provides a base device, which solves the above-mentioned technical problems.

The scheme for solving the technical problems is as follows:

the utility model provides a base device, includes work piece, shield body, gasket body, bolt, spring, gasket base, equipment base and shield base, install the gasket base through spring elastic mounting in the equipment base, the top lid of equipment base is equipped with the shield base, the spacing gasket body of having placed in top of gasket base, the shield body of having placed at a spacing on the shield base, spacing grafting has the work piece in the equipment base, just the work piece runs through shield body and gasket body.

On the basis of the technical scheme, the utility model can be improved as follows.

Further, the equipment base and the dust cover base are fixed through bolt connection.

The beneficial effects of adopting the further scheme are as follows: the device base and the dust cover are convenient to be connected and fixed fast.

Further, the number of the springs is eight, and the springs are uniformly distributed between the gasket base and the equipment base.

The beneficial effects of adopting the further scheme are as follows: the workpiece is elastically supported by a spring.

The beneficial effects of the utility model are as follows: when the anti-dust gasket is used, the gasket body and the dust cover are sequentially placed in the gasket base and the dust cover base, then a workpiece is placed in the equipment base, then downward pressure is applied to the workpiece through the air cylinder or the hydraulic cylinder, so that the dust cover body is assembled in place, and then the gasket body is pushed in continuously under the reverse acting force of the spring until the dust cover body and the gasket body are completely assembled in place. And (5) assembling the dust cover body and the gasket body.

The foregoing description is only an overview of the present utility model, and is intended to provide a better understanding of the present utility model, as it is embodied in the following description, with reference to the preferred embodiments of the present utility model and the accompanying drawings.
