Description

Axle housing positioning and clamping mechanism

Technical Field

The utility model relates to the field of instruments for producing automobile parts, in particular to an axle housing positioning and clamping mechanism.

Background

The axle housing is an important part of the driving axle assembly of the commercial vehicle, and the machining precision of the axle housing directly influences the running stability of the vehicle; in the production and processing process of the axle housing, the axle housing is usually required to be clamped and fixed so as to be convenient for carrying out working procedures such as machining, welding and the like. After the axle housing is leveled, the two sides of the axle housing are required to be clamped and fixed, however, the existing factory adopts a single-hinge supporting and pressing block, and the single-hinge supporting and pressing block has the problems that the opening angle is smaller, the single-hinge supporting and pressing block cannot be completely opened, the axle housing has larger weight, is generally placed in a hoisting mode, cannot be directly placed from top to bottom, and needs a certain inclined angle to be relatively and transversely placed and opened for issuing the supporting and pressing block, so that the axle housing is relatively inconvenient to use.

In order to solve the problems, the proposal is generated.

Detailed Description

The utility model is further illustrated by the figures and examples.

As shown in fig. 1-4: the utility model provides a axle housing positioning and clamping mechanism, locate on base 14, be equipped with leveling mechanism 1 on the base 14, location hold-down mechanism 2 locates leveling mechanism 1 axial both sides respectively, and leveling mechanism 1 is used for axle housing 13 to level (leveling rotary mechanism pushes down, and the leveling decline mechanism drives whole mechanism and descends, until axle housing 13 lute face and leveling rotary mechanism briquetting parallel and level down, that is axle housing 13 leveling is accomplished), presss from both sides tightly through location hold-down mechanism 2 to axle housing 13 both sides during the use.

It should be noted that, the inventor of the design of the leveling mechanism 1 has issued a patent and disclosed the foregoing, and the present embodiment is not explained in detail.

The positioning and compacting mechanism 2 comprises a base 4, a shield 12 is arranged on one side of the base 4, an air cylinder 6 is connected to the bottom of the shield 12, a pressure supporting block 8 is hinged to the output end of the air cylinder 6, a hinge block 7 is hinged to the output end, close to the air cylinder 6, of the pressure supporting block 8, the other end of the hinge block 7 is hinged to one side of the base 4, and the hinge block 7 is in a vertical state in a normal state.
