Description

Manipulator is snatched to thin wall pipe fitting Technical Field The utility model relates to a thin-wall pipe fitting grabbing manipulator. Background In the processing process of thin-wall pipe fittings, such as automobile wheel rims, the processing mode of some enterprises is to firstly roll round with plates, then weld joints, then spin out the cross-sectional shape of the wheel rims, finally stir friction welding with spokes to form the appearance of a final product, in order to improve the automation level, a manipulator is used for grabbing the wheel rims, but because the pipe wall is thinner, the pressure that can bear is limited, and because the pipe wall surface is an arc surface, the traditional mechanical gripper is not good to clamp, in order to stabilize the clamping, the clamping force needs to be increased, but too large clamping force can leave marks which are difficult to remove on the outer surface of the wheel rims, and the final quality of the wheel hubs is affected. Disclosure of utility model The utility model provides a thin-wall pipe fitting grabbing manipulator which is used for clamping a thin-wall pipe fitting, and the specific scheme is as follows: A thin-wall pipe grabbing manipulator comprises a supporting arm, wherein a connecting seat used for being connected with an execution end of a robot is arranged at the top of the supporting arm; The support arm comprises a top plate positioned at the top and 2 vertical plates extending downwards from the top plate, and a middle area is formed between the two vertical plates; A pair of cylinders with hinged bottoms are arranged in the middle area; the middle parts of the clamping arms which are symmetrically arranged at the center of the supporting arm are respectively connected to the supporting ends of the two sides below the vertical plate in a rotating way; the push rods of the pair of air cylinders are respectively and correspondingly connected to the top ends of the clamping arms; The lower ends of the clamping arms are respectively provided with a rubber chuck which is used for being attached to the peripheral surface of the thin-wall pipe fitting; The auxiliary supporting plate is connected to the outer vertical surface of the vertical plate far away from the center through connecting screws; the vertical plate comprises a first body, and a first avoidance area is arranged in the center of the lower end of the first body; The auxiliary support plate comprises a second body, and a second avoidance area is arranged in the center of the lower end of the second body. Further, the first body is further provided with a plurality of lightening holes which are arranged in a central symmetry mode. Further, the top of both sides of the second body is provided with a connecting plate body extending upwards respectively, and the connecting screw is arranged on the connecting plate body. Further, an adjusting long hole for convenient adjustment is formed in the connecting plate body, the adjusting long hole is vertically formed, and the connecting screw is arranged in the adjusting long hole. The utility model has the beneficial effects that: The thin-wall part clamping device has the advantages that the thin-wall part can be positioned and clamped without excessive clamping force, and the grabbing effect is greatly improved. The thin-wall pipe grabbing manipulator has the advantages of simple manufacture, convenient use, no scratch on the surface of a part, large diameter range of the adapting pipe, and the like.
