Description

Swivel device based on integrated spot welding machine

Technical Field

The utility model relates to an integration spot welder equipment field especially relates to a change device based on integration spot welder.

Background

The integrated spot welding machine is widely applied to an automobile welding production line, is very important handheld spot welding equipment in the automobile welding production line, and comprises a rotating ring assembly, a resistance welding transformer, a cylinder, a suspender assembly, a front support part of a machine body, a welding arm, a handle, a matched water cooling system, a gas circuit system, an electric system and the like. The swivel assembly is an important basic component on the integrated spot welding machine, a transformer, a cylinder, a front support of a machine body, a hanging assembly, a handle and the like are connected to the swivel assembly, the whole integrated spot welding machine can rotate around the axis of the swivel assembly, and the existing integrated swivel assembly is not high in reliability, difficult to adjust and easy to deform after being stressed.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a change device based on integration spot welder that adjusts easily, the reliability is high and non-deformable.

The utility model adopts the technical scheme as follows:

the utility model provides a change device based on integration spot welder, includes change apron, outer change and adversion, and the adversion imbeds on the inner hole wall of outer change. The rotary ring cover plate is fixed on the end face of one side of the outer rotary ring, the rotary ring cover plate is annular, an annular sealing edge is machined on the inner hole wall of the rotary ring cover plate and used for sealing the inner rotary ring and preventing the inner rotary ring from being separated from the outer rotary ring, an inner ring pressing plate is fixed on the end face of the other side of the outer rotary ring, the outer diameter of the inner ring pressing plate is smaller than the inner hole diameter of the outer rotary ring, and the inner ring portion of the inner ring pressing plate is used for sealing the inner rotary ring and preventing the inner rotary ring from being separated from the other side of the outer rotary ring.

Preferably, a plurality of conical grooves are milled on the ring surface of the inner rotating ring, which is in contact with the annular sealing edge, and conical rolling needles are mounted in the conical grooves.

Preferably, a plurality of holes with opposite positions are formed in the rotating ring cover plate and the inner ring pressing plate along the circumference, and connecting pieces are installed in the holes.

Preferably, the holes in the rotating ring cover plate and the inner ring pressing plate are threaded holes.

The utility model has the advantages that:

(1) the last tapered slot of adversion ring and toper kingpin can bear radial and axial load to make the relative position of integration spot welder in the swivel and outer swivel can both easily be adjusted under level or vertical state, and the utility model discloses the reliability is high, non-deformable after the atress.

(2) The rotating ring cover plate is connected with the inner ring pressing plate together, and the inner rotating ring is limited from two directions, so that the inner rotating ring is not easy to separate.
