In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of device that is used to weld valve, comprise swivel joint, the outer surface of described swivel joint is provided with the drive unit that makes swivel joint generation rotation, one end of swivel joint is arranged with the left body of valve to be welded, the right body of valve to be welded is fitted on the left body, the boundary of the left and right body of described valve to be welded is provided with welding gun, is equipped with second joint in the described right body, and the second joint end is provided with second support.
In the technique scheme, described swivel joint has intake tunnel, and second joint has exhalant canal.
In the technique scheme, also comprise slide rail, be equipped with first slide block on the described slide rail, the top of described first slide block is provided with first support, first support upper end is connected with the support of bearing, and the side of described first support also is provided with first cylinder, and the cylinder rod of first cylinder is fixed on first support, the inner surface of the described support of bearing is provided with bearing, and bearing holder (housing, cover) is located on the swivel joint.
In the technique scheme, also be equipped with second slide block on the described slide rail, described second support is fixed on second slide block, and the side of described second support is provided with second cylinder, and the cylinder rod of second cylinder is fixed on second support.
In the technique scheme, the described drive unit that makes swivel joint generation rotation comprises passive and synchronous belt wheel, motor, and the output shaft of described motor and passive and synchronous belt wheel pass through belt transmission.
Beneficial effect: the utility model compared with prior art has following beneficial effect:
1) adopting the utility model to drive valve to be welded by swivel joint rotates, welding gun rotates a circle with respect to valve to be welded like this, and rotating speed of motor is highly stable, and therefore valve one all weld seams to be welded are all very even, improved production efficiency greatly, and the weld seam uniformity is better;
2) the utility model the time can feed cooling fluid in welding valve internal is cooled off, thereby prevents that sealing ring distortion and pad, spring etc. from becoming slack, thereby guarantees that valve seal is reliable;
3) the utility model can move the position of valve to be welded easily, and be located near the welding gun when changing valve to be welded, and operation is very easy.
