Description

Pump body automatic weld equipment Technical Field The invention belongs to the technical field of automatic welding equipment, and relates to pump body automatic welding equipment. Background In the field of pump body manufacturing, welding is an important process, and the welding quality directly influences the sealability, structural strength and service life of the pump body. Currently, pump body welding is generally performed by using welding equipment such as automatic or semi-automatic arc welding machines and plasma arc welding machines. When welding the pump body, it is often necessary to fix the pump body. The pump body is usually fixed by a simple three-jaw chuck or a special clamp from the outside. For the long pump body with larger length-diameter ratio, because the pump body is fixed at one end only, one end of the pump body far away from the clamp is easy to sag under the action of dead weight, so that the axis of the pump body is not parallel to the rotary workbench, and inclination is generated. The inclination makes the gap of the circumferential seam interface to be welded of the pump body uneven, and the welding quality is difficult to ensure. Conventional clamps lack good length adaptability. When pump bodies with different specifications are produced, the clamps are required to be replaced frequently or adjusted greatly, so that the production preparation time is prolonged, and the flexible production requirements of multiple varieties and small batches are not facilitated.
