Abstract
The invention relates to an assembly welding fixture for a tank body and stirring blades of a concrete mixer and a process for welding by utilizing the welding fixture. According to the welding process, the moulded large partitioned stirring blades are attached to a blade parent plate on an inner cone male die correspondingly one by one and are subjected to butt welding to form an integral spiral blade in the partitioned tank body; the inner cone male die is pushed into the partitioned tank body by a lifting device, so that the spiral blade is in bonded with the tank body to weld quickly and fill gaps, and after bonding, the bonding part of the spiral blade and the partitioned tank body is subjected to spot welding; and a tank body rotating substrate which is put into the partitioned tank body is rotated and contracted by matching with the lifting device, so that the blade parent plate on the inner cone male die is separated from the large partitioned spiral blades, and the inner cone male die withdraws from the partitioned tank body. By the welding fixture and the welding process, the influence of harmful gas and dust on the health condition of operators due to small operation space during the welding in the tank body is avoided.
