Problems solved by technology

Due to the large number of blades and the heavy weight of the blades in this operation mode, the labor intensity of the operator is high; when welding, the ventilation effect inside the tank is poor, and more harmful gases and dust are likely to be generated during the welding process, and the working environment is harsh. The physical health of the operator is damaged, and other reasons have become the bottleneck restricting the improvement of the mixer truck production capacity

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.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an assembly welding tool for a tank body of a concrete mixer truck and a mixing blade and a welding process using the welding tool. Background technique [0002] The reason why the concrete mixer truck can mix and transport concrete and prevent concrete from solidification and segregation during transportation is that the spiral blade inside the core technology tank plays a vital role. The spiral blades are arranged inside the tank of the mixer truck in a special helical manner. In the previous production process, the workers placed the tank body of the mixer truck in sections in specific jigs, and then manually placed the tank inside the tank. After special stamping and forming, the stirring blades divided into small sections are lapped and welded inside the tank body step by step along the positions marked in advance on the inner surface of the tank in a certain order. Due to...
