Assembling and welding process method for stator machine seat

Abstract

The invention discloses an assembling and welding process method for a stator machine seat. The process method comprises the steps of preparing materials of semi-finished products according to the requirements of a drawing, horizontally putting the bottom of a frame plate on a platform, putting big bottom corners on two sides of the frame plate through supporting of a buttress, suspending five groups of pre-welded skeletons into the frame plate, adjusting the total length of a machine seat, the distance between every two adjacent groups and the concentricity, carrying out fixed overlap welding, assembling a joint hinge, an outer skin, a connecting plate and the big bottom corners; after fixed overlap welding is finished, welding and cleaning partial positions of the machine seat, welding bottom rib plates, outer skin and lower part side plates on a rolling tire, and then finishing the welding and cleaning of the residual positions; after the cleaning is finished, carrying out integralsandblasting on the machine seat, assembling and welding subsequent wire wrapping rods, and carrying out painting after welding lines and sizes are qualified. The assembling and welding process methodhas the advantages that the product quality is remarkably improved, the process method is reasonable and advanced, the actual operation is convenient, the manufacturing period is short, the cost is low, and the like.

Description

technical field [0001] The invention relates to an assembly and welding process method for a stator base of an air-cooled camera. Background technique [0002] The original manufacturing process of the stator frame of the condenser is to adopt the overall horizontal assembly. After the bottom frame plate is placed on the platform to adjust the root, the excitation end plate is placed on the bottom frame plate according to the drawing, and the verticality is adjusted to be fixed by lap welding. After determining the horizontal datum, assemble the clapboard ribs layer by layer from the excitation end, adjust the distance tolerance and concentricity of each layer of clapboards to fix them by lap welding, and then assemble the welded skin and exterior decorations after the skeleton is welded. However, after comprehensive analysis and discussion, it is considered that this scheme is not completely suitable for the assembly and welding work of this product. This method has many di...

Problems solved by technology

However, after comprehensive analysis and discussion, it is considered that this scheme is not completely suitable for the assembly and welding work of this product. This method has many difficulties and problems. The end plate and partition are assembled by crane, which takes up a lot of time for the crane and the site. Long; when assembling the ribs, a large number of temporary baffles are needed to assist in the positioning of the ribs, the process is cumbersome and difficult to operate, and the assembly accuracy of the ribs cannot be guaranteed; when assembling the end plate partitions of the machine base, each piece needs to be selected and adjusted. The center line, a total of 18 times, the cumulative assembly error is relatively large

All-position welding is required during skeleton welding, which is difficult to weld and has a long operating cycle; the machine base has a large amount of welding, and welding deformation has a great impact on the overall structural size, so the dimensional tolerance requirements cannot be guaranteed
