Description

Technical Field

[0001] The utility model belongs to the technical field of pusher manufacturing, and particularly relates to an electric welding tooling for a pusher. Background Technique

[0002] A pusher, as Figure 5 described, is an existing pusher. It includes a main push rod 1', a first branch push rod 2' and a second branch push rod 3'. The rear side of the upper end surface of the first branch push rod 2' is welded to the front side of the lower end surface of the main push rod 1'. A convex block 4' is provided at the front end of the second branch push rod 3' and the convex block 4' is located on the lower end surface of the second branch push rod 3'. A welding convex block 5' is provided on one side of the rear end of the second branch push rod 3'. The outer side surface of the welding convex block 5' is welded to the side surface of the main push rod 1'. A gap 6' is left between the first branch push rod 2' and the second branch push rod 3'. At present, when manufacturing a pusher, the welder uses a cushion block to fit the main push rod 1' and the first branch push rod 2' before welding, that is, the parts to be welded on the rear side of the upper end surface of the first branch push rod 2' and the front side of the lower end surface of the main push rod 1' are brought together before welding. Then the welder manually welds the main push rod 1' and the first branch push rod 2'. After that, the welder uses a cushion block to fit the second branch push rod 3' and the main push rod 1' (the main push rod 1' where the first branch push rod 2' is welded) before welding, that is, the outer side surface of the welding convex block 5' in the second branch push rod 3' and the part to be welded on the side surface of the main push rod 1' are brought together before welding. Then the welder manually welds the main push rod 1' and the second branch push rod 3'. However, using a cushion block to fit a pusher before welding not only has low welding efficiency but also unstable welding quality. Content of the Utility Model
