Description

Technical Field

[0001] The invention relates to the field of tooling, in particular to universal tooling equipment for a switch cabinet chassis vehicle. Background Art

[0002] The switch cabinet chassis is an important component of the switch cabinet. After the punching holes on the switch cabinet chassis are formed at one time by a punch press and the switch cabinet chassis is bent by a bending machine, the folding edge joint area needs to be welded to achieve the purpose of firmness. Traditionally, different sizes of switch cabinet chassis require different tooling fixtures for tooling fixation, so that when the folding edge area is welded by a welding robot, the switch cabinet chassis is firmly clamped. However, this method of clamping switch cabinet chassis of different sizes with multiple tooling fixtures cannot be applied to the processing line for continuous processing, so that the welding processing of switch cabinet chassis of different sizes can only be performed manually, which greatly reduces the processing efficiency of the switch cabinet chassis and greatly increases the production cost of the switch cabinet chassis.
