Rectangular pipe edger for bus skeleton welding

Abstract

The invention discloses a rectangular pipe edge wrenching device for welding of a passenger car framework. The rectangular pipe edge wrenching device comprises a clamping block and a clamping handle. The clamping block is a round block. A first notch and a second notch are formed in the round block. Slots are formed in the opposite inner side faces of the second notch. The clamping handle is a bar-shaped rod. One end of the bar-shaped rod is fixedly provided with a protruding block matched with the second notch. Protruding bars matched with the slots are fixed to the two side faces of the protruding block. The tool is designed for bending of a plate of a car body fixing frame on a passenger car and is made of metal materials, the structure is light, manufacturing is easy, and operation is convenient; and the problem that edge wrenching needs to be conducted before welding of a rectangular pipe in the passenger car manufacturing industry is solved, in addition, the product quality is improved after the tool is used, the labor time is shortened, convenience is brought to welding of the framework, the rework rate is reduced, and the human resource cost is saved.

Description

technical field [0001] The invention belongs to the technical field of passenger car assembling tools, and in particular relates to a rectangular pipe edger for passenger car frame welding. Background technique [0002] At present, most of the bus skeletons adopt full load-bearing structures, which are all welded by rectangular tubes. When the rectangular tube is butt welded to the rectangular tube, due to the small assembly gap of the rectangular tube, there is no penetration after grinding and smoothing after welding. Therefore, it is necessary to carry out edge processing on the two butted rectangular tubes, so that the welding surface of the rectangular tubes at the butt joint is concave. After the edge treatment, the butt weld has a good penetration, which improves the structural strength of the skeleton and improves the quality of the product. This tool overcomes the drawbacks of traditional skeleton welding using hammer percussion or no edging, and greatly improves ...
