Embodiment Construction

[0022] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown, a hydraulic shock absorber seat assembly welding tool, the hydraulic shock absorber seat includes seat plates 9 on both sides and a cover plate 10 welded between the seat plates 9 on both sides, the assembly welding tool It includes a bottom plate 1 and a vertical plate 2 that are fixedly connected in an L-shape. Both the bottom plate 1 and the vertical plate 2 are Q235B steel plates with a thickness of 20 mm. The upper surface of the bottom plate 2 is processed with a horizontal vertical plate installation groove 11. The vertical plate installation groove 11 is a through groove provided on the upper surface of the bottom plate 1 in the left-right direction, and the vertical plate 2 is welded and connected in the vertical plate installation groove 11 on the bottom plate 1; the upper surface of the bottom pla...

Abstract

The invention belongs to the technical field of welding tools. An installing and welding tool for a hydraulic shock absorber seat comprises a bottom plate and a vertical plate, wherein two rows of longitudinal assembling grooves are processed in the bottom plate, the bottom ends of seat plates are separately placed in seat plate assembling grooves on corresponding sides on the bottom plate, two rows of vertical limiting grooves corresponding to the two rows of longitudinal assembling grooves are processed in the front end surface of the vertical plate, and the back ends of the seat plates leanagainst the vertical limiting grooves on the corresponding sides of the vertical plate, separately; a cover plate assembling groove is also processed between the two rows of seat plate assembling grooves in the bottom plate, two sides of the cover plate assembling grooves communicate to the seat plate assembling grooves, and cover plates are placed in the cover plate assembling grooves; and two positioning grooves are also processed in same longitudinal positions on the upper surface of the bottom plate, the bottom plate is fixedly connected to columns through the positioning grooves, a crossbeam is connected between the two columns on the bottom plate, the lower end of the cross beam is fixedly connected to a rib plate, and two side faces of the rib plate are in separately contact withthe inner side face of the seat plate on the corresponding side of the hydraulic shock absorber seat. The tool can guarantee the flatness, the linearity and the weld joint quality of a product.

Description

technical field [0001] The invention belongs to the technical field of welding tooling, in particular to a welding tooling for a hydraulic shock absorber seat of a JW4G working vehicle bogie in Baoji Times. Background technique [0002] Baoji Times JW4G work truck bogie hydraulic shock absorber seat is an asymmetric open structure composed of two seat plates and a cover plate. The material is Q345B low carbon steel, and the cover plate is welded with a 45° bevel. Due to the large thickness of the plate during welding, single-sided open V-groove butt welding is adopted, and multi-layer multi-pass welding is used to reduce welding deformation. The hydraulic shock absorber seat has high design requirements. Its shape and position tolerances are within 1mm of flatness and verticality, within 1mm of linear tolerance, and within 0 to 1mm of internal gear size. The strict requirements lead to the group error not meeting the technical requirements. In order to realize the welding ...
