Large welding auxiliary device

Abstract

The invention relates to the technical field of welding assembly, in particular to a large welding auxiliary device which comprises a fixing base, inserting grooves are symmetrically formed in the top of a vertical plate, hydraulic cylinders are arranged in the grooves, a top plate is arranged above the vertical plate, inserting plates are arranged at the positions, corresponding to the inserting grooves, of the lower surface of the top plate, and T-shaped grooves are symmetrically formed in the bottom of the top plate. A T-shaped block is arranged at the position, corresponding to the T-shaped groove, of the upper surface of the cross beam, a hook is arranged on the lower surface of the cross beam, baffles are arranged on the upper surface of the fixing base close to the edges of the two sides, and clamping plates are arranged on one side faces of the baffles and connected with the baffles through a plurality of springs. A top plate of the device is stably matched with an inserting groove in a vertical plate in an inserted mode under the cooperation of an inserting plate, the height of the top plate is conveniently adjusted under the cooperation of a hydraulic cylinder, a cross beam is matched with a T-shaped groove in an inserted mode under the cooperation of a T-shaped block, the cross beam is conveniently pushed to move manually, the upper surface of a fixing base is matched with a baffle, and a clamping plate is connected with the baffle under the cooperation of multiple sets of springs. And weldments with different sizes can be conveniently clamped.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a large-scale welding auxiliary device. Background technique [0002] In the welding of metal parts, in the assembly process, multiple weldments need to be assembled. In the assembly process, the number of weldments is large, and the quality of some welds is relatively large. In some cases, vertical welding is required, and the welding The contact surface at the bottom of the part is small and cannot be erected vertically. For example, the main beam and the isolation bar of the highway isolation belt. The isolation bar cannot stand on the main beam for welding due to its small diameter and small contact surface at the bottom. It needs to be manually supported for welding. In this case, not only cannot it maintain stability during the welding process, but also the verticality is completely measured by visual inspection and a ruler, and its welding accuracy cannot be guaranteed. ...

[0002] In the welding of metal parts, in the assembly process, multiple weldments need to be assembled. In the assembly process, the number of weldments is large, and the quality of some welds is relatively large. In some cases, vertical welding is required, and the welding The contact surface at the bottom of the part is small and cannot be erected vertically. For example, the main beam and the isolation bar of the highway isolation belt. The isolation bar cannot stand on the main beam for welding due to its small diameter and small contact surface at the bottom. It needs to be manually supported for welding. In this case, not only cannot it maintain stability during the welding process, but also the verticality is completely measured by visual inspection and a ruler, and its welding accuracy cannot be guaranteed.

[0003] Therefore, when welding and assembling a large number of welding or large-scale weldments, the efficiency of manual welding is low, and the use of fully automatic welding equipment is unbearable for some small-scale manufacturers. How to improve efficiency through auxiliary equipment for parts or large parts, and at the same time ensure that each part is horizontal or vertical to improve welding accuracy has become an urgent problem to be solved
