Welding positioner for loader movable arm

Abstract

The invention relates to a welding positioner for a loader movable arm and belongs to the technical field of welding positioners. The welding positioner comprises a support truss, a pitch angle adjusting device arranged at the bottom of the supporting truss, a position changing table arranged on one side of the supporting truss, a displacement device and a cross beam positioning device. Two supporting platforms, two sets of movable arm plate fixing structures and driving structures are arranged at the top of the position changing table, the movable arm plate fixing structures and the driving structures are arranged at the tops of the two supporting platforms correspondingly, and the bottom of each supporting platform is in sliding fit with the position changing table. According to the welding positioner for the loader movable arm, the cross beam positioning device is arranged, a cross beam can be horizontally located between the two movable arm plate fixing structures through operation of the cross beam positioning device, the cross beam does not need to be fixed and supported manually, the labor cost of an enterprise is reduced, a large operable space is reserved for welding personnel, and a worker does not need to bend down and incline leftwards and rightwards to work.

Description

technical field [0001] The invention relates to the technical field of welding positioners, in particular to a welding positioner for loader arms. Background technique [0002] The loader is a kind of earthwork construction machine widely used in construction projects such as roads, railways, and buildings. The loader frame is equipped with buckets, rocker arms and booms, and the boom bears the load of the bucket. , is an important load-bearing component; such as figure 1 As shown, the loader arm includes a left boom plate 1, a right boom plate 11, and a box-shaped crossbeam 12 connecting the left and right boom plates. In the process of producing the boom, workers need to manually install the crossbeam 12 It is welded between the left movable arm plate 1 and the right movable arm plate 11. [0003] A welding positioner for the arm of a loader disclosed in the utility model with the reference application number CN202020008811.7, which includes a base and a boom; the upper ...
