Automatic tailor-welding device for loader hood

Abstract

The invention relates to the technical field of loader welding, in particular to an automatic tailor-welding device for a loader hood. The automatic tailor-welding device for the loader hood comprises an opposite tool table, the opposite tool table comprises a working platform, a sliding way and a two-way lead screw, half-section threads with opposite spiral directions are arranged on the two-way lead screw from the middle point to the two ends respectively, two movable platforms are slidably mounted on the slide way, and the automatic tailor-welding device for the loader hood comprises the automatic tailor-welding device, the automatic tailor-welding device comprises two single tailor-welding devices, each single tailor-welding device comprises a rotating shaft, a vertical plate, a lock foot adaptive clamping mechanism and a side plate adaptive clamping mechanism, and a supporting rod is hinged to the back side of each vertical plate. All the fixing tools can achieve three-degree-of-freedom adjustment and can be matched with locking feet of different structures to be positioned and welded to the bottom ends of the vertical plates in a tailor-welding mode, the tailor-welding angles on the two vertical plates are adjusted, and positioning holes in different positions of left side plate assemblies and right side plate assemblies of different models can be positioned.

Description

technical field [0001] The invention relates to the technical field of loader welding, in particular to an automatic tailor welding device for a loader hood. Background technique [0002] The hood is an important appearance part on the loader, and the hood is mostly a segmented structure, that is, the front, middle and rear hoods. Such as Figure 12 As shown, it is a schematic diagram of the loader hood of the present invention. The loader hood includes a left side panel assembly, a top panel assembly, a right side panel assembly, a right locking foot, an air conditioner mounting bracket and a left locking foot; the hood assembly is welded After completion, the three sections of the hood should be coordinated and beautiful as a whole after installation. Therefore, the hood tailor welding positioning device is an important link to ensure the accuracy of the overall forming position tolerance of the hood. The traditional tailor welding method is to use a simple tailor welding ...

AI Technical Summary

Problems solved by technology

[0004] (1) The device can only clamp a hood with a single shape. When it can only clamp a hood with a fixed angle between the left panel assembly and the right panel assembly, the splicing type is single, making the device Low utilization to accommodate design changes to more angles between left and right panel assemblies

[0005] (2) The position of the clamping assembly used to fix the locking feet cannot be adjusted, and the jig used to limit the locking feet cannot be changed, and cannot be adapted to different shapes of locking feet at any time

[0006] (3) The right support seat and the left support seat cannot adjust the hole positioning structure on the left side plate assembly and the right side plate assembly, and cannot adapt to the clamping of different types of hoods

[0007] (4) The device does not have components for clamping the air conditioner installation frame, and it is easy to deviate from the position of the air conditioner installation frame, which will affect the subsequent air conditioner installation

[0008] (5) The left panel assembly, top panel assembly, and right panel assembly are tailor-welded to form a semi-finished product with a U-shaped structure. This device can only tailor-weld the semi-finished product and the locking feet
