High-accuracy hydraulic scraper pan assembly tooling

Abstract

The invention relates to a high-accuracy hydraulic scraper pan assembly tooling, comprising a tooling base, a pan baseboard tire mould, a pair of beams moving towards each other along the base, a first jacking cylinder, a second jacking cylinder, a first hydraulic cylinder, a pan bottom guard board turnover support, an ear plate group positioning and clamping device and a lateral knife board jacking mechanism, wherein when the scraper pan is buckled on the pan baseboard tire mould, the pan bottom guard board turnover support turns over and then positions an ear plate group through the ear plate group positioning and clamping device; and the first jacking cylinder, the second jacking cylinder, the first hydraulic cylinder and the lateral knife board jacking mechanism simultaneously jack a bottom guard board, a master knife board, a pall wall board and a lateral knife board of the scrapper pan. In the invention, a fixture combining hydraulic pressure and pneumatics is used to clamp and position a scraper pan assembly, thereby ensuring high accuracy and stable and reliable quality of the scraper pan assembly, preferably improving the welding quality of products, and completely meeting the welding requirements of robot weld joints. Meanwhile, the labor intensity of workers is low, and the assembly efficiency is high.

Description

technical field [0001] The invention relates to a high-precision bucket hydraulic assembly tooling. Background technique [0002] Buckets are generally installed on excavators, loaders, etc., and are also called buckets. They mainly include: bucket bottom guard plate, ear group plate, bucket wall plate, main knife plate, side knife plate and other components assembled and welded. Generally, the buckets of commonly used construction machinery loaders are mostly welded by robots. However, the original bucket assembly tooling is mainly completed manually. The assembly accuracy is poor, and the weld seam gap is large, which cannot meet the requirements of robot welding; at the same time , Due to the large volume of the bucket, it will inevitably result in high labor intensity and low efficiency, requiring 3 to 4 people to cooperate to complete. Contents of the invention [0003] The invention provides a high-precision bucket hydraulic assembly tooling. [0004] In order to a...
