Manual tray carriage welding device

Abstract

The invention provides a manual tray carriage welding device, which comprises a base and an auxiliary installing base, wherein the base is in horizontal arrangement, the auxiliary installing base is positioned in the middle position of one side of the base and vertically and upwards extends, an x-direction positioning clamping module of a cargo fork of a manual tray carriage, a y-direction positioning clamping module of the cargo fork, a z-direction positioning clamping module of the cargo fork, a positioning clamping module of a top cover of the manual tray carriage and a positioning clamping module of a middle gear of the manual tray carriage, a positioning clamping module for a long shaft sleeve and a triangle of the manual tray carriage and a tooling mechanism of a back cover plate of the cargo fork are arranged on the base and the auxiliary installing base. The manual tray carriage welding device adopts the methods such as automation control technology, structural optimization design and space topology optimization for building the work procedure integration type manual tray carriage flexible welding device, the welding processing work procedures of the manual tray carriage are reduced, the processing site area is reduced, the production efficiency and the processing quality of the welding processing of the manual tray carriage are improved, the welding processing specifications of the manual tray carriage are increased, and the worker number and the work intensity are reduced.

Description

Technical field [0001] The invention relates to a welding device, in particular to a welding device of a manual pallet truck. Background technique [0002] In recent years, the welding equipment in developed industrial countries has developed rapidly. The automated welding equipment produced has developed in the direction of flexible manufacturing systems. Advanced automatic control systems, intelligent control systems and network control systems have been adopted, and welding robots have been widely adopted. As an operating unit, it constitutes a welding center, welding production line, flexible manufacturing system and integrated manufacturing system. At present, the key technologies of robotic welding production lines are mainly monopolized by Japanese, German, and American companies. After entering the 1980s, the completeness, automation, precision, and manufacturing quality of my country's welding equipment have been improved to varying degrees, but there are generally poor...

AI Technical Summary

Problems solved by technology

At the same time, most of the parts of the manual pallet truck are special-shaped sheet metal parts, the inner space of the triangle is narrow, and there is a dead zone during the welding process. Therefore, in the end, several manual repair welding processes are generally required to complete all the welding of the manual pallet truck. processing

[0006] From the analysis of the current organization and production mode of multi-process welding and processing manual pallet trucks, there are the following limitations: (1) The positioning reference is not uniform, which affects the processing accuracy and processing quality

The welding process of manual pallet truck requires multiple processes to complete, and the positioning reference of each process is difficult to be completely unified with the design reference, and there is a certain positioning error between each process

(2) Low production efficiency

When multi-process welding and processing manual pallet trucks, each process needs loading and unloading, positioning and clamping, welding processing, etc., which requires a lot of auxiliary time and low production efficiency.

(3) Labor-intensive, labor-intensive, poor working environment

The production method of multi-process completion of manual pallet truck welding processing requires more operators to participate. Operators need to continuously carry and turn over hundreds of manual pallet trucks every day. The labor intensity is very huge. At the same time, the harmful gas generated by welding processing Possess certain hazards to the health of operators

(4) The flexibility of the welding processing equipment is not enough, and the site area is large

The welding process of multi-process manual pallet truck requires more production links, the production chain is long, and the required site area is large

At the same time, the existing production equipment can often only complete the welding process of a single specification manual pallet truck, and the demand for the use of the site area is even greater
