Lifting manual pallet truck automatic welding device

Abstract

The invention provides an ascending and descending type manual tray carriage automatic welding device, which comprises a base, a position changing machine base and a welding robot, wherein the position changing machine case is positioned at one side of a tray carriage base, the welding robot is arranged at the other side of the tray carriage base, the tray carriage base is used for generally positioning the manual tray carriage, the position changing machine base comprises a tray carriage tooling frame for precisely positioning and tightly clamping the manual tray carriage, the tray carriage tooling frame is a frame body horizontally extending in front of the tray carriage tooling frame in a y direction, and in addition, the tray carriage tooling frame can drive the manual tray carriage to upwards and downwards move along the position changing machine base and to rotate. The ascending and descending type manual tray carriage automatic welding device has the advantages that the welding processing work procedures of the manual tray carriage are greatly reduced, the processing site area can be effectively reduced, the worker number and the work intensity are reduced, in addition, from the mechanical-electrical integration design idea, the limitation is overcome or reduced, and a scheme is provided for the automatic flexible welding of the tray carriage.

Description

technical field [0001] The invention relates to an automatic welding device, in particular to an automatic welding device for a lift-type manual pallet truck. Background technique [0002] In recent years, the development of welding equipment in industrially developed countries has been rapid, and the production of automated welding equipment has been 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 used. As an operating unit, it consists of a welding center, a welding production line, a flexible manufacturing system and an integrated manufacturing system. At present, the key technologies of robot welding production lines are mainly monopolized by companies in Japan, Germany, and the United States. After entering the 1980s, the completeness, automation, precision and manufacturing quality of welding equipment in our ...

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
