Problems solved by technology

Therefore, at present, the welding process of manual pallet trucks mainly adopts the method of welding robot + manual repair welding to organize production, that is, for the first few procedures, the company develops some welding equipment by itself, adopts manual positioning and clamping, and then performs automatic welding by welding robots ,like Image 6 The fork 32 shown in the figure is welded with the middle gear 31, the triangle 24 is welded with the fork 32, the triangle 24 is welded with the top cover 27, and the long shaft sleeve 25 is partially welded, etc., but for some limited space, it is difficult to use welding robots for automatic welding The welding seam needs to be completed by manual repair welding, and these repair welding processes are the last few processes. The manual pallet truck has basically formed, and the weight of each manual pallet truck is about 30kg. Workers need to constantly flip the manual pallet truck to Complete the repair welding work, the labor intensity is very huge
[0004] It can be seen that the current repair welding process of manual pallet trucks has the following limitations: 1) The product quality is unstable and the production efficiency is low
At present, the repair welding process of manual pallet trucks is done manually, and the technical level, work attitude, and psychological state of the operators all affect the welding process quality, and the production efficiency is low.
2) Poor working environment and high labor intensity
Manual pallet truck welding generally uses CO 2 Gas shielded welding, the exhaust gas and dust generated during the welding process seriously endanger the health of welders. At the same time, operators need to constantly move and turn over hundreds of manual pallet trucks every day in order to have a better welding position for welding Processing, its labor intensity is very huge
3) Labor intensive, difficult to recruit and manage
At present, the repair welding process of manual pallet trucks requires 3 to 4 operators to complete the processing. With the rise of labor costs in China, the appreciation of the renminbi, and the deterioration of environmental and resource bottlenecks, China's low-cost advantages will gradually disappear, and there will be difficulties in recruitment and management. , it is difficult to complete the order task on time

Abstract

The invention discloses an automatic repair welding flexible positioner of a manual-operation pallet truck. An auxiliary foundation base is fixedly connected to one side of a foundation base, a y axis clamping cylinder is installed on the auxiliary foundation base, a lower rotation frame is rotatably connected onto the foundation base, one side of an upper rotation frame is rotatably connected with one side of the lower rotation frame away from the auxiliary foundation base, a worm wheel of a worm and gear pair is fixedly sleeved on an x axis rotation shaft, two electromagnetic chuck bases are symmetrically installed on the upper rotation frame, two electromagnetic chucks are fixedly installed on each electromagnetic chuck base, the electromagnetic chucks attract forks of the manual-operation pallet truck through electromagnetic force, two lower rotation frame limit devices are symmetrically installed on two sides of the foundation base, and two upper rotation frame limit devices are symmetrically installed on one side of the foundation base. The automatic repair welding flexible positioner of the manual-operation pallet truck is compact in structure, improves welding quality and production efficiency of the manual-operation pallet truck, reduces labor intensity of workers, improves working environment of the workers, and meets automatic repair welding processing requirements of the manual-operation pallet truck.

Description

technical field [0001] The invention relates to a flexible positioner, in particular to a flexible positioner for manual pallet truck automatic repair welding. Background technique [0002] Manual pallet truck is a simple and effective logistics handling equipment, which is widely used in various sectors of the national economy such as workshops, warehouses, stations, ports, airports, etc. It is an efficient equipment for loading and unloading and short-distance transportation. With the rapid development of the economy and logistics industry, the supply of manual pallet trucks has been in short supply. my country is a big country in the manufacture and consumption of pallet trucks, but its production mode is labor-intensive, with low technical content and low added value. With the deterioration of factors such as rising labor costs and RMB appreciation, my country's low-cost advantages will gradually lose, so how to It is imminent to speed up the technological transformation...
