Description

Technical Field

[0001] The present invention relates to the technical field of component welding and fixing workbenches, and in particular to a workbench for component welding and fixing. Background Art

[0002] In the current situation of continuous technological development, automation technology has rapidly swept across all industries like a tide and plays an important role in promoting the development of the industries. For the traditional machinery manufacturing industry, the help brought by automation technology is particularly obvious. In the past, due to the uneven abilities of production workers in traditional machinery manufacturing, the production cycle and quality of its products were difficult to guarantee, which led to low production efficiency and huge energy consumption. By reasonably applying automation technology, while reducing labor costs, the product quality was improved, and the production cycle was greatly shortened, which also made many traditional machinery enterprises invest in the transformation and reform towards automated production.

[0003] In existing high-grade safes, the safety level of CEN4 series safes is higher than that of CEN3 series safes, and their production requirements are higher. The most obvious difference in CEN4 series safes is that the omega-shaped steel inside the CEN3 series safes is replaced by a steel bar grid. Its interior is a steel bar grid structure, and the steel bar grid on each inner sheet material surrounds the safe. This structure not only strengthens the fluidity of cement but also improves the safety performance of the safe. Therefore, it is very important to ensure the welding quality of the steel bar grid on each sheet material. When using welding equipment to perform component welding of the steel bar grid at present, due to the lack of fixation between the steel bar grid and the sheet material during the welding process, it is difficult to control the welding error, thus affecting the product quality. Therefore, there is an urgent need for a workbench that can fix both the sheet material and the steel bar grid at the same time. Summary of the Invention
