H-shaped steel turnover welding device

Abstract

The invention relates to an H-shaped steel turnover welding device which comprises stand columns, a rotary frame, a locating and locking device, a lifting device and a limiting device. The locating and locking device comprises a locking mechanism on the stand columns and a frame locating frame which is fixedly connected to the rotary frame and matched with the locking mechanism, the lower portion of the lifting device is connected with a height adjusting device, the vertical movement range of a column foot plate and an upper top plate can be adjusted within a large range, and therefore the located profiled steel length range is wider. The mode of pushing a locating shaft through an air cylinder piston rod is adopted in the locating and locking device, and compared with a manual mode, an operator only needs to carry out operation through a control switch, and the operation is more convenient. In the limiting device, electromagnetic suction cups and limiting plates are used in cooperation, the limiting function is achieved, meanwhile, the locating function is achieved, when a locating position is inaccurate, the accurate position can be found out by adjusting an adjusting screw rod, and the problem that adjustment is inconvenient if deviation occurs after locating hole locating mounting is adopted is solved.

Description

technical field [0001] The invention relates to the technical field of section steel processing equipment, in particular to a welding equipment for H-section steel column feet in the three-dimensional garage industry. Background technique [0002] In the three-dimensional garage industry, H-shaped steel is used as the main supporting member. It is necessary to weld the column foot plate at the lower end of the H-shaped steel column and weld the top plate at the upper end. In the past, the welding was mainly performed manually. The positioning accuracy is low and consistent when using manual placement. poor performance, and takes up more labor resources, which increases the production cost. At the same time, the manual positioning operation is troublesome, takes a long time, and the production efficiency is low. Therefore, it cannot meet the needs of large quantities of H-shaped steel in the three-dimensional garage industry. Welding the base plate requires welding the top pl...

Problems solved by technology

The main disadvantage is that the lifting device can only lift and lower, and cannot be adjusted, which limits the processing range of the equipment

In addition, the disadvantage of the above technical solution is that: the positioning and locking device is manual, which is not easy to operate; the positioning and locking device is only positioned through the positioning hole, and it is not easy to adjust if there is a deviation after installation
