Heavy-load type L-shaped hydraulic lifting welding positioner

Abstract

The invention belongs to the technical field of welding equipment, and relates to a heavy-load type L-shaped hydraulic lifting welding positioner. The welding positioner comprises a base, wherein box-type stand columns are fixed on the base, a frame-type lifting body is arranged on the surface of the box-type stand columns in a sliding mode, a heavy-load oil cylinder is installed on the bottom plate of the box-type stand columns, a piston rod end of the heavy-load oil cylinder is connected with the frame-type lifting body through an oil cylinder jacking fixing base, a turnover mechanism is arranged on the surface of the frame-type lifting body, a heavy-load cross arm is installed on the turnover mechanism, and the outer end of the heavy-load cross arm is provided with a slewing mechanism for slewing a workpiece. According to the positioner, the equipment is safer and more reliable, and the operation by workers is very convenient and simple.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and relates to a heavy-duty L-shaped hydraulic lifting welding positioner. Background technique [0002] At present, there are many L-shaped lifting welding positioners in China, including electric screw lifting type and hydraulic lifting type, but the lifting frame adopts linear guide rail and slider or front plate roller sliding type. This mechanism can be used under light load, but there is a great potential safety hazard under heavy load. The long horizontal arm and large workpiece have a large eccentricity and center of gravity distance, and there is a large impact load when lifting the workpiece. , so that the screws of the slider are broken, and the roller shaft of the front plate is cut off, causing the long cross arm and the workpiece to fall directly, which is very dangerous. Moreover, the motor wires on the existing L-shaped arms are all directly passed through the center ho...

Problems solved by technology

This mechanism can be used under light load, but there is a great potential safety hazard under heavy load. The long horizontal arm and large workpiece have a large eccentricity and center of gravity distance, and there is a large impact load when lifting the workpiece. , so that the screws of the slider are broken, and the roller shaft of the front plate is cut off, causing the long cross arm and the workpiece to fall directly, which is very dangerous

Moreover, the motor wires on the existing L-shaped arms pass directly through the center hole of the lifting frame, which affects the flip angle only to ±180 degrees, and the wires are easy to break, so the failure rate is relatively high
