A workpiece turning device

Abstract

The invention discloses a workpiece turnover device, and relates to mechanical equipment, in particular to the workpiece turnover device for overturning assembled T-shaped or H-shaped steel and several special cylinders and pipes with greater outer diameters and weights and shorter lengths by 0-180 degrees and applied to overturning movement of movable workpieces, in particular applied to such stations as welding turnover, correcting turnover, assembling turnover, flaw detection and manual welding. The workpiece turnover device comprises a base and a frame; the frame includes a fixed frame and a movable frame; the fixed frame is fixed on the base; the movable frame is movably connected with the base through a guide rail; an L-shaped first rotating arm is rotationally connected with the fixed frame through a rotating shaft A; and an L-shaped second rotating arm is rotationally connected with the movable frame through a rotating shaft B, and can perform a translational motion along with the movable frame. The workpiece turnover device has the advantages of safety, light turnover, difficult workpiece damage and deformation, low labor intensity of workers and high production efficiency.

Description

technical field [0001] The invention relates to mechanical equipment, especially for T-shaped or H-shaped steel after assembly and some special outer diameters, larger weights, shorter length cylinders, 0° to 180° flipping of pipelines, and moving workpieces The overturning movement is especially applied to the workpiece overturning device on welding overturning, correcting overturning, assembly overturning, inspection flaw detection, manual welding and other stations. Background technique [0002] Generally, enterprises generally use cranes to pull or hang obliquely to turn over large workpieces. However, inclined cranes are illegal operations and have great potential safety hazards. Secondly, during the oblique hanging and overturning process, the force on the obliquely pulled part of the workpiece is uneven during the overturning process, and the force suddenly increases sharply at the moment of overturning, resulting in the workpiece being easily damaged and deformed.

Problems solved by technology

[0002] Generally, when turning over large workpieces, enterprises generally use cranes to pull or hang them obliquely to turn over workpieces. However, inclined cranes are illegal operations and have great potential safety hazards.

Secondly, during the oblique hanging and overturning process, the force on the obliquely pulled part of the workpiece is uneven during the overturning process, and the force suddenly increases sharply at the moment of overturning, resulting in the workpiece being easily damaged and deformed.

Furthermore, it is time-consuming and labor-intensive to hang the vehicle obliquely, which is very inconvenient
