Double-arm automobile frame turnover device

Abstract

The invention discloses a double-arm automobile frame turnover device and relates to the field of automobile manufacturing. The double-arm automobile frame turnover device comprises two turnover arms,a hydraulic control system and angle limiting blocks, wherein each turnover arm comprises two bearing pedestals and an oil cylinder support seat; bearings and L-shaped turnover support plates comprising long arms and short arms are mounted on the bearing pedestals; the L-shaped turnover support plates are articulated with the bearing pedestals; the bottom ends of the oil cylinder support seats are articulated with cylinder seats of oil cylinders; piston rods of the oil cylinders are articulated with the long arms; the piston rods extend and contract to drive the L-shaped turnover support plates to turn over along rotating shafts; the long arms are positioned by the top surfaces of the oil cylinder support seats in a turnover process; and the short arms are positioned by the angle limitingblocks. The double-arm automobile frame turnover device can solve the problems that swing of an automobile frame exists in a turnover process when the automobile frame is required to be turned over in an automobile frame production process, the automobile frame cannot be stopped stably in a required angular position, the operation is complicated, many persons are required, potential safety hazards exist, and a production rhythm cannot be met due to low efficiency caused by operation of hook replacement, frequent ascending and descending of a crane and the like.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a device suitable for 0-90 degree turning of large workpieces such as vehicle frames in the automobile production process. Background technique [0002] In the production process of the automobile frame, due to the large size of the frame workpiece, it is difficult to turn over. At present, the manual operation of the crane is basically used to turn the frame 90 degrees to meet the production requirements. If the powder spraying and drying process is required in the production process of the frame, the frame needs to be turned 90 degrees in this process section. The four hooks of the crane are manually hung on the frame, and the frame is placed on the sleeper by the crane. Operate the crane to loosen the hook and remove the outer hook, hang it on the inner hook, and then lift the frame by the crane, and turn it directly to 90 degrees. In this way, the frame is tu...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a double-armed vehicle frame overturning device, which can solve the problem that the vehicle frame needs to be overturned during the production process of the automobile frame, and there is a problem that the vehicle frame swings during the overturning process and cannot be rotated at the required angle. (1-90 degrees) position to stop stably, complex operation by employees requires many people to carry out and there are potential safety hazards, replacement of hooks, frequent lifting and lowering of cranes and other operations lead to low efficiency and cannot meet the production rhythm.
