Side open type carriage welding turnover work center

Abstract

The invention discloses a side open type carriage welding turnover work center belonging to automobile crane carriage welding displacement equipment. The turnover center comprises a side open welding positioner, a three-dimensional feeding trolley, a lifting platform and an electric control system, wherein the three-dimensional feeding trolley is located in the middle of the side open welding positioner, the lifting platform is arranged in front of the side open welding positioner, the three-dimensional feeding trolley is arranged on rails which are perpendicular to the side open welding positioner, and the electric control system is simultaneously connected with the three-dimensional feeding trolley, the lifting platform and the side open welding positioner. The side open type carriage welding turnover work center has the advantages that firstly, two side open tilters commonly use one feeding trolley, thus the turnover work center is compact in structure, secondly, the lateral faces of the tilters are open for realizing the positioning of work-pieces, thirdly, the work-pieces can be automatically clamped, and production efficiency are high, fourthly, 180-degree idle rotation can be realized in a turnover ring, which realizes the requirement that carriages are positively fed and reversely discharged, and fifthly, welding operations of workers are convenient.

Description

technical field [0001] The invention relates to a frame welding and displacement device of an automobile crane, in particular to a side-opening type frame welding and turning work center. Background technique [0002] At present, there are two main forms of using the frame ring type turning machine. The first form is used for turning over the rear section of the vehicle frame. The special machine is mainly composed of driven rollers, driving rollers, hinges, lock seats, support wheels, drive motors, clamping mechanisms and other components. The overturning circle is divided into upper and lower half circles. There is a hinge point in the middle of the overturning circle. The upper half circle can rotate horizontally around the hinge point. When opening, the spring pin in the artificial lock seat is pulled down, pushing the upper and lower half circles apart. The upper and lower half circles of this form are connected together by the hinge point and the lock seat. After the...

Problems solved by technology

The combination of this form of turning circle is made of tapered pins for positioning and fastening with bolts. Although this turning circle can realize the front and back of the workpiece, the opening and closing of the turning circle must use the driving and wrench, so this turning The opening and closing of the ring is cumbersome, requires a lot of equipment, the opening and closing time is relatively long, and the labor intensity of the workers is high; on the other hand, the clamping of the workpiece is completely done manually, which is not efficient and the labor intensity of the workers is high.
