Description

Technical Field

[0001] The utility model relates to the technical field of vehicle frame production equipment, in particular to a front vehicle frame turning tool for a loader. Background Art

[0002] When assembling the lower frame of a wheeled excavator, many parts need to be assembled on both the upper and lower sides. Therefore, the frame needs to be flipped during assembly to improve assembly efficiency. Currently, large wheeled excavator production companies use large assembly lines, relying on large cranes and assembly line slides to achieve flipping. However, small companies have insufficient investment in assembly equipment, and most of them only rely on cranes to achieve flipping during assembly, which is not only inefficient but also poses certain risks to personal safety during operation.

[0003] After searching, Chinese patent announcement number: CN210025203U discloses an excavator frame flipping device, which relates to the field of frame flipping technology. The utility model includes a main flipping machine, an auxiliary flipping machine, a support frame and a fixed frame. The main flipping machine and the auxiliary flipping machine are connected by a support frame. The support frame is a rectangular structure, and a fixed frame is fixed on each of the two opposite sides of the support frame; the fixed frame includes a fixed seat, a telescopic arm, a push rod, a support arm, a support rod and a limit rod. One surface of the fixed seat is connected to a plurality of telescopic arms, and the other end of the telescopic arm is connected to the push rod. Support arms are fixed on both sides of the telescopic arm, and one end of the support arm is connected to the support rod, and the support rod is connected to the limit rod through a positioning screw. The utility model provides support force for the support frame by setting an auxiliary flipping machine, thereby improving the stability of the flipping device, and fixes the frame around by the push rod and the limit rod on the support frame to prevent side slipping during subsequent operations, thereby improving operation safety.
