The left side of the inner surface of the adjusting seat 601 is rotatably connected to the accommodating seat 602, and the right side of the accommodating seat 602 is fixedly connected to a rotating column 603, the rotating column 603 penetrates and is rotatably connected to the right side of the adjusting seat 601, and a support bar 604 is fixedly connected to the top of the rotating column 603, and the left side of the support bar 604 is fixedly connected to a spring telescopic spring. Rod 605, the spring telescopic rod 605 will exert elastic force to push the top block 606 toward the support plate 609 under normal conditions, and the left end of the spring telescopic rod 605 is fixedly connected to the top block 606, and the material of the top block 606 is rubber. The outer surface of the spring telescopic rod 605 is movably sleeved with a top plate 607, and the top plate 607 can slide on the outer surface of the rod body of the spring telescopic rod 605. The right side of the top plate 607 is rotatably connected to the screw 608, and the screw 608 and the left side of the support bar 604 are threaded through. The rotating assembly 6 also includes a support plate 609, and a rubber layer is provided on the right side of the support plate 609 to increase friction. The support plate 609 is movably sleeved on the outer surface of the rotating column 603, and the support plate 609 is fixedly connected to the right side of the adjusting seat 601. A scale is provided on the support plate 609, and a pointer for pointing to the scale is provided on the rotating column 603.

[0024] When the above-mentioned equipment is used, a clamp is first set on the rotating disk 701 to fix the workpiece to be assembled. When the workpiece to be assembled needs to be flipped, the hydraulic push rod 2 is first started to drive the lifting seat 3 to rise, and then drive the connecting seat 5 to make the workpiece to be assembled installed on the clamp on the rotating disk 701 in the receiving seat 602 in the adjusting seat 601 rise, so as to reserve space for flipping. At this time, the adjusting seat 601 is driven to rotate by rotating the rotating column 603, thereby flipping the workpiece on the rotating disk 701 in the receiving seat 602. When the rotating column 603 rotates, it can drive the pointer to point to the engraved mark on the support disk 609. Degrees, in order to determine the flipping angle, the rotation of the rotating column 603 will drive the support bar 604 to make the top block 606 on the spring telescopic rod 605 rotate around the rotating column 603, at this time the top block 606 will push against the support disk 609 to apply friction to ensure the stability of the flipping.
