[0023] The flip base plate 6 is the main body of the assembly load, which is made of 500X160 20mm thick steel plate and supported by the support frame 10. The bracket is made of 25mm steel plate, fixed on both sides of the flat plate by bolts, and connected to the worm gear mechanism 9 by the transmission shaft 7, and the worm gear mechanism 9 is driven by the rotating handle 8 to drive the flip base plate 6 to rotate to realize the function of different assembly angles. Its main components are the first locating pin 1, the second locating pin 2, the first support block 3, the locating block 4, the second support block 5, the flip base plate 6, the transmission shaft 7, the crank handle 8, the worm gear mechanism 9, the support frame 10, the equipment tooling base plate 11, the clamping mechanism 12, the flip frame support frame 13, and the connecting block 14. The components are positioned by the locating pins and the locating block 4 of the flip base plate 6. The type of machine model is identified during the clamping process by the first locating pin 1 and the second locating pin 2. The corresponding machine model products are separated by the different positions of the locating pins on the flip base plate 6. In addition, two models can be assembled at the same time during its operation. The components are clamped and fixed by the clamping mechanism 12 to prevent the workpiece from falling off. The worm gear mechanism 9 is moved by the crank handle 8. The different positions are changed by the rotation of the flip mechanism to ensure the completion of the assembly work.

[0024] The bearing component includes a flip bottom plate 6 , on which a first support block 3 and a second support block 5 are fixedly mounted by bolts. A positioning block 4 , a first positioning pin 1 , and a second positioning pin 2 are also mounted on the flip bottom plate 6 .

[0025] The first positioning pin 1 and the second positioning pin 2 are made of cylindrical pins with a diameter of 10 mm and are used to distinguish different models.

[0026] The first positioning pin 1, the second positioning pin 2, the positioning block 4, the first supporting block 3, the second supporting block 5, and the clamping mechanism 12 are installed at corresponding positions of the flip bottom plate 6 according to the measured dimensions by measuring the positions of the positioning points.

[0027] The support frame 10 is used to support the worm gear mechanism 9 .

[0028] The transmission shaft 7 connects the worm gear mechanism 9 and the flip base plate 6 .

[0029] The crank handle 8 is mounted on the worm gear mechanism 9. The worm gear mechanism 9 is driven by rotating the crank handle 8, thereby driving the transmission shaft 7 to rotate the flip base plate 6.

[0030] When the positioning is completed, the workpiece is clamped by using the clamping mechanism 12 to complete the positioning and clamping, so that it is not easy to fall off during the turning process.

[0031] It can carry parts of various models without matching fixtures of various models. It can reduce the tedious work of preparing various tools during engine assembly by virtue of its tooling process characteristics, reducing the complexity of the work. Moreover, it can assemble two models at the same time. It uses the characteristics of its own locating pins in different positions of the flip base plate to achieve the function of hardware differentiation. At the same time, it can also control the 6 degrees of freedom of the parts to fix them on the fixture plate, and control their prescribed movement through the flip mechanism to complete the assembly content.
