[0002] In the automobile manufacturing process, the intercooler, radiator and condenser in the cooling system are generally purchased and sent to the line separately. First, the upper and lower crossbeams of the water tank frame are installed on the positioning fixture, and the hood lock and other accessories are installed. Then the assembled water tank frame is transferred to the subassembly hanger. The steering radiator and condenser are assembled on the subassembly workbench, and the assembled parts are assembled to the water tank frame. After the radiator, fan cover, headlight bracket and other parts are installed on the front and back sides of the frame in turn, the subassembly hanger is finally used to send the assembly to the corresponding assembly station to complete the connection with the car body. The whole process involves many assembly parts, a large site area, and many subassembly tools and assembly stations.

There is a group of positioning and mounting holes 1-6 on its upper surface, which are used to position and fix the locking device 2-11 and the rotating bearing 2-13. Four groups of moving wheels 1-3 are arranged at the diagonal position at the bottom of the lower frame 1-1, of which two groups on the same side are self-locking universal wheels, which are used to realize the flexible movement of the tooling and fixation during the operation process; the boss 1-4 is welded and fixed to the lower square tube on the left side of the lower frame 1-1, and is used to connect the fixed plate 2-2; the positioning plate 1-5 is welded on the support platform 1-2, and is used to fix the flipping mechanism mounting seat 2-4;

[0041] Please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 The flipping mechanism 2 is mainly used to realize the flipping of the sub-packaging positioning platform. The flipping pedal 2-1 is used to step on and control the flipping of the sub-packaging positioning platform, and is connected to the fixed plate 2-2 through a pin shaft and a cotter pin; the fixed plate 2-2 is fixed to the boss 1-4 by bolts; the connecting rod 2-3 is connected to the flipping pedal 2-1 and the telescopic rod 2-6 through a pin shaft; the mounting seat 2-4 is fixed to the positioning plate 1-5 by 4 hexagon socket screws; the telescopic rod 2-6 passes through the guide holes of the upper and lower brackets of the mounting seat 2-4 and the compression spring 2-5 to ensure that the telescopic rod 2-6 moves vertically up and down. The compression spring 2-5 is sleeved on the telescopic rod 2-6, and the lower end is supported on the upper surface of the lower bracket of the mounting seat, and the upper end is supported on the washer connected to the telescopic rod 2-6 to limit the excessive downward movement of the telescopic rod 2-6 and After compression, it provides power for upward movement; the connecting shaft 2-12 connects the flip handle 2-7 and the fixed plate 2-8, and 4 groups of card slots 2-9 and pin holes 2-10 are evenly distributed on the fixed plate 2-8. The connecting shaft 2-12 passes through the rotating bearing 2-13 to realize support and rotational movement. The rotating bearing 2-13 and the locking device 2-11 are fixed on the support platform 1-2, and the locking device 2-11 is used in conjunction with the fixed plate 2-8; the connecting bracket 2-14 is used to connect the rotating shaft 2-11 and the subassembly positioning platform 3, and a limiting plate 2-15 (which can be a plate covered with rubber on the surface) is arranged thereon to limit the shaking of the flipping platform during the flipping process, and to provide assistance for the limiting fixation of the flipping platform.

[0042] The flipping process is as follows: step on the flip pedal 2-1, the connecting rod 2-3 moves downward, thereby driving the telescopic rod 2-6 to move downward, the compression spring 2-5 is compressed downward, the telescopic rod 2-6 is disengaged from the slot 2-9 on the fixed plate 2-8, turn the flip handle 2-7, the fixed plate 2-8 and the sub-packaging positioning platform 3 are flipped 90° together, the compression spring 2-5 releases the compression force, the telescopic rod 2-6 moves upward to clamp the next slot on the fixed plate 2-8, and the sub-packaging positioning platform is flipped. The locking pin of the sliding locking device 2-11 is inserted into the pin hole 2-10 on the fixed plate 2-8, thereby fixing the flipping platform.

[0043] In some preferred embodiments, ergonomic grooves or soft material wrapping may be added to the handle surface, so that the operator can hold the handle more firmly and comfortably for operation.

[0044] Please refer to Fig. 9 , the subassembly positioning platform 3 is used to realize the positioning during the assembly process of parts. The movable frame 3-1 is a square steel structure, forming a supporting skeleton; the positioning block assembly 3-2 is arranged on the movable frame 3-1, including: an upper beam positioning block 3-6 arranged on the middle support beam 3-11 of the movable frame 3-1, a headlight bracket positioning block 3-8, a lower beam positioning block 3-7 and a group of positioning bracket positioning blocks 3-9 symmetrically arranged on both sides connected by positioning brackets 3-3; the above positioning blocks all include positioning holes and positioning pins, and the positioning pins 3-5 are used in conjunction with the positioning holes 3-4 (the parts at the corresponding positions on the front-end module have matching pin holes for matching positioning) to fix the position of the parts. To ensure the positioning accuracy of parts; in some embodiments, for example, for a specific vehicle model, the upper beam positioning block 3-6, the headlight bracket positioning block 3-8, the lower beam positioning block 3-7 and the positioning bracket positioning block 3-9 can be designed as fixed positions corresponding to the parts on the front-end module of the vehicle model; for situations not targeting specific vehicle models, the upper beam positioning block 3-6, the headlight bracket positioning block 3-8, the lower beam positioning block 3-7 and the positioning bracket positioning block 3-9 can be designed to be able to slide on the flip frame beam 3-11 or the movable frame 3-1 to adapt to the front-end modules of different vehicle models.

[0045] During the assembly process, the positioning error of the parts is monitored in real time. If the positioning error is found to be beyond the allowable range, the error can be corrected by adjusting the position of the positioning block (for example, by equipping the positioning block with an adjustable bolt) or by using a compensating gasket to ensure the consistency of the assembly.

[0046] In some preferred embodiments, when installing components with high precision requirements such as headlight brackets, a laser positioning device is used to assist in positioning, and the precise position of the components is determined by a laser beam, thereby further improving the positioning accuracy.

Thus, the upper and lower beams of the cabin are turned to the vertical direction, and assembled on both sides of the upper and lower beams of the cabin. There are more parts on the front side, which are divided into three sequences, namely, the first sequence of front-end module assembly, which mainly assembles the steering radiator assembly, the motor radiator assembly and its pipelines, and tightens and fixes them according to the positioning position; the second sequence of front-end module assembly, which mainly assembles the positioning condenser assembly and its pipelines, and fixes them with bolts; the third sequence of front-end module assembly, uses the headlight bracket positioning block 3-8 and the positioning bracket positioning block 3-9 to fix the left and right headlight brackets on this device, and then fixes the headlight brackets to the upper and lower beams of the cabin;
