Specific implementation mode

[0020] As shown in the figure, the utility model is an assembly tool for a cooling module of an agricultural machinery radiator, which includes a side bracket 14 and an end bracket 16 installed on a workbench. A gas spring 8 is installed on one side of the side bracket. One end of the gas spring is fixed on the side bracket, and the other end is installed on the steel frame 1. A turning frame 7 is provided in the middle of the steel frame. A horizontal shaft 13 is provided at the top of the side bracket. The horizontal shaft is vertically fixed to the side bracket. The top of the turning frame is fixedly connected to the steel frame, and the bottom of the turning frame is sleeved on the horizontal shaft. The turning frame can rotate around the horizontal shaft. A steel frame foot 9 perpendicular to the steel frame is provided at the front end of the steel frame.

[0021] As Figure 2 shown, a cooling module 2 (including: water radiator, intercooler and oil radiator) is placed inside the steel frame. The steel frame is composed of two side frames, a rear frame and a bottom frame. A plurality of longitudinal rods are provided on the rear frame for positioning and preventing the cooling module from falling out. A bottom plate is placed on the bottom frame for placing the cooling module. Fixing plates 11 are respectively provided on the left and right sides inside the steel frame. The fixing plates can be integrally formed with the steel frame or fixed to the left and right side frames of the steel frame through fasteners. A long hole is provided along the length direction on the right fixing plate. A bolt passes through the long hole to install a positioning block 3, which is made of nylon square bar to prevent the product from being damaged. According to the different sizes of the cooling module, the positioning block can slide along the long hole and the positioning block is locked by a matching nut. Figure 2 Directly above in the middle is the positioning bottom corner part of the steel frame 1, and the two vertical surfaces are the positioning surfaces of the steel frame. Two groups of long holes are provided along the length direction on the left fixing plate and are arranged side by side. Each group of long holes consists of three long holes and is arranged in the upper, middle and lower positions. The upper long hole and the lower long hole 12 have the same length and shape; the short axis of the middle long hole 15 is larger than the short axis of the lower long hole. The upper long hole and the lower long hole are used to install the cylinder mounting seat 19. The cylinder mounting seat 19 is installed outside the left frame. The side cylinder 6 is arranged in the cylinder mounting seat 19. Its extending end extends out from the middle long hole and fixes the pushing block 17. The pushing block 17 is arranged inside the steel frame and is used to press the cooling module.

[0022] The end bracket 16 is arranged at the front end of the steel frame. A base 18 is provided at the top of the end bracket. The base is horizontally arranged and perpendicular to the end bracket. A long slot is provided on the base. The long slot is in the same direction as the steel frame. A fixing seat 20 is installed on the base. The fixing seat can move back and forth along the long slot. A cylinder assembly is installed on the fixing seat. Two groups of long slots identical to the fixing plate are provided on the fixing seat, that is, each group of long slots consists of three long slots and is arranged in the upper, middle and lower positions. The cylinder assembly includes a cylinder mounting seat 19, a top-mounted cylinder 4 and a push block 17. The top-mounted cylinder is installed on the cylinder mounting seat. The front end of the cylinder mounting seat is installed on the fixing seat 20 through matching bolts and nuts. The extending end of the top-mounted cylinder passes through the middle long slot and installs the push block 17. The pushing direction of the push block faces the steel frame. When a cooling module is placed on the steel frame, with the positioning angle as the vertex, under the combined action of the positioning block, the left push block and the front push block, the cooling module can be extruded. The positioning block 3, the top-mounted cylinder 4 and the side-mounted cylinder 6 can all move along the long slot to adapt to cooling modules of different specifications.

The positioning shaft 5-4 is installed in the middle of the lock seat. The lock rod 5-1 is horizontally arranged. A slot is provided at the front end of the lock rod. The slot can be stuck at the handle support leg 10 of the steel foot support 9. The middle of the lock rod is rotatably connected to the positioning shaft, that is, when the lock rod is pushed, the lock rod rotates around the positioning shaft. A spring 5-2 is provided behind the lock seat 5-3. One end of the spring is fixedly connected to the lock seat, and the other end is installed at the front end of the lock rod. When the lock rod 5-1 is pushed, the slot moves backward, the spring stretches, and the slot is separated from the handle support leg. The self-locking structure realizes self-locking by the spring returning to its original position, that is, when the frame is turned over and laid flat, the steel frame support legs are automatically held and locked to prevent the frame from rotating freely. When the foot touches the handle support leg of the self-locking structure and loosens, the steel frame can be turned over.

[0024] The working process of the utility model is as follows:

[0025] Adopt the steel frame reversible structure. Push the lock rod with the foot, the slot moves backward, the slot is separated from the handle support leg, the steel frame is turned over and erected, and the cooling modules are placed in order according to the process requirements. The pre-installed bolts at the frame connection are not tightened. After the steel frame is turned over and laid flat in the reverse direction, move the foot away from the lock rod, the spring resets, the self-locking structure locks the handle support leg on the steel frame support leg. After the inspection shows that the installation position size is qualified, the side-mounted and top-mounted cylinders simultaneously press the cooling module, tighten the bolts, then loosen the cylinders, and lift the assembled product to enter the next process.

[0026] Through pre-adjustment, this process realizes the assembly of cooling module frames of multiple specifications, with adjustable pressing force and automatic locking of frame flipping, achieving consistency, reliability, and safety in product assembly quality. During operation, it reduces the labor intensity of workers, has a stable production rhythm, and significantly improves production efficiency.
