[0002] The automobile air-conditioning liquid storage dryer is an indispensable and important component in the automobile air-conditioning system. Its main functions include storing refrigerant, filtering impurities and absorbing moisture. These functions ensure the normal operation and high efficiency of the air-conditioning system. The liquid storage dryer can store a part of the refrigerant and perform gas-liquid separation to meet the needs of the air-conditioning system when the load changes. When the load is large, it can replenish the refrigerant; when the load is small, it can store excess refrigerant and make up for trace leakage. The left and right shells of the automobile air-conditioning liquid storage dryer wrap the internal components. During installation, the left and right shells are docked and installed. Most automobile air-conditioning liquid storage dryers are made of aluminum alloy and are heavy. Manual installation will bring a burden to the general staff. Utility Model Content

[0021] See also Figure 1-2 , the utility model provides a technical solution: an automatic assembly device for automobile air-conditioning liquid storage dryer, comprising;

[0022] Two symmetrical receiver-dryer support assemblies, each of which includes a positioning shaft 100, a gear 101, a guide tube 200, a telescopic rod 300, and a rack 400;

[0023] Each set of the receiver-drier support assembly includes two guide tubes 200, which intersect to form a cross shape. The two guide tubes 200 intersect to form a cross shape, so that the two guide tubes 200 can be rotated to adjust the distance and height of the ends of the two guide tubes 200. The positioning shaft 100 passes through the two guide tubes 200 and is rotatably connected thereto.

[0024] The two ends of the guide tube 200 are hollow structures. A telescopic rod 300 is embedded in each end of the guide tube 200. The telescopic rod 300 is slidably connected to the guide tube 200, and a bracket 302 is mounted on one end of the telescopic rod 300 by screws. A chuck 303 is provided on one end of the bracket 302.

[0025] Two gears 101 are sleeved on the outside of the positioning shaft 100, and two racks 400 are provided on the side of each guide tube 200. When one of the telescopic rods 300 is pulled, the fixed rod 301 at the end moves accordingly, and the fixed rod 301 pushes the rack 400 to move. One of the racks 400 drives the gear 101 to rotate, and drives the other rack 400 to translate through the gear 101, so that the two racks 400 move in opposite directions, and then when one of the telescopic rods 300 is extended or retracted, the other telescopic rod 300 is extended or retracted synchronously.

[0026] Furthermore, the gear 101 is sleeved on the outside of the positioning shaft 100 and is rotatably connected to the positioning shaft 100 .

[0027] Furthermore, the rack 400 is in an "L" shape, and symmetrical guide grooves 201 are provided at both ends of the guide tube 200. One end of the telescopic rod 300 has an integrally fixed fixed rod 301, which passes through the guide groove 201 and is fixedly connected to the rack 400, and the fixed rod 301 is slidably connected to the guide tube 200 through the guide groove 201.

[0028] Furthermore, the two racks 400 are buckled up and down on the outside of the gear 101 , and a plurality of tooth grooves are formed on the racks 400 , and the tooth grooves on the racks 400 are engaged with the gear 101 .

[0029] Furthermore, a groove is provided on the inner side of each guide tube 200, and the grooves of every two guide tubes 200 are cross-fitted, so the structure of the two guide tubes 200 is more compact, and the two sides of the two guide tubes 200 are flush after being cross-fitted.

[0030] Working Principle: The two guide tubes 200 intersect in a cross shape. Therefore, the two guide tubes 200 can be rotated to adjust the spacing and height of the ends of the two guide tubes 200. The telescopic rod 300 can be extended and retracted inside the guide tubes 200, making the adjustable range of the ends of the multiple chucks 303 wider. The protrusions on the chucks 303 correspond to the grooves on the liquid storage dryer. The liquid storage dryer support assembly surrounds both sides of the liquid storage dryer, lifts the left and right shells of the liquid storage dryer and docks them, thereby assisting workers in assembly operations.

[0031] Furthermore, when one of the telescopic rods 300 is pulled, the fixed rod 301 at the end moves accordingly, and the fixed rod 301 pushes the rack 400 to move. One of the racks 400 drives the gear 101 to rotate, and the gear 101 drives the other rack 400 to translate, so that the two racks 400 move in opposite directions, and then when one of the telescopic rods 300 is extended or retracted, the other telescopic rod 300 is extended or retracted synchronously.
