[0032] Commonly used eccentric wheels are prone to falling and breaking when being placed, resulting in material waste. The placement of the compressor eccentric wheel is relatively difficult. When placing the compressor eccentric wheel, this device can adjust the first fixing rod 11 and the second fixing rod 13 according to the diameter of the compressor eccentric wheel, and the telescopic rod 14 can limit the compressor eccentric wheel to prevent the compressor eccentric wheel from falling and breaking.

[0033] The upper surface of the telescopic rod 14 is movably mounted with the eccentric shaft B portion 10, and the lower surface of the eccentric shaft B portion 10 is fixedly mounted with the eccentric shaft A portion 9. The diameter of the eccentric shaft B portion 10 is larger than the diameter of the eccentric shaft A portion 9. When the eccentric wheel of the compressor is placed, the lower surface of the eccentric shaft B portion 10 is movably mounted on the surface of the telescopic rod 14. After the placement is completed, the eccentric wheel of the compressor will not fall off at will. When the various components of the eccentric wheel of the compressor need to be replaced, they can also be directly replaced, which is convenient to operate.

[0034] A fixed rod moving groove 7 is provided on the side of the eccentric wheel placement frame 1, and a first fixed rod 11 and a second fixed rod 13 are movably mounted on the surface of the fixed rod moving groove 7. It is convenient for the user to adjust the first fixed rod 11 and the second fixed rod 13 to the diameter of the compressor eccentric wheel, so that the placement is more stable and not easy to fall.

[0035] The first handle 6 is fixedly mounted on one end of the first fixing rod 11 and the second fixing rod 13, and the second handle 12 is welded to the ends of the first fixing rod 11 and the second fixing rod 13. During the placement of the compressor eccentric wheel, the user can move and adjust the first fixing rod 11 and the second fixing rod 13 through the second handle 12 or the first handle 6, which is convenient to use.

[0036] Holes are provided at the four corners of the edge of the surface of the eccentric wheel placement frame 1, and the second support column 5 is fixedly inserted in the hole, and the first support column 2 is movably inserted on the lower surface of the second support column 5. The user can adjust the height of the eccentric wheel placement frame 1 to the ground by moving the second support column 5 up and down to adapt to the height of the compressor eccentric wheel. After determining the diameter and height, the overall device can realize the fixed placement of the compressor eccentric wheel, and the fixation is relatively firm.

[0037] A protective cover 8 is fixedly mounted on the upper surface of the second supporting column 5.

[0039] The implementation principle of the embodiment of the placement device of the eccentric shaft of the automobile air-conditioning compressor of the present application is as follows:

[0040] Commonly used eccentric wheels are prone to falling and breaking when being placed, resulting in material waste. The placement of the compressor eccentric wheel is relatively difficult. When placing the compressor eccentric wheel, this device can adjust the first fixing rod 11 and the second fixing rod 13 according to the diameter of the compressor eccentric wheel, and the telescopic rod 14 can limit the compressor eccentric wheel to prevent the compressor eccentric wheel from falling and breaking.

[0041] The diameter of the eccentric shaft B portion 10 is larger than the diameter of the eccentric shaft A portion 9. When the compressor eccentric wheel is placed, the lower surface of the eccentric shaft B portion 10 is movably mounted on the surface of the telescopic rod 14. After placement, the compressor eccentric wheel will not fall off at will. When the various components of the compressor eccentric wheel need to be replaced, they can also be directly replaced, which is easy to operate.

[0042] The user can adjust the height of the eccentric wheel placement frame 1 to the ground by moving the second supporting column 5 up and down to adapt to the height of the compressor eccentric wheel. After determining the diameter and height, the overall device can fix the compressor eccentric wheel and fix it more firmly.
