[0002] The compressor is generally composed of a body, a motor, a cylinder, a piston, a control device and a cooling system; the motor and the piston are usually connected by a crankshaft. The crankshaft includes a short shaft and a long shaft, wherein the long shaft is connected to the rotor of the motor, and the short shaft is connected to the piston through a connecting rod.

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0015] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.
[0016] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.
[0017] Combination Figure 1-4As shown, the processing rotating device includes a machine table 1, on which a rotatable rotating disk 2 is provided, and the rotating disk 2 is evenly provided with a plurality of notches 3 along the circumferential direction, and a carrier plate 4 is provided on each notch 3, and a pair of sleeves 5 are rotatably provided on the carrier plate 4, and a material sleeve 6 is provided above the sleeve 5, and a rotating mechanism for driving the sleeve 5 to rotate is provided in the machine table 1, and the rotating mechanism includes a fixed frame 7 installed in the machine table, and a pair of guide rods 8 are provided between the fixed frame 7 and the machine table 1, and a guide plate 9 is slidably provided between the two guide rods 8, and a pair of rotatable rotating shafts 10 are vertically provided on the guide plate 9, and a top shaft 11 matching the inner diameter of the sleeve 5 is provided on the top of the rotating shaft 10, and a lifting cylinder 12 is provided in the machine table 1, and the driving shaft of the lifting cylinder 12 is connected to the guide plate 9. The lifting cylinder 12 is fixedly installed in the machine table 1 through a mounting seat 13.
[0018] When the crankshaft is processed, a few products with minor defects will be produced. The staff will pick out the products with minor defects and process them into qualified products. During the processing, the crankshaft is driven to rotate by the rotating mechanism until the processing of the crankshaft is completed.
[0019] When the device is used to process the crankshaft, the crankshaft is first placed in the sleeve with the processing end facing upward, and then the rotating disk rotates one station, the sleeve with the crankshaft rotates to the processing position, and the processing mechanism is used to process the crankshaft processing end surface. In this process, the rotating shaft mechanism drives the sleeve to rotate at least one circle to change the processing position of the crankshaft, so that the processing of the crankshaft processing end surface is completed, and then the rotating disk continues to rotate one station, and the next sleeve with the crankshaft rotates to the processing position to wait for processing.
[0020] When the sleeve is driven to rotate by the rotating mechanism, the sleeve with the crankshaft rotates to the processing position, and the lifting cylinder first drives the guide plate to move upward for a short distance, and the pair of rotating shafts on the guide plate move toward the bottom of the sleeve. Until the two top shafts are respectively inserted into the corresponding sleeves, and the top of the top shaft is against the sleeve, and finally the two rotating shafts rotate at the same time, thereby driving the sleeve to rotate.
[0021] In the embodiment, there are four carrier plates, each of which is rotatably provided with a sleeve, and a material sleeve is provided on the sleeve, which can greatly improve the processing efficiency of the crankshaft. When any of the material sleeves rotates to the processing position, the processing mechanism on the processing position processes the crankshaft on the material sleeve.
[0022] As a preferred structure, a rotating gear 14 is connected to the bottom of the rotating shaft 10 , and a rotating motor 15 is also provided on the fixing frame 7 . An intermediate gear 16 is connected to the driving shaft of the rotating motor 15 , and the intermediate gear 16 is meshed and installed with the two rotating gears 14 .
[0023] In this structure, the middle gear is located between the two rotating gears and is meshed with the two rotating gears. When the rotating shaft needs to rotate, the rotating motor works and drives the middle gear to rotate. Under the linkage of the middle gear, the two rotating gears rotate at the same time, thereby driving the rotating shaft to rotate.
[0024] It is particularly important that the thickness of the rotating gear is half of the thickness of the intermediate gear. When the lifting cylinder drives the guide plate to move up and down a short distance, the two rotating gears will move up and down with it. The thickness of the intermediate gear is thicker than the two rotating gears, so that during the up and down movement of the rotating gear, the intermediate gear remains in meshing with the other two gears.
[0025] Finally, the machine platform 1 is provided with a notch 17, through which the top shaft 11 passes. The notch serves as a relief.
[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
