[0003] According to a clamping device for machining a motor drive shaft mentioned in the utility model patent with the Chinese patent application number 202321991552.4, when the clamping device for machining the motor drive shaft is in use, it can ensure that the motor drive shaft to be machined can be mutually adapted to the clamping groove and is clamped and fixed through the clamping device. However, when the clamping device for machining the motor drive shaft is in use, it does not have the function of rotating the drive shaft during the clamping process. When grinding or other machining operations are performed on the outer surface of the drive shaft, the fixed clamping device can only clamp one side, and the drive shaft needs to be taken and placed multiple times for machining, resulting in a reduction in the machining efficiency of the drive shaft. Therefore, it is necessary to propose a processing device for a drive shaft of an automotive air conditioner compressor to solve the above-mentioned problems. Summary of the Utility Model

Specific implementation manners

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , a driving shaft processing device for an automotive air conditioner in this embodiment, includes a processing table 1, a translation structure 2 is movably installed inside the processing table 1, two groups of translation plates 3 are movably installed on the top of the processing table 1, fixed discs 4 are fixedly installed on the tops of the two groups of translation plates 3, a rotating assembly 8 is movably installed inside the fixed disc 4, and a clamping assembly 6 is movably installed at the right side surface of the fixed disc 4;

[0021] The rotating assembly 8 includes a driving motor 801, the driving motor 801 is fixedly installed at the left side surface of the translation plate 3, a gear 802 is fixedly connected to the output shaft of the driving motor 801, an external gear ring 805 is meshed with the outer surface of the gear 802, and a turntable 803 is fixedly installed inside the external gear ring 805.

[0022] In the case implementation, one end of the driving shaft is placed at the middle position among the four clamping plates 603, and by starting the micro electric rod 602, the output shaft of the micro electric rod 602 will drive the clamping plate 603 to approach the outer surface of the driving shaft, and the four clamping plates 603 will clamp and fix one end of the driving shaft. Through the setting of the rubber pad 604, the friction between the rubber pad 604 and the driving shaft can be increased to avoid slipping.

[0023] In the case implementation, the translation structure 2 drives the two translation plates 3 to gradually approach, so as to adjust the distance between the two groups of fixed discs 4 according to the length of the drive shaft, which is convenient for fixing both ends of the drive shaft and ensures better stability during the later processing of the drive shaft. Start the drive motor 201, and the output shaft of the drive motor 201 drives the threaded rotating rod 202 to rotate. Due to the limiting effect of the chute 7, the threaded rotating rod 202 will drive the first threaded block 203 and the second threaded block 204 to approach the middle or move to both sides synchronously, so as to adjust the distance between the two fixed discs 4 according to the drive shafts of different lengths.

[0024] In the case implementation, when the two ends of the drive shaft are clamped and fixed by the clamping assembly 6 and the translation structure 2 in cooperation, start the drive motor 801. The output shaft of the drive motor 801 will drive the gear 802 to mesh with the external gear ring 805, so as to drive the turntable 803 and the clamping assembly 6 to rotate synchronously. At this time, the rotating assemblies 8 on the left and right sides rotate in opposite directions, causing the drive shaft to rotate in the same direction synchronously, which is convenient for continuous processing operations of the drive shaft and improves the processing efficiency of the drive shaft.

[0025] During implementation, the operations are carried out in the following steps:

[0026] 1) First, place one end of the drive shaft in the middle position of the four clamping plates 603;

[0027] 2) Then, clamp and fix one end of the drive shaft through the clamping assembly 6;

[0028] 3) Then, drive the two fixed discs 4 to gradually approach through the translation structure 2, and fix the other end of the drive shaft again through the clamping assembly 6;

[0029] 4) Finally, drive the drive shaft to rotate slowly through the rotating assembly 8.

[0030] To sum up, for the drive shaft processing device of the automotive air conditioner compressor, by setting the clamping assembly 6, during use, place one end of the drive shaft at the middle position of the four clamping plates 603, and start the micro electric rod 602. The output shaft of the micro electric rod 602 will drive the clamping plate 603 to approach the outer surface of the drive shaft, and the four clamping plates 603 will clamp and fix one end of the drive shaft. Then, drive the two translation plates 3 to gradually approach through the translation structure 2, so as to be able to adjust the distance between the two groups of fixed discs 4 according to the length of the drive shaft, which is convenient for fixing both ends of the drive shaft and ensures better stability during the later processing of the drive shaft.

[0031] Moreover, by setting the rotating assembly 8, during use, when the clamping assembly 6 and the translation structure 2 cooperate to clamp and fix both ends of the drive shaft for machining, by starting the drive motor 801, the output shaft of the drive motor 801 will drive the gear 802 to mesh with the external gear ring 805, so as to drive the turntable 803 and the clamping assembly 6 to rotate synchronously. At this time, the rotating assemblies 8 on both the left and right sides rotate in opposite directions, causing the drive shaft to rotate synchronously in one direction, facilitating continuous machining operations on the drive shaft and improving the machining efficiency of the drive shaft.
