Because new energy vehicles have higher requirements for the structural strength and mechanical properties of motors than traditional motors, especially the shell part of the motor, which needs to be treated with higher standards.

[0003] The most common strengthening treatment means for motor shells at present is shot blasting. In existing shot blasting equipment, such as the shot blasting machine for new energy motor shell machining disclosed in patent CN217668813U, the motor shell is placed on the conveying device when in use. When the motor shell moves under the shot blasting device, the conveying device stops moving, the limiting mechanism on both sides positions the motor shell, and then the shot blasting device performs shot blasting treatment on the motor shell. However, this method has at least two defects:

[0004] 1. The motor shell is placed on the conveying device, and the shot blasting device is arranged above the conveying device. No matter how the motor shell is placed, the side facing down cannot be treated by shot blasting, and the interior of the shell cannot be treated well either.

[0030] As shown in the figure, Figure 3 The positioning mechanism 6 comprises a positioning ring 61, an extension rod 62, an adjusting rod 63 and a driving assembly 64. The driving assembly 64 is fixedly arranged inside the shot blasting chamber 1 and is located above the waste recovery chamber 5. The positioning ring 61 is supported and arranged above the driving assembly 64 through the extension rod 62 and the adjusting rod 63. The extension rod 62 is arranged at both sides of the bottom of the positioning ring 61 in a radially symmetrical manner. The adjusting rod 63 is arranged at the other two sides of the bottom of the positioning ring 61 in a radially symmetrical manner and is spaced apart from the extension rod 62 by 90°.

[0031] As shown in the figure, Figure 4 A plurality of positioning grooves 611 are arranged on the positioning ring 61 in a circumferential manner and are equidistantly spaced. Before the shot blasting treatment, the motor shell 7 is placed on the positioning ring 61 in the axial direction. The bottom is connected with the flange plate at the end of the motor shell 7 through the positioning grooves 611 by using bolts, so as to temporarily fix the motor shell 7 on the positioning ring 61, thereby facilitating the shot blasting treatment.

[0032] According to the different diameters of the motor shell 7, the positions of the adjusting bolts in the positioning grooves 611 can be adjusted to adapt to motor shells 7 of different sizes.

[0033] As shown in the figure, Figure 5 The adjusting rod 63 comprises a rotating rod 631, a threaded rod 632 and a handle sleeve 633. The top of the rotating rod 631 is rotationally connected with the bottom of the positioning ring 61. The handle sleeve 633 is arranged at the bottom of the rotating rod 631. The bottom of the threaded rod 632 is fixedly connected with the driving assembly 64. The top is screwedly connected with the inside of the handle sleeve 633.

[0034] Rotating the handle sleeves 633 at both sides simultaneously drives the rotating rod 631 to rotate. Under the action of threads, the handle sleeve 633 can ascend and descend along the threaded rod 632, thereby driving the positioning ring 61 to ascend and descend, so as to adjust the height of the motor shell 7, adapt to motor shells 7 of different heights, and make the motor shell 7 at a suitable shot blasting height.

[0035] The telescopic rod 62 can be a spring rod, a hydraulic rod or an air spring, etc.

[0036] As shown in Figure 6 The driving assembly 64 comprises a housing 641, a support column 642, a driving motor 643, a gear 644, a toothed disc 645 and a rotating disc 646, the support column 642 is longitudinally arranged inside the housing 641, the toothed disc 645 is rotationally arranged on the top of the support column 642, the driving motor 643 is arranged on one side of the support column 642 and is in transmission connection with the toothed disc 645 through the gear 644, the rotating disc 646 is coaxially arranged above the toothed disc 645, and a thrust bearing 647 is arranged between the bottom of the rotating disc 646 and the top of the housing 641, so as to rotationally support the rotating disc 646.

[0037] As shown in Figure 7 The rotating disc 646 and the housing 641 are provided with a rotating step portion at the position outside the thrust bearing 647, an oil injection channel 648 is arranged above the rotating step portion, a sealing bolt 649 is arranged on the upper end of the oil injection channel 648, and the lower end outlet is in communication with the rotating friction surface of the rotating step portion.

[0038] The rotating step portion can seal the rotating connection position of the housing 641 and the rotating disc 646, so as to prevent the shot blasting dust from entering the inside of the housing 641, and the oil injection channel 648 can inject lubricating oil to the rotating connection position, so as to lubricate the rotating connection position and the thrust bearing 647 inside.

[0039] During the shot blasting process, the driving motor 643 drives the rotating disc 646 to rotate through the gear 644 and the toothed disc 645, and then drives the positioning ring 61 and the motor housing 7 above to rotate, so that the motor housing 7 rotates and performs shot blasting at the same time; since the shot is shot from the obliquely upper side, part of the shot can perform shot blasting on the outer wall of the motor housing 7, and part of the shot can enter the inside of the motor housing 7 to perform shot blasting on the inner wall, so that each position of the motor housing 7 can be fully shot blasted, and the shot blasting efficiency of the product is improved.
