[0002] The air conditioner motor is one of the most important components of the air conditioner, and mainly includes a compressor, a fan motor (axial flow fan and cross flow fan), and swinging air supply blades (stepping motor and synchronous motor). During production of the air conditioner motor shaft, a shaft blank is processed by turning on a lathe. During transportation or storage, the shaft blank may be bent due to stress. When the shaft blank with the bending degree is turned, the cutting depth of the bent part is different, and a large area needs to be processed during turning, which increases the difficulty of programming of the machine tool.

[0003] A straightening mechanism for air conditioner motor shaft production is disclosed in the Chinese patent document with the application number 202321030728.X, which includes a power mechanism, a force applying mechanism, and a straightening die. A through hole for straightening is provided in the middle of the straightening die. The shaft blank is driven to move horizontally inside the center through hole of the straightening die by the power mechanism and the force applying mechanism, and the shaft blank is straightened. However, the center through hole of the straightening die is in sliding friction with the shaft blank, which may cause wear of the shaft blank during straightening. At the same time, the center through hole has a fixed size, and can only straighten shaft blanks of a specific size. When shaft blanks of different sizes need to be straightened, the straightening die needs to be replaced, which is troublesome. SUMMARY

[0019] Please see Figures 1-4This utility model provides an embodiment of a shaft processing equipment for producing air conditioner motor shafts, including a base 1, a support plate 2 vertically mounted on the top of the base 1, and a pushing mechanism 6 for pushing the air conditioner motor shaft to move horizontally. A through hole 201 is provided through the center of the support plate 2 to accommodate the horizontal movement of the air conditioner motor shaft. The pushing mechanism 6 includes a push plate 601 vertically mounted on one side of the support plate 2 and a second linear drive member 602 that drives the push plate 601 to move back and forth towards or away from the support plate 2. In this embodiment, the second linear drive member 602 is a lead screw motor mounted on the bottom of the base 1. A slider threadedly connected to the lead screw is fixed to the bottom of the push plate 601, and a strip-shaped sliding hole is provided through the top of the base 1 to accommodate the horizontal movement of the push plate 601. Further, the second linear drive member 602 can also be configured as a cylinder or hydraulic cylinder, etc., as needed.

[0020] Furthermore, a push rod 603 is fixed on the side of the push plate 601 near the support plate 2, and the central axis of the push rod 603 coincides with the axis of the through hole 201. The push rod 603 abuts against one end of the motor shaft, which can completely push the motor shaft out of the through hole 201.

[0021] Several rollers 4 are mounted on the side of the support plate 2 near the pushing mechanism 6 via mounting brackets 3. See the attached document for details. Figure 4 The mounting bracket 3 has an L-shaped structure. In this embodiment, there are four rollers 4, but other numbers can be set as needed. The rollers 4 are rolled to the outer wall of the air conditioner motor shaft. When the drive motor shaft passes between the four rollers 4, it can be straightened. At the same time, the rollers 4 and the motor shaft have rolling friction, which can reduce wear.

[0022] Several rollers 4 are arranged in a circular array around the center of the through hole 201. An adjustment mechanism 5 is provided on the support plate 2 to drive several mounting brackets 3 to move synchronously along the radial direction of the through hole 201. The adjustment mechanism 5 includes a drive ring 501 coaxially rotatably mounted on one side of the support plate 2 with the through hole 201, four arc-shaped sliding holes 502 penetrating the drive ring 501, four limiting sliding holes 503 penetrating the support plate 2, connecting pieces 504 slidably disposed inside the arc-shaped sliding holes 502 and the limiting sliding holes 503, and a drive module that drives the drive ring 501 to rotate. The inner diameter of the drive ring 501 is equal to the inner diameter of the through hole 201, and the arc length of the arc-shaped sliding holes 502 rotates radially along the drive ring 501. Externally, a limiting sliding hole 503 is radially arranged on the support plate 2 along the through hole 201, and the limiting sliding hole 503, the arc-shaped sliding hole 502, the connector 504 and the mounting bracket 3 correspond one-to-one. The connector 504 passes through the limiting sliding hole 503 and the arc-shaped sliding hole 502 in sequence and is fixedly connected to the mounting bracket 3. The connector 504 is slidably connected to the arc-shaped sliding hole 502 and the limiting sliding hole 503. When the drive ring 501 rotates, it drives the connector 504 to rotate inside the arc-shaped sliding hole 502, which in turn drives the connector 504 to slide in a straight line inside the limiting sliding hole 503. Then, the distance between each mounting bracket 3 and the center of the through hole 201 is adjusted synchronously, which can straighten motor shafts of different sizes.

[0023] In this embodiment, the drive module includes an outer gear ring 505 fixed on the outer circumference of the drive ring 501 and a rack 506 linearly slidably arranged via a first linear drive member 507. The outer gear ring 505 and the rack 506 mesh with each other. The first linear drive member 507 can be an electric push rod, hydraulic cylinder, etc., horizontally installed on one side of the base 1. The first linear drive member 507 is located below the rack 506. The output end of the first linear drive member 507 is fixedly connected to one end of the rack 506. The rack 506 moves horizontally by the extension and retraction of the first linear drive member 507, which in turn drives the outer gear ring 505 and the drive ring 501 to rotate.

[0024] In this embodiment, the connector 504 is a bolt. The mounting bracket 3 has a through hole to accommodate the connector 504. The connector 504 passes through the limiting sliding hole 503, the arc-shaped sliding hole 502 and the through hole on the mounting bracket 3 in sequence, and is then threadedly connected to a fastening nut 508. When the position of the roller 4 needs to be adjusted, the fastening nut 508 is loosened. After the adjustment is completed, the fastening nut 508 is tightened to fix the position of the mounting bracket 3, thereby improving the stability of the mounting bracket 3 and the roller 4.

[0025] Working principle: Insert one end of the air conditioner motor shaft to be straightened between each roller 4. The first linear drive 507 pushes the rack 506 to slide horizontally, which in turn drives the drive ring 501 to rotate. The connecting piece 504 rotates inside the arc-shaped sliding hole 502 towards the center of the through hole 201. Under the limit of the limiting sliding hole 503, the connecting piece 504 and the mounting bracket 3 move towards the center of the through hole 201 until each roller 4 abuts against the outer circumference of the motor shaft. Then, the second linear drive 602 drives the push plate 601 to move horizontally towards the side of the support plate 2. The push rod 603 abuts against one end of the motor shaft, pushing the motor shaft through each roller 4 for straightening.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
