The support base 100 may extend in a vertical direction, and the vertical moving assembly 200 may be disposed at an upper end of the support base 100 to reserve a sufficient space for guiding the gear plate. The vertical moving assembly 200 is used to drive the fixing plate 300 to move in the vertical direction, and correspondingly drives the cover die 400 to move in the vertical direction.

Both sides of the cover die 400 are provided with a pilot groove 410 for inserting the lug on the gear plate, and the extending direction of the pilot groove 410 is the same as that of the lug on the gear plate, and both can extend along the vertical direction. The guide groove 410 includes a guide portion 411 and a guide portion 412, and the guide portion 412 is connected to the guide portion 411 and is located below the guide portion 411. The width of the guide portion 412 is gradually increased in a direction extending downward to guide the lug to the guide portion 411 through the sidewall of the guide portion 412.

The motor to be aligned may be located below the cover die 400, and the vertical moving assembly 200 drives the cover die 400 to move downward, so that the cover die 400 gradually approaches the motor to be aligned and finally the lugs on the gear plate are inserted into the guide portions 412 (since the gear plate is usually slightly deviated, the lugs may be inserted into the guide portions 412). If the gear plate in the motor housing is misaligned, the lug moves along the inner wall of the guide part 412 to the guide part 411, which generates a lateral driving force to the gear plate, so that the gear plate rotates to a correct position. The position of the guiding part 411 relative to the cover die 400 is preset, and after the lug on the gear plate is inserted into the guiding part 411, the gear plate moves to the correct position from the deflection position relative to the motor shell, so that the guiding of the gear plate is completed, and the subsequent processing process of the motor can be smoothly carried out.

In some embodiments, the outer circumferential surface of the die sleeve 400 is circular, and the pilot groove 410 is disposed on the outer circumferential surface of the die sleeve 400 and extends to the bottom surface of the die sleeve 400.

Since the width of the guide portion 411 is very close to that of the lug, the lug is easily caught by the guide portion 411 after the gear plate is straightened, so that the cover die 400 cannot be separated from the gear plate. For this, in this embodiment, an air blowing passage is provided in the cover mold 400, the air blowing passage forms an air inlet at a side surface of the cover mold 400, the air blowing passage forms an air outlet 421 at a bottom surface of the cover mold 400, and the air inlet is used for connecting with an air compressor. After finishing the alignment of the gear plate, the air compressor can be turned on to generate high pressure air, and the air outlet 421 blows air outwards to blow the gear plate off the cover die 400, so as to avoid material jamming.

In this embodiment, in order to facilitate connection of the air pipe, the connector 422 may be fixed at the air inlet of the cover die 400, and the external pipeline may be directly connected to the connector 422.

In some embodiments, the vertical moving assembly 200 includes a first vertical moving assembly and a second vertical moving assembly, the first vertical moving assembly is disposed on the support base 100 and connected to the second vertical moving assembly, and the fixing plate 300 is connected to the second vertical moving assembly. The first vertical moving assembly is used for driving the second vertical moving assembly to move along the vertical direction, and correspondingly driving the fixing plate 300 to move along the vertical direction; the second vertical moving assembly is used to drive the fixing plate 300 to move in the vertical direction.

When guiding the gear plate, the first vertical moving assembly drives the second vertical moving assembly to move towards the motor to be guided, so that the sleeve die 400 is close to the motor to be guided, and then the second vertical moving assembly drives the sleeve die 400 to guide the gear plate, and a two-stage driving mode is formed. The significance of such an arrangement is that a second vertically moving component with a relatively weak driving force can be provided, avoiding damage to the gear plate by applying an excessive driving force to the cover die 400.

The second vertical moving assembly is disposed on the fixed seat 213, the first driver 214 drives the fixed seat 213 to move along the vertical direction, and the sliding fit between the vertical slider 212 and the vertical guide rail 211 can keep the fixed seat 213 moving along the vertical direction.

In this embodiment, the supporting seat 100 may be fixed with a supporting plate 110 vertically disposed thereon, the supporting plate 110 has a wider width, and two vertical guide rails 211 may be fixed on the supporting plate 110, and correspondingly, two vertical guide rails 211 are both provided with one vertical slider 212, and the two vertical sliders 212 are both connected to the fixing seat 213, so as to promote the guiding function.

During the process that the second driver 221 drives the fixing plate 300 to move, the guide rod 222 moves relative to the fixing plate 300, thereby playing a guiding role to keep the fixing plate 300 moving in the vertical direction. The second driver 221 may also be an air cylinder, a push rod of the air cylinder is connected to the fixing plate 300, and the fixing plate 300 is driven to move in the vertical direction by the extension and contraction of the push rod.

Further, a pressing rod 223 vertically penetrating through the fixing plate 300 and the cover die 400 is fixed on the fixing seat 213, and the pressing rod 223 can move in the vertical direction relative to the fixing plate 300 and the cover die 400. When the gear plate is guided, the first vertical moving assembly drives the fixing seat 213 to move downwards, and when the lower end of the pressing rod 223 abuts against the gear plate, the first vertical moving assembly stops. After that, the second vertical moving assembly drives the cover die 400 to guide the gear plate, and the gear plate does not shake in the vertical direction due to the pressing rod 223 abutting on the gear plate, so as to move from the deflection position to the correct position more smoothly.
