The auxiliary component 14 includes a top plate 1401 and a built-in stud 1402, and the internal thread of the top plate 1401 is installed with the built-in stud 1402. During operation, the built-in stud 1402 can be rotated clockwise or counterclockwise, which is conducive to adjusting the extension distance of the built-in stud 1402 with respect to the top plate 1401, and is convenient for adaptive adjustment according to the size and habits of the motor and encoder. The user fits the center of the encoder or motor to the end area of ​​the built-in stud 1402, which is conducive to determining that the encoder or motor is in the center when fixed.

[0023] If Figure 2 ​As shown in the figure, side plates 12 are arranged on both sides of the extension plate 9. A fixing component 15 for fixing articles is arranged between the two groups of side plates 12. The fixing component 15 includes a second lead screw 1501, a threaded sleeve 1502, a fixing plate 1503 and a rubber pad 1504. There are two groups of fixing components 15, and the structures of the two groups of fixing components 15 are exactly the same. Threaded sleeves 1502 are threadedly installed on both sides of the outer surface of the second lead screw 1501, and a fixing plate 1503 is arranged at the bottom of the threaded sleeve 1502. A rubber pad 1504 is installed on the outer surface of the fixing plate 1503.

By rotating the first lead screw 11, the two auxiliary plates 6 can be made to approach the center of the base 1. The two auxiliary plates 6 are parallel to each other. Therefore, during the relative movement, the auxiliary plate 6 can rotationally adjust the extension plate 9 with an angular offset with the base 3 as the center, so that the two extension plates 9 coincide, which is beneficial for angle calibration of the fixed encoder and motor, making the above two concentric, providing convenience for subsequent connection and assembly.

[0025] In summary, for the center tooling of the brake-mounted resolver encoder that is convenient for calibration, first, according to Figures 1 - 3The structure shown in [description] can be rotated clockwise or counterclockwise during operation to rotate the built-in stud 1402, which is beneficial to adjusting the elongation distance of the built-in stud 1402 with respect to the top plate 1401, facilitating adaptive adjustment according to the sizes and characteristics of the motor and the encoder. The user fits the center of the encoder or the motor to the end region of the built-in stud 1402, which is beneficial to determining that the encoder or the motor is in the central position when fixed. Then, there are two sets of threaded sleeves 1502. The internal thread directions of the two sets of threaded sleeves 1502 are opposite, and the distances between the two sets of threaded sleeves 1502 with respect to the built-in stud 1402 are the same. By rotating the second lead screw 1501, the two fixed plates 1503 and rubber pads 1504 connected to the threaded sleeves 1502 can be synchronously driven to move towards the center of the built-in stud 1402, facilitating synchronous fixation from both sides of the encoder or the motor, which is beneficial to keeping the centers of the encoder or the motor consistent. Additionally, the design of the two hydraulic rods 4 facilitates the fitting of the encoder and the motor shaft after fixation, making the centers aligned, which is beneficial for the operator to perform assembly connection. Then, the bottom thread directions of the two auxiliary plates 6 are opposite, and the distances between the two auxiliary plates 6 with respect to the horizontal center line of the base 1 are the same. By rotating the first lead screw 11, the two auxiliary plates 6 can be made to approach the center of the base 1. The two auxiliary plates 6 are parallel to each other. Thus, during the relative movement, the auxiliary plates 6 will adjust the angularly offset extension plates 9 in a rotational manner with the base 3 as the center, making the two extension plates 9 coincide, which is beneficial for angle calibration of the fixed encoder and motor, making the above two concentric, providing convenience for subsequent connection and assembly. Additionally, when the center tooling does not need to be used, the design of engaging the connecting plate 8 with the auxiliary plate 6 can be used to store and protect the internal parts from both sides of the base 1.
