Description

Technical Field

[0001] The utility model relates to the field of rotor-stator processing equipment, in particular to rotor-stator processing equipment with positioning and clamping functions. Background Art

[0002] The stator is an important component in a motor or generator and is usually fixed in the casing. In the motor, the stator interacts with the rotor through the magnetic field generated by the current, thereby causing the rotor to rotate. This rotation is the basis for the motor to generate power.

[0003] The stator-rotor processing equipment is equipped with various processing tools, such as milling heads, turning tools, grinding stones, etc., in order to perform different types of processing operations on the stator. In order to ensure the stability and accuracy of the stator during the processing, the stator-rotor processing equipment is usually equipped with a clamping device to firmly clamp the stator in the appropriate position.

[0004] However, the positioning clamping basically adopts a two-end clamping structure. Such a clamping structure cannot provide sufficient stability, resulting in slight movement or vibration of the stator during processing, affecting the processing accuracy and surface quality. In addition, clamping the stator with force may cause damage to the stator surface, such as scratches or deformation, which may affect the performance and life of the stator. Utility Model Content

[0024] See also Figure 4In this embodiment, there are two groups of clamping assemblies 6 and they are symmetrically distributed on the left and right. The clamping assembly 6 includes a support frame 601, a drive motor 602, a base 603, a spring sleeve group 604, a clamping bar 605, an extension frame 606, a first pneumatic clamping group 607, a second pneumatic clamping group 608 and a protective pad 609; a drive motor 602 for controlling the rotation of the rotor and stator is installed on the side of the support frame 601 away from the linear drive structure 2; the worker inserts the rotor and stator into the clamping assembly 6 at the right end, and multiple spring sleeve groups 604 and clamping bars 605 on the inner side of the base 603 perform preliminary positioning and clamping on the rotor and stator, and a base 603 is provided on the side of the output shaft of the drive motor 602 close to the linear drive structure 2; a ring-shaped equidistantly distributed spring sleeve group 604 is installed on the inner side of the base 603; a clamping bar 60 is fixedly connected to the inner side of the spring sleeve group 604 5; then the first pneumatic clamping group 607 and the second pneumatic clamping group 608 of the extension frame 606 perform staggered clamping on the rotor stator, so that the clamping force presents a symmetrical distribution on the stator surface, evenly distributes the clamping force, improves processing stability, and can also be applied to stators of various shapes, thereby improving the versatility and flexibility of clamping. The support frame 601 is fixedly connected with the extension frame 606 on one side close to the linear drive structure 2; the first pneumatic clamping group 607 symmetrically distributed vertically and the second pneumatic clamping group 608 symmetrically distributed laterally are respectively installed on the inner side of the extension frame 606; the clamping ends of the first pneumatic clamping group 607 and the second pneumatic clamping group 608 are both provided with protective pads 609; the first pneumatic clamping group 607 and the second pneumatic clamping group 608 are staggered; the protective pads 609 at the clamping ends can protect the stator surface to avoid damage during clamping.

[0025] When working, the first step is to place the processing table 1 on a flat surface and firmly fix it to the flat surface using the fixing ears 7 on both sides to ensure that the processing table 1 will not move during the processing of the stator, thereby improving the stability of the equipment.
