[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0018] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0019] Furthermore, the terms “inner end”, “outer end”, “vertical”, etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the location of the indicated technical features.

[0020] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", "set" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1-2 As shown, the thrust bearing grinding device of the electric screw press comprises a base 1, a grinding screw 2 is vertically provided at the center of the base 1, a thrust bearing 3 to be ground is sleeved on the grinding screw 2, a grinding paste 4 is provided between the thrust bearing 3 and the grinding screw 2 during grinding, a rotary bearing 5 is provided at the upper end of the base 1, an inner ring 501 of the rotary bearing 5 is fixed on the base 1, a gear 6 is provided on the side wall of the outer ring 502 of the rotary bearing 5, a servo motor 7 is provided on the base 1, the servo motor 7 is connected to a driving gear 8, the driving gear 8 is meshed with the gear 6 on the outer ring 502, a plurality of shifting plates 9 are provided at intervals along the circumferential direction at the upper end of the outer ring 502, the shifting plates 9 are connected to the thrust bearing 3 through a shifting rod 10, the servo motor 7 drives the outer ring 502 to rotate through the driving gear 8, and the outer ring 502 drives the thrust bearing 3 to rotate and grind through the shifting plates 9 and the shifting rod 10. By designing a slewing bearing 5, and by designing gear teeth 6 and a shift plate 9 on the slewing bearing 5, and designing a shift lever 10 on the shift plate 9, it is possible to utilize a servo motor 7 and a gear transmission to drive the outer ring 502 to rotate, and then the outer ring 502 drives the thrust bearing 3 to rotate through the shift plate 9 and the shift lever 10, thereby satisfying the action required for grinding. The overall structure is simple, practical, and low-cost, and automated grinding is achieved.

[0022] The lever 10 is sleeved with a spring 11, which is located between the lever plate 9 and the thrust bearing 3, and the spring 11 continuously presses the thrust bearing 3.
