[0017] like Figure 1 As shown, the servo motor gear rack positioning mechanism includes an annular guide rail 1, on which a servo motor 2, a gear 3, a rack 4, a linear slide rail slide 5, a positioning bearing 6 and a positioning plate 7 are arranged, and a positioning movable plate 8 is installed on the positioning bearing 6. The gear 3 is respectively connected to the servo motor 2 and the rack 4 in a transmission manner, and the rack 4 is connected to the linear slide rail slide 5 in a transmission manner. The positioning bearing 6 is installed on the linear slide rail slide 5, and a sliding through hole 9 for the positioning bearing 6 to pass through is opened on the positioning movable plate 8. It can be understood that the annular guide rail 1, the gear 3, the rack 4, the linear slide rail slide 5, the positioning bearing 6 and the positioning plate 7 can all be made of stainless steel or the like.

[0018] Specifically, the servo motor 2 is installed on one side of the annular guide 1, and the gear 3 is installed on the other side of the annular guide 1. The output shaft of the servo motor 2 passes through the annular guide 1 and is connected to the gear 3 in transmission. The rack 4 and the linear slide 5 are both located in the middle of the annular guide 1, and the gear 3 is meshed with the rack 4. A bearing mounting plate 10 is provided on the linear slide 5, and the positioning bearing 6 is installed on the bearing mounting plate 10. A plurality of sliders 11 are slidably installed on the annular guide 1, and the positioning plate 7 is installed on the slider 11. The sliding through hole 9 is tilted toward the lower right. It can be understood that the control mode of the servo motor is a bus or a pulse, and the positioning position accuracy is controlled by traveling a fixed distance or a fixed pulse amount. The limit sensor detects whether it is in place, thereby realizing the forward and reverse rotation of the servo motor and achieving the effect of precise round-trip positioning.
