Description

Technical Field

[0001] This utility model relates to the field of stepper motor technology, and specifically to a stepper motor equipped with a guiding mechanism. Background Technology

[0002] A stepper motor consists of a stator (electromagnetic poles) and a rotor (permanent magnets). When the stator windings are energized sequentially, the magnetization direction of the electromagnetic poles changes, attracting or repelling the rotor, causing it to rotate gradually. It is widely used in automated control systems. Its core feature is that the motor is driven to rotate by a controller sending pulse signals, with each pulse corresponding to a fixed step angle (such as 1.8° or less), thus achieving precise positioning.

[0003] However, existing stepper motors cannot effectively limit the position of their output shaft during use, thus failing to provide effective guidance. This can easily cause the output shaft to deviate during operation, resulting in ineffective output rotation and reduced output and rotation efficiency. Furthermore, the guide position cannot be effectively adjusted, preventing the output shaft from being limited and guided to different positions according to actual needs, thereby reducing its limiting and guiding efficiency and overall efficiency. Therefore, we propose a stepper motor with a guiding mechanism. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application proposes a stepper motor equipped with a guiding mechanism, which effectively limits the position of its output shaft, thereby enabling effective guidance and preventing the output shaft from deviating during the process. This, in turn, allows for efficient output rotation, improving both output and rotation efficiency.

[0008] As a preferred embodiment of this utility model, the connecting post is fitted with a buffer spring, and the two ends of the buffer spring are respectively connected to the first tube and the second tube.

[0009] As a preferred embodiment of this utility model, the output shaft is fitted with a disc component, and the disc component has a plurality of evenly distributed mating holes.

[0010] As a preferred embodiment of this utility model, the left side of the annular plate is connected to several evenly distributed movable columns, and the movable columns are fitted with a circular tube, the left end of which is connected to the right side of the main body.

[0015] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0016] like Figures 1 to 7 As shown, a stepper motor with a guiding mechanism includes: a main body 1, an output shaft 16 connected to the right side of the main body 1, an annular plate 9 sleeved near the left side of the output shaft 16, the left side of the annular plate 9 being movably connected to the right side of the main body 1, a plurality of annular limiting grooves 21 being opened on the right side of the annular plate 9, a plurality of evenly distributed rolling balls 25 being sleeved in the annular limiting grooves 21, and a first tube 7 being movably connected to the right side of the rolling balls 25, a docking post 11 being sleeved on the right side of the first tube 7, and a second tube 10 being sleeved on the right side of the docking post 11. In this embodiment, a fixing block 12 is sleeved on the second tube body 10, and a column 19 is connected to the other side of the fixing block 12. A nut 24 is sleeved on the output shaft 16, and an external thread 13 matching the nut 24 is opened on the outer wall of the output shaft 16. Several evenly distributed platform blocks 20 are connected to the outer wall of the nut 24. A circular groove 26 matching the column 19 is opened on the platform block 20 and the column 19 respectively. A threaded hole 18 is opened on the platform block 20 and the column 19. A fastening screw 17 is sleeved in the threaded hole 18, so that it can effectively limit the position of the output shaft 16, thereby enabling it to be effectively guided and preventing the output shaft from deviating during the process. This allows it to effectively output rotation, improving its output efficiency and rotation efficiency. Example 2

[0017] like Figures 1 to 7As shown, the top of the annular plate 9 is connected to a fixing plate 6 by bolts. The top of the main body 1 is close to the bonding block 5, and the side wall of the bonding block 5 is provided with a screw hole. A T-shaped screw 4 is fitted inside the screw hole. The right end of the T-shaped screw 4 is movably connected to the left side wall of the fixing plate 6 by a bearing. A buffer spring 8 is fitted on the outer sleeve of the docking column 11. The two ends of the buffer spring 8 are respectively connected to the first tube 7 and the second tube 10. A disc part 14 is fitted on the outer sleeve of the output shaft 16. Several evenly distributed docking holes 15 are provided on the disc part 14. Implementation plan: Several evenly distributed movable columns 22 are connected to the left side of the annular plate 9. The movable columns 22 are covered with a circular tube 23. The left end of the circular tube 23 is connected to the right side of the main body 1. The bottom of the main body 1 is connected to a pad 3 by bolts. The top of the pad 3 is provided with stabilizing holes 2 near the four corners, so that its guiding position can be effectively adjusted. This allows the output shaft to be limited and guided at different positions according to actual needs, improving its limiting and guiding efficiency and usage efficiency. Working Principle: In use, this technical solution first removes the fastening screw 17, allowing the column 19 to slide in the circular groove 26. The distance between the two sets of rolling balls 25 is adjusted so that they correspond sequentially to several annular limiting grooves 21. The fastening screw 17 is then tightened to fix the column, effectively limiting the position of the output shaft 16 and guiding it effectively. This prevents the output shaft from shifting during operation, ensuring efficient output rotation and improving output and rotation efficiency. Rotating the nut 24 clockwise or counterclockwise moves it left and right on the output shaft 16 via the external thread 13, adjusting its left and right position. Rotating the T-shaped screw 4 clockwise or counterclockwise moves the annular plate 9 and the annular limiting grooves 21 to the right or left via the fixing piece 6, adjusting the contact and distance between the annular limiting grooves 21 and the rolling balls 25. This effectively adjusts the guiding position, allowing for limiting and guiding the output shaft to different positions as needed, improving limiting and guiding efficiency and overall usage efficiency.
