TECHNICAL FIELD
[0001] The utility model relates to a step motor technical field, concretely is a step motor with good shock absorption performance. BACKGROUND
[0002] A step motor is a kind of motor that converts electrical pulse signals into mechanical angular displacement, and the angular displacement of its rotor is proportional to the number of input pulses, and the rotational speed is proportional to the pulse frequency. Step motors are widely used in applications that require precise control of position and speed, such as industrial automation, robotics, medical devices, office automation, and other fields.
[0003] A step motor is an actuator that is controlled by electrical pulses and converts electrical pulses into angular displacement. It can rotate at precise step angles without the need for feedback to the control system. This is because the rotation inside the step motor is in a discrete step-by-step manner, with each step equivalent to a fixed angle. However, the step motor generates vibrations during operation, which can affect the performance of certain applications. These vibrations can cause wear and tear on mechanical components, reducing the accuracy of the system.

The movable connection structure is installed on one side of the first shock absorption structure. The bottom of the bearing seat is provided with two groups of connecting blocks.
[0005] The step motor with good shock absorption performance described above uses shock absorption structure at the bottom of the step motor for shock absorption, but the shock absorption performance is poor. The step motor itself generates vibrations during operation, and the rotor mechanical components of the step motor itself still have wear and tear, resulting in reduced system accuracy.

However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example
[0030] Please see Figures 1-6 This utility model provides a technical solution: a stepper motor with good shock absorption performance, including a stepper motor 1 and a shock absorption component 2. The stepper motor 1 includes a body 11, an output shaft 12 is installed on the front side of the body 11, the shock absorption component 2 is located outside the output shaft 12 on the front side of the body 11, a plurality of first fixing screw holes 121 are provided on the front side of the body 11 near the outer edge outside the output shaft 12, and a shock absorption groove 122 is opened on the front side of the body 11 outside the output shaft 12.
[0031] It should be noted that in this embodiment, the application reduces the mechanical wear of the stepper motor 1 by setting a shock-absorbing component 2 outside the output end of the stepper motor 1, thereby extending the service life of the equipment and improving operating efficiency. The shock-absorbing component 2 is tightly connected to the body 11 through the fixing component 21 to ensure stable shock absorption. The meshing design of the shock-absorbing rings 22 and 23 effectively disperses vibration energy and further optimizes the shock absorption performance. The spring structure of the shock-absorbing component 24 provides elastic support and enhances the overall shock absorption effect. In addition, the through hole 212 of the shock-absorbing component 2 is designed to facilitate installation and maintenance, improving practicality;
[0032] Furthermore, the positions of the damping rings 22 and 23 can be adjusted according to actual needs to flexibly cope with different working conditions. The cooperation between the damping sliding plate 241 and the damping sliding groove 232 ensures that the damping component 24 operates stably during vibration, further reducing noise and improving user experience.
[0033] Please see Figure 2 , 34, 5, and 6, the shock absorption assembly 2 includes a fixing member 21, a first shock absorption ring 22, a second shock absorption ring 23, and a shock absorption component 24 located inside the first shock absorption ring 22. The fixing member 21 has a rectangular structure and matches the front structure of the body 11. The fixing member 21 has second fixing screw holes 211 corresponding to the first fixing screw holes 121 on its periphery near the outer edge. A through hole 212 for the output shaft 12 is opened in the center of the fixing member 21. The first shock absorption ring 22 has an annular structure and is located outside the second shock absorption ring 23. First shock absorption protrusions 221 are evenly arranged on the inner circumferential wall of the first shock absorption ring 22. Second shock absorption protrusions 222 are arranged between every four first shock absorption protrusions 221 on the inner circumferential wall of the first shock absorption ring 22. The second shock absorption ring 23 is located... Inside the first damping ring 22, damping engagement blocks 231 are evenly arranged on the outer circumferential wall of the second damping ring 23. Eight sets of damping sliding grooves 232 are evenly opened on the circumferential wall of the second damping ring 23. The damping component 24 is located inside the damping sliding groove 232. The damping engagement blocks 231 on the outer circumferential wall of the second damping ring 23 are sequentially limited and engaged with the first damping protrusions 221 on the inner circumferential wall of the first damping ring 22. The damping component 24 includes a damping sliding plate 241 and a damping spring 242. Each damping sliding plate 241 is installed inside the damping sliding groove 232 through the damping spring 242. The damping sliding plate 241 abuts against the second damping protrusions 222. When the first damping ring 22 is embedded in the through hole 212, the outer circumferential wall of the end of the first damping ring 22 is embedded in the damping groove 122.
[0034] It should be noted that in this embodiment, the fastener 21 is made of cold-rolled steel plate, which has high strength and wear resistance, ensuring the stability and durability of the overall structure. The thickness is 2.0 mm. The selection of cold-rolled steel plate not only improves the mechanical properties of the fastener 21, but also further optimizes the overall weight distribution of the shock absorption component 2 through precise thickness control, so that it maintains a lightweight design while achieving efficient shock absorption, greatly enhancing the portability and service life of the equipment.
[0035] The shock-absorbing sliding plate 241 is made of highly elastic material, effectively absorbing vibration energy, improving the shock absorption effect, and extending the service life of the equipment. The shock-absorbing spring 242 is made of high-quality stainless steel, which is highly corrosion-resistant and ensures long-term stable operation. The overall design is exquisite, and the various components work together to significantly improve the smoothness of equipment operation.
[0036] The first damping ring 22 and the second damping ring 23 are made of natural rubber, which has good elasticity and energy absorption properties. This effectively absorbs vibration and impact energy, reducing structural deformation and damage. It effectively reduces vibration during stepper motor operation, decreases wear on mechanical parts, and improves system stability and accuracy. Furthermore, the superior aging resistance of natural rubber ensures long-term durability of the damping effect. The overall design of the damping assembly 2 balances efficient damping with lightweight structure, significantly improving the overall performance of the equipment. It is suitable for various complex working conditions, extends equipment maintenance cycles, and reduces operating costs.
[0037] Furthermore, the first damping ring 22 is arranged in a ring structure and is located outside the second damping ring 23. First damping protrusions 221 are evenly arranged on its inner circumferential wall, and second damping protrusions 222 are arranged between every four first damping protrusions 221.

Eight sets of damping sliding grooves 232 are evenly formed on the circumferential wall. The damping component 24 includes a damping sliding plate 241 and a damping spring 242. Each damping sliding plate 241 is installed inside the damping sliding groove 232 via the damping spring 242. The second damping tooth 222 abuts against the output shaft 12, ensuring that when vibration occurs during equipment operation, the output shaft 12 will deviate and squeeze the damping sliding plate 241. The damping sliding plate 241 can respond flexibly to vibration and effectively disperse the impact force through the reaction force of the damping spring 242, thereby significantly reducing the wear of internal components and extending the service life of the overall equipment. The design of the damping sliding groove 232 further optimizes the damping effect. Its internal structure ensures that the damping sliding plate 241 can slide smoothly when subjected to impact, reducing friction, improving response speed, effectively reducing noise during equipment operation, and enhancing user experience.
[0038] Furthermore, the damping engagement block 231 on the outer circumferential wall of the second damping ring 23 and the first damping protrusion 221 on the inner circumferential wall of the first damping ring 22 are sequentially engaged and connected. This engagement ensures a stable connection between the second damping ring 23 and the first damping ring 22, preventing vibrations generated during motor operation from causing component loosening or displacement. This further enhances the stability and safety of the equipment. The precise fit between the damping engagement block 231 and the first damping protrusion 221 ensures high-precision operation even under complex working conditions, effectively extending the equipment maintenance cycle, reducing maintenance costs, and improving overall work efficiency. The optimized design of the vibration damping system not only improves the equipment's vibration resistance but also achieves efficient energy absorption and dispersion through a refined structural layout. This ensures that all components maintain excellent coordination and durability during long-term, high-intensity operation, thereby significantly improving the overall performance of the equipment and the user experience.
[0039] The fixing component 21 is fixed to the front side of the machine body 11 through the first fixing screw hole 121 and the second fixing screw hole 211. The first damping ring 22 is embedded in the through hole 212, and the outer circumferential wall of its end is embedded in the damping groove 122. The second damping ring 23 is connected to the first damping tooth 221 on the first damping ring 22 through the damping engagement block 231, which is sequentially limited and engaged. The damping component 24 is installed in the damping sliding groove 232 and provides a damping effect through the damping spring 242. When the stepper motor 1 is running, the vibration generated is reduced. The vibration energy is first transmitted to the first damping ring 22 and the second damping ring 23. Through the interaction of the damping teeth and the damping engagement block, the first damping ring 22 and the second damping ring 23 disperse and absorb part of the vibration energy. The damping spring 242 in the damping component 24 further absorbs the vibration energy, reducing the impact of vibration on the output shaft 12 and mechanical components. This ensures that the output shaft 12 remains stable during high-speed operation, reduces noise, improves operating accuracy, enhances the reliability and durability of the equipment, extends its service life, and improves overall work efficiency.
[0040] The second damping ring 23 is installed inside the first damping ring 22. The damping engagement block 231 engages with the first damping tooth 221, and the damping sliding plate 241 abuts against the second damping tooth 222. The first damping ring 22 is embedded inside the through hole 212 and sleeved on the outside of the output shaft 12, ensuring that the outer circumferential wall of the end of the first damping ring 22 is embedded in the damping groove 122. The fixing member 21 is fixed to the front side of the machine body 11 by bolts. After installation, it is ready for use. When the stepper motor is running, the vibration generated is first transmitted to the first damping ring 22 and the second damping ring 23. The first damping ring 22 and the second damping ring 23 disperse and absorb part of the vibration energy through the interaction of the damping tooth and the damping engagement block. The damping spring 242 in the damping member 24 further absorbs the vibration energy, reducing the impact of vibration on the output shaft 12 and mechanical components.
