Description

Technical Field

[0001] This utility model relates to the field of stepper motor manufacturing technology, specifically to a lightweight stepper motor end cover with a dustproof structure. Background Technology

[0002] Stepper motors are currently widely used in industries such as automatic control, stage lighting, textile machinery, medical instruments, and machining. Due to their high machining precision and small step angle, stepper motors are high-precision motors and require high environmental conditions for use.

[0003] With the development of applied science and technology, high-precision stepper motors are needed in harsh environments such as chemical industries and outdoor work sites, including monitoring and pan-tilt units. However, current stepper motors have relatively low mechanical protection levels. In harsh environments, dust often enters the motor bearings and internal components from the output shaft, easily damaging the bearings, corroding internal parts, degrading motor performance, causing rotor jamming, and reducing the insulation level of the motor coils, leading to internal coil breakdown or short circuits. This results in rapid motor damage and equipment failure, causing significant losses. Furthermore, over time, the weight of the motor end cap has gradually increased. Since motors have a short lifespan, the end cap is no longer usable after motor failure and must be recycled. The increased weight of the end cap actually increases the production cost of the motor. Therefore, we propose a new lightweight stepper motor end cap with a dustproof structure. Utility Model Content

[0004] The main purpose of this invention is to provide a lightweight stepper motor end cover with a dustproof structure, which can effectively solve the problems in the background art.

The side wall of the reinforcing frame is uniformly fixedly connected with a number of connecting ears, and the connecting ears correspond one-to-one with the slot. The connecting ears are fixedly connected to the dustproof partition by bolts.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Please see Figure 1-3This utility model provides a technical solution: a lightweight stepper motor end cover with a dustproof structure, comprising: an end cover body 1, a reinforcing frame 2 fixedly connected to one side of the end cover body 1, and a plurality of through-holes 11 evenly and annularly formed on one side of the reinforcing frame 2, which strengthens the structure of the end cover body 1, facilitates ventilation and heat exchange for the stepper motor, and achieves the lightweight requirement of the end cover body 1; an installation positioning ring 3 is provided at the center of the inner cavity on the other side of the end cover body 1 for easy installation and positioning, and also allows the end cover body 1 to be configured as... A housing effectively reduces the weight of the end cap body 1. The end cap body 1 has through mounting holes 4 at the four corners of its side wall to allow it to be installed in a suitable position on the housing of a stepper motor or other components. A sealing frame 5 has a dustproof mesh 6 inside its cavity, and a circular mesh frame 7 in the middle of the dustproof mesh 6. A dustproof partition 14 has several slots 13 evenly distributed on the side wall of the reinforcing frame 2, and each slot 13 corresponds to a heat dissipation slot 11. The dustproof partition 14 is slidably inserted into the cavity of the slot 13 to shield the heat dissipation slot 11 and prevent dust from entering the stepper motor from the heat dissipation slot 11.

[0021] Specifically, such as Figure 2 , Figure 4 As shown, the side wall of the sealing frame 5 is sealed to the inner cavity of the mounting positioning ring 3 via a sealing ring, and the circular mesh frame 7 is connected to the reinforcing frame 2 by several bolts. A dustproof mesh 6 is installed inside the sealing frame 5 to filter dust and impurities in the air, preventing dust and impurities from contacting the stepper motor and thus protecting it from dust. When it is necessary to clean the dustproof mesh 6, the bolts on the circular mesh frame 7 are removed, allowing the sealing frame 5, dustproof mesh 6, and circular mesh frame 7 to be separated from the reinforcing frame 2. This allows for the cleaning of the dustproof mesh 6, preventing excessive dust accumulation that could affect its subsequent dustproofing function and ensuring the efficient dustproofing effect of the end cover body 1.

[0022] Specifically, such as Figure 3 As shown, the inner cavity of slot 13 is equipped with a sealing ring that can be sealed to the dustproof partition 14. Several connecting ears 15 are evenly fixed to the side wall of the reinforcing frame 2, and each connecting ear 15 corresponds one-to-one with the slot 13. The connecting ears 15 are fixedly connected to the dustproof partition 14 by bolts. When the stepper motor is in a dusty environment, the dustproof partition 14 is inserted into the inner cavity of slot 13, and the connecting ears 15 on the reinforcing frame 2 are fixedly connected to the dustproof partition 14 by bolts. At this time, the sealing ring in the inner cavity of slot 13 can be sealed to the dustproof partition 14, effectively preventing external dust from entering the stepper motor cavity through the heat dissipation slot 11. When the external dust decreases, the bolts are removed, and the dustproof partition 14 is removed for cleaning, thus improving the heat dissipation performance of the stepper motor.

[0023] Specifically, such as Figure 3 , Figure 4As shown, a through hole 12 is opened in the middle of one side of the reinforcing frame 2. A dustproof bearing ring 8 is slidably engaged in the inner cavity of the circular mesh frame 7. A convex ring 9 is fixedly connected to one side of the dustproof bearing ring 8, and the convex ring 9 penetrates through the through hole 12 to the outside. A non-through bearing adapter groove 10 is opened on one side of the dustproof bearing ring 8. Both the dustproof bearing ring 8 and the convex ring 9 have sealing gaskets on their side walls, which can seal the connection with the through hole 12 and the side wall of the circular mesh frame 7. The side wall of the dustproof bearing ring 8 is fixedly connected to the side wall of the reinforcing frame 2 by several bolts. By setting the bearing adapter groove 10 to place the bearing, and by connecting the through hole 12 and the convex ring 9, the motor output shaft can pass through the through hole 12 and the convex ring 9 to exit the end cover body 1. At the same time, the dustproof bearing ring 8 and the convex ring 9 are fixedly connected to the reinforcing frame by bolts. This design improves the lightweight design of the end cover body 1 and facilitates disassembly and maintenance. When the dustproof bearing ring 8 or the convex ring 9 is damaged, it can be replaced individually without replacing the entire end cover body 1. Furthermore, the dustproof bearing ring 8 and the convex ring 9 are both equipped with sealing gaskets on their side walls, which can be sealed and connected with the central hole 12 and the side wall of the circular mesh frame 7, further improving the dustproof effect of the inner cavity of the end cap body 1.

[0024] It should be noted that this utility model is a lightweight stepper motor end cover with a dustproof structure. A dustproof mesh 6 is set in the inner cavity of the sealing frame 5 to filter dust and impurities in the air, preventing dust and impurities from contacting the stepper motor and thus playing a dustproof role. When it is necessary to clean the dustproof mesh 6, the bolts on the circular mesh frame 7 are removed, and the sealing frame 5, dustproof mesh 6, and circular mesh frame 7 can be separated from the reinforcing frame 2, allowing for cleaning of the dustproof mesh 6. This prevents excessive dust accumulation on the dustproof mesh 6 from affecting its subsequent dustproof work, ensuring the efficient dustproof effect of the end cover body 1. When the stepper motor is in a dusty environment, a dustproof partition 14 is inserted into the inner cavity of the slot 13, and the connecting lug 15 on the reinforcing frame 2 is fixedly connected to the dustproof partition 14 with bolts. At this time, the sealing ring in the inner cavity of the slot 13 can be sealed with the dustproof partition 14, thereby effectively preventing external dust from entering the inner cavity of the stepper motor through the heat dissipation groove 11. When the external dust decreases, remove the bolts and remove the dustproof partition 14 to clean the dustproof partition 14 and improve the heat dissipation performance of the stepper motor.

[0025] The heat dissipation groove 11 strengthens the structure of the end cover body 1 while facilitating ventilation and heat exchange for the stepper motor, achieving the lightweight requirement of the end cover body 1. The installation positioning ring 3 facilitates installation and positioning, allowing the end cover body 1 to be designed as a single shell, effectively reducing its weight. The bearing adapter groove 10 accommodates the bearing, and the connection between the central hole 12 and the convex ring 9 allows the motor output shaft to pass through the central hole 12 and the convex ring 9 to exit the end cover body 1. The dustproof bearing ring 8 and the convex ring 9 are fixedly connected to the reinforcing frame with bolts, further enhancing the lightweight design of the end cover body 1 and facilitating disassembly and maintenance. When the dustproof bearing ring 8 or the convex ring 9 is damaged, it can be replaced individually without replacing the entire end cover body 1. Furthermore, the sidewalls of the dustproof bearing ring 8 and the convex ring 9 are equipped with sealing gaskets, which can seal against the central hole 12 and the sidewalls of the circular mesh frame 7, further improving the dustproof effect of the end cover body 1's inner cavity.
