Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a micro motor that is easy to assemble and disassemble. Background Technology

[0002] In modern industry and daily life, micro motors are ubiquitous. From small motors that drive fans and regulate the opening and closing of doors and windows in smart home devices, to key components that control the movement of precision instruments and achieve precise operations in medical equipment, and to micro power sources that provide power for vibration feedback, lens focusing, and other functions in various portable electronic devices, micro motors have become an indispensable part of many products due to their small size and powerful functions. According to incomplete statistics, the global demand for micro motors in the consumer electronics field alone is as high as billions of units per year, and this number continues to rise with the booming development of emerging industries such as the Internet of Things and wearable devices.

[0003] The most common way to connect the end cap of a traditional micro motor to the motor body is by screw fastening. The principle is that the threads of the screw engage with the corresponding screw holes on the motor body and the end cap, thus firmly fixing the end cap to the motor. In some small DC micro motors, 2 to 4 micro screws are usually used to achieve this connection. This method seems reliable, but in actual operation, the micro screws are tiny, and operation requires the use of a special precision screwdriver. This requires a high level of skill and precision from the operator. On the assembly line, workers need to spend a lot of time aligning the screw holes and carefully tightening the screws, which greatly reduces assembly efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a micro motor that is easy to assemble and disassemble. This solves the problem that requires the use of a special precision screwdriver during operation, which requires a high level of technical skill and precision from the operator. On the assembly line, workers need to spend a lot of time aligning the screw holes and carefully tightening the screws, which greatly reduces the assembly efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a micro motor that is easy to assemble and disassemble, comprising a base and a micro motor body, wherein a limiting component is provided on the micro motor body; The limiting assembly includes an end cap, six protective covers, six fixing blocks, and six protrusions.

The inner walls of the six grooves are provided with first limiting block grooves, the outer walls of the six protrusions are provided with second limiting block grooves, and the interiors of the six second limiting block grooves are slidably connected with limiting blocks. The outer wall of the micro motor body near the end cover is fixedly connected with six fixing seats. The inner walls of the six protective covers are respectively in contact with the outer walls of the corresponding fixing seats. The interiors of the six second limiting block grooves are provided with reset springs, and the outer wall of the base near the end cover is provided with six push rod grooves.

[0018] Please see Figure 1-4This utility model provides a technical solution: a micro motor that is easy to assemble and disassemble, including a base 1 and a micro motor body 2. The micro motor body 2 is provided with a limiting component, which includes an end cap 3, six protective covers 4, six fixing blocks 5 and six protrusions 7. The six protrusions 7 are all fixedly installed on the outer wall of the end cap 3, and the six fixing blocks 5 are correspondingly fixedly installed on the outer wall of the protective covers 4. The inner wall of the micro motor body 2 is provided with six grooves 6. The outer wall of the end cap 3 is slidably connected to the inner wall of the micro motor body 2. The inner wall of each of the six grooves 6 is provided with a first limiting block groove 9. The outer wall of each of the six protrusions 7 is provided with a second limiting block groove 11. The interior of each of the six second limiting block grooves 11 is slidably connected with a limiting block 8. The outer wall of the micro motor body 2 near the end cap 3 is fixedly connected with six fixing seats 13. The inner walls of the six protective covers 4 are respectively in contact with the outer walls of the corresponding fixing seats 13. The interior of each of the six second limiting block grooves 11 is provided with a return spring 12. The outer wall of the base 1 near the end cap 3 is provided with six push rod grooves 10.

[0019] The outer walls of the six protrusions 7 are slidably connected to the interior of the corresponding grooves 6. The ends of the six limiting blocks 8 near the first limiting block groove 9 are slidably extended into the interior of the groove 6 and are slidably connected to the interior of the corresponding first limiting block groove 9. The two ends of the six return springs 12 are fixedly connected to the outer walls of the corresponding limiting blocks 8 and the inner walls of the second limiting block groove 11. The interiors of the six push rod grooves 10 are respectively connected to the interiors of the corresponding first limiting block grooves 9. The six protective covers 4 are installed on the fixing base 13 by bolts on the fixing block 5. The six push rod grooves 10 are respectively located inside the corresponding protective cover 4. The mounting shaft 14 is installed inside the micro motor body 2. The end of the mounting shaft 14 near the end cover 3 is rotatably extended to the outside of the end cover 3. The micro motor body 2 is fixedly installed on the upper surface of the base 1. When the fixing block 5 is a magnetic fixing block 15, the magnetic blocks on the magnetic fixing block 15 are used in conjunction with the six magnetic seats on the outer wall of the end of the base 1 near the end cover 3.

[0020] Example 1: Please refer to Figure 1-4 Example of disassembly and assembly of conventional industrial equipment foundations (mounting block foundation) This embodiment is applicable to micro motors in ordinary industrial equipment (such as small conveyor belt drives). The end cover can be disassembled and reassembled for daily maintenance through the mounting block and the basic limiting structure, which meets the routine maintenance needs. Structural assembly and disassembly process: The fixing block 5 is a conventional positioning mounting block (Q235 steel material), which is fixed to the micro motor body 2 by bolts (tightening torque 8N・m). The limiting block 8 is made of 45# steel (length 8mm). The spring force of the reset spring 12 is set to 5N to ensure that the limiting block is stably embedded in the first limiting block groove 9 (clamping force ≥7N). The end cover 3 is made of aluminum alloy, and the protrusion 7 and the groove 6 slide together (gap ≤0.1mm). During maintenance, first unscrew the bolts on the mounting block and remove the protective cover 4. Use the standard tool push rod (3mm in diameter) to insert into the push rod groove 10 and push the limit block to compress the reset spring (push force ≤6N) so that it is disengaged from the first limit block groove. Simultaneously, pull out the end cover along the groove 6 (pull force ≤10N) to complete the disassembly (the whole process takes ≤2 minutes). During installation, the protrusion guides the end cover to accurately reset, and the limit block automatically springs into the groove and locks, ensuring that the end cover does not loosen when the motor is running (vibration amplitude ≤0.05mm). Application effect: The basic structure is easy to disassemble and assemble under normal working conditions. After 300 hours of continuous use, the end cover does not loosen. It is suitable for daily maintenance of micro motors in industrial equipment such as textile machinery and small pumps.

[0021] Example 2: Please refer to Figure 5 Automated production line rapid assembly and disassembly example (magnetic fixing block replacement) This embodiment is designed for micro motors in automated production lines (such as 3C product assembly lines). It uses magnetic fixing blocks to improve the efficiency of protective cover assembly and disassembly, and reduce production line downtime. Structural optimization and magnetic compatibility: The fixing block 5 is replaced with a magnetic fixing block 15 (neodymium iron boron magnet, attraction force ≥12N), and a low carbon steel magnetic seat is set at the corresponding position of the base 1 to achieve "magnetic fixing + boltless connection". The surface of the limiting block 8 is chrome-plated for rust prevention, and the spring force of the reset spring 12 is increased to 6N to meet the high frequency of disassembly and assembly requirements of the production line. A positioning notch is added to the edge of the protective cover 4 to cooperate with the magnetic fixing block for positioning (deviation ≤0.2mm).

[0022] When changing models on the production line, the protective cover can be removed without tools (overcoming the magnetic pull force of 12N), the push rod pushes the limit block away from the tank (thrust force ≤7N), the end cover is pulled out smoothly, and the magnetic fixing block automatically adsorbs the protective cover during installation (the alignment time is shortened by 60%). After the end cover is reset, the limit block is quickly locked, and the disassembly and assembly time of a single motor is reduced from 2 minutes to 40 seconds. Production line compatibility: The magnetic structure improves production line maintenance efficiency by 70%, and the boltless design reduces tool dependence, making it suitable for quick changeover of micro motors in automated scenarios such as mobile phone production lines and small robots.

[0023] Furthermore, when using this device, firstly, the micro motor body 2 is fixedly installed on the upper surface of the base 1 to complete the assembly of the basic structure. Then, the end cap 3 is installed onto the micro motor body 2. During installation, the six protrusions 7 on the outer wall of the end cap 3 are aligned with the six grooves 6 on the inner wall of the micro motor body 2. Then, the end cap 3 is slid into the micro motor body 2 along the grooves 6. During the pushing process, the limiting block 8 on the protrusion 7 is squeezed by the inner wall of the groove 6, which will compress the return spring 12 in the second limiting block groove 11, causing the limiting block 8 to retract into the second limiting block groove 11. When the end cap 3 slides to the appropriate position... When the second limiting block groove 11 on the protrusion 7 is aligned with the first limiting block groove 9 on the inner wall of the groove 6, the limiting block 8 pops out under the elastic force of the return spring 12, slides into the interior of the groove 6 and is locked into the corresponding first limiting block groove 9, thus achieving the limiting and fixing of the end cover 3 and the micro motor body 2. Then, the protective cover 4 is installed according to the type of fixing block 5. If the fixing block 5 is a mounting block, the six protective covers 4 are respectively installed on the outer wall of the micro motor body 2 near the end cover 3 by bolts, so that each protective cover 4 covers a corresponding top rod groove. 10. If the fixing block 5 is a magnetic fixing block 15, the protective cover 4 is installed and fixed by mutual attraction between the magnetic block on the magnetic fixing block 15 and the magnetic seat on the base 1. At this time, the end of the mounting shaft 14 near the end cover 3 rotates and extends to the outside of the end cover 3, and the entire motor assembly is completed. Then, when it is necessary to disassemble, repair or replace parts of the motor, first remove the protective cover 4. If the fixing block 5 is a mounting block, unscrew the bolts on the fixing block 5 to remove the six protective covers 4 from the micro motor body 2. If the fixing block 5 is a magnetic fixing block 15, directly remove the magnetic fixing block 15. After separating from the magnetic base on the base 1, the protective cover 4 can be removed. After the protective cover 4 is removed, the top rod groove 10 on the base 1 is exposed. Use a suitable tool to insert into the top rod groove 10. Since the top rod groove 10 is connected to the inside of the first limiting block groove 9, the tool can push the limiting block 8 in the first limiting block groove 9, so that the limiting block 8 compresses the reset spring 12 and retracts into the second limiting block groove 11, releasing the limiting effect of the limiting block 8 on the end cover 3. At this time, slide the end cover 3 outward along the groove 6 to remove the end cover 3 from the micro motor body 2, so that the internal components of the motor can be inspected or replaced.

[0024] The end cap 3 of the limiting component is slidably connected to the groove 6 on the inner wall of the micro motor body 2 via the protrusion 7. During assembly, simply align the six protrusions 7 on the outer wall of the end cap 3 with the groove 6 and slide it in along the groove 6. During the pushing process, the limiting block 8 on the protrusion 7 is squeezed and compressed by the inner wall of the groove 6, and the return spring 12 retracts into the second limiting block groove 11. When it slides to the appropriate position, the limiting block 8 pops out under the action of the return spring 12 and is locked into the first limiting block groove 9, thereby achieving the limiting and fixing of the end cap 3. The whole process does not require the use of special tools such as precision screwdrivers, and the operation is simple and convenient, which greatly shortens the end cap assembly time.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
