Description

Technical Field

[0001] The utility model relates to the technical field of high-torque motors, in particular to a high-torque motor with an integrated heat dissipation structure. Background Art

[0002] At present, with the continuous development of the machinery industry, stepper motors have been widely used, and there are more and more studies on the control of stepper motors. Stepper motors use the principle of electromagnets to convert electrical pulse signals into corresponding angular displacement and linear displacement. There are many types of stepper motors, which can be divided into reluctance stepper motors, permanent magnet stepper motors, and hybrid magnetic stepper motors.

[0003] There are many existing technologies for high torque motors, such as:

However, when the high-torque motor is installed and used, the brush needs to be disassembled, which is inconvenient to clean the high-torque motor at any time. In addition, during the cleaning process, dust will inevitably enter the interior of the casing, causing clogging of the internal parts of the high-torque motor, affecting the use of the high-torque motor, not only reducing the service life of the high-torque motor, but also reducing the heat dissipation effect of the high-torque motor, thereby reducing the practicality of the high-torque motor.

[0006] In view of this, we propose a high-torque motor with an integrated heat dissipation structure. Utility Model Content

[0026] Most high-torque motors will install a brush on the rotating shaft. The rotation of the high-torque motor drives the brush to rotate and clean the outer wall of the casing. However, when the high-torque motor is installed and used, the brush needs to be removed, which is inconvenient to clean the high-torque motor at any time. In addition, during the cleaning process, dust will inevitably enter the interior of the casing, causing clogging of the internal parts of the high-torque motor, affecting the use of the high-torque motor, not only reducing the service life of the high-torque motor, but also reducing the heat dissipation effect of the high-torque motor, thereby reducing the practicality of the high-torque motor.

[0027] See also Figure 1-Figure 5 The embodiment of the utility model shown in the figure comprises a rotating shaft 10, the outer wall of the rotating shaft 10 is provided with a chassis 11, the upper surface of the chassis 11 is provided with a casing assembly 12 for enhancing the heat dissipation effect, the upper surface of the casing assembly 12 is provided with a heat dissipation assembly 13, and the outer wall of the rotating shaft 10 located on the upper surface of the chassis 11 is provided with a cleaning assembly 20 for cleaning dust from the casing assembly 12, wherein: the cleaning assembly 20 and the heat dissipation assembly 13 are both installed on the outer wall of the rotating shaft 10, and the cleaning assembly 20 and the heat dissipation assembly 13 are driven by the rotation of the rotating shaft 10 to dissipate heat for the high-torque motor.

[0028] First, the specific structure of the casing assembly 12 is disclosed. The casing assembly 12 at least includes a bottom ring 121. The upper surface of the chassis 11 is provided with the bottom ring 121. The upper surface of the bottom ring 121 is provided with a plurality of heat dissipation fins 122. The plurality of heat dissipation fins 122 are arranged in a circular array, and the upper surfaces of the plurality of heat dissipation fins 122 are provided with a top ring 123.

[0029] The improvement lies in that: through the gaps between multiple cooling fins 122, not only the heat dissipation area is increased, but also air flow can be formed when the high-torque motor rotates, thereby enhancing the heat dissipation effect, increasing the service life of the high-torque motor, reducing the frequency of high-torque errors, and improving the use effect of the high-torque motor, thereby improving the practicality of the high-torque motor.

[0030] Secondly, the specific structure of the heat dissipation component 13 is disclosed. The heat dissipation component 13 at least includes a mounting shell 131. The mounting shell 131 is disposed on the upper surface of the top ring 123. The other end of the rotating shaft 10 is rotatably connected to the inner wall of the mounting shell 131. A fan blade 132 is disposed at one end of the rotating shaft 10 close to the interior of the mounting shell 131. A connecting frame 133 is disposed on the outer wall of the rotating shaft 10 below the fan blade 132. A number of heat dissipation holes 134 are opened on the top of the mounting shell 131.

[0031] The improvement lies in that the fan blades 132 are driven to rotate by the rotation of the rotating shaft 10, and at the same time, the internal part of the high-torque motor is cooled and the heat is discharged through multiple heat dissipation holes 134, which is beneficial to improving the heat dissipation effect of the high-torque motor, increasing the service life of the high-torque motor, avoiding economic losses, and thus improving the practicality of the high-torque motor.

[0032] The specific structure of the cleaning component 20 is disclosed again. The cleaning component 20 at least includes a mounting ring 21. The mounting ring 21 is provided on the outer wall of the rotating shaft 10 on the upper surface of the chassis 11. Connecting rods 22 are provided on both sides of the mounting ring 21. A mounting rod 23 is provided on the side of the connecting rod 22 away from the mounting ring 21. A cleaning plate 25 is plugged into and matched with the side of the mounting rod 23 away from the connecting rod 22 through a mounting component 24, and a brush 26 is provided on the other side of the cleaning plate 25.

[0033] The improvement lies in that the two connecting rods 22 are driven to rotate by the rotation of the rotating shaft 10, and at the same time, the brush 26 cleans the housing assembly 12 to prevent dust clogging and affect the heat dissipation efficiency of the cooling fins 122. It also reduces the frequency of failures during use of the high-torque motor, thereby increasing the service life of the high-torque motor and avoiding economic losses.

[0034] Then, the specific structure of the mounting assembly 24 is disclosed. The mounting assembly 24 at least includes an elastic member 241. Elastic members 241 are provided inside both ends of the cleaning plate 25. A connecting plate 242 is provided at the other end of the elastic member 241. A plug plate 244 is provided on the side of the connecting plate 242 extending to the outside of the cleaning plate 25. A control plate 243 is provided on the side of the connecting plate 242 away from the elastic member 241. A groove 245 for inserting the connecting plate 242 is provided on one side of the mounting rod 23, and a slot 246 for plugging and mating with the plug plate 244 is provided inside the groove 245.

[0035] The improvement lies in that: the control plate 243 is pressed in the direction of the cleaning plate 25 to cause the elastic member 241 to deform and contract. At this time, the connecting plate 242 and the plug plate 244 are inserted into the interior of the groove 245, and then the control plate 243 is released. Through the resilience of the elastic member 241, the plug plate 244 is bounced into the interior of the slot 246 and plugged in with it, so that the cleaning plate 25 can be installed. It is also convenient to disassemble, which facilitates the later replacement of the brush 26 and prevents the brush 26 from being damaged due to long-term use, which affects the cleaning effect of the housing assembly 12. It also improves the flexibility of the high-torque motor, thereby increasing the service life of the high-torque motor.

[0036] In summary, the working principle of the present scheme is as follows: first, press the control plate 243 in the direction of the cleaning plate 25 to cause the elastic member 241 to deform and contract. At this time, insert the connecting plate 242 and the plug plate 244 into the groove 245, and then release the control plate 243. Through the resilience of the elastic member 241, the plug plate 244 is bounced into the slot 246 and plugged in with it, so that the cleaning plate 25 can be installed. After that, the high-torque motor is powered on to make it work. Through the rotation of the high-torque motor rotating shaft 10, the two connecting rods 22 are driven to rotate, so that the brush 26 cleans the gaps between the multiple cooling fins 122. At the same time, the fan blades 132 are driven to rotate to dissipate heat inside the high-torque motor, and the heat is discharged through the multiple cooling holes 134, so that the heat dissipation of the high-torque motor can be completed.
