in order to prevent the outside environment from polluting the inside of the stepping motor 1, the present apparatus can be used in a dust-free environment.
Specifically, the air-cooled heat dissipation mechanism 2 is provided with a fan 206 and an air duct 207; the fan 206 is fixedly installed on the motor shaft 101 of the stepping motor 1; the air pipe 207 is fixedly arranged on the shell 102 through 4 support rods 208, the air inlet corresponds to the fan 206, and the air outlet corresponds to the hollowed-out part of the shell 102;

As a specific implementation manner of this embodiment, as shown in fig. 2 to 9, a guiding wheel 201, a centrifugal wheel 202, a counterweight centrifugal block 204 and a sliding rail 209 are arranged on the second driving device; the guide wheel 201, the centrifugal wheel 202 and the motor shaft 101 are coaxially arranged; the guide wheel 201 is fixedly arranged on the motor shaft 101, and two guide rods which are obliquely upwards are uniformly and fixedly arranged on the outer side of the guide wheel; the centrifugal wheel 202 is slidably mounted on the motor shaft 101 in the axial direction; the centrifugal wheel 202 is positioned above the guide wheel 201 and is elastically connected with the fan 206; one end of each of the 2 counterweight centrifugal blocks 204 is elastically and slidably arranged on the centrifugal wheel 202 through a second reset spring 212, and the other end of each of the 2 counterweight centrifugal blocks is slidably arranged on the guide wheel 201, and the guide rods on the guide wheels 201 correspond to each other and slide along the guide rods; two symmetrical sliding rods 203 are rotatably arranged on the centrifugal wheel 202; the other end of the sliding rod 203 is slidably arranged on the sliding rail 209; one end of the sliding rail 209 is fixedly arranged on the shell 102, and the other end is fixedly arranged at the position of an air outlet of the fan 206; the slide bar 203 is rotatably provided with a connecting rod 210; the other end of the connecting rod 210 is rotatably connected with a linkage rod 211, and the other ends of the two linkage rods 211 are respectively rotatably connected with one ends of a plurality of shading strips 213.
The fan 206 is driven to rotate by the rotation of the motor shaft 101, so that the wind flow is transmitted into the stepping motor 1 through the air inlet of the air pipe 207, and the wind flow entering the air pipe 207 can be automatically adjusted according to the rotation speed of the motor shaft 101;
specifically, in the initial state, the plurality of light shielding strips 213 block the air inlet of the air duct 207; when the rotation speed of the motor shaft 101 increases, the rotation speed of the centrifugal wheel 202 on the motor shaft 101 synchronously increases, so that the counterweight centrifugal block 204 is thrown out, the counterweight centrifugal block 204 slides outwards relative to the centrifugal wheel 202, the counterweight centrifugal block 204 slides out due to strong centrifugal force, and the outer side end of the counterweight centrifugal block 204 is in sliding connection with an inclined slide rail which guides the wheel 201 to synchronously rotate with the motor shaft 101, so that the counterweight centrifugal block 204 drives the centrifugal wheel 202 to slide towards the direction of the fan 206, thereby driving the slide bar 203 to slide, and the slide bar 203 drives the linkage bar 211 to rotate upwards through the connecting rod 210, thereby driving the plurality of wind shielding strips 213 to rotate, opening the wind gap and enabling wind flow to enter the wind pipe 207 through gaps between the wind shielding strips;
when the rotating speed of the motor shaft 101 is higher, larger heat is generated, and the air quantity entering the air pipe is increased, so that the cooling effect is better; the higher the rotation speed of the motor shaft 101 is, the farther the counterweight centrifugal block 204 is thrown out of the centrifugal wheel 202, so that the distance that the centrifugal wheel 202 moves upwards is larger, the larger the rotation angle of the air shielding strip 213 is, the larger the air quantity entering the air pipe 207 is, the air flow flowing into the stepping motor 1 is increased, and the cooling effect is greatly improved.
When the motor shaft 101 stops rotating, in order to reset the centrifugal wheel 202, the centrifugal wheel 202 and the fan 207 are elastically connected through the first reset spring 205, so that the centrifugal wheel 202 is reset under the action of the first reset spring 205 when the motor shaft 101 stops rotating, and the balance weight centrifugal block 204 and the air shielding strip 213 are driven to be reset together in the resetting process of the centrifugal wheel 202.
Specifically, as shown in fig. 10 and 12, the water cooling mechanism 3 is provided with a cooling liquid pipeline 301 and a thumb wheel 306; the coolant pipe 301 is fixedly installed on the housing 102; the thumb wheel 306 is rotatably arranged inside the cooling liquid pipeline 301 and is driven by a driving device arranged on the motor shaft 101 to drive cooling liquid in the cooling liquid pipeline 301 to flow;
as a specific implementation of this embodiment, as shown in fig. 10-12, a centrifugal wheel two 302 is provided on the driving device; the centrifugal wheel II 302, the poking wheel 306 and the motor shaft 101 are coaxially arranged; the centrifugal wheel II 302 is fixedly arranged on the motor shaft 101 and rotatably arranged at the upper end of the cooling liquid pipeline 301; the centrifugal wheel two 302 is uniformly and slidably provided with 4 counterweight centrifugal blocks two 303, 3 groups of strong magnets 305 are arranged on the counterweight centrifugal blocks two 303 along the radial direction of the centrifugal wheel two 302, and each group is provided with two strong magnets 305; the thumb wheel 306 is divided into an upper layer and a lower layer, and each layer can rotate independently; the strong magnets 307 on each layer of thumb wheel 306 from top to bottom are sequentially arranged from inside to outside; each layer is provided with 4 blades, each blade is fixedly provided with two strong magnets 307 corresponding to the strong magnets 305, and the strong magnets 307 on the three layers of the thumb wheel 306 from top to bottom are correspondingly matched with the three groups of strong magnets 305 on the counterweight centrifugal block two 303 in sequence; the second strong magnet 307 on the uppermost thumb wheel 306 is closest to the axle center and then sequentially far away from the axle center from top to bottom; the thumb wheel 306 is divided into three layers, and the cooling effect can be adjusted according to the rotation speed of the motor shaft 101.
When the water cooling mechanism is in operation, the motor shaft 101 rotates to drive the centrifugal wheel II 302 at the water cooling position to rotate so as to drive the counterweight centrifugal block II 303 to rotate, and three groups of strong magnets are arranged on the counterweight centrifugal block II 303, and when the centrifugal wheel II 302 rotates, the strong magnet 305 at the outermost side of the centrifugal wheel II 302 is parallel to the strong magnet II 307 on the poking wheel 306 at the uppermost layer and corresponds to the centrifugal wheel II in the vertical direction; when the motor shaft 101 rotates, the closest group of poking wheels 306 is driven to rotate, as the motor shaft 101 rotates faster, the strong magnet II 307 on the poking wheels 306 cannot catch up with the strong magnet 305 on the centrifugal wheel II 303 when the motor shaft 101 starts to rotate, but the poking wheels 306 gradually accelerate until the cooling liquid in the cooling liquid pipeline 301 rotates at a constant speed, when the motor shaft 101 rotates at a constant speed, the counterweight centrifugal block II 303 is thrown out, and when the second group of strong magnets 305 on the counterweight centrifugal block II 303 extends out, the strong magnet 305 on the outermost group of strong magnets 305 is parallel to the strong magnet II 307 on the middle poking wheels 306 and corresponds to the strong magnet II 307 on the middle poking wheels in the vertical direction; the second set of strong magnets 305 on the second counterweight centrifugal block 303 is matched with the second set of strong magnets 307 on the uppermost thumb wheel 306, so that the two sets of thumb wheels 306 are driven to rotate at the moment, the middle thumb wheel 306 is gradually accelerated until the speed is uniform, and the flow rate of the cooling liquid is faster at the moment, and the cooling effect is better; when the second counterweight centrifugal block 303 is completely thrown out, the three groups of strong magnets 305 on the second counterweight centrifugal block are respectively parallel to the strong magnets on the three groups of thumb wheels and are correspondingly matched in the vertical direction; therefore, the three groups of thumb wheels 306 are driven to rotate, the magnetic force is weakened because the distance between the third group of thumb wheels 306 and the counterweight centrifugal block II 303 is overlarge, and the driving can be more time consuming originally, but because the cooling liquid flows when the first two groups of thumb wheels 306 rotate, the rotation resistance of the third group of thumb wheels 306 is reduced, thereby balancing the attenuation caused by magnetic distance, the three groups of thumb wheels 306 can rotate synchronously quickly, the cooling liquid in the cooling liquid pipeline 301 flows, the heat on the shell 102 is taken away more quickly, and the cooling effect is achieved.
In this embodiment, in order to accelerate cooling of the coolant pipe 301, a second fan (not shown in the figure) is arranged outside the device and is directly blowing air to the coolant pipe 301, so as to take away heat on the coolant pipe 301 faster and accelerate cooling.
