Description

Technical Field

[0001] This utility model relates to the field of compact stepper motor technology, specifically to a compact reactive stepper motor. Background Technology

[0002] A stepper motor is an open-loop control motor that converts electrical pulse signals into angular or linear displacement. Its rotation angle and speed are proportional to the input pulse. It achieves precise control through fixed-angle steps and is widely used in fields that require high-precision positioning and speed control. Its working principle is based on the alternating changes of magnetic fields and the interaction of magnetic poles. By controlling the direction and sequence of the current in the stator windings, a rotating magnetic field can be generated, thereby attracting or repelling the rotor and making it rotate according to a predetermined step angle.

[0003] Existing compact reactive stepper motors mostly use a one-piece housing, making it difficult to inject lubricating oil into the central shaft and stabilizing bearing after installation to ensure stable rotation. This leads to difficulty in injecting lubricating oil after prolonged use, causing rotational difficulties. Utility Model Content

[0004] The purpose of this invention is to provide a compact reactive stepper motor to solve the above problems. Through the cooperation between the stabilizing mechanism and the lubrication mechanism, lubricating oil is provided to the connection between the rotor's central shaft and the stabilizing mechanism, thereby improving the stable output effect of the central shaft.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A compact reactive stepper motor includes: a motor structure, a front end cover fixedly mounted on the motor structure, a stabilizing mechanism fixedly mounted on the front end cover, and an oil injection mechanism slidably mounted on the stabilizing mechanism;

[0007] The motor structure includes an integral housing, the stabilizing mechanism includes a stabilizing ring, the stabilizing ring has a placement groove, the placement groove is fixedly provided with a first fixing plate, the first fixing plate is rotatably provided with a threaded rod, the first fixing plate is fixedly provided with a second fixing plate, and the second fixing plate is fixedly provided with an oil injection pipe.

[0008] Furthermore, the oil injection pipe is fixedly equipped with a top rod, and the oil injection pipe passes through the second fixing plate.

[0009] Furthermore, a damping ring is fixedly provided on the threaded rod.

[0010] Furthermore, the oil injection mechanism includes a lifting plate, on which an oil delivery pipe is fixedly installed. The oil delivery pipe passes through the lifting plate and has a top hole.

[0011] Furthermore, the oil delivery pipe is fixedly equipped with a support frame, and the support frame is fixedly equipped with a telescopic spring.

[0012] Furthermore, the telescopic spring is fixedly provided with a blocking rod, the diameter of which is larger than the top hole.

[0013] Furthermore, the integrated housing is fixedly provided with a stator, the integrated housing is rotatably provided with a central shaft, and the central shaft is fixedly provided with a rotor.

[0014] Furthermore, a miniature fan is fixedly mounted on the central shaft, and a through-heat dissipation slot is provided between the stator and the integrated housing.

[0015] Furthermore, the front end cover includes a fixed cover, which is provided with a through hole, a bolt hole and a vent hole, and a fixed bolt is threaded through the fixed cover. There are four bolt holes, four vent holes and four fixed bolts.

[0016] Furthermore, each of the four exhaust vents is fixedly equipped with a heat dissipation fin, and each of the four heat dissipation fins is fixedly equipped with a filter screen.

[0017] A miniature fan fixed to the central shaft rotates after the rotor rotates, causing the miniature fan to rotate and generate airflow to dissipate heat from the inside of the unibody casing. The hot air is then expelled through the exhaust vents. At the same time, heat dissipation fins fixed to the exhaust vents work together to dissipate heat, improving the heat dissipation effect inside the unibody casing. A filter prevents dust from entering the unibody casing.

[0018] In summary, the beneficial effects of this utility model are as follows: through the cooperation between the stabilizing mechanism and the lubrication mechanism, the operator can quickly inject lubricating oil between the central shaft and the stabilizing mechanism, thereby improving the convenience of subsequent maintenance.

[0019] The integrated housing supports the stator and rotor, further reducing the internal space of the motor and making the product more compact. At the same time, the front cover, together with the miniature fan on the central shaft, dissipates heat from the integrated housing, improving the rotor's working efficiency and preventing excessive internal temperature from affecting work efficiency.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] See Figures 1-3 and Figure 6 As shown, this utility model provides a compact reactive stepper motor, including: a motor structure 1, a front end cover 2 fixedly mounted on the motor structure 1, a stabilizing mechanism 3 fixedly mounted on the front end cover 2, and an oil injection mechanism 4 slidably mounted on the stabilizing mechanism 3;

[0032] Using the above technical solution, the motor is supported by the motor structure 1, the motor structure 1 is closed by the front cover 2, the motor shaft is further stabilized by the stabilizing mechanism 3 to prevent it from shaking during rotation, and the lubrication mechanism 4 and the stabilizing mechanism 3 work together to inject lubricating oil into the contact position between the motor shaft and the stabilizing mechanism 3 to improve the lubrication effect.

[0033] See Figure 6 and Figure 7 As shown, the stabilizing mechanism 3 includes a stabilizing ring 301, which has a placement groove 302. A first fixing plate 303 is fixedly mounted on the placement groove 302. A threaded rod 304 is rotatably mounted on the first fixing plate 303. A second fixing plate 306 is fixedly mounted on the first fixing plate 303. An oil injection pipe 307 is fixedly mounted on the second fixing plate 306. A push rod 308 is fixedly mounted on the oil injection pipe 307. The oil injection pipe 307 passes through the second fixing plate 306. A damping ring 305 is fixedly installed on the threaded rod 304. The oil injection mechanism 4 includes a lifting plate 401. An oil delivery pipe 402 is fixedly installed on the lifting plate 401. The oil delivery pipe 402 passes through the lifting plate 401 and has a top hole 403. A support frame 404 is fixedly installed on the oil delivery pipe 402. A telescopic spring 405 is fixedly installed on the support frame 404. A blocking rod 406 is fixedly installed on the telescopic spring 405. The diameter of the blocking rod 406 is larger than that of the top hole 403.

[0034] In use, the stabilizing ring 301 and the motor shaft provide support for stable rotation. The placement slot 302 supports the first fixing plate 303 and the second fixing plate 306. A threaded rod 304 works in conjunction with the lifting plate 401. A damping ring 305 at the top of the threaded rod 304 facilitates gripping and driving. The second fixing plate 306 supports the oil injection pipe 307, allowing one end to extend upwards and the other end to extend inwards towards the stabilizing ring 301. A push rod 308 inside the oil injection pipe 307 works in conjunction with a blocking rod 406 inside the oil delivery pipe 402 to open the oil delivery path. The lifting plate 401 adjusts the height of the oil delivery pipe 402. When the lifting plate 401 descends, it lowers the oil delivery pipe 402, allowing the oil delivery path to be opened. The lower end of the oil pipe 402 is fitted inside the upper end of the oil injection pipe 307. At this time, the push rod 308 gradually passes through the top hole 403 and pushes the blocking rod 406 upward. The diameter of the top hole 403 is larger than that of the push rod 308, so that after the push rod 308 pushes the blocking rod 406 upward, the lubricating oil is sent from the inside of the oil delivery pipe 402 into the inside of the oil injection pipe 307 through the distance between the push rod 308 and the top hole 403. The support frame 404 supports the telescopic spring 405. The telescopic spring 405 itself allows the blocking rod 406 to be adjusted in longitudinal height, providing space for the push rod 308 to push. After the push rod 308 is disengaged, the blocking rod 406 is reset and the top hole 403 is blocked again to prevent lubricating oil leakage. The blocking rod 406, with a diameter larger than that of the top hole 403, seals the top hole 403 to prevent lubricating oil leakage from the oil delivery hole.

[0035] See Figures 3-5 As shown, the motor structure 1 includes an integrated housing 101, a stator 102 fixedly mounted on the integrated housing 101, a central shaft 104 rotatably mounted on the integrated housing 101, a rotor 106 fixedly mounted on the central shaft 104, a miniature fan 105 fixedly mounted on the central shaft 104, a through heat dissipation groove 103 between the stator 102 and the integrated housing 101, and a front end cover 2 including a fixing cover 201, which has through holes 203, bolt holes 204 and vent holes 205 respectively. A fixing bolt 202 is threaded through the fixing cover 201, and there are four bolt holes 204, four vent holes 205 and four fixing bolts 202. Each of the four vent holes 205 is fixedly mounted with a heat dissipation fin plate 206, and each of the four heat dissipation fin plates 206 is fixedly mounted with a filter screen 207.

[0036] In the above embodiment, the injection molding of the integrated housing 101 reduces the internal space, making the stator 102 and rotor 106 more compact and supporting them. The rotation of the rotor 106 is transmitted through the central shaft 104, which in turn drives the micro fan 105 to rotate. The rotation of the micro fan 105 generates airflow inside the integrated housing 101, which, together with the exhaust vent 205, dissipates internal heat. The connection and fixation between the fixed cover 201 and the integrated housing 101 are completed by the four fixing bolts 202 in the fixed cover 201 through the heat dissipation groove 103. At the same time, the airflow generated by the micro fan 105 is allowed to flow through the gap, dissipating heat from the stator 102. The heat dissipation fins 206, together with the airflow expelled through the exhaust vent 205, further improve the heat dissipation effect. The filter 207 blocks impurities in the airflow.

[0037] With the above structure, when lubricating oil needs to be injected into this product, the operator first holds the damping ring 305 and rotates it. Through the thread between the threaded rod 304 fixed on the lower side of the damping ring 305 and the lifting plate 401, the lifting plate 401 is lowered. During the descent of the lifting plate 401 into the placement groove 302, the diameter of the oil supply pipe 402 is smaller than that of the oil injection pipe 307, so the oil supply pipe 402 is inserted into the oil injection pipe 307. As it continues to descend, the push rod 308 on the inner side of the oil injection pipe 307 passes through the top hole 403 and pushes the blocking rod 406 upward. At this time, the diameter of the top hole 403 is larger than that of the push rod 308. After the push rod 308 pushes the blocking rod 406 upward, the lubricating oil can flow into the oil injection hole through the space between the push rod 308 and the top hole 403, and then be delivered into the stabilizing mechanism 3 through the oil injection hole, providing lubricating oil to the contact position between the central shaft 104 and the stabilizing ring 301, thus improving the lubrication effect.

[0038] The miniature fan 105, fixed by the central shaft 104, rotates after the rotor 106 rotates, causing the miniature fan 105 to generate airflow to dissipate heat from the interior of the integrated housing 101. The hot air is then expelled through the exhaust port 205. At the same time, the heat dissipation fin plate 206, which is fixedly installed on the exhaust port 205, works in conjunction with the exhaust port 205 to dissipate heat, thereby improving the heat dissipation effect of the front part of the integrated housing 101. The filter 207 prevents dust from entering the interior of the integrated housing 101.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
