Description

Technical Field

[0001] This utility model relates to the field of micro motor direction measurement technology, and in particular to a micro motor steering measurement device. Background Technology

[0002] Micro motors are small motors with output power typically below several hundred watts, usually less than 160mm in diameter or less than 750mW, and operating between 1-24V. Micro motors are generally characterized by their compact structure and ease of integration, and are commonly used in control systems or transmission mechanical loads to perform functions such as detection, analysis, amplification, execution, or conversion of electromechanical signals or energy. The applications of micro motors are very broad, including but not limited to smartphones, small drones, precision medical devices, and smart home devices, where space and energy consumption are critical. Furthermore, micro motors are widely used in industrial automation, office automation, and home automation, such as in automobiles, home appliances, electric vehicles, speakers, and communication equipment. Although the internal structure of a micro motor is small, it is fully functional. For example, a micro DC motor includes key components such as the armature core, armature windings, and commutator; these components work together to enable the micro motor to operate efficiently and meet various application requirements.

[0003] In the production process of micro motors, load measurement is often performed using a fan-type load method due to the high cost of electromagnetic brakes. This fan-type load method requires an encoder to determine the motor's direction of rotation, necessitating the addition of a sensor and direction signal acquisition, making the process cumbersome, structurally complex, and significantly increasing equipment costs and maintenance difficulties. Furthermore, for circumferential motor measurements, securing the load to the motor shaft is challenging, impacting production efficiency. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a micro motor steering measurement device, which more accurately solves the issues of the cumbersome process, complex structure, and impact on production efficiency in measuring the direction of micro motors.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model proposes a micro motor steering measurement device, including a body, a control box is provided on one side of the top of the body, and motor support plates are fixedly connected to the outer wall of the top of the body by screws. The motor support plates are provided with a measuring component, which includes a motor base placed on the inner wall of the motor support plate, a motor under test fixedly connected to the outer wall of the motor base, a coupling installed on the output shaft of the motor under test, a fan blade connecting shaft installed on the bottom outer wall of the coupling, and a load fan blade welded to the bottom outer wall of the fan blade connecting shaft.

[0007] In the above scheme, a measurement method using a one-way bearing embedded in a coupling is adopted. The coupling is then fixed on the fan blade connecting shaft of the load fan blade. After the output shaft of the motor under test is inserted into the large end connecting sleeve, the reverse non-load principle of the one-way bearing is utilized. By measuring the magnitude of the current, it can be determined whether the motor is in the reverse direction.

[0008] Using this technology, the testing device is compact and portable, the measurement process is simple, the error tolerance is very low, the maintenance cost is low, the equipment investment cost can be saved, the production efficiency of micro motors can be improved, and the cost advantage of the enterprise's products in the market can be enhanced.

[0009] Furthermore, the coupling is provided with a large end connecting sleeve at the top and a small end connecting plate at the bottom. A one-way bearing is provided inside the coupling. The output shaft of the motor under test is fixedly connected to the inner wall of the large end connecting sleeve, and the fan blade connecting shaft is fixedly connected to the outer wall of the small end connecting plate.

[0010] In the above scheme, the coupling is mainly divided into a large end connecting sleeve, a one-way bearing, and a small end connecting plate. The large end connecting sleeve and the small end connecting plate are connected to the output shaft of the motor under test and the fan blade connecting shaft, respectively, so that the motor under test can control the rotation of the load fan blade.

[0011] Furthermore, motor leads are fixedly connected to the outer wall of the motor under test at equal intervals.

[0012] Furthermore, a data acquisition plate is provided at the bottom of one side of the outer wall of the control box, and one end of the motor lead wire is fixedly connected to the outer wall of the data acquisition plate.

[0013] In the above scheme, after the motor leads are connected to the acquisition board, the output current of the motor under test will be transmitted to the acquisition board through the motor leads, and the current signal will be collected by the acquisition board.

[0014] Furthermore, a human-machine interface is provided on one side of the outer wall of the control box, and adjacent USB ports are provided on the side of the outer wall of the control box located on the side of the human-machine interface.

[0015] In the above scheme, the data measured by the acquisition board and the result of the turn determination are sent to the human-machine interface for display via serial port, and the USB interface can be used to connect other powered devices.

[0016] Furthermore, a switch is installed on the outer wall of the top of the machine body on one side of the motor support plate.

[0017] In the above scheme, the switches adopt a separate control method, with each switch responsible for measuring one motor under test, making the measurement results more specific.

[0018] Furthermore, heat dissipation mesh is provided at the connection points of the outer walls on both sides of the main body and the control box.

[0019] In the above scheme, the heat dissipation mesh is used for ventilation and heat dissipation, increasing the heat dissipation effect of the machine body and control box.

[0020] Furthermore, the outer wall of the motor base is provided with equidistantly distributed positioning sleeves, and the positioning sleeves are slidably connected to the inner wall of the motor support plate.

[0021] In the above scheme, before the motor under test is placed in the motor tray, the three positioning sleeves need to be aligned with the positioning slots of the motor tray to increase the accuracy of subsequent measurements.

[0022] The beneficial effects of this utility model are:

[0023] This utility model proposes a micro motor steering measurement device, which adopts a measurement method of embedding a one-way bearing into a coupling. The coupling is then fixed on the fan blade connecting shaft of the load fan blade. After the output shaft of the motor under test is inserted into the large end connecting sleeve, the reverse non-load principle of the one-way bearing is utilized to determine whether the motor is in the wrong direction by measuring the magnitude of the current.

[0024] Using this technology, the testing device is compact and portable, the measurement process is simple, the error tolerance is very low, the maintenance cost is low, the equipment investment cost can be saved, the production efficiency of micro motors can be improved, and the cost advantage of the enterprise's products in the market can be enhanced.

[0031] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0032] Please refer to Figures 1-4 This utility model proposes a micro motor steering measurement device, including a body 1. A control box 2 is provided on one side of the top of the body 1, and motor support plates 3 are fixedly connected to the outer wall of the top of the body 1 by screws. A measuring component 4 is provided inside the motor support plate 3. The measuring component 4 includes a motor base 5 placed on the inner wall of the motor support plate 3, a motor under test 6 fixedly connected to the outer wall of the motor base 5, a coupling installed on the output shaft of the motor under test 6, a fan blade connecting shaft 10 installed on the bottom outer wall of the coupling, and a load fan blade 11 welded to the bottom outer wall of the fan blade connecting shaft 10.

[0033] In this embodiment, a measurement method using a one-way bearing 8 embedded in a coupling is adopted. The coupling is then fixed on the fan blade connecting shaft 10 of the load fan blade 11. After the output shaft of the motor under test 6 is inserted into the large end connecting sleeve 7, the reverse non-load principle of the one-way bearing 8 is utilized to determine whether the motor is in the reverse direction by measuring the magnitude of the current.

[0034] Using this technology, the testing device is compact and portable, the measurement process is simple, the error tolerance is very low, the maintenance cost is low, the equipment investment cost can be saved, the production efficiency of micro motors can be improved, and the cost advantage of the enterprise's products in the market can be enhanced.

[0035] The coupling has a large-end connecting sleeve 7 at the top and a small-end connecting plate 9 at the bottom. A one-way bearing 8 is installed inside the coupling. The output shaft of the motor under test 6 is fixedly connected to the inner wall of the large-end connecting sleeve 7, and the fan blade connecting shaft 10 is fixedly connected to the outer wall of the small-end connecting plate 9. The coupling mainly consists of the large-end connecting sleeve 7, the one-way bearing 8, and the small-end connecting plate 9. The large-end connecting sleeve 7 and the small-end connecting plate 9 are respectively connected to the output shaft of the motor under test 6 and the fan blade connecting shaft 10, enabling the motor under test 6 to control the rotation of the load fan blade 11.

[0036] Motor leads 12, evenly spaced, are fixedly connected to the outer wall of the motor under test 6. A data acquisition board 13 is installed at the bottom of one side of the outer wall of the control box 2, and one end of the motor lead 12 is fixedly connected to the outer wall of the data acquisition board 13. After the motor lead 12 is connected to the data acquisition board 13, the output current of the motor under test 6 is transmitted to the data acquisition board 13 through the motor lead 12, and the data acquisition board 13 collects the current signal.

[0037] A human-machine interface 14 is provided on one side of the outer wall of the control box 2, and adjacent USB interfaces 15 are provided on the side of the outer wall of the control box 2 located on the side of the human-machine interface 14. The data measured by the acquisition board 13 and the turning result are sent to the human-machine interface 14 for display via serial port. The USB interfaces 15 can be connected to other powered devices.

[0038] A switch 16 is installed on the top outer wall of the machine body 1, on one side of the motor support plate 3. The switch 16 adopts a separate control method, with each switch 16 responsible for measuring one motor 6 under test, making the measurement results more specific.

[0039] Heat dissipation mesh 17 is provided at the connection between the outer walls of both sides of the main body 1 and the control box 2. The heat dissipation mesh 17 is used for ventilation and heat dissipation, thereby increasing the heat dissipation effect of the main body 1 and the control box 2.

[0040] The outer wall of the motor base 5 is provided with equidistantly distributed positioning sleeves 18, and the positioning sleeves 18 are slidably connected to the inner wall of the motor support plate 3. Before the motor 6 to be tested is placed in the motor support plate 3, the three positioning sleeves 18 need to be aligned with the positioning grooves of the motor support plate 3 to increase the accuracy of subsequent measurements.

[0041] When using this device, first embed the one-way bearing 8 into the coupling and tighten it with glue or screws. Then, fix the small end connecting plate 9 below the one-way shaft to the outer wall of the fan blade connecting shaft 10, and tighten it with glue or screws as well. Then, place the motor under test 6 into the motor tray 3 of the test machine and position it with the three positioning sleeves 18 so that the output shaft of the motor under test 6 is inserted into the large end connecting sleeve 7 at the top of the one-way bearing 8. After preparation, start the motor under test 6. The acquisition board 13 on the control box 2 measures the current through the motor lead 12 of the motor under test 6. Since the one-way bearing 8 has the principle of no load when the motor reverses, the acquisition board 13 can determine whether it is under load based on the current. If the current is small, it is determined that the motor under test 6 is rotating in the wrong direction. Then, the measurement data and the result of the direction determination are sent to the human-machine interface 14 for display via serial port.

[0042] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
