Auxiliary starting device for micro motor detection

Abstract

This utility model relates to an auxiliary starting device for testing micro motors, comprising a base plate, a support frame, and a support plate. The support frame and support plate are both vertically mounted on the base plate. A testing machine is mounted on the support frame, and a tail extension shaft is mounted on the testing machine and driven by its rotating shaft. The test motor is mounted on the support plate, and the rotating shaft of the test motor is driven by the rotating shaft of the testing machine, so that when the rotating shaft of the testing machine rotates, it drives the rotating shaft of the test motor to rotate. This auxiliary starting device for testing micro motors uses a linear module to move a rotating actuator mounted on the mounting plate, thereby connecting the rotating shaft of the rotating actuator to the tail extension shaft via a one-way bearing. In other words, the rotating actuator drives the tail extension shaft and the rotating shaft of the testing machine to rotate, thus providing auxiliary support to the test motor.

Description

Technical Field

[0001] This utility model relates to the field of micro motor testing technology, specifically an auxiliary starting device for micro motor testing. Background Technology

[0002] Miniature motor testing refers to the monitoring, testing, and evaluation of various performance characteristics and operating conditions of miniature motors. This testing is typically designed to ensure that miniature motors operate normally, meet design requirements, and can withstand their required loads and environmental conditions.

[0003] When operating a well-known online testing machine for micro motors, the starting torque of the motor is often too small to overcome the initial static torque of the testing machine. Operators need to manually assist in rotating the motor to start the testing process, which is very troublesome and unsafe. This auxiliary starting device is especially necessary for fully automatic online testing machines without operators. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary starting device for testing micro motors, which solves the problem that it is very troublesome and unsafe for operators to manually rotate the motor to start the test.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary starting device for testing a micro motor, comprising a base plate, a support frame, and a support plate;

[0006] The support frame and support plate are both vertically mounted on the base plate. A testing machine is mounted on the support frame, and a tail extension shaft is mounted on the testing machine and driven by its rotating shaft. The test motor is mounted on the support plate, and the rotating shaft of the test motor is driven by the rotating shaft of the testing machine, so that when the rotating shaft of the testing machine rotates, it can drive the rotating shaft of the test motor connected to it to rotate.

[0007] Furthermore, the front cross-section of the support frame is H-shaped, and the testing machine is installed laterally inside the support frame.

[0008] Furthermore, two through holes are provided on both the left and right sides of the support frame, which are respectively for the tail extension shaft and the rotating shaft of the testing machine to rotate.

[0009] Furthermore, the tail extension shaft and the rotating shaft of the testing machine are respectively connected to the interior of the two through holes by bearings.

[0010] Furthermore, the tail extension shaft and the rotation axis of the testing machine are located on the same horizontal line.

[0011] Furthermore, a linear module is installed on the base plate, a movable plate is drivenly connected to the linear module, and an mounting plate is assembled on the movable plate;

[0012] A rotation actuator is provided on the mounting plate, and the rotation actuator is connected to the tail extension shaft via a one-way bearing.

[0013] Furthermore, the output end of the rotary actuator is concentrically arranged with the tail extension shaft.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. The auxiliary starting device for testing the micro motor drives the rotating actuator mounted on the mounting plate to move via a linear module. This causes the rotating shaft of the rotating actuator to be connected to the tail extension shaft via a one-way bearing. In other words, the rotating actuator drives the tail extension shaft and the rotating shaft of the testing machine to rotate, thereby providing an auxiliary function for the motor under test.

[0016] 2. The auxiliary starting device for testing this micro motor utilizes the characteristic that the tail extension shaft can rotate smoothly in one direction and cannot rotate in the opposite direction within the one-way bearing hole to transmit force, thereby driving the test machine shaft to rotate and thus starting the motor under test. After the motor under test enters stable rotation, the test is performed. At this time, the linear module will disengage the one-way bearing auxiliary device, completing one work cycle.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 This embodiment provides an auxiliary starting device for testing a micro motor, which is used to assist the tested motor 6.

[0021] Specifically, it includes a base plate 11, a support frame 10, and a support plate 9; the support frame 10 and the support plate 9 are both vertically mounted on the base plate 11. A testing machine 5 is mounted on the support frame 10, and a tail extension shaft 1 is mounted on the testing machine 5 and is connected to its rotating shaft. The test motor 6 is mounted on the support plate 9, and the rotating shaft of the test motor 6 is connected to the rotating shaft of the testing machine 5.

[0022] In actual use, the rotating shaft of the test motor 6 is connected to the rotating shaft of the test machine 5. By installing the tail extension shaft 1 at the tail end of the test machine 5, the tail extension shaft 1 is driven to rotate the inside of the test machine 5, and at the same time, it plays an auxiliary starting role for the rotating shaft of the test motor 6.

[0023] It should be noted that, in order to facilitate the connection between the rotating shaft of the test motor 6 and the rotating shaft of the test machine 5, and to ensure that the tail extension shaft 1 and the rotating shaft of the test motor 6 are in a concentric position, in this embodiment, the front cross-section of the support frame 10 is preferably H-shaped, the test machine 5 is installed laterally inside the support frame 10, and two through holes are opened on both the left and right sides of the support frame 10 for the tail extension shaft 1 and the rotating shaft of the test machine 5 to rotate respectively.

[0024] Furthermore, in order to improve the stability of the tail extension shaft 1 and the test machine 5 during rotation, in this embodiment, the tail extension shaft 1 and the rotating shaft of the test machine 5 are respectively connected to the two through holes of the bearing rotation connector, and the tail extension shaft 1 and the rotating shaft of the test machine 5 are located on the same horizontal line.

[0025] Furthermore, in order to facilitate the rotation of the tail extension shaft 1 and the rotating shaft of the testing machine 5, a linear module 2 is installed on the base plate 11 in this embodiment. A moving plate 7 is connected to the linear module 2, and an mounting plate 8 is assembled on the moving plate 7. A rotation actuator 3 is provided on the mounting plate 8, and the rotation actuator 3 is connected to the tail extension shaft 1 through a one-way bearing 4.

[0026] In actual use, the linear module 2 drives the rotating actuator 3 mounted on the mounting plate 8 to move, thereby connecting the rotating shaft of the rotating actuator 3 to the tail extension shaft 1 through the one-way bearing 4. That is, the rotating actuator 3 drives the tail extension shaft 1 and the rotating shaft of the test machine 5 to rotate, thereby playing an auxiliary role in the test motor 6.

[0027] It should be noted that the tail extension shaft 1 can be made as a separate extension shaft and connected to the rear end of the test machine 5 shaft, or the tail shaft can be directly lengthened when making the test machine 5. The rotating actuator 3 can be a servo motor, pneumatic motor, pneumatic rotor, or other finished products. The one-way bearing 4 can be a finished product purchased.

[0028] In summary, the auxiliary starting device for testing this micro motor first extends the tail of the testing machine 5, and then installs a linear module 2 that can move back and forth on the testing machine 5. A rotary actuator 3 is installed on the linear module 2, and a one-way bearing 4 is installed at the head of its rotating shaft, concentric with the extended tail of the testing machine 5. When the tested motor 6 needs to be started, the linear module 2 at the rear of the testing machine 5 pushes the one-way bearing 4 installed at the head of the rotating shaft of the rotary actuator 3 into the extended tail shaft 1. The rotary actuator 3 rotates, and the extended tail shaft 1, which can rotate smoothly in one direction and is clamped and cannot rotate in the opposite direction, transmits force to drive the shaft of the testing machine 5 to rotate, thereby starting the tested motor 6. After the tested motor 6 enters stable rotation, the test is performed. At this time, the linear module 2 removes the one-way bearing 4 auxiliary device, completing one work cycle.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
