Description
Technical Field
[0001] This utility model relates to the field of motor testing technology, and more specifically, to a testing device for electromechanical equipment. Background Technology
[0002] Electric motors are widely used in various industries and are one of the essential electromechanical devices for achieving mechanization. Electric motors undergo multiple tests before leaving the factory, such as surface appearance inspection, noise testing, and operational testing. During operational testing, the axial and radial runout of the motor shaft needs to be measured. For example, general standards require that the axial runout of the motor shaft be less than 0.2 mm and the radial runout be less than 0.05 mm to ensure normal operation and long-term stability of the motor.
[0003] As motors are used for a long time, the internal components will wear out, which will increase the radial runout of the motor shaft. The range of radial runout is difficult to determine by visual observation alone, and directly disassembling the motor for testing will have a significant impact. Therefore, it is necessary to design a device that can easily detect whether the motor can continue to be used. Utility Model Content

[0026] This utility model discloses an electromechanical equipment testing device. A support frame supports a fixed component, and adjusting the position of the fixed component allows the support frame to be positioned directly above the motor under test. A snap-fit component abuts against the output shaft of the motor under test. The initial contact pressure between the snap-fit component and the detection sensor is adjusted. Then, power is supplied to the motor under test via a power supply and a connecting component, driving the motor shaft to rotate at a predetermined voltage. Simultaneously, the rotation of the motor shaft is converted into a detection value by the detection sensor, which is then displayed for intuitive observation. Based on the range or degree of change in the detection value, the radial runout range of the tested motor can be determined, thus deciding whether to continue using the motor.

[0044] The following embodiments will provide a detailed description of an electromechanical equipment testing device according to this application.
[0045] In this embodiment, as Figures 1 to 3 As shown, the electromechanical equipment testing device is used to test motors and includes: a support frame 1, which is hollow;
[0046] Fixing component 2 is provided at the fixing holes on both sides of the support frame 1. Fixing component 2 is located at the fixing holes on both sides of the support frame 1 and is used to abut against the motor being tested.
[0047] Power supply 3 is mounted on support frame 1;
[0048] The connecting component 4 is provided on the side of the support frame 1 with a connection window. The connecting component 4 is located in the connection window and is used to connect to the terminal of the motor to be tested.
[0049] The snap-fit component 5 is slidably mounted on the support frame 1 and is used to abut against the rotating shaft of the motor being tested.
[0050] The detection sensor 6 is disposed on the upper side of the snap-fit assembly 5 and is used to abut against the snap-fit assembly 5;
[0051] Display 7 is connected to the detection sensor 6 and is used to display the value of the detection sensor 6.
[0052] In this technical solution, the support frame 1 is C-shaped, horizontally and symmetrically arranged, and hollow, running through the front and back. The left and right sides of the support frame 1 have two strip-shaped, horizontally arranged fixing holes. Two or more sets of fixing components 2 are slidably and fixably mounted on the fixing holes on both sides. The position of the support frame 1 can be adjusted by adjusting the fixing components 2 at their positions relative to the front, back, left, right, and up / down of the motor under test. The power supply 3, consisting of a battery or battery pack, is fixed to the upper side of the support frame 1. The connection window is a rectangular window located on the right side of the support frame 1. A connecting component 4 is slidably and fixably mounted at this connection window, electrically connecting the power supply 3 and the motor under test. The operating state of the motor can be adjusted by changing the voltage and frequency of the power supply 3, facilitating the testing of different speeds.
[0053] The card-connecting component 5 includes:
[0054] The sliding component 501 is provided with a sliding groove in the support frame 1, and the sliding component 501 is slidably engaged in the sliding groove.
[0055] The abutment 502 and the sliding member 501 are provided with through holes extending vertically. The abutment 502 is slidably disposed at the through hole, and the bottom end of the abutment 502 is used to abut against the rotating shaft of the motor being tested.
[0056] The adjusting member 503 and the abutting member 502 are provided with a first threaded hole. The adjusting member 503 is provided with an external thread that matches the threaded hole. The top end of the adjusting member 503 abuts against the detection sensor 6.
[0057] In this technical solution, a long, narrow sliding groove extending in the front-to-back direction is provided in the middle of the upper side of the support frame 1. The sliding member 501 of the locking assembly 5 is slidably disposed in the sliding groove, and the abutment member 502 of the locking assembly 5 is slidably disposed on the sliding member 501 in the vertical direction. The detection sensor 6 is a pressure sensor, which is mounted on the upper side of the support frame 1 via a C-shaped support plate. The support plate has an oblong hole for the detection sensor 6 to slide back and forth, so as to facilitate the adjustment of the back-to-back position of the detection sensor 6. The detection sensor 6 is electrically connected to the display 7, which can display the pressure value detected by the detection sensor 6.
[0058] The two ends of the sliding member 501 are engaged with the two sides of the upper side of the support frame 1. The middle of the sliding member 501 is set as a plane and fits against the side of the sliding groove, so that the sliding member 501 can only slide back and forth along the sliding groove. The abutment member 502 is set as a Z-shape. The sliding member 501 has a non-circular through hole that runs vertically through it. The upper part of the abutment member 502 is set as a contour that matches the shape of the through hole. This setting can prevent the sliding member 501 and the abutment member 502 from rotating during the test.
[0059] The bottom end of the abutment 502 is spherical to facilitate contact between the abutment 502 and the motor shaft. The upper part of the abutment 502 has a first threaded hole, and the adjusting member 503 is threadedly connected to this first threaded hole. The top end of the adjusting member 503 is also spherical. In use, the sliding member 501 and the abutment 502 are adjusted to contact the motor shaft. Then, the adjusting member 503 is rotated until it contacts the detection sensor 6 and the display 7 shows a certain value. Power is then supplied to the motor via the electrical connection assembly 4 to rotate the motor shaft. The change in pressure caused by the radial runout during motor shaft rotation is observed on the display 7 to determine whether the motor can continue to be used. For example, if the detected pressure change exceeds 200N, the radial runout range of the motor shaft is considered to exceed the requirements for normal use, and the motor needs to be replaced.
