Description

Technical Field

[0001] This utility model relates to the field of motor quality inspection technology, and in particular to a motor quality inspection device. Background Technology

[0002] A motor vibration tester is a specialized instrument used to detect and analyze the vibration of motors during operation. It provides data support for judging the motor's operating status, potential faults, and performance, and plays an important role in motor manufacturing, installation, and maintenance.

[0003] When using a motor vibration tester to inspect a motor, the probe of the tester needs to be placed against the test area of ​​the motor to capture physical quantity signals such as vibration displacement, velocity, or acceleration generated during motor operation. However, the probe is usually connected to the vibration tester through a threaded connector on the tester. At the same time, the probe can easily transmit the motor's vibration to the tester body. Continuous vibration may cause the connection between the probe and the tester body to loosen, which will reduce the measurement accuracy of the motor vibration tester. Summary of the Invention

[0004] This invention provides a motor quality inspection device to address the problem that the probe transmits motor vibrations to the tester body, and continuous vibration may cause the connection between the probe and the tester body to loosen, thereby reducing the measurement accuracy of the motor vibration tester.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a motor quality inspection device, comprising a motor vibration tester body, a threaded connector installed at one end of the motor vibration tester body, a probe threadedly connected to the outer surface of the threaded connector, an auxiliary device provided between the probe and the motor vibration tester body, the auxiliary device providing auxiliary fixation between the probe and the threaded connector by setting an airbag capable of adjusting the degree of deformation on the outer surface of the probe and the threaded connector.

[0006] The effect achieved by the above components is as follows: by adjusting the degree of deformation of the airbag, the outer surface of the rubber airbag abuts against the outer surface of the probe and the threaded connector. The friction between the rubber airbag and the outer surface of the probe and the threaded connector can help fix the probe and the threaded connector, which helps to prevent the connection between the probe and the tester body from becoming loose, thereby improving the measurement accuracy of the motor vibration tester.

[0007] Preferably, the auxiliary device includes an air chamber, on one side of the motor vibration tester body is fixedly installed in the air chamber, the threaded connector is disposed inside the air chamber, an air bag is fixedly installed on one side of the air chamber, the air bag is made of rubber, the air bag is connected to the inner wall of the air chamber, a connecting cylinder is fixedly installed on the outer surface of the air bag, an air cylinder is fixedly installed at one end of the connecting cylinder, and one end of both the connecting cylinder and the air cylinder is fixedly installed on one side of the motor vibration tester body.

[0008] The effect achieved by the above components is as follows: pushing the piston causes it to move on the inner wall of the air cylinder. The piston compresses the air inside the air cylinder, causing the air in the air cylinder to enter the air bag through the connecting cylinder and the air chamber, causing the air bag to inflate until the outer surface of the air bag is completely in contact with the outer surface of the probe and the threaded connector. Then the rubber air bag can provide auxiliary fixation between the threaded connector and the probe.

[0009] Preferably, a plurality of protrusions are evenly distributed on the inner side of the outer surface of the airbag.

[0010] The effect achieved by the above components is that by uniformly setting protrusions on the outer surface of the airbag, the friction between the airbag and the probe and the threaded connector can be increased, making the connection between the rubber airbag and the probe and the threaded connector more stable.

[0011] Preferably, an L-shaped cylinder is fixedly installed at the edge of the top of the air chamber, and the airbag is disposed inside the L-shaped cylinder.

[0012] The effect achieved by the above components is as follows: by setting the L-shaped cylinder, the L-shaped cylinder can limit the airbag, making it easier for the airbag to deform towards the outer surface of the probe and threaded connector when it is compressed by the air inside, and making it easier to quickly adjust the airbag.

[0013] Preferably, the piston has a threaded rod threadedly connected to its inner wall, and one end of the threaded rod is rotatably mounted on one side of the inner wall of the cylinder.

[0014] The effect achieved by the above components is as follows: rotating the threaded rod will cause the piston to move on the inner wall of the cylinder. At the same time, when the threaded rod stops rotating, it can also fix the piston, which is convenient for adjusting the piston through the threaded rod.

[0015] Preferably, a ring is fixedly installed on the top of the inner wall of the air cylinder, the piston is disposed on one side of the ring, and the threaded rod is disposed inside the ring.

[0016] The effect achieved by the above components is that by setting up a ring, the ring can block one end of the air cylinder, which helps to prevent the piston from dislodging from the inner wall of the air cylinder when adjusting the piston.

[0017] Preferably, an operating block is fixedly installed at one end of the threaded rod, and the outer surface of the operating block is provided with protrusions.

[0018] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0019] Preferably, a retaining strip is fixedly installed on the inner wall of the air cylinder, and the piston is slidably installed on the outer surface of the retaining strip.

[0020] The effect achieved by the above components is that by setting the retaining strip, the piston can be limited and guided, making the threaded rod more stable when driving the piston to move.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by adjusting the degree of deformation of the airbag, the outer surface of the rubber airbag abuts against the outer surface of the probe and the threaded connector. The friction between the rubber airbag and the outer surface of the probe and the threaded connector can help fix the probe and the threaded connector, which helps to prevent the connection between the probe and the tester body from becoming loose, thereby improving the measurement accuracy of the motor vibration tester.

[0024] Example 1, referring to Figures 1-3As shown, this embodiment discloses a motor quality inspection device, including a motor vibration tester body 1. A threaded connector 2 is installed at one end of the motor vibration tester body 1, and a probe 3 is threadedly connected to the outer surface of the threaded connector 2. (The model of the motor vibration tester body 1 can be SKF Microlog.) 75, the probe 3 used in this test is generally model CMXA75). An auxiliary device 4 is provided between the probe 3 and the main body 1 of the motor vibration tester. The auxiliary device 4 uses an air bladder 42, which can adjust the degree of deformation, to provide auxiliary fixation between the probe 3 and the threaded connector 2. By setting the air bladder 42, since the degree of deformation of the air bladder 42 is adjustable, after the probe 3 is installed, the degree of deformation of the air bladder 42 can be adjusted so that the outer surface of the rubber air bladder 42 abuts against the outer surface of the probe 3 and the threaded connector 2. The friction between the rubber air bladder 42 and the outer surface of the probe 3 and the threaded connector 2 can provide auxiliary fixation between the probe 3 and the threaded connector 2, which helps to prevent the connection between the probe 3 and the tester body from becoming loose, thereby improving the measurement accuracy of the motor vibration tester.

[0025] Reference Figures 2-4 As shown, the auxiliary device 4 includes an air chamber 41, on one side of which the motor vibration tester body 1 is fixedly mounted. A threaded connector 2 is disposed inside the air chamber 41. An air bag 42, made of rubber, is fixedly mounted on one side of the air chamber 41. The air bag 42 is connected to the inner wall of the air chamber 41. A connecting cylinder 43 is fixedly mounted on the outer surface of the air bag 42. An air cylinder 44 is fixedly mounted on one end of the connecting cylinder 43. Both ends of the connecting cylinder 43 and the air cylinder 44 are fixedly mounted on one side of the motor vibration tester body 1. Pushing the piston 45 causes it to move within the inner wall of the air cylinder 44, thus impacting the interior of the air cylinder 44. The air is compressed, causing the air in the air cylinder 44 to enter the air bag 42 through the connecting cylinder 43 and the air chamber 41, causing the air bag 42 to inflate until the outer surface of the air bag 42 is completely in contact with the outer surfaces of the probe 3 and the threaded connector 2. The rubber air bag 42 can then provide auxiliary fixation between the threaded connector 2 and the probe 3. Several protrusions are evenly arranged on the inner side of the outer surface of the air bag 42. By evenly arranging the protrusions on the outer surface of the air bag 42, the friction between the air bag 42, the probe, and the threaded connector 2 can be increased, making the connection between the rubber air bag 42 and the probe and the threaded connector 2 more stable.

[0026] Reference Figures 2-4As shown, an L-shaped cylinder 47 is fixedly installed at the top edge of the air chamber 41. The air bladder 42 is located inside the L-shaped cylinder 47. By setting the L-shaped cylinder 47, the L-shaped cylinder 47 can limit the air bladder 42, making it easier for the air bladder 42 to deform towards the outer surface of the probe 3 and the threaded connector 2 when compressed by the air inside it, making it easier to quickly adjust the air bladder 42. A threaded rod 46 is threadedly connected to the inner wall of the piston 45. One end of the threaded rod 46 is rotatably installed on one side of the inner wall of the air cylinder 44. Rotating the threaded rod 46 will drive the piston 45 to move on the inner wall of the air cylinder 44. At the same time, when the threaded rod 46 stops rotating, it can also fix the piston 45, which is beneficial to adjust the piston 45 through the threaded rod 46.

[0027] Reference Figure 2 and Figure 3 As shown, a ring 48 is fixedly installed on the top of the inner wall of the air cylinder 44. A piston 45 is located on one side of the ring 48, and a threaded rod 46 is located inside the ring 48. By setting the ring 48, the ring 48 can block one end of the air cylinder 44, which helps to prevent the piston 45 from disengaging from the inner wall of the air cylinder 44 when adjusting the piston 45. An operating block 49 is fixedly installed on one end of the threaded rod 46. The outer surface of the operating block 49 is provided with protrusions. By setting the operating block 49, rotating the operating block 49 can drive the threaded rod 46 to rotate. At the same time, the protrusions on the outer surface of the operating block 49 can effectively increase the friction of the outer surface of the operating block 49, which has an anti-slip effect when rotating the operating block 49.

[0028] Reference Figure 2 and Figure 3 As shown, a retaining strip 410 is fixedly installed on the inner wall of the air cylinder 44, and the piston 45 is slidably installed on the outer surface of the retaining strip 410. By setting the retaining strip 410, the piston 45 can be limited and guided, making the threaded rod 46 more stable when driving the piston 45 to move.

[0029] Working principle: Rotating the operating block 49 drives the threaded rod 46 to rotate. Under the limit of the locking strip 410, the threaded rod 46 drives the piston 45 to slide on the inner wall of the air cylinder 44. The piston 45 compresses the air inside the air cylinder 44, causing the air in the air cylinder 44 to enter the air bag 42 through the connecting cylinder 43 and the air chamber 41, causing the air bag 42 to inflate. Due to the limit of the L-shaped cylinder 47, the air bag 42 will gradually deform towards the outer surface of the threaded connector 2 and the probe 3 until the protruding outer surface of the air bag 42 completely abuts against the outer surface of the probe 3 and the threaded connector 2. Then, the rubber air bag 42 can provide auxiliary fixation between the threaded connector 2 and the probe 3, which helps to prevent the connection between the probe 3 and the tester body from becoming loose. At the same time, when the operating block 49 is stopped, the threaded rod 46 can also fix the piston 45, thereby fixing the degree of deformation of the air bag 42 and preventing the fixation of the rubber air bag 42 from becoming loose.
