Detailed Implementation

[0018] 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.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 This utility model provides a technical solution: a high-speed experimental test bench, including a drive integrated device 1, a test integrated device 2, and a control box 3.

[0020] The control box 3 contains a power supply device to provide power to the entire test bench. Both the drive integration device 1 and the test integration device 2 are electrically connected to the power supply device within the control box 3, ensuring the normal operation of each component. The top surface of the control box 3 connects to the drive integration device 1 and the test integration device 2, providing support and fixation.

[0021] The drive integration device 1 includes a variable frequency water-cooled motor 11, a motor connecting seat 12, a drive integration base plate 13, two hinged bearing seats 14, and a connecting shaft 15. The top surface of the drive integration base plate 13 is connected to the motor connecting seat 12 and the two hinged bearing seats 14. The variable frequency water-cooled motor 11 is housed within the motor connecting seat 12. The drive end of the variable frequency water-cooled motor 11 is connected to one end of the connecting shaft 15 via a coupling. The connecting shaft 15 is rotatably connected within the hinged bearing seats 14. The variable frequency water-cooled motor 11 provides stable power output. The hinged bearing seats 14 facilitate the installation and removal of the connecting shaft 15. Simultaneously, the variable frequency water-cooled motor 11 is externally fitted with a first dustproof box 4, and the connecting shaft 15 is externally fitted with a second dustproof box 5, effectively preventing dust and other impurities from entering, ensuring normal operation of the equipment and extending its service life. The drive end of the drive integration device 1 extends into the inner cavity of the test integration device 2, providing power for the testing process.

[0022] The connecting shaft 15 is used to mount a dynamic balancing rotor disk to ensure test balance. Depending on the different testing requirements of the test piece, the connecting shaft 15 can be flexibly disassembled through the design of the hinged bearing housing 14. Furthermore, the hinged bearing housing 14... Figure 5 As shown, the hinged bearing housing 14 adopts a snap-fit ​​design and is quickly assembled and disassembled through a snap-fit ​​connection.

[0023] The test integration device 2 includes a housing 21 and a quick-connect integration device 26. The quick-connect integration device 26 for inserting the test component fixture is connected to the inner wall of the housing 21.

[0024] The quick-connect integration device 26 includes a slide base 261, a slide table 262, a connector 263, a limiting plate 264, and a limiting block 265. The slide base 261 is connected to the inner wall of the housing 21. The slide table 262 is slidably connected to the slide base 261, allowing the slide table 262 to slide freely on the slide base 261, thereby adjusting the position of the connector 263. The outer wall of the slide table 262 is connected to the connector 263 for inserting test fixtures. Test fixtures of different shapes and sizes can be easily inserted into the connector 263. The side wall of the slide table 262 is connected to the limiting plate 264. The side wall of the housing 21 has an elongated through hole, and the limiting block 265 is slidably connected within the elongated through hole of the housing 21. The limiting block 265 is connected to the limiting plate 264 by bolts. Once the slide 262 is adjusted to the appropriate position, the bolts are tightened to make the limiting block 265 and the limiting plate 264 tightly connected, thereby fixing the position of the slide 262 and ensuring the stability of the test piece during the testing process.

[0025] The top and bottom surfaces of the limiting block 265 are respectively connected to baffles. The baffles are slidably connected in the interlayer of the side wall of the box 21. The baffles are used to prevent a large amount of external dust from entering and can also play a certain role in heat preservation, so as to avoid inaccurate test results caused by inaccurate temperature inside the box 21.

[0026] In addition, the test integration device 2 also includes a heating device 22, a temperature sensor 23, and two electromagnets 24 disposed on the same side wall of the inner cavity of the housing 21. The two electromagnets 24 are arranged opposite each other, and a through hole 211 is provided on the side wall of the inner cavity of the housing 21 between the two electromagnets. The driving end of the drive integration device 1 passes through the through hole 211 and enters the inner cavity of the housing 21. One end of the heating device 22 and one end of the temperature sensor 23 are both disposed in the inner cavity of the housing 21 for heating and temperature monitoring of the environment inside the housing 21; the other end of the heating device 22 and the other end of the temperature sensor 23 extend out of the housing 21 and are electrically connected to the power supply device in the control box 3 to realize the control of the heating and temperature sensing functions. The top surface of the housing 21 is connected to a cover, and the housing 21 is connected to the cover by a quick-connect buckle 25, which facilitates the opening and closing of the cover and the installation and removal of the test piece.

[0027] The two electromagnets 24 are used for non-contact fixing. This fixing method is suitable for high-speed testing scenarios. The two electromagnets 24 generate a strong magnetic field to attract ferromagnetic materials (such as silicon steel sheets or magnets) on the rotor surface, achieving fixing without mechanical contact. This avoids interference with the rotor's dynamic balance caused by traditional clamps, and is especially suitable for high-speed rotation testing (such as speeds > 10,000 rpm); it also reduces mechanical stress concentration and prevents rotor deformation due to clamp pressure at high speeds. This structure is prior art and will not be described in detail here.

[0028] Working principle: Test Component Installation: Based on the shape and size of the test component, select a suitable test component fixture and insert it into the insertion platform 263 of the quick-connect integration device 26. Adjust the position of the test component by sliding the slide 262 to ensure it is in a suitable testing position. Then, tighten the bolts between the limiting block 265 and the limiting plate 264 to fix the position of the slide 262, ensuring the test component will not move during testing.

[0029] Test Procedure: The power supply in the control box 3 is turned on, and the variable frequency water-cooled motor 11 is started. The drive end of the drive integrated device 1 passes through the through hole 211 and enters the inner cavity of the test integrated device 2 to provide power to the test component. If a specific ambient temperature needs to be simulated, the heating device 22 can be used to heat the inside of the chamber 21, and the temperature inside the chamber 21 can be monitored in real time by the temperature sensor 23 to keep the temperature within the set range. At the same time, the two electromagnets 24 can generate corresponding magnetic fields according to the test component being a motor rotor, thus magnetically fixing the test component. During the test, various performance data of the test component are recorded by relevant data acquisition equipment.

[0030] Test Completion: After the test is completed, turn off the power supply in the control box 3 to stop the operation of the variable frequency water-cooled motor 11, the heating device 22, and other equipment. Loosen the bolts between the limit block 265 and the limit plate 264, slide the slide table 262, and remove the test piece from the insertion table 263 to complete one test cycle.
