Description
Technical Field
[0001] This utility model relates to the field of mounting base technology, and in particular to a mounting base for a three-phase asynchronous motor. Background Technology
[0002] Three-phase asynchronous motors are a type of motor that is powered by a 380V three-phase AC power supply (with a phase difference of 120 degrees). Because the rotor and stator rotating magnetic fields of a three-phase asynchronous motor rotate in the same direction but at different speeds, there is a slip rate, hence the name three-phase asynchronous motor. After the production of a three-phase asynchronous motor is completed, a fixed test is usually required. The three-phase asynchronous motor is usually fixed on a mounting base to measure parameters such as load current, speed, vibration, and noise.
[0003] However, it is worth considering that the mounting hole positions on three-phase asynchronous motors of different specifications are different, requiring different specifications of mounting bases to be used depending on the three-phase asynchronous motor. This results in a wide variety of mounting bases, increasing mold development and inventory costs, and presenting certain limitations.
[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention
[0005] In view of this, the purpose of this utility model is to provide a mounting base for a three-phase asynchronous motor, so as to solve the problem of needing to replace different specifications of mounting bases according to different three-phase asynchronous motors.
[0006] To achieve the above objectives, this utility model provides a mounting base for a three-phase asynchronous motor, including a mounting frame comprising:
[0007] At least four adjusting blocks are slidably mounted on the mounting bracket in the horizontal direction. Bolts pass through the adjusting blocks, and the connection between the adjusting blocks and the bolts is a threaded connection. The bolts are used to connect with the mounting holes on the three-phase asynchronous motor.
[0008] The pressing structure, located on the mounting bracket, applies upward pressure to the adjusting block and prevents the bolt from rotating.
[0009] Optionally, the mounting bracket is provided with two sliding seats, each with a plurality of first sliding grooves. The two sides of the adjusting block are fixedly connected to first sliders located in the first sliding grooves. The mounting bracket is provided with a plurality of second sliding grooves, each with a second slider located in the second sliding grooves fixedly connected to the two sides of the sliding seats.
[0010] Optionally, an avoidance hole is provided at the top of the inner wall of the first slide groove, which is used for the first slider to slide out of the first slide groove.
[0011] Optionally, the pressing structure includes an iron plate disposed below the mounting frame, an adjustment unit disposed on the mounting frame for adjusting the height of the iron plate, a support mechanism disposed below the iron plate for supporting the mounting frame, and a plug-in unit disposed below the adjustment block for preventing the bolt from rotating. The bottom of the adjustment block is fixedly connected with several support columns that contact the top of the iron plate.
[0012] Optionally, the plug-in unit includes a magnet block disposed below the adjusting block, a slot opened at the bottom of the bolt, and a plug block slidably disposed in the slot. The bottom of the plug block and the top of the magnet block are fixedly connected, and a guide component adapted to the magnet block is installed on the adjusting block.
[0013] Optionally, the guide includes at least two guide posts fixedly installed at the bottom of the adjusting block and a guide sleeve slidably sleeved outside the guide posts, and the guide sleeve and the magnet block are fixedly connected.
[0014] Optionally, the adjustment unit includes several lead screws fixedly installed on the top of the iron plate. The lead screws pass through the mounting frame, and a nut located above the mounting frame is sleeved on the outside of the lead screws. The connection between the lead screws and the nut is a threaded connection.
[0015] Optionally, the top of the mounting bracket is provided with two positioning plates, each with several positioning holes, and the nuts are located in the corresponding positioning holes.
[0016] Optionally, the support mechanism includes a base plate disposed below the iron plate, a plurality of prisms disposed above the base plate, and a mounting sleeve slidably sleeved on the outside of the prisms. The mounting sleeve is fixedly connected to the base plate, the prisms are fixedly connected to the mounting frame, an insert plate passes through the mounting sleeve, the prisms are provided with insertion holes adapted to the insert plates, and the insert plates pass through the corresponding insertion holes. The mounting sleeve is provided with a positioning element for positioning the position of the insert plates.
[0017] Optionally, the positioning element includes a movable ring that is slidably sleeved outside the mounting sleeve, two limiting posts that are fixedly installed at the bottom of the movable ring, and two limiting holes opened on the insert plate, with the limiting posts passing through the corresponding limiting holes.
[0018] The beneficial effects of this utility model are as follows: Based on the position of the mounting holes on the three-phase asynchronous motor, the operator drives the adjusting block to move horizontally relative to the mounting bracket. The operator then drives the bolt to pass through the corresponding mounting holes on the three-phase asynchronous motor and through the corresponding adjusting block. By rotating the bolt, the three-phase asynchronous motor is fixedly mounted on the adjusting block. The pressing structure applies upward pressure to the adjusting block and prevents the bolt from rotating, thus fixing the adjusting block relative to the mounting bracket. This avoids the bolt rotating relative to the adjusting block due to non-human factors, eliminates the need for repeated replacement of the mounting base, improves the applicability of the mounting base, and reduces mold development and inventory costs.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.
[0029] Example 1, by Figure 1 , Figure 2 and Figure 4 As shown, this utility model includes a mounting bracket 1, comprising:
[0030] At least four adjusting blocks 2 are slidably mounted on the mounting bracket 1 in the horizontal direction. Bolts 3 pass through the adjusting blocks 2, and the connection between the adjusting blocks 2 and the bolts 3 is a threaded connection. The bolts 3 are used to pass through the mounting holes on the three-phase asynchronous motor 29.
[0031] The pressing structure, mounted on the mounting bracket 1, applies upward pressure to the adjusting block 2 and prevents the bolt 3 from rotating. Based on the position of the mounting holes on the three-phase asynchronous motor 29, the operator drives the adjusting block 2 to move horizontally relative to the mounting bracket 1. The operator then drives the bolt 3 through the corresponding mounting holes on the three-phase asynchronous motor 29 and through the corresponding adjusting block 2. By rotating the bolt 3, the three-phase asynchronous motor 29 is fixedly mounted to the adjusting block 2. The pressing structure, by applying upward pressure to the adjusting block 2 and preventing the bolt 3 from rotating, fixes the adjusting block 2 relative to the mounting bracket 1. This prevents the bolt 3 from rotating relative to the adjusting block 2 due to non-human factors, eliminating the need for repeated replacement of the mounting base, increasing the applicability of the mounting base, and reducing mold development and inventory costs.
[0032] Example 2, based on Example 1, is... Figure 3 and Figure 4 As shown, the mounting bracket 1 is provided with two sliding seats 6, and the sliding seats 6 are provided with a plurality of first sliding grooves 7. The two sides of the adjusting block 2 are fixedly connected to the first sliders 8 located in the first sliding grooves 7. The mounting bracket 1 is provided with a plurality of second sliding grooves 9, and the two sides of the sliding seats 6 are fixedly connected to the second sliders 10 located in the second sliding grooves 9. The top of the inner wall of the first sliding groove 7 is provided with a clearance hole 11, which is used for the first slider 8 to slide out from the first sliding groove 7.
[0033] The operator drives the adjusting block 2 to slide relative to the sliding seat 6, so that the first slider 8 slides in the first slide groove 7. The operator also drives the sliding seat 6 to slide relative to the mounting bracket 1, so that the sliding seat 6 drives the second slider 10 to slide in the second slide groove 9. This allows the adjusting block 2 to slide horizontally relative to the mounting bracket 1. The operator then drives the adjusting block 2 to move so that the first slider 8 moves to below the corresponding clearance hole 11. Finally, the operator drives the adjusting block 2 to move upward so that the first slider 8 slides out of the first slide groove 7 through the clearance hole 11, allowing the adjusting block 2 to be replaced.
[0034] Example 3, based on Example 1, is... Figure 2 , Figure 3 and Figure 5The pressing structure includes an iron plate 4 located below the mounting bracket 1, an adjustment unit on the mounting bracket 1 for adjusting the height of the iron plate 4, a support mechanism located below the iron plate 4 for supporting the mounting bracket 1, and a plug-in unit located below the adjustment block 2 for preventing the bolt 3 from rotating. The bottom of the adjustment block 2 is fixedly connected to several support columns 5 that contact the top of the iron plate 4. The plug-in unit includes a magnet 12 located below the adjustment block 2, a slot 14 opened at the bottom of the bolt 3, and a plug 13 slidably disposed within the slot 14. The bottom of the plug 13 is fixedly connected to the top of the magnet 12. A connector for the magnet 12 is mounted on the adjustment block 2. The guide is adapted to 12 phases. The guide includes at least two guide posts 15 fixedly installed at the bottom of the adjustment block 2 and a guide sleeve 16 slidably sleeved on the outside of the guide posts 15. The guide sleeve 16 and the magnet block 12 are fixedly connected. The adjustment unit includes several lead screws 17 fixedly installed on the top of the iron plate 4. The lead screws 17 pass through the mounting frame 1. The outside of the lead screws 17 is sleeved with nuts 18 located above the mounting frame 1. The lead screws 17 and nuts 18 are connected by threads. The top of the mounting frame 1 is in contact with two positioning plates 19. Several positioning holes 20 are opened on the positioning plates 19, and the nuts 18 are located in the corresponding positioning holes 20.
[0035] When bolt 3 penetrates adjusting block 2, magnet 12 is magnetically attracted to iron plate 4, and the operator drives nut 18 to rotate, so that nut 18 drives screw 17 and iron plate 4 to move upward. Iron plate 4 drives magnet 12 and insert block 13 to move upward. Magnet 12 drives guide sleeve 16 to slide relative to guide post 15. Through the design of guide sleeve 16 and guide post 15, magnet 12 moves smoothly in the vertical direction. Finally, magnet 12 drives the top of insert block 13 to insert into slot 14, and the top of iron plate 4 and the bottom of support post 5 come into contact. Iron plate 4 applies upward pressure to support post 5 and adjusting block 2, so that adjusting block 2 is fixed relative to mounting bracket 1. Insert block 13 limits the position of bolt 3 to prevent bolt 3 from rotating relative to adjusting block 2 due to non-human factors. The operator drives positioning plate 19 to be placed on mounting bracket 1, and nut 18 is located in the corresponding positioning hole 20. Through the cooperation of positioning hole 20 and positioning plate 19, nut 18 is prevented from rotating relative to screw 17 due to non-human factors.
[0036] Example 4, based on Example 3, by Figure 1 , Figure 2 and Figure 6The support mechanism includes a base plate 21 located below the iron plate 4, several prisms 22 located above the base plate 21, and a mounting sleeve 23 slidably sleeved on the outside of the prisms 22. The mounting sleeve 23 is fixedly connected to the base plate 21, and the prisms 22 are fixedly connected to the mounting bracket 1. An insert plate 24 passes through the mounting sleeve 23. The prisms 22 have insertion holes 26 that are adapted to the insert plate 24, and the insert plate 24 passes through the corresponding insertion holes 26. The mounting sleeve 23 is provided with positioning components for positioning the insert plate 24. The positioning components include a movable ring 25 slidably sleeved on the outside of the mounting sleeve 23, two limiting posts 27 fixedly installed at the bottom of the movable ring 25, and two limiting holes 28 opened on the insert plate 24, and the limiting posts 27 pass through the corresponding limiting holes 28.
[0037] The mounting bracket 1 is supported by the base plate 21. The operator fixes the base plate 21 in the preset position. The operator drives the movable ring 25 to move upward so that the limiting post 27 disengages from the corresponding limiting hole 28, thereby releasing the restriction on the position of the insert plate 24. The operator drives the insert plate 24 to disengage from the mounting sleeve 23 and the insertion hole 26, thereby releasing the restriction on the position of the prism 22. The operator drives the mounting bracket 1 to move upward so that the prism 22 disengages from the mounting sleeve 23, thereby completing the removal of the mounting bracket 1, which facilitates the replacement and maintenance of other components on the mounting bracket 1.
