Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor installation technology, and in particular to a machine tool spindle motor mounting base. Background Technology
[0002] Machine tools, as core equipment in modern manufacturing, are widely used in many fields such as automobiles, aerospace, mold manufacturing, and machining. Their processing accuracy and efficiency directly affect product quality and production efficiency. As the power source of the machine tool, the spindle motor provides driving force for the rotational motion of the machine tool spindle. The stability and accuracy of its installation play a crucial role in the overall performance of the machine tool. The mounting base of the spindle motor is a key component connecting the spindle motor and the machine tool bed. It must not only withstand various forces generated by the spindle motor during operation, such as torque and vibration, but also ensure precise transmission and concentricity between the spindle motor and the spindle.
[0003] Existing centrifugal fans are driven by a motor that drives the fan shaft via a belt and pulley. The fan shaft and the drive motor are mounted on a support frame. The mounting bracket of the drive motor is usually fixed. Installing the belt is very laborious, and after a period of use, the belt used for transmission may deform and loosen, which requires adjusting the position of the drive motor.
[0004] Existing patent (publication number: CN212272583U) discloses a motor mounting base for a centrifugal fan, comprising: a base, a sliding base, fixing bolts, a mounting plate, a fixing ring, a threaded ring, a screw, and a hexagonal limiting block. The sliding base is strip-shaped, with two sliding bases arranged parallel to each other on the base. The mounting plate is connected to the sliding base by fixing bolts. The fixing ring is fixed to the front end of the base, and the threaded ring is fixed to the lower end face of the mounting plate. The screw passes through the fixing ring and is connected to the threaded ring by threads. The hexagonal limiting block is fixed to the top of the screw and is located outside the fixing ring. The sliding base has a C-shaped steel cross-section. The fixing head of the fixing bolt is located inside the sliding base, while the threaded section extends out of the sliding base and passes through the mounting through-hole of the mounting plate, with the top end fixed by a nut and washer. This utility model has advantages such as simple structure, convenient use, and good performance.
[0005] To address the aforementioned issues, existing patents offer solutions, but these solutions cannot flexibly adjust the position of the spindle motor after installation, making it difficult to precisely align the output shaft of the spindle motor with the machine tool spindle. Furthermore, existing mounting bases do not reinforce the output shaft of the spindle motor, making it prone to misalignment.
[0006] To address this, a machine tool spindle motor mounting base is proposed. Utility Model Content

[0012] Preferably, the leveling and fixing mechanism includes four leveling seats disposed at the bottom of the base. The leveling seats are Z-shaped, and two mounting holes are opened at the bottom of the leveling seats. An adjusting rod is threadedly connected to the middle of the leveling seat, and an adjusting plate is disposed at the bottom of the adjusting rod.
[0013] Preferably, a reinforcing nut is threaded onto one side of the adjusting screw, and the reinforcing nut and the locking nut are located on opposite sides of the fixed base.

[0028] 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.
[0029] Please see Figures 1 to 5 This utility model provides a technical solution:
[0030] A machine tool spindle motor mounting base includes a base 1, a mounting seat 2 is provided on the top of the base 1, a motor body 9 is provided on the top of the mounting seat 2, an adjustment mechanism 3 is provided between the base 1 and the mounting seat 2, and a leveling and fixing mechanism 4 is provided at the bottom of the base 1.
[0031] The adjustment mechanism 3 includes four fixed seats 31 distributed on the four sides of the base 1. Four adjusting screws 32 are fixedly connected to the four sides of the mounting seat 2. Locking nuts 33 are threadedly connected to the side walls of the adjusting screws 32. The side walls of the locking nuts 33 are in contact with the fixed seats 31. A stabilizing component 34 for stabilizing the output shaft of the motor body 9 is provided at one end of the mounting seat 2. A mounting component 35 is provided between the motor body 9 and the mounting seat 2.
[0032] Specifically, such as Figure 3 As shown, the stabilizing assembly 34 includes a stabilizing seat 341 disposed on the top of the mounting base 2, a stabilizing cover 342 bolted to the top of the stabilizing seat 341, and a bearing ring 343 disposed on the output shaft of the motor body 9, the bearing ring 343 being located between the stabilizing seat 341 and the stabilizing cover 342.
[0033] Specifically, such as Figure 3 As shown, the mounting assembly 35 includes four mounting slots 351 located at the bottom of the motor body 9, and four threaded cylinders 352 located at the top of the mounting base 2. The threaded cylinders 352 are adapted to the mounting slots 351, and mounting screws 353 are connected to the internal threads of the threaded cylinders 352. The mounting screws 353 are in contact with the bottom of the motor body 9.
[0034] Specifically, such as Figure 3 The adjusting screw 32 shown has a threaded connection to a reinforcing nut 5 on one side. The reinforcing nut 5 and the locking nut 33 are located on both sides of the fixed base 31, respectively.
[0035] Specifically, such as Figure 2 As shown, the fixing seat 31 is welded to the top of the base 1, and two reinforcing rods 7 are provided at the bottom of the fixing seat 31. The reinforcing rods 7 are fixedly connected to the base 1 and are hexagonal in shape.
[0036] In use, the motor body 9 is fixed to the top of the mounting base 2 by the mounting assembly 35. When the motor body 9 is placed on the mounting base 2, the threaded cylinder 352 is located inside the mounting groove 351. The motor body 9 is fixed to the top of the mounting base 2 by the cooperation of the mounting screw 353 and the threaded cylinder 352. An adjustment mechanism 3 is provided between the base 1 and the mounting base 2. The four fixed seats 31 distributed on the four sides of the base 1 and the four adjusting screws 32 fixed on the four sides of the mounting base 2 are engaged with the locking screws threaded to the side wall of the adjusting screws 32. Nut 33 and reinforcing nut 5 allow adjustment of the mounting position of the mounting base 2. When adjustment is needed, loosen locking nut 33 and reinforcing nut 5. At this time, the mounting base 2 can move on top of the base 1 to adjust the mounting position. After adjustment, tighten the two nuts to fix it. A stabilizing component 34 is set at one end of the mounting base 2, placing the bearing ring 343 between the stabilizing seat 341 and the stabilizing cover 342. The stabilizing seat 341 and the stabilizing cover 342 limit and support the bearing ring 343, thereby stabilizing the output shaft of the motor body 9 and reducing its... Vibration and offset during operation are mitigated by the reinforcement rod 7, which enhances the connection strength between the fixed seat 31 and the base 1. The adjustment mechanism 3 allows for flexible adjustment of the mounting positions of the mounting base 2 and the motor body 9, meeting different installation environments and motor installation requirements. This ensures precise alignment between the motor body 9 and the machine tool spindle, improving transmission accuracy and machining quality. The adjustment screw 32, lock nut 33, and reinforcement nut 5, located on opposite sides of the fixed seat 31, provide a double-locking design, enhancing stability after adjustment and preventing changes in the mounting position due to vibration during use. This ensures reliable motor operation. The stabilizing component 34 provides excellent support and stability for the output shaft of the motor body 9. The bearing ring 343, under the combined action of the stabilizing seat 341 and the stabilizing cover 342, restricts radial and axial movement of the output shaft, reducing vibration and offset during motor operation, minimizing noise and wear caused by output shaft instability, and extending the service life of the motor and machine tool spindle.
[0037] Specifically, such as Figure 4 and Figure 5 As shown, the leveling and fixing mechanism 4 includes four leveling seats 41 disposed at the bottom of the base 1. The leveling seats 41 are Z-shaped and have two mounting holes 42 at the bottom. An adjusting rod 43 is threadedly connected to the middle of the leveling seat 41, and an adjusting plate 44 is disposed at the bottom of the adjusting rod 43.
[0038] Specifically, such as Figure 5 As shown, the bottom of the leveling seat 41 is provided with a receiving groove 6, and the adjusting plate 44 is located inside the receiving groove 6.
[0039] Specifically, such as Figure 5As shown, the bottom of the base 1 is provided with two support seats 8, which are I-shaped.
[0040] In use, a leveling and fixing mechanism 4 is set at the bottom of the base 1. Four Z-shaped leveling seats 41 are distributed at the bottom of the base 1. The bottom of the leveling seat 41 has mounting holes 42 for initial positioning and fixing. The middle of the leveling seat 41 is threaded to the adjusting rod 43. The bottom of the adjusting rod 43 is set with an adjusting plate 44. By rotating the adjusting plate 44, the adjusting rod 43 moves up and down in the leveling seat 41, thereby adjusting the level of the base 1 and making the entire mounting base level, ensuring the stability and accuracy of the motor installation. With the setting of the receiving groove 6, the adjusting plate 44 is located inside the leveling seat 41 when the mounting surface is level. The setting of the support seat 8 can provide auxiliary support for the base 1. Thus, through the setting of the leveling and fixing mechanism 4, the cooperation of the Z-shaped leveling seats 41, adjusting rod 43, and adjusting plate 44 makes the leveling operation of the base 1 more convenient. The level of the base 1 can be quickly adjusted by rotating the adjusting plate 44. The design of the mounting holes 42 makes it easy to fix the base to the machine tool bed, improving the stability and firmness of the installation.
[0041] By adopting the above technical solution, the problem that the existing motor mounting base cannot flexibly adjust the position of the spindle motor after installation is solved, which makes it difficult to accurately align the output shaft of the spindle motor with the machine tool spindle. At the same time, the existing mounting base does not reinforce the output shaft of the spindle motor, which makes the output shaft prone to misalignment.
[0042] Working principle: When using this application, the motor body 9 is first placed on the mounting base 2, and the threaded cylinder 352 is located inside the mounting groove 351. The motor body 9 is fixed to the top of the mounting base 2 by the cooperation of the mounting screw 353 and the threaded cylinder 352. An adjustment mechanism 3 is set between the base 1 and the mounting base 2. The mounting position of the mounting base 2 can be adjusted by the four fixed seats 31 distributed on the four sides of the base 1 and the four adjusting screws 32 fixed on the four sides of the mounting base 2, and the locking nuts 33 and reinforcing nuts 5 threadedly connected to the side walls of the adjusting screws 32. When adjustment is required, the locking screws are loosened. With the nut 33 and reinforcing nut 5 in place, the mounting base 2 can move on top of the base 1 to adjust the installation position. After adjustment, tighten the two nuts to fix it. Place the bearing ring 343 between the stabilizing seat 341 and the stabilizing cover 342. Use the stabilizing seat 341 and the stabilizing cover 342 to limit and support the bearing ring 343, thereby stabilizing the output shaft of the motor body 9 and reducing its vibration and offset during operation. By rotating the adjusting plate 44, the adjusting rod 43 moves up and down in the leveling seat 41, thereby adjusting the level of the base 1 and making the entire mounting base level, ensuring the stability and accuracy of the motor installation.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
