Description

Technical Field

[0001] This utility model relates to the field of servo motor technology, specifically a high-precision servo motor that can be installed with fine-tuning for alignment. Background Technology

[0002] Servo motors are high-precision, high-performance motors widely used in robotics, automation equipment, CNC machine tools, and other fields. To ensure the normal operation and long-term stability of servo motors, certain installation standards must be followed. The installation location of the servo motor should be protected from vibration and impact as much as possible. If vibration and impact cannot be avoided, appropriate damping measures, such as using damping pads, must be taken. Simultaneously, the installation of the servo motor should ensure the precision of the fit between the motor and the load shaft. Insufficient fit will lead to unstable torque output from the motor, affecting the accuracy and stability of the servo system. A type of servo motor with publication number "CN216216306U" is easy to install. It achieves position adjustment of the motor body by using a fixed block to move the motor body left and right. The self-locking mechanism of the worm gear and worm shaft fixes the position of the motor body, allowing operators to more easily adjust its position. This eliminates the need for drilling new holes on the mounting surface when connecting couplings of different lengths to the motor output end. However, in actual use, to ensure the relative positional accuracy between the servo motor output shaft and the load input shaft, repeated alignment is required during connection to guarantee their concentricity and reduce friction between the servo motor output shaft and the coupling during rotation, thus minimizing output torque reduction. This device relies solely on the sliding accuracy of the sliding structure for installation precision. As usage time increases, the sliding accuracy of the sliding structure decreases, compromising the installation accuracy of the servo motor. Utility Model Content

[0003] The purpose of this invention is to provide a high-precision servo motor that can be installed with fine-tuning to solve the problem of unreliable installation accuracy of servo motors mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-precision servo motor that can be finely adjusted for alignment, comprising a base disposed on one side of the device input end, a main motor that provides power output through an output shaft, a positioning post fixedly disposed on the surface of the main motor housing, a positioning ring mounted on the main motor through the positioning post, and locking bolts threadedly connected to the base at both ends of the positioning ring. The positioning ring is engaged with the main motor through the positioning post, and the positioning ring has a horseshoe-shaped design. The lower surfaces of both ends of the positioning ring are in contact with the upper surface of the base, and screw holes are provided at the contact points between the lower surfaces of the base and the lower surfaces of the positioning ring.

[0005] Preferably, the two lower end surfaces of the positioning ring are provided with adjustment grooves, and the adjustment grooves are elliptical in shape.

[0006] By adopting the above technical solution, the positioning ring can be adjusted in position by moving laterally relative to the locking bolt through the adjustment groove.

[0007] Preferably, the upper surface of the base has a groove, a rotating column is installed on the upper surface of the base, and a sliding positioning frame is installed on one side surface of the rotating column. A limit block is fixedly provided on the upper surface of the base. The upper end of the positioning frame is annular, and the end of the positioning frame connected to the rotating column is engaged with the limit block. The groove on the upper surface of the base is set directly opposite the positioning frame.

[0008] By adopting the above technical solution, the positioning frame can be stored in the groove on the upper surface of the base without affecting the normal use of the servo motor.

[0009] Preferably, a storage groove is formed on the upper surface of one end of the base, a calibration ring is inserted into one end of the base, an indicator light is fixedly installed on the outer surface of the calibration ring, and a clearance hole is formed on the outer surface of the calibration ring between the two indicator lights.

[0010] The above technical solution allows the calibration ring to be inserted into one end of the base through the storage slot when not in use, so that it will not be lost.

[0011] Preferably, a contact block is fixedly provided on the inner surface of the correction ring, and the inner surface of the correction ring between the two contact blocks is penetrated by a contact post. An ejector rod is fixedly provided at the upper end of the contact post, and a sliding connecting piece is provided on the side surface of the ejector rod. A centering post is engaged and installed on the side surface of the main motor away from the output shaft.

[0012] By adopting the above technical solution, the centering column can achieve the purpose of assisting the main motor in positioning by being concentric with the output shaft of the main motor.

[0013] Preferably, the inner surface of the contact block is arc-shaped, and the inner diameter of the contact block is the same as the outer diameter of the connecting piece, and a spring connects the connecting piece and the ejector rod.

[0014] By adopting the above technical solution, when the connecting piece slides, it can make contact with the contact block, thereby connecting the two contact blocks and lighting up the indicator light.

[0015] Preferably, the end of the centering column that engages with the main motor is hexagonal, and the other end of the centering column is circular. The outer surface of the cylindrical end of the centering column is in contact with the outer surface of the contact column. A spring connects the contact column and the correction ring.

[0016] By adopting the above technical solution, when the centering column deviates, it can squeeze the contact column, causing the contact column to slide and drive the connecting piece to slide. When the contact column is not under force, it will slide back to its original position with the support of the spring.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the high-precision servo motor that can be aligned and finely adjusted during installation:

[0018] 1. By using adjustment grooves at both ends of the positioning ring and fixing it with locking bolts, the elliptical adjustment grooves allow the positioning ring to move laterally through the gap between the adjustment grooves and the locking bolts when the locking bolts are fixing it, thus ensuring the installation accuracy of the servo motor and the load.

[0019] 2. During installation, the connection between the rotating column and the horizontally sliding positioning frame and the load input shaft is achieved by rotating the column. This allows the base as a whole to achieve precise positioning of the load input shaft through the ring design at the upper end of the positioning frame, thereby ensuring that the servo motor can be accurately installed with the load.

[0020] 3. By using the method of the positioning frame sliding laterally and engaging with the limit block, the relative distance between the ring design at the upper end of the positioning frame and the base is kept constant. This ensures that as long as the main motor is accurately positioned relative to the base, the relative position between the main motor and the load is also accurate. In this way, the installation process of the base and the main motor and the alignment process of the main motor and the load are separated, allowing the installation of the base and the main motor to be carried out independently, thus saving on-site installation time and improving work efficiency.

[0021] 4. By inserting the correction ring into one side surface of the base and contacting the centering column through the contact post, when the centering column and the correction ring are misaligned, the connecting piece will slide and contact the contact block through the contact post and the ejector rod. The indicator light is lit by connecting two adjacent contact blocks to facilitate the staff to observe the direction of the offset and make adjustments.

[0022] 5. The calibration ring and positioning frame are stored in the storage slot and the groove opposite the positioning frame on the upper surface of the base, so that the main motor will not be interfered with by the calibration ring and positioning frame during use, which facilitates the subsequent installation of external monitoring equipment and maintenance of the main motor.

[0031] 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.

[0033] Please see Figure 1 This utility model provides a technical solution: a high-precision servo motor that can be aligned and finely adjusted for installation, including a base 1 set on one side of the input end of the device, a main motor 2 that provides power output through an output shaft, a positioning post 3 fixedly set on the surface of the housing of the main motor 2, a positioning ring 4 installed on the main motor 2 through the positioning post 3, and locking bolts 6 that threadedly connect the two ends of the positioning ring 4 to the base 1. The positioning ring 4 is engaged with the main motor 2 through the positioning post 3, and the positioning ring 4 has a horseshoe-shaped design. The lower surfaces of both ends of the positioning ring 4 are in contact with the upper surface of the base 1, and screw holes are provided at the contact points between the lower surfaces of the base 1 and the two ends of the positioning ring 4.

[0034] The two lower ends of the positioning ring 4 are provided with adjustment grooves 5, and the adjustment grooves 5 are elliptical. During installation, the base 1 is first fixed to one side of the load equipment by the clamp. The main motor 2 and the positioning ring 4 are fixedly installed by the engagement of the positioning pin 3 and the positioning ring 4. At this time, the locking bolt 6 is inserted into the adjustment groove 5 and threadedly connected to the base 1, but the locking bolt 6 is not tightened. Then, the main motor 2 is moved laterally so that the output shaft of the main motor 2 is gradually aligned with the input shaft of the load. After the alignment is measured by external instruments, the locking bolt 6 is tightened to complete the fixed installation.

[0035] Example 2

[0036] Please see Figure 2-3 This utility model provides a technical solution: a high-precision servo motor that can be aligned and finely adjusted for installation, including a base 1 set on one side of the input end of the device, a main motor 2 that provides power output through an output shaft, a positioning post 3 fixedly set on the surface of the housing of the main motor 2, a positioning ring 4 installed on the main motor 2 through the positioning post 3, and locking bolts 6 that threadedly connect the two ends of the positioning ring 4 to the base 1. The positioning ring 4 is engaged with the main motor 2 through the positioning post 3, and the positioning ring 4 has a horseshoe-shaped design. The lower surfaces of both ends of the positioning ring 4 are in contact with the upper surface of the base 1, and screw holes are provided at the contact points between the lower surfaces of the base 1 and the two ends of the positioning ring 4.

[0037] The lower surfaces of the positioning ring 4 are provided with adjustment grooves 5, which are elliptical in shape. The upper surface of the base 1 is provided with a groove. A rotating column 7 is mounted on the upper surface of the base 1, and a sliding positioning frame 8 is mounted on one side surface of the rotating column 7.

The upper outer part of the positioning frame 8 is annular, and the end of the positioning frame 8 connected to the rotating column 7 engages with the limit block 9. The groove on the upper surface of the base 1 is aligned with the positioning frame 8. First, the main motor 2 is fixedly installed on the base 1 by engaging the positioning ring 4 with the positioning column 3 and using the locking bolt 6. On the upper surface, the relative positions of the main motor 2 and the base 1 are precisely fixed. Then, the rotating column 7 is rotated so that the positioning frame 8 flips upward and rotates out of the groove on the surface of the base 1. At this time, the positioning frame 8 slides laterally so that the ring at the upper end of the positioning frame 8 engages with one end of the input shaft of the load device. At this time, the positioning frame 8 engages with the limiting block 9 so that the relative angle between the positioning frame 8 and the base 1 is fixed and the ring at the upper end of the positioning frame 8 is concentric with the output shaft of the main motor 2, thus completing the positioning of the main motor 2 and the load device. Then, the base 1 is pressed and fixed on one side of the load device by the clamp, thus completing the installation of the main motor 2.

[0038] Example 3

[0039] Please see Figure 4-7This utility model provides a technical solution: a high-precision servo motor that can be aligned and finely adjusted during installation, including a base 1 set on one side of the device input end, a main motor 2 that provides power output through an output shaft, a positioning post 3 fixedly set on the surface of the housing of the main motor 2, a positioning ring 4 installed on the main motor 2 through the positioning post 3, and locking bolts 6 that threadedly connect the two ends of the positioning ring 4 to the base 1. The positioning ring 4 is engaged with the main motor 2 through the positioning post 3, and the positioning ring 4 has a horseshoe-shaped design. The lower surfaces of both ends of the positioning ring 4 are in contact with the upper surface of the base 1, and screw holes are provided at the contact points between the lower surfaces of the base 1 and the two ends of the positioning ring 4.

[0040] The positioning ring 4 has adjustment grooves 5 on its two lower ends, and the adjustment grooves 5 are elliptical in shape. A storage groove 10 is formed on the upper surface of one end of the base 1. A correction ring 11 is inserted into one end of the base 1, and an indicator light 12 is fixedly mounted on the outer surface of the correction ring 11. A clearance hole 13 is formed on the outer surface of the correction ring 11 between the two indicator lights 12. A contact block 14 is fixedly mounted on the inner surface of the correction ring 11, and a contact post 15 penetrates the inner surface of the correction ring 11 between the two contact blocks 14. An ejector rod 16 is fixedly mounted on the upper end of the contact post 15, and the side surface of the ejector rod 16 is provided with… The sliding connecting piece 17 has a centering column 18 engaged on the side surface of the main motor 2 away from the output shaft. The inner surface of the contact block 14 is arc-shaped, and the inner diameter of the contact block 14 is the same as the outer diameter of the connecting piece 17. A spring connects the connecting piece 17 and the ejector rod 16. The end of the centering column 18 that engages with the main motor 2 is hexagonal, and the other end of the centering column 18 is circular. The outer surface of the cylindrical end of the centering column 18 is in contact with the outer surface of the contact column 15. A spring connects the contact column 15 and the correction ring 11. During installation, the positioning ring 4 is first used to... With the positioning column 3 engaged and locking bolt 6 in place, the main motor 2 is mounted on the upper surface of the base 1, but not tightened. Then, the rotating column 7 is rotated and the positioning frame 8 is slid, causing the positioning frame 8 to engage with the limit block 9 and the input shaft of the load device. At this point, the correction ring 11 is removed from the storage slot 10 and inserted into one end of the base 1. Then, one end of the centering column 18 is passed through the correction ring 11 and inserted into the housing of the main motor 2 through its hexagonal design. At this point, the centering column 18 is concentric with the output shaft of the main motor 2. Then, observe whether the indicator light 12 on the correction ring 11 is lit. When the correction ring 11... When the indicator light 12 in a certain direction is lit, it indicates that the centering column 18 is offset in that direction relative to the input shaft of the load device. At this time, the position of the main motor 2 relative to the base 1 is adjusted by adjusting the adjustment groove 5 until the centering column 18 is concentric with the input shaft of the load device. At this time, since all the contact columns 15 are squeezed by the centering column 18, they will not drive the connecting piece 17 to contact the contact block 14 through the ejector rod 16 to light up the indicator light 12, thus completing the positioning of the main motor 2. At this time, tightening the locking bolt 6 can complete the installation, and the positioning hole 13 ensures that the ejector rod 16 can slide freely without obstruction when the contact column 15 is pressed.
