Description

Technical Field

[0001] This utility model relates to the field of calibration application technology, and more specifically, to a servo motor calibration mechanism. Background Technology

[0002] During the installation and calibration of servo motors and external transmission systems, traditional calibration mechanisms with fixed heights cannot adapt to different motor models. Calibration mechanisms for dual-axis mechanical positioning components rely on manual or simple tools to position the transmission shaft and output shaft, making it difficult to guarantee coaxiality. To solve these pain points in practical applications and meet diverse motor calibration needs, this servo motor calibration mechanism has emerged.

[0003] Existing publication number CN217953762U discloses a servo motor automatic control force gauge calibration device, including a base, a support beam on the base, and a locking shaft head connected in series from top to bottom on the support beam. A connecting shaft head is fixedly connected below the locking shaft head, and the lower end of the connecting shaft head is connected to a standard force gauge and a verification force gauge. The verification force gauge is positioned directly below the output end of an actuating cylinder, the other end of which is fixed to the base. This dual force gauge series connection ensures that the standard force gauge and the measuring force gauge are simultaneously subjected to the same tensile and compressive loads, resulting in high load consistency. In the process of developing this utility model, the inventors discovered the following problems with the existing technology:

[0004] Traditional servo motor calibration equipment without height adjustment components cannot flexibly adjust the height of the calibration mechanism according to the output shaft height of different servo motor models. As a result, a calibration device can often only be adapted to a specific model of motor. When different models of motors need to be calibrated, the corresponding calibration device must be replaced.

[0005] Therefore, a servo motor calibration mechanism is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a servo motor calibration mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a servo motor calibration mechanism, comprising a calibration mechanism, a lifting assembly, a support base, and a side plate. The support base is mounted above the lifting assembly, and a side plate is mounted on the side of the support base. The calibration mechanism is mounted on the side of the side plate away from the support base. The calibration mechanism includes a drive assembly, a sliding assembly, and a connecting sleeve. The sliding assembly is mounted on the outer diameter surface of the drive assembly, and a connecting sleeve is mounted above the sliding assembly.

[0008] Preferably, the drive assembly includes a motor, a connecting shaft, and a threaded rod, with the connecting shaft mounted on the side of the motor and the threaded rod mounted on the side of the connecting shaft away from the motor.

[0009] Preferably, the sliding assembly includes a threaded sleeve, a connecting rod, and a fixing plate, wherein the fixing plate is mounted on the side of the threaded sleeve, and the connecting rod is mounted on the side of the fixing plate away from the threaded sleeve.

[0010] Preferably, the connecting sleeve includes an upper limit ring, a lower limit ring, and an adjusting bolt, and a lower limit ring is provided below the upper limit ring, with the adjusting bolt installed on the inner diameter surface of the lower limit ring.

[0011] Preferably, the lifting assembly includes a cylinder, a push rod, and a push plate, with the push rod mounted above the cylinder and the push plate mounted above the push rod.

[0012] Preferably, the motor and the connecting shaft are connected by a coupling, and the connecting shaft and the threaded rod are connected by welding. The motor drives the threaded rod to rotate around its axis through the connecting shaft.

[0013] Preferably, the connecting lug on the side of the lower limit ring has a through hole, and the connecting lug on the side of the upper limit ring has a through hole, and the adjusting bolt and the threaded hole in the connecting lug of the lower limit ring are connected by threads.

[0014] Preferably, the threaded sleeve and the fixing plate are connected by welding, and the fixing plate and the connecting rod are connected by welding, wherein the connecting rod is an L-shaped stepped rod.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. Compared with the prior art, this servo motor calibration mechanism uses a lifting component to flexibly adjust the height of the calibration mechanism according to the model of the servo motor. Since different models of servo motors have different structural dimensions, the height of their output shafts often varies. The lifting component in this mechanism plays a key role. The lifting component includes a cylinder, a push rod, and a push plate. The cylinder is used as the power element. By controlling the change of air pressure inside the cylinder, the push rod can be driven to extend and retract, thereby driving the push plate on top to move up and down. The movement of the push plate will synchronously adjust the height of the support base connected to it and the calibration mechanism above, ultimately achieving the adaptation of the calibration mechanism to different models of servo motors in terms of height.

[0017] 2. Compared with existing technologies, this servo motor calibration mechanism can achieve calibration and positioning of the drive shaft and output shaft through a calibration mechanism. The calibration mechanism integrates a drive component, a sliding component, and a connecting sleeve. The motor in the drive component serves as a power source, driving the threaded rod to rotate around the axis through the connecting shaft. The threaded sleeve of the sliding component forms a threaded engagement with the threaded rod, converting the rotational motion of the threaded rod into its own linear motion. Then, through the rigid connection between the fixed plate and the connecting rod, the linear motion is transmitted to the connecting sleeve. The connecting sleeve includes an upper limit ring, a lower limit ring, and an adjusting bolt. The two sets of connecting sleeves can respectively fit the output shaft of the servo motor and the external drive shaft. By tightening the adjusting bolt, the upper and lower limit rings can firmly clamp the two shafts. Driven by the sliding component, the connecting sleeve can drive the two shafts to adjust their horizontal position until they are on the same axis. This positioning method ensures the coaxiality of the drive shaft and output shaft when connected. Attached Figure Description

[0023] 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.

[0024] Example 1

[0025] As attached Figures 1 to 4The servo motor calibration mechanism shown includes a calibration mechanism 1, a lifting assembly 2, a support base 3, and a side plate 4. The support base 3 is mounted on the top of the lifting assembly 2, and the side plate 4 is mounted on the side of the support base 3. The calibration mechanism 1 is mounted on the side of the side plate 4 away from the support base 3. The calibration mechanism 1 includes a drive assembly 5, a sliding assembly 6, and a connecting sleeve 7. The sliding assembly 6 is mounted on the outer diameter surface of the drive assembly 5, and the connecting sleeve 7 is mounted on the top of the sliding assembly 6.

[0026] Specifically: When the servo motor calibration mechanism adopts a layered assembly structure, with the lifting component 2 as the base support, the height of the servo motor calibration mechanism and the servo motor are adjusted to be consistent, and it is connected to and supports the side plate 4 through the bracket 3. The side plate 4 serves as the installation reference to fix the calibration mechanism 1. The calibration mechanism 1 integrates the drive component 5, the sliding component 6 and the connecting sleeve 7 to form a complete calibration execution system. The drive component 5 rotates to make the sliding component 6 move horizontally. The horizontal movement of the sliding component 6 will drive the two sets of connecting sleeves 7 installed on the output shaft of the servo motor and the external transmission shaft to move horizontally, thereby calibrating the position of the output shaft and the transmission shaft.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0029] In a preferred embodiment, the drive assembly 5 includes a motor 8, a connecting shaft 9, and a threaded rod 10. The connecting shaft 9 is mounted on the side of the motor 8, and the threaded rod 10 is mounted on the side of the connecting shaft 9 away from the motor 8. The drive assembly 5 serves as a power source, outputting torque through the motor 8, which is transmitted to the threaded rod 10 via the connecting shaft 9, so that the threaded rod 10 can drive the sliding assembly 6 to move linearly by rotation.

[0030] In a preferred embodiment, the sliding assembly 6 includes a threaded sleeve 11, a connecting rod 12, and a fixing plate 13. The fixing plate 13 is mounted on the side of the threaded sleeve 11, and the connecting rod 12 is mounted on the side of the fixing plate 13 away from the threaded sleeve 11. The sliding assembly 6 forms a threaded engagement with the threaded rod 10 of the drive assembly 5 through the threaded sleeve 11, converting the rotational motion of the threaded rod 10 into the linear motion of the threaded sleeve 11. Then, through the rigid connection between the fixing plate 13 and the connecting rod 12, the linear motion is transmitted to the connecting sleeve 7, so that the connecting sleeve 7 can move linearly along the axis of the servo motor output shaft and the external transmission shaft, ensuring that the two are on the same axis, and realizing the calibration and adjustment of the position between the output shaft and the external transmission shaft.

[0031] In a preferred embodiment, the connecting sleeve 7 includes an upper limit ring 14, a lower limit ring 15, and an adjusting bolt 16. The lower limit ring 15 is located below the upper limit ring 14, and the adjusting bolt 16 is installed on the inner diameter surface of the lower limit ring 15. The connecting sleeve 7 forms a ring structure through the cooperation of the upper limit ring 14 and the lower limit ring 15. The two sets of connecting sleeves 7 are used to fit and position whether the output shaft of the servo motor and the external transmission shaft are on the same straight line. The adjusting bolt 16 passes through the connecting ear of the limit ring and adjusts the tightness of the limit ring by tightening or loosening it, thereby connecting the two sets of connecting sleeves 7 of the calibration mechanism to the output shaft of the servo motor and the external transmission shaft, respectively.

[0032] In a preferred embodiment, the lifting assembly 2 includes a cylinder 17, a push rod 18, and a push plate 19. The push rod 18 is mounted above the cylinder 17, and the push plate 19 is mounted above the push rod 18. The lifting assembly 2 uses the cylinder 17 as a power element. The push rod 18 is driven to extend and retract by the change in air pressure inside the cylinder 17. The push rod 18 drives the push plate 19 at the top to move up and down, thereby adjusting the height of the support base 3 and the calibration mechanism above, so as to achieve height adaptation between the calibration mechanism and the servo motor.

[0033] In a preferred embodiment, the motor 8 and the connecting shaft 9 are connected by a coupling, and the connecting shaft 9 and the threaded rod 10 are connected by welding. The motor 8 drives the threaded rod 10 to rotate around its axis through the connecting shaft 9.

[0034] In a preferred embodiment, the connecting lug on the side of the lower limit ring 15 is machined with a through hole, the connecting lug on the side of the upper limit ring 14 is machined with a through hole, and the adjusting bolt 16 and the threaded hole in the connecting lug of the lower limit ring 15 are connected by threads.

[0035] In a preferred embodiment, the threaded sleeve 11 and the fixing plate 13 are connected by welding, and the fixing plate 13 and the connecting rod 12 are connected by welding. The connecting rod 12 is an L-shaped stepped rod.

[0036] The working process of this utility model is as follows: First, when the operator uses the equipment to calibrate the servo motor, the equipment is placed in a suitable position. By controlling the cylinder 17 in the lifting assembly 2, the push rod 18 drives the push plate 19 to move up and down, and the height of the support base 3 and the upper structure is adjusted to ensure that the calibration mechanism 1 and the servo motor are at the appropriate height.

[0037] Subsequently, the servo motor output shaft and the external transmission shaft are respectively placed into the two sets of connecting sleeves 7. By tightening the adjusting bolts 16 on the side connecting ears of the lower limit ring 15 and the upper limit ring 14, the two sets of connecting sleeves 7 are used to firmly clamp the output shaft and the transmission shaft respectively. Next, check whether the calibration mechanism 1 fixed on the side plate 4 is stable. Start the motor 8 in the drive assembly 5. The motor 8 drives the connecting shaft 9 to rotate through the coupling. The connecting shaft 9 drives the threaded rod 10 to rotate around the axis. At this time, the threaded sleeve 11 in the sliding assembly 6 moves horizontally due to the threaded engagement with the threaded rod 10. The threaded sleeve 11 drives the L-shaped stepped connecting rod 12 to move synchronously through the fixed plate 13 welded to it, thereby driving the two sets of connecting sleeves 7 to adjust their horizontal positions until the servo motor output shaft and the external transmission shaft are on the same axis through the positioning of the connecting sleeves 7. The output shaft and the transmission shaft are then connected through the coupling. Finally, turn off the motor 8 and check each connection part again to complete the calibration operation. The above is the working principle of this servo motor calibration mechanism.
