Description

Technical Field

[0001] This application relates to the field of dynamic balancing testing, and in particular to a drive mechanism for dynamic balancing testing. Background Technology

[0002] Dynamic balancing testing is a technical process that uses a balancing testing device to dynamically balance rotating workpieces (such as motor rotors). Its purpose is to eliminate vibration, noise, and equipment wear caused by uneven mass distribution of rotating workpieces.

[0003] In the prior art, when performing dynamic balancing tests, a robotic arm is usually used to move the rotating workpiece to the test position, and then the rotating workpiece is driven to rotate by a belt drive mechanism to complete the dynamic balancing test during the rotation of the rotating workpiece.

[0004] However, since the belt drive mechanism is fixed to the side of the test position, it will interfere with the loading and unloading of the robot, affecting the loading and unloading efficiency of the robot. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this application provides a drive mechanism for dynamic balancing testing that can avoid manipulators.

[0006] The driving mechanism for dynamic balancing testing provided in this application adopts the following technical solution:

[0007] A drive mechanism for dynamic balancing testing includes a support, a drive component disposed on the support, a mounting frame disposed on the support, the drive component being movably disposed around the mounting frame in the circumferential direction, and the drive mechanism further includes a drive component for driving the drive component to move.

[0008] By adopting the above technical solution, the drive component can be moved away from the robot during its movement to prevent it from interfering with the robot's loading and unloading.

[0009] In one specific implementation, the drive mechanism further includes a rocker arm, the two ends of which are rotatably connected to the drive assembly and the mounting bracket, respectively.

[0010] By adopting the above technical solution, the rocker arm can drive the drive assembly to move around the mounting frame during its rotation. This not only improves the movement stability of the drive assembly, but also provides a large movement stroke for the drive assembly during its rotation, thereby further preventing the drive assembly from interfering with the loading and unloading of the robot.

[0011] In one specific implementation, the drive assembly is provided with a rotating pin, which is rotatably connected to the rocker arm.

[0012] By adopting the above technical solution, the drive component can be kept in a state of relative rotation with the rocker arm through the rotating pin, so as to avoid the drive component getting stuck during the movement.

[0013] In one specific implementation, the drive mechanism further includes a guide rod rotatably connected to the mounting bracket, and a rotating pin passing through the rocker arm axially with its end connected to the guide rod.

[0014] By adopting the above technical solution, the guide rod can guide the movement of the drive component during its rotation, thereby preventing the drive component from deviating during movement.

[0015] In one specific implementation, a rotating seat is fitted onto the guide rod, and the rotating seat is rotatably connected to the mounting frame.

[0016] By adopting the above technical solution, the rotational stability of the guide rod is effectively improved, thereby enhancing its guiding effect on the drive assembly.

[0017] In one specific implementation, the drive assembly includes a drive plate, a rotatable drive wheel mounted on the drive plate, a first drive member for driving the drive wheel to rotate, a rotatable driven wheel mounted on the drive plate, and a drive belt that is drively connected to the drive wheel and the driven wheel.

[0018] By adopting the above technical solution, the drive belt can move stably with the cooperation of the driving wheel and the driven wheel, effectively improving the driving effect of the drive belt on the rotating workpiece.

[0019] In one specific implementation, the drive assembly includes a rotating shaft rotatable about its own axis and mounted on the mounting bracket, a second drive member for driving the rotating shaft to rotate, and the rotating shaft being connected to the rocker arm.

[0020] In one specific implementation, the mounting frame includes a back plate, a frame body disposed on the back plate, a second drive member disposed on the back plate, a rotating shaft passing through the frame body, a gap between the back plate and the frame body, and the drive assembly further includes a rotatable transmission disk disposed in the gap, with both ends of the transmission disk coaxially connected to the rotating shaft and the output end of the second drive member, respectively.

[0021] By adopting the above technical solution, the second driving component can drive the rotating shaft to rotate stably through the transmission disc, effectively improving the rotational stability of the rotating shaft.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] The drive assembly can move away from the robot during its movement to prevent it from interfering with the robot's loading and unloading. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] See Figure 1 As shown, a drive mechanism for dynamic balancing testing includes an upright support 1, a drive assembly 2 mounted on the support 1, and a mounting frame 3 at the upper end of the support 1. The drive assembly 2 is movably mounted around the mounting frame 3 in the circumferential direction. The drive mechanism also includes a drive assembly 4 for driving the drive assembly 2. A rocker arm 5 is mounted on the mounting frame 3, with both ends rotatably connected to the drive assembly 2 and the mounting frame 3, respectively. The rotation axis of the rocker arm 5 extends horizontally. The drive assembly 4 is a motor for driving the rocker arm 5 to rotate.

[0029] When the robot arm is loading and unloading, the drive assembly 4 drives the rocker arm 5 to rotate clockwise. The rocker arm 5 drives the drive assembly 2 to move upward around the circumference of the mounting frame 3, thereby moving it away from the robot arm to prevent it from interfering with the loading and unloading of the robot arm. After the robot arm has finished loading and unloading, the drive assembly 4 drives the rocker arm 5 to rotate counterclockwise. The rocker arm 5 drives the drive assembly 2 to move downward around the circumference of the mounting frame 3 and reset.

[0030] In this embodiment, the drive assembly 2 is provided with a rotating pin 21 extending horizontally. The axial direction of the rotating pin 21 is perpendicular to the length direction of the rocker arm 5. The rotating pin 21 passes through the rocker arm 5 along its axial direction and is rotatably connected to the rocker arm 5. A bearing is also provided between the rotating pin 21 and the rocker arm 5. During the rotation of the rocker arm 5, the drive assembly 2 can maintain a relatively rotatable state with the rocker arm 5 through the rotating pin 21, so as to avoid jamming of the drive assembly 2 during movement.

[0031] In this embodiment, the driving mechanism further includes a guide rod 6 and a rotating seat 7 sleeved on the guide rod 6. The rotating seat 7 is rotatably connected to the mounting frame 3 via a pin. A bearing is provided between the pin and the mounting frame 3. The axial direction of the rotating pin 21 is perpendicular to the axial direction of the guide rod 6. The rotating pin 21 passes through one end of the rocker arm 5 and connects to the lower end of the guide rod 6. When the rocker arm 5 rotates clockwise, it drives the driving assembly 2 to move upward. At this time, the guide rod 6 rotates counterclockwise under the drive of the rotating pin 21. In this way, the guide rod 6 can guide the movement of the driving assembly 2 through its rotation, so as to prevent the driving assembly 2 from deviating during the movement.

[0032] In this embodiment, the drive assembly 2 includes a drive plate 22, a rotatable drive wheel 23 mounted on the drive plate 22, a first drive member 24 for driving the drive wheel 23 to rotate, two rotatable driven wheels 25 mounted on the drive plate 22, and a drive belt 26 connected to the drive wheel 23 and the driven wheels 25. The length direction of the drive plate 22 is the same as the axial direction of the rotating pin 21, and the extension direction of the rotation axes of the drive wheel 23 and the driven wheels 25 is perpendicular to the length direction of the drive plate 22. The first drive member 24 is a motor, and the drive belt 26 is a belt. The drive belt 26 can move stably with the cooperation of the drive wheel 23 and the driven wheels 25, effectively improving the driving effect of the drive belt 26 on the rotating workpiece.

[0033] In this embodiment, the drive assembly 4 includes a rotating shaft 41 rotatable about its own axis and mounted on the mounting bracket 3, and a second drive member 42 for driving the rotating shaft 41 to rotate. The rotating shaft 41 is connected to the rocker arm 5, and the axial direction of the rotating shaft 41 is perpendicular to the length direction of the rocker arm 5. The second drive member 42 is a motor.

[0034] Furthermore, the mounting frame 3 includes a back plate 31, a frame body 32 mounted on the back plate 31, a second drive member 42 mounted on the back plate 31, and a rotating shaft 41 passing through the frame body 32. A gap exists between the back plate 31 and the frame body 32. The drive assembly 4 also includes a rotatable transmission disk 43 disposed within the gap. A rotating seat 7 is located at the end of the back plate 31. The diameter of the transmission disk 43 is larger than the diameter of the rotating shaft 41. Both ends of the transmission disk 43 are coaxially connected to the output ends of the rotating shaft 41 and the second drive member 42, respectively. The second drive member 42 can drive the rotating shaft 41 to rotate stably via the transmission disk 43, effectively improving the rotational stability of the rotating shaft 41.

[0035] The implementation principle of the driving mechanism in this application embodiment is as follows:

[0036] When the robot arm is loading and unloading, the drive assembly 4 drives the rocker arm 5 to rotate clockwise. The rocker arm 5 drives the drive assembly 2 to move upward around the circumference of the mounting frame 3 and away from the robot arm. After the robot arm has finished loading and unloading, the drive assembly 4 drives the rocker arm 5 to rotate counterclockwise. The rocker arm 5 drives the drive assembly 2 to move downward around the circumference of the mounting frame 3 and reset.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
