Description

Technical Field

[0001] This application relates to the field of balance testing, and in particular to a balance testing apparatus. Background Technology

[0002] Dynamic balancing testing is a technical process for detecting and correcting the dynamic balance of rotating bodies (such as motor rotors), aiming to eliminate vibrations, noise, and equipment losses caused by uneven mass distribution. In existing technologies, dynamic balancing tests are typically performed using balancing testing equipment. To improve testing efficiency, robotic arms are often used on these balancing testing equipment to load and unload the rotating bodies.

[0003] However, existing balance testing equipment has a belt installed on the side of the test position to drive the rotating body. Due to the interference of the belt, the robot often needs to move a longer distance to complete the loading and unloading of the rotating body, which undoubtedly greatly reduces the loading and unloading efficiency of the rotating body. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides a balance testing device that can improve the loading and unloading efficiency of rotating bodies.

[0005] The balance testing device provided in this application adopts the following technical solution:

[0006] A balance testing device includes a detection component and a drive component. The detection component has a detection position, and the drive component includes a drive part movably disposed along a direction close to or away from the detection position, and a first drive module for driving the drive part to move.

[0007] By adopting the above technical solution, the drive unit can move away from the detection position when the robot arm is performing loading and unloading operations, so as to avoid the drive unit interfering with the robot arm's stroke and improve the loading and unloading efficiency of the rotating body.

[0008] In one specific implementation, the drive unit includes a base plate, a drive wheel rotatably disposed on the base plate, a second drive module for driving the drive wheel to rotate, a driven wheel rotatably disposed on the base plate, and a drive belt connected to the drive wheel and the driven wheel.

[0009] 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 body.

[0010] In one specific implementation, the driving unit further includes a rotatable transmission wheel disposed on the base plate and located between the driving wheel and the driven wheel. There are two driving belts, one of which is drivingly connected to the driving wheel and the transmission wheel, and the other of which is drivingly connected to the transmission wheel and the driven wheel.

[0011] By adopting the above technical solution, the tension of the drive belt is effectively improved, thereby enhancing the driving effect of the drive belt on the rotating body.

[0012] In one specific implementation scheme, the first drive module includes a first movable seat that can be translatably arranged, a first drive member for driving the first movable seat to translate, a second movable seat that can be raised and lowered and arranged on the first movable seat, and a second drive member for driving the second movable seat to rise and fall, wherein the drive unit is arranged on the second movable seat.

[0013] By adopting the above technical solution, the drive unit can move horizontally and vertically with the cooperation of the first and second moving seats, effectively avoiding interference between the drive unit and the robot's stroke.

[0014] In one specific implementation scheme, the first movable seat is provided with a mounting part, and the upper and lower sides of the mounting part are respectively provided with limit posts. The upper and lower ends of the second movable seat are respectively provided with mating parts, and the two limit posts are respectively located on the lifting paths of the two mating parts.

[0015] By adopting the above technical solution, the lifting stroke of the second moving seat can be limited by two limit columns, preventing the second moving seat from lifting excessively and affecting the driving effect of the driving part on the rotating body.

[0016] In one specific implementation, the detection assembly includes two detection modules arranged opposite to each other, with the detection position located between the two detection modules. Each detection module includes a detection seat, a support plate disposed on the detection seat, a spring plate disposed in the detection seat and connected to the support plate, and a vibration sensor for detecting the amplitude of the spring plate.

[0017] By adopting the above technical solution, the bearing plate and the spring plate can cooperate with each other and output the unbalance of the rotating body. The vibration sensor can detect the unbalance with high detection accuracy.

[0018] In one specific implementation scheme, the detection component further includes a base, at least one guide rail disposed on the base, and two third movable seats respectively slidably disposed on the at least one guide rail. The two third movable seats correspond one-to-one with the two detection modules, and each detection module is respectively raised and lowered on the corresponding third movable seat.

[0019] By adopting the above technical solution, the height of the two detection modules and the distance between them can be flexibly adjusted according to the specifications of the rotating body, effectively expanding the application range of the detection components.

[0020] In one specific implementation, the balance testing device further includes a clamping assembly located to the side of the detection position, comprising a gripper movably disposed along a direction approaching or away from the detection position, and a third drive module for driving the gripper to move.

[0021] By adopting the above technical solution, the gripper can adjust its gripping position according to the specifications of the rotating body, effectively expanding the application range of the gripping component.

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

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] See Figure 1 As shown, a balance testing device is shown for performing dynamic balance tests on rotating bodies such as motor rotors. It includes a base 4, on which a detection component 1 and a drive component 2 are arranged along its length. The detection component 1 has a detection position, and the drive component 2 includes a drive part 21 that is movably arranged along the direction close to or away from the detection position, and a first drive module 22 for driving the drive part 21 to move.

[0034] When the robotic arm is loading and unloading the rotating body 100, the first drive module 22 can drive the drive unit 21 away from the detection position. At this time, the robotic arm can move directly to the detection position and complete the loading and unloading of the rotating body 100, which effectively improves the loading and unloading efficiency of the rotating body 100. After the robotic arm completes the loading and unloading action, the first drive module 22 drives the drive unit 21 back to the detection position. The drive unit 21 can drive the rotating body 100 at the detection position so that the rotating body 100 completes the dynamic balance test during rotation.

[0035] In this embodiment, the driving unit 21 includes an upright base plate 211, a drive wheel 212 rotatable about the width of the base 4 and mounted on the base plate 211, a second drive module 213 for driving the drive wheel 212 to rotate, a driven wheel 214 rotatable about the width of the base 4 and mounted on the base plate 211, and a driving belt 215 connected to the drive wheel 212 and the driven wheel 214. The base plate 211 extends along the length of the base 4, the second drive module 213 is a motor, the drive wheel 212 and the driven wheel 214 are located at opposite ends of the base plate 211 along its length, and the driving belt 215 is a belt. When driving the rotating body 100, the second drive module 213 drives the drive wheel 212 to rotate, which in turn drives the driving belt 215 and the driven wheel 214 to move. During its movement, the driving belt 215 drives the rotating body 100 to rotate.

[0036] In this embodiment, the driving unit 21 further includes a rotatable transmission wheel 216 disposed on the base plate 211 and located between the driving wheel 212 and the driven wheel 214. There are two driving belts 215, one of which is connected to the driving wheel 212 and the transmission wheel 216, and the other is connected to the transmission wheel 216 and the driven wheel 214. The winding positions of the two driving belts 215 on the transmission wheel 216 are arranged along the axial direction of the transmission wheel 216. By providing the transmission wheel 216, the tension of the driving belts 215 can be effectively increased, thereby improving the driving effect of the driving belts 215 on the rotating body 100.

[0037] In this embodiment, the first drive module 22 includes a first movable seat 221 translatably mounted on the base 4 along the width direction of the base 4, a first drive member 222 for driving the first movable seat 221 to translate, a second movable seat 223 movably mounted on the first movable seat 221, and a second drive member 224 for driving the second movable seat 223 to rise and fall. A drive unit 21 is mounted on the second movable seat 223. Both the first drive member 222 and the second drive member 224 are cylinders. The drive unit 21 can move horizontally and vertically with the cooperation of the first movable seat 221 and the second movable seat 223, effectively avoiding interference between the drive unit 21 and the robot's stroke.

[0038] In this embodiment, the base 4 includes two seat bodies 41 arranged side by side along its width direction, and two parallel first guide posts 5 are provided between the two seat bodies 41. The lower end of the first movable seat 221 is slidably connected to the two first guide posts 5. Two upright second guide posts 6 are provided at the upper end of the first movable seat 221, and the second movable seat 223 is slidably connected to the two second guide posts 6.

[0039] In this embodiment, the upper side of the first movable seat 221 is also provided with a mounting part 225. Limiting posts 226 are respectively provided on the upper and lower sides of the mounting part 225, with the two limiting posts 226 located at opposite corners of the mounting part 225. The upper and lower ends of the second movable seat 223 are respectively provided with mating parts 227, with the two mating parts 227 located at opposite corners of the second movable seat 223. The two limiting posts 226 correspond one-to-one with the two mating parts 227, and are respectively located on the lifting paths of the two mating parts 227. When the second movable seat 223 rises and falls, the two limiting posts 226 can abut against the corresponding mating parts 227 during the rising and falling strokes of the second movable seat 223, thereby limiting the second movable seat 223 and preventing excessive rising and falling of the second movable seat 223 from affecting the driving effect of the driving part 21 on the rotating body 100.

[0040] In this embodiment, the detection component 1 includes two detection modules 11 arranged opposite each other along the width direction of the base 4. The detection position is located between the two detection modules 11. Each detection module 11 includes a detection seat 111, a support plate 112 disposed on the detection seat 111, a spring piece 113 disposed in the detection seat 111 and connected to the support plate 112, and a vibration sensor 114 for detecting the amplitude of the spring piece 113. After the robot arm places the rotating body 100 on the two support plates 112, the drive unit 21 drives the rotating body 100 to rotate. The spring piece 113 can output the unbalance of the rotating body 100 outward through its own vibration. The vibration sensor 114 can detect the amplitude of the spring piece 113 to obtain the unbalance of the rotating body 100, and the detection accuracy is high.

[0041] Furthermore, the detection assembly 1 also includes a base 12, two guide rails 13 disposed on the base 12, and two third movable seats 14 respectively slidably disposed on the two guide rails 13. The two guide rails 13 are parallel to each other and extend along the width direction of the base 4. The two third movable seats 14 correspond one-to-one with the two detection modules 11, and each detection module 11 is respectively mounted on the corresponding third movable seat 14 in a liftable manner. Among them, the third movable seat 14 is provided with a first locking pin 7, which can lock the third movable seat 14 relative to the guide rails 13. The third movable seat 14 is also provided with two upright third guide posts 8, and the detection seat 111 is slidably connected to the two third guide posts 8. The detection seat 111 is provided with two second locking pins 9, which are used to lock the detection seat 111 relative to the two third guide posts 8 respectively. In this way, the operator can adjust the height of the detection seat 111 and the distance between the two detection seats 111 according to the specifications of the rotating body 100, and then lock them by the first locking pin 7 and the second locking pin 9, effectively expanding the application range of the detection component 1.

[0042] In this embodiment, a proximity sensor is also provided between the two detection seats 111. The proximity sensor is used to detect the distance between the two detection seats 111 so that the distance can match the length of the rotating body 100.

[0043] In this embodiment, the balance testing device further includes a clamping assembly 3, located to the side of one of the support plates 112. The clamping assembly 3 includes a gripper 31 movably disposed along a direction approaching or away from the detection position, and a third drive module 32 for driving the gripper 31 to move. The third drive module 32 is a cylinder. The gripper 31 has a clamping groove for accommodating a rotating body 100, with the rotating body 100 in clearance fit with the clamping groove. During testing, the gripper 31 can approach the support plate 112 and clamp the rotating body 100, with the end of the rotating body 100 housed in the clamping groove. As the rotating body 100 rotates, the gripper 31 can limit its axial position to improve the rotational stability of the rotating body 100.

[0044] Furthermore, a limiting plate 115 is also provided on the side of another bearing plate 112, which can limit the axial position of the rotating body 100. The limiting plate 115 is arranged opposite to the gripper 31, and the two ends of the rotating body 100 abut against the inner wall of the clamping groove and the limiting plate 115, respectively.

[0045] The implementation principle of a balance testing device according to an embodiment of this application is as follows:

[0046] The first drive module 22 drives the drive unit 21 to rise and move horizontally, moving the drive unit 21 away from the detection position. The robot arm moves the rotating body 100 onto the two carrier plates 112. Then, the first drive module 22 drives the drive unit 21 to reset. The drive belt 215 abuts against the rotating body 100 and drives the rotating body 100 to rotate. The detection component 1 performs a dynamic balance test on the rotating body 100. After the test is completed, the first drive module 22 drives the drive unit 21 to rise and move horizontally, moving the drive unit 21 away from the detection position. The robot arm grabs the rotating body 100 away from the carrier plate 112.

[0047] 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.
