Description

Technical Field

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

[0002] Dynamic balancing and weight removal refers to the technical process of dynamically balancing and correcting rotating workpieces (such as motor rotors) through a weight removal mechanism. Its purpose is to eliminate vibration, noise and equipment wear caused by uneven mass distribution.

[0003] The existing dynamic balancing and weight removal mechanisms are equipped with clamps that cannot effectively clamp rotating workpieces, causing the workpieces to easily shift during the weight removal process, which greatly affects the weight removal quality of the rotating workpieces. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides a dynamic balancing and weight-removing mechanism that can effectively clamp rotating workpieces.

[0005] The dynamic balancing and weight-reducing mechanism provided in this application adopts the following technical solution:

[0006] A dynamic balancing and weight-removing mechanism includes a base, a load-bearing component and a weight-removing component disposed on the base. The dynamic balancing and weight-removing mechanism further includes a clamping component disposed on the base. The clamping component includes a clamping seat movably disposed along a direction close to or away from the load-bearing component, a first drive module for driving the clamping seat to move, a clamping plate hinged to the clamping seat, and a second drive module for driving the clamping plate to rotate. The second drive module includes a module body and a drive part. The module body is hinged to the clamping seat, and the drive part is hinged to the clamping plate.

[0007] By adopting the above technical solution, the clamping plate can approach the bearing component and clamp onto the rotating workpiece under the drive of the first drive module and the second drive module, preventing the rotating workpiece from shifting during the weight removal process. At the same time, by hinged to the module body and the clamping seat, and hinged to the drive unit and the clamping plate, the clamping plate can have a larger range of motion during rotation, effectively improving the clamping effect of the clamping plate.

[0008] In one specific implementation, the clamping seat includes a base plate and a support disposed on the base plate. The base plate is hinged to the module body, and the support is hinged to the clamping plate.

[0009] In one specific implementation, a clearance groove is provided on the base plate, and the module body is movably accommodated in the clearance groove.

[0010] By adopting the above technical solution, the clearance groove can provide movement space for the module body and prevent the base plate from interfering with the rotation of the module body.

[0011] In one specific implementation scheme, the module body is provided with rotating shafts on both sides, and the base plate is provided with two rotating frames. The two rotating frames are located on both sides of the module body and are respectively hinged to the two rotating shafts.

[0012] By adopting the above technical solution, the module body can achieve stable rotation through the cooperation of the rotating shaft and the rotating frame, thereby further improving the clamping effect of the clamping plate.

[0013] In one specific implementation scheme, the module body includes a main body and a connecting part, the driving part is retractably disposed on the main body, the connecting part is located between the main body and the driving part, and the two rotating shafts are respectively disposed on both sides of the connecting part.

[0014] In one specific implementation, the connecting part is further provided with a clearance opening, and the driving part is retractably inserted into the clearance opening.

[0015] By adopting the above technical solution, the drive unit can extend along the relief opening and drive the clamping plate to rotate, preventing the connecting part from interfering with the extension and retraction of the drive unit.

[0016] In one specific implementation, the clamping seat is provided with first protrusions on both sides of its moving direction, and buffer modules are provided on both sides of the base. The two first protrusions correspond one-to-one with the two buffer modules. Each buffer module includes two buffer posts arranged opposite each other. The two buffer posts are arranged along the moving direction of the clamping seat, and the first protrusion is located between the two buffer posts.

[0017] By adopting the above technical solution, the two buffer posts can abut against the first protrusion during the movement of the clamping seat, thereby achieving movement buffering of the clamping seat and preventing the clamping seat from being damaged by rigid impact with the machine base.

[0018] In one specific implementation, a positioning module is provided on at least one side of the base. The positioning module is located close to the buffer module and includes a positioning block and two sensors disposed on the positioning block. The positioning block extends along the moving direction of the clamping seat. The two sensors are respectively located at both ends of the length direction of the positioning block. At least one of the two first protrusions is provided with a sensing plate. The sensing plate can pass through the two sensors respectively during the movement of the clamping seat.

[0019] By adopting the above technical solution, the two sensors can position the sensing sheet when it passes by, thereby enabling the positioning of the clamping seat and allowing the clamping seat to stop at the corresponding position as needed.

[0020] In one specific implementation, the dynamic balancing and weight-removing mechanism further includes a corner assembly disposed on the base. The corner assembly includes a corner seat movably disposed along a direction close to or away from the bearing assembly, a third drive module for driving the corner seat to move, a gripper module rotatable about its own axis disposed on the corner seat, and a fourth drive module for driving the gripper module to rotate. At least one side of the corner seat is provided with a second protrusion, and a buffer is provided between the second protrusion and the base.

[0021] By adopting the above technical solution, the gripper module can drive the rotating workpiece to rotate during the weight removal process, so as to remove weight at different positions in the radial direction of the rotating workpiece; at the same time, when the gripper module rotates, the buffer can buffer the vibration of the corner seat and prevent the rotating workpiece from being damaged during the rotation.

[0022] In one specific implementation, the dynamic balancing and weight-reducing mechanism further includes a push rod assembly disposed on the base. The push rod assembly is disposed opposite to the corner assembly and includes a push rod frame, a push rod shaft disposed on the push rod frame that is movable in a direction close to or away from the bearing assembly, and a fifth drive module for driving the push rod shaft to move. The axis of the push rod shaft coincides with the center line of the gripper module.

[0023] By adopting the above technical solution, the push rod shaft can abut against the end of the rotating workpiece during movement, effectively improving the rotational stability of the rotating workpiece.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The clamping plate can approach the bearing component and clamp onto the rotating workpiece under the drive of the first drive module and the second drive module to prevent the rotating workpiece from shifting during the weight removal process;

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] See Figure 1 As shown, a dynamic balancing and weight-removing mechanism is illustrated, including a base 1, a load-bearing component 2, a weight-removing component 3, and a clamping component 4 disposed on the base 1. The load-bearing component 2 is located in the middle of the base 1, and the weight-removing component 3 and the clamping component 4 are located at the two ends of the base 1 along its length.

[0038] The clamping assembly 4 includes a clamping seat 41 movably disposed along a direction close to or away from the bearing assembly 2, a first drive module 42 for driving the clamping seat 41 to move, a clamping plate 43 hinged to the clamping seat 41, and a second drive module 44 for driving the clamping plate 43 to rotate. The direction of movement of the clamping seat 41 is the same as the length direction of the base 1. The first drive module 42 is a cylinder. The rotation axis of the clamping plate 43 extends along the width direction of the base 1. The second drive module 44 includes a module body 441 and a drive part 442. The module body 441 is hinged to the clamping seat 41, and the drive part 442 is hinged to the clamping plate 43. The rotation axis between the module body 441 and the clamping seat 41 and the rotation axis between the drive part 442 and the clamping plate 43 extend along the width direction of the base 1, respectively.

[0039] When removing weight from a rotating workpiece, the workpiece is first placed on the support assembly 2. Then, the first drive module 42 drives the clamping seat 41 to approach the support assembly 2, and the second drive module 44 drives the clamping plate 43 to rotate and clamp onto the rotating workpiece. Finally, the weight removal assembly 3 performs weight removal processing on the rotating workpiece. This prevents displacement of the rotating workpiece during the weight removal process. Simultaneously, by hinged between the module body 441 and the clamping seat 41, and between the drive unit 442 and the clamping plate 43, during the rotation of the clamping plate 43 driven by the second drive module 44, the module body 441 and the clamping seat 41, and the drive unit 442 and the clamping plate 43, are all in a state of relative rotation. This allows the clamping plate 43 to have greater mobility during rotation, effectively improving the clamping effect of the clamping plate 43.

[0040] In this embodiment, the clamping seat 41 includes a horizontally arranged base plate 411 and a support 412 that is vertically arranged at one end of the base plate 411 near the bearing component 2. The base plate 411 is hinged to the module body 441, and the upper end of the support 412 is hinged to the clamping plate 43. The driving part 442 can extend and retract in the vertical direction and push the clamping seat 41 to rotate.

[0041] Furthermore, a square clearance groove 45 is provided on the base plate 411, and the module body 441 is movably accommodated in the clearance groove 45. During the process of the second drive module 44 driving the clamping plate 43 to rotate, the clearance groove 45 can provide movement space for the module body 441 and prevent the base plate 411 from interfering with the rotation of the module body 441.

[0042] In this embodiment, the module body 441 includes a main body 4411 and a connecting part 4412. A drive part 442 is telescopically mounted on the main body 4411. The connecting part 4412 is located between the main body 4411 and the drive part 442. Rotating shafts 443 are respectively provided on both sides of the connecting part 4412. Two rotating brackets 413 are provided on the base plate 411, located on both sides of the module body 441 and hinged to the two rotating shafts 443 respectively. The arrangement directions of the two rotating shafts 443 and the two rotating brackets 413 extend along the width direction of the base 1, and the two rotating brackets 413 are located on both sides of the clearance groove 45. In this way, the module body 441 can achieve stable rotation through the cooperation of the rotating shafts 443 and the rotating brackets 413, thereby further improving the clamping effect of the clamping plate 43.

[0043] In this embodiment, the second drive module 44 is a cylinder, the main body 4411 is the cylinder body, the drive part 442 is the piston rod of the cylinder, and the connecting part 4412 is disposed at the upper end of the cylinder body. A circular clearance opening 4413 is also provided on the connecting part 4412, and the clearance opening 4413 is concentrically arranged with the drive part 442. The drive part 442 is retractably inserted into the clearance opening 4413. The drive part 442 can extend along the clearance opening 4413 and drive the clamping plate 43 to rotate, preventing the connecting part 4412 from interfering with the extension and retraction of the drive part 442.

[0044] In this embodiment, the clamping seat 41 is provided with first protrusions 46 on both sides of its moving direction. The two first protrusions 46 are arranged along the width direction of the base 1 and are respectively connected to the two rotating frames 413. Buffer modules 47 are provided on both sides of the base 1 in the width direction. The two first protrusions 46 correspond one-to-one with the two buffer modules 47. Each buffer module 47 includes two opposing buffer pillars. The two buffer pillars are arranged along the moving direction of the clamping seat 41, and the first protrusions 46 are located between the two buffer pillars. Both buffer pillars are made of rubber material, and they can abut against the first protrusions 46 during the moving stroke of the clamping seat 41, thereby achieving movement buffering of the clamping seat 41 and preventing the clamping seat 41 from being damaged by rigid impact with the base 1.

[0045] In this embodiment, a positioning module 48 is also provided on one side of the base 1 in the width direction. The positioning module 48 is located near one of the buffer modules 47. It includes a positioning block 481 and two sensors 482 provided on the positioning block 481. Both sensors 482 are photoelectric sensors. The positioning block 481 extends along the moving direction of the clamping seat 41. The two sensors 482 are located at both ends of the positioning block 481 in the length direction. One of the two first protrusions 46 is provided with a sensing plate 49. The sensing plate 49 can pass through the two sensors 482 respectively during the movement of the clamping seat 41. During the movement of the clamping seat 41, the sensing plate 49 passes through the two sensors 482 respectively. The two sensors 482 can control the first drive module 42 to stop when the sensing plate 49 arrives, so that the clamping seat 41 stops at the corresponding position, so that the clamping assembly 4 can accurately clamp onto or away from the rotating workpiece.

[0046] In this embodiment, the weight-removing component 3 includes a first movable seat 31 translatably mounted on the base 1 along the width direction, a sixth drive module 32 for driving the first movable seat 31 to move, a second movable seat 33 translatably mounted on the first movable seat 31 along the length direction of the base 1, a seventh drive module 34 for driving the second movable seat 33 to move, an electric spindle 35 mounted on the second movable seat 33, and a drill bit 36 ​​rotatably mounted at the end of the electric spindle 35. The sixth drive module 32 and the seventh drive module 34 are both motor lead screw structures, and the drill bit 36 ​​is a tungsten carbide end mill, the length of which is the same as the length direction of the base 1.

[0047] The support assembly 2 includes a support base 21 and a support groove 22 formed on the support base 21. The support groove 22 extends along the width direction of the machine base 1. The drill bit 36 ​​is positioned toward the support base 21 and is able to perform weight removal processing on the rotating workpiece during its rotation.

[0048] A dust collection component 7 is also provided at the front end of the drill bit 36. The dust collection component 7 includes a hollow dust collection seat 71 and an air suction pipe 72 connected to the dust collection seat 71. The air suction pipe 72 is connected to an external fan. The dust collection seat 71 has a sliding hole and a dust collection port 73 on opposite sides. The sliding hole is set towards the drill bit 36, and the drill bit 36 ​​is slidably inserted into the sliding hole along its length.

[0049] Furthermore, the vacuuming assembly 7 also includes a vacuuming frame 74, with a vacuuming base 71 mounted on one end of the vacuuming frame 74. A guide rod 75 is provided at the other end of the vacuuming frame 74, the length of which is the same as the length of the drill bit 36. A stop block 76 is provided on the side of the electric spindle 35, and the guide rod 75 slidably passes through the stop block 76 along its length. An elastic element 77 is also sleeved on the guide rod 75, with both ends of the elastic element 77 connected to the vacuuming frame 74 and the stop block 76, respectively. The elastic element 77 is a spring.

[0050] As the second moving seat 33 drives the drill bit 36 ​​to move along the length of the machine base 1 and gradually approach the bearing assembly 2, the dust suction seat 71 located at the front end of the drill bit 36 ​​can first contact the rotating workpiece, and its dust suction port 73 presses against the surface of the rotating workpiece. Then the second moving seat 33 continues to move forward, and the dust suction seat 71 slides backward and compresses the spring under the squeezing action of the rotating workpiece. At this time, the drill bit 36 ​​gradually passes through the dust suction port 73 and abuts against the rotating workpiece. Then the drill bit 36 ​​rotates and performs weight removal processing on the rotating workpiece. At this time, the dust suction port 73 can abut against the rotating workpiece and suck out the generated debris, preventing debris from flying and causing damage to the physical and mental health of the workers.

[0051] In this embodiment, the dynamic balancing and weight-reducing mechanism further includes a corner assembly 5 disposed on one side of the base 1 in the width direction. The corner assembly 5 includes a corner seat 51 movably disposed along the direction close to or away from the bearing assembly 2, a third drive module (not shown in the figure) for driving the corner seat 51 to move, a gripper module 52 rotatable about its own axis and disposed on the corner seat 51, and a fourth drive module 53 for driving the gripper module 52 to rotate. A second protrusion 54 is disposed on one side of the corner seat 51, and a buffer 55 is disposed between the second protrusion 54 and the base 1. The moving direction of the corner seat 51 is the same as the width direction of the base 1. The third drive module is a lead screw and nut structure. The gripper module 52 is a three-jaw chuck, the rear end of which is connected to an external air source through a rotary joint, and its rotation axis extends along the width direction of the base 1. The fourth drive module 53 is a motor, which drives the gripper module 52 to rotate through a belt. The buffer 55 is a spring.

[0052] Furthermore, the dynamic balancing and weight-reducing mechanism also includes a push rod assembly 6 located on the other side of the base 1 in the width direction. The push rod assembly 6 is arranged opposite to the corner assembly 5 and includes a push rod frame 61, a push rod shaft 62 movable along the direction close to or away from the bearing assembly 2 and mounted on the push rod frame 61, and a fifth drive module 63 for driving the push rod shaft 62 to move. The axis of the push rod shaft 62 coincides with the center line of the gripper module 52. The direction of movement of the push rod shaft 62 is the same as the width direction of the base 1, and the fifth drive module 63 is a cylinder.

[0053] After machining one radial side of the rotating workpiece, the gripper module 52 approaches the bearing assembly 2 and clamps the rotating workpiece. Simultaneously, the push rod shaft 62 approaches the bearing assembly 2 and abuts against the end of the rotating workpiece. Then, the gripper module 52 drives the rotating workpiece to rotate, thereby relieving weight at different radial positions on the rotating workpiece. While the gripper module 52 rotates, the buffer 55 cushions the vibration of the corner seat 51, preventing damage to the rotating workpiece during rotation.

[0054] The implementation principle of a dynamic balancing and weight-reducing mechanism according to an embodiment of this application is as follows:

[0055] The rotating workpiece is placed in the bearing groove 22. The first drive module 42 and the second drive module 44 cooperate with each other and drive the clamping plate 43 to clamp onto the rotating workpiece. The third drive module drives the corner seat 51 to approach the rotating workpiece. The gripper module 52 clamps the end of the rotating workpiece. The fifth drive module 63 drives the push rod shaft 62 to abut against the other end of the rotating workpiece.

[0056] The first moving seat 31 and the second moving seat 33 cooperate with each other and drive the weight removal component 3 to dock with the bearing component 2. Then the drill bit 36 ​​performs weight removal processing on the rotating workpiece, and the dust collection component 7 absorbs the generated debris.

[0057] After processing, the drill bit 36 ​​disengages from the rotating workpiece, and the fourth drive module 53 drives the gripper module 52 to rotate. The gripper module 52 drives the rotating workpiece to rotate. After rotating through a set angle, the drill bit 36 ​​contacts the rotating workpiece again and performs weight removal processing on the rotating workpiece.

[0058] After all the positions of the rotating workpiece to be de-weighted are processed, the de-weighting component 3, the clamping component 4, the corner component 5 and the push rod component 6 are reset, and then the robot arm takes the rotating workpiece out of the bearing groove 22.

[0059] 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.
