Description

Technical Field

[0001] This application relates to the field of rotor de-weighting, and in particular to a multi-directional adjustable rotor de-weighting mechanism. Background Technology

[0002] The rotor is the rotating component in an electric motor. After it is manufactured, it needs to undergo dynamic balancing tests and weight reduction to eliminate the initial imbalance of the rotor.

[0003] However, existing de-weighting mechanisms can usually only perform de-weighting processing on fixed positions of rotors with fixed specifications, which greatly reduces the applicable scope of de-weighting mechanisms. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides a multi-directional adjustable rotor de-weighting mechanism with a wide range of applications.

[0005] The multi-directional adjustable rotor de-weighting mechanism provided in this application adopts the following technical solution:

[0006] A multi-directional adjustable rotor de-weighting mechanism includes a base on which a load-bearing component, a de-weighting component, and an adjusting component are disposed. The de-weighting component is movably disposed in the horizontal direction. The adjusting component is used to drive the de-weighting component to move. During its movement, the de-weighting component can approach and engage with the load-bearing component.

[0007] By adopting the above technical solution, the adjustment component can adjust the position of the de-weighting component, so that the de-weighting component can perform de-weighting processing on different positions of rotors of different specifications, effectively improving the applicability of the de-weighting mechanism.

[0008] In one specific implementation, the adjustment assembly includes a first adjustment seat disposed on the base and translatably movable along the X-axis, a first driving member for driving the first adjustment seat to move, a second adjustment seat disposed on the first adjustment seat and translatably movable along the Y-axis, a second driving member for driving the second adjustment seat to move, and the weight-reducing assembly is disposed on the second adjustment seat.

[0009] By adopting the above technical solution, the weight removal component can move along the X-axis and Y-axis directions with the cooperation of the first and second adjusting seats, which facilitates the weight removal component to perform precise weight removal processing on different positions of the rotor.

[0010] In one specific implementation, the weight-reducing component includes a mounting base, a spindle module disposed on the mounting base, and a rotatable drill bit disposed on the spindle module, the drill bit being positioned toward the load-bearing component.

[0011] By adopting the above technical solution, the drill bit can quickly and accurately remove weight from the rotor under the drive of the spindle module, effectively improving the weight removal accuracy and quality of the rotor.

[0012] In one specific implementation, the rotor weight removal mechanism further includes a dust collection assembly, which includes a hollow dust collection seat and a suction pipe connected to the dust collection seat. The dust collection seat has sliding holes and dust collection ports on opposite sides, with the sliding holes facing the drill bit and the drill bit slidably passing through the sliding holes along its length.

[0013] By adopting the above technical solution, when the drill bit is removing weight from the rotor, the dust suction port can come into contact with the rotor and suck out the generated debris, preventing debris from flying and causing damage to the physical and mental health of the workers.

[0014] In one specific implementation, the vacuuming assembly further includes a vacuuming frame, with the vacuuming seat mounted at one end of the vacuuming frame. The other end of the vacuuming frame is provided with a guide rod, the length direction of which is the same as the length direction of the drill bit. A stop is provided on the side of the mounting seat, and the guide rod is slidably inserted through the stop along its length direction. An elastic element is also sleeved on the guide rod, with both ends of the elastic element connected to the vacuuming frame and the stop, respectively.

[0015] By adopting the above technical solution, the suction port can be pressed against the rotor under the action of the elastic element, which effectively improves the suction effect of the suction assembly.

[0016] In one specific implementation, the rotor de-weighting mechanism further includes a clamping assembly disposed on the base. The clamping assembly includes a rotating seat, a clamping plate movably disposed on the rotating seat, and a third driving member for driving the clamping plate to move. The clamping plate has a clamping end, which can clamp onto the bearing assembly during the movement of the clamping plate.

[0017] By adopting the above technical solution, the clamping plate can clamp onto the rotor during its operation, thereby preventing the rotor from shifting during the weight removal process and effectively improving the weight removal accuracy of the rotor.

[0018] In one specific implementation, the clamping assembly further includes a transmission module, which includes a first link, a second link, and a third link. The first link and the second link are arranged along the direction from the clamping plate to the bearing assembly. The two ends of the first link are respectively hinged to the output end of the clamping plate and the third drive member. The two ends of the second link are respectively hinged to the clamping plate and the rotating seat. The two ends of the third link are respectively hinged to the output end of the third drive member and the second link.

[0019] By adopting the above technical solution, the clamping plate can be stably and accurately clamped onto the rotor under the drive of the transmission module, effectively improving the clamping strength of the clamping assembly.

[0020] In one specific implementation, the rotor de-weighting mechanism further includes a corner assembly disposed on the base. The corner assembly includes a corner seat, a gripper module rotatable about its own axis and disposed on the corner seat, and a fourth driving member for driving the gripper module to rotate. The gripper module is disposed facing the bearing assembly.

[0021] By adopting the above technical solution, the gripper module can drive the rotor to rotate during the weight removal process, so as to remove weight at different positions in the radial direction of the rotor.

[0022] In one specific implementation, the corner bracket is movably configured in a direction toward or away from the support assembly, and the corner assembly further includes a fifth drive member for driving the corner bracket to move.

[0023] By adopting the above technical solution, the corner assembly can clamp and rotate rotors of different lengths during the movement of the corner seat, further improving the applicability of the weight-removing mechanism.

[0024] In one specific implementation, the rotor de-weighting 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 sixth driving member for driving the push rod shaft to move. The axis of the push rod shaft coincides with the center line of the gripper module.

[0025] By adopting the above technical solution, the push rod shaft can abut against the end of the rotor during movement, effectively improving the rotational stability of the rotor.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] The adjustment component can adjust the position of the de-weighting component, so that the de-weighting component can perform de-weighting processing on different positions of rotors of different specifications, effectively improving the applicability of the de-weighting mechanism.

[0039] 100. Rotor. Detailed Implementation

[0040] The present application will be further described in detail below with reference to the accompanying drawings.

[0041] See Figure 1-2 As shown, a multi-directional adjustable rotor de-weighting mechanism includes a base 1, on which a bearing assembly 2, a de-weighting assembly 3, and an adjusting assembly 4 are mounted. The bearing assembly 2 and the de-weighting assembly 3 are arranged along the length of the base 1. The de-weighting assembly 3 is movably positioned horizontally. The adjusting assembly 4 drives the de-weighting assembly 3 to move, allowing it to approach and engage with the bearing assembly 2 during its movement. In this way, when de-weighting the rotor 100, the adjusting assembly 4 can adjust the position of the de-weighting assembly 3, enabling it to de-weight different positions on rotors 100 of different specifications, effectively improving the applicability of the de-weighting mechanism.

[0042] In this embodiment, the adjustment assembly 4 includes a first adjustment seat 41 movably mounted on the base 1 along the X-axis, a first driving member 42 for driving the first adjustment seat 41 to move, a second adjustment seat 43 movably mounted on the first adjustment seat 41 along the Y-axis, and a second driving member 44 for driving the second adjustment seat 43 to move. The weight-reducing assembly 3 is mounted on the second adjustment seat 43. The X-axis direction is the same as the width direction of the base 1, and the Y-axis direction is the same as the length direction of the base 1. Both the first driving member 42 and the second driving member 44 are motor lead screw structures.

[0043] During weight removal, the weight removal component 3 can move along the X-axis and Y-axis directions with the cooperation of the first adjusting seat 41 and the second adjusting seat 43, facilitating precise weight removal processing at different positions of rotors 100 with different diameters. Specifically, the first adjusting seat 41 can drive the weight removal component 3 to move along the X-axis direction to perform weight removal processing at different positions of the rotor 100 in the axial direction, and the second adjusting seat 43 can drive the drive component to move along the Y-axis direction to perform weight removal processing on rotors 100 with different diameters.

[0044] In this embodiment, the weight-removing component 3 includes a mounting base 31, a spindle module 32 mounted on the mounting base 31, and a rotatable drill bit 33 mounted on the spindle module 32. The drill bit 33 is oriented towards the bearing component 2, and its length direction is the same as the length direction of the machine base 1. The spindle module 32 is an electric spindle that drives the drill bit 33 to rotate. The drill bit 33 is a tungsten carbide end mill. Driven by the spindle module 32, the drill bit 33 can quickly and accurately remove weight from the rotor 100, effectively improving the weight-removing accuracy and quality of the rotor 100.

[0045] In this embodiment, the rotor weight removal mechanism further includes a dust collection assembly 5, which includes a hollow dust collection seat 51 and an air suction pipe 52 connected to the dust collection seat 51. The dust collection seat 51 is located at the front end of the drill bit 33, and the air suction pipe 52 is connected to an external exhaust fan. Sliding holes 53 and dust suction ports 54 are respectively provided on opposite sides of the dust collection seat 51. The sliding holes 53 are positioned facing the drill bit 33, and the drill bit 33 is slidably inserted into the sliding holes 53 along its length.

[0046] Furthermore, the vacuuming assembly 5 also includes a vacuuming frame 55, a vacuuming base 51 mounted on the front end of the vacuuming frame 55, and a guide rod 56 at the rear end of the vacuuming frame 55. The length direction of the guide rod 56 is the same as the length direction of the drill bit 33. A stop block 34 is provided on the side of the mounting base 31. The guide rod 56 is slidably inserted into the stop block 34 along its length direction. An elastic element 57 is also sleeved on the guide rod 56. The two ends of the elastic element 57 are connected to the vacuuming frame 55 and the stop block 34, respectively. The elastic element 57 is a spring.

[0047] As the second adjusting seat 43 drives the drill bit 33 to move along the Y-axis and gradually approach the bearing assembly 2, the dust suction seat 51 located at the front end of the drill bit 33 can first contact the rotor 100, and its dust suction port 54 presses against the surface of the rotor 100. Then the second adjusting seat 43 continues to move forward, and the dust suction seat 51 slides backward and compresses the spring under the squeezing action of the rotor 100. At this time, the drill bit 33 gradually passes through the dust suction port 54 and touches the rotor 100. Then the drill bit 33 rotates and performs weight removal processing on the rotor 100. At this time, the dust suction port 54 can touch the rotor 100 and suck out the generated debris, preventing debris from flying and causing damage to the physical and mental health of workers.

[0048] In this embodiment, the support component 2 includes a base 21, a support block 22 disposed on the base 21, and a support groove 23 formed on the support block 22. The support groove 23 extends along the width direction of the base 1, and the rotor 100 can be placed in the support groove 23 along its axial direction.

[0049] In this embodiment, the rotor de-weighting mechanism further includes a clamping assembly 6 mounted on the base 1. The clamping assembly 6 is located on the side of the bearing assembly 2 away from the de-weighting assembly 3. It includes a mounting plate 66 mounted on the base 21, a rotating seat 61 mounted on the mounting plate 66, a clamping plate 62 movably mounted on the rotating seat 61, and a third driving member 63 for driving the clamping plate 62. The clamping plate 62 has a clamping end 64, which can clamp onto the bearing assembly 2 during the movement of the clamping plate 62. The third driving member 63 is a cylinder.

[0050] Furthermore, the clamping assembly 6 also includes a transmission module 65, which includes a first connecting rod 651, a second connecting rod 652, and a third connecting rod 653. The first connecting rod 651 and the second connecting rod 652 are arranged along the direction from the clamping plate 62 to the bearing assembly 2. The two ends of the first connecting rod 651 are hinged to the output ends of the clamping plate 62 and the third driving member 63, respectively. The two ends of the second connecting rod 652 are hinged to the clamping plate 62 and the rotating seat 61, respectively. The two ends of the third connecting rod 653 are hinged to the output end of the third driving member 63 and the second connecting rod 652, respectively. There are two of each of the first connecting rod 651, the second connecting rod 652, and the third connecting rod 653, which are respectively located on opposite sides of the clamping plate 62.

[0051] The rotation axes between the first connecting rod 651 and the clamping plate 62, the rotation axis between the first connecting rod 651 and the output end of the third driving member 63, the rotation axis between the second connecting rod 652 and the clamping plate 62, the rotation axis between the second connecting rod 652 and the rotating seat 61, the rotation axis between the third connecting rod 653 and the output end of the third driving member 63, and the rotation axis between the third connecting rod 653 and the second connecting rod 652 are parallel to each other and all extend along the width direction of the base 1. After the rotor 100 is supported on the bearing assembly 2, the output end of the third driving member 63 extends upward and drives the first connecting rod 651 to move upward. During its upward movement, the first connecting rod 651 pushes the rear end of the clamping plate 62 to lift upward. During the upward movement, the clamping plate 62 drives the second connecting rod 652 to rotate and moves forward under the limit of the second connecting rod 652. After the clamping plate 62 moves into place, its front end can clamp onto the rotor 100 to prevent the rotor 100 from shifting during the weight removal process, effectively improving the weight removal accuracy of the rotor 100.

[0052] In this embodiment, the rotor de-weighting mechanism further includes a corner assembly 7 mounted on the base 1. The corner assembly 7 is located at one end of the bearing groove 23 along its length and includes a corner seat 71, a gripper module 72 rotatable about its own axis and mounted on the corner seat 71, and a fourth driving member 73 for driving the gripper module 72 to rotate. The gripper module 72 is positioned facing the bearing assembly 2. The rotation axis of the gripper module 72 extends along the width of the base 1. The fourth driving member 73 is a motor that drives the gripper module 72 to rotate via gear transmission. The gripper module 72 is a three-jaw chuck, and its rear end is connected to an external air source via a rotary joint. The gripper module 72 can clamp the rotor 100 and drive it to rotate during the de-weighting process, enabling the de-weighting assembly 3 to de-weight different positions on the rotor 100 in the radial direction.

[0053] Furthermore, the corner bracket 71 is movably configured to move towards or away from the load-bearing assembly 2, and the corner assembly 7 also includes a fifth drive member 74 for driving the corner bracket 71 to move. The fifth drive member 74 includes a lead screw and an adjusting screw located at the end of the lead screw. When dealing with rotors 100 of different lengths, the worker can rotate the adjusting screw to move the corner bracket 71, thereby further improving the applicability of the weight-relief mechanism.

[0054] In this embodiment, the rotor weight-removing mechanism further includes a push rod assembly 8 mounted on the base 1. The push rod assembly 8 is disposed opposite to the corner assembly 7 and includes a push rod frame 81 mounted on the base 21, a push rod shaft 82 movable along the direction of approaching or moving away from the bearing assembly 2 and mounted on the push rod frame 81, and a sixth driving member 83 for driving the push rod shaft 82 to move. The axis of the push rod shaft 82 coincides with the center line of the gripper module 72. The sixth driving member 83 is a cylinder, and the push rod shaft 82 can abut against the end of the rotor 100 during movement, effectively improving the rotational stability of the rotor 100.

[0055] The implementation principle of a rotor weight-removing mechanism according to an embodiment of this application is as follows:

[0056] The rotor 100 is placed in the bearing groove 23. The third driving member 63 drives the clamping rod to move and clamp onto the rotor 100. The fifth driving member 74 drives the corner seat 71 to approach the rotor 100. The gripper module 72 clamps the end of the rotor 100. The sixth driving member 83 drives the push rod shaft 82 to abut against the other end of the rotor 100.

[0057] The first adjusting seat 41 and the second adjusting seat 43 cooperate with each other and drive the weight removal component 3 to dock with the bearing component 2. Then the drill bit 33 performs weight removal processing on the rotor 100, and the dust collection component 5 absorbs the generated debris.

[0058] After processing, the drill bit 33 disengages from the rotor 100, and the fourth drive component 73 drives the gripper module 72 to rotate. The gripper module 72 drives the rotor 100 to rotate. After rotating through a set angle, the drill bit 33 comes into contact with the rotor 100 again and performs weight removal processing on the rotor 100.

[0059] After all the positions of the rotor 100 to be deweighted are processed, the deweighting component 3, the clamping component 6, the corner component 7 and the push rod component 8 are reset, and then the robot arm takes the rotor 100 out of the bearing groove 23.

[0060] 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.
