Description

Technical Field

[0001] This invention relates to the field of flywheel machining tooling technology, specifically to a flywheel machining tooling and method in a new energy flywheel energy storage system. Background Technology

[0002] The flywheel is the core component of a flywheel energy storage system. Its function is to increase the rotor's limiting angular velocity, reduce rotor weight, and maximize the energy storage capacity of the flywheel energy storage system. It is mostly made of carbon fiber materials. The performance of the bearing system directly affects the reliability, efficiency, and lifespan of the flywheel energy storage system. Most flywheel energy storage systems use magnetic levitation systems to reduce friction during motor rotor rotation, reduce mechanical losses, and improve energy storage efficiency.

[0003] While conventional surface treatment fixtures for flywheel machining can perform operations such as grinding on the flywheel surface, they typically only clamp and position the flywheel. For example, Chinese utility model patent CN209319718U provides a special machining table for flywheel surface structures, which only uses an arc-shaped block connected to a screw to clamp the flywheel to be processed. This makes it difficult for the clamping structure to guarantee the stability of the flywheel during the processing, resulting in flywheel force deviation and thus affecting the surface treatment effect of the flywheel.

Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] Example 1 refer to Figures 1-6 This invention provides a flywheel machining fixture for a new energy flywheel energy storage system, used for surface machining of the flywheel body 1 in the new energy flywheel energy storage system, including a machining base, and further comprising: The outer clamping unit is used to clamp the side wall of the flywheel body 1 placed on the machining base in the direction of the axis towards the flywheel body 1; The flywheel body 1 has a shaft hole 2 along its axial direction.

[0024] The inner positioning unit is used to support and position the inner wall of the shaft hole 2 of the flywheel body 1 towards the circumferential side wall of the flywheel body 1. A machining component is used to machine the upper surface of the flywheel body 1, which is clamped and positioned.

[0025] Specifically, the processing base includes a base box 5, a processing table 3, and an arched frame 4 connected sequentially from bottom to top; The arched frame 4 is fitted on the outside of the processing table 3. The fixed end of the outer clamping unit is connected to the base box 5. The output end of the outer clamping unit extends through the processing table 3 into the arched frame 4. The inner positioning unit is set on the upper surface of the processing table 3. The output end of the outer clamping unit is fitted on the outside of the inner positioning unit.

[0026] The connecting end of the processing component is movably connected to the arched frame 4. The processing end of the processing component is located above the processing table 3, which facilitates the adjustment of the processing position according to the requirements, and can also adapt to different thicknesses or different processing amounts.

[0027] By distributing the outer clamping units and processing components vertically, the horizontal dimensions of the tooling are reduced, thus lowering the processing area required.

[0028] To further explain, the outer clamping unit includes a clamping drive and multiple first clamping plates 14. The multiple first clamping plates 14 are arranged in a circumferential array around the axis of the processing table 3. The multiple first clamping plates 14 are all slidably connected to the processing table 3 through the clamping drive. The sliding direction of the first clamping plates 14 is all towards the axis of the processing table 3, so that all the first clamping plates 14 can move towards or away from the axis of the processing table 3 under the control of the clamping drive, thereby realizing the clamping and releasing of flywheel bodies 1 of different specifications.

[0029] The angle between the first clamping plate 14 and the processing table 3 can be matched with the angle between the outer side wall of the flywheel body 1 and the vertical direction, thereby increasing the contact area between the first clamping plate 14 and the outer side wall of the flywheel body 1, improving clamping reliability, and adapting to the clamping requirements of different types of flywheel bodies 1.

[0030] The inner positioning unit is coaxially arranged with the processing table 3. It is used to determine the position of the flywheel body 1 on the processing table 3 and to limit the position of the flywheel body 1 radially from inside the flywheel body 1, so as to achieve stable clamping of the flywheel body 1.

[0031] Specifically, the clamping drive includes a first servo motor 6, a first reducer 7, a first lead screw 8, multiple connecting rods 11, and multiple moving blocks 13; multiple limiting sliding holes 12 are provided on the processing table 3; the number of limiting sliding holes 12, moving blocks 13, connecting rods 11, and first clamping plates 14 are all the same and are set one-to-one.

[0032] The fixed end of the first servo motor 6 is connected to the base housing 5. The output end of the first servo motor 6 passes through the bottom of the base housing 5 and is connected to the bottom end of the first lead screw 8 through the first reducer 7. The first reducer 7 is a transmission device for low speed and high torque. The power of the first servo motor 6 running at high speed is reduced by the meshing of the gear with fewer teeth on the shaft of the first reducer 7 with the large gear on the output shaft.

[0033] The first lead screw 8 is coaxially arranged with the processing table 3, and a limit plate 10 is provided on the top of the first lead screw 8. At this time, multiple connecting rods 11 are arranged in a circumferential array around the axis of the first lead screw 8. One end of each connecting rod 11 is threadedly connected to the first lead screw 8 through a first movable sleeve 9. The first movable sleeve 9 is located between the limit plate 10 and the first reducer 7. The other end of the connecting rod 11 is hinged to the corresponding movable block 13. The movable block 13 is slidably connected to the corresponding limit sliding hole 12 along its length direction. The bottom of the first clamping plate 14 is connected to the top of the corresponding movable block 13.

[0034] Working process: When clamping the side wall of the flywheel body 1 placed on the machining base in the direction of the axis of the flywheel body 1: The first servo motor 6 drives the first lead screw 8 to rotate through the first reducer 7, and the first moving sleeve 9 moves downwards in sync, away from the limiting plate 10; the bottom end of the first lead screw 8 is offset downwards under the drive of the first moving sleeve 9, and the top end of the first lead screw 8 drives the moving block 13 to move towards the inner positioning unit under the limitation of the limiting sliding hole 12; at the same time, the moving block 13 drives the first clamping plate 14 to approach the outer wall of the flywheel body 1 until it contacts the outer wall of the flywheel body 1, so as to achieve the initial clamping and positioning of the flywheel body 1.

[0035] To further explain, the inner positioning unit includes a positioning sleeve 15, a positioning drive, and multiple second clamping plates 17. The positioning sleeve 15 is coaxially arranged with the machining table 3 and connected to the upper surface of the machining table 3. The fixed end of the positioning drive is connected to the machining table 3, and the output end of the positioning drive extends into the positioning sleeve 15 to drive the second clamping plates 17. The multiple second clamping plates 17 are arranged in a circumferential array around the axis of the positioning sleeve 15 to position the shaft hole 2 by pressing it from multiple directions and to cooperate with the first clamping plate 14 to stably clamp the flywheel body 1.

[0036] The positioning sleeve 15 has multiple first strip-shaped limiting holes 16 along its radial direction. The positioning sleeve 15 connects its inner and outer sides through the first strip-shaped limiting holes 16. The number of first strip-shaped limiting holes 16 is the same as the number of second clamping plates 17 and they are set one-to-one. One end of the second clamping plate 17 is connected to the output end of the positioning drive. The other end of the second clamping plate 17 passes through the corresponding first strip-shaped limiting hole 16 and extends to the outer side of the positioning sleeve 15. During processing, it faces the inner wall of the shaft hole 2. The positioning drive is used to simultaneously drive the second clamping plate 17 to expand outward along the radial direction of the positioning sleeve 15 and press against the shaft hole 2. While positioning the flywheel body 1, it further clamps and fixes the flywheel body 1, improving the stability of the flywheel body 1.

[0037] Specifically, the positioning drive includes a first electric push rod 21, a guide block 23, and multiple push plates 20.

[0038] The first electric push rod 21 is located below the processing table 3. A through hole 22 is provided on the processing table 3 along its thickness direction. The positioning sleeve 15 is coaxial with the through hole 22. The output end of the first electric push rod 21 extends through the through hole 22 on the processing table 3 into the positioning sleeve 15. The bottom of one end of the second clamping plate 17 is connected to the push plate 20. The push plate 20 is vertically set and extends to the bottom of the first strip-shaped limiting hole 16. The guide block 23 has a frustum structure. The bottom surface of the guide block 23 is connected to the output end of the first electric push rod 21. The inclined side of the guide block 23 contacts the bottom of the push plate 20.

[0039] Work process: The inner wall of the shaft hole 2 of the flywheel body 1 is supported and positioned towards the circumferential side wall of the flywheel body 1: The first electric push rod 21 pushes the guide block 23 upward, and the outer wall of the guide block 23 contacts the push plate 20; the guide block 23 continues to move upward, and the inclined side of the guide block 23 drives the push plate 20 to move outward in the horizontal direction until the second clamping plate 17 presses against the inner wall of the shaft hole 2.

[0040] refer to Figure 4In order to automatically retract the second clamping plate 17 when the flywheel body 1 is disassembled after processing, it is preferable that a fixing rod 18 is provided in the positioning sleeve 15 along its axial direction, and a return spring 19 is provided between the fixing rod 18 and the corresponding second clamping plate 17. The fixing rod 18 is located directly above the guide block 23. When the first electric push rod 21 retracts downward, the guide block 23 disengages from the push plate 20, and the push plate 20 moves close to the fixing rod 18 under the traction of the return spring 19, so as to avoid interference when the flywheel body 1 is disassembled.

[0041] Further specifying, the processing components include a vertical adjustment and rotation mechanism, a horizontal adjustment mechanism, and a processing mechanism.

[0042] The machining mechanism is used to perform machining, such as grinding, on the upper surface of the flywheel body 1. The machining mechanism is connected to the output end of the vertical adjustment and rotation mechanism through the horizontal adjustment mechanism. The fixed end of the vertical adjustment and rotation mechanism is connected to the top of the arch frame 4. The output end of the vertical adjustment and rotation mechanism is coaxially set with the machining table 3. The vertical adjustment and rotation mechanism can drive the horizontal adjustment mechanism to move up and down in the vertical direction, and can also drive the horizontal adjustment mechanism to rotate around its axis, so as to drive the machining mechanism to perform machining in different directions on the upper surface of the flywheel body 1. The horizontal adjustment mechanism is used to drive the machining mechanism to perform machining in the radial direction of the flywheel body 1. The vertical adjustment and rotation mechanism can also be adjusted up and down, and the machining feed of the machining mechanism can be controlled by the horizontal adjustment mechanism.

[0043] Specifically, the vertical adjustment and rotation mechanism includes a second electric push rod 24, a lifting plate 25, a limit rod 26, a second servo motor 29, and a second reducer 30.

[0044] The top of the arched frame 4 has limit holes 27, and four holes are used as an example for explanation. The lifting plate 25 is located below the limit holes 27, that is, inside the arched frame 4. The second electric push rod 24 is set at the top of the arched frame 4. The output end of the second electric push rod 24 passes through the top of the arched frame 4 and is connected to the lifting plate 25 for lifting. The top of the limit rod 26 is located above the arched frame 4. The bottom end of the limit rod 26 passes through the limit hole 27 and is connected to the lifting plate 25. The limit rod 26 is used to limit the horizontal displacement of the lifting plate 25 when it moves up and down, so as to ensure the stability of its lifting process.

[0045] The second servo motor 29 is connected to the bottom of the lifting plate 25 via the first motor frame 28. The output end of the second servo motor 29 is coaxially set with the processing table 3. The output end of the second servo motor 29 is connected to the horizontal adjustment mechanism, which is used to drive the horizontal adjustment mechanism to rotate around the axis of the processing table 3 and adjust the processing mechanism to process in different radial directions of the flywheel body 1.

[0046] To further explain, the lateral adjustment mechanism includes a movable base 31, a second lead screw 33, and a third servo motor 32; the machining mechanism includes a fourth servo motor 39, a second movable sleeve 34, a limiting slide plate 35, a movable plate 37, and a cutter head connecting seat 40.

[0047] The movable base 31 is arranged horizontally. The output end of the second servo motor 29 is connected to one end of the movable base 31, and the other end of the movable base 31 is connected to the third servo motor 32. The second lead screw 33 is arranged horizontally inside the movable base 31. The output end of the third servo motor 32 is connected to one end of the second lead screw 33, and the other end of the second lead screw 33 is rotatably connected to the movable base 31, so that the third servo motor 32 can control the rotation of the second lead screw 33.

[0048] The bottom of the movable base 31 is provided with a second strip-shaped limiting hole 36 along the length direction of the second lead screw 33. The second movable sleeve 34 is sleeved on the second lead screw 33 and threadedly connected to the second lead screw 33. The second movable sleeve 34 is connected to the movable plate 37 through the limiting slide plate 35. The movable plate 37 is located below the second strip-shaped limiting hole 36. The limiting slide plate 35 is slidably connected to the second strip-shaped limiting hole 36, so that when the second lead screw 33 rotates, the second movable sleeve 34 can reciprocate along the length direction of the second strip-shaped limiting hole 36. The fourth servo motor 39 is connected to the movable plate 37 through the second motor frame 38, so that the second lead screw 33 can drive the fourth servo motor 39 to reciprocate in the horizontal direction. The output end of the fourth servo motor 39 passes through the second motor frame 38 and is connected to the cutter head connecting seat 40 for machining the surface of the flywheel body 1.

[0049] When the fourth servo motor 39 is running, it can drive the grinding head 41 to rotate at high speed through the tool head connecting seat 40. When the second electric push rod 24 is running, it can drive the grinding head 41 to rise and fall to perform feed motion. When the third servo motor 32 is running, it can drive the grinding head 41 to move back and forth along the radial direction of the flywheel body 1 for processing.

[0050] It should be noted that the machining fixture is electrically connected to an external controller and 220V AC mains power. The controller can be an existing technology device such as a computer. In this invention, the precise control principle of the first electric push rod 21 and the second electric push rod 24 is to achieve motion conversion through the mechanical cooperation of the servo motor and the lead screw. The status is monitored in real time with the help of encoders and other devices. Finally, the controller dynamically adjusts the output according to the deviation, thereby achieving precise control of position, speed and force within the millimeter or even micrometer range. Moreover, the precise control principle of the first servo motor 6 driving the first clamping plate 14 to move, the precise control principle of the second servo motor 29 running to control the rotation angle of the grinding head 41, and the precise control principle of the third servo motor 32 running to control the position adjustment of the grinding head 41 are all achieved by using encoders, limit switches and other devices to monitor the status in real time. Finally, the controller dynamically adjusts the output according to the deviation, thereby achieving precise control of position, speed and force within the millimeter or even micrometer range.
