Description

Technical Field

[0001] The present invention relates to the field of concentricity adjustment of a magnetic levitation machine head, and particularly to an installation method for installing a magnetic levitation machine head onto an eccentric tooling. Background Art

[0002] The magnetic levitation blower is a new type of highly efficient energy-saving and environmental protection product that applies active magnetic levitation bearing technology and high-speed permanent magnet synchronous motor technology on the basis of traditional blowers and is integrally designed.

[0003] The active magnetic levitation bearing system is the core system of the magnetic levitation blower. The motor rotor is fixed between two radial magnetic bearings and two axial magnetic bearings. The position of the rotor is detected by a position sensor, and the position signal is fed back to the magnetic bearing controller in real time. When the rotor deviates, the controller adjusts the magnetic field force of each degree of freedom of the magnetic bearing according to the deviation amount of the rotor to return the rotor to the correct position.

[0004] Chinese Patent Application for Invention (Publication No. CN113669273A, Publication Date: November 19, 2021) discloses a magnetic levitation centrifuge blower, including a main shaft, a front radial magnetic bearing, a front bearing seat, a rear radial magnetic bearing, a rear bearing seat, a motor, and a backup bearing; wherein, there are two groups of backup bearings which are respectively inserted at the left and right ends of the main shaft. The front radial magnetic bearing is inserted at the left end of the main shaft and is located on the right side of the left backup bearing. The rear radial magnetic bearing is inserted at the right end of the main shaft and is located on the left side of the right backup bearing. The front bearing seat is sleeved on the left end of the main shaft and wraps the backup bearing and the front radial magnetic bearing on the left side of the main shaft. The rear bearing seat is sleeved on the right end of the main shaft and wraps the backup bearing and the rear radial magnetic bearing on the right side of the main shaft. The motor is sleeved in the middle of the main shaft and its left and right ends respectively abut against the front bearing seat and the rear bearing seat.

[0005] The existing method for adjusting the concentricity of the machine head is to adjust only the concentricity among the front bearing seat, the rear bearing seat, and the motor when the main shaft has not been installed into the machine head. However, after the main shaft is installed into the machine head, the machine head will also be eccentric with respect to the main shaft, which affects the normal operation of the main shaft and the subsequent machining accuracy of the equipment. Summary of the Invention

[0006] In order to solve the above technical problems, the purpose of the present invention is to provide an installation method for installing a magnetic levitation machine head onto an eccentric tooling.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0039] At the same time, it should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0040] The following will make a detailed description of the specific embodiments of the present invention with reference to the drawings.

[0041] As Figures 1 to 6 shown, the eccentric tooling 2 for adjusting the magnetic levitation head 1 includes a tooling table 21 and two adjusting tooling frames 22. Setting two adjusting tooling frames 22 can better fix and adjust the eccentricity of the head 1. The adjusting tooling frame 22 includes a fixing ring 24 and a connecting rod 25. The fixing ring 24 is integrally provided in the middle of the connecting rod 25, and the diameter setting direction of the fixing ring 24 is the same as the length setting direction of the connecting rod 25, ensuring that the fixing ring 24 and the connecting rod 25 are in the same vertical plane. Among them, 9 circumferentially distributed fixing holes 26 are provided on the outer diameter of the fixing ring 24, and the distance angle between each fixing hole 26 is 30°.

[0042] The adjusting tooling frame 22 is respectively provided with a through bolt hole at the left and right ends of the connecting rod 25, and 2 - 4 slide rails 23 are provided on the tooling table 21. Among them, the slide rails 23 communicate with both ends of the tooling table 21. It includes an inner cavity 231 and a chute 232. The inner cavity 231 is provided inside the tooling table 21, and the chute 232 communicates with the inner cavity 231. The width of the inner cavity 231 is greater than the width of the chute 232, so that the cross-sectional shape of the slide rail 23 is "convex". Before the adjusting tooling frame 22 is slidably connected to the tooling table 21, first place the table bolt in the slide rail 23, then let it pass through the threaded hole and use a nut or an annular backing plate to connect the tooling table 21 and the adjusting tooling frame 22 together. At this time, the adjusting tooling frame 22 can make a sliding movement on the tooling table 21 through the table bolt. The specific connection structure is that the bolt head of the table bolt is located in the inner cavity 231, the screw rod of the table bolt is located in and protrudes from the chute 232, and the connecting rod 25 is inserted on the screw rod through the bolt hole, and an annular backing plate for fixing the connecting rod is provided at the bolt tail of the table bolt, so as to drive the connecting rod 25 to make a sliding movement on the slide rail 23 through the table bolt.

[0043] AsFigure 2 As shown in the figure, a main shaft 11, a front radial magnetic bearing 12, a front bearing seat 13, a rear radial magnetic bearing 14, a rear bearing seat 15, a motor 16 and an emergency landing bearing 17 are provided inside the maglev machine head 1; among them, there are two groups of emergency landing bearings 17 which are respectively inserted at the left and right ends of the main shaft 11. The front radial magnetic bearing 12 is inserted at the left end of the main shaft 11 and is located on the right side of the left emergency landing bearing 17. The rear radial magnetic bearing 14 is inserted at the right end of the main shaft 11 and is located on the left side of the right emergency landing bearing 17. The front bearing seat 13 is sleeved on the left end of the main shaft 11 and wraps the emergency landing bearing 17 and the front radial magnetic bearing 12 on the left side of the main shaft 11. The rear bearing seat 15 is sleeved on the right end of the main shaft 11 and wraps the emergency landing bearing 17 and the rear radial magnetic bearing 14 on the right side of the main shaft 11. The motor 16 is sleeved in the middle of the main shaft 11 and its left and right ends respectively abut against the front bearing seat 13 and the rear bearing seat 15. Among them, motor feet 4 connected by bolts are provided at both ends of the outer diameter of the machine head 1. Setting two motor feet 4 can better fix the machine head 1 on the eccentric tooling 2, and setting two motor feet 4 ensures the stability of the machine head 1 and makes it not easy to deflect.

[0044] Among them, 4 slide rails 23 are provided on the workbench. The slide rails 23 near the left and right sides are provided for the adjustment tooling frame 22 to perform sliding movement; the 2 slide rails 23 near the inner side are provided for the motor feet 4 to perform sliding movement.

[0045] In order to measure the eccentricity of the maglev machine head 1, it is necessary to first install the tooling table 21 on the three-coordinate platform 3, and then sequentially slide a set of adjustment tooling frames 22, motor feet 4 and a set of adjustment tooling frames 22 into the slide rails 23, and use bench bolts to fix the motor feet 4 on the tooling table 21; then slide the adjustment tooling frame 22 again so that the first threaded hole and the second threaded hole are fixed below the corresponding fixing holes 26. Such setting of the adjustment tooling frame 22 is to facilitate the adjustment of the eccentricity of the machine head 1 later. The first threaded hole and the second threaded hole here are respectively provided on the outer diameter of the front bearing seat 13 and the outer diameter of the rear bearing seat 15. Among them, the subsequent eccentricity and concentricity have the same meaning.

[0046] Immediately afterwards, use a three-coordinate probe to collect two horizontal points on the left side plane of the front bearing seat 13 and align the plane of the machine head 1 with the Y axis of the three-coordinate. After the alignment is completed, use a three-coordinate probe to collect the outer circle H of the right end plane of the rear bearing seat 15 and establish the origin of the coordinate system of the machine head 1. By comparing the origin of the coordinate system with the Y-axis alignment, the concentricity of the machine head 1 is determined. At this time, if the concentricity (eccentricity) compared is within the specified range, that is, the four clearances between the main shaft 11 and both ends are within the specified range and will not affect the normal operation of the main shaft 11, then no subsequent operations need to be performed at this time, and the machine head 1 and the motor feet 4 can be directly removed from the eccentric tooling 2.

[0047] When the concentricity is not within the specified range, use a three-coordinate probe to collect the outer circle G of the left end plane of the front bearing housing 13, and evaluate the eccentricity of the outer circle G of the front bearing housing 13 relative to the X-axis and Z-axis with the origin of the coordinate system of the machine head 1. According to the obtained eccentricity values of the X-axis and Z-axis, loosen the lock nut provided at the left end of the front bearing housing 13, set an inner hexagon bolt on the fixing hole 26 of the adjusting tooling frame 22 at the left end of the front bearing housing 13, screw the inner hexagon bolt into the first threaded hole of the front bearing housing 13, and cooperate with the annular cushion plate and the cross-section 27 to displace the front bearing housing 13; this displacement is to adjust the eccentricity of the front bearing housing 13 relative to the origin of the coordinate system of the machine head 1 on the Z-axis and X-axis.

[0048] Among them, on the outer diameter surface of the fixing ring 24, there is a cross-section 27 arranged axially, the cutting direction of the cross-section 27 is perpendicular to the setting direction of the fixing hole 26, and the cutting depth of the cross-section 27 on the outer diameter of the fixing ring 24 is 6 mm - 8 mm. By arranging the cross-section 27 at each fixing hole 26 of the fixing ring 24, the contact area between the inner hexagon bolt and the fixing ring 24 can be increased, and setting an annular cushion plate between the inner hexagon bolt and the fixing ring 24 can better connect the machine head 1 and the front bearing housing 13 / the rear bearing housing 15 together.

[0049] Since the unilateral clearances between the main shaft 11 and the left-end alternate bearing 17 and the left-end magnetic bearing are only 0.1 mm and 0.2 mm respectively, when the eccentricity is too large, simply adjusting the inner hexagon bolt of the front bearing housing 13 cannot adjust the eccentricity to within the specified range, and at this time, it is necessary to adjust the rear bearing housing 15.

[0050] According to the obtained eccentricity values of the X-axis and Z-axis, loosen the lock nut provided at the right end of the rear bearing housing 15, and on the basis of adjusting the inner hexagon bolt of the front bearing housing 13, also set an inner hexagon bolt on the fixing hole 26 of the adjusting tooling frame 22 at the right end of the rear bearing housing 15. An annular cushion plate is also provided between this inner hexagon bolt and the cross-section 27 on the right-end adjusting tooling frame 22; screw the inner hexagon bolt into the second threaded hole of the rear bearing housing 15, and cooperate with the annular cushion plate and the cross-section 27 to displace the rear bearing housing 15.

[0051] At this time, lock the lock bolts on the left side of the front bearing housing 13 and the right side of the rear bearing housing 15, and re-establish the origin of the coordinate system of the machine head 1, the outer circle H, and the outer circle G. By comparing and evaluating the three, and determining that the concentricity of the machine head 1 is within the specified range and meets the requirements. When it is determined that the concentricity meets the requirements, the machine head 1 and the motor foot 4 can be removed from the eccentric tooling 2 at the same time.

[0052] For example: The eccentricity values of the front bearing housing 13 evaluated by the origin of the coordinate system of the machine head 1 are: X-axis +0.03 mm, Z-axis +0.05 mm

[0053] Loosen the bolts on the left side of the front bearing housing 13. Relative to the above eccentric data, screw the corresponding bolts into the threaded holes of the front bearing housing 13 to cause the front bearing housing 13 to move in the X+ axis direction; screw the corresponding bolts into the threaded holes of the front bearing housing 13 to cause the front bearing housing 13 to move in the Z+ axis direction.

[0054] The eccentric adjustment method is as follows:

[0055] S1. First, with the tooling table 21 as the center, a three-coordinate platform 3 is set below the tooling table 21, where the side of the tooling table 21 with the slide rail 23 is the top surface of the tooling table 21;

[0056] S2. A magnetic levitation machine head 1 is set above the top surface of the tooling table 21. The machine head 1 is provided with a main shaft 11, a front bearing housing 13, a rear bearing housing 15, and a motor 16; among them, the front bearing housing 13 is sleeved on the left end of the main shaft 11, the rear bearing housing 15 is sleeved on the right end of the main shaft 11, and the motor 16 is sleeved in the middle of the main shaft 11 and its left and right ends respectively abut against the front bearing housing 13 and the rear bearing housing 15;

[0057] S3. Place the tooling table 21 on the three-coordinate platform 3 with its top surface facing away from the three-coordinate platform 3;

[0058] S4. Set two groups of adjusting tooling frames 22. Slide a group of adjusting tooling frames 22, the motor foot 4, and a group of adjusting tooling frames 22 in sequence in the slide rail 23, and use bolts to fix the motor foot 4 on the tooling table 21; then slide the adjusting tooling frame 22 again so that the first threaded hole and the second threaded hole are fixed below the corresponding fixing holes 26;

[0059] S5. Use bolts to fix the two groups of adjusting tooling frames 22 and the machine head 1 in the current position to ensure that the first threaded hole and the second threaded hole correspond to the fixing holes 26;

[0060] S6. Set an internal hexagonal bolt and make it pass through the first threaded hole and the corresponding fixing hole 26 to fixedly connect the front bearing housing 13 and the left-end adjusting tooling frame 22 together, and set an annular cushion plate between the internal hexagonal bolt and the cross-section 27 on the left-end adjusting tooling frame 22;

[0061] S7. Set an internal hexagonal bolt again and make it pass through the second threaded hole and the corresponding fixing hole 26 to fixedly connect the rear bearing housing 15 and the right-end adjusting tooling frame 22 together, and also set an annular cushion plate between this internal hexagonal bolt and the cross-section 27 on the right-end adjusting tooling frame 22.
