[0002] Magnetic levitation high-speed motors have the advantages of high energy density, small structural size, and high efficiency. They have been widely used in industrial fields such as micro gas turbines, high-speed centrifugal compressors, molecular pumps, high-speed machining centers, and flywheel energy storage. In order to enable the motor to operate efficiently and stably, a target material assembly is often installed on the rotor core shaft to improve the stiffness and dynamic balance of the rotor.

[0003] The target assembly includes a gap ring, a stator punching sheet, a baffle plate and a target limiting fixture. At present, when assembling the target assembly, the baffle plate, the stator punching sheet and the gap ring are generally placed directly into the target limiting fixture from top to bottom, and the gap ring is manually pressed to calibrate the baffle plate, the stator punching sheet and the gap ring horizontally. This assembly method is time-consuming and labor-intensive, and after the assembly is completed, the baffle plate, the stator punching sheet and the gap ring are prone to cross-location, and the parallelism between the baffle plate, the stator punching sheet and the gap ring is poor, resulting in a low overall mechanical strength of the target assembly. Summary of the invention

[0004] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide an assembling method of a target assembly with reusable tooling, which is used to improve the assembling efficiency of the target assembly and make the structure of the assembled target assembly more stable.

[0005] Based on the above purpose, the present invention adopts the following technical solution: A method for assembling a target material assembly with a reusable tooling is used for assembling the target material assembly with a tooling device; the target material assembly includes a gap ring, a stator punching sheet, a baffle and a target material limiting tooling; the tooling device includes a base, a limiting piece and a pressure cover; the assembling method includes the steps of: S1.

Setting the target material limiting tooling on the base so that the target material limiting tooling is fixedly connected to the base; S3, placing the baffle, stator punching sheet and gap ring from the top of the limiter in sequence, so that the gap ring, stator punching sheet and baffle are sequentially sleeved on the limiter from top to bottom, so that the lower end of the gap ring, the stator punching sheet and the baffle are arranged between the limiter and the target material limit fixture; S4, put the gland on the top of the written limiter, so that the bottom end of the gland abuts against the top surface of the gap ring; S5. Use hydraulic equipment to apply pressure to the top surface of the gland to perform horizontal calibration on the baffle, stator punching and gap ring; S6. Use bolts to fix the gap ring and the target limiting fixture; S7. Remove the pressure cover, disassemble the base and the target limiting tooling, and remove the base and the limiting parts.

[0006] Furthermore, a first mounting groove and a first fastener are provided in the middle of the base, and a first threaded hole is provided at the bottom of the limiter; step S1 specifically comprises: setting the limiter on the base so that the limiter and the base are clearance-matched; the first fastener passes through the first mounting groove and is threadedly connected to the first threaded hole so that the limiter is fixedly connected to the base.

[0007] Furthermore, a second mounting groove and a second fastener are provided at the left and right ends of the base, and a second threaded hole is provided at the left and right ends of the bottom of the target material limiting tooling; step S2 is specifically: the target material limiting tooling is set on the base so that the target material limiting tooling and the base are gap-matched; the second fastener passes through the second mounting groove and is threadedly connected to the second threaded hole so that the target material limiting tooling is fixedly connected to the base.

[0009] The present invention provides an assembly method of a target material assembly with a reusable tooling, wherein the baffle plate, stator punching sheet and gap ring are sleeved on a limiter to avoid the baffle plate, stator punching sheet and gap ring from being mixed and misaligned during the assembly process of the target material assembly. At the same time, by using hydraulic equipment to apply pressure to the pressure cover to perform horizontal calibration on the baffle plate, stator punching sheet and gap ring, the time and human resources required for assembling the target material assembly are saved, and the parallelism between the baffle plate, stator punching sheet and gap ring after the assembly is completed is improved, thereby improving the stability of the target material assembly structure.

DETAILED DESCRIPTION

[0011] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0012] This embodiment provides a method for assembling a target material assembly of a repeatedly reusable tool, which is used for installing the target material assembly by a tooling device.

[0013] like Figure 1 As shown, the target assembly includes a gap ring 11, a stator punching sheet 12 and a baffle 13 arranged in sequence from top to bottom, and also includes a target limiting tool 14 sleeved on the gap ring 11, the stator punching sheet 12 and the baffle 13. The tooling device includes a base 21 and a limiting member 22, the limiting member 22 is installed on the base 21, the gap ring 11, the stator punching sheet 12 and the baffle 13 are sequentially sleeved on the limiting member 22 from top to bottom, and the target limiting tool 14 is installed on the base 21. Through the above arrangement, the base 21 can be used to fix the target material limiting fixture 14, and the limiting member 22 can limit the movement of the gap ring 11, the stator punching sheet 12 and the baffle plate 13 along the radial direction of the limiting member 22, so as to prevent the gap ring 11, the stator punching sheet 12 and the baffle plate 13 from being mixed and misaligned in the target material limiting fixture 14; thus, after heating and installing the target material assembly, the target material limiting fixture 14 will not be unable to be removed due to the expansion and extrusion of the gap ring 11, the stator punching sheet 12 and the baffle plate 13, so that the target material limiting fixture 14 can be used repeatedly, saving costs. In order to more clearly illustrate the technical solution of the present invention, it is also defined as follows: Figure 1 Top, bottom, left and right sides shown.

[0014] Specifically, the bottom outer diameter of the gap ring 11, the outer diameter of the stator punching sheet 12 and the outer diameter of the baffle 13 are substantially equal, and the difference with the inner diameter of the target material limiting fixture 14 is greater than or equal to 0.4 mm. The inner diameter of the gap ring 11, the inner diameter of the stator punching sheet 12 and the inner diameter of the baffle 13 are substantially equal, and the difference with the outer diameter of the limiting member 22 is greater than or equal to 0.06 mm and less than or equal to 0.4 mm. Through the above arrangement, while ensuring that the gap ring 11, the stator punching sheet 12 and the baffle 13 can be sleeved on the limiting member 22, the limiting member 22 can limit the movement of the gap ring 11, the stator punching sheet 12 and the baffle 13 along the radial direction of the limiting member 22.

[0015] like Figure 2 As shown, when the base 21, the stopper 22 and the target material stopper tooling 14 are assembled, the base 21 and the stopper 22 are clearance-matched to facilitate the assembly between the base 21 and the stopper 22. A first mounting groove 211 and a first fastener 212 are provided in the middle of the base 21, and a first threaded hole 221 is provided at the bottom of the stopper 22. The front end of the first fastener 212 can pass through the first mounting groove 211 and be threadedly connected to the first threaded hole 221, and the rear end is clamped in the first mounting groove 211, so that the stopper 22 is fixedly connected to the base 21. Among them, the first fastener 212 can be set as a hexagon socket bolt to make the connection between the base 21 and the stopper 22 more convenient and reliable. Specifically, the screw portion of the first fastener 212 can pass through the first mounting groove 211 and be threadedly connected to the threaded hole opened at the bottom of the stopper 22, and the nut portion is clamped in the first mounting groove 211 to fix the stopper 22 to the base 21. It is understandable that the first fastener 212 can also be configured as a screw, a latch or other fasteners, as long as they can fix the limiting member 22 and the base 21 together.

[0016] The base 21 and the target material limiting fixture 14 are clearance-matched to facilitate the assembly between the base 21 and the target material limiting fixture 14. The left and right sides of the base 21 are provided with a second mounting groove 213 and a second fastener 214, and the left and right ends of the bottom of the target material limiting fixture 14 are provided with a second threaded hole 141. The front end of the second fastener 214 can pass through the second mounting groove 213 and be threadedly connected with the second threaded hole 141, and the rear end is clamped in the second mounting groove 213. Among them, the second fastener 214 can be set as a hexagon socket bolt to make the connection between the target material limiting fixture 14 and the second fastener 214 more convenient and reliable. The second fastener 214 can also be set as a screw, a latch or other fasteners. It can be understood that a plurality of second fasteners 214 can also be set around the base 21 to meet various assembly requirements.

[0017] like Figure 2As shown, the limiting member 22 is provided with a chamfer 222 around its top to guide the gap ring 11, the stator punching sheet 12, the baffle 13 and the pressure cover 23 to be sleeved on the limiting member 22, thereby improving the convenience of assembling the target assembly and the tooling device.

[0018] like Figure 1 As shown, the tooling device also includes a pressure cover 23, and the pressure cover 23 includes a cover surface 231 and a cover body 232. Among them, the cover surface 231 is basically arranged in the horizontal direction; the cover body 232 is arranged around the bottom surface of the cover surface 231. The cover body 232 is at least partially sleeved on the limiter 22, and the bottom surface of the cover body 232 abuts against the gap ring 11. The pressure cover 23 is used to cooperate with the hydraulic press to perform horizontal calibration on the gap ring 11, the stator punching sheet 12 and the baffle 13 to ensure that there is no gap between the surfaces when the gap ring 11, the stator punching sheet 12 and the baffle 13 abut, so as to ensure the overall strength of the target assembly. Specifically, the difference between the inner diameter of the cover body 232 and the outer diameter of the limit column is greater than or equal to 0.06mm and less than or equal to 0.4mm, so as to prevent the cover body 232 and the gap ring 11 from being unevenly stressed due to misalignment when the hydraulic press presses the pressure cover 23. Furthermore, the shortest distance h between the bottom surface of the cover surface 231 and the stopper 22 in the vertical direction is greater than a preset spacing threshold, so as to prevent the bottom surface of the cover surface 231 from contacting the stopper 22 when the top surface of the pressure cover 23 is subjected to force, so that the stopper 22 is subjected to force and damages the target assembly and the tooling device. The spacing threshold can be adjusted according to actual needs.

[0019] like Figure 3 As shown, a first connection part 142 is provided around the top of the target limiting tooling 14, and a second connection part 111 is provided around the lower side of the outer wall of the gap ring 11. The left and right ends of the first connection part 142 and the second connection part 111 can be connected by a third fastener 15. Among them, the third fastener 15 can be set as a bolt, including a nut 151, a gasket 152, and an integrally formed screw 153 and a nut 154. Specifically, a first through hole 1421 is provided on the first connection part 142, and a second through hole 1111 is provided on the second connection part 111; the screw 153 part of the third fastener 15 can pass through the second through hole 1111 and the first through hole 1421, and be threadedly connected with the nut 151 to fix the first connection part 142 with the second connection part 111. More specifically, a gasket 152 is provided between the nut 151 and the first connecting portion 142 to increase the contact area between the nut 151 and the first connecting portion 142, and to improve the fixing strength of the third fastener 15 to the first connecting portion 142 and the second connecting portion 111. Furthermore, the inner diameter of the first through hole 1421 is larger than the inner diameter of the second through hole 1111 to prevent the screw 153 of the third fastener 15 from partially contacting the target material limiting fixture 14, making it inconvenient to remove the target material limiting fixture 14. When the target assembly is sleeved onto the rotor core shaft, the nut 151 of the third fastener 15 can be removed, and the target material limiting fixture 14 can be taken out and reused, saving costs.

[0020] A step surface 143 is provided around the bottom of the inner wall of the target limiting fixture 14, and the step surface 143 is used to support the baffle 13. The target limiting fixture 14 is provided with a corner clearance notch 144 around the top surface of the step surface 143, and the corner clearance notch 144 is used to avoid the baffle 13.

[0021] like Figure 4 As shown, the assembly method provided in this embodiment specifically includes the steps of: S1. Arrange the base 21 in a horizontal direction, and arrange the limiting member 22 on the base 21 so that the limiting member 22 is fixedly connected to the base 21; S2, setting the target material limiting tool 14 on the base 21, so that the target material limiting tool 14 is fixedly connected to the base 21; S3, put the baffle 13, the stator punching sheet 12 and the gap ring 11 in sequence from the top of the limiter 22, so that the gap ring 11, the stator punching sheet 12 and the baffle 13 are sequentially sleeved on the limiter 22 from top to bottom, so that the lower end of the gap ring 11, the stator punching sheet 12 and the baffle 13 are arranged between the limiter 22 and the target material limit fixture 14; S4, the pressure cover 23 is placed on the top of the limiter 22, so that the bottom end of the pressure cover 23 abuts against the top surface of the gap ring 11; S5. Use hydraulic equipment to apply pressure to the top surface of the gland 23 to perform horizontal calibration on the baffle 13, the stator punching sheet 12 and the gap ring 11; S6. Use bolts to fix the lower end of the gap ring 11 to the top of the target limiting fixture 14; S7, remove the pressure cover 23; disassemble the base 21 and the target limiting tool 14, and remove the base 21 and the limiting member 22.

[0022] The assembled target components are as follows: Figure 5 As shown. Through the above assembly method, the limiter 22 can limit the displacement of the baffle 13, the stator punching sheet 12 and the gap ring 11 along the radial direction of the limiter 22, and prevent the baffle 13, the stator punching sheet 12 and the gap ring 11 from being mixed and disordered in the target material limiting tooling 14. At the same time, by applying pressure to the pressure cover 23 through hydraulic equipment to horizontally calibrate the baffle 13, the stator punching sheet 12 and the gap ring 11, the time and human resources required for assembling the target assembly can be saved, and the parallelism between the baffle 13, the stator punching sheet 12 and the gap ring 11 after the assembly is completed is improved, thereby improving the stability of the target assembly structure. like Figure 2 and Figure 4As shown, step S1 specifically includes: setting the limiter 22 on the base 21 along the vertical direction, so that the limiter 22 and the base 21 are in clearance fit; the first fastener 212 passes through the first mounting groove 211 and is threadedly connected with the first threaded hole 221, so that the limiter 22 is fixedly connected to the base 21. In this way, the assembly between the limiter 22 and the base 21 is more convenient and stable.

[0023] like Figure 2 and Figure 4 As shown, step S2 specifically includes: setting the target material limiting fixture 14 on the base 21 along the vertical direction, so that the target material limiting fixture 14 and the base 21 are clearance-matched; the second fastener 214 passes through the second mounting groove 213 and is threadedly connected with the second threaded hole 141, so that the target material limiting fixture 14 is fixedly connected to the base 21. In the above manner, the assembly between the target material limiting fixture 14 and the base 21 is more convenient, and when the base 21 and the limiting member 22 need to be removed later, it is only necessary to disassemble the target material limiting fixture 14 and the base 21, which saves the time of disassembling the target assembly and the fixture device.

[0024] like Figure 3 and Figure 4 As shown, step S6 is specifically as follows: the screw rod 153 is passed through the second through hole 1111 and the first through hole 1421 from top to bottom until the nut 154 abuts against the top surface of the second connecting portion 111, the gasket 152 is sleeved on the lower end of the screw rod 153, and is locked with the nut 151, so that the gap ring 11 is fixedly connected to the target material limiting fixture 14. Through the above arrangement, the connection between the target material limiting fixture 14 and the gap ring 11 is more convenient. At the same time, after the target assembly is installed on the rotor core shaft of the motor, the target material limiting fixture 14 can be more conveniently removed, which is convenient for repeated use of the target material limiting fixture 14.

[0025] In summary, the present application provides a method for assembling a target assembly with a reusable tooling, wherein the limiting member 22 and the target limiting tooling 14 are first fixed, and then the baffle 13, the stator punching sheet 12 and the gap ring 11 are sleeved on the limiting member 22, so as to avoid the baffle 13, the stator punching sheet 12 and the gap ring 11 from moving in the radial direction of the limiting member 22 and causing mixed dislocation. By arranging a pressure cover 23 on the gap ring 11 and applying pressure to the pressure cover 23 using hydraulic equipment, the baffle 13, the stator punching sheet 12 and the gap ring 11 are horizontally calibrated, which saves the time and human resources required for pressing the baffle 13, the stator punching sheet 12 and the gap ring 11, improves the parallelism between the baffle 13, the stator punching sheet 12 and the gap ring 11 after the assembly is completed, and thus improves the mechanical strength of the target assembly. In addition, by sequentially assembling the limiter 22, the target limiter tooling 14, the baffle 13, the stator punching sheet 12, the gap ring 11 and the pressure cover 23, problems such as jamming and collision between the target assembly and the tooling device can be avoided, thereby improving the assembly efficiency of the target assembly.
