Description

Technical Field

[0001] The invention relates to the technical field of torque motor assembly, and in particular to a method and a device for non-destructive precision assembly of a strong magnetic torque motor of an antenna base. Background Art

[0002] The strong magnetic torque motor is an important part of the antenna base transmission system in electronic equipment. Figure 6 As shown, it is used to output power to realize the azimuth rotation movement of the antenna base. As electronic equipment has higher and higher requirements for the azimuth rotation response speed of the transmission device, torque motors using strong magnets made of materials such as neodymium iron boron are becoming more and more widely used to meet the needs of lightweight products and high torque drive. In addition, the stator and rotor assembly coaxiality requirements of the torque motor are high, which can reach φ0.08mm. Strong magnetic torque motors have high economic value, long production cycles, and strong disturbance to production plans. In the process of installing the strong magnetic torque motor into the antenna base, it is necessary to install its rotor and stator into the antenna base turntable and base one by one. Because its rotor and stator are strong magnetic components, manual assembly is prone to magnetic attraction, causing damage to the motor.

[0003] The existing method of adjusting the coaxial accuracy in azimuth by adding a long screw guide and a crowbar at a fixed hole between the torque motor stator and the base can prevent magnetic attraction during the assembly process. However, the assembly accuracy cannot be guaranteed due to the hole gap, and the crowbar operation will damage the workpiece surface. The torque motor assembly in the antenna base is carried out after the antenna base turntable, base, and azimuth bearing are assembled. However, due to the manufacturing errors of the above-mentioned antenna base system itself, such as the radial runout of the azimuth bearing and assembly errors, a tooling and assembly method for assembling a torque motor and an actuator combined with a torque motor described in publication number CN111181327B cannot adaptively adjust the coaxiality of the torque motor rotor and stator within the allowable accuracy range. Component interference may occur during the assembly process, thereby causing product damage.

[0004] Based on the retrieval of the above information, a non-destructive precision assembly method and device for a strong magnetic torque motor of an antenna base is proposed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a method and device for lossless precision assembly of a strong magnetic torque motor of an antenna base, which solves the problem that traditional means cannot be used for precise, lossless and efficient assembly of strong magnetic torque motors in existing antenna bases.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a non-destructive precision assembly method of a strong magnetic torque motor of an antenna base, specifically comprising the following steps: S1. After assembling the turntable, azimuth bearing and base of the electronic equipment antenna seat, place the base vertically upward and keep its levelness within 2mm / m; S2. Assemble the torque motor rotor into the turntable, and use screws to fix the torque motor rotor in the turntable with a hole position spaced apart circumferentially; S3, put the guide piece on the outer periphery of the top of the torque motor rotor, and use screws to pass through the guide piece and the remaining holes in S2 in sequence to fix the guide piece on the torque motor rotor; S4. After fixing the adjusting piece and the threaded sleeve, assemble the torque motor stator at the bottom of the adjusting piece, use a crane to hoist the adjusting piece to the top of the guide piece, so that the adjusting piece and the threaded sleeve are sleeved on the outer periphery of the guide piece, remove the crane, rotate the adjusting piece, so that the adjusting piece drives the threaded sleeve to rotate downward in the guide piece, until the lower end surface of the torque motor stator is 1 mm away from the top of the base; S5, judging whether there will be interference between the stator and the base of the torque motor, if not, go to S6, if yes, go to S10; S6, rotate the adjustment piece to make the adjustment piece drive the threaded sleeve to rotate, so that the torque motor stator is assembled into the base. After the torque motor stator falls into place, determine whether the torque motor stator is aligned with the mounting hole on the base. If yes, go to S8, if no, go to S7; S7, reversely rotate the adjustment member so that the adjustment member drives the stator of the torque motor to align with the mounting hole on the base; S8, separate the adjusting member from the threaded sleeve, control the crane to make the adjusting member drive the torque motor stator to descend vertically, and after the torque motor stator enters the base, use screws to pass through the mounting holes to fix the torque motor stator in the base; S9, remove the adjustment member from the guide member, loosen the screws, separate the guide member from the torque motor rotor, and use the screws to pass through the remaining holes on the torque motor rotor to finally fix the torque motor rotor to the turntable; S10, pre-adjust the three groups of azimuth clearance adjustment parts on the adjustment part, and then go to S5.

[0007] The present invention is further configured as follows: the method of determining whether the torque motor stator and the base will interfere with each other in S5 includes: Six points are evenly divided in the circumferential direction of the torque motor stator and the base assembly surface as detection points. A ruler and a feeler gauge are used to check whether the torque motor stator and the base are in contact at each detection point. If yes, it means interference occurs, and if no, it means no interference occurs.

[0008] The present invention also discloses a non-destructive precision assembly device for a strong magnetic torque motor of an antenna base, comprising a guide member, an adjustment member and a threaded sleeve, wherein the threaded sleeve is fixedly mounted on the top of the adjustment member by bolts, the threaded sleeve and the adjustment member are both sleeved on the outer periphery of the guide member, and the threaded sleeve is threadedly matched with the guide member.

[0020] As a preferred solution, in order to realize the convenient assembly of the torque motor stator 505, the adjustment member 2 includes a fixed plate 201, a correction sleeve 202 is fixedly installed on the top of the fixed plate 201, and a stator positioning stop 203 used in conjunction with the torque motor stator 505 is provided at the bottom of the fixed plate 201. The single-side gap between the assembly surface of the torque motor stator 505 and the stator positioning stop 203 is 0.015mm. The outer periphery of the top of the fixed plate 201 is evenly spaced and threaded with internal hexagonal screws 204, and the bottom of the outer periphery of the internal hexagonal screw 204 is A positioning nut 205 is threadedly installed, and four lifting rings 206 are evenly spaced and fixedly installed on the top of the fixed plate 201 to provide support for the lifting of the crane. The threaded sleeve 3 is fixedly installed on the top of the correcting sleeve 202 by bolts, and the correcting sleeve 202 and the fixed plate 201 are both sleeved and slidably installed on the outer periphery of the hollow center rod 102, wherein the single-side clearance between the correcting sleeve 202 and the hollow center rod 102 is C, that is, 0.02mm≤C≤0.10mm, and the inner surface of the threaded sleeve 3 cooperates with the outer peripheral thread of the T-shaped threaded rod 103.

[0021] In this embodiment, after pre-fixing the torque motor rotor 504, the guide member 1 is fixed to provide guiding conditions for the adjustment member 2 and the threaded sleeve 3. After the torque motor stator 505 is assembled on the adjustment member 2 through the hexagonal screw 204 and the positioning nut 205, the torque motor stator 505 can be conveniently assembled.

[0022] Embodiment 2. This embodiment is an improvement on the previous embodiment. It is a non-destructive precision assembly device for a strong magnetic torque motor of an antenna base. It also includes three groups of azimuth gap adjustment members 4 evenly spaced on the periphery of the correction sleeve 202. The azimuth gap adjustment member 4 includes an adjustment plate 401. An adjustment screw 402 is penetrated on one side of the adjustment plate 401. One end of the adjustment screw 402 penetrates the correction sleeve 202 and is threadedly connected to the correction sleeve 202. An energy storage spring 403 is sleeved on the periphery of the adjustment screw 402. When the energy storage spring 403 is cut off for detection of a 20mm spring length, the spring stiffness P is 10-20N / mm, and the two ends of the energy storage spring 403 are respectively in contact with the opposite sides of the adjustment plate 401 and the correction sleeve 202. The periphery of the correction sleeve 202 and the adjustment screw are located Several step guide pins 404 are penetrated and slidably installed on the upper and lower sides of 402, one end of the step guide pin 404 penetrates the adjustment plate 401 and extends to the inside of the adjustment plate 401, and the other end of the step guide pin 404 is embedded and rotatably installed with an adjusting ball 405, and the maximum feeding distance of the adjusting ball 405 is 2*C, that is, the coaxiality φD=φ2*C between the rotor positioning stop 104 and the stator positioning stop 203. It is further explained that a stroke hole compatible with the step guide pin 404 is opened on the correction sleeve 202, and one end of the stroke hole is an end necking structure, that is, the opening diameter of the stroke hole near the guide member 1 end is 0.7 times the front end opening diameter. This structural design can prevent the step guide pin 404 from falling from the end of the stroke hole when the guide member 1 is missing.

[0023] As a detailed explanation, an initial scale line corresponding to the adjustment plate 401 in the azimuth gap adjustment member 4 is also arranged on the top of the fixed disk 201, and initial marks are arranged on one side of the adjustment plate 401 and on the head of the adjustment screw 402. When one side of the adjustment plate 401 is aligned with the initial scale line, and the initial mark point of the adjustment plate 401 is aligned with the initial mark point of the adjustment screw 402, it represents that the azimuth gap adjustment member 4 is in an initial state at this time. In order to realize the precise assembly of the strong magnetic torque motor in the antenna seat of the electronic equipment, in the initial state, the coaxiality of the rotor positioning stop 104 and the stator positioning stop 203 can be guaranteed to be within φ0.01mm. It is further explained that the coaxiality of the rotor positioning stop 104 and the stator positioning stop 203 can meet φ0.03mm at most.

[0024] The advantage of the second embodiment over the first embodiment is that the coaxiality between the deviation-correcting sleeve 202 and the base 503 can be adjusted to ensure lossless and efficient assembly of the torque motor stator 505 .

[0025] Further explanation: the hardness of the guide member 1 and the adjusting ball 405 is HRC35~42 The method for using the above-mentioned antenna base strong magnetic torque motor non-destructive precision assembly device specifically includes the following steps: S1. After assembling the turntable 501, the azimuth bearing 502 and the base 503 of the electronic equipment antenna seat 5, place the base 503 vertically upward and keep its levelness within 2 mm / m; S2, assembling the torque motor rotor 504 into the turntable 501, and fixing the torque motor rotor 504 in the turntable 501 with screws in a manner of a hole position spaced apart in the circumferential direction. Specifically, when the torque motor rotor 504 is installed into the turntable 501, the screws in the circumferential direction are tightened in place at every interval, that is, a screw is tightened in the circumferential direction, and a screw is temporarily left in the adjacent position, and the circumferential tightening is completed in a cycle in sequence; S3, fit the rotor positioning stop 104 onto the outer periphery of the top of the torque motor rotor 504, and use screws to pass through the assembly hole 105 and the remaining holes in S2 in sequence to fix the positioning plate 101 on the torque motor rotor 504; S4. After fixing the threaded sleeve 3 on the deflection correction sleeve 202 with bolts, assemble the torque motor stator 505 in the stator positioning stop 203, tighten the positioning nut 205, and with the cooperation of the hexagonal screw 204, complete the fixation of the torque motor stator 505. After tying the bottom end of the crane connecting rope to the lifting ring 206, use the crane to hoist the fixed plate 201 above the guide member 1, and make the deflection correction sleeve 202 and the threaded sleeve 3 successively sleeved on the hollow center rod 102 and the outer periphery of the T-shaped threaded rod 103, remove the crane, rotate the fixed plate 201, so that the fixed plate 201 drives the threaded sleeve 3 to rotate downward around the T-shaped threaded rod 103 through the deflection correction sleeve 202, until the lower end surface of the torque motor stator 505 is 1 mm away from the top of the base 503; S5. Determine whether the torque motor stator 505 and the base 503 will interfere with each other: Six points are evenly divided in the circumferential direction of the assembly surface of the torque motor stator 505 and the base 503 as detection points, and a ruler and a feeler gauge are used to check whether the torque motor stator 505 and the base 503 are in contact at each detection point. If yes, it indicates that interference occurs, and the process goes to S10; if no, it indicates that no interference occurs, and the process goes to S6; S6, rotating the fixed disk 201, so that the fixed disk 201 drives the threaded sleeve 3 to rotate through the correction sleeve 202, so that the torque motor stator 505 is assembled into the base 503, and after the torque motor stator 505 falls into place, judging whether the torque motor stator 505 is aligned with the mounting hole position on the base 503, if yes, go to S8, if no, go to S7; S7, reversely rotate the fixed disk 201, so that the fixed disk 201 drives the torque motor stator 505 to align with the mounting hole on the base 503; S8, tie the bottom end of the driving connecting rope to the lifting ring 206, remove the bolts, separate the adjusting member 2 from the threaded sleeve 3, control the fixing plate 201 to drive the torque motor stator 505 to descend vertically, and after the torque motor stator 505 enters the base 503, remove the positioning nut 205, and after the torque motor stator 505 is lowered into place, use screws to pass through the installation holes of the torque motor stator 505 to fix the torque motor stator 505 in the base 503; S9, remove the adjustment member 2 from the guide member 1, loosen the screws, separate the guide member 1 from the torque motor rotor 504, and use screws to pass through the remaining holes on the torque motor rotor 504 to finally fix the torque motor rotor 504 to the turntable 501; S10. Pre-adjust the three groups of azimuth gap adjustment members 4 on the adjustment member 2. Specifically, when it is determined in S5 that interference will occur, record the azimuth gap adjustment member 4 in the same orientation as the interference point and mark it. Loosen the adjustment screws 402 in the other two groups of azimuth gap adjustment members 4 by 1 / 4 turn respectively, and then tighten the adjustment screws 402 in the marked azimuth gap adjustment members 4 by 1 / 4 turn, and then turn to S5 until there is no interference.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
