Description

Technical Field

[0001] This invention relates to the field of torque motor assembly technology, specifically to a non-destructive precision assembly method and apparatus for an antenna mount strong magnetic torque motor. Background Technology

[0002] A high-magnetic torque motor is an important component of the antenna mount drive system in electronic equipment. Its structure is shown in the attached figure. Figure 6 As shown, this is used to output power to achieve the azimuth rotation of the antenna mount. With increasingly stringent requirements for the azimuth rotation response speed of electronic equipment transmission devices, torque motors using powerful magnets made of materials such as neodymium iron boron are becoming more widely used to meet the demands of lightweight products and high-torque drive. Furthermore, the stator and rotor of torque motors require high coaxiality, down to φ0.08mm. High-magnetic torque motors have high economic value but long production cycles, significantly impacting production schedules. The process of installing a high-magnetic torque motor into the antenna mount requires sequentially installing its rotor and stator into the antenna mount turntable and base. Because the rotor and stator are strong magnetic components, manual assembly can easily lead to magnetic attraction, causing motor damage.

[0003] Existing methods involve using a long screw guide and a pry bar to adjust the coaxiality of the torque motor stator and base through fixed holes. This method can prevent magnetic attraction during assembly. However, the hole gaps cannot guarantee assembly accuracy, and prying can damage the workpiece surface. The torque motor assembly in the antenna mount is carried out after the antenna mount turntable, base, and azimuth bearing are assembled. However, due to manufacturing errors in the antenna mount system itself, such as radial runout of the azimuth bearing, and assembly errors, as described in the tooling and assembly method for assembling a torque motor and actuator as disclosed in CN111181327B, it is impossible to adaptively adjust the coaxiality of the torque motor rotor and stator within the allowable accuracy range. Component interference may occur during assembly, leading to product damage.

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

[0005] To address the shortcomings of existing technologies, this invention provides a non-destructive precision assembly method and apparatus for antenna mounts with strong magnetic torque motors, solving the problem that traditional methods cannot achieve precise, non-destructive, and efficient assembly when assembling strong magnetic torque motors in existing antenna mounts.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a non-destructive precision assembly method for an antenna mount strong magnetic torque motor, specifically comprising the following steps:

[0007] S1. After assembling the turntable, azimuth bearing and base of the electronic equipment antenna mount, place the base vertically upward and keep its levelness within 2mm / m.

[0008] S2. Assemble the torque motor rotor into the turntable and use screws to fix the torque motor rotor in the turntable with a circumferential spacing of one hole.

[0009] S3. Fit the guide piece onto the top outer periphery 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 onto the torque motor rotor;

[0010] S4. After fixing the adjusting part and the threaded sleeve, assemble the torque motor stator at the bottom of the adjusting part. Use a crane to hoist the adjusting part above the guide part, so that the adjusting part and the threaded sleeve are fitted around the outer periphery of the guide part. Remove the crane and rotate the adjusting part so that the adjusting part drives the threaded sleeve to rotate downward in the guide part until the lower end face of the torque motor stator is 1mm away from the top of the base.

[0011] S5. Determine whether there will be interference between the stator and the base of the torque motor. If no, proceed to S6. If yes, proceed to S10.

[0012] S6. Rotate the adjusting component to make the threaded sleeve 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, turn to S8; otherwise, turn to S7.

[0013] S7. Rotate the adjusting component in the opposite direction to align the stator of the torque motor with the mounting holes on the base.

[0014] S8. Separate the adjusting part from the threaded sleeve, control the crane to make the adjusting part drive the torque motor stator to descend vertically. 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.

[0015] S9. Remove the adjusting part from the guide part, then loosen the screws to separate the guide part from the torque motor rotor, and use screws to pass through the remaining holes on the torque motor rotor to finally fix the torque motor rotor to the turntable.

[0016] S10. Pre-adjust the three sets of azimuth clearance adjustment parts on the adjustment part, and then switch to S5.

[0017] The present invention is further configured such that: the method for determining whether the torque motor stator and the base will interfere in step S5 includes:

[0018] Six points are marked on the circumference of the mating surface between the stator and the base of the torque motor as test points. A ruler and feeler gauge are used to check whether the stator and the base of the torque motor come into contact at each test point. If they do, it means that interference occurs; if they do not, it means that no interference occurs.

[0019] The present invention also discloses a non-destructive precision assembly device for an antenna mount strong magnetic torque motor, comprising a guide, an adjusting component, and a threaded sleeve. The threaded sleeve is fixedly installed on the top of the adjusting component by bolts. Both the threaded sleeve and the adjusting component are sleeved on the outer periphery of the guide, and the threaded sleeve is threadedly engaged with the guide.

[0020] The present invention is further configured such that: the guide includes a positioning disk, a hollow center rod is fixedly installed in the middle of the top of the positioning disk, and a T-shaped threaded rod is integrally formed at the top of the hollow center rod.

[0022] The present invention is further configured such that: the adjusting component includes a fixed plate, a correction sleeve is fixedly installed on the top of the fixed plate, a stator positioning stop for use with the stator of the torque motor is opened on the bottom of the fixed plate, and four lifting rings are fixedly installed at even intervals on the top of the fixed plate;

[0023] The threaded sleeve is fixedly installed on the top of the correction sleeve by bolts. The correction sleeve and the fixing plate are both sleeved and slidably installed on the outer periphery of the hollow center rod. The inner surface of the threaded sleeve is threadedly engaged with the outer periphery of the T-shaped threaded rod.

[0024] The present invention is further configured such that: an internal hexagonal screw is threaded through and uniformly spaced on the outer periphery of the top of the fixed disk, and a positioning nut is threaded on the bottom of the outer periphery of the internal hexagonal screw.

[0025] The invention is further configured such that: three sets of azimuth gap adjusting components are evenly spaced on the outer periphery of the correction sleeve; each azimuth gap adjusting component includes an adjusting plate; an adjusting screw is inserted through one side of the adjusting plate; one end of the adjusting screw passes through the correction sleeve and is threadedly connected to the correction sleeve; an energy storage spring is sleeved on the outer periphery of the adjusting screw, and both ends of the energy storage spring are in contact with the opposite sides of the adjusting plate and the correction sleeve, respectively; several stepped guide pins are inserted through and slidably installed on the outer periphery of the correction sleeve and on both the upper and lower sides of the adjusting screw; one end of each stepped guide pin passes through the adjusting plate and extends into the interior of the adjusting plate; and an adjusting ball is embedded and rotatably installed on the other end of the stepped guide pin.

[0026] This invention provides a non-destructive precision assembly method and apparatus for antenna mount high magnetic torque motors. It has the following beneficial effects:

[0027] This invention assembles the torque motor rotor using spaced holes, then assembles guide components in the remaining holes to provide stable guiding and positioning space for the adjusting components and threaded sleeves. The torque motor stator is then assembled onto the adjusting components. The cooperation between the threaded sleeves and guide components facilitates the alignment of the torque motor stator with the mounting holes on the base. Furthermore, the cooperation between the azimuth gap adjusting components and guide components enables the correction and adjustment of the torque motor stator, effectively preventing interference between the torque motor stator and the base during assembly, thus achieving precise, non-destructive, and efficient assembly of the torque motor stator.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0041] Please see Figure 1-6 The present invention provides the following technical solutions:

[0042] Example 1: A non-destructive precision assembly device for a strong magnetic torque motor in an antenna mount, comprising a guide 1, an adjusting component 2, and a threaded sleeve 3, used for assembling the torque motor rotor 504 and the torque motor stator 505 in an electronic equipment antenna mount 5, as shown in the attached figure. Figure 6 As shown, the electronic equipment antenna mount 5 consists of a turntable 501, an azimuth bearing 502, a base 503, a torque motor rotor 504, and a torque motor stator 505.

[0043] As a preferred embodiment, in order to facilitate the installation of the guide component 1 and provide guiding support conditions for the installation of the adjusting component 2 and the threaded sleeve 3, the guide component 1 includes a positioning plate 101. The bottom of the positioning plate 101 is provided with a rotor positioning stop 104 that cooperates with the torque motor rotor 504. The single-sided gap between the assembly surfaces of the torque motor rotor 504 and the rotor positioning stop 104 is 0.015mm. The top of the positioning plate 101 is provided with several assembly holes 105. A hollow center rod 102 is fixedly installed in the middle of the top of the positioning plate 101. A T-shaped threaded rod 103 is integrally formed at the top of the hollow center rod 102.

[0044] As a preferred embodiment, to facilitate the assembly of the torque motor stator 505, the adjusting component 2 includes a fixed plate 201. A correction sleeve 202 is fixedly installed on the top of the fixed plate 201. A stator positioning stop 203, which mates with the torque motor stator 505, is provided on the bottom of the fixed plate 201. The mating surfaces of the torque motor stator 505 and the stator positioning stop 203 have a single-sided gap of 0.015mm. Internal hexagonal screws 204 are threaded through and evenly spaced along the outer periphery of the top of the fixed plate 201. The bottom of the outer periphery of the internal hexagonal screws 204... The threaded sleeve is fitted with a positioning nut 205. Four lifting rings 206 are also evenly fixedly installed on the top of the fixed plate 201 to provide support for the crane's lifting. The threaded sleeve 3 is fixedly installed on the top of the correction sleeve 202 by bolts. The correction sleeve 202 and the fixed plate 201 are both fitted and slidably installed on the outer periphery of the hollow center rod 102. The single-sided gap between the correction sleeve 202 and the hollow center rod 102 is C, that is, 0.02mm≤C≤0.10mm. The inner surface of the threaded sleeve 3 is threaded with the outer periphery of the T-shaped threaded rod 103.

[0045] In this embodiment, after the torque motor rotor 504 is pre-fixed, the guide member 1 is fixed to provide guiding conditions for the adjusting member 2 and the threaded sleeve 3. After the torque motor stator 505 is assembled onto the adjusting member 2 by the internal hexagon screw 204 and the positioning nut 205, the torque motor stator 505 can be conveniently assembled.

[0046] Example 2: This example is an improvement on the previous example. A non-destructive precision assembly device for an antenna mount strong magnetic torque motor further includes three sets of azimuth gap adjusting components 4 evenly spaced around the outer periphery of the correction sleeve 202. Each azimuth gap adjusting component 4 includes an adjusting plate 401. An adjusting screw 402 is inserted through one side of the adjusting plate 401. One end of the adjusting screw 402 passes through the correction sleeve 202 and is threadedly connected to it. An energy storage spring 403 is sleeved around the outer periphery of the adjusting screw 402. When a 20mm spring length is measured, the spring stiffness P = 10-20 N / mm. Both ends of the energy storage spring 403 are in contact with the opposite sides of the adjusting plate 401 and the correction sleeve 202, respectively. The outer periphery of the correction sleeve 202 is located on the adjusting screw. Several stepped guide pins 404 are slidably installed on both the upper and lower sides of 402. One end of the stepped guide pin 404 passes through the adjusting plate 401 and extends into the interior of the adjusting plate 401. The other end of the stepped guide pin 404 is fitted with and rotatably mounted with an adjusting ball 405. The maximum feed distance of the adjusting ball 405 is 2*C, that is, the coaxiality φD of the rotor positioning stop 104 and the stator positioning stop 203 is φ2*C. To further explain, a stroke hole adapted to the stepped guide pin 404 is opened on the correction sleeve 202, and one end of the stroke hole has an end necking structure, that is, the opening diameter of the stroke hole near the guide member 1 is 0.7 times the opening diameter of the front end. This structural design can prevent the stepped guide pin 404 from falling off the end of the stroke hole when the guide member 1 is missing.

[0047] As a detailed explanation, an initial scale line corresponding to the adjusting plate 401 in the azimuth gap adjusting component 4 is also provided on the top of the fixed plate 201. Initial marks are also provided on one side of the adjusting plate 401 and the head of the adjusting screw 402. When one side of the adjusting plate 401 is aligned with the initial scale line, and the initial marks of the adjusting plate 401 and the initial marks of the adjusting screw 402 are aligned, it means that the azimuth gap adjusting component 4 is in the initial state. In order to achieve the precision assembly of the strong magnetic torque motor in the antenna mount of 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. To further explain, the coaxiality of the rotor positioning stop 104 and the stator positioning stop 203 can meet a maximum of φ0.03mm.

[0048] The advantage of Embodiment 2 over Embodiment 1 is that the coaxiality of the correction sleeve 202 and the base 503 can also be adjusted to ensure the non-destructive and efficient assembly of the torque motor stator 505.

[0049] To further clarify, the hardness of guide component 1 and adjusting ball 405 is HRC35~42.

[0050] The method of using the above-mentioned antenna mount strong magnetic torque motor non-destructive precision assembly device specifically includes the following steps:

[0051] S1. After assembling the turntable 501, azimuth bearing 502 and base 503 of the electronic equipment antenna mount 5, place the base 503 vertically upward and keep its levelness within 2mm / m.

[0052] S2. Assemble the torque motor rotor 504 into the turntable 501. Use screws to fix the torque motor rotor 504 into the turntable 501 with a circumferential spacing of one hole. Specifically, when installing the torque motor rotor 504 into the turntable 501, tighten the circumferential screws at a circumferential spacing of one hole. That is, tighten one screw in the circumferential direction and leave one screw uninstalled in the adjacent position. Repeat this process until the circumferential tightening is complete.

[0053] S3. Fit the rotor positioning stop 104 onto the top outer periphery 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 onto the torque motor rotor 504.

[0054] S4. After fixing the threaded sleeve 3 to the correction sleeve 202 with bolts, assemble the torque motor stator 505 into the stator positioning stop 203, tighten the positioning nut 205, and complete the fixing of the torque motor stator 505 with the cooperation of the internal hexagon screw 204. After tying the bottom end of the crane connecting rope to the lifting ring 206, use the crane to lift the fixing plate 201 above the guide 1, and make the correction sleeve 202 and the threaded sleeve 3 successively fit around the hollow center rod 102 and the T-shaped threaded rod 103. Remove the crane, rotate the fixing plate 201, so that the fixing plate 201 drives the threaded sleeve 3 to rotate downward around the T-shaped threaded rod 103 through the correction sleeve 202 until the lower end face of the torque motor stator 505 is 1mm away from the top of the base 503.

[0055] S5. Determine whether there will be interference between the torque motor stator 505 and the base 503:

[0056] Six points are evenly divided in the circumferential direction of the assembly surface of the torque motor stator 505 and the base 503 as test points. Use a ruler and feeler gauge to check whether the torque motor stator 505 and the base 503 will contact each other at each test point. If yes, it means that interference occurs, and turn to S10. If no, it means that no interference occurs, and turn to S6.

[0057] S6. Rotate the fixed plate 201 so that the fixed plate 201 drives the threaded sleeve 3 to rotate through the straightening sleeve 202, so that the torque motor stator 505 is assembled into the base 503. After the torque motor stator 505 falls into place, determine whether the torque motor stator 505 and the mounting hole on the base 503 are aligned. If yes, go to S8; if no, go to S7.

[0058] S7. Rotate the fixed plate 201 in the opposite direction so that the fixed plate 201 drives the stator 505 of the torque motor to align with the mounting holes on the base 503.

[0059] S8. Tie the bottom end of the crane connecting rope to the lifting ring 206, remove the bolt, separate the adjusting part 2 from the threaded sleeve 3, control the fixed plate 201 to drive the torque motor stator 505 to descend vertically, after the torque motor stator 505 enters the base 503, remove the positioning nut 205, after the torque motor stator 505 has descended to the position, use screws to pass through the mounting holes of the torque motor stator 505 to fix the torque motor stator 505 in the base 503;

[0060] S9. Remove the adjusting part 2 from the guide part 1, then loosen the screws to separate the guide part 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 and the turntable 501.

[0061] S10. Pre-adjust the three sets of azimuth clearance adjustment parts 4 on the adjustment part 2. Specifically, when it is determined in S5 that interference will occur, record the azimuth clearance adjustment parts 4 in the same azimuth as the interference point and mark them. Loosen the adjustment screws 402 in the other two sets of azimuth clearance adjustment parts 4 by 1 / 4 turn each. Then tighten the adjustment screws 402 in the marked azimuth clearance adjustment parts 4 by 1 / 4 turn. Then turn to S5 until there is no interference.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
