[0001] The present invention relates to the technical field of rotary transformers, and in particular to an adjustment device and an adjustment method thereof that are suitable for multiple rotary transformers. Background Art

[0002] The inertial navigation precision test turntable is a key equipment for high-precision testing. Its installation precision ensures the accuracy and reliability of the test. Since different application scenarios have different requirements on the performance, precision, size, etc. of the rotary transformer, it is often necessary to design different types of rotary transformers to meet these specific needs. However, this brings inconvenience in using them in combination with the turntable. One type of rotary transformer requires a corresponding turntable. Only by using them together can high-precision angle control and measurement be achieved. Therefore, the existing adjustment device has great limitations. Therefore, the present invention provides an adjustment device and an adjustment method thereof that are suitable for a variety of rotary transformers. Summary of the invention

[0013] A regulating method using a regulating device adaptable to multiple rotary transformers includes the following steps.

[0014] Step 1: Measure the dimensions of the stator and rotor of the rotary transformer, and thus the matching dimensions of the rotor connecting shaft and the stator adapter, then process the required rotor connecting shaft and stator adapter, and then make the stator and rotor of the rotary transformer match and install with the rotor connecting shaft and the stator adapter respectively.

[0016] Step three: drive the fixed gear ring to rotate, under the action of the arc-shaped permanent magnetic strip plate 1 and the permanent magnetic short rod 2, the limit slide plate and the fixed square rod move synchronously in the direction close to the axis of the annular base frame, first make the fan-shaped friction strip plate contact the positioning ring plate, under the action of the fan-shaped friction strip plate, the position of the positioning ring plate is locked, the fixed square rod continues to move, the spring between the fixed square rod and the limit slide plate is compressed, and finally the end of the fixed square rod closest to the axis of the annular base frame engages with the groove on the stator adapter, thereby fixing the stator adapter.

[0017] Step 4: Drive the positioning ring frame to slide relative to the circular base so that the centering square rod on the positioning ring frame corresponds to the position of the groove on the stator adapter, and then drive the centering gear ring to rotate. Under the action of the arc-shaped permanent magnetic strip plate 2 and the permanent magnetic short rod 3, the centering square rod moves toward the direction close to the axis of the positioning ring frame, and finally the end of the centering square rod closest to the axis of the positioning ring frame engages with the groove on the rotor connecting shaft, thereby fixing the rotor connecting shaft.

[0018] Step 5: Drive the positioning ring frame to move downward, and the four limiting short rods on the positioning ring frame move downward synchronously.

At this time, the rotor connecting shaft can rotate relative to the stator adapter seat.

[0019] Compared with the prior art, the present invention has the following beneficial effects: (1) By utilizing the configuration of the rotor connecting shaft and the stator adapter, the present invention greatly reduces the problem that the turntable cannot be used rationally due to the wide variety of models of the rotary transformer. (2) The present invention can quickly realize the positioning and fixing of the rotor connecting shaft and the stator adapter through the mutual cooperation of the positioning component, the fixing component, and the centering component, without requiring the operator to have complex assembly experience, thereby lowering the technical threshold of the operator.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] Example: Reference Figure 1-Figure 12 A rotary transformer adjustment device adapted to various types of rotary transformers includes a circular base 101, on which a rotor connecting shaft 104 and a stator adapter 105 are movably arranged, and a positioning component, a fixing component, and a centering component are also arranged on the circular base 101. The positioning component includes an annular base frame 103, and the annular base frame 103 is fixedly mounted on the circular base 101. Six positioning slide plates 110 are slidably mounted in a circular array on the annular base frame 103. The ends of the positioning slide plates 110 closest to the axis of the annular base frame 103 are fixedly provided with positioning short Column 111, the lower surface of the stator adapter 105 is provided with 6 slots in a circular array that cooperate with the positioning short column 111, a positioning ring plate 107 is rotatably mounted on the annular base 103, and 6 arc-shaped permanent magnet blocks 109 are fixedly provided in a circular array on the positioning ring plate 107, and the end of the positioning slide plate 110 farthest from the axis of the annular base 103 is fixedly provided with a permanent magnet short rod 112, the arc-shaped permanent magnet block 109 is used to push the corresponding permanent magnet short rod 112 to move, and the arc-shaped permanent magnet block 109 and the permanent magnet short rod 112 are adsorbed on each other.

[0035] A positioning gear ring 115 is rotatably mounted on the annular base frame 103, and the positioning gear ring 115 is fixedly connected to the adjustment ring frame 106. A positioning motor 120 is fixedly mounted on the annular base frame 103, and a positioning gear 122 is fixedly mounted on the output shaft of the positioning motor 120. The positioning gear 122 and the positioning gear ring 115 are meshed to form a gear pair.

[0036] Start the positioning motor 120 to drive the positioning gear 122 to rotate, that is, the positioning gear ring 115 rotates, the positioning ring plate 107 rotates synchronously, and the arc-shaped permanent magnet block 109 on the positioning ring plate 107 rotates synchronously. Under the action of the arc-shaped permanent magnet block 109, the permanent magnet short rod 112 moves toward the direction close to the axis of the annular base frame 103. Since the arc-shaped permanent magnet block 109 and the permanent magnet short rod 112 are mutually adsorbed, during the process of the permanent magnet short rod 112 moving relative to the arc-shaped permanent magnet block 109, the permanent magnet short rod 112 is always in contact with the arc-shaped permanent magnet block 109, and the positioning slide plate 110 and the positioning short column 111 corresponding to the permanent magnet short rod 112 move synchronously to the direction close to the axis of the annular base frame 103. Move in the direction of the axis of the annular base 103, that is, the six positioning slides 110 move synchronously in the direction close to the axis of the annular base 103 or synchronously move in the direction away from the axis of the annular base 103, that is, the position of the positioning short column 111 is adjusted according to the position of the slot hole on the stator adapter 105 that cooperates with the positioning short column 111, and then the slot hole on the stator adapter 105 is engaged with the corresponding positioning short column 111. At this time, the lower surface of the stator adapter 105 and the upper surface of the positioning slide 110 are on the same plane. Under the action of the positioning short column 111, the stator adapter 105 cannot rotate relative to the positioning slide 110.

[0037] The fixed component includes an annular support plate 108, which is fixedly mounted on the annular base frame 103. Six fixed square rods 119 are movably arranged in a circular array on the annular support plate 108. Six grooves cooperating with the fixed square rods 119 are also arranged in a circular array on the stator adapter 105. The ends of the fixed square rods 119 closest to the axis of the annular base frame 103 are chamfered to form a smooth transition surface. Six limiting slide plates 113 are slidably mounted in a circular array on the annular support plate 108. The fixed square rods 119 are slidably mounted on the corresponding limiting slide plates 113. A spring is arranged between the limiting slide plates 113 and the corresponding fixed square rods 119. The ends of the limiting slide plates 113 closest to the axis of the annular base frame 103 are fixedly arranged with fan-shaped friction strips 114. When the fan-shaped friction strips 114 and the positioning ring plate 107 are in contact, there is friction between the two. The fan-shaped friction strips 114 are used to limit the position of the positioning ring plate 107.

[0038] A fixed gear ring 116 is also rotatably mounted on the annular base frame 103, and six arc-shaped permanent magnetic strips 117 are fixedly arranged in a circular array of the fixed gear ring 116. The ends of the fixed square rods 119 farthest from the axis of the annular base frame 103 are fixedly arranged with permanent magnetic short rods 118. The arc-shaped permanent magnetic strips 117 are used to push the corresponding permanent magnetic short rods 118 to move, and the arc-shaped permanent magnetic strips 117 and the permanent magnetic short rods 118 are attracted to each other. A fixed motor 121 is fixedly mounted on the circular base 101, and a fixed gear 123 is fixedly mounted on the output shaft of the fixed motor 121. The fixed gear 123 and the fixed gear ring 116 are meshed to form a gear pair.

[0039] In the initial position, the spring between the limiting slide 113 and the corresponding fixed square rod 119 is not compressed. At this time, the limiting slide 113 is located at the farthest position from the axis of the annular base frame 103, that is, the fan-shaped friction strip 114 is not in contact with the positioning ring plate 107.

[0040] After the stator adapter 105 is engaged with the positioning short column 111, the fixed motor 121 is started to drive the fixed gear 123 to rotate, so that the fixed gear ring 116 rotates, and the six arc-shaped permanent magnetic strips 117 on the fixed gear ring 116 rotate synchronously. Under the action of the arc-shaped permanent magnetic strip 117, the permanent magnetic short rod 2 118 corresponding to the arc-shaped permanent magnetic strip 117 moves toward the direction close to the axis of the annular base 103. Under the action of the spring between the limiting slide 113 and the fixed square rod 119, the limiting slide 113, the fan-shaped friction strip 114, and the fixed square rod 119 move synchronously toward the direction close to the axis of the annular base 103. Since the arc-shaped permanent magnetic strip 117 and the permanent magnetic short rod 2 118 are mutually adsorbed, during the process of the permanent magnetic short rod 2 118 moving relative to the arc-shaped permanent magnetic strip 117, the permanent magnetic short rod 2 118 is always in contact with the arc-shaped permanent magnetic strip 117.

[0041] During the movement of the fixed square rod 119, the fan-shaped friction strip 114 contacts the positioning ring plate 107. At this time, the curved surface of the fan-shaped friction strip 114 closest to the axis of the annular base frame 103 and the outer circumferential surface of the positioning ring plate 107 are on the same circumferential surface. The permanent magnetic short rod 118 continues to move. That is, at this time, the fixed square rod 119 moves relative to the limiting slide 113 in the direction close to the axis of the annular base frame 103. The spring between the limiting slide 113 and the fixed square rod 119 is compressed. At this time, under the action of the friction force between the positioning ring plate 107 and the fan-shaped friction strip 114, the positioning ring plate 107 is 7 cannot rotate freely, that is, the position of the positioning ring plate 107 is locked, and then the position of the positioning short column 111 is locked, and then the end of the fixed square rod 119 closest to the axis of the annular base 103 is engaged with the groove on the stator adapter 105. Under the action of the transition curved surface on the end of the fixed square rod 119 closest to the axis of the annular base 103, it is easy to achieve the engagement of the fixed square rod 119 with the groove on the stator adapter 105, and finally the fixed square rod 119 is completely engaged with the groove on the stator adapter 105, that is, the position of the stator adapter 105 is locked.

[0042] The centering assembly includes an annular base plate 124, and a positioning ring frame 106 is also slidably installed on the circular base 101. The annular base plate 124 is slidably installed on the positioning ring frame 106. A spring is arranged between the positioning ring frame 106 and the annular base plate 124. A positioning electric cylinder 102 is fixedly installed on the lower surface of the circular base 101. The piston rod end of the positioning electric cylinder 102 is fixedly connected to the positioning ring frame 106. An annular centering seat 125 is rotatably installed on the annular base plate 124. Four centering square rods 130 are slidably installed in a circular array on the annular centering seat 125. Four grooves matching the centering square rods 130 are arranged in a circular array on the rotor connecting shaft 104. The ends of the centering square rods 130 closest to the axis of the annular centering seat 125 are chamfered to form a smooth transition curved surface.

[0043] The positioning ring frame 106 is fixedly provided with four limiting short rods 132 in a circumferential array, and the annular centering seat 125 is provided with four through holes that cooperate with the limiting short rods 132. In the initial position, the spring between the positioning ring frame 106 and the annular base plate 124 is not compressed. At this time, the limiting short rods 132 and the through holes on the annular centering seat 125 are in an engaged state. Under the action of the limiting short rods 132, the annular centering seat 125 cannot rotate relative to the annular base plate 124.

[0044] A centering gear ring 126 is rotatably mounted on the annular centering seat 125, and a centering motor 128 is fixedly mounted on the annular centering seat 125. A centering gear 127 is fixedly mounted on the output shaft of the centering motor 128. The centering gear 127 and the centering gear ring 126 are meshed to form a gear pair. Four arc-shaped permanent magnetic strips 129 are fixedly arranged in a circular array on the centering gear ring 126. Permanent magnetic short rods 3 131 are fixedly arranged at the ends of the centering square rods 130 farthest from the axis of the annular centering seat 125. The arc-shaped permanent magnetic strips 129 are used to push the corresponding permanent magnetic short rods 131 to move, and the arc-shaped permanent magnetic strips 129 and the permanent magnetic short rods 131 are adsorbed on each other.

[0045] The axes of the annular base frame 103, the positioning ring plate 107, the annular support plate 108, the positioning gear ring 115, the fixing gear ring 116, the annular base plate 124, the annular centering seat 125, and the centering gear ring 126 are all on the same straight line.

[0046] After the fixed square rod 119 completes the fixation of the stator adapter 105, the positioning electric cylinder 102 is started to drive the positioning ring frame 106 to move relative to the circular base 101, and the annular bottom plate 124, the annular centering seat 125, and the centering square rod 130 are moved synchronously, that is, the centering square rod 130 is moved to the position corresponding to the groove on the rotor connecting shaft 104, and then the centering motor 128 is started to drive the centering gear 127 to rotate, and the centering gear ring 126 rotates. The four arc-shaped permanent magnetic strip plates 129 on the centering gear ring 126 rotate synchronously. Under the action of the arc-shaped permanent magnetic strip plates 129, the permanent magnetic short rod 131 moves toward the direction close to the axis of the annular centering seat 125, and the centering square rod 130 moves toward the direction close to the axis of the annular centering seat 125 synchronously. The permanent magnetic strip plate 2 129 and the permanent magnetic short rod 3 131 are attracted to each other, so in the process of the permanent magnetic short rod 3 131 moving relative to the arc-shaped permanent magnetic strip plate 2 129, the permanent magnetic short rod 3 131 is always in contact with the arc-shaped permanent magnetic strip plate 2 129, that is, the end of the centering square rod 130 closest to the axis of the annular centering seat 125 is engaged with the groove on the rotor connecting shaft 104, and under the action of the transition surface on the end of the centering square rod 130 closest to the axis of the annular bottom plate 124, it is easy to achieve the engagement of the centering square rod 130 with the groove on the rotor connecting shaft 104, and finally the centering square rod 130 is completely engaged with the groove on the rotor connecting shaft 104, that is, the position of the rotor connecting shaft 104 is locked, and the position of the axis of the rotor connecting shaft 104 is adjusted.

[0047] Then, the positioning electric cylinder 102 is started to drive the positioning ring frame 106 to move downward. At this time, the centering square rod 130 cannot move downward under the action of the rotor connecting shaft 104, that is, the annular bottom plate 124 and the annular centering seat 125 cannot move downward, and the positioning ring frame 106 moves downward relative to the annular bottom plate 124. The spring between the annular bottom plate 124 and the positioning ring frame 106 is compressed, and finally the limiting short rod 132 is disengaged from the stator adapter seat 105, that is, it contacts the restriction on the position of the annular centering seat 125. At this time, the annular centering seat 125 can rotate relative to the positioning ring frame 106, that is, at this time, the rotor connecting shaft 104 can rotate relative to the stator adapter seat 105, so that the stator adapter seat 105 can be tested conveniently.

[0048] Working principle: the circular base 101 is fixedly installed on the turntable base, the dimensions of the stator and rotor of the rotary transformer are measured, and thus the matching dimensions of the rotor connecting shaft 104 and the stator adapter 105, and then the required rotor connecting shaft 104 and stator adapter 105 are processed, and then the stator and rotor of the rotary transformer are respectively installed with the rotor connecting shaft 104 and the stator adapter 105, and then the positioning motor 120 is started, and the position of the positioning short column 111 is adjusted according to the position of the required slot on the stator adapter 105, and then the fixing motor 121 is started, first the fan-shaped friction strip 114 is used to lock the position of the positioning short column 111, and then the stator adapter 105 is engaged with the positioning short column 111, and then the positioning motor 120 is started again, and then the fixed square rod 119 is engaged with the groove on the stator adapter 105, that is, the position of the stator adapter 105 is locked.

[0049] Then start the positioning electric cylinder 102 to adjust the position of the centering square rod 130, and then start the centering motor 128 to make the centering square rod 130 engage with the groove on the rotor connecting shaft 104, that is, to lock the position of the rotor connecting shaft 104. Under the action of the fixed square rod 119 and the centering square rod 130, the axes of the rotor connecting shaft 104 and the stator adapter seat 105 are now in the same straight line. Then start the positioning electric cylinder 102 to make the limiting short rod 132 release the lock on the position of the annular centering seat 125, so as to facilitate the test of the rotation of the rotor connecting shaft 104, that is, to facilitate the test of the rotor of the rotary transformer.

[0050] A regulating method using a regulating device adaptable to multiple rotary transformers includes the following steps.

[0051] Step 1: Measure the dimensions of the stator and rotor of the rotary transformer, and thus the matching dimensions of the rotor connecting shaft 104 and the stator adapter 105, then process the required rotor connecting shaft 104 and stator adapter 105, and then make the stator and rotor of the rotary transformer match and install with the rotor connecting shaft 104 and the stator adapter 105 respectively.

[0052] Step 2: Drive the positioning ring plate 107 to rotate, and under the action of the arc-shaped permanent magnet block 109 and the permanent magnet short rod 112, the positioning slide plate 110 moves toward the direction close to the axis of the annular base frame 103, that is, the position adjustment of the positioning short column 111 is realized, and then the slot hole on the stator adapter 105 that cooperates with the positioning short column 111 is engaged with the corresponding positioning short column 111, so that the stator adapter 105 is placed on the positioning slide plate 110.

[0053] Step three: drive the fixed gear ring 116 to rotate, under the action of the arc-shaped permanent magnetic strip plate 117 and the permanent magnetic short rod 2 118, the limiting slide plate 113 and the fixed square rod 119 move synchronously in the direction close to the axis of the annular base frame 103, first making the fan-shaped friction strip plate 114 contact the positioning ring plate 107, under the action of the fan-shaped friction strip plate 114, the position of the positioning ring plate 107 is locked, the fixed square rod 119 continues to move, the spring between the fixed square rod 119 and the limiting slide plate 113 is compressed, and finally the end of the fixed square rod 119 closest to the axis of the annular base frame 103 is engaged with the groove on the stator adapter 105, that is, the stator adapter 105 is fixed.

[0054] Step 4: Drive the positioning ring frame 106 to slide relative to the circular base 101, so that the centering square rod 130 on the positioning ring frame 106 corresponds to the position of the groove on the stator adapter 105, and then drive the centering gear ring 126 to rotate. Under the action of the arc-shaped permanent magnetic strip plate 2 129 and the permanent magnetic short rod 3 131, the centering square rod 130 moves toward the direction close to the axis of the positioning ring frame 106, and finally the end of the centering square rod 130 closest to the axis of the positioning ring frame 106 engages with the groove on the rotor connecting shaft 104, thereby achieving the fixation of the rotor connecting shaft 104.

[0055] Step 5: Drive the positioning ring frame 106 to move downward, and the four limiting short rods 132 on the positioning ring frame 106 move downward synchronously. The limiting short rods 132 disengage from the annular centering seat 125, that is, the contact to limit the position of the annular centering seat 125 is achieved. At this time, the rotor connecting shaft 104 can rotate relative to the stator adapter seat 105.

[0056] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
