[0002] In traditional servo motor systems, the servo motor itself is equipped with an independent motor shaft. When installing the equipment, it is usually necessary to use a coupling to connect the servo motor shaft to the shaft of other mechanical structures. Although this connection method is widely used, it has certain limitations in actual operation. Due to vibration and torque changes during motor operation, coupled with the slight concentricity deviation that may exist between different shafts, the shaft often shakes during operation. The shaking of the shaft not only affects the stability of the connection between the coupling and the shaft, but also may cause the coupling to wear more over time, leading to premature failure of the connection components, thereby affecting the operating accuracy and reliability of the entire mechanical system, and increasing equipment maintenance costs and downtime.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in 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.
[0020] See also Figure 1-Figure 6 The present invention provides a technical solution: an assembly structure of a servo motor, comprising a motor housing 1, a mounting hole 11 is provided on the motor housing 1, and is used to facilitate the installation of the motor. A rotor 12 is provided in the motor housing 1, and the rotor 12 is driven by the motor to rotate. The structure also includes: a rotating shaft 2 inserted into the rotor 12, and the rotor 12 is used to drive the rotating shaft 2 to rotate. One end of the rotating shaft 2 is connected to a working shaft 21, which is used to directly drive the device without connecting a coupling, thereby driving the remaining devices to work and rotate. The rotating shaft 2 is provided with a accommodating The groove 22 is used to allow the connecting strip 44 to protrude from the rotating shaft 2. The protruding connecting strip 44 cooperates with the clamping mechanism 3 to clamp the rotating shaft 2 in the rotor 12 to ensure that the rotating shaft 2 will not fall off in the rotor 12. The connecting strip 44 is arranged in the accommodating groove 22. The connecting strip 44 is provided with a tooth block 441. The tooth block 441 is clamped and fixed by the clamping arm 34. A connecting chamber 121 for accommodating the clamping mechanism 3 is provided in the rotor 12. The connecting chamber 121 is used to accommodate the clamping mechanism 3. The clamping mechanism 3 is used to clamp the connecting strip 44 , thereby fixing the rotating shaft 2, the clamping mechanism 3 includes a pressing block 31 arranged in the connecting chamber 121, when the rotating shaft 2 is inserted into the rotor 12, the rotor 12 drives the rotating shaft 2 to rotate, when the rotor 12 rotates, the pressing block 31 is subjected to the centrifugal force and moves downward in the connecting chamber 121, a pressing connecting arm 32 is provided at the bottom of the pressing block 31, the pressing block 31 moving downward drives the pressing connecting arm 32 to squeeze the rotating connecting arm 33, the pressing connecting arm 32 is connected to the rotating connecting arm 33, and a connecting hole 33 is provided in the rotating connecting arm 33 1. The connecting hole 331 connects the rotating connecting arm 33 to the connecting chamber 121. The connecting hole 331 is sleeved on the connecting rod provided on the connecting chamber 121, so that the rotating connecting arm 33 can rotate. When the connecting arm 32 is pressed down to squeeze the rotating connecting arm 33, the rotating connecting arm 33 is affected by the connecting hole 331 to rotate, thereby pushing the clamping arm 34 upward, so that the clamping arm 34 moves upward. The clamping arm 34 is limited by the connecting chamber 121 and can only move upward due to the thrust of the rotating connecting arm 33. Figure 4 As shown, the rotating connecting arm 33 is connected to the clamping arm 34, and the clamping arm 34 fixes the connecting strip 44. The clamping arm 34 pushed upward can clamp the tooth block 441 on the connecting strip 44, thereby fixing the rotating shaft 2 to ensure that it will not come off.
[0021] The shaft 2 includes a shaft housing 24, which is used to fix the center rod 4, and the receiving groove 22 receives the center rod 4. The receiving groove 22 is provided in the shaft housing 24, and the receiving groove 22 is used to receive the connecting strip 44, so as to ensure that the connecting strip 44 can extend outward, thereby protruding outward of the shaft housing 24, so as to contact the clamping arm 34. The shaft housing 24 is provided with a center rod 4, and the center rod 4 is used to drive the connecting strip 44 to extend outward or retract inward, such as Figure 6 As shown in the content, a connecting seat 41 is provided on the central rod 4, a first connecting shaft 411 is connected in the connecting seat 41, one end of a pushing arm 42 is connected to the first connecting shaft 411, the pushing arm 42 can rotate on the first connecting shaft 411 on the connecting seat 41, so as to push the connecting bar 44 upwards, and the connecting bar 44 is limited by the accommodating groove 22, so that when pushed, the movement trajectory of the connecting bar 44 can only be ensured in the accommodating groove 22, and the other end of the pushing arm 42 is connected to the second connecting shaft 43, and the function of the second connecting shaft 43 is to allow the connecting bar 44 to adapt to the connection of the pushing arm 42, and the second connecting shaft 43 is used to adjust the connection angle between the connecting bar 44 and the pushing arm 42, and the second connecting shaft 43 is arranged on the connecting bar 44.
[0022] From this, it can be concluded that in the first embodiment, when the motor is started, the rotor 12 starts to drive the rotating shaft 2 to rotate. As the rotor 12 rotates at a high speed, the pressing block 31 located in the connecting chamber 121 will be subjected to the action of centrifugal force. Since the direction of the centrifugal force is away from the center of rotation, the pressing block 31 will move downward in the connecting chamber 121 along the vertical direction. When the pressing block 31 moves downward, the pressing connecting arm 32 connected thereto also moves downward, and exerts an extrusion effect on the rotating connecting arm 33. Since the rotating connecting arm 33 is connected to the connecting rod in the connecting chamber 121 through the connecting hole 331, when being extruded by the pressing connecting arm 32, the rotating connecting arm 33 will rotate around the connecting rod. During the rotation of the rotating connecting arm 33, one end thereof connected to the clamping arm 34 will be lifted upward, thereby pushing the clamping arm 34 to move upward. Because the clamping arm 34 is limited by the limiting structure in the connecting chamber 121 and can only move upward, when the clamping arm 34 moves upward, its end will be accurately clamped between the tooth blocks 441 on the connecting strip 44. Through this tight snap-fitting, the connecting strip 44 is firmly fixed, thereby firmly fixing the rotating shaft 2 inside the rotor 12, ensuring that the rotating shaft 2 will not fall off or shake during the operation of the motor.
[0023] The center rod 4 also has the function of adjusting the position of the connecting strip 44 in the whole structure. When the extension length or position of the connecting strip 44 needs to be adjusted, a certain external force is applied to the center rod 4 (for example, in some specific designs, the external force can be applied by connecting the center rod 4 through an external control mechanism), and the center rod 4 will move axially. As the center rod 4 moves, the connecting seat 41 installed thereon will also move synchronously. Since the connecting seat 41 is connected to the push arm 42 through the first connecting shaft 411, the movement of the connecting seat 41 will drive the push arm 42 to rotate around the first connecting shaft 411. During the rotation of the push arm 42, the other end of the push arm 42 is connected to the connecting strip 44 through the second connecting shaft 43, thereby pushing the connecting strip 44 to extend or contract in the receiving groove 22. In this way, the position of the connecting strip 44 can be flexibly adjusted according to actual work requirements, so that the rotating shaft 2 can be fixed in the rotor 12. Such a connection method of the entire rotating shaft 2 effectively eliminates the connection with the working machine through the coupling, thereby solving the problems caused by the coupling.
[0024] See also Figure 7-Figure 11 As shown, a connecting groove is provided on the center rod 4, and a bearing shaft 51 is provided in the connecting groove. The bearing shaft 51 can rotate in the connecting groove. A first splicing tooth 511 and a first adjusting tooth 512 are provided on the bearing shaft 51. The length of the first adjusting tooth 512 is longer than that of the first splicing tooth 511. The first splicing tooth 511 and the first adjusting tooth 512 are arranged in a circular array on one side of the bearing shaft 51. The rotating shaft 2 also includes a sealing plate 23 provided on the rotating shaft housing 24. The sealing plate 23 has a size matching that of the center rod 4 at the center of the circle to ensure that the center rod 4 can move on the sealing plate 23. The second splicing tooth 52 is used to cooperate with the first splicing tooth 511. The second adjusting tooth 53 is engaged with the first adjusting tooth 512, and the second adjusting tooth 53 is engaged with the second splicing tooth 52. The setting is staggered, the tooth peak of the second splice tooth 52, the side opposite to the sealing plate 23 and the load-bearing shaft 51 is provided with a second splice tooth 52 and a second adjusting tooth 53, the second splice tooth 52 and the second adjusting tooth 53 match the positions of the first splice tooth 511 and the first adjusting tooth 512, such a setting can also ensure that when the first splice tooth 511 and the second splice tooth 52 are engaged, the first adjusting tooth 512 is engaged with the middle part of the tooth surface of the second adjusting tooth 53 and will not reach the position of the tooth bottom of the second adjusting tooth 53. In addition, the height of the first splice tooth 511 is consistent with the height of the second splice tooth 52. The advantage of such a design is that when the first splice tooth 511 is plugged into the plug interface 521, the distance between the load-bearing shaft 51 and the sealing plate 23 can be reduced.
[0025] There are at least two second splicing teeth 52 , and the interval between them is a splicing port 521 . The width of the splicing port 521 is consistent with the width of the first splicing tooth 511 . The splicing port 521 allows the first splicing tooth 511 to be spliced, thereby shortening the distance between the load-bearing shaft 51 and the sealing plate 23 .
[0026] like Fig. 9 As shown, a moving groove 532 is provided on the sealing plate 23, and the moving groove 532 is used to allow the anti-compression spring 533 to ensure that the anti-compression spring 533 can move in the moving groove 532. The moving groove 532 is provided with an anti-compression spring 533, and the anti-compression spring 533 is used to allow the second adjusting tooth 53 to achieve a reset effect, and also gives the function of allowing the second adjusting tooth 53 to move. The top of the anti-compression spring 533 and the second adjusting tooth 53, the bottom of the second adjusting tooth 53 are provided with a baffle 531, and the baffle 531 is used to prevent the second adjusting tooth 53 from escaping from the moving groove In the case of 532, the baffle 531 is stuck in the movable groove 532. Such a design allows the second adjusting tooth 53 to move with the movement of the first adjusting tooth 512 when the first adjusting tooth 512 moves. When the first adjusting tooth 512 approaches, the second adjusting tooth 53 can move backward, so that the compression spring 533 is squeezed. To meet the above requirements, the height of the compression spring 533 plus the height of the second adjusting tooth 53 must be higher than the height of the second plug-in tooth 52. In addition, the compression spring 533 is arranged in a circular shape on the second adjusting tooth 53.
[0027] The sealing plate 23 is provided with a spring baffle 54 on the other side of the second plug-in tooth 52, and a return spring 55 is provided on the spring baffle 54. The spring baffle 54 not only bears the return spring 55, but also blocks the anti-compression spring 533. The material of the spring baffle 54 is selected to be pressure-resistant and wear-resistant. The center rod 4 is plugged into the sealing plate 23 and the return spring 55. A pressing button 56 is provided at the end point of the center rod 4. During installation, the rotating shaft 2 is plugged into the rotor 12, passes through the rotor 12, and is finally plugged into the brake mechanism 14 and the encoder 15. The brake mechanism 14 and the encoder 15 block the pressing button 56. When the rotating shaft 2 is squeezed hard, the pressing button 56 is subjected to a reaction force, which drives the center rod 4 inward to move. At this time, the return spring 55 is in a squeezed state, thereby driving the load-bearing shaft 51 and the sealing plate 23 to separate.
[0028] From this, we can derive a second embodiment. When the rotating shaft 2 is inserted into the rotor 12, passes through the rotor 12, and is finally inserted into the brake mechanism 14 and the encoder 15, a certain amount of cavities are provided in the brake mechanism 14 and the encoder 15 to cooperate with the installation of the rotating shaft 2. The brake mechanism 14 and the encoder 15 block the pressing button 56. When the rotating shaft 2 is squeezed, the pressing button 56 is subjected to a reaction force, driving the center rod 4 to move inward. At this time, the return spring 55 is squeezed, thereby driving the load-bearing shaft 51 and the sealing plate 23 to separate. At this time, the second adjusting tooth 53 loses the compressive force of the first adjusting tooth 512, and thus moves with the first adjusting tooth 512 according to the rebound force of the compression spring 533. At this time, the first plug-in tooth 511 is disengaged from the control of the plug-in interface 521, and the first adjusting tooth 512 will slide to the second adjusting tooth according to the tooth surface of the second adjusting tooth 53. At the tooth bottom of the segment tooth 53, the first adjusting tooth 512 drives the load-bearing shaft 51 to rotate slightly, and the rotation angle is the distance from the tooth surface of the second adjusting tooth 53 to the tooth bottom, and then the rotating shaft 2 is released. At this time, the center rod 4 is not subject to the thrust toward the inside of the motor during installation, and the reset spring 55 rebounds the press button 56 to drive the center rod 4 to reset and move. The displacement of the press button 56 rebounds is borne by the cavity. The reset center rod 4 drives the load-bearing shaft 51 to move toward the sealing plate 23. At this time, the first splicing tooth 511 is affected by the rotational displacement of the load-bearing shaft 51, and will be changed from the position where the plug-in interface 521 is plugged in to the second splicing tooth 52, thereby limiting the center rod 4 from returning to the previous position. Since the center rod 4 moves backward and is locked by the first splicing tooth 511 on the second splicing tooth 52, it drives the rotation of the push arm 42, and pushes the connecting strip 44 outward to be plugged and fixed.
[0029] When it is necessary to disassemble the center rod 4, it is only necessary to push the rotating shaft 2 into the motor again and repeat the installation steps. The load-bearing shaft 51 moves away from the closing plate 23, and the first connecting tooth 511 is disengaged from the control of the second connecting tooth 52. The second adjusting tooth 53 continues to move with the movement of the first adjusting tooth 512, so that the first adjusting tooth 512 drives the load-bearing shaft 51 to rotate, so that the first adjusting tooth 512 is affected by the second adjusting tooth 53 and slides to the bottom of the second adjusting tooth 53, so that the first connecting tooth 511 can be smoothly engaged in the plug-in interface 521, resetting the position of the load-bearing shaft 51 and the closing plate 23, thereby recovering the connecting strip 44 pushed outward, releasing the engagement with the engaging mechanism 3, and then pulling out the connecting strip 44.
[0030] The shaft housing 24 is provided with at least two receiving grooves 22, specifically eight, which are arranged in a circle array around the outer side of the shaft housing 24. Figure 3As shown, such a design can ensure the stability of the connection of the shaft 2 as much as possible during installation to prevent accidents caused by unstable connection on one side during operation. The number of corresponding connecting strips 44 is at least two, and a knurling is provided on the shaft housing 24, and a receiving groove 22 is provided in the knurling.
[0031] The motor housing 1 further includes a bearing 13 arranged on the rotating shaft 2 , a brake mechanism 14 arranged on the rotating shaft 2 , and an encoder 15 arranged on the rotating shaft 2 .
[0032] When the assembly structure of the servo motor is used, the rotating shaft 2 is first inserted into the rotor 12, and then passed through the rotor 12, and finally the brake mechanism 14 and the encoder 15 are inserted. The cavities in the brake mechanism 14 and the encoder 15 are adapted to the installation of the rotating shaft 2, and at the same time, the pressing button 56 is blocked. The rotating shaft 2 is pressed hard, and the pressing button 56 is driven by the reaction force to drive the center rod 4 to move inward, the reset spring 55 is squeezed, the bearing shaft 51 is separated from the sealing plate 23, and the second adjustment tooth 53 moves with the first adjustment tooth 512 under the action of the compression spring 533, and the first plug-in tooth 511 is separated from the plug-in interface 521. After the first adjustment tooth 512 drives the bearing shaft 51 to rotate slightly, the rotating shaft 2 is released, and the center rod 4 drives the bearing shaft 51 to move toward the sealing plate 23 under the rebound of the reset spring 55, and the first plug-in tooth 511 moves into the second plug-in tooth 52, locking the center rod 4, and then driving the push arm 42 to rotate, pushing the connecting bar 44 outward, and clamping and fixing it with the clamping mechanism 3. After the motor is started, the rotor 12 drives the rotating shaft 2 to rotate at a high speed, and the pressing block 31 in the connecting chamber 121 moves downward under the action of centrifugal force, driving the pressing connecting arm 32 to move downward synchronously and squeeze the rotating connecting arm 33. The rotating connecting arm 33 rotates around the connecting rod in the connecting hole 331, pushing the clamping arm 34 to move upward. The clamping arm 34 is limited by the connecting chamber 121 and can only move upward. The end of the clamping arm 34 is clamped between the tooth blocks 441 on the connecting strip 44 to fix the connecting strip 44, thereby firmly fixing the rotating shaft 2 inside the rotor 12. In addition, the center rod 4 can drive the connecting strip 44 to extend or contract in the receiving groove 22 through the connecting seat 41, the first connecting shaft 411, the pushing arm 42, and the second connecting shaft 43 to adjust the position. During disassembly, the shaft 2 is pushed into the motor again, the bearing shaft 51 moves away from the sealing plate 23, the first plug-in tooth 511 is disengaged from the control of the second plug-in tooth 52, and the second adjustment tooth 53 continues to move with the first adjustment tooth 512. The first adjustment tooth 512 drives the bearing shaft 51 to rotate, so that it slides to the bottom of the tooth under the influence of the second adjustment tooth 53, so that the first plug-in tooth 511 is smoothly inserted into the plug interface 521, the bearing shaft 51 and the sealing plate 23 return to their initial positions, the connection strip 44 pushed outward is recovered, and the connection with the clamping mechanism 3 is released, and then the connection strip 44 can be pulled out. The shaft housing 24 is provided with a plurality of accommodating grooves 22 (such as eight in a circular array) and matched with a corresponding number of connection strips 44 to ensure the stability of the connection. The bearing 13, brake mechanism 14, and encoder 15 in the motor housing 1 cooperate to ensure the operation of the servo motor.
[0033] 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.
