Description

Technical Field

[0001] The present invention relates to the technical field of servo motors, and particularly to an assembly structure of a servo motor. Background Art

[0002] In a traditional servo motor system, the servo motor is equipped with an independent motor shaft. When installing the equipment, it is usually necessary to connect the shaft of the servo motor to the shaft of other mechanical structures by means of a coupling. Although this connection method is widely used, it has certain limitations in the actual operation process. Since the motor will generate vibration and torque changes during operation, and there may be slight concentricity deviations between different shafts, the shaft often shakes during operation. The shaking of the shaft will not only affect the stability of the connection part between the coupling and the shaft, but also, in the long term, may cause the coupling to wear more severely, resulting in premature failure of the connection components, thereby affecting the operation accuracy and reliability of the entire mechanical system, and increasing the equipment maintenance cost and downtime.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1-6 , the present invention provides a technical solution: an assembly structure of a servo motor, including a motor housing 1, on which an installation hole 11 is provided for facilitating 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. It further 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 with a working shaft 21, which is used to directly drive the device without the need to connect a coupling, so as to drive the rest of the device to work and rotate. A receiving groove 22 is provided on the rotating shaft 2, and the receiving groove 22 is used to allow the connecting strip 44 to protrude on 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, ensuring that the rotating shaft 2 will not fall off in the rotor 12. A connecting strip 44 is arranged in the receiving groove 22, and a tooth block 441 is provided on the connecting strip 44. The tooth block 441 will be 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, and 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 and the rotor 12 drives the rotating shaft 2 to rotate, when the rotor 12 rotates, the pressing block 31 is affected by the centrifugal force and will move downward in the connecting chamber 121. A pressing connecting arm 32 is provided at the bottom of the pressing block 31. The downward moving pressing block 31 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. A connecting hole 331 is provided in the rotating connecting arm 33. The connecting hole 331 connects the rotating connecting arm 33 in the connecting chamber 121. The connecting hole 331 is sleeved on the connecting rod arranged on the connecting chamber 121, so that the rotating connecting arm 33 can rotate. When the pressing connecting arm 32 squeezes the rotating connecting arm 33, the rotating connecting arm 33 rotates under the influence of the connecting hole 331, so as to push the clamping arm 34 upward, making the clamping arm 34 move upward. The clamping arm 34 is limited by the connecting chamber 121 and can only move upward under the thrust of the rotating connecting arm 33. According to 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 upwardly pushed clamping arm 34 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.

[0035] The rotating shaft 2 includes a rotating shaft housing 24 which is used to fix the central rod 4, and the receiving groove 22 accommodates the central rod 4. The receiving groove 22 is formed in the rotating shaft housing 24 and is used to accommodate the connecting strip 44 to ensure that the connecting strip 44 can extend outwards, so as to protrude from the outside of the rotating shaft housing 24, and thus can contact the clamping arm 34. The central rod 4 is provided in the rotating shaft housing 24 and is used to drive the connecting strip 44 to extend outwards or contract inwards. As shown in Figure 6 the content shown, a connecting seat 41 is provided on the central rod 4, a first connecting rotating shaft 411 is connected in the connecting seat 41, and one end of a pushing arm 42 is connected to the first connecting rotating shaft 411. The pushing arm 42 can rotate on the first connecting rotating shaft 411 on the connecting seat 41, so as to push the connecting strip 44 upwards. Since the connecting strip 44 is limited by the receiving groove 22, when being pushed, it is ensured that the movement track of the connecting strip 44 can only be in the receiving groove 22. The other end of the pushing arm 42 is connected to a second connecting rotating shaft 43. The function of the second connecting rotating shaft 43 is to enable the connecting strip 44 to be adapted to the connection of the pushing arm 42. The second connecting rotating shaft 43 is used to adjust the connection angle between the connecting strip 44 and the pushing arm 42, and the second connecting rotating shaft 43 is provided on the connecting strip 44.

[0036] Thus, the first embodiment can be obtained. When the motor is started, the rotor 12 begins 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 affected by the centrifugal force. Since the direction of the centrifugal force is away from the rotation center, the pressing block 31 will move vertically downwards in the connecting chamber 121. When the pressing block 31 moves downwards, the pressing connecting arm 32 connected thereto also moves downwards accordingly and exerts a squeezing 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 squeezed 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, the end thereof connected to the clamping arm 34 will lift upwards, thereby pushing the clamping arm 34 to move upwards. Since the clamping arm 34 is restricted by the limiting structure in the connecting chamber 121 and can only move upwards, when the clamping arm 34 moves upwards, its end will accurately be clamped between the tooth blocks 441 on the connecting strip 44. Through this tight clamping fit, the connecting strip 44 is firmly fixed, and further the rotating shaft 2 is firmly fixed inside the rotor 12, ensuring that the rotating shaft 2 will not fall off or shake during the operation of the motor.

[0037] The central rod 4 also has the function of adjusting the position of the connecting bar 44 in the whole structure. When it is necessary to adjust the extending length or position of the connecting bar 44, by applying a certain external force to the central rod 4 (for example, in some specific designs, the external force can be applied by connecting an external control mechanism to the central rod 4), the central rod 4 will move axially. As the central rod 4 moves, the connecting seat 41 mounted on it will also move synchronously. Since the connecting seat 41 is connected to the push arm 42 through the first connecting rotating shaft 411, the movement of the connecting seat 41 will drive the push arm 42 to rotate around the first connecting rotating shaft 411. During the rotation of the push arm 42, the other end of it is connected to the connecting bar 44 through the second connecting rotating shaft 43, thereby pushing the connecting bar 44 to extend or contract in the receiving groove 22. In this way, the position of the connecting bar 44 can be flexibly adjusted according to the actual working requirements, so that the rotating shaft 2 can be fixed in the rotor 12. Such a connection method of the whole rotating shaft 2 effectively eliminates the connection through the coupling and the working machine, thereby solving the problems caused by the coupling.

[0038] Please refer to Figures 7-11 As shown, a connecting groove is formed on the central rod 4, and a bearing shaft 51 is arranged in the connecting groove. The bearing shaft 51 can rotate in the connecting groove. The bearing shaft 51 is provided with a first insertion tooth 511 and a first adjusting tooth 512. The length of the first adjusting tooth 512 is longer than that of the first insertion tooth 511. The first insertion tooth 511 and the first adjusting tooth 512 are arranged in a circumferential array on one side of the bearing shaft 51. The rotating shaft 2 further includes a sealing plate 23 arranged on the rotating shaft housing 24. The sealing plate 23 is provided with a circular center opening that matches the size of the central rod 4 to ensure that the central rod 4 can move on the sealing plate 23. The second insertion tooth 52 is used to cooperate with the first insertion tooth 511. The second adjusting tooth 53 is engaged with the first adjusting tooth 512, and the second adjusting tooth 53 and the second insertion tooth 52 are arranged in a staggered manner. The tooth peak of the second insertion tooth 52, a second insertion tooth 52 and a second adjusting tooth 53 are arranged on the side of the sealing plate 23 opposite to the bearing shaft 51. The second insertion tooth 52 and the second adjusting tooth 53 are arranged to match the positions of the first insertion tooth 511 and the first adjusting tooth 512. Such an arrangement can also ensure that when the first insertion tooth 511 and the second insertion tooth 52 are engaged, the first adjusting tooth 512 is engaged in the middle of the tooth surface of the second adjusting tooth 53 and will not reach the bottom of the tooth of the second adjusting tooth 53. In addition, the height of the first insertion tooth 511 is the same as that of the second insertion tooth 52. The advantage of such a design is that when the first insertion tooth 511 is inserted into the insertion opening 521, the distance between the bearing shaft 51 and the sealing plate 23 can be reduced.

[0039] There are at least two second insertion teeth 52, and the gap therebetween is an insertion opening 521. The width of the insertion opening 521 is the same as that of the first insertion tooth 511. The insertion opening 521 allows the first insertion tooth 511 to be inserted, thereby shortening the distance between the bearing shaft 51 and the sealing plate 23.

[0040] As Figure 9 shown, a moving groove 532 is formed in the sealing plate 23. The moving groove 532 is used for the anti-compression spring 533 to ensure that the anti-compression spring 533 can move in the moving groove 532. The anti-compression spring 533 is provided on the moving groove 532. The anti-compression spring 533 is used to enable the second adjusting tooth 53 to achieve a reset effect and also gives the function of moving the second adjusting tooth 53. The top of the anti-compression spring 533 and the second adjusting tooth 53 are provided with a baffle 531 at the bottom of the second adjusting tooth 53. The baffle 531 is used to prevent the second adjusting tooth 53 from detaching from the moving groove 532. The baffle 531 is clamped in the moving groove 532. Such a design allows the second adjusting tooth 53 to move along 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 anti-compression spring 533 is compressed. To meet the above requirements, the height of the anti-compression spring 533 plus the height of the second adjusting tooth 53 should be higher than the height of the second insertion tooth 52. In addition, the anti-compression spring 533 is arranged in a circular shape on the second adjusting tooth 53.

[0041] On the other side of the sealing plate 23 where the second insertion tooth 52 is provided, there is a spring baffle 54. A reset spring 55 is provided on the spring baffle 54. The spring baffle 54 not only bears the reset spring 55 but also blocks the anti-compression spring 533. The material of the spring baffle 54 is selected as a material with anti-compression and wear resistance. The central rod 4 is inserted into the sealing plate 23 and the reset spring 55. A push button 56 is provided at the end of the central rod 4. During installation, the rotating shaft 2 is inserted into the rotor 12, passes through the rotor 12, and finally is inserted into the braking mechanism 14 and the encoder 15. The braking mechanism 14 and the encoder 15 block the push button 56. When the rotating shaft 2 is squeezed forcefully, the push button 56 receives a reaction force and drives the central rod 4 to move inward. At this time, the reset spring 55 is in a compressed state, thereby driving the bearing shaft 51 to separate from the sealing plate 23.

[0042] From this, a second embodiment can be obtained. When the rotating shaft 2 is inserted into the rotor 12 and passes through the rotor 12, and 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 push button 56. When the rotating shaft 2 is squeezed forcefully, the push button 56 receives a reaction force and drives the center rod 4 to move inward. At this time, the return spring 55 is in a compressed state, thereby driving the bearing shaft 51 to separate from the sealing plate 23. At this time, the second adjusting tooth 53 loses the pressing force of the first adjusting tooth 512, and thus follows the first adjusting tooth 512 to move according to the rebound force of the compression spring 533. At this time, the first insertion tooth 511 is out of the control of the insertion opening 521, and the first adjusting tooth 512 will slide to the bottom of the tooth surface of the second adjusting tooth 53 according to the tooth surface of the second adjusting tooth 53. The first adjusting tooth 512 drives the bearing shaft 51 to rotate slightly, and the rotation angle is the distance from the tooth surface to the tooth bottom of the second adjusting tooth 53. Then, the rotating shaft 2 is released. At this time, the center rod 4 is not subject to the thrust force towards the inside of the motor during installation. The return spring 55 rebounds to drive the push button 56 to drive the center rod 4 to move back to its original position. The displacement amount of the rebound of the push button 56 is carried by the cavity. The center rod 4 moving back to its original position drives the bearing shaft 51 to move closer to the sealing plate 23. At this time, due to the influence of the rotational displacement of the bearing shaft 51, the first insertion tooth 511 changes from the position inserted into the insertion opening 521 to the second insertion tooth 52, thereby limiting the center rod 4 from returning to its previous position. Since the center rod 4 moves backward and is locked by being clamped by the first insertion tooth 511 on the second insertion tooth 52, the rotation of the push arm 42 is driven, and the connecting bar 44 is pushed outwards and clamped and fixed.

[0043] When it is necessary to disassemble the center rod 4, only need to push the rotating shaft 2 into the motor again and repeat the installation steps. The bearing shaft 51 moves away from the sealing plate 23, and the first insertion tooth 511 is out of the control of the second insertion tooth 52. The second adjusting tooth 53 continues to move following the movement of the first adjusting tooth 512. Thus, the first adjusting tooth 512 drives the bearing shaft 51 to rotate, so that the first adjusting tooth 512 slides to the bottom of the tooth surface of the second adjusting tooth 53 under the influence of the second adjusting tooth 53, so that the first insertion tooth 511 can be smoothly clamped in the insertion opening 521, reset the positions of the bearing shaft 51 and the sealing plate 23, thereby retracting the outwardly pushed connecting bar 44, releasing the clamping with the clamping mechanism 3, and then pulling out the connecting bar 44.

[0044] At least two accommodating grooves 22 are provided on the rotating shaft housing 24, specifically eight, which are arranged in a circular array on the outer side of the rotating shaft housing 24. Refer to Figure 3As shown, such a design can ensure the stability of the connection of the rotating shaft 2 as much as possible during installation, prevent accidents during work caused by unstable connection on one side, and correspondingly, the number of connection bars 44 is also at least two. Knurling is provided on the rotating shaft housing 24, and a receiving groove 22 is provided in the knurling.

[0045] The motor housing 1 also includes a bearing 13 provided on the rotating shaft 2, a braking mechanism 14 provided on the rotating shaft 2, and an encoder 15 provided on the rotating shaft 2.

[0046] When the assembly structure of the servo motor is in use, first insert the rotating shaft 2 into the rotor 12 and pass it through the rotor 12, and finally insert the braking mechanism 14 and the encoder 15. The cavities in the braking mechanism 14 and the encoder 15 are adapted to the installation of the rotating shaft 2 and at the same time block the pressing button 56. Exert force on the rotating shaft 2, the pressing button 56 drives the center rod 4 to move inward under the reaction force, the return spring 55 is compressed, the bearing shaft 51 is separated from the sealing plate 23, and the second adjusting tooth 53 moves following the first adjusting tooth 512 under the action of the compression spring 533, and the first inserting tooth 511 disengages from the insertion port 521. After the first adjusting tooth 512 drives the bearing shaft 51 to rotate slightly, release the rotating shaft 2, and the center rod 4 drives the bearing shaft 51 to move towards the sealing plate 23 under the rebound of the return spring 55. The first inserting tooth 511 moves into the second inserting tooth 52, locks the center rod 4, and then drives the pushing arm 42 to rotate, pushing the connection bar 44 outwards and engaging and fixing it with the engaging mechanism 3.

[0047] After the motor is started, the rotor 12 drives the rotating shaft 2 to rotate at a high speed. The pressing block 31 in the connection bin 121 moves downward under the action of centrifugal force, driving the pressing connection arm 32 to move downward synchronously and squeeze the rotating connection arm 33. The rotating connection arm 33 rotates around the connecting rod in the connection hole 331, pushing the engaging arm 34 to move upward. The engaging arm 34 is limited by the connection bin 121 and can only move upward, and its end is caught between the tooth blocks 441 on the connection bar 44, fixing the connection bar 44, thereby firmly fixing the rotating shaft 2 inside the rotor 12. In addition, the center rod 4 can drive the connection bar 44 to extend or contract in the receiving groove 22 through the connection seat 41, the first connecting rotating shaft 411, the pushing arm 42, and the second connecting rotating shaft 43 to adjust the position.

[0048] When disassembling, the rotating shaft 2 is pushed into the motor again, the bearing shaft 51 moves away from the sealing plate 23, the first insertion tooth 511 is released from the control of the second insertion tooth 52, and the second adjustment tooth 53 continues to move following the first adjustment tooth 512. The first adjustment tooth 512 drives the bearing shaft 51 to rotate, causing it to slide to the bottom of the tooth under the influence of the second adjustment tooth 53, so that the first insertion tooth 511 can be smoothly inserted into the insertion opening 521. The bearing shaft 51 and the sealing plate 23 return to their initial positions, the outwardly pushed connecting bar 44 retracts, the engagement with the engaging mechanism 3 is released, and then the connecting bar 44 can be pulled out. The rotating shaft housing 24 is provided with a plurality of receiving grooves 22 (such as eight arranged in a circular array) and cooperates with the corresponding number of connecting bars 44 to ensure the connection stability. The bearing 13, the braking mechanism 14, and the encoder 15 in the motor housing 1 cooperate to ensure the operation of the servo motor.
