Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a coupling mechanism and a servo motor. Background Technology

[0002] Servo motors play an irreplaceable role in precision mechanical equipment testing, high-end equipment research and development, and intelligent manufacturing. In common mechanical transmission architectures, the output shaft of a servo motor is typically connected to the equipment drive end via a coupling.

[0003] In dynamic testing scenarios, the ease and stability of connecting the servo motor output shaft to the device drive end play a decisive role in the debugging, maintenance, and performance optimization of the device throughout its entire life cycle.

[0004] However, since the drive end and the servo motor output shaft are mostly connected using a splined plug-in structure, the two are tightly coupled and some structures are nested within each other. When it is necessary to disconnect the connection, due to the space constraints of the plug-in structure and the assembly characteristics, it is often necessary to disassemble the servo motor or related equipment components first. This process not only involves many cumbersome operating steps, significantly extending the debugging time, but also frequently uses professional disassembly tools, which can easily cause damage to the equipment, increase the equipment failure rate and maintenance costs, and seriously restrict the efficient progress of testing and experimentation, making equipment debugging and adjustment extremely difficult.

[0005] In view of this, a coupling mechanism and a servo motor are proposed. Utility Model Content

[0029] In a preferred embodiment of the coupling mechanism of this utility model, the end of the second connecting rod near the pusher plate is arc-shaped.

[0030] The beneficial effects of the coupling mechanism of this utility model are as follows: By sliding the second connecting rod, the short column slides until it aligns with the arc groove, and the insertion end separates from the drive end of the device.

[0040] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0041] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0043] Example 1, referring to Figures 1 to 4 This is the first embodiment of the present invention. This embodiment provides a coupling mechanism, including a first connecting member 1, which includes a first connecting rod 11 and a connecting end 111 disposed at the end of the first connecting rod 11. The first connecting rod 11 is provided with a sliding groove 12 and an arc groove 121; the connecting end 111 is used to connect with the output shaft of a servo motor.

[0044] The second connecting member 2 includes a second connecting rod 21, a sliding column 22 disposed on the second connecting rod 21, and a short column 23 disposed on the second connecting rod 21; there are two short columns 23 disposed symmetrically on the second connecting rod 21.

[0045] The third connector 3 is disposed on the second connector 2. The third connector 3 is provided with a plug-in end 34, which is used to connect with the drive end of the device.

[0046] Specifically, the sliding column 22 is slidably disposed inside the sliding groove 12, and the length of the short column 23 is shorter than the length of the sliding column 22. The length of the short column 23 matches the depth of the arc groove 121, and the short column 23 can slide into the arc groove 121.

[0047] Furthermore, the arc groove 121 and the slide groove 12 are connected, with the arc groove 121 located at one end of the slide groove 12 near the connecting end 111.

[0048] In the initial state, the output shaft of the servo motor is connected to the connecting end 111, and the sliding column 22 and the short column 23 are located in the sliding groove 12. The sliding column 22 is located at the end of the sliding groove 12 away from the connecting end 111, and the plug-in end 34 is a flower groove or a square groove, which is connected to the drive end of the device.

[0049] When disconnecting the output shaft of the servo motor from the drive end of the device, first slide the second connecting rod 21 so that the sliding column 22 and the short column 23 slide together in the sliding groove 12. When the short column 23 slides to align with the arc groove 121, the plug end 34 separates from the drive end of the device. Rotate the second connecting rod 21 so that the second connecting rod 21 rotates around the sliding column 22 as the rotation axis. The short column 23 slides into the arc groove 121. By increasing the rotation angle of the second connecting rod 21, the short column 23 disengages from the arc groove 121. At this time, the first connecting member 1 and the second connecting member 2 can become perpendicular. Therefore, it is convenient to disconnect the servo motor from the drive end of the device. After disconnection, the rotation of the second connecting rod 21 can achieve spatial avoidance, which is convenient for debugging the device and provides a larger operating space. It solves the problem of disassembling the servo motor and the drive end of the device that need to be set coaxially, improves the efficiency of disassembly, and can effectively reduce the debugging time of the device. The process is simple and convenient.

[0050] After the equipment is debugged, when it is necessary to connect the output shaft of the servo motor to the drive end of the equipment, rotate and slide the second connecting rod 21 so that the short column 23 can be aligned with the arc groove 121. After the second connecting rod 21 is deflected, the short column 23 can be aligned with the slide groove 12. At this time, the second connecting rod 21 and the first connecting rod 11 are in a straight state, and the plug end 34 is aligned with the drive end of the equipment. By sliding the second connecting rod 21, the sliding column 22 and the short column 23 slide in the slide groove 12 until the sliding column 22 touches the end of the slide groove 12. The plug end 34 is plugged into the drive end of the equipment to complete the transmission connection.

[0051] When the servo motor control device rotates, since the short column 23 and the sliding column 22 are both located in the slide groove 12, the rotation between the second connecting rod 21 and the first connecting rod 11 can be avoided, thus ensuring normal drive.

[0052] Preferably, the first connecting member 1 further includes a disc 13 disposed on the first connecting rod 11; the disc 13 is fixedly disposed on the outer wall of the first connecting rod 11.

[0053] The disc body 13 is provided with a pusher 4; the pusher 4 includes a spring 41 provided on the disc body 13 and a pusher disc 42 provided at the end of the spring 41.

[0054] Spring 41 is fixedly mounted on disc 13, and spring 41 is fixedly connected to push disc 42.

[0055] Preferably, the end of the pusher plate 42 is in contact with one end of the second connecting rod 21;

[0056] The pusher plate 42 is slidably disposed outside the first connecting rod 11.

[0057] It should be noted that the end of the second connecting rod 21 near the push plate 42 is arc-shaped.

[0058] In use, the elastic force provided by the spring 41 causes the end of the second connecting rod 21 to be abutted, giving it a tendency to move away from the first connecting member 1. Therefore, when the servo motor and the drive end of the device are in a transmission connection state, the thrust provided by the spring 41 can maintain the plug-in connection between the plug-in end 34 and the drive end of the device. The end of the second connecting rod 21 is arc-shaped, which allows the short column 23 to abut against the push plate 42 through the arc structure when aligned with the arc groove 121, so that the second connecting rod 21 can rotate. When the second connecting rod 21 and the first connecting rod 11 are perpendicular, the thrust provided by the spring 41 causes the push plate 42 to abut against the outer wall of the first connecting rod 11, which can keep the second connecting rod 21 perpendicular to the first connecting rod 11, making it easier to maintain clearance space for people to debug the device.

[0059] Example 2, refer to Figures 1-4 This is the second embodiment of the present utility model. Unlike the previous embodiment, the first connecting rod 11 is provided with a cylindrical groove 122, which is located at the end of the sliding groove 12 away from the connecting end 111.

[0060] The diameter of the cylindrical groove 122 is larger than the diameter of the sliding column 22; the diameter of the short column 23 matches the width of the sliding groove 12.

[0061] When the sliding column 22 is located in the cylindrical groove 122, the sliding column 22 can move within the cylindrical groove 122. Since the diameter of the short column 23 matches the width of the groove 12, a slight angular deflection can occur between the second connecting rod 21 and the first connecting rod 11.

[0062] Specifically, the second connector 2 is provided with a rotating groove 24;

[0063] The third connecting member 3 includes a third connecting rod 31 and a rotating shaft 32 disposed on the third connecting rod 31;

[0064] The rotating shaft 32 and the rotating groove 24 are rotatably connected;

[0065] The plug end 34 is located at the end of the third connecting rod 31 that is away from the second connecting rod 21.

[0066] Furthermore, the second connecting rod 21 is provided with a movable opening 25;

[0067] The third connecting rod 31 is provided with a limiting block 33;

[0068] The limiting block 33 is movably disposed within the movable opening 25, and the size of the limiting block 33 is smaller than the size of the movable opening 25.

[0069] It should be noted that the rotating shaft 32 and the sliding column 22 are vertically distributed.

[0070] In practical use, the output shaft of the servo motor and the drive end of the device are often difficult to keep coaxial, or there may be a slight deviation. The deviation can easily cause instability in the operation of the device, easily generate vibration, and damage the coupling mechanism. To address this, due to the cylindrical groove 122, the second connecting rod 21 and the first connecting rod 11 can produce a slight deflection. Since the size of the limiting block 33 is smaller than the size of the movable opening 25, the limiting block 33 can move slightly within the movable opening 25. Furthermore, since the rotating shaft 32 and the rotating groove 24 are rotatably connected, the second connecting rod 21 and the third connecting rod 31 can produce a slight deflection. Also, since the rotating shaft 32 and the sliding column 22 are vertically distributed, the deflection direction between the first connecting rod 11 and the second connecting rod 21 and the deflection direction between the second connecting rod 21 and the third connecting rod 31 are perpendicular to each other. Therefore, even when there is a certain axial offset between the output shaft of the servo motor and the drive end of the device, shaft connection and shaft transmission can still be performed, ensuring stability during the transmission process.

[0071] The rest of the structure is the same as in Example 1.

[0072] Example 3, referring to Figures 1-5 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a servo motor, including a coupling mechanism and a motor body 5. The output end of the motor body 5 and the connection end 111 are connected.

[0073] The rest of the structure is the same as in Example 2.

[0074] In use, the coupling mechanism allows the operator to easily separate and connect the output end of the motor body 5 and the drive end of the equipment. After the transmission is separated, there is a large clearance space, which makes it convenient for the operator to debug the equipment. The coupling mechanism can make transmission connections between different shafts, and the coupling mechanism also has a certain buffering capacity. For example, if an error occurs during debugging and the coupling mechanism is subjected to an axial force of the motor body 5, it can slide to a certain extent through the sliding of the short column 23 and the sliding column 22 in the sliding groove 12 to protect the motor body 5.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
