[0002] An encoder is a precision electronic device that feeds back the displacement data of a motor to a servo driver for comparison to achieve positioning. When installing an encoder, it needs to be fixed to the rotating shaft of the servo motor so that the encoder can record the data of the motor, and a fixing bracket is required during the fixing process.

[0004] During the implementation of the above solution, it is possible to optimize the bracket structure and save material costs while ensuring sufficient mechanical strength. However, during the implementation of the above solution, it is difficult to reinforce the encoder. If a certain screw for fixing the encoder becomes loose after long-term use, due to uneven stress, the encoder may tilt to a certain extent, resulting in friction between the encoder and the coupling and causing damage to both. For this reason, we provide a servo motor encoder fixing bracket to solve the above problems. Summary of the Utility Model

[0026] The embodiment of the present utility model provides a fixed bracket for a servo motor encoder.
[0027] Please refer to Figure 1 , which includes a servo motor 1. A protective outer cover 13 is installed on the outer surface of the servo motor 1. The servo motor 1 is a prior art and will not be elaborated too much in this application. The protective outer cover 13 is fixed on the servo motor 1 by screws, playing a role in protecting the external bracket of the servo motor 1 and the encoder 7, and ensuring that the encoder 7 can operate normally.
[0028] Please refer to Figure 2 and Figure 3 , a fixed mounting pad 2 is arranged outside the servo motor 1. A set of fixed screw holes 12 are opened on the outer surfaces of the servo motor 1 and the fixed mounting pad 2. The fixed screw holes 12 on the surfaces of the servo motor 1 and the fixed mounting pad 2 are mutually adapted. Workers can fix the fixed mounting pad 2 on the servo motor 1 by turning the screws, thereby installing the fixed bracket.
[0029] The outer surface of the fixed mounting pad 2 is fixedly connected with a fixed connecting plate 3. Inside the fixed connecting plate 3, a coupling 11 is provided. The coupling 11 is sleeved on the rotating shafts of the servo motor 1 and the encoder 7. The coupling 11 can connect two shafts (the driving shaft and the driven shaft) in different mechanisms to rotate together to transmit torque, and has the functions of buffering, damping and improving the dynamic performance of the shafting. Through the setting of the coupling 11, the rotating shafts of the servo motor 1 and the encoder 7 can be fixedly connected together, enabling the encoder 7 to detect data of the servo motor 1. The spacing distance of the fixed connecting plate 3 is greater than that of the coupling 11, which is convenient for installing the coupling 11.
[0030] The end of the fixed connecting plate 3 is fixedly connected with a fixed ring 4. An encoder 7 is arranged outside the fixed ring 4. A cable 8 is fixedly connected inside the encoder 7. Both the encoder 7 and the cable 8 are prior arts, and will not be elaborated too much in this application. The encoder 7 can feedback the displacement data of the motor back to the servo driver for comparison to achieve positioning. It mostly contains optical precision components and needs to be handled with care during installation.
[0031] Please refer to Figure 4 , a set of special-shaped screw holes 9 adapted to the encoder 7 are opened on the top surface of the fixed ring 4, and a jack 10 adapted to the encoder 7 is opened inside the fixed ring 4. The special-shaped screw hole 9 is a special screw hole adapted to the M4 starting-head screw. There is also a screw hole on the bottom surface of the encoder 7 that is consistent with the special-shaped screw hole 9. The staff can fix the encoder 7 in the fixed ring 4 through the M4 starting-head screw. The jack 10 leaves space for the installation of the rotating shaft of the encoder 7.
[0032] A cavity 5 is opened inside the fixed ring 4. A set of reinforcing mechanisms 6 for reinforcement effect are arranged inside the cavity 5. The inner wall of the cavity 5 is demagnetized to prevent the magnetic adsorption effect between the permanent semi-magnetic ring 601 and the fixed ring 4 from reducing the adsorption force between the two permanent semi-magnetic rings 601.
[0033] The reinforcing mechanism 6 includes a permanent semi-magnetic ring 601 slidably connected to the cavity 5. The cavity 5 can limit the permanent semi-magnetic ring 601, so that the permanent semi-magnetic ring 601 can only slide in the cavity 5, preventing the permanent semi-magnetic ring 601 from tilting and affecting the reinforcement effect of the reinforcing semi-ring 603 on the encoder 7. The magnetic adsorption effect between the two permanent semi-magnetic rings 601 is sufficient to enable the reinforcing semi-ring 603 to stably reinforce the encoder 7.
[0034] A set of connecting sliding rods 602 are fixedly connected to the top surface of the permanent semi-magnetic ring 601. The diameter of the permanent semi-magnetic ring 601 is slightly smaller than that of the encoder 7 to ensure that when the two permanent semi-magnetic rings 601 are adsorbed together, the reinforcing semi-ring 603 can tightly fix the encoder 7, provide fixed support for the encoder 7, and improve the fixing effect of the device on the encoder 7.
[0035] Above the fixed ring 4, a reinforcing semi-ring 603 is provided. Each connecting slide rod 602 is fixedly connected to the reinforcing semi-ring 603. The inner wall of the reinforcing semi-ring 603 is covered with a layer of rubber pad, which can play a certain buffering role during the process of the reinforcing semi-ring 603 reinforcing the encoder 7, and avoid damaging the surface of the encoder 7 during the reinforcement process by the reinforcing semi-ring 603.
[0036] A set of sliding holes 604 are opened on the top surface of the fixed ring 4. Each connecting slide rod 602 is slidably connected to the sliding hole 604. The sliding hole 604 provides space for the transmission of the connecting slide rod 602. When the permanent semi-magnetic ring 601 slides inside the cavity 5, it can drive the connecting slide rod 602 to move in the sliding hole 604. The movement of the connecting slide rod 602 can drive the movement of the reinforcing semi-ring 603, thereby opening the reinforcing semi-ring 603, facilitating the installation and disassembly of the encoder 7. Multiple connecting slide rods 602 can improve the connection stability between the permanent semi-magnetic ring 601 and the reinforcing semi-ring 603.
[0037] The outer surface of the permanent semi-magnetic ring 601 is fixedly connected with a control pull rod 605. The control pull rod 605 penetrates through the fixed ring 4 and is slidably connected to the fixed ring 4. When the staff installs or disassembles the encoder 7, they only need to pull the control pull rod 605 to cancel the reinforcing effect of the reinforcing semi-ring 603 on the encoder 7, facilitating the maintenance and replacement of the encoder 7.
[0038] Working principle: When the staff wants to install the encoder 7 on the servo motor 1, first pull the control pull rod 605, place the encoder 7 into the fixed ring 4, and then release the hand. The permanent semi-magnetic rings 601 will be attracted to each other under the action of magnetic force. The permanent semi-magnetic ring 601 can drive the connecting slide rod 602 to slide inside the sliding hole 604, and the connecting slide rod 602 drives the reinforcing semi-ring 603 to fix the encoder 7. Then, fix the encoder 7 on the fixed ring 4 with M4 start-head screws, install the coupling 11 on the rotating shaft of the encoder 7, and then install the fixed mounting pad 2 on the servo motor 1 through the fixed screw holes 12 and fix the coupling 11 on the rotating shaft of the servo motor 1 to complete the installation of the encoder 7, improving the fixing effect of the bracket on the encoder 7 and protecting the operation safety of the encoder 7.
