[0002] As an actuator, the servo motor can convert the received electrical signal into the angular displacement or angular acceleration output on the motor shaft and is widely used in the field of automation. The servo motor encoder is installed on the servo motor and is a sensor used to measure the magnetic pole position and the servo motor's rotation angle and speed.
[0003] The existing publication number CN218678748U discloses an integrated servo motor shaft grounding device, including a fixed ring and a conductive fiber, the fixed ring is provided with a plurality of conductive fiber plug holes on one side facing the annular center thereof, the plurality of conductive fiber plug holes are evenly distributed around the annular center of the fixed ring and extend radially along the fixed ring, a conductive fiber is inserted into each conductive fiber plug hole, the conductive fiber is exposed from the conductive fiber plug hole, and an annular riveting groove arranged around the annular center of the fixed ring is formed on one axial side of the fixed ring. The utility model makes the motor shaft grounding device more concise in structure and more convenient to manufacture.
[0004] It has been found that the above-mentioned device still has some shortcomings. First, when using the fixing ring, the fixing ring needs to be put on the outer periphery of the motor shaft. If other components have been fixed to the rotor of the servo motor before using the above-mentioned device, although the fixing ring is flexible, it has limited expansion and contraction. Long-term use in this state will destroy the flexibility, and the fixing ring is inconvenient to install and disassemble.
[0005] Therefore, it is necessary to provide a new integrated servo motor shaft grounding device to solve the above technical problems. Utility Model Content
[0006] In order to solve the above technical problems, the utility model provides an integrated servo motor shaft grounding device.
[0007] The utility model provides an integrated servo motor shaft grounding device comprising: an elastic clamp, an anti-slip pad is fixed on the inner side of the elastic clamp, a through slot is provided on the elastic clamp, an elastic clamp ring is provided above the through slot, an elastic card is inserted on the through slot, an installation slot is provided on the elastic card, an arc seat is fixed on one end of the elastic card, the other end of the elastic card is fixed to the elastic clamp ring, a conductive area is provided on the inner side of the elastic clamp ring, and a conductive tube is fixed on the side of the conductive area.
[0008] Preferably, the elastic clamp and the elastic clamp ring are movably connected via an elastic card.
[0009] Preferably, the elastic clamping ring is provided with evenly distributed groove 1 and groove 2.
[0010] Preferably, there are multiple conductive tubes.
[0011] Preferably, the elastic card is located at the edge of the elastic clamp ring.
[0012] Preferably, the conductive tube passes through groove one and groove two and extends into the installation groove.
[0013] Compared with the related art, the integrated servo motor shaft grounding device provided by the utility model has the following beneficial effects:
[0014] When in use, just clamp the flexible elastic clamp on the outer periphery of the motor shaft of the servo motor. The anti-slip pad on the inside of the elastic clamp will prevent the elastic clamp from sliding on the outer periphery of the motor shaft. At this time, the elastic clamp should be located on the rotating rotor. Since the elastic clamp has a certain elasticity, the elastic clamp will be clamped on the rotor, and the rotor drives the elastic clamp to rotate. A conductive area is provided on the inside of the elastic clamp to conduct the induced electricity to the elastic clamp, which will conduct the induced electricity on the rotor. When the servo motor shaft grounding device needs to be replaced, the disassembly can be completed by simply moving the elastic clamp and the two sides of the elastic clamp, and the inner wall of the elastic clamp is in direct contact with the rotor of the servo motor, which can better conduct the induced electricity.

[0019] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.
[0020] Please refer to Figures 1 to 3 ,in, Figure 1 This is a schematic diagram of the overall structure of the integrated servo motor shaft grounding device provided by the utility model; Figure 2 A bottom view structural diagram of the integrated servo motor shaft grounding device provided by the utility model; Figure 3This is a schematic top view of the structure of the integrated servo motor shaft grounding device provided by the utility model.
[0021] In the specific implementation process, Figures 1 to 3 As shown, it includes an elastic fixture 1, an anti-skid pad 12 is fixed on the inner side of the elastic fixture 1, and the anti-skid pad 12 is used to fix the elastic fixture 1 to prevent the elastic fixture 1 from rotating on the motor shaft of the servo motor. A through groove 11 is provided on the elastic fixture 1, and an elastic snap ring 2 is provided above the through groove 11. The inner ring of the elastic fixture 1 is larger than the inner ring of the elastic snap ring 2. This arrangement can make the elastic fixture 1 and the elastic snap ring 2 better fixed to the outer ring of the motor shaft and the rotor of the servo motor respectively. An elastic card 13 is inserted in the through groove 11, and an installation groove 25 is provided on the elastic card 13. The other end of the elastic card 13 is fixed to the elastic snap ring 2. A conductive area 23 is provided on the inner side of the clamp 2, and a conductive tube 24 is fixed on the side of the conductive area 23. The establishment of the conductive area 23 can conduct the induced electricity generated on the rotor when the servo motor is working to the elastic clamp 1 through the conductive tube 24. The elastic clamp 1 is grounded through a wire to conduct the induced electricity to the ground. The elastic clamp 1, the elastic clamp 2, and the elastic card 13 are flexible, wherein the elastic clamp 1, the elastic clamp 2 and the elastic card 13 are preferably conductive rubber. The device is installed on the motor shaft of the servo motor to form an integrated connection, and when the servo motor shaft rotates, the above device will not affect the normal operation of the servo motor.
[0022] refer to Figure 1 to Figure 2 As shown, the elastic clamp 1 and the elastic snap ring 2 are movably connected through the elastic card 13. The elastic snap ring 2 is provided with evenly distributed grooves 1 21 and 22. There are multiple conductive tubes 24. The conductive tubes 24 pass through the grooves 1 21 and 22 and extend into the mounting groove 25. The arc of the open loop of the elastic clamp 1 and the elastic snap ring 2 is relatively large. When rotating, the elastic card 13 is not easy to separate from the mounting groove 25. The elastic card 13 is located at the edge of the elastic snap ring 2. When the servo motor is working and the rotor on the servo motor rotates, the conductive tube 24 rotates tangent to the mounting groove 25 and will not separate.
[0023] refer to Figure 3 As shown, an arc seat 3 is fixed to one end of the elastic card 13 , and the arc seat 3 can limit the elastic card 13 in the through slot 11 .
[0024] The working principle provided by the utility model is as follows: when in use, it is only necessary to clamp the flexible elastic clamp 1 on the outer periphery of the motor shaft of the servo motor, and the anti-slip pad 12 on the inner side of the elastic clamp 1 will prevent the elastic clamp 1 from sliding on the outer periphery of the motor shaft. At this time, the elastic clamp ring 2 should be located on the rotating rotor. Since the elastic clamp ring 2 has a certain elasticity, the elastic clamp ring 2 will be clamped on the rotor, and the rotor drives the elastic clamp ring 2 to rotate. A conductive area 23 is provided on the inner side of the elastic clamp ring 2 to conduct the induced electricity to the elastic clamp 1. The elastic clamp 1 is grounded through a wire, and the induced electricity on the rotor will be conducted to the ground.
