During the rotation of the encoder body 3, The arc arm 41 descends along the spiral groove 21, and the arc arm 41 drives the locking plate 5 to move, so that the locking pawl 51 of the locking plate 5 is locked with the locking ratchet 11. At this time, the installation of the mounting base 1 and the encoder body 3 is completed, and the connection between the mounting base 1 and the encoder body 3 is stable and reliable; when the encoder body 3 needs to be disassembled, it is only necessary to continue to rotate the encoder body 3, so that the arc arm 41 drives the locking plate 5 to move, thereby separating the locking ratchet 11 from the locking pawl 51, that is, the encoder body 3 can be separated from the mounting base 1.

[0020] In the embodiment of the present invention, a high-precision inductive encoder that is easy to install is described, wherein the cross-sectional shapes of the mounting seat 1, the mounting platform 2, the encoder body 3, the connecting boss 4 and the locking plate 5 are all circular; the cross-sectional shape of the locking ratchet 11 is an arc. In the embodiment of the present invention, a high-precision inductive encoder that is easy to install is described, wherein the arc-shaped arm 41 is provided with an arc-shaped guide groove 42; the top of the locking plate 5 is eccentrically provided with a guide pin 52; the guide pin 52 is movably arranged in the arc-shaped guide groove 42; the mounting seat 1 is provided with a linear guide groove 12 along the diameter direction; a limit pin 53 is provided at the center of the bottom circle of the locking plate 5; the limit pin 53 is movably arranged in the linear guide groove 12; the locking ratchet 11 is arranged at one end of the linear guide groove 12 away from the mounting platform 2.

[0021] Specifically, when the encoder body 3 is mounted on the mounting seat 1, the arc-shaped arm 41 of the connecting boss 4 is first aligned with the opening 22 of the mounting platform 2, and then the connecting boss 4 is inserted into the mounting platform 2 so that the arc-shaped arm 41 enters the top of the spiral groove 21 from the opening 22. Figure 5 As shown, the guide pin 52 is located at the inner end of the arc-shaped guide groove 42, and the floating pin 54 and the limit pin 53 are both located in the linear guide groove 12. At this time, the locking plate 5 is located as a whole at one end close to the mounting platform 2, and the locking ratchet 11 and the locking pawl 51 are far apart, and the locking ratchet 11 and the locking pawl 51 are in a separated state.

[0022] Then start to rotate the encoder body 3 forward. During the rotation of the encoder body 3, the arc arm 41 descends along the spiral groove 21, the guide pin 52 moves along the arc guide groove 42, the floating pin 54 and the limit pin 53 move outward along the linear guide groove 12, until the floating pin 54 moves to the outer end of the linear guide groove 12, the locking ratchet 11 abuts against the locking pawl 51, and the encoder body 3 continues to rotate forward, so that the floating pin 54 enters the arc drive groove 71, until the floating pin 54 enters the blocking step 73, at this time, under the resetting action of the tension spring 63, the blocking step 73 abuts against the floating pin 54, and under the locking action of the locking ratchet 11 and the locking pawl 51, the encoder body 3 cannot rotate reversely; at this time, the installation of the mounting base 1 and the encoder body 3 is completed, and the connection between the mounting base 1 and the encoder body 3 is stable and reliable.

[0023] When the encoder body 3 needs to be disassembled, the encoder body 3 is continuously rotated in the positive direction, so that the floating pin 54 continues to move along the arc driving groove 71 until the floating pin 54 falls into the release pit 74. Figure 6 As shown, at this time, the guide pin 52 is located at the outer end of the arc guide groove 42, and the locking ratchet 11 is separated from the locking pawl 51; then the encoder body 3 is released, and under the action of the tension spring 63, the floating pin 54 moves along the linear drive groove 72 and falls back into the linear guide groove 12, and then the limit pin 53 and the floating pin 54 move along the inner end of the linear drive groove 72, so that the arc arm 41 rotates back to the top position of the spiral groove 21. At this time, the arc arm 41 is taken out from the opening 22, so that the encoder body 3 can be separated from the mounting base 1.

[0024] In the embodiment of the high-precision inductive encoder which is easy to install, the connecting column 62 and the guide pin 52 are arranged on the same diameter of the locking plate 5. The above arrangement makes the overall structure stable and reliable.

Specifically, through the above arrangement, during installation, the motor shaft 92 is passed through the middle of the elastic clamping ring 82, and when the arc-shaped arm 41 descends along the spiral groove 21, the elastic clamping ring 82 follows the encoder body 3 to descend, so that the annular pressure ring 83 compresses the elastic clamping ring 82, and the elastic clamping ring 82 is deformed during the compression process, resulting in a reduction in the inner diameter of the elastic clamping ring 82, thereby being firmly connected to the motor shaft 92.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention.
