[0060] Embodiment three

[0061] On the basis of the embodiment 1, in order to facilitate the pulling of the encoder joint 3 from the encoder interface 2, a pushing structure for pushing the encoder joint 3 away from the encoder interface 2 is arranged on the positioning structure.

[0062] The pushing structure includes a limiting seat 6 arranged above the integrated servo motor 1, a limiting guide rod 601 slidingly installed inside the connecting slide rod 401, the limiting guide rod 601 being arranged on one side of the limiting seat 6, and a pushing spring 602 arranged between the limiting seat 6 and the connecting slide rod 401, the pushing spring 602 being slidingly sleeved on the limiting guide rod 601. The U-shaped limiting rod 5 is pulled upward to be out of the blockage of one side of the connecting slide rod 401, and at this time, the pushing spring 602 in the compressed state pushes the connecting slide rod 401 to move to reset, thereby pulling the encoder joint 3 out of the encoder interface 2.

[0063] The pushing structure further includes a guide sliding hole 603 opened inside the connecting slide rod 401 to guide the moving direction of the connecting slide rod 401, and the limiting guide rod 601 is slidingly installed in the guide sliding hole 603. When the connecting slide rod 401 moves, it can slide along the limiting guide rod 601 through the guide sliding hole 603, thereby limiting the movement of the connecting slide rod 401 in the horizontal direction.

[0064] Working principle

[0065] When the encoder joint 3 needs to be connected to the encoder interface 2, refer to the state of Figure Two , in which the push spring 602 is in the expanded state, and the auxiliary spring 508 is in the contracted energy storage state. When installing, the encoder joint 3 can be first placed in the clamping groove on the limiting sleeve shell one 4, and the clamping groove on the limiting sleeve shell one 4 is in a corresponding state with the encoder interface 2, so that the encoder joint 3 placed in the limiting sleeve shell one 4 can be exactly aligned with the encoder interface 2, and the encoder joint 3 is quickly positioned. At this time, the connecting slide rod 401 can be pulled, and the connecting slide rod 401 will slide on the fixed guide rod 402 and move the limiting sleeve shell one 4, so that the limiting sleeve shell one 4 inserts the encoder joint 3 into the encoder interface 2, thereby quickly completing the connection of the encoder joint 3 and the encoder interface 2. During the continuous movement of the connecting slide rod 401, it will be separated from the contact with the U-shaped limiting rod 5, and the T-shaped clamping block 509 will be matched with the T-shaped clamping groove 510. At this time, the auxiliary spring 508 in the contracted energy storage state will release and push the linkage rod 507 to move downward. When the linkage rod 507 moves, it will drive the movable guide rod 505 to slide in the fixed seat 504, thereby limiting the linkage rod 507 to slide only in the vertical direction. The movable guide rod 505 can be prevented from sliding out of the fixed seat 504 by setting the stop block 506. The continuously moving linkage rod 507 can drive the U-shaped limiting rod 5 to move downward, so that the U-shaped limiting rod 5 covers the encoder joint 3 with the limiting sleeve shell two 501, and at the same time, the U-shaped limiting rod 5 drives the sealing clamping strip 503 to insert into the positioning clamping groove 502 on the limiting sleeve shell one 4, thereby improving the sealing between the limiting sleeve shell two 501 and the limiting sleeve shell one 4. The U-shaped limiting rod 5 can drive the T-shaped clamping block 509 to slide into the T-shaped clamping groove 510, and at the same time, the U-shaped limiting rod 5 will block one side of the connecting slide rod 401, thereby limiting the position of the connecting slide rod 401, and preventing the limiting sleeve shell two 501 from deviating from above the limiting sleeve shell one 4. Under the wrapping and limiting of the limiting sleeve shell two 501 and the limiting sleeve shell one 4, the connection of the encoder joint 3 can be finally reinforced, thereby preventing the encoder joint 3 from being loosened from the encoder interface 2. The state after connection can be referred to Figure One .

[0066] Referring to the state of Figure Two , when the connecting slide rod 401 drives the limiting sleeve shell one 4 and the encoder joint 3 to move and connect, the moving connecting slide rod 401 will slide on the limiting guide rod 601, thereby limiting the connecting slide rod 401 to move only in the horizontal direction. The connecting slide rod 401 can be prevented from loosening from the limiting guide rod 601 by setting the limiting seat 6, and the continuously moving connecting slide rod 401 can extrude the push spring 602 by cooperating with the limiting seat 6, so that the push spring 602 is compressed and stored energy. Referring to Figure OneWhen the encoder joint 3 needs to be pulled off from the encoder interface 2, the U-shaped limiting rod 5 can be pulled upward to be separated from the blocking of one side of the connecting slide rod 401, and the limiting sleeve shell 501 is separated from the encoder joint 3, so that the position limitation of the connecting slide rod 401 is released, the push spring 602 in the compressed state pushes the connecting slide rod 401 to move to reset, and the connecting slide rod 401 in the reset state drives the encoder joint 3 to be pulled out of the encoder interface 2, so that the encoder joint 3 is quickly disassembled.

Therefore, if these modifications and variations of the present application belong to the scope of the claims of the present application and the equivalent technologies, the present application also intends to include these modifications and variations.
