The dual-encoder synchronous motion device provided in this embodiment mainly includes a fixed support 3, an encoder support (including a middle plate 8 and two side plates 4), an encoding wheel 1, a guide shaft 5, and a spring (not shown in the figure). The encoder support is connected with the fixed support 3 through a guide shaft 5, a relatively sliding structure is formed between the connected encoder support and the fixed support 3, namely, the encoder support and the fixed support 3 can generate relative displacement along the axial direction of the guide shaft 5, a spring is sleeved on the guide shaft 5 and is in a compressed state and used for providing pretightening force.
In a specific implementation manner provided in this embodiment, the guide shaft 5 is slidably matched with the fixed support 3, and the guide shaft 5 is fixedly connected with the encoder support, so that the encoder support drives the guide shaft 5 to move when being stressed, and the encoder support and the fixed support 3 can slide relatively. In another embodiment provided in this embodiment, the guide shaft 5 may be slidably engaged with the encoder support, and the guide shaft 5 is fixedly connected to the fixed support 3, so that the encoder support may slide along the guide shaft 5 when being stressed, thereby realizing the relative sliding between the encoder support and the fixed support 3.
In the illustration of the utility model, a display form of sliding fit of the guide shaft 5 and the fixed support 3 is adopted, as shown in fig. 1, the fixed support 3 is of an L-shaped structure as a whole, two fixed mounting holes are arranged on a bottom plate of the fixed support, two through holes are arranged on a vertical plate, a linear bearing 10 is arranged in the through holes, the guide shaft 5 passes through the linear bearing 10, a limiting baffle 6 is arranged at one end extending out of the fixed support 3, the limiting baffle 6 is used for preventing the guide shaft 5 from exceeding the range during sliding, and the linear bearing 10 is used for obtaining stable linear motion with high sensitivity and high precision.
In this embodiment, the encoder support is preferably constructed as shown. The device comprises a middle plate 8 and two side plates 4 fixedly connected with the middle plate 8, wherein the middle plate 8 is fixedly connected with two guide shafts 5, and encoder fixing plates 9 are respectively arranged on the outer sides of the side plates 4. The two encoders are fixed to the corresponding encoder fixing plates 9, respectively.
