Description

Technical Field

[0001] This utility model belongs to the field of electronic handwheel technology, specifically relating to an electronic handwheel moving grating positioning structure. Background Technology

[0002] As a key input device for human-machine interaction, the electronic handwheel's core function is to convert the operator's precise mechanical rotational movements into high-resolution, high-precision digital pulse signals. This signal conversion relies on a grating rotary encoder, whose performance directly determines the electronic handwheel's resolution, accuracy, anti-interference capability, and long-term stability. In the core structure of the grating encoder, the stationary grating (usually fixed to the handwheel's base) and the moving grating (rigidly mounted on a rotating gear disk) form a precise optical measurement pair; the initial relative position of the windows of the stationary and moving gratings determines the encoder's output accuracy and reliability.

[0003] In the current electronic handwheel manufacturing process, after the stationary and moving gratings are installed according to the production process, manual inspection and adjustment of the window alignment of the moving and stationary gratings using a microscope are still required to ensure the accuracy of the relative position of the moving and stationary grating windows. This process is time-consuming and labor-intensive, resulting in high labor intensity for workers and low overall production efficiency. Summary of the Invention

[0004] The purpose of this utility model is to provide an electronic handwheel moving grating positioning structure. After the moving grating is installed through this positioning structure, the window of the moving grating is matched with the window of the static grating, thus meeting the accuracy requirements.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: an electronic handwheel moving grating positioning structure, characterized in that: it includes a plurality of moving grating positioning posts arranged on a rotating gear disk, and the moving grating is provided with positioning holes corresponding to the moving grating positioning posts. After the moving grating is installed by adapting to the moving grating positioning posts through the positioning holes, the window of the moving grating is adapted to the window position of the static grating.

[0006] Furthermore, the moving grating positioning post is provided with 5 posts, which are evenly distributed on the circumference with the moving grating.

[0007] Furthermore, the rotating gear disk and the moving grating positioning post are integrally formed.

[0008] Furthermore, the rotating gear disk and the moving grating positioning post are injection molded as a single unit.

[0009] The beneficial effects of this utility model are as follows: The above structure enables precise positioning and installation. After the moving grating is installed by fitting it with the positioning post through the positioning hole, the window of the moving grating matches the window position of the static grating, meeting the accuracy requirements. The installation process eliminates the need for manual inspection and adjustment, effectively reducing the labor intensity of workers and increasing production efficiency.

Detailed Implementation

[0014] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] like Figure 1 , 2 As shown, an electronic handwheel movable grating positioning structure includes multiple movable grating positioning posts 2 disposed on a rotating gear disk 1. Positioning holes 4 are provided on the movable grating 3, the positions and number of which correspond to the movable grating positioning posts 2. During production and assembly, the stationary grating 5 is positioned and installed on the main body base 6 of the handwheel, and the rotating gear disk 1 is mounted on the main body base 6 via a main shaft 7. The movable grating 3 is aligned and installed through the positioning holes 4 with the movable grating positioning posts 2 on the rotating gear disk 1. After installation, the window 8 of the movable grating matches the window 9 of the stationary grating; that is, the window 8 of the movable grating and the window 9 of the stationary grating form a fixed angle and remain concentric, meeting the accuracy requirements of their relative positions.

[0016] Preferably, there are five moving grating positioning posts 2, evenly distributed on a circle with the same center as the moving grating 3. This design, by setting five grating positioning posts, eliminates the need for mistaken installation for both 25-window and 100-window moving gratings, greatly improving production efficiency.

[0017] Preferably, the rotating gear disk 1 and the moving grating positioning post 2 are integrally formed; if injection molding is used to directly integrally form the product, the injection molded product has high dimensional accuracy and stability, while also having high production efficiency and low cost.

[0018] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
