Description

Technical Field

[0001] The present invention relates to the field of gear processing, and in particular to a gear processing positioning method and a fixture. Background Art

[0002] Gear machining is a process for manufacturing gears. Its basic principle is to use the geometric shape and size of the gear to manufacture gears through cutting, grinding, forging and other methods. The purpose of gear machining is to meet the requirements of gear precision, strength and life. The positioning fixtures used in existing gear machining have poor clamping stability, and the clamping method and functionality of the fixture are single.

[0003] For example, the Chinese invention patent (application number: CN202110354847.X) discloses a "combination fixture for machining automotive transmission gears." Its description discloses that a combination fixture is a positioning fixture that combines various clamping and positioning structures to meet the processing requirements of a specific workpiece. In the automotive transmission machining process, transmission gears require high-precision machining. Therefore, a combination fixture for automotive transmission gear machining is needed to meet the gear machining, clamping, and positioning requirements. However, existing automotive transmission gear machining processes all use conventional fixtures to clamp gear workpieces. Conventional fixtures are not convenient for self-centering clamping of gears. The center position of the gear workpiece must be repeatedly determined during clamping, which is time-consuming and labor-intensive. Furthermore, conventional fixtures can only clamp gear workpieces on either the outer or inner side, making it difficult to clamp the inner or outer ring of the gear. Furthermore, conventional fixtures are difficult to clamp gear workpieces. The aforementioned patents demonstrate the shortcomings of the prior art.

[0004] Therefore, we made improvements and proposed a gear processing positioning method and fixture. Summary of the Invention

The other end of the torsion spring 306 is connected to the inner wall of the rotating plate 304, and the top of the mounting shaft 305 is fixedly connected to the bottom of the placement table 101.

At this time, the gear is placed on the top of the placement table (101), and the drive motor (313) is started. The drive motor (313) drives the arrayed half gears (301) to rotate through its output end. When the half gears (301) rotate, the rotating plate (304) engaged with the half gears (301) rotates, and the rotating plate (304) drives the extension rod (307) and the clamping sleeve (310) to rotate along the slide groove (103), thereby clamping and fixing the gear. At this time, the servo motor (401) is started, and the triangular rod (402) and the clamping block (403) are driven to rotate by the servo motor (401), and the clamping block (403) is engaged with the rotating plate (304) to fix it. At this time, the half gear (301) is offset along the connecting groove (104) under the rotation of the triangular rod (402). At this time, the half gear (301) is continuously rotated so that the teeth of the half gear (301) contact the transmission plate (205), and then the connecting ring plate (203) and the filter plate (202) are driven to rotate back and forth through the transmission plate (205), thereby filtering the cutting fluid until the gear processing is completed.
