Description

Technical Field

[0001] This utility model relates to the field of gear processing clamping technology, specifically a clamping mechanism for a gear processing and grinding device. Background Technology

[0002] A gear is a mechanical component with teeth on its rim that continuously meshes to transmit motion and power. It is a wheel-shaped mechanical part that transmits torque through the meshing of its teeth. Gears can be classified structurally into teeth, tooth spacers, end faces, normal faces, addendum circles, dedendum circles, base circles, and pitch circles. Gears can be classified in several ways, including by tooth profile: Spur gears: The tooth line is straight in the axial direction. Helical gears: The tooth line is inclined in the axial direction, which can improve the smoothness of transmission and load-bearing capacity. Double helical gears: Composed of two opposing helical gears side by side, which can eliminate lateral forces on the shaft. Spiral gears: Cylindrical gears with a cylindrical helix tooth line, used to transmit motion between shafts that are neither intersecting nor parallel.

[0003] Currently, Chinese patent publication number CN217096014U discloses a clamping mechanism for a gear processing and grinding device. This mechanism offers a time-saving and labor-saving clamping and fixing process, high stability, and high practicality. It is suitable for clamping and fixing gears of varying thicknesses. The mechanism includes a support platform, a fixing plate below the support platform, a motor mounted on the fixing plate, and multiple transmission sleeves rotatably connected to the fixing plate. The motor's output shaft is fixedly connected to one of the transmission sleeves. Conveyor belts are fitted onto the transmission sleeves, and screws are fixedly connected to each of the transmission sleeves. Each screw is rotatably connected to the bottom end of the support platform. Adjusting plates are threaded onto the screws, and adjusting cylinders are mounted on the adjusting plates. Electric push rods are mounted on the adjusting cylinders, and adjusting rods are mounted on the output shafts of the electric push rods. A limit plate is mounted on the top of the adjusting rod, and a limit bottom plate is slidably connected to the adjusting rod. A fixing ring is mounted on the adjusting cylinder.

[0004] Compared to this technology: This technology only supports the inside of the gear and cannot clamp the gear from top to bottom. The main function of the clamping mechanism is to ensure that the gear maintains a stable position and posture during the processing. If the clamping mechanism cannot clamp the gear from top to bottom, the gear may move or deform slightly during the processing due to the influence of cutting force or grinding force. This movement or deformation will cause deviations in the geometric dimensions of the gear, thus affecting the processing accuracy of the gear. Utility Model Content
