Description

A gear shaft keyway machining milling tool

Technical Field

The utility model relates to the technical field of gear shaft keyway production and processing, in particular to a gear shaft keyway processing milling tool.

Background Art

Gears are a widely used component in mechanical transmission, mainly used to change the speed, transmit power or change the direction of movement. The shape and size of the gear are determined by the transmission function required, including straight teeth, helical teeth and herringbone teeth. The manufacture of gears requires precise processes and materials to ensure their wear resistance and reliability. Gears are widely used in various machinery and equipment, such as automobiles, bicycles, clocks, pumps and turbines. The gear shaft of the gear is usually machined with keyways at both ends. The keyways on the gear shaft are used to connect the gear and the shaft. The gear can be fixed on the shaft to ensure that the gear can work normally and transmit torque. Common keyways include rectangular keyways, trapezoidal keyways, semicircular keyways and diamond keyways. Trapezoidal keyways are more commonly used because they have a larger bite force. When processing the keyway of the gear shaft, a milling tool is required.

Common gear shaft keyway processing milling tooling usually consists of a base, a positioning device, a fixture, a milling device, and a guide device. When the gear shaft is keyway processed, the gear shaft is placed between the first clamping member and the second clamping member, and the second clamping member is moved to the keyway position to process the keyway. This is a common milling tooling mechanism and usage. In the traditional gear shaft keyway processing milling tooling, the gear shaft is mounted on a fixed V-shaped tooling and the gear shaft is clamped with a sliding V-shaped plate. Since the sliding V-shaped plate is pushed by only one locking screw, it is easy to shake left and right, resulting in unstable slot size. In some gear shaft keyway processing milling tooling, the gear shaft is placed in the positioning slot, the lower end is fixed by the groove on the lower positioning plate, the upper end is clamped by the sliding V-shaped plate, the top screw limits the sliding V-shaped plate to the left and right, and the locking screw is in contact with the sliding V-shaped plate. However, in this method, the locking screw and the top screw are rotationally fixed through the external thread on the surface, but vibration will occur when the keyway is processed on the gear shaft, and the locking screw and the top screw will loosen, making the sliding V-shaped plate lose stability in fixing the gear shaft, resulting in the failure of the gear shaft shaking processing. Therefore, a gear shaft keyway processing milling tool is proposed.
