Claims

1. A groove milling device using a groove roller, comprising a motor, a transmission system, a cutting component, a workpiece clamping device, and a groove roller; wherein the motor drives the transmission system, the transmission system controls the movement of the cutting component, and the workpiece clamping device clamps the groove roller; characterized in that: It also includes a milling cutter shaft, which adopts a high-speed rotary bearing structure with zero backlash. A preload adjustment device is provided between the inner and outer rings of the bearing to ensure the stability and accuracy of the milling cutter shaft when rotating at high speed. The milling cutter shaft is equipped with multiple replaceable milling cutters to adapt to the needs of groove milling of different sizes and shapes.

2. The groove milling device according to claim 1, characterized in that: The motor is a variable frequency motor, and the transmission system includes a tensionable belt drive. The variable frequency motor is connected to the belt drive through a reducer to drive the milling cutter shaft to rotate.

3. The groove milling device according to claim 2, characterized in that: The device also includes a positioning device and a clamping device to ensure the stability and accuracy of the grooved roller during the milling process. The positioning device adopts a combination design of precision guide rail and positioning block, and the clamping device adopts pneumatic or hydraulic clamping to ensure that the grooved roller does not shift or shake during the milling process.

4. The groove milling device according to claim 3, characterized in that: It also includes an adjustment mechanism for adjusting the relative position between the milling cutter shaft and the groove roller, including a radial adjustment mechanism and an axial adjustment mechanism; the radial adjustment mechanism adjusts the groove width by adjusting the position of the milling cutter shaft in the horizontal direction; the axial adjustment mechanism adjusts the groove depth by adjusting the position of the milling cutter shaft in the vertical direction.

5. The groove milling device according to claim 1, characterized in that: The preload adjustment device includes a worm and a drive device. The worm is disposed inside the bearing housing and works in conjunction with the worm wheel. The drive device is used to drive the worm shaft to rotate, thereby driving the worm wheel and the preload adjustment spacer to move, so as to adjust the bearing preload.
