The output end of the reciprocating motor is connected to the turntable output mounting plate through a connecting rod, and under its drive, the grinding mounting plate makes a reciprocating linear motion on the turntable output mounting plate.

[0006] Further, the grinding mounting plate is slidably connected to the turntable output mounting plate through a guide rail and slider, and under the drive of the reciprocating motor, the grinding mounting plate makes a reciprocating linear motion along the direction of the guide rail and slider.

[0012] The present invention will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0013] As Figures 1 to 3 shown, a multi-angle reciprocating grinding wheel dressing mechanism includes a turntable 1 and a turntable motor 6 that is connected to and drives the rotation of the turntable 1. A turntable output mounting plate 2 is connected to the rotating end of the turntable 1. The turntable motor 6 can be controlled by a corresponding controller to drive the high-precision turntable 1 to rotate the turntable output mounting plate 2 to a set angle. A grinding installation plate 13 is slidably arranged on the turntable output mounting plate 2. A grinding wheel roller motor 5 and a grinding wheel roller main shaft 4 that is connected to and driven by the grinding wheel roller motor 5 are arranged on the grinding installation plate 13. A grinding wheel dressing roller 12 is arranged on the grinding wheel roller main shaft 4 for dressing the grinding wheel 11 to be dressed.

[0014] A reciprocating motor 9 is provided on the frosted mounting plate 13. The output end of the reciprocating motor 9 is connected to the turntable output mounting plate 2 through a connecting rod 10. Driven by it, the frosted mounting plate 13 makes a reciprocating linear motion on the turntable output mounting plate 2. In specific implementation, the connecting rod 10 can adopt a lead screw connecting rod. The reciprocating motor 9 drives the lead screw connecting rod to rotate. A lead screw nut is connected in cooperation with the lead screw connecting rod, and the lead screw nut is fixedly connected to the turntable output mounting plate 2. The frosted mounting plate 13 is driven to make a linear reciprocating motion relative to the turntable output mounting plate 2 in the driving mode of the lead screw nut. In another implementation manner, the connecting rod 10 can adopt a double-threaded connecting rod. Both ends of the double-threaded connecting rod are rotatably connected to a spherical plain bearing 3. One of the spherical plain bearings 3 is rotatably connected to the turntable output mounting plate 2, and the other spherical plain bearing 3 is eccentrically rotatably connected to an eccentric disc driven by the reciprocating motor 9. If a speed reduction mechanism 8 is provided, the speed reduction mechanism 8 is arranged between the reciprocating motor 9 and the eccentric disc. In the way of converting the rotary motion into a linear reciprocating motion by cooperating with a guide rail slider 7, the frosted mounting plate 13 is driven to make a reciprocating motion relative to the turntable output mounting plate 2 by an eccentric reciprocating driving structure.

[0015] The frosted mounting plate 13 is slidably connected to the turntable output mounting plate 2 through a guide rail slider 7. Driven by the reciprocating motor 9, the frosted mounting plate 13 makes a reciprocating linear motion along the direction of the guide rail slider 7.

[0016] The output end of the reciprocating motor 9 is connected to the connecting rod 10 through a speed reduction mechanism 8.

[0017] A frosted support 14 is vertically provided on the frosted mounting plate 13. A grinding wheel dressing roller motor 5 and a grinding wheel dressing roller main shaft 4 are respectively installed on the frosted support 14. The grinding wheel dressing roller motor 5 is connected by a belt and drives the grinding wheel dressing roller main shaft 4.

[0018] Working principle of the present invention During working, as Figure 4 shown, the turntable motor 6 controls the placement angle of the grinding wheel dressing roller 12 and the grinding wheel to be dressed 11 through the high-precision turntable 1. The reciprocating motor 9 provides the power for the grinding wheel dressing roller 12 to make a linear reciprocating motion under the constraint of the guide rail slider 7. The grinding wheel dressing roller motor 5 provides the power for the grinding wheel dressing roller 12 to rotate, completing the linear reciprocating motion of the grinding wheel dressing roller 12 relative to the grinding wheel to be dressed 11 at a set angle. With this control of the relative position between the grinding wheel dressing roller 12 and the grinding wheel to be dressed 11, the plane grinding and dressing of the grinding wheel to be dressed 11 at a set angle is realized. During the grinding wheel dressing operation, when the grinding wheel dressing roller 12 is the main consumable material, uniform grinding and correction can be ensured at the contact surface between the two, and uniform consumption can be guaranteed, ensuring the flatness of the surface of the grinding wheel to be dressed 11 to be dressed.

[0019] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
