[0002] Metalworking grinding machine tools are used to process metal or non-metal workpieces that require special grinding wheel shapes. After grinding, the workpiece achieves the corresponding shape and structure. Existing grinding wheel correction mechanisms can complete the correction of simple shapes, but cannot complete the correction of complex shapes or multi-angle planes, as well as the correction of non-parallel planes with high flatness requirements. Utility Model Content

[0003] The purpose of this invention is to overcome the problems existing in the prior art and provide a multi-angle reciprocating grinding wheel dressing mechanism. When the grinding wheel is worn as the main wear, it can correct the plane that is not parallel to the machine tool's motion axis, and can achieve more precise angles of plane correction. If the motion control and trajectory control of the servo motor are achieved through the machine tool's host computer, the corrected shapes can be further increased, which can meet more complex processing requirements.

[0004] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] Furthermore, a reciprocating motor is provided on the frosted mounting plate, and the output end of the reciprocating motor is connected to the turntable output mounting plate through a connecting rod, so that the frosted mounting plate can perform reciprocating linear motion on the turntable output mounting plate under its drive.

[0007] Furthermore, the frosted mounting plate is slidably connected to the turntable output mounting plate via a guide rail slider, and under the drive of the reciprocating motor, the frosted mounting plate reciprocates linearly along the direction of the guide rail slider.

[0008] Furthermore, the output end of the reciprocating motor is connected to a connecting rod via a reduction mechanism.

[0009] Furthermore, the sanding mounting plate is vertically provided with a sanding bracket, on which a sanding roller motor and a sanding roller spindle are respectively mounted. The sanding roller motor is connected to and drives the sanding roller spindle via a belt.

[0010] The beneficial effects of this utility model are:

[0011] When the grinding wheel is worn as the main wear material, this utility model mechanism can correct planes that are not parallel to the machine tool's motion axis, achieving more precise plane corrections of shapes and angles. This mechanism can replace the original grinding pen or grinding roller and can be installed in the machine tool or grinding wheel dressing device.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 3 As shown, a multi-angle reciprocating grinding wheel dressing mechanism includes a turntable 1 and a turntable motor 6 connected to and driving the turntable 1 to rotate. 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 sanding mounting plate 13 is slidably provided on the turntable output mounting plate 2. A sanding roller motor 5 and a sanding roller spindle 4 connected to and driven by the sanding roller motor 5 are provided on the sanding roller spindle 4. A grinding wheel dressing roller 12 is provided on the sanding roller spindle 4 for dressing the grinding wheel 11 to be dressed.

[0019] A reciprocating motor 9 is installed on the frosted mounting plate 13. The output end of the reciprocating motor 9 is connected to the turntable output mounting plate 2 via a connecting rod 10. Under its drive, the frosted mounting plate 13 performs reciprocating linear motion on the turntable output mounting plate 2. In a specific implementation, the connecting rod 10 can be a lead screw connecting rod. The reciprocating motor 9 drives the lead screw connecting rod to rotate. A lead screw nut is connected to the lead screw connecting rod and is fixed to the turntable output mounting plate 2. The frosted mounting plate 13 is driven by the lead screw nut to perform linear reciprocating motion relative to the turntable output mounting plate 2. In another embodiment, the connecting rod 10 can be a double-threaded connecting rod, with both ends of the double-threaded connecting rod rotatably connected to the spherical bearings 3. One end of the spherical bearing 3 is rotatably connected to the turntable output mounting plate 2, and the other end of the spherical bearing 3 is eccentrically rotatably connected to the eccentric disk driven by the reciprocating motor 9. If a reduction mechanism 8 is provided, the reduction mechanism 8 is set between the reciprocating motor 9 and the eccentric disk, and works with the guide rail slider 7 to convert the rotational motion into linear reciprocating motion. The eccentric reciprocating drive structure drives the frosted mounting plate 13 to reciprocate relative to the turntable output mounting plate 2.

[0020] The frosted mounting plate 13 is slidably connected to the turntable output mounting plate 2 via the guide rail slider 7. Driven by the reciprocating motor 9, the frosted mounting plate 13 reciprocates linearly along the direction of the guide rail slider 7.

[0021] The output end of the reciprocating motor 9 is connected to the connecting rod 10 through the reduction mechanism 8.

[0022] The sanding mounting plate 13 is vertically provided with a sanding bracket 14. The sanding bracket 14 is respectively equipped with a sanding roller motor 5 and a sanding roller spindle 4. The sanding roller motor 5 is connected to and drives the sanding roller spindle 4 through a belt.

[0023] Working principle of this utility model

[0024] At work, such as Figure 4 As shown, the turntable motor 6 controls the placement angle of the dressing roller 12 and the grinding wheel 11 to be dressed via the high-precision turntable 1. The reciprocating motor 9 provides power for the dressing roller 12 to perform linear reciprocating motion under the constraint of the guide rail slider 7. The dressing roller motor 5 provides power for the rotation of the dressing roller 12, completing the linear reciprocating motion of the dressing roller 12 relative to the grinding wheel 11 at a set angle. By controlling the relative position of the dressing roller 12 and the grinding wheel 11 to be dressed in this way, planar grinding and dressing of the grinding wheel 11 at a set angle is achieved. During the dressing action, when the dressing roller 12 is the main consumable material, it can ensure uniform grinding and correction at the contact surface between the two, uniform consumption, and ensure the planarity of the surface of the grinding wheel 11 to be dressed.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
