Description
TECHNICAL FIELD
[0001] The utility model relates to the field of grinding equipment, and particularly to a grinding head driving structure. BACKGROUND
[0002] The shape and profile of modern cutters are increasingly complex, and many cutters have unique cutting edge angles and curves. The existing grinding head cannot adjust the angle in real time. When different angle cutters or different angle parts on the same cutter need to be ground, the operator may need to disassemble and re-clamp the cutter multiple times to change the relative angle between the cutter and the grinding head, thereby reducing the grinding efficiency. In addition, since the grinding head cannot adjust the angle in real time, it is difficult to accurately grind along these complex profiles, resulting in deviations between the shape of the ground cutter and the design requirements, affecting the cutting performance and machining quality of the cutter. Finally, if the grinding head cannot adjust the angle in real time, even a small angle deviation during the grinding process will gradually accumulate if it is not adjusted in time. This will cause the cutting edge angle of the cutter to gradually deviate from the ideal value, ultimately leading to inaccurate cutting angle of the cutter and reducing the cutting efficiency and service life of the cutter.

[0028] The preferred embodiments of the utility model will be further described with reference to the drawings, and the preferred embodiments of the utility model will be further described with reference to the drawings Figure 1 And Figure 2 As shown in the figure, a grinding head driving structure, including drive module 100 and movable plate 200, drive module 100 is arranged on the end surface of movable plate 200, drive module 100 includes first actuator 110 and driving wheel 120, first actuator 110 is used to drive driving wheel 120 to rotate, driving wheel 120 and movable plate 200 are connected through gear structure engagement, driving wheel 120 is used to drive movable plate 200 to reciprocate along its end surface, and grinding module 300 is arranged on the other end surface of movable plate 200, grinding module 300 includes second actuator 310 and grinding head 320, second actuator 310 is used to drive grinding head 320 to rotate.
[0029] In the working state of the embodiment, the tool head is first fixed at a preset position, the grinding head 320 is aligned with the blade part, and then the second actuating mechanism 310 is started to drive the grinding head 320 to rotate to grind the blade part. When it is necessary to adjust the grinding angle, the second actuating mechanism 310 is started to drive the driving wheel 120 to rotate. Since the driving wheel 120 and the movable plate 200 are engaged and connected, when the driving wheel 120 rotates, the movable plate 200 will move reciprocatingly along the end surface of the movable plate 200, so that the grinding head 320 can be deflected at a preset angle, thereby achieving the effect of adjusting the grinding angle.
[0030] The application drives the movable plate 200 to move reciprocatingly and deflect along the end surface thereof by the driving module 100, so that the grinding head 320 can be deflected at a preset angle, thereby the grinding angle can be adjusted in real time in the direction around the blade during grinding of the blade, and different shapes of the blade can be ground according to different customer requirements.

When the driving wheel 120 rotates, the movable plate 200 moves reciprocatingly and deflects in an arc shape with the center of the arc gear strip 210 as the axis. Therefore, in the working state of the embodiment, when the grinding head 320 grinds the blade part, the second actuating mechanism 310 is started to drive the driving wheel 120 to rotate, and the grinding head 320 can move reciprocatingly and deflect in an arc shape within a preset angle range (for example, within 20 degrees), forming a movement track similar to a pendulum, so that the blade part can be ground to have an arc.

[0034] Further based on the above embodiment, as shown in Figure 5 As shown, the second actuating mechanism 310 comprises a supporting seat 311 and a second rotary motor 312, the supporting seat 311 is connected to the end face of the movable plate 200, the second rotary motor 312 is fixed to the side of the supporting seat 311 away from the movable plate 200, and the grinding head 320 is connected to the output end of the second rotary motor 312, when the blade needs to be continuously ground, the grinding rotation can be driven by starting the second rotary motor 312.
[0035] In some embodiments, as shown in Figure 5 The moving device 330 is arranged between the supporting seat 311 and the movable plate 200, and is used to drive the supporting seat 311 and the second rotary motor 312 to move linearly along the end face of the movable plate 200, so that when the preset position of the blade head is far away from the movable plate 200, the moving device 330 can drive the supporting seat 311 and the second rotary motor 312 to move towards the direction of the blade head as a whole, so that the grinding head 320 can contact the blade, or in the process of grinding, when the special-shaped blade is ground, the distance between the grinding head 320 and the blade can also be adjusted by the moving device 330.
