It is understood that the ultrasonic vibration on the ultrasonic rotating shaft is longitudinal ultrasonic vibration, or torsional ultrasonic vibration, or transverse ultrasonic vibration; in another embodiment, the ultrasonic vibration on the ultrasonic rotating shaft can be a composite of any two of longitudinal ultrasonic vibration, torsional ultrasonic vibration and transverse ultrasonic vibration; in still another embodiment, the ultrasonic vibration on the ultrasonic rotating shaft may be a composite of the above three ultrasonic vibrations, which is not limited herein.

Referring to fig. 5, a cutter grinding method according to a second aspect of the present application is further provided, which employs the cutter grinder 100 according to any one of the embodiments of the first aspect, and includes:

s10, the tool is secured to the mounting assembly 22.

Specifically, the tool is detachably mounted on the mounting portion of the mount 222 by a jig.

And S20, adjusting the position of the mounting assembly 22 through the workpiece adjusting seat 21, adjusting the position of the grinding head 32 through the grinder adjusting bracket 31 so that the grinding head 32 corresponds to the first grinding point position of the cutter, and driving the grinding head 32 to rotate so as to grind the first grinding point position.

Specifically, the position of the workpiece in the horizontal plane is roughly adjusted by the first linear sliding table 213 and the second linear sliding table 214, and the position of the tool in the horizontal plane is finely adjusted by the third linear sliding table 215 so that the tool corresponds to the grinding head 32; adjusting the second cross-shaped sliding table 411 to enable the supporting piece 412 on the second cross-shaped sliding table 411 to move to a proper position, so that the camera 42 arranged on the supporting piece 412 is located at the top of the cutter and the grinding head 32, roughly adjusting the height of the camera 42 through the adjusting piece, and precisely adjusting the height of the camera 42 by combining with the fourth straight-line sliding table 413 to enable the camera 42 to keep a proper distance from the cutter; then, adjusting the shape of the shaping piece 47 to make the illuminating piece 46 and the camera 42 be at a proper distance, so as to supplement light for the shooting environment of the camera 42; then, height adjustment of the grinding head 32 is achieved in the vertical direction by adjusting the position of the slide member 312 on the vertical adjustment member 311 to secure a working distance between the grinding head 32 and the tool; secondly, the position of the cutter on the horizontal plane is accurately adjusted through the first cross sliding table 221, and the accurate distance between the cutter and the grinding head 32 is realized by combining the camera 42 and the display 43; the motor and ultrasonic generator are activated to drive the grinding head 32 to grind the first grinding point location of the tool.

S30, driving the mounting member 22 and the tool to rotate horizontally through the workpiece adjusting seat 21 so that the grinding head 32 corresponds to the second grinding point position of the tool, and driving the grinding head 32 to rotate to grind the second grinding point position.

Specifically, by driving the rotary member 2122 in the workpiece adjustment seat 21 to rotate, the second grinding point position of the adjustment tool is ground by the grinding head 32.

In addition, the mounting assembly 22 and the tool are driven to rotate horizontally by the workpiece adjusting seat 21, so that the grinding head 32 corresponds to other grinding points of the tool, and the grinding head 32 is driven to grind the other grinding points until the grinding of the tool is completed. And after the grinding is finished, the motor and the ultrasonic generator are turned off.

According to the tool grinding method, the mounting assembly 22 and the grinding head 32 arranged on the workbench 10 can be used for mounting a tool and grinding the tool, the mounting assembly 22 can be used for realizing position adjustment and horizontal rotation, namely, the mobility of the tool fixed on the mounting assembly 22 is improved, and then the position of the grinding head 32 can be adjusted through the grinding machine adjusting support 31, so that the position relation between the grinding head 32 and the tool can be flexibly adjusted, different positions on the tool can be ground through the grinding head 32, and the machining and the fine grinding of different positions of the tool can be realized. Secondly, because bistrique 32 locates on the supersound rotation axis, can further improve the operating mass and the work efficiency of bistrique 32, and conveniently get rid of the abrasive dust. In addition, need not artifical manual regulation cutter position among the grinding process, degree of automation is high, has promoted the stability of cutter work piece quality among the batch machining process, has effectively solved among the prior art and has been difficult to satisfy the processing and the accurate grinding of the inside and outside R angle of cutter, technical problem that degree of automation is low simultaneously.

The above-mentioned embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the spirit and scope of the embodiments of the present application and are intended to be included within the scope of the present application.
