[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0042] 1 , the grinding machine with ultrasonic processing of the present invention comprises: a machine tool 1, a Z-axis transfer assembly 2, an X-axis transfer assembly 3, a headstock assembly 4, an ultrasonic generating device 5 and a grinding assembly;

[0043] The machine tool 1 is a T-shaped structure, and the Z-axis transfer assembly 2 and the X-axis transfer assembly 3 are both arranged on the machine tool 1.

The Z-axis direction and the X-axis direction are perpendicular, and the Z-axis transfer assembly 2 and the X-axis transfer assembly 3 are perpendicular.

[0044] The headstock assembly 4 and the ultrasonic generating device 5 are arranged on the Z-axis transfer assembly 2. The headstock assembly 4 and the ultrasonic generating device 5 are driven by the Z-axis transfer assembly 2 and move along the Z-axis direction. The headstock assembly 4 is used to clamp the product to be processed. The ultrasonic generating device 5 is arranged on one side thereof corresponding to the headstock assembly 4. The execution end of the ultrasonic generating device 5 acts on the workpiece to be processed. The ultrasonic generating device 5 can emit ultrasonic waves to act on the workpiece to be processed;

[0045] The grinding component is arranged on the X-axis transfer component 3, and the corresponding ultrasonic generating device 5 is arranged on the other side of the head frame component 4. In this embodiment, the grinding component is provided to include: an internal cylindrical grinding device 6 and a thread grinding device 7. The X-axis transfer component 3 drives the internal cylindrical grinding device 6 and the thread grinding device 7 to move. The execution ends of the internal cylindrical grinding device 6 and the thread grinding device 7 can act on the workpiece to be processed respectively, thereby realizing rapid switching actions for different grinding requirements, and can perform various types of grinding operations. In other embodiments, different types of grinding components can be further added according to actual usage requirements, such as: external cylindrical grinding devices, and different configuration combinations of grinding components can also be set. No further limitation is made here. As long as the grinding component is set on the X-axis transfer component 3 and the X-axis transfer component 3 drives the grinding component to move back and forth, it can realize grinding processing of different positions of the product to be processed and different types of grinding processing.

[0046] During actual processing, the workpiece to be processed is clamped on the headstock assembly 4, and the ultrasonic generator 5 is applied to the workpiece. The front end of the ultrasonic generator 5 abuts against the workpiece, which can clamp and limit the workpiece. After the workpiece is clamped and fixed, the Z-axis transfer assembly 2 drives the headstock assembly 4 to move in the direction of the X-axis transfer assembly 3. At the same time, the X-axis transfer assembly 3 drives the grinding assembly to move in the X-axis direction, so that the grinding assembly acts on the initial grinding position of the workpiece. After all are moved into place, the grinding assembly and the ultrasonic generator 5 are turned on, and the Z-axis transfer assembly 2 drives the headstock assembly 4 to feed in the Z-axis direction, and the ultrasonic generator 5 assists the grinding assembly to complete the grinding action.

[0047] In summary, this embodiment provides a grinder with ultrasonic processing and the working action of the grinder. Compared with the grinder structure of the prior art, an ultrasonic generating device 5 is added, and the ultrasonic generating device 5 and the grinding assembly are respectively arranged on both sides of the workpiece to be processed, so that the movements of the two components do not interfere with each other; on the one hand, the ultrasonic generating device 5 is arranged to serve as a positioning mechanism for workpiece installation, and the workpiece can be clamped and limited by the front end of the ultrasonic generating device 5 to ensure the clamping accuracy of the workpiece; on the other hand, the execution end of the ultrasonic generating device 5 is arranged to act on the workpiece to be processed, and the ultrasonic generating device 5 is used to act on the workpiece to be processed when the grinding assembly grinds the workpiece to be processed, thereby assisting the grinding assembly in grinding processing, which can not only improve the processing efficiency, but also effectively reduce the grinding force generated during grinding, and obtain better surface roughness.

In this embodiment, the clamping mechanism 42 is arranged to adopt a hydraulic clamping method, which effectively ensures the uniformity and stability of the workpiece clamping force and the clamping and grinding quality of the workpiece. In other embodiments, other different clamping forms can also be provided, as long as the workpiece can be clamped and fixed; the first turntable 41 is arranged on the X-axis transfer assembly 3, and the clamping mechanism 42 is used to clamp the product to be processed. A turntable 41 drives the clamping mechanism 42 to rotate. When grinding a longer workpiece, the connecting rod in the grinding assembly needs to be made very long, but the diameter of the connecting rod is very small, which will cause the rigidity of the connecting rod to become very fragile, and the connecting rod is easy to bend or break. By using the head frame assembly 4 of the present application, the first turntable 41 under the clamping mechanism 42 can be used to drive the clamping mechanism 42 to rotate 180°, thereby realizing two-sided processing.

Therefore, in this embodiment, an ultrasonic generating device slide is also provided on the Z-axis transfer assembly 2, and the ultrasonic generating device 5 is provided on the ultrasonic generating device slide 51. The ultrasonic generating device 5 is configured to be able to move relative to the head frame assembly 4. When loading, the ultrasonic generating device 5 is configured to slide on the ultrasonic generating device slide 51 in the direction away from the head frame assembly 4 to avoid the loading action. After loading is completed, the ultrasonic generating device 5 is configured to slide on the ultrasonic generating device slide 51 in the direction close to the head frame assembly 4, so that the execution end of the ultrasonic generating device 5 can act on the workpiece.

The thread grinding body 74 can rotate under the drive of the third turntable 73. When grinding the thread raceway of the workpiece, the thread raceway will have a specific thread lead angle. During grinding, the thread grinding body 74 will be driven by the third turntable 73 to rotate to the angle set in the system, and at the same time cooperate with the Y-axis transfer component 72 to move up and down in the Y-axis direction, so that the center height of the thread grinding body 74 remains unchanged to meet the grinding process requirements.

[0053] Specifically, the thread grinding body 74 includes a thread grinding head and a thread grinding drive source. The thread grinding drive source drives the thread grinding head to rotate to complete the grinding action.

[0054] As shown in Figure 6, the thread grinding device 7 also includes a measuring instrument arranged on the mounting frame 71. The measuring instrument is set in the direction of the workpiece to be processed. The relative position of the workpiece and the thread grinding body 74 can be determined by the measuring instrument, so that the feed position can be determined during initial processing.
