Problems solved by technology
[0006] The ultrasonic polishing process can provide sufficient grinding pressure, but it is rarely used in the traditional polishing field, because the traditional polishing process mostly uses grinding wheels for polishing. If the ultrasonic generator is combined with traditional polishing equipment, the grinding wheel and the workpiece will produce a large amount of friction during polishing. Rigid impact, resulting in poor workpiece surface quality

Embodiment Construction
[0022] The specific embodiment of the present invention is further described below in conjunction with accompanying drawing:
[0023] Such as Figure 1-Figure 2 , the device for removing burrs on the edge of holes by de-rotating ultrasonic magnetic combination, including a vertical milling machine 1, an ultrasonic generator 3, an electrolytic polishing device, and a magnetic particle grinding and polishing device 17, and the workpiece to be processed is mounted on the vertical milling machine workbench 6.
[0024] The ultrasonic generator 3 is clamped on the spindle chuck of the vertical milling machine, and the ultrasonic generator 3 is connected to the ultrasonic power supply 4 through the conductive slip ring 14 . When deburring the hole edge of the workpiece to be processed on the vertical milling machine table 6, the rotation of the vertical milling machine spindle can drive the ultrasonic generator 3 to rotate, thereby forming a rotating ultrasonic wave.
[0025] The ma...

The invention relates to a device for performing electrolytic rotating ultrasonic magnetic composite removal on hole edge burrs. The device comprises a vertical milling machine, an ultrasonic generator, an electrolytic polishing device and a magnetic particle grinding and polishing device; the ultrasonic generator is clamped on a main shaft clamping head of the vertical milling machine; the part below the ultrasonic generator is connected with the magnetic particle grinding and polishing device; the electrolytic polishing device is fixedly connected with a main shaft outer cylinder of the vertical milling machine; a to-be-processed workpiece on a workbench of the vertical milling machine is subjected to hole edge burr removal, the electrolytic polishing device electrolyzes the surface of the to-be-processed workpiece, a passivation film with the hardness less than that of a to-be-processed workpiece substrate is formed, the rotating magnetic particle grinding and polishing device removes the passivation film formed in the electrolysis process, so forth, rotating ultrasonic wave generated after the ultrasonic generator rotates provides intermittent grinding pressure to the magneticgrinding and polishing device. The effect of removing the hole edge burrs from hard alloy is good and the working efficiency is improved greatly.
Description
technical field [0001] The invention relates to the technical field of ultra-precision machining, in particular to a device for removing burrs on the edge of a hole by electrolysis, rotation, ultrasonic and magnetic combination. Background technique [0002] Cemented carbide is widely used in many fields such as aerospace and ships due to its high strength and good corrosion resistance. However, when drilling cemented carbide plates, the exit of the drill hole will form sharper burrs with higher hardness. Due to the existence of burrs, the quality of the surface of the workpiece hole is greatly reduced, which has a negative impact on the use of the workpiece. , For example, in the bolt connection, the burr on the edge of the hole will cause the bolt to be loose and the pressure surface of the screw cannot be in good contact with the connected parts, resulting in loosening during work, affecting production and work safety. [0003] The traditional method of removing burrs on...
