Technical Field

The invention relates to the technical field of processing technology, in particular to an intermittent axial torsion combined type mechanical torsion vibration table.

Background

The vibration machining is applied to mechanical machining such as turning, drilling, grinding and the like as an efficient machining process, is beneficial to reducing cutting force and cutting heat, reducing the conditions of cutter sticking and cutter collapsing, and can improve machining efficiency, prolong the service life of a cutter and obtain a high-quality machined surface. From the difference of vibration sources, the method can be divided into two realization forms of workpiece vibration and cutter vibration; the difference in vibration direction can be divided into axial vibration and torsional vibration. For difficult-to-machine materials represented by fiber reinforced composite materials, the technology is beneficial to reducing cutting defects, such as in drilling, high-quality drilling is difficult to obtain for carbon fiber composite materials because fibers are easy to break in the machining process. The ultrasonic frequency or non-ultrasonic frequency torsional vibration of the axial direction of the drill bit is applied to the drill bit or the workpiece, so that the cutting track can be changed periodically, the fiber breakage is effectively inhibited, and the processing effect is improved.

For example, a composite vibration drilling device of patent No. CN201610002983.1 superimposes ultrasonic frequency torsional vibration on a drill bit, and the technical purpose of the composite vibration drilling device is to satisfy non-metal hard and brittle materials and hard-to-cut metal materials, but the requirements on production, manufacture, installation and maintenance of a drilling main shaft are high.
