Embodiment Construction

[0019] The embodiments described below with reference to the accompanying drawings are exemplary, and are only used to explain the present invention, and cannot be construed as limiting the present invention.

[0020] The embodiment of the present invention: such as Figure 1-Figure 4 As shown, a longitudinal torsion composite ultrasonic vibration drilling device includes turning equipment. The turning equipment is equipped with a longitudinal torsion composite vibration mechanism. The turning equipment can use the equipment in the prior art. The longitudinal torsion composite vibration mechanism includes a flange. 1. Morse cone 2, horn 3 and piezoelectric ceramic sheet 4. Flange 1 is arranged on Morse cone 2. The two are coaxially arranged and rigidly connected. The shank end of Morse cone 2 is elastic The chuck 5, the connection between the two is preferably threaded, the elastic chuck 5 is equipped with a lock nut 6, and the twist drill 7 is plug-connected to the elastic chuck...

Abstract

The invention discloses a longitudinally torsional compound ultrasonic vibration drilling device. The longitudinally torsional compound ultrasonic vibration drilling device includes turning equipment,the turning equipment is provided with a longitudinally torsional compound vibration mechanism, the longitudinally torsional compound vibration mechanism includes a flange plate, a Morse taper, at least three amplitude transformers and piezoelectric ceramic pieces, the flange plate is arranged on the Morse taper, the flange plate and the Morse taper are coaxially arranged, the taper-shank end ofthe Morse taper is provided with an elastic clamp cylinder, the elastic clamp cylinder is provided with a locking nut, a twist drill is connected with the elastic clamp cylinder in an inserting mode,and is fixed to the elastic clamp cylinder through the locking nut, the at least three amplitude transformers are uniformly distributed on the flange plate, and are located on the same side with the taper tail of the Morse taper, and the piezoelectric ceramic pieces are installed on the amplitude transformers correspondingly. According to the longitudinally torsional compound ultrasonic vibrationdrilling device, the longitudinal vibration oblique angle is introduced into and converged on the flange plate through the longitudinally torsional compound vibration mechanism to realize longitudinally torsional compound vibration drilling of the twist drill.

Description

Technical field [0001] The invention relates to a drilling device, in particular to a longitudinal torsion composite ultrasonic vibration drilling device. Background technique [0002] In the field of mechanical processing, drilling as a simple and commonly used processing method has been more and more widely used, but some of its own characteristics also bring to the processing quality defects that cannot be overcome by conventional processing conditions, such as hole surface processing Poor quality, large concentricity error, large hole size deviation, large drilling force, high drilling temperature, short tool life and other defects. Difficult chip breaking when drilling viscous materials such as stainless steel and titanium alloys leads to scratches on the surface of the workpiece. [0003] Ultrasonic vibration drilling has a vibration frequency of more than 20,000 Hz and an amplitude of 3-20 microns. It can transform continuous cutting into intermittent cutting. It has essenti...
