Oblique cam type torsional vibrator for vibrating hole formation

Abstract

The oblique cam type torsional vibrator for vibrating hole formation consists of a casing comprising a upper part and a lower part screwed together, a driving assemble, an elastic coupling, a vibration generator assemble and an output shaft. It has right end cover and left end cover in the joint of the two casing parts, driving shaft on two bearings, two locating parts and inclined cam on the driving shaft, balance wheel on a shifting fork, driving belt wheel connected to the output shaft of the motor, driven belt wheel, two V-belts between the driving belt wheel and the driven belt wheel, and connecting shaft connected to the shifting fork and the elastic coupling. The torsional vibrator of the present invention may be installed onto a bench tapping machine or bench drilling machine for vibration tapping and vibration reaming, and the torsional vibrating motor may be powered through one collecting ring installed to the top of the upper casing part.

Description

technical field [0001] The invention relates to a torsional vibrator, in particular to an oblique cam type torsional vibrator used for vibratory hole making (vibration tapping and vibration reaming), which belongs to metal cutting processing and metal cutting equipment components. Background technique [0002] Under the existing technical conditions, the threaded hole processing of difficult-to-machine materials (such as stainless steel, high-strength steel, titanium alloy and high-temperature alloy, etc.) generally adopts the processing method of manual tapping by workers. During the tapping process, the tap is often due to excessive tapping torque. Large and broken, it is easy to cause scrapping of the workpiece. Vibration tapping can significantly reduce the tapping torque, improve tool life and thread quality, and is an effective technical means to solve the processing problems of threaded holes of difficult-to-machine materials and small threaded holes of ordinary mater...

AI Technical Summary

Problems solved by technology

[0004] In the existing mechanical low-frequency torsional vibrator, the vibration force of the torsional vibration mechanism is unbalanced, the layered structure leads to additional overturning torque, and the unreasonable use of high-level structures leads to gap shock and vibration, etc., resulting in There are large harmful vibrations and noises during the operation of the equipment, which will affect the service life of the system

In addition, the existing torsional vibration mechanism cannot adjust the amplitude, which limits the optimization of process parameters and application range of vibration tapping equipment
