AUTOMATED SYSTEM FOR ULTRASONIC PRESS-FITTING OF ROLLING CUTTER BIT TEETH

摘要

Questions are considered/or improving the efficiency of press-fitting rolling cutter bit teeth based on using high-frequency low-amplitude ultrasonic vibrations that intensify the assembly processes. A computer automated system is developed for scientific studies of the process of ultrasonic assembly (ultrasonic press-fitting) of hard alloy bits with simultaneous diagnosis of quality indices for the joint formed. Experimental studies are performed for the press-fitting force and strength properties of joints assembled by traditional methods and with the action of ultrasound that have shown a reduction in press-fitting force by up to 20% with a simultaneous increase in strength by 5%.
