Ultrasonic vibrating trepanning reamer machining device applied to pneumatic drill

Abstract

The invention discloses an ultrasonic vibrating trepanning reamer machining device applied to a pneumatic drill, which comprises a slide ring, a front cover plate, an A ceramic piece, a B ceramic piece, a back cover plate, a flange plate, a baffle ring, a reamer or a trepanning drill. The main shaft of the pneumatic drill is connected in an internal threaded hole of the front cover plate, an external threaded section of the front cover plate is sequentially sheathed with the A ceramic piece and the B ceramic piece, the external threaded section is arranged in a threaded hole of the back coverplate, and the other end of the front cover plate is connected with the reamer or a trepanning cutter; and an inner ring of the slide ring is arranged on the outer edge of the back cover plate, the baffle ring is arranged between an outer ring of the slide ring and the flange plate, and the shell of the pneumatic drill is connected with the flange plate. The device can be used for machining a large-pore, high-quality, high-efficiency and low-cost fastening piece hole of a composite titanium alloy laminated material.

Description

Technical field [0001] The invention relates to an ultrasonic vibration drilling device, and more particularly, to an ultrasonic vibration sleeve reaming processing device applied to a pneumatic drill. The ultrasonic vibration drilling device is more suitable for machining large holes of fasteners with high-quality, high-efficiency and low-cost laminated carbon fiber composite materials and titanium alloys. Background technique [0002] Ultrasonic vibration cutting is to add an ultrasonic vibration to the cutting tool, so that the original continuous cutting process becomes intermittent. The cutting method with special cutting effect was first proposed by Japanese scholars. Ultrasonic vibration cutting has the unique advantages of reducing cutting force and cutting temperature, improving surface quality and shape and position accuracy. However, the previous vibration processing devices have disadvantages such as complicated structure, large volume, and inability to rotate. They ...

AI Technical Summary

Problems solved by technology

However, the previous vibratory processing devices have disadvantages such as complex structure, large volume, and inability to rotate, and are usually used on machine tools or various machining centers.

Therefore, the portability of the vibration device is poor, which limits the application of vibration technology in light and portable hand tools, especially at present, ordinary air drills in aircraft skin assembly sites cannot use the advantages of vibration technology to process a large number of difficult-to-process laminated materials with high quality and high efficiency. Low Cost Fastener Hole Machining
