Ultrasonic vibration sleeve reaming machining device applied to air drill

Abstract

The invention discloses an ultrasonic vibration sleeve reaming machining device applied to an air drill. The device comprises a slip ring, a front cover plate, a ceramic plate A, a ceramic plate B, a rear cover plate, a flange plate, a retainer ring, a manual air drill, a drill shaft sleeve, a spring chuck and a fastening cap; the main shaft of the manual air drill is connected into an internal thread hole of the front cover plate; after the ceramic plate A and the ceramic plate B are sequentially sleeved at the external thread section of the front cover plate, the front cover plate is in threaded connection into an internal thread hole of the rear cover plate; an inner ring of the slip ring is arranged on the rear cover plate, and an outer ring of the slip ring is connected with the retainer ring and the flange plate through bolts; and the inner conical section of one end of the drill shaft sleeve is connected with the outer cylindrical section of the spring chuck, the outer cylindrical section of the other end of the drill shaft sleeve is thermally fed into the inner cylindrical section of the front cover plate, and the chuck section of the spring chuck chucks a reamer or a coredrill and is finally locked through the fastening cap. By assembly design of the spring chuck, the clamped tool bit form is varied, a transducer, the main shaft of a common air drill and a cutter aredetached conveniently, and the rotary precision of the whole air drill tool is ensured.

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 vibrating sleeve reaming processing device is particularly suitable for processing large holes of fasteners with high quality, high efficiency and low cost in the laminated carbon fiber composite material and titanium alloy. It belongs to the technical field of ultrasonic vibration cutting processing technology and equipment components. 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, and improving surface quality and shape accuracy. However,...

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

[0003] The applicant has submitted a patent application titled "An Ultrasonic Vibration Sleeve Reaming Device Applied to Air Drill" with application number 201010543592.3 on November 15, 2010. In this patent, the tool (reamer or casing drill) The connection with the main shaft of the air drill is a threaded connection, and only the cutter with a threaded head can be installed, and many cutters all adopt inch threads, and many cutters have to be customized. tool or nesting drill) and the manual air drill spindle are connected by a spring chuck assembly, which not only makes the cutter head of the clampable tool various in form, but also facilitates the disassembly of the transducer and the ordinary air drill spindle and tool, ensuring The rotation accuracy of the entire air drilling tool, this patent application is an improvement on the previous patent application
