Scraping device for curved-surface shaft sleeve

Abstract

A scraping device for a curved-surface shaft sleeve is mainly composed of a rotary disc handle, double positioning rods, a scraper head, a locking handle, a dial indicator head, a stop iron, hand wheel screws and adjustable pads. The scraping device is characterized in that a workpiece is mounted on the double rods, the height is adjusted through the adjustable pads, and a screw spiral transmission principle is used for achieving scraper feeding; and after the feeding amount is controlled and locked when the dial indicator head is in contact with the stop iron, scraping is performed, and the positioning rods of a rotary disc can be adjusted in order to meet requirements of workpieces of different specifications. The scraping device has the advantages of being convenient to mount and dismount, capable of achieving scraping mechanization, meeting machining requirements of incomplete curved-surface shaft sleeves and meeting workpiece surface quality, cylindricity and roundness requirements, high in dial indicator feeding accuracy, simple in structure, convenient to operate and high in accuracy and efficiency.

Description

technical field [0001] The invention belongs to the field of mechanical processing auxiliary equipment, and more precisely relates to a scraping device for shaft sleeves with different curved surfaces. Background technique [0002] Ordinary grinding machines can only process parts with a complete regular curved surface bushing shape during processing. If the shape of the part is an irregular curved surface bushing shape, it cannot be processed on an ordinary grinder, let alone a part similar to an 8-shaped gear pump bushing Therefore, it is imminent to design a processing device that is easy to assemble and disassemble, and can process the shape of hollow irregular curved surface bushings, and replace grinding by cutting. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages, and provide a processing device with simple production process, low price, convenient assembly and disassembly, and capable of processin...

Problems solved by technology

[0002] Ordinary grinding machines can only process parts with a complete regular curved surface bushing shape during processing. If the shape of the part is an irregular curved surface bushing shape, it cannot be processed on an ordinary grinder, let alone a part similar to an 8-shaped gear pump bushing. Shape grinding, therefore, it is imminent to design a processing device that is easy to assemble and disassemble, and can process the shape of hollow irregular curved surface bushings by cutting instead of grinding.
