A flexible scraper

Abstract

The invention discloses a flexible scraper. The flexible scraper comprises a spindle, a tool handle and a scraping head, wherein the tool handle is connected to one end of the spindle, and the scraping head is connected to the other end of the spindle and provided with at least two floating blade sets, each floating blade set is provided with a rough scraping blade and a fine scraping blade, a first through hole is axially formed in the spindle, an ejector rod mechanism is arranged in the first through hole, a second through hole which is coaxial with the first through hole is formed in the scraping head, a blade adjusting mechanism is arranged in the second through hole, and the ejector rod mechanism abuts against and is matched with the blade adjusting mechanism. The spindle is sleeved with a cooling chip removal sleeve, at least one chip punching hole is formed in the end, close to the scraping head, of the cooling chip removal sleeve, and a cooling liquid pipe is arranged on the cooling chip removal sleeve. According to the flexible scraper, the floating blade sets are adopted and provided with the rough scraping blades and the fine scraping blades, rough machining and fine machining are finished at the same time in one machining, and therefore machining accuracy is improved. By the arrangement of the chip punching holes, chips are more smoothly removed, and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of machining cutting tools, in particular to a flexible scraper. Background technique [0002] Machine tool processing refers to the processing of raw materials with machine tools; the cutting process of machine tools is realized by the relative movement between the tool and the workpiece. Machine tool processing can be divided into ordinary lathe processing and CNC lathe processing according to different machine tools; with the continuous development of machine tool processing technology, CNC lathes have gradually replaced ordinary lathes. The use of CNC lathe processing not only improves the production effect of parts and products, but also improves the precision of processing to meet the processing needs of fine processing and precision parts. [0003] The blades of the existing scraping blades are mostly fixed to the scraping head, and are in hard contact with the workpiece during the scraping process, ...

AI Technical Summary

Problems solved by technology

[0003] The blades of the existing scrapers are mostly fixed with the scraper head, and they are in hard contact with the workpiece during the scraping process, which may easily cause scratches on the surface of the workpiece, and the processing accuracy is low

In addition, during the processing, the high-speed friction between the tool and the workpiece will generate a lot of heat; in order to ensure the normal processing, it is necessary to use coolant to cool the workpiece, and the debris generated by the scraping process will enter the cooling with the coolant. The liquid circulation system will cause damage to the equipment and affect the service life of the equipment
