Technical Field

[0001] The utility model relates to the technical field of machining tools, in particular to an inner plane scraper for machining. Background Art

[0002] A machining scraper is a tool used in industrial production and processing. It is installed on a machining center to process the inside of metal parts. Scrapers are widely used in the field of metal internal processing technology and are mainly used for scraping and finishing the surface of workpieces. The main functions of scrapers include removing substances that affect mechanical accuracy, correcting machining errors, reducing surface roughness values, and improving contact accuracy and geometric accuracy, thereby improving the matching stiffness, lubrication performance, mechanical benefit and service life of machine tools. Scrapers can be divided into many types according to the different scraping surfaces of the workpiece, such as flat scrapers, triangular scrapers, crescent scrapers, etc.

[0003] During machining, the scraper and the workpiece will heat up due to constant friction, so they need to be cooled by cutting fluid or coolant. Existing scraper cooling methods mostly spray coolant from the outside to the processing position, which can only cool the outside of the cutter body, while the inside of the cutter body still heats up, which will affect the use of the cutter body.

The blade 2 may include a first blade and a second blade, and the first blade and the second blade are centrally symmetrically arranged. That is, the blade 2 is arranged into two scraping ends, and after one end is worn, the other end can be disassembled and replaced for continued use, thereby extending the service life of the blade 2. The plane where the mounting groove is located is inclined, and one end where the blade 2 is located is located in front of the other end during the scraping movement. Thereby, the waste chips generated during the processing process can be effectively discharged.
