Adjustable face scraping tool

Abstract

The invention relates to machining tools, in particular to an adjustable face scraping tool. A through hole connected with a tool bar is formed in a tool body of the adjustable face scraping tool. Cantilevers provided with sliding grooves are arranged at the two ends of the tool body correspondingly, and length unit numerical scales are arranged on the cantilevers. A tool apron is slidably connected with the tool body. The tool apron is provided with blade installation grooves and length unit numerical scales. The length unit numerical scales on the tool apron correspond to the length unit numerical scales on the cantilevers. According to the adjustable face scraping tool, the tool apron can slide on the tool body, the machining diameter can be adjusted conveniently through the length unit numerical scales on the tool apron and the length unit numerical scales on the tool body, and the tool body is installed on the tool bar through a screw, so that disassembly and assembly are convenient; and in addition, when round planes with different diameters are machined through scraping, the situation that in order to meet the dimension requirement of machined faces, blades of different dimensions need to be replaced or cutting edges of the blades need to be sharpened is avoided, a user just needs to adjust the displacement numerical scale of the tool apron on the tool body, and thus the machining efficiency is improved.

Description

technical field [0001] The invention relates to a machining cutter, in particular to an adjustable scraping cutter. Background technique [0002] In mechanical processing, there are often a large number of workpieces that need to be scraped on the end face of the hole, and the scraped surface has a verticality requirement for the hole. At present, the scraping knife equipped with high-speed steel blades is generally used for processing. The disadvantages of this tool The reason is that the length of the cutting edge of the blade is a fixed value. When scraping circular planes with different diameters, it is necessary to replace the blades of different sizes or sharpen the cutting edges of the blades to meet the size requirements of the surface to be scraped. In addition, the scraping surface with this structure During the cutting process of the knife, the cutting force generated by the long cutting edge is very large, not only the machining vibration is large, the roughness ...

[0002] In mechanical processing, there are often a large number of workpieces that need to be scraped on the end face of the hole, and the scraped surface has a verticality requirement for the hole. At present, the scraping knife equipped with high-speed steel blades is generally used for processing. The disadvantages of this tool The reason is that the length of the cutting edge of the blade is a fixed value. When scraping circular planes with different diameters, it is necessary to replace the blades of different sizes or sharpen the cutting edges of the blades to meet the size requirements of the surface to be scraped. In addition, the scraping surface with this structure During the cutting process of the knife, the cutting force generated by the long cutting edge is very large, not only the machining vibration is large, the roughness of the machined surface is high, it is easy to cause chipping, and the entire blade must be reground after chipping, all of the above situations will lead to Production preparation time is too long
