Combined cutter for skiving and rolling

Abstract

The invention provides a combined cutter for skiving and rolling. The combined cutter comprises a driving shaft (1) and a rolling part (2) and a skiving part (3) which are installed on the driving shaft (1); the driving shaft (1) can drive the rolling part (2) and the skiving part (3) to turn; and a central hole (11) is formed in the center of the driving shaft (1). By virtue of the technical scheme provided by the invention, the turning inertia of the combined cuter for skiving and rolling is reduced and the stability and reliability of the combined cutter in work are improved. As a result, a whole roller cage is good in ductility and a roller groove is high in wear resistance to increase the strength of adjusting screw rods of an assembly base of a skiving knife holder, avoid cracking of the adjusting screw rods and guarantee the continuity and reliability of the skiving and rolling operation. Meanwhile, the combined cutter is simple in connecting and installing structures, and capable of effectively reducing weight and turning inertia of the skiving cutter, reducing manufacturing difficulty and improving production efficiency.

Description

technical field [0001] The invention relates to the field of engineering machinery, more specifically, to a scraping and rolling combined cutter. Background technique [0002] At present, most deep hole machining uses a single tool. Because the tool shaft of the deep hole machining tool is very long, the tool has natural flexible deformation and poor stability. It is easy to scratch the finished surface. When the tool is damaged or the machine tool is stopped midway during the processing, the tool will return to damage the workpiece and cause the workpiece to be scrapped. [0003] For the machining of the inner hole of the oil cylinder with a diameter larger than φ450mm, the process of rough boring and then honing is generally used for processing, but the efficiency of honing is very low; to realize the smooth inner hole processing of the φ450mm scraping roller, it is first necessary to design and manufacture the φ450mm scraping roller Cutter head, the scraping roller head...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the complex structure of the scraping and rolling combination cutter in the above-mentioned prior art, the overall weight of the cutter is large, which affects the processing quality, the design of the scraper reset device is unreasonable, increases the difficulty of processing and installation, is not easy to maintain and disassemble and replace, and affects production efficiency. etc., or at least one of them, the present invention provides a combined scraping and rolling cutter, which can effectively overcome the above-mentioned problems in the prior art
