Multi-mode rolling cutter

Abstract

The invention discloses a multi-mode rolling cutter. The multi-mode rolling cutter comprises a cutter bit and a cutter body which are connected. The cutter body is of a hollow structure. The cutter bit comprises a cutter bit cover connected to the front end of the cutter body. A rolling ball is disposed on the front end face of the cutter bit cover. Part of the rolling ball extends out of the front end face of the cutter bit cover. The part, located in the cutter bit cover, of the rolling ball is supported by three support bearings. The three support bearings are respectively disposed in three grooves in the same surface of a support seat. The included angles among the three grooves are 120 degrees. The support seat is disposed in the cutter bit cover in a floating manner. The support seat contacts with a support plate disposed in the front end of the cutter body. The support plate is matched with a pressure adjusting mechanism which can move in the cutter body. The pressure adjusting mechanism is matched with a self-locking mechanism in the cutter body. A plurality of rolling columns are evenly disposed on the lateral side of the cutter bit cover. The rolling columns extend out of the cutter bit cover. The rolling columns is fixed by a limit mechanism fixed on the inner wall of the cutter bit cover. The multi-mode rolling cutter can roll rotary bodies and planes, cutter changing time is saved effectively, production efficiency is increased, and production cost is lowered.

Description

technical field [0001] The invention relates to a post-processing and surface strengthening technology of parts machining, in particular to a multi-mode rolling tool used in the post-processing of parts with complex surfaces. Background technique [0002] At present, with the development of science and technology, the requirements for the performance and surface quality of parts in today's mechanical field are increasing day by day, especially in some important processing industries, such as aerospace and so on. In order to meet the high fatigue resistance, corrosion resistance and wear resistance requirements of the parts, surface strengthening treatment is generally required after the parts are formed to improve their performance and surface quality. [0003] As a strengthening method, rolling is usually used to strengthen the surface quality of the processed workpiece. After rolling, the surface roughness of the workpiece is reduced, and the microhardness is relatively in...

Problems solved by technology

[0005] Most of the pressure adjustment mechanisms of rolling tools on the market are springs, and the compression of the spring is realized by thread feeding, so as to adjust the pressure. However, this device has a disadvantage, that is, during the rolling process, the tool is subjected to The reaction force will act on the thread, and the thread will be damaged after a long time, which will affect the accuracy of pressure adjustment and even make the tool invalid
