Problems solved by technology

However, at the same time as the efficient machining of workpieces and the improvement of automation, the increase of cutting force, the increase of cutting heat, the decrease of tool durability, and the problems of chip removal and chip breaking have seriously affected the development of high-efficiency machining.
The patent "Milling cutter for difficult-to-machine materials" (patent application number 201310013775.8) cleverly uses the planetary gear train structure, which effectively reduces tool wear and improves tool life. However, due to the limitation of its own structure, the patent can only achieve reverse rolling Cutting cutting, under hobbing cutting, pure free hobbing cutting, over hobbing cutting and other four cutting modes, and the change of cutting mode is realized by manually changing the gear

Abstract

The invention belongs to the technical field of mechanical machining, and particular relates to a stepless speed-regulation hobbing machine tool. The differential stepless speed-regulation multimode hobbing machine tool adopts the technical scheme as follows: a control driving system (26) is connected with a main shaft speed regulation motor (2), a speed regulation motor (9), an electromagnetic clutch (10), a transverse feeding worktable (14), a longitudinal feeding worktable (15) and a machine tool lift platform (16) through a data area driving line (40), the speed variation and direction changing of the main shaft speed regulation motor (2) and the speed regulation motor (9), the opening and closing of the electromagnetic clutch (10), the inward-outward motion of the transverse feeding worktable (14), the leftward-rightward motion of the longitudinal feeding worktable (15) and the up-down motion of the machine tool lift platform (16) are controlled and driven according to an input command. By adopting the differential stepless speed-regulation multimode hobbing machine tool, different cutting forms can be realized, the cutting force can be effectively reduced, the cutting heat can be reduced, the duration of the cutter can be improved, smoothness in clippings discharging is realized, and the clippings can be cut off in time.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a stepless speed regulating hobbing machine tool. Background technique [0002] With the development of the mechanical processing industry, the requirements for processing efficiency and automation are getting higher and higher. However, with the high-efficiency machining of workpieces and the improvement of automation, the increase of cutting force, the increase of cutting heat, the decrease of tool durability, and the problems of chip removal and chip breaking have seriously affected the development of high-efficiency machining. The patent "Milling cutter for difficult-to-machine materials" (patent application number 201310013775.8) cleverly uses the planetary gear train structure, which effectively reduces tool wear and improves tool life. However, due to the limitation of its own structure, the patent can only achieve reverse rolling Cutting cutting...
