New high-efficiency CNC gear grinding machine

Abstract

The invention discloses a novel efficient numerical control gear grinding machine which comprises a machine frame, a left-right workbench, a front-rear workbench, a Z-axis sliding mechanism, a C-axis workpiece clamping and holding mechanism, an X-axis sliding mechanism, a B-axis rotating mechanism, a V-axis trimming mechanism, a U-axis trimming mechanism and a grinding head mechanism. The left-right workbench is horizontally arranged at the front portion of the machine frame; the C-axis workpiece clamping and holding mechanism is arranged on the left-right workbench; the front-rear workbench is longitudinally arranged at the tail portion of the machine frame; the grinding head mechanism is arranged on the front-rear workbench. The novel efficient numerical control gear grinding machine is ingenious and reasonable in design, easy to operate, multifunctional, capable of grinding ordinary spur gears, bevel gears, screw rods, worms and ring surface worms efficiently, multipurpose and wide in application range, has the function of trimming grinding heads, can efficiently trim the grinding heads of any contour, greatly improves rigidity of the grinding heads, effectively improves machining accuracy, and is simple in overall structure, easy to manufacture and produce, and beneficial to being popularized and applied widely.

Description

technical field [0001] The invention relates to the technical field of worm gear grinding, in particular to a novel high-efficiency numerical control gear grinding machine. Background technique [0002] Worm drive is a commonly used transmission type in mechanical equipment. It has the characteristics of wide range of transmission ratio (usually the first-stage transmission ratio can reach 5-100), compact structure, small size, smooth movement, and low noise. It has the characteristics of high bearing capacity, high transmission efficiency, long life, and small average indexing error, so it is widely used. [0003] According to the structural characteristics and processing principle, the worm drive can be divided into two categories: ordinary cylindrical worm drive and toroidal worm drive. [0004] Among them, ordinary cylindrical worm transmission includes Archimedes cylindrical worm (ZA type), involute cylindrical worm (ZI type), normal straight profile worm (ZN) type, co...

Problems solved by technology

[0007] Although some existing worm grinding machines can roughly meet the requirements of ordinary gear grinding, the design is not ingenious, the transmission structure is simple, the processing process is relatively slow, the processing accuracy is not high, the processing range is single, and the power consumption is large, and the processing cost is high; In particular, if the gear grinding machine equipped with a numerical control system does not have an automatic gear repair device, its grinding efficiency will be greatly reduced. The traditional worm grinding machine can no longer adapt to and meet the needs of the current market.
