Double-station numerical control worm grinding wheel gear grinding machine

Abstract

The invention discloses a double-station numerical control worm grinding wheel gear grinding machine which comprises a first lathe bed part and a second lathe bed part. A Y-axis guide rail and a grinding head stand column are arranged on the first lathe bed part, and the grinding head stand column is installed on the Y-axis guide rail through a Y-axis driving mechanism; a Z-axis guide rail and a Z-axis sliding table are arranged on the front side of the grinding head part stand column, a spiral angle rotating part capable of rotating around the A axis is arranged on the front side of the Z-axis sliding table, and a grinding wheel assembly is arranged on the front side of the spiral angle rotating part; an X1-axis guide rail, an X2-axis guide rail, a first stand column and a second stand column are arranged on the second lathe bed part, the X1-axis guide rail and the X2-axis guide rail are parallel to each other, a first workpiece rotary table is arranged on the rear side of the first stand column, and a second workpiece rotary table is arranged on the rear side of the second stand column. The first workpiece rotary table and the second workpiece rotary table are provided with a vertical first workpiece rotary shaft C1 and a vertical second workpiece rotary shaft C2 respectively. The device has the advantages of stable work, reliable performance, short transmission chain, good rigidity, high precision, high efficiency and the like.

Description

technical field [0001] The application relates to the technical field of numerical control machine tools, in particular to a double-station numerical control worm grinding wheel gear grinding machine. Background technique [0002] At present, the changes in the automobile industry can be said to be "revolutionary", and it is an indisputable fact that electric vehicles are developing rapidly and gradually replacing traditional fuel vehicles. [0003] Generally, the maximum speed of the traditional fuel vehicle engine is 8000r / min, while the motor speed of the electric vehicle can reach up to 28000r / min, and the rotation speed is from relatively low speed to super high speed. Strict requirements, improving gear accuracy and reducing transmission noise are the problems that the electric vehicle industry must face. [0004] During the production of gears using the generative grinding method, the cutting speed must be maintained between 63-80 m / s to ensure high productivity. Th...

Problems solved by technology

However, this kind of double-spindle gear grinding machine cannot replace the workpiece within five seconds. The reason is that the two spindles are installed on a turntable. Since the position of the worktable is not precisely controlled during the indexing process, it must be used Hydraulic locking ensures precision. When turning, you must first loosen the clamp, lift, rotate, reach the new position and lock, and it takes more time than turning

This method has reached the limit, there is no possibility of faster
