Double-station efficient worm-grinding-wheel computer numerical control gear grinding machine

Abstract

The invention provides a double-station efficient worm-grinding-wheel computer numerical control gear grinding machine which comprises a moving workbench, double workpiece spindles, a vertical column,a vertical sliding plate box, a spiral disc, a grinding wheel spindle and a machine tool body, wherein the moving workbench is mounted at the front part of the machine tool body through a horizontallinear guiding guide positioned in the left-right direction; the double workpiece spindles are mounted on the moving workbench along the left-right direction of the moving workbench; two rotating axesof the double workpiece spindles are in the perpendicular state; the bottom of the vertical column is mounted at the rear part of the machine tool body through a linear guiding rail positioned in thefront-rear horizontal direction; the vertical sliding plate box is mounted in an inner cavity of the vertical column through a linear guiding rail positioned in the upper-lower perpendicular direction; the spiral disc is mounted at the front part of the vertical sliding plate box through a front-rear horizontal rotating support in the vertical sliding plate box; the grinding wheel spindle is mounted at the front part of the spiral disc; and the rotating axis of the grinding disc spindle and that of the spiral disc intersect perpendicularly. According to the double-station efficient worm-grinding-wheel computer numerical control gear grinding machine provided by the invention, the double workpiece spindles are driven through the linear moving workbench to be exchanged; the overlap betweenthe grinding time and the auxiliary time for loading and unloading is achieved; and the workpiece spindle exchange time is short and the repeated positioning precision is high.

Description

technical field [0001] The invention belongs to the technical field of gear grinding, and in particular relates to a high-efficiency worm grinding wheel numerical control gear grinding machine with linear movement and exchange. Background technique [0002] As a transmission basic part, gears are widely used in many fields. With the development of social production, especially the continuous improvement of product quality and the continuous expansion of production scale in industries such as automobiles, efficient gear grinding technology and equipment have become the market The urgent need for high-precision gears with small and medium modules, the use of worm grinding wheel gear grinding machines can achieve high production efficiency under the premise of ensuring the processing quality, but for the processing of large quantities of gear parts in the automotive industry, it is hoped that there will be more High production efficiency to further reduce costs and enhance prod...

Problems solved by technology

[0003] Aiming at the problems of efficiency, precision and cost in the existing numerical control worm grinding wheel gear grinding machine, the present invention proposes a linear movement exchange double-station high-efficiency worm grinding wheel numerical control gear grinding machine. The workpiece spindle is exchanged to realize the overlapping of the part grinding time and the loading and unloading auxiliary time. At the same time, the left and right movement of the linear moving table and the up and down movement of the column can be controlled by the numerical control system to form the virtual axis of the axial movement of the grinding wheel spindle. This replaces the real axis of tangential serial tool movement as the main axis of the grinding wheel of the machine tool
