Numerical control extrusion screw tapping thread grinding machine

Abstract

The invention discloses a numerical control extrusion screw tapping thread grinding machine. The numerical control extrusion screw tapping thread grinding machine comprises a controller and a mechanical system; the controller is electrically connected with an A-axis servo motor, an X-axis servo motor, a Y-axis servo motor and a C-axis servo motor through drivers; the mechanical system comprises a lathe bed, a head support used for fixing a workpiece, a working table, a grinding carriage and a trimming wheel; and the A-axis servo motor is connected with a main shaft of the head support and drives the head support to drive the workpiece to rotate in the axial direction, the X-axis servo motor is installed on the lathe bed and drives the working table to move left and right through a second ball screw, the Y-axis servo motor drives the grinding carriage through a third ball screw so as to driven a grinding wheel to move front and back, and the C-axis servo motor drives the trimming wheel through a fourth ball screw to conduct automatic cutting supplementing on the trimming amount. The four-axis numerical control grinding machine is adopted, numerical control operation can be carried out on motion and positioning of all components, the automatic degree is high, the grinding wheel trimming accuracy is high, the working surface of the grinding wheel is smooth, and the machining accuracy and efficiency are greatly improved.

Description

technical field [0001] The invention relates to the field of grinding machines, in particular to a numerically controlled extruding wire tapping thread grinding machine. Background technique [0002] Grinding machine is a common mechanical processing equipment. Ordinary grinding machines use grinding wheels to grind the surface of workpieces to improve the surface finish and precision of workpieces. Ordinary grinding machines have very small grinding allowances for workpieces, and the productivity is very low. It is impossible Grinding and shaping the workpiece directly. Because of the traditional grinding, the grinding wheel wears quickly. The grinding wheel must be dressed frequently with the help of grinding wheel dressing, so that the grinding wheel can regain the shape accuracy and sharpness of the surface. After dressing, due to the reduction in the size of the grinding wheel Small, the compensation amount of the grinding wheel is difficult to control, which affects th...

[0002] Grinding machine is a common mechanical processing equipment. Ordinary grinding machines use grinding wheels to grind the surface of workpieces to improve the surface finish and precision of workpieces. Ordinary grinding machines have very small grinding allowances for workpieces, and the productivity is very low. It is impossible Grinding and shaping the workpiece directly. Because of the traditional grinding, the grinding wheel wears quickly. The grinding wheel must be dressed frequently with the help of grinding wheel dressing, so that the grinding wheel can regain the shape accuracy and sharpness of the surface. After dressing, due to the reduction in the size of the grinding wheel Small, the compensation amount of the grinding wheel is difficult to control, which affects the machining accuracy of the grinding, and has a greater impact on the profile grinding

[0003] The traditional thread grinder is manually operated, and the relief grinding of the thread part is controlled by the shape of the cam. There are many items that need to be adjusted manually, the operation is more troublesome, the processing efficiency is relatively low, and the accuracy cannot meet the requirements of high-quality taps.
