Description

Technical Field

[0001] The utility model relates to the technical field of precision grinding machines, and particularly refers to an angle adjusting mechanism for a grinding wheel of a grinding machine spindle. Background Art

[0002] Precision grinding machines are used for grinding precision complex surfaces, including precision grinding of straight lines, arcs, and curves. During the grinding process, the movement of the workpiece can be controlled manually or by editing a program to achieve the purpose of machining the surface.

[0003] Currently, the spindle motors of precision grinding machines are all horizontally placed laterally or vertically fixed on the machine table, and the structural relationship with the workpiece clamping table is parallel or perpendicular. However, the cross-section of the current grinding wheels is a conical structure, and the unilateral shape is an inclined plane. When machining a workpiece, an angle is formed between the inclined plane of the grinding wheel and the workpiece machining surface. With the spindle motor angle fixed, the angle of the machined workpiece can only be consistent with the slope of the grinding wheel cross-section, and right angles or other angles cannot be machined, affecting the application range of the workpiece. Therefore, a mechanism for adjusting the angle of the spindle motor is designed to compensate for the angle of the grinding wheel, thereby meeting the technical requirements of the workpiece. Summary of the Utility Model

[0004] The purpose of the utility model is to address the deficiencies of the prior art and provide an angle adjusting mechanism for a grinding wheel of a grinding machine spindle. Its structure is scientific and simple. By adopting an adjustable angle movable mechanism for the fixing method of the spindle motor of the precision grinding machine, the angle between the spindle motor and the workpiece clamping table can be adjusted arbitrarily according to the angle of the conical surface of the grinding wheel, playing a role in compensating for this angle of the conical surface of the grinding wheel, so that the conical surface of the grinding wheel is consistent with the required machining angle of the workpiece, increasing the machining range of the workpiece, and improving the performance of the grinding machine.

A spindle motor is arranged on the spindle seat. A grinding wheel is fixed at the end of the spindle motor. Activity shafts are symmetrically arranged on two of the sides of the spindle seat. An oil-impregnated bushing is arranged on the activity shaft, and the oil-impregnated bushing is fixed in the activity hole on the side support plate. The adjusting mechanism is any one of a worm and worm gear adjusting mechanism and a screw and nut adjusting mechanism. The worm and worm gear adjusting mechanism is fixed on the side of the side support plate, and the screw and nut adjusting mechanism is fixed on one side of the spindle seat. A scale is also arranged on the upper surface of the spindle seat.

[0007] Furthermore, the activity shaft and the spindle of the spindle motor are vertically staggered.

[0008] Further, the turbine output shaft on the worm and worm gear adjusting mechanism is connected to the movable shaft through an oil-impregnated bushing, and an adjusting handle is provided on the worm of the worm and worm gear adjusting mechanism.

[0009] Further, the screw-nut adjusting mechanism includes an adjusting seat, the adjusting seat is fixedly connected to the main shaft seat, a screw connecting plate is fixed on the adjusting seat, an adjusting screw is movably connected to the screw connecting plate, a nut plate is threadedly connected to the adjusting screw, and the nut plate is also fixedly connected to the connecting plate.
