Grinder with grinding carriage capable of moving along Z1, Z2, X and B axes

Abstract

The invention relates to a grinder with a grinding carriage capable of moving along Z1, Z2, X and B axes, belonging to the field of machine tool fittings. The grinder is provided with a grinder body, wherein the grinder body is provided with a vertical planker, the vertical planker can reciprocate leftwards or rightwards along a guide rail in the Z1 axis of the grinder body, the vertical planker is provided with a vertical slider, a B-axis revolving axle is arranged between the vertical slider and the vertical planker, the vertical slider can rotate around the B-axis revolving axle for a certain degree, the vertical slider is provided with a cross planker, the cross planker can reciprocate leftwards or rightwards along a guide rail in the Z2 axis of the vertical slider, the cross planker is provided with a grinding wheel base with a grinding carriage, and the grinding wheel base with a grinding carriage can do a transverse feed movement along a guide rail in the X axis of the cross planker. The grinding carriage of the invention can reciprocate leftwards or rightwards along the Z1 axis, can rotate around the B axis of the machine tool, and can also ensures that the grinding carriage reciprocates along the Z2 axis of the machine tool and feeds along the X axis simultaneously after rotating the machine tool around the Z2 axis and the X axis for a certain degree without rotating the workpiece for a certain degree, thereby realizing a grinding carriage structure layout capable of completing the functions of grinding the long, inner and outer conical surfaces of the large axle part.

Description

technical field [0001] The invention relates to the field of machine tools, in particular to a grinding machine with a grinding wheel frame that can move along Z1, Z2, X, and B axes. Background technique [0002] As we all know, the grinding wheel frame of the existing grinding wheel frame mobile cylindrical grinding machine is fixed and can only move together with the Z-axis and X-axis movement axes of the machine tool. This structure greatly limits the processing range. To grind the 7:24 tool taper surface, it is necessary to rotate the grinding wheel frame or trim the grinding wheel into a bevel, and the grinding of the taper is also realized by two-axis interpolation of the Z axis and the X axis. The grinding of high cone surface can be satisfied, but if the cone surface with high precision requirements such as 7:24 internal and external tool cone surface and 1:12 bearing external cone surface are to be processed, such interpolation or plunge grinding method cannot meet ...

[0002] As we all know, the grinding wheel frame of the existing grinding wheel frame mobile cylindrical grinding machine is fixed and can only move together with the Z-axis and X-axis movement axes of the machine tool. This structure greatly limits the processing range.

To grind the 7:24 tool taper surface, it is necessary to rotate the grinding wheel frame or trim the grinding wheel into a bevel, and the grinding of the taper is also realized by two-axis interpolation of the Z axis and the X axis. The grinding of high cone surface can be satisfied, but if the cone surface with high precision requirements such as 7:24 internal and external tool cone surface and 1:12 bearing external cone surface are to be processed, such interpolation or plunge grinding method cannot meet the requirements Accuracy, roughness requirements
