Embodiment Construction

[0021] Below, refer to Figure 1- image 3 , the first embodiment of the dressing device according to the present invention will be described. FIG. 1 is a plan view showing the overall configuration of a cylindrical grinder including a dressing device according to the first embodiment. figure 2It is an enlarged sectional view along line 2-2 in Fig. 1. As shown in Figure 1, the processing part table 11 that is guided and supported by the grinding machine table 10 of the cylindrical grinder and can move along the horizontal left and right direction (Z direction) is driven by the Z-axis motor 18 to reciprocate. 11 is fixed opposite to the Z direction: the main shaft seat 12 bearing the main shaft 13 having a rotation axis parallel to the Z direction, and the tailstock that supports the top sleeve 15 coaxially arranged with the main shaft 13 and enables it to advance and retreat Seat 14. Both ends of the machining member W (the crankshaft of the internal combustion engine in the...

Abstract

A wheel truing apparatus adapted for use in a cylindrical grinding machine wherein a work head with a work spindle for support of a workpiece and a wheel head with a grinding wheel for grinding the workpiece are mounted on a bed for relative movement in a Z-axis direction parallel with the rotation axis of the work spindle and in an X-axis direction crossing the Z-axis direction, characterized in that the wheel truing apparatus comprises a rotary drive portion mounted on the work head or a member united therewith, and a wheel truing tool supported on the rotary drive portion for rotation therewith, the wheel truing tool being provided at its outer periphery with a truing portion for truing a grinding surface of the wheel brought into contact therewith, wherein the rotary drive portion is placed in a position adjacent to said work head in a tooling area defined by a stroke of the relative movements of said wheel head and said work head in the Z-axis direction and apart from said work spindle radially outward and is arranged in such a manner that the rotation axis line of said truing tool is oriented toward the rotation axis line of said grinding wheel in a condition where said truing portion is retained in contact with the grinding surface of said wheel, whereby the truing portion of said tool is brought into contact with the grinding surface of said wheel by relative movement of said wheel head to said work head for truing the grinding surface.

Description

technical field [0001] The present invention relates to a grinding wheel dressing device which abuts on the grinding surface of a grinding wheel of a cylindrical grinder and dresses it. Background technique [0002] When the grinding wheel of the cylindrical grinder grinds the processed parts, the shape of the grinding surface will be deformed, resulting in a decrease in processing accuracy, or the sharpness will decrease due to the rounding of the tip of the abrasive grains, so in order to restore its ability, it is necessary to dress the grinding wheel. This grinding wheel dressing includes shaping dressing to correct the grinding surface to a correct shape, and grain dressing to round the tip, break the abrasive grains, regenerate the tip, and restore the sharpness. [0003] In general, a cylindrical grinder is provided with a spindle base that supports a spindle that supports and rotates a workpiece, and a grinding wheel base that supports and rotates a grinding wheel t...
