[0011] A method for setting the tool of a vertical inclined grinding wheel for rail profile includes the tool setting process as follows:

[0012] S1. Angle conversion: There are two angles, namely the grinding wheel deflection angle and the grinding wheel swing angle, for the rotation axis of the grinding wheel of the vertical inclined grinding. These two angle values are determined by the grinding process. The grinding wheel deflection angle is the angle between the projection of the rotation axis of the grinding wheel on the XOY plane of the device coordinate system and the X axis of the device coordinate system. The grinding wheel swing angle is the angle between the rotation axis of the grinding wheel and the XOY plane of the device coordinate system. The device has two angles, namely the device deflection angle and the device swing angle. The angle between the plane where the upper plane of the support plate (202) is located and the XOZ plane of the device coordinate system is the device deflection angle. The angle between the plane where the movable angle of the support plate (202) is located and the XOY plane of the device coordinate system is the device swing angle. There is a certain conversion relationship between the device deflection angle and the device swing angle of the device and the grinding wheel deflection angle and the grinding wheel swing angle of the grinding wheel. Specifically: Based on the device coordinate system, if the grinding wheel deflection angle is α1, the grinding wheel swing angle is β1, the device deflection angle is α2, and the device swing angle is β2, then through trigonometric coordinate conversion, we can get: sinα1cosβ1 = sinα2, cosα2sinβ2 = sinβ1. By calculation, the device deflection angle α2 and the device swing angle β2 can be obtained under the condition that the grinding wheel deflection angle α1 and the grinding wheel swing angle β1 are determined.

[0013] S2. Coarse adjustment of the device position: Loosen the compression knob (103), which drives the threaded rod (102) to rotate, and then the compression roller (101) retreats along the axis of the threaded rod (102), thereby canceling the compression effect of the device. Move the tool setting device along the axial direction of the rail. When moving until the grinding wheel feed can contact the tool setting disc (301), stop and tighten the compression knob (103) to complete the fixation of the device.

[0014] S3. Adjustment of the device swing angle: Loosen the bolts connecting the connecting piece (201) and the base (106). According to the device swing angle calculated in the previous step, change the position and orientation of the connecting piece (201) on the base (106) so that the angle between the side plane of the connecting piece (201) and the XOY plane of the device coordinate system is equal to the calculated device swing angle. After reaching the required device swing angle, tighten the bolts connecting the connecting piece (201) and the base (106).

[0015] S4. Adjustment of the device deflection angle: Loosen the disc locking bolt (209). According to the device deflection angle calculated in the previous step, rotate the lifting knob (206) to change the lifting height of the lifting member (208), and then change the moving angle of the support plate (202) so that the angle between the plane where the upper plane of the support plate (202) is located and the XOZ plane of the device coordinate system is equal to the calculated device deflection angle. After reaching the required device deflection angle, tighten the disc locking bolt (209).

[0016] S5. Fine adjustment of the device position and tool setting: Loosen the pressing knob (103) to cancel the pressing effect of the device. Slowly move the tool setting device along the axial direction of the rail, and at the same time change the spatial position of the grinding wheel so that the two end faces of the grinding wheel are aligned with the two sides of the rectangular notch at the top of the tool setting disc (301). When the measuring head of the dial indicator (303) contacts the grinding wheel and produces a slight compression, keep the spatial position state of the grinding wheel unchanged at this time. Slowly move the tool setting device. When the measuring head of the dial indicator (303) is compressed to the maximum position, tighten the pressing knob (103) to fix the device position. Manually rotate the grinding wheel, and the compression position of the measuring head of the dial indicator (303) remains unchanged.

[0017] The lifting member (208) and the gear (205) adopt a small-module gear-rack matching form. By manually rotating the lifting knob (206), the lifting height of the lifting member (208) can be finely adjusted to achieve precise adjustment of the device deflection angle.

[0018] The positioning and movement of the device on the rail are both realized through the positioning rollers (104). The rail contacts the 4 positioning rollers (104) to meet the positioning requirements of the actual device, and at the same time, it is also convenient to move the base (106) along the Z-axis direction of the device coordinate system.
