Problems solved by technology

[0005] 1) The shape accuracy of the surface of the sidewall plate formed by CNC lathe turning is low. When the surface roughness is reduced by manual grinding and polishing of the surface, the original shape accuracy of the surface CNC turning is destroyed to a certain extent, which ultimately affects radial tire products. stiffness and eccentricity;
[0006] 2) The processing surface accuracy of the sidewall molding surface cannot meet the high requirements. Manual grinding and polishing of such a large-area surface has low processing efficiency and unstable quality. The surface can only be smooth, which affects the smoothness and smoothness of radial tire products. Eccentricity

Embodiment 1

[0035]The present invention is used for the processing of the workpiece 1 having the curved surface of revolution as the axisymmetric molding surface of the side plate of the radial tire active mold. The processing device is shown in Figures 2 and 3, which includes an arc-shaped grinding wheel 2, a workpiece rotary drive spindle 3, Grinding wheel rotation drive spindle 4, A-axis servo motor 7 perpendicular to / parallel to the workpiece rotation drive spindle, B-axis servo motor 8 perpendicular to A axis, A-axis table 9, B-axis table 10, The two-axis linkage numerical control device 11, the grinding wheel rotary spindle mounting base 18, the grinding machine bed 21, the workpiece 1 with the rotary curved surface is clamped on the rotary drive spindle 3 for rotary feed movement, and the arc-shaped grinding wheel 2 is installed on the high-speed rotation The shaft end of the grinding wheel rotary driving main shaft 4, the grinding wheel rotary driving main shaft 4 is installed on t...

Embodiment 2

[0045] The present invention is used to process the workpiece 1 having an axisymmetric convex surface shape, its structure is shown in Figure 8, its grinding process and grinding wheel dressing process are the same as in Embodiment 1, only need to appropriately change the numerical control processing program, then Grinding of workpieces with axisymmetric convex surfaces can be realized.

Embodiment 3

[0047] The present invention is used to process the workpiece 1 with a combined shape of axisymmetric convex-concave surface. Its structure is shown in Figure 9. When the grinding wheel 2 is used, the installation structure of embodiment 1 or embodiment 2 will produce collision and interference between the grinding wheel rotary drive spindle 4 and the workpiece 1. For this reason, the axes of the arc-shaped grinding wheel 2 and the grinding wheel rotary drive spindle 4 must be inclined at a certain angle. The rotary table 13 of the grinding wheel dressing tool is inclined at the same angle in the same direction at the same time, so that the workpiece with an axisymmetric convex-concave composite surface or a relatively deep axisymmetric concave curved surface can be ground. same.
