[0028] Working principle: When grinding a product with a special-shaped surface, first hold the handle set on one side of the second bidirectional threaded rod 9 and rotate it forward. The two clamping blocks 11 move toward each other along the outer surface of the slide bar 10 on the inner side of the fixed frame 8, clamp and fix the product with a large surface facing the second grinding wheel 5 and a small surface on the first grinding wheel 211. Hold the handle set on the front end face of the first bidirectional threaded rod 7 and rotate it forward. The first threaded block 202 and the second threaded block 6 respectively drive the first mounting frame 201 and the second mounting frame 3 to move toward each other. The first grinding wheel 211 and the second grinding wheel 5 are in contact with the small surface and the large surface of the special-shaped product respectively. The first motor 203 and the second motor 4 are started in a step. The output end of the second motor 4 drives the second grinding wheel 5 to grind the large surface of the special-shaped surface product. The output end of the first motor 203 drives the driving gear 205 to mesh and rotate with the driven gear 212. The driving gear 205 has a smaller cross-section than the driven gear 212, which plays a role in frequency conversion and frequency modulation and deceleration of the motor.

At the same time, the first grinding wheel 211 is driven to rotate the small surface of the special-shaped surface product, so that the rotation speed of the first grinding wheel 211 is slower than that of the first grinding wheel 5, so as to avoid that the two grinding wheels have different grinding amounts on the special-shaped surface product at the same rotation speed, which affects the processing quality. By setting two sets of motors to drive the two grinding wheels respectively, the front and back large and small surfaces of the special-shaped surface product are ground simultaneously. For the small surface of the special-shaped surface product, when the driving gear 205 with a smaller cross-section drives the driven gear 212 with a larger cross-section, the rotation speed of the first motor 203 is controlled, so as to reduce the friction of the second grinding wheel 211 on the small surface of the special-shaped surface product, so that the special-shaped surface product The grinding amount of the two surfaces is the same, achieving the effect of a vertical grinder, reducing the processing time of special-shaped surface products, and improving the processing efficiency of special-shaped surface products. When the first threaded block 202 and the second threaded block 6 move toward or oppositely, they slide with the inner wall of the support frame 1, playing a limiting role to prevent the positions of the two grinding wheels from shifting. By arranging a guard plate 213 on the outer surface of the mounting plate 206, the guard plate 213 is located above the driving gear 205 and the driven gear 212, which plays a protective role to prevent people from accidentally touching the meshing gear set, causing injuries to people, thereby improving the protection effect of the variable frequency modulation grinding equipment for special-shaped surface products.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
