Embodiment Construction
[0033] The present invention will be further described below in conjunction with accompanying drawing:
[0034] Such as Figure 1~4 As shown, a polishing roller with a parabolic groove for a linear hydraulic pressure polishing device includes a cylindrical body with a diameter of 40mm and a length of 350mm, and the surface of the cylindrical body is engraved with at least eight tracks along its radial direction. Parabolic grooves are evenly distributed, and a fixed-length interval is set between adjacent parabolic grooves.
[0035] The cylindrical body is made of aluminum alloy.
[0036]The parabolic groove includes two groove sides, wherein one groove side is parabolic, the other groove side is linear and the extension line of the groove side passes through the axis line of the cylindrical body; The number of parabolic grooves is 10-20, and the optimum number is 12.
[0037] The linear groove side length of the parabolic groove is 0.5-3mm, and the optimal length of the str...

The invention discloses a polishing roller provided with parabola-shaped grooves and used for a linear hydraulic pressure polishing device. The polishing roller comprises a cylinder body with the diameter being 40 mm and the length being 350 mm; the at least eight evenly-distributed parabola-shaped grooves are carved in the surface of the cylinder body in the radial direction; and an interval of afixed length is arranged between the adjacent parabola-shaped grooves. hydraulic pressure with linear and even distribution can be formed between the polishing roller and a polished workpiece of thelinear hydraulic pressure polishing device, and ripples on the surface of the workpiece can be eliminated only by reasonably controlling the feeding movement of the polishing roller; and the parabola-shaped grooves are designed uniquely on the surface of the polishing roller at equal intervals to form the structured surface, the hydraulic pressure effect is enhanced, and accordingly the machiningefficiency and quality of the polished workpiece are improved.
Description
technical field [0001] The invention relates to the field of polishing, and more specifically relates to a polishing roller with parabolic grooves used in a linear hydraulic pressure polishing device. Background technique [0002] Studies by domestic and foreign scholars have shown that the hydrodynamic pressure during polishing is beneficial to the removal of workpiece surface materials, but the hydrodynamic pressure formed by the relative movement between the polishing tool and the workpiece during hydrodynamic polishing generally has insufficient pressure and unevenness. phenomenon, resulting in a longer time required for hydraulic polishing. [0003] The traditional hydraulic polishing device usually uses a disc-shaped polishing workpiece carrier. This disc-shaped polishing carrier has some design defects. For example, because the workpiece is mounted along the radial direction of the carrier, the When rotating, the linear speed of each part of the workpiece is differen...
