Two-sided automatic polishing machine

Abstract

The invention discloses a two-sided automatic polishing machine, which comprises a horizontally arranged rotary table, an outer box, an upper abrasive wheel and a lower abrasive wheel, wherein the rotary table is provided with at least two through holes which are station holes; distances from the station holes to the center of the rotary table are the same; each station hole is used for transmitting a processing workpiece; the outer box is used for accommodating the rotary plate and is provided with an upwards opening; a through hole is arranged in a bottom face of the outer box; the upper abrasive wheel and the lower abrasive wheel are respectively arranged above and below the rotary plate and are horizontally arranged; rotating directions of the upper abrasive wheel and the lower abrasive wheel are opposite; the upper abrasive wheel can be lifted up and down, the lower abrasive wheel penetrates through the through hole of the outer box when being used for polishing, so that the upper surface of the lower abrasive wheel and a base plate of the rotary plate are coplanar; and wheel faces of the upper abrasive wheel and the lower abrasive wheel pass through the station holes in the middle parts of the upper abrasive wheel and the lower abrasive wheel when being rotated after stretching into the rotary plate. The two-sided automatic polishing machine has the beneficial effects that a table board of a radiator can be efficiently polished, the production efficiency is high, and the problems that the production efficiency for the table board of the radiator is low, the product quality is instable, and the market competitiveness is weak are solved.

Description

technical field [0001] The invention relates to a double-sided automatic polishing machine, which is mainly used in the technical field of heat sink table top processing. Background technique [0002] Water-cooled radiators for high-power power semiconductor devices are mainly copper-body water-cooled radiators. Due to the high manufacturing cost, it is generally cast by adding an appropriate proportion of alloy aluminum (aluminum-manganese) to pure aluminum in the world. It is a water-cooled radiator with an aluminum alloy body. The surface of the aluminum alloy cast radiator is relatively rough. The water-cooled radiator for high-power power semiconductor devices not only requires a high double-surface high-precision surface of the radiator, but also requires a high The parallelism of the workpiece surface. When used in high-voltage, high-power, DC transmission and other devices, it can be used for more than a dozen or dozens of water-cooled heat dissipation devices conne...
