Milling device for case fans

Abstract

The invention provides a milling device for case fans. The milling device comprises a base. The base is provided with a milling mechanism, a transmission mechanism and a control mechanism. The transmission mechanism is connected with the base in a rotating manner. The transmission mechanism is provided with a plurality of stations. The milling mechanism is provided with a plurality of milling cutters. The cutters correspond to the stations. The milling cutters are located above the transmission mechanism. The milling cutters can move and ascend or descend on the milling mechanism. The controlmechanism is located on the transmission mechanism. The control mechanism is in fitting connection with the transmission mechanism. Compared with the prior art, under the effect of two sliding rails and one lifting part, the milling cutters can move in an all-dimensional manner, and therefore in the operation process, the milling cutters can carry out milling more precisely. Meanwhile, under the effect of the pressing parts, the case fans are fixed to a rotating disc, location of the pressing parts will not abrade the case fans, automatic transmission of the case fans is achieved, the millingcutters mill the two case fans at the same time, and therefore the working efficiency is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of case fan processing, and in particular relates to a milling device for a case fan. Background technique [0002] Computer fans, also known as cooling fans, are generally used for heat dissipation of computer hosts. Computer fans are mainly divided into motherboard cooling fans and chassis cooling fans. Common cooling fans on the market range in size from 2.5cm to 30cm in diameter and from 6mm to 76mm in thickness. According to different operating requirements, rare AC ( AC, powered by household sockets) and common D power supply (DC, powered by computer fire or motherboard), most of them use two-phase motors (two sets of copper coils, a total of four units), there are Conducive to saving production costs. [0003] The chassis fan is used for heat dissipation of the chassis. When the chassis fan is in use, it can discharge hot air along the rear panel of the chassis, so that cold air can flow into the ch...

AI Technical Summary

Problems solved by technology

[0004] In the production of chassis fans, because the material of chassis fans is usually plastic, in the production of chassis fans, when plasticizing the chassis fan casing, a large number of burrs will be generated at the connection of the chassis fan casing, and the burrs are mainly distributed in the chassis. The burrs on the surface of the fan and its connection, the surface of the chassis fan will affect the stability of the chassis fan when it is assembled with the chassis, so that when the chassis fan is installed on the chassis, it cannot be completely attached to the chassis, thus affecting the positioning of the chassis fan on the chassis , which in turn affects the heat dissipation of the chassis. At the same time, the burrs at the connection of the chassis fan will have a certain impact on the fan blades, which will affect the normal rotation of the fan blades, cause the fan blades to block during the rotation process or cause damage to the fan blades, thus affecting the chassis. The heat dissipation is not conducive to the heat removal of the chassis

[0005] In the prior art, milling cutters are usually used to process the burrs of the chassis fans, and the rotating cutters with one or more teeth of the milling cutter are used to intermittently cut off the burrs of the chassis fans successively; and during the milling process of the chassis fans , because the molding material of the chassis fan is relatively soft, this requires higher requirements for the milling process of the milling cutter. The operation of the chassis fan is difficult, and the positioning of the chassis fan is complicated. When the chassis fan is positioned and removed, it may cause wear and tear on the chassis fan, thus affecting the aesthetics of the chassis fan
