Abstract

The invention discloses an active-driving grinding device, which comprises a trimming ring, a base disc and a grinding disc and also comprises a driving motor, an output gear, three stressed gears and an auxiliary gear that can rotate freely, wherein the driving motor is arranged on a base, the output gear is connected with the driving motor and is meshed with the stressed gear, the stressed gear is fixedly connected with the trimming ring by a bolt, the trimming ring is fixed on the grinding disc by a trimming ring fixing part and can rotate around a fixed center line, the base disc is clamped in the trimming ring, a screw hole is arranged in the grinding disc, the auxiliary gear is positioned in the centers of the three stress gears and is meshed with the stressed gears, and the lower parts of the auxiliary gear is fixed on the grinding disc through the screw hole. According to the device, the machining efficiency and the machining quality are improved; meanwhile, the rotation speed of the motor can be regulated, and the machining efficiency can be flexibly regulated, and therefore, the device is a novel driving mechanism with high grinding accuracy and low cost.

Description

technical field [0001] The invention belongs to the field of grinding devices, and in particular relates to an active driving grinding device. Background technique [0002] There are many kinds of grinding machines at home and abroad, mainly including double shaft type, linear type, swing type and online dressing type. The processing method of online dressing is that the dressing ring relies on the relative movement with the base plate to generate frictional force to rotate, thereby driving the workpiece to move, which is a non-active driving mechanism. [0003] It is generally considered that when the workpiece speed ω w and grinding disc speed ω p equal, that is, ω w =ω p The uniformity of material removal on the machined surface is the best. The reason is that the material removal rate RR at a point on the machined surface of the workpiece is proportional to the machining load P and the relative velocity V according to the Preston equation RR=kPV. when ω w =ω p Wh...
