Abstract

The invention discloses an abrasive belt polishing device, which comprises an engine base, a transmission device and a tailstock device which are arranged on the engine base, an electromotor, an abrasive belt rack device, a winding device and a polishing rack device, wherein the transmission device and the tailstock device are provided with ejector pins arranged oppositely and used for clamping a workpiece; the electromotor is arranged on the engine base and is used for driving the ejector pins on the transmission device to rotate; the abrasive belt rack device is arranged on the engine base and is used for winding an abrasive belt; the winding device is arranged on the engine base and can be used for automatically winding the abrasive belt which exceeds a preset length after a one-time polishing process; and the polishing rack device is arranged on the engine base and is used for compressing the abrasive belt to a polishing face of the workpiece. According to the abrasive belt polishing device, the surface roughness of the cam workpiece reaches below Rz3.2, the chatter marks and the closed angles on the surface of the workpiece are eliminated, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of automobile engine parts, in particular to an abrasive belt polishing device. Background technique [0002] The camshaft is a component in a piston engine that controls the opening and closing of the valves. Although the speed of the camshaft in a four-stroke engine is half that of the crankshaft (the speed of the camshaft is the same as that of the crankshaft in a two-stroke engine), it is usually still high in speed and needs to withstand a lot of torque, so the design of The camshaft has high requirements in terms of strength and support, and its material is generally special cast iron, and occasionally forgings are also used. Since the valve movement law is related to the power and running characteristics of an engine, the accuracy of the camshaft plays a very important role in the design process of the engine. [0003] After the cam surface is ground, there is usually no surface physical treatment, ...
