Abstract

The invention discloses an end part cutter for a valve rod, and belongs to valve production equipment, in particular to equipment special for cutting the valve rod. The end part cutter for the valve rod is characterized by comprising a valve rotating driving device, a valve positioning device and a valve rod end part cutting device, wherein the valve rotating driving device consists of two parallel rollers and a pressure roller positioned above the valve rod, and the two rollers are positioned below the valve rod, are provided with rotating driving devices, and synchronously rotate in the same direction; the valve positioning device consists of a rotating positioning rod positioned outside a valve retainer and a disc-shaped movable positioning head arranged at the front end of the positioning rod; the valve rod end part cutting device is a high-speed rotating CBN (cubic boron nitride) grinding wheel with a feeding system. The end part cutter has the beneficial effects that the machining accuracy of a product is improved; machining burrs are avoided, and end face run-out is greatly reduced; in addition, subsequent end face grinding and rod end chamfering procedures can be reduced.

Description

technical field [0001] The invention belongs to valve production equipment, in particular to special equipment for cutting off valve stems. Background technique [0002] The engine valve is one of the key parts of the engine, the engine is the "heart" of the car, and the valve is the "valve" of the engine. Engine valves work in a very harsh environment and move at high speed in high temperature, corrosion, and impact environments. Moreover, the working environment changes with changes in external working conditions. In such an environment, for the valve, in addition to reasonable material selection, The accuracy requirements of the valve are particularly high. In order to meet the demand of timing opening and avoid the interference between the valve and the piston, the length direction of the valve must be strictly controlled. [0003] In the processing technology of the valve, the control of the length direction of the valve is very important and difficult. After the cum...
