Description
Technical field
The present invention relates to a kind of Metal Cutting Machine Tool, more particularly to a kind of grinding machine tool of valve.
Background technology
Valve is the strength member on engine, and the quality of valve is to ensureing that it is most important that the operating efficiency of engine plays
Effect.In order to ensure the machining accuracy of valve, in laterostigmatal dish external diameter, discone antenna surface, umbrella, each surface such as large end face is will
By grinding come what is completed, the above-mentioned each surface of conventional valve grinding needs multiple working procedure to complete, so processing life
Produce inefficient, workpiece is needed by multiple clamping, be will also result in machining accuracy and is not easy to ensure, and in the valve of prior art
In grinding machine, by locating rod axially position, discharging generally is ejected valve to be ground after machining or by locating rod, is positioned
Bar is driven by the cylinder, and processed valve is clamped by collet, collet by clamping cylinder pull back and clamp
Effect, in the process, the clamping pulling force that locating rod can also be born by processed valve acts on so that locating rod has
The trend of displacement, the forfeiture of positioning precision is easily caused, influence the machining accuracy of valve；And in general, ground in valve
After the completion of cutting, valve is ejected by material ejection cylinder, drops on conveying body and transfers out, conventional conveying mechanism is flat
Belt conveyor, valve position not can determine that when conveying discharges, later process operation inconvenience.In addition, add to improve valve
The operating efficiency of work, it would be desirable to complete the grinding on above-mentioned each surface simultaneously by forming grinding wheel during clamped one time,
But in above-mentioned each surface one-shot forming Grinding Process of valve, grinding force can be very big, as grinding workpiece clamping point
Engine valve stem diameter it is thinner, it is impossible to bear the effect of grinding force, valve can produce flexural deformation in process, can not
Ensure machining accuracy, if reducing cutting data in order to reduce grinding force, production efficiency cannot be lifted, and also just be lost
The meaning of disposal molding processing.
The content of the invention
For the above-mentioned deficiency present in prior art, the technical problems to be solved by the invention be to provide it is a kind of once into
Shape valve grinder, it adapts to the requirement of the once-forming grinding of valve, and automaticity is high, and can guarantee that positioning precision,
Valve course of conveying after machining has defined location state.
In order to solve the above-mentioned technical problem, a kind of once-forming valve grinder of the invention, including lathe bed, rotating support exist
