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
The invention belongs to the valve production equipment, especially for the special equipment that cuts off valve stem.
Background technology
Engine valve is one of vital part of engine, and engine is automobile " heart ", and valve is " valve " of engine.Engine valve is worked under very harsh environment, high-speed motion under the environment impacted at high temperature, burn into, and, working environment changes along with the variation of outside operating mode, and such environment, for valve, except selection rationally, the required precision of valve is high especially.Valve and piston interference problem, do not appear simultaneously in the demand of opening for meeting timing, and the length direction of valve must strictly be controlled.
In the processing technology of valve, the control of valve length direction is extremely important, is also difficult point.Overall length is after the cumulative errors of blanking, electric upsetting, the operation such as molded, more than the overall length error has several millimeters at least, so generally all will adopt the cut-out operation after moulding, processing mode before is all that workpiece is fixed on the V-type frame, valve does not rotate, and allows the grinding wheel of rotation cut off the valve mode.This kind of mode has following some shortcoming:
1, the valve low precision processed: exist for a long time the overall length scattered error to have greatly always be greater than 0.3, the bad phenomenon such as end face run-out scattered error large (what have is greater than 0.2), section burr.
2 and cutoff wheel thickness thick, the material cut away is many, the utilization rate of material is low;
3, the life-span of grinding wheel low, generally each class needs to change, and affects efficiency.
4, because the grinding wheel life-span is low, average cutter expense to every workpiece is high.
5,, in order to improve quality, make up the deficiency of precision through the way that increases operation commonly used.
Summary of the invention
In order to overcome the poor deficiency of existing valve end cutting equipment machining accuracy, the invention provides a kind of valve end cutting machine, this valve end cutting machine adopts and under the state that drives valve rotation, uses the CBN grinding wheel of High Rotation Speed to carry out the valve end cutting.
The technical solution adopted for the present invention to solve the technical problems is: a kind of valve end cutting machine is characterized in that: comprise valve rotation drive unit, valve positioner and valve end cutter sweep,
Described valve rotation drive unit is comprised of with the pinch roller that is positioned at the valve stem top two rollers with the synchronous rotary in the same way of rotating driving device that are parallel to each other that are positioned at the valve stem below,
Described valve positioner is comprised of the rotatable backstay that is positioned at the valve retainer outside and the movable positioning head of disc that is arranged on the backstay front end,
Described valve end cutter sweep is the CBN grinding wheel with the High Rotation Speed of feed system.
The structure of described roller is that roller core bar two ends are equipped with two isodiametric circular wheel.
The rotating driving device of described valve rotation drive unit is by the motor that is fixed on plant bottom case and be arranged on motor gear on motor shaft and form with its engagement the roller tooth wheel that is arranged on roller shaft.
In technique scheme, do not have in the present invention rotary actuation, the feed arrangement of CBN grinding wheel in the installation, valve end cutter sweep of installation site design parameter, the valve positioner of the valve rotation drive unit that describes in detail all to adopt correlation technology of the prior art.
Using in the present invention by motor-driven two rollers and pinch roller valve rotation drive unit makes valve coordinate the high-speed cutting of CBN grinding wheel in rotation, greatly reduce end face run-out, can improve the end face precision, (the overall length scattered error is less than 0.1, end face run-out is less than 0.03) because CBN can keep the sharpness of the micro-sword of abrasive particle for a long time, can make workpiece to be machined obtain high dimensional accuracy and low surface roughness, finished surface is difficult for cracking and burning, and residual stress is little.Machined surface quality is improved, and general flawless, be difficult for burn, and can obtain residual compressive stress, significantly improves workpiece fatigue strength, and usually, the durability of grinding workpiece can improve 30-50%.Adopt in addition the CBN emery wheel, because well often changing a grinding wheel, its anti-wear performance can cut 60000 valves, save the time of changing cutter and improved operating efficiency, and need end grinding and chamfering two procedures after having saved original cutting, save manpower and equipment, through every valve processing cost of comprehensively measuring and calculating, reduced by 0.5 yuan.
The invention has the beneficial effects as follows: the improving product machining accuracy.There is no machined burrs, greatly reduce end face run-out.Can reduce follow-up cross grinding and rod end chamfering process simultaneously.
