Abstract
The invention discloses an air valve processing device with a separable chuck. The chuck is of a detachable structure, when an air valve disk bottom is clamped, the chuck is driven to be separated, after the air valve disk bottom is placed into the corresponding position, all parts of the chuck are driven to be closed, and the air valve disk bottom is clamped. Due to the fact that the chuck is of the detachable structure, disk bottoms with different diameters can be clamped, adaptability of the tool is improved, and equipment cost is reduced.
Description
Technical field
The present invention relates to valve processing technique field, relate in particular to a kind of valve processing unit (plant) with separable chuck.
Background technology
Valve is engine important composition parts, be responsible for to input air in engine and get rid of the waste gas after burning, from structure, being divided into inlet valve and exhaust valve, inlet valve is by air intake engine, with fuel mix burning, exhaust valve is that the waste gas after burning is discharged to engine heat radiation.From the finished product structure of valve, classify, be conventionally divided into whole valve, bimetallic butt welding valve and hollow sodium filling valve etc.Inlet valve adopts medium carbon alloy steel to make; Exhaust valve, because operating temperature is higher, needs heat-resisting alloy steel to make, and in order to save cost exhaust valve head heat-resisting alloy steel, the common steel alloy of bar portion, so exhaust valve the first operation is head bar and head butt welding.Specific process comprises: forge head, and head heating burning is red, extrusion modling; Machining, is shaped head turning, and pole-footing portion cuts out draw-in groove; Heat treatment, increases case hardness; Grinding, the conical surface of head, the outer surface precision prescribed of bar portion is high, and grinding is to guarantee in conduit motion and to dispel the heat by conduit; At the built-up welding of the exhaust valve conical surface or spraying tungsten-cobalt alloy, to increase hardness, wear-resisting, heat-resisting, rotproofness; With valve seating bedding-in.
Air valve structure as shown in Figure 1, comprises bar portion 1, dish portion 2, the dish conical surface 3 and arc surface 4, passes through the conical surface 3 and arc surface 4 transition between bar portion 1 and dish portion 2.At present, valve processing technology comprises: corase grind bar portion cylindrical, rough turn bar portion cylindrical, rough turn dish end face, location clamp carries out the processing of car mill afterwards to arc surface, reaches valve circular shape, precision and roughness requirement.
Very high to product requirement in reality processing, need to carry out a lot of PROCESS FOR TREATMENT to valve, such as cutting or grinding etc., valve is being carried out in above-mentioned processing procedure, need to be fixed valve, some modes of using in prior art or very difficult that valve is fastening, cause in processing procedure valve precision are damaged, valve table wall is caused to damage, reduce product quality.
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes a kind of valve processing unit (plant) with separable chuck, so that the valve on the big or small chassis of difference is clamped.
A kind of valve processing unit (plant) with separable chuck that the present invention proposes, comprising:
Workbench;
The first support and the second support, lay respectively at described workbench two ends;
Chuck, is arranged in the rotating shaft of described the first support, for blocking Valve Disc, drives valve to rotate under the driving of motor, and described chuck is split mechanism, comprises at least two parts, can separate and closure under the driving of functional unit;
Geometrical clamp, is arranged on described the second support, for being rotationally connected engine valve stem top;
Knives rack, is arranged on by the second motor on the slide rail of described workbench;
The base of tool, is arranged on described knives rack by the first motor, under the driving of described the first motor, along described knives rack, moves up and down;
Cutter, is arranged on the described base of tool by rotary electric machine;
Numerical control unit, is electrically connected to described the first motor, the second motor respectively, controls described tool sharpening arc surface.
Preferably, described numerical control unit is also electrically connected to the motor of drive shaft, to adjust valve rotating speed according to predefined parameter.
Preferably, the chuck edge of telling is provided with draw-in groove, for blocking valve retainer feather edge.
Preferably, described slide rail direction is consistent with valve axis direction.
In the present invention, for the chuck at the bottom of clamping valve retainer, be separable structure, in the time of at the bottom of clamping valve retainer, drive chuck is separated, will at the bottom of chuck disk, put into behind relevant position, and drive chuck each several part is closed, will at the bottom of valve retainer, block.Because chuck is separable structure, therefore, can different-diameter be tried to get to the heart of a matter and be clamped, improved the applicability of frock, reduced equipment cost.
