Abstract
The invention discloses the adjustable valve processing unit (plant) of a kind of fixture, being driven by pneumatic means makes the distance between the first support and the second support regulate, before clamping valve, the spacing of the first support and the second support is strengthened, after valve to be processed is placed, regulate the distance between the first support and the second support, by jamming of valve; Because the distance between the first support and the second support can regulate, therefore can clamp different model valve.
Description
Technical field
The present invention relates to valve processing technique field, particularly relate to the adjustable valve processing unit (plant) of a kind of fixture.
Background technology
Valve is engine important composition parts, be responsible for input air in engine and get rid of the waste gas after burning, be divided into inlet valve and exhaust valve from structure, inlet valve is by air intake engine, burn with fuel mix, exhaust valve be by burning after waste gas discharge engine dispelling the heat.Classify from the finished product structure of valve, be usually 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 is higher due to operating temperature, needs heat-resisting alloy steel to make, in order to save cost exhaust valve head heat-resisting alloy steel, bar portion common alloy steel, so exhaust valve first operation is head bar and head butt welding.Specific process comprises: forging head, and head heating is burnt red, extruded; Machining, head turning be shaped, pole-footing portion cuts out draw-in groove; Heat treatment, increases case hardness; Grinding, the conical surface of head, the outer surface precision prescribed in bar portion is high, and grinding is to ensure to move in conduit and dispelled 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, by 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 and carry out the processing of car mill to arc surface afterwards, reach valve circular shape, precision and roughness requirements.
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., carrying out in above-mentioned processing procedure to valve, need to be fixed valve, some modes used in prior art otherwise be difficult to valve is fastening, cause in processing procedure and valve precision damaged, damage is caused to valve table wall, reduces product quality.And existing equipment can only be fixed the valve of single model, when needing to add the valve of different model just to need man-hour to change frock, cost is higher, and efficiency is lower.
Summary of the invention
In order to solve the technical problem existed in background technology, the present invention proposes the adjustable valve processing unit (plant) of a kind of fixture, to regulate the distance between the first support and the second support, adapting to clamping different model valve.
The adjustable valve processing unit (plant) of a kind of fixture that the present invention proposes, comprising:
Workbench;
First support and the second support, lay respectively at described workbench two ends, and the spacing of described first support and the second support is adjustable;
Chuck, being arranged in the rotating shaft of described first support, for blocking Valve Disc, under the driving of motor, driving valve to rotate;
Geometrical clamp, is arranged on described second support, for being rotationally connected engine valve stem top;
Knives rack, is arranged on the slide rail of described workbench by the second motor;
The base of tool, is arranged on described knives rack by the first motor, moves up and down under the driving of described first motor along described knives rack;
Cutter, is arranged on the described base of tool by rotary electric machine;
Numerical control unit, be electrically connected with described first motor, described second motor, described first pneumatic means and described second pneumatic means respectively, control described first support and described second support support distance to load and unload valve, and control described tool sharpening valve arc surface.
Preferably, described first Bracket setting, on the first slide rail, moves under the driving of the first pneumatic means.
Preferably, described second Bracket setting, on the second slide rail, moves under the driving of the second pneumatic means.
Preferably, described first support and described second support are separately positioned on the first slide rail and the second slide rail, move respectively under the driving of the first pneumatic means and the second pneumatic means.
In the present invention, driven by pneumatic means and the distance between the first support and the second support can be regulated, before clamping valve, the spacing of the first support and the second support is strengthened, after being placed by valve to be processed, regulate the distance between the first support and the second support, by jamming of valve; Because the distance between the first support and the second support can regulate, therefore can clamp different model valve.
