Surely being set with one end and be provided with the knob mandrel 24 of pin 23, pin 23 docks with the open slot of spool 22, supports
Seat 26 and boss thereon dock with the counterbore of valve body 21 right side, pressure head 20 and the left side card of switch valve
Connect and switch valve is clamped, anti-rotation baffle plate 43 limit switch valve position of rotation, carry out switch valve location, drive
Dynamic motor 34 is other is provided with aobvious control man-machine interface 32, can be adjusted abrasive parameters, revise.
The Ginding process of gas stove switch valve grinding machine, concrete grinding steps is as follows:
(1) switching on power, press start button 5, grinder is in holding state；Spool and valve body are coated with
Smear grinding agent assembling of matching；
(2) switch valve location.Pin 23, knob mandrel 24 and spool 22 open slot realize determining of spool 22
Position.Support seat 26 and boss thereon, with the location that valve body 21 right side counterbore realizes valve body 21.Due to
Switch valve profile is irregular, and used by clamping, the time is short, after switch valve is placed on working position, when single pole cylinder
15 startups clamp to the right, it is difficult to ensure that be accurately positioned.Now variable-speed motor 34 starts, and drives motor
The main shaft of 34 drives switch valve to rotate, and rolling bearing 19 and rolling bearing 28 guarantee that valve body 21 is electronic with driving
The main shaft of machine 34 rotates, when the mounting ear of processed valve body 21 encounters anti-rotation baffle plate 43, and valve body 21 i.e. stops
Rotate and complete location.Pin 23 then continues to rotate, until rotating to spool 22 under knob mandrel 24 drives
Open slot at, spring 41 act under, pin 23 is pushed in open slot, it is achieved the location of spool 22.

Right side, forms right clamp body, and gas pressure, in single-rod cylinder 15, completes switch valve clamping.Clamping cylinder
Movement velocity can be set up by the flow speed control valve (being not drawn in figure) in atmospheric control, clamping pressure by
Pressure-reducing valve (parts in atmospheric control, be not drawn in figure) is set up, and clamping cylinder time sequencing passes through PLC
Instruction is given.
(4) grinding main motion, spool 22 is the relative motion by two parts with the pairing grinding of valve body 21
Realize.The variable-speed motor driving motor 34 to use band gearhead to slow down, is fixed on by bolt 36
On support plate 35, variable-speed motor output shaft is supported by thrust ball bearing 33, and power is through variable-speed motor axle
Neck and flat key 38 are delivered to Hollow Transmission Shafts 40, then through this axle left end symmetry groove, two pairs of top fastening bolts 42 pass
To power transmission shaft 25.By holding screw 30, knob mandrel 24 is formed removable connection with power transmission shaft 25, adjust
The power of the electric motor with speed pin 23 through knob mandrel 24 left part is delivered to workpiece spool 22 to be ground, is allowed to
Rotate together with the main shaft of variable-speed motor, form the main motion ground.
Two pairs of top fastening bolts 42 can do the skew of certain angle in symmetrical channels, it is ensured that spool 22 and valve body 21
Centering in process of lapping.
(5) grind feed motion, grind feed motion and realized by double-rod cylinder 9, use double-rod cylinder 9
Purpose be to ensure that the straight line stability of feeding.Double-rod cylinder 9 is fixed on workbench 8 by bolt 10,
Form entirety with machine to be fixedly connected.Support plate 14 and support plate 31 are fixed on planker 12 by bolt 13,
Through bolt 11, planker 12 is fixed on the piston rod two ends of double-rod cylinder 9, moves left and right together with piston rod,
Realizing feed motion, feed speed passes through choke valve (parts in atmospheric control, be not drawn in figure)
Adjustable, the feeding time is by PLC control.
(6) light grinding and heavy cutting, when workpiece positioning and clamping puts in place, under variable-speed motor drives, spool
22 and valve body 21 i.e. initially enter the light grinding stage.After the time delay several seconds, double-rod cylinder 9 is started working, planker
12 start to move right, and under the effect of spring 41, the dynamics that contacts between spool 22 with valve body 21 is gradually
Increase, i.e. enter the heavy cutting stage.Gently, heavy cutting carry out stage by stage, each section of milling time is by aobvious control people
Machine interface input parameter is modified adjustment, has ground when meeting the characteristic requirements of grinding to switch valve.
Electric control system 7 uses PLC system control, and PLC chip uses Panasonic's Programmable Logic Controller
AFPXO-L30R, aobvious control man-machine interface 32 uses SK-035AE.PLC system controls workflow diagram such as
Shown in Fig. 6.
Being illustrated in figure 5 the structured flowchart of electric control system 7, it has a following feature:
(1) realize high-low voltage and separate layout.
Driving motor to use 220 volts of exchanges to drive, its governing system and speed show individually to be set up, PLC
Only controlling the startup time, other elements are 24 volts of direct current component, are provided with an independent 24V dc source, letter
Changing electric-control system, all ECUs concentrate in control box, it is simple to operate with and safeguard.Electric cabinet is pressed
IP54 grade designs, it is ensured that security performance.
(2) realize individually controlling between station.
Four station unifications are by PLC control, but can control by independent operating.The clamping cylinder of four stations and entering
To operating pressure and the flow of cylinder, unification is controlled by pressure-reducing valve and throttle setting.The speed of mainshaft and processing
Time all can be separately provided and adjust, and has both adapted to the differentiation requirement of each station, can ensure that again a certain
The normal work of other stations is not affected when station breaks down.
(3) timing monitoring and amendment are realized.
The various signals gathered are focused on by PLC, the control signal of output correspondence and alarm signal,
Aobvious control man-machine interface is kept in communication with PLC.Display screen presses four station Pagination Display duties and parameter,
And accept amendment and the preservation of data.
(4) the most adjustable of grinding temperature is realized.
Grinding and easily form high temperature, affect workpiece quality, the control of temperature is mainly by controlling milling time
Realize with arranging circulation.Adjusted by the speed of time interval and double-rod cylinder, the heat radiation time can be adjusted to
Optimum value.Smear grinding agent before spool and valve body pairing, also function to certain thermolysis.
Important technological parameters is as follows:
The beneficial effects of the present invention is:
(1) use PLC system to control and show control man-machine interface, facilitating parameter adjustment and system to control, reduce
Grinding technique difficulty；
(2) be combined with pneumatic control by electrical control, grinding is divided into light grinding the heavy cutting stage, time
Between and dynamics easy to control accurately, improve product processing quality.
