The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, double face abrading machine comprises emery wheel mechanism, Workpiece transfer mechanism, automatic feed mechanism.
Emery wheel mechanism comprises main shaft 3,4 and is separately fixed at emery wheel 1,2 on the main shaft 3,4, main shaft 3,4 is on same axial line, emery wheel 1 and emery wheel 2 rotate alone and stepless speed regulation, two main shafts 3,4 independently are provided with tilt adjustments and axis guiding mechanism, and guiding mechanism can be adjusted emery wheel inclination angle and axial trickle, fast feed.
Two emery wheels are provided with trim locations and correcting compensation amount, when trimming wheel, can enter trim locations fast, and trim amount compensates automatically, and the home position is constant when entering grinding again.
Described Workpiece transfer mechanism comprises the travel mechanism of workpiece fixture and workpiece fixture, the workpiece fixture divides two parts up and down, the lower part is called workpiece clamp 6, it is provided with the groove 61 that workpiece is installed, and the mechanism 62 of locking workpiece is set on groove 61 limits, and see Fig. 3, adopt piston rod 62 in the present embodiment, and link to each other with hydraulic system by oil pipe 63, see Fig. 2.Workpiece clamp 6 is fixing with linking arm 64, linking arm 64 or with workbench 9 one or be fixed on the workbench 9; For pushing down the unsteady pressure head 8 of workpiece when falling, the pressure head 8 that floats is connected with support arm 7 accordingly on top, and support arm 7 middle part axles are connected on the workbench 9, and its other end 71 is connected with hoist cylinder 20 piston rods, sees Fig. 2; Workbench 9 is fixed with the piston rod of the mobile oil cylinder 14 of push work platform, the moving direction of workbench vertical with the spindle centerline of emery wheel and with the work piece holder work perpendicular to moving back and forth between two emery wheels;
Look the thickness of workpiece 5 in the workpiece groove 61 and can put into a plurality of workpiece 5.After workpiece 5 put in place, the pressure head 8 that floats pressed down the dynamic head 8 of floating downward in the promotion of hoist cylinder 20 and fixes each workpiece 5 respectively, but therefore each a plurality of workpiece of grinding.
The structure of unsteady pressure head 8 is seen Fig. 4, Fig. 5, and its head is an elasticity dog 81, and elasticity dog 81 is arranged by spaced annulus 82 and formed the head band breach 821 of annulus 82 and workpiece 5 contact portions.Each annulus 82 of its elasticity dog 81 was just pushed down the workpiece 5 in the workpiece clamp 6 and is made workpiece 5 spacing when the pressure head 8 that floats was depressed, and can not move when grinding.Because annulus head band breach 821, the fixing of pressure head and workpiece of therefore floating is still flexible, and workpiece 5 is stressed more even, can not damage workpiece 5.
Be smooth push work platform 9, workbench can be provided with guide rail 91 9 times.
The workpiece automatic feed mechanism comprises pedestal 10, expeller 11, pushing piston bar 12, goes up material oil cylinder 13, spacing adjustment piece 15, see Fig. 1, expeller 11 is fixed on the pushing piston bar 12, and with the groove 61 of workpiece clamp 6 on same straight line, last material oil cylinder 13 is fixed on the pedestal 10, spacing adjustment piece 15 links to each other at the opposite side of workpiece clamp and with trigger, and trigger links to each other with control program.Spacing adjustment piece 15 restriction workpiece 5 enter the position of grinding area, and workpiece 5 provides signal to the PC control program after running into spacing adjustment piece 15, starts the decline of the mobile and unsteady pressure head 8 of workbench 9.
For guaranteeing the correct feed entrance point of workpiece 5, also stop 16 can be set on the stroke of expeller 13, when charging ram is run into stop 16, stop 16 sends signal and stops cylinder action.
Last material oil cylinder 13 in mobile oil cylinder 14, hoist cylinder 20 and the automatic feed mechanism in the above-mentioned Workpiece transfer mechanism is by HYDRAULIC CONTROL SYSTEM, and carry out programme-control with PC or PLC, guarantee that the requirement that workpiece clamp 6 is set by control program moves up and down and the automatic charge of workpiece 5 in workpiece clamp 6, and, realize workpiece grinding and automatic loading/unloading according to working cycles position section pre-set velocity and loading and unloading position.
The charging rate setting of workpiece is undertaken by following control program during the workpiece grinding: workpiece is during near the emery wheel edge, speed transfers slow-motion to by F.F., workpiece is crossed after the emery wheel work ring width slow-motion and is transferred to slowly and moving back, carry out the backhaul tarry matter, speed fell back on the loading and unloading position soon by moving back slowly to transfer to after workpiece went out the emery wheel outer rim.Can guarantee that like this crudy can improve working (machining) efficiency again.
Above-mentioned twin shaft, double-ring abrasive wheel end face working face outer edge finishing one suitable oblique angle are convenient to workpiece 5 and are entered, and help surplus and remove gradually.
Above-mentioned double abrasive wheel main shaft also can be done the adjustment of horizontal aspect, in order to adjust the double abrasive wheel end clearance, determines the workpiece stock removal.
Step during the workpiece grinding is as follows:
--------slow-motion--is moved back--the next material loading loop start of rewind down--pressure head rise--to material loading slowly in F.F. under the loss in head in startup.Existing division is as follows:
1, start-up control system is fixed on the expeller 11 that the workpiece clamp 6 on the work stage 9 adjusted to workpiece 5 automatic feed mechanisms by cylinder component 14 and is in same position.
2, by last material oil cylinder 13 workpiece 5 is advanced in the groove 61 of workpiece clamp 6, and by locking mechanism 62 lockings, workpiece 5 needs two faces of grinding all parallel with wheel face at this moment.If this grinding is back one circulation, the workpiece 5 that then last circulation grinding is good can be released in frock folder 6 automatically.
3, pressure head decline is depressed, and all locatees automatically when workpiece enters grinding area, and circulates up and down in emery wheel intercropping one by the movement velocity that configures, and gets back to the material loading position after grinding is good.
Repeat above-mentioned steps and just can constantly carry out the grinding of workpiece.
The travel speed and the distance and position of each section of above-mentioned workpiece 5 grindings circulation can be adjusted arbitrarily.
During as shown in Figure 6 sheet-like workpiece 5 of concrete grinding, serve as the location benchmark with the W face, emery wheel 1 and emery wheel 2 carry out grinding to U, the V face of workpiece 5 respectively.Two emery wheels can be done the adjustment at level and vertical direction inclination angle separately, suitably adjust by emery wheel 1, emery wheel 2 are made vertical angle, realize that U, V are in the face of the requirement of W face verticality precision.
