The specific embodiment:
Among Fig. 1,2, the pneumatic means of twin grinder, bed piece (36) lining device has three cylinders (31), on the piston rod of cylinder, fixing bull gear (35), processed workpiece device is in the planetary gear holding tank, centre wheel and planetary gear engagement, planetary gear meshes with bull gear and centre wheel simultaneously, and the rotation of centre wheel makes workpiece along the circumferential direction rotate with planetary gear; At the left side of grinder lathe bed returning apparatus top lap cylinder (30) is arranged; The trimmer cylinder (32) of the left rear side device one control trimmer advance and retreat of bed piece; Each cylinder is by pressure regulator valve, reversal valve and flow speed control valve control cylinder gas circuit; Be contained in the top lap cylinder the column in lathe bed left side, cylinder piston rod is fixedlyed connected with the rocking arm left end, and the other end of rocking arm connects top lap (34) by last main shaft, and last main shaft is connected with the rolling bearing for rocker arm assembling; Fixing the trimmer seat for left back at lathe, trimmer cylinder (32) is fixed on the trimmer seat, and cylinder piston rod is connected with stick, and the trimmer cylinder is being controlled the advance and retreat of stick, and dressing diamond is housed on the stick.
The pneumatic means of this twin grinder, on coil the lift cylinder operating principle: not during air feed, cylinder falls after rise to upper/lower positions; During the start air feed, default conditions are: high pressure gas enters the cylinder bottom through two position three-way valve 8, shuttle valve 28, unidirectional flow speed control valve 3, two position two-way valve 1, and (valve 3 is an inlet channel at this moment, no speed governing effect), the cylinder exhaust is discharged via unidirectional flow speed control valve 4, two position three-way valve 5.The speed that cylinder rises is regulated by valve 4.Wherein two position two-way valve 1 is to go up dish fast rise magnetic valve, in process, and during valve 1 energising, dead end, high pressure gas then enters the cylinder bottom through unidirectional flow speed control valve 2, at this moment the valve 2 and the valve 4 common cylinder rates of climb of regulating.
When valve 8, valve 16, valve 5 energisings, high pressure gas enters upper chamber of air cylinder through valve 16,12,7,5,4, and the cylinder exhaust is discharged via valve 2,3,28,8,9,13, and last dish descends.
In first pressing (low pressure) process segment, valve 8,13,14,5,25 energisings, this moment, high pressure gas entered lower chamber of air cylinder via valve 13,9,28,3,2,1, entered upper chamber of air cylinder through valve 14,10,7,5,4 simultaneously, and wherein valve 6,10,25 is a pressure-reducing valve.The gas pressure that enters dish cylinder upper and lower cavity offsets back formation than low tonnage.
Press (high pressure) process segment main, valve 8,13,15,5 energisings, this moment, high pressure gas entered lower chamber of air cylinder via valve 13,9,28,3,2,1, entered upper chamber of air cylinder through valve 15,11,7,5,4 simultaneously, and wherein valve 6,11,25 is a pressure-reducing valve.Enter and form higher tonnage after the gas pressure that coils the cylinder upper and lower cavity offsets.
Final stage in fabrication cycles is the zero-pressure process segment, valve 8,13 energisings, and this moment, high pressure gas entered lower chamber of air cylinder via valve 13,9,28,3,2,1, and wherein valve 6,9 is a pressure-reducing valve.Gas pressure and the last dish deadweight that enters the dish upper chamber of air cylinder back that offsets forms zero-pressure, realizes that zero-pressure processes.
Generally speaking, as shown in Figure 2: valve 8 is last dish rising path, and valve 13,9 is zero-pressure processing path, and valve 14,10 is low pressure processing path, and valve 15,11 is high pressure processing path, and valve 16,12 is for regulating the path of going up the dish falling pressure.
Bull gear lift cylinder operating principle: not during air feed, cylinder falls after rise to upper/lower positions; During normal air feed, regulate admission pressure by valve 20, default conditions are: high pressure gas enters cylinder bottom (valve 23 is an inlet channel at this moment, no speed governing effect) through two position three-way valve 21, unidirectional flow speed control valve 23, and the cylinder exhaust is discharged via unidirectional flow speed control valve 24, two position three-way valve 22.The speed that cylinder rises is regulated by valve 24.When valve 21 and 22 when electric, high pressure gas enters cylinder top (valve 24 this moment inlet channel just, no speed governing effect) through two position three-way valve 22, unidirectional flow speed control valve 24, the cylinder exhaust is via unidirectional flow speed control valve 23, two position three-way valve 21 discharges.The speed that cylinder descends is regulated by valve 23.Flow speed control valve all is located on the exhaust channel in this loop, can make the inblock cylinder air cavity form certain back pressure, guarantees bull gear lifting reposefully.
Trimmer advance and retreat cylinder operating principle: the trimmer normal position is for returning; During normal air feed, regulate admission pressures by valve 19, default conditions are: high pressure gas enters the cylinder left part through position, three-position four-way valve 18 left side, and the cylinder exhaust is discharged via valve 18, unidirectional flow speed control valve 17, and the speed that cylinder retreats is regulated by valve 17; When valve 18 was pulled meta, the trimmer cylinder can rest on the optional position; When valve 18 was pulled right position, high pressure gas entered the cylinder right part through three-position four-way valve 18 right positions, and the cylinder exhaust is discharged via valve 18, unidirectional flow speed control valve 17, and the speed that cylinder advances is regulated by valve 17.Equally, flow speed control valve is located on the exhaust channel in this loop, can make the inblock cylinder air cavity form certain back pressure, and the assurance trimmer can be advanced and retreat reposefully, thereby guarantees dressing accuracy.
In this pneumatic system, all on exhaust channel, be provided with unidirectional flow speed control valve, can form back pressure at the inblock cylinder air cavity, make that each action all can even running.
