Abstract
The utility model discloses a pneumatic system for a double surface lapping machine and relates to a pneumatic system, which aims to provide a safe and reliable pneumatic system for the double surface lapping machine. The technical proposal of the utility model is that: the pneumatic system for the double surface lapping machine comprises an air passage between a cylinder lower cavity and an air source and an air passage between the cylinder upper cavity and the air source; a three position five-way valve is arranged between a one-way restrictor and a two position three-way valve of the air passage between the cylinder lower cavity and the air source through connection in series. The utility model is used for double surface precision lapping machines.
Description
Technical field:
The utility model relates to the pneumatic system of a kind of pneumatic system, particularly a kind of twin grinder.
Background technique:
The atmospheric control of existing accurate twin grinder master cylinder is made up of lower chamber of air cylinder gas circuit and upper chamber of air cylinder gas circuit, can realize the conversion of three kinds of pressure under this gas circuit normal condition, but will cause lower chamber of air cylinder pressure to descend suddenly in case occur in power failure suddenly or the air-channel system gas leakage taking place, last dish can fall rapidly, part of damage, even injury operator.
Summary of the invention:
The purpose of this utility model provides a kind of pneumatic system of safe and reliable twin grinder.The technical solution of the utility model is, a kind of pneumatic system of twin grinder, comprise gas circuit between lower chamber of air cylinder and source of the gas and the gas circuit between upper chamber of air cylinder and source of the gas, it is characterized in that: be connected in series a three position five-way valve between the one-way throttle valve of the gas circuit between lower chamber of air cylinder and source of the gas and the two position three-way valve.The utility model has lathe advantage safe and reliable to operation compared with the prior art.
Description of drawings:
Accompanying drawing is the pneumatic system schematic diagram of the utility model twin grinder.
Embodiment:
In conjunction with above-mentioned accompanying drawing the utility model is elaborated, analyzing existing pneumatic system causes the unexpected reason that descends of lower chamber of air cylinder pressure to be, two position three-way valve in the system under normal circumstances can proper functioning, but when occurring leaking air in power failure or the system, this two position three-way valve does not have the intermediateness of not conducting, can't make piston stop to descend.For head it off, be connected in series a three position five-way valve 5 between two position three-way valve 4 and the one-way throttle valve 6 in the gas circuit in existing pneumatic system between lower chamber of air cylinder and the gas source unit 1, its control principle is that electromagnet is charged when the three position five-way valve left side, then the work of position, a left side, be that P and A are logical, B and O pain, charged when the electromagnet on three position five-way valve the right, work in then right position, be that P and B are logical, A and O are logical; Two limit electromagnet are not charged when about three position five-way valve, then meta work, and promptly A, B, P, O are obstructed mutually.When if two position three-way valve is not charged, reduction valve 3 work, dish is for descending fast or rising at a slow speed on the lapping machine; And if two position three-way valve is charged, then reduction valve 2 work, dish is for descending at a slow speed or fast rise on the lapping machine, dish is worked under the decline state on the lapping machine, if in case take place to have a power failure or system's gas leakage accident, three position five-way valve will be in meta, cylinder 7 pistons will stop to descend, thereby upward dish also just stops to descend, and has avoided damage workpiece or casualty accident to take place.
Claims (1)
