Abstract
The invention provides a device and a method for automatically detecting end gaps of piston rings and sorting the piston rings. The device comprises a worktable, a ring arrangement motor, a programmable logic controller (PLC) system, a feeding push plate, a loading frame arranged in front of the feeding push plate, a detection die, an electronic dial indicator arranged on the detection die, a plurality of discharge ports and a lifting cylinder, wherein the ring arrangement motor is used for providing feeding power required by the feeding push plate. During work, the feeding push plate feeds the piston rings to be detected into the open detection die, the electronic dial indicator displays detection dimension data and transmits the data to the PLC system when the detection die is closed, and the system performs analysis and discrimination according to the data and sorts the piston rings; and the system feeds various piston rings into the specified discharge ports by blowing compressed air, so that the aim of automatic sorting is fulfilled. The device for automatically detecting the end gaps of the piston rings and sorting the piston rings is adjustable in detection speed and high in work efficiency and is accurate and reliable.
Description
Technical field
The present invention relates to a kind of checkout gear, particularly a kind of automatic inspection of piston ring end gap sorting equipment and method.
Background technology
Piston ring is the inner core component of fuel engines, it and cylinder, and piston, cylinder wall etc. are accomplished the sealing of fuel oil-gas together.Piston ring comprises compression ring and oil ring, and the effect of piston ring comprises sealing, regulates effects such as machine oil, heat conduction, guiding.The compression ring piston ring can seal combustion gas, does not allow the gas of combustion chamber to drain to crankcase, is controlled at bottom line to the leakage rate of gas, improves the thermal efficiency, and gas leakage not only can make the power of engine descend, and can make machine oil rotten; The oil ring piston ring can scrape lubricating oil unnecessary on the cylinder wall, makes again simultaneously and is furnished with very thin oil film on the casing wall, guarantees the normal lubricated of cylinder and piston and ring, on the high speed engine, payes attention to the effect of piston ring control oil film especially in modern times; In addition, also can conduct to cylinder sleeve, promptly play cooling effect through the heat of piston ring with piston.
The working surface of piston ring must not have indentation, abrades, peel off, and should there be certain fineness external cylindrical surface and upper and lower end face, and the required precision in the elastic force of curvature, piston ring, gap etc. is very high; , all need pass through in piston ring accurate detection letter sorting after creating, to guarantee the quality requirement of harsh product.
Summary of the invention
In order to satisfy the quality testing requirement of piston ring, the present invention proposes a kind of automatic inspection of piston ring end gap sorting equipment and method, to guarantee the required precision of piston ring.
For reaching the object of the invention, automatic inspection of piston ring end gap sorting equipment of the present invention comprises workbench, reason ring motor, PLC control system, feeding push pedal, is arranged on the anterior stock shelf of feeding push pedal, detects mould, is arranged on the electronics amesdial, a plurality of discharging opening and the material lift cylinder that detect on the mould; Wherein reason ring motor is in order to provide feeding push pedal feeding required power; During work, send into the detection mould of open configuration to piston ring to be detected by the feeding push pedal, close up that the electronics amesdial shows that detecting the size transfer of data controls system to PLC when detecting mould, system differentiates according to data analysis piston ring is classified; Utilizing compressed air to blow by system's control then sends all kinds of piston rings into the appointment discharging opening, reaches automatic letter sorting.
Its detection speed of automatic inspection of piston ring end gap sorting equipment of the present invention is adjustable, high efficiency, accurately and reliably.
