Abstract
The invention relates to a novel press release tester for a rubber-coated piston. The tester includes a rack. The upper end of the rack is provided with a cross beam capable of moving up and down. The lower end of the cross beam is provided with an upper pressing block. A lower pressing block is arranged below the rack. A pressure mold base is arranged on the lower pressing block. The pressure mold base is provided with an axially arranged through hole. The lower end of the upper pressing block is provided with a pressure mold corresponding to the through hole of the pressure mold base. The upper and lower ends in the through hole of the pressure mold base are provided with piston assemblies which are located beneath the pressure mold and on the lower pressing block respectively. An automobile shock absorber oil is filled between the two piston assemblies. A pressure sensor is arranged on the inner wall of the through hole of the pressure mold base. The pressure sensor is connected with a pressure display screen through a wire. The novel press release tester for the rubber-coated piston is simple in structure, convenient to operate, capable of well reflecting a rubber-coating effect of the piston assemblies through the pressure sensor so as to guarantee the quality of the rubber-coated piston so that normal work of a shock absorber is ensured.
Description
Technical field
The present invention relates to Novel glue coating piston pressure-off testing machine, belong to encapsulate piston machine checkout equipment technical field.
Background technology
Piston plays considerable effect in vibroshock.On outside piston in vibroshock, be substantially coated with film, prevent vibroshock in the course of the work, the oil in piston is from leaking out the normal work that affects vibroshock between piston and cylindrical shell.Piston is in encapsulation process, if encapsulate effect is bad, nest plate easily comes off from piston, thereby has affected the normal work of vibroshock, and this just needs piston to detect at the laggard line sampling of encapsulate, ensures the quality of encapsulate piston.
Summary of the invention
For above-mentioned defect, the object of the present invention is to provide simple in structurely, can detect the coated quality of nest plate of piston, guarantee the Novel glue coating piston pressure-off testing machine of the normal work of vibroshock.
The technical solution adopted in the present invention is for this reason: comprise frame, frame upper end is provided with crossbeam moving up and down, crossbeam lower end is provided with upper holder block, frame below is provided with lower lock block, lower lock block top is provided with stamper seat, stamper seat is provided with and is axially arranged with through hole, it is corresponding with the through hole of stamper seat that upper holder block lower end is provided with pressing mold, in the through hole of stamper seat, upper and lower two ends are provided with piston assembly and lay respectively at pressing mold below and lower lock block top, between two piston assemblies, fill automobile absorber oil, the through-hole wall of stamper seat is provided with pressure transducer, pressure transducer is connected with pressure display screen by wire.
Described piston assembly comprises the nest plate of piston and coated its cylindrical, nest plate and outer surface of piston composition hydraucone, piston upper end is provided with sealing gasket and by lock-screw and set nut, it is fixedly connected with piston, the through hole of the complete packed-piston of sealing gasket upper end, the hydraucone of two piston assemblies is facing to being positioned at stamper seat.
The side of described pressing mold is provided with leakage of oil groove.
Advantage of the present invention is: the present invention is simple in structure, simulate duty in vibroshock and detect the covered effect of the nest plate of encapsulate piston by encapsulate piston, and be reacted on pressure display screen by pressure transducer, thereby can detect accurately nest plate covered effect, to ensure the normal work of follow-up vibroshock.
