Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of piston ring testing, in particular to a device for quickly identifying the taper direction of a piston ring. Background Art
[0002] As a core engine component, piston rings play a key role in controlling air leakage and oil consumption. A piston ring assembly typically includes at least one outer conical ring to assist in oil scraping. During installation, the tapered end (usually the marking surface of the piston ring) must face the combustion chamber. While the processing of conical rings is a mature process, the industry still cannot guarantee 100% correct tapered orientation. Accurately identifying tapered orientation during marking on finished products has long been a challenge. While some equipment manufacturers have developed automatic visual recognition systems, there is still a significant risk of misjudgment for thin rings (ring height under 1.5mm), rings with small tapers, and rings with irregular tapers, thus remaining a complete solution. Summary of the Invention
[0003] Purpose of the utility model: In order to overcome the shortcomings of the background technology, the utility model seeks to protect a device for quickly identifying the taper direction of a piston ring.
[0004] Technical solution: The device for quickly identifying the taper direction of a piston ring disclosed in the utility model includes a conductive plate, an LED light, a power supply, and a vertical conductive block;
[0005] The vertical conductive block is placed on a conductive plate, and an insulating strip is provided on its vertical surface. The upper surface of the conductive plate is used to place a piston ring. When the small end of the piston ring faces upward, the back of the piston ring contacts the insulating strip; when the large end of the piston ring faces upward, the back of the piston ring contacts the vertical conductive block.
[0006] One pole of the power supply is connected to the LED lamp through a wire, and is connected to the conductive plate through the interface wire. The other pole is connected to the vertical conductive block through a wire, and is connected to another interface of the LED lamp through the interface wire. When the small end of the piston ring faces upward, the power supply supplies power to the LED lamp and the light turns on; when the large end of the piston ring faces upward, the power supply forms a short circuit and the light goes out.
[0007] Furthermore, the vertical conductive block is placed on the conductive flat plate through an insulating plate and fixed by insulating bolts.
[0008] Furthermore, a groove is provided on the conductive plate, and the vertical conductive block is placed in the groove.
[0009] Furthermore, the insulating strip is embedded in the vertical conductive block and arranged horizontally to keep the vertical surface flat.
[0010] Beneficial effects: Compared with the existing technology, the advantages of the utility model are: based on the photoelectric system, relying on the conductive performance of the piston ring, through the on and off of the current, to carry out identification, it can identify the cone direction of thin rings (ring height less than 1.5mm), small taper rings, and rings with irregular cone surfaces. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The vertical conductive stopper 4 is placed on the conductive plate 1, and an insulating strip 5 is provided on its vertical surface. The upper surface of the conductive plate 1 is used to place the piston ring 6. When the small end of the piston ring 6 faces upward, the back of the piston ring 6 contacts the insulating strip 5; when the large end of the piston ring 6 faces upward, the back of the piston ring 6 contacts the vertical conductive stopper 4.
[0014] The vertical conductive block 4 is placed on the conductive flat plate 1 through an insulating plate 7 and fixed by insulating bolts 8. A groove is provided on the conductive flat plate 1, and the vertical conductive block 4 is placed in the groove.
[0015] The insulating strip 5 is embedded in the vertical conductive block 4 and is arranged horizontally to keep the vertical surface flat.
[0016] One pole of the power supply 3 is connected to the LED lamp 2 through a wire, and is connected to the conductive plate 1 through the interface wire. The other pole is connected to the vertical conductive block 4 through a wire, and is connected to another interface of the LED lamp 2 through the interface wire.
[0017] After the LED light 2 is turned on, it is in a constantly on state. Place the piston ring 6 on the conductive plate 1. When the small end of the piston ring 6 faces upward, the power supply 3 supplies power to the LED light 2, and the light remains on, indicating that the taper direction of this ring is correct; when the large end of the piston ring 6 faces upward, it contacts the vertical conductive block 4 for conductivity, the power supply 3 forms a short circuit, and the light goes out, indicating that the taper direction of this ring is reversed.
