Abstract

The utility model relates to a piston ring anchor ear device, which mainly solves the problems that the assembly of the piston ring is time-consuming and labor-consuming, the oil ring and the gas ring can be damaged or broken, the service life of the anchor ear is short, etc. The utility model comprises two semicircular buckle bodies, a positioning slide bar and a plurality of draw off devices; both ends of the positioning slide bar are respectively inserted into the buckle body to make the two semicircular buckle bodies connected mutually; the draw off devices are respectively arranged at both ends of the buckle body, and one draw off device comprises a hand handle, a connecting bar and a sliding block; one end of the connecting bar is moveably connected with a convex block which is positioned on the buckle body, and the other end is moveably connected with the sliding block; the sliding block is suited on the hand handle, one end of the hand handle is moveably connected with the convex block which is positioned on the buckle body, and the hand handle matches with the sliding block through a screw thread; the hand handle is turned to make the draw off devices of the both sides of the anchor ear tightened at the same time, the two buckle bodies are healed, and positioned at the inlet of the air cylinder, and then the piston can be pulled into the air cylinder. The anchor ear is firm to use, easy to operate, energy saving, and quick without damaging the oil ring and the gas ring.

Description

Piston ring anchor ear device

Technical field

The utility model relates to the engine erection unit, and particularly piston ring is installed.

Background technology

In the engine installation process, the installation of special piston ring needs the piston anchor ear that resilient piston ring is retracted in the piston ring groove, and the ring footpath is slightly less than cylinder bore diameter, and piston component is slipped in the cylinder smoothly.

The anchor ear of the various types that uses usually and see all is to be hoop by iron sheet, copper sheet, mixes tightening component, occurs tightening up not in place in the use, and ring footpath is greater than the cylinder sleeve internal diameter, the sliding not inlet casing of piston; Receive tension, seized piston is sliding motionless; Tighten up just when good, the piston band ring and is slided into one, two roads in the cylinder, and the 3rd road has been stuck again and has not slidingly advanced.Reason be anchor ear when embracing three road rings whole tension force that is all encircled support, after sliding into one or two road rings, the stressed disequilibrium of hoop face, the ring that does not slide into is stressed little and eject the ring footpath greater than the cylinder sleeve internal diameter, assembling is obstructed.Will repeatedly tighten up anchor ear like this, not only waste time and energy, and can cause oil, the damage of vapour ring or split folding, the anchor ear life-span is short.

Summary of the invention

The retractable anchor ear easily, easily and fast when the purpose of this utility model was to make ring installation.

For achieving the above object, it comprises two semicircle hoop bodies, locating slide rod and draw off gears the utility model; Respectively there is a projection in the outside, described semicircle hoop body two ends, offers through hole and draw-in groove on this projection respectively, and through hole is inserted at the two ends of locating slide rod respectively, and two semicircle hoop bodies are connected, and locating slide rod is threaded;

Described draw off gear is arranged at the two ends of hoop body respectively, comprises handle, connecting rod, slide block; Projection on this connecting rod one end and the hoop body flexibly connects, and the other end and slide block flexibly connect; Said slide block set is located on the handle, and the projection on this handle one end and the hoop body flexibly connects, and handle and slide block are threaded engagement.

The utility model is owing to adopt lever-type draw off gear, and hoop body is that rigid material is made, and the utility model is easy to operate, laborsaving, quick, sturdy and durable, does not damage oil, vapour ring.

Description of drawings Fig. 1 is the structural representation under the utility model relieving state.Fig. 2 tightens up structural representation under the state for the utility model.

The specific embodiment

As shown in Figure 1, the utility model it comprise two semicircle hoop bodies 1,6, locating slide rod 5 and draw off gears; Respectively there is a projection 11,61 in the outside, described semicircle hoop body 1,6 two ends, offer through hole 111,611 and draw-in groove 112,612 on this projection 11,61 respectively, through hole 111,611 is inserted at the two ends of locating slide rod 5 respectively, and two semicircle hoop bodies 1,6 are connected, and locating slide rod 5 is threaded;

Described draw off gear is arranged at the two ends of hoop body 1,6 respectively, comprises handle 2, connecting rod 3, slide block 4; Projection 11 on these connecting rod 3 one ends and the hoop body 1 flexibly connects, and the other end and slide block 4 flexibly connect; Said slide block 4 is sheathed on the handle 2, and the projection 61 on these handle 2 one ends and the hoop body 6 flexibly connects, and handle 2 is a threaded engagement with slide block 4.

During ring installation, top land is placed downwards, the utility model is decontroled, and hoop body 1,6 is enclosed within the piston region that installs piston ring and flushes with upper and lower ring if stagger available backing plate leveling, and hoop body 1,6 heals up and the opening that encircles staggers, handle 2 switchings, the draw off gear on anchor ear both sides is tightened up simultaneously, and hoop body 1,6 closes up, and handle 2 switchings to the draw-in groove 112,612 and the rotation of projection 11,61 puts in place until handle 2, be put into the cylinder porch, piston can be pushed in the cylinder.
