Description
Technical Field
The utility model belongs to the machining field relates to a quartering hammer combined type piston ring.
Background
The hydraulic breaking hammer is an important engineering machine which uses hydraulic energy as power to drive a piston positioned in an upper cylinder body of a hydraulic cylinder to do reciprocating motion, a drill rod is hammered by the piston to transmit energy to the drill rod, and the energy on the drill rod is absorbed by a struck object, so that the struck object is broken, the hydraulic breaking hammer is mainly used for the work of breaking, dismantling, hard layer excavation and the like in building construction, is usually installed on an excavator, a loader or a power station, and has the advantages of large impact force, convenience in use, good maneuverability, high efficiency and the like.
Hydraulic pressure quartering hammer mainly installs and is used for carrying out the crushing operation to the stone on mechanical device, and its theory of operation is comparatively simple, and the reciprocating cycle mainly through the piston drives the drill rod and stretches out and draws back, lets the tip of drill rod hit the stone and carry out the crushing operation, but piston ring structure in the present quartering hammer is simple single, piston ring intensity is not high leads to the fact piston ring life not high, has also influenced the life of quartering hammer simultaneously.
Disclosure of Invention
The utility model aims at providing a simple structure, reasonable in design's combined type piston ring to the above-mentioned problem that exists among the prior art.
The purpose of the utility model can be realized by the following technical proposal: the utility model provides a quartering hammer combined type piston ring, includes the piston ring body, its characterized in that, piston ring body both ends cover be equipped with O type sealing washer, piston ring body a terminal surface be provided with the copper ring holder, copper ring holder one end and piston ring body one end support each other and lean on the installation, the copper ring holder in be provided with the copper ring, the copper ring on seted up a plurality of annular balancing grooves.
In foretell quartering hammer combined type piston ring, piston ring body both ends face on all set up the step that supplies O type sealing washer fixed mounting, radially set up a plurality of recess on the internal perisporium of piston ring body, recess quantity be four, can divide into first recess, second recess, third recess and fourth recess, just second recess and third recess between be provided with and inlay the copper snap ring on the piston body inner wall.
In the compound piston ring of the breaking hammer, the inner wall of the copper ring holder is provided with a mounting groove for fixedly mounting the copper ring, and the inner wall of the copper ring holder is in clearance fit with the copper ring.
In the compound piston ring of the breaking hammer, the number of the balance grooves is four.
Compared with the prior art, the breaking hammer composite piston ring has the following advantages:
1. this quartering hammer combined type piston ring structure is simple, long service life, reasonable in design and piston ring intensity are high, can adapt to high strength operational environment.
2. The piston ring in this quartering hammer combined type piston ring adds the copper snap ring in, strengthens the holistic intensity of piston ring, and the setting of copper snap ring plays the wearing and tearing that reduce the piston ring, has the advantage that improves piston ring life.
3. This quartering hammer combined type piston ring supports to lean on and installs the copper ring holder, has strengthened the practicality of piston ring, has improved piston ring life.
