Abstract
The utility model provides an air compressor piston which belongs to the technical field of machinery and solves the problem that the service life is short due to the expansion as the existing air compressor piston is easily heated during working. The air compressor piston comprises a piston body, wherein a through hole transversely penetrating through the piston body is arranged in the middle of the outer side wall of the piston body, an annular gas groove and an annular oil groove are arranged on the outer side wall of the piston body, and the through hole is provided with grooves arranged two openings of the outer side wall of the piston body respectively. The air compressor piston has the advantages of simple structure and long service life.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of piston, particularly a kind of piston that is applied on the air compressor.
Background technique
Generally all use piston on the air compressor; Piston wall is generally all thinner, and piston when high speed operation easily heating expand the position of piston rod that is used to peg graft, piston hole place particularly; Cause seizure of piston to change motionless problem, thereby further influence the working life of piston.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of simple in structure, long service life, can prevent the air compressor piston that the piston heating is expanded.
The purpose of the utility model can realize through following technical proposal: a kind of air compressor piston; Comprise piston body; Described piston body outer side wall middle part offers the through hole of lateral direction penetrating piston body; Also offer annular gas tank and annular oil groove on the described piston body outer side wall, it is characterized in that, two openings of described through hole on the piston body outer wall all offer groove.
In above-mentioned air compressor piston, the degree of depth of described groove is 0.4mm～0.6mm.As preferred version, the degree of depth of groove is that 0.5mm is best.
In above-mentioned air compressor piston, the wall thickness of described piston body is 4.5mm～6.5mm.As preferred version, the degree of depth that the wall thickness of piston body is is that 5mm is best.
In above-mentioned air compressor piston, described groove shapes is the diameter of the width of rectangular and described groove greater than through hole.
At the above-mentioned piston on the air compressor that is used for, offer several in the described annular oil groove and communicate and equally distributed oil through with piston body inside.
Compared with prior art; This air compressor piston through all offer at two openings of through hole groove alleviate the piston wall heating of through hole expand the formed new piston wall wall thickness in back still less than or be equal to the piston wall wall thickness of other positions; Making so just can effectively solve because piston generates heat when high speed operation causes seizure of piston to change motionless problem, simple in structure, long service life when expanding.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the sectional structure schematic representation of the utility model.
Among the figure, 1, piston body; 2, annular gas tank; 3, annular oil groove; 4, through hole; 5, groove; 6, oil through.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
As depicted in figs. 1 and 2, this air compressor piston comprises piston body 1, and the wall thickness of piston body 1 is 4.5mm～6.5mm, and in the present embodiment, the degree of depth that the wall thickness of piston body 1 is is 5mm.Piston body 1 outer side wall middle part offers the through hole 4 of lateral direction penetrating piston body 1, also offers annular gas tank 2 and annular oil groove 3 on piston body 1 outer side wall, wherein offers in the annular oil groove 3 a plurality ofly to communicate and equally distributed oil through 6 with piston body 1 inside.Two openings of through hole 4 on piston body 1 outer wall all offer groove 5, and groove 5 is shaped as the diameter of the width of rectangular and groove 5 greater than through hole 4, and the degree of depth of groove 5 is 0.4mm～0.6mm, and in the present embodiment, the degree of depth of groove 5 is 0.5mm.
Through all offer at two openings of through hole 4 groove 5 alleviate the piston wall heating at through hole 4 places expand the formed new piston wall wall thickness in back still less than or be equal to the piston wall wall thickness of other positions, make so just can effectively solve and cause the motionless problem of seizure of piston commentaries on classics when expanding because piston generate heat when high speed operation.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
