It is located to set assembly through-hole periphery and offer and sets the annular of counterweight blind hole and underlying counterweight blind hole on corresponding position for being connected to and match
Repeated hole, the preposition counterweight blind hole, postposition counterweight blind hole, on set counterweight blind hole, underlying counterweight blind hole and with inside repeated hole
Fill out the lead powder for promoting piston only local gravity.
Further, the preposition counterweight blind hole, postposition counterweight blind hole and on to set counterweight blind hole upper end opening position equal
Offer internal screw thread sealing hole.
Further, the internal screw thread sealing hole internal whorl is connected with for being closed preposition counterweight blind hole, postposition is matched
Weight blind hole and the external screw thread plug for above setting counterweight blind hole upper end opening.
Further, the preposition counterweight blind hole, postposition counterweight blind hole, on set counterweight blind hole, underlying counterweight blind hole and
It is identical with repeated hole internal orifice dimension size.
Further, the preposition counterweight blind hole sets the distance between assembly through-hole and corresponding position postposition counterweight in
It is identical that blind hole sets the distance between assembly through-hole in.
The invention has the advantages that the compressor piston of porous longitudinal counter weight device built in one kind of the invention by
Opened up inside piston only preposition counterweight blind hole, postposition counterweight blind hole, on set counterweight blind hole, underlying counterweight blind hole and with repeated hole,
According to actual needs to the counterweight ratio for filling lead powder to change different location is filled out inside counterweight blind hole, thus balanced each column piston matter
Amount balances reciprocal inertia force, guarantees the even running of compressor.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is sectional view of the invention.
In figure: 1. piston onlies set assembly through-hole in 2., 3. preposition counterweight blind holes, 4. postposition counterweight blind holes, set and match on 5.
Weight blind hole, 6. underlying counterweight blind holes, 7. match repeated hole, 8. lead powder, 9. internal screw thread sealing holes, 10. external screw thread plugs.
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
The compressor piston of porous longitudinal counter weight device, including piston only 1, piston built in Fig. 1 and one kind shown in Fig. 2
1 inner hub location of ontology, which is offered, sets assembly through-hole 2 for installing in fixed piston rod, 1 upper surface of piston only is located at
In set and offer 2 preposition counterweight blind holes 3 on front side of assembly through-hole 2,1 upper surface of piston only be located in set 2 rear side of assembly through-hole
Offer 2 postposition counterweight blind holes 4,1 upper surface of piston only be located in set assembly 2 upper end of through-hole and offer and set counterweight on 2
Blind hole 5, piston only 1 be internally located in set assembly 2 lower end of through-hole offer 2 with above set counterweight blind hole 5 match it is underlying
Counterweight blind hole 6, piston only 1 be internally located in set assembly 2 periphery of through-hole and offer that set counterweight blind for being connected on corresponding position
The ring-shaped weight hole 7 in hole 5 and underlying counterweight blind hole 6, preposition counterweight blind hole 3, postposition counterweight blind hole 4, on set counterweight blind hole 5, under
Set counterweight blind hole 6 and with the lead powder 8 filled out inside repeated hole 7 for promoting 1 local gravity of piston only.
Further, preposition counterweight blind hole 3, postposition counterweight blind hole 4 and on set 5 upper end opening position of counterweight blind hole and open up
Have internal screw thread sealing hole 9, further, 9 internal whorl of internal screw thread sealing hole be connected with for be closed preposition counterweight blind hole 3, after
It sets counterweight blind hole 4 and above sets the external screw thread plug 10 of 5 upper end opening of counterweight blind hole, further, preposition counterweight blind hole 3, postposition
Counterweight blind hole 4, on set counterweight blind hole 5, underlying counterweight blind hole 6 with 7 internal orifice dimension size of repeated hole it is identical, it is further, preposition to match
Weight blind hole 3 and in set assembly the distance between through-hole 2 and corresponding position postposition counterweight blind hole 4 and in set between assembly through-hole 2
Compressor piston apart from longitudinal counter weight device porous built in identical, of the invention one kind inside piston only 1 by opening up
Preposition counterweight blind hole 3, postposition counterweight blind hole 4, on set counterweight blind hole 5, underlying counterweight blind hole 6 and with repeated hole 7, according to actual needs
The counterweight ratio for filling lead powder 8 to change different location is filled out inside to counterweight blind hole, so that balanced each column piston mass, balance are reciprocal
Inertia force guarantees the even running of compressor.
Piston common used material density (g/cm3): cast aluminium 2.68, gray cast iron 7.35, steel 7.85.And the density of lead
It is 11.34, is approximately 4.23 times of cast aluminium, 1.54 times of gray cast iron, 1.44 times of steel, therefore the increasing of piston can be used as
Heavy material.
It first drills on piston, then fills lead in threaded hole, thread locking glue is then smeared on screw plug and threaded hole, and
With the stifled real threaded hole of screw plug, the flat piston end surface of most rear car.
Taking the above-mentioned ideal embodiment according to the present invention as inspiration, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
