Description
Technical field
The present invention relates to Compressor Technology field more particularly to a kind of adjustable Split connecting rods of reciprocating compressor length.
Background technique
Reciprocating compressor belongs to positive displacement compressor, is that the gas of a constant volume is made sequentially to suck and be discharged closing sky
Between compressor.By the operating of motor, crankshaft connecting rod system is driven to push reciprocating motion of the pistons, compressor complete air-breathing,
Compression, exhaust, expansion Four processes.The movement of connecting rod can regard big end as and act as with crank-pin (crankshaft eccentric shaft) one
Rotary motion, small end of connecting rod is reciprocating together with piston pin, therefore connecting rod is to make plane rocking movement in linkage plane, right
In using cylinder diameter of the same race, different eccentricity generally to use connecting rod center to obtain the compressor design scheme of different trips volume
Away from remaining unchanged, and adjust the service requirement that piston pitch and length make piston meet compressor.
Existing compressor connecting bar has the disadvantages that existing connecting rod regular length is constant, but to meet different sections
Away from and length pistons processing, piston blank mold need to design more sets, this allows for the reduction of piston blank versatility, increases zero
Part inventory, at the same also cause processing when piston material significant wastage, cause Piston Machining inefficiency；Existing variable-length
The connection of connecting rod fission is unreliable, and needs accessory more；As long as one end is worn in unitary link, i.e., whole replacement.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of reciprocating compressor proposed is long
Spend adjustable Split connecting rod.
To achieve the goals above, present invention employs following technical solutions:
A kind of adjustable Split connecting rod of reciprocating compressor length, it is characterised in that: including first connecting rod and second connecting rod, in institute
A first through hole is arranged in the one end for stating first connecting rod, and a guide rod is arranged far from one end of first through hole in first connecting rod,
In one end of the second connecting rod, one the second through-hole is set, it is recessed in one end setting one of the second connecting rod far from the second through-hole
A third through-hole is arranged in slot in groove, and a nut is arranged in third through-hole, and guide rod sequentially passes through groove, third
Through-hole and nut are cooperatively connected, and one group of fourth hole is arranged on nut, and a bolt is arranged in any one fourth hole.
Preferably, the guide rod is square structure, and external screw thread is arranged on the guide rod.
Preferably, the groove is square structure, the axis of the axis of the third through-hole perpendicular to the groove.
Preferably, the nut rotates in the third through-hole.
Preferably, the fourth hole annular is evenly arranged on the nut.
The present invention has the advantages that the configuration of the present invention is simple, is connected through a screw thread, connection type is reliable and adjustment is facilitated to connect
The distance between bar major part and microcephaly can only replace wherein one when a wherein abrasion, not need whole replacement, drop
The low cost for changing part, improves economic effect of the invention.

Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in Figure 1, Figure 2 and Figure 3, a kind of adjustable Split connecting rod of reciprocating compressor length provided by the invention,
It is characterized in that: including first connecting rod 1 and second connecting rod 2, one first through hole 3 being set in one end of the first connecting rod 1, the
A guide rod 4 is arranged far from one end of first through hole 3 in one connecting rod 1, and the guide rod 3 is square structure, in the guiding
External screw thread is set on bar 3, so that guide rod 3 can not only be threadedly engaged nut, while guiding role can also be played.
One the second through-hole 5 is set in one end of the second connecting rod 2, in the one end of second connecting rod 2 far from the second through-hole 5
One groove 6 is set, and the groove 6 is square structure, and the guide rod 3 is stuck in groove 6, and one is arranged in groove 6
A nut is arranged perpendicular to the axis of the groove 6 in third through-hole 7, the axis of the third through-hole 7 in third through-hole 7
8, the nut 8 is coaxially arranged with the groove 6, and the nut 8 rotates in the third through-hole 7, and guide rod 4 is successively worn
Cross groove 6, third through-hole 7 is threadedly coupled with nut 8, six fourth holes 9 of setting on nut 8, between the fourth hole 9 is equal
Away from being laid in one week of the nut 8, a bolt 10 is set in any one fourth hole 9, bolt 10 is to by nut 8
It is fixed on guide rod 4.
The working principle of the invention: first connecting rod 1 and second connecting rod 2 are cooperated with corresponding link mechanism respectively connect first
It connects, guide rod 3 is then passed through into nut 8 and is stuck in groove 6, rotating nuts 8, so that between first connecting rod 1 and second connecting rod 2
Spacing reaches the length of required link mechanism, and then bolt 10 is placed in fourth hole 9, and bolt 10 is tightened.
