Description
Technical field
The present invention relates to end axle-movable shaft mechanism, particularly relate to a kind of piston that uses this mechanism.The present invention provides the end axle-movable shaft mechanism that uses this piston simultaneously, and the equipment that uses this end axle-movable shaft mechanism.
Background technique
In machinery, need to realize to-and-fro motion in many instances and rotatablely move between mutual conversion.For example, reciprocating internal combustion engine need be converted to rotatablely moving of bent axle with the linear reciprocating motion that piston produces under the pressure of explosion of burning mixture promotes; In contrast, compressor need be converted to external motor-operated crankshaft rotating the linear reciprocating motion of piston.Above-mentioned two kinds of conversions are except the driving link difference, and it is consistent that motion of mechanism is required, and therefore, can realize that linear reciprocating motion is converted to the mechanism that rotatablely moves, and can be used for also generally that realizing rotatablely moves is converted to linear reciprocating motion.
Some linear reciprocating motions are provided under the prior art and have rotatablely moved the mechanism of conversion mutually.Usually under the technology, adopt connecting rod to realize above-mentioned conversion.Present most of internal-combustion engine, compressor all use connecting rod.The characteristics of this mechanism are, need to be connected between linear reciprocating motion spare and the rotating motion part by the connecting rod that swings back and forth, because the motion of connecting rod is to swing back and forth, this motion is a kind of compound movement, be difficult to carry out the inertia equilibrium of forces, and the swing of connecting rod can increase the side pressure of piston to the motion guide rail sidewall, cause the increase of frictional force, in addition, the existence of connecting rod also makes this mechanism need to possess certain length on vibration-direction, makes its size be difficult to further dwindle.
In order to address the above problem, prior art provide some kinds not with connecting rod back and forth-rotary motion conversion mechanism.For example, the application number that the applicant proposed on October 16th, 2009 is in 200910236026.5 the Chinese patent application, has proposed a kind of axle system that adopts end axle-movable shaft mechanism cooperates formation with reciprocating part reciprocal-rotation movement mutual conversion mechanism.In this mechanism, comprise at least two reciprocating parts, rotating motion part and the frame that supports this mechanism; Described rotating motion part is a system, comprises at the end axle at two ends and is connected two moving axis between the end axle; Rotatable being fixed on the frame of described end axle, and the running shaft of two end axles is located along the same line; Offer moving axis neck receiving hole on the end axle, the running shaft of the axis of this moving axis neck receiving hole and end spool is parallel, and is e apart from the distance of this running shaft; Described moving axis comprises moving axis neck, moving axis pin and moving axis arm; Described moving axis neck is a shaft part, is positioned at two ends, the moving axis left and right sides, and the axis of the moving axis neck at two ends is located on the same line; Described moving axis pin is similarly shaft part, have more than two sections or two sections, the axis of each moving axis pin all is parallel to the axis of described moving axis neck, and the moving axis pin axis also is e apart from the distance of moving axis neck axis, and adjacent moving axis pin spatially has 180 degree phase differences; Between moving axis neck and the moving axis pin and between the adjacent moving axis pin, connect by the moving axis arm; When forming described rotating motion part with described end axle, the moving axis neck of end shaft inserts the moving axis neck receiving hole of the end axle at two ends respectively, and with rotatable connection of moving axis neck receiving hole; Each moving axis pin correspondence at least is provided with a reciprocating part---and generally being piston, also can be dynamic balance slide block---and have the moving axis pin-and-hole that is enclosed within on the moving axis pin on the reciprocating part, the moving axis pin-and-hole is connected with the moving axis pin is rotatable; Described reciprocating part places the to-and-fro motion guide rail of frame; The to-and-fro motion guide rail of adjacent reciprocating part spatially has 90 degree phase differences.
Above-mentioned end axle-movable shaft mechanism, under the situation that does not need connecting rod, the mutual conversion that can realize back and forth-rotatablely move, overcome connecting rod to back and forth-the various adverse effects of rotary movement, can obtain that structure is more compact, running reciprocal-rotary motion conversion mechanism more stably.
Above-mentioned back and forth-rotary motion conversion mechanism in, piston plays the effect of the piston and the connecting rod of connecting rod simultaneously, obviously, it is also improper directly the piston of connecting rod in the prior art to be used for end axle-moving axis system.For example, the piston of end axle-movable shaft mechanism need be provided with the moving axis pin-and-hole, and the moving axis pin of moving axis will pass this hole.And moving axis has the many places return portion, can not directly pass the moving axis pin-and-hole.In addition, in end axle-movable shaft mechanism, piston can be that single action piston also can be a two-way ram.So-called two-way ram, promptly the two ends of piston all are provided with piston head.When this mechanism was used in the internal-combustion engine, then all as the bottom surface of firing chamber, the pressure of explosion alternating action of two firing chamber generations promoted the to-and-fro motion of piston to the end face of two piston heads on the end face of these two piston heads; When this mechanism was used in the compressor, then two piston heads all outwards did work by its end face.By above-mentioned two-way ram, can effectively improve the compactness of mechanism.Existing connecting rod piston then can't be realized this application mode.
Obviously, in the prior art, do not provide the piston that is fit to end axle-movable shaft mechanism characteristics, this obviously is unfavorable for giving full play to the advantage of this end axle-movable shaft mechanism.

The attachment hole 2-5 of described second portion 2 is divided into different two sections of internal diameter in the axial direction, wherein, one section internal diameter near bottom girder bottom surface 2-4-1 is bigger, and internal face is smooth, the unthreaded hole section 2-5-1 that is called attachment hole 2-5, the inner diameter values of the unthreaded hole section 1-5-1 of the attachment hole 1-5 of this unthreaded hole section 2-5-1 and described first portion 1 is identical.One section internal diameter away from described bottom girder bottom surface 2-4-1 of attachment hole 2-5 is smaller, and one through to bottom girder end face 2-4-2, makes this attachment hole 2-5 become through hole, and this section internal diameter is called through hole section 2-5-2.Described through hole section 2-5-2 is similarly unthreaded hole.Between described unthreaded hole section 2-5-1 and the described through hole section 2-5-2, with step transition towards described bottom girder bottom surface 2-4-1.
Also have the semicircle orifice 2-4-3 identical with the semicircle orifice 1-4-3 of described first portion 1 on the described second portion 2, above-mentioned two semicircle orifices can be combined into a complete circular hole.
Please referring to Fig. 6, this illustrates a setting sleeve 4, the internal diameter of the unthreaded hole section 2-5-1 of the unthreaded hole section 1-5-1 of the attachment hole 1-5 of the external diameter of this setting sleeve 4 and described first portion 1 and the attachment hole 2-5 of second portion 2 matches, and its internal diameter then external diameter of enough described screw 3 passes through.
During assembling, at first in two attachment hole unthreaded hole sections of first portion 1 or second portion 2, put into setting sleeve 4 respectively, one end of this setting sleeve 4 step surface in the hole that is connected because setting sleeve 4 is long, makes the length about half of this setting sleeve 4 stretch out attachment hole.After setting sleeve 4 installs, perhaps before this, the moving axis pin of moving axis is packed in the semicircle orifice of first portion 1 or second portion 2.
Then, the semicircle orifice of piston another part of the cover of installing and locating not 4 is inserted on the described moving axis pin, simultaneously, aim at one section insertion that described setting sleeve 4 exposes, each setting sleeve 4 is cooperated with the attachment hole unthreaded hole section in correspondence with each other of first portion 1 and second portion 2 respectively with the unthreaded hole section of attachment hole.At this moment, the corresponding attachment hole of first portion 1 and second portion 2 is relative respectively, and, because the effect of described setting sleeve 4 makes first portion 1 and second portion 2 mutual alignments obtain accurate in locating.
Then, two screws 3 are inserted from two openings of the attachment hole 2-5 of the bottom girder end face 2-4-2 of described second portion 2 respectively, until the tapped hole section 1-5-2 of the attachment hole 1-5 of described first portion 1, and screw 3 is screwed into this tapped hole section 1-5-2, after tightening, just realized the fixing of first portion 1 and second portion 2, whole piston assembling finishes.
After the above-mentioned installation, the semicircle orifice 1-4-3 of described first portion 1 and the semicircle orifice 2-4-3 of second portion 2 form a complete through hole, and the moving axis pin has passed this hole.
In the present embodiment, the attachment hole of one of them independent sector of described piston is provided with tapped hole, makes screw 3 can directly be screwed into this tapped hole and realizes fixing piston.This is because this piston adopts iron or steel to make, and on these materials tapped hole can be set.If piston is an aluminum, then, to offer tapped hole thereon and can't effectively bear the effect of fixing two parts because material is softer, can all be set to through hole this moment with the attachment hole of two independent sectors of piston, adopts double-screw bolt to connect two parts.Positioning meanss such as setting sleeve and attachment hole unthreaded hole section then still are provided with according to the foregoing description mode.
In the foregoing description, piston is a two-way ram, promptly have two piston heads, if single action piston, then only need one of them independent sector, another part is similar to the connecting rod cap of crank-connecting rod engine link major part for not having the piston base of piston head, as long as can be with described semicircle orifice sealing.The mode that the split surface of two parts can adopt prior art lower links such as side grain and scarf to adopt.As can be seen, piston provided by the invention is convenient to according to circumstances be combined as single action piston or two-way ram, has very strong flexibility.
The foregoing description is a preferred embodiment, in fact, the position that piston separates, as long as the moving axis pin-and-hole of piston can be divided into two semicircle orifices, described moving axis pin can be at first snapped in from the breach of the semicircle orifice of one of them piston portion of independently making, and the semicircle orifice that another one is independently made part can be fastened on the moving axis pin of the semicircle orifice that has snapped in preceding a part of piston; With two partial fixings of the above-mentioned piston of independently making respectively together, obtain complete piston and get final product then.For example, can be with the plane at piston longitudinal axis place as separating surface, two parts of piston moving axis pin-and-hole position vertically on respectively account for the position in half hole, both are spliced to form a complete moving axis pin-and-hole at longitudinal axis position.
In some cases, above-mentioned semicircle orifice even can not be lucky hemicycle, two semicircle orifices are not formed a complete circle yet, as long as two semicircles can both make described moving axis pin snap in from the opening in hole.At last, two piston portions of independently making are linked together.At this moment, the moving axis pin-and-hole that two parts of independently making of piston are formed not is complete circular hole, but comprises two breach, supports as long as described moving axis pin can obtain rotation therein.Certainly, technique scheme is not a preferred version, but and is not precluded within the less situation of load or other in particular cases use.
Although the foregoing description is piston is divided into two parts, in fact, also piston can be divided into three parts or more part, as long as each part all comprises a part of circular arc of moving axis pin-and-hole, each circular arc all can be fitted on the outer diametric plane of moving axis pin that should piston, and finally can various piece be combined into a complete piston by linkage structure and get final product.For example, two main parts of making separately are set, can encase the major part of moving axis pin after both are fixing, but also have a breach; The 3rd part is a dutchman, and this dutchman is placed in gap position, replenishes to obtain complete moving axis pin-and-hole.The installation that this structure is convenient to moving axis pin and moving axis pin-and-hole very much cooperates, but linkage structure is provided with too much.This mode of execution is not a most preferred embodiment of the present invention yet, does not use but do not get rid of under special circumstances.
In the foregoing description, each other fixedly connected of two independent sectors realized the location by the unthreaded hole that is arranged in the tapped hole, in fact, special location unthreaded hole can be set.Tapped hole then only plays fixation, like this, also can reach the effect of embodiment of the invention technological scheme.
