Description
Technical field
What the present invention relates to is a kind of mechanical adjustment structure that is used for mechanical transmission, but the mechanism that especially a kind of one-way synchronization is regulated belongs to the mechanical transmissioning technology field.
Background technique
In mechanical transmission mechanism, a kind of mechanism that circular movement can be converted to straight reciprocating motion is arranged, as inline slidercrank mechanism, a complete inline slidercrank mechanism is by crank, connecting rod, slide block and slide bar are formed; Wherein the movement locus of crank is a circular movement, and the movement locus of slide block is the certain straight reciprocating motion of stroke.When crank radius was adjustable and it is adjusted, the mid point of the movement locus of slide block remained unchanged, and was benchmark two-way increase or reduce the length that crank is regulated in both sides with the mid point.When said mechanism is used in reality, can't be implemented in the adjusting of carrying out slide block movement track length under the certain situation of slide block end points, mainly be because lack effective adjusting parts on the structure, thereby influenced the effect of its individual event synchronization regulation in mechanical transmission.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned existence, and provide a kind of rational in infrastructure, compact, easy to use, reliable, synchronization regulation precision height, the unidirectional synchronous regulation mechanism that scope is big.It is made up of slider part and crank part at least, and it also includes by handwheel, hand wheel pole, and the hand wheel pole cover, doubly apart from the double thread screw drive link, gear keeps drive lead screw and regulates the adjusting parts that drive lead screw constitutes; Be a hollow pipe doubly wherein apart from the double thread screw drive link, the inwall at two ends has attacked tapped hole and direction is opposite, wherein near the pitch of crank part one end be close slider part one end pitch 1/2nd, the outer wall in stage casing is milled with keyway, and is connected with key with gear.
Described times apart from the tapped hole at double thread screw drive link two ends respectively with being threaded maintenance drive lead screw and regulate drive lead screw; Wherein keep drive lead screw to link to each other, link to each other with slider part and regulate drive lead screw with crank part.
Described crank part is made up of crank, adjusting screw mandrel and regulating block; Regulating screw mandrel is the screw mandrel that an end has the specific adjusted position groove of shape, has and regulate the corresponding tapped hole of screw mandrel in the middle of the regulating block, and the one side has cylindrical protrusions to be connected with keeping drive lead screw.
The adjusted position groove of described adjusting screw mandrel end matches with the hand wheel pole end, the hand wheel pole of band handwheel is set in the hand wheel pole cover that is fixed on the mainboard, and two positions that the gear on the hand wheel pole and the gear on the double thread screw drive link doubly can be in engagement or throw off, simultaneously the terminal adjusted position groove with adjusting screw mandrel end of hand wheel pole also the corresponding position in two positions that combine or throw off.
Described slider part is made up of slide block and slide bar; Slide block does reciprocating linear motion on slide bar, and a side of slide block has cylindrical protrusions to be connected with the adjusting drive lead screw.
The invention belongs to a kind of improvement to prior art, it utilizes screw mandrel and gear transmission, has reached when crank radius is regulated, and an end end points of slide block movement track remains unchanged the effect that path length changes.It has rational in infrastructure, compact, and is easy to use, reliable, characteristics such as synchronization regulation precision height, scope are big.

Embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: shown in Figure 1, the present invention mainly is made up of slider part, crank part and adjusting parts etc.Slider part and common inline slidercrank mechanism are similar, and it is made up of slide block 13 and slide bar 14; Slide block 13 does reciprocating linear motion on slide bar 14, and a side of slide block 13 has cylindrical protrusions to be used for connecting adjusting drive lead screw 7.
In conjunction with the accompanying drawings shown in 2, crank part of the present invention and common inline slidercrank mechanism are distinguished to some extent, it by crank 1, regulate screw mandrel 2 and regulating block 3 is formed.Adjustable lever 12 is that an end has the specific adjusted position groove of shape, has and adjustable lever 2 corresponding tapped holes in the middle of the regulating block 3, and a side has cylindrical protrusions to be used for connecting 4 connections of maintenance drive lead screw.During rotation adjustable lever 2, regulating block 3 is along adjustable lever 2 direction straight line motions, thereby crank radius changes.
Shown in the accompanying drawing 1, the present invention compares with common inline slidercrank mechanism has increased the adjusting parts, and it is by handwheel 8, hand wheel pole 11, and hand wheel pole cover 10, doubly apart from double thread screw drive link 6, gear 5,12 keeps drive lead screw 4 and regulates drive lead screw 7.Hand wheel pole cover 10 is fixed on the mainboard by flange, and offers the handwheel adjusting part and comprise handwheel 8, hand wheel pole 11, and gear 12 is along two positions of mainboard normal direction: i.e. working position shown in adjusted position shown in the accompanying drawing 3 and the accompanying drawing 4; Hand wheel pole (11) end has the certain projection of shape, and this projection matches with the adjusted position groove of regulating screw mandrel 2 ends; When the hand wheel pole assembly is positioned at adjusted position shown in the accompanying drawing 3, gear 12 and gear 5 engagements; The projection of hand wheel pole 11 ends combines with the adjusted position groove of regulating screw mandrel 2 ends; When the hand wheel pole assembly was positioned at working position shown in the accompanying drawing 4, gear 12 was thrown off with gear 5, and the projection of hand wheel pole 11 ends is thrown off with the adjusted position groove of regulating screw mandrel 2 ends.Be a hollow pipe apart from double thread screw drive link 6 doubly, the inwall at two ends has attacked tapped hole and direction is opposite, wherein near the pitch of crank one end be close slide block one end pitch 1/2nd, the outer wall in stage casing is milled with keyway, can be connected with gear 5 usefulness keys.Doubly the tapped hole apart from double thread screw drive link 6 two ends keeps drive lead screw 4 respectively and regulates drive lead screw 7 with being threaded.So just constitute one and regulated parts.
When the hand wheel pole assembly is positioned at adjusted position figure shown in the accompanying drawing 3, with handwheel 8 rotation hand wheel bars 11, to regulate screw mandrel 2 and rotate thereupon, the position of regulating block 3 changes, and crank length changes; Be positioned at gear 12 on the hand wheel pole 11 simultaneously and drive gear 5 rotations that are positioned at doubly on the double thread screw drive link 6, owing to keep the existence of drive lead screw 4, though therefore regulating block 3 drives and keeps drive lead screw 4 to make its position that variation take place, doubly the position apart from double thread screw drive link 6 and gear 5 still remains unchanged.Doubly the opposite side apart from double thread screw drive link 6 is connected with adjusting drive lead screw 7, the pitch at this place is reverse with maintenance drive lead screw 4 one sides for the twice and the screw thread that keep drive lead screw 4 one sides, therefore regulating block 3 increases synchronously or reduces to the length of relative distance between the slide block 13 and crank, reached thus when crank radius is adjusted, one end end points of slide block 13 movement locus remains unchanged, and to be benchmark with this end points increase or reduce the effect of the length that crank regulates in a side one-way synchronization.
