Abstract
The invention relates to a sine mechanism for movement of a crankshaft framework. The sine mechanism comprises two parallel guide pillars 1, a framework 2 which is assembled on the guide pillars, a slide block 3 which is arranged on the framework, a crankshaft 4 which is connected to the slide block and a drive wheel 5 which is fixedly connected to the crankshaft, wherein the drive wheel drives the crankshaft to rotate in a centred manner; the crankshaft rotating in the centred manner drives the slide block to be in a circular motion; and the circular motion drives the framework to be in a reciprocating straight-line motion along the guide pillars, so that the motion conversion from the circular motion to the reciprocating straight-line motion is achieved; the sine mechanism has relatively high mechanical efficiency and a relatively small size.
Description
[technical field]
The present invention relates to a kind of sine generator scotch yoke of bent axle frame movement.
[background technique]
Sine generator scotch yoke is that the rotation round movement conversion with input is the mechanism with specific linear reciprocating motion rule, and wherein said specific linear reciprocating motion rule is meant that the to-and-fro motion amplitude of mechanism output is the sine function of time.Sine generator scotch yoke becomes the core component of amplitude of vibration formula testing installation; Yet do not see as yet up to now the sine generator scotch yoke of high-speed and high-efficiency product is arranged; Thereby it can't obtain preferably practical applications widely always in testing installation, and the amplitude of vibration testing installation often adopts the reciprocating mechanism of the near sinusoidal characteristics of motion to replace.And there are defectives such as mechanical efficiency is low, shake is low, bulky frequently, mechanism's life-span is short in existing sine generator scotch yoke.
[summary of the invention]
Technological scheme to be solved by this invention is to provide a kind of sine generator scotch yoke of bent axle frame movement, and its mechanical efficiency is higher relatively, and volume is less relatively.
For realizing above-mentioned purpose; The present invention adopts following technological scheme: a kind of sine generator scotch yoke of bent axle frame movement; It is installed on the body; This sine generator scotch yoke comprises by two parallel guide pillars, be assembled in framework on the guide pillar, be installed in slide block on the framework, be connected in the bent axle of slide block and be fixed in the driving wheel of bent axle, and driving wheel drives bent axle and does the centering rotation, and the bent axle of centering rotation drives slide block and moves in a circle; This circular movement drives framework and does linear reciprocating motion along guide pillar, thereby realizes that circular movement converts the action conversion of linear reciprocating motion into.
Compared with prior art, mechanical efficiency of the present invention is higher relatively, and volume is less relatively.
[description of drawings]
Fig. 1 is an embodiment's of sine generator scotch yoke of the bent axle frame movement of the present invention schematic representation of Facad structure.
Fig. 2 is the side view of Fig. 1.
[embodiment]
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.
Ginseng Fig. 1 and shown in Figure 2; The sine generator scotch yoke 100 of bent axle frame movement of the present invention is installed on the body 101; This sine generator scotch yoke comprises by two parallel guide pillars 1, be assembled in framework 2 on the guide pillar, be installed in slide block 3 on the framework, be connected in the bent axle 4 of slide block and be fixed in the driving wheel 5 of bent axle; Driving wheel drives bent axle 4 and does the centering rotation; The bent axle 4 of centering rotation drives slide block 3 and moves in a circle, and this circular movement drives framework 2 and does linear reciprocating motion (being the A-A direction) along guide pillar 1, thereby realizes that circular movement converts the action conversion of linear reciprocating motion into.
Bent axle 4 is fixedly connected on driving wheel 5 through a bearing 41, and bent axle also is connected through bearing 41 with slide block 3, and slide block 3 is slidingly connected to framework, and framework 2 is slidingly connected to guide pillar 1.Framework 1 is provided with the circular hole (not label) of pair of parallel, and guide pillar 1 passes circular hole and makes framework move along the A-A direction straight line of guide pillar.Guide pillar is perpendicular to body 101, and slide block is done to do slip perpendicular to the direction of A-A on support, and promptly the linear reciprocating motion spare of framework is vertical each other with respect to the moving direction of slide block.The axle center of the axis deviation driving wheel of bent axle; When driving wheel was opened at motor 102, driving wheel drove bent axle 4 and rotate along track 51, and this track is that the axle center with live axle is the circumference (promptly feel relieved and rotate) in the center of circle; The slide block that is fixed on the bent axle axle center is driven by bent axle and makes circular movement along track 51; Because of fixing in the axle center of driving wheel, the circular movement in framework of slide block 3 makes framework on guide pillar, do straight reciprocating motion; This to-and-fro motion amplitude is the sine function of time, thereby realizes that circular movement converts the specific linear reciprocating motion amplitude locus with sinusoidal rule into.The track 51 of the centering rotation of bent axle does not exceed framework, thereby reduces overall volume.The present invention realizes that structurally volume is little, in light weight, driving force is big, thereby has improved running speed widely, has improved working efficiency; Prolonged the working life of mechanism.
