Abstract
The invention provides a cam stroke amplifying device which comprises a base. The base is further provided with a stroke amplifying mechanism which comprises a support fixed on the base, and the support is provided with a horizontal sliding rod and a fixed rack. A vertical rod is hinged to the horizontal sliding rod, a sector gear is fixedly connected to the bottom end of the vertical rod, and the sector gear is meshed with the rack. A backing pin is further fixedly arranged on the horizontal sliding rod, and the backing pin is in contact with the outer edge of a cam. When the cam is rotated, the outer edge of the cam is in contact with the backing pin, the horizontal sliding rod is driven to move horizontally, and the moving distance is the lift of the cam. The vertical rod with the sector gear is hinged to the horizontal siding rod, the sector gear is meshed with the fixed rack, so that moving of the horizontal sliding rod can drive the sector fan to swing, then the other end of the vertical rod with the sector gear is driven to swing, and the swing distance is the specific value of the vertical rod and the radius of the sector gear.
Description
Technical field
The present invention relates to a kind of mechanical device, be specifically related to a kind of amplifying device of cam stroke.
Background technique
Cam mechanism is a kind of common mechanism, and because the difficulty of processing of cam mechanism is low, and cam also has the feature of self-locking, widely applies among mechanical device.But due to the structural feature of cam self, in the time need to utilizing cam mechanism to attempt to obtain larger move distance, often need larger structure space, or need larger cam mechanism, this is difficult to accomplish in limited space.
Summary of the invention
The technical problem to be solved in the present invention be cam structure when obtaining larger move distance, often need larger structure space, be difficult to realize in limited space.
For achieving the above object, technological scheme of the present invention is: cam stroke amplifying device, comprise base, described base is provided with Cam rest, on described Cam rest, be hinged with the camshaft of level, described cam the tip of the axis is fixed with cam, on described base, be also provided with stroke amplifying mechanism, described stroke amplifying mechanism comprises the support being fixed on base, described support is provided with a horizontal sliding bar and a fixing tooth bar, a hinged montant on described horizontal sliding bar, the bottom of described montant is fixedly connected with a tooth sector, described fan tooth wheel and rack engagement, on described horizontal sliding bar, be also fixed with a backing pin, described backing pin contacts with the outer rim of cam.
While adopting technique scheme, during rotating cam, the outer rim of cam contact backing pin, drives horizontal sliding bar to move horizontally, and mobile distance is exactly the lift of cam.Add and on horizontal sliding bar, be hinged with the montant with tooth sector, tooth sector and the engagement of fixing tooth bar, therefore, the movement of horizontal sliding bar will drive the swing of tooth sector, and then causing that the other end with the montant of tooth sector swings, the distance of its swing is exactly the ratio of montant and tooth sector radius.
Further, the length of described montant and the radius ratio of tooth sector are 4:1.
Further, the length of described montant and the radius ratio of tooth sector are 5:1.
Further, in order to prevent that lever and cam Long Term Contact from causing wearing and tearing, is arranged with roll sleeve on described backing pin.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is cam stroke amplifying device embodiment's of the present invention structural representation.
Embodiment
As shown in Figure 1, cam stroke amplifying device of the present invention, comprises base 1, is fixed with Cam rest 2 on base 1, is hinged with the camshaft 21 of level on Cam rest 2, and the end of camshaft 21 is fixed with cam 22.On base 1, be also provided with stroke amplifying mechanism, the trip enlarger comprises the support 3 being fixed on base, a horizontal sliding bar 31 and a fixing tooth bar 32 are installed on support 3, a hinged montant 4 on horizontal sliding bar 31, a tooth sector 41 has been welded in the bottom of montant 4, this tooth sector 41 and tooth bar 32 engagements.On horizontal sliding bar 31, also welded a backing pin 42, backing pin 42 contacts with the outer rim of cam 22.
During use, during rotating cam 22, the outer rim of cam 22 contact backing pin 42, drives horizontal sliding bar 31 to move horizontally, and mobile distance is exactly the lift of cam 22.Add and on horizontal sliding bar 31, be hinged with the montant 4 with tooth sector 41, tooth sector 41 meshes with fixing tooth bar 32, therefore, the movement of horizontal sliding bar 31 will drive the swing of tooth sector 32, and then causing that the other end with the montant 4 of fan tooth 41 swings, the distance of its swing is exactly montant 4 and the ratio of tooth sector 41 radiuses.Can choose the length of montant 4 and the radius ratio of tooth sector 41 is 5:1 or 4:1.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; do not departing under the prerequisite of structure of the present invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
