Abstract
The utility model discloses a kind of groove-shaped indexing cam mechanism of one chip applying barrel shaped roller.The groove-shaped indexing cam mechanism of one chip of described application barrel shaped roller comprises cam body, camshaft, link, driven turntable, driven turntable axle, barrel shaped roller.Described camshaft and described driven turntable axle are arranged in parallel.Described cam body is only a slice cam, and in cam, an existence radial cross section is the groove of cydariform.Described groove outer wall is provided with opening and passes in and out for barrel shaped roller, the dividing movement reserved in advance.Because roller is cydariform, can to a certain extent enlarge active surface, reduce contact stress, and realize positive to a certain extent.By the way, the groove-shaped indexing cam mechanism of one chip of described application barrel shaped roller can realize dividing movement, and more reasonable structure.
Description
Technical field
The utility model relates to a kind of cam mechanism, particularly relates to a kind of groove-shaped indexing cam mechanism of one chip applying barrel shaped roller.
Background technique
The groove-shaped indexing cam mechanism of one chip, its cam body is only a slice cam, and there is a groove in cam, utilizes the inside and outside wall of groove to play and promotes roller movement and locking positioning action, can be applicable in various semi-automatic, automatic.Cam does continuous constant velocity rotation, and driven turntable does interrupted division motion, and it has input output axis being parallel, operates steadily, good rigidly, cost are low, be easy to manufacture, can the advantage such as little number of divisions transmission.The groove-shaped indexing cam mechanism of existing one chip many application cylindrical roller (barrel shaped roller is not applied in this mechanism), roller and groove two wall contact area are two straight lines, and now require very high to the axial restraint of driven turntable, if there is axial displacement in driven turntable in mechanical operation, two length of straigh line of contact area shorten, even there will be the situation that roller contacts with cam disengages, dividing movement cannot be proceeded, even occur production accident.
Summary of the invention
The purpose of this utility model is to overcome the groove-shaped indexing cam mechanism of existing one chip Problems existing in actual applications, a kind of groove-shaped indexing cam mechanism of one chip applying barrel shaped roller is provided, there is a radial cross section in described mechanism cam body is the groove of cydariform, described barrel shaped roller moves in cydariform groove, so both suitably can increase the contact area of roller and trench wall, reduce contact stress, utilize again the particularity of drum-like shaped, realize positive, even if connecting in mechanical operation between driven turntable with driven turntable axle goes wrong, also roller generation axial displacement can not be caused.
For solving Problems Existing, the technological scheme that the utility model adopts is to provide a kind of groove-shaped indexing cam mechanism of one chip applying barrel shaped roller, comprise cam body, camshaft, driven turntable, driven turntable axle, barrel shaped roller, link, described roller is cydariform, namely roller two ends section radius is less than section radius in the middle part of roller, described cam body is only a slice cam, and an existence radial cross section is the groove of cydariform in cam body, described cam body is connected by link with described camshaft, described driven turntable is connected by link with described driven turntable axle, described camshaft and driven turntable axle are arranged in parallel, the central angles such as described barrel shaped roller are distributed on described driven turntable.
Described groove outer wall is provided with opening and passes in and out for barrel shaped roller, the dividing movement reserved in advance.
The beneficial effects of the utility model are: when described camshaft rotates at the uniform velocity continuously, described cam body also rotates at the uniform velocity continuously due to the effect of link, because the moment on driven turntable keeps at least one barrel shaped roller to be in cydariform groove, in groove barrel shaped roller effect under, driven turntable and driven turntable axle synchronously make discontinuous dividing movement, described barrel shaped roller is in groove opening place turnover groove, to realize the specific dividing movement of mechanism, roller designs is the contact area that cydariform both suitably can increase roller and trench wall, reduce contact stress, utilize again the particularity of drum-like shaped, realize positive, even if connecting in mechanical operation between driven turntable with driven turntable axle goes wrong, also roller generation axial displacement can not be caused.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein: Fig. 1 is the structural representation of the utility model one preferred embodiment.
Fig. 2 is the plan view of the utility model one preferred embodiment.
Fig. 3 is the plan view of the utility model one preferred embodiment.
In accompanying drawing, the mark of each parts is as follows: 1 cam body 2 groove opening 3 groove outer wall 4 camshaft 5 driven turntable 6 barrel shaped roller 7 driven turntable axle 8 link (between 1 and 4) 9 groove 10 link (between 5 and 7).
Embodiment
Clear, complete description is carried out below by the technological scheme in the utility model embodiment; obviously; described embodiment is only a part of embodiment of the present utility model; instead of whole embodiments; based on the embodiment in the utility model; those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, Fig. 2 and Fig. 3, the utility model is embodiment comprise: a kind of groove-shaped indexing cam mechanism applying barrel shaped roller, comprise cam body 1, camshaft 4, link 8 and 10, driven turntable 5, driven turntable axle 7, barrel shaped roller 6, driving link and the cam body 1 of described cam mechanism are only a slice cam, a cydariform groove 9 is there is in described cam body, on described driven turntable, each barrel shaped roller 6 is for waiting central angle distribution, and described roller 6 is cydariform.
Described driven turntable 5 upper any time has at least a barrel shaped roller 6 to be in cydariform groove 9, when described camshaft 4 rotates at the uniform velocity continuously, described cam body 1 also rotates at the uniform velocity continuously due to the effect of link 8, in described groove barrel shaped roller 6 effect under, described driven turntable 5 and driven turntable axle 7 synchronously make discontinuous dividing movement.
Described groove outer wall 3 is incomplete, and it is provided with opening 2 at suitable place and passes in and out for barrel shaped roller 6, the dividing movement reserved in advance.
