Abstract
The invention discloses a single-chip groove type indexing cam mechanism. The single-chip groove type indexing cam mechanism comprises a cam body, a camshaft, a driven rotating plate, a driven rotating plate shaft, a roller and a connecting piece. The cam body comprises one cam only and is internally provided an approximately complete groove surrounding the cam body. The camshaft and the driven rotating plate shaft are parallelly arranged and separately connected with the cam body and the driven rotating plate through the connecting piece. When the driven rotating plate is in the indexing movement stage, in a part of process of the stage, any of all rollers uniformly distributed on the driven rotating plate is located in the groove and makes contact with the inner profile face and the outer profile face of the groove to enable the driven rotating plate to rotate; and in the other part of process, two rollers exist in the groove at the same time and make contact with the inner profile face and the outer profile face of the groove at the same time to enable the driven rotating plate to rotate. When the driven rotating plate is in the static stage, one roller in the groove makes contact with the inner profile face and the outer profile face of the groove to keep the driven rotating plate static. Through alternation of the two stages, the single-chip groove type indexing cam mechanism can realize the indexing movement, the structure is more reasonable, the existing parallel indexing cam processing detects can be avoided to a certain degree, and meanwhile the production cost is reduced.
Description
Technical field
The present invention relates to a kind of cam mechanism, more particularly to a kind of groove-shaped indexing cam mechanism of one chip.
Background technology
Parallel indexing cam mechanism is widely used in various semi-automatic, automations, and cam makees continuous constant velocity rotation,
Driven turntable makees interrupted division motion, and it has, and input and output axis is parallel, driving torque big, operate steadily, the good, cost of rigidity
It is low, easily fabricated, can little number of divisions the advantages of be driven.Existing parallel graduated cam mostly is two panels even three cam combinations and makes
With wherein a piece of cam promotes roller movement, other cam Lock positioning action.Under equal processing conditionss, multi-disc is convex
Machining accuracy problem is exaggerated when wheel is applied in combination.Meanwhile, the economy problems such as production cost, production efficiency, cost of transportation are deposited
Greatly improving space.
The content of the invention
It is an object of the invention to overcome existing parallel indexing cam mechanism problem present in production and processing, there is provided one
The groove-shaped indexing cam mechanism of one chip is planted, described cam body is the presence of a groove in one chip, cam body, is utilized
The inside and outside wall of groove plays promotion roller movement and locking positioning action, it is to avoid because multi-disc cam combination is used make processing essence
The drawbacks of degree problem is exaggerated, while reducing production cost.
To solve Problems Existing, one aspect of the present invention is to provide a kind of groove-shaped index cam of one chip
Mechanism, including cam body, camshaft, driven turntable, driven turntable axle, roller, connector, the cam body is only one
There is a near-complete groove around cam body, the camshaft and driven turntable in piece cam, and cam body
Axle is arranged in parallel, and is coupled with the cam body and the driven turntable by connector respectively.
When the driven turntable is in the dividing movement stage, the partial routine in the stage is to be distributed in the driven turntable
On whole rollers in any one roller contact with the inside and outside profile surface of groove so that the driven turntable enters in the groove
Row motion, another part process is the presence of two rollers in groove simultaneously, and the two rollers connect with the inside and outside profile surface of groove simultaneously
Touch so that the driven turntable is moved；And in the driven turntable quiescent phase, dependence is a roller in groove
Contact to keep the static of the driven turntable with the inside and outside profile surface of groove.
The invention has the beneficial effects as follows：At least one roller is in the groove any time on the driven turntable, when
When the camshaft is at the uniform velocity continuously rotated, the cam body is also carried out at the uniform velocity continuously rotating due to the effect of connector, in institute
State in groove in the presence of roller, the driven turntable and driven turntable axle synchronously make discontinuous dividing movement, described roller
Pass in and out in groove at groove opening, to realize the specific dividing movement of mechanism, and the structure is more reasonable, only a piece of cam is utilized
The inside and outside wall of groove plays promotion roller movement and locking positioning action, and overcome makes processing essence because multi-disc cam combination is used
The drawbacks of degree problem is exaggerated, while reducing production cost.
Description of the drawings
Technical scheme in order to be illustrated more clearly that the embodiment of the present invention, below will be to making needed for embodiment description
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for

Specific embodiment
Clear, complete description will be carried out to the technical scheme in the embodiment of the present invention below, it is clear that described enforcement
Example is only a part of embodiment of the present invention, rather than the embodiment of whole, and based on the embodiment in the present invention, this area is common
All other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model of present invention protection
Enclose.
Fig. 1 and Fig. 2 is referred to, the embodiment of the present invention includes：A kind of groove-shaped indexing cam mechanism of one chip, including cam
Body 1, camshaft 4, driven turntable 5, driven turntable axle 7, roller 6, connector 8 and 10, the cam body 1 is only a piece of convex
There is a near-complete groove 9 around cam body, the cam body 1 and the cam in wheel, and cam body
Axle 4 is coupled by connector 8, and the driven turntable 5 is coupled with the driven turntable axle 7 by connector 10, the camshaft 4
It is arranged in parallel with driven turntable axle 7, the grade central angle of the roller 6 is distributed on the driven turntable 5, and the groove outer wall 3 sets
There is opening 2 so that roller 6 is passed in and out, carry out the pre- dividing movement set.
When the driven turntable 5 is in the dividing movement stage, the partial routine in the stage is to be distributed in described driven turn
Any one roller 6 in whole rollers 6 on disk 5 is contacted so that described driven in groove with the inside and outside profile surface of groove
Rotating disk 5 is moved, and another part process is the presence of two rollers 6 in groove simultaneously, the two rollers 6 simultaneously with groove
