Abstract
The utility model discloses a kind of new type of cam rotating disk mechanism, belong to field of mechanical technique.Described motor output shaft and planetary reducer input axis connection, described planetary reducer output end is connected with cam worm-drive, cam path is provided with described cam worm screw, described cam worm screw side is provided with index dial, bearing is provided with described index dial, described bearing is of coupled connections with cam path, it is reasonable in design, employ Worm Wheel System principle, special worm screw flute profile may insure that bearing keeps being in close contact at any time, because bearing is pure rolling pattern in cam path, reduce the friction with groove face, with longer service life, bearing is to be threadedly coupled with rotating disk, bearing is not strict with radial height, it can be coupled well with cam path, and it is very convenient to, due to minimum frictional resistance, the high speed rotation of index dial can be realized, further improve service efficiency.
Description
Technical field：
A kind of new type of cam rotating disk mechanism is the utility model is related to, belongs to field of mechanical technique.
Background technology：
Geneva mechanism is the periodic intermittent motion for the uniform motion of driving shaft being converted to driven shaft, is usually used in indexing and turns
In the mechanism of position, this mechanism is used in traditional tool magazine mostly.The mechanism mainly includes active bent axle, sheave, finger and lock plate,
During work, active crank up axis is parallel with sheave axis of rotation, makees constant speed revolution, when the finger on active bent axle enters groove
In, just stir sheave and make reverse indexing campaign, when finger is deviate from from groove, sheave is transfixion and positioned by lock plate.
But although this mechanism can realize the intermittent movement of sheave, the cooperation of finger and groove requires very high, gap
Easily cause greatly very much in sheave operation and produce vibration, finger interference and collision easily occurs when passing in and out notch, so to driving crank
Rotating accuracy require higher, because finger and groove be point-like contacts, it is impossible to stably to rest on a position motionless, so must
Sheave could must be fixed by lock plate.
Utility model content：
In view of the above-mentioned problems, the technical problems to be solved in the utility model is to provide a kind of new type of cam rotating disk mechanism.
Cam turntable mechanism of the present utility model, it include motor, planetary reducer, cam worm screw, cam path, bearing and
Index dial, described motor output shaft and planetary reducer input axis connection, described planetary reducer output end and cam snail
Bar is connected, and is provided with cam path on described cam worm screw, described cam worm screw side is provided with index dial, described
Bearing is provided with index dial, described bearing is of coupled connections with cam path.
Preferably, described bearing is threadedly coupled with index dial.
Preferably, described bearing is strap bolt shaft roller needle bearing.
The beneficial effects of the utility model：Its structure is simple, reasonable in design, employs Worm Wheel System principle, special
Different worm screw flute profile may insure that bearing keeps being in close contact at any time, because bearing is pure rolling pattern in cam path, reduce
Friction with groove face, there is longer service life, bearing is with rotating disk be threadedly coupled, and bearing is in radial height without sternly
Lattice requirement, can be coupled with cam path well, and is very convenient to, due to minimum frictional resistance, it is possible to achieve point
The high speed rotation of scale, further improves service efficiency.
Brief description of the drawings：
For ease of explanation, the utility model is described in detail by following specific implementations and accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Reference：Motor 1, planetary reducer 2, cam worm screw 3, cam path 4, bearing 5, index dial 6.
Embodiment：
As shown in figure 1, present embodiment uses following technical scheme：It includes motor 1, planetary reducer 2, cam
Worm screw 3, cam path 4, bearing 5 and index dial 6, the described output shaft of motor 1 inputs axis connection with planetary reducer 2, described
The output end of planetary reducer 2 is connected with cam worm screw 3, and cam path 4 is provided with described cam worm screw 3, and described is convex
The side of worm and gear 3 is provided with index dial 6, and bearing 5 is provided with described index dial 6, and described bearing 5 is strap bolt shaft roller
Needle bearing, described bearing 5 are threadedly coupled with index dial 6, replacing easy to disassemble, described bearing 5 and the company of coupling of cam path 4
Connect.
Present embodiment operation principle is：Cam worm screw 3 is at the uniform velocity rotated by planetary reducer 2 with action, cam snail
Cam path 4 on bar 3 is cylindrical is fitted close with bearing 5, and its spiral lift is exactly the arc length that two bearings 5 rotate, when first
After individual bearing 5 enters helix, as cam worm screw 3 rotates, bearing 5 is slided up to departing from cam path 4 along cam path 4, convex
Worm and gear 3 rotates a circle, and a bearing 5 completes a displacement, i.e. index dial 6 completes a step motion.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
