Description
Technical field
The utility model is related to mechanical transmission mechanism, more particularly to a kind of stepless indexing mechanism of mechanical double-way.
Background technology
Indexing mechanism is usually used in processing in the multiple holes being uniformly distributed along the circumference or groove and various clampings, and currently conventional is mechanical
Intermittent motion mechanism being used indexing mechanism, such as ratchet mechanism, Geneva mechanism, incomplete gear mechanism, pin wheel gear, indexing are convex more
Mechanism etc. is taken turns, wherein be most widely used with cam mechanism again, is primarily due to that cam type intermittent drive mechanism is simple in construction, energy
It is automatically positioned, the output ratio of Q-switching to free running can be selected arbitrarily, but the indexing feature of cam-type indexing mechanism is：The power of mechanism is input axial direction
Rotation, input shaft rotates a circle, and output shaft realizes a dividing movement, and indexing angle is determined according to station number, can only
Realize single direction rotary index.
Utility model content
The applicant is directed to disadvantage mentioned above, and having carried out Improvement, there is provided a kind of stepless indexing mechanism of mechanical double-way.
The technical scheme that the utility model is used is as follows：
A kind of stepless indexing mechanism of mechanical double-way, including index dial, indexing bevel gear, the index dial and pitch cone tooth
Wheel is connected by the first connecting shaft, and the indexing bevel gear both sides symmetrically connect drive device, and the drive device includes second
Connecting shaft, driving bevel gear, roller gear and rack, the driving bevel gear are fixed on the second connection shaft end, and driving cone
Gear and indexing bevel gear engagement, the roller gear are connected in the middle part of the second connecting shaft by unilateral bearing, and the rack is set
Put in roller gear side, rack lower end connection back-moving spring, the drive division of the rack upper end connection driving upper and lower motion of rack
Part.
It is used as the further improvement of above-mentioned technical proposal：
The roller gear is interference fitted with unilateral bearing outer ring, and unilateral bearing inner ring and the second connecting shaft are interference fitted.
The beneficial effects of the utility model are as follows：The stepless indexing mechanism of mechanical double-way, meeting index dial can
It is stepless to rotate, and the multifarious needs of Double-directional rotary can be come and gone.
Brief description of the drawings
Fig. 1 for the stepless indexing mechanism of mechanical double-way that the utility model is provided structural representation.
In figure：1st, index dial；2nd, bevel gear is indexed；3rd, the first connecting shaft；4th, the second connecting shaft；5th, driving bevel gear；6、
Roller gear；7th, rack；8th, unilateral bearing；9th, back-moving spring.
Embodiment
Below in conjunction with the accompanying drawings, embodiment of the present utility model is illustrated.
As shown in figure 1, the stepless indexing mechanism of the mechanical double-way of the present embodiment, including index dial 1, indexing bevel gear 2, point
Scale 1 is connected with indexing bevel gear 2 by the first connecting shaft 3, and indexing bevel gear 2 both sides symmetrically connect drive device, driving dress
Put including the second connecting shaft 4, driving bevel gear 5, roller gear 6 and rack 7, driving bevel gear 5 is fixed on the end of the second connecting shaft 4
Portion, and driving bevel gear 5 and indexing bevel gear 2 engage, roller gear 6 is connected in the second connecting shaft 4 by unilateral bearing 8
Portion, and roller gear 6 and the outer ring of unilateral bearing 8 interference fit, the inner ring of unilateral bearing 8 are interference fitted with the second connecting shaft 4, rack
7 are arranged on the side of roller gear 6, and the lower end of rack 7 connection back-moving spring 9, the upper end of rack 7 connection drives the upper and lower motion of rack 7
Driving part.
The stepless indexing mechanism of mechanical double-way in use, when index dial 1 counterclockwise index when, the drive device in left side
Start, drive rack 7 to move along a straight line downwards by driving part, and compression reseting spring 9,6 turns of the roller gear of drive of rack 7
It is dynamic, while roller gear 6 drives 5 turns of the driving bevel gear that the second connecting shaft 4 and the second connecting shaft 4 are connected by unilateral bearing 8
Dynamic, driving bevel gear 5 drives indexing bevel gear 2 to rotate, and indexing bevel gear 2 drives index dial 1 counterclockwise by the first connecting shaft 3
Rotate, when the driving force of driving part is removed, back-moving spring 9 resets with carry-over bar 7, rack 7 drives roller gear 6 to rotate,
The outer ring of unilateral bearing 8 is also and then rotated, but inner ring is not rotated, then the second connecting shaft 4 is not also rotated, by controlling rack 7 downward
Stroke, the sub-degree angle of index dial 1 can be controlled, realize index dial 1 counterclockwise stepless indexing；When the clockwise index of index dial 1
When, the drive device on right side starts, and driving process is consistent with the drive device driving process in left side, realizes that index dial 1 is clockwise
Stepless indexing.
Above description is explained of the present utility model, is not the restriction to utility model, what the utility model was limited
Scope is referring to claim, and in the case of without prejudice to basic structure of the present utility model, the utility model can make any shape
The modification of formula.
