Embodiment
For being illustrated more clearly in the utility model, lift preferred embodiment and coordinate accompanying drawing to be described in detail as follows.
Referring to shown in Fig. 3 to Fig. 5, is the driving mechanism 100 of the intermittent movement of the utility model one preferred embodiment, and this driving mechanism 100 is applied to machining machine and tool, and it includes a rotating disc 10 and a camshaft 20.Wherein this rotating disc 10 is a disc-shaped bodies, in its card 12, is provided with a plurality of equally spaced contacts 14 along circumferencial direction, and respectively this contact 14 has a hemisphere portion 14a and is exposed to outside this card 12.In the present embodiment, respectively this contact 14 is placed in taking the kenel of a spherosome in the corresponding circular arc recess 16 of this rotating disc 10 as good.
This camshaft 20 of this driving mechanism 100 is arranged at the top of the card 12 of this rotating disc 10, and position place one side.This camshaft 20 includes a rotatingshaft 22 and a cam 24, and this rotatingshaft 22 arranges in the mode of parallel these rotating disc 10 cards 12, and this rotatingshaft 22 is subject to a power source (as motor) to order about rotation; This cam 24 is incorporated into the intermediate portion of this rotatingshaft 22, on this cam 24, be provided with a spiral chute 26, this cam 24 does not form a spiral helicine fin 28 for the part of these spiral chute 26 processes, and the bottom land of this spiral chute 26 coordinates the hemisphere portion 14a of this contact 14 and is curved surface.
As shown in Fig. 4 and Fig. 5, this spiral chute 26 of the present embodiment divides as battery limit (BL) and has an introduction segment 26a and to derive section 26b taking this fin 28, wherein the curved surface of the bottom land of this introduction segment 26a and this derivation section 26b is respectively the curved surface of 1/4 circle, and root edge to the height distance on these cam 24 surfaces of the bottom land of this introduction segment 26a and this derivation section 26b equates; Again, this introduction segment 26a curved surface towards with this derivation section 26b curved surface towards being to be outwardly and back to setting.The introduction segment 26a of said spiral groove 26 and the structure characteristic that derives section 26b, make this camshaft 20 in the time rotating, and can successfully this contact 14 be introduced in this spiral chute 26, then by this spiral helicine fin 28, these contact 14 pushing tows be derived.
This driving mechanism 100 of the present embodiment is in the time that the cam 24 of its camshaft 20 contacts and acts on the contact 14 of spherosome, because contact 14 is to contact with the curved surface bottom land of the hemisphere portion 14a of its first half and the spiral chute 26 of cam 24, and the recess 16 of the Lower Half of contact 14 and rotating disc 10 coordinates for circular arc, therefore be on average scattered in this contact 14 by making from the active force of this camshaft 20, in other words, the utility model solved known driving mechanism directly bear the lateral force of camshaft with cylindrical roller and have fail in shear form shortcoming, and then improve whole service life.
Secondly, the rotating disc 10 of this driving mechanism 100 is set as maintaining static conventionally, and taking control camshaft 20 near or the mode of leaving rotating disc 10 as.Therefore, in the time that respectively although this contact 14 occurs because long-term rolling has contacted abrasion situation with this cam 24, as long as adjust the shift motion of this camshaft 20 near rotating disc 10, clearance can diminish, and again guarantee there is good contact effect between each contact 14 of camshaft 20 and rotating disc 10, so that transmission process is smooth and easy.
In addition, on the cam 24 of this camshaft 20, can add an annular groove 29, this annular groove 29 is positioned at the bottom land of this spiral chute 26 and is all helical setting with this spiral chute 26 again.The effect of this annular groove 29 is to impel this contact 14 curved surface bottom land of this spiral chute 26 that more can fit perfectly.Also can avoid dust to build up in this place and affect the effect of connecting airtight to each other simultaneously.
If when the driving mechanism of above-described embodiment 100 is applied to the disc type tool magazine of vertical machining center, will be upright ornaments, and in order to stablize and to guarantee the respectively position of this contact 14, the driving mechanism of intermittent movement of the present utility model can suitably install a retainer additional.Wherein, in the embodiment shown in fig. 6, this cam 24 of this camshaft 20 has one first width W 1 in the axial direction, and this retainer is a top cover 30, this top cover 30 and the card 12 of this rotating disc 10 distance of being separated by, this distance is greater than the radius of the hemisphere portion 14a of this contact 14, so that the rotation of this rotating disc 10 is not interrupted; This top cover 30 separately has an opening 32, this opening 32 has the first width W 1 that one second width W 2 is not less than this cam 24, so that these opening 32 areas can be contained two contacts 14, so, other contacts 14 that do not contact for this cam 24 will be limited on this rotating disc 10 for this top cover 30.Another embodiment as shown in Figure 7, this retainer includes a plurality of stabilizing members 40, respectively this stabilizing member 40 utilizes locking mode and is fixedly arranged on this rotating disc 10, and respectively there are two arcuated fin pieces 42, utilize respectively this arcuated fin piece 42 to press close to the hemisphere portion 14a surface of the contact 14 of a correspondence, can reach the object of Restricted Contact part 14 positions.
The foregoing is only the better possible embodiments of the utility model, such as apply the equivalence variation that the utility model specification and claim are done, ought to be included in the scope of the claims of the present utility model.
