The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in Figures 1 to 4, this two-in-one mill comprises with drive unit:
The rotating shaft 1 of drive being rotated by external force, is arranged with in this rotating shaft for driving the first driving gear 2 of the first grinding head assembly (not shown) and for driving the second driving gear 3 of the second grinding head assembly (not shown).The first driving gear 2 is positioned at the top of the second driving gear 3.
The end face of the present embodiment shaft 1 is provided with groove 11; In groove, be provided with elastic component 6.The present embodiment Elastic part is flexible silica gel part, for the suitable column structure of groove; Between elastic component and groove perisporium, interval is gapped.
Position with respect to the first driving gear 2 and the second driving gear 3 on the sidewall of groove 11 is provided with perforation 12.In the present embodiment, be a perforation, convenient manufacture and assembling.Also perforation 12 can be divided into two arranges respectively.
The first projection 4 and the second projection 5 wear in perforation 12, and the first projection 4 is positioned at the top of the second projection 5.The second projection 5 is identical with the structure of the first projection 4.Take the structure of the first projection 4 two projections in example explanation the present embodiment.
The head of the first projection is wedge structure, exposes to perforation 12, and in the present embodiment, the head 41 of the first projection is ladder structure of right angle roughly.The root 42 of the first projection is conflicted on elastic component 6 through perforation 12; The root of the first projection is the arcuate structure suitable with the perisporium of elastic component, and the area of root is greater than the area of the head connecing in contrast, so that the first projection 4 can be fine the be fitted on elastic component.
In the present embodiment, the Yu Gai inclined-plane, inclined-plane of the first projection head and the tangent plane of the rotating shaft of position described in rotating shaft intersecting lens become 15 ° of angles; Angle after inclined-plane and tangent plane intersect can at 0-60 °.
The second projection 5 and the first projection 4 oppositely arrange.
The head of the first projection and the second projection can be also other structure, but at least have, become the first surface of 90 ± 30 ° of angles and second with the tangent line of corresponding position in rotating shaft, described second becomes 0-60 ° of angle with the tangent plane of described rotating shaft intersection location with described second;
On the internal perisporium of the first driving gear 2 and the second driving gear 3, be respectively equipped with first Slave Block 21 corresponding with the first projection 4 and the second projection 5 and the second Slave Block 31.The first Slave Block 21 and the second Slave Block 31 are the wedge structure suitable with the head of two projections, and both oppositely arrange.
In the present embodiment, the first driving gear meshes the first driven gear 7, the first driven gears 7 and drives the first grinding head assembly work; The second driving gear meshes the second driven gear 8, the second driven gears 8 and drives the second grinding head assembly work.
This two-in-one mill is described below by the operation principle of drive unit:
When rotating shaft forward, when going to the vertical plane of the first projection and the vertical plane of the first Slave Block and offset, the conflict by the first projection to the first Slave Block, makes the first driving gear rotate with rotating shaft; In forward process, when the second projection touches the second Slave Block, the second projection groove direction to rotating shaft under the touching of the second Slave Block is moved, promote and compression elastic piece, the second projection moves in groove, thereby dodges out the second Slave Block, makes the second projection along smooth and easy the slipping in inclined-plane of the second Slave Block, both frictions are very little, and the inclined-plane of the second projection and the second Slave Block is not wearing and tearing almost.
When second mill when work of needs, by rotating shaft upset, now contrary when the rotation direction of the first projection and the first Slave Block, the second projection and the second Slave Block and forward.
This two-in-one mill can make different mills work with drive unit by simply rotating and reverse, not only easy to operate, transmission accurate, stable, simple and compact for structure, take up room little, and rapid operation, long service life, can improve more comfortable and better feel, to learn exactly the duty of mill.
