The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, an adjustable indexing mechanism with 180-degree dead time comprises an arc plate 1, a first rotating shaft 12, a second rotating shaft 13 and a third rotating shaft 6, wherein an inner arc surface of the arc plate 1 is slidably connected with a circular ring 15, a front surface of the circular ring 15 is fixedly connected with a gear ring 16, an outer part of the first rotating shaft 12 is fixedly connected with a first rectangular plate 17, a front bottom of the first rectangular plate 17 is rotatably connected with an inner gear 11, a front surface of the inner gear 11 is rotatably connected with a second rectangular plate 9, a front surface of the second rectangular plate 9 is rotatably connected with a third rectangular plate 4, a movable sleeve of the third rectangular plate 4 is movably sleeved outside the third rotating shaft 6, a front top of the third rectangular plate 4 is rotatably connected with a pawl 8, a fixed sleeve of the third rotating shaft 6 is provided with a ratchet 5, and an outer gear 14 is fixedly sleeved outside the second rotating shaft 13.

In this embodiment, the inner arc surface of the arc plate 1 is provided with a sliding groove, the outside of the ring 15 is provided with a sliding rail, and the sliding rail slides in the sliding groove.

In this embodiment, a plurality of first teeth are arranged on the outer array of the gear ring 16, a plurality of second teeth are arranged on the inner array of the gear ring 16, the first teeth are in meshing transmission with the outer gear 14, and the second teeth are in meshing transmission with the inner gear 11.

In this embodiment, the front surface of the internal gear 11 is fixedly connected with the first cylinder 2, and the movable sleeve of the second rectangular plate 9 is sleeved outside the first cylinder 2.

In this embodiment, the front surface of the second rectangular plate 9 is fixedly connected with the second cylinder 3, and the third rectangular plate 4 is movably sleeved outside the second cylinder 3.

In this embodiment, a first through hole is opened on the front surface of the top of the third rectangular plate 4, a third cylinder 7 is movably sleeved in the first through hole, a pawl 8 is fixedly connected to the outside of the cylinder 7, a second through hole is opened on the front surface of the first rectangular plate 17, a fourth rotating shaft 10 is movably sleeved in the second through hole, and a fixed sleeve of the inner gear 11 is arranged outside the fourth rotating shaft 10.

The working principle is that firstly, the second rotating shaft 13 is controlled to be fixed, so that the outer gear 14 is controlled to be fixed, so that the gear ring 16 is controlled to be fixed, then the third rotating shaft 10 is rotated, so that the inner gear 11 is driven to rotate around the first rotating shaft 12, the inner gear 11 is engaged with the second teeth inside the gear ring 16 to move, when the inner gear 11 rotates 180 degrees clockwise, the center of the first cylinder 2 moves to the position of the highest point of the straight line L, the moving track of the first cylinder 2 is the straight line L, at this time, the first cylinder 2 drives the second rectangular plate 9 to move upwards to the right, so that the third rectangular plate 4 is driven to rotate around the third rotating shaft 6, the pawl 8 moves to the right by the angular distance of the helical teeth outside the ratchet wheel 15, at this time, the first rotating shaft 12 rotates 180 degrees anticlockwise, the pawl 8 is indirectly driven to push the ratchet wheel 5 to rotate by the angular distance of the helical teeth around the third rotating shaft 6 anticlockwise, from the above, it can be seen that rotating the first rotating shaft 12 clockwise 180 degrees, rotating it counterclockwise 180 degrees, i.e. one cycle, so as to make the ratchet wheel 6 counterclockwise move by one angular distance of helical teeth, when it is desired to change the time of this cycle, it is necessary to control the second rotating shaft 13 to drive the external gear 14 to rotate, so as to make the gear ring 16 rotate, so as to change the time when the internal gear 11 reaches the top end of the straight line L, then control the gear ring 16 to stop moving through the external gear 14, then control the third rotating shaft 10 to drive the internal gear 11 to rotate reversely, so that the first cylinder 2 will be opposite to the initial position, so as to drive the pawl 8 to push the ratchet wheel 5 to rotate counterclockwise by one angular distance of helical teeth, in this process, there is a place to be attentively debugged, when the time when changing the time when the first cylinder 2 moves to the top end of the straight line L, the internal gear 10 may rotate many turns, however, it should be adjusted within these many circles that the pawl 8 will not push the ratchet 5 to rotate, that is, only once the first cylinder 2 is moved from the top of the straight line L to the bottom of the straight line L, the pawl 8 can be allowed to push the ratchet 5 to rotate by an angular distance of one helical tooth, and otherwise, as long as the first cylinder 2 is not moved from the bottom of the straight line L to the top of the straight line L, the pawl 8 will not be moved into the next helical tooth.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
