Abstract
The utility model discloses a rotation stepping mechanism. The rotation stepping mechanism aims to solve the problem that the rotation angle of a rotation stepping mechanism in the prior art cannot be easily adjusted. The rotation stepping mechanism comprises a crank and a driven wheel, wherein a first connection rod and a second connection rod are arranged between the crank and the driven wheel; one end of the first connection rod is hinged to one end of the crank; the other end of the first connection rod is hinged to one end of the second connection rod; one end, far away from the first connection rod, of the second connection rod rotates coaxially with the driven wheel; ratchets are arranged at the edge of the driven wheel; a pawl is arranged on the second connection rod and is meshed with the ratchets; the crank is provided with a plurality of hinge holes. The rotation stepping mechanism is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to machine tool technology field, is specifically related to a kind of revolution stepping mechanism.
Background technique
In machine tool rotary working table, commonly use rotation motion mechanism, what rotation motion mechanism was conventional is Geneva mechanism, but in actual use, Geneva mechanism remains in following deficiency: traverse is unadjustable, and angle of revolution is difficult for regulating, and the acceleration of sheave in the time of starting and stopping is large, there is impact, and along with the increase of rotating speed or the minimizing of sheave groove number and aggravate, therefore should not be used for high-speed motion, multiplexly realize the transposition campaign that does not need frequent regulating rotary parallactic angle degree.
Model utility content
The utility model is intended to provide a kind of revolution stepping mechanism, to solve the problem of turning round the difficult adjusting in stepping mechanism angle of revolution in prior art.
Revolution stepping mechanism in this programme, comprise crank and follower, between crank and follower, be provided with first connecting rod, second connecting rod, first connecting rod one end and crank one end are hinged, and the first connecting rod the other end and second connecting rod one end are hinged, and second connecting rod is away from one end and the follower coaxial rotation of first connecting rod, follower upper edge is provided with ratchet, second connecting rod is provided with ratchet, described ratchet and ratchet engagement, and crank is provided with multiple hinging holes.
Compared with prior art, the utility model has the advantages that: working state lower crank drives first connecting rod motion, first connecting rod drives second connecting rod to swing, thereby the ratchet engagement on the ratchet on second connecting rod and follower realizes follower revolution step motion, in addition, crank is provided with multiple hinging holes, just can change the length of crankweb by changing the articulated position of crank and first connecting rod, thereby adjust the size of angle of revolution, the utility model is simple in structure, processing ease, also can change angle of revolution.
Further, between described second connecting rod and ratchet, be provided with wind spring, make ratchet keep working position, prevent that ratchet from departing from follower.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the utility model revolution stepping mechanism embodiment's structural representation.
Embodiment
Shown in Fig. 1, revolution stepping mechanism in the utility model embodiment, comprise crank 1 and follower 2, between crank 1 and follower 2, be provided with first connecting rod 3, second connecting rod 4, first connecting rod 3 one end and crank 1 one end are hinged, first connecting rod 3 the other ends and second connecting rod 4 one end are hinged, second connecting rod 4 is away from one end and follower 2 coaxial rotation of first connecting rod 3, follower 2 upper edge are provided with ratchet, second connecting rod 4 is provided with ratchet 41, described ratchet 41 and ratchet engagement, crank 1 is provided with multiple hinging holes, between described second connecting rod 4 and ratchet 41, be provided with wind spring.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic is not done too much description at this.Should be understood that; for a person skilled in the art, not departing under the prerequisite of the utility model structure, can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
Claims (2)
