Abstract
The invention discloses a one-way rotating mechanism to solve the problem that in the prior art, an existing machine tool rotating mechanism can not move in a single direction. The one-way rotating mechanism comprises a machine frame, a hydraulic cylinder arranged on the machine frame, a driven shaft connected with the machine frame in a rotating mode, a driven wheel fixed to the driven shaft, and a sliding rod, and further comprises a push rod and a sector gear which is connected with the driven shaft through a one-way bearing, a plurality of hinge joint holes are formed in the push rod, one end of the push rod is hinged to the rim of the hydraulic cylinder, the other end of the push rod is hinged to the sliding rod which can move in the axial direction, the two ends of the sliding rod are connected with the machine frame in a sliding mode, a section of rack is arranged in the middle of the sliding rod, the rack is meshed with the sector gear, and a first limiting switch and a second limiting switch are arranged at the positions, close to the sector gear, of the machine frame. The one-way rotating mechanism is simple in structure and high in practicability.
Description
Technical field
The present invention relates to machine tooling technical field, be specifically related to a kind of unidirectional rotary mechanism.
Background technology
In machine tool rotary working table, commonly use gyration mechanism, what gyration mechanism was conventional is Geneva mechanism, but in actual use, Geneva mechanism remains in certain weak point, traverse is unadjustable, corner can not be too little, cannot realize one-way movement, and the acceleration of sheave when 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 for high-speed motion, multiplexly realize the transposition campaign that does not need frequent regulating rotary parallactic angle degree.
Summary of the invention
The invention is intended to provide a kind of unidirectional rotary mechanism, to solve machine tool rotary motion in prior art, cannot realize the problem of one-way movement.
Unidirectional rotary mechanism in this programme, comprise frame, be located at the hydraulic cylinder in frame, the driven shaft being rotationally connected with frame and with the fixing driven pulley of driven shaft, also comprise the push rod being connected with hydraulic cylinder, the sector gear being connected by unilateral bearing with driven shaft and sliding bar, push rod is provided with a plurality of hinge holes, push rod one end jointed shaft is to sliding bar movably, sliding bar two ends and frame are slidably connected, sliding bar middle part is provided with one section of tooth bar, described tooth bar and the engagement of described sector gear, in frame, near sector gear place, be provided with the first limit switch, the second limit switch.
Compared with prior art, advantage of the present invention is: push rod positive movement, drive sliding bar moves back and forth, when sliding bar forward slides, rack drives sector gear forward on sliding bar, by individual event bearing, drive driven shaft forward, and then drive driven pulley forward, sector gear forward triggers after the first limit switch, push rod counter motion, sliding bar reverse slide, rack drives sector gear reversion on sliding bar, and individual event bearing can only be towards a direction motion, thereby sector gear idle running, driven pulley cannot rotate with sector gear, sector gear reversion triggers after the second limit switch, push rod is positive movement again, so just realized the unidirectional rotary motion of driven pulley, in addition, push rod is provided with a plurality of hinge holes, can regulate sliding bar sliding position, changes sector gear hunting range, and the present invention is simple in structure, processing ease.
Further, frame and the sliding bar place of being slidably connected are provided with abrasive rubber cover, avoid the direct contact wear of sliding bar and frame.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of unidirectional rotary mechanism for implementing example of the present invention.
The specific embodiment
Shown in Fig. 1, unidirectional rotary mechanism in the present embodiment, comprise frame, be located at the hydraulic cylinder 1 in frame, the driven shaft 5 being rotationally connected with frame and with the fixing driven pulley 4 of driven shaft 5, also comprise the push rod 2 being connected with hydraulic cylinder 1, the sector gear being connected by unilateral bearing with driven shaft 5 and sliding bar 3, push rod 2 is provided with three hinge holes, push rod 2 one end jointed shafts are to sliding bar 3 movably, sliding bar 3 two ends and frame are slidably connected, sliding bar 3 middle parts are provided with one section of tooth bar, described tooth bar and the engagement of described sector gear, in frame, near sector gear place, be provided with the first limit switch 61, the second limit switch 62, frame and sliding bar 3 places of being slidably connected are provided with abrasive rubber cover.
Above-described is only embodiments of the invention, 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 structure of the present invention, can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
