Abstract
The invention discloses a variable-speed swing device to solve the problem that in the prior art, the rotation angle of an existing rotation mechanism is not easy to adjust. The variable-speed swing device comprises a machine frame, a driving shaft arranged on the machine frame, a rack fixed to the driving shaft, a sector gear meshed with the rack, a sliding pin arranged on the edge of the sector gear, and a swing arm with one end hinged to the machine frame, wherein a slide groove where the sliding pin can slide is formed in the middle of the swing arm, a first limiting switch and a second limiting switch are arranged on the two sides of the sector gear on the machine frame, and a plurality of hinge holes are formed in the machine frame. The variable-speed swing device is simple in structure and high in efficiency.
Description
Technical field
The present invention relates to to-and-fro motion technical field, be specifically related to a kind of speed change oscillator device.
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 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 speed change oscillator device, to solve swirl gear angle of revolution in prior art, be difficult for the problem regulating.
Speed change oscillator device in this programme, comprise frame, also comprise tooth bar that push rod, push rod drive, be hinged on the swing arm in frame with tooth sector, the sliding pin that is located at tooth sector edge and one end of tooth bar engagement, swing arm middle part is provided with the chute that can slide for sliding pin, tooth sector and frame are rotationally connected, in frame, tooth sector both sides are provided with the first limit switch, the second limit switch, and frame is provided with a plurality of hinging holes.
Compared with prior art, advantage of the present invention is: under working state, push rod band carry-over bar forward slides, tooth bar and tooth sector engagement, tooth sector forward rotation also drives swing arm to swing by sliding pin, because sliding pin velocity magnitude is constant, and sliding pin moves in swing arm chute, so swing arm variable Rate swings, tooth sector triggers after the first limit switch, push rod reversing motion, by rack drives tooth sector, reverse, tooth sector drives swing arm variable Rate to swing by sliding pin, tooth sector triggers after the second limit switch, tooth bar again forward slides, so move in circles, realize the to-and-fro motion of variable Rate, in addition by changing the articulated position of swing arm and frame with regard to the size of capable of regulating angle of revolution, the present invention is simple in structure, processing ease, rate-compatible, also can change angle of revolution.
Further, sliding pin threaded one end is connected with anti-drop block, and anti-skidding pin departs from.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is speed change oscillator device embodiment's of the present invention structural representation.
Embodiment
Shown in Fig. 1, speed change oscillator device in the embodiment of the present invention, comprise frame, also comprise tooth bar 1 that push rod, push rod drive, be hinged on the swing arm 3 in frame with tooth sector 2, the sliding pin that is located at tooth sector 2 edges and one end of tooth bar 1 engagement, swing arm 3 middle parts are provided with the chute that can slide for sliding pin, tooth sector 2 is rotationally connected with frame, in frame, tooth sector 2 both sides are provided with the first limit switch 41, the second limit switch 42, frame is provided with five hinging holes, and sliding pin threaded one end is connected with anti-drop block.
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.
