Description
Technical field
The utility model relates to a kind of drive unit, particularly a kind of linear drives swing angle device.
Background technique
In the industrial production, sometimes need to drive certain workpiece or instrument to make the change of corresponding angle, namely this workpiece is driven to swing on spatial position, and in the process driving workpiece to swing, the maximum problem run into is exactly that the angle swung is difficult to accurate control (namely kinematic accuracy is poor), so cause workpiece motion s not in place, be difficult to problem such as guarantee machining accuracy etc.
Summary of the invention
The utility model is the above-mentioned deficiency in order to solve existing for prior art, proposes one and by transform linear motion for swinging, and can accurately can control the linear drives swing angle device of pendulum angle.
Technical solution of the present utility model is: a kind of linear drives swing angle device, it is characterized in that: described swing angle device comprises fixing frame 1, fixing frame 1 is hinged with swing mechanism 2, swing mechanism 2 is fixedly installed a swing arm 3, one end of swing arm 3 is fixedly connected with the shell of drive motor 10, drive motor 10 drives leading screw 4 to rotate by coupling, the bottom of leading screw 4 is socketed with screw 5, screw 5 is outside equipped with nut seat 6, nut seat 6 is hinged with fixed arm 8 by two symmetrically arranged rotating shafts 7, fixed arm 8 is then fixedly connected with fixing frame 1, fixing frame 1 is also provided with the angular encoder 9 matched with swing mechanism 2.
Compared with the existing technology, tool has the following advantages the utility model:
The linear drives swing angle device of this kind of structural type, the mechanism kinematic low precision that it swings for traditional realization, cause workpiece motion s not in place, be difficult to ensure the problem such as machining accuracy, designing a kind of can be the structure swung by transform linear motion, because it can control the relation between the revolution of drive motor and the final angle swung accurately, therefore the accurate control of pendulum angle can be realized, and it is also designed with the angular encoder for wobble detection angle, further ensure the accuracy of pendulum angle.Therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the sectional view of drive part in the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As Fig. 1, shown in Fig. 2: a kind of linear drives swing angle device, it comprises a fixing frame 1, fixing frame 1 is hinged with swing mechanism 2, this swing mechanism 2 is fixedly installed a swing arm 3, one end of this swing arm 3 is fixedly connected with the shell of drive motor 10, drive motor 10 is then connected with leading screw 4 by a coupling, when drive motor 10 works, leading screw 4 can be driven to rotate, screw 5 is socketed with in the bottom of leading screw 4, screw 5 arranged outside has nut seat 6, nut seat 6 is hinged with fixed arm 8 by two symmetrically arranged rotating shafts 7, fixed arm 8 then with between fixing frame 1 is fixedly connected with, fixing frame 1 is also provided with the angular encoder 9 matched with swing mechanism 2.
The working procedure of the linear drives swing angle device of the utility model embodiment is as follows: when this device of needs drives certain workpiece to swing, first the fixing frame 1 of this device is connected on a fixing basic platform, then the bottom will the workpiece swung being needed to be connected to swing mechanism 2, drive motor 10 works, leading screw 4 is driven to rotate, due to leading screw 4 being socketed with screw 5, and screw 5 and nut seat 6 all swing and are connected on fixed arm 8, when relatively rotating between leading screw 4 and screw 5, screw 5 has the trend of the axial motion along leading screw 4, but because screw 5 and nut seat 6 are all hinged on fixed arm 8 by rotating shaft 7, that is screw 5 axially cannot move at leading screw 4, therefore this driving screw 5 can produce the component driving screw 5 and nut seat 6 to swing for axle does with rotating shaft 7 along the power of leading screw 4 axial motion, screw 5 swings relative to fixed arm 8, owing to being fixedly connected with between fixed arm 8 with fixing frame 1, therefore above-mentioned action finally achieves the swing of swing mechanism 2, while swing mechanism 2 swings, the angular encoder 9 matched with swing mechanism 2 can detect its angle value swung, and these data are sent in control system, whether the angle that control system swings according to this feedback wobble detection mechanism 2 reality is consistent with the angle that will swing, then control drive motor 10 as consistent to quit work, then continue to control drive motor 10 action as inconsistent, until reach the required angle swung.According to design, the relation between drive motor 10 revolution and swing mechanism 2 pendulum angle can be known accurately, according to this relation, just accurately can control the angle that swing mechanism 2 swings.
