Compared with prior art, the utility model parallel manipulator can be avoided manipulator fixture to move up and down in process offseting, thus ensures the positional precision of manipulator conveying object.
By following description also by reference to the accompanying drawings, the utility model will become more clear, and these accompanying drawings are for explaining embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structure chart of the utility model parallel manipulator angle.
Fig. 2 is the structure chart of another angle of the utility model parallel manipulator.
Detailed description of the invention
With reference to figure 1 and Fig. 2, the utility model parallel manipulator 100 comprises base 10, motor 20, connects screwed pipe 30, connecting screw rod 40, manipulator base 50, manipulator fixture 60 and three connecting rod attitude reference devices 70.
Described base 10 offers motor installing hole 11.Described motor 20 is installed on the bottom of described base 10 and the output shaft of described motor 20 protrudes upward described motor installing hole 11 connects with the described lower end being connected screwed pipe 30.The lower end of described connecting screw rod 40 screws the upper end being plugged in described connection screwed pipe 30.Described manipulator base 50 has evenly outwards protruded out three manipulator connecting portions 51.The upper end of described connecting screw rod 40 is fixed in the bottom of described manipulator base 50, and described manipulator fixture 60 is installed on the top of described manipulator base 50.The upper end of described connecting rod attitude reference device 70 rotates with corresponding manipulator connecting portion 51 and connects, and the lower end of described connecting rod attitude reference device 70 is installed on described base 10.
Particularly, described connecting rod attitude reference device 70 comprises and connects end cylinder 71, first connecting rod 72 and two second connecting rods 73.Cylinder 71 at the bottom of described connection is installed on described base 10, one end of described first connecting rod 72 is rotatably connected one end of at the bottom of described connection cylinder 71, the lower end of described second connecting rod 72 is rotatably connected in the both sides of the upper end of described first connecting rod 72 respectively, and the upper end of described second connecting rod 72 is rotatably connected respectively in the both sides of the described manipulator connecting portion 51 of correspondence.
Preferably, described parallel manipulator 100 also comprises lower rotary connection structure 80 and upper rotary connection structure 90.Described lower rotary connection structure 80 comprises contiguous block 82 on the first lower connecting block 81 and first, and the lower end of described first lower connecting block 81 connects with the output shaft of described motor 20.On described first, the lower end vertical rotary of contiguous block 82 is connected to the upper end of described first lower connecting block 81.On described first, the upper end of contiguous block 82 connects with the described lower end being connected screwed pipe 30; Described upper rotary connection structure 90 comprises contiguous block 92 on the second lower connecting block 91 and second.The lower end of described second lower connecting block 91 connects with the upper end of described connecting screw rod 40, on described second, the lower end vertical rotary of contiguous block 92 is connected to the upper end of described second lower connecting block 91, the upper end of contiguous block 92 and the bottom connection of described manipulator base 50 on described second.
When the utility model parallel manipulator 100 uses, motor 20 is with the screwed pipe 30 that is dynamically connected to rotate, connect screwed pipe 30 and connecting screw rod 40 to do and relatively screw motion, thus drive connecting screw rod 40 move up and down so that driving mechanical at hand seat 50 and manipulator fixture 60 move up and down, and connecting rod attitude reference device 70 is evenly connected on manipulator connecting portion 51, thus ensure that manipulator base 50 and manipulator fixture 60 move up and down in process and can not offset.
