Abstract
The invention discloses a screw rod device of an anti-lock precision workbench. The screw rod device comprises a ball screw, two driving blocks, two connecting pins and a connecting block. The two driving blocks are L-shaped. The ball screw vertically penetrates through one side plate of a first driving block, and the side block of the first driving block is fixed with a screw rod nut arranged on the ball screw. The other side plate of the first driving block is connected with the connecting block through a first connecting pin. The connecting block is arranged on the ball screw. The upper end of the connecting block is connected with one side plate of a second driving block through a second connecting pin. The other side plate of the second driving block is connected with a workbench. By the adoption of the technical scheme of the screw rod device, anti-lock screw rod deformation locking can be prevented, screw rod friction force is reduced, the service life of a screw rod is prolonged, and the cost of the device is low.
Description
Technical field
The present invention relates to the precision positioning research field, be specifically related to a kind of anti-lock precision stage feed screw apparatus.
Background technology
In the precise positioning work table field, by leading screw, drive in the driving mechanism of workbench, on the connected mode of feed screw nut and workbench, because driving moment is little, usually feed screw nut and workbench directly connect or between only be provided with simple maintainance block, but because the axis of feed screw nut is not fully parallel with workbench, also there is certain angle with horizontal plane, workbench will transmit a vertical component to leading screw by feed screw nut, cause leading screw top and bottom unbalance stress, in driving force hour, the impact of this situation is very little, want large many but now the driving force ratio of the large stroke precision positioning table of development is original, if the mechanism before also continuing to use, due to leading screw bearing up-down force inequality, can cause the leading screw bending, the situation of locking even.
Summary of the invention
The object of the invention is to overcome the problem that prior art exists, a kind of anti-lock precision stage feed screw apparatus is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of anti-lock precision stage feed screw apparatus, comprise ball-screw, the first drive block, the second drive block, the first connecting pin, the second connecting pin and a contiguous block, described the first drive block and the second drive block are L shaped, described ball-screw vertically passes the side plate of described the first drive block, and the side plate of described the first drive block fixes with the feed screw nut be arranged on described ball-screw, another side plate of described the first drive block is connected with described contiguous block by described the first connecting pin, described contiguous block is arranged on described ball-screw, described contiguous block upper end is connected with the side plate of described second drive block of top by described the second connecting pin, another side plate connecting working table of described the second drive block.
Further, the axis of the axis of described the first connecting pin and described the second connecting pin is perpendicular.
The invention has the beneficial effects as follows:
Adopt technical solution of the present invention, can prevent leading screw distortion locking, reduce leading screw frictional force, increase leading screw service life, and installation cost is very low.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Number in the figure explanation: 1, ball-screw, the 2, first drive block, the 3, second drive block, the 4, first connecting pin, the 5, second connecting pin, 6, contiguous block, 7, feed screw nut, 8, workbench.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Shown in Fig. 1, a kind of anti-lock precision stage feed screw apparatus, comprise ball-screw 1, the first drive block 2, the second drive block 3, the first connecting pin 4, the second connecting pin 5 and a contiguous block 6, described the first drive block 2 and the second drive block 3 are L shaped, the vertical side plate through described the first drive block 2 of described ball-screw 1, and the side plate of described the first drive block 2 fixes with the feed screw nut 7 be arranged on described ball-screw 1, another side plate of described the first drive block 2 is connected with described contiguous block 6 by described the first connecting pin 4, described contiguous block 6 is arranged on described ball-screw 1, described contiguous block 6 upper ends are connected with the side plate of described second drive block 3 of top by described the second connecting pin 5, another side plate connecting working table 8 of described the second drive block 3.
Further, the axis of the axis of described the first connecting pin 4 and described the second connecting pin 5 is perpendicular.
Principle of the present invention:
When ball-screw 1 motion, feed screw nut 7 drives the first drive block 2 motions, the first drive block 2 matches with the first connecting pin 4, drive contiguous block 6 to move together, contiguous block 6 matches with the second connecting pin 5 again, drive the second drive block 3 to move together, the second drive block 3 drives workbench 8 again and carries out running fix.The component that utilizes structure that the transition of two drive blocks drives effectively to offset all directions.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
