Brief description of the drawings
Fig. 1 is positive structure diagram of the invention；
Fig. 2 is overlooking the structure diagram of the invention.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of fixture, including bottom plate 1, guide rail 2 and hold-down mechanism, guide rail 2 are respectively provided at bottom plate 1
Both sides, the hold-down mechanism includes support bar 3, cross bar 4 and leading screw 5, and the support bar 3 is located on guide rail 2, and cross bar 4 is fixed
Between supported on both sides bar 3, the centre position of cross bar 4 is drilled with a through hole, and leading screw 5 passes through through hole；Hand is socketed with leading screw 5
Wheel 6, the handwheel 6 is located at the top of cross bar 4, and rotation hand wheel 6 can control the lifting of leading screw 5；The end of leading screw 5 positioned at the lower section of cross bar 4
End is installed with sucker 7, and the sucker is Pneumatic suction cup, and sucker is provided with air valve switch.
The bottom of support bar 3 is inverted U-shaped base 8, the U-shaped width of inverted U-shaped base 8 is slightly larger than the width of guide rail 2, and support bar falls
U-shaped base 8 is nested with guide rail 2, and can be slided along guide rail.The dry inverted U-shaped base 8 of support passes through Y shape connecting rod 10 and cylinder
It is connected, two headtrees of Y shape connecting rod connect two inverted U-shaped bases, other end connection cylinder respectively.
Two alignment pins 9 are respectively equipped with two side rails, one of alignment pin is arranged on the centre position of guide rail, another
Individual alignment pin is arranged on the end of guide rail, and support bar is slided between two alignment pins.
The use process for the fixture that the present invention is provided is as follows：
Under original state, support bar 3 is centrally positioned at alignment pin；During using fixture, cylinder is opened, passes through Y shape connecting rod 10
Support bar 3 is promoted to be slid on guide rail 2 at end gage pin, rotation hand wheel 6 makes leading screw 5 drop to sucker 7 and touches workpiece
Surface, opens the air valve switch on Pneumatic suction cup, and sucker can hold workpiece, now reversely rotates handwheel 6, leading screw 5 is increased
Initial place plane is left to workpiece, support bar 3 is withdrawn at interfix pin by Y shape connecting rod 10.Rotate hand
Wheel 6, declines leading screw 5, and workpiece is placed with clamp bottom board 1, can now close air valve switch, handwheel is somewhat rotated again
6, make sucker workpiece pressing, other associative operations then are carried out to workpiece.After the completion of when needing transfer workpiece, then open air valve and open
Pass makes sucker hold workpiece, and rotation hand wheel 6 rises leading screw 5, opens cylinder and promotes support bar 3 to be moved at end gage pin,
The security plane of workpiece can be placed by reversely rotating handwheel 6 again and dropping to leading screw 5, close air valve, discharge workpiece.
Described above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
