Detailed Description

The utility model is further illustrated below with reference to the figures and examples.

As shown in figures 1 to 4, the self-locking pneumatic jacking device comprises a mounting plate 1, a connecting arm I5, a connecting arm II 6 and a connecting arm III 7. Install cylinder installing support 2 and supporting seat 4 in the one end of mounting panel 1, cylinder installing support 2 and supporting seat 4 are located mounting panel 1's both sides, and cylinder installing support 2 is used for articulated support cylinder 3, and supporting seat 4 is used for articulated support linking arm I5. Specifically, the cylinder mounting support 2 comprises a bottom plate II 2-1 and an L-shaped plate 2-2, the bottom plate II 2-1 is connected with the mounting plate 1 through bolts, one side plate of the L-shaped plate 2-2 is perpendicularly connected with the bottom plate II 2-1, the other side plate of the L-shaped plate 2-2 extends towards the outer side of the mounting plate 1, a hinge hole of the cylinder 3 is formed in the side plate of the L-shaped plate 2-2 extending towards the outer side of the mounting plate 1, and interference with the mounting plate 1 can be avoided after the cylinder bottom of the cylinder 3 is hinged with the L-shaped plate 2-2 of the structure. Linking arm I5 is V type structure, and cylinder 3's telescopic link is articulated with a free end of linking arm I5, and linking arm I5's V type bottom is articulated with supporting seat 4, specifically, supporting seat 4 includes bottom plate I4-1 and otic placode 4-2, two otic placode 4-2 sets up perpendicularly on bottom plate I4-1, bottom plate I4-1 and mounting panel 1 swing joint, and linking arm I5's V type bottom articulates two between otic placode 4-2. The other free end that cylinder 3 was kept away from to linking arm I5 is articulated with linking arm II 6, and linking arm II 6 is provided with two, and two linking arms II 6 articulate in the both sides of linking arm I5. One end, far away from the connecting arm I5, of the connecting arm II 6 is hinged to the connecting arm III 7, a guide seat 8 is further arranged on the mounting plate 1, one end, far away from the connecting arm II 6, of the connecting arm III 7 penetrates out of a guide hole of the guide seat 8, and a limiting bolt 11 movably connected with the mounting plate 1 is arranged below the hinged position of the connecting arm I5 and the connecting arm II 6; as shown in fig. 2 and 3, when the cylinder 3 extends to the end stroke, the connecting arm ii 6 is kept horizontal.

As shown in the figures 1 and 3, the air cylinder 3 is hinged to the connecting arm I5 through a hinge shaft I13, the bottom of the connecting arm I5 is hinged to the supporting seat 4 through a hinge shaft II 14, the connecting arm I5 is hinged to the connecting arm II 6 through a hinge shaft III 15, and the connecting arm II 6 is hinged to the connecting arm III 7 through a hinge shaft IV 16.

In the process that cylinder 3 is by the not stretching out state of fig. 1 to the stretching out state of fig. 2, stretching out of cylinder 3 drives linking arm I5 and rotates around articulated shaft II 14, and linking arm I5 then drives linking arm II 6 and does planar motion (including linking arm II 6 and the translation that linking arm II 6 promoted linking arm III 7 of rotating downwards around articulated shaft IV 16), and linking arm III 7 is pushed down at linking arm II 6 and is done rectilinear motion towards guide holder 8 direction. After the cylinder 3 reaches the end stroke, the connecting arm III 7 tightly pushes the workpiece, and the connecting arm II 6 is kept horizontal. The top of the limit bolt 11 is brought into contact with the connecting arm i 5 by adjusting the limit bolt 11 and the lock nut 12. Because the left sides of the connecting arm II 6, the connecting arm III 7 and the connecting arm I5 are positioned on the same straight line, when the connecting arm III 7 is subjected to thrust towards the direction of the connecting arm II 6, the thrust is completely converted into shearing force on the hinged shaft II 14, and torque capable of enabling the connecting arm I5 to surround the hinged shaft II 14 is not generated, so that the self-locking purpose is achieved.

As shown in fig. 1 to 4, one end of the connecting arm iii 7, which is far away from the connecting arm ii 6, penetrates out of the guide hole of the guide seat 8 and is movably connected with the adjusting joint 10. By adjusting the adjusting nut 9 and the adjusting joint 10, the precision of the position of the top tight end of the adjusting joint 10 can be ensured.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention in any way, and all simple modifications, equivalent variations and modifications made to the above embodiments according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
