Detailed description of the invention

Hereinafter, with embodiment, the utility model is described in detail referring to the drawings:

As it is shown in figure 1, a kind of aluminium section processing uses anti-back clamping device, including cylinder 1, at described cylinder 1 outer wall Being provided with multiple telescopic arm 2, described telescopic arm 2 is provided with clamp jaw 3, described clamp jaw 3 includes being connected with telescopic arm 2 Fixed plate 4, gripping No. I clamping plate 5 of aluminium section and No. II clamping plate 6, described No. I clamping plate 5 by connecting plate with Fixed plate 4 is connected, and described No. II clamping plate 6 is connected by rebound and No. I clamping plate 5, described fixed plate 4, I clamping Stepped in divergent contour of 5, No. II clamping plate 6 of plate, is provided with expansion link 7 at described cylinder 1 outer wall, expansion link 7 flexible End is connected with fixed plate 4, and described No. I clamping plate 5 end, No. II clamping plate 6 end are provided with anti-back assembly 8.

It is spacing that described connecting plate, rebound can carry out end face to aluminium section during gripping.

In 5, No. II clamping plate 6 of No. I clamping plate, gripping face in opposite directions is plane or arc surface.

When the gripping face of 5, No. II clamping plate 6 of No. I clamping plate is plane, the quantity of 5, No. II clamping plate 6 of No. I clamping plate It is two or four and be arranged in parallel in pairs.Cylinder 1 drives telescopic arm 2 to move towards, thus by No. I paired clamping plate 5 or No. II clamping plate 6 grip two opposing outer face of aluminium section.

When the gripping face of 5, No. II clamping plate 6 of No. I clamping plate is arc surface, the number of 5, No. II clamping plate 6 of No. I clamping plate Amount is three, and 5, No. II clamping plate 6 of No. I clamping plate all becomes drum type brake to be distributed.Cylinder 1 drives telescopic arm 2 to move towards, thus logical Cross paired No. I clamping plate 5 or No. II clamping plate 6 grips the poroid outer wall of aluminium section.

Distance between adjacent two pieces of No. I clamping plates 5 is less than the distance between adjacent two pieces of No. II clamping plates 6.

No. I clamping plate 5 grips small size aluminium section for clamping type, and No. II clamping plate 6 grips big chi for clamping type Very little aluminium section.

Reticulate pattern is formed on the gripping face of described 5, No. II clamping plate 6 of No. I clamping plate.

The fin of increasing friction force is formed on the gripping face of described 5, No. II clamping plate 6 of No. I clamping plate.

Reticulate pattern or fin can increase the frictional force of gripping contact surface, make gripping operation the most stable.

Forming at least two through hole in described fixed plate 4, screw is screwed into the screwed hole of telescopic arm 2 through above-mentioned through hole In.

Connected mode between No. I 4, No. II clamping plate 6 of clamping plate 5 and fixed plate and No. I clamping plate 5 is for welding, riveting Or screw connects.

The telescopic end of described expansion link 7 is bonding with the connected mode of fixed plate 4.

The back of fixed plate 4 can be supported by expansion link 7, due to fixed plate 5, No. II clamping plate 6 of 4, No. I clamping plate Longer, when using No. II clamping plate 6 to grip aluminium section outer wall, expansion link 7 can effectively improve gripping efficiency, Avoid the phenomenon that gripping is unstable.

Described anti-back assembly 8 include the limiting plate 10 that fixes with No. I clamping plate 5 end, No. II clamping plate 6 end and The clamp 9 being connected by spring and No. I clamping plate 5 end, No. II clamping plate 6 end.

Limiting plate 10 is it can be avoided that the aluminium section of gripping exits.

Described No. I clamping plate 5 end, No. II clamping plate 6 end form the groove adapted with clamp 9 shape.

The clamp 9 of movement is suitable to the gripping that limit mouth entered the aluminium section of working process, and gripping is flexible, it is simple to follow-up Working process.
