The beneficial effects of adopting above-mentioned technical scheme are: the technical scheme can replace the clamping mode of the traditional vice in the past. Because the corner pushing cylinder can be synchronously linked, and the acting force of the cylinder is more controllable compared with that of the vice, the master operation does not need to manually lock screws any more, the clamping efficiency can be improved, the collision damage of the profile is reduced, and the reject ratio of the product is reduced. The method can keep the clamped section stable for a long time and prevent deformation. The rotation of the rotating arm can facilitate the putting-in and taking-out of the grabbing and clamping station of the section bar.

When the fixture works, the air cylinders on two sides of the product push the levers to quickly compress and flatten the product, so that the working time of installation and clamping is shortened, and the contact surface between the product and the fixture is reduced.

And the buffer effect of the buffer block is added, so that the friction force after clamping is improved, and the possibility of the section bar being crushed is reduced. The positioning column is used for limiting two ends of the section bar with the largest deformation amount, and mainly preventing the section bar from being deformed left and right and being deformed in a torsion mode. Compared with the traditional locating pin, the locating column is larger in size, and the covered section bar is larger in local area.

As a further improvement of the utility model, the corner pressing cylinders at two sides of the profile are arranged in mirror symmetry; along the length direction of the section bar, the corner pressing cylinders are arranged at equal intervals.

The beneficial effects of adopting above-mentioned technical scheme are: the buffer block is replaceable, and the bolt is buried in the through hole, so that the hard bolt is prevented from damaging the profile.

As a further development of the utility model, the damping element is provided with a projection projecting from the end of the swivel arm.

The beneficial effects of adopting above-mentioned technical scheme are: the back of the buffer block of the front extension section is not supported by the rotating arm, so that the buffer block has better elastic buffer effect.

As a further improvement of the utility model, the buffer block is made of rubber.

As a further improvement of the utility model, the cross sections of the two positioning columns of the profile respectively positioned are intersected with corner pressing cylinders.

The beneficial effects of adopting above-mentioned technical scheme are: the special corner pressing cylinder is arranged at two ends of the profile to press down and limit.
