Section type multifunctional expanding fixture

Abstract

The invention discloses a section type multifunctional expanding fixture. The fixture comprises multiple sections of expanding mechanisms, a telescopic air cylinder and an installing base. The expanding mechanisms comprise fixed expanding mechanisms and sliding expanding mechanisms; the sliding expanding mechanisms comprise sliding expanding fixtures and pushing air cylinders; the shapes of the contacting faces of the fixed expanding mechanisms are different from the shapes of the contacting faces of the sliding expanding mechanisms. The fixture has the advantages that the structure is compact, the size is small, an item can be picked by embedding the fixture into an item, the picking of more kinds of items with different shapes can be achieved, and the time of replacing the fixture is reduced.

Description

technical field [0001] The invention relates to the field of clamps, in particular to a segmented multifunctional external tension clamp. Background technique [0002] The clamps currently used are usually of the outsourcing type, that is, the inside of the clamp is attached to the outer surface of the object and pressure is applied to the inside, so as to achieve the purpose of clamping the item. The clamp used to clamp the item in this way has a large volume and is not compact enough. Moreover, the clamp wrapped on the outer surface of the object will affect the observation of the object during the clamping process, and it is difficult to find the damage or tilt of the object in time, which may easily cause safety hazards; on the other hand, the general fixture is designed based on the shape of the object, which is usually only suitable for For certain types of items with similar shapes, it is easy to slip when clamping items with a large difference in shape from the fixtu...

[0002] The clamps currently used are usually of the outsourcing type, that is, the inside of the clamp is attached to the outer surface of the item and pressure is applied to the inside, so as to achieve the purpose of clamping the item. The clamp used to clamp the item in this way has a large volume and is not compact enough. Moreover, the clamp wrapped on the outer surface of the object will affect the observation of the object during the clamping process, and it is difficult to find the damage or tilt of the object in time, which may easily cause safety hazards; on the other hand, the general fixture is designed based on the shape of the object, which is usually only applicable For certain types of items with similar shapes, it is easy to slip when clamping items with a large difference in shape from the fixture, which will reduce the positioning accuracy of subsequent placement or assembly, and even cause production hazards in severe cases; therefore, when the shape of the item to be clamped When the difference is large and the difference is large, the fixture needs to be replaced
