Abstract

The invention relates to a pneumatic diaphragm type wet blank clamping device and a use method thereof, and belongs to a clamping device of an object with certain intensity, in particular to the clamping of wet blank with certain intensity, such as the clamping of building blocks, bricks newly molded, etc., the invention aims at solving the problem that the traditional rigid clamping device can not clamp and carry the wet blank. The device comprises a rigid support 4, an elastic diaphragm 2, a fixed clamp plate 3, a pneumatic pipeline 7, a reversal valve 5, and a pressure reducing valve 6. When high pressure gas is charged into a pipeline, the elastic diaphragm deforms and uniformly contacts with a clamped object 1, a force uniformly distributed is exerted on the clamped object, when a frictional force f generated by a composite force F is larger than the weight W of the clamped object, and the transportation and piling of the clamped object can be realized through impressing moving force and motion to the rigid support 4 of the clamped object, to achieve the reliable and lossless clamping and carrying of the wet blank.

Description

Pneumatic power diaphragm type wet blank clamping device and using method thereof

One, technical field

Pneumatic power diaphragm type wet blank clamping device of the present invention and using method thereof belong to the holding device to the object with certain intensity, relate in particular to the clamping to the wet base with certain intensity, as the clamping of wet bases such as the building block of firm moulding, brick.

Two, background technology

In the engineering practice, usually need some objects are carried, this just needs holding device object is clamped, and by jack up unit object is lifted then, moves to the place that needs again and puts down.Existing holding device relies on a pair of or one group of gripper jaw, by machinery or hydraulic pressure or pneumatic mode, allows two gripper jaw moving linearlies or gyroscopic movement, and realization is to the clamping of material, thereby finishes operations such as transportation to material, piling.This holding device does not have any problem to the clamping of object (as metal objects) with cooresponding intensity, but the object relatively low (as frangible glass, pottery etc.) to intensity, very easily cause the damaged even broken of object in the clamping, the object lower to intensity (as wet bases such as the building block of firm moulding, bricks) then can't be finished clamping.

Realize direct carrying to jobbie, need clamp this object with certain means, realize carrying by corresponding running gear again, general clamping to object, by applying certain power in the horizontal direction, overcome the gravity of object by the friction force that produces, realize clamping, thereby realize operations such as lifting, carrying object to object.In the prior art, clamping to object mainly relies on the clamping of the gripper jaw realization of rigidity to object, when object is not when being in the jaw centre, it is mobile in the process of object being carried out clamping object to be produced in the horizontal direction, when if the insufficient strength of object is big, it is damaged that object is produced, and makes the seamed edge of object produce defective especially.

Want the wet such object of base of object building block directly to carry,, must cause the distortion even the breakage of building block if adopt the gripper jaw of rigidity that it is carried out clamping.Causing damaged major cause is to its clamping the time, in order to reach enough friction force, must apply enough positive pressures, because the active area of positive pressure is little, just have bigger stress, this will make and resemble the seamed edge breakage that is similar to the such object of the wet base of building block, even its integraty is destroyed.

In the prior art, transportation after the moulding such as building block, maintenance etc., it all is the band pallet operation, actual carrying to object etc. is all carried out pallet, so just need to consume a large amount of pallets, simultaneously owing to only place one deck building block on each pallet, need configuration Lift-slab machine, the equipment such as plate machine, primary and secondary car, piler that fall finish maintenance to building block, transportation, to operations such as many, and to occupy more space and come maintenance and deposit these building blocks and pallet.Exist in the practical application production efficiency low, expend that tray number is big, big, the high deficiency of manufacturing cost take up room.Its major cause is the stacking that can't realize wet base, can't allow wet base maintenance under the stacked state, if can realize the stacking of wet base, just can on the pallet device of pallet (or be similar to), pile up multi-layer building block, thereby reduce dependence to pallet, reduce the maintenance space, no longer need Lift-slab machine and fall the plate machine, the transportation of building block also can be by the primary and secondary car of simple conveyer system replace complex costliness.

Three, summary of the invention

The purpose of Pneumatic power diaphragm type wet blank clamping device of the present invention and using method thereof is, overcome above-mentioned weak point of the prior art, provide a kind of can be directly to finish harmless or the holding device of little damage and the technical scheme of using method of transportation, piling such as direct clampings of wet base such as building blocks.
