Abstract
The utility model relates to a simple type negative pressure pneumatic suction cup device, which is comprised of an air pipe connector, am upper air cylinder, a ball head screw cap, air cylinder connectors, connecting rods, air cylinder connector plates, a lower air cylinder and an air suction cup. The piston output ends of the upper and lower air cylinders are oppositely arranged, the two air cylinder piston heads are connected together through the air cylinder connector, an air cylinder connector plate is connected at the end of each of the two air cylinders, the plate is fixed on the cylinder through screws, two connecting rods are arranged between the two air cylinder connector plates, thread is lathed at the head of the connecting rod, and the connecting rod is fixed on the air cylinder connector plate through screws. Air pipes are connected with the air input and output of the upper air cylinder, and are connected through a solenoid valve. The upper air inlet of the lower air cylinder is connected with no air pipe, but with the atmosphere, and an adjustable air pipe connector is connected with the lower air inlet. The air output pipe of the air pipe connector is connected with the input pipe of the pneumatic suction cup arranged on the lower air cylinder. The utility model has the advantages that the structure is simple, the cost is inexpensive, the work is reliable and the operation is convenient.
Description
Technical field
The utility model relates to a kind of simple negative air suction cup apparatus, use specifically that the relative cylinders of two output pistons form can the production negative pressure air suction cup apparatus.
Background technique
In the modern life, the gas sucker has very wide application.Such as high building cleaning robot, glass handling, ceramic tile carrying etc.But its formation negative pressure of the gas sucker of institute's extensive use mainly contains three kinds of modes at present: the one, use the vacuum pump exhaust.Utilize solenoid electric valve that the gas sucker is linked to each other with vacuum pump, when vacuum pump was bled, the air in the sucker chamber was drawn out of, and formed negative pressure and held object.This sucker reliable operation, suction is big, but needs to be equipped with vacuum pump and control system thereof, and expense is higher; The 2nd, the air-negative-pressure formula.The control valve of this mode will feed from a nozzle from the pressurized air of air pump, forms high-speed jet, the air in the sucker is taken away and is formed negative pressure, makes sucker hold object; This sucker is more convenient, and is with low cost, but its shortcoming is will maintain high-speed jet could form negative pressure always, thereby comparatively serious to the waste of source of the gas; Three is extruding type.It is the volume of the air chamber of one with the sucker inner chamber that this mode leans against the air-proof condition change, thereby the mode that the interior air pressure of sucker is diminished produces negative pressure.But present this mode adopts mechanical force to be applied to that the first-class mode of lever realizes more.
Summary of the invention
At above-mentioned deficiency, the utility model provides a kind of simple negative air suction cup apparatus.
The utility model is realized by following technology:
This device is made up of gas-tpe fitting, upper cylinder, bulb nut, cylinder joint, connecting rod, cylinder interface board, lower cylinder and gas sucker.The piston output terminal of two cylinders is relative up and down, couple together by the head of cylinder joint two cylinder pistons, the end of two cylinders all is connected with a cylinder interface board, this plate by fixed by nut on cylinder, two connecting rods are arranged between two cylinder interface boards, the head car of connecting rod has screw thread, with nut connecting rod is fixed on the cylinder interface board, and making up and down, two cylinders firmly connect.The gas input of upper cylinder, output all are connected to tracheae, link to each other with solenoid valve.The upper gas of the lower cylinder not trachea that enters the mouth communicates with atmosphere, and the lower gas inlet is connected to an adjustable gas-tpe fitting.The gas output tube of this gas-tpe fitting is connected with the gas inlet tube of Pneumatic suction cup on being installed in lower cylinder.
When using, when the control lower piston indentation of upper cylinder at solenoid valve, the piston of lower cylinder will stretch out, thereby produce negative pressure in the sucker that lower cylinder connects.When the piston of upper cylinder stretched out, the retraction piston of lower cylinder disappeared the negative pressure in the Pneumatic suction cup.
Accompanying drawing is a structural principle schematic representation of the present utility model.
Wherein, 1, gas-tpe fitting, 2, upper cylinder, 3, nut, 4, the cylinder joint, 5, connecting rod, 6, the cylinder interface board, 7, lower cylinder, 8, connect tracheae, 9, aspiration dish.
Embodiment
Embodiment: structure as shown in drawings, negative pressure Pneumatic suction cup device by gas-tpe fitting 1, upper cylinder 2, bulb nut 3, cylinder joint 4, connecting rod 5, cylinder interface board 6, lower cylinder 7, connect tracheae 8 and aspiration dish 9 is formed.The piston output terminal of upper cylinder 2 and lower cylinder 7 is relative, couple together by the head of cylinder joint 4 two cylinder pistons, the end of two cylinders all is connected with a cylinder interface board 6, this plate 6 by fixed by nut on upper cylinder 2 and lower cylinder 7, two connecting rods 5 are arranged between two cylinder interface boards 6, the head car of connecting rod 5 has screw thread, with nut 3 connecting rod 5 is fixed on the cylinder interface board 6, and making up and down, two cylinders firmly connect.The gas input of upper cylinder 2, output all are connected to tracheae 1, link to each other with solenoid valve.The upper gas of the lower cylinder 7 not trachea that enters the mouth communicates with atmosphere, and the lower gas inlet is connected to a gas-tpe fitting 1.The gas output tube of this gas-tpe fitting 1 connects by being connected tracheae 8 with the gas inlet tube of aspiration dish 9 on being installed in lower cylinder 7.When the control lower piston indentation of upper cylinder 2 at solenoid valve, the piston of lower cylinder 7 will stretch out, thereby produce negative pressure in the aspiration dish 9 that lower cylinder 7 connects.When the piston of upper cylinder 2 stretched out, the retraction piston of lower cylinder 7 disappeared the negative pressure in the aspiration dish 9.
