According to the single-rod double-acting air cylinder disclosed by the utility model, the rod cavity and the rodless cavity are connected by using the second air pipe which can be connected or disconnected, the piston descends under the action of gravity, air in the rod cavity below the piston enters the rodless cavity above the piston through the second air pipe, so that the air is saved; and because an air compressor intermittently works, the effective power of the air compressor is improved and the energy consumption is reduced.
Description
Technical field
The utility model relates to a kind of cylinder, is specifically related to a kind of single pole double-acting cylinder.
Background technique
Pneumatic apparatus is a kind of energy conversion device, and it is that compressed-air actuated pressure energy is converted into mechanical energy, and driving mechanism is realized straight reciprocating motion, swung, rotatablely moves or percussion action.Pneumatic apparatus is divided into the gentle motor two large classes of cylinder, and cylinder is used for providing straight reciprocating motion or swing, ouput force and space rate or angle of oscillation displacement, and the gas motor is used for providing the continuous rotary motion, the output torque and rotational speed.
The pneumatic apparatus of normal use is the single pole double-acting cylinder, formed by cylinder barrel, piston, piston rod, front cover, rear end cover and Sealing etc., double-acting cylinder inside is divided into two chambeies by piston, has rod end chamber to become rod chamber, and piston-less lumen is called rodless cavity.
Utilize above-mentioned single pole double-acting cylinder to drive external agency and realize that percussion action has been mature technology, as shown in Figure 1, the single pole double-acting cylinder vertically arranges, its rod chamber and rodless cavity all are connected with air compressor by tracheae, tracheae is provided with switch valve, with the break-make between control rod chamber or rodless cavity and the air compressor.The working principle of this single pole double-acting cylinder is: when being positioned at the rodless cavity input compressed-air of top, and the rod chamber exhaust, the pressure difference in cylinder two chambeies acts on that formed making every effort to overcome takes resistant load pushing piston motion on the piston, and piston rod is stretched out downwards; When the rod chamber input compressed-air, the rodless cavity exhaust is retracted piston rod; Rod chamber and rodless cavity replace air inlet and exhaust, and piston is realized the reciprocating impact motion.Acceleration of motion and impulse force that this structure does not need piston rod to have in a period of time before impacting beginning, but the pressurized air input is arranged always but in the rodless cavity of cylinder during this period of time, and the gas in the rod chamber is directly discharged, cause compressed-air actuated waste, and the idle work of air compressor, energy consumption is large.
For solving the problems of the technologies described above, need provide the single pole double-acting cylinder of a kind of pressurized air utilization ratio height, the useful horsepower that improves air compressor, minimizing energy consumption.
Summary of the invention
The utility model purpose provides a kind of single pole double-acting cylinder, by the improvement of structure, and pressurized air utilization ratio height, the useful horsepower that improves air compressor, minimizing energy consumption.
For achieving the above object, the technical solution adopted in the utility model is: a kind of single pole double-acting cylinder, comprise piston and piston rod, described cylinder interior is divided into rod chamber and rodless cavity by piston, rodless cavity is located at the top of rod chamber, be connected with the second tracheae between described rod chamber and the rodless cavity, this second tracheae is provided with the second switch valve.
Preferably, described second switch valve is the 2/2-way solenoid valve, but is not limited to the 2/2-way solenoid valve, can also select other switch valves that can control the second tracheae break-make according to actual conditions.
In the technique scheme, described rod chamber is connected the first tracheae and is connected with air compressor with rodless cavity, and this first tracheae is provided with the first switch valve.
Further technological scheme, described the first switch valve is 3-position-3-way solenoid valve, in order to control the break-make between rod chamber or rodless cavity and the air compressor.
The utility model working principle: when cylinder piston begins when descending, the first switch valve meta is closed, the left position of second switch valve is connected, and piston and piston rod are descending under Action of Gravity Field, and the air in the rod chamber of piston below enters in the rodless cavity of piston top by the second tracheae.When piston walked to desired location and need to increase pressure, the right position of second switch valve disconnected the upper connection of the first switch valve, pressurized air flows into the rodless cavity of piston top through the first tracheae, the rodless cavity internal pressure increases, and moment is accelerated the realization percussion action under pressure for piston and piston rod;
When cylinder piston was up, the right position of second switch valve disconnected, the next connection of the first switch valve, and the rod chamber of pressurized air below the first tracheae flows into piston, the rod chamber internal pressure increases, and piston is up under pressure, and piston rod is retracted.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1. but owing to utilize the second tracheae of break-make to connect between rod chamber of the present utility model and the rodless cavity, piston can be descending under Action of Gravity Field, air in the rod chamber of piston below enters in the rodless cavity of piston top by the second tracheae, save air, the air compressor intermittent work, the useful horsepower of raising air compressor, the energy consumption that reduces.
