Description
Technical field
The utility model relates to a kind of cylinder, especially reciprocating air cylinder and using the grease pump of the reciprocating air cylinder.
Background technique
Piston linear reciprocating motion type cylinder is that compressed air energy is switched to mechanical energy using compressed air as the energy,
With reciprocating executive component in pneumatic system, the effect of cylinder is that load is overcome to drive element movement.
Cylinder in the prior art mainly has single-acting cylinder and two kinds of double-acting cylinder, and this cylinder controls its piston
The air valve of movement is mutually indepedent.In the side air inlet of cylinder, piston pushes away single-acting cylinder by the spring of the cylinder other side is arranged in
Power resets, to can not achieve automatically moving back and forth for piston under cylinder charge shape body；Double-acting cylinder needs ceaselessly to convert
The intake and exhaust direction of cylinder, is just able to achieve the reciprocating motion of piston, and operating process is complicated.
Therefore, when doing linear reciprocating motion using the cylinder driving element of both forms, usually require with it is special
Automatic control system connection is just able to achieve, and causing cylinder system, structure is complicated, and manufacturing cost is high.
Current automatic reciprocating air cylinder, reversal valve and intake and exhaust pipeline are set to outside cylinder, make cylinder complex contour,
Occupied space is big, installs not convenient, higher cost.In space, especially small occasion cannot be used, and intake and exhaust pipeline connects
Point is more, i.e. leakage point is more, repairs more complicated.
Such as the automatic linear double-acting cylinder that Chinese patent CN103256273A is announced, pass through the valve being arranged on piston
Core, spool positioning device and spool reversing arrangement control the connected relation between the first air cavity, the second air cavity and third air cavity,
It realizes in the case where continuously to cylinder charge state and without other control equipment, the automatic reciprocating linear motion of piston,
But but its valve is placed on piston head so that inner chamber of cylinder block is to be impacted in movement, robust motion is poor, internal structure mistake
In complexity, processing cost is excessively high, and service performance is unstable.
Existing grease pump mostly uses greatly the mode for squeezing out oil, and the oil of liquid condition flows into grease pump outer tube sleeve bottom naturally
What coin was then arranged after the oil inlet in portion, in outer tube sleeve bottom mention, and oil is extracted into the external world by one formula of power squeezed again by flitch, such as in
The top of the Pneumatic grease pump that state patent CN201884914U is announced, including gas distribution, gas chamber cap assemblies, gas distribution connects tracheae
One end, the other end of tracheae connects gas chamber cap assemblies；Gas chamber cap assemblies include air chamber cover, are successively set from inside to outside in air chamber cover
It is equipped with distribution paper washer, distributing valve seat, limit plate, distribution sliding block is set in limit plate；Damping spring piece is arranged in the side of limit plate,
Damping spring piece and limit plate, distributing valve seat, distribution fixation with paper pad are set in air chamber cover by hex screw；Damping spring
Piece is sheathed on distribution sliding block；Air chamber cover is fixedly connected on to the top of gas distribution by soket head cap screw, makes gas chamber cap assemblies
It is fixedly connected with gas distribution, which is exactly the oil inlet mode that oil inlet is flowed into using nature, and the oil inlet mode is by oil
Mobility influences, if oil can not flow into oil inlet naturally when the poor fluidity of low-temperature condition oil, material is mentioned on grease pump
Oil can not be just transported to top by plate, and such grease pump cannot be used in the lower environment of temperature, meanwhile, distribution sliding block needs not
Disconnected sliding, being prone to wear causes grease pump to be out of order, cisco unity malfunction, needs more frequently to replace distribution sliding block and be tieed up
It repairs.
