Abstract
The invention provides a corrugated power cylinder, relating to a fluid transmission pressure working cylinder. The fluid transmission can be hydraulic transmission or pneumatic transmission. Two ends of the fluid transmission pressure working cylinder are provided with a connecting seat (1) and a connecting seat (2). A corrugated cylinder barrel (3) is arranged between the connecting seat (1) and the connecting seat (2). The fluid transmission pressure working cylinder has no sliding sealing members, which is favorable for improving the product service life.
Description
Affiliated technical field
The present invention relates to a kind of fluid transmission pressure working cylinder, the fluid transmission can be hydraulic transmission or Pneumatic Transmission.
Background technique
Known fluid transmission pressure working cylinder is made of plunger and cylinder barrel, between plunger and the cylinder barrel sliding seal is arranged, and seal request height, sliding seal are easily damaged partss, influence life of product.
Summary of the invention
The objective of the invention is to propose a kind of sliding seal that do not have, the fluid transmission pressure working cylinder that uses bellows to make.
The technical solution used in the present invention is, connecting base (1) and connecting base (2) are arranged at the two ends of fluid transmission pressure working cylinder, between connecting base of the present invention (1) and the connecting base (2) ripple cylinder barrel (3) is installed.
The invention has the beneficial effects as follows there is not sliding seal, help improving life of product.
Description of drawings
Fig. 1 of accompanying drawing is that basic structure axle of the present invention is surveyed schematic representation.
Fig. 2 is an A place partial enlarged drawing among Fig. 3.
Fig. 3 is the basic structure of the present invention sectional drawing cut open of center vertically.
Fig. 4 is the double-action ram structure sectional drawing cut open of center vertically.
Embodiment
Fluid transmission pressure working cylinder shown in Figure 3, two ends have connecting base (1) and connecting base (2), between connecting base of the present invention (1) and the connecting base (2) ripple cylinder barrel (3) are installed.Shown in Figure 1 is the profile of Fig. 3.
Above-mentioned fluid transmission pressure working cylinder, ripple cylinder barrel (3) is known bellows, can be fabricated metals, also can be the fabricplastic rubber product.Connecting base (1) porose (4), connecting base (2) is gone up porose (5), is connected with fluid circuit by known mode, and fluid circuit can be hydraulic drive circuit or Pneumatic Transmission loop.Connecting base (1) and connecting base (2) can be provided with pan (7) and (8) by known mode, also can be the directly fixing forms in known strap bolt hole.The files mounting type of connecting base (1) and connecting base (2) and ripple cylinder barrel (3) can be as shown in Figure 2 be provided with flange (6) by known mode in the edge of ripple cylinder barrel (3) and welds or be bonded on the connecting base (2), also can adopt flange screw to be fixed on the connecting base, and between flange (6) and connecting base (2), place sealing gasket.
Above-mentioned fluid transmission pressure working cylinder, can be as shown in Figure 4, connecting base (1) is the form of connecting base (21), connecting base (2) is the form of connecting base (22), the end face (30) of connecting base (21) is connected with ripple cylinder barrel (3), the back side of end face (30) is connected with ripple cylinder barrel (28) ripple cylinder barrel (29), ripple cylinder barrel (29) is enclosed within the outside of ripple cylinder barrel (28) and arranges along axis coaxle, the end face (31) of connecting base (22) is connected with ripple cylinder barrel (3), the outward edge of connecting base (22) is fixed with housing (33), one end of housing (33) is fixed with supporting seat board (23), the interior edge face of supporting seat board (23) is connected with ripple cylinder barrel (28) ripple cylinder barrel (29), supporting seat board (23) has center hole, and the hinge vent stem part of connecting base (21) is drawn by center hole.
Fluid transmission pressure working cylinder shown in Figure 4, connecting base (22) porose (24) and hole (25), supporting seat board (23) is gone up porose (26) and hole (27), is connected with fluid circuit by known mode, and fluid circuit can be hydraulic drive circuit or Pneumatic Transmission loop.The mounting type of ripple cylinder barrel (28) ripple cylinder barrel (29) can be pressed the mounting type of ripple cylinder barrel (3) as shown in Figure 2 and install.
Fluid transmission pressure working cylinder shown in Figure 1, fluid increase or reduce the axial dimension that changes ripple cylinder barrel (3) in ripple cylinder barrel (3), reach the purpose of transferring power, and the operative orientation classification according to increasing fluid can claim single-acting cylinder.
Fluid transmission pressure working cylinder shown in Figure 4, fluid increases the axial dimension that changes ripple cylinder barrel (3) in ripple cylinder barrel (3), reach purpose to a direction transferring power, fluid increases in the space that ripple cylinder barrel (28) and ripple cylinder barrel (29) surround and changes axial dimension, reach purpose, can claim double acting cylinder to another direction transferring power.
