Description
Technical field
Mechanical device technical field is the utility model is related to, specifically a kind of buffer.
Background technology
In the industries such as automation, robot, material transferring, packaging, steel, lathe, harbour, railway, the equipment course of work
In, in order to prevent hard collision from causing mechanism damage, it is necessary to be equipped with safety buffer device.Buffer is by hydraulic damping to effect
Buffer deceleration is carried out to stopping in object thereon, can play a certain degree of protective effect.
When buffer is collided pressure, kinetic energy is given to piston through impact head and spring, makes its motion.Buffer works
Intracavitary is equipped with push rod and fluid.Fluid in the motion extruding working chamber of piston, compresses its back-moving spring, while make fluid
Squeezed out from working chamber throttle orifice, into oil storage chamber.The buffer of every profession and trade application at present, due to design structure,
Working chamber and balancing gate pit's volume are inconsistent, fluid when two intracavitary flow, it is necessary to pressure accumulater compensates to volume, structure
It is more complicated.
The content of the invention
For overcome the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of buffer, is stored with cancelling
Pressure device, accomplish lightweight.
For achieving the above object, the head of damping fluid, impact head and impact bar is marked with cylinder of the present utility model
Portion connects, and the afterbody of impact bar is set with piston ring, and driven plug sleeve is mounted in the inside of impact bar, is provided between cylinder and impact bar
Back-moving spring；Impact head is impacted, and back-moving spring is compressed, impact bar afterbody and piston ring collective effect, extrudes cylinder work
Make the damping fluid of intracavitary, damping fluid flow to oil storage chamber by the oil duct of impact bar, and damping fluid promotes driven plug to reset.
The cylinder is with fixed external screw thread is easily installed, and the head endoporus of cylinder is installed with fixed cover, fixed cover
Endoporus is provided with guide ring one and sealing ring one, and the oil fill plug of cylinder afterbody is connected with cylinder screw, the damping fluid in cylinder
Communicated by the oil duct in impact bar with the oil storage chamber in impact bar；The impact head of impact club head is threadedly coupled with impact bar,
Driven in impact bar is provided with guide ring two and sealing ring two beyond the Great Wall, and the head endoporus of impact bar, which is provided with, to be used to fill in row to driven
The hole back-up ring of position limitation protection, the piston ring set of impact bar afterbody is in cylinder.
One end of the fixed cover is that can carry external screw thread with the optical axis of the counterbore interference fits of cylinder, the other end.
The internal diameter of the guide ring one is more than the external diameter of piston ring.
The impact bar carries air-vent.
Compared with prior art, working chamber is located at inner barrel to the utility model, and oil storage chamber is located inside impact bar, buffering
When device works, impact bar afterbody and piston ring collective effect, damping fluid is extruded, damping fluid passes through in impact bar
Portion's oil duct flow to oil storage chamber, because working chamber is consistent with the internal diameter of oil storage chamber, changes in the absence of volume, without energy storage device, structure
Simply, buffering effect is safe and reliable, has accomplished lightweight.
Brief description of the drawings
Fig. 1 is structure diagram of the present utility model.
Fig. 2 is enlarged drawing at Fig. 1 I.
Embodiment
As shown in Figure 1 and Figure 2, damping fluid 14 is marked with cylinder 1 of the present utility model, damping fluid 14 passes through impact bar
Oil duct 15 in 12 communicates with the oil storage chamber 16 in impact bar 12；One end of fixed cover 3 is optical axis, can be with the counterbore mistake of cylinder 1
Cross cooperation, with ensure cylinder 1 and fixed cover 3 assemble after axiality, the other end of fixed cover 3 carries external screw thread, for cylinder
Together, the endoporus of fixed cover 3 is provided with guide ring 1 and sealing ring 1 to the head endoporus spinning of body 1；Cylinder 1 carries outer spiral shell
Line, it is easy to the installation of cylinder 1 to fix；The oil fill plug 2 of the afterbody of cylinder 1 is threadedly coupled with cylinder 1.The impact head on the head of impact bar 12
8 are threadedly coupled with impact bar 12；The afterbody of impact bar 12 is set with piston ring 13, and piston ring 13 is sleeved in cylinder 1；Driven plug
9 are sleeved on the inside of impact bar 12, and driven plug 9 is provided with guide ring 2 11 and sealing ring 2 10；The head endoporus of impact bar 12
Provided with hole back-up ring 7, for carrying out position limitation protection to driven plug 9；Impact bar 12 carries air-vent 17；Cylinder 1 and impact bar 12
Between be provided with back-moving spring 6.The internal diameter of the guide ring 1 is more than the external diameter of piston ring 13, and the step being here formed as can be to prevent
Only impact bar 12 is deviate from from cylinder 1, plays position-limiting action.
The course of work of the present utility model is as follows：
When impact head 8 is impacted, back-moving spring 6 is compressed, afterbody and the collective effect of piston ring 13 of impact bar 12, right
The damping fluid 14 of the working chamber of cylinder 1 is extruded, and damping fluid 14 flow to oil storage chamber 16 by the oil duct 15 of impact bar 12, with
The damping fluid 14 for oil storage chamber 16 gradually increases, and damping fluid 14 promotes the driven movement of plug 9, the synchronous appearance for increasing oil storage chamber 16
Product.
The process that the working chamber of cylinder 1 is compressed, it is that the afterbody of impact bar 12 and the squeezed air-damping fluid 14 of piston ring 13 do work
Process, this process consumes a large amount of kinetic energy, can play cushioning effect.When work finishes, the spring 6 that is reset of impact bar 12 pushes away
To home position, damping fluid 14 is back in the working chamber of cylinder 1, and driven plug 9 resets, and completes a working cycles.
