Abstract
The utility model provides a self-locking and self-unlocking loop hydraulic oil cylinder. An oil cylinder main piston is arranged at one end in a cylinder body of the hydraulic oil cylinder, a self-locking oil inlet pipe is arranged on the upper part of the other end of the cylinder body, and an unlocking oil inlet pipe is arranged on the lower part of the other end of the cylinder body. An oil way self-locking piston is arranged in the cylinder body between the self-locking oil inlet pipe and the unlocking oil inlet pipe. An oil cylinder check valve is arranged on the self-locking oil inlet pipe. The self-locking oil inlet pipe and the unlocking oil inlet pipe are communicated with the oil way self-locking piston respectively. A cylinder cover is connected with the cylinder body through bolts. According to the oil cylinder, an additional locking mechanism and an additional unlocking mechanism are not required; and the oil cylinder can be locked and unlocked conveniently and quickly at any point without the limitation of travel.
Description
Technical field
The utility model relates to the hydraulic transmission field, specially refers to a kind of self-locking and explains the lock loop hydraulic jack by oneself.
Background technique
The self-locking hydraulic jack designs to the specific demand of machinery, lathe specially, in the using process of mechanical machine tool, owing to have powerful pressure in mechanical machine tool, to operate, so the oil cylinder in the lathe is to pin.Self-locking oil cylinder in the market all has: 1, receive travel limits during self-locking, and can't self-locking when stroke is not enough; 2, the diamond block mechanical self-latching produces infringement to oil cylinder, and causing sometimes can not self-locking or release; 3, defective such as poor stability in the use is installed and the debugging trouble.
Summary of the invention
The purpose of the utility model is to provide a kind of hydraulic drive oil circuit self-locking piston motion to realize that the self-locking of self-locking or release explains the lock loop hydraulic jack by oneself.
For realizing above-mentioned purpose, the technological scheme of the utility model is:
The lock loop hydraulic jack is explained in a kind of self-locking by oneself; Comprise oil circuit self-locking piston, oil cylinder one-way valve, oil cylinder main piston, cylinder cap, cylinder body, self-locking oil inlet pipe and release oil inlet pipe; End in the cylinder body of this hydraulic jack is equipped with the oil cylinder main piston, and the self-locking oil inlet pipe is equipped with on the other end top of cylinder body, and the release oil inlet pipe is equipped with in the bottom; Oil circuit self-locking piston is housed in the cylinder body between self-locking oil inlet pipe and the release oil inlet pipe; The oil cylinder one-way valve is housed on the self-locking oil inlet pipe, and self-locking oil inlet pipe and release oil inlet pipe are connected with oil circuit self-locking piston respectively, and cylinder cap is connected with cylinder body with bolt.
The good effect of the utility model is:
1 need not be extra locking mechanism and release mechanism, locking and release convenient and swift; 2 can bear the power up to tens tons; 3 do not need extra action; 4 can be any locking point, does not receive travel limits; 5 is easy for installation, and the little suitable small space of volume is installed; 6 good seals; Reasonable in design.
Description of drawings
Lock loop hydraulic jack self-locking state schematic representation is explained in Fig. 1, self-locking by oneself;
Lock loop hydraulic jack released state schematic representation is explained in Fig. 2, self-locking by oneself.
Embodiment
Further specify the embodiment of the utility model below in conjunction with accompanying drawing 1-2.
The self-locking process:
Referring to Fig. 1, cylinder cap 4 usefulness bolts 5 are connected on the cylinder body 6, after 7 oil-feeds of self-locking oil inlet pipe; Oil is released oil circuit self-locking piston 1; When oil circuit self-locking piston 1 was pulled to the bottom of cylinder block 6, the oil cylinder oil return circuit was blocked, and this moment, oil cylinder was a locking state; Even cut off the oil circuit of self-locking oil inlet pipe 7, oil cylinder still is lockable.Under this state, hydraulic oil is given oil cylinder main piston 3 fuel feeding from oil cylinder one-way valve 2, make oil cylinder main piston 3 retract work, and oil cylinder stroke is the arbitrfary point.
Releasing process:
After oil gets into from release oil inlet pipe 8, the bottom of oil circuit self-locking piston 1 from cylinder block 6 ejected, oil circuit self-locking piston 1 is got back to initial position, and this moment, the oil cylinder oil return circuit was opened, and oil cylinder main piston 3 resets, and the self-locking state state is untied.
