A kind of instrument for dismantling oil cylinder head, including the circular nylon axle of for can connecting together successively from inside to outside
Watt, a circular casing and a circular anchor ear；Described circular nylined bearing is put together by two semicircle nylined bearings, and
Lubricating grease is provided with the inwall of circular nylined bearing；Described circular casing is put together by two semicircle sleeve pipes, and
Several double wedges are circumferentially with the naked end face being exposed on the external of circular casing；Described circular anchor ear is by two semicircle anchor ears
It is put together.
Here circular nylined bearing is used to be arranged on the piston rod, and circular casing is set in circular nylined bearing outer wall
On, circular anchor ear is set in circular casing outer wall circular casing and circular nylined bearing further are fixed on into piston rod
On；Circular casing and circular anchor ear typically use metal material, can not have cut because piston rod surface requirement is smooth, so making
Piston rod and circular casing are isolated with circular nylined bearing, and is prevented on the piston rod using the circular nylined bearing of lubricating grease handle is viscous
Only it falls down, while also functioning to the effect of lubrication；It is circumferentially with the naked end face being exposed on the external of circular casing some
Individual double wedge, double wedge here is used to be meshed with the groove on oil cylinder head；The specific occupation mode of the utility model is：Will be viscous
The circular nylined bearing for having lubricating grease is arranged on the piston rod, and circular casing is set in circular nylined bearing outer wall, circular casing
On double wedge be meshed with the groove on oil cylinder head, it is then with circular anchor ear that circular casing and circular nylined bearing is preferably solid
It is fixed then to block the instrument using socket spanner of the prior art to unscrew oily disputer on the piston rod, then take out
Piston rod, and cylinder barrel is stayed in frame, carry out changing the work such as oil sealing.
It is preferred that the outer wall of the circular casing is divided into the first ladder and second-order for successively decreasing successively in the axial direction
Ladder.
Wherein the first ladder is the position that circular anchor ear is arranged, and the second ladder relatively reduces diameter and is used to facilitate socket to pull
The mode of hand, the setting of the first ladder and the second ladder so that whole instrument application is more preferably, easy to use.
It is preferred that the outer wall of the circular casing is divided into the first ladder, the second ladder for successively decreasing successively in the axial direction
With the 3rd ladder.
Wherein the first ladder is used to prop up and is arranged in the second ladder circular anchor ear to prevent its displacement, and the second ladder is circle
The position that shape anchor ear is arranged, the 3rd ladder relatively reduces the mode that diameter is used to facilitate socket spanner, the first ladder, second-order
Ladder, the setting of the 3rd ladder so that whole instrument application is more preferably, easy to use.
It is preferred that the two ends of described semicircle anchor ear outwards extend is formed with a fixation ear.
It is preferred that each is fixed on ear is correspondingly provided with bolt hole, the fixed ear in two semicircle anchor ears is worn by bolt
Cross bolt hole and the circular anchor ear of fixed formation one.
For the oil cylinder head being arranged in vehicle frame, this fixed form seems simpler convenience.
The beneficial effect that the utility model employs above-mentioned technical proposal is：
The utility model is that a kind of need not dismantle many annexes and just can effectively and quickly be repaired oil cylinder oil leak feelings
The instrument for dismantling oil cylinder head of condition.Specifically used mode of the present utility model is：The circular nylon of lubricating grease will be stained with
Bearing shell is set on piston rod, and circular casing is set in circular nylined bearing outer wall, double wedge and oil cylinder head on circular casing
On groove be meshed, then with circular anchor ear by circular casing and circular nylined bearing preferably it is fixed on the piston rod, then
The instrument is blocked using socket spanner of the prior art to unscrew oily disputer, then take out piston rod, and cylinder barrel is stayed
In frame, carry out changing the work such as oil sealing；Avoiding the need for many annexes of dismounting by this instrument can just be carried out effectively
Maintenance, greatly shortens the maintenance time of failure, and efficiency high, the also work to maintenance personal offers convenience, and reduces cost of labor.
