Description

Valve oil seal dismounting tool

Technical Field

The utility model relates to an engine disassembly equipment technical field, specific theory relates to a dismantlement frock for dismantling valve oil blanket on the cylinder head.

Background

The engine cylinder head is mounted on the engine cylinder block, and seals the cylinder block from the upper part to form a combustion chamber, and a valve guide pipe is mounted on the cylinder head. The valve oil seal is one kind of oil seal, and is formed by vulcanizing outer frame and fluororubber together, and the radial mouth of the oil seal is equipped with self-tightening spring or steel wire, and is used for sealing valve guide pipe on the cylinder cover of engine.

In the process of carrying out engine development experiments, the engine is frequently disassembled and assembled. When the cylinder cover is disassembled and assembled, some parts are recyclable parts, such as the cylinder cover, the cylinder cover not only needs to be recycled, but also is high in price, and the cylinder cover needs to be disassembled and assembled without being damaged; some parts are disposable parts, such as valve oil seals on a cylinder head, and must be replaced after being detached once in use. However, in the disassembly process, the valve oil seal is fixed with the valve guide pipe of the cylinder cover in an interference fit manner, and a large amount of lubricating oil is arranged on the surface of the valve oil seal, so that the disassembly is very difficult, the valve guide pipe of the cylinder cover can be damaged by slight carelessness, the integrity of the cylinder cover is damaged, the cylinder cover with high price cannot be used continuously, and the resource waste is caused.

SUMMERY OF THE UTILITY MODEL

To the above defect that prior art exists, the utility model provides a frock is dismantled to valve oil seal, this frock is dismantled to valve oil seal can reach and not destroy the valve guide and take off the purpose that the valve oil seal was taken off from the valve guide, and not only safe convenient but also improved work efficiency.

In order to solve the technical problem, the technical scheme of the utility model is that:

valve oil seal dismantles frock, including clamping unit, clamping unit is including pressing from both sides tight seat and the clamping piece that is used for pressing from both sides tight valve oil seal, it holds to be provided with on the tight seat of clamp the holding tank of valve oil seal, the clamping piece sets up on the cell wall of holding tank.

The clamping piece is a screw or a screw rod, and a threaded hole matched with the screw or the screw rod is formed in the groove wall.

Wherein the clamping piece is a screw.

The clamping pieces are four, and the four clamping pieces are arranged in an annular array by taking the axis of the accommodating groove as a central axis.

Wherein, the clamping seat is provided with a handle.

After the technical scheme is adopted, the beneficial effects of the utility model are that:

the utility model provides a frock is dismantled to valve oil seal, because including the tight subassembly of clamp that is used for pressing from both sides tight valve oil seal, when using, establish the tight seat cover of clamp on the valve oil seal, the clamping piece through tight subassembly of clamp presss from both sides the valve oil seal tightly, then can easily dismantle the valve oil seal from the valve pipe through rotatory tight subassembly of clamp. At whole dismantlement in-process, clamping components do not have with the contact of valve pipe, can not cause destruction to the valve pipe, consequently, the utility model discloses valve oil seal dismantles frock can reach and does not destroy the valve pipe and take off the purpose of valve oil seal from the valve pipe, makes the dismantlement work safe convenient more, and efficiency is higher.

Drawings

FIG. 1 is a schematic structural view of the valve oil seal dismounting tool of the present invention;

in the figure: 1-cylinder cover, 2-valve guide pipe, 3-valve oil seal, 4-clamping seat, 41-accommodating groove, 5-clamping piece and 6-handle.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in figure 1, the valve oil seal dismounting tool comprises a clamping assembly, the clamping assembly comprises a clamping seat 4 and a clamping piece 5 used for clamping a valve oil seal 3, a containing groove 41 containing the valve oil seal 3 is formed in the clamping seat 4, and the clamping piece 5 is arranged on the groove wall of the containing groove 41. In practical application, the clamping seat 4 may also be a cylindrical structure with two open ends, and the clamping member 5 is disposed on the cylindrical wall of the cylindrical clamping seat, and the structure of the clamping seat 4 is not limited in this embodiment.

As shown in fig. 1, the clamping member 5 is a screw or a screw rod, and a threaded hole matched with the screw or the screw rod is formed in the wall of the groove. Since the valve oil seal 3 is a disposable part and the end of the screw is tapered, the valve oil seal 3 can be better clamped, and therefore, the clamping member 5 is preferably a screw in this embodiment.

As shown in fig. 1, in the present embodiment, four clamping members 5 are preferably provided, and the four clamping members 5 are arranged in an annular array around the axis of the accommodating groove 41. In practical applications, the number of the clamping members 5 is not limited, and a designer can design the clamping members according to actual conditions.

As shown in fig. 1, the gripper seat 4 is provided with a handle 6 in this embodiment. Through setting up handle 6, made things convenient for workman rotary clamping subassembly, made the dismantlement work more laborsaving, reduced working strength.

During operation, the clamping seat 4 is aligned to the valve oil seal 3 on the cylinder cover 1, the clamping seat 4 is sleeved on the valve oil seal 3, then the four clamping pieces 5 are slowly screwed and tightly combined with the surface of the valve oil seal 3, the clamping seat 4 is fixed on the valve oil seal 3, after the clamping seat is fixed, the clamping seat 4 drives the valve oil seal 3 to rotate through the rotating handle 6, and the valve oil seal 3 is screwed down from the valve guide pipe 2 under the action of rotating force, so that the disassembly work of the valve oil seal 3 is completed.

At above whole dismantlement in-process, clamping component does not have and valve pipe 2 contact, can not cause destruction to valve pipe 2, has reached and has not destroyed valve pipe 2 and with the purpose that valve oil seal 3 took off from valve pipe 2, consequently, the utility model provides a valve oil seal dismantles frock is safe more convenient, and efficiency is higher.

The foregoing is illustrative of the best mode of the invention, and details not described herein are within the common general knowledge of a person of ordinary skill in the art. The protection scope of the present invention is subject to the content of the claims, and any equivalent transformation based on the technical teaching of the present invention is also within the protection scope of the present invention.
