Problems solved by technology

Since the valve oil seal 4 is a soft material, the part where it is assembled with the valve guide 3 protrudes from the engine cylinder head 2. During the assembly process, the valve oil seal 4 and the valve guide 3 may not be fully matched due to uneven force on the auxiliary equipment. The inner wall of the oil seal 4 in contact with the valve guide 3 is worn or broken, and even causes the valve guide 3 to bend and deform, which ultimately affects the operation of the engine

Embodiment Construction

[0032] In order to make the above objects, features and advantages of the invention more obvious and comprehensible, specific implementations of the invention will be described in detail below.

[0033] In the following description, a lot of specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, and those skilled in the art can do it without departing from the meaning of the present invention. By analogy, the present invention is therefore not limited to the specific examples disclosed below.

[0034] Such as Figure 2 to Figure 6 As shown, the valve oil seal assembly tool 1 of the present invention includes a press-fit rod 11, a positioning rod 12, a sliding sleeve 13 and a handle 14; The first end 111 is provided with a positioning rod mounting hole 113, and the second end 112 of the press-fit rod 11 is fixedly connected with the handle 14. The ab...

Abstract

The invention discloses a valve oil seal assembly tool which comprises a press assembly rod, a positioning rod, a sliding sleeve and a handle. The press assembly rod is slidably connected with the sliding sleeve in a matched manner, a positioning rod mounting hole is formed in a first end of the press assembly rod, a second end of the press assembly rod is fixedly connected with the handle, and the positioning rod is provided with a fixed end matched with the positioning rod mounting hole and a positioning end matched with a valve guide pipe. The contacting area of the valve oil seal assembly tool and an engine cylinder cover is enlarged by the sliding sleeve, hanging press assembly of a valve oil seal is avoided, the valve guide pipe is effectively protected and is positioned by the positioning rod, so that the stress of the valve oil seal is more uniform in assembly, and damage to the valve oil seal caused by the uneven stress is prevented.

Description

technical field [0001] The invention relates to the field of automobile assembly aids, in particular to a valve oil seal assembly tool. Background technique [0002] The valve oil seal is used for the sealing of the valve guide of the engine cylinder head, which can prevent the oil from entering the intake and exhaust pipes, prevent the mixture of gasoline and air and exhaust gas from leaking, and prevent the engine oil from entering the combustion chamber. The valve oil seal needs to be compatible with gasoline and engine oil at high temperature In contact with each other, its assembly quality affects the performance of the engine as a whole. [0003] Such as figure 1 As shown, the current conventional assembly method of the valve oil seal is to put the valve oil seal 4 on the auxiliary tool 10, and directly press the valve oil seal 4 into the valve guide 3 of the engine cylinder head 2. Since the valve oil seal 4 is a soft material, the part where it is assembled with th...
