Description

Technical Field

[0001] The utility model relates to the technical field of diesel engine maintenance, in particular to a convenient tool for adjusting valve clearance of a diesel engine. Background Art

[0002] A locomotive, commonly known as a locomotive, is a self-propelled vehicle that pulls or pushes railway vehicles without carrying any commercial load. To ensure stable and reliable operation in good condition, it must undergo planned inspections and maintenance. Valve clearance inspection and adjustment are a crucial component of this maintenance work.

[0003] Currently, when adjusting valve clearance, maintenance personnel are required to use a wrench (fork wrench or ring wrench) in one hand to loosen the valve clearance adjustment nut on the rocker arm, and use a wrench in the other hand to rotate the square head on the top of the valve clearance adjustment bolt to adjust the valve clearance to the appropriate position. Because the two different wrenches are set separately, it is not convenient to use the two wrenches together during maintenance work. On the other hand, the two wrenches can easily separate due to other maintenance work, making it impossible to ensure that they are used in a specific direction, thereby affecting the efficiency of the maintenance work. Utility Model Content

[0004] In order to overcome the above shortcomings, the technical problem to be solved by the present invention is to provide a convenient tool for adjusting the valve clearance of a diesel engine, which integrates two wrenches into one, is easy to operate and use, and is conducive to improving work efficiency.

[0005] In order to solve the above technical problems, the technical solution of the utility model is:

[0006] Diesel engine valve clearance convenient adjustment tool, including:

[0007] An outer sleeve, wherein a first force-applying arm is connected to the outer wall of the outer sleeve, and a guide hole is opened at the center of the bottom of the outer sleeve;

[0008] The inner sleeve is arranged inside the outer sleeve, and the bottom end of the inner sleeve is connected to a guide column that cooperates with the guide hole. The end of the guide column that passes through the guide hole is connected to a second force arm. The inner sleeve is confined in the outer sleeve and can be rotated and lifted relative to the outer sleeve through the action of the second force arm.

[0009] As a preferred technical solution, the first force applying arm and the second force applying arm have different lengths.

[0010] As a preferred technical solution, the length of the first force applying arm is greater than the length of the second force applying arm.

[0011] As a preferred technical solution, the outer sleeve is an outer hexagonal sleeve that is compatible with the valve clearance adjusting nut.

[0012] As a preferred technical solution, the inner sleeve is an outer square sleeve that is compatible with the square head of the valve clearance adjusting bolt.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] (1) Through innovative structural design, the outer sleeve for screwing the valve clearance adjustment nut and the inner sleeve for screwing the valve clearance adjustment bolt are integrated into one body. The two can rotate and rise and fall relative to each other, which greatly improves the convenience of use during maintenance operations. The two integrated socket wrenches will not be separated due to other maintenance operations, which is conducive to improving work efficiency.

[0015] (2) After the outer sleeve and the inner sleeve are assembled, two socket wrenches can be installed on the coaxial valve clearance adjustment nut and valve clearance adjustment bolt at the same time. This makes it very convenient for maintenance personnel to apply force, and only a small amount of force is needed to complete a relatively large amount of work, which greatly improves the convenience of operation.

[0023] The present invention is further described below with reference to the accompanying drawings and examples. In the detailed description that follows, certain exemplary embodiments of the present invention are described by way of illustration only. It goes without saying that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0024] like Figures 1 to 5 As shown, the convenient tooling for adjusting the valve clearance of a diesel engine comprises an outer sleeve 10 and an inner sleeve 20. A first force-applying arm 11 is connected to the outer wall of the outer sleeve 20, and a guide hole 12 is opened at the center of the bottom of the outer sleeve 10. The inner sleeve 20 is arranged inside the outer sleeve 10. A guide post 21 that cooperates with the guide hole 12 is connected to the bottom end of the inner sleeve 20. The end of the guide post 21 that passes through the guide hole 12 is connected to a second force-applying arm 22. The inner sleeve 20 is confined within the outer sleeve 20 and can be rotated and raised relative to the outer sleeve 10 by the action of the second force-applying arm 22. When the second force-applying arm 22 is lifted, the inner sleeve 20 can rise within the outer sleeve 10; when the second force-applying arm 22 is rotated, the inner sleeve 20 can rotate within the outer sleeve 10. In this way, through innovative structural design, the outer sleeve 10 for screwing the valve clearance adjustment nut and the inner sleeve 20 for screwing the valve clearance adjustment bolt are integrated into one, and the two can rotate and rise and fall relative to each other. During maintenance operations, the two can be freely connected to the valve clearance adjustment nut 31 and the valve clearance adjustment bolt 32 respectively, which greatly improves the ease of use during maintenance operations. The two integrated socket wrenches will not be separated due to other maintenance operations, which is conducive to improving work efficiency.

[0025] In order to facilitate maintenance personnel to hold and operate, the lengths of the first force applying arm 11 and the second force applying arm 22 are different. The length of the first force applying arm 11 is preferably greater than that of the second force applying arm 22, so that force application is more convenient.

[0026] refer to Figure 2 and Figure 6 In this embodiment, the outer sleeve 10 is an outer hexagonal sleeve adapted to the valve clearance adjustment nut 31 . The inner sleeve 20 is an outer square sleeve adapted to the square head 33 of the valve clearance adjustment bolt 32 .

[0027] refer to Figure 6The method of use is as follows: first, the outer sleeve 10 is sleeved onto the valve clearance adjustment nut 31 of the rocker arm 30, then the second force arm 22 is rotated or raised and lowered to adjust the inner sleeve 20 so that the inner sleeve 20 is sleeved onto the square head 33 of the valve clearance adjustment bolt 32. After rotating the first force arm 11 with one hand and loosening the valve clearance adjustment nut 31 with the outer sleeve 10, the second force arm 22 is rotated with the other hand and the valve clearance adjustment bolt 32 is rotated with the inner sleeve 20 to adjust the valve clearance to the appropriate distance. By fitting the outer sleeve 10 and the inner sleeve 20 together, two socket wrenches can be installed simultaneously on the coaxial valve clearance adjustment nut 31 and valve clearance adjustment bolt 32. This makes it very convenient for maintenance personnel to apply force, and only a small amount of force is required to complete a relatively large amount of work, greatly improving the convenience of operation.

[0028] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
