Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and more specifically, to an engine valve clearance adjustment assembly tool. Background Technology

[0002] When the engine is running, the valves expand due to the increase in temperature. If there is no clearance or the clearance is too small between the valves and their transmission components when they are cold, the thermal expansion of the valves and their transmission components when they are hot will inevitably cause the valves to not close tightly, resulting in air leakage during the compression and power strokes. This will reduce the engine's power and, in severe cases, even make the engine difficult to start. To eliminate this phenomenon, a clearance is usually left between the valves and their transmission components when the engine is cold to compensate for the expansion of the valves after heating. This clearance is called valve clearance. Therefore, adjusting the engine valve clearance is an important task in the engine assembly process.

[0003] Traditional valve clearance adjustment methods typically require frequent changes of valve adjustment tools depending on the size of the adjusting screw, which is complex and time-consuming. Furthermore, traditional methods rely on the operator's experience and feel, making it difficult to guarantee adjustment accuracy. Utility Model Content

Both ends of the adjustment handle are provided with adjustment screws. A cone is provided between the adjustment screws and the adjustment handle. The outer wall surfaces of both ends of the adjustment handle are hexagonal structures. The adjustment wrench includes a ratchet sleeve and a torque wrench. The ratchet sleeve is detachably mounted on one end of the torque wrench. The upper part of the inner wall of the ratchet sleeve has an inner hexagonal structure adapted to the hexagonal structure, and the lower part of the inner wall of the ratchet sleeve has a conical surface adapted to the outer wall surface of the cone. The ratchet sleeve is movably sleeved on the adjustment handle.

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0024] See Figure 1-7 An engine valve clearance adjustment tool includes an adjustment handle 1 and an adjustment wrench 2. Both ends of the adjustment handle 1 are equipped with adjustment screws 3, with different screw diameters corresponding to the two adjustment screws 3, thus expanding the applicability of the valve clearance adjustment tool. A conical body 4 is provided between the adjustment screws 3 and the adjustment handle 1. The outer walls of both ends of the adjustment handle 1 are hexagonal structures 5. The adjustment wrench 2 includes a ratchet sleeve 21 and a torque wrench 22. The ratchet sleeve 21 is detachably mounted on one end of the torque wrench 22. The upper part of the inner wall of the ratchet sleeve 21 is provided with... The inner hexagon on the inner wall of the ratchet sleeve 21 conforms to the hexagonal structure 5, preventing slippage when the adjusting handle 1 is rotated. The lower part of the inner wall of the ratchet sleeve 21 is provided with a conical surface that conforms to the outer wall surface of the cone 4. The ratchet sleeve 21 is movably fitted on the adjusting handle 1. When the ratchet sleeve 21 is fitted on the adjusting handle 1, the conical surface of the lower part of the ratchet sleeve 21 is in contact with the surface of the cone 4, which limits the movement of the ratchet sleeve 21 and prevents the ratchet sleeve 21 from moving upward.

[0025] When adjusting the valve clearance, the ratchet sleeve 21 is fitted onto the adjusting handle 1, so that the outer wall of the hexagonal structure 5 and the cone 4 on the adjusting handle 1 fits against the inner wall of the ratchet sleeve 21. Then, the adjusting screw 3 at one end of the adjusting handle 1 is inserted into the screw at the top of the valve stem. At this time, the operator holds the adjusting handle 1 with one hand and holds the adjusting wrench 2 with the other hand, turning the adjusting wrench 2 back and forth to tighten or loosen the screw at the top of the valve stem, thereby completing the adjustment of the valve clearance. At the same time, a measuring plate 6 can be placed between the valve stem 17 and the transmission component 18. When the measuring plate 6 is adjusted so that both sides of it are in contact with the valve stem 17 and the transmission component 18 respectively, the valve clearance is adjusted to the required level. The combination tool in this application has the advantages of simple structure, lightweight tooling, and convenient manual valve clearance adjustment operation. It also has a brake component that is compatible with various adjusting screw structures, which can meet the valve clearance adjustment requirements, reduce tool replacement, and effectively improve efficiency.

[0026] In this embodiment, a mounting block 11 is provided on the outer wall surface of the ratchet sleeve 21, and a mounting groove 12 adapted to the mounting block 11 is provided at one end of the torque wrench 22. The mounting block 11 is movably inserted into the mounting groove 12, and the depth of the mounting groove 12 is adapted to the height of the mounting block 11.

[0027] In this embodiment, a through hole 13 is provided on the side wall of the mounting groove 12, and a threaded hole is provided on the side of the mounting block 11. A fastening bolt 15 is movably inserted into the through hole 13, and the fastening bolt 15 is threadedly connected to the threaded hole. The diameter of the through hole 13 is larger than the diameter of the threaded hole. The mounting block 11 is inserted into the mounting groove 12, and the fastening bolt 15 passes through the through hole 13 and is threadedly connected to the threaded hole, thereby mounting the ratchet sleeve 21 on the torque handle 22.

[0028] Furthermore, through holes 13 can be provided on both sides of the inner wall of the mounting groove 12, and threaded holes 14 can be provided on both sides of the mounting block 11 to further improve the stability between the ratchet sleeve 21 and the torque handle 22.

[0029] In this embodiment, anti-slip textures are provided on the outer wall surfaces of the torque wrench 22 and the adjusting handle 1 to increase the friction of the outer wall surfaces of the torque wrench 22 and the adjusting handle 1, and to prevent the operator from slipping when adjusting the valve clearance.

[0030] Furthermore, one end of the torque wrench 22 is a cuboid structure, and the ratchet sleeve 21 is mounted on the cuboid structure. The other end of the torque wrench 22 is a cylinder with anti-slip texture on its circumferential surface. Setting one end of the torque wrench 22 as a cuboid structure can reduce the overall weight of the torque wrench 22 and make it easier for workers to use.

[0031] In this embodiment, the engine valve clearance adjustment tool also includes a measuring device, which includes multiple measuring plates 6 and a protective shell 7. The protective shell 7 is U-shaped, and the multiple measuring plates 6 are rotatably installed inside the protective shell 7. The protective shell 7 can protect the measuring plates 6 inside. When adjusting the engine valve clearance, the measuring plates 6 can be placed between the valve stem 17 and the transmission component 18 to facilitate the adjustment of the valve clearance. The distance between the valve stem 17 and the transmission component 18 can also be measured by the measuring plates 6.

[0032] In this embodiment, a rotating shaft 10 is provided at one end of the protective shell 7. Multiple measuring plates 6 are rotatably mounted on the rotating shaft 10. A clamping nut 8 is threadedly connected to the rotating shaft 10 above the protective shell 7. When the operator rotates the multiple measuring plates 6 out of the protective shell 7 and forms the required thickness, the clamping nut 8 can be tightened to clamp the protective shell 7 and the measuring plates 6, thereby fixing the measuring plates 6 and preventing them from rotating during the measurement process.

[0033] In this embodiment, an arc-shaped groove 9 is provided on the top side of the protective shell 7, which makes it easy for the staff to rotate the measuring piece 6 inside the protective shell 7 through the arc-shaped groove 9.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
