Description

Technical Field

[0001] This utility model relates to the field of tooling technology, and more specifically, to a tooling for striking an oil dipstick sleeve. Background Technology

[0002] When installing the oil dipstick sleeve on an engine, a portion of the sleeve needs to be driven into the cylinder block. Because the middle part of the dipstick sleeve is bent, the current method for installing the engine oil dipstick sleeve is as follows: the production worker first gently taps the dipstick sleeve onto the engine cylinder block with a hammer, then uses an iron rod longer than the dipstick sleeve to push against the step of the dipstick sleeve and taps it with a hammer until the required portion of the dipstick sleeve is completely driven into the cylinder block.

[0003] Because the stepped surface of the dipstick sleeve is only about 1cm wide, when using an iron bar to strike it, the striking surface needs to be frequently changed to ensure that the dipstick sleeve does not shift in one direction. During operation, because the assembler can only use one hand to hold the dipstick sleeve and the iron bar, and the dipstick sleeve and the iron bar are separate, this leads to inaccurate striking, difficult operation, low assembly efficiency, greatly increasing the labor intensity of the assembler, seriously affecting the production cycle, impacting production efficiency, and even posing a risk of damaging the cylinder block due to misalignment of the dipstick sleeve. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tooling for hammering oil dipstick sleeves to address the above-mentioned shortcomings of the prior art, so as to ensure that the step surface of the oil dipstick sleeve is subjected to uniform force during the hammering process, reduce the deformation of the oil dipstick sleeve or cylinder body, and improve production efficiency.

[0005] The technical solution of this utility model is as follows: a tool for striking an oil dipstick sleeve includes a tube body. The lower part of the tube body is provided with a relief groove that is radially recessed from one side to the other. The relief groove has a U-shaped cross-section and the top of the relief groove is an inclined surface. The bottom of the relief groove extends to the bottom end face of the tube body. The middle part of the relief groove is provided with a through hole that penetrates to the other side wall of the tube body. The top of the through hole is connected to the lowest point of the inclined surface. The bottom of the through hole extends to the lower part of the relief groove and forms a limiting block at the lower part of the tube body. The width of the through hole and the relief groove are both adapted to the diameter of the oil dipstick sleeve.

[0006] As a further improvement, the tube body is a cylinder, and the upper part of the tube body is a solid cylinder.

[0007] Furthermore, the inner wall of the limiting block is provided with a groove, and a magnet is provided in the groove.

[0008] Furthermore, the outer wall surface of the tube is provided with anti-slip texture.

[0009] Furthermore, the bottom of the tube is provided with a settling groove, the diameter of which is adapted to the diameter of the stepped surface of the oil dipstick sleeve.

[0010] Furthermore, the outer wall surface of the tube is plated with nickel.

[0011] Beneficial effects

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] This utility model provides a hammering fixture for oil dipstick sleeves to ensure uniform force distribution on the stepped surface of the dipstick sleeve during hammering, reduce deformation of the dipstick sleeve or cylinder body, and improve production efficiency.

[0016] Among them: 1-pipe body, 2-through hole, 3-gap groove, 4-limiting block, 5-inclined surface, 6-sinking groove. Detailed Implementation

[0017] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0018] See Figure 1-2A tool for striking an oil dipstick sleeve includes a tube body 1. The lower part of the tube body 1 has a relief groove 3 that is radially recessed from one side to the other. The relief groove 3 has a U-shaped cross-section, and its top end is an inclined surface 5. The bottom end of the relief groove 3 extends to the bottom end face of the tube body 1. A through hole 2 is provided in the middle of the relief groove 3, penetrating to the other side wall of the tube body 1. The top end of the through hole 2 connects to the lowest point of the inclined surface 5, and the bottom end of the through hole 2 extends to the relief groove 3. The lower part of the tube body 1 forms a limiting block 4, which limits the oil dipstick sleeve to prevent it from shifting during impact. The widths of the through hole 2 and the relief groove 3 are adapted to the diameter of the oil dipstick sleeve. The through hole 2 and the oil dipstick sleeve are interference fit. When the oil dipstick sleeve passes through the through hole 2, it can restrict the oil dipstick sleeve to a certain extent, preventing the oil dipstick sleeve from shifting with the tube body 1 during impact. Regarding the position; during use, first, pass the curved part of the dipstick sleeve through the through hole 2, then install the straight part of the dipstick sleeve in the relief groove 3, and then install the limiting block 6 at the bottom of the relief groove 3 to limit the dipstick sleeve and prevent it from shifting during the hammering process. At this time, by limiting both ends of the straight part of the dipstick sleeve, relative sliding between the dipstick sleeve and the tube body 1 is prevented during the installation and hammering process. Then, the operator holds the tube body 1 with one hand and uses a hammer or other tool to hammer the tube body 1 with the other hand. Preferably, a hammering part with a diameter larger than the tube body 1 can be set at the top of the tube body 1 to increase the hammering area and make it easier for the operator to hammer the tube body 1. This tooling ensures that the stepped surface of the dipstick sleeve is subjected to uniform force during the hammering process, reduces the deformation of the dipstick sleeve or cylinder body, and improves production efficiency.

[0019] In this embodiment, the tube body 1 is a cylinder, and the upper part of the tube body 1 is a solid cylinder. During the installation process, the operator uses tools such as a hammer to strike the top of the tube body 1. The upper part of the tube body 1 is a solid cylinder, which effectively strengthens its overall structure.

[0020] In this embodiment, the inner wall of the limiting block 4 is provided with a groove, and a magnet is provided in the groove. The oil dipstick sleeve is magnetic and attracts each other when in contact with the magnet, thereby playing a certain limiting role for the oil dipstick sleeve.

[0021] In this embodiment, the outer wall surface of the tube body 1 is provided with anti-slip texture to increase the roughness of the outer wall surface of the tube body 1, thereby improving the stability of the operator's hand when holding the tube body 1.

[0022] In this embodiment, the bottom of the tube body 1 is provided with a recessed groove 6. The diameter of the recessed groove 6 is adapted to the diameter of the stepped surface of the oil dipstick sleeve. The diameter of the recessed groove 6 is equal to the diameter of the stepped surface of the oil dipstick sleeve, which serves as a positioning effect.

[0023] In this embodiment, the outer wall of the tube body 1 is plated with nickel. Nickel plating can form a strong protective layer on the surface of the tube body 1 to prevent the tube body 1 from being corroded. At the same time, it makes the surface of the tube body 1 bright and flawless, improving its appearance. In addition, nickel plating can also increase the surface hardness of the tube body 1, improve its wear resistance and abrasion resistance, thereby enhancing the service life of the tube body 1.

[0024] 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.
