[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Please refer to the following Figure 1-2 A cross pin installation tool 100 according to an embodiment of the present invention is described.

[0026] Reference Figure 1 and Figure 2 According to the cross pin installation tool 100 of the embodiment of the utility model, a cross pin hole 210 and a connecting rod installation hole 220 are provided in the cross head 200, the cross pin hole 210 intersects and communicates with the connecting rod installation hole 220, the connecting rod 300 is penetrated in the connecting rod installation hole 220, and one end of the connecting rod 300 extends into the connecting rod installation hole 220 (such as Figure 2 The left end of the connecting rod 300 shown in the figure is provided with a fixing hole (not shown in the figure) suitable for the cross pin to pass through.

[0027] The cross pin installation tool 100 comprises: a body 10, the body 10 is adapted to the shape of the cross pin hole 210 and is suitable for extending into the cross pin hole 210, and the body 10 has an axial direction (such as Figure 1 The first end 11 and the second end 12 are relatively arranged in the up and down direction (as shown in the figure), the first end 11 is the insertion end of the body 10, and the cross-sectional size of the first end 11 gradually decreases in the direction from the second end 12 to the first end 11.

[0028] For example, Figure 1 and Figure 2 As shown, the cross pin hole 210 extends in the up-down direction, the connecting rod mounting hole 220 extends in the left-right direction, the lower end of the body 10 is the first section, and the upper end of the body 10 is the second end 12.

[0029] When using the cross pin installation tool 100 to assist in the installation of the cross pin, first extend the left end of the connecting rod 300 into the connecting rod installation hole 220, then insert the first end 11 of the cross pin installation tool 100 from the upper end of the cross pin hole 210 into the cross pin hole 210, then the cross pin installation tool 100 passes through the fixing hole, and then the first end 11 passes out from the lower end of the cross pin hole 210, finally, use the cross pin to push the cross pin installation tool 100 out of the cross pin hole 210 from the lower end of the cross pin hole 210, at this time, the installation of the cross pin is completed.

[0030] The cross pin installation tool 100 of the utility model is provided with a first end 11, and the cross-sectional dimension of the first end 11 is smaller than the cross-sectional dimension of the cross pin hole 210, so that the cross pin installation tool 100 can be conveniently passed through the cross pin hole 210 and the fixing hole. Compared with the solution in the prior art that directly installs the cross pin into the cross pin hole 210, which makes the installation of the cross pin difficult, the cross pin installation tool 100 of the present application can reduce the difficulty of installing the cross pin installation tool 100 into the cross pin hole 210. In the process of using the cross pin to push the cross pin installation tool 100 out of the cross pin hole 210, there is no need to consider whether the fixing hole is directly opposite to the cross pin hole 210, so that the installation difficulty of the cross pin can be reduced, the installation time can be saved, and the installation efficiency can be effectively improved.

[0031] According to the cross pin installation tool 100 of the embodiment of the utility model, a first end 11 is provided, and the first end 11 can reduce the difficulty of installing the cross pin installation tool 100 to the cross pin hole 210, thereby reducing the difficulty of installing the cross pin, saving installation time, and further improving installation efficiency.

[0032] Furthermore, if Figure 1 and Figure 2 As shown, before using the cross pin installation tool 100 to assist in the installation of the cross pin, lubricant is first applied to the cross pin hole 210, the first end 11 and the fixing hole, so that the cross pin installation tool 100 can smoothly penetrate into the cross pin hole 210 and the fixing hole. After the lubricant is applied, the end of the connecting rod 300 with the fixing hole is inserted into the connecting rod installation hole 220 using a turning wheel, so that the fixing hole and the cross pin hole 210 are roughly in the same vertical plane, and then the cross pin installation tool 100 is used to pass through the cross pin hole 210 and the fixing hole in sequence, and the connecting rod 300 is fixed in the crosshead 200.

[0033] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 The outer peripheral surface of the first end 11 is formed into a conical surface, and the angle between the conical surface and the vertical direction is 15°-20°. In this way, it can be avoided that the angle between the conical surface and the vertical direction is too small, which makes it difficult for the first end 11 to enter the cross pin hole 210, so as to ensure that the first end 11 can smoothly enter the cross pin hole 210. At the same time, it can be avoided that the angle between the conical surface and the vertical direction is too large to affect the strength of the first end 11. When the cross pin abuts against the first section to push out the cross pin installation tool 100, the angle of the conical surface is limited, which can effectively prevent the first end 11 from being deformed and damaged.

[0034] For example, Figure 1 and Figure 2 As shown, the angle between the cone surface and the vertical direction is 15°, 16°, 17°, 18°, 19° or 20°.

[0035] According to some embodiments of the present invention, referring to Figure 2 , the body 10 is one end (such as Figure 2 The first end 11 of the main body 10 is open. Thus, the weight of the main body 10 can be reduced, and the cross pin installation tool 100 can be easily taken.

[0036] According to some optional embodiments of the present invention, referring to Figure 2The wall thickness of the body 10 is 10 mm to 20 mm. Thus, the weight of the cross pin installation tool 100 may be increased due to the wall thickness of the body 10 being too thick, thereby ensuring the portability of the cross pin installation tool 100. At the same time, the strength of the cross pin installation tool 100 may be affected due to the wall thickness of the body 10 being too thin.

[0037] For example, Figure 2 As shown, the wall thickness of the body 10 can be 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm or 20 mm.

[0038] According to some embodiments of the present invention, referring to Figure 2 , the length of the body 10 is greater than or equal to the length of the cross pin hole 210. Thus, it can be ensured that the body 10 can completely penetrate the cross pin hole 210, so that the cross pin installation tool 100 can fix the connecting rod 300 in the cross pin hole 210.

[0039] Preferably, the ratio of the length of the main body 10 to the length of the cross pin hole 210 is 1:1-1:1.5, which can ensure that the main body 10 of the cross pin installation tool 100 can completely penetrate the cross pin hole 210.

[0040] According to some embodiments of the present invention, referring to Figure 2 The cross pin installation tool 100 includes a gripping portion 20 connected to the second end 12 of the body 10. Thus, the gripping portion 20 can facilitate the cross pin installation tool 100 to be taken, so that the cross pin installation tool 100 can be easily installed in the cross pin hole 210. For example, Figure 2 As shown, the grip portion 20 is connected to the upper end of the body 10 .

[0041] According to some optional embodiments of the present invention, referring to Figure 2 The diameter of the gripping portion 20 is smaller than the diameter of the body 10. Thus, it is possible to avoid the gripping portion 20 having an excessively large diameter that affects the taking, thereby further facilitating the taking of the cross pin installation tool 100.

[0042] According to some optional embodiments of the present invention, referring to Figure 2 A weight-reducing hole 21 is provided in the gripping portion 20. Thus, the weight of the gripping portion 20 can be reduced, thereby reducing the weight of the cross pin installation tool 100, and further facilitating the taking of the cross pin installation tool 100.

[0043] According to some optional embodiments of the present invention, referring to Figure 2The weight-reducing hole 21 penetrates the gripping portion 20 in the direction from the gripping portion 20 to the body 10. Thus, the weight of the cross pin installation tool 100 can be reduced to a weight suitable for handling, thereby reducing the labor intensity of the workers. Figure 2 As shown, the weight-reducing hole 21 passes through the entire grip portion 20 in the up-down direction.

[0044] According to some embodiments of the present invention, referring to Figure 2 The cross pin installation tool 100 is a cast aluminum part. Thus, it is possible to avoid the cross pin installation tool 100 being too heavy to affect the taking of the cross pin installation tool 100, and at the same time, the strength of the cross pin installation tool 100 can be ensured, effectively preventing the cross pin installation tool 100 from being damaged.
