The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model. In the following paragraphs, the present utility model will be described more specifically by way of example with reference to the attached drawings. The advantages and features of the present utility model will be clearer according to the following description and the claims. It should be noted that the attached drawings are all in a very simplified form and use non - precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present utility model.
[0024] Please refer to Figure 1 and Figure 2 , an embodiment of the present application discloses a connecting rod body fixing tool, which is used in cooperation with the frame 200 to fix the connecting rod body. It includes parallel support rods 100. The support rods 100 are strip - shaped with a square cross - section. The upper surface of the support rod 100 is fixedly connected with a rod body locking structure 300 to lock the position of the rod body. When in use, the two support rods 100 pass through the frame camshaft cover hole 210 and are installed in the frame 200. The position of the rod body locking structure 300 corresponds to the position of the rod body and limits the position of the rod body, avoiding the situation that the rod body shakes relative to the frame and the connecting rod collides with the parts in the diesel engine frame, effectively improving the safety of the operator during the inspection and maintenance process.
[0025] Specifically, the rod body locking structure 300 includes a first locking portion 310 and a second locking portion 320. The first locking portion 310 has a first semi-circular cavity 311. On the opposite sides of the first semi-circular cavity 311, there are integrally connected first fixing portions 312 extending towards the distal end. The first fixing portions 312 on both sides are fixedly connected to the corresponding support rod 100 on the corresponding side. The second locking portion 320 has a second semi-circular cavity 321 corresponding to the semi-circular cavity 311 of the first locking portion. On the opposite sides of the second semi-circular cavity 321, there are integrally connected second fixing portions 322 extending towards the distal end. The second fixing portions 322 are fixedly connected to the first fixing portions 312. The first semi-circular cavity 311 and the second semi-circular cavity 321 are buckled with their openings facing each other to form a locking space with a closed circumferential surface. The rod body is located within this locking space to achieve the limiting effect on the rod body. Preferably, the first fixing portion 312 is a long strip-shaped plate, which has through holes penetrating the upper and lower end faces. Corresponding through holes are also provided at the corresponding positions of the corresponding support rod 100. The fixing rod penetrates through each through hole from top to bottom to achieve the fixation of the support rod 100 and the first fixing portion 312. The best through holes are screw holes, and the fixing rod is a threaded rod matching with the screw holes. As common parts, they are convenient for connection and fixation, and also convenient for disassembly and replacement. On one side surface of the first fixing portion 312, there is also formed an inwardly concave notch for accommodating the second fixing portion 322. The second fixing portion 322 is also a long strip-shaped plate, with a length shorter than that of the first fixing portion 312. It is embedded in the notch formed on one side surface of the first fixing portion 312, and then the two are fixedly connected by bolts and nuts. By rotating the position of the nut on the bolt, the area of the locking space formed by the two semi-circular cavities is adjusted to ensure that the inner walls of the two semi-circular cavities are both in contact with the outer wall of the rod body.
[0026] To adapt to various lengths of the rod body, sleepers 400 with lengths and cross-sections corresponding to them are laid on the upper surface of the support rod 100. The rod body locking structure 300 is arranged on the upper surface of the sleepers 400. To fix the rod body locking structure 300, the sleepers 400 are also provided with through holes penetrating the upper and lower end faces. Sleepers 400 with appropriate thicknesses are selected according to the length of the rod body.
[0027] To achieve the fixation of the support rod 100 and the frame 200, baffles 110 are integrally connected to both ends of the support rod 100. After the support rod 100 penetrates through the camshaft door hole 210 of the frame, the inner opposite surfaces of the baffles 110 at both ends of the support rod 100 are respectively in contact with the outer surface of the corresponding side of the frame 200 and are fixed by bolts, further enhancing the connection stability between the support rod 100 and the frame 200.
[0028] Installation process of the utility model: First, two support rods 100 pass through the camshaft door cover holes 210 of the frame and are installed in the frame 200. The position of the mounting holes of the baffle 110 is adjusted to align with the bolt holes of the camshaft door cover of the frame, and they are fixedly connected by bolts to fix the position of the support rods 100. Subsequently, depending on the height of the rod body, it is determined whether sleepers 400 are needed. If so, the two sleepers 400 are placed on the support rods 100. At the same time, the positioning bolts sequentially penetrate the corresponding through holes from top to bottom to fix the first locking part 310 on the upper surface of the sleeper 400.
[0029] First, the first semi-circular cavity 311 of the first locking part 310 is brought into contact with the outer wall of the connecting rod body 12. Subsequently, the second locking part 320 is installed, and the connection state between the second fixing part 322 and the first fixing part 321 is adjusted to adjust the fitting state of the second semi-circular cavity 321 and the connecting rod body until they are completely fitted, thereby realizing the limitation of the connecting rod body.
[0030] As mentioned above, it is only the preferred embodiment of the utility model and does not impose any form of limitation on the utility model. Any ordinary technician in the industry can smoothly implement the utility model as shown in the accompanying drawings of the specification and described above. However, any minor changes, modifications, and equivalent variations made by those skilled in the art within the scope of the technical solution of the utility model by using the technical content disclosed above are equivalent embodiments of the utility model. At the same time, any equivalent changes, modifications, and variations made to the above embodiments based on the essential technology of the utility model still fall within the protection scope of the technical solution of the utility model.
