Problems solved by technology

[0002] In the production process of the engine body, there is a process of press-fitting the camshaft bushing, that is, to press the camshaft bushing into the specified position of the camshaft bottom hole of the engine body. In the past, the camshaft bushing was mostly pressed manually. The hammer strikes the mandrel for assembly. The installation phase and installation depth of the camshaft bushing on the cylinder block rely on human control and lack a limit device. It is difficult to guarantee the installation accuracy of the camshaft bushing on the cylinder block. The installation accuracy of the shaft bushing is poor; in addition, the installation of the camshaft bushing requires the cooperation of two producers. After these camshaft bushings are taken out of the diesel engine body with special tooling, they will be scrapped and cannot be reused. They must be reinstalled with new camshaft bushings. The entire installation process is time-consuming and labor-intensive, and the installation efficiency is low.

Abstract

The invention discloses a cylinder body lining assembling tool which comprises an assembling pull rod. The assembling pull rod comprises a stepped shaft and a plurality of limiting sleeves. The stepped shaft comprises a plurality of shaft bodies with the diameters gradually decreased. The axial lengths of the shaft bodies are matched with the distance between limiting baffles of a corresponding cylinder body cam shaft hole. The diameter difference value of every two adjacent shaft bodies is 2-6 mm. The limiting sleeves are located on the corresponding shaft bodies. The top of the stepped shaft is provided with a positioning end face. The positioning end face is provided with a positioning pin. The tail end of the stepped shaft is provided with a connection rod with a pin hole. According to the assembling tool, the stepped shaft and the limiting sleeves matched with the shaft bodies of the stepped shaft are adopted, hydraulic equipment is utilized for completing installation of all linings in one cam shaft hole at a time, operation is efficient, and the precision is high.
