Abstract

The invention discloses a camshaft bush installation tool of a heavy-duty diesel engine. The camshaft bush installation tool of the heavy-duty diesel engine comprises a pressure lever and a guide sleeve sheathed with the pressure lever, wherein the pressure lever comprises a joint, a plunger chip, and a connecting pipe used for connecting the joint and the plunger chip, the joint is provided with a bush positioning part, and one end of the plunger chip is provided with a backstop bulge and a guide key arranged in a guide key slot extending along the axial direction; and the guide sleeve is internally provided with a guide slot, the pressure lever penetrates in the guide sleeve, and the guide key of the plunger chip extends into the guide slot of the guide sleeve, and is spaced by the backstop bulge. The installation phase and the installation depth of a camshaft bush on the diesel engine can be ensured by virtue of the camshaft bush installation tool of the heavy-duty diesel engine, so that the structure can greatly enhance the installation precision of the camshaft bush on the diesel engine, reduce the repeated operation and the camshaft bush scraped due to the poor installation precision of the camshaft bush, reduce the production cost and enhance the production efficiency.

Description

technical field [0001] The invention relates to the field of heavy-duty diesel engines, in particular to a camshaft bushing installation tool for heavy-duty diesel engines. Background technique [0002] In the field of diesel engine manufacturing, especially in the manufacture of heavy-duty diesel engines, due to the particularity of the structure of the side-mounted camshaft, there is no special, large-scale camshaft bushing press-fitting equipment, usually by means of a hydraulic Rama device (not shown in the figure), The labor intensity of the producer can be greatly reduced, but the installation accuracy of the camshaft bushing 6, including the installation phase and installation depth of the camshaft bushing on the diesel engine body, depends entirely on the individual skill level of the producer. Moreover, two producers are required to cooperate with each other, one of them operates the hydraulic puller to control the installation depth of the camshaft bushing 6 on the...
