Tool for mounting ejector-body

Abstract

The invention discloses a tool for mounting an ejector-body. The tool comprises a handle, wherein a push rod seat which is movably inserted into an inner cavity of the ejector-body is arranged at one end of the handle; a first ejector block and a second ejector block which can move back and forth and are adaptive to the size of an inner hole on the side wall of the ejector-body are arranged on two sides of the push rod seat below the handle; a compression spring is arranged between the first ejector block and the second ejector block; a plug screw which jointly lock the first ejector block, the compression spring and the second ejector block is arranged on the push rod seat located on one side of the second ejector block; and push rods which are connected to the first ejector block and the second ejector block and perpendicularly protrude out of the top of the push rod seat for controlling the first ejector block and the second ejector block to move back and forth are arranged on the first ejector block and the second ejector block, respectively. The tool disclosed by the invention is simple in structure. By designing the push rod seat, which can be inserted into the inner cavity of the ejector-body, with stretchable ejector blocks, the ejector-body is quickly, simply and conveniently mounted by locating by virtue of the ejector blocks and the inner hole on the side of the ejector-body.

Description

technical field [0001] The invention relates to the technical field of engine assembly, more specifically, it relates to a tool for installing tappets. Background technique [0002] The tappet body is an important part of the engine. During the assembly process of the engine, the tappet body is assembled. The existing method is generally to directly take the outer surface of the tappet manually by hand, and manually move it to the tappet installation hole of the cylinder block for assembly. However, before the tappet is assembled, the inside and outside of the entire tappet The surfaces are all filled with lubricating oil, which causes the workers to hold the tappet or the tappet easily slips off the hand and damage the tappet, and it is also difficult to pack the tappet into the cylinder block mounting hole. At the same time, after the tappet body is loaded into the cylinder block mounting hole, the middle hole needs to be aligned with the rib hole on the cylinder block, s...

Problems solved by technology

The existing method is generally to directly take the outer surface of the tappet manually by hand, and manually move it to the tappet installation hole of the cylinder block for assembly. However, before the tappet is assembled, the inside and outside of the entire tappet The surface is filled with lubricating oil, causing workers to be unstable or the tappet is easy to slip off the hand and damage the tappet, and it is also difficult to install the tappet into the mounting hole of the cylinder block

At the same time, after the tappet body is loaded into the cylinder block mounting hole, it is necessary to require the middle hole to be aligned with the rib hole on the cylinder block, so that the tappet body is fixed with screws through the rib hole, because the tappet body is loaded into the cylinder block mounting hole Finally, there are ribs near its periphery, and the installation tools can only be taken out from the top of the tappet body, which has strict requirements on the installation tools, so it has caused great trouble to the installation of the tappet body
