Embodiment

[0032] see figure 1 , the present invention provides a technical solution: a pressing tool for positioning pin sleeves, including a connecting mechanism 100 and a supporting mechanism 200 .

[0033] see figure 2 , the connecting mechanism 100 includes a connecting rod 110 and a screw 120 , the bottom of the connecting rod 110 is provided with a slide rail 111 , the screw 120 is fixedly mounted on the bottom of the connecting rod 110 , and the screw 120 is provided with an external thread portion 121 .

[0034] In some specific embodiments, the connecting mechanism 100 further includes a washer 130, which is arranged on the top of the connecting rod 110, so as to prevent the positioning pin sleeve from directly pressing the connecting rod 110 to cause deformation of the tool and affect the adjustment accuracy of the effective height of the tool.

[0035] In some specific embodiments, the connecting rod 110 is provided with a suspension hole 112, and the suspension hole 112 is...

Abstract

The invention provides a press fitting tool for a positioning pin bush, and belongs to the technical field of engine assembly. The press fitting tool for the positioning pin bush comprises a connecting mechanism and a supporting mechanism, wherein a screw is fixedly installed at the bottom of a connecting rod, the screw is provided with an external thread part, an internal thread part is arranged on the inner wall of a sleeve rod, the internal thread part is in clearance fit with the external thread part, a limiting ring is fixedly installed on the top of the sleeve rod, the two ends of a second spring are fixedly installed on the limiting ring and a mounting plate respectively, a first rolling steel ball is rotatably installed on the mounting plate, and the first rolling steel ball is in clearance fit with the sliding rail. According to the press fitting tool for the positioning pin bush, the effective mounting height is flexibly adjusted, meanwhile, the stability of the tool structure is guaranteed, meanwhile, the depth of a cylinder cover positioning pin hole is not changed, it is directly guaranteed that the height of the pressing positioning sleeve meets the use requirement, and positioning errors are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of engine assembly, in particular to a pressing tool for positioning pin sleeves. Background technique [0002] With the advent of overhead valve engines, cylinder head covers were first introduced in the 1920s and 1930s. The first and most basic function of the cylinder head cover is to cover and seal the cylinder head, keeping the oil inside while keeping the Contaminants such as dirt and moisture are isolated from the outside. The second function of the cylinder head cover is to isolate the oil from the air. During the operation of the engine, an oil mist is formed. The cooler inner surface of the cylinder head cover will collect the oil mist. Make the engine oil condense and flow down to the oil casing. When installing the cylinder head cover, use the positioning pin sleeve for positioning installation. At the same time, the positioning pin sleeve must ensure the effective height of the positioning of th...
