Abstract
The utility model relates to a kind of engine valve oil seal correcting tool, comprise depression bar, one end of described depression bar is provided with bulb, its other end is provided with the inside axially extended pilot hole from end face center, the bar portion of described pilot hole and valve is slidably matched, the opening part of described pilot hole is provided with the bellmouth coaxial with it, and the larger one end of described bellmouth diameter outwardly.The utility model can realize the Fast Correction of valve oil seal, is supplementing existing equipment and technique, easy to operate, quick, has ensured the continuity of producing, has improved the reliability of product.
Description
Technical field
The utility model relates to the aid in engine cylinder cover general assembly process, is specifically related to a kind of engine valve oil seal correcting tool.
Background technology
When engine cylinder cover general assembly, need valve oil seal to be press fit on valve guide bushing.Current assembling mode is that valve oil seal is positioned on valve guide bushing by operator, then press-fits with install machinery.Install machinery no doubt can improve installation effectiveness, but the situation that the situation that the valve oil seal using install machinery None-identified to occur in batch production process is not press-fit into place, the valve oil seal caused because of valve stem resistance when valve assembles exit slightly, finally can cause engine burn oil even to damage the serious consequences such as engine.
Utility model content
A kind of engine valve oil seal correcting tool of the purpose of this utility model, whether this correcting tool convenient, reliably can correct engine valve oil seal and be seated.
A kind of engine valve oil seal correcting tool described in the utility model, comprise depression bar, one end of described depression bar is provided with bulb, its other end is provided with the inside axially extended pilot hole from end face center, the bar portion of described pilot hole and valve is slidably matched, the opening part of described pilot hole is provided with the bellmouth coaxial with it, and the larger one end of described bellmouth diameter outwardly.
Adopt technique scheme, after install machinery automatic press mounting valve oil seal, operator is while installation valve, the Fast Correction of valve oil seal is carried out by the bellmouth on correcting tool, now pilot hole coordinates with the bar portion of valve the effect playing location, bellmouth coordinates with the taper surface on valve oil seal, to realize the Fast Correction of valve oil seal, arranges bulb handled easily person by holding this correcting tool.This correcting tool structure is simple, easy to operate, quick, contributes to reducing even avoiding putting in place because valve oil seal is unassembled, fill partially, the engine damage caused such as damaging by pressure.
Further, the opening part of described pilot hole is provided with the installing hole coaxial with it, described installing hole is equipped with the briquetting of ring-type by the mode of interference fit, described bellmouth is extended internally by the outer face of briquetting, and described bellmouth is communicated with described pilot hole and the diameter of its minimum diameter and described pilot hole is identical.
Further, described briquetting is made of plastics.The briquetting that plastics are made can not cause damage to valve oil seal.
Further, the drift angle of described bellmouth is 120 °.
The utility model can realize the Fast Correction of valve oil seal, is supplementing existing equipment and technique, easy to operate, quick, has ensured the continuity of producing, has improved the reliability of product.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of engine valve oil seal correcting tool as shown in Figure 1, comprise depression bar 7, one end of depression bar 7 is provided with bulb 6, its other end is provided with the inside axially extended pilot hole 8 from end face center, pilot hole 8 is slidably matched with the bar portion of valve 5, the opening part of pilot hole 8 is provided with the bellmouth 9 coaxial with it, and the larger one end of bellmouth 9 diameter outwardly.Concrete, the opening part of pilot hole 8 is provided with the installing hole 10 coaxial with it, installing hole 10 is equipped with the briquetting 11 of ring-type by the mode of interference fit, bellmouth 9 is extended internally by the outer face of briquetting 11, and bellmouth 9 is communicated with pilot hole 8 and the diameter of its minimum diameter and pilot hole 8 is identical.Briquetting 11 is made of plastics.The drift angle of bellmouth 9 is 120 °.
As shown in Figures 2 and 3, the operation principle of correcting tool 1 described in the utility model is: after install machinery automatic press mounting valve oil seal 2, and operator, while installation valve 5, carries out the Fast Correction of valve oil seal 2 by the bellmouth 9 on correcting tool 1.Now, valve 5 is through valve guide bushing 3 and valve oil seal 2, valve oil seal 2 is enclosed within valve guide bushing 3, pilot hole 8 coordinates with the bar portion of valve 5 effect playing location, bellmouth 9 coordinates with the taper surface of valve oil seal 2 one end, the other end and the engine cylinder cover 4 of valve oil seal 2 are conflicted, and promote correcting tool 1 to realize the Fast Correction of valve oil seal 2.
