AI Technical Summary

Technical Problem

Existing valve stem seal press-fitting fixtures lack guiding and labor-saving structures, resulting in complex operation, easy misalignment or shearing, and different machine models require different fixtures, increasing workload and cost.

Method used

A valve stem seal press-fitting fixture including a press head and a bearing seat was designed. The press head is connected to the bearing seat through a detachable connector. The insert head and cavity structure ensure the coaxial installation of the valve stem seal, avoiding misalignment and shearing, and adapting to the needs of different models.

Benefits of technology

It enables simple and effective installation of valve stem seals, reduces operational complexity and workload, and can adapt to different models, thus reducing costs.

Abstract

The pressing head comprises a shaft seat and the pressing head, a connector of the pressing head is detachably connected with the shaft seat, the pressing head comprises a column body, the protruding connector is arranged on the front end face of the column body, a second cavity and a first cavity are sequentially formed in the rear end face of the column body from outside to inside, and the first cavity is communicated with the second cavity. The second cavity and the first cavity are coaxially arranged, the diameter of the second cavity is larger than that of the first cavity, an insertion head is arranged at the bottom of the first cavity and extends backwards, and the head of the insertion head penetrates out of the second cavity. The utility model has the beneficial effects that the pressure head, the valve oil seal and the shaft seat are assembled, then the insertion head is inserted into the valve guide pipe, and the shaft seat is pressed forcibly, so that the valve oil seal is sleeved on the valve guide pipe, the whole process is simple to operate, the workload is reduced, the valve oil seal can be used on other types of machines by replacing a front end pressure head, and the cost is saved.
