Description

Technical Field

[0001] The utility model belongs to the technical field of press-fitting machines, and in particular relates to a cylinder head accessory press-fitting machine. Background Art

[0002] The traditional cylinder head cover oil seal installation method is to make a round rod of appropriate size according to the size of the cylinder head cover mounting hole. During assembly, the oil seal is placed into the mounting hole of the cylinder head cover, and then the round rod is tapped with a rubber hammer to make the oil seal fit into place. The press-fitting machine on the market uses a cylinder and a pressing head to press the oil seal into the mounting hole of the cylinder head cover.

[0003] However, there are multiple mounting holes on the cylinder head cover that all need to be press-fitted with oil seals. In addition, in order to prevent deviation during pressing, the cylinder head cover needs to be accurately positioned and locked before pressing. This makes the positioning process of the cylinder head cover under the pressure head more cumbersome. After the cylinder head cover is pressed, there is a cumbersome operation of canceling the lock, removing it, and re-clamping the next cylinder head cover. In addition, the annular oil seal is easily deformed during the pressing process. The deformed oil seal and the mounting hole of the cylinder head cover will affect the sealing due to insufficient assembly accuracy. Utility Model Content

[0014] Through the provided cylinder head anti-deviation mechanism, the press-fitting positioning column adapted to the oil seal mounting hole can play an anti-deviation positioning role for the cylinder head as a whole, and the cylinder head can be easily removed upwards after the press-fitting work is completed because the cylinder head is not restricted in the axial direction of the press-fitting positioning column. In addition, the flexible control of the height of a row of press-fitting positioning columns can adapt to the positioning of the oil seal mounting holes of cylinder heads of different heights and adjust them according to the press-fitting height of the oil seal in the mounting hole.

[0015] By setting up a centralized anti-bias pressing mechanism, when pressing is in progress, the oil seal sleeve column fills the oil seal ring center hole to prevent it from being deformed during the pressing process and ensure the pressing sealing accuracy.

[0026] This solution has the following working process: before use, the oil seal mounting hole of the cylinder head is aligned with the press-fitting positioning column 2 extending from the press-fitting workbench 1 and placed, so that the press-fitting positioning column 2 adapted to the oil seal mounting hole can play an anti-deviating positioning role for the cylinder head as a whole, and the cylinder head is not restricted in the axial direction of the press-fitting positioning column 2, which can facilitate its upward removal after the press-fitting work is completed.
