Embodiment Construction
[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work, any modifications, equivalent replacements, improvements, etc., shall be included in the protection scope of the present invention Inside.
[0015] like figure 1 As shown, the oil seal press-fitting device of the present invention includes a pressure sleeve 2, a clamping shaft 3 is arranged in the middle of the pressure sleeve 2, and a pressure sleeve inner hole 4 is provided in the middle of the clamping shaft 3. The upper end of the hole 4 is provided with a ventilation hole 5, the lower end of the ventilation hole 5 commun...

The invention discloses an oil seal press fitting device. The oil seal press fitting device comprises a pressing sleeve, an installing and clamping shaft is arranged in the middle, a pressing sleeve inner hole is formed in the middle of the installing and clamping shaft, and an air vent is formed in the upper end of the pressing sleeve inner hole; an installing and clamping groove is formed between the installing and clamping shaft and the pressing sleeve and used for installing an oil seal in a clamping mode, and the oil seal is installed in the installing and clamping groove in a clamping mode; a base is arranged at the lower end of the pressing sleeve, a positioning boss is arranged in the middle of the base, a guide pillar is arranged in the middle of the positioning boss, and the base is installed on a working table in a clamping mode and fixedly connected through bolts. The oil seal press fitting device solves the problem that according to an original pressing machine tool, a shell oil seal installing hole is not coaxial with the pressing sleeve, and therefore the pressing sleeve is not guided to cause oil leakage of the oil seal. The planeness of the oil seal after press fitting can be limited well through dimensional tolerance between the base, the pressing sleeve and a shell, the coaxiality of oil seal press fitting can be ensured through control over the axial gap between the base and the pressing sleeve, and the problem of oil leakage of the oil seal is effectively solved.
Description
[0001] technical field [0002] The invention relates to the technical field of hydraulic press assembly, in particular to an oil seal press assembly device. Background technique [0003] At present, in the field of oil press assembly technology, especially in the aspect of oil seal pressing, a large part of oil seal pressing devices are not designed properly, resulting in insufficient pressing accuracy, which cannot meet the requirements of assembly quality, specifically in the installation of oil seal press sleeves and oil seals The poor coaxiality of the hole and the tilting of the oil seal press, etc. lead to defects such as oil leakage at the oil seal. Contents of the invention [0004] The purpose of the present invention is to provide an oil seal press-fitting device for the above-mentioned shortcomings and deficiencies of the prior art, which can effectively solve the problem that the oil seal press sleeve is coaxial with the oil seal installation hole when the oi...
