Embodiment Construction

[0015] An adaptive multi-head press-fitting mechanism as shown in Figures 1 to 3, including: a driving mechanism 100, a pneumatic swing table limit mechanism 200, a pressure self-adjusting mechanism 300, and a press-fitting system 400; pressure head I2, pressure head II3 There are 4 spring plungers on the top for positioning and holding materials. The four pressure heads I2 and II3 of the press-fitting system are respectively installed in the four pistons 5, supported by the O-shaped sealing ring 4, and the position is limited by the positioning pin 6 to form a floating connection. Four pistons 5 are packed into an oil cylinder block 7, and the oil cylinder block 7 and the pressure head body 10 are fixed by bolt connection. The cavity formed in the middle of the oil cylinder block 7 and the pressure head body 10 is filled with thick pressure oil, which is closed by steel balls and screws. The indenter body 10 is fixed on the support plate 16 through the oil-free bearing 14 an...

Abstract

The invention discloses a self-adaptive multi-head press fit mechanism. The invention is characterized in that the press fit system comprises 4 pressing heads which are respectively arranged in 4 pistons, are supported by an O-shaped sealing ring and are positioned by a positioning pin so as to form a floating connection. The 4 pistons are arranged in an oil cylinder body; the oil cylinder body and a pressing head body are fixedly connected through a bolt. Viscous pressure oil is fully injected in a cavity formed between the oil cylinder body and the pressing head body; the cavity is sealed by steel balls and screws. The pressing head body is fixed on a bracket through an oil-free bearing and a flange and can be freely rotated. The pressing head body is fixed with pressing plates and gears; the pressing plates are arranged according to required phase positions; the initial phase position is determined by a gear pair; a mating gear is arranged on a pneumatic swing platform; the positioning pin is arranged on the mating gear; the gear pair is driven by the pneumatic swing platform to rotate; the shape of the pressing plate can control the required angles and can automatically lock the phase position. The pneumatic swing platform is arranged on the bracket which is pushed by the oil cylinder to advance and achieves the press fit by the guidance of a guide rod.

Description

technical field [0001] The invention relates to an adaptive multi-head press-fitting mechanism, which is used for assembling cylinder heads and seat rings (valve seats) in mass production of engines. Background technique [0002] At present, whether it is a gasoline engine or a diesel engine, there are still many manufacturers using a single-axis assembly method in the assembly of the seat ring. This method has low production efficiency and requires multi-station press assembly. The degree of automation is low and the design is difficult. And fixtures require high precision and occupy a large area. Contents of the invention [0003] In order to overcome the shortcomings of the existing assembly methods, the present invention provides a multi-head press-fit mechanism, which adopts single-axis multi-head press-fit, and uses a pneumatic swing table to drive gear pairs to complete different phase rotations, and utilizes the principle of liquid force transmission to Compensate...
