Embodiment Construction
[0012] Hereinafter, the present invention will be further explained based on the drawings.
[0013] The connecting rod bearing bush press-fitting sheath structure shown in the figure is based on the sliding mold base 1 as the frame, and the slide plate 1.1 located at the upper end of the sliding mold base 1 is fixedly connected with the dynamic pressure head 2 and the dynamic pressure head 2 by screws 2.2. The outer wall is sheathed with a sheath 2.4 with clearance fit, and a compression spring 2.3 is sheathed between the outer wall of the sheath 2.4 and the fixed end of the dynamic pressure head 2 to form an axial telescopic structure. The axial sliding of the sheath 2.4 relative to the dynamic pressure head 2 is limited by the screw 2.1 Bit. In the present invention, the inner diameter of the sheath 2.4 is equivalent to the inner diameter of the base 6, and the inner diameter is in clearance fit with the outer diameter of the bearing bush 7. The base 6 is installed on the bottom...

The invention discloses a press mounting protecting and leading structure for a connecting rod bearing, which comprises a movable scaffolding device, a dynamic head, a sliding core and a base. The protecting and leading structure is characterized in that the dynamic head is fixedly connected in the middle of the bottom surface of the sliding plate positioned at the upper end of the movable scaffolding device through screws, and an outer expansible protecting and leading structure in the axial direction consists of a pressure spring and a sheathing screw is arranged on the outer wall of the dynamic head. The base is mounted on the bottom plate at the lower end positioned in the movable scaffolding device, the inner hole of the base and the dynamic head are coaxial, the inner hole of the base and the sliding core are in clearance fit, the expansible structure in the axial direction consists of the pressure spring is mounted in the inner hole of the sliding core in the axial direction downwards, and the top end of the sliding core and the inner hole of a bearing bush are in clearance fit to form an inner-wall protecting and leading structure. A positioning step of a positioning pin and the base have equal heights, and the center distance between the positioning pin and the base is equal to that between two end holes of a connecting rod. The press mounting of the bearing bush is performed under the condition that the connecting rod is fully positioned at two end holes and under the protection of the protecting and leading structure, the bearing bush is not deformed during the process of press mounting, the quality of products is stable, and the production efficiency is high.
Description
Technical field [0001] The invention relates to a molding device, in particular to a molding device with a protective guide structure. Background technique [0002] The connecting rod is the key part of the engine to transmit power, and its quality directly affects the quality of the engine. The mating end of the connecting rod and the crankshaft is a pair of friction pairs, and non-ferrous metal bearing bushes are arranged in the connecting rod hole to reduce friction. The fit between the bearing bush and the connecting rod is an interference fit, and the prior art adopts a pressure machine to quickly realize batch installation. However, the thin-walled bearing bush has poor rigidity and is easy to deform during the press-fitting process, which affects the matching quality of the bearing bush and the connecting rod hole. Summary of the invention [0003] The present invention mainly aims at the shortcomings of the prior art, and proposes a simple structure of the connecting rod...
