Description

Technical Field

[0001] This utility model relates to the field of engine cylinder liner press-fitting technology, specifically to a positioning and clamping device for engine cylinder block and cylinder liner press-fitting. Background Technology

[0002] An engine is a power component that generates power through its thermal operation. During engine manufacturing, cylinder liners are frequently press-fitted onto the engine. After press-fitting, the pistons can operate smoothly. Because engines are multi-cylinder structures, such as three-cylinder or four-cylinder engines, current engine manufacturing processes require pressing each cylinder liner onto the engine block individually. This is typically done by pressing with liquid nitrogen cooling. After pressing, the cylinder liners are allowed to return to room temperature to maintain an interference fit.

[0003] For example, Chinese patent CN217943219U discloses an engine cylinder liner press-fitting device. This component includes a press-fitting base, a press-fitting frame connected to the top of the press-fitting base, slide blocks fixedly connected to the left and right sides of the top of the press-fitting frame, and a cylinder block positioning mechanism connected between the slide blocks. The cylinder block positioning mechanism includes platforms spaced apart front and rear, with the two ends of the platforms connected by adjusting connectors. Each platform is equipped with a pressure bar locking component, each including a sliding column connected to the left and right sides of the top of the platform, with a pressure bar connecting between the sliding columns for pressing and positioning the engine cylinder block. A hydraulic component cooperating with the cylinder block positioning mechanism is connected to the top of the press-fitting base. This device design securely presses and locks multiple cylinder liners on the engine cylinder block structure during the press-fitting process, facilitating both secure pressing and easy cylinder block pressing.

[0004] However, in actual use, the above solution cannot be used to position and press the V-type engine cylinder block and cylinder liner due to the angle of the hydraulic cylinder telescopic shaft when it is pressed down. This results in the press-fitting device being unable to position and press different engine cylinder blocks and cylinder liners. To solve the above problem, we propose a positioning and pressing device for press-fitting engine cylinder blocks and cylinder liners. Utility Model Content
