Problems solved by technology
Such a problem is that when the assembly surface of the PCV hard tube and the valve cover is not well bonded, the gas will leak from the installation joint surface of the valve cover; There is a leak
[0003] In the traditional installation method, the outer circle of the PCV hard pipe is assembled and frozen, and then the outer circle of the PCV hard pipe is assembled with glue, and the valve chamber cover and the chamfer of the PCV hard pipe are used as guides to knock the PCV hard pipe into the hole with a hammer. It is extremely inconvenient to install the PCV hard pipe in this way, resulting in high labor intensity for the operator, low assembly efficiency, and high production costs

The invention discloses a device and method for press-fitting an L-shaped PCV rigid tube. The labor intensity of workers is reduced, and the installation efficiency is improved. The device for press-fitting the L-shaped PCV rigid tube comprises a baseboard, positioning pins, press plate assemblies, a tube-fitting guiding column, a tube-fitting accessory and an angle guiding device; the positioningpins are used for positioning an engine valve-chamber cover; the press plate assemblies are used for pressing the engine valve-chamber cover; the tube-fitting guiding column is used for guiding downward press-fitting of the L-shaped PCV rigid tube; a groove opening is formed in one side of the tube-fitting accessory, and is used for matching the L-shaped PCV rigid tube; and the angle guiding device comprises a side top limiting base and a side top limiting assembly, a lower wall of the side top limiting base is fixed onto the baseboard, upper walls of the side top limiting base comprise a left guiding wall and a right guiding wall, a threaded hole is formed in a vertical wall of the side top limiting base, the left guiding wall and the right guiding wall are used for limiting the angle ofthe PCV rigid tube, the side top limiting assembly comprises a screw, the screw matches the threaded hole, and a rubber plug is arranged at one end of the screw, and is used for matching a side holeof the L-shaped PCV rigid tube to limit an axial position of the PCV rigid tube and to form sealing.
Description
technical field [0001] The invention relates to the technical field, in particular to a device and method for press-fitting an L-shaped PCV hard pipe. Background technique [0002] At present, when enterprises install the engine assembly, they directly press-fit the PCV hard pipe on the valve chamber cover. Such a problem is that when the assembly surface of the PCV hard tube and the valve cover is not well bonded, the gas will leak from the installation joint surface of the valve cover; There is a leak. [0003] In the traditional installation method, the outer circle of the PCV hard pipe is assembled and frozen, and then the outer circle of the PCV hard pipe is assembled with glue, and the valve chamber cover and the chamfer of the PCV hard pipe are used as guides to knock the PCV hard pipe into the hole with a hammer. It is extremely inconvenient to install PCV hard pipes in this way, resulting in high labor intensity for operators, low assembly efficiency, and high pro...
