Description

Technical Field

[0001] The invention relates to the technical field of diesel engine cylinder head processing, in particular to an inclined hole processing device with controllable inclination and depth of a diesel engine cylinder head. Background Art

[0002] During the production process, diesel engine cylinder heads need to be drilled. Some cylinder heads need to be drilled with oblique holes to ensure that the cylinder heads can be installed later. When drilling oblique holes in the cylinder heads, the diesel engine cylinder heads are usually first fixed with a fixture. By adjusting the angle of the drilling device and the position during drilling, the inclination and depth of the processed oblique holes can be controlled. Although this method can complete the processing of oblique holes, when processing batches of diesel engine cylinder heads, the following steps need to be repeated manually: first, the diesel engine cylinder head is placed on the fixture and fixed with the fixture. After the oblique holes on the diesel engine cylinder heads are processed, the processed diesel engine cylinder heads are manually removed from the fixture. This method consumes a lot of manual labor and greatly reduces work efficiency, making it inconvenient for batch processing of diesel engine cylinder heads. To this end, we propose an oblique hole processing device for diesel engine cylinder heads with controllable inclination and depth. Summary of the Invention

The rotating shaft 1 and the rotating shaft 2 are connected for transmission through a sprocket transmission group 33. The sprocket transmission group 33 includes a sprocket and a chain, and the rotation of the contact gear 31 drives the driving gear 32 to rotate through the sprocket transmission group 33;

[0040] When the telescopic device 26 drives the cover plate 25 upward to a position that does not block the movable opening, the vertical rack 34 engages with the contact gear 31. It should be noted that when the cover plate 25 has not completely disengaged from the movable opening, the vertical rack 34 has not yet engaged with the contact gear 31, so that the pushing assembly can work.

[0041] Preferably, the pusher assembly of this embodiment includes a push plate (not shown in the figure) provided on the outside of the cylinder head holding bin 23 and capable of entering and exiting the movable port. The pusher plate is connected to the connecting plate 27, and the connecting plate 27 is connected to the U-shaped movable frame 28. The U-shaped movable frame 28 is slidably sleeved on the outer wall of the cylinder head holding bin 23. Both sides of the top of the U-shaped movable frame 28 are provided with teeth that engage with the driving gear 32. When the driving gear 32 rotates, the U-shaped movable frame 28 drives the pusher plate from one side of the movable port through the connecting plate 27 to push the cylinder head from the other side of the movable port onto the cylinder head supporting plate 11.

[0042] Preferably, the detection member of this embodiment includes a baffle 29 provided inside the cylinder head receiving chamber 23 and at the end of the cover plate 25 facing the regulating assembly. The baffle 29 is provided with a pressure sensor 30 for contacting the end of the positioning member facing the regulating assembly.

[0045] After the cylinder head is pushed onto the cylinder head supporting plate 11 by the pushing assembly, the elastic telescopic rod 19 is squeezed downward, so that the positioning piece is separated from the pressure sensor 30. When there is no cylinder head on the cylinder head supporting plate 11, the positioning piece of the cylinder head supporting plate 11 can contact the pressure sensor 30 as it is transported by the conveying device 1. After the pushing assembly pushes the cylinder head onto the cylinder head supporting plate 11, since the cylinder head has a certain gravity, it will press the cylinder head supporting plate 11, so that the cylinder head supporting plate 11 squeezes the elastic telescopic rod 19, and then the positioning piece is separated from the pressure sensor 30. After the pressure sensor 30 is separated and no contact signal is detected, the controller controls the conveying device 1 to continue conveying, and the telescopic device 2 26 drives the cover plate 25 to reset downward.

[0048] After the cylinder head is pushed onto the cylinder head supporting plate 11 by the pushing assembly, the limiting roller 17 moves downward with the cylinder head supporting plate 11, so that the limiting roller 17 corresponds to the bottom of the guide rail 35. Then, when the conveying device 1 conveys the cylinder head supporting assembly to the end of the conveying device 1, the limiting roller 17 moves along the guide rail 35, the gear column 16 corresponds to the upper part of the arc-shaped rack 36, and the driven gear 1 18 meshes with the driven gear 2 21.

When the conveying device 1 conveys the mounting plate 10, the limiting roller 17 slides in contact with the bottom of the guide rail 35, and the gear column 16 engages with the arc rack 36 when the mounting plate 10 moves to the end of the conveying device 1, driving the rotating shaft 15 to drive the cylinder head supporting plate 11 to flip toward the storage box, so that the cylinder head on the cylinder head supporting plate 11 falls into the storage box under its own gravity, and the driven gear 18 drives the driven gear 2 21 to drive the rotating shaft 2 20 to reel the pull rope 22 when the rotating shaft 15 rotates, so that the pull rope 22 pulls the movable retaining edge 13 to flip open, so that the movable retaining edge 13 does not block the cylinder head, so that the cylinder head falls into the storage box.

[0049] It should be noted that an elastic rubber pad-like protective structure is provided in the storage box to prevent the cylinder head from falling into the storage box and being damaged.
