[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] The utility model embodiment discloses a hole processing tool for a diesel engine cylinder head. Figure 1-4A hole processing tool for a diesel engine cylinder head, comprising a bottom plate 1, a support plate 2 is arranged at the upper end of the bottom plate 1, two first electric push rods 3 are arranged at the upper end of the support plate 2, the bottom ends of the two first electric push rods 3 are arranged with the same moving plate 4, a drilling mechanism 5 is arranged on the moving plate 4, which is used for drilling holes in the cylinder head, a U-shaped plate 6 is arranged on the front side of the upper end of the moving plate 4, a protective mechanism 7 is arranged on the inner side of the U-shaped plate 6, which is used to protect the drilling mechanism 5 when not in use, and a cleaning mechanism 8 is arranged on the upper end of the support plate 2, which can clean the drilling mechanism 5 in cooperation with the protective mechanism 7;

[0035] Reference Figure 3 The drilling mechanism 5 includes a motor 501 and a drill bit 502. The motor 501 is arranged at the upper end of the movable plate 4, and the drill bit 502 is rotatably arranged at the bottom end of the movable plate 4. The top end of the drill bit 502 is connected to the output shaft of the motor 501 for drilling the cylinder head.

[0036] By adopting the above technical solution, the motor 501 drives the drill bit 502 to rotate, and then the first electric push rod 3 drives the drill bit 502 to move, so that the drill bit 502 can perform drilling processing on the cylinder head when it contacts the cylinder head.

[0037] Reference Figure 3 The protective mechanism 7 includes a bidirectional screw 701, two threaded sleeves 702, two sliders 703, two connecting rods 704 and a protective sleeve 705. The bidirectional screw 701 is rotatably arranged on the inner side of the U-shaped plate 6. The two threaded sleeves 702 are both threadedly arranged on the bidirectional screw 701. The two sliders 703 are respectively arranged on one side of the corresponding threaded sleeves 702. The two connecting rods 704 are respectively hinged at the bottom ends of the corresponding sliders 703. The protective sleeve 705 is arranged on the outer side of the drill bit 502, and the bottom end of the connecting rod 704 is hinged to the outer side of the protective sleeve 705, which is used to protect the drill bit 502 when not in use; a plurality of guide openings 13 are opened on the movable plate 4, and a guide rod 14 is arranged in the guide opening 13. The slider 703 is located in the guide opening 13 and is slidably connected with the guide rod 14.

[0038] By adopting the above technical solution, after the drilling process is completed, the staff can rotate the bidirectional screw 701. The rotation of the bidirectional screw 701 drives the two threaded sleeves 702 to approach each other. The movement of the threaded sleeve 702 drives the slider 703 to slide on the guide rod 14. The movement of the slider 703 drives the connecting rod 704 to rotate. The rotation of the connecting rod 704 drives the protective sleeve 705 to move downward, so that the bottom end of the drill bit 502 can be located on the inner side of the protective sleeve 705, so that the bottom end of the drill bit 502 is not easily affected by external collisions, thereby greatly improving the protection of the drill bit 502.

[0039] Reference Figure 2 and Figure 4The cleaning mechanism 8 includes a fan 801 and an air blowing pipe 802. The fan 801 is arranged at the upper end of the support plate 2, and the air blowing pipe 802 is arranged at the air outlet end of the fan 801. The end of the air blowing pipe 802 away from the fan 801 is connected to the protective sleeve 705; a cavity 11 is opened inside the protective sleeve 705, and the end of the air blowing pipe 802 away from the fan 801 penetrates into the cavity 11, and a plurality of air blowing holes 12 connected to the cavity 11 are opened on the inner side of the protective sleeve 705.

[0040] By adopting the above technical solution, the fan 801 works while the protective sleeve 705 moves, and air can be blown into the cavity 11 through the air pipe 802. Finally, the air is sprayed out through the air hole 12 to clean the debris on the surface of the drill bit 502. Therefore, when the drill bit 502 is used subsequently, there is no need for the staff to manually clean its surface.

[0041] Reference Figure 1 and Figure 2 A second electric push rod 9 is provided at the lower ends of the left and right sides of the support plate 2, and a clamping plate 10 is provided at one end of the second electric push rod 9 for clamping and fixing the cylinder head.

[0042] By adopting the above technical solution, the cylinder head is placed on the upper end of the base plate 1 when drilling, and then the second electric push rod 9 works to push the clamping plate 10 to move. The cylinder head can be clamped and fixed by the two clamping plates 10, so that the cylinder head is not easy to shake during drilling.

[0043] Working principle: When the utility model is in use, the electrical components appearing in the present application are all connected to an external power supply and a control switch. When drilling a hole in the cylinder head, it is placed on the upper end of the bottom plate 1, and then the second electric push rod 9 works to push the clamping plate 10 to move. The cylinder head can be clamped and fixed by the two clamping plates 10, and then the first electric push rod 3 drives the moving plate 4 to move downward. At this time, the motor 501 works to drive the drill bit 502 to rotate. When the drill bit 502 contacts the cylinder head, the cylinder head can be drilled. After the drilling process is completed, the staff can rotate the bidirectional screw 701. The rotation of the bidirectional screw 701 drives the two threaded sleeves 702 to approach each other, and the threaded sleeves 702 move with The movable slider 703 slides on the guide rod 14, and the movement of the slider 703 drives the connecting rod 704 to rotate, and the rotation of the connecting rod 704 drives the protective sleeve 705 to move downward, so that the bottom end of the drill bit 502 can be located on the inner side of the protective sleeve 705, so that the bottom end of the drill bit 502 will not be collided when the cylinder head is taken, which greatly improves the protection of the drill bit 502, and while the protective sleeve 705 moves, the fan 801 works, and air can be blown into the cavity 11 through the air pipe 802, and finally, the debris on the surface of the drill bit 502 can be cleaned by spraying through the air hole 12, so that when the drill bit 502 is used subsequently, there is no need for the staff to manually clean its surface.

[0044] When the utility model is in use, the bottom end of the drill bit 502 can be safely protected after drilling is completed, so that the bottom end of the drill bit 502 is not easily impacted by the outside world, thereby greatly improving the protection of the drill bit 502, and the debris on the surface of the drill bit 502 can be cleaned without the need for staff to manually clean its surface.
