DETAILED DESCRIPTION

[0028] 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.

[0029] like Figures 1 to 7 As shown, the utility model provides an internal combustion engine body oil channel hole processing device, including a drilling table 1, a lifting component is installed on the drilling table 1, and a motor 3 is connected to the lifting component. The motor 3 drives the installation mechanism 4 to rotate.

[0030] The lifting assembly includes a bracket 2 located on the upper side of the drilling table 1. The bracket 2 keeps the drill bit 5 away from the drilling table 1. A U-shaped plate 21 is arranged on the upper end of the bracket 2. Limit rods 23 are symmetrically arranged on the U-shaped plate 21. The limit rods 23 are slidably connected to the front plate 24. The motor 3 is fixed on one side of the front plate 24. When drilling, the height of the drill bit 5 is lowered by sliding the front plate 24 on the limit rod 23 to meet the drilling requirements.

[0031] In order to realize automatic drilling, a screw rod 22 is rotatably set on the U-shaped plate 21 between the two limit rods 23. The screw rod 22 is threadedly connected to the front plate 24. The upper end of the screw rod 22 is connected to the output shaft of the driving motor. The screw rod 22 is driven by the driving motor to rotate. The front plate 24 is restricted by the limit rod 23 and reciprocates on the screw rod 22 to realize lifting.

[0032] The drill bit 5 is fixed on the lower side of the mounting mechanism 4, wherein: the mounting mechanism 4 includes a mounting sleeve 41 connected to the output shaft of the motor 3, a connecting head 47 is provided at the upper end of the drill bit 5, and the connecting head 47 is threadedly connected to the mounting head 51 provided at the upper end of the drill bit 5 for easy disassembly, and the connecting head 47 is fixed in the mounting sleeve 41 by plugging.

[0033] Specifically, cavities 45 are opened on both sides of the installation sleeve 41, and a mounting plate 46 is slidably arranged in the cavity 45. One end of the mounting plate 46 passes through the side wall of the cavity 45 and extends to the outside. The end passing through the side wall of the cavity 45 is in the shape of a rod. When the mounting plate 46 is pushed, the mounting plate 46 slides into the installation sleeve 41, so that the other end of the mounting plate 46 is plugged into and matched with the sockets 48 opened on both sides of the connector 47 to fix the connector 47.

[0034] A symmetrical spring 451 is arranged in the cavity 45, one end of the spring 451 is connected to one side of the mounting plate 46, and the mounting plate 46 slides into the mounting sleeve 41, and the spring 451 is in a stretched state. Therefore, after the spring 451 loses its force, the mounting plate 46 can be assisted to quickly slide out of the mounting sleeve 41, thereby realizing the quick release of the drill bit 5.

[0035] Furthermore, a fixing member 42 is provided on the outer side of the mounting sleeve 41, and a slide groove 421 is provided on both sides of the fixing member 42. An L-shaped rod 43 is slidably provided in the slide groove 421. The L-shaped rod 43 can push one end of the mounting plate 46 so that the mounting plate 46 can be stably inserted into the socket 48. A groove 431 adapted to one end of the mounting plate 46 is provided on the inner side of the L-shaped rod 43 to prevent the L-shaped rod 43 from being unstable when pushing the mounting plate 46.

[0036] Furthermore, an annular sleeve 44 is provided at the lower side of the L-shaped rod 43 . After the L-shaped rod 43 moves, it brings the annular sleeve 44 close to the drill bit 5 . The annular sleeve 44 performs secondary fixation on the drill bit 5 , thereby further improving the stability of the drill bit 5 .

[0037] Furthermore, a second slide groove 422 is opened on the other side of the fixing member 42, and an extension rod arranged on one side of the L-shaped rod 43 is slidably arranged in the second slide groove 422, and a second screw rod 423 is rotatably arranged in the second slide groove 422. The second screw rod 423 is a bidirectional screw rod, and the thread directions of the left and right sides thereof are opposite to each other with respect to the center, and the two extension rods are respectively threadedly connected to the two ends of the second screw rod 423. When the second screw rod 423 is rotated, the two L-shaped rods 43 can be moved toward or in the opposite directions, thereby realizing the rapid replacement of the drill bit 5.

[0038] In order to enable the operator to understand the exact position of the drill bit 5 entering the mounting sleeve 41, a fixing plate 411 is set at the upper end of the mounting sleeve 41, and a positioning rod 412 is set at the center of the fixing plate 411. The lower end of the positioning rod 412 passes through the fixing plate 411 and extends to the lower end. When the drill bit 5 enters the mounting sleeve 41, if the positioning rod 412 is plugged into the positioning hole 49 opened on the upper side of the connecting head 47, the position of the drill bit 5 can be fixed by the mounting plate 46.

[0039] The working principle of an internal combustion engine body oil channel hole processing device: After the connecting head 47 is threadedly connected with the mounting head 51, the connecting head 47 is inserted into the mounting sleeve 41. After the positioning hole 49 is inserted into the positioning rod 412, the position of the drill bit 5 is determined. At this time, the screw rod 423 is rotated to make the L-shaped rod 43 slide to push one end of the mounting plate 46, so that the other end of the mounting plate 46 is inserted into the sockets 48 on both sides of the connecting head 47 to fix the drill bit 5. At the same time, the L-shaped rod 43 with the annular sleeve 44 performs secondary fixation on the upper end of the drill bit 5 to ensure the stability of the drill bit 5.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
