The clamping part is used to hold workpieces of different sizes, and the adjusting part is used to adjust different processing positions. The adjusting part includes a fixed frame, and a sliding plate is slidably connected to one side of the fixed frame. The advantages of this invention are: the adjusting part and the clamping part are provided. The clamping part clamps and fixes aluminum alloy castings of different sizes, preventing the castings from shaking or shifting during processing. The adjusting part adjusts the position of the mounting part according to the different sizes of the aluminum alloy castings and the different processing positions.

[0003] In the aforementioned prior art, when drilling and tapping aluminum alloy castings, the drilling bit and the tapping bit are at the same height, and when drilling or tapping the casting, the drilling bit and the tapping bit are not likely to come into contact with the casting, which can easily lead to damage to other areas of the casting.

[0004] Therefore, a drilling and tapping machine for aluminum alloy castings is proposed to solve the problems mentioned above. Utility Model Content

The moving end at the bottom of the second linear actuator is fixedly connected to the conversion mechanism; The conversion mechanism includes a drive disk, the movable end at the bottom of the second linear driver is fixedly connected to the drive disk, a drive motor is fixedly connected to the center of the drive disk, and the output shaft on the drive motor is fixedly connected to the center of the connecting disk. The bottom left and right ends of the connecting plate are respectively equipped with processing components.

[0007] Preferably, a gear ring is fixedly connected to the bottom of the drive disk, the gear ring meshes with the first gear and the second gear, the second gear meshes with the third gear, and the first gear, the second gear, and the third gear are rotatably connected to the top of the connecting disk.

[0008] Preferably, the first gear and the third gear are each connected to a set of processing components.

[0009] Preferably, the processing component connected to the first gear includes a screw, the top of which is fixedly connected to the center of the first gear, the screw is rotatably connected to the connecting disc, the screw is internally threaded to a threaded sleeve, the sidewall of the threaded sleeve is slidably connected to a guide rod, the top of the guide rod is fixedly connected to the connecting disc, a grinding motor is fixedly connected to the bottom of the threaded sleeve, and a drilling bit is fixedly connected to the output shaft of the grinding motor.

[0013] Compared with the prior art, this utility model provides an integrated drilling and tapping machine for aluminum alloy castings, which has the following beneficial effects: 1. While the connecting disc rotates, it drives the first and second gears at the upper end to mesh with the gear ring. The second gear meshes and drives the third gear to rotate. The first and third gears rotate in opposite directions. The first and third gears also drive the screw to rotate. The screw drives the threaded sleeves to move. One set of threaded sleeves connected to the drill bit moves upward, and one set of threaded sleeves connected to the tapping drill bit moves downward, making the bottom of the drilling drill bit higher than the bottom of the tapping drill bit, thus preventing the drilling drill bit from contacting other parts of the casting when the tapping drill bit contacts the casting.

[0014] 2. When the threaded sleeve moves upward, it squeezes the telescopic air bladder, causing the air inside the bladder to be discharged outward and enter the telescopic tube. The telescopic tube then transmits the air to the nozzle, which sprays the air onto the surface of the drill bit, causing any remaining impurities on the surface of the drill bit to fall off.

[0020] At this time, the side wall of the frame 1 is bolted with a first linear actuator 4, the moving end of the first linear actuator 4 is fixedly connected to a second linear actuator 5, and the first linear actuator 4 is used to adjust the position of the conversion mechanism 6XZ axis for casting processing.

[0021] The movable end at the bottom of the second linear actuator 5 is fixedly connected to the conversion mechanism 6; The conversion mechanism 6 includes a drive disk 61, the moving end of the bottom of the second linear driver 5 is fixedly connected to the drive disk 61, a drive motor 62 is fixedly connected to the center of the drive disk 61, and the output shaft 63 on the drive motor 62 is fixedly connected to the center of the connecting disk 64. Processing components 65 are respectively provided at the left and right ends of the bottom of the connecting plate 64; At this time, a gear ring 66 is fixedly connected to the bottom of the drive disk 61. The gear ring 66 meshes with the first gear 67 and the second gear 68. The second gear 68 meshes with the third gear 69. The first gear 67, the second gear 68, and the third gear 69 are rotatably connected to the top of the connecting disk 64. The first gear 67 and the third gear 69 are respectively connected to a set of machining components 65; The processing component 65 connected to the first gear 67 includes a screw 651. The top of the screw 651 is fixedly connected to the center of the first gear 67. The screw 651 is rotatably connected to the connecting plate 64. The screw 651 is internally threadedly connected to the threaded sleeve 652. The side wall of the threaded sleeve 652 is slidably connected to the guide rod 653. The top of the guide rod 653 is fixedly connected to the connecting plate 64. A grinding motor 654 is fixedly connected to the bottom of the threaded sleeve 652.

[0022] Among them, a drilling bit is fixedly connected to the output shaft of the grinding motor 654, a telescopic airbag 655 is connected to the side wall of the threaded sleeve 652, the top of the telescopic airbag 655 is connected to the bottom of the connecting plate 64, the bottom of the telescopic airbag 655 is fixedly connected to the telescopic tube 656, the lower end of the telescopic tube 656 is connected to the nozzle 657, and the lower air outlet of the nozzle 657 is located at the upper end of the drilling bit on the grinding motor 654; A tapping drill bit is connected to the output shaft of the grinding motor 654 on the machining assembly 65 connected to the third gear 69.

[0023] The working principle of the above embodiments is as follows: When in use, the aluminum alloy casting to be processed is placed on the fixture 3, and then the aluminum alloy casting is clamped and fixed by the fixture 3. Then, when drilling holes in the aluminum alloy casting, the X and Z axis positions of the conversion mechanism 6 are adjusted by the first linear driver 4 and the second linear driver 5, so that the drilling drill bit and tapping drill bit connected to the two sets of grinding motors 654 are located at the upper end of the casting. When drilling is required, a set of grinding motors 654 is controlled to drive the drilling bit to rotate and drill holes in the casting. After drilling is completed, the electric push rod 2 is controlled to drive the clamp 3 and the casting to move downward. Then, the drive motor 62 is controlled to drive the connecting plate 64 to rotate. The connecting plate 64 drives the two sets of conversion mechanisms 6 to rotate and change positions. While the connecting plate 64 is rotating, it drives the first gear 67 and the second gear 68 at the upper end to mesh with the gear ring 66.

The first gear 67 and the third gear 69 also drive the screw 651 to rotate at the same time. The screw 651 drives the threaded sleeve 652 to move. A set of threaded sleeves 652 connected to the drilling bit moves upward, and a set of threaded sleeves 652 connected to the tapping bit moves downward, so that the bottom height of the drilling bit is higher than that of the tapping bit, thus preventing the drilling bit from contacting other parts of the casting when the tapping bit contacts the casting. When the threaded sleeve 652 moves upward, it squeezes the telescopic air bladder 655, causing the air inside the telescopic air bladder 655 to be discharged outward and enter the telescopic tube 656. The telescopic tube 656 then transmits the air to the nozzle 657, which sprays the air onto the surface of the drilling bit, causing any remaining impurities on the surface of the drilling bit to fall off.
