Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0030] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] Please see Figures 1 to 5 The automatic tapping machine for die castings according to one embodiment of the present invention includes a machine body 10, a tapping assembly 20 installed in the middle of the machine body 10, a feeding assembly 30 installed on one side of the tapping assembly 20, and a discharging assembly 40 installed on the other side of the tapping assembly 20.

[0033] The top surface of the machine body 10 is provided with a processing table 11, and the top surface of the processing table 11 is inclined. The loading assembly 30 is located on the upper side of the processing table 11, and the unloading assembly 40 is located on the lower side of the processing table 11.

[0034] The tapping assembly 20 includes a turntable 21 rotatably mounted on the top surface of the machining table 11, a drive motor (not shown) installed inside the machining table 11, a guard plate 22 installed on one side of the turntable 21, a clamping pin 23 slidably mounted on the side of the guard plate 22 away from the turntable 21, a push-pull cylinder 24 connected to the clamping pin 23, a support column 25 installed on one side of the machining table 11, a spindle 26 installed on the top of the support column 25, and a tap 27 coaxially mounted on the bottom of the spindle 26; the drive motor is connected to the turntable 21 to drive the turntable 21 to rotate.

[0035] Specifically, a plurality of receiving openings 210 are evenly spaced on the outer shaft surface of the turntable 21. The receiving openings 210 are used to accommodate the die-cast part 50. The height of the die-cast part 50 is greater than the thickness of the turntable 21. The tap 27 is correspondingly positioned above the receiving openings 210.

[0036] like Figure 2 As shown, the clamping pin 23 is slidably connected to the machining table 11 via the guide rail pair 230, and the push-pull cylinder 24 is used to drive the clamping pin 23 to move closer to or away from the turntable 21; the clamping pin 23 is arranged along the radial direction of the turntable 21. The clamping pin 23 is used to pass through the guard plate 22 and clamp the die-cast part 50 to facilitate tapping the inner wall of the die-cast part 50 by the tap 27, thereby improving the stability of the tapping process.

[0037] In this embodiment, as Figure 5 As shown, the guard plate 22 is arc-shaped, allowing it to fit snugly against one side of the turntable 21, effectively preventing the die-cast part 50 from detaching from the receiving opening 210. A through hole 220 is provided in the middle of the guard plate 22 for the insertion of the clamping pin 23.

[0038] The feeding assembly 30 includes a vibratory plate 31 located on one side above the processing table 11, and a direct vibratory feeder 32 connected to the outlet of the vibratory plate 31; the outlet end of the direct vibratory feeder 32 faces the turntable 21; the die-cast part 50 is fed into the receiving port 210 of the turntable 21 through the vibratory plate 31 and the direct vibratory feeder 32.

[0039] In this embodiment, the direct vibration feeder 32 is arranged along the radial direction of the turntable 21.

[0040] The unloading assembly 40 includes an unloading track 41 located on one side of the turntable 21, a rotating shaft 42 rotatably mounted on one side of the unloading track 41, a toggle motor (not shown) installed inside the processing table 11, and an unloading deflector 43 coaxially mounted on the top of the rotating shaft 42. The unloading deflector 43 is located above the turntable 21 and is used to abut the portion of the die-cast part 50 that extends beyond the top surface of the turntable 21. The toggle motor drives the rotating shaft 42 to rotate. In actual operation, the rotating shaft 42 drives the unloading deflector 43 to rotate, which can deflect the die-cast part 50 out of the receiving port 210 and drop it into the unloading track 41.

[0041] In this embodiment, the direct vibration feeder 32 is located on one side of the guard plate 22, and the unloading track 41 is located on the other side of the guard plate 22. Compared with traditional die-casting tapping machines, this utility model integrates the feeding assembly 30 and the unloading assembly 40 on opposite sides of the guard plate 22. After a single tapping operation, it can seamlessly connect to the unloading station and peel off the die-cast part 50 through the unloading baffle 43 without the need to switch tooling, effectively reducing non-machining waiting time and greatly improving the overall processing efficiency.

[0042] In this embodiment, the rotation direction of the rotating shaft 42 is the same as that of the turntable 21.

[0043] In this embodiment, one end of the feeding track 41 faces the turntable 21, and the other end of the feeding track 41 faces the collection basket (not shown). The height of the feeding track 41 gradually decreases from the turntable 21 toward the collection basket, so that the die-cast part 50 can automatically slide down the feeding track 41 into the collection basket.

[0044] The aforementioned automatic tapping machine for die castings has a simple structure and is easy to use. The feeding component 30 and the unloading component 40 are integrated on opposite sides of the guard plate 22. After a single tapping operation, it can seamlessly connect to the unloading station and peel off the die casting 50 through the unloading plate 43 without the need to switch tooling. This effectively reduces non-machining waiting time and greatly improves the overall processing efficiency.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
