DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to further explain the technical solution of the utility model, the following is elaborated in detail through specific embodiments.

[0022] As Figure 1As shown in the figure, the present utility model provides a rotary hardware punching device, which includes a base 1, a discharge frame 2 fixedly installed on the side surface of the base 1. The discharge frame 2 is used for discharging the processed hardware workpieces, a high-speed motor 3 arranged above the base 1. The base 1 is connected to the high-speed motor 3 through a three-axis adjustment frame arranged on the top. A drill foot needle 18 is fixedly installed on the bottom output shaft of the high-speed motor 3. The drill foot needle 18 is used to extrude the rivets in the hardware workpiece, so as to realize the deformation of the rivets and the pressing and fixing of the two workpieces.

[0023] In this embodiment, the discharge frame 2 is of a U-shaped structure, and the end of the discharge frame 2 away from the base 1 extends obliquely downward, which is convenient for the processed hardware workpieces to slide out of the discharge frame 2.

[0024] In this embodiment, the three-axis adjustment frame includes a sliding groove 8 opened at the rear end of the top of the base 1, a first motor 11 locked and fixed to the rear end face of the base 1, a first moving frame 9 slidably installed in the sliding groove 8. The first moving frame 9 can horizontally move back and forth along the inner side of the sliding groove 8, a first lead screw 10 rotatably installed in the sliding groove 8, a second motor 12 locked and fixed to the side surface of the first moving frame 9, a second lead screw 13 rotatably installed inside the first moving frame 9, a second moving frame 14 slidably installed inside the first moving frame 9. The second moving frame 14 can horizontally move left and right along the inner side of the first moving frame 9, a third motor 15 locked and fixed to the top of the second moving frame 14, a third lead screw 16 rotatably installed inside the second moving frame 14, a third moving frame 17 slidably installed inside the second moving frame 14. The third moving frame 17 can vertically move up and down along the inner side of the second moving frame 14, so as to adjust the height of the drill foot needle 18.

[0025] The front output shaft of the first motor 11 passes through the outer surface of the base 1 and is coaxially connected to the first lead screw 10. The first lead screw 10 is threadedly connected to the lower end of the first moving frame 9. The output shaft of the second motor 12 passes through the side surface of the first moving frame 9 and is coaxially fixedly connected to the second lead screw 13. The second lead screw 13 is threadedly connected to the rear end of the second moving frame 14. The bottom output shaft of the third motor 15 passes through the top end surface of the second moving frame 14 and is connected to the third lead screw 16. The third lead screw 16 is threadedly connected to the rear end of the third moving frame 17. The third moving frame 17 is connected to the rear end face of the high-speed motor 3, so as to realize driving the high-speed motor 3 and the drill foot needle 18 to move in the vertical direction through the third moving frame 17.

[0026] As Figure 1 and Figure 2As shown in the figure, in this embodiment, a circular feeding plate 4 is movably installed on the top end surface of the base 1. The circular feeding plate 4 can rotate horizontally on the top of the base 1 and is used to convey the hardware workpiece to the bottom of the drill foot needle 18. A driving motor 18 is locked and fixed inside the base 1, and an auxiliary pressing mechanism 6 and a discharging assembly 7 are arranged on the top of the base 1 and are both located outside the circular feeding plate 4. The auxiliary pressing mechanism 6 is used to provide auxiliary positioning for the workpiece, and the discharging assembly 7 is used to assist in discharging the workpiece;

[0027] A number of positioning frames 5 are annularly and equidistantly distributed on the top end surface of the circular feeding plate 4. The positioning frames 5 are used to provide positioning for the workpiece, improving the stability of the hardware workpiece during the punching process. Among them, the positioning frame 5 at the rear end is located below the drill foot needle 18;

[0028] A semi-gear 20 is fixedly sleeved on the output shaft of the driving motor 19. A transmission gear 21 is arranged on one side of the semi-gear 20 and meshes with it. The inner ring of the transmission gear 21 is fixedly equipped with a transmission rod 22 rotatably connected to the inside of the base 1. The transmission rod 22 passes through the top end surface of the base 1 and is connected to the middle of the bottom end surface of the circular feeding plate 4;

[0029] In this embodiment, the number of the positioning frames 5 provided on the circular feeding plate 4 is 4. Each time the semi-gear 20 at the bottom of the circular feeding plate 4 rotates one circle, it drives the transmission gear 21 to rotate horizontally by 90°, facilitating the stable conveyance of the hardware workpieces in different positioning frames 5 to the bottom of the drill foot needle 18 after the semi-gear 20 rotates one circle in cooperation with the transmission gear 21;

[0030] Specifically, during use, two hardware workpieces to be press-fitted and fixed are stacked, and the rivets on one hardware part are aligned with the through holes on the other hardware part. The hardware part with the rivets is arranged below, and the hardware part with the through holes is arranged above. Then the two hardware parts are placed flat in the positioning frames 5;

[0031] Then start the driving motor 19 to drive the semi-gear 20 to rotate. Each time the semi-gear 20 rotates one circle, it drives the transmission gear 21 to rotate by 90°. The transmission gear 21 drives the circular feeding plate 4 to rotate by 90° through the transmission rod 22. The circular feeding plate 4 drives the positioning frames 5 and the hardware workpieces to rotate until the positioning frame 5 with the hardware workpiece rotates to the bottom of the drill foot needle 18. At this time, the hardware workpiece is located below the drill foot needle 18 and awaits processing.

[0032] As Figure 3As shown in the figure, in this embodiment, the auxiliary pressing mechanism 6 includes a support frame 61 locked and fixed to the top of the base 1, and a lifting cylinder 62 fixedly installed on the side surface of the support frame 61. A U-shaped pressing frame 63 is installed on the bottom piston rod of the lifting cylinder 62. The lifting cylinder 62 is used to drive the U-shaped pressing frame 63 to move up and down. The U-shaped pressing frame 63 is located above the positioning frame 5 at the rear end. After the U-shaped pressing frame 63 moves downward, it is used to press the workpiece to be processed.

[0033] Among them, the support frame 61 is of an L-shaped structure, and the top end surface of the inner side of the support frame 61 and the bottom end surface of the lifting cylinder 62 are both higher than the top end surface of the circular feeding plate 4, reducing the friction between the circular feeding plate 4 and the support frame 61 and the lifting cylinder 62.

[0034] Specifically, during use, when the hardware workpiece is conveyed below the drill foot needle 18, the lifting cylinder 62 can be controlled to drive the U-shaped pressing frame 63 to move downward, so that the U-shaped pressing frame 63 moves downward to contact the hardware workpiece, so as to realize that the hardware workpiece is pressed by the U-shaped pressing frame 63 in the positioning frame 5, reducing the situation of the hardware workpiece sliding during the punching process.

[0035] As Figure 4 shown in the figure, in this embodiment, the discharging assembly 7 includes a telescopic rotary cylinder 71 fixedly installed on the top end surface of the base 1 and located between the discharging frame 2 and the circular feeding plate 4, and a connecting frame 72 installed on the top of the piston rod of the telescopic rotary cylinder 71. A pneumatic suction cup 73 is installed on the connecting frame 72, and the pneumatic suction cup 73 is used to suck up the processed workpiece.

[0036] Specifically, during use, the electrical equipment in this device is connected to an external PLC programmable control device through a control cable, and the linkage opening and closing of each electrical equipment is programmed through the external PLC programmable control device. The lifting cylinder 62, the telescopic rotary cylinder 71, and the pneumatic suction cup 73 are connected to an external pneumatic equipment.

[0037] After the U-shaped pressing frame 63 presses and fixes the hardware workpiece, by starting the first motor 11 and cooperating with the first lead screw 10, the first moving frame 9 can be driven to move back and forth in the sliding groove 8, so that the first moving frame 9 drives the high-speed motor 3 and the drill foot needle 18 to move back and forth. The second motor 12 cooperates with the second lead screw 13 to drive the second moving frame 14 to move left and right in the moving frame 9, so as to realize that the second moving frame 14 drives the high-speed motor 3 and the drill foot needle 18 to move left and right, so that the drill foot needle 18 is aligned with the through hole on the hardware workpiece, and the third motor 15 can cooperate with the third lead screw 16 to drive the third moving frame 17, the high-speed motor 3 and the drill foot needle 18 to move up and down, thereby adjusting the height of the drill foot needle 18.

[0038] By starting the high-speed motor 3 to drive the drill foot needle 18 to rotate, and controlling the third motor 15 to drive the high-speed motor 3 and the drill foot needle 18 to move downward, so that the drill foot needle 18 moves downward through the through hole on the upper part of the metal workpiece and applies pressure to the rivet on the lower part of the metal workpiece. This action will apply a huge pressure to the rivet, causing the rivet to deform on the opposite side of the through hole. The rivet undergoes plastic deformation under high pressure, and its end will expand outward or form a fixed head. When the rivet head is formed and tightened, the two metal parts are firmly connected together to complete the pressing work of the two workpieces. When processing a group of workpieces, another group of metal workpieces can be placed in the positioning frame 5 at the front end;

[0039] When the pressing is completed, the lifting cylinder 62 drives the U-shaped pressing frame 63 to move upward away from the metal workpiece. The driving motor 19 drives the processed metal workpiece to continue rotating until, when the metal workpiece rotates to the discharging frame 2, the telescopic rotary cylinder 71 controls the connecting frame 72 and the pneumatic suction cup 73 to rotate and move downward at the same time, so that the pneumatic suction cup 73 rotates and fits on the upper surface of the metal workpiece. By controlling the external air pressure device, the pneumatic suction cup 73 generates negative pressure to suck up the metal workpiece, and the telescopic rotary cylinder 71 drives the connecting frame 72 and the pneumatic suction cup 73 to rotate again, so that the pneumatic suction cup 73 drives the workpiece to move above the discharging frame 2. Then the external air pressure device simply injects air into the suction cup again to balance the internal and external air pressures, and the metal workpiece can be easily unloaded. The metal workpiece falls downward into the discharging frame 2 and is discharged outward through the discharging frame 2 to complete the overall pressing process of the metal workpiece. When a group of positioning frames are being discharged, the next group of metal parts are conveyed by another positioning frame 5 to the lower part of the drill foot needle 18 for processing to achieve more automated processing of the metal workpiece.

[0040] The above are only the preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
