Specific implementation mode

[0027] In order to further explain the technical solution of the utility model, it is elaborated in detail through specific embodiments below.

[0028] As Figure 1 shown, the utility model provides a direct - pressure type hardware punching foot device, including a base 1, a three - axis moving frame 2 arranged on the base 1, and a punching foot frame 5 is installed on the three - axis moving frame 2;

[0029] In this embodiment, an inclined discharge frame 3 is installed on the side surface of the base 1, the discharge frame 3 is located outside the telescopic rotary cylinder 6, and the discharge frame 5 is used for discharging the processed hardware parts;

[0030] In this embodiment, the three - axis moving frame 2 adopts a three - axis slide table module produced by Dongguan Yuancheng Automation Technology Co., Ltd.;

[0031] As Figures 1 to 5 shown, in this embodiment, a feeding tray 4 is arranged at the front end of the top of the base 1, and the feeding tray 4 can horizontally rotate along the top end surface of the base 1 to convey the hardware parts to the bottom of the punching foot frame 5 for pressing processing. A motor 11 is installed on the inner top of the base 1, and a retractable rotary cylinder 6 is fixedly installed at the edge of the top end surface of the base 1;

[0032] A punching stand 5 is installed at the front end of the three-axis mobile frame 2;

[0033] A plurality of positioning frames 10 equidistantly distributed in a ring shape are installed on the top surface of the feeding tray 4, and the positioning frames 10 are used to provide positioning for the hardware workpieces;

[0034] A swing arm 7 is installed on the top piston rod of the telescopic rotating cylinder 6, and a pneumatic suction cup 8 for adsorbing hardware is fixed on the swing arm 7;

[0035] A half gear 12 is fixedly sleeved on the top output shaft of the motor 11, and a transmission gear 13 meshing with the half gear 12 is provided on the left side thereof. A transmission shaft 14 rotatably connected to the inner side of the base 1 is fixedly installed on the inner ring of the transmission gear 13. The transmission shaft 14 vertically moves through the middle part of the bottom end surface of the base 1 and is connected to the middle part of the bottom end surface of the feed tray 4, so as to realize synchronous horizontal rotation of the feed tray 4 driven by the transmission shaft 14;

[0036] The punching foot frame 5 includes a column 51 installed at the front end of the three-axis mobile frame 2, an opening 52 vertically opened in the middle of the bottom end surface of the column 51, and an adjustment plate 53 rotatably installed in the opening 52. The adjustment plate 53 can be vertically rotated in the opening 52 to adjust the position of the drilling foot needle 55;

[0037] The front end face of the column 51 is penetrated with a positioning screw 56 threadedly connected thereto. The outer wall of the adjustment plate 53 is evenly provided with a plurality of sleeves 54 along the annular direction. A drilling pin 55 is installed in each sleeve 54. The outer diameter of each drilling pin 55 outside the adjustment plate 53 is designed to increase in sequence counterclockwise. The positioning screw 56 penetrates the front end face of the column 51 and then movably penetrates the front and rear end faces of the adjustment plate 53 and the rear end face of the column 51, so that the adjustment plate 53 can be positioned by the positioning screw 56 to reduce the random deviation and shaking of the adjustment plate 53.

[0038] The opening 52 passes through the left and right end surfaces of the column 51, and a distance is set between the drill pin 55 and the inner end surface of the opening 52 to reduce the collision between the drill pin 55 and the inner side of the opening 52 during the rotation process;

[0039] In this embodiment, the number of positioning frames 10 provided on the feeding tray 4 is 4, and each horizontal rotation of the half gear 12 at the bottom of the feeding tray 4 drives the transmission gear 13 to rotate horizontally 90°, so that the half gear 12 cooperates with the transmission gear 13 to sequentially feed each positioning frame 10 to the bottom of the punching bracket 5;

[0040] In this embodiment, the drill pin 55 is locked and fixed to the inner side of the sleeve 54 by a bolt 58, which facilitates the disassembly and assembly of the drill pin 55;

[0041] In this embodiment, a wing nut 57 is threadedly mounted on the positioning screw 56, and the wing nut 57 is closely attached to the rear end face of the column 51, which is convenient to further fix the positioning screw 56 through the wing nut 57 and improves the stability of the positioning screw 56 during use;

[0042] In this embodiment, a plurality of through holes matching the positioning screw 56 are formed in the adjusting plate 53, and the through holes and the sleeves 54 are distributed in one-to-one correspondence, which is convenient to fix the adjusting plates 53 at different positions by matching the positioning screw 56 with different through holes;

[0043] Specifically, the electrical devices in this device are electrically connected to an external PLC programmable controller through control cables, so as to program and control the opening and closing connections of each electrical device through the external PLC programmable controller. During use, stack the hardware parts with rivets and place them in the positioning frame 10, then start the motor 11 to drive the half gear 12 to rotate. The half gear 12 rotates one circle to drive the transmission gear 13 to rotate 90°, and the transmission gear 13 drives the feeding tray 4 to rotate 90° through the transmission shaft 14. The feeding tray 4 drives the positioning frame 10 and the hardware parts on the top to rotate and convey them to the lower part of the punching foot frame 5. During the process of the feeding tray 4 driving the hardware parts to convey, other hardware parts can be continuously placed in the front positioning frame 10.

[0044] As Figure 6 shown, in this embodiment, a limiting component 9 is arranged on the base 1. The limiting component 9 includes a support frame 91 installed on the top end face of the base 1 and a lifting cylinder 92 fixedly installed on the side surface of the support frame 91. A limiting frame 93 is installed on the bottom piston rod of the lifting cylinder 92, and the limiting frame 93 is located above the rear positioning frame 10;

[0045] Specifically, during use, when the hardware part moves to the lower part of the punching foot frame 5, the lifting cylinder 92 can be controlled to drive the limiting frame 93 to move downward to apply pressure to the hardware part, so that the hardware part is pressed and fixed in the positioning frame 10 by the limiting frame 93;

[0046] Then control the three-axis moving frame 2 to drive the column 51 to move. The column 51 drives the drill foot needle 55 to move and align with the rivet on the hardware part, and the three-axis moving frame 2 drives the column 51 and the drill foot needle 55 to move downward to apply pressure to the free end of the rivet on the hardware part, so that the end of the rivet undergoes plastic deformation to form a fixed upset head, thereby tightly connecting the two hardware parts together to achieve the riveting and fixing of the hardware parts;

[0047] When it is necessary to adjust and replace the drill foot pins 55 of different sizes, the wing nut 57 can be rotated to disengage from the positioning screw 56, and the positioning screw 56 is rotated to separate from the adjusting plate 53. Then, the adjusting plate 53 is rotated to adjust the downward drill foot pin 55, so that the outer diameter of the downward drill foot pin 55 changes to adapt to the rivets on different hardware. Then, the positioning screw 56 is rotated in the reverse direction through the adjusting plate 53 and the column 51, and the wing nut 57 is rotated and installed on the positioning screw 56 to complete the replacement of the drill foot pin 55, so that the drill foot pin 55 can adapt to rivets of different sizes;

[0048] After the hardware is completed with the riveting work, the lifting cylinder 92 is controlled to drive the limit frame 93 to separate from the hardware. When the hardware is driven by the motor 11 to move close to the telescopic rotary cylinder 6, the telescopic rotary cylinder 6 drives the swing arm 7 and the pneumatic suction cup 8 to rotate and fit on the upper surface of the hardware. The pneumatic device externally connected to the pneumatic suction cup 8 extracts the air inside the suction cup, thereby creating a vacuum environment lower than the external atmospheric pressure inside the suction cup. Since a vacuum is formed inside the suction cup, the external atmospheric pressure will press the workpiece against the surface of the suction cup, and the telescopic rotary cylinder 6 is controlled to drive the swing arm 7, the pneumatic suction cup 8 and the hardware to rotate, so that the hardware rotates above the discharge frame 3. When it is necessary to put down the workpiece, the release valve of the external pneumatic device is opened to allow external air to re-enter the suction cup interior, destroying the internal vacuum state. As the internal and external pressure difference disappears, the workpiece disengages from the suction cup under the action of gravity or with the assistance of external force, completing the discharging process. The hardware drops downward into the discharge frame 3 to complete the pressing work on the hardware.
