[0035] Example 1:

[0036] As Figure 1-7 shown, this device is an improvement based on the patent application No. 202321489393.8, with the patent name of an automatic punching and tapping machine. The improvement point is that the workpieces adsorbed by the vacuum suction head 6 sometimes do not maintain a perfect state and cannot be well transported and fixed on the workpiece fixing column base 2. At this time, it is not convenient for punching and tapping, resulting in a reduction in the operation efficiency of the device.

[0037] Therefore, on this basis, we add a mechanism that can automatically correct the position of the workpiece when it is adsorbed on the vacuum suction head 6, so that the vacuum suction head 6 can adsorb the workpiece in a preset state, thereby facilitating the stable placement of the workpiece on the workpiece fixing column base 2.

[0038] Specifically, the technical features of an existing automatic punching and tapping machine in the prior art are briefly restated below. The reference numbers will be different from those in the prior art patent application No. 202321489393.8, an automatic punching and tapping machine, but they are all the same device.

[0039] In the existing device, three workpiece fixing column bases 2 are horizontally fixedly connected to the top of the operation box 1. Auxiliary drilling grooves 31 are provided on the front surfaces of the three workpiece fixing column bases 2, facilitating the placement of workpieces on the workpiece fixing column bases 2. A tapping mechanism 7 and a punching mechanism 8 are fixedly installed on the operation box 1. The punching mechanism 8 punches the workpiece product on the rightmost workpiece fixing column base 2.

[0040] In this application, the workpiece is exemplified by a locking cap. Two rotary cylinders 10 are fixedly installed on the top of the operation box 1. Pressure plates 33 are fixedly connected to the two rotary cylinders 10. The two pressure plates 33 can respectively press the middle workpiece and the rightmost workpiece on the workpiece fixing column base 2, enabling the tapping mechanism 7 or the punching mechanism 8 to drill and tap the workpiece at a preset position.

[0042] Please refer to with emphasis Figure 1The front of the sliding plate 9 is fixedly connected to the first mounting plate 3, the front of the first mounting plate 3 is fixedly connected to three linear cylinders 4, the telescopic ends of the three linear cylinders 4 are fixedly connected to the vacuum head mounting plate 5, the vacuum head 6 is installed on the vacuum head mounting plate 5, and the three linear cylinders 4 are distributed on the first mounting plate 3 at equal intervals laterally.

[0043] Please focus on Figure 3 A vibrating loader 32 is provided on the right side of the work box 1, and a conveying slide 12 is fixedly connected to the top of the work box 1. The vibrating loader 32 transfers the workpiece to the conveying slide 12, and the left side of the conveying slide 12 is closed, so that the workpiece can reach the preset position, which is convenient for the vacuum suction head 6 to adsorb the workpiece. The workpiece is first sucked onto the vacuum suction head 6, and then transferred to the rightmost workpiece fixing column seat 2 and pressed, and punched by the punching mechanism 8. After the punching is completed, the punched workpiece is transferred to the middle workpiece fixing column seat 2, and then the rotating cylinder 10 presses the workpiece for tapping. The workpiece that has been tapped is transferred to the leftmost workpiece fixing column seat 2. Then it is transferred to the outside world.

[0044] Please focus on Figure 1 A workpiece posture adjustment mechanism is installed on the first mounting plate 3 to enable the workpiece adsorbed on the rightmost vacuum suction head 6 to be placed on the vacuum suction head 6 in a preset state.

[0045] Please focus on Figure 4 , Figure 5 and Figure 8, the workpiece attitude adjustment mechanism is structured as follows. A connecting plate 13 is fixedly connected to the first mounting plate 3. A second mounting plate 14 is fixedly connected to the connecting plate 13. Two first limit chutes 19 are provided on the second mounting plate 14. Two first racks 18 are slidably connected in the two first limit chutes 19 in the left-right direction. A rotating shaft 22 is rotatably connected to the second mounting plate 14. A second gear 24 is fixedly connected to the outer wall of the rotating shaft 22. The two first racks 18 are respectively disposed at the top and bottom of the second gear 24, and the two first racks 18 are both engaged with the second gear 24. A first hydraulic rod 16 is fixedly installed on the second mounting plate 14. The telescopic end of the first hydraulic rod 16 is connected to a second rack 20. A second slide rail plate 21 is fixedly connected to the second mounting plate 14. The second rack 20 is slidably connected in the second slide rail plate 21 in the left-right direction. A first gear 23 is fixedly connected to the outer wall of the rotating shaft 22. The second rack 20 is engaged with the first gear 23. Vertical plates 15 are fixedly connected to the bottoms of the mutually remote ends of the two first racks 18. The two vertical plates 15 are respectively disposed on both sides of the vacuum suction head 6. Stop bars 17 are fixedly connected to the bottoms of the mutually close sides of the two vertical plates 15. Slide sleeves 26 are fixedly connected to the tops of the two stop bars 17. Slide columns 27 are slidably connected in the slide sleeves 26 in the left-right direction. Arc-shaped guide plates 28 are fixedly connected to the mutually close sides of the two slide columns 27. Elastic members 25 are fixedly connected between the arc-shaped guide plates 28 and the slide sleeves 26. When the two stop bars 17 approach each other, place the workpiece on them. Then when the two stop bars 17 continue to approach, the two stop bars 17 will not contact each other, and at this time, the two arc-shaped guide plates 28 guide the workpiece and clamp the workpiece at the preset position.

[0046] In specific implementation: First, operate the vibrating feeder 32 to transfer the workpiece to the transfer chute 12, so that a row of workpieces is formed in the transfer chute 12.

[0047] At this time, the second hydraulic cylinder 30 is activated to move the sliding plate 9 to the right, so that the rightmost vacuum suction head 6 is placed above the workpiece at the leftmost side of the conveying slideway 12. At this time, the rightmost linear cylinder 4 is activated to move up and down, so that the vacuum suction head 6 is connected to an external vacuum tube to suck vacuum and adsorb the leftmost workpiece. Then, the linear cylinder 4 is stretched upward to lift the leftmost workpiece. When the workpiece is conveyed in the conveying slideway 12, its position and posture may shift or tilt, and it is necessary to correct the posture of the locking cap at the vacuum suction head. At this time, the first hydraulic rod 16 is activated to make the two retaining bars 17 approach each other, so that the workpiece can be placed above the two retaining bars 17 together. At this time, the vacuum suction head 6 breaks the vacuum, and the workpiece presses on the two retaining bars 17. Then, the two retaining bars 17 are made to approach further. At this time, the two arc-shaped guide plates 28 press on both sides of the workpiece and guide and position it, so that the workpiece presents a preset horizontal state. Then, the vacuum suction head 6 sucks vacuum to adsorb and fix the workpiece, completing the adjustment of the workpiece state. Then, the first hydraulic rod 16 is contracted to make the two retaining bars 17 move away from each other, so that the workpiece and the vacuum suction head can move downward safely.

[0048] Then, the workpiece is placed on the rightmost workpiece fixing column base 2, and the workpiece is pressed tightly by the rotating cylinder 10. The drilling mechanism 8 drills holes in the workpiece. Then, the workpiece is transferred to the middle workpiece fixing column base 2 by the vacuum suction head 6, and the workpiece at this position is pressed tightly by another rotating cylinder 10. At this time, the tapping mechanism 7 taps the holes that have been drilled. Then, the workpiece that has been drilled and tapped is transferred to the leftmost workpiece fixing column base 2 for an external device to take away.

Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present utility model, and these deformations and modifications shall fall within the protection scope of the present utility model.
