The screw is driven by a motor (the motor, screw, screw nut and the like are not shown in the drawing, and such structures are common machine tool guide rail structures). The screw is driven to rotate by the motor, and the screw nut moves along the screw shaft in the axial direction, thereby driving the C-shaped frame to move and reset.

[0049] (4) Three-axis drive module 9 arranged on the side of the rotary table 2 and symmetrically arranged with the movable grating 14.

[0050] The three-axis drive module 9 includes an X-axis arranged in parallel with the movable grating 14, a Y-axis arranged on the X-axis and along the vertical X-axis, and a Z-axis arranged vertically on the Y-axis. To achieve left and right, front and back, and up and down movement in space.

[0051] (5) The puncher 10 arranged on the vertical output end of the three-axis drive module 9.

[0052] The puncher 10 is welded and fixed with a C-shaped connecting frame on the side, and the connecting frame is fastened and installed on the output end arranged on the Z-axis through bolts.

[0055] (6) PLC programmable control system.

[0056] The PLC programmable control system is electrically connected with the motor of the rotary table 2, the motor of the movable grating 14, the three-axis drive module 9, and the puncher 10. To control the movement and reset of the movable grating 14, the deflection of the rotary table 2, the positioning of the drilling area of the three-axis drive module 9, and the opening and closing of the puncher 10.

[0057] According to the above technical scheme:

[0058] The space with a drill hole is placed on the plurality of electromagnetic suction cups 7 on the supporting plate 3, and the drilling surface faces upward. Since the workpiece 15 is a metal piece, it can be firmly adsorbed by the magnetic force of the electromagnetic suction cup 7, so as to realize the clamping of the workpiece 15.

[0059] Then the movable grating 14 moves from far away from the workpiece 15, to across the side of the workpiece 15, to the movable grating 14 reset and again far away from the workpiece 15. When the movable grating 14 is close to the side of the workpiece 15, when the laser grating 1401 emitted by the laser emitter of the movable grating 14 is not blocked at the same time, it indicates that the workpiece is placed side deviation; At this time, the turntable 2 is started to adjust the placement angle of the workpiece 15, until the movable grating 14 crosses the side of the workpiece 15, the laser is blocked at the same time, at this time the workpiece 15 is placed The adjustment is completed, the positioning of the workpiece is realized.

[0060] After that, the three-axis drive module 9 is started to adjust the corresponding position relationship between the punch head of the puncher 10 and the punching position on the surface of the workpiece 15. After the adjustment is completed, the punching is started. In the process of punching, the air suction pipe 11 sucks the peculiar smell generated by punching into the waste gas purifier 1313, and the peculiar smell in the waste gas is eliminated through the adsorption of the activated carbon box, so as to purify the working environment.

[0061] After the punching is completed, the electromagnetic chuck 7 is closed, and the workpiece 15 can be taken out.

[0062] In summary, the present scheme realizes the rapid clamping of the metal workpiece by the electromagnetic chuck 7; then the placement angle of the workpiece is adjusted by the cooperation of the movable grating 14 and the turntable 2, so as to realize the positioning of the workpiece; then the three-axis drive module 9 adjusts the punching position, so as to realize the single-sided multi-hole processing of the workpiece.

[0063] In the embodiment, the fence 4 is welded and fixed on the outer edge surface of the supporting plate 3, the upper end surface of the fence 4 is lower than the electromagnetic chuck 7, the bottom end of the fence 4 is lower than the supporting plate 3, the bottom wall of the fence 4 is provided with a discharging port 5, and the base 1 is provided with a material receiving disc 6. The fence 4 is used to collect the metal chips falling from the drilling, and the metal chips falling into the material receiving disc 6 through the discharging port 5, so as to realize the collection of the metal chips.

[0064] In the embodiment, the electromagnetic chuck 7 is provided with 2-10 groups, so as to ensure sufficient magnetic attraction force, and then ensure the stability of the workpiece 15.

[0065] The plurality of electromagnetic chucks 7 can be distributed in a ring array around the workbench axis of the turntable 2 (which is suitable for small-size workpieces 15 such as top plates and bottom plates, and is arranged in a ring in the drawings, and the number is 4), or can be arranged symmetrically in two columns on the supporting plate 3.

[0066] In the further embodiment of the present scheme, the turntable 2 is provided with a lifting assembly 8 corresponding to the electromagnetic chuck 7.

[0067] The lifting assembly 8 is any one of a hydraulic rod and an electric telescopic rod. Since the turntable 2 does not adjust the angle of the workpiece in a whole circle, the deflection of the turntable 2 does not affect the line laying.

[0068] In use, the workpiece 15 is attracted by the electromagnetic chuck 7. However, when the electromagnetic chuck 7 is positioned directly below the punching position, the electromagnetic chuck 7 interferes with the punching operation. At this time, the electromagnetic chuck 7 is turned off, and the corresponding lifting assembly 8 is retracted, so that the electromagnetic chuck 7 is lowered and the workpiece 15 is separated, thereby avoiding the punch of the puncher 10 from colliding with the electromagnetic chuck 7 and being damaged.

[0069] In a further embodiment of the present application, the support plate 3 is supported by a rotary bearing, and the support area is small and unstable. In order to improve the stability of the support plate 3, a ring-shaped support ring 16 is arranged on the base 1, and the support ring 16 is rotationally connected with the lower end surface of the fence 4, so as to expand the support range and make the workpiece more stable.
