[0002] In the current mechanical equipment production, metal pipe punching equipment is often used to process multi-angle precise hole of cylindrical, square and other tubular materials, which is usually composed of clamping module, rotary driving mechanism, punching power unit and numerical control system, and is widely used in the fields of petroleum pipeline, automobile exhaust system, building steel structure and the like. The core function thereof is to fix the pipe by the clamp, and to complete the punching requirement required by the design by cooperating with the high-frequency drill bit or laser cutting head. However, the existing technology still has obvious shortcomings in actual application: the traditional clamping structure often cannot balance the clamping stability of cylindrical pipe and the dynamic stability during rotation, especially the clamping deformation or radial deviation of slender pipe or thin-walled pipe is easy to occur; at the same time, most devices lack real-time collaborative control of rotary positioning and punching action, which leads to cumulative error of pipe rotation angle or uneven punching depth, thereby affecting the processing quality and requiring frequent shutdown calibration, which restricts the smoothness of continuous production.

[0028] Please refer to Figure 1 , two groups of symmetrical punching mechanism 3 include horizontal plate 31, slide rail 32, support plate 33, first motor 34 and puncher 35;Horizontal plate 31 lower end is bolted to frame body 1, slide rail 32 is arranged on the upper portion of horizontal plate 31, support plate 33 lower end is slidably connected with horizontal plate 31 through slide rail 32, first motor 34 is bolted to the side of support plate 33, puncher 35 rear end is inserted into the side of support plate 33, and the output end of first motor 34 is connected with puncher 35 through synchronous belt transmission;Support plate 33 is connected with electric push rod, and the electric push rod is bolted to frame body 1.

[0029] The device also includes a controller. The electric push rod, the first motor 34, the punch 35, and the clamping and pushing mechanism 4 are all electrically connected to the controller to perform punching operations according to a pre-set program. After the clamping and pushing mechanism 4 completes the clamping of the end of the pipe, the electric push rod pushes the support plate 33 to move along the slide rail 32, thereby bringing the punch 35 closer to the pipe. At the same time, the rotation of the first motor 34 drives the end of the punch 35 to rotate at high speed to perform the punching operation on the pipe. After a single punch is completed, the clamping and pushing mechanism 4 pushes the pipe to move and rotate after the punch 35 retracts, thereby adjusting the punching position.

[0030] As another embodiment, such as Figures 2 to 5 As shown, the clamping and pushing mechanism 4 includes a fixed frame 41, a second motor 42, a rotating rod 43, a drive disk 44, a clamp 45, and an extension plate 46. The lower end of the fixed frame 41 is bolted to the upper end of the vertical plate 2. An electric push rod is provided at the rear end of the fixed frame 41. The output end of the electric push rod passes through the fixed frame 41 and is bolted to the rear end of the second motor 42. The output end of the second motor 42 is inserted into the rotating rod 43. The end of the rotating rod 43 away from the second motor 42 is inserted into the rear end of the drive disk 44. The drive disk 44 is inserted into the turntable 5. The clamp 45 is rotatably connected to the outer periphery of the turntable 5. The upper end of the extension plate 46 is snapped into the lower end of the second motor 42.

[0031] The second motor 42 and the electric push rod are also connected to the controller via electrical signals. The electric push rod drives the second motor 42 to drive the clamp 45 to produce horizontal displacement, thereby driving the pipe to move horizontally. At the same time, the output end of the second motor 42 rotates to drive the rotating rod 43 to rotate, thereby driving the drive disk 44 to rotate. The rotation of the drive disk 44 drives the clamp 45 to clamp the pipe.

[0032] See Figures 3 to 5 The clamp 45 includes an outer ring 451, a sliding member 452, a rotating handle 453, and an arc frame 454.

The end of the sliding member 452 parallel to the drive disk 44 is slidably connected to the inner wall of the outer ring 451 and at the same time in contact with the surface of the turntable 5.

[0034] When the driving disc 44 is driven to rotate by the rotating rod 43, it drives the rotating disc 5 to rotate relative to the outer ring 451, and drives the sliding piece 452 to displace along the inner wall of the outer ring 451, so that the arc-shaped frames 454 at the ends of the three groups of sliding pieces 452 are close to or away from each other, and then the multiple groups of arc-shaped frames 454 clamp the pipe.

[0035] Referring to Figures 3 to 5 , the rear end of the sliding piece 452 is provided with multiple groups of vertically arranged arc-shaped protrusions 455 which protrude into the guide groove 6, and the sliding piece 452 is in sliding connection with the rotating disc 5.

[0036] Wherein, the arc-shaped protrusions 455 and the guide groove 6 are provided with lubricant, when the rotating disc 5 rotates, the spiral guide groove 6 rotates synchronously, and the displacement of the driving protrusions is limited by the spiral arc, so that the sliding piece 452 slides along the inner wall of the outer ring 451, and when the sliding piece 452 is disturbed, the rotating disc 5 cannot be driven to rotate;

[0037] When the diameter of the pipe is inconsistent front and back, the rotating handle 453 rotates when contacting the pipe, so that the arc-shaped frames 454 at both ends are in contact with the pipe, so that 6-point clamping can still be performed in the case of inconsistent pipe diameter.

[0038] Referring to Figure 4 , the outer ring 451 is provided with a through hole 456 around the outer periphery, and the sliding piece 452 is in sliding connection with the outer ring 451 through the through hole 456, and the through hole 456 is further provided with clamping grooves 457 which are uniformly arranged along the outer ring 451.

[0039] Wherein, the sliding piece 452 is provided with a sliding groove at both ends, and the through hole 456 is provided with a corresponding sliding pin, so that the sliding of the sliding piece 452 in the through hole 456 is more stable.

[0040] Referring to Figure 4 , the driving disc 44 is provided with a first electromagnetic pin 458 for driving the outer ring 451. The extension plate 46 is provided with a second electromagnetic pin 459 for fixing the outer ring 451.

[0041] Wherein the first electromagnetic pin 458 and the second electromagnetic pin 459 are connected with the controller electric signal, the lower part of the electromagnetic pin is provided with a battery, and the battery supplies power for the use of the electromagnetic pin, when the pipe clamp operation is carried out, the second electromagnetic pin 459 protrudes into the clamping groove 457 of the outer ring 451, and the first electromagnetic pin 458 is in the retracted state, so that the outer ring 451 is limited and cannot rotate, and the driving disc 44 can only drive the rotating disc 5 to rotate, so that the sliding part 452 is synchronously displaced along the through hole 456, and the pipe is clamped by the arc-shaped frame 454, when the pipe needs to be rotated for punching operation, the second electromagnetic pin 459 is retracted, and the first electromagnetic pin 458 protrudes into the clamping groove 457, so that the driving disc 44 drives the rotating disc 5 and the outer ring 451 to rotate synchronously, and then the arc-shaped protrusion 455 is opposite to the guide groove 6, and the sliding part 452 drives the arc-shaped frame 454 to rotate synchronously, and drives the pipe to rotate.

[0042] Working principle: when the pipe needs to be clamped, the second motor 42 drives the clamp 45 to displace horizontally, and drives the pipe to displace horizontally, and the output end of the second motor 42 rotates through the rotating rod 43 to drive the driving disc 44 to rotate, and then drives the sliding part 452 to displace along the inner wall of the outer ring 451, so that the arc-shaped frames 454 at the ends of the three groups of sliding parts 452 are close to each other to clamp the pipe, and then the electric push rod pushes the clamp 45 to displace so that the pipe enters the range of the punching mechanism 3 to perform punching operation and pipe horizontal position adjustment, when the pipe needs to be rotated, the second electromagnetic pin 459 is retracted, and the first electromagnetic pin 458 protrudes into the clamping groove 457, so that the driving disc 44 drives the rotating disc 5 and the outer ring 451 to rotate synchronously, and then the arc-shaped protrusion 455 is opposite to the guide groove 6, and the sliding part 452 drives the arc-shaped frame 454 to rotate synchronously, and drives the pipe to rotate.

[0043] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
