[0025] Embodiment 1

[0026] See also Figure 1-Figure 5 As shown, the present embodiment provides a clamping anti-drooping electric pipe cutting device, comprising a cutting table 1, wherein first slide grooves 11 are provided at the parts of the cutting table 1 near both sides, wherein a first screw rod 12 is rotatably provided in one of the first slide grooves 11, and the first screw rod 12 is driven by a motor, and the first screw rod 12 is threadedly connected to the lower side of a moving frame 2, and a moving rod 21 is slidably provided in the moving frame 2, and a saw tooth 22 is installed on one side of the moving rod 21, and when the first screw rod 12 rotates, the moving frame 2 moves with the saw tooth 22, and the cutting position of the saw tooth 22 can be adjusted, and at the same time, the moving rod 21 descends with the saw tooth 22 to realize cutting, and the saw tooth 22 is driven to rotate by the motor.

[0027] The workpiece to be cut is placed on the upper side of the cutting table 1. Since a symmetrical unloading table 3 is arranged on the upper side of the cutting table 1, the upper side of the unloading table 3 has an arc-shaped structure, which can help the cylindrical workpiece to be placed stably.

[0028] A second slide groove 13 is symmetrically provided on the upper surface of the cutting table 1, and a clamping mechanism 4 is slidably connected in the second slide groove 13. The clamping mechanism 4 includes a support rod 41 slidably connected to the second slide groove 13. The upper side of the support rod 41 is connected to the outer side of the annular sleeve 42. Screws 44 are threadedly connected to both sides of the annular sleeve 42. One end of the screw 44 passes through the annular sleeve 42 and is rotatably connected to the clamping plate 43. A second screw rod 14 is rotatably arranged in the second slide groove 13. The second screw rod 14 is threadedly connected to the support rod 41. The second screw rod 14 is driven by a motor. Therefore, after the workpiece is placed, the annular sleeve 42 is moved to one end of the workpiece by moving the support rod 41. After the workpiece enters the annular sleeve 42, the rotation of the screw rod 44 drives the clamping plate 43 to fix the outer side of the workpiece, thereby improving the stability of the workpiece during cutting.

[0029] Furthermore, an internal tensioner is provided inside the annular sleeve 42, and the internal tensioner inside the annular sleeve 42 is moved by the cylinder 45 to fix the inside of the workpiece. Specifically, the internal tensioner includes an internal annular plate 46 connected to the piston end of the cylinder 45, and a first limiting groove 47 and a second limiting groove 48 intersecting each other are provided on the surface of the internal annular plate 46. Both ends of the first limiting groove 47 and the second limiting groove 48 are slidably provided with a sliding rod 49, and one end of the sliding rod 49 is connected to a clamping plate 491. The sliding rod 49 is used to slide the clamping plate 491 out of the first limiting groove 47 and the second limiting groove 48, so that the clamping plate 491 is clamped against the inside of the workpiece. The internal annular plate 46 can be extended to the inside of the workpiece by the drive of the cylinder 45 to fix the inside of the workpiece.

[0030] Furthermore, a third screw rod 463 is rotatably arranged in the first limiting groove 47, and both ends of the third screw rod 463 are respectively threadedly connected to the two sliding rods 49, and a symmetrical gear 2 466 is arranged on the third screw rod 463, and the gear 2 466 is located in a through groove 461 opened at the center of the inner annular plate 46, and a gear 3 467 is rotatably arranged on one side of the through groove 461, and the gear 3 467 is driven by a motor installed on the rear side of the inner annular plate 46, and when the gear 3 467 rotates, the gear 2 466 located on the lower side is meshed with the gear 3 467, so that the gear 2 466 rotates with the third screw rod 463, and the two sliding rods 49 slide automatically.

[0031] In addition, two fourth screw rods 465 are rotatably arranged at both ends of the second limiting groove 48, and the two fourth screw rods 465 are respectively threadedly connected to the other two sliding rods 49, and one end of the two fourth screw rods 465 is respectively connected to two gear ones 464. When the third screw rod 463 rotates with the gear two 466, the two gear ones 464 respectively mesh with the two sides of the gear two 466 located on the upper side, so that the gear one 464 rotates with the fourth screw rod 465, thereby achieving the sliding purpose of the other two sliding rods 49, wherein the third screw rod 463 is a bidirectional screw rod.

[0032] Embodiment 2

[0033] Taking into account that some saw teeth 22 are not sharp, and some workpieces are simply fixed on the outside during cutting, since the interior of the workpiece is a hollow structure, the workpiece is not supported internally, and the cutting cross-section of the workpiece is easily deformed during cutting. Therefore, the cylinder 45 is used to move the internal annular plate 46 to the inside of the workpiece, and the clamping plate 491 is used to support the inside of the workpiece, which effectively avoids the problem of deformation of the workpiece during cutting.

[0034] When the utility model is used in a numerically controlled machine tool, the cylinder 45 moves the internal annular plate 46 to the inside of the workpiece, and the third screw rod 463 rotates to make the gear 2 466 mesh with the gear 1 464, so that the slide bar 49 slides with the clamping plate 491, and the clamping plate 491 clamps the inside of the workpiece, and the screw rod 44 moves the clamping plate 43, and the clamping plate 43 fixes the outside of the workpiece, thereby improving the stability of the workpiece during cutting and preventing the workpiece from sagging during cutting. At the same time, the inside of the workpiece is supported to prevent the workpiece from being deformed when the workpiece is cut under the blunt saw teeth 22.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
