Detailed Embodiment
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] Please refer to Figures 1 to 7, the present utility model provides a technical solution: a steel pipe cutting device with a dual clamping structure, including an operating table 1. A vertical frame 2 is slidably connected to one side of the outside of the operating table 1. A lead screw 3 is rotatably connected to the inside of the operating table 1 corresponding to one end of the vertical frame 2. A vertical cylinder 4 is fixedly connected to the top of the vertical frame 2. A power output end of the vertical cylinder 4 is fixedly connected to a cutting base 5. A push block 6 is installed below the cutting base 5. A horizontal cylinder 7 is fixedly connected to one side of the outer wall of the vertical frame 2. A power output end of the horizontal cylinder 7 penetrates through the vertical frame 2 and is fixedly connected to one end of the push block 6. First fixing seats 8 and second fixing seats 9 are respectively fixedly connected to both ends of the top of the operating table 1. An active gear 10 and a driven gear 11 that are meshed with each other are respectively rotatably connected to the outer wall of the first fixing seat 8. The first fixing seat 8 is rotatably connected to a first workpiece groove 12 through a notch opened in its inner wall. The second fixing seat 9 is rotatably connected to a second workpiece groove 13 through a bearing opened in its inner wall. Reverse lead screws 14 are rotatably connected to the shells outside the first fixing seat 8 and the second fixing seat 9 corresponding to the first workpiece groove 12 and the second workpiece groove 13. Clamping members 15 are threadedly connected to both ends of the outer wall of the reverse lead screw 14. A support assembly 16 is installed between the first fixing seat 8 and the second fixing seat 9.
[0026] A pulley 501 and a cutting tool 502 are respectively rotatably connected to the inside of the cutting base 5. The pulleys 501 are distributed up and down and are connected by a belt 503. The cutting tool 502 is coaxially connected to one group of the pulleys 501.
[0027] The support assembly 16 is composed of a roller 1601 and a roller mounting bracket 1602. The roller 1601 is rotatably connected between the roller mounting brackets 1602. Electric push rods 1603 and telescopic sleeve rods 1604 are respectively installed at both ends of the outside of the two roller mounting brackets 1602. And both ends of the roller mounting brackets 1602 are correspondingly fixedly connected to the power output ends of the electric push rods 1603 and the shaft heads at the tops of the telescopic sleeve rods 1604. The telescopic sleeve rod 1604 is composed of several groups of circular shaft rods nested layer by layer, and the rods are slidably connected to each other.
[0028] In this embodiment, as Figure 1 and Figure 2As shown in the figure, two vertically distributed chutes are respectively opened at the positions of the operating platform 1 corresponding to the vertical frame 2, and vertically distributed sliders are opened at the bottom of the vertical frame 2. The vertical frame 2 extends into the chute corresponding to the lead screw 3 through one of the sliders. At the same time, the slider is sleeved on the surface of the lead screw 3 and forms a screw drive structure therewith. The vertical frame 2 forms a horizontal drive structure between the first fixed seat 8 and the second fixed seat 9 through the lead screw 3. The vertical frame 2, as a load-bearing member for installing the cutting component, can adjust its position through the drive structure of the lead screw 3, thereby driving the displacement of the cutting base 5, enabling the cutting tool 502 to better align with the predetermined cutting line of the steel pipe, and adjusting and processing according to different processes, improving the adaptability and flexibility of the device. The two groups of sliders provide more stable support for the drive of the vertical frame 2.
[0029] In this embodiment, as Figure 2 and Figure 3 shown, slide bars are opened at both ends of the vertical frame 2 corresponding to the vertical cylinder 4 at the top, and the slide bars all penetrate through one end of the cutting base 5. The cutting base 5 forms a lifting structure above the support assembly 16 through the vertical cylinder 4. First, the drive of the vertical cylinder 4 can adjust the cutting tool 502 to the optimal cutting height according to actual needs, ensuring the consistency and accuracy of the cutting effect. Second, the existence of the slide bars provides support for the reciprocating movement of the cutting base 5, maintaining the smooth operation of the cutting tool 502 at the bottom. At the same time, in the non-enabled state, the lifting structure of the cutting base 5 reserves enough operating space below, greatly reducing the probability of personnel coming into close contact with the cutting tool 502 and reducing the risk of injury caused by accidental contact with the cutting tool 502.
[0030] In this embodiment, as Figure 2 and Figure 3 shown, a strip-shaped rubber pad is provided on the surface of the push block 6, and a visual acquisition module fixed on the surface of the vertical frame 2 is installed at the top of the push block 6. There is a certain interval between the top of the push block 6 and the bottom of the slide bar opened on the vertical frame 2. The visual acquisition module installed at the top of the push block 6 can monitor the cutting process in real time. The push block 6 can push out the workpiece that has been cut on the surface of the support assembly 16 with the help of the push of the horizontal cylinder 7, replacing manual taking and reducing potential safety hazards.
[0031] In this embodiment, as Figure 4 and Figure 6As shown, the driven gear 11 is integrally connected to the first workpiece groove 12 through a shaft rod at its axis. Both the inside of the first workpiece groove 12 and the second workpiece groove 13 have circular notches. One end of the first fixed seat 8 and the first workpiece groove 12 is an open structure, and the other end is a solid surface. At the same time, the second fixed seat 9 and the second workpiece groove 13 are in a through structure. When placing the workpiece, it can pass through the second fixed seat 9 and the second workpiece groove 13 in a penetrating manner. The solid surface on one side of the first fixed seat 8 and the first workpiece groove 12 can be used to abut against one end of the workpiece. Their matching structure can adapt to workpieces of different lengths, improving the versatility and applicability of the equipment. At the same time, the first workpiece groove 12 realizes transmission through the structure of two groups of gear sets outside the first fixed seat 8. Since both ends of the workpiece are fixed by the clamping members 15 on the surfaces of the first workpiece groove 12 and the second workpiece groove 13, in the connection state of the same workpiece, the second workpiece groove 13 rotates simultaneously. This synchronous transmission method ensures the consistency of the rotation speed and direction of the workpiece during the cutting process, thereby improving the cutting accuracy.
[0032] In this embodiment, as Figure 5 shown, the clamping members 15 are semicircular, with a rubber layer coated on the inner wall. The clamping members 15 move relative to each other through the reverse lead screw 14 and are respectively slidably connected to the outsides of the corresponding first fixed seat 8 and the second fixed seat 9. At the same time, the clamping members 15 respectively form a rotating structure with the first workpiece groove 12 and the second workpiece groove 13. The shape of the clamping members 15 can better fit the outer wall of the circular steel pipe, and the rubber layer on its inner wall can increase the friction between the clamping members 15 and the steel pipe, further improving the clamping stability. And the distance between the clamping members 15 can be adjusted through the reverse lead screw 14, which enables the operator to easily adjust according to steel pipes of different diameters. And the clamping members 15 rotate with the workpiece, enabling the workpiece to maintain a uniform and stable rotation state during the entire cutting process. This helps the cutting tool 502 to always contact the workpiece at the same angle and speed, thereby improving the cutting accuracy and quality.
[0033] In this embodiment, as Figure 7As shown, the roller 1601 is fixedly connected to the axis center of the first bevel gear 1605 through the shaft head at one end thereof, and one end of each first bevel gear 1605 is meshed with a second bevel gear 1606 vertically distributed thereto. Moreover, the second bevel gears 1606 are coaxially connected. At the same time, the first bevel gear 1605 and the second bevel gear 1606 are rotatably connected inside one set of roller mounting brackets 1602, and relative rotational movement is formed between the rollers 1601; the relatively rotating rollers 1601 provide uniform and stable support for the workpiece. During the cutting process, the workpiece will not deform or displace due to uneven local stress, ensuring that the cutting tool 502 can accurately cut along the predetermined trajectory. It can absorb part of the vibration generated during the cutting process, reduce the shaking amplitude of the workpiece, thereby improving the cutting accuracy. At the same time, since the contact between the roller 1601 and the workpiece is rolling contact instead of sliding friction, the scratching of the workpiece surface can be greatly reduced. When the workpiece specifications are diverse, the clamping positions of steel pipes with different diameters between the clamping members 15 will change, and the height-adjustable roller 1601 can be adjusted accordingly according to the diameter of the workpiece to ensure that the roller 1601 can always be in good contact with the workpiece and provide stable support for it.
[0034] The usage method and advantages of the present utility model: For the steel pipe cutting device with a dual clamping structure, during use, the working process is as follows:
[0035] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown in the figure, it should be noted first that this cutting device is used for cutting steel pipes with a relatively long cutting length, effectively avoiding the problems of instability and shaking caused by unilateral fixation during the cutting of steel pipes with too large specifications. The steel pipe to be cut is passed through the notch where the second fixing seat 9 and the second workpiece groove 13 communicate until one end of the steel pipe abuts against the solid surface on one side of the first workpiece groove 12 of the first fixing seat 8. After the preliminary positioning of the pipe fitting is completed, the power supply is started. The reverse lead screws 14 respectively arranged in the first workpiece groove 12 and the second workpiece groove 13 are driven to rotate by their corresponding servo motors. The clamping members 15 move relatively through the rotating reverse lead screws 14 and slide on the outside of the first fixing seat 8 and the second fixing seat 9 respectively and approach both ends of the outer wall of the steel pipe at the same time until the steel pipe is fixed. According to the position of the steel pipe at this time, the power output end of the electric push rod 1603 starts the power supply to push one end of the roller mounting frame 1602 upward. At the same time, the telescopic sleeve rod 1604 at the other end of the roller mounting frame 1602 extends upward step by step until the roller 1601 can fit under the steel pipe. Since the steel pipes processed each time are of the same batch, the roller 1601 is only adjusted when replacing steel pipes of different specifications. After the adjustment of the roller 1601 is completed, according to the predetermined cutting line on the surface of the steel pipe, the lead screw 3 rotates after the power supply is started. The vertical frame 2 forms a transmission structure through the slider connected to the lead screw 3 and the lead screw 3, and then drives the vertical frame 2 to move to ensure that the cutting knife 502 on the cutting base 5 can be aligned with the predetermined cutting line of the steel pipe. The power supply is started, the upper pulley 501 is driven to rotate by the servo motor, and the lower pulley 501 rotates simultaneously through the transmission of the belt 503, and then the cutting knife 502 rotates. At the same time, the driving gear 10 outside the first fixing seat 8 rotates meshing with the driven gear 11 to drive the first workpiece groove 12 to rotate, and then the clamping member 15 on the surface of the first workpiece groove 12 drives the workpiece to rotate. Under the connection of the same workpiece, another group of second workpiece grooves 13 rotate inside the second fixing seat 9. The rotating workpiece effectively maintains stability through the clamping members 15 at both ends. And while the workpiece is rotating, the second bevel gear 1606 rotates through the servo motor. Under the coaxial connection, another group of second bevel gears 1606 rotates, and then meshes with two groups of first bevel gears 1605 integrally connected to the roller 1601 to rotate relatively. The relative rotation of the roller 1601 fits under the workpiece to provide support for it, effectively avoiding the problem of deformation during the cutting process, and at the same time absorbing the vibration generated during the cutting process and reducing the shaking amplitude of the workpiece. As the workpiece rotates, the cutting knife 502 cuts the steel pipe. After the cutting is completed, the vertical cylinder 4 raises the cutting base 5, and the clamping member 15 on the surface of the first workpiece groove 12 is separated from the outer wall of the pipe fitting again through the transmission of the reverse lead screw 14 during the relative movement. When the cutting is completed, the visual acquisition module (OV7670) above the push block 6 detects that the workpiece has been completely cut off, and then sends a signal to the control system to trigger the horizontal cylinder 7 to push the push block 6 to push out the cut part.After one cutting is completed, push the workpiece in the second workpiece groove 13 further, repeat the above cutting process, and complete the slitting of the steel pipe.
[0036] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present utility model and are not used to limit the present utility model.
