Detailed Implementation

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] The following is combined with Figures 1 to 3 The embodiments of this utility model are described below.

[0026] like Figures 1 to 3 As shown, this embodiment relates to a pipe cutting device, including a horizontal base frame 100, a lifting frame 200, a laser cutting head 3, and a chuck device. The laser cutting head 3 is mounted on the lifting frame 200 and is used to cut the pipe on the chuck device. The chuck device includes a chuck body, a jaw assembly, and a protective cover 6. The chuck body is mounted on the horizontal base frame 100 and has a first pipe hole. The jaw assembly is mounted on the front end face of the chuck body and surrounds the first pipe hole. The protective cover 6 covers the jaw assembly and has a second pipe hole corresponding to the position of the first pipe hole on the protective cover 6.

[0027] Based on the above structure, during operation, the pipe to be cut is fixed in the chuck body on the horizontal base frame 100. Specifically, the pipe is placed through the first pipe hole and the second pipe hole. Then, the pipe is clamped and fixed by the jaw assembly located on the front face of the chuck body and surrounding the first pipe hole to prevent the pipe from shifting during cutting. Then, the laser cutting head 3 on the hoisting frame 200 performs laser cutting on the pipe. During this process, since the protective cover 6 is placed on the jaw assembly, most of the debris that splashes around during the cutting process will be blocked by the protective cover 6, thereby avoiding or reducing the debris flying towards the jaw assembly.

[0028] Therefore, when using this utility model, the pipe to be cut is fixed in the chuck body on the horizontal base frame 100 and placed on the first pipe hole and the second pipe hole. The chuck claw assembly located on the front face of the chuck body and surrounding the first pipe hole clamps and fixes the pipe. Then, the laser cutting head 3 on the hoisting frame 200 performs laser cutting on the pipe. During this process, since the protective cover 6 is placed on the chuck claw assembly, most of the debris that flies around during the cutting process will be blocked by the protective cover 6, thereby avoiding or reducing the debris flying towards the chuck claw assembly and accumulating on the chuck claw assembly, which could lead to malfunction of the chuck claw assembly.

[0029] The chuck body has a mounting plate on its front end, and the claw assembly is mounted on the front end of the mounting plate. The protective cover 6 is mounted on the side wall of the mounting plate. Based on the above structure, during installation, the claw assembly is first mounted on the mounting plate, then the protective cover 6 is mounted on the side wall of the mounting plate, and finally the mounting plate is mounted on the front end of the chuck body. This achieves modular installation. At the same time, since the protective cover 6 is mounted on the side wall of the mounting plate, it provides protection for the claw assembly from both the front and side, thus improving the protection effect.

[0030] The protective cover 6 can be installed in various ways. In one embodiment, the protective cover 6 is snapped onto the side wall of the mounting plate. In this embodiment, the protective cover 6 is screwed onto the side wall of the mounting plate for a more stable installation.

[0031] The protective cover 6 has a first opening on its front end face, and a front cover plate is detachably mounted on the first opening. The front cover plate has a second pipe hole. Thus, when the claw assembly needs to be repaired, it is not necessary to disassemble the entire protective cover 6. Only the front cover plate needs to be removed to expose a part of the claw assembly structure, which makes it easier for maintenance personnel to repair the internal claw assembly.

[0032] The chuck assembly includes a first guide rail, a slider, and a guide wheel. The first guide rail is set on the front end face of the mounting plate and extends from the periphery of the mounting plate toward the first pipe hole. The slider is slidably mounted on the first guide rail, and the guide wheel is set on the side of the slider near the first pipe hole. The guide wheel is used to abut against the pipe, and the slider is used to slide along the guide rail. The slider can drive the guide wheel to move closer to or away from the pipe on the first pipe hole. A displacement sensor is set on the chuck body and is electrically connected to the control system. The displacement sensor is located on the side of the protective cover 6 and corresponds to the slider. A second opening is set on the side wall of the protective cover 6 corresponding to the position of the displacement sensor. In this way, the displacement sensor can detect the distance of the slider assembly inside the protective cover 6 through the second opening to identify whether the slider is in the clamping position or the reset position. This allows the control system to determine the working status of the chuck assembly through the detection data of the displacement sensor. Thus, with the above structure, even when the protective cover 6 is set outside the chuck assembly, the external displacement sensor can still detect the distance of the internal slider to ensure the fault detection requirements of the equipment.

[0033] The chuck body is mounted on the side of the horizontal base frame 100. An exhaust vent is located below the chuck body on the side of the horizontal base frame 100, and this exhaust vent is connected to an exhaust fan. An inclined guide plate 16 is mounted on the exhaust vent, and ventilation openings are provided on the inclined guide plate 16. Thus, when the laser cutting head 3 performs laser cutting on the pipe, some debris is directly drawn away by the ventilation openings, effectively reducing the amount of debris splashing in all directions, thereby reducing the amount of debris flying towards the chuck assembly and preventing debris accumulation on the chuck assembly. In addition, some debris bounces onto the surface of the inclined guide plate 16 and slides down along its surface, preventing debris from accumulating on the inclined guide plate 16 and clogging the ventilation openings.

[0034] The horizontal base frame 100 has an air outlet 18 connected to an exhaust fan on its side. The air outlet 18 and the exhaust fan are located on both sides of the horizontal base frame 100 and are connected by an exhaust duct 19 that runs through the horizontal base frame 100. In this structure, the exhaust duct 19 runs through the horizontal base frame 100 to connect the air outlet 18 and the exhaust fan respectively, so that the air outlet 18 and the exhaust fan are located on both sides of the horizontal base frame 100. The side of the exhaust fan is the cutting side, and the side of the air outlet 18 is the non-cutting side. This makes it easy to place the exhaust fan on the non-cutting side without occupying the space on the cutting side of the horizontal base frame 100, and without causing movement interference to other components.

[0035] The chuck body is equipped with a debris collection groove 20. When the laser cutting head 3 laser cuts the pipe, some of the vertically falling debris will fall directly into the debris collection groove 20. At the same time, some debris will bounce onto the surface of the inclined guide plate 16 and slide down along the surface of the inclined guide plate 16 into the debris collection groove 20 to prevent debris from polluting the working environment of the employees.

[0036] Among them, such as Figure 2 As shown, the pipe cutting equipment also includes a material support mechanism, which includes a mounting base 21, a lifting cylinder 22, a roller seat 23, and a reducing wheel 24. The mounting base 21 is mounted on the horizontal base frame 100 and is located on one side of the chuck device. The lifting cylinder 22 is mounted on the mounting base 21 with its drive end facing upwards. The bottom of the roller seat 23 is mounted on the drive end of the lifting cylinder 22. The reducing wheel 24 is rotatably mounted on the roller seat 23. During operation, the chuck assembly clamps the head of the pipe. Then, according to the diameter of the pipe to be processed, the support contact surface of the reducing wheel 24 is rotated and adjusted. The lifting cylinder 22 then drives the reducing wheel 24 to rise. During pipe cutting, the reducing wheel 24 can effectively support the pipe, reducing the swaying of the pipe in the up, down, left, and right directions, and improving cutting accuracy.

[0037] Among them, such as Figure 2As shown, the material support mechanism also includes a connecting plate 25 and a lifting guide column 26. The connecting plate 25 is horizontally mounted on the mounting base 21, and the lifting guide column 26 is vertically mounted on the connecting plate 25. The lifting guide column 26 can slide up and down relative to the connecting plate 25. The top of the lifting guide column 26 is connected to the bottom of the roller seat 23. The driving end of the lifting cylinder 22 passes through the connecting plate 25 and is connected to the bottom of the roller seat 23. Thus, when the lifting cylinder 22 drives the variable diameter wheel 24 to move up and down, the lifting guide column 26 plays an auxiliary guiding role, thereby improving the stability of the variable diameter wheel 24 moving up and down.
