Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a four-chuck beveling pipe cutting machine. Background Technology

[0002] The chuck laser tube cutting machine has multiple chucks used to clamp and rotate the tube, so that the laser cutting components on the machine bed can process and cut the tube. The chuck laser tube cutting machine has the advantages of high processing accuracy and high efficiency.

[0003] To achieve multiple cutting modes / zero tail cutting, the chuck structure in a laser tube cutting machine with four chucks is capable of reciprocating along the length of the machine bed. Although the movement of each chuck structure can be set by the program, there is still a risk that the movement of the chuck structure may exceed the set maximum movement stroke due to operator error or program error, which could lead to a collision between the chuck structures.

[0031] This utility model provides a four-chuck beveling pipe cutting machine. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0032] Please see Figures 1-5This utility model provides a four-chuck beveling pipe cutting machine, including a bed 1, a gantry 19 mounted on the bed 1, a laser cutting assembly 2 mounted on the gantry 19 and capable of displacement along the X-axis, Z-axis, and A-axis of the bed 1, and a first chuck structure 31, a second chuck structure 32, a third chuck structure 33, and a fourth chuck structure 34 capable of reciprocating along the Y-axis of the bed 1; the first chuck structure 31 is provided with a first limiting plate 314, the second chuck structure 32 is provided with a second limiting plate 324, and the third chuck structure 33 is provided with a third limiting plate 334. The fourth chuck structure 34 is provided with a fourth limiting plate 344. The bed 1 is provided with two first buffer seats 101, second buffer seats 102, third buffer seats 103 and fourth buffer seats 104 arranged along the Y-axis. The first limiting plate 314 reciprocates between the two first buffer seats 101, the second limiting plate 324 reciprocates between the two second buffer seats 102, the third limiting plate 334 reciprocates between the two third buffer seats 103, and the fourth limiting plate 344 reciprocates between the two fourth buffer seats 104.

[0033] The first chuck structure 31, the second chuck structure 32, the third chuck structure 33, and the fourth chuck structure 34 can all reciprocate along the Y-axis of the bed 1. Compared with the traditional second chuck structure 32, which is fixed to the bed 1, it has more cutting modes. It can be moved to the right side of the gantry 19 through the second chuck structure 32 to achieve zero tail material processing and cutting, thus reducing production costs.

[0034] In addition, the laser cutting component 2 can achieve multi-axis motion, enabling it to perform straight pipe cutting or beveling cutting on pipes, thus meeting the processing requirements of pipes.

[0035] In practical applications, when each chuck structure reciprocates along the Y-axis of the bed 1, the limiting plates installed on them ensure that the corresponding chuck structure can only reciprocate between the corresponding two buffer seats. Specifically, for easy differentiation, the positions of each limiting plate and each buffer seat on the bed 1 are staggered.

[0036] The aforementioned four-chuck beveling pipe cutting machine, by setting multiple buffer seats on the bed 1 and setting limit plates corresponding to the buffer seats on each chuck structure, limits the movement path of the limit plates to the two buffer seats. Correspondingly, in the chuck structure, the movement path of each chuck structure can be limited. The movement stroke between the two buffer seats is the maximum movement stroke of each chuck structure, thereby preventing the problem of collision between chuck structures caused by the movement stroke of the chuck structure exceeding the set movement stroke.

[0037] Please see Figures 2-5In some embodiments, the first chuck structure 31 includes a first Y-axis side mounting plate 311 slidably connected to the bed 1, a first drive mechanism 312 disposed on the first Y-axis side mounting plate 311, and a first jaw 313, the clamping end of the first jaw 313 facing the second chuck structure 32, and a first limiting plate 314 disposed on the first Y-axis side mounting plate 311; the second chuck structure 32 includes a second Y-axis side mounting plate 321 slidably connected to the bed 1, a second drive mechanism 322 disposed on the second Y-axis side mounting plate 321, and a second chuck 323, and a second limiting plate 324 disposed on the second Y-axis side mounting plate 321. The third chuck structure 33 includes a third Y-axis side mounting plate 331 slidably connected to the bed 1, a third drive mechanism 332 disposed on the third Y-axis side mounting plate 331, and a third chuck 333. The third limiting plate 334 is disposed on the third Y-axis side mounting plate 331. The fourth chuck structure 34 includes a fourth Y-axis side mounting plate 341 slidably connected to the bed 1, a fourth drive mechanism 342 disposed on the fourth Y-axis side mounting plate 341, and a fourth jaw 343. The clamping end of the fourth jaw 343 faces the third chuck structure 33, and the fourth limiting plate 344 is disposed on the fourth Y-axis side mounting plate 341. The first drive mechanism 312, the second drive mechanism 322, the third drive mechanism 332 and the fourth drive mechanism 342 can all be driven by motors, gears and racks. Each chuck structure is fixedly connected to the corresponding Y-axis side mounting plate. Therefore, each Y-axis side mounting plate can drive the corresponding chuck structure and limit plate to move back and forth along the length of the side mounting bed 1.

[0038] Please see Figures 2-5 In some embodiments, a first limit switch 315 is provided on the first Y-axis side mounting plate 311, and a first sensing element 13 for sensing the first limit switch 315 is provided on the bed 1; a first limit switch 325 is provided on the second Y-axis side mounting plate 321, and a second sensing element 14 for sensing the first limit switch 325 is provided on the bed 1; a third limit switch 335 is provided on the third Y-axis side mounting plate 331, and a third sensing element 15 for sensing the third limit switch 335 is provided on the bed 1; a fourth limit switch 345 is provided on the fourth Y-axis side mounting plate 341, and a fourth sensing element 16 for sensing the fourth limit switch 345 is provided on the bed 1. Specifically, multiple sensing elements can be provided, that is, when the limit switch moves to the position of each sensing element, the sensing element can trigger the control mechanism to transmit the position of the corresponding chuck structure on the bed 1 to the system / control screen, so that the operator knows the position of the chuck structure relative to the bed 1. More specifically, each sensor needs to have an initial position, that is, after the pipe is processed, the limit switch can drive the chuck structure to move to the initial position.

[0039] Please see Figures 2-5 In some embodiments, a first anti-collision seat 316 is provided on the side wall of the first Y-axis side plate 311 facing the second chuck structure 32; a second anti-collision seat 326 is provided on the side wall of the second Y-axis side plate 321 facing the first chuck structure 31; a third anti-collision seat 336 is provided on the side wall of the third Y-axis side plate 331 facing the fourth chuck structure 34; and a fourth anti-collision seat 346 is provided on the side wall of the fourth Y-axis side plate 341 facing the third chuck structure 33. This anti-collision seat can extend the distance between the chuck structures, so that even if the chuck structures collide, only the anti-collision seat collides with the chuck structure or with another anti-collision seat, avoiding excessive impact on the chuck structure.

[0040] Please see Figure 2 and Figure 5 In some embodiments, anti-collision rubber 317 is provided on the side wall of the first anti-collision seat 316 facing the second chuck structure 32, and on the side wall of the fourth anti-collision seat 346 facing the third chuck structure 33. The anti-collision rubber 317 can mitigate impacts. As described above, when the anti-collision seat collides with the chuck structure or with another anti-collision seat, the provision of the anti-collision rubber 317 can prevent damage to the anti-collision seat / chuck structure.

[0041] Please see Figure 1 and Figure 2 In some embodiments, the bed 1 is provided with a guide rail 17 extending along the Y-axis direction, and the first Y-axis side mounting plate 311, the second Y-axis side mounting plate 321, the third Y-axis side mounting plate 331, and the fourth Y-axis side mounting plate 341 are all provided with sliders 318 that are slidably connected to the guide rail 17. The movement of the four Y-axis side mounting plates all uses the same set of guide rails 17, which makes the structure of the pipe cutting machine simpler and helps to reduce manufacturing costs.

[0042] Please see Figure 1 In some embodiments, the bed 1 comprises multiple horizontally extending tubes 11, multiple spaced-apart vertical tubes, and baffles 12 for connecting the upper and lower horizontal tubes 11. The multiple vertical tubes are located behind the baffles 12. The horizontal tubes 11, vertical tubes, and baffles 12 can be fixed by welding. The baffles 12 serve two purposes: firstly, to conceal the numerous horizontal tubes 11 and vertical tubes, improving the aesthetics of the tube cutting machine; secondly, to provide mounting positions for the various sensor plates. Please refer to [link to relevant documentation]. Figure 1The upper surface of the horizontal tube 11 located above is provided with a first cable chain 181, a second cable chain 182, a third cable chain 183, and a fourth cable chain 184. One end of the first cable chain 181 is used to fix it to the first Y-axis side mounting plate 311; one end of the second cable chain 182 is used to fix it to the second Y-axis side mounting plate 321; one end of the third cable chain 183 is used to fix it to the third Y-axis side mounting plate 331; and one end of the fourth cable chain 184 is used to fix it to the fourth Y-axis side mounting plate 341. Cables and air hoses of each chuck structure can be collected via the corresponding cable chains, preventing direct wear of cables and air hoses during operation, thus improving the service life of the pipe cutter and reducing maintenance frequency.

[0043] Please see Figure 3 In some embodiments, a dust extraction port is provided on the lower horizontal pipe 11, and a dust hood 41 is provided below the laser cutting assembly 2. The dust hood 41 is connected to the dust extraction port through a dust extraction pipe 42. This arrangement enables the cutting area to have a dust extraction function, preventing harmful gases and dust generated during pipe cutting from affecting the health of operators and reducing the environmental impact.

[0044] Please see Figure 3 In some embodiments, the laser cutting assembly 2 includes an X-axis slide 21 slidably mounted on the gantry 19, an X-axis drive mechanism 22 for moving the X-axis slide 21 along the X-axis direction, a Z-axis slide 23 slidably mounted on the X-axis slide 21, a Z-axis drive mechanism 24 for driving the Z-axis slide 23 along the Z-axis direction, an A-axis turntable 25 disposed at the lower end of the Z-axis slide 23, and a laser cutting head 26 mounted on the A-axis turntable 25. Under the control of the A-axis turntable 25, the laser cutting head 26 moves within a range of ±45° (…). Figure 3 (A schematic diagram showing the swing amplitude of the laser cutting head 26 is shown) The rotation changes the cutting angle, enabling the laser cutting head 26 to not only perform straight cutting of pipes but also beveling of pipes. Furthermore, combined with the drive of the X-axis drive mechanism 22 and the Z-axis drive mechanism 24, the laser cutting head 26 achieves precise positioning and cutting in three-dimensional space.
