Description

Technical Field

[0001] The invention relates to the technical field of special-shaped pipe processing, and in particular to a three-dimensional laser cutting and welding integrated device for special-shaped pipes. Background Art

[0002] Special-shaped pipe welding is a welding operation for non-traditional round pipes with special shapes. It mainly connects pipes with various special cross-sections, such as square, rectangular, elliptical, triangular and other irregular shapes, through welding processes to construct specific structures or components. In this process, it is necessary to accurately select welding methods, parameters and technologies based on the unique shape and material characteristics of the special-shaped pipe to ensure welding quality.

[0003] After searching, the Chinese patent document with the announcement number CN117206683B discloses a special-shaped tube welding device for fitness equipment, which belongs to the field of fitness equipment processing technology, including a base, a first drive component, a clamping component, a welding component and a second drive component. The clamping component is provided with two groups, and the two groups of clamping components are rotatably arranged on the upper part of the base, and are used to clamp the two groups of square tubes respectively. The first drive component is fixedly arranged on the upper part of the base, and is used to drive the two groups of clamping components to rotate synchronously, and then drive the two groups of square tubes to rotate synchronously. The welding component is arranged between the two groups of clamping components. Compared with the prior art, the embodiment of the present invention realizes automatic welding of the two groups of square tubes by rotating the two groups of square tubes compared with the welding component. At the same time, during the rotation of the two groups of square tubes, the distance between the welding component and the welding gap of the square tube can also be adaptively adjusted, thereby improving the welding effect between the two groups of square tubes and improving the welding quality.

[0004] This patent solves the problem in the prior art that square tubes are different from round tubes. As special-shaped tubes, the distance between the two square tubes and the welding gun is always changing during the rotation process, which causes the length of the laser beam acting on the welding gap to be easily too long or too short. Once the laser beam is too long or too short, it will cause a large difference in the melting temperature at the welding gap, thereby affecting the welding quality of the square tube.

[0005] However, when the device is in use, since laser cutting and laser welding usually require a cutting machine and a welding machine respectively, and the device only has a welding function and cannot cut, it lacks integration. Therefore, when processing the square tube, additional cutting equipment is required to cut the square tube, which makes the overall use cost higher. In addition, the positioning structure in its application is relatively simple, and it is difficult to quickly adjust the position of the square tube. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides an integrated three-dimensional laser cutting and welding device for special-shaped tubes, which solves the problem that welding and cutting in the prior art usually need to be achieved by a cutting machine and a welding machine respectively, lack of integration, and result in high overall use costs.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In order to better understand the present invention, the above contents are described in detail below in conjunction with specific embodiments. See also Figure 1-Figure 4 The embodiment of the present invention provides an integrated three-dimensional laser cutting and welding device for a special-shaped tube, comprising: a base 1, a driving mechanism 11 is installed inside the base 1, a moving mechanism 2 is installed on the top surface, and the moving mechanism 2 is connected to the driving mechanism 11, and the driving mechanism 11 is used to drive the moving mechanism 2 to move on the top surface of the base 1; a supporting assembly 4, which is installed on the top surface of the bottom, a motor 3 5 is installed on the top of the supporting assembly 4, and an adjusting plate 6 is connected to the output end of the motor 3 5, sleeves 7 are installed on both sides of the adjusting plate 6, and cutting heads 12 and welding heads 13 are respectively arranged inside the sleeves 7 on both sides, a clamping assembly 3, which is located on the top surface of the moving mechanism 2, and is used to clamp the special-shaped tube, and the moving mechanism 2 is used to drive the clamping assembly 3 and the special-shaped tube to move close to the sleeve 7.

[0034] During cutting, the motor 3 5 is used to drive the adjustment plate 6 to rotate, and the cutting head 12 is accurately moved to the top of the base 1. The special-shaped pipe is clamped and fixed by the clamping assembly 3 to ensure the stability of the position of the pipe during the cutting process. Then, the moving mechanism 2 starts to operate, driving the clamping assembly 3 and the special-shaped pipe to approach the cutting head 12, so that the cutting head 12 can directly act on the area to be cut of the special-shaped pipe; When the cutting position of the special-shaped tube is aligned with the cutting head 12, the clamping assembly 3 drives the special-shaped tube to rotate along its axial direction, so that the tube rotates one circle at a fixed speed, thereby completing the comprehensive cutting of its surface or section. At the same time, the equipment can also drive the moving mechanism 2 and the clamping assembly 3 to move as a whole through the operation of the driving mechanism 11, so that the special-shaped tube always maintains the best working position during the cutting process, ensuring the accuracy of the cutting path, and by adjusting the positions of the welding head 13 and the cutting head 12, the equipment can perform cutting and welding successively, thereby avoiding the problem of the simultaneous existence of welding equipment and cutting equipment, increasing the floor space and causing the enterprise's production cost to increase.

[0035] See also Figure 1 and Figure 7 One side of the sleeve 7 is threadedly connected with an adjusting rod 8, and the end of the adjusting rod 8 is rotatably connected with a pressing plate 9. The pressing plate 9 is movably arranged inside the sleeve 7, and one side of the pressing plate 9 is in contact with the cutting head 12 and the welding head 13.

[0036] By rotating the adjusting rod 8 forward or reverse, the pressing plate 9 can be retracted or pushed out of the sleeve 7. After the pressing plate 9 is retracted, the welding head 13 or the cutting head 12 can be removed from the sleeve 7. After the pressing plate 9 is pushed out, the welding head 13 can be pressed between the pressing plate 9 and the inner wall of the sleeve 7, thereby facilitating the loading and unloading of the laser head and facilitating later maintenance.

[0037] See also Figure 1 and Figure 2 The driving mechanism 11 includes a motor 4 1101, the output end of the motor 4 1101 is fixedly connected to a threaded rod 2 1102, the threaded rod 2 1102 and the motor 4 1101 are both installed inside the base 1, the outer wall of the threaded rod 2 1102 is threadedly connected to a slider 1103, and the top of the slider 1103 is connected to the moving mechanism 2. A mounting groove 1104 is opened in the middle of the base 1, and the slider 1103 is located in the mounting groove 1104.

[0038] Motor four 1101 is used to drive threaded rod two 1102 to rotate, and slider 1103 can move smoothly along the direction of threaded rod two 1102, thereby driving moving mechanism 2 to slide on the top surface of base 1, so that special-shaped pipes can be accurately positioned and adjusted in position during cutting or welding, without the need for additional guiding mechanism, thereby simplifying the design of the overall structure. By arranging driving components such as motor four 1101 and threaded rod two 1102 inside base 1, the entire driving mechanism 11 is effectively hidden, which not only protects the mechanical components from the influence of the external environment, but also saves the external space of the equipment, further optimizing the compactness of the equipment.

[0039] See also Figure 1 and Figure 2 The moving mechanism 2 includes a support plate 201, the middle of the bottom surface of the support plate 201 is fixedly connected to the top of the slider 1103, a motor 202 is installed in the middle of the top surface of the support plate 201, and a threaded rod 203 is installed on both sides of the motor 202, and the two sides are rotatably connected to the far sides of the threaded rod 203, and the bottoms of the two sides of the fixed plates 204 are respectively fixedly connected to the two sides of the top surface of the support plate 201, and the threaded rod 203 is connected to the clamping assembly 3. Guide strips 206 are fixedly connected to both sides of the middle of the bottom surface of the support plate 201, and guide grooves 1105 are opened on both sides of the middle of the top surface of the base 1, and the guide strips 206 are slidably connected in the guide grooves 1105.

[0040] By setting the motor 202 as a double-headed motor, the two threaded rods 203 can be driven to rotate at the same time, thereby realizing synchronous control of the clamping assemblies 3 on both sides. When the motor 202 drives the threaded rod 203 to rotate, the clamping assemblies 3 on both sides can synchronously move toward or away from the center, thereby achieving the purpose of moving the special-shaped tube close to the welding head 13 or the cutting head 12. When the special-shaped tube is firmly fixed by the clamping assembly 3, the moving mechanism 2 can smoothly move the special-shaped tube to the working area of ​​the welding head 13 or the cutting head 12 through the linkage movement of the slider 1103 and the support plate 201, thereby ensuring the accuracy of the processing position.

[0041] See also Figure 1 , Figure 3 and Figure 4The clamping assembly 3 includes a vertical plate 301, which is slidably connected to the top surface of the support plate 201, and the bottom of the vertical plate 301 is threadedly connected to the threaded rod 1 203. The top of the vertical plate 301 is rotatably connected to the mounting tube 302, and one side of the outer wall of the mounting tube 302 is installed with teeth. A motor 2 303 is installed on the top of one side of the vertical plate 301, and one side of the motor 2 303 is fixedly connected with a gear 304, and the teeth of the gear 304 are meshed, and a pressure rod 305 is threadedly connected to one side of the mounting tube 302, and the end of the pressure rod 305 is rotatably connected to a pressure strip 306, and one side of the pressure strip 306 is fixedly connected to a guide rod 307, and the guide rod 307 is slidably connected to the mounting tube 302. A limit ring 308 is fixedly connected to the middle of the outer wall of the mounting tube 302, and the limit ring 308 is rotatably connected to the inner top of the vertical plate 301. The top surface of the support plate 201 is fixedly connected to the slide rail 205. A slide groove 309 is opened in the middle of the bottom surface of the vertical plate 301, and the slide groove 309 is slidably connected to the slide rail 205.

[0042] The pressure strip 306 can be pushed out or retracted by operating the pressure rod 305. When the pressure strip 306 is pushed out, the special-shaped tube is firmly clamped inside the installation tube 302 to ensure that it remains fixed during the cutting or welding process. The setting of the guide rod 307 further standardizes the moving direction of the pressure strip 306 to ensure the accuracy and reliability of the clamping action. After the clamping is completed, the drive motor 2 303 is started, and the teeth of the outer wall of the installation tube 302 are driven to operate through the gear 304, so that the installation tube 302 and the clamped special-shaped tube rotate synchronously, thereby meeting the rotation operation requirements required for cutting or welding.

[0043] See also Figure 1 , Figure 5 and Figure 6 A collecting mechanism 10 is arranged above the middle part of the top surface of the base 1, and the collecting mechanism 10 includes a collecting box 1001, and a support leg 1002 is fixedly connected to the bottom of the outer wall of the collecting box 1001, and the bottom of the support leg 1002 is fixedly connected to the outer side of the middle part of the top surface of the base 1, and a slope 1003 is arranged on the bottom surface of the inner wall of the collecting box 1001, and an opening is provided at the bottom of one side of the outer wall of the collecting box 1001, and a recess is provided on the top surface of the inner wall of the opening, and a pull plate 1004 is movably connected in the opening, and a protrusion 1005 is provided on one side of the top surface of the pull plate 1004, and the protrusion 1005 is engaged in the recess, and the pull plate 1004 is close to the lower side of the slope 1003.

[0044] By designing the bottom surface of the inner wall of the collection box 1001 as an inclined slope 1003, the natural sliding of debris and welding slag can be facilitated. Therefore, the welding slag and debris generated during the cutting or welding process can be collected in the collection box 1001, avoiding the difficulty in cleaning caused by debris scattered in other parts of the equipment. The operator only needs to pull out the pull plate 1004 to quickly clean the debris, so there is no need to disassemble other equipment components, making the cleaning process convenient, and the mutual engagement of the protrusion 1005 and the recessed portion can prevent debris from being discharged from the opening.

[0045] See also Figure 1 and Figure 8 The support assembly 4 includes an upper bearing plate 401 and a lower bearing plate 402, the lower bearing plate 402 is fixedly connected to the top surface of the base 1, the motor three 5 is located on the top of the upper bearing plate 401, the bottom surface of the upper bearing plate 401 is fixedly connected to a guide rod 403, the bottom of the outer wall of the guide rod 403 is sleeved with a spring 404, and the guide rod 403 and the spring 404 are both located in the lower bearing plate 402, the bottom of the outer wall of the upper bearing plate 401 is fixedly connected to a floating bar 405, and the outer wall of the floating bar 405 is in contact with the outer wall of the collection box 1001.

[0046] When the raised portion 1005 of the special-shaped tube is pressed on the floating bar 405, the floating bar 405 will move according to the undulations of the surface of the special-shaped tube, and the displacement will be transmitted through the upper bearing plate 401 and the guide rod 403, thereby driving the cutting head 12 or the welding head 13 to move, ensuring that it maintains a suitable distance from the surface of the special-shaped tube. The design of the spring 404 provides a rebound force to help the system maintain balance and stability. No matter how the surface of the special-shaped tube changes, the floating bar 405 can adapt to its shape and automatically adjust the position of the cutting head 12 or the welding head 13, avoiding the problem of being too close or too far, and ensuring stability and processing quality during cutting and welding.

[0047] Working principle: When it is necessary to cut the special-shaped tube, firstly, one side of the special-shaped tube to be cut is inserted into the installation tube 302, and the other side of the special-shaped tube is in the middle of the collection box 1001, and the fixing strip is pressed on the top of the outer wall of the other side of the special-shaped tube, and then the pressure rod 305 is rotated to push the pressure strip 306 out, at this time, the pressure strip 306 can drive the guide rod 307 to move, and then the pressure strip 306 is close to the middle of the installation tube 302, at this time, the special-shaped tube can be clamped, and then the driving motor three 5 drives the adjustment plate 6 to rotate, and the mechanism cutting head 12 is moved to the top of the base 1, and the driving motor one 202 or the motor four 1101 is operated: When the motor 1 202 is driven, the motor 1 202 can drive the two threaded rods 1 203 to rotate. At this time, the threaded rod 1 203 will drive the vertical plate 301, the installation tube 302 and the special-shaped tube to approach the middle of the support plate 201 along the slide rail 205 at the same time, so that the special-shaped tube is close to the cutting head 12 of the mechanism. When the cutting part of the special-shaped tube is located directly below the cutting head 12, the cutting head 12 is opened and the motor 2 303 is driven. After the motor 2 303 is started, the gear 304 can be driven to rotate. The gear 304 and the teeth can be used to drive the installation tube 302 to rotate, thereby driving The special-shaped tube rotates. When the special-shaped tube rotates one circle, the cutting is completed. When the special-shaped tube rotates, the floating bar 405 contacts the special-shaped plate, so the convex part of the outer wall of the special-shaped tube will lift the floating bar 405 and the upper bearing plate 401. At this time, the guide rod 403 will move out of a part of the lower bearing plate 402, thereby compressing the spring 404. After the upper bearing plate 401 is lifted, it will drive the adjustment plate 6 and the cutting head 12 to move together, so that the distance between the structural cutting head 12 and the special-shaped tube can always be kept the same, thereby ensuring the cutting quality. When the motor 4 1101 is driven, the motor 4 1101 can drive the threaded rod 2 1102 to rotate, and the threaded rod 2 1102 can drive the slider 1103 to slide in the mounting groove 1104 in the base 1, and the support plate 201 can be driven to slide on the top surface of the base 1, thereby driving the vertical plate 301, the mounting tube 302 and the special-shaped tube to move and approach the structural cutting head 12, and then the motor 2 303 is driven to drive the mounting tube 302 and the special-shaped tube to rotate, so as to cut the special-shaped tube; When it is necessary to weld the special-shaped pipe, first drive the motor three 5 to drive the adjustment plate 6 to rotate, move the welding head 13 to the top of the base 1, and then insert the two sections of the special-shaped pipe to be welded into the two installation cylinders 302 respectively according to the steps of cutting the special-shaped pipe, and then drive the motor one 202 to drive the two threaded rods one 203 to rotate, and use the two threaded rods one 203 to drive the two vertical plates 301 to approach each other, at this time, the adjacent sides of the two special-shaped pipes can be close to the cutting head 12, and then drive the motor four 1101 to drive the threaded rod two 1102 to rotate forward or reverse, at this time, the slider 1103, the support plate 201 and the two sections of the special-shaped pipe can be driven to move, and the welding point between the two sections of the special-shaped pipe is moved to the welding head 13. Directly below, the two motors 2 303 and the welding head 13 are turned on at this time, and the two motors 2 303 can be used to respectively drive the two installation cylinders 302 and the two special-shaped tubes to rotate, and make the two special-shaped tubes in a relatively static state. When the special-shaped tube rotates one circle, the welding can be completed. At this time, the two sections of the special-shaped tube are combined into one, and then the pressure rod 305 on one side is rotated to cancel the clamping of one side of the special-shaped tube, and finally the motor 1 202 is driven to drive the threaded rod 1 203 to rotate so that the installation cylinder 302 and the special-shaped tube are away from the welding head 13, and then the motor 4 1101 is driven to drive the threaded rod 2 1102 to rotate so that the special-shaped tube is further away from the welding head 13, and finally the pressure plate 9 on the other side is rotated to cancel the clamping of the other side of the special-shaped tube, and the special-shaped tube can be removed; During the cutting and welding process, the debris or welding slag generated can fall into the collection box 1001 for collection. When the collection box 1001 needs to be cleaned, the pull plate 1004 is pulled out. At this time, the inclined surface 1003 can be used to guide the debris or welding slag to be discharged from the opening. After cleaning, the pull plate 1004 is inserted back, and the protrusion 1005 is engaged in the recessed part to seal the opening.
