Detailed Implementation

[0025] This utility model provides a three-chuck laser tube 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.

[0026] Please see Figure 1This utility model provides a three-chuck laser tube cutting machine, including a side-mounted bed 1, a gantry frame 14 mounted on the side-mounted bed 1, a laser cutting assembly 2 that can reciprocate along the gantry frame 14 in the front-back and up-down directions, and a first chuck structure 31, a second chuck structure 32, and a third chuck structure 33 that can reciprocate along the side-mounted bed 1 in the left-right direction. The gantry frame 14 divides the side-mounted bed 1 into a feeding area and a receiving area. The feeding area is provided with multiple spaced mounting side seats 11, and the mounting side seats 11 are provided with a centering follow-up mechanism 4. The feeding area is also provided with multiple... The feeding assembly 5, corresponding to the centering follow-up mechanism 4, has its front end fixedly connected to the side hanging bed 1, and its rear end connected by a connecting rod 55. The feeding assembly 5 is used to convey the pipe from its rear end to its front end. The centering follow-up mechanism 4 is used to lift the pipe located on the feeding assembly 5. The receiving area is provided with a plurality of spaced reinforcing side seats 12, and a receiving mechanism 6 fixedly connected to the side wall of the side hanging bed 1 is provided between the reinforcing side seats 12. The receiving mechanism 6 is used to provide follow-up support and tilt the pipe located in the receiving area.

[0027] In practical applications, the boom is used to load the pipe to be cut onto the rear / upstream of the feeding assembly 5. The feeding assembly 5 operates and gradually conveys the pipes one by one to the front / downstream, i.e., the lifting position of multiple centering follow-up mechanisms 4. The centering follow-up mechanisms 4 lift the pipe to be cut to a position coaxial with the first chuck structure 31 and the second chuck structure 32. After the first chuck structure 31 and the second chuck structure 32 move to the set position, they clamp and fix the pipe. Then, the first chuck structure 31 pushes the pipe forward toward the laser cutting assembly 2 to achieve cutting. The cut pipe is clamped by the third chuck structure 33 and, with the cooperation of the receiving mechanism 6, is supported and assisted in unloading. Specifically, the receiving area is also equipped with multiple spaced U-shaped receiving racks. The extension direction of the multiple U-shaped receiving racks is parallel to the conveying direction of the pipe. Therefore, when unloading at an angle, the pipe on the receiving mechanism 6 will roll into the U-shaped receiving rack to achieve unloading.

[0028] Please see Figure 2In some embodiments, each of the multiple feeding components 5 includes a frame 51, a drive wheel 521 and a driven wheel 522 rotatably mounted on the frame 51, and a transport chain 523 wound around the drive wheel 521 and the driven wheel 522. Multiple limiting blocks 524 are provided on the outer surface of the transport chain 523, forming a storage slot between adjacent limiting blocks 524. The drive wheels 521 on the multiple feeding components 5 are connected by a drive shaft 531, which is driven by a rotation drive device 54. Specifically, multiple pipes are respectively confined in their respective storage slots. The storage slots prevent pipe displacement and ensure consistent conveying speed for each pipe. The rotation drive device 54 and the drive shaft 531 achieve synchronous operation of the multiple transport chains 523, resulting in a simple structure and high synchronization rate. In addition, the drive wheel 521, driven wheel 522 and transport chain 523 are conventional chain drive components. The material storage bay can be formed by assembling the material limiting block 524 on the transport chain 523. The manufacturing difficulty is small and the cost is low.

[0029] Please see Figure 2 In some embodiments, the frame 51 includes a crossbeam 511 parallel to the conveying direction of the pipe, a first vertical beam 512 fixedly connected to the front of the crossbeam 511, and a second vertical beam 513 fixedly connected to the rear of the crossbeam 511; adjacent second vertical beams 513 are connected by the connecting rod 55. Specifically, the crossbeam 511, the first vertical beam 512, and the second vertical beam 513 are all square tubing, which is lightweight and readily available. By using the front end of the crossbeam 511 to be fixedly connected to the side-mounted bed 1, and using the connecting rod 55 to fix multiple crossbeams 511, multiple feeding assemblies 5 form an easy-to-disassemble and easy-to-assemble structure, facilitating shipping and on-site installation.

[0030] Please see Figure 3In some embodiments, the drive wheel 521 is sleeved on the rotating shaft 5211, the rotating shaft 5211 is connected to the crossbeam 511 through two seated bearings 5212, and one end of the rotating shaft 5211 is connected to the transmission shaft 531 through a universal joint coupling 532; the rotation drive device 54 includes a motor bracket 541, a drive motor 542 mounted on the motor bracket 541, a drive sprocket 543 mounted on the output end of the drive motor 542, a driven sprocket 544 sleeved on one of the rotating shafts 5211, and a drive chain 545 wound between the drive sprocket 543 and the driven sprocket 544. When transporting pipes, the drive motor 542 drives the drive sprocket 543 to rotate. Under the transmission of the drive chain 545 and the driven sprocket 544, the shaft 5211 rotates, which in turn drives the drive wheel 521 on the shaft 5211 to rotate, providing power to the transport chain 523. In addition, when one shaft 5211 rotates, the power is transmitted to another shaft 5211 through the universal joint coupling 532, the drive shaft 531, and the universal joint coupling 532, thereby realizing the synchronous rotation of multiple transport chains 523.

[0031] Please see Figure 2 and Figure 4 In some embodiments, two axis-limiting plates 514 are provided at the front end of the crossbeam 511, and the two axis-limiting plates 514 are fixedly connected to the left and right side walls of the crossbeam 511 respectively. Both axis-limiting plates 514 are used to block the pipe from continuing to be conveyed forward. A stroke sensing mechanism 56 for sensing the pipe is provided behind the axis-limiting plates 514. The setting of the axis-limiting plates 514 can prevent the pipe from easily slipping / rolling out of the feeding assembly 5 due to the inertia of the pipe moving forward. The axis-limiting plates 514 are used to limit the movement of the pipe and improve safety. In order to automatically detect whether the pipe has been transported to the set position, the stroke sensing mechanism 56 is set. When the pipe triggers the stroke sensing mechanism 56, it means that the pipe has been transported to the position. At this time, the stroke sensing mechanism 56 feeds back a signal to the control system. The control system controls the rotation drive device 54 to stop working until the pipe is clamped and fed by the centering follow-up mechanism 4. The rotation drive device 54 restarts to realize the automatic feeding and transportation of the next pipe.

[0032] Please see Figure 4 In some embodiments, the stroke sensing mechanism 56 includes a support plate 561 fixed to the side wall of the crossbeam 511, a limit switch 562 disposed on the support plate 561, and a material receiving plate 563 disposed on the output end of the limit switch 562. Specifically, when the pipe is conveyed to the position of the material receiving plate 563, the material receiving plate 563 presses down, triggering the limit switch 562. The control system controls the operation of the support material receiving mechanism to support the pipe, making it easier for the chuck to clamp the pipe.

[0033] Please see Figure 5 and Figure 6 In some embodiments, each of the multiple receiving mechanisms 6 includes a base 61, a movable plate 62 vertically mounted on the base 61, a lifting drive 63 for driving the movable plate 62 to rise or fall, a receiving plate 64 with one end face rotatably connected to the upper part of the movable plate 62, and a receiving drive 65 fixed to the movable plate 62 for driving the receiving plate 64 horizontally or downwardly. The lifting drive 63 drives the movable plate 62 to rise and fall with the pipe, thereby changing the height of the receiving plate 64 relative to the pipe (especially for non-circular pipes). When the pipe needs to be supported, the receiving drive 65 drives the receiving plate 64 to a horizontal state, and then the movable plate 62 and the receiving plate 64 move up and down accordingly. When the pipe needs to be unloaded, the receiving drive 65 drives the receiving plate 64 to an inclined state, thereby guiding the pipe placed on the receiving plate 64 to the U-shaped receiving rack.

[0034] Please see Figure 6 In some embodiments, the lifting drive component 63 includes a lifting drive motor 631, a transmission gear 632 connected to the output end of the lifting drive motor 631, and a transmission rack 633 disposed on the front side of the base 61. The output end of the lifting drive motor 631 passes through the front and rear side walls of the movable plate 62. The transmission rack 633 extends vertically and is disposed on the base 61. The transmission gear 632 meshes with the transmission rack 633. In use, when the lifting drive motor 631 rotates forward, it drives the transmission gear 632 to rotate forward, and under the guidance of the transmission rack 633, the movable plate 62 and the receiving plate 64 rise synchronously. Conversely, when the lifting drive motor 631 rotates in the reverse direction, it drives the transmission gear 632 to rotate in the reverse direction, and the movable plate 62 and the receiving plate 64 descend synchronously. The above structure has high transmission efficiency and high transmission accuracy.

[0035] Please see Figure 5 In some embodiments, the receiving drive 65 is an inclined receiving cylinder. The cylinder body of the receiving cylinder is hinged to the lower part of the movable plate 62 via a first hinge seat 651, and the piston part of the receiving cylinder is hinged to the free end of the lower surface of the receiving plate 64 via a second hinge seat 652. The receiving cylinder rises and falls with the movable plate 62. When the output end is in a fully extended state, the receiving plate 64 is in a horizontal state, used to support the cutting of the pipe or assist in the unloading of the pipe; when the output end is in a fully retracted state, the receiving plate 64 is tilted downwards, used to guide the pipe as it falls into the U-shaped receiving frame.

[0036] Please see Figure 1In some embodiments, the side-mounted bed 1 is further provided with a first exhaust and dust removal port 101 penetrating its front and rear side walls; a support 13 is also fixedly connected to the side wall of the side-mounted bed 1, and the lower surface of one end of the gantry frame 14 is fixedly connected to the upper surface of the support 13; the support 13 is a hollow structure, and a second exhaust and dust removal port 131 penetrating its left and right side walls is provided on the support 13, and the second exhaust and dust removal port 131 and the first exhaust and dust removal port 101 are connected by an exhaust and dust removal pipe (not shown in the figure); the air inlet of the second exhaust and dust removal port 131 is located in the cutting area, and the air outlet of the first exhaust and dust removal port 101 is connected to the exhaust equipment. By opening a second exhaust dust removal port 131 on the support 13 below the gantry 14, the second exhaust dust removal port 131 is positioned closest to the laser cutting assembly 2. The exhaust dust removal pipe works in conjunction with the exhaust dust removal mechanism to directly extract metal dust generated during the laser cutting process, effectively reducing dust diffusion within the workshop, improving the working environment, and protecting the health of operators. Furthermore, in this embodiment, the second exhaust dust removal port 131 serves as an air inlet, and the first exhaust dust removal port 101 serves as an air outlet. This allows the exhaust equipment to be designed outside the pipe cutting machine or led out of the workshop via a pipe, with only the exhaust pipe exposed, thus optimizing the dust removal path and improving the aesthetics of the equipment.

[0037] In summary, this utility model improves the automation level of the pipe cutting machine by setting multiple feeding components 5 corresponding to the centering follow-up mechanism 4 in the feeding area, and using multiple feeding components 5 to transport the pipes one by one to the lifting position of the centering follow-up mechanism 4; and by setting a receiving mechanism 6 in the receiving area to provide follow-up support for the pipes during or after cutting, and to assist in tilting the material for unloading.
