Description
Technical Field
[0001] The utility model relates to the technical field of pipe processing, and particularly relates to a pipe laser processing device. Background Art
[0002] The statements in this part merely provide background technical information related to the utility model, and do not necessarily constitute prior art.
[0003] Some flow meters in the prior art (such as vortex flow meters, rotameters, and magnetic flow meters, etc.) install flow detection elements in a section of pipeline, so that the formed integral part can be quickly installed at the required detection position. In order to improve production efficiency, the pipeline is pre-processed by cutting, punching, etc., and then assembled with the flow detection element to form a pipeline with a flow detection function. During use, the entire pipeline is installed in the pipe section to be detected.
[0004] When processing pipelines, due to the advantages of high processing accuracy, fast processing speed, and smooth processing cuts, laser processing gradually replaces traditional mechanical tool processing. For the processing of flow meter pipes, most of the current processing equipment manually transports the pipes to the processing area (loading), the laser processing equipment performs the processing operation, and then manually transfers the processed pipes (unloading). Since the lengths of the pipes are not uniform, the clamping actions during processing are affected, thereby reducing the work efficiency. At the same time, the loading actions are generally assisted by some transfer tools, and these transfer tools cannot handle pipes with too large length differences, further reducing the processing efficiency.

Specific embodiments
[0029] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0030] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present utility model. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs.
[0031] As introduced in the background art, for the processing of flowmeter pipes, since pipes of different lengths need to be processed to meet the requirements of different models of flowmeters, and the difference in pipe length will affect the feeding efficiency and the efficiency of the clamping action during processing, resulting in low efficiency of the current processing method.
[0032] The following embodiments provide a pipe laser processing equipment. The pipes are manually placed in the conveying unit in sequence, and the conveying unit transfers the workpieces one by one to the processing unit to achieve laser processing. The width between the two conveying lines of the conveying unit can be changed, so as to meet the change in pipe length, so that pipes of different lengths can be reliably transported to the processing unit, thereby reducing the impact of the change in pipe length on the processing efficiency.
[0033] A laser processing device for pipe materials, comprising a processing unit and a conveying unit:
[0034] The processing unit includes a robot located on the side of the frame and an auxiliary processing component movably connected to the frame. The auxiliary processing component has a feeding chuck for clamping and fixing the workpiece.
[0035] The conveying unit includes a conveying line and a lifting and positioning mechanism located at the end of the conveying line. The lifting and positioning mechanism is located at one end of the frame. The conveying line includes a fixed-side conveying line and a moving-side conveying line arranged in parallel. The moving-side conveying line can move along a linear guide rail in a direction approaching or away from the fixed-side conveying line, so as to change the distance between the fixed-side conveying line and the moving-side conveying line.
[0036] The pipe materials to be processed have differences in length. In this embodiment, these pipe materials with length differences are uniformly referred to as workpiece 101.
[0037] As Figure 1 shown, the processing unit includes a robot 2 arranged on the side of the frame 8. The robot 2 in this embodiment is a robotic arm. The end of the robotic arm is connected to a linear module 3. A laser processing head 5 is provided on the linear module 3. The robot 2 is fixed to the ground through a robot base 4. On the top of the frame 8, a first linear guide rail 6 and a second linear guide rail 7 are arranged in parallel. An auxiliary processing component is slidably connected to the first linear guide rail 6 and the second linear guide rail 7. The auxiliary processing component has a feeding chuck 9.
[0038] The robot 2 is connected to the electric control cabinet 1. The laser is emitted by a laser device in the electric control cabinet 1 and is transmitted to the laser processing head 5 through an optical fiber cable. The laser processing head 5 moves linearly driven by the linear module 3 to meet the processing requirements. For example, to achieve the feeding operation during processing.
[0039] The conveying unit includes a conveying line and a lifting and positioning mechanism located at one end of the conveying line. The end of the conveying line faces one end of the frame 8. The conveying line includes a bracket. On the top of the bracket, a fixed-side conveying line 10 and a moving-side conveying line 15 are arranged in parallel. A lifting and positioning mechanism is provided at one end of the two conveying lines. The lifting and positioning mechanism is close to the frame 8 of the processing unit. The fixed-side conveying line 10 is fixedly connected to the top of the bracket. The two ends of the moving-side conveying line 15 are respectively movably connected to the top of the bracket through a third linear guide rail 11 and a fourth linear guide rail 12.
[0040] A first guide rail locking device 13 is provided on the third linear guide rail 11, and a second guide rail locking device 14 is provided on the fourth linear guide rail 12, which are used to lock when the moving-side conveying line 15 moves along the third linear guide rail 11 and the fourth linear guide rail 12 to a set position, and are used to lock the distance between the fixed-side conveying line 10 and the moving-side conveying line 15 after the distance between them is changed.
[0041] The directions of the first linear guide rail 6, the second linear guide rail 7, the third linear guide rail 11, and the fourth linear guide rail 12 are the same.
[0042] As Figure 2 shown, the conveyor line includes a fixed-side conveyor line 10 and a moving-side conveyor line 15. The moving-side conveyor line 15 can move along the third linear guide rail 11 and the fourth linear guide rail 12 to a set position, realizing the change of the distance between the fixed-side conveyor line 10 and the moving-side conveyor line 15, and further adjusting the transport width that the conveyor line can accommodate. When there are differences in the lengths of the workpieces 101, the transport requirements can be met.
[0043] The fixed-side conveyor line 10 includes a first driving sprocket 24 and a first driven sprocket 28 on a bracket arranged in the horizontal direction. The first driving sprocket 24 and the first driven sprocket 28 are movably connected by a first conveyor chain plate 26. A first chain support plate 27 is provided outside the first conveyor chain plate 26. The first driving sprocket 24 rotates around a transmission shaft 23 driven by a first motor reducer 25. The rotational motion drives the first driven sprocket 28 to rotate through the first conveyor chain plate 26. The first driven sprocket 28 rotates around a driven shaft 29, and a driven bearing is provided on the driven shaft 29. The driven bearing is located in a driven bearing seat (in this embodiment, it is the first driven bearing seat 32).
[0044] As Figure 3 shown, the moving-side conveyor line 15 includes a second driving sprocket 33 and a second driven sprocket 38 on a bracket arranged in the horizontal direction. The second driving sprocket 33 and the second driven sprocket 38 are movably connected by a second conveyor chain plate 36. A second chain support plate 37 is provided outside the second conveyor chain plate 36. The second driving sprocket 33 rotates around a transmission shaft driven by a second motor reducer 35. The rotational motion drives the second driven sprocket 38 to rotate through the second conveyor chain plate 36. The second driven sprocket 38 rotates around a driven shaft, and a driven bearing 30 is provided on the driven shaft. The driven bearing 30 is located in a driven bearing seat (in this embodiment, it is the second driven bearing seat 31).
[0045] In this embodiment, the first conveyor chain plate 26 and the second conveyor chain plate 36 have the same structure and synchronous motion. They both include a chain body and a transport block connected to the chain body. One end of the workpiece 101 is placed in two adjacent groups of transport blocks on the first conveyor chain plate 26, and the other end of the workpiece 101 is placed in two adjacent groups of transport blocks on the second conveyor chain plate 36. When the two conveyor chain plates move synchronously, their respective transport blocks form a transport station to transport the workpiece 101 into the lifting and positioning mechanism. The transport block is a plate-shaped part connected to the chain body, used to form a protrusion on the transport plane of the chain body to prevent the workpiece 101 from rolling. The specific shape is not limited in this embodiment.
[0046] As Figure 2As shown, the jacking and positioning mechanism includes a power module connected to the bracket. Under the guidance of the lifting rod group 21 and the linear bearing group 22, the power module drives the jacking plate 16 to move up and down in the vertical direction. The upper surface of the jacking plate 16 is provided with a roller group for carrying the workpiece 101.
[0047] The roller group includes a first roller group 17 and a second roller group 18 arranged in parallel. The rollers in the two roller groups are arranged in a "V" shape and have roller shafts 19, so that the rollers can rotate around their respective roller shafts 19.
[0048] Since the workpiece 101 is a pipe section with a certain length and its outer surface is cylindrical, the rollers in each set of roller groups are arranged in a "V" shape, which can better carry the workpiece 101. The number of roller groups is not limited. In this embodiment, two common roller groups are taken as an example to illustrate the solution. The number of roller groups can also be appropriately increased according to the length of the workpiece 101 to obtain a more stable jacking and carrying effect.
[0049] The specific type of the power module is not limited. In this embodiment, the power module can be a lifting electric cylinder 20.
[0050] The roller group in the jacking and positioning mechanism receives the workpiece 101 from the conveyor line and jacks it up to the clamping height where the feeding chuck 9 is located. Then, the clamping chuck 9 acts to clamp and fix it in the processing unit. Furthermore, it can be driven by the auxiliary processing component to achieve linear motion, and then the laser processing of the clamped and fixed pipe is realized by using the robot 2.
[0051] As Figure 4 shown, the auxiliary processing component includes a sliding base 39 slidably connected to the first linear guide rail 6 and the second linear guide rail 7. A transmission component 40 is provided on the sliding base 39. The transmission component 40 includes at least two sets of transmission mechanisms. One set of transmission mechanisms drives the feeding chuck 9 together with the fixed workpiece 101 to move linearly along the direction where the first linear guide rail 6 and the second linear guide rail 7 are located, for adjusting the processing position in the axial direction of the workpiece 101; the other set of transmission mechanisms drives the feeding chuck 9 together with the fixed workpiece 101 to rotate, for changing the relative position of the surface of the workpiece 101 relative to the laser processing head 5 during processing.
[0052] At least one of the first linear guide rail 6 and the second linear guide rail 7 is a linear guide rail with a rack. Correspondingly, one set of transmission mechanisms in the transmission component 40 can be a reducer driven by a motor. The gear on the output shaft of the reducer meshes with the first linear guide rail 6 or the second linear guide rail 7 to drive the sliding base 39 together with the feeding chuck 9 and the fixed workpiece 101 to achieve linear motion. Correspondingly, the other set of transmission mechanisms in the transmission component can also be a reducer driven by a motor, which drives the feeding chuck 9 and the fixed workpiece 101 to achieve rotational motion.
[0053] It also has a shield 41, and the transmission assembly 40 is protected within the shield 41.
[0054] In this embodiment, the moving-side conveyor line 15 can move along the third linear guide rail 11 and the fourth linear guide rail 12 to a set position, realizing the change of the distance between the fixed-side conveyor line 10 and the moving-side conveyor line 15, and further adjusting the transport width that the conveyor line can achieve. When there are differences in the lengths of the workpieces 101, the transport requirements can be met.
[0055] During use, the operator sequentially places the workpieces 101 of this batch to be processed on the conveyor line, and adjusts the distance between the fixed-side conveyor line 10 and the moving-side conveyor line 15 according to the length of the workpiece 101. After adjustment, the guide rail locking devices 13 and 14 are locked and fixed.
[0056] The workpiece 101 is driven by the conveyor line to the lifting and positioning mechanism, and is lifted to a height where the center of the workpiece 101 is aligned with the center of the feeding chuck 9 for clamping the workpiece 101. The feeding chuck 9 can be a four-jaw feeding chuck to ensure that the clamping force required for processing can be provided.
[0057] The workpiece 101 is driven by the transmission assembly 40 to perform a rotational motion or a linear motion in a clamped and fixed state, and the robot 2 carries the laser processing head 5 to perform laser processing on the workpiece 101. In this embodiment, cutting processing is taken as an example.
[0058] In the above structure, the conveyor line is arranged at a 90° angle to the direction of the machine frame, and the lifting and positioning mechanism at the end of the conveyor line is located at one end of the machine frame. After the pipe (workpiece) on the conveyor line reaches the lifting and positioning mechanism, one end of the pipe faces the feeding chuck on the machine frame. The feeding chuck can be driven by the auxiliary processing assembly to achieve butt-joint with one end of the pipe through a linear motion, thereby facilitating the clamping and fixing of one end of the pipe. When one end of the pipe is clamped and fixed, the other end is suspended, and the feeding chuck and the pipe form a cantilever structure. At this time, no matter what changes occur in the length of the pipe, as long as it is within the allowable clamping force range of the feeding chuck, it will not affect the subsequent processing process.
[0059] When there are length differences in the pipes during the feeding process, after the length of the pipes changes, the structure of the conveyor line allows the pipes to still be reliably transported by the conveyor line to the lifting and positioning mechanism. The distance between the fixed-side conveyor line and the moving-side conveyor line can be adjusted according to the length of the pipes, and after adjustment, the guide rail locking device is locked and fixed.
[0060] The working process of the equipment has a low impact on manual operation, hardly changing the existing manual operation process, and can also achieve a certain degree of automated processing through the processing program set in the robot.
[0061] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
