Description

Technical Field

[0001] The invention relates to the field of laser welding, in particular to a laser device for automatic straight seam butt welding. Background Art

[0002] In modern industrial manufacturing, welding technology is widely used in many fields such as machinery, aviation, automobiles, and ships. In particular, straight butt welding, as a common welding method, plays an important role in the processing of workpieces such as pipes and plates. However, traditional welding equipment still has many shortcomings in terms of automation level, welding accuracy, stability, and adaptability, which limits its application in the field of high-precision welding.

[0003] Traditional welding equipment usually relies on manual operation, and the positioning, clamping, and movement of workpieces all require manual intervention. This mode of operation not only requires high skills from the operator, but is also prone to unstable welding accuracy due to human errors, especially when high-precision butt welding is required. Manual operation is inefficient, workpiece positioning is difficult to be accurate, welding results are poor, and the rework rate is high. In addition, traditional equipment has poor adaptability to workpieces of different sizes and shapes, and requires frequent replacement of fixtures or manual adjustments, which affects production efficiency.

[0004] During the welding process, the fixation and stability of the workpiece directly affect the welding quality. Traditional workpiece clamping devices usually use simple mechanical clamps, which cannot automatically adjust the clamping force according to the specific size and shape of the workpiece, causing the workpiece to loosen or be overstressed during welding, thus affecting the quality of the weld. In addition, if the heat generated during welding is not effectively removed, the equipment may overheat, which in turn affects the welding quality and the service life of the equipment. Traditional heat dissipation measures are often simple in design and cannot fully cope with long-term high-intensity welding work.

[0005] To solve these problems, automated welding equipment has gradually appeared on the market, which has improved the automation of the welding process to a certain extent and reduced the burden on operators. However, most of the existing automated equipment still has limitations in structural design, such as insufficient multi-axis movement accuracy, low intelligence level of clamping devices, limited ability to adapt to different workpiece sizes, and imperfect heat dissipation systems. With the rapid development of industrial automation and precision manufacturing technology, the market demand for high-precision and high-efficiency automated welding equipment is increasing.

[0026] Preferably, the refrigeration box is connected to the interior of the welding equipment through a circulation pipe, and heat-absorbing fins and heat-dissipating holes are provided in the refrigeration box for cooling the heat generated during the welding process.

[0027] Working principle: First of all, the chassis is the main supporting structure of the equipment. The top of the chassis is equipped with an observation window so that the operator can monitor the welding process in real time, and the support frame at the bottom provides stable structural support to prevent the equipment from vibrating during operation. The multi-axis moving mechanism of the equipment consists of X-axis linear guide rails, Y-axis linear guide rails and Z-axis linear guide rails, which work together to guide the laser welding head to move precisely in three directions. The X-axis guide rail is located above the support table, allowing the welding head to move horizontally; the Y-axis guide rail is installed vertically to control the displacement of the welding head in the up and down directions; the Z-axis guide rail is located on the Y-axis guide rail to achieve forward and backward movement. This three-dimensional movement ensures that the laser welding head can reach every welding point of the workpiece and complete the straight seam welding operation with precise control. The laser welding head is the core welding element of the equipment. It is connected to the multi-axis moving mechanism through a moving seat installed on the Z-axis guide rail. The laser welding head melts the contact surface of the workpiece through a high-energy laser beam to achieve butt welding. The three-axis movement of the moving seat enables the welding head to be adjusted according to the different positions of the workpiece to ensure the precise positioning of each welding point. The system's autofocus function can be adjusted according to the thickness and material of the workpiece to ensure the consistency and high quality of the welding process. The workpiece is fixed on the mobile table, which is mounted on the support table through an electric slide rail and can move along the X-axis direction to adjust the position of the workpiece. The function of the electric slide rail is to ensure that the mobile table can slide smoothly during the welding process and ensure the accurate positioning of the workpiece during the welding process. A second receiving seat is also provided under the mobile table to keep the workpiece stable through a sliding device. The clamping mechanism equipped with the equipment is used to firmly fix the workpiece to be welded to ensure that the workpiece remains stable during the welding process. The clamping mechanism includes a symmetrically arranged clamping plate 1 and a clamping plate 2, which are connected to the arc-shaped outer shell through a rotating shaft to form a hinged structure, so that the clamping plate can adjust the clamping force according to the size and position of the workpiece. A soft slide plate is installed on the inner side of the clamping plate to protect the surface of the workpiece from damage by the clamping force. The hydraulic push rod is connected to the clamping assembly to control the lifting and lowering of the clamping mechanism. The height of the clamping assembly is adjusted through the hydraulic system to adapt to workpieces of different heights. This ensures that the workpiece will not be affected by vibration or instability during the welding process. To further enhance the clamping capacity, the equipment is equipped with elastic adjustment, including spring one and spring two, which are respectively installed on the outer surface of the sliding column and the connecting column of the clamping plate. The spring device can automatically adjust the clamping force according to the size change of the workpiece to ensure that the clamping force is moderate during welding and prevent the clamping from being too loose or too tight. The moving assembly adjusts the spacing of the clamping mechanism through a double-headed motor and a threaded rod. The double-headed motor drives the moving block to move axially along the threaded rod through the threaded rod, thereby changing the distance between the clamping assemblies to adapt to workpieces of different widths and ensure the stable clamping of the workpiece during welding. To ensure the long-term operation of the equipment, the heat and smoke generated during the welding process are discharged through the fan located on the top of the chassis to maintain the temperature and air circulation inside the equipment.The refrigeration box is connected to the inside of the welding equipment through a circulation pipe, and uses heat-absorbing fins and heat dissipation holes to absorb and dissipate heat to prevent the equipment from overheating due to long-term welding.

[0028] The present invention provides a laser device for straight seam automatic butt welding. It has the following beneficial effects:

[0029] 1. The present invention realizes precise movement in the three directions of X, Y and Z through a multi-axis moving mechanism. The laser welding head can be precisely adjusted according to the position of the workpiece, ensuring high-precision operation during the welding process. It is particularly suitable for butt welding scenarios, and can effectively improve the straightness and accuracy of the weld, and reduce errors and rework rates.

[0030] 2. The clamping mechanism of the present invention can automatically adjust the clamping force according to the shape and size of the workpiece through the symmetrically arranged clamping plate 1 and clamping plate 2, combined with the elastic adjustment device and the hydraulic push rod, to ensure that the workpiece is stable during the welding process. The soft slide stretching improves the adaptability of the clamping plate and further ensures the integrity and aesthetics of the workpiece.

[0031] 3. The present invention is equipped with multiple heat dissipation and refrigeration measures such as fans, refrigeration boxes and honeycomb nets, which can effectively discharge heat during the welding process and ensure the stability and safety of the equipment during long-term operation. The refrigeration system can effectively cool the core components of the welding equipment through the cooperation of the circulation pipe and the heat-absorbing fins to prevent overheating from affecting the welding quality.

[0043] The following will be combined with the drawings in the embodiments 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.

[0044] Please see attached Figure 1 -Attached Fig.10 The embodiment of the present invention provides a laser device for straight seam automatic butt welding, comprising:

[0045] In this embodiment, the main body of the equipment is a chassis 1, which not only provides the overall support structure of the equipment, but also plays a role of protection and isolation. The internal structure of the chassis is reasonably designed, and a support table 4 for supporting other key components is installed. The support table is mainly used to carry the core components of the welding operation, such as a multi-axis moving mechanism, a laser welding head, etc. At the same time, a transparent observation window 2 is designed on the front of the chassis, which not only facilitates the operator to clearly observe the progress of the internal welding, but also ensures that the operator can adjust the position of the workpiece and the operating parameters of the equipment at any time during the welding process. The external structure of the chassis is reinforced by a support frame 3. The function of the support frame is to firmly fix the chassis on the work surface to avoid workpiece displacement or welding errors caused by vibrations generated by the equipment during welding. A stable support structure helps to ensure the overall smooth operation of the equipment and improve the accuracy and quality of welding.

[0046] During the operation of the equipment, the operator can monitor the entire welding operation process in real time through the observation window 2, and adjust and optimize the welding parameters in time. This can not only improve the efficiency of welding, but also avoid possible welding defects. The setting of the observation window also improves the safety of operation. When the operator does not need to directly contact the equipment, it can effectively monitor and reduce the danger of equipment operation.

[0047] In this embodiment, the welding accuracy of the equipment is achieved through a multi-axis moving mechanism. The core components of the multi-axis moving mechanism include an X-axis linear guide 5, a Y-axis linear guide 6, and a Z-axis linear guide 7. Among them, the X-axis linear guide 5 is installed on the surface of the support table 4 and is fixed, which provides basic support for the movement of the welding head in the horizontal direction. The Y-axis linear guide 6 is installed above the X-axis linear guide by sliding, and can move laterally along the X-axis, thereby providing vertical movement control for the equipment in the Y-axis direction. The Z-axis linear guide 7 is installed on the upper part of the Y-axis guide, and can slide to achieve movement in the front and rear directions, that is, the Z-axis direction. Therefore, the three guides cooperate with each other, and the laser welding head 9 is realized through sliding motion. All-round movement in the three dimensions of X, Y, and Z. This design can ensure that the equipment has a high degree of flexibility and freedom during the welding process, so that the welding head can be accurately adjusted to each point that needs to be welded according to different workpiece positions and welding requirements.

[0048] Through three-axis movement, the laser welding head 9 can not only move accurately in the horizontal plane, but also adjust the position in the vertical direction, while realizing the positioning adjustment in the front and rear directions. This three-dimensional mobile design not only improves the welding accuracy of the equipment, but also enhances its adaptability when processing complex welding workpieces. For example, when the shape of the workpiece is complex or requires welding operations in multiple different positions, the system can respond flexibly and complete the docking and stitching of different welding points by automatically adjusting the position of the welding head 9. At the same time, the precise control of the three-axis linkage can ensure the high precision of each welding point, achieve a smooth welding path, improve the quality of the weld, and avoid errors caused by manual adjustment.

[0049] In the specific operation process, the welding head is fixedly connected through the moving seat 8 on the Z-axis linear guide 7, so that the welding head can move accurately in the front and back direction along the Z-axis guide. The laser welding head 9, as the core welding element, melts the contact surface of the workpiece by emitting a high-energy laser beam to perform precise welding. The welding head is combined with the guide system, and the position of the welding head in three-dimensional space can be freely adjusted, thereby achieving precise welding of different positions of the workpiece.

[0050] In this embodiment, the laser welding head 9 is the core welding unit of the equipment, which melts the contact surface of the workpiece through a high-energy laser beam to achieve straight butt welding. The laser welding head is connected to the multi-axis moving mechanism through a moving seat 8 installed on the Z-axis linear guide 7. The moving seat enables the welding head to be accurately moved to different welding positions according to the control of the three-axis guide. During the welding process, the laser beam of the welding head is automatically focused according to the material and thickness of the workpiece to ensure the consistency of the welding effect and ensure high-quality welds.

[0051] In this embodiment, the mobile table 10 is used to carry the workpiece to be welded, and the mobile table is connected in the chassis by sliding. The mobile table is connected to the electric slide rail 16 and can move smoothly along the X-axis direction to ensure that the workpiece can be adjusted in position as the welding head moves during the welding process to ensure the accurate positioning of the workpiece. The electric slide rail is installed under the mobile table and can provide power for the mobile table to slide smoothly. In addition, the receiving seat 2 15 is fixedly connected to the lower surface of the mobile table, and the receiving seat slides on the electric slide rail, which further ensures the stable positioning of the workpiece during welding.

[0052] In this embodiment, in order to ensure the stability of the workpiece during the welding process, the equipment is equipped with a clamping mechanism, which is installed on the mobile table 10. The clamping mechanism includes a symmetrically arranged clamping plate 1 30 and a clamping plate 2 31, both of which are hingedly connected to the arc-shaped outer shell 23 through a rotating shaft 29. Through the rotation of the rotating shaft, the clamping plate can adjust its clamping force according to the size of the workpiece to ensure that the workpiece is firmly clamped. On the inner side of the clamping plate, a soft slide 32 is installed, one end of the slide is fixed on the clamping plate 1 30, and the other end can slide inside the clamping plate 2 31, thereby providing buffer protection when the workpiece is clamped to prevent excessive clamping force from causing damage to the workpiece surface.

[0053] In this embodiment, the height adjustment of the clamping mechanism is controlled by a hydraulic push rod 17. The output end of the hydraulic push rod is connected to the clamping assembly, and the lifting and lowering of the clamping assembly is controlled by the hydraulic system to adapt to workpieces of different heights. The hydraulic push rod ensures that the workpiece is kept at a suitable height during the welding process to avoid a decrease in welding accuracy due to improper height.

[0054] In this embodiment, the device is also equipped with an elastic adjustment device for automatically adjusting the clamping force according to the size and shape of the workpiece. The elastic adjustment device is composed of a spring 1 25 and a spring 28, which are respectively installed on the outer surface of the sliding column 24 and the connecting column 27**. Through the elastic adjustment of the spring, the clamping mechanism can automatically adapt to workpieces of different shapes to ensure the stability of the clamping, and the workpiece will not be damaged due to excessive clamping force, nor will the workpiece be loosened due to insufficient force.

[0055] In this embodiment, the moving assembly of the device is used to adjust the spacing between the clamping assemblies to adapt to workpieces of different widths. The moving assembly is driven by a double-headed motor 19, which drives the threaded rod 20 to rotate by meshing with the threaded rod. The threaded rod is threadedly connected to the moving block 21, and the moving block moves along the threaded rod to drive the support rod 22 of the clamping assembly to adjust horizontally, thereby changing the spacing of the clamping plates. Through the moving assembly, the device can adapt to workpieces of different widths, ensuring that the workpiece remains stable during the welding process.

[0056] In this embodiment, in order to ensure the temperature control of the device during long-term operation, a fan 33 is installed on the top of the chassis of the device to exhaust the smoke and heat generated during the welding process and maintain air circulation inside the device. In addition, the device is also equipped with a refrigeration system, which is cooled by a refrigeration box 34 and a circulation pipe 36. The refrigeration box is provided with heat-absorbing fins 38 and heat-dissipating holes 37. The heat-absorbing fins are used to absorb excess heat during the welding process, and the heat-dissipating holes dissipate heat through air circulation to prevent the device from overheating due to long-term operation. The refrigeration system is connected to the inside of the device through a circulation pump 39, which pushes the refrigerant to flow in the circulation pipe to ensure that the device maintains a suitable operating temperature during the welding process.

[0057] In this embodiment, in order to further enhance the heat dissipation effect, the device is equipped with a plurality of honeycomb nets 40 on the rear side of the chassis. These honeycomb nets enhance the heat dissipation performance of the device by increasing the air circulation. In addition, a metal shell 35 is installed at the rear of the honeycomb net, and a circulation pipe is arranged inside the metal shell to promote the coolant to circulate and cool through a circulation pump. This design further ensures that the device can work for a long time in a high temperature environment, and avoids the degradation of welding quality due to overheating of the device.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
