Description

Technical Field

[0001] This invention belongs to the field of welding equipment technology, specifically a high-efficiency laser welding equipment for parts. Background Technology

[0002] Laser welding technology, with its significant advantages such as high energy density, small heat-affected zone, and minimal welding deformation, has become a key technology in precision manufacturing, particularly in the joining processes of high-value-added products such as new energy vehicle batteries, precision instruments, and aerospace structural components. As the manufacturing industry moves towards greater automation, intelligence, and flexibility, higher demands are being placed on the comprehensive performance of laser welding equipment: it must not only achieve high-quality and consistent welds, but also significantly increase production cycle time, reduce reliance on highly skilled operators, and ensure the safety and environmental friendliness of the operation process.

[0003] However, conventional laser welding equipment in the current technology still faces several bottlenecks in meeting such demands. First, when welding complex workpieces at multiple angles, traditional equipment relies heavily on manual labor or external positioners for repeated positioning and clamping. This process is time-consuming and labor-intensive, and is prone to weld misalignment due to secondary clamping errors, severely affecting efficiency and accuracy. At the same time, the high-intensity laser diffuse reflection and metal spatter generated during the welding process pose a potential safety threat to the operator, and external airflow can significantly affect the welding quality and interfere with process stability. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency laser welding device for parts in order to solve the above-mentioned problems, thereby solving the problems mentioned in the background art.

[0005] To address the above problems, the present invention provides a technical solution: A high-efficiency laser welding device for parts includes a body, a frame mounted on the body, a welding head mounted on the frame, a protective mechanism mounted on the frame, a support platform mounted inside the body via bearings, a bracket fixedly connected to the lower end of the support platform, a clamping mechanism mounted on the bracket, a support cylinder fixedly connected to the lower end of the support platform, a toothed ring fixedly connected to the outer side of the support cylinder, and a motor fixedly mounted at the lower end of the body.

[0006] Preferably, a gear is fixedly connected to the lower end of the motor shaft, and the gear meshes with a gear ring. By setting the gear, the gear ring is driven to rotate.

[0007] Preferably, the protective mechanism includes a support ring, which is fixedly connected to the outer side of the frame. A fixed cylinder is fixedly connected to the lower end of the support ring. A first protective plate is embedded inside the fixed cylinder. A sliding cylinder is slidably connected to the outer side of the fixed cylinder, and a second protective plate is fixedly connected to the inner side of the sliding cylinder. By using the combination of the fixed cylinder and the sliding cylinder, the sliding cylinder can be adjusted up and down according to the height of the workpiece, forming a semi-enclosed or fully enclosed protective space with the support table. Both the first and second protective plates are made of black transparent high-resistance resin. This structure effectively reduces strong laser reflection and metal spatter generated during welding, protects the operator's safety, prevents environmental pollution, reduces interference from external airflow and dust on the laser beam path, and improves process stability.

[0008] Preferably, a guide block is fixedly connected to the inner wall of the slide cylinder, and the guide block is slidably connected to the fixed cylinder. The guide block guides the movement of the slide cylinder.

[0009] Preferably, the clamping mechanism includes a mounting plate, with the mounting plate fixedly connected to the lower end of the support platform. A screw is mounted inside the mounting plate via a bearing, and a driven bevel gear is fixedly connected to the end of the screw. A motor is fixedly mounted on the inner bottom of the bracket. A sliding plate is slidably connected inside the support platform, and the sliding plate and the screw are movably connected. A pressure plate is slidably connected to the lower end of the support platform, and the pressure plate and the screw are connected by a thread. A guide rod is fixedly connected to the surface of the pressure plate, and the guide rod and the pressure plate are slidably connected. A compression spring is provided on the outer side of the guide rod. An insert rod is slidably connected inside the sliding plate, and a clamping plate is fixedly connected to the upper end of the insert rod. A V-groove is formed on one side surface of the clamping plate, and an anti-slip pad is adhered to the groove wall of the V-groove. The motor drives the support platform to rotate, thereby changing the position of the clamping mechanism. This allows for the welding of circumferential welds or welds in different positions, avoiding the tedious process of repeatedly positioning and clamping complex workpieces, and greatly improving welding efficiency. The motor drives the screw to rotate and cooperate with the pressure plate, causing the clamping plate on the slide plate to move due to the elasticity of the pressure spring. This allows for adaptive clamping of the workpiece, ensuring that the surfaces of the two workpieces remain in contact. By disengaging the insert rod and the slide plate, the clamping plate can change position. This allows for clamping of flat workpieces, and the V-groove can also clamp cylindrical workpieces of different diameters. The anti-slip pad increases friction and effectively prevents workpiece displacement caused by welding vibration, ensuring the absolute stability of the joint during the welding process, thereby improving the uniformity and consistency of the weld.

[0010] Preferably, a driving bevel gear is fixedly connected to the upper end of the motor shaft, and the driving bevel gear meshes with the driven bevel gear. By setting the driving bevel gear, the driven bevel gear is driven to rotate.

[0011] Preferably, one end of the compression spring is fixedly connected to the pressure plate, and the other end of the compression spring is fixedly connected to the slide plate. By setting the compression spring, the slide plate is elastically compressed.

[0012] Preferably, a protrusion is fixedly connected to the lower end of the clamping plate, and the protrusion is slidably connected to the support platform. The protrusion provides auxiliary support to the clamping plate.

[0013] The beneficial effects of this invention are as follows: This invention relates to a high-efficiency laser welding equipment for parts, which features easy adjustment of the workpiece angle and higher welding quality after clamping the workpiece. In specific use, compared with traditional high-efficiency laser welding equipment for parts, this high-efficiency laser welding equipment for parts has the following beneficial effects: First, the motor drives the support platform to rotate, thereby changing the position of the clamping mechanism. This allows for the welding of circumferential welds or welds in different positions, avoiding the tedious process of repeatedly positioning and clamping complex workpieces, and greatly improving welding efficiency. The motor drives the screw to rotate and cooperate with the pressure plate, causing the pressure plate to move the clamping plate on the slide plate through the elastic force of the compression spring. This can adaptively clamp the workpiece, ensuring that the surfaces of the two workpieces remain in contact. By disengaging the insertion rod and the slide plate, the clamping plate can change position. This allows for clamping of flat workpieces, and the V-groove can also clamp cylindrical workpieces of different diameters. The anti-slip pad increases friction, effectively preventing workpiece displacement caused by welding vibration, ensuring the absolute stability of the joint during the welding process, and thus improving the uniformity and consistency of the weld.

[0014] Secondly, by using a combination of a fixed cylinder and a sliding cylinder, the sliding cylinder can be adjusted up and down according to the height of the workpiece, forming a semi-enclosed or fully enclosed protective space with the support table. Furthermore, both the first and second protective plates are made of black transparent high-resistance resin. This structure can effectively reduce the strong laser reflection and metal spatter generated during welding, protect the safety of operators, prevent environmental pollution, and reduce the interference of external airflow and dust on the laser beam path, thereby improving process stability.

[0018] like Figure 1-7 As shown, the specific implementation adopts the following technical solution: Example: A high-efficiency laser welding device for parts includes a body 1, a frame 2 mounted on the body 1, a welding head 3 mounted on the frame 2, a protective mechanism 4 mounted on the frame 2, a support platform 5 mounted inside the body 1 via bearings, a bracket 6 fixedly connected to the lower end of the support platform 5, a clamping mechanism 7 mounted on the bracket 6, a support cylinder 8 fixedly connected to the lower end of the support platform 5, a gear ring 9 fixedly connected to the outer side of the support cylinder 8, a motor 10 fixedly mounted at the lower end of the body 1, a gear 11 fixedly connected to the lower end of the shaft of the motor 10, the gear 11 meshing with the gear ring 9, and driving the gear ring 9 to rotate by setting the gear 11.

[0019] The protective mechanism 4 includes a support ring 41, which is fixedly connected to the outer side of the frame 2. A fixed cylinder 42 is fixedly connected to the lower end of the support ring 41. A first protective plate 43 is embedded inside the fixed cylinder 42. A slide cylinder 44 is slidably connected to the outer side of the fixed cylinder 42. A guide block is fixedly connected to the inner wall of the slide cylinder 44. The guide block and the fixed cylinder 42 are slidably connected. The guide block guides the movement of the slide cylinder 44. A second protective plate 45 is fixedly connected to the inner side of the slide cylinder 44. By combining the fixed cylinder 42 and the slide cylinder 44, the slide cylinder 44 can be adjusted up and down according to the height of the workpiece, forming a semi-enclosed or fully enclosed protective space with the support table 5. The first protective plate 43 and the second protective plate 45 are both made of black transparent high-resistance resin. This structure can effectively reduce the strong laser reflection and metal spatter generated during welding, protect the safety of operators, prevent environmental pollution, reduce the interference of external airflow and dust on the laser beam path, and improve the stability of the process.

[0020] The clamping mechanism 7 includes a mounting plate 71. The lower end of the support platform 5 is fixedly connected to the mounting plate 71. A screw 72 is mounted inside the mounting plate 71 via bearings. A driven bevel gear 73 is fixedly connected to the end of the screw 72. A motor 74 is fixedly mounted on the inner bottom of the bracket 6. A driving bevel gear 75 is fixedly connected to the upper end of the shaft of the motor 74. The driving bevel gear 75 and the driven bevel gear 73 mesh. By setting the driving bevel gear 75, the driven bevel gear 73 is driven to rotate. A sliding plate 76 is slidably connected inside the support platform 5. The sliding plate 76 and the screw 72 are connected together. The support platform 5 is slidably connected to a pressure plate 77 at its lower end. The pressure plate 77 and the screw 72 are connected by threads. A guide rod 78 is fixedly connected to the surface of the pressure plate 77. The guide rod 78 and the pressure plate 77 are slidably connected. A compression spring 79 is provided on the outer side of the guide rod 78. One end of the compression spring 79 is fixedly connected to the pressure plate 77, and the other end of the compression spring 79 is fixedly connected to the slide plate 76. By setting the compression spring 79, the slide plate 76 is elastically compressed. An insert rod 710 is slidably connected inside the slide plate 76. A clamping plate 711 is fixedly connected to the upper end of the insert rod 710. The lower end of the clamping plate 711... A protrusion 712 is fixedly connected to the end, and the protrusion 712 and the support platform 5 are slidably connected. By setting the protrusion 712, the clamping plate 711 is provided with auxiliary support. A V-groove is opened on one side surface of the clamping plate 711, and an anti-slip pad 713 is adhered to the groove wall. The support platform 5 is driven to rotate by the motor 10, thereby changing the position of the clamping mechanism 7. This allows for the welding of circumferential welds or welds in different positions, avoiding the tedious process of repeatedly positioning and clamping complex workpieces, and greatly improving welding efficiency. The screw 72 is driven to rotate by the motor 74 and cooperates with the pressure plate 77 to make... The pressure plate 77 moves the clamping plate 711 on the slide plate 76 through the elastic force of the compression spring 79, which can adaptively press the workpiece, so that the surfaces of the two workpieces can remain in contact. By disengaging the insert rod 710 and the slide plate 76, the clamping plate 711 can change position. It can clamp the workpiece plane, and it can also clamp cylindrical workpieces of different diameters through the V-groove. The anti-slip pad 713 increases the friction and effectively prevents the workpiece from shifting due to welding vibration, ensuring the absolute stability of the joint during the welding process, thereby improving the uniformity and consistency of the weld.

[0021] The invention is used as follows: During use, the operator places the workpiece to be welded on the support table 5, positioning it between the clamping plates 711. Using the workpiece side shape adjustment device, the operator manually moves the clamping plates 711 upwards, causing the clamping plates 711 to separate the insert rod 710 and the sliding plate 76. Then, the clamping plate 711, with one side meeting the clamping conditions facing the workpiece, is inserted into the sliding plate 76. Using the weld direction adjustment device, the operator starts the motor 10, which drives the gear 11 to rotate. The gear 11 meshes with the gear ring 9 fixed on the support cylinder 8, thereby driving the entire support table 5 to rotate smoothly and precisely around its bearing axis. This ensures that the weld angle is consistent with the movement direction of the machine head on the frame 2. Then, the operator starts the motor 74, whose shaft drives the active bevel gear 75 to rotate, which in turn drives the driven bevel gear 73 meshing with the active bevel gear 75. The driven bevel gear 73 drives the screw 72 to rotate. The rotation of the screw 72 causes a threaded movement with the pressure plate 77, causing the pressure plate 77 to move along... The guide rod 78 slides downward, the pressure plate 77 presses down the compression spring 79, and the elastic force of the compression spring 79 is evenly transmitted to the insertion rod 710 through the sliding plate 76, thereby causing the clamping plate 711 to move towards the center of the workpiece. The surface of the clamping plate 711 can adaptively fit the outer side of the workpiece. The component of the frame 2 that mounts the welding head 3 moves down, the frame 2 drives the support ring 41 to move, the support ring 41 drives the fixed cylinder 42 to move down, thereby causing the sliding cylinder 44 to move down and contact the workpiece. The guide block on the inner wall of the sliding cylinder 44 slides along the outer side of the fixed cylinder 42, forming a semi-closed or nearly closed space that surrounds the area below the welding head 3. The first protective plate 43 and the second protective plate 45 are both made of black transparent high-temperature resistant resin. This material can effectively absorb and block most of the harmful laser reflections and strong light, preventing eye and skin damage to operators, and allows operators to clearly observe the welding pool and process. At the same time, this protective space can effectively isolate the spatter, smoke and dust generated by welding, protect the internal optical components of the equipment from contamination, reduce external airflow disturbances, and improve the stability of the welding process.
