[0037] The following embodiments are described in conjunction with the accompanying drawings in this application.

[0038] like Figure 1 As shown, the present application provides a narrow gap high-speed self-melting welding device, comprising:

[0039] A base 1, a laser self-melting welding device 6 located on the base 1, and two symmetrically arranged welding mechanisms;

[0040] Each of the welding mechanisms comprises: a support assembly 2, which is slidably arranged on the base 1; a bending assembly 3, which is rotatably arranged on the support assembly 2; a clamp 4, which is fixed on the bending assembly 3, and a welding piece 5 is clamped on the clamp 4;

[0041] The laser self-melting welding device 6 includes a welding head, which faces the welding parts 5 and is used to weld the gap between the two welding parts 5 .

[0042] Specifically, exemplarily, the laser self-melting welding equipment 6 adopts an existing laser self-melting welding robot, and the specific model is not specifically limited in this application. The laser self-melting welding robot can achieve high-speed reciprocating movement. The exemplary laser self-melting welding robot includes a laser head, a cooling device and a laser control device. The laser head can achieve rapid reciprocating movement. The cooling device is located at the upper part of the laser head, and the laser generates laser transmission to the laser head. Exemplarily, the laser can be a solid laser, a gas laser, a liquid laser and a free electron laser type. Two welding mechanisms are used to control the welding angles of the two welded parts 5. And the two symmetrically arranged welding mechanisms can be slidably arranged on the base 1, which can adapt to welded parts 5 of different sizes. Each welding structure includes: a support assembly 2, a bending assembly 3 and a clamp 4, the support assembly 2 is slidably arranged on the base 1, and the bending assembly 3 is rotatably arranged on the support assembly 2; the clamp 4 is fixed on the bending assembly 3, so that the clamp 4 can achieve different angles of rotation when the bending assembly 3 rotates relative to the support assembly 2. The clamp 4 holds a weldment 5, and the laser self-melting welding device 6 includes a welding head, which faces the weldment 5 and is used to weld the gap between the two weldments 5. Driven by the clamp 4, the welding of the weldment 5 at different angles can be controlled, which can ensure that the welding is more firm and not easy to deform.

[0043] For example, the laser self-melting welding device 6 may include a laser source (welding head), a laser lens, a laser galvanometer (see Figure 8The reference numeral 7 shown is a laser lens, a laser galvanometer) and a scanning device. The laser source is used to generate a high-energy laser beam, and its wavelength and power can be selected according to specific requirements. The laser lens is further used to adjust and focus the laser beam so as to achieve the required power density during the welding process. The scanning device is further used to control the motion trajectory of the laser beam, such as realizing a reciprocating or scanning movement mode. Exemplarily, the optimal focus spot diameter of the laser beam is 1.2 mm, or the focus spot diameter will change with the folding speed of the welded part during the welding process and the sheet material properties of the welded part. Exemplarily, the control system will first identify the sheet material of the welded part, and determine the diameter of the focus spot according to the preset sheet material and the mapping relationship between the focus spot diameter. The laser self-melting welding device 6 corresponds to a control system, and the control system may include a controller and a group of sensors. The controller is used to control the movement and parameter settings of the laser device and the bending device. It can receive and process feedback signals from the sensor and make real-time adjustments as needed. The sensor is further used to monitor key parameters in the welding process, such as laser power, welding speed, temperature, etc. By monitoring and feedback control of these parameters, high-quality welding results can be achieved.

[0044] In some embodiments, Figure 2 , Figure 6 and Figure 7 As shown, the base 1 is provided with a driving assembly 12 for driving the welding mechanism to move, and the driving assembly 12 includes a driving motor and a bidirectional screw 13. The bidirectional screw 13 is rotatably arranged on the base 1, and one end of the bidirectional screw 13 is connected to the driving motor.

[0045] Specifically, exemplary, such as Figure 2 and Figure 6 As shown, a slide groove 11 is provided on the base 1, and the two support assemblies 2 move relatively along the length direction of the slide groove 11; a driving assembly 12 is provided in the slide groove 11, and the driving assembly 12 includes a driving motor and a bidirectional screw 13, and the bidirectional screw 13 is rotatably arranged in the slide groove 11, and one end of the bidirectional screw 13 passes through the base 1 and is connected to the driving motor. The driving motor drives the bidirectional screw 13 to rotate, and the rotation of the bidirectional screw 13 drives the two support assemblies 2 to move in opposite directions, so that the distance between the two support assemblies 2 can be adjusted, so that the distance between the welding structures can be adjusted to accommodate weldments 5 of different sizes. Exemplarily, the weldment 5 is a stainless steel plate. The weldment 5 can also be other metal weldments 5, and the stainless steel plate is taken as an example in this application.

[0046] For example, Figure 7As shown, two symmetrical and vertically arranged mounting seats 14 are provided on the base 1, and the bidirectional screw 13 is rotatably arranged on the mounting seats 14. The bidirectional screw 13 penetrates the mounting seats 14 and is connected to the driving motor. The driving motor drives the bidirectional screw 13 to rotate, and the rotation of the bidirectional screw 13 drives the two support assemblies 2 to move in opposite directions, so that the distance between the two support assemblies 2 can be adjusted, so that the distance between the welding structures can be adjusted to adapt to different sizes of welded parts 5. Exemplarily, the welded part 5 is a stainless steel plate. The welded part 5 can also be other metal welded parts 5, and the stainless steel plate is taken as an example in this application.

[0047] In some embodiments, Figure 2 As shown, the support assembly 2 includes a movable plate 21 and at least one support seat 22, a slider 211 is provided at the bottom of the movable plate 21, the slider 211 is sleeved on the bidirectional screw 13, and the support seat 22 is arranged on the top of the movable plate 21; a mounting groove 221 is provided on the support seat 22, and the bending assembly 3 is rotatably arranged in the mounting groove 221.

[0048] Specifically, Figure 2 As shown, illustratively, the support assembly 2 includes a support plate 31 and two support seats 22, and the two support seats 22 are arranged in an array on the support plate 31, so that the two support seats 22 can be installed with two bending assemblies 3, and larger welded parts 5 can be welded. A slider 211 is provided at the bottom of the movable plate 21, and the sliders 211 at the bottom of the two movable plates 21 are respectively sleeved on the threads of the bidirectional screw 13 in different directions, so that when the bidirectional screw 13 rotates, the two movable plates 21 can drive the support seats 22 to move in opposite directions, so that the distance between the two bending assemblies 3 can be controlled to adapt to welding of welded parts 5 of different sizes.

[0049] In some embodiments, Figure 2 As shown, the bending assembly 3 includes a support plate 31, a rotating shaft 32 and a lifting cylinder 33. The support plate 31 is rotatably set in the mounting groove 221, the rotating shaft 32 is rotatably set at one end of the support plate 31, the lifting cylinder 33 is rotatably set on the movable plate 21, and the rotating shaft 32 is connected to the lever end of the lifting cylinder 33.

[0050] Specifically, Figure 2As shown, exemplarily, the bending assembly 3 includes two, each bending assembly 3 is respectively arranged on the corresponding support seat 22, and the two bending assemblies 3 share a rotating shaft 32 and a cylinder, that is, two adjacent supporting plates 31 are respectively rotatably connected to the two ends of a rotating shaft 32, and the cylinder is arranged in the middle of the rotating shaft 32, which can drive the two supporting plates 31 to rotate. When the cylinder rises, the supporting plate 31 can be controlled to rotate 0° to 70° in the mounting groove 221, so that the welding piece 5 clamped by the clamp 4 can be controlled to rotate 0° to 70°, so that when the laser self-melting welding device 6 performs reciprocating motion during welding, the cylinder gradually rises, and the two welding pieces 5 are gradually rotated until the two welding pieces 5 are parallel, and the laser self-melting welding device 6 welds the gap between the two welding pieces 5. When the cylinder rises, the support plate 31 can be controlled to rotate 0° to -70° in the installation groove 221. At this time, the welding head of the laser self-melting welding equipment 6 can be extended under the two welding parts 5. The laser self-melting welding equipment 6 makes reciprocating motion during welding, and the cylinder gradually descends to gradually rotate the two welding parts 5 until the two welding parts 5 are parallel. The laser self-melting welding equipment 6 welds the gap between the two welding parts 5.

[0051] Exemplarily, the bending assembly 3 includes a support plate 31 and a motor. The support plate 31 is rotatably disposed in the mounting groove 221 . The motor is disposed on the side wall of the support seat 22 . The motor penetrates the support seat 22 and is connected to the support plate 31 .

[0052] Specifically, the motor can drive the support plate 31 to rotate, thereby changing the rotation angle of the support plate 31. Specifically, the motor can drive the support plate 31 to rotate 70° to 70° in the mounting groove 221. The specific welding method is consistent with the welding method in the above embodiment, and will not be described in detail in this embodiment, except that the cylinder control method is changed to the motor drive method.

[0053] In some embodiments, Figure 3 As shown, the clamp 4 includes a chuck 41 and a clamping assembly 42 arranged on the chuck 41, and the clamping assembly 42 includes a rotating rod 421 and a clamping plate 422. The rotating rod 421 rotates and passes through the side wall of the chuck 41 and is connected to the clamping plate 422 located in the chuck 41, and the welding part 5 is clamped on the clamping plate 422 and the inner wall of the chuck 41.

[0054] Specifically, the chuck 41 is in a U-shaped shape, and the rotating rod 421 is rotatably arranged on the top of the chuck 41. The rotating rod 421 is a screw, with a rotating head at one end and the other end passing through the side wall of the chuck 41 and connected to the clamping plate 422. The bottom of the clamping plate 422 may be provided with an anti-skid pad, so that when clamping the weldment 5, the anti-skid pad can fit closely with the weldment 5 and can stably clamp. By adjusting the rotating rod 421, the clamping plate 422 can clamp the weldment 5.

[0055] In some embodiments, Figure 3 As shown, two slots 222 are provided on the side wall of the support base 22 , and the slots 222 are communicated with the mounting slot 221 , and a plug 223 is provided in one of the slots 222 .

[0056] Specifically, two slots 222 are provided on the side wall of the support seat 22, which can control the rotation angle limit of the support plate 31 provided in the mounting slot 221. For example, when the plug 223 is inserted into the slot 222 adjacent to another set of welding mechanisms, the support plate 31 can only rotate 0° to 70°. When the plug 223 is inserted into the slot 222 away from another set of welding mechanisms, the support plate 31 can only rotate 0° to -70°. In this way, stable welding of the weldment 5 can be ensured.

[0057] In some embodiments, Figure 4 and Figure 5 As shown, the rotation angle range of the support plate 31 in the mounting groove 221 is: 70° to -70°.

[0058] Specifically, Figure 4 It is shown in FIG. 2 that the support plate 31 can rotate within the mounting groove 221 within an angle range of 0° to 70°. At this time, the laser source of the laser self-melting welding device 6 is located above the weldment 5 for welding. Figure 5 It is shown that the support plate 31 can rotate within the installation groove 221 within an angle range of 0° to -70°. At this time, the laser source of the laser self-melting welding device 6 is located below the weldment 5 for welding.

[0059] In some embodiments, Figure 8 As shown, based on the above embodiment, two groups of support plates 8 are symmetrically arranged on the base 1, and a guide shaft 10 and a roller 9 are provided between each group of support plates 8. The roller 9 makes an arc motion on the support plate, and the welding part is arranged between the roller 9 and the guide shaft 10.

[0060] Specifically, the rollers 9 can be controlled by the cylinder to make an arc motion on the support plate (as shown in the running directions of the two arrows in the figure), and the two rollers 9 gradually move closer to each other, so that the angle between the two welded parts can be gradually reduced to make the two welded parts parallel. That is, the two rollers gradually press the two welded parts to gradually reduce the angle between the two welded parts.

[0061] In some embodiments, a preheater is provided on the base, and a preheating end of the preheater faces the welding end of the welded part.

[0062] Exemplarily, the preheater can be a heating wire plus a fan to preheat the welded parts to be welded, which is more helpful to improve the welding effect of the welded parts.

[0063] In some embodiments, during the welding process of the welded parts, filler wire and filler powder can be used to assist in narrow gap laser self-melting welding. The welding material is suitable for materials that are easy to oxidize and form pores.

[0064] The specific welding process in this application is as follows:

[0065] First, clamp the two stainless steel plates on the corresponding clamps 4 to ensure accurate positioning, and then rotate the rotating rod 421 to clamp the stainless steel plates with the clamp plate 422. After the fixing is completed, adjust the angle between the two stainless steel plates by controlling the lifting range of the cylinder to keep the angle at 50°-70°. For example, taking the lifting of the lifting cylinder 33 as an example, the lifting cylinder 33 pushes the support plate 31 to gradually flatten when it rises, and its driving speed is controlled at a speed of 1° per second. Before welding, adjust the parameters of the laser self-melting welding equipment 6, and control the laser self-melting welding equipment 6 to reciprocate for welding. During the welding process, the laser beam of the laser self-melting welding equipment 6 moves back and forth on the stainless steel plate along the welding area. Ensure that the motion trajectory of the laser beam matches the desired weld shape and maintain a constant moving speed.

[0066] The parameters of the laser self-melting welding equipment 6 include: controlling the welding power to be between 2500 and 3000 W, the welding speed to be 80-100 mm / s, the defocusing amount to be 0-1 mm, the gas flow rate to be 25-30 L / min, and turning on the laser galvanometer system to achieve high-speed reciprocating oscillation of the laser.

[0067] Furthermore, the lifting cylinder 33 can be automatically controlled according to the welding angle of the stainless steel plate, which is not specifically limited in the present application, and 0° (ie, two welded parts are parallel) is taken as an example.

[0068] Based on the same inventive concept, Fig. 9 As shown, the present application also provides a narrow gap self-fluxing welding method, comprising:

[0069] Clamp two welded parts 5 to be welded on symmetrically arranged clamps 4 respectively, and control the rotation angle of the bending assembly 3 to drive the clamps 4 to rotate, so that the angle of the two welded parts 5 is within a preset angle range;

[0070] Controlling the laser self-melting welding equipment to weld the two welding parts 5 according to preset welding parameters;

[0071] During the welding process, the bending assembly 3 is controlled to bend at 1° per second until the two welded parts 5 are parallel and have no gap.

[0072] Specifically, first clamp the two stainless steel plates on the corresponding clamps 4 to ensure accurate positioning, and then rotate the rotating rod 421 to clamp the stainless steel plates with the clamp 422. After the fixing is completed, adjust the angle between the two stainless steel plates by controlling the lifting range of the cylinder to keep the angle at 50°-70°. For example, taking the lifting of the lifting cylinder 33 as an example, the lifting cylinder 33 pushes the support plate 31 to gradually flatten when it rises, and its driving speed is controlled at a speed of 1° per second. Before welding, adjust the parameters of the laser self-melting welding equipment 6, and control the laser self-melting welding equipment 6 to reciprocate for welding during welding. During the welding process, the laser beam of the laser self-melting welding equipment 6 moves back and forth on the stainless steel plate along the welding area. Ensure that the motion trajectory of the laser beam matches the desired weld shape and maintain a constant moving speed.

[0073] The parameters of the laser self-melting welding equipment 6 include: controlling the welding power to be between 2500 and 3000 W, the welding speed to be 80-100 mm / s, the defocusing amount to be 0-1 mm, the gas flow rate to be 25-30 L / min, and turning on the laser galvanometer system to achieve high-speed reciprocating swing of the laser. The above welding method can achieve high-speed and high-quality welding results.

[0074] In some embodiments, the preset angle range is 50° to 70°. The rotation angle of the bending component 3 can be controlled according to the actual welding requirements, which is not specifically limited in this embodiment. The rotation angle range of the welded part in this application can be 70° to -70°; it is optimal to keep the angle at 50°-70° during welding.

[0075] In some embodiments, the preset welding parameters include: welding power of 2500W-3000W, welding speed of 80mm / S-100mm / S, defocus of 0mm-1mm, and gas flow of 25L / min-30L / min. By controlling the welding power of the laser self-melting welding device to 2500W-3000W, the welding speed to 80mm / S-100mm / S, the defocus of 0mm-1mm, and the gas flow of 25L / min-30L / min, the welding cost and welding time can be saved, and the quality of the welded stainless steel plate is better.

The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.
