Description

Technical Field

[0001] This invention relates to the field of part positioning and welding technology, and in particular to a laser welding device that facilitates the positioning of parts. Background Technology

[0002] Component welding is a core process for achieving component forming and functional integration. It is widely used in key fields such as high-end equipment manufacturing. With the acceleration of industrial upgrading, downstream industries have put forward higher requirements for the precision, consistency and production efficiency of welded parts. As the core factor that determines the welding quality, the positioning accuracy of parts ensures that the parts do not deviate or loosen during the laser welding process.

[0003] Application number CN202411918716.X discloses a metal parts processing positioning and welding device, belonging to the field of metal parts welding technology. This metal parts processing positioning and welding device includes a processing table, a placement seat, a welding mechanism, and a positioning mechanism. The placement seat is rotatably mounted on the surface of the processing table for placing parts. The welding mechanism is mounted on the surface of the processing table and includes a transverse frame, a positioning block, and a support arm. The transverse frame is slidably mounted on the surface of the processing table, and welding heads are symmetrically fixedly mounted on the surface of the transverse frame. This invention, by setting up a welding mechanism, places the lower part along the side wall of the positioning block on the surface of the placement seat. A motor drives the welding head to move towards the surface of the part, and a second driving block drives the first driving block to move downwards, thereby driving the first connecting rod and the worm gear to move downwards synchronously, thus driving the worm wheel and the double-acting screw to rotate. This drives the second threaded blocks on both sides to move the clamping blocks closer together, clamping and fixing the part on the surface of the placement seat, making it convenient to use.

[0004] Application number CN202111071710.X discloses a repair welding device with positioning function and its usage method, including a non-powered pressurized clamping device, a closed hydraulic self-driven tensioning device, a main clamping frame, and welding execution components. This invention belongs to the technical field of manual welding devices, specifically referring to a repair welding device with positioning function and its usage method. This invention utilizes the heat generated during welding to soften the rubber pad and increase the pre-tightening force simultaneously, causing the rubber pad to deform in accordance with the surface of the weldment, thereby improving the clamping firmness. Through the self-driven tensioning structure, heat radiation during welding tightens the objects on both sides of the current welding area, increasing the pressure at the molten pool, thus improving the weld's firmness. Combined with the frame and handheld welding torch, it overcomes the technical bias of requiring disassembly of parts before welding repair, effectively solving the problem of easy displacement during non-disassembly welding in current engineering machinery welding.

[0005] Based on the above patent search and understanding of the application of existing parts welding equipment:

[0006] Traditional welding devices often have fixed or single-dimensional adjustment components, such as up and down or left and right. They cannot quickly and accurately adapt to the position in three-dimensional space (front, back, left, right, up and down) according to the different welding positions of the parts. This results in low welding efficiency and welding defects caused by adjustment errors.

[0007] After welding is completed, the existing equipment requires manual loosening and removal of the workpiece, which not only increases the labor intensity of the operators, but also poses a risk of workpiece damage due to manual handling.

[0008] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a laser welding device that facilitates the positioning of parts, in order to achieve a more practical purpose. Summary of the Invention

[0009] To address the aforementioned technical problems, this invention provides a laser welding device that facilitates the positioning of parts. This addresses the limitations of existing devices where welding components are mostly fixed or can only achieve single-dimensional adjustment, such as up / down or left / right. These devices cannot quickly and accurately adapt to different welding positions in three-dimensional space (front / back, left / right, up / down), resulting in low welding efficiency and susceptibility to welding defects due to adjustment errors. Furthermore, existing devices require manual removal of the workpiece after welding, increasing the operator's workload and posing a risk of workpiece damage due to manual handling.

[0010] This invention provides a laser welding device for easy positioning of parts, specifically comprising: a base; a base fixedly installed at the top center of the base; a guide frame fixedly installed at the top front of the base; a guide groove opened at the top center of the guide frame; a limiting groove opened at the front of the guide groove; a cylinder B fixedly connected to the rear of the guide frame; a push plate provided at the front of the cylinder B; the push plate located in the guide groove of the guide frame; a cylinder C fixedly connected to the left front of the guide frame; a blocking member provided at the right side of the cylinder C; the blocking member located in the limiting groove of the guide frame; a through groove opened at the top right side of the blocking member; the bottom of the through groove of the blocking member being flush with the bottom of the guide groove of the guide frame; a cylinder D fixedly installed on the top left and right sides of the base, the two cylinders D being symmetrically distributed on the left and right sides of the guide frame, and the two cylinders D being located on the rear sides of the limiting groove of the guide frame; and a clamping plate provided on the inner side of each cylinder D.

[0011] Furthermore, a side frame is provided at the rear position of both the left and right sides of the base. The base is located at the top rear position of the advance frame. The lower positions of both the left and right sides of the advance frame are slidably connected to the inside of a side frame. A threaded hole is provided at the lower left position of the advance frame.

[0012] Furthermore, a motor A is fixedly installed at the front end of the left side frame of the base. The shaft of motor A is threaded, and the shaft of motor A is located in the threaded hole at the lower left of the advancing frame.

[0013] Furthermore, a motor B is fixedly installed on the top left side of the advancing frame. The shaft of the motor B is threaded. A transverse adjustment frame slides laterally on the top of the advancing frame. A threaded hole is opened on the side of the transverse adjustment frame, and the shaft of the motor B is located in the threaded hole of the transverse adjustment frame.

[0014] Furthermore, a motor C is fixedly installed at the top of the lateral adjustment frame, the shaft of the motor C is threaded, the front end of the lateral adjustment frame is slidably connected to the upper rear end of the lifting frame, a threaded hole is opened at the upper rear end of the lifting frame, and the shaft of the motor C is located in the threaded hole of the lifting frame.

[0015] Furthermore, a cylinder A is fixedly installed at the upper front end of the lifting frame, and a laser welder is installed at the bottom of the cylinder A.

[0016] Furthermore, the base has a side frame on both sides of the top rear side, and a side clamp is slidably connected to the top of each side frame. A threaded hole is opened at the lower middle position of each side clamp. A screw is rotatably connected to the upper inside of the side frame. The screw is located in the threaded hole of the side clamp. A scale value is set at the top of the side frame.

[0017] Furthermore, a workpiece is placed in the guide groove of the guide frame, and the workpiece is located between the two clamping plates. When the cylinder C is in the extended state, the left rear end of the blocking member is in contact with the front end of the workpiece. When the cylinder C is in the retracted state, the through groove of the blocking member is flush with the guide groove of the guide frame.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The workpiece is positioned in the front-to-back direction by cylinder B and the push plate, and laterally by cylinder D and the clamping plate. Combined with the lateral frame, screw, and lateral fixture's oblique lateral positioning structure, a three-dimensional positioning system is formed, covering the fixing requirements of parts at different angles. The lateral frame has graduated values ​​on its top, providing intuitive guidance for adjusting the lateral fixture, significantly improving positioning accuracy, effectively reducing welding deviations, ensuring the consistency and mechanical properties of welded joints, and meeting the precision requirements of high-end manufacturing. During part welding, the lateral fixture can precisely fix the oblique interface of the part, avoiding interface misalignment caused by positioning offset, and improving the assembly accuracy of the welded parts.

[0020] 2. The welding machine relies on motor A and the advancing frame to move the laser welder back and forth, motor B and the horizontal adjustment frame to move it left and right, and motor C, the lifting frame, and cylinder A to lift it up and down, thus constructing a three-dimensional adjustable welding mechanism. It can quickly and accurately adjust the laser welder to the target position according to the different welding positions of the workpiece. It can adapt to parts of different specifications and welding requirements without changing tooling, which greatly improves the versatility of the device and the welding efficiency.

[0021] 3. After welding is completed, the clamping plate, side clamp, and blocking component automatically reset and release the workpiece. Then, the cylinder B drives the push plate to push the workpiece out along the guide groove and the blocking component. This realizes the fully automated connection of positioning, welding, and material discharge. There is no need for manual removal of parts, which reduces the labor intensity of operators, avoids workpiece damage caused by manual bumping, and shortens the single welding cycle time, thus improving the efficiency of mass production.

[0043] Among them, a cylinder A108 is fixedly installed at the upper front end of the lifting frame 107, and a laser welder 109 is installed at the bottom of the cylinder A108.

[0044] The base 2 has a side frame 3 on both sides of the top rear. Each side frame 3 has a side clamp 302 slidably connected to its top position. Each side clamp 302 has a threaded hole at its lower middle position. A screw 301 is rotatably connected to the upper part of the side frame 3.

[0045] The guide frame 201 has a workpiece 4 placed in the guide groove. The workpiece 4 is located between the two clamping plates 207. When the cylinder C204 is in the extended state, the left rear end of the blocking member 205 is in contact with the front end of the workpiece 4. When the cylinder C204 is in the retracted state, the through groove of the blocking member 205 is flush with the guide groove of the guide frame 201.

[0046] When using:

[0047] Workpiece 4 loading and preliminary positioning: Place the workpiece 4 to be welded into the guide groove of the guide frame 201, start the cylinder C204 to make it extend, at this time the left rear end of the blocking part 205 is in contact with the front end of the workpiece 4, start the cylinder B202 to drive the push plate 203 to move forward along the guide groove of the guide frame 201, push the front end of the workpiece 4 to fit tightly with the blocking part 205, and complete the front and rear position positioning and fixing of the workpiece 4.

[0048] Start the cylinders D206 on the left and right sides of the base 2 respectively.

[0052] Post-welding material arrangement process:

[0053] After welding is completed, the laser welder 109 is turned off. First, the cylinder D206 is controlled to retract, causing the clamping plate 207 to release the workpiece 4 from both sides. At the same time, the lateral clamp 302 is reset and released from the oblique side of the workpiece 4. Then, the cylinder C204 is started to retract, at which point the through groove of the blocking part 205 is flush with the guide groove of the guide frame 201. Finally, the cylinder B202 is started to drive the push plate 203 to push the workpiece 4 forward. The workpiece 4 passes through the guide groove of the guide frame 201 and the blocking part 205 and is discharged, completing one welding cycle and avoiding the need for manual removal of the workpiece after welding.
