Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and belongs to a welding fixture for anti-deformation robots. Background Technology

[0002] During welding, the workpiece is subjected to an uneven temperature field, causing changes in its shape and size; this is known as welding deformation. During welding, the workpiece undergoes corresponding deformation as the temperature changes; this deformation is called instantaneous welding deformation. After welding, when the workpiece has completely cooled to its initial temperature, some deformation may still occur; this is defined as residual welding deformation.

[0003] In welding production, welding deformation is prevalent in all welded workpieces. Once the deformation of a welded workpiece exceeds the tolerance requirements specified in the welding workpiece drawings, it becomes particularly necessary to conduct in-depth research on the reverse deformation of the welded workpiece in order to meet the drawing standards and improve production efficiency.

[0004] Traditional manual welding methods and ordinary automated welding techniques are both difficult to effectively control deformation. This anti-deformation robotic welding equipment aims to achieve high-quality, low-deformation welding operations by leveraging the high-precision motion control capabilities of robots and integrating advanced anti-deformation technology. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an anti-deformation robot welding fixture.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This application provides an anti-deformation robot welding fixture, including a mounting base plate. The mounting base plate is provided with an anti-splash component and a positioning component. The anti-splash component includes a leveling plate, which is fixedly connected to the mounting base plate. The positioning component includes an anti-deformation component and a lateral positioning component. The anti-deformation component is located on the long side of the leveling plate, and the lateral positioning component is located on the short side of the leveling plate. A clamping cylinder is provided between the leveling plates and is fixedly connected to the middle of the mounting base plate. A positioning cylinder is provided on one side of the mounting base plate, and a quick-clamping component for clamping and fixing the product is provided on one side of the clamping cylinder.

[0008] Preferably, the anti-splash component further includes leveling pins, which are fixedly connected to the mounting base plate and located on both sides of the clamping cylinder.

[0009] Preferably, the anti-deformation component includes a positioning plate, which is positioned to the mounting base plate by a positioning pin, and the top surface of the positioning plate is provided with an anti-misalignment plate.

[0010] Preferably, the side-mounting assembly includes a first mounting pin and a second mounting pin. The first mounting pin is close to the leveling pad and connected to the mounting base plate, and the second mounting pin is close to the clamping cylinder and connected to the mounting base plate.

[0011] Preferably, the output end of the clamping cylinder is connected to a clamping push plate, and a screw is threadedly connected to the clamping push plate, and a screw cap is threadedly connected to the screw.

[0013] Preferably, the quick-clamp assembly includes a quick-clamp square steel, which is mounted on the mounting base plate, and quick clamps are connected to the quick-clamp square steel via a connecting seat.

[0014] Compared with the prior art, this utility model provides an anti-deformation robot welding fixture, which has the following beneficial effects:

[0015] 1. Reduced deformation: It can effectively offset the deformation generated during the welding process, making the welded parts closer to the shape and size required by the design after welding, thus improving the accuracy of the welded parts. During robot welding, parameters such as welding speed, angle, and heat input can be precisely controlled to maintain the stability of the welding process and further reduce the deformation caused by fluctuations in welding parameters.

[0016] 2. Ensuring weld quality: The robot performs welding according to the preset program and path, which can ensure the uniformity, consistency and continuity of the weld, and avoid defects such as uneven weld width, uneven height, undercut and incomplete penetration that may occur when welding manually. This significantly improves both the appearance and internal quality of the weld.

[0017] Third, achieving automated continuous operation: The robot can work 24 hours a day without interruption. The use of welding anti-deformation tooling reduces the adjustment and repair time during the welding process, enabling robot welding to proceed more smoothly and further improving production efficiency.

[0018] Fourth, cost reduction: Robotic welding replaces a large amount of manual welding work, reducing reliance on skilled welders and lowering labor costs, thus saving companies significant labor expenses. The use of reverse deformation welding technology reduces the scrap rate and rework rate of welded parts, indirectly lowering production costs as well.

[0019] The features and advantages of this utility model will be described in detail through embodiments and in conjunction with the accompanying drawings. Attached Figure Description

The mounting base plate 1 is provided with an anti-splash component 2 and a positioning component 3. The anti-splash component 2 includes a leveling plate 21, which is fixedly connected to the mounting base plate 1. The positioning component 3 includes an anti-deformation component 31 and a side-aligning component 32. The anti-deformation component 31 is located on the long side of the leveling plate 21, and the side-aligning component 32 is located on the short side of the leveling plate 21. A clamping cylinder 4 is provided between the leveling plates 21, which is fixedly connected to the middle of the mounting base plate 1. A positioning cylinder 5 is provided on one side of the mounting base plate 1, and a quick-clamping component 6 for pressing and fixing the product is provided on one side of the clamping cylinder 4.

[0027] Specifically, the anti-splash component 2 also includes a height equalizing pin 22, which is fixedly connected to the mounting base plate 1 and located on both sides of the clamping cylinder 4. The anti-splash component 2 is mainly used to position product parts, ensure the height difference dimension, and raise the product to prevent welding slag from accumulating and affecting positioning.

[0028] Specifically, the anti-deformation component 31 includes a positioning plate 311, which is positioned on the mounting base plate 1 by a positioning pin 312. The top surface of the positioning plate 311 is provided with an anti-misalignment plate 313. The anti-deformation component 31 is mainly used to position product parts and ensure product length. It first artificially deforms the weldment in the opposite direction to the welding deformation so that the weldment reaches the shape and size required by the design after welding.

[0029] Specifically, the side positioning component 32 includes a first positioning pin 321 and a second positioning pin 322. The first positioning pin 321 is close to the equal height pad 21 and connected to the mounting base plate 1. The second positioning pin 322 is close to the clamping cylinder 4 and connected to the mounting base plate 1. The side positioning component 32 is used to position product parts and ensure the consistency of side dimensions.

[0030] See Figure 2 , Figure 3 Specifically, the output end of the clamping cylinder 4 is connected to a clamping push plate 41, and a screw 42 is threadedly connected to the clamping push plate 41. The screw 42 is threadedly connected to a screw cap 43. The clamping cylinder 4 is used to clamp the product parts to ensure rigidity and reduce the amount of deformation during the welding process of the weldment.

[0031] See Figure 2 , Figure 4 Specifically, the bottom of the positioning cylinder 5 is connected to the cylinder mounting plate 51, the cylinder mounting plate 51 is fixedly connected to the mounting base plate 1, the output end of the positioning cylinder 5 is connected to the positioning push plate 52, the positioning push plate 52 is connected to the guide pin 53 and the positioning screw 54, the positioning screw 54 is located between the guide pin 53, the positioning cylinder 5 is used for automated positioning of product parts, and automatically exits through cylinder control after welding is completed.

[0032] See Figure 2 Specifically, the quick-clamp assembly 6 includes a quick-clamp square steel 61, which is mounted on the mounting base plate 1. A quick-clamp 62 is connected to the quick-clamp square steel 61 via a connecting seat, and the quick-clamp 62 can press and fix the product.

[0033] The working principle of this utility model:

[0034] Step 1: Place the product support strip on the leveling plate 21, with one side attached to the positioning plate 311. Before welding, calculations and thermal motion simulations were performed, and the welding deformation direction was inward. Therefore, the distance between the two positioning plates 311 is larger than that of the standard ruler. One end of the product is aligned with the positioning pin 321. Since the product parts are close to rectangular, care must be taken to prevent misalignment during installation. At this time, the misalignment prevention plate 313 plays the role of preventing misalignment.

[0035] Step 2: Press the cylinder switch component to start the cylinder 4, which will drive the screw nut 43 to advance and completely fix the product support bar.

[0036] Step 3: Place the product motherboard on the equal height pin 22, with one side of the product aligned with the second positioning pin 322 and the other side aligned with the positioning screw 54 on the positioning cylinder 5. Then, use the quick clamp 62 on the quick clamp assembly 6 to press down and hold the product motherboard in place, thus fixing it completely.

[0037] Step 4: The positioning screw 54 that was originally extended on the positioning cylinder 5 retracts to avoid the welding position required for the product;

[0038] Step 5: Spray anti-splatter to reduce slag adhesion and minimize slag sticking during welding;

[0039] Step 6: Press the robot switch to start the formal welding process; the first step is to reverse the residual deformation of the workpiece during clamping, and the second step is to use a cylinder to tighten the workpiece to rigidly fix it during welding, reducing instantaneous deformation during welding. By using robotic welding for production, the impact of personnel, machines, materials, methods and environment on welding is further minimized.

[0040] Step 7: After completing the robot welding, press the cylinder switch component to tighten cylinder 4 and retract it, then remove the welded product.

[0041] Step 8: The positioning screw 54 on the positioning cylinder 5 extends forward and returns to the initial position of the tooling.

[0042] Step 9: Repeat welding for reuse.

[0043] The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
