Description

Technical Field

[0001] The utility model relates to the technical field of assembly machinery, in particular to a stainless steel automatic welding frame. Background Art

[0002] At present, laser automatic welding is often required in the automatic assembly process of stainless steel mechanical parts. Due to the small, precise and thin parts, there are problems such as loose welds, over-welding and black welds during the welding process. The product yield is low, resulting in a low degree of automation.

[0003] The authorization announcement number in the prior art is: CN211680664U, and the name is a stainless steel automatic welding positioning mechanism, which is mainly composed of components such as a workbench, a fixed box, a welding port and a positioning mechanism. A fixed box is fixedly installed on the workbench, and the upper end surface of the fixed box is provided with a welding port for welding operations. Above the workbench, positioning mechanisms are symmetrically installed on the left and right sides. The main function of these positioning mechanisms is to accurately position the stainless steel before welding to ensure that it is in the correct welding position. In order to achieve precise positioning, the positioning mechanism adopts key components such as a guide rod, a first bevel gear and a pressure plate. The synergistic effect of these components enables the stainless steel to remain stable during the automatic welding process and is not prone to offset. This patent effectively solves the problem of easy offset of the fixture during automatic welding of stainless steel in the prior art, thereby avoiding the occurrence of stainless steel positioning welding errors and greatly improving the welding quality of stainless steel. However, this patent requires manual fixed welding and has a low degree of automation.

[0004] The application publication number in the prior art is: CN116329712A, and the name is a stainless steel welded pipe automatic processing equipment and method. The core part of the argon arc welding pipe automatic welding machine, in addition to its welding function, also adds a rotating mechanism for more flexibly adjusting the welding angle and direction, making the welding process smoother and more efficient. The patent is also equipped with a sealing mechanism. Before welding, the seal will move to the side close to each other, thereby automatically sealing the front and back sides of the stainless steel welded pipe. In addition, by fixing the sealing frame and rotating the sealing frame, the patent can also effectively seal the gap between the stainless steel welded pipe and the machine cover and the argon arc welding pipe automatic welding machine. This design enables the stainless steel welded pipe to automatically complete the sealing work before welding begins, without the need for additional manual sealing operations, which not only greatly saves time and improves welding efficiency, but also effectively prevents gas leakage during welding, thereby ensuring welding quality. However, this patent has the same problem as the above-mentioned patent. Although the sealing is better, the degree of automation is low. Utility Model Content

[0021] The specific implementation process of the utility model is as follows: This stainless steel automatic welding frame is a key component in the automatic production line equipment, and needs to be used together with other components in the equipment to complete the automatic welding process. For example, the front and rear ends of the automatic welding frame need to add a conveying manipulator and a laser head for welding, etc. However, the structures such as the mechanical conveying hand are all existing technologies, so they will not be repeated;

[0022] Step 1: The 45-degree rotating cylinder 35 on the supporting base 12 is reset, the fixture base 32 returns to a horizontal state, and the double-hole blowing nozzle 21 is placed in a striking state to prepare for placing the fixture 33, and then the product 34 is placed inside the fixture 33;

[0023] Step 2: The front-end mechanical arm places the jig 33, which has already installed the product 34 in the previous station, on the jig base 32, and the positioning clamp 36 clamps the jig, and then the 45-degree rotating cylinder 35 is actuated to rotate the rotary welding mechanism 3 45 degrees;

[0024] Step 3: After the fixture is rotated into place, the air blow drives the cylinder 23 to move, driving the 90-degree rotating arm 22 to rotate 90 degrees, driving the double-hole air blowing nozzle 21 to approach the product 34 of the fixture 33 and align with the welding point on the product;

[0025] Step 4: When the matching assembly equipment system starts laser welding, the double-hole air blowing nozzle 21 sprays air until the laser welding is completed. After the delayed jet, the air blowing pushes the cylinder 23 to move again, and the double-hole air blowing nozzle 21 is reset. At the same time, the 45-degree rotating cylinder 35 is reset, and the rotary welding mechanism 3 returns to the horizontal head state, and the product 34 and the fixture 33 are sent away through the rear-end mechanical arm. At this point, the entire welding process has been completed, and then the next cycle is automatically carried out. The utility model is used in conjunction with the assembly equipment, and the operation is simple. After setting the parameters once, the equipment is started, and each mechanism automatically works each component, automatically completing the process of placing products, welding products, and conveying products. After completion, the next cycle is automatically carried out; the utility model adopts full automation, and the operator only needs to set the relevant technical parameters to realize automatic rotation welding angle, automatic welding, automatic rotation air blowing rotating arm and automatic blowing, so as to achieve the same matching use with the assembly machine, with a high degree of automation and improved production efficiency.

[0026] Furthermore, the assembly of the utility model is accurate and fast, the welding points do not turn black, and the welding points remain good for a long time, which can greatly improve production efficiency and product quality rate, reduce production costs, and the utility model has a wide range of applications and can be used in similar automated welding automated production lines.
