Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, in particular to an automatic welding device for aluminum studs. Background Art

[0002] In modern industrial production, the welding of aluminum studs is a crucial process. Aluminum, a widely used metal material, boasts numerous advantages, including lightweight and corrosion resistance, and is widely used in aerospace, automotive, and electronic equipment. As a connecting component, the welding quality of aluminum studs directly impacts the overall performance and reliability of the product.

[0003] In the traditional aluminum stud welding mode, the grounding electrode is mostly set on the robot gripper, which places extremely high performance requirements on the robot gripper, requiring the robot gripper to have higher precision, stability and load-bearing capacity; at the same time, depending on the size of the robot gripper, the grounding electrode needs to be replaced frequently, which increases labor intensity and welding costs; more importantly, since the welded workpiece is generally large or the stud is far away from the grounding electrode, the welding effect will be poor, which will lead to frequent cold welds in the stud welding, unstable quality, and an increase in defective products.

[0004] Therefore, there is an urgent need for a new type of automatic aluminum stud welding device that can effectively improve welding efficiency and quality, reduce labor intensity and safety risks, and avoid the problems of traditional welding methods caused by robot gripper performance and cost issues. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an automatic welding device for aluminum studs, which can effectively improve welding efficiency and quality, reduce labor intensity, and reduce cost consumption.

[0006] The utility model solves the technical problem by adopting the following technical solutions:

[0007] An automatic welding device for aluminum studs, comprising:

[0008] A welding frame, a stud welding gun, an insulating sleeve, a floating mechanism, a connector and a grounding electrode. A vertical plate is provided at one end of the welding frame, a stud welding gun is fixedly mounted on one side of the vertical plate, an L-shaped connector is fixedly connected to the bottom of the vertical plate, an insulating sleeve is fixedly mounted on the other end of the L-shaped connector by bolts, the floating mechanism is passed through the insulating sleeve, and a grounding electrode is fixedly mounted on the bottom end of the floating mechanism by bolts.

[0009] Moreover, the floating mechanism includes a guide column and a compression spring. The guide column is inserted into the insulating sleeve, and the compression spring is sleeved on the outside of the guide column.

[0010] Moreover, the insulating sleeve assembly includes a left insulating sleeve and a right insulating sleeve. The left insulating sleeve and the right insulating sleeve are locked on both sides of the compression spring by bolts and fixed to one end of the L-shaped connector.

[0011] Moreover, the welding frame further comprises a base and a connecting rod, wherein the base is fixedly mounted on the bottom of the connecting rod, and a vertical plate is fixedly mounted on the other end of the connecting rod.

[0012] The advantages and positive effects of the utility model are:

[0013] The utility model arranges the grounding electrode at the bottom of the floating mechanism, replacing the previous structure of placing the grounding electrode on the robot gripper, thereby greatly reducing the number of grounding electrodes, simplifying the structure of the robot gripper, saving costs, and ensuring the stability of the aluminum stud welding quality.

[0014] The utility model is provided with a floating mechanism and a compression spring in the floating mechanism. The aluminum stud is welded by the reaction force of the compression spring during the welding process, thereby avoiding the frequent occurrence of cold welds during the welding process of the aluminum stud, effectively improving the welding strength of the aluminum stud and ensuring the welding quality.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through specific embodiments. The following embodiments are merely illustrative and non-restrictive, and should not be used to limit the scope of protection of the present invention.

[0020] An automatic welding device for aluminum studs, comprising:

[0021] Welding frame, stud welding gun, insulating sleeve, floating mechanism, connector and grounding electrode. A vertical plate 2 is provided at one end of the welding frame, a stud welding gun 1 is fixedly installed on one side of the vertical plate 2, an L-shaped connector 9 is fixedly connected to the bottom of the vertical plate 2, and an insulating sleeve 3 is bolted to the other end of the L-shaped connector 9. The floating mechanism is passed through the insulating sleeve 3, and a grounding electrode 11 is bolted to the bottom end of the floating mechanism.

[0022] The floating mechanism includes a guide post 10 and a compression spring 6. The guide post 10 is inserted into the insulating sleeve 3, and the compression spring 6 is sheathed on the outside of the guide post 10. The reaction force of the compression spring 6 is used to fine-tune the ground electrode 11.

[0023] The insulating sleeve assembly 3 comprises a left insulating sleeve half 7 and a right insulating sleeve half 8, which are bolted to either side of a compression spring 6 and fixed to one end of an L-shaped connector 9. The presence of the insulating sleeve assembly 3 allows for fine-tuning of the floating mechanism's vertical position, thereby adjusting the ground electrode 11 according to the size of the robot gripper or the welded workpiece.

[0024] The welding frame further includes a base 5 and a connecting rod 4 . The base 5 is fixed to the bottom of the connecting rod 4 , and a vertical plate 2 is fixed to the other end of the connecting rod 4 .

[0025] Working principle:

[0026] The robot gripper sends the workpiece between the ground electrode and the base and presses the ground electrode. At this time, the compression spring in the floating mechanism will generate a reaction force due to the compression of the workpiece. This reaction force will cause the ground electrode to align with the upper electrode on the stud welding gun and make fine adjustments, thereby realizing the welding of aluminum studs. This welding method effectively ensures welding quality and saves costs.

[0027] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will understand that various replacements, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
