Description

Technical Field

[0001] The utility model relates to the field of plate welding, in particular to a novel hinge welding positioning tool. Background Art

[0002] Welding is used to make products to enhance their strength, improve their durability, and increase their versatility, making them more solid. Products include but are not limited to door panels, bed frames, desks, filing cabinets, kitchen utensils, etc. Cold plates and carbon steel plates are often used for welding. Welding is often used in steel products industries, such as furniture, kitchen utensils, etc.

[0003] When welding welding accessories such as hinges, it is necessary to fix the position of the plate and the hinge at the same time. Traditional hinge welding is usually done by manually placing the pin into the process hole position of the plate and the hinge to fix it. When welding the plate, it is necessary to manually keep the pin position vertically fixed so that the plate and the hinge are firmly fixed. After spot welding the hinge position multiple times, the pin is manually removed to complete the welding. In order to improve efficiency, save costs, omit the manual pin placement process, and increase the welding diversity of welding tooling, a new hinge welding positioning tool is proposed to improve this problem. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a novel hinge welding positioning tool, which produces a technical effect of a one-time welding operation for welding and forming accessories such as plate hinges.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: comprising a copper rod, a brass plate mounted on the copper rod, and a copper plate arranged on the brass plate, the execution command comprises a lifting cylinder and a cylindrical rod fixed on the lifting cylinder and a cylinder top plate thereof, which are arranged vertically and the lifting speed is controlled by a throttle valve;

[0006] As a preferred technical solution of the utility model, the brass plate is fixedly connected to the copper plate, which is characterized in that the copper piece has good electrical conductivity and can form a good conductive welding local area network;

[0007] As a preferred technical solution of the utility model, its structure is that the cylinder lifts the fixed rod to position the process hole of the plate, which is simpler to operate and more accurate in positioning;

[0008] As a preferred technical solution of the utility model, the tooling cylinder is controlled by a throttle valve, and the positioning speed can be adjusted according to the welding conditions to achieve the most perfect welding effect.

[0009] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0010] 1. The utility model places the plate to be welded on the fixture after it overlaps with the hinge positioning hole, and fixes the two sets of plates through the positioning holes, and uses the lifting effect of the cylinder to fix the two plates firmly at the same time, and then the subsequent spot welding action can be carried out. This tooling greatly improves the welding efficiency, avoids the steps of manual positioning, saves time and labor costs, and at the same time, the positioning accuracy is significantly improved, avoiding the disadvantages of insufficient manual positioning accuracy, and greatly improving the welding efficiency and welding yield rate.

[0011] 2. Welding positioning greatly saves production time. At the same time, without the need to weld hinges, there is no need to replace or unload the tooling, and only the cylinder needs to be reset to zero. Compared with traditional welding tooling, it saves the time for tooling replacement and greatly improves production efficiency.

[0012] 3. Compared with the traditional plane welding method, this welding tool is mainly made of brass and copper, and the conductive welding effect is more ideal. At the same time, compared with other welding tools, it is small in size, and the welding plane can be adjusted according to actual conditions, which greatly improves the problem of space occupation.
