Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a precision positioning device for metal welding. Background Art

[0002] In the field of metal processing, welding is a common connection method used to firmly connect two or more metal workpieces. However, during the welding process, the positioning and angle fixation of the workpieces directly affect the quality and accuracy of the welding. Traditional welding positioning methods often rely on manual clamping or the use of simple positioning fixtures, but these methods have problems such as low positioning accuracy, cumbersome operation, and difficulty in maintaining the welding angle.

[0003] In addition, the surface of the workpiece is not always smooth and flat. When welding metal materials such as steel pipes and steel plates, surface protrusions or irregularities may cause the positioning fixture to fit unstablely with the workpiece, resulting in tilt, thereby affecting the stability of the welding angle and reducing welding accuracy.

[0004] To this end, we proposed a precision positioning device for metal welding. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] See also Figures 1-2 In an embodiment of the present invention, a precision positioning device for metal welding includes a positioning plate 1, a strong magnet 3 and an edge supporting mechanism.

[0022] There are two positioning plates 1, and a strong magnet 3 is fixedly connected between the two positioning plates 1. The edge of the positioning plate 1 is provided with an edge supporting mechanism, and the edge supporting mechanism includes a U-shaped plate 7. A sliding groove 4 is opened on the outer surface edge of the positioning plate 1, and two U-shaped plates 7 are slidably connected to the sliding groove 4. The inner end surfaces on both sides of the U-shaped plate 7 are fixedly connected with sliders 9, and the sliders 9 on both sides are respectively slidably connected to the corresponding sliding grooves 4 on the front and rear positioning plates 1. The outer surface of the U-shaped plate 7 is threadedly connected with a locking block 8, which passes through the inner walls of the U-shaped plate 7 and the slider 9 and contacts the receiving groove 5.

[0023] It should be noted that the edge support mechanism is mainly used to solve the problem that the positioning plate 1 cannot fully fit with the surface of the welding part. When there are protrusions or unevenness on the surface of the welding part, the edge of the positioning plate 1 is difficult to fit tightly with the welding part, which may cause the positioning plate 1 and the welding part to tilt, making it difficult to maintain a stable welding angle. The position of the U-shaped plate 7 is adjusted by sliding the slider 9 in the sliding groove 4, so that it can fully fit with the surface of the workpiece, avoiding the tilting caused by the edge of the positioning plate 1 unable to fit the workpiece, and ensuring the fitting stability between the positioning plate 1 and the welding part. The outer surface of the U-shaped plate 7 is threadedly connected with a locking block 8. After adjusting the position of the U-shaped plate 7 so that it fully fits with the surface of the workpiece, the locking block 8 can be tightened to fix the position of the U-shaped plate 7, ensuring that the angle of the positioning plate 1 is fixed during welding, thereby improving the accuracy and stability of welding and avoiding the decline in welding quality due to changes in welding angle.

[0024] Both ends of the sliding groove 4 are provided with inward lifting grooves 6 , and the side surface of the positioning plate 1 is provided with two symmetrically distributed receiving grooves 5 , and the receiving grooves 5 are located directly below the lifting grooves 6 .

[0025] It should be noted that when the edge supporting mechanism is not in use, the U-shaped plate 7 can be slid along the sliding groove 4 toward the lifting groove 6, and then the U-shaped plate 7 can be guided into the storage groove 5 through the structure of the lifting groove 6, so that it can be stored at the edge position of the positioning plate 1, making the entire device more compact and flat, without affecting the welding operation. This not only makes it convenient to hide the edge supporting mechanism when the surface of the workpiece is flat, but also reduces the exposure of the U-shaped plate 7, thereby improving the overall flexibility and operability of the device.

[0026] The outer surface of the positioning plate 1 is provided with a transparent taking groove 2, which makes it easy for the operator to take and adjust the positioning plate 1 during use. The material of the U-shaped plate 7 is ABS resin, which is durable, lightweight and has good impact resistance, thereby extending the service life of the device.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
