A quick positioning mechanism for welding process

Abstract

This utility model relates to the field of welding processing technology and discloses a quick positioning mechanism for welding processing, including a first plate and a second plate disposed on one side of the first plate. Both the first and second plates have magnetic strips on their edges. The second plate is thinner than the first plate and can rotate within the first plate. An adjustment component is disposed between the first and second plates. When the operator needs to make unconventional limits on the welding angle of the workpiece, by loosening the abutment rod, the second plate can rotate within the limiting ring of the first plate in conjunction with the rotating cylinder, thereby adjusting the angle of the upper inclined surfaces of the first and second plates. During adjustment, the specific angle can be accurately calculated by observing the pointing scales of the initial and movable pins, thus improving the overall practicality and adaptability of the device.

Description

Technical Field

[0001] This utility model relates to the field of welding processing technology, specifically a rapid positioning mechanism for welding processing. Background Technology

[0002] In the field of welding, especially in the splicing and assembly of small workpieces, plates, or pipes, quickly, accurately, and stably fixing the workpiece to be welded at a preset position and angle is a key step in ensuring welding quality and improving production efficiency. Traditional fixing methods, such as using C-clamps or screw clamps, are relatively common, but they have disadvantages such as cumbersome operation, slow positioning speed, and poor adaptability to workpiece shapes.

[0003] To overcome the aforementioned problems, devices that utilize strong magnetism for adsorption and fixation, such as "strong magnetic fixers for welding," have emerged on the market. These devices can quickly adhere to steel workpieces and welding platforms through their magnetic surfaces, achieving temporary fixation of two or more workpieces and improving positioning efficiency to a certain extent.

[0004] However, these strong magnetic retainers have obvious limitations: they are usually designed as geometries with fixed angles and can only be used for welding operations at specific angles. This inherent angle limitation results in a serious lack of versatility, making it impossible to meet the welding positioning needs of non-standard angles or multi-angle and complex angle workpieces, and it is not applicable to non-standard angles. Utility Model Content

[0005] The purpose of this invention is to provide a rapid positioning mechanism for welding processes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quick positioning mechanism for welding processing, comprising a first plate and a second plate disposed on one side of the first plate, wherein magnetic strips are disposed on the edges of both the first plate and the second plate, the thickness of the second plate is less than that of the first plate, and the second plate can rotate within the first plate; A debugging component is disposed between the first and second modules; The debugging component includes a scale ring disposed on the surface of the first plate, and an abutment rod disposed above the scale ring and on the surface of the first plate for locking the angle of the second plate.

[0007] Preferably, the debugging component further includes a limiting ring disposed on the surface of the first plate, the scale ring disposed on the surface of the limiting ring, and a rotating cylinder rotatably connected inside the limiting ring, the rotating cylinder being fixed to the side of the second plate near the first plate.

[0008] Preferably, the scale ring consists of 360 pointers, of which four longer pointers represent 45°, 90°, 135° and 180° respectively.

[0009] Preferably, an initial needle is provided inside the scale ring. The initial needle is a fixed design. A movable needle is fixedly connected to the surface of the rotating cylinder. The angle between the movable needle and the initial needle is set to 90 degrees and is consistent with the angle of the upper inclined surface of the first plate and the second plate.

[0010] Preferably, the surface of the first plate has a through hole, the surface of the abutment rod has a threaded design, the abutment rod is threaded into the through hole, and its end abuts against the second plate.

[0011] Preferably, both the first and second plates have turn markings on their surfaces.

[0012] Preferably, the combined cross-section of the first and second plates is approximately an isosceles triangle or wedge shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When workers need to make unconventional limits on the welding angle of the workpiece, the second plate can be rotated within the limiting ring of the first plate by loosening the abutment rod. This allows the upper inclined surface angle of the first and second plates to be adjusted. During adjustment, the specific angle can be accurately calculated by observing the pointing scale of the initial needle and the movable needle, thereby improving the overall practicality and adaptability of the device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 - Figure 4 As shown, a quick positioning mechanism for welding processing includes a first plate 100 and a second plate 110 disposed on one side of the first plate 100. Magnetic strips 120 are disposed on the edges of both the first plate 100 and the second plate 110. The thickness of the second plate 110 is less than that of the first plate 100, and the second plate 110 can rotate within the first plate 100. The combined cross-section of the first plate 100 and the second plate 110 is approximately an isosceles triangle or wedge shape. In this embodiment, the upper end face, lower end face, and inclined surface of the first plate 100 and the second plate 110 are the main working positioning surfaces. By using the upper inclined surface of the first plate 100 and the second plate 110 in conjunction with the magnetic strip 120, the workpiece can be attracted and limited at an angle. By using the upper inclined surface of the first plate 100 in conjunction with the lower end face of the second plate 110, an angle limitation can be formed. By using the upper inclined surface of the first plate 100 in conjunction with the upper end face of the second plate 110, the workpiece can be limited at an angle. It should be noted that: Figure 1 Point A is the lower end face, point B is the included angle, point C is the upper inclined face, and the face opposite to point A is the upper end face; Debugging component 200 is located between the first plate 100 and the second plate 110; If some workpieces need to be welded at unconventional (specified) angles, the desired effect cannot be achieved through the multiple end faces of the first plate 100 and the second plate 110. The debugging component 200 includes a scale ring 215 disposed on the surface of the first plate 100, and an abutment rod 212 disposed above the scale ring 215 and on the surface of the first plate 100 for locking the angle of the second plate 110.

[0018] The debugging component 200 also includes a limiting ring 211 disposed on the surface of the first plate 100, a scale ring 215 disposed on the surface of the limiting ring 211, and a rotating cylinder 210 rotatably connected inside the limiting ring 211. The rotating cylinder 210 is fixed to the side of the second plate 110 near the first plate 100. The scale ring 215 consists of 360 pointers, of which four longer pointers represent 45°, 90°, 135° and 180° respectively. When encountering a workpiece that needs to be welded at a specified angle, the initial angle between the upper inclined surfaces of the first plate 100 and the second plate 110 is 90 degrees. If the angle is greater than 90 degrees, then the second plate 110 is turned clockwise to gradually increase the angle between the upper inclined surfaces of the first plate 100 and the second plate 110. Similarly, if the angle is less than 90 degrees, turn counterclockwise, and the angle between the upper slopes of the first plate 100 and the second plate 110 will be reduced. The scale ring 215 has an initial needle 214 inside. The initial needle 214 is a fixed design. The rotating cylinder 210 has a movable needle 216 fixedly connected to its surface. The angle between the movable needle 216 and the initial needle 214 is set to ninety degrees and is consistent with the angle of the upper inclined surface of the first plate 100 and the second plate 110. When adjusting the angles of the first plate 100 and the second plate 110, the initial needle 214 angle remains unchanged. Personnel only need to observe the angle of the movable needle 216 as it rotates with the rotating drum 210. At the same time, by cooperating with the scale of the scale ring 215, a more precise adjustment effect can be achieved, which can effectively improve the welding accuracy and welding quality. The surface of the first plate 100 has a through hole, and the surface of the abutment rod 212 has a threaded design. The abutment rod 212 is threaded into the through hole, and its end abuts against the second plate 110. After the above angle adjustment is completed, the staff will tighten the abutment rod 212 again so that its end abuts against the surface of the second plate 110 inside the first plate 100. At this time, the angle of the second plate 110 can be limited by friction. Then, the staff will attach the two welded parts to the upper inclined surfaces of the first plate 100 and the second plate 110 to form the expected angle. Both the first section 100 and the second section 110 have turn signs 213 on their surfaces.

[0019] Working principle: First, loosen the abutment rod 212 counterclockwise to separate its rear end from the second plate 110, thus releasing the lock on the second plate 110. Then, according to the required angle, manually rotate the second plate 110 around the axis of the rotating drum 210. During the rotation, the operator observes the position change of the movable pin 216 fixed on the rotating drum 210 relative to the fixed initial pin 214 on the scale. When the movable pin 216 indicates the corresponding target angle on the scale, the rotation stops. Finally, tighten the abutment rod 212 clockwise so that its lower end firmly abuts against the back of the second plate 110. The static friction generated securely locks the second plate 110 at the current angle. At this point, the workpiece to be welded can be adsorbed onto the working surfaces of the magnetic strips 120 of the first plate 100 and the second plate 110, respectively. This achieves stepless and precise angle adjustment, greatly improving the flexibility of positioning and welding accuracy.
