Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding device for metal door processing. Background Technology
[0002] In the welding process of metal door frames, there are usually multiple angles (such as 90° right angle, 45° oblique angle) at the connection between the top frame and the side frame. At present, most small and medium-sized enterprises still use manual hand-held welding guns for the operation, which is not only inefficient, but also the welding quality is highly dependent on the operator's experience, and problems such as uneven weld and welding deformation are easy to occur.
[0003] Currently, although there are some fixed welding fixtures, they generally lack flexible welding gun angle adjustment functions, making it difficult to adapt to welding door frames of different specifications and angles, resulting in a narrow processing application range and difficulty in guaranteeing accuracy. Utility Model Content
[0004] The purpose of this utility model is to provide a welding device for metal door processing, which avoids uneven welds, burn-through, or lack of fusion caused by unstable manual operation.
[0005] This utility model provides a welding device for metal door processing, including a base, on which a positioning and clamping mechanism for positioning and clamping the top frame and the side frame of a metal door frame is provided; The base is provided with a horizontal adjustment mechanism above it, and the horizontal adjustment mechanism is provided with a vertical adjustment mechanism. Two sets of welding actuators are symmetrically arranged on the longitudinal adjustment mechanism; The welding actuator includes a locator fixed to the longitudinal adjustment mechanism, a disc hinged to the locator, a slide plate fixed to the outer wall of the disc, and a welding torch sleeve slidably connected to the slide plate groove via a grooved wheel. The disc is rotatably connected to the card seat via a pin and can be locked at multiple different angular positions relative to the card seat, so that the sliding angle of the sliding plate is adapted to the angle of the welded joint of the door frame.
[0006] Preferably, the positioning and clamping mechanism includes: A first groove is formed on the short side of the base to accommodate the top frame; A second groove is formed along the two long sides of the base to accommodate the frame; A clamping structure disposed in the second groove; The clamping structure includes a screw threaded to the base, a knob located at one end of the screw, and a rectangular plate connected to the other end of the screw via a bearing. The rectangular plate is used to clamp the frame.
[0007] Preferably, the lateral adjustment mechanism includes: Two sliding blocks are respectively located at the two short sides of the top of the base; The first slider is slidably connected to each slider block; The first slider is locked to the slide block by a positioning pin.
[0008] Preferably, the longitudinal adjustment mechanism includes: Two circular tubes are fixedly connected between the two first sliders; A second slider is slidably connected to the outer wall of the circular tube; The second slider is locked to the round tube by bolts, and the card holder is fixed to the second slider.
[0009] Preferably, the disc can be locked in a 90-degree upright position or a 45-degree tilt position relative to the card holder.
[0010] Preferably, the slide plate is a straight slide plate.
[0011] Preferably, the axis of the welding torch sleeve is perpendicular to the extension direction of the groove of the chute plate.
[0012] Preferably, the depths of the first and second grooves are adapted to the thickness of the door frame profile.
[0013] This utility model provides a welding device for metal door processing: By using a combination of a mounting base, a disc, a sliding plate, and a welding torch sleeve, the locking pin of the disc is loosened according to the angle of the corner seam to be welded. The disc is then rotated, causing the sliding plate on it to rotate as well, until the extension direction of the sliding plate is completely aligned with the direction of the corner seam of the door frame. The welding torch is then inserted into the welding torch sleeve, and the sliding plate guides the welding torch to move at a uniform speed along the joint direction, avoiding problems such as uneven welds, burn-through, or incomplete fusion caused by unstable manual operation. The disc can be locked at multiple angles (such as 90° and 45°) to adapt to the welding needs of door frame joints at different angles. Through the cooperation of the groove and the clamping structure, the door frame can be quickly positioned and firmly clamped, preventing displacement during the welding process.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] In this embodiment, as Figure 1 and Figure 2 As shown, a welding device for metal door processing includes a base 1, on which a positioning and clamping mechanism for positioning and clamping the top frame and side frame of a metal door frame is provided; a horizontal adjustment mechanism is provided above the base 1, and a vertical adjustment mechanism is provided on the horizontal adjustment mechanism. Two sets of welding actuators are symmetrically arranged on the longitudinal adjustment mechanism. The welding actuator includes a card seat 6 fixed to the longitudinal adjustment mechanism, a disc 7 hinged to the card seat 6, a slide plate 8 fixed to the outer wall of the disc 7, and a welding gun sleeve 9 slidably connected to the slide plate 8 in the slide groove through a grooved wheel. The disc 7 is rotatably connected to the card seat 6 through a pin and can be locked in multiple different angular positions relative to the card seat 6 so that the slide groove angle of the slide plate 8 is adapted to the angle of the weld joint of the door frame.
[0021] Therefore, according to the angle of the corner seam to be welded, loosen the locking pin of the disc 7, rotate the disc 7, and drive the sliding plate 8 on it to rotate together until the extension direction of the sliding plate is completely consistent with the direction of the corner seam of the door frame. Insert the welding torch into the welding torch sleeve 9, ignite the welding torch and preheat the welding wire. The operator holds the welding torch and slides it at a uniform speed along the sliding plate 8 to ensure that the direction of the weld is consistent with the joint and improve the welding quality. Specifically, the card holder 6 has an inwardly recessed groove, the disc 7 can rotate in the groove, the slide plate 8 deflects with the disc 7, the welding gun sleeve 9 needs to be prefabricated, the inner diameter of the welding gun sleeve 9 needs to be adapted to the barrel of the welding gun, the groove wheel is designed with two embedded in the edge of the slide plate 8, the disc 7 is provided with multiple angle positioning holes, the card holder 6 is provided with corresponding locking pin holes, and the disc angle is fixed by the pin.
[0022] In some embodiments, such as Figure 3As shown, the positioning and clamping mechanism includes: a first groove 10 formed on the short side of the base 1 for accommodating the top frame; a second groove 11 formed on the two long sides of the base 1 for accommodating the frame; and a clamping structure 12 disposed in the second groove 11. The clamping structure 12 includes a screw 1201 threadedly connected to the base 1, a knob 1202 disposed at one end of the screw 1201, and a rectangular plate 1203 connected to the other end of the screw 1201 via a bearing. The rectangular plate 1203 is used to clamp the frame.
[0023] Specifically, the depths of the first groove 10 and the second groove 11 are matched with the thickness of the door frame profile to ensure that the door frame is stable and does not wobble after being embedded. By rotating the knob 1202, the drive screw 1201 pushes the rectangular plate 1203 forward, firmly pressing the frame against the second groove 11 to prevent the door frame from shifting during the welding process.
[0024] In some embodiments, such as Figure 4 As shown, the lateral adjustment mechanism includes: two slide blocks 2 located at the two short sides of the top of the base 1; a first slider 3 slidably connected to each slide block 2; and the first slider 3 locked to the slide block 2 by a positioning pin. Specifically, the first slider 3 moves laterally along the slide block 2 to achieve coarse adjustment of the lateral position of the welding gun, and the positioning pin is inserted to fix the position.
[0025] In some embodiments, such as Figure 4 As shown, the longitudinal adjustment mechanism includes: two round tubes 4 fixedly connected between two first sliders 3; a second slider 5 slidably connected to the outer wall of the round tubes 4; the second slider 5 is locked to the round tubes 4 by bolts, and the bracket 6 is fixed on the second slider 5; Specifically, the second slider 5 moves longitudinally along the circular tube 4 to achieve fine adjustment of the longitudinal position of the welding gun, and the position is fixed after the bolt is tightened. It should be noted that the circular tube 4 serves as a guide rail, which has a simple structure and good rigidity, facilitating the smooth sliding of the second slider 5.
[0026] In some embodiments, such as Figure 5 As shown, the disc 7 can be locked in a 90-degree upright position or a 45-degree tilted position relative to the card holder 6; Specifically, the angle of the disc 7 is locked by a pin to ensure that the sliding direction of the slide plate 8 is consistent with the door frame joint.
[0027] In some embodiments, such as Figure 5 As shown, the slide plate 8 is a straight slide plate.
[0028] Specifically, the linear chute has a simple structure, is easy to manufacture, and can effectively guide the linear movement of the welding torch; It should be noted that the chute plate 8 can be cut from steel plate, and the inner surface of the chute is smooth, which reduces the resistance of the welding torch movement.
[0029] In some embodiments, such as Figure 4 As shown, the axis of the welding torch sleeve 9 is perpendicular to the extension direction of the groove of the slide plate 8; Specifically, this structure ensures that the welding wire remains perpendicular to the joint as the welding torch moves within the chute.
[0030] In some embodiments, such as Figure 1 As shown, the depths of the first groove 10 and the second groove 11 are adapted to the thickness of the door frame profile; Specifically, the groove depth is slightly less than the profile thickness to facilitate quick placement and positioning, while preventing welding heat from being conducted to the base 1.
[0031] The working principle of this application is illustrated below with a preferred embodiment: Place the assembled metal door frame on the base 1, so that the top frame is inserted into the first groove 10 and the two side frames are inserted into the corresponding second grooves 11. Rotate the knobs 1202 of the two side clamping structures 12 to drive the rectangular plate 1203 forward until the two side frames are firmly pressed against the side walls of the grooves, thus completing the positioning and clamping of the door frame; Based on the location of the corner seam to be welded, first loosen the positioning pin of the lateral adjustment mechanism, move the first slider 3, and perform a rough lateral adjustment; then loosen the bolt of the longitudinal adjustment mechanism, move the second slider 5, and perform a fine longitudinal adjustment, so that the outlet end of the welding torch sleeve 9 is roughly aligned with the start of the weld; based on the angle of the corner seam to be welded (e.g., 90° or 45°), loosen the locking pin of the disc 7, rotate the disc 7, and rotate the sliding plate 8 on it together until the extension direction of the sliding plate is completely consistent with the direction of the corner seam of the door frame. Then, insert the locking pin to fix the disc 7 at the working angle; Insert the welding torch into the torch sleeve 9, ignite the torch, and preheat the welding wire. The operator holds the torch and slides it at a constant speed along the groove of the slide plate 8. Under the forced guidance of the groove, the torch will move strictly along a trajectory parallel to the joint, thus producing a high-quality weld that is uniform, straight, and has consistent penetration depth in one go.
[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
