Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy welding technology, specifically to an aluminum alloy welding auxiliary device with a precise docking and fixing structure. Background Technology

[0002] Aluminum alloy is a metal composite material. Aluminum alloy processing includes a welding process. Welding uses heating or pressure to stably connect two metal objects. Welding requires auxiliary devices, which can position, clamp, support, and move the workpieces, ensuring the safety of the welding operation and improving the welding quality.

[0003] Currently, welding auxiliary devices still have certain shortcomings, such as difficulty in ensuring welding quality and efficiency.

[0004] To overcome the problems of low welding quality and efficiency, a prior art Chinese patent (publication number: CN222740668U) discloses a rapid butt welding auxiliary device for metal products. By starting a drive motor, it can drive the linkage of worm gear, worm wheel, gear and rack, thereby realizing the movement of a fixed block in the slide. This method allows the welding auxiliary device to adapt to metal products of different lengths, ensuring that the two metal sections to be welded can fit together completely, providing a strong guarantee for high-quality metal product welding.

[0005] However, the welding auxiliary devices currently in use still have certain shortcomings. The auxiliary devices mentioned above can adapt to metal products of different lengths, but the fixing blocks for fixing the metal products are not easy to replace, and there are limitations on the types of metal products. Fixing other types of metal products will affect stability, thereby affecting the accuracy of welding. Therefore, it is necessary to improve the existing structure. Utility Model Content

[0006] The purpose of this invention is to provide an aluminum alloy welding auxiliary device with a precise docking and fixing structure, so as to solve the problem mentioned in the background art that the auxiliary device is unstable in fixing different types of welded parts, which affects the accuracy of welding docking.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy welding auxiliary device with a precise docking and fixing structure, comprising a base, a battery pack connected to the bottom of the base, three sets of fixing components connected to the upper surface of the base, and buttons connected to the sides of the fixing components.

[0008] The fixing assembly includes a movable block, a motor, and a bidirectional lead screw. A fixing plate is connected to the side of the movable block of the fixing assembly. Insert blocks are symmetrically fixed to the side of the fixing plate. A protruding column block is fixed to the side of the fixing plate near the insert block. The fixing assembly is provided with a fixing mechanism for replacing the fixing plate.

[0009] Furthermore, the fixing mechanism includes a through groove that extends through the movable block of the fixing component. A threaded cylinder is rotatably connected inside the through groove. Both the threaded cylinder and the through groove are slidably connected to the protruding block. A rotating ring is rotatably connected to the end of the threaded cylinder. Both the rotating ring and the side of the threaded cylinder have notches.

[0010] Furthermore, the upper surface of the base is symmetrically provided with sliding grooves, and two sliding rods are rotatably connected through the sliding grooves. The two sliding rods are symmetrically distributed from left to right. The top of the sliding rods is connected to a fixing component. The base is provided with a positioning mechanism to improve the welding efficiency of the welded parts.

[0011] Furthermore, the positioning mechanism includes a toothed plate connected inside a sliding groove, and a ratchet is rotatably connected to the side of the sliding rod near the gear, with a gear connected to the side of the ratchet.

[0012] Furthermore, the gear and the toothed plate form a meshing connection, and the sliding rod has a telescopic groove on its side, through which a positioning block is slidably connected.

[0013] Furthermore, a spring is provided for telescopic connection between the positioning block and the telescopic groove, and the positioning block and the ratchet form a positioning connection.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This aluminum alloy welding auxiliary device features a precise butt-joint fixing structure. During use, to improve the stability of the welded parts, the fixing plate needs to be replaced according to the type. The rotating threaded cylinder slides and contracts through the through-groove thread, driving the rotating ring away from the protruding part of the convex block. After aligning with the notch, the fixing plate is pulled, allowing the insert block and convex block to slide and disassemble. After replacement, the welded parts are clamped by the bidirectional screws of two sets of fixing components, improving clamping stability and thus enhancing the butt-joint welding stability.

[0016] 2. With a protruding block provided, the protruding block can be directly inserted into and pass through the inside of the threaded cylinder after the threaded cylinder has been rotated to the correct direction. Then, by slightly rotating the threaded cylinder, the protruding block can be squeezed and fixed in a threaded manner, which improves the efficiency of disassembling the protruding block and also ensures stability.

[0017] 3. A rotating ring is provided, which prevents friction when the threaded cylinder presses against the convex block, thereby increasing the pressing force of the threaded cylinder on the convex block and improving the stability of the fixing plate during installation.

[0018] 4. Equipped with a ratchet and a positioning block, the position of the fixed component can be quickly adjusted by extending and retracting the positioning block and rotating the ratchet, improving the efficiency of welding parts. Attached Figure Description

[0026] 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.

[0027] Example 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 4The present invention provides the following technical solution to address the problem of unstable fixing of auxiliary devices for different types of welded parts, which affects the accuracy of welding joints: a fixing mechanism is disclosed, comprising a base 1, a battery pack 2 connected to the bottom of the base 1, three sets of fixing components 3 connected to the upper surface of the base 1, and buttons 4 connected to the sides of the fixing components 3; the fixing components 3 include a movable block, a motor, and a bidirectional lead screw, a fixing plate 101 connected to the side of the movable block of the fixing components 3, and insert blocks 102 symmetrically fixed to the side of the fixing plate 101. A protruding block 103 is fixed to the side of the fixing plate 101 near the insert block 102. The fixing assembly 3 is provided with a fixing mechanism for replacing the fixing plate 101. The fixing mechanism includes a through groove 104 that is opened through the movable block of the fixing assembly 3. A threaded cylinder 105 is threadedly rotatably connected inside the through groove 104. The threaded cylinder 105 and the through groove 104 are both slidably connected to the protruding block 103. A rotating ring 106 is rotatably connected to the end of the threaded cylinder 105. Both the rotating ring 106 and the threaded cylinder 105 have notches on their sides.

[0028] When using the auxiliary device, to improve the stability of the welded parts, different fixing plates 101 need to be replaced according to the type of welded parts. The threaded cylinder 105 can be rotated and slide through the through groove 104 via a threaded path. Figure 4 As shown, when the threaded cylinder 105 slides, it can retract into the through groove 104. The retracted threaded cylinder 105 can drive the rotating ring 106 away from the protruding part on the side of the convex block 103. Then, the threaded cylinder 105 and the notch of the rotating ring 106 are aligned, and the notch is aligned with the protruding position of the rotating ring 106. Then, the fixing plate 101 is pulled outward, which can drive the insert block 102 and the convex block 103 to move. When the insert block 102 moves, it can slide through the movable block of the fixing component 3. When the convex block 103 moves, it can slide through the through groove 104, the rotating ring 106 and the inside of the threaded cylinder 105. When the convex block 103 slides out of the through groove 104, the fixing plate 101 can be disassembled and replaced. The replacement fixing plate 101 can squeeze and clamp the welded parts through the bidirectional screw of the fixing component 3. There are two sets of fixing components 3 for clamping, which improves the stability of the clamping of the fixing components 3, thereby improving the stability of the butt welding of the welded parts.

[0029] Example 2, as follows Figure 1 , Figure 5 and Figure 6The present invention provides the following technical solution to address the problem of low docking efficiency of auxiliary devices. Based on Embodiment 1, a positioning mechanism is disclosed: A sliding groove 201 is symmetrically provided on the upper surface of the base 1. Two sliding rods 202 are rotatably connected through the sliding groove 201, and the two sliding rods 202 are symmetrically distributed left and right. A fixing component 3 is connected to the top of the sliding rod 202. A positioning mechanism for improving the docking efficiency of welded parts is provided inside the base 1. The positioning mechanism includes a toothed plate 203 connected inside a sliding groove 201. A ratchet 204 is rotatably connected to the side of the sliding rod 202 near the gear 205. The gear 205 is connected to the side of the ratchet 204, and the gear 205 and the toothed plate 203 form a meshing connection. A telescopic groove 206 is provided on the side of the sliding rod 202. A positioning block 207 is slidably connected through the telescopic groove 206. A spring is telescopically connected between the positioning block 207 and the telescopic groove 206. The positioning block 207 and the ratchet 204 form a positioning connection.

[0030] Because the welded parts have different lengths, the positions of the two fixing components 3 need to be adjusted to improve their stability. One set of fixing components 3 can be moved towards the other. When the fixing components 3 move, they can drive the sliding rod 202 to move. When the sliding rod 202 moves, it can drive the gear 205 to mesh and rotate with the gear plate 203. Figure 6 As shown, when gear 205 meshes and rotates, it drives ratchet 204 to rotate on the side of sliding rod 202. When ratchet 204 rotates, the inclined surface of the meshing teeth can press against the side of positioning block 207. After being pressed, positioning block 207 can slide through telescopic groove 206. When positioning block 207 slides, it can press against spring. When positioning block 207 presses out of the side of ratchet 204, sliding rod 202 can slide inside sliding groove 201, realizing the adjustment of the distance between the two sets of fixing components 3. Since the two sets of fixing components 3 are relatively distributed, under the premise of fixing welded parts, such as Figure 1 and Figure 5 As shown, the positioning block 207 positions the ratchet 204 in one direction. When the ratchet 204 is positioned, the gear 205 is positioned through the toothed plate 203. Therefore, when the positioning block 207 is not operated, the distance between the two sets of fixed components 3 is stable and there will be no position movement. When it is necessary to move the welded parts, only the corresponding positioning block 207 needs to be operated, which improves the efficiency of the welded parts docking.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
