Description

Technical Field

[0001] This utility model belongs to the field of welding component fixing technology, specifically a welding component fixing device. Background Technology

[0002] In industries such as machinery manufacturing, pipe processing, and automotive parts production, welded components are key parts in the assembly and forming process of various products. The welding quality of welded components directly affects the structural strength, sealing performance, and service life of the final product. Therefore, precise positioning and secure fixing of welded components are crucial during welding operations. For circular weldments, proper fixation during welding is particularly crucial. Due to their shape, if not securely fixed, circular weldments are prone to rotation or displacement during welding due to factors such as arc force, workpiece weight, or external vibrations. This can lead to misalignment of the weld joint, uneven weld bead, and other problems, severely impacting weld quality. To avoid such issues, specialized fixing devices are typically used to position and secure the circular weldment. Currently, most common circular welding fixtures on the market are specialized structures designed for circular welding parts of specific sizes. In actual production, the same production scenario often requires handling circular welding parts of various diameters. Due to the limitations of their structural design, existing fixtures can only be used to fix circular welding parts of a single size or a limited range of sizes. When it is necessary to fix circular welding parts of different sizes, operators have to frequently change the corresponding fixtures. This not only increases the number of operation steps, extends auxiliary operation time, and reduces production efficiency, but may also lead to a decrease in positioning accuracy due to repeated replacements or adjustments of the fixtures, affecting the stability of welding quality. In addition, equipping multiple sets of specialized fixtures to accommodate welding parts of various sizes will also increase equipment procurement costs and storage space occupation, which is not conducive to the control of production costs and the rational utilization of production space.

[0003] Therefore, a welding component fixing device is proposed to address the above problems. Utility Model Content

[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] like Figures 1 to 5 As shown, this utility model provides a welding workpiece fixing device, including a welding table 1; The surface of the welding table 1 is equipped with an adapter fixing component 2. The adapter fixing component 2 includes a fixing frame 21 symmetrically arranged on the upper surface of the welding table 1, a limiting sleeve 22 installed in a groove on the surface of the fixing frame 21, and a disc frame 23, a sleeve block 24, a swing arm rod 25, a movable rod 26, a clamping plate 27, and a rotating adjustment component 28 for adapter fixing. The disc frame 23 is installed at one end of the limiting sleeve 22, the sleeve block 24 is hinged inside the disc frame 23, multiple movable rods 26 are installed on one side surface of the fixed frame 21, the swing arm rod 25 is rotatably connected to the surface of the movable rod 26, the sleeve block 24 is slidably connected to the surface of the swing arm rod 25, and the clamping plate 27 is installed at one end of the swing arm rod 25. The fixed frame 21, limiting sleeve 22, disc frame 23, sleeve block 24, swing arm rod 25, movable rod 26, clamping plate 27, and rotating adjustment component 28 in the adapter fixing assembly 2 work together to adjust the clamping state according to the diameter of the weldment, breaking the limitation of traditional devices that can only fix weldments of a single size and improving the versatility of the device.

[0018] Several rubber blocks are installed on the surface of the chuck 27. On the one hand, they can increase the friction between the chuck 27 and the workpiece, effectively preventing the workpiece from sliding during the welding process and ensuring the accuracy of the welding position. On the other hand, the rubber blocks have a certain degree of elasticity, which can avoid surface damage caused by hard contact between the chuck 27 and the workpiece, thus protecting the workpiece. This is especially suitable for processing round workpieces with high surface quality requirements.

[0019] The rotating adjustment component 28 includes a limiting plate 281 installed at the other end of the limiting sleeve 22. The limiting plate 281 is in contact with the fixing frame 21. A limiting plate 282 is installed on the surface of the plate frame 23. The limiting plate 282 is in contact with the fixing frame 21. A safety pin 283 is inserted into a through hole on the surface of the limiting plate 281. One end of the safety pin 283 passes through the limiting plate 281 and is inserted into a socket on the surface of the fixing frame 21. This allows the plate frame 23 to be quickly locked after the clamping plate 27 is adjusted to a suitable position, preventing accidental rotation during welding and ensuring the stability of the clamping state. At the same time, the insertion and removal of the safety pin 283 is simple, allowing the operator to adjust the position of the clamping plate 27 as needed, thus balancing the reliability of the fixation and the convenience of operation.

[0020] The surface of the fixing frame 21 has multiple insertion holes, which are arranged in a circular array around the center point of the fixing frame 21. This provides more insertion position options for the safety pin 283, allowing the rotation angle of the plate frame 23 to be flexibly adjusted according to the size of the weldment, further expanding the adaptability range of the device to circular weldments of different diameters.

[0021] The surface of the fixed frame 21 is equipped with a drive docking assembly 3. The drive docking assembly 3 includes a docking block 31 installed on the bottom surface of the fixed frame 21, a docking groove 32 opened on the surface of the welding table 1, a bidirectional lead screw 33 for driving, and a drive motor 34. The docking block 31 is slidably connected inside the docking groove 32. The bidirectional lead screw 33 is threadedly connected to the threaded hole on the surface of the docking block 31, and both ends of the bidirectional lead screw 33 pass through the docking block 31 and are rotatably connected inside the docking groove 32. The drive motor 34 is installed on one side surface of the welding table 1, and one end of the drive motor 34 passes through the welding table 1 and is connected to one end of the bidirectional lead screw 33. The docking block 31, docking groove 32, bidirectional lead screw 33 and drive motor 34 in the drive docking assembly 3 realize automatic docking of the weldment through mechanical drive, reduce the error of manual adjustment, improve docking accuracy and welding efficiency. The overall structure design is reasonable and takes into account both adaptability and operability.

[0022] A guide rod 35 is slidably connected in the through hole on the surface of the docking block 31. Both ends of the guide rod 35 pass through the docking block 31 and are installed inside the docking groove 32, which effectively prevents the docking block 31 from deflecting or getting stuck under the drive of the bidirectional lead screw 33.

[0023] Among them, the structure of drive motor 34 is existing technology, and its working principle is a well-known technology. The appropriate model is selected according to the actual use.

[0024] Working principle and process: First, adjust the adapter fixing component 2 to clamp the weldment. Place the circular weldment inside the limiting sleeve 22. According to the diameter of the circular weldment, pull out the safety pin 283. Then rotate the limiting plate 281. Since the limiting plate 281 and the plate frame 23 are connected through the limiting sleeve 22, the plate frame 23 will rotate accordingly. When the plate frame 23 rotates, the hinged sleeve block 24 inside it will slide on the surface of the swing arm 25. At the same time, the swing arm 25 will rotate around the movable rod 26, thereby changing the clamping position. The opening and closing degree between the discs 27: When the clamping disc 27 is adjusted to a position that can fit against the surface of the circular weldment, the rotation of the limiting disc 281 is stopped, the safety pin 283 is inserted into the through hole of the limiting disc 281 and one end of it is inserted into the corresponding insertion hole on the surface of the fixing frame 21, thus completing the fixation of the disc frame 23 position. At this time, the clamping disc 27 firmly clamps the circular weldment under the action of the swing arm 25, and the rubber block on the surface of the clamping disc 27 can increase the friction between it and the weldment, prevent the weldment from sliding, and avoid damaging the surface of the weldment. This fixing process is simple to operate and can be completed simply by rotating the limit plate 281. There are no excessive steps required to fix the weldment, which greatly improves the operation effect. After the circular weldment is fitted and clamped, the docking operation is performed. The drive motor 34 is started, and the drive motor 34 drives the bidirectional lead screw 33 to rotate in the docking groove 32. Since the docking block 31 is threadedly connected to the bidirectional lead screw 33 and the docking block 31 is slidably connected in the docking groove 32, and under the guidance of the guide rod 35, the two docking blocks 31 will move relatively closer along the docking groove 32, thereby driving the fixing frame 21 to move synchronously, so that the two clamped circular weldments gradually approach each other and complete the docking, so as to meet the docking position requirements during welding. After welding is completed, reverse the above steps, loosen the clamp 27 to fix the circular weldment, and then remove the welded weldment.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
