Description

Technical Field

[0001] This utility model relates to the field of arc welding operation technology, and in particular to a welding fixture for arc welding. Background Technology

[0002] In traditional arc welding operations, slag spatter has always been a significant factor affecting welding quality and the working environment. Most existing welding fixtures only have simple clamping functions and cannot effectively solve the problem of slag collection, resulting in a harsh working environment and cumbersome subsequent cleaning work. Conventional slag treatment methods mainly rely on manual cleaning or independently installed dust collection devices, which have problems such as inconvenient operation and low collection efficiency. For the mixed situation of ferrous and non-ferrous slag, a single adsorption method is often difficult to achieve comprehensive collection.

[0003] As per authorization announcement number CN222429540U, a welding fixture for arc welding relates to the field of welding auxiliary equipment technology. It includes a base plate with an adjustment groove on its upper side. An adjustment assembly is slidably installed within the adjustment groove. The adjustment assembly includes two adjustment blocks slidably installed within the adjustment groove. A clamping mechanism is installed on the upper side of each of the two adjustment blocks. A drive hole is provided on one side of the base plate, and an adjusting threaded rod is rotatably installed within the drive hole. This invention clamps and adjusts two materials to be welded using a clamping mechanism. A drive motor then rotates the adjusting threaded rod, causing the two adjustment blocks to move closer together, bringing the two welding materials into contact. Finally, welding is performed on these materials. This achieves the effect of clamping and holding irregularly shaped welding materials, thus improving the applicability of the device.

[0004] The welding fixture disclosed above for arc welding cannot effectively solve the problem of slag collection during use. The slag treatment mainly relies on manual cleaning or independently set dust collection devices, which has problems such as inconvenient operation and low collection efficiency.

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.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] This utility model provides a welding fixture for arc welding, such as... Figures 1-5As shown, the assembly includes: a mounting plate 1, a vacuum cleaner 2, a slide rail 3, a bidirectional threaded shaft 4, a motor 6, a movable slide rail 5, an adjustable slag removal assembly 7, and a clamping plate 8. The mounting plate 1 serves as the basic support structure. The vacuum cleaner 2 is fixedly mounted on one side of the mounting plate 1 to provide suction force. The slide rail 3 is formed on the mounting plate 1, and the bidirectional threaded shaft 4 is rotatably mounted inside the slide rail 3. The motor 6 is fixedly mounted on one end of the mounting plate 1, and its output end is connected to the bidirectional threaded shaft 4 to drive its rotation. There are two movable slide rails 5, which are respectively connected to the two sections of the bidirectional threaded shaft 4 via threads. The adjustable slag removal component 7 is mounted on a mounting bracket 701 fixedly connected to the output end of the movable slide rail 5 and connected to the output end of the vacuum cleaner 2. The clamping plate 8 is connected to the movable slide rail 5 and used to clamp the workpiece. The motor 6 drives the bidirectional threaded shaft 4 to rotate, causing the two movable slide rails 5 to move synchronously towards or away from each other, thereby adjusting the spacing of the clamping plates 8 to achieve workpiece clamping and positioning, and simultaneously adjusting the position of the adjustable slag removal component 7. This structural design constructs an integrated and collaborative welding fixture system. The mounting plate 1 serves as a foundation, providing stable support for each component and ensuring the stability of the overall structure. The vacuum cleaner 2 provides suction force, providing power for slag collection. The cooperation between the bidirectional threaded shaft 4 and the movable slide rail 5, driven by the motor 6, enables the movable slide rails 5 to move synchronously towards or away from each other, allowing the clamping plate 8 to precisely adjust its spacing, facilitating the clamping and positioning of workpieces of different sizes. Simultaneously, the adjustable slag removal component 7 can also move synchronously to the appropriate position for better slag collection from the welding area.

[0027] In a preferred embodiment, the adjustable slag removal assembly 7 includes: an adjusting frame, a clamping plate 702, a screw 704, a handwheel 706, a mounting base 705, a slag suction head 707, a rotating shaft 710, a square magnet 708, an input pipe 709, a worm gear 713, and a worm 712. One end of the adjusting frame is fixedly connected to the output end of the movable slide rail 5. The clamping plate 702 is installed at the other end of the adjusting frame. The lower surface of the clamping plate 702 is provided with a first elastic flame-retardant material layer. The screw 704 is threadedly connected to the clamping plate 702. The handwheel 706 is fixedly installed at one end of the screw 704. The mounting base 705 is rotatably installed at the other end of the screw 704 via a bearing 711. The slag suction head 707 is rotatably installed on the mounting base 705. The square magnet 708... Mounted on the slag suction head 707, this adjustable slag removal assembly is used to adsorb ferrous welding slag. One end of the input pipe 709 is connected to the slag suction head 707, and the other end is fixedly connected to the output end of the vacuum cleaner 2. A rotating shaft 710 is fixedly mounted on the slag suction head 707 and rotatably mounted inside the mounting base 705. A worm gear 713 is fixedly mounted on the rotating shaft 710, and a worm 712 is rotatably mounted on the mounting base 705 and meshes with the worm gear 713. Rotating the handwheel 706 drives the screw 704 to rotate, adjusting the height of the mounting base 705 and the slag suction head 707. Rotating the worm 712, through the worm gear 713 and the rotating shaft 710, drives the slag suction head 707 to adjust its angle. This adjustable slag removal assembly 7 achieves multi-dimensional flexible adjustment of height and angle. By rotating the handwheel 706, the screw 704 rotates, causing the mounting base 705 to move up and down, thereby adjusting the height of the slag suction head 707 so that it can better approach the welding point to collect welding slag. By utilizing the meshing of the worm gear 712 and the worm wheel 713, rotating the worm gear 712 drives the rotating shaft 710 and the slag suction head 707 to adjust their angles. This ensures that regardless of changes in the welding position and angle, the slag suction head 707 can be adjusted to the optimal collection angle, greatly improving the targeting and efficiency of slag collection. The first elastic flame-retardant material layer acts as a buffer when pressing the workpiece, while also possessing flame-retardant properties to ensure welding safety.

[0028] In a preferred embodiment, the input pipe 709 is made of a corrugated metal material, which has good flexibility and pressure resistance. During the height and angle adjustment of the suction head 707, the input pipe 709 can flexibly deform as the suction head 707 moves, without affecting the internal airflow channel due to bending. This ensures that the negative pressure suction generated by the vacuum cleaner 2 can be stably transmitted, thereby guaranteeing continuous and efficient suction of non-ferrous welding slag and welding fumes.

[0029] In a preferred embodiment, the first elastic flame-retardant material layer is a first memory foam 703. The first memory foam 703, as the first elastic flame-retardant material layer, possesses elasticity and memory properties. When pressing the workpiece, it can closely conform to the workpiece surface, providing uniform and stable pressure, ensuring that the workpiece does not shift during welding and adapting to the surfaces of workpieces of different shapes. Simultaneously, its flame-retardant properties effectively prevent sparks generated during welding from igniting surrounding materials, improving the safety of the tooling fixture during welding operations.

[0030] In a preferred embodiment, the surface of the clamping plate 8 is provided with a second elastic flame-retardant material layer for protecting the workpiece surface. This second elastic flame-retardant material layer on the surface of the clamping plate 8 can buffer the clamping force when clamping the workpiece, preventing excessive clamping from causing scratches or damage to the workpiece surface and ensuring the appearance quality of the workpiece. Furthermore, its flame-retardant properties can effectively prevent accidental burns to the workpiece surface from welding sparks, further improving the protection effect on the workpiece.

[0031] In a preferred embodiment, the second elastic flame-retardant material layer is a second memory foam 9. As the second elastic flame-retardant material layer, the second memory foam 9 not only possesses good elasticity, automatically adapting to the surface shape of the workpiece and applying appropriate clamping pressure, but also has memory properties, restoring its original shape after multiple clamping cycles, thus maintaining a stable protective and clamping effect. Its flame-retardant properties further ensure the safety of the workpiece during welding operations, preventing damage from flying sparks.

[0032] In a preferred embodiment, the movable slide rail 5 and the clamping plate 8 are fixedly connected. The movement of the movable slide rail 5 directly drives the movement of the clamping plate 8, and the fixed connection between the movable slide rail 5 and the clamping plate 8 ensures the synchronicity of their movements. When the motor 6 drives the bidirectional threaded shaft 4 to move the movable slide rail 5, the clamping plate 8 can accurately follow the movement, making the clamping and positioning of the workpiece more precise and reliable. There is no offset or jamming caused by connection problems, which effectively improves the stability and accuracy of the tooling fixture in workpiece clamping and positioning.

[0033] The method of using this welding fixture for arc welding is as follows:

[0034] Preparation stage

[0035] Install the workpiece: Place the workpiece to be arc welded on the mounting plate 1.

[0036] Adjusting the spacing of the clamping plates 8: Start the motor 6, which drives the bidirectional threaded shaft 4 to rotate. Since the movable slide rails 5 are connected to the two reverse threads of the bidirectional threaded shaft 4 via threads and are slidably engaged in the slide groove 3, when the bidirectional threaded shaft 4 rotates, it drives the two movable slide rails 5 to move synchronously in opposite directions. The spacing of the clamping plates 8 connected to the movable slide rails 5 decreases accordingly, gently clamping the workpiece. If it is necessary to loosen or adjust the workpiece position, the motor 6 can drive the bidirectional threaded shaft 4 to reverse, causing the two movable slide rails 5 to move synchronously in opposite directions, increasing the spacing of the clamping plates 8. During this process, the second memory foam 9 on the clamping plates 8 makes flexible contact with the workpiece surface, preventing damage to the workpiece surface while ensuring sufficient clamping force to fix the workpiece.

[0037] Adjusting the position of the adjustable slag removal component 7: After adjusting the spacing of the clamping plates 8, the adjustable slag removal component 7 moves synchronously to the corresponding position with the moving slide rail 5, but further fine-tuning of its height may be necessary. Turning the handwheel 706 causes the screw 704 to rotate. Since the screw 704 is threadedly connected to the clamping plate 702, and the mounting base 705 is rotatably mounted on the other end of the screw 704 through the bearing 711, the rotation of the screw 704 causes the mounting base 705 to move along the axis of the screw 704, thereby adjusting the height of the mounting base 705 and the slag suction head 707 so that the slag suction head 707 is as close as possible to the welding part.

[0038] Adjusting the angle of the slag suction head 707: According to the requirements of the welding position and angle, rotate the worm 712 on the mounting base 705. The worm 712 meshes with the worm wheel 713. The worm wheel 713 is fixedly installed on the rotating shaft 710. The rotating shaft 710 is fixedly connected to the slag suction head 707. Therefore, the rotation of the worm 712 drives the worm wheel 713, the rotating shaft 710 and the slag suction head 707 to adjust the angle, so that the slag suction head 707 is aligned with the direction in which welding slag may be generated during welding.

[0039] Welding stage

[0040] After completing the above preparations, arc welding can begin. During the welding process, weld slag is generated.

[0041] Iron slag collection: The square magnet 708 set on the slag suction head 707 plays a role in adsorbing the splashed iron slag and reducing the scattering of iron slag in the working area.

[0042] Collection of Non-Ferrous Welding Slag and Fumes: When vacuum cleaner 2 is turned on, it generates a negative pressure airflow through an input pipe 709 made of corrugated metal material. Since one end of the input pipe 709 is connected to the slag suction head 707 and the other end is fixedly connected to the output end of vacuum cleaner 2, this negative pressure airflow draws non-magnetic welding slag and welding fumes into vacuum cleaner 2 through the suction head 707 and the input pipe 709. The corrugated metal input pipe 709 maintains good sealing and airflow transmission even when the position and angle of the suction head 707 are adjusted, ensuring continuous and efficient collection of non-ferrous welding slag and welding fumes.

[0043] After welding

[0044] After welding is completed, turn off motor 6 and vacuum cleaner 2. To remove the workpiece, restart motor 6 to drive the bidirectional threaded shaft 4 to rotate, causing the two moving slide rails 5 to move in opposite directions, widening the gap between clamping plates 8, and smoothly removing the workpiece. If the tooling fixture needs cleaning or other maintenance, perform the corresponding operations as needed, such as cleaning the iron welding slag adsorbed on the slag suction head 707, checking the connection of the input pipe 709, etc.

[0045] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
