Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically a dual-station alternating feeding welding device. Background Technology

[0002] Welding is a common joining process in the fields of machinery manufacturing and metal processing, and it is widely used in the production of various metal structural parts and components. In actual production, many workpieces need to be fixed by fixtures before welding to ensure the accuracy of the welding position and the stability of the welding quality. Therefore, welding fixtures or welding jigs are usually set up to position and clamp the workpieces before welding operations are carried out.

[0003] However, existing welding equipment typically employs a single-station structure, where operators complete a series of operations such as workpiece placement, positioning, clamping, and welding at the same station. When a workpiece enters the welding stage, the operator cannot simultaneously perform the clamping of the next workpiece and must wait for welding to be completed before proceeding with the next clamping operation. This results in the welding equipment being in a waiting state during the clamping process, leading to low equipment utilization and limited overall production efficiency. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a dual-station alternating feeding welding device, which solves the problem of low efficiency caused by the inability to perform clamping and welding simultaneously in existing welding devices with single-station operation.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: A dual-station alternating feeding welding device includes: a table frame, on which an alternating feeding mechanism is provided, the alternating feeding mechanism including a clamping mechanism one and a clamping mechanism two, a slide rail on the table frame, both clamping mechanisms one and two slidably mounted on the slide rail, a moving cylinder one installed on the table frame, the output end of the moving cylinder one connected to clamping mechanism one for driving clamping mechanism one to move along the slide rail, and a moving cylinder two installed on the table frame, the output end of the moving cylinder two connected to clamping mechanism two for driving clamping mechanism two to move along the slide rail; clamping mechanisms one and two have the same structure and both include a base, a clamping fixed jaw is provided on the base, a positioning block is provided on the clamping fixed jaw, and a clamping cylinder is also installed on the base, the clamping cylinder driving the clamping jaw to move towards the clamping fixed jaw to clamp the workpiece.

[0006] Preferably, the slide rail is fixed on the table frame, and multiple slide rails are provided. The slide rail is used to guide the movement of clamping mechanism one and clamping mechanism two.

[0007] Preferably, a fixing block is fixedly connected to the base, and the clamping jaws pass through the fixing block.

[0011] Preferably, a welding clamping cylinder is installed on the clamping jaws for auxiliary clamping of welding workpieces.

[0012] Preferably, both the first movable cylinder and the second movable cylinder are fixedly mounted on the table frame, and the piston rods of the first movable cylinder and the second movable cylinder are fixedly connected to the bases of the first clamping mechanism and the second clamping mechanism, respectively.

[0013] Preferably, the clamping mechanism one and the clamping mechanism two are located between the welding station and the clamping station, respectively, and are driven alternately by the moving cylinder one and the moving cylinder two.

[0014] (III) Beneficial Effects Compared with the prior art, the present invention provides a dual-station alternating feeding welding device, which has the following beneficial effects: 1. This dual-station alternating feeding welding device utilizes a slide rail on a table frame and two sets of clamping mechanisms that can move on the slide rail, driven by a moving cylinder, so that the two sets of clamping mechanisms can move alternately between the clamping station and the welding station. While one set of clamping mechanisms is performing welding operations, the other set of clamping mechanisms can clamp the workpiece, thereby realizing simultaneous clamping and welding, reducing equipment waiting time, improving equipment utilization, and effectively improving overall welding production efficiency.

[0015] 2. This dual-station alternating feeding welding device utilizes a clamping jaw, a clamping jaw, and a clamping cylinder mounted on a base. The clamping cylinder drives the clamping jaw to move towards the clamping jaw to achieve stable clamping of the workpiece. In conjunction with the positioning block, the workpiece is positioned, enabling the workpiece to be quickly and accurately placed in the predetermined position during the clamping process. This improves workpiece clamping efficiency, avoids positional deviation during welding, and enhances welding position accuracy and welding quality stability.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-2A dual-station alternating feeding welding device includes: a table frame 1, an alternating feeding mechanism 3 mounted on the table frame 1, the alternating feeding mechanism 3 including a clamping mechanism 1 31 and a clamping mechanism 2 32, a slide rail 2 mounted on the table frame 1, the clamping mechanism 1 31 and the clamping mechanism 2 32 being slidably mounted on the slide rail 2, a moving cylinder 1 33 mounted on the table frame 1, the output end of the moving cylinder 1 33 being connected to the clamping mechanism 1 31 for driving the clamping mechanism 1 31 to move along the slide rail 2, and a moving cylinder 2 34 mounted on the table frame 1, the output end of the moving cylinder 2 34 being connected to the clamping mechanism 2 32 for driving the clamping mechanism 2 32 to move along the slide rail 2, thereby causing the clamping mechanism 1 31 to move along the slide rail 2, thus causing the clamping mechanism 1 31 to move along the slide rail 2, thereby ... The clamping mechanism 31 and clamping mechanism 32 move alternately to the welding station to achieve alternating clamping and welding. The clamping mechanism 31 and clamping mechanism 32 have the same structure and both include a base 4. The base 4 is provided with a clamping fixed jaw 6 and a positioning block 7. The base 4 is also equipped with a clamping cylinder 12. The clamping cylinder 12 drives the clamping jaw 11 to move towards the clamping fixed jaw 6 to clamp the workpiece. By setting a slide rail 2 on the table 1, a stable linear movement guide can be provided for the clamping mechanism 31 and clamping mechanism 32, so that the two clamping mechanisms can move smoothly on the table 1 in a predetermined direction, thereby ensuring the accuracy of the loading and welding positions. Movable cylinders 33 and 34 drive clamping mechanisms 31 and 32 to move along slide rail 2, respectively, enabling them to reciprocate between the clamping station and the welding station. When one clamping mechanism is in the welding station performing welding operations, the other clamping mechanism can simultaneously clamp the workpiece, thus achieving alternating loading operations at two stations, effectively reducing equipment waiting time and improving equipment utilization and welding efficiency. Simultaneously, by setting a fixed clamping jaw 6 and a cooperating clamping jaw 11 on the base 4, and providing driving force from the clamping cylinder 12, the clamping jaw 11 can move towards the fixed clamping jaw 6 to clamp the workpiece, thereby achieving stable clamping of the workpiece to be welded. A positioning block 7 is set on the fixed clamping jaw 6, providing a reliable positioning reference for the workpiece and limiting its positional deviation during clamping, thereby improving the accuracy of the workpiece welding position and solving the problem of unstable welding quality caused by inaccurate positioning in existing technologies.

[0021] The slide rail 2 is fixed on the table frame 1. Multiple slide rails 2 are provided to guide the movement of clamping mechanism 1 31 and clamping mechanism 2 32. By setting multiple slide rails 2 on the table frame 1, a stable linear guide structure is formed, ensuring good parallelism and stability of clamping mechanism 1 31 and clamping mechanism 2 32 during movement. This prevents workpiece positioning accuracy from being affected by shaking or offset during movement. Simultaneously, the multiple slide rails 2 structure improves overall support rigidity, further enhancing the operational reliability of the device. A fixing block 5 is fixedly connected to the base 4. The clamping jaw 6 is mounted on the base 4 via the fixing block 5. By setting the fixing block 5 as the mounting structure for the clamping jaw 6, the clamping jaw 6 can be securely mounted on the base 4, allowing it to withstand the clamping force from the clamping cylinder 12 during clamping without displacement or loosening. This structure also facilitates the disassembly and replacement of the clamping jaw 6 to adapt to the clamping requirements of different types of workpieces, thereby improving the applicability of the device.

[0022] The positioning block 7 is fixedly mounted on the clamping jaw 6 and is used to position the workpiece to be welded. By setting the positioning block 7 on the clamping jaw 6, a clear positioning reference can be provided for the workpiece when it is placed, so that the workpiece can be quickly placed in the correct position, thereby avoiding positional deviations caused during manual clamping, ensuring the consistency of the welding position, and improving the stability of welding quality. A cylinder fixing seat 9 is set on the base 4, and the clamping cylinder 12 is mounted on the base 4 through the cylinder fixing seat 9. By setting the cylinder fixing seat 9, a stable installation position can be provided for the clamping cylinder 12, so that the clamping cylinder 12 can be firmly fixed on the base 4, thereby ensuring that the clamping cylinder 12 can stably output driving force during operation, ensuring that the clamping jaw 11 can reliably clamp the workpiece, and improving the stability and reliability of the clamping cylinder 12.

[0023] A guide post 10 is slidably connected to the cylinder mounting base 9. The guide post 10 is fixedly connected to the end of the clamping jaw 11 away from the clamping fixed jaw 6. By setting the guide post 10, the movement direction of the clamping jaw 11 can be guided, so that the clamping jaw 11 moves linearly along a fixed direction under the drive of the clamping cylinder 12, thereby avoiding swaying or tilting during the clamping process, improving the stability of the clamping process, and ensuring that the clamping force can be evenly applied to the workpiece.

[0024] A welding clamping cylinder 8 is installed on the clamping jaw 6 to assist in clamping welding workpieces. By setting the welding clamping cylinder 8 on the clamping jaw 6, the workpiece can be additionally clamped when welding is required. This makes the device suitable not only for welding straight plate workpieces, but also for clamping workpieces that require welding or lap welding, thus improving the versatility and applicability of the device.

[0025] Both movable cylinder 33 and movable cylinder 34 are fixedly mounted on the table frame 1. The piston rods of movable cylinder 33 and movable cylinder 34 are fixedly connected to the base 4 of clamping mechanism 31 and clamping mechanism 32, respectively, to drive the base 4 to reciprocate along the slide rail 2. By fixing movable cylinder 33 and movable cylinder 34 on the table frame 1 and fixing their piston rods to the base 4, the linear driving force of movable cylinder 33 and movable cylinder 34 can be directly transmitted to the base 4, thereby driving clamping mechanism 31 and clamping mechanism 32 to reciprocate along the slide rail 2, realizing the rapid movement of clamping mechanism 31 and clamping mechanism 32 between different workstations.

[0026] Clamping mechanism 1 31 and clamping mechanism 2 32 are located between the welding station and the clamping station, respectively. Through the alternating drive of moving cylinder 1 33 and moving cylinder 2 34, clamping mechanism 1 31 and clamping mechanism 2 32 are switched back and forth between the welding station and the clamping station, thereby realizing the alternation of workpiece clamping and welding. In actual operation, when clamping mechanism 1 31 moves to the welding station for welding, clamping mechanism 2 32 is in the clamping station for the operator to place new workpieces to be welded. After welding is completed, the positions of clamping mechanism 1 31 and clamping mechanism 2 32 are exchanged by moving cylinder 1 33 and moving cylinder 2 34, so that the new workpiece enters the welding station to continue welding, thereby realizing continuous alternating welding operations, effectively reducing the waiting time of welding equipment and improving production efficiency.

[0027] In summary, this dual-station alternating feeding welding device is used by installing the entire device in the work area and arranging the welding equipment at the corresponding welding station positions. The device uses a table frame 1 as the overall support base, and a slide rail 2 is fixedly installed on the table frame 1. The slide rail 2 provides linear movement guidance for clamping mechanism 1 31 and clamping mechanism 2 32, allowing them to slide smoothly along the slide rail 2 on the table frame 1. They are then driven by moving cylinders 1 33 and 2 34 installed on the table frame 1. The piston rod of moving cylinder 1 33 is fixedly connected to the base 4 of clamping mechanism 1 31, and the piston rod of moving cylinder 2 34 is fixedly connected to the base 4 of clamping mechanism 2 32. When the first moving cylinder 33 is activated, its piston rod pushes the base 4 to move along the slide rail 2, thereby moving the clamping mechanism 31 to the welding position. Meanwhile, the second moving cylinder 34 remains in the other position, keeping the clamping mechanism 32 in the clamping position. The operator places the workpiece to be welded on the clamping mechanism 32. The workpiece first contacts the positioning block 7 on the clamping jaw 6, which limits and positions the workpiece, allowing it to be quickly placed in the predetermined position, thus improving clamping efficiency and ensuring the accuracy of the workpiece position. After the workpiece is positioned, the clamping cylinder 12 mounted on the base 4 begins to operate. The clamping cylinder 12 is activated by the cylinder fixing seat 9. Fixed on the base 4 and outputting linear driving force, the clamping jaw 11 moves towards the clamping fixed jaw 6. During the movement, the guide post 10 slides on the cylinder fixing seat 9, thereby guiding the movement direction of the clamping jaw 11, enabling the clamping jaw 11 to move along a stable linear direction and gradually press the workpiece between the clamping fixed jaw 6 and the clamping jaw 11, achieving stable clamping of the workpiece. When insert welding or special structure welding is required, the insert welding clamping cylinder 8 installed on the clamping fixed jaw 6 can further assist in clamping the workpiece, thereby enhancing the fixing effect of the workpiece and preventing the workpiece from loosening or shifting during the welding process. While the second clamping mechanism 32 completes the workpiece clamping, the first clamping mechanism 31 performs welding... After the welding operation is completed at the receiving station, the first movable cylinder 33 retracts, driving the first clamping mechanism 31 to return to the clamping station along the slide rail 2. At the same time, the second movable cylinder 34 extends, driving the second clamping mechanism 32 to move along the slide rail 2 to the welding station, allowing the clamped workpiece to enter the welding area for welding. In this way, through the alternating drive of the first movable cylinder 33 and the second movable cylinder 34, the first clamping mechanism 31 and the second clamping mechanism 32 are cyclically switched between the welding station and the clamping station, so that when one clamping mechanism is welding, the other clamps the workpiece, thus forming a continuous alternating production process, effectively reducing the waiting time of welding equipment, improving equipment utilization, and improving the overall welding production efficiency.
