[0022] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0023] 1. The present invention realizes the automatic flipping and double-sided welding of the workpiece through the coordinated work of the support frame, welding mechanism, workbench assembly, mobile flip assembly and retractable limit assembly, improves welding efficiency and welding quality, reduces labor intensity and safety risks. At the same time, the flexibility of the equipment is also significantly improved, and it can adapt to workpieces of different sizes and shapes.

[0024] 2. The present invention adopts the design of a mobile flip assembly. After the first electric slide rail receives a start signal, it starts to operate and provides power to slide the first electric slider on the slide rail along the X-axis direction. The sliding motion of the first electric slider directly drives the first sliding seat connected to it to move along the X-axis direction. The movement of the first sliding seat is transmitted to the rotating shaft through the bearing seat. Due to the design of the bearing seat, the rotating shaft can rotate relative to the first sliding seat. When the first sliding seat (and the connected rotating shaft and transmission gear) attempts to move along the X-axis direction, the transmission gear will roll on the rack due to the meshing action of the rack and the gear. The rolling motion of the transmission gear causes it to rotate, and then the translational motion is converted into rotational motion around its axis through the rotating shaft. The rotation of the transmission gear is transmitted to the placement rack through the rotating shaft, so that the placement rack rotates 180 degrees around its axis together with the rotating shaft. In this way, the placement rack and the workpiece are moved and flipped along the X-axis, providing a mobile flip assembly with a compact structure, precise and controllable motion, and high transmission efficiency.

[0025] 3. The present invention can realize accurate positioning of the placement rack at different positions through the cooperation of the limit seat and the retractable limit assembly. This design improves the positioning accuracy and stability of the entire mobile flip assembly. The close cooperation between the limit plate and the groove effectively limits the movement range of the placement rack, preventing the placement rack from excessive movement or flipping due to accidental or misoperation, thereby enhancing the safety of the system.

[0026] 4. The present invention can quickly clamp and release the workpiece by setting a fixed fixture, thereby improving the efficiency of the welding operation. At the same time, through the cooperation of the C-shaped limit enclosure and the horizontal support plate, the workpiece can be stably clamped to prevent the workpiece from moving or shaking in the horizontal direction during the welding process.

[0027] 5. The present invention uses the pressing assembly to abut and fix the top of the workpiece, further enhancing the stability of the workpiece during welding and preventing movement and warping. The design of the rotating seat allows the L-shaped frame to rotate within a certain range, so that the pressing assembly can adapt to workpieces of different shapes or positions. The position of the abutment seat can be adjusted by manually rotating the operating handle, which is simple and quick to operate.

[0028] 6. The present invention realizes a high degree of automation and intelligence in the welding system through the comprehensive control and management of the central controller. This not only improves the efficiency and accuracy of the welding operation, but also greatly reduces the burden on the operator. The introduction of the camera device provides real-time visual feedback for the welding process. The central controller can fine-tune the position and posture of the welding head according to the real-time image information to ensure the welding quality.

[0029] 7. The dust suction component of the present invention sucks the welding slag and dust generated in the welding area through the dust suction pipe and transmits it to the external vacuum cleaner for treatment. The suction force of the dust suction component can be adjusted according to the size of the welding area and the amount of welding slag generated to ensure the dust suction effect. The welding head and the dust suction component are respectively located on opposite sides of the lifting seat. This layout ensures that the welding operation and the dust suction operation can be carried out at the same time without interfering with each other. The welding head is responsible for performing the welding task, while the dust suction component is responsible for timely removing the welding slag and dust generated during the welding process to keep the welding area clean.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0052] Please refer to Figure 1-8 As shown, the embodiment provides a welding machine with a fixing fixture, including a support frame 10 and a welding mechanism, the welding mechanism including a gantry 21 mounted on the support frame 10, an X-axis driving assembly 22 and a welding assembly 23 mounted on the gantry 21; the X-axis driving assembly 22 is used to drive the gantry 21 to move along the X-axis direction of the base, and the welding assembly 23 is used to weld the workpiece; and further includes:

[0053] The workpiece fixing assembly includes a placing frame 31 and a fixing fixture 32. The placing frame 31 is flippably mounted on the supporting frame 10. The fixing fixture 32 is mounted on the placing frame 31. The fixing fixture 32 is used to fix the two workpieces at a preset position.

[0054] A mobile flip assembly 40, which is mounted on the support frame 10, and is used to drive the placement frame 31 to move along the X-axis direction and flip 180 degrees, so that the placement frame 31 can switch between a first position with the front side facing upward and a second position with the back side facing upward;

[0055] Two retractable limit assemblies 50 are respectively installed on the support frame 10 and are respectively located below the first position and the second position. The retractable limit assemblies 50 can be extended or retracted in the vertical direction to restrict or release the flipping of the placement rack 31.

[0056] On the basis of the above structure, during the working process, the two workpieces to be welded are first placed in the fixing fixture 32 on the placement rack 31 in the first position, and the workpieces are firmly fixed in the preset position by adjusting the fixing fixture 32. According to the welding requirements, the position of the gantry 21 is adjusted by the X-axis drive assembly 22, so that the welding assembly 23 is aligned with the front welding parts of the two workpieces, the welding machine is started, and the welding assembly 23 starts to work and welds the welding parts. During the welding process, the retractable limit assembly 50 in the first position remains in an extended state, and the placement rack 31 is limited to ensure the stability of the welding process. After the welding is completed, the welding assembly 23 stops working. If the welding of the next side is required, the mobile flip assembly 40 is started, and the placement rack 31 is moved and flipped 180 degrees along the X-axis direction, so that the placement rack 31 is in the second position. During the welding process, the retractable limit assembly 50 in the second position remains in an extended state, and the placement rack 31 is limited to ensure the stability of the welding process. Repeat the welding process, and after all the welding is completed, turn off the welding machine, take the workpiece out of the fixing fixture 32, and proceed to the next step. In this way, the present invention realizes the rapid clamping and automatic flipping of the workpiece through the design of the mobile flipping mechanism and the fixed fixture 32, greatly improving the welding efficiency; at the same time, during the flipping process, the mobile flipping assembly 40 can ensure that the placement rack 31 and the workpiece thereon maintain a safe distance from the welding mechanism or other equipment located above it by moving along the X-axis. This movement effectively avoids collisions caused by improper position during the flipping process, protects the welding mechanism and the workpiece from damage, and by moving along the X-axis, the mobile flipping assembly 40 can better cooperate with other equipment or workstations to form a smooth production line. The fixed fixture 32 ensures the stability and accuracy of the workpiece during the welding process, prevents displacement or deformation during the welding process, and thus ensures the consistency of welding quality. The design of the automated mobile flipping mechanism reduces manual intervention, reduces labor intensity and safety risks, and makes welding operations easier and more efficient. The retractable limiting assembly 50 remains in an extended state during the welding process, and limits the placement rack 31, ensuring the stability of the welding process and preventing the placement rack 31 from losing control due to unexpected situations; the retractable design makes the equipment more flexible, and can adapt to workpieces of different sizes and shapes, thereby improving the versatility of the welding machine. In summary, the present invention realizes automatic flipping and double-sided welding of the workpiece through the coordinated work of the support frame 10, the welding mechanism, the workbench assembly, the mobile flip assembly 40 and the retractable limiting assembly 50, thereby improving welding efficiency and welding quality, and reducing labor intensity and safety risks. At the same time, the flexibility of the equipment has also been significantly improved, and it can adapt to workpieces of different sizes and shapes.

[0057] In a preferred embodiment, the mobile flipping assembly 40 includes two first electric slide rails 41, two first electric sliders 42, two first sliding seats 43, two bearing seats 44, two rotating shafts 45, L-shaped mounting seats 46, a transmission rack 47 and a transmission gear 48; the two first electric slide rails 41 are symmetrically installed on both sides of the top of the support frame 10; the two first electric sliders 42 are respectively slidably installed on the two first electric slide rails 41; the two first sliding seats 43 are respectively installed on the two first electric sliders 42; one end of the two rotating shafts 45 is respectively fixedly connected to the two side walls of the placement frame 31, and the other end of the two rotating shafts 45 is respectively rotatably connected to the two first sliding seats 43 through a bearing seat 44; the L-shaped mounting seat 46 is installed on the inner side wall of the support frame 10; the transmission rack 47 is installed on the L-shaped mounting seat 46; the transmission gear 48 is fixedly installed on the rotating shaft 45 on the same side as the L-shaped mounting seat 46, and the transmission gear 48 and the transmission rack 47 are meshed with each other.

[0058] On the basis of the above structure, after receiving the start signal, the first electric slide rail 41 starts to operate, providing power to make the first electric slider 42 slide along the X-axis direction on the slide rail. The sliding motion of the first electric slider 42 directly drives the first sliding seat 43 connected thereto to move along the X-axis direction. The movement of the first sliding seat 43 is transmitted to the rotating shaft 45 through the bearing seat 44. Due to the design of the bearing seat 44, the rotating shaft 45 can rotate relative to the first sliding seat 43. When the first sliding seat 43 (and the connected rotating shaft 45 and the transmission gear 48) attempts to move along the X-axis direction, due to the meshing action of the rack and the gear, the transmission gear 48 will roll on the rack. The rolling motion of the transmission gear 48 causes it to rotate, and then the translational motion is converted into rotational motion around its axis through the rotating shaft 45. The rotation of the transmission gear 48 is transmitted to the placement rack 31 through the rotating shaft 45, so that the placement rack 31 rotates 180 degrees around its axis together with the rotating shaft 45. In this way, the placement rack 31 and the workpiece are moved and turned along the X-axis, providing a mobile turning assembly 40 with a compact structure, precise and controllable movement, and high transmission efficiency.

[0059] In a preferred embodiment, the movable flip assembly 40 further includes a limit seat 49, the top surface of the limit seat 49 is provided with a first groove 491, and the bottom surface thereof is provided with a second groove 492 having the same shape and size as the first groove 491;

[0060] The telescopic limit assembly 50 includes an electric telescopic rod 51 and a limit plate 52. The electric telescopic rod 51 is mounted on the support frame, and the limit plate 52 is mounted on the top of the output shaft of the electric telescopic rod 51. The shape and size of the limit plate 52 are consistent with the first groove 491 or the second groove 492.

[0061] When the placement rack 31 is in the first position, when one of the electric telescopic rods 51 remains in the extended state, the electric telescopic rod 51 can drive the limit plate 52 on its top to be engaged in the first groove 491;

[0062] When the placement rack 31 is in the second position and the other electric telescopic rod 51 remains in the extended state, the electric telescopic rod 51 can drive the limiting plate 52 on its top to be engaged in the second groove 492 .

[0063] On the basis of the above structure, when the placement rack 31 needs to be positioned at the first position, the control system sends a signal to one of the electric telescopic rods 51 to keep it in the extended state. After the electric telescopic rod 51 is extended, the limit plate 52 on the top thereof is driven to be engaged in the first groove 491 of the limit seat 49. The tight fit between the limit plate 52 and the first groove 491 enables the placement rack 31 to be firmly positioned at the first position and cannot be further moved or flipped.

[0064] When the placement rack 31 needs to be positioned at the second position, the control system sends a signal to the other electric telescopic rod 51 to keep it in the extended state. After the electric telescopic rod 51 is extended, the limit plate 52 on its top is driven to be engaged in the second groove 492 of the limit seat 49. The tight fit between the limit plate 52 and the second groove 492 enables the placement rack 31 to be firmly positioned at the second position, and it is also impossible to continue to move or flip.

[0065] Thus, the present invention can realize accurate positioning of the placement rack 31 at different positions through the cooperation of the limit seat 49 and the retractable limit assembly 50. This design improves the positioning accuracy and stability of the entire mobile flip assembly 40. The close cooperation between the limit plate 52 and the groove effectively limits the motion range of the placement rack 31, preventing the placement rack 31 from excessive movement or flipping due to accidental or misoperation, thereby enhancing the safety of the system.

[0066] In a preferred embodiment, the fixing fixture 32 includes two electric telescopic cylinders 321, two guide rods 322, and two clamping seats 323; the two guide rods 322 are installed inside the placement rack 31 in parallel along the X-axis direction; the two clamping seats 323 are slidably installed between the two guide rods 322; the clamping seat 323 includes a horizontal support plate 3231, a C-shaped limiting enclosure 3232 and two socket blocks 3233; the limiting enclosure 3232 is installed on the upper surface of the horizontal support plate 3231, one end of the two socket blocks 3233 is respectively connected to the opposite side walls of the limiting enclosure 3232, and the two socket blocks 3233 are respectively socketed with the two guide rods 322; the two electric telescopic cylinders 321 are respectively installed on the left and right side walls of the placement rack 31, and the output shafts of the two electric telescopic cylinders 321 are respectively connected to the two clamping seats 323.

[0067] On the basis of the above structure, firstly, two workpieces are placed on the horizontal support plates 3231 of the two clamping seats 323 respectively. When the workpiece needs to be clamped, the control system sends a signal to the two electric telescopic cylinders 321 to extend them at the same time. The output shaft of the electric telescopic cylinder 321 pushes the clamping seat 323 to move along the guide rod 322 toward the workpiece. The limit enclosure 3232 of the clamping seat 323 gradually approaches the workpiece, and finally clamps the workpiece between the limit enclosure 3232. When the workpiece needs to be released, the control system sends a signal to the two electric telescopic cylinders 321 to retract them at the same time. The output shaft of the electric telescopic cylinder 321 pulls the clamping seat 323 to move along the guide rod 322 away from the workpiece. The limit enclosure 3232 of the clamping seat 323 gradually moves away from the workpiece and finally releases the workpiece. In this way, the present invention can quickly clamp and release the workpiece through the setting of the fixed clamp 32, thereby improving the efficiency of the welding operation. At the same time, through the cooperation of the C-shaped limiting enclosure 3232 and the horizontal support plate 3231, the workpiece can be stably clamped to prevent the workpiece from moving or shaking in the horizontal direction during the welding process.

[0068] In a preferred embodiment, the fixing clamp 32 also includes two pressing assemblies 324, which are symmetrically mounted on the limiting enclosures 3232 of the two clamping seats 323; the pressing assembly 324 includes a rotating seat 3241, an L-shaped frame 3242, a fastening screw 3243, an operating handle 3244 and an abutment seat 3245; the bottom end of the rotating seat 3241 is rotatably connected to the top wall of the corresponding limiting enclosure 3232; the L-shaped frame 3242 is mounted on the rotating seat 3241, and a threaded hole is provided on the top wall of the L-shaped frame 3242; the fastening screw 3243 is threadedly connected to the threaded hole of the L-shaped frame 3242, and an operating handle 3244 is installed on the top of the fastening screw 3243; the abutment seat 3245 is threadedly connected to the bottom end of the fastening screw 3243 through a nut.

[0069] On the basis of the above structure, when it is necessary to clamp the workpiece, the control system sends a signal to the two electric telescopic cylinders 321 to extend them at the same time, drive the clamping seat 323 to move along the guide rod 322 toward the workpiece, and clamp the workpiece between the limiting enclosure 3232. At the same time, the operator manually rotates the operating handle 3244 to drive the fastening screw 3243 to rotate. Since the fastening screw 3243 is threadedly connected to the threaded hole of the L-shaped frame 3242, rotating the fastening screw 3243 will cause the abutment seat 3245 to move downward until the abutment seat 3245 abuts against the top of the workpiece. By adjusting the position of the abutment seat 3245 of the two abutting assemblies 324, it can be ensured that the workpiece is evenly abutted and fixed, and the stability during welding is improved. When it is necessary to release the workpiece, the control system sends a signal to the two electric telescopic cylinders 321 to retract them at the same time, drive the clamping seat 323 to move along the guide rod 322 away from the workpiece, and release the workpiece. At the same time, the operator manually rotates the operating handle 3244 in the opposite direction, driving the fastening screw 3243 to rotate, so that the abutment seat 3245 moves upward and detaches from the workpiece. In this way, the present invention abuts and fixes the top of the workpiece through the abutment assembly 324, further enhancing the stability of the workpiece during the welding process and preventing movement and warping. The design of the rotating seat 3241 allows the L-shaped frame 3242 to rotate within a certain range, so that the abutment assembly 324 can adapt to workpieces of different shapes or positions. The position of the abutment seat 3245 can be adjusted by manually rotating the operating handle 3244, which is simple and quick to operate.

[0070] In a preferred embodiment, the X-axis drive assembly 22 includes two second electric slide rails 221, two second electric sliders 222, and two second sliding seats 223; the two second electric slide rails 221 are symmetrically installed on both sides of the top of the support frame 10; the two second electric sliders 222 are respectively slidably installed on the two second electric slide rails 221; the two second sliding seats 223 are respectively installed on the two second electric sliders 222; the gantry 21 is fixedly connected to the two second sliding seats 223 respectively.

[0071] On the basis of the above structure, when it is necessary to adjust the position of the welding equipment in the X-axis direction, the control system sends a signal to the electric drive device on the second electric slide rail 221. The electric drive device drives the second electric slider 222 to slide along the second electric slide rail 221, and at the same time drives the second sliding seat 223 and the gantry 21 to move together. The welding equipment or other related devices on the gantry 21 move accordingly to reach the desired position. When the welding equipment reaches the desired position, the control system stops sending signals, the electric drive device stops working, and the second electric slider 222, the second sliding seat 223 and the gantry 21 remain stationary. The welding equipment or other related devices remain fixed on the gantry 21 to perform welding operations. The X-axis drive assembly 22 realizes precise adjustment and efficient movement of the position of the welding equipment in the X-axis direction through the mutual cooperation of the second electric slide rail 221, the second electric slider 222, the second sliding seat 223 and the gantry 21. This design not only improves the efficiency and quality of the welding operation, but also ensures the stability of the welding equipment during movement.

[0072] In a preferred embodiment, the welding assembly 23 includes a Y-axis driving assembly 231, a moving seat 232, a lifting driving mechanism 233, a lifting seat 234 and a welding head 235; the Y-axis driving assembly 231 includes a third electric slide rail 2311 and a third electric slider 2312, the third electric slide rail 2311 is installed on the bottom wall of the beam of the gantry 21, and the third electric slider 2312 is slidably matched on the third electric slide rail 2311; the moving seat 232 is fixedly installed on the third electric slider 2312; the lifting driving mechanism 233 includes an electric push rod fixedly installed on the moving seat 232; the lifting seat 234 is installed on the output shaft of the electric push rod; and the welding head 235 is installed on the lifting seat 234. Specifically, in the welding operation, the connection between the welding head 235 and the welding machine is realized by a cable.

[0073] When the position of the welding head 235 in the Y-axis direction needs to be adjusted, the control system sends a signal to the electric drive device on the third electric slide rail 2311. The electric drive device drives the third electric slider 2312 to slide along the third electric slide rail 2311, driving the moving seat 232 and the lifting drive mechanism 233 (including the electric push rod, the lifting seat 234 and the welding head 235) to move together in the Y-axis direction. When the height of the welding head 235 in the Z-axis direction needs to be adjusted, the control system sends a signal to the electric push rod. The electric push rod performs telescopic movement according to the signal, driving the lifting seat 234 and the welding head 235 to move up and down in the Z-axis direction. By adjusting the position and posture of the welding head 235 in the Y-axis and Z-axis directions, it is accurately positioned to the target position in the working area. Then, the control system starts the welding head 235 to perform welding operations. In this way, the present invention realizes the two-dimensional precise movement of the welding head 235 in the Y-axis and Z-axis directions through the cooperation of the Y-axis drive assembly 231 and the lifting drive mechanism 233. This design improves the positioning accuracy and stability of the welding head 235 in the working area, ensuring the welding quality and efficiency. The overall scheme adopts a modular design, and the components are tightly connected and compact in structure. This design not only reduces the occupied space, but also facilitates installation, commissioning and maintenance.

[0074] In a preferred embodiment, a central controller 60 is also provided on the support frame, and a camera device 70 is also installed on the bottom wall of the lifting seat 234. The signal output end of the camera device 70 is connected to the signal input end of the central controller 60, and the signal output end of the central controller 60 is respectively connected to the signal input ends of the X-axis drive component 22, the Y-axis drive component 231, the lifting drive mechanism 233, the fixed clamp 32, the movable flip component 40 and the retractable limit component 50.

[0075] On the basis of the above structure, after the central controller 60 is started, each component is first initialized to ensure that they are in normal working condition. The camera device 70 captures the image information of the welding area in real time and transmits these image signals to the central controller 60. The central controller 60 processes the received image information and identifies the characteristics such as the position, shape and size of the welding area. The central controller 60 plans the moving path and posture adjustment scheme of the welding head 235 according to the processed image information. The central controller 60 sends a control signal to the X-axis drive component 22, the Y-axis drive component 231 and the lifting drive mechanism 233 to drive the welding head 235 to move according to the planned path and posture. After the welding head 235 arrives at the specified position, the central controller 60 starts the welding equipment to perform the welding operation. During the welding process, the camera device 70 continues to capture the image information of the welding area in real time, and the central controller 60 fine-tunes the position and posture of the welding head 235 according to the real-time image information to ensure the welding quality. According to the needs of the welding operation, the central controller 60 can send a control signal to the fixing fixture 32 to fix or release the workpiece. The central controller 60 can also send a control signal to the mobile flip assembly 40 to drive the placement rack 31 to move along the X-axis direction and achieve a 180-degree flip for double-sided welding. The central controller 60 can send a control signal to the retractable limit assembly 50 to limit or release the flipping limit on the placement rack 31. This helps to maintain the stability of the workpiece during the welding process and prevent the workpiece from being displaced or damaged due to flipping. In this way, the present invention achieves a high degree of automation and intelligence through the comprehensive control and management of the central controller 60. This not only improves the efficiency and accuracy of the welding operation, but also greatly reduces the burden on the operator. The introduction of the camera device 70 provides real-time visual feedback for the welding process. The central controller 60 can fine-tune the position and posture of the welding head 235 according to the real-time image information to ensure the welding quality.

[0076] In a preferred embodiment, a dust suction assembly 80 is also provided on the lifting seat 234, and the dust suction assembly 80 is used to absorb welding slag and dust generated in the welding area; the dust suction assembly 80 and the welding head 235 are respectively located on two opposite sides of the lifting seat 234.

[0077] On the basis of the above structure, when the welding head 235 performs welding operation, the dust suction component 80 is started at the same time. The dust suction component 80 sucks the welding slag and dust generated in the welding area through the dust suction pipe 84, and transmits it to the external vacuum cleaner for processing. The suction force of the dust suction component 80 can be adjusted according to the size of the welding area and the amount of welding slag generated to ensure the dust suction effect. The welding head 235 and the dust suction component 80 are respectively located on opposite sides of the lifting seat 234. This layout ensures that the welding operation and the dust suction operation can be carried out at the same time without interfering with each other. The welding head 235 is responsible for performing the welding task, while the dust suction component 80 is responsible for timely removing the welding slag and dust generated during the welding process to keep the welding area clean.

[0078] In a preferred embodiment, the dust suction assembly 80 includes a vertical duct 81, a movable hose 82, a transverse connecting pipe 83 and a plurality of dust suction pipes 84; the vertical duct 81 is fixedly mounted on the side wall of the lifting seat 234 through a connecting block; one end of the movable hose 82 is connected to the upper end of the vertical duct 81, and the other end thereof is connected to an external vacuum cleaner; the transverse connecting pipe 83 is connected to the lower end of the vertical duct 81; the plurality of dust suction pipes 84 are respectively connected to the bottom walls of the transverse connecting pipe 83, the plurality of dust suction pipes 84 are arranged in parallel, and the dust suction ports of the plurality of dust suction pipes 84 are all inclined toward the side of the welding head 235.

[0079] On the basis of the above structure, when the welding head 235 performs welding operation, the dust suction assembly 80 is started at the same time. The dust suction pipe 84 sucks the welding slag and dust generated in the welding area through its inclined dust suction port. The welding slag and dust are collected through the horizontal connecting pipe 83 and enter the vertical duct 81. Then, they are transmitted to the external vacuum cleaner for processing through the movable hose 82. The design of the movable hose 82 allows the dust suction assembly 80 to maintain communication with the external vacuum cleaner when the lifting seat 234 moves up and down, ensuring that the dust suction effect is not affected. The parallel arrangement of the dust suction pipe 84 and the inclined dust suction port design enable the dust suction assembly 80 to adapt to different welding positions and angles, ensuring that the dust suction range is comprehensive and effective.
