Description

Technical Field

[0001] This utility model relates to the field of stamping welding technology, specifically to a stamping welding workbench. Background Technology

[0002] Stamped parts are frequently used in automotive components. When welding stamped parts and other components, they typically need to be placed on a welding worktable. Before welding, the design of the welding worktable is crucial to meet the dual requirements of clamping and positioning accuracy and production efficiency. On one hand, the worktable must have accurate clamping and positioning functions to ensure that the parts remain stable and meet requirements such as perpendicularity during the welding process. On the other hand, to improve production efficiency, welding worktables usually adopt a dual-station design. This design allows welding operations to be performed at one station while parts are assembled or replaced at another station, thus achieving seamless integration and significantly shortening the production cycle.

[0003] For example, patent document with patent application number 202221174669.9 and publication date of August 19, 2022 discloses a dual-station ultrasonic welding workbench for automotive interior parts with high work efficiency, improved welding quality, and reduced defect rate. It includes: a frame, a table plate rotatably mounted on the frame, a drive device mounted on the frame to drive the table plate to rotate relative to the frame, a six-axis robot fixed to one side of the table plate, an ultrasonic welding device mounted on the six-axis robot, and a first positioning device and a second positioning device disposed opposite to each other on the upper part of the table plate; the first and second positioning devices are respectively used to position the first and second workpieces to be ultrasonically welded; the ultrasonic welding device moves under the drive of the six-axis robot and welds the first or second workpiece that has moved to the vicinity of the six-axis robot.

[0004] The above literature considers positioning devices for workpieces to be existing technology. Their specific structure depends on the shape of the workpiece to be positioned, as long as it can reliably position the workpiece on the worktable. However, when machining tubular parts, because the tubular part has an arc-shaped surface and is not a plane, both the circumferential and axial directions of the tubular workpiece need to be precisely controlled, further increasing the difficulty of positioning. For example, when welding tubular workpieces, it is necessary not only to ensure the accurate horizontal position of the tube but also its perpendicularity in the vertical direction, and the arc-shaped surface further complicates the positioning process. Summary of the Invention

[0005] This utility model provides a stamping welding workbench with good clamping effect and high processing efficiency.

[0006] To achieve the above objectives, the technical solution of this utility model is: a stamping welding workbench for assembling and welding parts on a workpiece, comprising a welding workbench, wherein the welding workbench is provided with one or more lifting clamping devices, wherein the lifting clamping device is provided with a lifting fixed seat and a lifting movable seat, wherein the lifting fixed seat and the lifting movable seat clamp the workpiece, wherein one or more positioning clamping devices are provided on one side of the lifting clamping device, wherein the positioning clamping device includes a positioning fixed seat and a positioning movable seat, wherein the positioning movable seat moves closer to or away from the positioning fixed seat to clamp or release the parts, and the positioning fixed seat clamps the parts in a vertical position on the workpiece.

[0007] The above setup uses a lifting fixed seat and a lifting movable seat to clamp the workpiece, ensuring that the workpiece remains horizontal in the horizontal direction. A positioning fixed seat and a positioning movable seat clamp the assembly, ensuring that the assembly is perpendicular to the workpiece in the vertical direction. This prevents the assembly from moving relative to the workpiece during processing, ensuring the processing effect. At the same time, the positioning movable seat can move closer to or further away from the positioning fixed seat to clamp or release the assembly. The clamping operation is simple and the processing efficiency is high.

[0008] Furthermore, one or more positioning clamping devices are provided on one side of the lifting clamping device. The corresponding number of positioning clamping devices can be set according to the needs of the assembly. One or more lifting clamping devices are provided on the welding worktable. When there are two sets of lifting clamping devices, the workpiece and the assembly can be assembled on one lifting clamping device. After assembly, the assembled workpiece and the assembly can be taken to another lifting clamping device for welding. During welding, the next workpiece and assembly can be assembled on the original lifting clamping device, so that welding and assembly of workpieces and assemblies can be carried out simultaneously, thus speeding up production efficiency.

[0009] Furthermore, lifting cylinders are respectively provided on both sides of the lifting moving seat. The lifting cylinders are connected to the lower surface of the welding workbench. The output shaft of the lifting cylinder is connected to the lower surface of the lifting moving seat. A guide sleeve is also provided on one side of the lifting cylinder. A guide rod is slidably mounted on the guide sleeve. The guide rod is connected to the lifting moving seat.

[0010] In the above configuration, the lifting cylinder is located below the welding workbench, but the output shaft of the lifting cylinder can pass through the welding workbench and connect to the lower surface of the lifting moving seat. A guide sleeve is also provided on one side of the lifting cylinder, and a guide rod is slidably mounted on the guide sleeve. The guide rod is connected to the lifting moving seat, that is, the lifting cylinder can drive the lifting moving seat to move. The movement of the lifting moving seat is achieved by driving the guide rod to slide along the guide sleeve, which ensures the verticality of the movement of the lifting moving seat.

[0011] Furthermore, the bottom of the lifting and fixing seat is fixedly connected to the welding worktable.

[0012] The above configuration, with its firm connection between the lifting and fixing base and the welding worktable, ensures high stability of the lifting and fixing base during processing, effectively preventing the workpiece from loosening or falling off during welding.

[0013] Furthermore, the workpiece is provided with positioning holes on both sides, the lifting fixing seat is provided with a lifting fixing block, the lifting fixing block is provided with a lifting fixing hole, the lifting moving seat is provided with a lifting moving block, the lifting moving block is provided with a lifting protrusion, the lifting protrusion is matched with the positioning hole, and the lifting protrusion is matched with the lifting fixing hole.

[0014] Before assembly or welding, the above setup involves the lifting cylinder moving the lifting moving seat downwards to place the positioning hole on the workpiece onto the lifting protrusion. Then, the lifting cylinder moves the lifting moving seat upwards, causing the lifting protrusion to extend into the lifting fixing hole, thus completing the positioning of the workpiece. Because the lifting protrusion, positioning hole, and lifting fixing buckle are matched, the workpiece can be kept level.

[0015] Furthermore, the bottom of the positioning and fixing seat is connected to the welding worktable, one side of the positioning and fixing seat is connected to the positioning cylinder, one side of the positioning cylinder is provided with a positioning hinge seat, the positioning hinge seat and the positioning moving seat are hinged together, and the output shaft of the positioning cylinder is hinged to the positioning moving seat.

[0016] In the above configuration, the bottom of the positioning and fixing seat is connected to the welding worktable, and one side of the positioning and fixing seat is connected to the positioning cylinder, which can ensure the stability of the positioning cylinder during operation. The positioning hinge seat and the positioning moving seat are hinged together, and the output shaft of the positioning cylinder is hinged to the positioning moving seat. When the output shaft of the positioning cylinder extends, it can make the positioning moving seat approach the positioning and fixing seat to complete the clamping and positioning of the assembly. When the output shaft of the positioning cylinder retracts, it can make the positioning moving seat move away from the positioning and fixing seat to release the clamping and positioning of the assembly.

[0017] Furthermore, the assembly is provided with an assembly part, the positioning moving seat is provided with a positioning moving groove, and the positioning fixed seat is provided with a positioning protrusion, the positioning protrusion being matched with the positioning moving groove.

[0018] With the above configuration, when the output shaft of the positioning cylinder extends, the positioning moving seat can approach the positioning fixed seat. At this time, the positioning fixed seat is provided with a positioning protrusion, which can pass through the assembly part and abut against the positioning moving groove on the positioning moving seat.

[0019] Furthermore, the assembly is also provided with an abutment part, and the positioning moving seat is provided with a positioning moving block, which is matched and configured to match the abutment part.

[0020] With the above configuration, when the output shaft of the positioning cylinder extends, the abutting part can abut against the positioning moving seat when it approaches the positioning fixed seat, thereby positioning the assembly between the positioning fixed seat and the positioning moving seat.

[0021] Furthermore, the welding workbench includes a side connecting plate, an upper connecting plate, and a workstation. The side connecting plate is provided with a side connecting hole, the upper connecting plate is connected to the side connecting hole, and the upper connecting plate is connected to the workstation.

[0022] With the above settings, when you want to adjust the height of the workstation, you can connect the upper connecting plate to the side connecting holes at different positions, so that the workstation can be at different heights.

[0023] Furthermore, a pull ring is provided on the workstation.

[0024] With the above settings, when you want to adjust the height of the workstation, you can pull the workstation with the pull ring so that the weight of the workstation is no longer acting on the upper connecting plate. Then, disconnect the connection between the upper connecting plate and the side connecting plate, adjust the position of the workstation, and then connect the upper connecting plate and the side connecting plate to complete the height adjustment of the workstation.

[0025] Furthermore, there are two or more sets of lifting and clamping devices, and baffles are provided between adjacent lifting and clamping devices.

[0026] The above setup allows the welding workbench to be divided into two stations by a baffle, and prevents interference between the two stations. Attached Figure Description

Detailed Implementation

[0040] Example 1.

[0041] like Figure 1-12 As shown, a stamping welding workbench is used to weld assemblies 5 on a workpiece 4. The workbench 1 includes a welding workbench 1 equipped with one or more lifting and clamping devices 2. Each lifting and clamping device 2 includes a lifting fixed seat 23 and a lifting movable seat 22, which clamp the workpiece 4. One or more positioning clamping devices 3 are provided on one side of the lifting and clamping device 2. Figure 7 As shown, the positioning and clamping device 3 includes a positioning fixed seat 33 and a positioning movable seat 32, which clamp the assembly 5.

[0042] like Figure 1-4As shown in Figures 10 and 11, lifting cylinders 21 are respectively provided on both sides of the lifting moving base 22. The lifting cylinders 21 are connected to the lower surface of the welding worktable 1, and the output shaft 211 of the lifting cylinder is connected to the lower surface of the lifting moving base 22. A guide sleeve 25 is also provided on one side of the lifting cylinder 21. A guide rod 24 is slidably sleeved on the guide sleeve 25. The guide rod 24 is connected to the lifting moving base 22. The lifting moving base 22 is provided with one or more limiting grooves 220. The limiting grooves 220 are matched with the outer side wall of the workpiece 4, so that the middle part of the workpiece 4 is placed in the limiting grooves 220. The lifting cylinder 21 is located below the welding workbench 1, but the output shaft 211 of the lifting cylinder can pass through the welding workbench 1 and connect to the lower surface of the lifting moving seat 22. A guide sleeve 25 is also provided on one side of the lifting cylinder 21. A guide rod 24 is slidably sleeved on the guide sleeve 25. The guide rod 24 is connected to the lifting moving seat 22. That is, the lifting cylinder 21 can drive the lifting moving seat 22 to move. The movement of the lifting moving seat 22 is achieved by driving the guide rod 24 to slide along the guide sleeve 25, which ensures the verticality of the movement of the lifting moving seat 22.

[0043] The bottom of the lifting and fixing seat 23 is connected to the welding worktable 1. The firm connection between the lifting and fixing seat 23 and the welding worktable 1 makes the lifting and fixing seat 23 highly stable during the processing, which can effectively prevent the workpiece 4 from loosening or falling off during the welding process.

[0044] like Figure 10 As shown, positioning holes 41 are provided on both sides of the workpiece 4. The lifting fixing seat 23 is provided with a lifting fixing block 231, and the lifting fixing block 231 is provided with a lifting fixing hole 2311. The lifting moving seat 22 is provided with a lifting moving block 221, and the lifting moving block 221 is provided with a lifting protrusion 2211. The lifting protrusion 2211 is matched with the positioning hole 41, and the lifting protrusion 2211 is matched with the lifting fixing hole 2311. Before assembly or welding, the lifting cylinder 21 drives the lifting moving seat 22 to move downward, placing the positioning hole 41 on the workpiece 4 on the lifting protrusion 2211. Then, the lifting cylinder 21 drives the lifting moving seat 22 to move upward, so that the lifting protrusion 2211 extends into the lifting fixing hole 2311, completing the positioning of the workpiece 4. Since the lifting protrusion 2211, the positioning hole 41 and the lifting fixing buckle are matched, the workpiece 4 can be kept horizontal.

[0045] like Figure 5-10As shown, the bottom of the positioning and fixing seat 33 is fixedly connected to the welding worktable 1. One side of the positioning and fixing seat 33 is connected to the positioning cylinder 31. A positioning hinge seat 312 is provided on one side of the positioning cylinder 31. The positioning hinge seat 312 and the positioning moving seat 32 are hinged together. The output shaft 311 of the positioning cylinder is hinged to the positioning moving seat 32. The bottom of the positioning and fixing seat 33 is connected to the welding worktable 1, and one side of the positioning and fixing seat 33 is connected to the positioning cylinder 31. This connection ensures the stability of the positioning cylinder 31 during operation. Furthermore, the positioning hinge seat 312 and the positioning moving seat 32 are hinged together, and the output shaft 311 of the positioning cylinder is hinged to the positioning moving seat 32. When the output shaft 311 of the positioning cylinder extends, it allows the positioning moving seat to move. The movable seat 32 approaches the positioning fixed seat 33 to complete the clamping and positioning of the assembly 5. When the positioning cylinder output shaft 311 retracts, the positioning hinge seat 312 will not move because it is located at one end of the positioning cylinder 31. Therefore, when the positioning cylinder output shaft 311 retracts, it drives the positioning movable seat 32 connected to the positioning cylinder output shaft 311 to move back. The part connected to the positioning hinge seat 312 and the positioning movable seat 32 will not move. This allows the positioning movable seat 32 to rotate around the connection between the positioning movable seat 32, the positioning hinge seat 312, and the positioning cylinder output shaft 311, thereby moving the positioning movable seat 32 away from the positioning fixed seat 33 and releasing the clamping and positioning of the assembly 5.

[0046] like Figure 10 As shown, the assembly 5 is provided with an assembly part 51, the positioning moving seat 32 is provided with a positioning moving groove 321, and the positioning fixed seat 33 is provided with a positioning protrusion 331. The positioning protrusion 331 is matched with the positioning moving groove 321. When the output shaft 311 of the positioning cylinder extends, the positioning moving seat 32 can be brought close to the positioning fixed seat 33. At this time, the positioning fixed seat 33 is provided with a positioning protrusion 331, which can pass through the assembly part 51 and abut against the positioning moving groove 321 on the positioning moving seat 32.

[0047] The assembly 5 is also provided with an abutment part 52, and a positioning moving seat 32 is provided with a positioning moving block 322. The positioning moving block 322 is matched with the abutment part 52. When the output shaft 311 of the positioning cylinder extends, the positioning moving seat 32 can approach the positioning fixed seat 33, and the abutment part 52 can abut against the positioning moving block 322, thereby making the assembly 5 located between the positioning fixed seat 33 and the positioning moving seat 32.

[0048] like Figure 1 and 12As shown, the welding workbench 1 includes a side connecting plate 11, an upper connecting plate 12, and a work platform 13. The side connecting plate 11 is provided with a side connecting hole 111. The upper connecting plate 12 is connected to the side connecting hole 111 and the work platform 13. When it is desired to adjust the height of the work platform 13, the upper connecting plate 12 can be connected to the side connecting holes 111 at different positions to allow the work platform 13 to be at different heights.

[0049] The workstation 13 is equipped with a pull ring 6. When you want to adjust the height of the workstation 13, you can pull the workstation 13 through the pull ring 6 so that the weight of the workstation no longer acts on the upper connecting plate 12. Then, disconnect the connection between the upper connecting plate 12 and the side connecting plate 11, adjust the position of the workstation 13, and then connect the upper connecting plate 12 and the side connecting plate 11 to complete the height adjustment of the workstation 13.

[0050] A baffle 7 is provided between the two lifting and clamping devices 2, which can divide the welding workbench 1 into two workstations and prevent the two workstations from interfering with each other.

[0051] The working principle of this utility model is as follows: the lifting fixed seat 23 and the lifting moving seat 22 clamp the workpiece 4 to ensure that the workpiece 4 remains horizontal in the horizontal direction, and the positioning fixed seat 33 and the positioning moving seat 32 clamp the assembly 5 to ensure the perpendicularity of the assembly 5 in the vertical direction of the workpiece 4.

[0052] Furthermore, one or more positioning clamping devices 3 are provided on one side of the lifting clamping device 2. The corresponding number of positioning clamping devices 3 can be set according to the needs of the assembly 5. One or more lifting clamping devices 2 are provided on the welding workbench 1. When there are two sets of lifting clamping devices 2, the workpiece 4 and the assembly 5 can be assembled on one lifting clamping device 2. After assembly, the workpiece 4 and the assembly 5 can be taken to another lifting clamping device 2 for welding. During welding, the next workpiece 4 and the assembly 5 can be assembled on the original lifting clamping device 2, so that welding and assembly of workpiece 4 and the assembly 5 can be carried out simultaneously, thus speeding up production efficiency.

[0053] Before assembly or welding, the lifting cylinder 21 drives the lifting moving seat 22 to move downward, placing the positioning hole 41 on the workpiece 4 onto the lifting protrusion 2211. Then, the lifting cylinder 21 drives the lifting moving seat 22 to move upward, so that the lifting protrusion 2211 extends into the lifting fixing hole 2311, completing the positioning of the workpiece 4. Since the lifting protrusion 2211, the positioning hole 41 and the lifting fixing buckle are matched, the workpiece 4 can be kept horizontal.

[0054] When the output shaft 311 of the positioning cylinder extends, the positioning moving seat 32 can approach the positioning fixed seat 33. At this time, the positioning fixed seat 33 is provided with a positioning protrusion 331. The positioning protrusion 331 can pass through the assembly part 51 and abut against the positioning moving groove 321 on the positioning moving seat 32. When the output shaft 311 of the positioning cylinder extends, the positioning moving seat 32 can approach the positioning fixed seat 33, and the abutting part 52 can abut against the positioning moving block 322, thereby making the assembly part 5 located between the positioning fixed seat 33 and the positioning moving seat 32.
