Positioning fixtures for plate welding Technical Field
[0001] This utility model relates to the field of positioning tooling technology, and in particular to a positioning tooling for welding sheet metal. Background Technology
[0002] Automatic welding machines are used for processing precision hardware, electrical appliances, auto parts, instruments, sanitary ware, watches, electronic parts, and hardware furniture. Commonly used welding processes on automatic welding machines include MIG welding, TIG welding, pulse welding, submerged arc welding, laser welding, and laser hybrid welding. During welding, positioning fixtures are required to fix the workpiece.
[0003] When positioning plates for welding, the plates to be welded are usually first placed on a positioning block for initial positioning. The clamping device then presses down to fix the plates stably on the positioning block. However, during the welding process after positioning, the heat generated may not be effectively dissipated by the material of the positioning block itself, which may cause thermal deformation of the tooling. Especially for high-precision plate welding, thermal deformation of the tooling may cause the positioning position of the plate to change, affecting the welding accuracy. Therefore, this application proposes a positioning tooling for plate welding. Summary of the Invention
[0004] The purpose of this invention is to address the problem in the prior art that during the welding process, the heat generated may not be effectively dissipated by the material of the positioning block itself, which may cause thermal deformation of the tooling, resulting in changes in the positioning position of the plate and affecting the welding accuracy. The invention proposes a positioning tooling for plate welding.
[0005] The technical solution of this utility model: a positioning fixture for welding plates, including a substrate, and further comprising:
[0006] A positioning block is fixedly installed on the base plate. A fixing frame is fixedly provided on one side of the positioning block on the base plate. A cylinder is fixedly installed at the bottom end of the fixing frame. A connecting plate is fixedly connected to the piston rod of the cylinder. A clamping plate is fixedly installed on one side of the connecting plate. A guide groove is provided on the top side of the base plate away from the fixing frame. A moving block is slidably installed in the guide groove.
[0007] A dispersion device, which is disposed on a substrate for dispersing and conducting heat on a positioning block;
[0008] A suction mechanism, which is mounted on a moving block, is used for the automatic collection of spatter and dust generated during the welding process.
[0009] Optionally, the dispersion device includes a support frame fixedly mounted on the substrate, a water storage tank on the top of the support frame, a heat-conducting plate fixedly mounted on the bottom wall of the water storage tank, a heat dissipation plate fixedly connected to the heat-conducting plate, a heat-conducting pipe fixedly connected to the heat-conducting plate on one side of the positioning block, and an acceleration device inside the water storage tank.
[0010] Optionally, the acceleration device includes a connecting groove fixedly installed on one side of the water storage tank. The connecting groove is provided with a sliding groove, and a slider is slidably installed in the sliding groove. A positioning rod is fixedly installed on the slider, and a positioning frame is fixedly connected to the bottom end of the positioning rod. A rotating roller is rotatably installed on the positioning frame, and multiple sets of soft bristles are provided on the curved surface of the rotating roller.
[0011] Optionally, a lead screw threadedly connected to the slider is rotatably installed inside the slide groove, and a drive motor is fixedly installed on the outside of the connecting groove, with the output shaft of the drive motor and the lead screw fixedly connected.

[0015] In summary, this application includes at least one of the following beneficial technical effects:
[0016] 1. By setting up heat pipes, heat dissipation plates, heat storage tanks, sliders, rotating rollers, and soft bristles, the heat generated during the welding process of the positioning blocks can be dispersed to the heat dissipation plates for heat dissipation through the heat transfer of heat pipes and heat dissipation plates. In conjunction with the sliding of the slider and the rotation of the rotating rollers, the flexible deformation of the soft bristles can generate multi-scale eddies, break the laminar boundary layer of the cooling water, and increase the turbulence intensity, thereby enhancing the heat conduction efficiency, significantly improving the cooling and heat dissipation effect, avoiding the possibility that the thermal deformation of the tooling may cause changes in the positioning position of the plate, and improving the welding accuracy.
[0017] 2. By setting up gears, racks, guide grooves, moving blocks, exhaust fans, collection boxes, and exhaust pipes, the meshing of gears and racks causes the slider to slide while driving the moving blocks to move. Combined with the suction effect of the exhaust pipes, the spatter and dust generated during the welding process are sucked into the collection box for collection, avoiding the difficulty of cleaning gaps and corners in the subsequent working area and extending the service life of the device.
[0018] This invention enables the rapid dispersion and transfer of heat generated during the welding process of the positioning block, and allows the flexible deformation of the soft bristles to generate multi-scale eddies, breaking the laminar boundary layer of the cooling water, increasing the intensity of turbulence, thereby enhancing the heat transfer efficiency, significantly improving the cooling and heat dissipation effect, and extending the service life of the device.

[0030] Example
[0031] As shown in Figures 1 and 2, the positioning fixture for plate welding proposed in this utility model includes a base plate 1 and a positioning block 2 fixedly installed on the base plate 1. A fixing frame 3 is fixedly installed on one side of the positioning block 2 on the base plate 1. A cylinder 4 is fixedly installed at the bottom end of the fixing frame 3. A connecting plate 5 is fixedly connected to the piston rod of the cylinder 4. A clamping plate 6 is fixedly installed on one side of the connecting plate 5. The plate to be welded is first placed on the positioning block 2 for initial positioning. The piston rod of the cylinder 4 extends and drives the connecting plate 5 to move downward, so that the clamping plate 6 clamps and fixes the plate to be welded, avoiding shaking during the subsequent welding process from affecting the welding quality.
[0032] In addition, a guide groove 14 is provided on the side of the top of the substrate 1 away from the fixing frame 3. A moving block 19 is slidably installed in the guide groove 14. The guide groove 14 is fixedly installed on the surface of the substrate 1 by bolts, which facilitates disassembly and maintenance in the future.
[0033] As shown in Figures 1-3, the device also includes a dispersion device, which is set on the substrate 1 for dispersing and conducting heat on the positioning block 2. The dispersion device includes a support frame 7 fixedly installed on the substrate 1. A water storage tank 8 is provided on the top of the support frame 7. A heat-conducting plate 22 is fixedly installed on the bottom wall of the water storage tank 8. A heat dissipation plate 23 is fixedly connected to the heat-conducting plate 22. A heat-conducting pipe 10 fixedly connected to the heat-conducting plate 22 is installed on one side of the positioning block 2. A water inlet pipe and a water outlet pipe are installed on both sides of the water storage tank 8, and valves are provided on both the water inlet pipe and the water outlet pipe. Water is poured into the water storage tank 8 to a certain height through the water inlet pipe, so that the heat generated by welding is transferred to the heat-conducting plate 22 through the heat-conducting pipe 10. Finally, the heat dissipation plate 23 located in the cooling water dissipates heat, thereby dispersing and conducting heat and improving the cooling effect.
[0034] Furthermore, an acceleration device is installed inside the water storage tank 8. The acceleration device includes a connecting groove 9 fixedly installed on one side of the water storage tank 8. A sliding groove is provided in the connecting groove 9, and a slider 24 is slidably installed in the sliding groove. A positioning rod 26 is fixedly installed on the slider 24. A positioning frame 27 is fixedly connected to the bottom end of the positioning rod 26. A rotating roller 28 is rotatably installed on the positioning frame 27. Multiple sets of soft bristles 29 are provided on the curved surface of the rotating roller 28. A motor for driving the rotating roller 28 to rotate is installed on one side of the positioning frame 27, and a waterproof motor cover is installed outside the motor. The rotation of the rotating roller 28 causes the soft bristles 29 to deform flexibly and generate multi-scale eddies, breaking the laminar boundary layer of the cooling water, increasing the turbulence intensity, thereby enhancing the heat transfer efficiency, significantly improving the cooling and heat dissipation effect, avoiding the possibility that the thermal deformation of the tooling may cause changes in the positioning position of the plate, and improving the welding accuracy.
[0035] Furthermore, an inclined baffle 25 is fixedly installed on the inner bottom wall of the connecting groove 9. The inclined baffle 25 is located above the positioning rod 26. The water level in the water tank 8 is lower than that in the connecting groove 9 and is covered by the heat dissipation plate 23. The inclined baffle 25 can prevent cooling water from entering the trough during the stirring process. A lead screw 18, which is threadedly connected to the slider 24, is rotatably installed in the trough. A drive motor 17 is fixedly installed on the outer side of the connecting groove 9. The output shaft of the drive motor 17 is fixedly connected to the lead screw 18. When the drive motor 17 is started, the lead screw 18 rotates. The slider 24 drives the positioning rod 26 to move along the direction of the trough, expanding the rotation area of the rotating roller 28 and making the cooling effect better.
[0036] As shown in Figure 2-4, the device also includes a suction mechanism, which is set on the movable block 19 for the automatic collection of spatter and dust generated during the welding process. The suction mechanism includes a mounting plate 15 fixedly installed on the movable block 19, a collection box 16 fixedly installed on the mounting plate 15, an exhaust fan 20 on one side of the collection box 16, an exhaust pipe 21 fixedly installed on the exhaust fan 20, and multiple suction nozzles on the exhaust pipe 21. By using the exhaust fan 20 in conjunction with the exhaust pipe 21, spatter and dust generated during the welding process can be sucked up, which is beneficial to protecting the working environment.
[0037] It is worth noting that one end of the lead screw 18 passes through the outer wall of the connecting groove 9 and is fixedly connected to a gear 11. A rack 12 meshes with the gear 11. A support rod 13, which is fixedly connected to the moving block 19, is fixedly installed at the bottom of the rack 12. The rotation of the lead screw 18 causes the gear 11 to rotate, and the meshing rack 12 drives the moving block 19 to move, further expanding the suction range of the exhaust pipe 21 and improving the suction effect.
[0038] Working principle: Starting the drive motor 17 causes the lead screw 18 to rotate. At this time, the slider 24 drives the positioning rod 26 to move along the direction of the groove. In conjunction with the rotation of the rotating roller 28, the soft bristles 29 are agitated, expanding the agitation range of the soft bristles 29. The flexible deformation of the soft bristles 29 can generate multi-scale eddies, breaking the laminar boundary layer of the cooling water, increasing the turbulence intensity, thereby enhancing the heat transfer efficiency, significantly improving the cooling and heat dissipation effect, avoiding the possibility of changes in the positioning position of the plate due to the thermal deformation of the tooling, and improving the welding accuracy. At the same time as the lead screw 18 rotates, the gear 11 rotates, and the rack 12 drives the moving block 19 to move, expanding the suction range of the exhaust pipe 21. This allows the exhaust pipe 21 to suck up the spatter and dust generated during the welding process, which helps protect the working environment and extends the service life of the device.
[0039] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
