Description

Technical Field

[0002] Automated spot welding machines, a type of resistance welding equipment, weld metal parts by applying pressure through electrodes and utilizing the heat generated by contact resistance. Structurally, they have automated drive and control components, enabling precise welding of electrical components (such as terminals and conductive connectors). In the field of power equipment manufacturing, they are used to achieve efficient and stable metal connections, ensuring the conductivity and structural strength of electrical components.

[0003] In the welding of metal workpieces such as electrical components and hardware parts, the welding table, as the core equipment that supports the workpiece and works in conjunction with the welding machine to complete the welding operation, directly affects welding efficiency, welding accuracy, and operational safety through its structural design and functional performance. With the increasing automation of the manufacturing industry, traditional welding tables have gradually revealed many problems that make them unable to meet the demands of modern production. For example, traditional welding tables are mostly fixed structures, requiring operators to frequently assist in supporting the workpiece and cooperating with the welding machine for welding. This not only increases labor intensity but also easily leads to misalignment of the welding reference due to placement deviations, affecting welding quality and failing to meet the demands of modern manufacturing for efficient, high-precision, and automated welding operations. Therefore, developing a welding table that reduces the degree of manual assistance in welding and improves the quality and efficiency of batch metal workpiece welding is a technical problem that urgently needs to be solved in this case.

[0020] The following is for reference. Figure 1-5 Description of embodiments of the present utility model An automatic feeding and flipping welding table includes: The frame 100 is movable and installed on the side of the welding machine A00; The flip plate 200 reciprocates on the frame 100 via a drive mechanism; The hollow rotating platform 300 is fixedly mounted on the tilting plate 200 and is driven by a motor to rotate the load flange. The turntable 400 is fixedly connected to the rotating flange of the hollow rotating platform 300 on its back side, and has a workpiece welding position on its front side.

[0021] In this case, the welding position of the workpiece is a welding receiving groove that is adapted to the workpiece.

[0022] The workpiece is provided with a positioning mechanism 500 on the side of the welding position that is adapted to the workpiece; Positioning mechanism 500 includes: A positioning linear drive mechanism 510 is fixedly installed on the front side of the turntable 400; The positioning pad 520 has an L-shaped structure and is fixedly connected to the telescopic rod end of the positioning linear drive mechanism 510; A positioning nylon pressure plate 530 is fixedly mounted on the positioning pad 520. When the telescopic rod of the positioning linear drive mechanism 510 extends, the positioning nylon pressure plate 530 secures the workpiece to the workpiece welding position. The front end of the positioning nylon pressure plate 530 in this design has a chamfer to facilitate pressing the workpiece in.

[0023] The positioning linear drive mechanism 510 includes a positioning cylinder, a positioning hydraulic cylinder, or a positioning electric push rod.

[0024] In the positioning mechanism 500 of this case, a hinge spring 540 can be added, such as... Figure 5As shown, one side of the hinge spring 540 is fixedly connected to the piston rod end of the positioning linear drive mechanism 510, and the other side is fixedly connected to the positioning pad 520; the positioning nylon pressure plate 530 is fixed to the positioning pad 520. The elastic positioning pad 520 prevents the welded parts from becoming one with the welding machine during the welding process, causing the lower nozzle A30 to rise and the welded parts to stick to it, thus preventing the positioning linear drive mechanism 510 from being damaged.

[0025] The bottom of the flip plate 200 is provided with a fixedly connected rotating shaft 210; the rotating shaft 210 is rotatably mounted on the frame 100 through a pair of bearing seats.

[0026] In this invention, a transition plate is provided between the bottom of the flip plate 200 and the shaft 210; the shaft 210 is provided with a connecting groove that is adapted to the transition plate, and the bottom of the connecting groove is a plane, which improves the accuracy of the connection between the shaft 210 and the flip plate 200.

[0027] The flip plate 200 is driven to reciprocate and flip via the flip drive mechanism 220; One end of the flipping drive mechanism 220 is hinged to the frame 100, and the other end is hinged to the bottom of the flipping plate 200.

[0028] The tilting drive mechanism 220 includes a tilting cylinder, a tilting hydraulic cylinder, or a tilting electric push rod.

[0029] The frame 100 is horizontally slidably mounted on the base 600 via a pair of feeding guide rails. An alignment slide 700 is provided between the base 600 and the frame 100. A pair of the feeding guide rails are fixedly mounted on the top surface of the alignment slide 700; A pair of alignment guide rails perpendicular to the feeding guide rails are fixedly provided on the top surface of the base 600; the alignment slide 700 is slidably disposed on the pair of alignment guide rails.

[0030] In this case, the frame 100 reciprocates horizontally on the alignment slide 700 via a linear feeding drive mechanism 800. One end of the linear feeding drive mechanism 800 is fixedly connected to the alignment slide 700, and the other end is hinged to the frame 100. The aforementioned linear feeding drive mechanism includes a feeding cylinder, a feeding hydraulic cylinder, or a feeding electric push rod.

[0031] A slide positioning mechanism 900 is provided on the base 600. The cylinder of the slide positioning mechanism is hinged to the base 600, and the piston rod end is fixedly connected to the alignment slide 700. By extending and retracting the piston rod of the slide positioning mechanism 900, the correspondence between the workpiece and the welding machine 200 is adjusted. After adjustment, the slide positioning mechanism 900 is locked. In this case, the slide positioning mechanism 900 includes a slide positioning cylinder, a slide positioning hydraulic cylinder, or a slide positioning electric push rod.

[0032] The workflow for the flip welding station in this case includes: Step 1, with Figure 1 For example, by using the extension and retraction of the piston rod of the slide positioning mechanism 900, the longitudinal direction (width direction of the base 600) of the alignment slide 700 is adjusted so that the first workpiece B10 to be welded corresponds to the electrode of the welding machine A00. Step 2: With the turntable 400 in a horizontal position, place the first workpiece B10 to be welded at the workpiece welding position, and fix the first workpiece B10 to be welded on the turntable 400 through the positioning mechanism. Step 3: The piston rod of the flipping drive mechanism 220 retracts, and the turntable 400 rotates towards the welding machine A00, becoming vertical and perpendicular to the horizontal plane. Step four: The frame 100 slides towards the welding machine A00 via the feeding linear drive mechanism 800. After the first workpiece B10 to be welded reaches the set position, the electrode A10 moves upward to the predetermined welding point via the bottom lifting platform A20 (the top of the electrode A10 is conical, and in this case, the first workpiece B10 to be welded is a U-shaped support strip with through holes at both ends. The electrode A10 extends into the through holes, and the top protrudes from the through holes). The robot arm places the second workpiece B20 to be welded onto the motor A10, which protrudes from the top through hole of the first workpiece B10. The lower nozzle A30 of the welding machine presses down to weld the first workpiece B10 and the second workpiece B20. The top of the electrode A10 is provided with a positioning pin made of insulating material (the outer metal layer is provided with an insulating layer or ceramic) to facilitate the positioning of the workpiece and the nut.

[0033] Step 5: After welding in Step 4 is completed, electrode A10 descends, lower nozzle A30 rises, and turntable 400 rotates 180° to weld the other end of the first workpiece B10 to be welded. The welding process is the same as in Step 4.

[0034] Step six: After welding is completed at both ends of the first workpiece B10, electrode A10 descends, lower nozzle A30 rises, and frame 100 retracts. Figure 1 At the right end, the turntable 400 flips to a horizontal position, the positioning mechanism disengages from the first workpiece B10 to be welded, and the first workpiece B10 to be welded can be removed.
