[0002] The cathode plate used in metal electrolysis is mainly composed of two parts: the cathode base plate and the cathode conductive beam. Both the cathode base plate and the conductive beam are made of aluminum and need to be welded together using gas shielded welding.

[0003] Traditional welding devices, such as the one described in announcement number CN211915975U as an automatic cathode plate flipping welding device, include a base with platform support frames at both ends, a welding platform rotatably mounted between the two platform support frames, and the frame rotation shafts at both ends of the welding platform connected to the upper end of the platform support frame through bearing seats; a welding gun is mounted above the welding platform at the position where the cathode base plate and the cathode conductive beam meet, the welding gun is connected to the telescopic end of the welding gun lifting cylinder, the fixed end of the welding gun lifting cylinder is connected to the sliding welding frame, and the sliding welding frame is mounted on a sliding track on the upper side of the guide beam.

[0004] The aforementioned device can only clamp and fix workpieces of a single size during use, resulting in low flexibility. Therefore, we propose an automatic flipping welding platform to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an automatic flipping welding platform to solve the problem mentioned in the background art that the existing devices can only clamp and fix workpieces of a single size during use, resulting in low flexibility.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic flipping welding platform, including a fixed base, with support frames installed above the front and rear ends of the fixed base. A bearing seat is installed above the front support frame, and a connecting base is installed above the rear support frame. A welding clamping frame is rotatably connected between the connecting base and the bearing seat. Bidirectional lead screw guides are installed on both sides of the inner wall of the welding clamping frame. A belt drive cover is installed at the rear end of the connecting base, and a drive motor is installed on the outer wall of the belt drive cover.

[0007] Preferably, the belt drive cover is provided with a belt drive mechanism inside, and the output end of the drive motor passes through and extends into the inside of the belt drive cover, and is connected to the welding clamping frame through the belt drive mechanism.

[0008] Preferably, the bidirectional lead screw guide rail includes a guide rail base, inside which a forward lead screw and a reverse lead screw are installed. The forward lead screw and the reverse lead screw are connected end to end, and a bearing plate is installed at the connection. Both the forward lead screw and the reverse lead screw are drivenly connected to a slider, and a clamping mechanism is installed on the slider.

[0009] Preferably, a synchronous seat is installed at one end of each of the two-way lead screw guide rails on both sides. The synchronous seats are connected by a synchronous shaft. A servo motor is installed at one end of the synchronous shaft. One end of the reverse lead screw passes through and extends into the interior of the synchronous seat and is equipped with a worm gear. The outer walls of both ends of the synchronous shaft are provided with worm threads, and the synchronous shaft is connected to the worm gear through the worm threads.

[0010] Preferably, the clamping mechanism includes a cylinder and a V-shaped chuck, the V-shaped chuck being mounted on the output end of the cylinder.

[0011] Preferably, a rubber pad is provided on the end face of the V-shaped clamp, and the rubber pad is bonded to the V-shaped clamp.

[0012] Preferably, the fixing base is equipped with a reinforcing rod inside, and multiple reinforcing rods are provided, with both ends of the reinforcing rods being welded to the fixing base.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can adjust the distance between the two side clamping mechanisms according to the length of the workpiece. During adjustment, the servo motor is driven to run, which drives the synchronous shaft to rotate. The worm gears at the ends of the bidirectional lead screw guide rails on both sides mesh with the worm threads on the outer walls of the synchronous shaft to drive the forward lead screw and the reverse lead screw to rotate. This causes the sliders on the forward lead screw and the reverse lead screw to move in opposite directions, so as to achieve the effect of synchronously adjusting the distance between the clamping mechanisms of the bidirectional lead screw guide rails on both sides. This improves the clamping flexibility and solves the problem that the existing device can only clamp and fix workpieces of a single size during use, resulting in low flexibility.

[0015] (2) This utility model uses side clamping to fix the workpiece. After fixing, the upper and lower surfaces of the workpiece are in an unobstructed state. After the single-sided welding of the workpiece is completed, the drive motor can be driven to run. Under the action of the belt transmission mechanism, the welding clamping frame is automatically flipped, which facilitates double-sided processing of the workpiece and improves processing flexibility.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4 This utility model provides an embodiment of an automatic flipping welding platform, comprising a fixed base 1, with support frames 2 mounted on the top of both the front and rear ends of the fixed base 1. A bearing seat 3 is mounted on the top of the front support frame 2, and a connecting base 4 is mounted on the top of the rear support frame 2. A welding clamping frame 5 is rotatably connected between the connecting base 4 and the bearing seat 3. Bidirectional screw guide rails 6 are mounted on both sides of the inner wall of the welding clamping frame 5. A belt drive cover 11 is mounted on the rear end of the connecting base 4. A drive motor 12 is mounted on the outer wall of the belt drive cover 11. A belt drive mechanism is provided inside the belt drive cover 11. The output end of the drive motor 12 penetrates and extends into the interior of the belt drive cover 11, and is connected to the welding clamping frame 5 via the belt drive mechanism. The bidirectional screw guide rail 6 includes a guide rail seat 601. The internal components of component 1 are equipped with a forward lead screw 602 and a reverse lead screw 603, which are connected end to end and a bearing plate 604 is installed at the connection. Both the forward lead screw 602 and the reverse lead screw 603 are connected to a slider, and a clamping mechanism 7 is installed on the slider. One end of each of the two-way lead screw guide rails 6 is equipped with a synchronous seat 8, which is connected to each other by a synchronous shaft 9. One end of the synchronous shaft 9 is equipped with a servo motor 10. One end of the reverse lead screw 603 passes through and extends into the interior of the synchronous seat 8, and a worm gear 13 is installed thereon. The outer walls of both ends of the synchronous shaft 9 are provided with worm threads 14, and the synchronous shaft 9 is connected to the worm gear 13 through the worm threads 14. The clamping mechanism 7 includes a cylinder 701 and a V-shaped chuck 702, which is installed on the output end of the cylinder 701.

[0023] When clamping, the welding platform can adjust the distance between the two side clamping mechanisms 7 according to the length of the workpiece. During adjustment, the servo motor 10 is driven to run, which drives the synchronous shaft 9 to rotate. The worm gears 13 at the ends of the bidirectional lead screw guide rails 6 on both sides mesh with the worm threads 14 on the outer walls of the synchronous shaft 9 to drive the forward lead screw 602 and the reverse lead screw 603 to rotate. This causes the sliders on the forward lead screw 602 and the reverse lead screw 603 to move in opposite directions, so as to achieve the effect of synchronously adjusting the distance between the clamping mechanisms 7 on both sides of the bidirectional lead screw guide rails 6. After the distance is adjusted, the cylinder 701 of the clamping mechanism 7 is extended, and the V-shaped chuck 702 is used to clamp and fix the workpiece. After one side of the workpiece is welded, the drive motor 12 can be driven to run. Under the action of the belt drive mechanism, the welding clamping frame 5 is automatically flipped to facilitate the processing of the other side of the workpiece.

[0024] Please see Figure 3 A rubber pad 703 is provided on the end face of the V-type chuck 702, and the rubber pad 703 is bonded to the V-type chuck 702. The rubber pad 703 is an elastic material, which on the one hand avoids the V-type chuck 702 from directly contacting the workpiece and causing wear, and on the other hand, the rubber pad 703 can make the connection tighter and improve the clamping stability by relying on its elasticity.

[0025] Furthermore, a reinforcing rod is installed inside the fixing base 1. Multiple reinforcing rods are provided, and both ends of the reinforcing rods are welded to the fixing base 1.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
