Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a fixture for sheet metal welding. Background Technology

[0002] With the advancement of technology and the acceleration of industrialization, the application of sheet metal is becoming increasingly widespread. In the sheet metal processing, welding is a crucial step that directly affects the structural strength and overall quality of the product. To ensure the stability of the welding, special sheet metal welding fixtures are usually used to clamp and fix the sheet metal parts.

[0003] However, traditional sheet metal welding fixtures have obvious drawbacks. If welding is required on the other side of the clamped sheet metal part, it is often necessary to first loosen the fixture, flip the sheet metal part over, and then re-clamp and fix it. This process is not only cumbersome and time-consuming, but also greatly reduces the efficiency of welding work. To address these issues, we provide a sheet metal welding fixture. Utility Model Content

[0004] The problem to be solved by this utility model is to provide a sheet metal welding fixture that can quickly flip sheet metal parts after they have been clamped and fixed.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sheet metal welding fixture, including a mounting platform, two U-shaped frames are arranged above the mounting platform, and mounting frames are fixedly connected to the upper surfaces of the two U-shaped frames. A driving mechanism is installed inside the two mounting frames, and clamping plates are arranged on the adjacent sides of the two mounting frames. The driving mechanism includes a rotating shaft, which passes through the side surface of the mounting frame. One end of the rotating shaft is rotatably connected to the inner wall of the mounting frame, and the other end of the rotating shaft is fixedly connected to the corresponding clamping plate.

[0006] Preferably, in the above-mentioned sheet metal welding fixture, a motor is fixedly connected inside the mounting frame, a rotating rod is fixedly connected to the output end of the motor, the end of the rotating rod away from the motor is rotatably connected to the inner wall of the mounting frame, a worm gear is fixedly connected to the outer surface of the rotating rod, and a worm wheel is fixedly connected to the outer surface of the rotating shaft located inside the mounting frame, the worm wheel meshing with the worm gear.

[0007] Preferably, in the above-mentioned sheet metal welding fixture, an adjustment mechanism is installed inside the mounting platform. The adjustment mechanism includes a motor housing, which is fixedly connected to the right side of the mounting platform. A second motor is fixedly connected inside the motor housing. A second rotating shaft is fixedly connected to the output end of the second motor. The left end of the second rotating shaft passes through the right side of the mounting platform and extends into the interior of the mounting platform. A double-acting lead screw is fixedly connected to the left end of the second rotating shaft. The left end of the double-acting lead screw is rotatably connected to the inner wall of the mounting platform.

[0008] Preferably, in the above-mentioned sheet metal welding fixture, the surface of the bidirectional lead screw is threaded with two connecting blocks, and the interior of the mounting platform is fixedly connected with two limiting slide rods, and the two connecting blocks are slidably connected to the outer surfaces of the two limiting slide rods.

[0010] Preferably, in the above-mentioned sheet metal welding fixture, a control switch is installed on the front of the mounting platform, and four support legs are fixedly connected to the bottom of the mounting platform.

[0011] The advantages and beneficial effects of this utility model are:

[0012] This invention utilizes the coordination between a U-shaped frame, a drive mechanism, clamping plates, and a control switch. By simultaneously activating motors in both drive mechanisms via the control switch, and through the cooperation of corresponding rotating rods, worm gears, worm wheels, and rotating shafts, the two clamping plates can be rotated synchronously, thereby causing the clamped sheet metal parts to flip. This design enables rapid flipping of the sheet metal parts, making it easier to weld the other side of the sheet metal parts without frequent disassembly of the clamped sheet metal parts, greatly improving welding efficiency. Furthermore, the U-shaped frame increases the clamping height of the sheet metal parts, preventing them from hitting the mounting table during flipping.

[0013] This invention utilizes the cooperation between a U-shaped frame, clamping plates, an adjustment mechanism, a through slot, and a control switch. By starting the second motor via the control switch, and with the cooperation of the second rotating shaft, a two-way lead screw, a connecting block, a limit slide rod, and the through slot, the two U-shaped frames can be moved closer or further apart, thereby adjusting the distance between the two clamping plates. This design allows for flexible adjustment of the clamping distance according to the size of the sheet metal part, enabling stable clamping of sheet metal parts of different sizes and improving the stability of clamping sheet metal parts of different sizes.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1 to 4 As shown, a sheet metal welding fixture includes a mounting platform 1. Two U-shaped frames 2 are arranged above the mounting platform 1. Mounting frames 3 are fixedly connected to the upper surfaces of the two U-shaped frames 2. A drive mechanism 4 is installed inside the two mounting frames 3. Clamping plates 5 are arranged on the adjacent sides of the two mounting frames 3. The drive mechanism 4 includes a rotating shaft 404, which passes through the side surface of the mounting frame 3. One end of the rotating shaft 404 is rotatably connected to the inner wall of the mounting frame 3, and the other end of the rotating shaft 404 is fixedly connected to the corresponding clamping plate 5.

[0021] Two U-shaped frames 2 are symmetrically distributed above the mounting platform 1. The U-shaped frames 2 increase the clamping height of the sheet metal parts, which can prevent the sheet metal parts from hitting the mounting platform 1 during subsequent flipping. Two mounting frames 3 are fixedly connected to the upper surfaces of the two U-shaped frames 2. Two drive mechanisms 4 are installed inside the two mounting frames 3. The rotating shaft 404 is rotatably connected to the mounting frame 3. The drive mechanism 4 is started by the control switch 8, and the clamping plate 5 can be rotated by the rotating shaft 404.

[0022] A motor 401 is fixedly connected inside the mounting frame 3. A rotating rod 402 is fixedly connected to the output end of the motor 401. The end of the rotating rod 402 away from the motor 401 is rotatably connected to the inner wall of the mounting frame 3. A worm gear 403 is fixedly connected to the outer surface of the rotating rod 402. A worm wheel 405 is fixedly connected to the outer surface of the rotating shaft 404 located inside the mounting frame 3. The worm wheel 405 is meshed with the worm gear 403.

[0023] The motors 401 in the two drive mechanisms 4 are of the same specification and model. Therefore, the two motors 401 can be started simultaneously by the control switch 8. The motors 401 in the two mounting frames 3 are started simultaneously by the control switch 8. The output ends of the two motors 401 drive the corresponding rotating rods 402 and worm gears 403 to rotate respectively. Since the worm gear 403 is meshed with the worm wheel 405 on the rotating shaft 404, the rotation of the worm gear 403 will drive the worm wheel 405 and the rotating shaft 404 to rotate, which will in turn drive the two clamping plates 5 and the clamped sheet metal parts to flip.

[0024] An adjustment mechanism 6 is installed inside the mounting platform 1. The adjustment mechanism 6 includes a motor housing 601, which is fixedly connected to the right side of the mounting platform 1. A second motor 602 is fixedly connected inside the motor housing 601. A second rotating shaft 603 is fixedly connected to the output end of the second motor 602. The left end of the second rotating shaft 603 passes through the right side of the mounting platform 1 and extends into the interior of the mounting platform 1. A double-acting lead screw 604 is fixedly connected to the left end of the second rotating shaft 603. The left end of the double-acting lead screw 604 is rotatably connected to the inner wall of the mounting platform 1.

[0025] The motor housing 601 can protect the second motor 602. By controlling the switch 8 to start the second motor 602 in the regulating mechanism 6, the output end of the second motor 602 will drive the second shaft 603 to rotate, which in turn drives the bidirectional lead screw 604 to rotate.

[0026] The surface of the bidirectional lead screw 604 is threaded with two connecting blocks 605, and the interior of the mounting platform 1 is fixedly connected with two limiting slide rods 606. Both connecting blocks 605 are slidably connected to the outer surfaces of the two limiting slide rods 606.

[0027] Two connecting blocks 605 are symmetrically distributed on the outer surface of the bidirectional lead screw 604, and two limiting slide rods 606 are symmetrically distributed on both sides of the bidirectional lead screw 604. The two limiting slide rods 606 can limit and guide the two connecting blocks 605. Since the two connecting blocks 605 are threadedly connected to the bidirectional lead screw 604, when the bidirectional lead screw 604 rotates, the limiting and guiding effect of the two limiting slide rods 606 will cause the two connecting blocks 605 to move closer or further apart.

[0028] The upper surface of the mounting platform 1 has two through slots 7. The lower ends of the two U-shaped frames 2 are inserted into the two through slots 7 and extend into the interior of the mounting platform 1. The lower ends of the two U-shaped frames 2 are fixedly connected to the upper surfaces of the two connecting blocks 605 respectively.

[0029] The spacing between the two through slots 7 corresponds to the lower end of the U-shaped frame 2. The lower end of the U-shaped frame 2 passes through the interior of the two through slots 7 and is fixedly connected to the connecting block 605. Therefore, when the two connecting blocks 605 move, they will drive the two U-shaped frames 2 to move synchronously.

[0030] A control switch 8 is installed on the front of the mounting platform 1, and four support legs 9 are fixedly connected to the bottom of the mounting platform 1.

[0031] The drive mechanism 4 and adjustment mechanism 6 can be started by controlling switch 8. The four support legs 9 are distributed in a rectangular shape on the bottom surface of the mounting platform 1, which can provide stable support for the whole device, so that the device can maintain a stable working state when working.

[0032] Working principle: When using this device, the sheet metal part is placed between two clamping plates 5. The motor 602 is started via the control switch 8, which drives the rotating shaft 603 and the double-acting lead screw 604 to rotate. Since the double-acting lead screw 604 is threadedly connected to two connecting blocks 605 and the connecting blocks 605 are limited by two limiting slide rods 606, the two connecting blocks 605 move closer together. This, in turn, causes the two U-shaped frames 2, which are fixedly connected to the connecting blocks 605 via the through groove 7, to move closer together. Then, the two clamping plates 5 stably clamp the sheet metal part, and welding is then performed. Once the work is completed, when welding is required on the other side of the clamped sheet metal part, the two motors 401 in the mounting frames 3 are started simultaneously by controlling the switch 8. The output ends of the two motors 401 drive the corresponding rotating rods 402 and worm gears 403 to rotate respectively. Since the worm gear 403 is meshed with the worm wheel 405 on the rotating shaft 404, the rotation of the worm gear 403 will drive the worm wheel 405 and the rotating shaft 404 to rotate, which will in turn drive the two clamping plates 5 and the clamped sheet metal parts to flip over, and then the other side of the sheet metal parts can be welded.
