Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, specifically a workpiece flipping device. Background Technology

[0002] Workpiece flipping devices are key equipment in industrial production that connects multiple processing steps. In industrial production, workpieces such as steel plates, molds, and mechanical parts often need to be processed on both sides. With the large-scale development of industries such as automobile manufacturing, construction machinery, and steel structure processing, workpieces are becoming larger, heavier, and more precise. Manual flipping can no longer meet production needs, and there is a great need for automated flipping equipment to adapt to the requirements of batch production and high-precision processing. Workpiece flipping devices need to work in conjunction with machine tools, robots, conveyor lines, and other equipment to achieve continuous and unmanned processing.

[0003] There are many types of existing workpiece flipping devices, among which clamping flipping devices are widely used. However, the clamping force of the clamping jaws of clamping flipping devices is difficult to control precisely. If the clamping is too loose, the workpiece will slip off, and if it is too tight, the workpiece surface will be damaged. Therefore, a workpiece flipping device is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a workpiece flipping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A workpiece flipping device includes an operating table. Symmetrically arranged support plates are fixedly connected to the top of the operating table. Rotary shafts are rotatably connected inside the support plates. A stepper motor is fixedly connected to the outer side of the left support plate, and the output end of the stepper motor is fixedly connected to the rotating shaft. A fixing frame is fixedly connected between the two rotating shafts. A hydraulic rod is fixedly connected to the inner side of the fixing frame. A first fixing plate is fixedly connected to the bottom end of the hydraulic rod. A first rubber layer is fixedly connected to the bottom end of the first fixing plate. A support rod located below the first rubber layer is fixedly connected to the inner side of the fixing frame. The top of the support rod... A second fixing plate is fixedly connected to the end of the first fixing plate. A second rubber layer is fixedly connected to the top of the second fixing plate. A first electromagnet layer located outside the support rod is fixedly connected to the bottom of the second fixing plate. A second electromagnet layer located above the first fixing plate is fixedly connected to the inner side of the fixing frame. A metal limiting rod penetrating the first fixing plate, the first rubber layer, the second rubber layer, and the second fixing plate is magnetically connected to the top of the first electromagnet layer. A first buffer layer located between the metal limiting rod and the first electromagnet layer is fixedly connected to the bottom of the metal limiting rod. A second buffer layer is fixedly connected to the top of the metal limiting rod.

[0007] Preferably, the metal limiting rod, the first buffer layer, and the second buffer layer are a group, and there are several groups in total. The metal limiting rod, the first buffer layer, and the second buffer layer are uniformly arranged in a matrix inside the first fixed plate, the first rubber layer, the second rubber layer, and the second fixed plate.

[0008] Preferably, the shapes of the internal holes of the first fixing plate, the first rubber layer, the second rubber layer, and the second fixing plate match the outer shape of the metal limiting rod, all being cylindrical, and the inner sides of the internal holes of the first fixing plate, the first rubber layer, the second rubber layer, and the second fixing plate are in contact with each other.

[0009] Preferably, the hydraulic rods and support rods are arranged in a group, with a total of four groups. The hydraulic rods and support rods are symmetrically arranged on the inner side of the fixed frame, and the hydraulic rods and support rods are respectively located at the four corners of the first fixed plate and the second fixed plate.

[0010] Preferably, the spacing between the two support plates matches the overall length of the fixing frame, and the two ends of the fixing frame are in contact with the support plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) In this utility model, by setting the stepper motor, the first fixed plate, the first rubber layer, the second fixed plate, the second rubber layer, the metal limiting rod, the first electromagnet layer and the second electromagnet layer and other components, the workpiece can be matched with the shape of the workpiece to limit the workpiece, which can effectively prevent the clamped workpiece from falling off, and at the same time protect the surface of the workpiece to prevent the surface of the workpiece from being scratched. This solves the problem that there are many types of existing workpiece flipping devices, among which the clamping flipping device is widely used. However, the clamping force of the clamping flipping device is difficult to control accurately. If the clamping is too loose, it will easily slip off, and if it is too tight, it will damage the surface of the workpiece.

[0013] (2) In this utility model, the first buffer layer and the second buffer layer can buffer the metal limit rod during use, so as to avoid the metal limit rod from damaging the first electromagnet layer and the second electromagnet layer that it cooperates with. At the same time, the multiple sets of metal limit rods can be used for workpieces of various sizes and shapes, and the compatibility is stronger. Attached Figure Description

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A workpiece flipping device includes an operating table 1. Symmetrically arranged support plates 2 are fixedly connected to the top of the operating table 1. A rotating shaft 3 is rotatably connected inside the support plate 2. A stepper motor 4 is fixedly connected to the outer side of the left support plate 2, and the output end of the stepper motor 4 is fixedly connected to the rotating shaft 3. A fixing frame 5 is fixedly connected between the two rotating shafts 3. A hydraulic rod 6 is fixedly connected to the inner side of the fixing frame 5. A first fixing plate 7 is fixedly connected to the bottom end of the hydraulic rod 6. A first rubber layer 8 is fixedly connected to the bottom end of the first fixing plate 7. A support rod 9 located below the first rubber layer 8 is fixedly connected to the inner side of the fixing frame 5. A second fixing rod 9 is fixedly connected to the top end of the support rod 9. The top of the second fixed plate 10 is fixedly connected to a second rubber layer 11, and the bottom of the second fixed plate 10 is fixedly connected to a first electromagnet layer 12 located outside the support rod 9. The inner side of the fixing frame 5 is fixedly connected to a second electromagnet layer 13 located above the first fixed plate 7. The top of the first electromagnet layer 12 is magnetically connected to a metal limiting rod 14 that penetrates the first fixed plate 7, the first rubber layer 8, the second rubber layer 11, and the second fixed plate 10. The bottom of the metal limiting rod 14 is fixedly connected to a first buffer layer 15 located between the metal limiting rod 14 and the first electromagnet layer 12. The top of the metal limiting rod 14 is fixedly connected to a second buffer layer 16.

[0024] The metal limiting rod 14, the first buffer layer 15, and the second buffer layer 16 form a group, and there are several groups in total. The metal limiting rod 14, the first buffer layer 15, and the second buffer layer 16 are uniformly arranged in a matrix inside the first fixing plate 7, the first rubber layer 8, the second rubber layer 11, and the second fixing plate 10, which can stably limit workpieces of various shapes and sizes. The shape of the holes inside the first fixing plate 7, the first rubber layer 8, the second rubber layer 11, and the second fixing plate 10 matches the outer shape of the metal limiting rod 14, and are all cylindrical. The inner side of the hole inside the fixing plate 10 and the outer side of the metal limiting rod 14 fit together, which makes the movement of the metal limiting rod 14 more stable and avoids shaking, thus affecting the workpiece's limiting stability. The hydraulic rod 6 and the support rod 9 are a group, with a total of four groups. The hydraulic rod 6 and the support rod 9 are symmetrically arranged on the inner side of the fixing frame 5. The hydraulic rod 6 and the support rod 9 are respectively located at the four corners of the first fixing plate 7 and the second fixing plate 10, which can provide a more stable clamping and support effect for the workpiece. The distance between the two support plates 2 matches the overall length of the fixing frame 5, and the two ends of the fixing frame 5 fit together with the support plates 2.

[0025] Workflow: When a workpiece flipping device is required, the entire system is powered externally, pressurized by an external hydraulic pump, and centrally controlled by an external PLC controller. First, the large workpiece to be flipped is placed on the surface of the second rubber layer 11. The PLC controller controls the second electromagnet layer 13 to close and the first electromagnet layer 12 to open. After the second electromagnet layer 13 closes, without magnetic attraction, the metal limit rod 14 descends under gravity. The metal limit rod 14 directly above the workpiece and the first buffer layer 15 will adhere to the workpiece. The metal limit rods 14 and the first buffer layer 15 around the workpiece will pass through the second rubber layer 11 and the second fixing plate 10 to contact the first electromagnet layer 12. The magnet layer 12 magnetically holds the metal limiting rod 14 in place. The metal limiting rod 14 around the workpiece effectively prevents the workpiece from falling off during the flipping process. Next, the hydraulic rod 6 is controlled to drive the first fixing plate 7 and the first rubber layer 8 to descend. By cooperating with the second fixing plate 10 and the second rubber layer 11, the workpiece is clamped. The first rubber layer 8 and the second rubber layer 11 can protect the surface of the workpiece and prevent scratches. The output end of the stepper motor 4 drives the rotating shaft 3 to rotate. The rotating shaft 3 drives the fixing frame 5 and the workpiece to rotate, achieving the flipping effect. After the flipping is completed, the first electromagnet layer 12 is closed and the second electromagnet layer 13 is opened to reset the metal limiting rod 14 for the next use.
