Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a workpiece turning device for machining. Background Technique

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. It can be divided into cutting machining and pressure processing according to the difference in processing methods. The production process of a machine refers to the whole process of manufacturing a product from raw materials (or semi-finished products). For machine production, it includes the transportation and storage of raw materials, production preparation, blank manufacturing, machining and heat treatment of parts, assembly and commissioning of products, painting and packaging, etc. The content of the production process is very extensive. Modern enterprises use the principles and methods of systems engineering to organize and guide production, regarding the production process as a production system with inputs and outputs. In the production process, any process that changes the shape, size, position and properties of the production object to make it a finished product or semi-finished product is called a process. It is the main part of the production process. The process can be further divided into casting, forging, stamping, welding, machining, assembly and other processes. The mechanical manufacturing process generally refers to the sum of the machining process of parts and the assembly process of machines, and other processes are called auxiliary processes, such as transportation, storage, power supply, turning, etc.

[0003] In the production process of machining, there are numerous workpieces that need to be turned over for processing. Therefore, workers often need to turn the workpieces back and forth during processing. For the processing of small batches of workpieces, the auxiliary processing time is still acceptable. However, when the batch is large, especially when a large number of sheet workpieces need to be turned over, if workers still rely on turning them back and forth, the accumulated auxiliary processing time will be very long. When this is added to the cost of the workpiece, the economic cost will undoubtedly increase significantly. Therefore, the importance of reducing the auxiliary processing time and improving the processing efficiency is self-evident.

[0004] To solve the above problems, we propose a workpiece turning device for machining to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present application are to solve the problems in the above background technology, and the general idea is as follows:

[0024] Embodiment: Refer to Figures 1-6 As shown, a turning-over device for machining in this embodiment includes a support base 1. There are two groups of support bases 1, which are distributed oppositely. A turning-over mechanism is provided at the upper ends of the inner sides of the two groups of support bases 1. The turning-over mechanism includes a lower clamping plate 2 and an upper clamping plate 3. Storage cavities 8 are provided in the middle of the inner sides of the lower clamping plate 2 and the upper clamping plate 3. A roller assembly 9 is provided in the middle of the inner side of the storage cavity 8. Four groups of fixed suction cups 10 are also provided in the middle of the inner side of the storage cavity 8. The four groups of fixed suction cups 10 are provided in the middle of the inner side of the roller assembly 9 and are distributed at the four corners of the inner side of the storage cavity 8. A first cylinder 11 is provided in the middle of the bottom end of the fixed suction cup 10.

[0025] A driving component is arranged at the side end of the flipping mechanism. The driving component is arranged in the middle inside of the support base 1 and is used to drive the flipping mechanism to perform rotational motion. The driving component includes a rotating shaft 5. The rotating shaft 5 is fixedly installed at the middle parts of both ends of the lower clamping plate 2. The end of the rotating shaft 5 is rotatably installed in the middle inside of the support base 1. Among them, a secondary driving gear 6 is arranged at the end of one rotating shaft 5. The secondary driving gear 6 is in transmission connection with a primary driving gear 7. The primary driving gear 7 is driven by a servo motor. By driving with the servo motor, the primary driving gear 7 is driven to rotate, thereby driving the secondary driving gear 6 and the rotating shaft 5 to perform rotational motion.

[0026] The upper clamping plate 3 is horizontally arranged at the middle upper end of the lower clamping plate 2 and is connected by four hydraulic rods 4. The four hydraulic rods 4 are all arranged at the four corner positions of the inner end faces of the lower clamping plate 2 and the upper clamping plate 3.

[0027] Among them, the material plate to be flipped is conveyed to the inlet end of the lower clamping plate 2 through the feeding mechanism, and then the material plate is continuously conveyed into the interior of the placing cavity 8 through the roller assembly 9 and then stops.

[0028] At this time, then start the four hydraulic rods 4. Under the retraction of the hydraulic rods 4, the upper clamping plate 3 is driven to descend. When the upper clamping plate 3 and the lower clamping plate 2 are closed, the upper and lower ends of the material plate can be limited, and then by rotating the lower clamping plate 2, the material plate can be flipped.

[0029] Among them, the first cylinder 11 is used to push the fixed suction cup 10 to drive the fixed suction cup 10 to move up and down. The upper and lower end faces of the material plate can be clamped and fixed by multiple fixed suction cups 10, so as to maintain the stability when the flipping mechanism is flipped.

[0030] After the material plate completes the flipping work, at this time the upper clamping plate 3 moves to the lower side and the lower clamping plate 2 moves to the upper side. Then start the four hydraulic rods 4 to separate the upper clamping plate 3 and the lower clamping plate 2. Then drive the fixed suction cup 10 to retract through the first cylinder 11, removing the restriction on the material plate, so as to facilitate starting the roller assembly 9 to convey the material plate out from the upper clamping plate 3.

[0031] In addition, limiting components are arranged at the middle parts of both ends of the lower clamping plate 2, including two limiting holes 12. The two limiting holes 12 are respectively opened at both ends of the lower clamping plate 2. A limiting rod 13 is inserted at the middle part of the inner side of the limiting hole 12. The limiting rod 13 is driven by a second cylinder 14 to drive it to slide in the horizontal direction. The limiting rod 13 is slidably installed in the middle inside of the support base 1. The second cylinder 14 is arranged in the middle inside of the support base 1. The output end of the second cylinder 14 is fixedly connected to the bottom end of the limiting rod 13.

[0032] Since the rotating shaft 5 is installed at both ends of the lower clamping plate 2, and the upper clamping plate 3 is located above the lower clamping plate 2, the center of gravity of the entire flipping mechanism is offset. In order to improve the stability of the flipping mechanism during feeding and avoid the situation of shaking caused by unstable center of gravity, the lower clamping plate 2 can be limited by setting a limiting component, thereby improving the stability of the material plate during conveying and feeding. Among them, it is driven by the second cylinder 14 to drive the limiting rod 13 to slide horizontally, so that the limiting rod 13 is inserted into the limiting hole 12, thereby realizing the limiting and fixing of the lower clamping plate 2, and enabling the roller assembly 9 to drive the material plate for stable conveying.

[0033] In some instances, the driven gear 6, the driving gear 7 and the servo motor are all arranged in the middle inside of the support base 1.

[0034] The working principle of the present utility model is as follows:

[0035] When it is necessary to turn the material plate, first, the material plate is conveyed to the inlet end on one side of the lower clamping plate 2 through the feeding mechanism. When the material plate is conveyed onto the roller assembly 9 inside the lower clamping plate 2, the roller assembly 9 can continue to convey the material plate into the placement cavity 8 inside the lower clamping plate 2;

[0036] Then, the hydraulic rod 4 drives the upper clamping plate 3 to descend, so that the upper clamping plate 3 and the lower clamping plate 2 are closed, thereby realizing the limitation of the material plate. At the same time, by starting the first cylinder 11 to push the fixed suction cups 10, multiple groups of fixed suction cups 10 can clamp and fix the material plate from the upper and lower ends of the material plate;

[0037] After the material plate is fixed, at this time, the driving component is started to drive the flipping mechanism to flip 180 degrees, thereby realizing the turning of the material plate. Then, the hydraulic rod 4 is driven to separate the upper clamping plate 3 and the lower clamping plate 2, and the first cylinder 11 drives the fixed suction cups 10 to retract to the initial position. At this time, the material plate loses its limitation. Next, by starting the roller assembly 9 inside the upper clamping plate 3, the material plate can be conveyed out. The entire turning process realizes automatic operation without manual assistance, effectively improving the efficiency and stability of the turning process.

[0038] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
