[0003] Existing metalworking fixtures mainly consist of a base, support legs, and a processing table. In use, metal plates are placed on the processing table and clamped and fixed using relevant fixtures. However, in actual use, when the metal plate needs to be flipped, the fixtures need to be loosened and the plate needs to be flipped manually. This manual operation may cause positional deviations and inaccurate positioning. In addition, manually flipping the plate is time-consuming, labor-intensive, and reduces work efficiency.
[0004] Therefore, a metalworking fixture is proposed to address the above problems. Utility Model Content

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Specific implementation examples are given below.
[0026] Please see Figure 1 - Figure 6 A metalworking fixture includes a base 1, with support legs 2 fixedly connected to the four corners of the bottom end of the base 1, and a processing table 3 fixedly connected to the top end of the base 1. A clamping mechanism 4 is provided on the inner surface of the base 1, and flipping mechanisms 5 are symmetrically arranged on the outer surface of the clamping mechanism 4. The clamping mechanism 4 includes a concave frame 41 slidably connected to the base 1, with two square plates 42 fixedly connected to the top end of the concave frame 41, and a connecting frame 43 fixedly connected to the bottom end of the concave frame 41. An electric cylinder 44 is fixedly connected to one side of the connecting frame 43, and cylindrical tubes 45 are fixedly connected to the inner surfaces of the two square plates 42. A second cylinder 46 is fixedly connected to the inner surface of the connecting frame 43. A piston rod 47, which is fixedly connected to one side of the electric cylinder 44, is slidably connected to the inner surface of the second cylinder 46. Two cylindrical blocks 45 are slidably connected to their inner surfaces. Sliding groove rods 49 are rotatably connected to the inner surfaces of the two cylindrical blocks 48. Clamping plates 410 are fixedly connected to the sides of the two sliding groove rods 49 that are close to each other. A threaded rod 412, which is threadedly connected to the concave frame 41, is rotatably connected to the inner surface of the base 1. A servo motor 413, which is fixedly connected to the base 1, is fixedly connected to one side of the threaded rod 412. The inner surface of the second cylinder 46... The surface of the first cylinder 45 is connected to the inner surface of the second cylinder 46 via a pipe. When it is necessary to clamp and fix the metal plate, the two sides of the metal plate are placed between the two clamping plates 410. Then, the electric cylinder 44 is activated, causing the piston rod 47 to slide on the inner surface of the second cylinder 46. Hydraulic oil in the inner cavity of the second cylinder 46 is transported to the inner cavities of the two cylinders 45 through the pipe. Under the action of hydraulic pressure, the two cylindrical blocks 48 move closer to each other, causing the clamping plates 410 on the two sliding rods 49 to press tightly against the two sides of the metal plate, thereby fixing the metal plate. Subsequently, the output of the servo motor 413 can be started to drive the threaded rod 412 to rotate through the coupling. Under the action of the threaded connection, the concave frame 41 and the square plate 42 are moved, thereby realizing the movement of the clamped metal sheet. The clamping plate 410 is made to fit tightly against both sides of the sheet through hydraulic means to ensure the stability of the sheet during processing and avoid displacement. Then, the servo motor 413 is used to drive the movement of related components, which can accurately control the position change of the sheet, realize efficient and precise processing, improve the processing quality and efficiency of sheet metal, adapt to different processing needs, and bring many conveniences to the processing of metal sheets.
[0027] The servo motor 413 mentioned above is a mature drive technology and device in the existing technology. In this solution, its output end can be rotated in both directions through a coupling. Its internal structure, principle and connection method will not be described further.
[0028] like Figure 5As shown, several rubber strips 411 are linearly and equidistantly distributed and fixedly connected to the inner surfaces of the two clamping plates 410. By setting the rubber strips 411, the friction between the clamping plates 410 and the metal plate can be increased, thereby facilitating the fixing of the metal plate.
[0029] like Figure 6 As shown, a circular hole 414 is provided on one side of the second cylinder 46. A cross silicone valve 415 is fixedly connected to the inner surface of the circular hole 414. By setting the cross silicone valve 415, air can be allowed to pass through while blocking external debris, so as to prevent debris from entering the inner cavity of the second cylinder 46.
[0030] like Figure 6 As shown, the flipping mechanism 5 includes a one-way bearing 51 slidably connected to the inner surfaces of two sliding rods 49. A fixing frame 54 is fixedly connected to the opposite side of each of the two square plates 42. Gears 52, which are fixedly connected to the outer surfaces of the two fixing frames 54, are rotatably connected to the outer surfaces of the one-way bearings 51. Two racks 53, meshing with the gears 52, are fixedly connected to the top of the base 1. When the metal plate on the other side needs to be flipped for processing, the threaded rod 412 drives the clamping plate 410 to move backward. When the gears 52 mesh with the racks 53, the gears 52 drive the sliding rods 49 to rotate 180 degrees via the one-way bearings 51, thereby changing the surface of the clamped metal plate. This allows for quick switching of the metal plate's processing surface, saving time and improving processing efficiency. The flipping process is precise and stable, ensuring the plate's positional accuracy after flipping and guaranteeing subsequent processing quality, meeting high-precision processing requirements. It eliminates the need for manual flipping of the plate, saving time and effort and improving work efficiency.
[0031] like Figure 6As shown, two discs 55 are fixedly connected to the outer surfaces of the two fixed brackets 54. Two springs 56 are fixedly connected to the side of the two discs 55 that are close to each other. One end of the springs 56 on the same side is fixedly connected to a locking block 57. The inner cavity of each of the four springs 56 is provided with a telescopic rod 510. The two ends of the four telescopic rods 510 are fixedly connected to one side of the disc 55 and one side of the locking block 57, respectively. Circular grooves 58 are opened on the side of the two discs 55 that are far from each other. The inner surface of each of the two circular grooves 58 is provided with a locking groove 59 that matches the size and shape of the outer surface of the locking block 57. When the sliding rod 49 rotates, it will drive the disc 55 to rotate, so that the locking block 57 on the disc 55 will rotate. Under the combined action of spring 56 and telescopic rod 510, the metal sheet slides on the inner surface of circular groove 58. After rotating 180 degrees, the two locking blocks 57 will be locked into the inner surface of locking groove 59 under the combined action of spring 56 and telescopic rod 510, thus fixing the metal sheet after flipping. At the same time, the automated flipping and fixing process ensures the positional accuracy of the metal sheet after flipping, avoiding positional deviations that may be caused by manual operation, thereby ensuring the quality of subsequent processing. Through the tight cooperation of the mechanical structure, the metal sheet can be firmly fixed during the flipping process, keeping it stable during processing, further improving the accuracy and reliability of processing, and meeting the requirements of high-precision processing.
[0032] The one-way bearing 51 mentioned above is a mature one-way rotating part in the prior art. In this solution, it is used to rotate in one direction and lock in the other direction. Its internal structure, principle and connection method will not be described further.
[0033] The working principle of this utility model is as follows: When it is necessary to clamp and fix a metal sheet, the two sides of the metal sheet are placed between two clamping plates 410. Then, the electric cylinder 44 is activated, causing the piston rod 47 to slide on the inner surface of the second cylinder 46. Hydraulic oil in the inner cavity of the second cylinder 46 is transported through pipes to the inner cavities of the two first cylinders 45. Under the action of hydraulic pressure, the two cylindrical blocks 48 move closer to each other, causing the clamping plates 410 on the two sliding rods 49 to press tightly against the two sides of the metal sheet, thereby fixing the metal sheet. Subsequently, the output end of the servo motor 413 can be activated to drive the threaded rod 412 to rotate through the coupling. Under the action of the threaded connection, the concave frame 41 and the square plate 42 move, thereby achieving the clamping of the metal sheet. The metal sheet is then manually processed. When it is necessary to flip the metal sheet to process the other side, the threaded rod 412 drives the clamping plate 410 to move backward. When the gear 52 meshes with the rack 53, the gear 52 will drive the sliding rod 49 to rotate 180 degrees through the one-way bearing 51, thereby changing the face of the clamped metal sheet. During the rotation, the sliding rod 49 will drive the disc 55 to rotate, so that the locking block 57 on the disc 55 slides on the inner surface of the circular groove 58 under the action of the spring 56 and the telescopic rod 510. After rotating 180 degrees, the two locking blocks 57 will be locked into the inner surface of the locking groove 59 under the action of the spring 56 and the telescopic rod 510, thereby fixing the metal sheet after the face change.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
