By energizing a coil, an attractive force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base. Because an electromagnetic clamping method is used, the pressure plate can be manufactured according to specific workpiece requirements. The operation is simple, and workpieces with side walls can be processed.
[0003] Chinese patent application CN201820451014.9 discloses a fixture for a CNC bending machine, including a base plate. First threaded tubes are fixedly connected to both sides of the top of the base plate. A housing is mounted on the top of the first threaded tubes, and the bottom of the housing contacts the first threaded tubes. A shell is fixedly connected to the central shaft at the bottom of the housing. A motor is fixedly connected to the inner cavity of the shell, and the output shaft of the motor passes through the inner cavity of the housing and is fixedly connected to a first gear. This invention solves the problems of inconvenient height adjustment and poor clamping effect for parts of different shapes in existing CNC bending machine fixtures by using the base plate, first threaded tubes, housing, shell, motor, first gear, second gear, first threaded rod, first clamping plate, slide rod, second clamping plate, second threaded tube, second threaded rod, and rotating handle. This CNC bending machine fixture is easy to use, improves the practicality of CNC bending machine fixtures, and is worthy of widespread use.
[0004] However, the existing fixtures still have some defects. They lack adjustment devices, cannot be applied to various types of bending machines, and have certain limitations, resulting in poor practicality. Utility Model Content

[0014] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.
[0015] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.
[0016] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0017] like Figures 1 to 5 As shown, a high-efficiency bending machine special precision fixture includes a base 1, a pair of lifting rods 2 are installed on the upper surface of the base 1, a second lifting rod 3 is provided on the inner side of the first lifting rod 2, a worktable 4 is installed at the top of the second lifting rod 3, a lifting mechanism 5 is provided between the lower surface of the worktable 4 and the base 1, an adjustment mechanism 6 is provided on the upper surface of the worktable 4, a slider 7 is provided on the adjustment mechanism 6, a first support plate 8 is installed on the slider 7, a fixing mechanism 9 is installed on the first support plate 8, and a storage box 10 is installed at the bottom of the worktable 4. The adjustment mechanism 6 includes a pair of fixed seats 601 fixedly installed on the upper surface of the worktable 4. A drive motor 602 is installed at one end of the fixed seat 601. A threaded rod 603 is connected to the output end of the drive motor 602. The two ends of the threaded rod 603 are threadedly connected to the slider 7. A guide rod 604 is connected to the inner side of the fixed seat 601. A first groove 605 matching the guide rod 604 is opened on the slider 7.
[0018] With the above scheme, the drive motor 602 is started, and its output end drives the threaded rod 603 to rotate. Since the threads at both ends of the threaded rod 603 are opposite, the two sliders 7 will move in opposite or the same direction at the same time. The movement of the sliders 7 drives the fixing mechanism 9 and the workpiece to move together through the first support plate 8, thereby realizing the precise adjustment and positioning of the workpiece. At the same time, the guide rod 604 matches the first groove 605 on the slider 7 to ensure the stability and accuracy of the slider 7 during the movement.
[0019] The fixing mechanism 9 includes a rectangular groove 901 formed on the first support plate 8, a threaded rod 902 threadedly connected to the rectangular groove 901, a rotating handle 903 fixedly installed at the top of the threaded rod 902, a pressure plate 904 threadedly connected to the threaded rod 902, a second sliding groove 905 formed on one side of the first support plate 8, one end of the pressure plate 904 slidably connected to the second sliding groove 905, and a second support plate 906 installed at the bottom of one side of the first support plate 8.
[0020] The rotating handle 903 provided by the above scheme allows the operator to easily adjust the height of the pressure plate 904 to meet the fixing requirements of different workpieces. In addition, the sliding connection design between one end of the pressure plate 904 and the second slide groove 905 not only increases the flexibility of fixing, but also ensures the stability of the workpiece during processing, effectively preventing processing errors caused by shaking, and enabling flexible clamping of workpieces of different sizes and shapes.
[0021] The lifting mechanism 5 includes a mounting base 501 fixedly mounted on the base 1. A second drive motor 502 is mounted on one end of the mounting base 501. A worm gear 503 is connected to the output end of the second drive motor 502. A second threaded rod 504 is rotatably connected to the upper surface of the base 1. A worm wheel 505 is connected to the bottom of the second threaded rod 504. A lifting cylinder 506 is fixedly connected to the lower surface of the worktable 4. The bottom end of the lifting cylinder 506 is threadedly connected to the top end of the second threaded rod 504.
[0022] With the above scheme, the second drive motor 502 is started, the worm gear 503 drives the worm wheel 505 to rotate, and then drives the second threaded rod 504 to rotate. Since the bottom end of the lifting cylinder 506 on the lower surface of the worktable 4 is threadedly connected to the top end of the second threaded rod 504, the rotation of the second threaded rod 504 will be converted into the lifting motion of the lifting cylinder 506, thereby driving the worktable 4 to rise and fall as a whole.
[0023] A drawer 1001 is fitted onto the front and side of the storage box 10.
[0024] With the above design, the storage box 10 is located at the bottom of the workbench 4 and is used to store tools, accessories, and other items. The drawer 1001 is fitted onto the side of the storage box 10, allowing operators to quickly access the required items. The threads at both ends of the threaded rod 603 are in opposite directions.
[0025] The usage process of this utility model patent is as follows: First, according to the usage requirements, start the second drive motor 502 to drive the worm gear 503 to rotate, which in turn drives the worm wheel 505 and the second threaded rod 504 to rotate. Since the second threaded rod 504 is threadedly connected to the lifting cylinder 506, the rotation of the second threaded rod 504 will be converted into the lifting motion of the lifting cylinder 506, thereby driving the worktable 4 to lift as a whole. Then, place the workpiece to be processed on the first support plate 8, adjust the position of the first support plate 8 according to the size and shape of the workpiece, and start the first drive motor 602 to drive the first threaded rod 603 to rotate. Since the threads at both ends of the threaded rod 603 are in opposite directions, the two sliders 7 will move in opposite directions simultaneously, or move in the same direction according to the rotation direction of the threaded rod 603. Hold the rotating handle 903 and rotate the threaded rod 902 clockwise, so that the pressure plate 904 slides down along the threaded rod 902 and fits against the workpiece surface. After the pressure plate 904 fits against the workpiece, continue to rotate the threaded rod 902, so that one end of the pressure plate 904 slides along the second groove 905 until the workpiece is firmly fixed on the first support plate 8. At this time, the second support plate 906 plays the role of supporting and stabilizing the pressure plate 904.
[0026] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
