A control panel 5 is arranged on the operating table 4. A display screen is arranged on the control panel 5. Several sets of sliding grooves 6 are arranged in a circular array on the top of the processing table 1.

[0026] For example, such as Figure 2 As shown, each set of slide grooves 6 is equipped with a set of first fixing rods 7, and each set of first fixing rods 7 is movably sleeved with a set of sliders 8. The sliders 8 slide within the slide grooves 6. Each set of sliders 8 has a set of first mounting blocks 9 installed at its bottom. Several sets of first mounting blocks 9 are arranged in a circular array directly below the processing table 1. Each set of first mounting blocks 9 has a set of first mounting cavities 10 at its bottom. Each set of first mounting cavities 10 has a set of second fixing rods 11 installed within it. A cylinder 12 is installed at the center of the bottom of the processing table 1. The cylinder 12... A connecting block 13 is installed on the output end. Several sets of second mounting blocks 14 are installed in a circular array on the outer wall of the connecting block 13. Each set of second mounting blocks 14 has a set of second mounting cavities 15 at the end away from the connecting block 13. Each set of second mounting cavities 15 has a set of third fixing rods 16 installed in it. Several sets of connecting plates 17 are arranged in a circular array directly below the processing table 1. One end of each set of connecting plates 17 is movably sleeved on one set of second fixing rods 11, and the other end of each set of connecting plates 17 is movably sleeved on one set of third fixing rods 16.

[0027] For example, such as Figure 2 and Figure 3As shown, each set of sliders 8 has two sets of limiting posts 18 symmetrically installed on its top. Each set of limiting posts 18 has a set of threaded holes 19 at its top center. Several sets of moving blocks 20 are arranged in a circular array above the processing table 1. The bottom of each set of moving blocks 20 slides against the top of one set of sliders 8. Each set of moving blocks 20 has two sets of through holes 21 symmetrically opened on its top. The two sets of limiting posts 18 are respectively placed within the two sets of through holes 21, with the outer wall of the limiting posts 18 sliding against the inner wall of the through holes 21. Two sets of screws 22 are symmetrically arranged directly above each moving block 20, with the output end of each set of screws 22 threaded. Each set of movable blocks 20 has several sets of limiting holes 23 arranged in a rectangular array on the outer wall of each set of movable blocks 20, and a set of clamping plates 24 is provided at one end of each set of movable blocks 20. A set of protective pads 25 is installed on the side wall of each set of clamping plates 24 away from the movable blocks 20. Several sets of limiting rods 26 are installed in a rectangular array on the side wall of each set of clamping plates 24 close to the movable blocks 20. The other end of each set of limiting rods 26 passes through one set of limiting holes 23. A set of springs 27 is provided on each set of limiting rods 26. The two ends of each set of springs 27 are respectively installed on the side walls of the clamping plates 24 and the movable blocks 20 that are close to each other.

[0028] Working principle: The top of the processing table 1 is provided with multiple sets of sliding grooves 6. A first fixed rod 7 is installed in the sliding groove 6. The slider 8 slides in the sliding groove 6 by being movably sleeved on the first fixed rod 7. The bottom of the slider 8 is connected to a first mounting block 9. A second fixed rod 11 is provided in the first mounting block 9 for connecting the subsequent transmission mechanism. The cylinder 12 is located at the bottom center of the processing table 1. Its output end is connected to a connecting block 13. A second mounting block 14 is installed on the outer wall of the connecting block 13. A third fixed rod 16 is provided in the second mounting block 14. The two ends of the connecting plate 17 are movably sleeved on the second fixed rod 11 and the third fixed rod 16 respectively to form a linkage structure.

[0029] The hardware parts are placed on the top of the processing table 1. The cylinder 12 is started to lower the connecting block 13 and the second mounting block 14. The second mounting block 14 tilts the connecting plate 17 and moves the first mounting block 9. The first mounting block 9 moves the slider 8 into the slide groove 6 and moves the moving block 20. The moving block 20 moves the clamping plate 24 and the protective pad 25 to clamp and fix the hardware parts. The cylinder 12 is started again to raise the connecting block 13, so that the moving block 20 moves and moves the clamping plate 24 and the protective pad 25 away from the hardware parts, releasing the hardware parts.

[0030] When the clamping plate 24 contacts the hardware, the limiting rod 26 provides a certain buffering force under the action of the spring 27 to avoid damage to the workpiece during clamping. The protective pad 25 further protects the surface of the workpiece to prevent scratches or deformation. The circular array layout makes this clamping fixture suitable for hardware parts of various shapes and sizes.

[0031] Rotating screw 22 removes it from threaded hole 19, which moves the movable block 20 upward so that the limiting post 18 is removed from through hole 21. The movable block 20 is separated from slider 8, and a new movable block 20 can be placed on top of slider 8. After the limiting post 18 passes through the movable block 20, rotating screw 22 connects it to the threaded hole 19, fixing the movable block 20 on slider 8.

[0032] With its circular array of grooves 6 and adjustable clamping components, this clamping fixture can accommodate hardware fittings of various shapes and sizes, making it more flexible in handling workpieces of different specifications.

[0033] When the clamping plate 24 comes into contact with the hardware, the limiting rod 26 provides a certain buffering force under the action of the spring 27 to avoid damage to the workpiece during clamping. In addition, the design of the protective pad 25 further protects the surface of the workpiece, preventing scratches or deformation and ensuring the quality of the workpiece.

[0034] The starting cylinder 12 drives the connecting block 13 to descend, which in turn drives the second mounting block 14 to descend. The second mounting block 14 drives the connecting plate 17 to tilt, which in turn drives the first mounting block 9 to move. The first mounting block 9 drives the slider 8 to move within the slide groove 6, which in turn drives the moving block 20 to move. The moving block 20 drives the clamping plate 24 to move, which in turn drives the protective pad 25 to move, thus clamping and fixing the hardware accessories. The position and clamping range of the clamping plate 24 can be flexibly adjusted, which is suitable for hardware accessories of various shapes and sizes, reducing limitations and improving applicability.

[0035] Rotating screw 22 removes it from threaded hole 19, allowing the movable block 20 to move upwards, causing the limiting post 18 to be removed from through hole 21. Separation of movable block 20 from slider 8 allows a new movable block 20 to be placed on top of slider 8. After the limiting post 18 passes through movable block 20, rotating screw 22 threadedly connects it to threaded hole 19, fixing movable block 20 to slider 8. The clamping components can be replaced according to wear and tear and needs, which improves the versatility of the equipment, facilitates maintenance and repair, and reduces operating costs.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
