[0023] 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.

[0024] Example 1: Please refer to Figures 1-3 A metal product manufacturing clamping device includes a fixed mounting plate 1 and lifting hydraulic rods 2 respectively fixedly mounted on both sides of the upper end of the fixed mounting plate 1. A connecting block 3 is fixedly mounted on one side of the upper end of the lifting hydraulic rod 2. A drive motor 4 is fixedly mounted on one end of the inner wall of the connecting block 3. A rotating double-headed screw 5 is mounted on one end of the drive motor 4. The other end of the rotating double-headed screw 5 is movably mounted to the other end of the inner wall of the connecting block 3.

[0025] When the drive motor 4 is turned on, the double-headed screw 5 rotates accordingly, causing the first moving support assembly 6 and the second moving support assembly 7 to move relative to each other along the connecting block 3. Then, the two sets of clamping assemblies 8 move to clamp the metal workpiece.

[0026] According to the prior art document CN218575974U, a metal product processing fixture, the drive motor 4, the rotating double-ended screw 5, the first moving support assembly 6, and the second moving support assembly 7 in this solution are an integrated structure of the metal product workpiece clamping device, drive motor, and rotating double-ended screw in the prior art document.

[0027] The upper end of the rotating double-ended screw 5 is threadedly connected to the first movable support assembly 6 and the second movable support assembly 7 respectively. The clamping assembly 8 is fixedly installed on one side of the upper end of the first movable support assembly 6 and the second movable support assembly 7 respectively. The clamping assembly 8 is set to be suitable for clamping and fixing the metal workpiece. The lifting assembly 9 is fixedly installed in the middle of one end of the outer wall of the fixed mounting plate 1. The lifting assembly 9 is set to be suitable for supporting the lower end of the metal workpiece that needs to be clamped and fixed.

[0028] The clamping assembly 8 includes a mounting mechanism 81 and an adjustment mechanism 82 threadedly connected to one side of the upper end of the mounting mechanism 81. A pre-fixing mechanism 83 is installed at the upper limit of the adjustment mechanism 82. The adjustment mechanism 82 is configured to drive the pre-fixing mechanism 83 to adjust its position up and down.

[0029] The first movable support assembly 6 includes a first support block 61 and a first right-angle block 62 fixedly installed at the middle of the upper end of the first support block 61. A rotary motor 63 is fixedly installed at the middle of one end of the inner wall of the first right-angle block 62.

[0030] The second movable support assembly 7 includes a second support block 71 and a second right-angle block 72 fixedly installed at the middle of the upper end of the second support block 71. A driven shaft 73 is movably installed at the middle of one end of the inner wall of the second right-angle block 72.

[0031] One end of the rotary motor 63 is equipped with a clamping component 8 via a movable shaft, and the other end of the driven shaft 73 is also equipped with a clamping component 8. After the workpiece is clamped and fixed by the clamping component 8, starting the rotary motor 63 can directly drive the clamping component 8 and the driven shaft 73 to rotate together, thereby realizing the rotation of the metal workpiece.

[0032] The erection mechanism 81 includes an L-shaped support plate 811 and a sliding groove 812 opened on one side of the upper end of the L-shaped support plate 811. Limiting grooves 813 are opened on both sides of the inner wall of the sliding groove 812. The threaded rod 822 is movably installed in the inner cavity of the sliding groove 812, and the second round block 824 is movably installed in the inner cavity of the limiting groove 813.

[0033] The adjusting mechanism 82 includes a partition plate 821 and a threaded rod 822 fixedly installed at the middle of one end of the outer wall of the partition plate 821. A first round block 823 is fixedly installed at one end of the threaded rod 822, and the first round block 823 is movably installed on one side of the groove opening of the sliding groove 812.

[0034] A second round block 824 is fixedly installed near the middle of one end of the threaded rod 822. Through round grooves 825 are respectively opened on both sides of the upper end of the partition plate 821. The other end of the threaded rod 822 is connected to a nut by thread on its outer surface. The nut presses the threaded rod 822 into the other side of the groove of the sliding groove 812 for fixing, thereby completing the setting height fixing of the partition plate 821.

[0035] The lifting assembly 9 includes an electric telescopic column 91 and a flat support plate 92 fixedly installed at the middle of the upper end of the electric telescopic column 91. The electric telescopic column 91 is configured to drive the flat support plate 92 to adjust the height.

[0036] In this embodiment: When the operator clamps the metal workpiece, the electric telescopic column 91 first drives the flat support plate 92 to rise to the same level as the L-shaped support plate 811. The flat support plate 92 supports one end of the metal workpiece. Then, the drive motor 4 drives the rotating double-headed screw 5 to rotate, thereby driving the first moving support assembly 6 and the second moving support assembly 7 to move relative to each other along the connecting block 3. When the two sets of clamping assemblies 8 move to the clamping width, the metal workpiece is placed on the upper end of the L-shaped support plate 811. The setting height of the threaded rod 822 in the inner cavity of the sliding groove 812 is directly adjusted according to the height of the metal workpiece. This allows the threaded rod 822 to drive the middle partition plate 821 and the pre-fixing mechanism 83 to adjust the setting height together. After the height is determined, the threaded rod 822 is threaded and pressed into one side of the groove opening of the sliding groove 812 by the nut, thereby fixing the position of the middle partition plate 821. This setting allows the L-shaped support plate 811 to adaptably clamp and fix metal workpieces of different heights.

[0037] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 4 The pre-fixing mechanism 83 includes a contact plate 831 and an elastic element 832 fixedly installed in the middle of the upper end of the contact plate 831, wherein the upper end of the elastic element 832 is fixedly installed in the middle of the lower end of the partition plate 821.

[0038] Guide rods 833 are fixedly installed on both sides of the upper end of the contact plate 831, and the guide rods 833 are movably installed in the inner cavity of the through circular groove 825.

[0039] A hollow pull block 834 is fixedly installed on the upper end of the guide rod 833. The hollow pull block 834 is designed to drive the guide rod 833 and the contact plate 831 to move, thereby causing the elastic element 832 fixedly installed in the middle of the upper end of the contact plate 831 to be compressed or extended.

[0040] In this embodiment: the operator pulls the hollow pull block 834 to drive the guide rod 833 and the contact plate 831 to rise, causing the elastic element 832 fixedly installed in the middle of the contact plate 831 to retract. After placing the side of the metal workpiece on the upper end of the L-shaped support plate 811, the hollow pull block 834 is loosened, so that the contact plate 831 automatically pre-fixes the side of the metal workpiece under the action of elasticity. This setting makes it easy for the operator to adjust and confirm the clamping position of the metal workpiece. After the position is determined, the metal workpiece is fixed by the moving adjustment mechanism 82.

[0041] Working principle: The electric telescopic column 91 drives the flat support plate 92 to rise to the same horizontal height as the L-shaped support plate 811. The flat support plate 92 supports one end of the metal workpiece. The drive motor 4 drives the rotating double-headed screw 5 to rotate, thereby driving the first moving support assembly 6 and the second moving support assembly 7 to move relative to each other along the connecting block 3. When the two sets of clamping assemblies 8 move to the clamping width, they pull the hollow pull block 834, causing the guide rod 833 and the contact plate 831 to rise. This causes the elastic element 832, which is fixedly installed in the middle of the contact plate 831, to retract, thus holding the metal workpiece... After the side is placed on the upper end of the L-shaped support plate 811, the hollow pull block 834 is loosened, so that the contact plate 831 can automatically pre-fix the side of the metal workpiece under the action of elasticity. After determining the clamping position of the metal workpiece, the setting height of the threaded rod 822 in the inner cavity of the sliding groove 812 is adjusted according to the height of the metal workpiece. This allows the threaded rod 822 to drive the middle partition plate 821 and the pre-fixing mechanism 83 to adjust the setting height together. After the height is determined, the threaded rod 822 is threaded and pressed into one side of the groove opening of the sliding groove 812 by the nut, so that the middle partition plate 821 can be fixed and adjusted.
