[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a clamping fixture for hardware processing, such as... Figure 4 As shown, the clamping fixture 24 is mounted on the processing table 25. The clamping fixture 24 includes a fixture base plate 1, and a clamping assembly 2 for clamping metal workpieces is provided at the top of the fixture base plate 1. The clamping assembly 2 includes a core seat 3 fixedly mounted on the top of the fixture base plate 1 by screws. A lower core 4 is fixedly connected to the top of the core seat 3 by screws. A clamping lever seat 6 is connected to the top of the core seat 3 by a locking assembly 5. A clamping lever 7 is connected to the top of the clamping lever seat 6 by a pin. An upper core 8 connected to the clamping lever 7 is connected to the lower core 4 by a pin. A drive mechanism is mounted on the fixture base plate 1. The clamping lever 7 rotates around the pin, and the output shaft of the clamping cylinder 9 is connected to one end of the clamping lever 7 via a rotating shaft. When clamping a metal workpiece, when one end of the metal workpiece is placed between the lower clamping core 4 and the upper clamping core 8, the output shaft of the clamping cylinder 9 pushes the clamping lever 7 to rotate around the pin, so that the upper clamping core 8 moves along the pin and cooperates with the lower clamping core 4 to fix and clamp the metal workpiece. The clamping of the metal workpiece is achieved through the lever principle, which makes the clamping force greater and the clamping force more uniform, which can prevent the workpiece from loosening and make the clamping stability of the metal workpiece higher, thus ensuring the processing quality of the metal products.

[0024] The locking assembly 5 includes a square groove 10 that is formed at the top of the core seat 3 and matches the bottom of the clamping lever seat 6. The bottom of the clamping lever seat 6 is inserted into the square groove 10 on the core seat 3 and then locked by screws, which can connect the clamping lever seat 6 and the core seat 3.

[0025] The clamping lever seat 6 has an arc-shaped top end, and one end of the clamping lever 7 has a connecting hole 11 for the arc end of the clamping lever seat 6 to extend into and connect with the arc end of the clamping lever seat 6 through a pin. The clamping lever 7 has a connecting block 12 connected to the upper clamping core 8 at one end near the connecting hole 11. When the arc end of the clamping lever seat 6 is inserted into the connecting hole 11 of the clamping lever 7, the clamping lever seat 6 and the clamping lever 7 are connected by a pin, allowing the clamping lever 7 to rotate around the pin.

[0026] The fixture base plate 1 is provided with a material unloading and pushing assembly 13 for unloading. The material unloading and pushing assembly 13 includes a material unloading guide hole 14 opened in the middle of the clamping lever seat 6. A material unloading rod 15 that can move between the lower clamping core 4 and the upper clamping core 8 passes through the material unloading guide hole 14. The clamping fixture also includes a material unloading fixing plate 16. The top of the material unloading fixing plate 16 is screwed with a material unloading cylinder 17 that drives the material unloading rod 15 to move. The output shaft of the material unloading cylinder 17 is connected to a material unloading connecting plate 18. One end of the material unloading connecting plate 18 is provided with a material unloading push plate 1. 9. One end of the unloading push plate 19 is provided with an unloading fixing block 20 for fixing the unloading rod 15. The unloading connecting plate 18 is provided with a groove hole 23 for the output shaft of the clamping cylinder 9 to pass through. When unloading the finished hardware workpiece, the output shaft of the unloading cylinder 17 pushes the unloading connecting plate 18 to move, the unloading connecting plate 18 pushes the unloading push plate 19 to move, the unloading push plate 19 pushes the unloading fixing block 20 to move, and the unloading fixing block 20 moves along the unloading guide hole 14, so that the finished hardware workpiece between the upper clamping core 8 and the lower clamping core 4 can be pushed out, which is convenient for unloading.

[0027] One end of the unloading fixing plate 16 is fixedly connected to the top end of the clamping cylinder 9 by screws, and the unloading adapter plate 21 is connected to the top end of the clamping cylinder 9 by screws. The unloading adapter plate 21 has a through hole 22 for the output shaft of the clamping cylinder 9 to pass through.

[0028] During operation, when the hardware processing clamping fixture 24 clamps a hardware workpiece, with one end of the workpiece placed between the lower clamping core 4 and the upper clamping core 8, the output shaft of the clamping cylinder 9 pushes the clamping lever 7 to rotate around the pin. This causes the upper clamping core 8 to move along the pin and cooperate with the lower clamping core 4 to fix and clamp the hardware workpiece. The clamping of the hardware workpiece is achieved through the lever principle, resulting in a greater clamping force and a more uniform clamping force. This prevents the workpiece from loosening, making the clamping stability of the hardware workpiece higher and ensuring the processing quality of the hardware products.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
