The clamping assembly 3 comprises a guide groove 301, which is opened inside the top of the clamping seat 1, a movable seat 306 is installed inside the guide groove 301, a clamping plate 302 is installed on the top of the movable seat 306, a spring 305 is installed on one side of the movable seat 306, and one end of the spring 305 is fixed to one side of the inside of the guide groove 301; a connecting frame 307 is installed at the bottom end of the movable seat 306, a fixed seat 308 is installed at the bottom end of the connecting frame 307, a connecting plate 304 is installed at the bottom end of the fixed seat 308, a cylinder 303 is fixed to the bottom end of the connecting plate 304, an ejector rod 309 is installed at the top of the connecting plate 304, and the cylinder 303 is fixed to the bottom end of the clamping seat 1;

[0036] One end of the connecting frame 307 is hinged to the bottom end of the movable base 306 , and the other end of the connecting frame 307 is hinged to the fixed base 308 ;

[0037] There are four groups of clamping plates 302, and the four groups of clamping plates 302 are symmetrically distributed on the four sides of the metal plate 4;

[0038] An auxiliary structure 5 is provided on one side of the clamping plate 302. The auxiliary structure 5 includes a slot 503. The slot 503 is provided inside one side of the clamping plate 302. A clamping block 502 is inserted into the slot 503. A rubber plate 501 is fixed to one side of the clamping block 502.

[0039] The mounting structure 2 includes a mounting plate 201 fixed to both sides of the clamping base 1. The mounting plate 201 has a through slot 203 formed therein, into which a fixing bolt 202 is inserted. The through slot 203 is provided in two groups, and the two groups of through slots 203 are symmetrically distributed within the mounting plate 201.

[0040] Reference Figure 1 - Figure 8 As shown: before clamping the metal plate 4, the clamping seat 1 is installed inside the machining center. During installation, the clamping seat 1 is installed inside the machining center, and then the through slot 203 is aligned with the reserved fixing hole. After alignment, the fixing bolt 202 is inserted through the through slot 203 into the reserved fixing hole for fixing, thereby completing the installation of the clamping seat 1. When the clamping seat 1 is installed, the metal plate 4 is placed on the top of the ejector rod 309. After placement is completed, the cylinder 303 is started to move downward. The cylinder 303 will drive the connecting plate 304 and the ejector rod 309 to move downward during the downward movement. As the ejector rod 309 moves downward, the metal plate 4 is placed on the top of the clamping seat 1. When the metal plate 4 is placed on the top of the clamping seat 1, as the connecting plate 304 continues to move downward, the connecting plate 304 will pull the connecting frame 307 downward through the fixing seat 308, and the connecting frame 307 moves downward. When the cam 306 is in the process of being moved, the movable seat 306 will be pulled to one side, and the movable seat 306 will move to one side under the guidance of the guide groove 301 when moving. When the movable seat 306 moves, the spring 305 will be pulled to contract, and when the rubber plate 501 on one side of the clamping plate 302 is in contact with one side of the metal plate 4, it stops moving. By using four sets of clamping plates 302, the metal plate 4 can be clamped on four sides at the same time, so that the metal plate 4 can be centered during the clamping process, thereby completing the centering clamping of the metal plate 4, making the metal plate 4 more accurate when clamping and fixing, thereby completing the clamping work of the metal plate 4. When the metal plate 4 is processed, the cylinder 303 is started to push upward, so that the clamping plate 302 releases the clamping of the metal plate 4, and the metal plate 4 can also be lifted up by the ejector rod 309, making it more convenient for the staff to take the processed metal plate 4.

[0041] An auxiliary structure 5 is provided on one side of the clamping plate 302. The auxiliary structure 5 includes a slot 503, which is provided inside one side of the clamping plate 302. A clamping block 502 is inserted into the slot 503, and a rubber plate 501 is fixed to one side of the clamping block 502. A rolling groove 504 is provided at the bottom end of the clamping plate 302. Balls 505 are installed inside the rolling groove 504. The balls 505 are connected in a rolling manner inside the rolling groove 504. Four groups of rubber plates 501 are provided. The rubber plates 501 are made of rubber. The clamping block 502 is inserted into the slot 503, and a clamping structure is formed between the clamping block 502 and the slot 503.

[0042] Reference Figure 8 - Figure 9 As shown: before the clamping plate 302 is clamped, the block 502 at one end of the rubber plate 501 is aligned with the slot 503, and after alignment, the block 502 is inserted into the inside of the slot 503, thereby completing the installation of the rubber plate 501. After the rubber plate 501 is installed, when the clamping plate 302 is clamping the metal plate 4, the rubber plate 501 can play a protective role, preventing the clamping plate 302 from causing damage to the metal plate 4 during the process of clamping the metal plate 4, thereby completing the protection work, and the clamping plate 302 will cause the ball 505 to rotate inside the rolling groove 504 during the movement, thereby reducing the friction between the clamping plate 302 and the surface of the clamping seat 1, making the clamping plate 302 more labor-saving during the movement.
