It can ensure that the aluminum profile is firmly fixed on the workbench or fixture during the processing process, so as to carry out cutting, drilling, milling and other processing operations. Aluminum is a metal element with the element symbol Al and the atomic number 13. Its single substance is a silvery white light metal. It is ductile. The product is often made into rods, sheets, foils, powders, strips and wires.

[0003] After searching, the Chinese patent document with the announcement number CN213730519U discloses a fixing clamping device for aluminum profile production, including a supporting leg, a box body is fixedly connected to the top of the supporting leg, a slot body is provided at both sides of the interior of the box body, a motor is arranged inside the slot body, a fixing plate is fixedly connected to the middle position of the top of the box body, gears are arranged at both sides of the top of the fixing plate, a connecting rod is arranged on one side of the gear, and a rack is arranged on one side of the connecting rod. In the utility model, when the aluminum profile is produced and processed, vibration will be generated due to the work, two rubber pads are arranged at the bottom of the supporting leg, a shell is arranged inside the box body, and a shock-absorbing spring, a sound-absorbing cavity, a film and a porous material are arranged inside the shell, and these materials are used to absorb the generated noise, and the sound-absorbing cotton arranged on both sides of the fixing plate can further absorb the noise on the top of the fixing plate, which is worthy of promotion.

[0004] The working principle of the above patent specification mentions that "when using the device, considering that the current tools cannot clamp and fix the aluminum well, motors 3 are arranged on both sides of the box body 22, and a fixing plate 7 is arranged on the top of the box body 22. The aluminum is placed on the top of the fixing plate 7, and the two motors 3 are started by using the gear 11, rack 10, connecting shaft 9 and connecting plate 12 on the top of the fixing plate 7.

A fixed plate 7 is fixedly connected to the middle of the operating table 1. A limiting sliding groove 21 is opened at the bottom of the fixed plate 7. A limiting block 22 is fixedly connected to the top of the moving plate 6. The outside of the limiting block 22 is slidably connected to the inner wall of the limiting sliding groove 21. At this time, the limiting blocks 22 at the tops of the two moving plates 6 will slide along the limiting sliding groove 21 at the bottom of the fixed plate 7. Connecting plates one are rotatably connected to the left and right sides of the bottom plate 2. The top of the connecting plate one is rotatably connected to the connecting plate 8. The other end of the connecting plate 8 is rotatably connected to a connecting plate two 9. One end of a limiting column 13 is fixedly connected to the bottom of the clamping plate 12.

[0027] The top of the connecting plate two 9 is rotatably connected to a connecting rod two 10. The other end of the connecting rod two 10 is rotatably connected to a connecting rod three 11. The other end of the connecting rod three 11 is rotatably connected to the clamping plate 12. At this time, the clamping plate 12 will also move accordingly. Limiting columns 13 are slidably connected inside both the connecting plate one and the connecting plate two 9, and the connecting plate one and the connecting plate two 9 are driven to slide on the outside of the limiting columns 13 through the connecting rod two 10 and the connecting rod three 11.
