[0032] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-5 This utility model provides a technical solution: a metal composite plate processing fixture with precise positioning, including a housing 1, a first motor 2 is provided on one side of the housing 1, a fixing component 7 is provided inside the housing 1, and two symmetrical first through holes 5 and second through holes 6 are respectively opened on the top of the housing 1.

[0034] The fixed assembly 7 includes a worm gear 703, with a first lead screw 702 fixedly connected to both ends of the worm gear 703. The first lead screw 702 is rotatably connected to the housing 1 through a first bearing. Both ends of the first lead screw 702 are threadedly connected to a first threaded seat 701. A worm wheel 704 meshes below the worm gear 703. Both sides of the worm wheel 704 are fixedly connected to a second lead screw 705. Both ends of the second lead screw 705 are threadedly connected to a second threaded seat 706. The second lead screw 705 is rotatably connected to the housing 1 through a second bearing. One end of the first lead screw 702 extends to the outside of the housing 1 and is fixedly connected to one end of the output shaft of the first motor 2. One side of the first motor 2 is fixedly connected to the outside of the housing 1 through a first fixing plate.

[0035] The specific implementation method is as follows: After the metal composite plate is placed on the top of the machine box 1, the first motor 2 drives the first lead screw 702 and the worm gear 703 to rotate synchronously, causing the worm wheel 704 to drive the second lead screw 705 to rotate. The first thread seat 701 and the second thread seat 706 push the first fixing block 707 and the second fixing block 709 closer to the metal composite plate. Then, by operating the first hand crank 3 and the second hand crank 4, the third lead screw 708 and the fourth lead screw 710 drive the first fixing block 707 and the second fixing block 709 to fix the metal composite plate, ensuring stability. This design allows the position of the first fixing block 707 and the second fixing block 709 to be adjusted independently, thereby flexibly adapting to metal composite plates of different sizes, effectively improving the fixing and clamping efficiency of the same batch of metal composite plates, and further improving the processing speed.

[0036] Each of the two first threaded seats 701 has a first fixing block 707 on one side facing each other. A first slide rod 711 is located directly above the first lead screw 702. A third lead screw 708 is located at both ends of the first slide rod 711. The third lead screw 708 is rotatably connected to the first threaded seat 701 through a third bearing. The first fixing block 707 is threadedly connected to the third lead screw 708 through a first threaded sleeve. One end of the first slide rod 711 extends to the outside of the third lead screw 708 and is fixedly connected to a first drive shaft. One end of the first drive shaft extends to the outside of the housing 1 and is fixedly connected to a first hand crank 3. A first slide rod 711 is located directly below the first slide rod 711. There is a second slide rod 712, and a fourth lead screw 710 is provided at both ends of the second slide rod 712. The fourth lead screw 710 is rotatably connected to the second threaded seat 706 through a fourth bearing. A second fixing block 709 is provided on the opposite side of each of the two second threaded seats 706. The second fixing block 709 is threadedly connected to the fourth lead screw 710 through a second threaded sleeve. One end of the second slide rod 712 extends to the outside of the fourth lead screw 710 and is fixedly connected to a second drive shaft. One end of the second drive shaft extends to the outside of the housing 1 and is fixedly connected to a second hand crank 4. The first lead screw 702, the second lead screw 705, the third lead screw 708, and... The threads on both sides of the fourth lead screw 710 are in opposite directions. The outer peripheries of the first slide rod 711 and the second slide rod 712 are rotatably connected to the sixth bearing via sleeves and fixed seats. The top of the fixed seats is fixedly connected to the top side inside the housing 1. The third lead screw 708 and the fourth lead screw 710 both have cross-shaped grooves inside. The cross-sections of the first slide rod 711 and the second slide rod 712 are both cross-shaped, and they are slidably connected within the cross-shaped grooves. The first drive shaft and the second drive shaft are rotatably connected inside the housing 1 via the seventh bearing. The first fixed block 707 and the second fixed block 709 are horizontally... The cross-section is T-shaped. The first fixing block 707 is slidably connected in the first through hole 5, and the second fixing block 709 is slidably connected in the second through hole 6. The inside of the chassis 1 is provided with two first sliding grooves and two second sliding grooves. The first sliding groove is located above the second sliding groove. The first through hole 5 is connected to the first sliding groove, and the second through hole 6 is connected to the second sliding groove. The first protective plate 8 is fixedly connected to both sides of the first fixing block 707, and the two first protective plates 8 are slidably connected in the first sliding groove. The second protective plate 9 is fixedly connected to both sides of the second fixing block 709, and the two second protective plates 9 are slidably connected in the second sliding groove.

[0037] The specific implementation method is as follows: During the process of fixing the metal composite plate, the first fixing block 707 and the second fixing block 709 drive the first protective plate 8 and the second protective plate 9 to slide in the first slide groove and the second slide groove. During the sliding process, the first through hole 5 and the second through hole 6 are covered to prevent waste chips and other impurities generated during the processing from entering the inside of the machine box 1, thereby ensuring the cleanliness of the internal environment of the machine box 1 and the stability of the device operation.

[0038] Working principle: During use, the metal composite plate is placed on top of the chassis 1. The first motor 2 is started, which drives the first lead screw 702 and worm gear 703 to rotate. The worm gear 703 drives the second lead screw 705 to rotate through the worm wheel 704. The first lead screw 702 and the second lead screw 705 drive the first fixing block 707 and the second fixing block 709 to move closer to the metal composite plate through the first thread seat 701 and the second thread seat 706, respectively. Then, the first hand crank 3 is started. The first hand crank 3 drives the two first fixing blocks 707 to move along the third lead screw 708 through the third lead screw 708 and the first slide bar 711. The second hand crank 4 is started. The second hand crank 4 drives the two second fixing blocks 709 to slide along the fourth lead screw 710 through the fourth lead screw 710 and the second slide bar 712 to fix the metal composite plate. After processing is completed, the first motor 2 drives the first lead screw 702 to reverse and cancel the fixation of the metal composite plate.

[0039] During the fixing process, the first fixing block 707 and the second fixing block 709 drive the first protective plate 8 and the second protective plate 9 to slide in the first slide groove and the second slide groove, covering the first through hole 5 and the second through hole 6, preventing waste chips and other impurities generated during the processing from falling into the machine box 1.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
