Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 2 In this embodiment, a high-precision fiber laser cutting machine includes a material collection box 1. The outer surface of the material collection box 1 is slidably connected to a mobile frame 2. Fixed plates 3 are fixed on the front and rear sides of the upper surface of the mobile frame 2. A cylinder 4 is fixed on the front of the front fixed plate 3.

The fiber laser cutting machine body 5 is fixed on the lower surface of the movable plate. Positioning mechanisms 6 are provided on the tops of the left and right sides of the material collection box 1 for positioning the workpiece to be cut. Pushing mechanisms 7 are provided on the front and rear ends of the left side of the material collection box 1 for pushing debris for easy cleaning by the staff.

The debris generated after the fiber laser cutting machine body 5 is cut can enter the inner cavity of the aggregate box 1 through the supporting mesh plate for collection.

[0024] It can be understood that the sliding movable frame 2 can adjust the position of the fiber laser cutting machine body 5, and then start the fiber laser cutting machine body 5, and then adjust the position of the fiber laser cutting machine body 5 through the cylinder 4 to perform cutting.

[0025] See also Figure 3 In order to improve the cutting accuracy of the workpiece to be cut, the positioning mechanism 6 in this embodiment includes a support plate 601 fixed to the top of the left and right sides of the aggregate box 1, and an electric push rod 602 is fixed to the inner cavity of the support plate 601.

The left and right ends of the connecting rod 605 are slidably connected with a sliding sleeve 606, and a clamping plate 607 is fixed between the opposite sides of the sliding sleeves 606 on the front and back sides. Start the two electric push rods 602, and the piston rods of the two electric push rods 602 extend, thereby pushing the two clamping plates 607 to move relative to each other. The movement of the two clamping plates 607 drives the two sliding sleeves 606 to move relative to each other on the outer surface of the connecting rod 605 until the two clamping plates 607 are in contact with the workpiece to be cut, so that the workpiece to be cut can be positioned.

[0026] A mounting bracket 608 is fixed in the middle of the upper surface of the clamping plate 607 . A moving rod 609 is slidably connected to the upper surface of the mounting bracket 608 , one end of which passes through and extends to the lower side of the mounting bracket 608 .

[0028] It can be understood that by unscrewing the threaded rod out of the inner cavity of the movable rod 609, the height of the pressure plate 610 can be adjusted up and down so that the lower surface of the pressure plate 610 fits with the upper surface of the workpiece to be cut, and then the threaded rod is screwed into the inner cavity of the corresponding through hole on the surface of the movable rod 609, and the upper, lower, left and right positions of the pressure plate 610 can be positioned.

[0029] Among them, the piston rod of the electric push rod 602 passes through the positioning plate 603 and extends to the opposite side of the two positioning plates 603 and is fixed to the clamping plate 607.

The set rubber plates can increase the friction between the pieces to be cut and improve the stability of positioning.

[0030] It should be noted that the workpieces to be cut placed on the aggregate box 1 can be positioned horizontally and vertically, so that the position of the workpieces to be cut is fixed, avoiding changes in the position of the workpieces to be cut due to touch by staff, thereby improving the cutting accuracy of the workpieces to be cut.

[0031] See also Figure 4 The outer surface of the screw 703 is threadedly connected to the screw sleeve 704, and the outer surface of the screw 703 is threadedly connected to the screw sleeve 704. The ...

[0032] Among them, the output shafts of the two driving motors 701 pass through the left side wall of the inner cavity of the aggregate box 1 and extend to the inner cavity of the installation box 702 and are fixed with two screws 703. The opposite sides of the two installation boxes 702 are provided with fixing holes to facilitate the screw sleeve 704 to drive the push plate 705 to move.

[0033] In this embodiment, guide holes that are compatible with the size of the installation box 702 are provided in the middle of the front and rear sides of the push plate 705. The size of the push plate 705 is compatible with the size of the inner cavity of the aggregate box 1. Limiting grooves are provided on the side opposite to the inner top wall and the inner bottom wall of the installation box 702. Limiting blocks are fixed on the upper and lower sides of the screw sleeve 704. The limiting blocks make horizontal linear motion in the inner cavity of the limiting groove. The set limiting blocks and limiting grooves can limit the movement of the screw sleeve 704, so that the screw sleeve 704 can only move in a linear direction.

[0034] It should be noted that the right end of the front side of the aggregate box 1 is hingedly connected to a cleaning door via a hinged seat.

[0035] The electrical components appearing in the text are all electrically connected to the main controller and the power supply, and the electrical components appearing in the text are all conventionally known devices. This application will not go into too much detail. The main controller can be a conventionally known device that controls a computer, etc. The control circuit of the main controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and this application is mainly used to protect mechanical devices, so this application will no longer explain the control method and circuit connection in detail.

[0036] The working principle of the above embodiment is:

[0037] (1) When cutting the workpiece to be cut, the workpiece to be cut is placed on the upper surface of the collecting box 1, and then the two electric push rods 602 are started. The piston rods of the two electric push rods 602 are extended, and then the two clamping plates 607 are pushed to move relative to each other. The movement of the two clamping plates 607 respectively drives the two sliding sleeves 606 to move relative to each other on the outer surface of the connecting rod 605 until the two clamping plates 607 are in contact with the workpiece to be cut. The workpiece to be cut can be positioned, and then the threaded rod is screwed out of the inner cavity of the moving rod 609, and the height of the pressure plate 610 can be adjusted up and down so that the lower surface of the pressure plate 610 is in contact with the upper surface of the workpiece to be cut. Then the threaded rod is screwed into the inner cavity of the through hole corresponding to the surface of the moving rod 609, and the upper, lower, left and right positions of the pressure plate 610 can be positioned. The sliding movable frame 2 can adjust the position of the fiber laser cutting machine body 5, and then the fiber laser cutting machine body 5 is started, and then the position of the fiber laser cutting machine body 5 is adjusted by the cylinder 4, and cutting can be carried out.

[0038] (2) The debris generated after the fiber laser cutting machine body 5 is cut can enter the inner cavity of the collection box 1 through the support mesh plate for collection. In order to facilitate the staff to clean, the driving motor 701 can be started when the staff is cleaning. The output shaft of the driving motor 701 rotates to drive the screw 703 to rotate. The rotation of the screw 703 causes the screw sleeve 704 threadedly connected to its surface to move horizontally. The movement of the screw sleeve 704 on the front and rear sides causes the push plate 705 to move, thereby pushing the material at the left end of the inner cavity of the collection box 1 to the right end, making it easier for the staff to clean from the cleaning door.
