DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings, wherein several embodiments of the present application are given, but the present application can be realized in different forms, and is not limited to the embodiments described in the text, on the contrary, these embodiments are provided in order to make the disclosed content of the present application more thorough and comprehensive. EMBODIMENT

[0027] As Figures 1-6 shown, a positioning device of a numerical control die cutting plate laser cutting machine, including laser cutting machine 1, positioning stabilizer 2 and positioning clamp 3, laser cutting machine 1 is controlled by numerical control system responsible for the movement path and cutting parameters of laser head, and the laser cutting machine 1 also includes operation platform 11 and cutting workbench 12, cutting workbench 12 is located above the operation platform 11, the cutting workbench 12 is installed around the positioning clamp 3, the bottom surface of the positioning clamp 3 is installed on the operation platform 11, in addition, one side of the positioning clamp 3 is connected with the side surface of the cutting workbench 12, wherein the positioning clamp 3 includes automatic telescopic pump 31, bearing 32 is connected on the automatic telescopic pump 31, multi-section telescopic rod 33 is connected on the bearing 32, the multi-section telescopic rod 33 can rotate around the automatic telescopic pump 31 through the bearing, the multi-section telescopic rod 33 can move up and down above the die cutting plate 4 through the driving of the automatic telescopic pump 31, the positioning clamp 3 is evenly arranged along the cutting workbench 12, and the positioning mechanism is installed at one end of the multi-section telescopic rod 33 away from the bearing 33, for fixing the position of the die cutting plate 4 on the cutting workbench 12.

[0028] As Figure 1 , 2As shown in Figure 5, the fixing structure includes a positioning clamp 36, with a rubber pad 37 connected to the bottom of the positioning clamp 36. The rubber pad 37 increases friction, making the positioning clamp 36 more stable in fixing the die-cutting plate 4, and also protects the surface of the die-cutting plate 4 from damage. A sleeve 361 is provided above the positioning clamp 36, and a knob 34 is installed on the sleeve 361. The knob 34 includes a handle 341 and a screw 342. The handle 341 is located at one end of the screw 342. The end of the screw 342 away from the handle 341 passes through the threaded hole on the multi-section telescopic rod 33 and is threadedly connected to the sleeve 361 on the positioning clamp 36. This allows the positioning clamp 36 to be connected to the sleeve 361 on the multi-section telescopic rod 33. The telescopic rod 33 moves up and down to adjust the distance between itself and the die-cutting plate 4 in the general direction, driven by the automatic telescopic pump 31. It can also be rotated to easily adjust the angle via the bearing 32 at the other end of the multi-segment telescopic rod 33. Furthermore, the knob 34 can be used to further adjust the small distance between the positioning clamp 36 and the die-cutting plate 4, making the position of the die-cutting plate 4 more secure and accurate. At the same time, it can easily position and fix the die-cutting plate 4 with uneven thickness, improving the adaptability of the positioning fixture 3. In addition, a baffle 35 is provided on the lower surface of the multi-segment telescopic rod 33 on the side of the positioning clamp 36 near the automatic telescopic pump 31. The baffle 35 will abut against the edge of the die-cutting plate 4, making the positioning of the die-cutting plate 4 more accurate.

[0029] It should be noted that in this embodiment, the automatic telescopic pump 31 can be a gas-liquid booster pump. A high-pressure plunger controlled by a one-way valve continuously discharges liquid. When the pressure between the drive section and the output liquid section reaches equilibrium, the booster pump stops operating and no longer consumes air. When the output pressure decreases or the air drive pressure increases, the booster pump automatically starts operating until pressure equilibrium is reached again, at which point it automatically stops. The rotatable and telescopic design of the multi-segment telescopic rod 33 allows the positioning fixture 3 to cover a wider area on the cutting table 12, enabling it to adapt to die-cutting plates 4 of different sizes and shapes, thus expanding the adaptability of the positioning fixture 3.

[0030] like Figure 1 , 2 As shown in Figures 4 and 6, the positioning stabilizer 2 includes an air spring damper 22. A connecting bracket 21 is provided above the air spring damper 22. The positioning stabilizer 2 is connected to the operating table 11 through the connecting bracket 21. At the same time, a rubber foot pad 23 is provided at the bottom of the air spring damper 22, which can effectively absorb high-frequency vibrations. The positioning stabilizer 2 is installed at the bottom of the operating table 11. According to the size of the CNC die-cutting laser cutting machine 1, it is evenly distributed around its bottom. The center of gravity of the CNC die-cutting laser cutting machine 1 needs to be precisely calculated. Then, the positioning stabilizer 2 is placed at the center of gravity position at the bottom to balance the weight of the equipment and reduce vibration caused by the shift of the center of gravity.

[0031] It should be noted that in the present embodiment, the air spring shock absorber 22 is a more advanced damping device that uses compressed air to provide elastic support, and in the numerical control die cutting plate laser cutting machine 1, when the air spring shock absorber 22 is used, the air pressure can be accurately adjusted by the air pressure control system according to the actual operation of the equipment. For example, when the equipment starts and stops, the air pressure is appropriately increased to improve the stability of the equipment; during normal operation, the air pressure is fine-tuned according to the vibration situation to achieve the best damping effect.

[0032] The specific operation mode of the utility model is as follows:

[0033] First, the positioning stabilizer 2 is reasonably arranged at the bottom of the numerical control laser cutting machine 1 through calculation, then the die cutting plate 4 is placed on the cutting workbench 12 of the numerical control laser cutting machine 1, then the air spring shock absorber 22 in the positioning stabilizer 2 is appropriately increased in air pressure to improve the stability of the equipment, then the angle of the multi-section telescopic rod 33 is adjusted, the positioning clamp plate 36 is above the die cutting plate 4, then the automatic telescopic pump 31 is controlled to stretch and retract, thereby driving the multi-section telescopic rod 33 to move up and down, so that the rubber pad 37 can be close to the die cutting plate 4, finally the length of the multi-section telescopic rod 33 is adjusted, the baffle 35 is tightly attached to the side edge of the die cutting plate 4, then the knob 34 is twisted, the screw rod 341 is rotated and the positioning clamp plate 36 and the rubber pad 37 are moved downward at the same time, finally the rubber pad 37 is completely attached to the die cutting plate 4.

[0034] The basic principles and main features of the utility model and the advantages of the utility model are shown and described above. It should be understood by those skilled in the art that the utility model is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the utility model, and various changes and improvements can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed. The scope of protection of the utility model is defined by the appended claims and their equivalents.
