Description

Technical Field

[0001] The utility model relates to the field of laser cutting machines, and particularly relates to an auxiliary positioning device for a laser cutting machine. Background Art

[0002] A laser cutting machine is an advanced device that uses a laser beam with a high power density to cut materials. When cutting a sheet, it is necessary to fix the sheet. In the prior art, a positioning device is used to fix the sheet during cutting, and after cutting, the positioning device needs to be loosened to pick up the sheet upwards. Such a working efficiency is relatively low, and time is wasted on the step of loosening the positioning device. Therefore, there is an urgent need for an auxiliary positioning device for a laser cutting machine that can quickly position and quickly release the positioning of the sheet, facilitating the operator to pick up the sheet and improving production efficiency.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0022] In the present utility model, unless otherwise clearly specified and defined, terms such as "arranged", "installed", "connected", "linked", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection or a detachable connection; it may be a mechanical connection; it may be a direct connection or an indirect connection through an intermediate medium.

[0023] An auxiliary positioning device for a laser cutting machine, characterized in that: it includes a support frame 1, a base 2 is arranged on the support frame, a lifting cylinder 3 is arranged on the base, a cutting platform 4 is arranged above the lifting cylinder, a laser cutting machine 7 is arranged above the cutting platform, sliding rails (not shown in the figure) are arranged on both sides of the cutting platform, two moving frames 5 are slidably connected in each sliding rail, locking devices 6 are rotatably connected to both ends of each moving frame, the two moving frames can slide according to the length of the plate to position the plate, after the plate is positioned, the locking devices lock the four corners of the plate to ensure the stability during plate cutting. Each locking device includes an L-shaped clamping plate 603, each L-shaped clamping plate is rotatably connected to the moving frame through a rotating shaft 606, an adjusting screw 601 is threadedly connected to the upper end of each L-shaped clamping plate, a pressing plate 602 is arranged at the lower end of each adjusting screw, the openings of the four L-shaped clamping plates all face the cutting platform, and the four L-shaped clamping plates are arranged in pairs at both ends of the moving frame. A rotating shaft is arranged at the bottom of the L-shaped clamping plate. When the plate needs to be cut, the L-shaped clamping plate is rotated above the plate, and the adjusting screw is rotated. The downward movement of the adjusting screw drives the pressing plate to move downward, thereby locking the plate to ensure that the four corners of the plate will not bend due to gravity and improving the accuracy during cutting.

[0024] A guide rod 604 is arranged on the outside of each L-shaped clamping plate close to the moving frame, and a guide groove 605 matching the guide rod is arranged at both ends of each moving frame.

The guide groove is arranged in an arc shape, and the trajectory of the guide groove is the same as the movement trajectory of the guide rod.

[0025] A buffer plate 8 is provided on each moving frame. The buffer plate is connected to the moving frame through a spring 9. When clamping both sides of the plate, it prevents the parts of both sides of the plate in contact with the moving frame from curling or deforming. A buffer plate is provided on the moving frame, and the buffer plate is connected to the moving frame through a spring. The spring can reduce the impact force of the two moving frames on the plate, and the spring can consume part of the energy during the impact process, thereby effectively reducing the impact force of the two moving frames and avoiding curling or deforming of the parts of the plate in contact with the moving frame. At one side of the locking device at both ends of each moving frame, there is a limit plate 11. The limit plate is arranged on the side of the moving frame away from the cutting platform. After cutting is completed, turn the adjusting screw upward, and the locking device can be rotated onto the limit plate, which is convenient for the operator to remove the plate from the cutting platform. A slider is fixedly connected to the lower end of each moving frame, and each moving frame is slidably connected to the slide rail through the slider. Cylinders are connected to both sides of each moving frame, and the cylinders push the moving frame to slide on the base.
