Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, and more specifically, to a jig for laser cutting. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting. During cutting, a jig is required to position the workpiece.

[0003] However, when cutting the workpiece, the traditional jig can only play a fixing role, resulting in the debris on the cutting path being blocked by the cutting edge of the raw material and not being easy to blow away directly. As the cutting continues, the debris is likely to be fused to the raw material, affecting the product quality. In addition, the direct method of blowing away the debris is likely to cause dust pollution to the surrounding cutting environment, which is not only difficult to clean, but also easily affects the accuracy of the bottom moving module. Therefore, a jig for laser cutting is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a jig for laser cutting to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a jig for laser cutting, comprising a dust collecting trough, a jig plate provided on the top of the dust collecting trough, a fixing frame installed on the top edge of the jig plate, the fixing frame being connected to the dust collecting trough by bolts to clamp and fix the jig plate, a first end tube being installed at the bottom of the dust collecting trough, a second end tube being installed on one side of the first end tube, and the installation positions of the first end tube and the second end tube being centrally symmetrical with respect to the center of the dust collecting trough.

[0006] Preferably, the dust collecting trough includes a bottom plate and a surround, and the surround is integrally formed with the bottom plate so that a notch is formed in the middle of the dust collecting trough.

[0007] Preferably, the jig plate is evenly provided with chip removal holes and positioning holes, and the diameter of the chip removal holes is larger than the diameter of the positioning holes.

[0008] Preferably, a bolting plate is installed in the middle of the bottom end of the dust collecting trough, and a plurality of screw holes are opened on the bolting plate.

[0009] Preferably, the first end tube and the second end tube are both connected to a corrugated air pipe, and the corrugated air pipe is connected to an air suction device.

[0010] The technical effects and advantages of this utility model are:

[0011] 1. The dust collecting trough is connected to the movable slide of the laser cutting equipment through the bolting plate at the bottom, and the first end tube and the second end tube are respectively connected to the suction equipment through the corrugated air pipe. After the material is placed on the jig plate and positioned correctly, the suction equipment is operated to generate negative pressure on the jig plate, thereby adsorbing and positioning the raw material. After the raw material is adsorbed and positioned, the laser cutting equipment cuts the raw material. During the cutting process, the debris generated generates negative pressure in the dust collecting trough under the operation of the suction equipment, so that the debris is directly sucked into the dust collecting trough from the jig plate, and then transported and discharged outward from the first end tube and the second end tube, realizing the automatic cleaning function, thereby avoiding the debris from polluting the surrounding environment, ensuring the cleanliness of the jig surface, and thus improving the quality of the product after cutting.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0018] As attached Figure 1-4 The laser cutting jig shown includes a dust collecting trough 1, a jig plate 2 is provided on the top of the dust collecting trough 1, a fixing frame 3 is installed on the top edge of the jig plate 2, and the fixing frame 3 is connected to the dust collecting trough 1 by bolts to clamp and fix the jig plate 2. A first end tube 4 is installed at the bottom of the dust collecting trough 1, and a second end tube 5 is installed on one side of the first end tube 4. The installation positions of the first end tube 4 and the second end tube 5 are centrally symmetrical with the center of the dust collecting trough 1.

[0019] During specific implementation, the bolting plate 6 at the bottom of the dust collecting trough 1 is connected to the movable slide of the laser cutting equipment, and the first end tube 4 and the second end tube 5 are respectively connected to the suction equipment through the corrugated air pipe. After the material is placed on the jig plate 2 and positioned correctly, the suction equipment is operated to generate negative pressure on the jig plate 2, thereby adsorbing and positioning the raw material. After the raw material is adsorbed and positioned, the laser cutting equipment cuts the raw material. During the cutting process, the debris generated generates negative pressure in the dust collecting trough 1 under the operation of the suction equipment, so that the debris is directly sucked into the dust collecting trough 1 from the jig plate 2, and then transported and discharged outward from the first end tube 4 and the second end tube 5, realizing the automatic cleaning function, thereby avoiding the debris from polluting the surrounding environment, ensuring the cleanliness of the jig surface, and thus improving the quality of the product after cutting.

[0020] The dust collecting trough 1 includes a bottom plate and a surrounding block, and the surrounding block and the bottom plate are integrally formed so that a notch is formed in the middle of the dust collecting trough 1.

[0021] During specific implementation, after the jig plate 2 is installed on the top of the slot, a cavity is formed between the dust collecting trough 1 and the jig plate 2, so that when inhaling, a negative pressure is formed in the cavity, so that the raw material can be adsorbed on the jig plate 2, and the debris falling after cutting can directly enter the cavity, and finally be discharged from the first end tube 4 and the second end tube 5.

[0022] The jig plate 2 is evenly provided with chip removal holes 7 and positioning holes 8 , and the diameter of the chip removal holes 7 is larger than that of the positioning holes 8 .

[0023] During specific implementation, negative pressure is formed in the cavity, so that the outside air flows into the cavity from the chip removal holes 7 and the positioning holes 8. When the material is placed on the jig plate 2 to block the flow of air, the material can be directly adsorbed and fixed on the jig plate 2. During the cutting process, the obstruction of the chip removal holes 7 on the cutting path also disappears, so that the debris dropped by the cutting is brought into the cavity along the direction of the air flow, thereby realizing automatic cleaning of the debris.

[0024] A bolting plate 6 is installed at the middle of the bottom end of the dust collecting trough 1, and a plurality of screw holes are opened on the bolting plate 6.

[0025] In specific implementation, the screw holes provided on the bolting plate 6 are aligned with the holes provided on the movable slide of the laser cutting equipment, and the bolting plate 6 can be fixed by installing nuts, so that the entire fixture is fixed on the movable slide.

[0026] The first end tube 4 and the second end tube 5 are both connected to a corrugated air pipe, and the corrugated air pipe is connected to an air suction device.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
