[0021] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0022] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0024] Reference Figure 1-5 A laser hole reaming device comprises a processing table 1, an L-shaped bracket 2 and a workpiece body 3. An L-shaped bracket 2 is arranged on one side of the top surface of the processing table 1. An angle guide motor 14 is connected to the end of the L-shaped bracket 2. A multilateral connecting rod 10 is connected to the surface of the multilateral connecting rod 10. A second hole reaming adjustment component 6 is connected to the end of the second hole reaming adjustment component 6. A motor connecting seat 9 is arranged on the bottom surface of the motor connecting seat 9. A guide seat 7 is connected to the output shaft of the laser guide motor 8. A first hole reaming adjustment component 5 is arranged on the side of the guide seat 7. A laser laser 4 is connected to the end of the first hole reaming adjustment component 5. When the whole device is actually used, the workpiece surface is reamed by the cooperation of various devices on the surface of the processing table 1. During the actual use, the window opening on the surface of the workpiece body 3 is overlapped with the laser point emitted by the laser laser 4, and the radius of the hole expansion circle is confirmed according to the size of the hole expansion. The radius is adjusted by the first hole expansion adjustment component 5 for adaptation, and then the laser guide motor 8 drives the laser laser 4 to rotate a circle to the window opening position through the first hole expansion adjustment component 5, and then the angle guide motor 14 sets the rotation unit angle according to the overlapping hole rate. After the laser guide motor 8 completes a circular path, the angle guide motor 14 randomly rotates a unit angle, and then the laser guide motor 8 completes a circular path again, until the angle of the angle guide motor 14 rotates one circle to complete the hole expansion processing on the surface of the workpiece body 3.

[0025] To facilitate the adjustment of the first hole expansion adjustment component 5, the first hole expansion adjustment component 5 is provided with an electric telescopic rod 502 and a connecting screw seat 501. A connecting screw 503 is provided at one end of the electric telescopic rod 502. A connecting screw seat 501 is provided at the end of the connecting screw 503. The bottom surface of the connecting screw seat 501 is bolted to the top surface of the laser laser 4. A positioning rod 504 is provided at the other end of the connecting screw 503. A guide seat 7 is connected to the end of the positioning rod 504. The guide seat 7 is connected to the output shaft of the laser guide motor 8. The first hole expansion adjustment component 5 is positioned by connecting the screw seat 501 and the guide seat 7. The two ends of the electric telescopic rod 502 are connected to the laser laser 4 and the laser guide motor 8 respectively through the connecting screw 503 and the positioning rod 504. The electric telescopic rod 502 automatically extends its length to adapt to the radius of the hole expansion circle to meet the hole expansion requirements of the window opening position.

[0026] In order to increase the stability of the connection of the first hole expansion adjustment component 5, connecting screw grooves 505 are provided on both sides of the surface of the connecting screw seat 501, and the connecting screw grooves 505 are threadedly connected to the surface of the connecting screw 503. The surface of the positioning rod 504 penetrates the surface of the guide seat 7, and the end of the positioning rod 504 is bolted to the surface of the guide seat 7, so that the two ends of the electric telescopic rod 502 remain connected to prevent falling off.

[0027] In order to maintain the connection of the angle guide motor 14, a multilateral connecting rod 10 is provided at the end of the second hole expansion adjustment component 6, and a positioning screw 12 is provided at the top and bottom of the multilateral connecting rod 10. The top of the multilateral connecting rod 10 is threadedly connected to the output shaft of the angle guide motor 14 through the positioning screw 12. A positioning groove 11 is provided at the end of the second hole expansion adjustment component 6, and the multilateral connecting rod 10 and the surface of the positioning groove 11 are penetrated. A positioning nut 13 is provided on the surface of the positioning screw 12, and the positioning nut 13 is abutted against the surface of the second expansion adjustment component, so that the angle guide motor 14 is connected to the second hole expansion adjustment component 6 through the multilateral connecting rod 10. When the angle guide motor 14 rotates, the entire laser guide motor 8, the first hole expansion adjustment component 5 and the laser laser 4 can be driven to rotate at an angle through the multilateral connecting rod 10 and the second hole expansion adjustment component 6, so as to facilitate the realization of the hole expansion path.

[0028] Other limiting structures of the entire device are that the vertical center line of the angle guide motor 14, the vertical center line of the multilateral connecting rod 10 and the vertical center line of the laser 4 all coincide with each other, maintaining the stability of the path and not deviating. The installation positions of the first hole expansion adjustment component 5 and the second hole expansion adjustment component 6 are parallel to each other, and the bottom surface of the workpiece body 3 is against the top surface of the processing table 1. Specific embodiment 2:

[0030] Reference Figure 1-5In order to increase the adaptability of the entire device when adjusting the radius, the first hole reaming adjustment component 5 and the second hole reaming adjustment component 6 are set to have the same structure, and the electric telescopic rods 502 of the first hole reaming adjustment component 5 and the second hole reaming adjustment component 6 are synchronously controlled. The second hole reaming adjustment component 6 extends along with the extension of the first hole reaming adjustment component 5. When the first hole reaming adjustment component 5 and the second hole reaming adjustment component 6 are extended and adjusted, one end is generally extended. It is inconvenient to keep the end close to the laser laser 4 in position, and the position of the laser guide motor 8 is adjusted by extension. Specific embodiment three:

[0032] Reference Figure 1-5 In actual use, the first hole expansion adjustment component 5 and the second hole expansion adjustment component 6 can be replaced by other telescopic structures, such as cylinders, electric gas rods and other structures for telescopic control. When controlling the size, the size is generally input and controlled by the PLC panel. The specific circuit structure is set according to actual use requirements and combined with existing circuit control technology.

[0033] In summary:

[0034] The angle guide motor 14 and the laser guide motor 8 are connected with the first hole expansion adjustment component 5 and the second hole expansion adjustment component 6 to perform laser hole expansion on the surface of the workpiece body 3. The hole expansion is performed by setting the hole expansion radius at the fixed point position and then drawing a circle around the circumference to cut and expand the hole. Holes are drilled around the window position by laser drilling. The laser overlap rate is 30%. The angle is synchronously adjusted and adapted during laser hole expansion. Compared with the direct cutting method, the hole shape produced by this method is good, which can effectively avoid the problem of residual glue at the bottom of the hole, solve the potential risks of laser hole expansion drilling, and reduce costs.
