Description

Technical Field

[0002] The laser positioning device of a cutting machine is an auxiliary device that uses laser technology to achieve precise positioning. Its core principle is to project a clear cursor on the working surface by emitting visible laser (such as red light), which helps the operator quickly determine the cutting path or reference point, thereby improving processing accuracy and efficiency.

[0003] The laser positioning device diffuses the laser beam into a line using an optical lens and utilizes a reflector to achieve simultaneous horizontal and vertical projection, forming crosshairs or straight lines. For example, in fabric cutting, the laser line can project clear crosshairs, helping the operator quickly align the cutting path.

[0004] The laser positioning device equipped on existing cutting machines has a prominent problem in actual use: due to the misalignment between the installation position of the laser positioning device and the emission point of the laser cutting head, the angle of the laser positioning device needs to be adjusted to ensure that the position illuminated by the laser positioning device is accurately aligned. However, when the height of the workpiece to be cut changes, the position illuminated by the laser positioning device cannot be accurately aligned, resulting in inaccurate positioning. Utility Model Content

Thus, the counterclockwise rotation of the first and second adjusting plates drives the two sets of adjusting lasers to rotate counterclockwise, thereby achieving the overlap of the laser irradiation points. This allows the lasers on both sides to correct the position of the cutting point, thereby improving the accuracy of the cutting position. Attached Figure Description

[0035] Working principle: First, the first fixed housing 131 is fitted onto the side surface of the laser cutting head and drives the first fixed hole 133 to be fitted onto the surface of the first stud 132. The device can be installed on the surface of the laser cutting head through the threaded connection between the first nut 134 and the first stud 132. Then, the second fixed housing 151 is fitted onto the surface of the laser 14 and drives the second fixed hole 153 to be fitted onto the surface of the second stud 152.

The counterclockwise rotation of the first rotating rod 2112 causes the first gear disc 2113 to rotate counterclockwise. When the first gear disc 2113 rotates counterclockwise, it drives the second gear disc 2116 to rotate clockwise. The counterclockwise rotation of the first gear disc 2113 causes the first sector gear 2123 to rotate clockwise. When the first sector gear 2123 rotates clockwise, it drives the first... When the adjusting plate 23 rotates clockwise, the second gear 2116 rotates clockwise, driving the second sector gear 2133 to rotate counterclockwise. When the second sector gear 2133 rotates counterclockwise, it drives the second adjusting plate 24 to rotate counterclockwise through the fourth rotating rod 2132. Thus, the counterclockwise rotation of the first adjusting plate 23 and the second adjusting plate 24 drives the two sets of adjusting lasers 14 to rotate counterclockwise, thereby achieving the overlap of the irradiation points of the adjusting lasers 14. In this way, the position of the cutting point can be corrected by the lasers 14 on both sides.
