[0001] The utility model relates to the technical field of laser cutting equipment, and in particular to a laser head mounting mechanism for an optical fiber laser cutting machine. Background Art

[0002] After the optical lens is formed, there are flashes around it, which need to be removed during further processing. In order to ensure that no debris and flying dust are generated during the cutting process and to ensure the flatness of the cut surface after cutting, optical lenses are currently mostly cut with fiber laser cutting machines.

[0003] Reference Figure 1 The laser head installation mechanism of the existing fiber laser cutting machine includes a crossbeam 1, a drive seat 2, a laser head 3 and a cover body 4. The cover body 4 is installed on the crossbeam 1 through a connecting bolt 41. The drive seat 2 is slidably connected to the crossbeam 1 and a mounting sleeve 21 is provided on the drive seat 2. A positioning column 31 that can be inserted into the mounting sleeve 21 is provided on the laser head 3. A fastening bolt 211 for fixing the position of the positioning column 31 is provided on the mounting sleeve 21. After the installation is completed, the relative position between the laser head 3 and the drive seat 2 is fixed. When the drive seat 2 moves under the drive of the servo drive system or the hydraulic drive system, it can drive the laser head 3 to move.

[0004] When the laser head 3 needs to be replaced or repaired, the connecting bolts 41 on the cover body 4 need to be loosened and the cover body 4 needs to be removed from the crossbeam 1, and then the fastening bolts 211 on the mounting sleeve 21 need to be loosened, and then the positioning column 31 on the laser head 3 needs to be removed from the mounting sleeve 21 to release the positioning function between the laser head 3 and the driving seat 2, and finally the laser head 3 needs to be removed and repaired or replaced. The steps of the loading and unloading process of the laser head 3 are complicated, and the replacement efficiency of the laser head 3 is reduced. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1

[0026] The following is further described in conjunction with specific embodiments. Figure 2-Figure 6 As shown, the utility model is a laser head 3 mounting mechanism for a fiber laser cutting machine, comprising a crossbeam 1, a drive seat 2, a laser head 3 and a cover 4, the cover 4 is detachably mounted on the crossbeam 1 by connecting bolts 41, the drive seat 2 is slidably connected to the crossbeam 1, a positioning column 31 is arranged on the laser head 3, one side of the drive seat 2 is arranged with a mounting sleeve 21 for inserting the positioning column 31, and a positioning member 5 is arranged in the drive seat 2 and on both sides of the mounting sleeve 21, a through hole is provided in the mounting sleeve 21, and a positioning groove 311 is provided in the positioning column 31, and the positioning member 5 can be inserted into the positioning groove 311 through the hole, so as to fix the relative position of the laser head 3 and the drive seat 2, so that the drive seat 2 can drive the laser head 3 to move synchronously when it moves under the action of the driving source. A moving member 6 for driving the positioning member 5 to move out of the positioning groove 311 is arranged in the drive seat 2, and the moving member 6 passes through the drive seat 2 and extends to the lower part of the crossbeam 1. When the laser head 3 needs to be replaced or repaired, there is no need to open the cover body 4 for operation. It is only necessary to move the positioning member 5 out of the positioning groove 311 through the moving member 6, so that the position fixation between the laser head 3 and the drive seat 2 can be easily released, thereby facilitating the removal of the laser head 3 and improving the replacement efficiency of the laser head 3.

[0027] Reference Figure 3 , Figure 4 As shown, the positioning member 5 includes a positioning rod 51 and a positioning block 52. A sliding cavity 22 is provided in the driving seat 2. The positioning rod 51 is slidably connected in the sliding cavity 22 and one end of the positioning rod 51 extends outside the sliding cavity 22. The positioning block 52 is welded to one end of the positioning rod 51 outside the sliding cavity 22. The two sliding cavities 22 are provided with mounting grooves 23 on the sides close to each other. A tension spring 53 is provided in the mounting groove 23. The positioning rod 51 is fixedly connected to one end of the tension spring 53 facing outside the mounting groove 23. When not subject to external force from the moving member 6, the positioning rod 51 drives the positioning block 52 to move toward the direction close to the mounting sleeve 21 under the elastic force of the tension spring 53 and inserts into the positioning groove 311 of the positioning column 31, so as to fix the relative position between the positioning column 31 and the mounting sleeve 21.

[0028] Reference Figure 4 , Figure 5As shown, the moving member 6 includes a moving block 61 and a moving rod 62. A driving cavity 24 is provided in the driving seat 2 and before the two sliding cavities 22. The moving block 61 is slidably connected in the driving cavity 24. The moving rod 62 is fixedly arranged at the bottom of the moving block 61. A sliding groove 25 is provided on the driving seat 2 for the moving rod 62 to slide. A driven rod 54 is provided on the positioning rod 51. The driven rod 54 passes through the installation groove 23 and extends into the driving cavity 24. The moving block 61 is formed by a conical portion 611 and a rectangular portion 612. When the moving rod 62 drives the moving block 61 to move, the conical portion 611 can press the driven rod 54 when moving in the driving cavity 24 and drive the driven rod 54 to move out of the driving cavity 24, so that the positioning rod 51 drives the positioning block 52 to move out of the positioning groove 311. When the driven rod 54 drives the rectangular portion 612 to abut against the driven rod 54, the position of the driven rod 54 can be maintained, so that the positioning block 52 is completely moved out of the positioning groove 311, so that the staff can remove the laser head 3 from the beam 1 conveniently.

[0029] Reference Figure 4 , Figure 6 As shown, an arcuate surface 541 is provided at one end of the driven rod 54 facing the driving chamber 24, so that the driven rod 54 can move more smoothly when pressed by the moving block 61. When the moving block 61 moves to the end of the driving chamber 24 in the direction close to the mounting sleeve 21, the conical portion 611 separates from the driven rod 54, and the rectangular portion 612 abuts against the driven rod 54 to maintain the position of the driven rod 54, and the driven rod 54 is pressed against the rectangular portion 612 under the action of the tension spring 53, thereby improving the stability of the moving block 61.

[0030] Reference Figure 5 , Figure 6 As shown, a fixing member 7 for fixing the position of the moving rod 62 is provided at the bottom of the driving seat 2. When the moving block 61 moves to the end of the driving cavity 24 in a direction away from the mounting sleeve 21, the fixing member 7 can fix the position of the moving rod 62, thereby ensuring the stability of the moving rod 62 and preventing the moving rod 62 from shaking on the driving seat 2 and affecting the stability during the movement of the driving seat 2. The fixing member 7 includes a fixing plate 71 and a fixing bolt 72. The fixing plate 71 is welded to the driving seat 2. The fixing bolt 72 is penetrated through the fixing plate 71. The moving rod 62 is provided with a threaded hole for inserting the fixing bolt 72. The fixing bolt 72 is screwed into the moving rod 62 to fix the position of the moving rod 62 and prevent the moving rod 62 from moving relative to the driving seat 2.
