The lead screw 4 is rotatably arranged on the slide through a bearing. The fixing fixture 2 composed of the lead screw 4 and the two pressure blocks 5 can clamp the laser 1 by adjusting the distance between the two pressure blocks 5.

[0026] Embodiment 4, based on embodiment 3, a laser LENS repair fixture, such as Figure 1 and Figure 2 As shown, a temperature sensor 3 is also provided at the bottom of the fixing fixture 2, and the temperature sensor 3 is connected to an external temperature controller 17, and the external temperature controller 17 is connected to the heating plate 6. The external temperature controller 17 is provided to facilitate the control of the heating temperature of the heating plate 6, and the temperature sensor 3 is provided to measure the heat generated by the heating plate 6. The temperature sensor 3, the heating plate 6 and the external temperature controller 17 form a controllable heat generation circuit. The heating plate 6 is preferably an electric heating plate, because the electric heating plate is an electric heating device in which a resistance heating wire is wound on a mica board (mica sheet), and has the advantages of high temperature resistance and good insulation performance.

[0027] Embodiment 5, based on embodiment 4, a laser LENS repair fixture, such as Figure 1 and Figure 2 As shown, the workbench is also provided with a push claw 10, which is located above the fixing fixture 2. The push claw 10 is provided so that after the glue softens, the LENS 18 is separated from the laser 1 housing under the reverse force of the push claw 10.

[0028] Embodiment 6, based on embodiment 5, a laser LENS repair fixture, such as Figure 1 and Figure 2As shown, the workbench includes a slide support plate 12, and a height-adjustable limit mechanism 11 is provided on the top of the slide support plate 12, and the limit mechanism 11 is connected to the push claw 10. The setting of the limit mechanism 11 is to facilitate the adjustment of the height of the push claw 10 on the slide support plate 12, so that the front end of the push claw 10 is close to the LENS 18 to be removed, so that the push claw 10 can apply a reaction force to the LENS 18. Because the push claw 10 has to withstand a large force, it needs to have good strength, toughness and hardness, so the material is preferably Cr12MoV, and vacuum heat treatment.

[0029] Embodiment 7, based on embodiment 6, a laser LENS repair fixture, such as Figure 1 , Figure 2 and Figure 3 As shown, a limit plate 15 is provided on the slide, and a limit screw 16 is provided on the limit plate 15. The limit plate 15 and the limit screw 16 are provided because the space inside the laser 1 is compact and the spacing between adjacent LENS 18 on the laser 1 is small, in order to prevent the push claw 10 from over-impacting and injuring other devices. The limit plate 15 and the limit screw 16 are used to limit the displacement of the push claw 10 during impact. The limit screw 16 is threadedly connected to the limit plate 15, and the displacement of the X-axis slide 7 during impact of the push claw 10 can be adjusted by adjusting the length of the limit screw 16 extending out of the limit plate 15, so as to avoid excessive displacement of the X-axis slide 7, over-impacting of the push claw 10 and injuring other devices.

[0030] Embodiment 8, based on any one of embodiments 1 to 7, a laser LENS repair fixture, such as Figure 1 and Figure 2 As shown, the slide includes an X-axis slide 7 and a Y-axis slide 9, the bottom of the slide support plate 12 is slidably connected to the Y-axis slide 9, the Y-axis slide 9 is connected to the bottom plate 14, the bottom plate 14 is slidably connected to the X-axis slide 7, the pressure block 5 is located on the top of the X-axis slide 7, the limit plate 15 is arranged on the slide support plate 12, and the limit screw 16 is arranged on the sliding path of the X-axis slide 7. The X-axis slide 7 can slide along the slide support plate 12 in the X-axis, and the Y-axis slide 9 can slide along the slide support plate 12 in the Y-axis. The setting of the X-axis slide 7 and the Y-axis slide 9 is to further adjust the position of the laser 1 so as to facilitate adjusting the LENS 18 to be removed from the laser 1 to a position close to the push claw 10.

[0031] The sliding connection between the Y-axis slide 9 and the slide support plate 12 is that a slide groove is provided on the Y-axis slide 9, a slider is provided on the slide support plate 12, and the slider and the slide groove are slidably matched. The sliding connection between the X-axis slide 7 and the slide support plate 12 is that a slide groove is provided on the X-axis slide 7, a slider is provided on the slide support plate 12, and the slider and the slide groove are slidably matched.

The X-axis slide 7 is driven to move by rotating the slide knob 8. The X-axis slide 7 of the present application is also required to generate a thrust to push off the LENS 18 softened by heat, because the fixture needs to be heated during use. In order to prevent the metal from expanding and jamming the X-axis slide 7, the X-axis slide 7 adopts a gear rack structure, with a large gap between the gear racks, a large torque bearing capacity, good wear resistance, and no jamming of the X-axis slide 7. In addition, the slide knob 8 is an extended type, that is, the length of the slide knob 8 extending along the axial direction of the gear from the X-axis slide 7 is extended, and the extended section is flattened. Extending the length of the slide knob 8 is equivalent to lengthening the force arm, reducing the force required to be applied, which is more labor-saving. At the same time, when a larger thrust is required, a wrench can be used to clamp the flattened extended section to apply force.

[0033] Embodiment 10, based on embodiment 9, a laser LENS repair fixture, such as Figure 1 , Figure 2 and Figure 3 As shown, the bottom plate 14 is rotatably connected with an R rotary slide 13, and the X-axis slide 7 is connected to the top of the R rotary slide 13. The R rotary slide 13 is provided to further adjust the position and angle of the LENS 18 on the laser 1, so as to facilitate adjusting the LENS 18 to be removed from the laser 1 to a position close to the push claw 10 and to an angle that is convenient for removing the LENS 18.

The limit screw 16 on the limit plate 15 is also on the moving path of the X-axis slide 7. The displacement of the X-axis slide 7 when the push claw 10 impacts is adjusted by adjusting the extension length of the end of the limit screw 16 extending out of the limit plate 15 toward the X-axis slide 7, so that the displacement of the X-axis slide 7 is less than the spacing between adjacent LENS 18 on the laser 1, thereby avoiding excessive displacement of the X-axis slide 7, over-impact injury of the push claw 10 and other devices. The R rotating slide 13 is rotatably connected to the bottom plate 14, which means that a rotating shaft is provided on the bottom plate 14, and a through hole is provided on the R rotating slide 13, which is matched with the rotating shaft, or a bearing is fixedly connected in the through hole, and the bearing is matched with the rotating shaft, so that the R rotating slide 13 is rotatably set on the bottom plate 14.
