Description

Technical Field

[0001] The present application relates to the technical field of light beam switching head processing, and in particular to an anti-loosening device and light beam switching head processing equipment. Background Art

[0002] The QBH (Quick Beam Switching Head) window cap, also known as the QBH fiber output head protection cap or QBH protective lens cap, is a protective accessory designed for the QBH interface of fiber lasers. The QBH interface is a standardized fiber laser transmission interface, commonly used in industrial applications such as high-power laser cutting and welding, to achieve quick connection and disassembly between the laser and terminal optical components such as the cutting head and welding head.

[0003] The QBH window cap uses a fine thread with a pitch of 0.5. During the use of the product, vibration will occur, and the vibration will cause the QBH window cap to have the risk of loosening and falling off. Therefore, glue will be applied to the thread to prevent loosening. When the high-power QBH emits light, the front end of the window cap will be hot, and the high temperature will cause the glue to react, causing the window cap to burn out, which is not conducive to the use of the QBH window cap.

[0052] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present application provides an anti-loosening device 100. The anti-loosening device 100 includes a mounting assembly 110, a pressure assembly 120 and a fixing platform 130.

[0053] The pressure-applying assembly 120 is disposed on one side of the mounting assembly 110 , and the pressure-applying assembly 120 is fixedly connected to the mounting assembly 110 , and the fixed connection method is, for example, a bolt-fastened connection.

[0054] In addition, the fixing platform 130 is arranged on a side of the mounting component 110 close to the pressure component 120, the fixing platform 130 is located between the pressure component 120 and the mounting component 110, the fixing platform 130 is fixedly connected to the mounting component 110, and the fixing platform 130 is used to fix the window cap 200 of the beam switching head.

[0055] The pressure-applying assembly 120 includes a punching needle 1242 . The punching needle 1242 is disposed at one end of the pressure-applying assembly 120 close to the fixing platform 130 , and the punching needle 1242 is disposed corresponding to the fixing platform 130 .

[0056] In this embodiment, the punching needle 1242 applies pressure to the lens cover 201 of the window cap 200 on the fixed platform 130 to deform the lens cover 201, thereby deforming the screw thread between the lens cover 201 and the lens sleeve 202, thereby achieving an anti-loosening effect between the lens cover 201 and the lens sleeve 202, avoiding the use of glue, and increasing the service life of the window cap 200 of the beam switching head.

[0057] In the related art, the QBH window cap 200 is usually prevented from loosening by applying glue on the screw thread between the lens cover 201 and the lens sleeve 202. When the high-power QBH emits light, the front end of the window cap 200 will be hot, and the high temperature will cause the glue to react, thereby causing the window cap 200 to burn out, which is not conducive to the use of the QBH window cap 200.

[0058] In this embodiment, the anti-loosening device 100 includes a mounting assembly 110, a pressure assembly 120 and a fixed platform 130. In this embodiment, the window cap 200 of the beam switching head is fixed on the fixed platform 130, and the surface of the lens cover 201 of the window cap 200 is impacted by the punching needle 1242 in the pressure assembly 120, so that the lens cover 201 is deformed, and then the screw thread between the lens cover 201 and the lens cover 202 is deformed, thereby achieving an anti-loosening effect between the lens cover 201 and the lens cover 202. The anti-loosening device 100 of this embodiment avoids the use of glue to fasten the window cap 200, reduces the damage rate of the window cap 200 of the beam switching head, increases the service life of the window cap 200 of the beam switching head, and reduces the risk of laser failure.

The pressing part 124 includes the punching needle 1242 , that is, the second transmission part 123 drives the punching needle 1242 to approach or move away from the fixed platform 130 .

[0079] Alternatively, if Figure 8 As shown, the first transmission part 122 includes a first sleeve 1221 and a transmission wheel 1222 .

[0080] The first sleeve 1221 is disposed at an end of the connecting portion 121 away from the mounting rod 112 , and the first sleeve 1221 is connected to the connecting portion 121 , and the first sleeve 1221 has a first accommodating cavity.
