Abstract
Description
Technical Field
[0001] This application relates to the field of lasers, and more particularly to a clamping threaded pin for a laser. Background Technology
[0002] In existing technologies, lasers have a sophisticated structure, resulting in very small laser interface sizes. They typically employ an interference fit mounting method, where pins are hammered into the interface using a tool to lock the components together. However, once the pins are driven into the interface, disassembly is difficult, requiring them to be hammered out again. This results in a larger interface, making future maintenance impossible. Inconsistent hammering depths and the need for larger guide angles for the driven pins can also affect the clamping surface. Furthermore, hammering the pins can easily introduce debris. During insertion and removal of the laser from the interface, this debris can fall into the laser's internal cavity, potentially damaging the lenses. Utility Model Content

[0036] In existing technologies, lasers have a sophisticated structure, resulting in very small laser interface sizes. They typically employ an interference fit mounting method, where pins are hammered into the interface using a tool to lock the components together. However, once the pins are driven into the interface, disassembly is difficult, requiring them to be hammered out again. This results in a larger interface, making future maintenance impossible. Inconsistent hammering depths and the need for larger guide angles for the driven pins can also affect the clamping surface. Furthermore, hammering the pins can easily introduce debris. During insertion and removal of the laser from the interface, this debris can fall into the laser's internal cavity, potentially damaging the lenses.
[0037] In view of this, this application provides a clamping threaded pin for a laser, such as Figures 1-6 As shown, it includes:
[0038] The system includes a fixed base 20 and a laser fiber 30. The laser fiber 30 is fixedly installed in the fixed base 20 and is coaxially arranged with the fixed base 20. For example, the laser fiber 30 is inserted into the fixed base 20. A tapered surface is provided on the outer wall of the laser fiber 30. The tapered surface is initially positioned with the inner wall of the fixed base 20. However, the laser fiber 30 is not completely fixed in the fixed base 20 and can move axially relative to the fixed base 20.
[0039] Adjusting member 40, which is sleeved on the outer wall of the fixed base 20, and can rotate relative to the fixed base 20;
[0040] The threaded pin 10 is inserted into the adjusting member 40, the fixing seat 20 and the laser fiber 30 in sequence along the radial direction of the adjusting member 40, that is, in the direction towards the laser fiber 30. That is, the threaded pin 10 passes through the adjusting member 40 and the fixing seat 20 in sequence, and then presses against the outer wall of the laser fiber 30.
[0041] The threaded pin 10 includes a threaded section 11, a limiting section 12, and a clamping section 13. The threaded section 11 mates with the threaded hole 41 of the adjusting member 40, allowing control over the tightening depth of the threaded section 11 on the adjusting member 40, thus eliminating the need for a large guide angle for the threaded pin 10. The limiting section 12 is located between the threaded section 11 and the clamping section 13, and mates with the limiting hole 42 in the adjusting member 40, preventing the threaded pin 10 from being tightened to an excessive depth and damaging the outer wall of the laser fiber 30. The clamping section 13 extends through the sliding groove 21 of the fixed base 20 into the clamping groove 31 of the laser fiber 30. When the adjusting member 40 rotates to the preset position, it drives the threaded pin 10 to rotate relative to the fixed base 20. At the same time, the clamping section 13 also rotates to the preset position in the clamping groove 31 to clamp the inner wall of the clamping groove 31, thereby restricting the axial displacement of the laser fiber 30 in the fixed base 20 and realizing the fixation of the laser fiber 30 in the fixed base 20.
[0042] The working principle of this application is as follows: the threaded pin 10 is tightened onto the adjusting member 40 using a tool. After the laser fiber 30 is installed in the fixed base 20, an external force is applied to make the adjusting member 40 rotate around the fixed base 20. When the adjusting member 40 rotates to the preset position, the pressing section 13 of the threaded pin 10 will press against the inner wall of the pressing groove 31 on the laser fiber 30, thereby fixing the laser fiber 30 in the fixed base 20.
[0043] Therefore, this application provides a clamping threaded pin for a laser, in which a threaded pin 10 is threadedly fixed to an adjusting member 40. Rotation of the adjusting member 40 drives the threaded pin 10 to clamp the clamping groove 31 of the laser fiber 30, thereby fixing the laser fiber 30 in the fixing base 20. This application uses a threaded pin 10 to avoid generating debris during installation on the adjusting member 40, which could cause lens burn-out. Simultaneously, it does not enlarge the threaded hole, facilitating subsequent disassembly, replacement, and maintenance of various components.
[0044] To further improve the implementation of this application, the following structure is specifically adopted: a groove 21 is provided on the outer wall of the fixed base 20, the pressing section 13 passes through the groove 21, and the adjusting member 40 rotates relative to the groove 21 through the pressing section 13.
[0045] In the above scheme, the slide groove 21 and the clamping groove 31 are connected. When the adjusting member 40 rotates relative to the fixed seat 20, the clamping section 13 of the threaded pin 10 can slide along the slide groove 21, thereby guiding the adjusting member 40 to rotate in this direction. The end of the clamping section 13 can smoothly enter the clamping groove 31 and clamp with the inner wall of the clamping groove 31.
[0046] To further improve the implementation of this application, the following structure is specifically adopted: a guide surface 311 and a pressing surface 312 are provided on the lower wall of the pressing groove 31, the pressing surface 312 is connected to the guide surface 311, and the pressing section 13 slides along the guide surface 311 onto the pressing surface 312.
[0047] In the above scheme, the guide surface 311 is an inclined surface and the pressing surface 312 is a horizontal surface. With the setting of the guide surface 311, the pressing section 13 of the threaded pin 10 can first smoothly enter the pressing groove 31 through the inclined guide surface 311, and slowly slide along the guide surface 311 to the pressing surface 312, so that the pressing section 13 rises in the axial direction, thereby achieving the pressing of the pressing surface 312.
[0048] To further improve the implementation of this application, the following configuration structure is adopted: the angle between the guide surface 311 and the horizontal plane is 12° to 14°.
[0049] In the above scheme, the angle between the guide surface 311 and the horizontal plane is preferably 13.5°. This setting makes the connection between the guide surface 311 and the pressing surface 312 form a step, which can hold the threaded pin 10 and prevent it from loosening due to vibration.
[0050] To further improve the implementation of this application, the following structure is specifically adopted: the lower wall of the limiting hole 42 is lower than the pressing surface 312.
[0051] In the above scheme, the plane where the lower wall of the limiting hole 42 is located is set lower than the horizontal plane where the pressing surface 312 is located. This makes the axis of the threaded pin 10 installed on the adjusting member 40 lower than the axis when it is on the pressing surface 312. This causes the threaded pin 10 to be lifted when it is on the pressing surface 312. In order to maintain its original axis position, the threaded pin 10 will apply pressure downward to the pressing surface 312, thereby fixing the laser fiber 30 in the fixing seat 20.
[0052] To further improve the implementation of this application, the following structure is specifically adopted: the diameter of the limiting section 12 is smaller than the diameter of the threaded section 11, and the diameter of the clamping section 13 is smaller than the diameter of the limiting section 12. This arrangement facilitates the engagement of the threaded pin 10 with the corresponding component, and also facilitates assembly and disassembly.
[0053] To further improve the implementation of this application, the following structure is specifically adopted: the outer wall of the limiting segment 12 is lower than the bottom of the thread 111 of the thread segment 11, which avoids interference between the thread segment 11 and the outer wall of the limiting segment 12 when the thread segment 11 is engaged with the threaded hole 41 of the adjusting member 40, and allows the thread segment 11 and the threaded hole 41 to be fully connected and engaged.
[0054] To further improve the implementation of this application, the following structure is specifically adopted: the diameter of the clamping section 13 is 1mm to 3.5mm, so that the clamping section 13 can slide smoothly in the slide groove 21 and the clamping groove 31.
[0055] To further improve the implementation of this application, the following structure is specifically adopted: a positioning section 121 is formed at the connection between the limiting section 12 and the pressing section 13, which helps to position the threaded pin 10 in the adjusting member 40, and a rounded corner can be provided on the positioning section 121 to eliminate stress concentration of the threaded pin 10 on the adjusting member 40.
[0056] Furthermore, the end of the clamping section 13 is provided with a rounded corner to avoid wear between it and the clamping groove 31.
[0057] To further improve the implementation of this application, the following structural configuration is specifically adopted: the threaded pin 10 is made of stainless steel. Stainless steel has no hardness but has strength. After heat treatment, when the threaded pin 10 is tightened with tools, it is less likely to break or crack.
