Description

Technical Field

[0001] The utility model relates to the technical field of optical equipment, in particular to a clamping device and a laser. Background Art

[0002] In the related art, a concave mirror is a reflector with an inwardly concave surface, and the concave mirror can be used to focus light. During the use of the concave mirror, a clamping device is required to clamp and fix it. The existing clamping device can not only clamp the concave mirror on the one hand, but also adjust the pitch angle of the concave mirror on the other hand. Among them, after the clamping device adjusts the pitch angle of the concave mirror, when external force factors act on the clamping device, such as when the clamping device is vibrated, the clamping device may cause the adjusted pitch angle of the concave mirror to change under the action of vibration, which usually requires the staff to readjust the pitch angle of the concave mirror. Not only is the process cumbersome and time-consuming, but it also greatly increases their workload and is extremely inconvenient to use. Utility Model Content

After the clamping member clamps the lens, the operating member can be rotated to make the operating member protrude from the first threaded hole, thereby abutting against the first end of the base, which can make the third end of the clamping member rise relative to the fourth end. In this way, the clamping device can make the lens tilt down. Further, during the rotation process, the flexible nature of the connecting member will apply force to the clamping member and the base. Under the elastic force of the connecting member, the third end of the clamping member and the first end of the base are subjected to a force that approaches each other. Since the operating member is threadedly connected to the first threaded hole, at this time, the above-mentioned force forms a pre-tightening force between the thread and the screw thread, so that the relative position of the clamping member and the base can be effectively locked, thereby maintaining the tilt angle of the lens. In the prior art, after the lens tilts down, when the clamping device vibrates, the angle of the lens will change. In the present application, since the flexible structure can effectively lock the relative position of the clamping member and the base, the change of the angle of the lens is effectively avoided.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0035] Please refer to Figures 1 to 5In some embodiments, the clamping device 10 includes: a base 100, a clamping member 200, a connecting member 300, an operating member 400 and a fixing mechanism. The base 100 includes a first end 110 and a second end 120 that are arranged opposite to each other. The base 100 can be used to support the clamping member 200, and the base 100 can be used to fix to other platforms. The clamping member 200 is used to clamp the lens 11, and the lens 11 can be a concave mirror, a reflector or a convex mirror. The clamping member 200 includes a third end 210 and a fourth end 230 that are arranged opposite to each other, the third end 210 is on the same side as the first end 110, and the fourth end 230 is on the same side as the second end 120. The third end 210 is provided with a first threaded hole 220. The clamping member 200 and the base 100 are arranged at intervals in the height direction. The connecting member 300 is flexible, and the connecting member 300 can be made of copper, aluminum or magnesium. The connecting member 300 is connected to the second end 120 and the fourth end 230 to form a flexible structure, and the clamping member 200 can rotate relative to the base 100 with the connecting member 300 as the axis of rotation. Specifically, after the connecting member 300 connects the clamping member 200 and the base 100, the clamping member 200 and the base 100 can rotate relative to each other, and the third end 210 can rise. When the third end 210 rises, the lens 11 can be tilted down. When the lens 11 needs to be tilted up, the third end 210 can be lowered. The operating member 400 is threadedly connected to the first threaded hole 220. When the operating member 400 is rotated, the operating member 400 can protrude from the first threaded hole 220 and abut against the first end 110 of the base 100, so that the clamping member 200 can rotate relative to the base 100 with the connecting member 300 as the axis of rotation. The operating member 400 may be a bolt, the length of which is greater than the depth of the first threaded hole 220. After the bolt is threadedly connected to the hole wall of the first threaded hole 220, the bolt may protrude from the first threaded hole 220, thereby abutting against the base 100, so that the third end 210 of the clamping member 200 rises. In addition, after the third end 210 of the clamping member 200 rises to a certain height, the bolt may be rotated in the reverse direction, so that the third end 210 descends, which can adjust the pitch angle of the lens 11. In addition to being a bolt, the operating member 400 may be a rod-shaped object with threads arranged thereon, so as to achieve threaded connection with the hole wall of the first threaded hole 220.Specifically, the clamping member 200 can be used to clamp the lens 11. After the clamping member 200 clamps the lens 11, the operating member 400 can be rotated to make the operating member 400 protrude from the first threaded hole 220, thereby abutting against the first end 110 of the base 100. This can make the third end 210 of the clamping member 200 rise relative to the fourth end 230. In this way, the clamping device 10 can make the lens 11 tilt downward. Further, during the rotation process, the flexible nature of the connecting member 300 will apply force to the clamping member 200 and the base 100. Under the elastic force of the connecting member 300, the third end 210 of the clamping member 200 and the first end 110 of the base 100 are subjected to a force approaching each other. Since the operating member 400 is threadedly connected to the first threaded hole 220, at this time, the above-mentioned force forms a pre-tightening force between the thread and the screw tooth. In this way, the relative position of the clamping member 200 and the base 100 can be effectively locked, thereby maintaining the tilting angle of the lens 11. In the prior art, after the lens 11 is bent down, when the clamping device 10 vibrates, the angle of the lens 11 will change. In the present application, since the flexible structure can effectively lock the relative position of the clamping member 200 and the base 100, the change of the angle of the lens 11 is effectively avoided. Specifically, the clamping device 10 can be convenient for the staff to use.

[0036] In order to further prevent the angle of the lens 11 from changing, a fixing mechanism may be used to assist. In some embodiments, the fixing mechanism is connected to the base 100 and the clamping member 200, and the fixing mechanism is used to lock the relative position of the clamping member 200 and the base 100. Further, the fixing mechanism can lock the relative position of the clamping member 200 and the base 100. Under the dual effects of the fixing mechanism and the flexible structure, the angle of the lens 11 can be effectively prevented from changing.

[0037] Further, the specific structure of the fixing mechanism is introduced below, please refer to Figures 1 to 5In some embodiments, the fixing mechanism includes a locking member 500. The clamping member 200 is provided with a second threaded hole 240, and the base 100 is provided with a third threaded hole (not shown). The locking member 500 is threadedly connected to the hole wall of the second threaded hole 240 and the hole wall of the third threaded hole. Specifically, the main function of the operating member 400 is to fine-tune the pitch angle of the lens 11. By twisting the operating member 400, the operating member 400 can move up and down. The operating member 400 is screwed down, so that the clamping member 200 and the lens 11 are tilted downward as a whole; conversely, the operating member 400 is screwed up, so that the lens 11 is tilted upward as a whole. This fine-tuning method can accurately meet the user's personalized needs for the angle of the lens 11. Among them, the locking member 500 can be a bolt, or the locking member 500 can be a rod with a thread. After the pitch angle is adjusted by the operating member 400, the relative position of the clamping member 200 and the base 100 can be fixed by tightening the locking member 500 to ensure that the angle of the lens 11 will not change during use. That is, the fastening effect of the locking member 500 can effectively prevent the angle deviation caused by vibration or other external factors, and ensure the stability and use effect of the lens 11 in the clamping device 10. In addition, it should be noted that the method of fixing the clamping member 200 and the base 100 by the locking member 500 also has the characteristics of simple structure and low cost.

[0038] Further, in addition to the above-mentioned locking member 500, there are other ways to fix the clamping member 200 and the base 100. Specifically, in some embodiments, the fixing mechanism includes an elastic member. The elastic member is elastic, one end of the elastic member is connected to the clamping member 200, and the other end of the elastic member is connected to the base 100. The elastic member can be a spring. After the two ends of the spring are respectively connected to the clamping member 200 and the base 100, the elastic force of the spring can make the clamping member 200 and the base 100 close to each other. At the same time, under the joint action of one end of the operating member 400 abutting the base 100 and the other end connecting the clamping member 200, this can achieve the effect of locking the clamping member 200 and the base 100, and prevent the clamping member 200 from moving relative to the base 100. One end of the elastic member is connected to the clamping member 200, and the other end of the elastic member is connected to the base 100. Specifically, one end of the spring is connected to the first end 110, and the other end of the spring is connected to the third end 210, and the spring is in a stretched state.

[0039] Further, the following describes how the clamping member 200 is rotatably connected to the base 100. Figures 1 to 5In some embodiments, the connector 300 includes a copper sheet 310, a first fixing member and a second fixing member, one end of the copper sheet 310 is fixedly connected to the second end 120 by the first fixing member, and the other end of the copper sheet 310 is fixedly connected to the fourth end 230 by the second fixing member. That is, after fixing the two ends of the copper sheet 310, the clamping member 200 and the base 100 can rotate with the copper sheet 310 as the rotation axis. Specifically, the method of fixing the copper sheet 310 includes bolt connection, welding and riveting. The bolt connection method is first introduced below. The connector 300 includes a copper sheet 310, a first bolt 320 and a second bolt 330. The first fixing member can be the first bolt 320, and the second fixing member can be the second bolt 330. The copper sheet 310 is provided with a first through hole 311 and a second through hole 312, the side of the second end 120 is provided with a fourth threaded hole 130, and the side of the fourth end 230 is provided with a fifth threaded hole 250. The first bolt 320 passes through the first through hole 311 and is threadedly connected to the hole wall of the fourth threaded hole 130, and the second bolt 330 passes through the second through hole 312 and is threadedly connected to the hole wall of the fifth threaded hole 250. The copper sheet 310 can be fixed to the second end 120 and the fourth end 230 by the first bolt 320 and the second bolt 330. In this way, the copper sheet 310 can be deformed by lifting the first end 110, and the clamping member 200 can rotate relative to the base 100 with the connecting member 300 as the rotation axis, thereby realizing the mutual rotation of the clamping member 200 and the base 100. Specifically, after the two ends of the copper sheet 310 are connected to the clamp 200 and the base 100 respectively, the copper sheet 310, the clamp 200 and the base 100 will form a flexible structure, and the copper sheet 310 has good rigidity and softness. On the one hand, the copper sheet 310 can be bent, so that the clamp 200 rotates relative to the base 100. On the other hand, after the copper sheet 310 is bent for many times, the copper sheet 310 has good plasticity and ductility, which means that it can be bent repeatedly without breaking. Therefore, the use of the copper sheet 310 can also extend the service life of the clamping device 10. It should be noted that the flexibility of the copper sheet 310 can be restored to its original state after the external force is removed. Therefore, after the operating member 400 is rotated and the operating member 400 is retracted into the first threaded hole 220, the copper sheet 310 can also make the clamp 200 close to the base 100, so that the clamp 200 quickly returns to its initial state.

[0040] The following describes a method of fixing the copper sheet 310 by welding. That is, one end of the copper sheet 310 can be welded to the second end 120, and then the other end of the copper sheet 310 can be welded to the fourth end 230. In this way, the copper sheet 310 can be fixed to the second end 120 and the fourth end 230. In this way, the copper sheet 310 can be deformed by lifting the first end 110, and the clamping member 200 can rotate relative to the base 100 with the connecting member 300 as the rotation axis, thereby realizing the mutual rotation of the clamping member 200 and the base 100.

[0041] The following describes a method of fixing the copper sheet 310 by riveting. That is, one end of the copper sheet 310 can be fixed to the second end 120 by a rivet, and then the other end of the copper sheet 310 can be fixed to the fourth end 230 by a rivet. In this way, the copper sheet 310 can be fixed to the second end 120 and the fourth end 230, and in this way, the copper sheet 310 can be deformed by lifting the first end 110, and the clamping member 200 can rotate relative to the base 100 with the connecting member 300 as the rotation axis, thereby realizing the mutual rotation of the clamping member 200 and the base 100.

[0042] Further, the following describes how the clamping member 200 clamps the lens 11. Figures 1 to 5 In some embodiments, the clamping member 200 includes a main body 260 and two protrusions 270. The two protrusions 270 are respectively connected to the two ends of the main body 260, and the two protrusions 270 are protruding relative to the main body 260. The main body 260 and the two protrusions 270 jointly define a clamping groove 290 for clamping the lens 11. Specifically, after the main body 260 and the two protrusions 270 are connected, the clamping member 200 can be in a "["-shaped structure, so as to clamp the lens 11. In order to prevent the lens 11 from being damaged, a buffer layer can be provided on the groove wall of the clamping groove 290, and the material of the buffer layer can be a flexible material to protect the lens 11.

[0043] Further, the clamping groove 290 of the clamping member 200 mentioned above is used to clamp the lens 11, wherein after the lens 11 is placed in the clamping groove 290, the lens 11 may fall off from the clamping groove 290, thereby causing damage. In order to solve this problem, the lens 11 can be locked by a locking member 600, so in some embodiments, the clamping device 10 also includes a locking member 600. The protruding portion 270 is provided with a sixth threaded hole 280, and the locking member 600 is rotatably arranged in the sixth threaded hole 280, and the locking member 600 can protrude from the sixth threaded hole 280 and abut against the lens 11. Specifically, the locking member 600 can be a screw, or the locking member 600 can be provided with a thread, and the locking member 600 rotates in the sixth threaded hole 280, so that the locking member 600 protrudes from the sixth threaded hole 280 and abuts on the edge of the lens 11, thereby abutting the lens 11 and effectively preventing the lens 11 from falling off.

[0044] Further, in some embodiments, a plurality of locking members 600 are provided, a plurality of sixth threaded holes 280 are provided, and a plurality of sixth threaded holes 280 are arranged at intervals, and each locking member 600 is arranged in a sixth threaded hole 280. Specifically, under vibration or dynamic load conditions, a single locking member 600 may loosen. However, when a plurality of locking members 600 act simultaneously, even if one or several of the locking members 600 loosen, the other locking members 600 can still remain tightly connected, thereby reducing the risk of the overall connection loosening. Therefore, the lens 11 can be further locked by a plurality of locking members 600. In addition, even if one locking member 600 fails, the other locking members 600 can still remain connected, thereby reducing the risk of the lens 11 falling off.

[0045] Further, in some embodiments, there are multiple operating members 400, and there are multiple first threaded holes 220, and each operating member 400 is disposed in one first threaded hole 220. There may be two operating members 400, and the two operating members 400 may be located on both sides of the locking member 500, respectively. After the two operating members 400 protrude from the first threaded holes 220, the two operating members 400 can adjust the pitch angle of the lens 11 on the one hand, and on the other hand, the supporting effect of the two operating members 400 is relatively stable, which can avoid the situation where the clamping member 200 is tilted relative to the base 100. That is, if the clamping member 200 is tilted, the angle of the lens 11 will also change, which will lead to poor use effect.

[0046] Further, in some embodiments, the base 100 is provided with a fixing groove 140, and the fixing groove 140 is used for a fastener to pass through, so as to fix the base 100 on the optical platform. Specifically, the fixing groove 140 can be an oblong groove, and the fastener can be a screw. The optical platform is provided with a threaded hole, and the screw can pass through the fixing groove 140, so as to fix the base 100 on the optical platform. In addition to the fixing groove 140, the base 100 can also be provided with a fixing hole.

[0047] In some embodiments, the laser includes the clamping device 10 of any one of the above embodiments. The clamping member 200 can be used to clamp the lens 11. After the clamping member 200 clamps the lens 11, the operating member 400 can be rotated to make the operating member 400 protrude from the first threaded hole 220, thereby abutting against the first end 110 of the base 100. This can make the third end 210 of the clamping member 200 rise relative to the fourth end 230. In this way, the clamping device 10 can make the lens 11 tilt downward. Further, during the rotation process, the flexible nature of the connecting member 300 will apply force to the clamping member 200 and the base 100. Under the elastic force of the connecting member 300, the third end 210 of the clamping member 200 and the first end 110 of the base 100 are subjected to a force approaching each other. Since the operating member 400 is threadedly connected to the first threaded hole 220, at this time, the above-mentioned force forms a pre-tightening force between the thread and the screw tooth. In this way, the relative position of the clamping member 200 and the base 100 can be effectively locked, thereby maintaining the tilting angle of the lens 11. In the prior art, after the lens 11 is bent down, when the clamping device 10 vibrates, the angle of the lens 11 will change. In the present application, since the flexible structure can effectively lock the relative position of the clamping member 200 and the base 100, the change of the angle of the lens 11 is effectively avoided. Specifically, the clamping device 10 can be convenient for the staff to use. Furthermore, the laser with the clamping device 10 can be convenient for the staff to use.

[0048] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
