Description

Technical Field

[0001] The utility model belongs to the technical field of laser installation, and in particular relates to a clamping device which is easy to adjust. Background Art

[0002] Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working materials. Due to differences in material structure, the specific process of producing lasers in different types is relatively special. Semiconductor diode lasers are the most practical and important type of lasers. They are small in size, long in life, and can be pumped by a simple method of injecting current. Their operating voltage and current are compatible with integrated circuits, so they can be monolithically integrated with them. Semiconductor lasers need to maintain the stability of laser emission when working, and usually use clamping devices to install and fix semiconductor lasers.

[0003] A pulse laser with patent announcement number CN218783345U in the prior art includes a base, a fixed base and a clamping module, the fixed base is fixedly connected to the base, the clamping module includes a movable base, a tension spring, a slide rail, a moving block and a guide arc plate, the tension spring is arranged in the moving cavity, the two ends of the tension spring are respectively connected to the base and the movable base, the slide rail is fixedly connected to the base and is located in the moving cavity, the moving block is fixedly connected to the movable base and is located on the outer side wall of the movable base, and the moving block is slidably arranged in the slide rail, the guide arc plate is fixedly connected to the fixed base and is located above the fixed base, by placing the pulse laser on the fixed base and the movable base Between the fixed seat and the movable seat, under the action of the tension spring, the movable seat is always in contact with the outer wall of the pulse laser, so as to fix the pulse laser, thereby preventing the pulse laser from being compressed between the fixed seat and the movable seat, which may cause damage to the pulse laser. However, there are still the following deficiencies in actual use: in order to ensure the accuracy of laser emission, the laser emission angle and height need to be continuously adjusted during use. After the existing clamping device fixes the laser, it is not easy to adjust the emission angle of the laser, and the clamping device is usually fixedly connected to the workbench, which makes it difficult to adjust the emission height of the laser, resulting in poor practicality of the laser.

[0004] Therefore, a clamping device that is easy to adjust is needed to solve the problem in the prior art that it is difficult to adjust the emission angle and the emission height after the laser is fixed on the clamping device. Utility Model Content

[0023] The rotating mechanism 5 includes an installation cavity 51, which is opened inside the workbench 4. A rotating shaft 52 is rotatably connected between the top and bottom surfaces inside the installation cavity 51. A worm gear 53 is tightly sleeved on the outer surface of the rotating shaft 52. A worm 54 meshing with the worm gear 53 is rotatably connected between the two end walls inside the installation cavity 51. The outer wall of one end of the worm 54 rotates through the outer wall of one end of the workbench 4 and is coaxially fixedly connected with a handwheel 55.

[0024] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth specifically explaining that the lifting assembly 7 includes a U-shaped groove 71, which is opened inside the support column 1 and connected to the slide groove 2, and mounting grooves 72 are opened on both side walls inside the U-shaped groove 71, and springs 73 are fixedly connected to one side wall of the two mounting grooves 72, and a connecting column 74 is fixedly connected to one side of the spring 73, and an L-shaped plate 75 is fixedly connected to the outer wall of the connecting column 74 on the side away from the spring 73, and a limit block 76 matching the limit groove 8 is fixedly connected to the outer wall of the vertical section of the L-shaped plate 75 away from the connecting column 74, and an arc block 77 is fixedly connected to the outer wall of one side of the horizontal section of the L-shaped plate 75, and a rotating rod 78 is rotatably connected to the center of one end wall of the horizontal section inside the U-shaped groove 71, and rotating plates 79 arranged in an inclined shape are fixedly connected on both sides of the outer surface of the rotating rod 78, and the outer wall of one end of the rotating rod 78 rotates through the outer wall of one end of the support column 1 and is coaxially fixedly connected to a rotating wheel 710.

[0025] Further as Figure 1 As shown, it is worth explaining in detail that two parallel fixed plates 9 are fixedly connected to the top of the turntable 6, and electric push rods 10 are fixedly connected to the center of the outer wall of one side close to the two fixed plates 9, and the output end of the electric push rod 10 is fixedly connected to a clamping plate 11.

[0026] Further as Figure 1 As shown, it is worth explaining in detail that the bottom surface of the support column 1 is fixedly connected to the base 12, and the top surface of the workbench 4 is provided with a plurality of angle lines 13 distributed in a circle.

[0027] Further as Figure 3 and Figure 4 As shown, it is worth explaining in detail that the top end of the rotating shaft 52 rotates through the top surface of the workbench 4 and is coaxially fixedly connected with the bottom end of the turntable 6. The turntable 6 is rotated by the rotation of the rotating shaft 52. The outer surface of the connecting column 74 is slidably connected with the inner surface of the mounting groove 72, thereby improving the stability of the connecting column 74 when sliding in the mounting groove 72.

[0028] Further as Figure 2 and Figure 4As shown, it is worth explaining in detail that the two limit blocks 76 are movably inserted into the corresponding two limit grooves 8 to limit the slide rod 3, and the two rotating plates 79 are symmetrically distributed and the outer wall on the side away from the rotating rod 78 is set to be arc-shaped, so that the rotating plate 79 can push the arc block 77 to move when it rotates.

[0029] In summary: when the clamping device is in use, first place the laser on the top of the turntable 6 and between the two clamping plates 11, turn on the two electric push rods 10 to push the two clamping plates 11 closer to each other, and the two clamping plates 11 clamp and fix the laser. When the emission angle of the laser needs to be adjusted, turn the hand wheel 55 to drive the worm 54 to rotate. Under the action of the thread, the worm 54 drives the worm wheel 53 to rotate, and then the rotating shaft 52 drives the turntable 6 to rotate on the top surface of the workbench 4. By observing the position of the emission end of the laser on the angle line 13 on the top surface of the workbench 4, the emission angle of the laser can be accurately adjusted. The operation is simple, and the problem of difficulty in adjusting the emission angle after the laser is fixed on the clamping device is effectively avoided.

[0030] When it is necessary to adjust the emission height of the laser, the rotating wheel 710 is rotated to drive the rotating rod 78 to rotate, and the rotating rod 78 drives the two rotating plates 79 to rotate to a horizontal state. When the two rotating plates 79 rotate, they push the two arc blocks 77 to drive the two L-shaped plates 75 to move away from each other, and at the same time, the connecting column 74 slides inside the mounting groove 72, and the spring 73 is forced to shrink. At this time, the two limit blocks 76 are separated from the corresponding two limit grooves 8, and the limit on the slide bar 3 is released. Under the cooperation of the slide groove 2 and the slide bar 3, the workbench 4 is pushed upward to adjust the emission height of the laser. After reaching the required height, the rotating wheel 710 is released, and the shrinking spring 73 pushes the connecting column 74 to move, so that the L-shaped plate 75 pushes the limit block 76 to insert into the corresponding limit groove 8, and the adjusted slide bar 3 is re-limited to achieve the adjustment of the emission height of the laser. The operation is convenient and effectively avoids the problem that the emission height of the laser is not easy to adjust after being fixed on the clamping device.

[0031] The electric push rod 10 can be purchased on the market. The electric push rod 10 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
