[0019] like Figure 1-2 As shown, the utility model discloses an optical device assembly limiting tool, which includes a base 1, a side pressure block 2, a slide bar 3, a moving component 4 and a pressing component 5. The base 1 is provided with a U-shaped limiting groove 8 extending inward along its first end, and the first side of the base 1 is provided with an insertion port 9 arranged in a transverse direction. The side pressure block 2 is slidably mounted on the second side of the base 1, and the slide bar 3 is arranged at the first end of the base 1. The first end of the slide bar 3 is slidably connected with the side pressure block 2, and the second end of the slide bar 3 passes through the insertion port 9 and is slidably connected with the inner wall of the insertion port 9. The moving component 4 is used to control the side pressure block 2 and the slide bar 3 to move toward the optical device, and the pressing component 5 is used to limit the optical device from moving up and down. That is, the base 1, the side pressure block 2 and the slide bar 3 can form positioning grooves of different specifications according to the sizes of optical devices of different specifications.
[0020] When it is necessary to position the optical device, the staff can first place the optical device in the U-shaped limiting groove 8, and the edge of the optical device fits the bottom of the U-shaped limiting groove 8 on the first side of the base 1, that is, the optical device fits the first side of the base 1 and the second end of the base 1. Then the staff uses the moving component 4 to control the side pressure block 2 to move toward the first side of the base 1. During the movement, the slide bar 3 continuously passes through the insertion port 9 until the side pressure block 2 and the base 1 clamp the two sides of the optical device. Then the moving component 4 is used to control the slide bar 3 to move from the first end of the base 1 to the second end of the base 1. At this time, the slide bar 3 also slides in the insertion port 9 in this direction until the slide bar 3 and the base 1 clamp the two ends of the optical device. Finally, the staff uses the pressing component 5 to press the optical device to further limit the position of the optical device.
[0021] The utility model can accurately position optical devices of different sizes in the longitudinal and transverse directions by setting the base 1, the side pressure block 2 and the slide rod 3 to ensure their accurate positions, which helps to ensure the correct positions of the optical devices during the assembly process and improve the accuracy and quality of the assembly.
[0022] In one embodiment, the moving assembly 4 includes a first spiral fine-tuning head 41 and a second spiral fine-tuning head 42. The first spiral fine-tuning head 41 is installed on the second side of the base 1 and is used to control the side pressure block 2 to move toward the first side of the base 1, that is, the adjustment end of the first spiral fine-tuning head 41 is fixedly connected to the base 1, and its telescopic rod end is fixedly connected to the side pressure block 2. The second spiral fine-tuning head 42 is installed on the side pressure block 2 and is used to control the sliding rod 3 to move toward the second end of the base 1, that is, the adjustment end of the second spiral fine-tuning head 42 is fixedly connected to the side pressure block 2, and its telescopic rod end is fixedly connected to the sliding rod 3.
[0023] The staff can control the movement of the side pressure block 2 and the slide rod 3 by rotating the first spiral fine-tuning head 41 and the second spiral fine-tuning head 42, so that the tooling can achieve precise fine-tuning of the movement of the side pressure block 2 and the slide rod 3, while avoiding the movement or shaking of the optical device during the assembly process, thereby improving the stability and reliability of the assembly.
[0024] In one embodiment, a slide rail 6 is fixedly mounted on the side pressure block 2, and the slide rail 6 is slidably connected to the slide bar 3. The presence of the slide rail 6 enables the slide bar 3 to slide smoothly on the side pressure block 2, which helps to ensure the stability and accuracy of the optical device during the assembly process and reduce friction and instability during the sliding process.
[0025] In one embodiment, there are two pressing components 5, which are respectively arranged on the base 1 and the side pressing block 2. When the optical device is small, the staff can select one pressing component 5 to limit the optical device as needed. When the optical device is large, the staff can use two pressing components 5 to limit the two sides of the optical device at the same time to ensure the stability of the optical device in the vertical direction.
[0026] In one embodiment, the pressing assembly 5 includes a slider 51, a rotating column 52, a fixed plate 53, a sliding column 54, a pressure plate 55 and a spring 56. The slider 51 is slidably connected to the base 1 or the side pressure block 2, the rotating column 52 is rotatably connected to the slider 51 along the longitudinal direction, the fixed plate 53 is fixedly installed on the top of the rotating column 52 along the transverse direction, the sliding column 54 passes through the sliding column 54 and is slidably connected to the sliding column 54, the pressure plate 55 is fixedly installed at the bottom of the sliding column 54 and contacts the optical device, and the spring 56 makes the sliding column 54 have a tendency to move downward.
[0027] In the initial state, the pressing plate 55 is located on the base 1. When using the pressing assembly 5, first slide the slider 51 to a suitable position. In the embodiment, a third spiral fine-tuning head can be provided to precisely adjust the slider 51. The spring 56 is sleeved on the sliding column 54, and the two ends of the spring 56 are respectively fixedly connected to the pressing plate 55 and the fixing plate 53. Then the staff lifts the sliding column 54 upwards, rotates the fixing plate 53, and after the pressing block is located above the optical device, releases the sliding column 54, and the pressing plate 55 moves downward under the action of the spring 56 to press the optical device.
[0028] In one embodiment, a wedge 7 is further included, and the wedge 7 is engaged with the inner wall of the insertion port 9. In the embodiment, the wedge 7 is in a step-shaped shape with a trapezoidal cross section, and can be inserted into the insertion port 9. As the wedge 7 goes deeper, its inclined surface will form an increasingly close contact with the inner wall of the insertion port 9, further fixing the second end of the slide bar 3.
[0029] The workflow of this embodiment is as follows:
[0030] The staff can first place the optical device in the U-shaped limiting groove 8, and the edge of the optical device fits the bottom of the U-shaped limiting groove 8 on the first side of the base 1, that is, the optical device fits the first side of the base 1 and the second end of the base 1. Then the staff adjusts the first spiral fine-tuning head 41 to make the side pressure block 2 move toward the first side of the base 1, and at the same time, the rod body of the slide bar 3 continuously passes through the insertion port 9 until the side pressure block 2 and the base 1 clamp the two sides of the optical device. The staff then adjusts the second spiral fine-tuning head 42, and the slide bar 3 moves from the first end of the base 1 to the second end of the base 1. At this time, the slide bar 3 also slides in the insertion port 9 in this direction until the slide bar 3 and the base 1 clamp the two ends of the optical device, and then inserts the wedge 7 into the insertion port 9 on the side corresponding to the first end of the slide bar 3 and the base 1 to fix the second end of the slide bar 3.
[0031] Finally, the staff uses the pressing assembly 5. When the optical device is small, the staff can select one pressing assembly 5 to limit the optical device as needed. When the optical device is large, the staff can use two pressing assemblies 5 to limit the two sides of the optical device at the same time to ensure the stability of the optical device in the vertical direction. When using the pressing assembly 5, first slide the slider 51 to a suitable position, then lift the sliding column 54 upward, rotate the fixing plate 53, so that the pressing block is located above the optical device, release the sliding column 54, and under the action of the spring 56, the pressing plate 55 moves downward to press the optical device.
[0032] The utility model can accurately position optical devices of different sizes in the longitudinal and transverse directions by setting the base 1, the side pressure block 2 and the slide rod 3 to ensure their accurate positions, which helps to ensure the correct positions of the optical devices during the assembly process and improve the accuracy and quality of the assembly.
