Description

Technical Field

[0001] The utility model belongs to the technical field of cylindrical prism production, and particularly relates to a cylindrical prism production clamping device. Background Art

[0002] A cylindrical prism is an optical element that is cylindrical in shape and has one or more facets. This type of prism is often used to split a beam of light into multiple parts, or to combine multiple beams into one. This type of prism is commonly used in various optical instruments, such as telescopes, microscopes, and cameras.

[0003] After production, the cylindrical prism needs to be fixed with a clamping assembly. After being fixed by the clamping assembly, the cylindrical prism is polished, cut, and other operations are performed.

[0004] The existing clamping assembly includes a driving assembly and a fixing plate. The driving assembly is generally composed of an electric push rod, and the electric push rod drives the fixing plate to fix the cylindrical prism, thereby facilitating subsequent operations.

[0005] However, existing cylindrical prisms are composed of a cylinder with facets arranged on the cylinder. The facets are irregular. When fixed by a fixing plate, the fixing plate cannot completely contact the facets, resulting in insufficient friction, which makes it easy to fall off during subsequent processing.

[0006] At the same time, cylindrical prisms have many different models, that is, their cylindrical diameters are different. When the existing clamping components are used to clamp large-sized cylindrical prisms, since the area of ​​the fixing plate is fixed, some large-diameter cylindrical surfaces are exposed outside during fixing, which also leads to insufficient friction and is easy to fall off during subsequent processing.

[0007] To this end, we have proposed a cylindrical prism production clamping device, which not only fixes cylindrical prisms of different models to improve the clamping effect, but also makes the fixing surface more comprehensive, thereby improving the fixing effect. Utility Model Content

[0008] The utility model aims to provide a house rental publicity column, which is not only low in cost, but also can remove impurities and is easy to replace paper publicity paper, thus achieving the effect of saving time and labor.

[0009] The technical solutions adopted in this utility are as follows:

[0010] A cylindrical prism production clamping device, comprising a mounting shell, wherein the mounting shell is provided with two circular grooves and a plurality of through grooves, each of the circular grooves is provided with a rotating assembly, and the rotating assembly is provided with a second meshing tooth;

[0011] The inner wall of each through slot is rotatably provided with a rotating rod and fixedly provided with a sliding block, the rotating rod is provided with a first gear and two second gears meshing with second meshing teeth, the sliding block is arranged in a slide slot on one side, the slide slot is opened in a frame located inside the through slot, the inner wall of the frame is provided with a first meshing tooth, the first meshing tooth is meshed with the first gear, and a fixing component is provided at the bottom of each frame.

[0012] Furthermore, L-shaped fixing rods are provided on both sides of the frame, and fixing grooves corresponding to the positions of the L-shaped fixing rods are provided on the mounting shell.

[0013] Furthermore, the sliding block matches the sliding groove.

[0014] Furthermore, the rotating assembly includes a manual ring rotatably arranged inside the circular groove, the manual ring is connected to the rotating ring through a connecting rod, and the rotating ring is provided with second meshing teeth inside.

[0015] Furthermore, the fixing assembly includes a support rod connected to the bottom of the frame, an arc-shaped plate is installed at the bottom of the support rod, a plurality of through holes are opened on the arc-shaped plate, a movable rod is arranged inside each through hole, a limiting plate is arranged at the top of the movable rod, a fixed plate is arranged at the bottom of the movable rod, and a spring is sleeved on the movable rod, and the spring is located between the arc-shaped plate and the fixed plate.

[0016] Furthermore, the fixing plate is provided with an anti-slip surface.

[0017] The technical effects achieved by this utility model are:

[0018] 1. Place the cylindrical prism inside the mounting shell, and then rotate the rotating assembly. When the rotating assembly rotates, it drives the two second meshing teeth to rotate. The second meshing teeth drive the second gear to rotate. The second gear drives the first gear to rotate through the rotating rod. When the first gear rotates, it drives the first meshing teeth to move the frame up and down. In order to maintain the stability of the up and down movement, a slide groove is set to move on the slider, so that the up and down movement can be stable. At the same time, the frame drives the fixed assembly to move inside the mounting shell, so that the cylindrical prism is clamped and fixed by the fixed assembly. Such a setting can adapt to the fixation of cylindrical prisms of different diameters and models.

[0019] 2. When the frame moves downward, the fixed plate contacts the cylindrical prism, and then as the pressure increases, the fixed plate drives the movable rod to move upward and squeeze the spring. At the same time, since the cylindrical prism has many prisms (that is, many irregular places), multiple movable rods form a fixed surface that is the same as the irregular places. This fixed surface can form different shapes. Because the force applied to the irregular surface is also different, the force applied to the movable rod is also different. At the same time, because the movable rod can move up and down, different fixed surfaces can be formed, so that the cylindrical prism can be fixed. Compared with the existing technology, the fixed surface is more comprehensive, thereby improving the fixing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0027] like Figure 1-4 As shown, the technical solution adopted by the utility model is as follows: a cylindrical prism production clamping device, comprising a mounting shell 1, the mounting shell 1 is provided with two circular grooves 2 and a plurality of through grooves 3, each circular groove 2 is provided with a rotating assembly, and the rotating assembly is provided with a second meshing tooth 4;

[0028] The inner wall of each through slot 3 is rotatably provided with a rotating rod 5 and fixedly provided with a sliding block 6. The rotating rod 5 is provided with a first gear 7 and two second gears 8 meshing with the second meshing teeth 4. The sliding block 6 is arranged on one side in a slide groove 9. The slide groove 9 is opened in a frame 10 located inside the through slot 3. The sliding block 6 matches the slide groove 9. Note that the sliding block 6 here is fixed. When the frame 10 moves, the slide groove 9 can move on the sliding block 6.

[0029] The inner wall of the frame 10 is provided with a first meshing tooth 11 , which meshes with the first gear 7 , and a fixing component is provided at the bottom of each frame 10 .

[0030] The above working principle is: first, place the cylindrical prism inside the mounting shell 1, and then rotate the rotating component. When the rotating component rotates, it drives the two second meshing teeth 4 to rotate, and the second meshing teeth 4 drive the second gear 8 to rotate. The second gear 8 drives the first gear 7 to rotate through the rotating rod 5. When the first gear 7 rotates, it drives the first meshing tooth 11 to make the frame 10 move up and down. In order to maintain the stability of the up and down movement, the slide groove 9 is set to move on the slider 6, so that the up and down movement can be stable. At the same time, the frame 10 drives the fixing component to move into the mounting shell 1, so that the cylindrical prism is clamped and fixed by the fixing component. Such a setting can adapt to the fixing of cylindrical prisms of different diameters and models.

[0031] In order to ensure that the first gear 7 can drive the frame 10 to move, the first meshing teeth 11 are arranged on one side of the inner wall of the frame 10, but not on the other side, so that the frame 10 can be driven to move up and down when the first gear 7 rotates.

[0032] At the same time, the frame 10 is set as follows Figure 4 As shown, the bottom and the top are both sealed structures. The advantage of this arrangement is that it can prevent the over-flowing from forming and can also achieve the limiting effect.

[0033] Moreover, L-shaped fixing rods 12 are provided on both sides of the frame 10, and fixing grooves corresponding to the positions of the L-shaped fixing rods 12 are opened on the mounting shell 1. When clamping and fixing, the frame 10 moves downward, thereby driving the L-shaped fixing rods 12 to enter the fixing grooves for support and limitation, which can provide a certain amount of friction to prevent the frame 10 from sliding due to vibration.

[0034] like Figure 3As shown, the rotating assembly includes a manual ring 13 rotatably arranged inside the circular groove 2, the manual ring 13 is connected to a rotating ring 14 through a connecting rod, and a second meshing tooth 4 is arranged inside the rotating ring 14. People rotate the manual ring 13 inside the circular groove 2, thereby driving the rotating ring 14 to rotate through the connecting rod, and the rotating ring 14 drives the second meshing tooth 4 to rotate the second gear 8, so that the fixed assembly can clamp and fix the cylindrical prism.

[0035] The manual ring 13 is convenient for people to rotate, and people can observe the subsequent fixing effect.

[0036] It should be noted that: because two groups of circular grooves 2 are set, two groups of manual rings 13 and rotating rings 14 are set. The reason for setting two groups is that the stability of rotation can be guaranteed. If only one group is set, only one direction has the force to drive the rotation, which increases the friction and makes it difficult to rotate. At the same time, the two rotating forces are even, so that the movement is smooth.

[0037] like Figure 4 As shown, the fixing assembly includes a support rod 16 connected to the bottom of the frame 10, an arc plate 17 is installed at the bottom of the support rod 16, a plurality of through holes are opened on the arc plate 17, a movable rod 19 is arranged inside each through hole, a limiting disk is arranged on the top of the movable rod 19, a fixed disk is arranged at the bottom of the movable rod 19, and a spring 20 is sleeved on the movable rod 19, and the spring 20 is located between the arc plate 17 and the fixed disk.

[0038] The working principle of the above-mentioned fixing assembly is as follows: when the frame 10 moves downward, the fixing plate contacts the cylindrical prism, and then as the pressure increases, the fixing plate drives the movable rod 19 to move upward and squeezes the spring 20. At the same time, since the cylindrical prism has many prism shapes (that is, many irregular places), multiple movable rods 19 form a fixed surface that is the same as the irregular places. This fixed surface can form different shapes. Because the force applied to the irregular surface is also different, the force applied to the movable rod 19 is also different. At the same time, because the movable rod 19 can move up and down, different fixed surfaces can be formed, so that the cylindrical prism can be fixed. Compared with the prior art, the fixed surface is more comprehensive, thereby improving the fixing effect.

[0039] Among them, the fixing plate is provided with an anti-slip surface, which can increase the friction force and prevent shaking when clamping and fixing.

[0040] When disassembling later, it is only necessary to rotate the manual ring 13 inside the circular groove 2, thereby driving the second meshing tooth 4 to rotate the second gear 8, and the second gear 8 drives the first gear 7 to rotate through the rotating rod 5, so that the frame 10 drives the arc plate 17 to move upward, so that the fixed plate no longer fixes the cylindrical prism, thereby completing the disassembly.

[0041] The working principle of the utility model is as follows: firstly, a cylindrical prism is placed inside the mounting shell 1, and people rotate the manual ring 13 inside the circular groove 2, thereby driving the rotating ring 14 to rotate through the connecting rod, and the rotating ring 14 drives the second meshing tooth 4 to rotate the second gear 8, and the second gear 8 drives the first gear 7 to rotate through the rotating rod 5, and when the first gear 7 rotates, it drives the first meshing tooth 11 to move the frame 10 up and down. In order to maintain the stability of the up and down movement, the sliding groove 9 is set to move on the slider 6, so that the up and down movement can be stable, and at the same time, the frame 10 drives the fixing component to move into the mounting shell 1, so that the cylindrical prism is clamped and fixed by the fixing component. Such a setting can adapt to different Cylindrical prisms of the same diameter but different models are fixed. When the frame 10 moves downward, the fixed plate contacts the cylindrical prism. Then, as the pressure increases, the fixed plate drives the movable rod 19 to move upward and squeeze the spring 20. At the same time, since the cylindrical prism has many prisms (that is, many irregular places), multiple movable rods 19 form a fixed surface that is the same as the irregular places. This fixed surface can form different shapes. Because the force-bearing places of the prism irregular surface are also different, the forces applied to the movable rod 19 are also different. At the same time, because the movable rod 19 can move up and down, different fixed surfaces can be formed, so that the cylindrical prism can be fixed. Compared with the prior art, the fixed surface is more comprehensive, thereby improving the fixing effect. The device can not only fix cylindrical prisms of different models, but also has a more comprehensive fixed surface, thereby improving the fixing effect.

[0042] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
