DETAILED DESCRIPTION

[0020] The utility model will be further described below in conjunction with the accompanying drawings.

[0021] like Figure 1-4As shown, a device for adjusting the lens angle to assist in clear optical imaging of the utility model comprises a base 13, a mounting platform 11 is longitudinally arranged on the base 13, a rotating tool 7 is arranged on one side of the mounting platform 11, and a suction pen 6 is arranged on the rotating tool 7; a lens fixture 4 is also arranged on the base 13, and the lens fixture 4 can move on the base 13 to change the distance between it and the suction pen 6, specifically, a slide rail 2 is arranged on the base 13, and the lens fixture 4 is connected to the slide rail 2 through a slider. The rotating tool 7 comprises a coarse adjustment mechanism 71 and a fine adjustment mechanism, and the fine adjustment mechanism comprises a fine adjustment component 72 and a mounting seat 73 arranged on the mounting platform 11, and a micrometer 8 is arranged on the mounting seat 73, and the micrometer 8 is used to drive the rotating tool 7 to move; and a fine adjustment and coarse adjustment switching mechanism is also included.

[0022] The mounting seat 73 is also provided with a limit mechanism 10, which is used to limit the adjustment range of the micrometer 8. The fine adjustment component 72 is provided with a column 74, which is used to cooperate with the micrometer 8 to drive the rotary tool 7 to move. The limit mechanism 10 is arranged opposite to the micrometer 8, and the column 74 is located between the limit mechanism 10 and the micrometer 8. The limit mechanism 10 can be a screw screwed on the mounting seat 73, one end of which passes through the mounting seat 73, and when screwed in, the distance between the micrometer 8 and its end can be reduced, thereby realizing the function of limiting the adjustment range of the micrometer 8. A knob can be arranged at the other end, and a spring can be arranged between the knob and the mounting seat, and the spring can apply additional force to the knob to ensure that the knob is not easy to loosen after being vibrated.

[0023] The coarse adjustment mechanism 71 is a cylinder or annular ring with steps, and the fine adjustment component 72 is an annular ring. The steps of the coarse adjustment mechanism 71 are located inside the fine adjustment component 72 and are coaxially arranged. The coarse adjustment and fine adjustment switching mechanism includes a switching knob 14 arranged on the side wall of the fine adjustment component 72. The switching knob 14 can lock or release the coarse adjustment mechanism 71 and the fine adjustment component 72. Specifically, the switching knob 14 is screwed into the side wall of the fine adjustment component 72 and can contact the outside of the step of the coarse adjustment mechanism located in the fine adjustment component 72. When tightened, the entire coarse adjustment mechanism 71 cannot rotate alone, but can only rotate with the fine adjustment component 72. The fine adjustment component 72 cooperates with the micrometer 8 to achieve high-precision rotation at a small angle, that is, to achieve fine adjustment of the lens at a small angle. When only coarse adjustment is required, the switching knob 14 is loosened to allow the coarse adjustment mechanism 71 to rotate alone. The coarse adjustment mechanism 71 has a large rotation range and is suitable for adjustment within a large range. When fine adjustment is required, the switching knob 14 is tightened and then the micrometer is used for fine adjustment.

[0024] The base 13 is provided with a tightening mechanism 3, and the tightening mechanism 3 is used to hold the lens fixture 4. Specifically, Figure 1 , 4The tightening mechanism 3 comprises a bracket 31 disposed on the base 13, and a push rod 32 is provided on the bracket 31, that is, the bracket 31 has a hole through which the push rod 32 can pass horizontally. One end of the push rod 32 is connected to a movable member 35 through an axis, and the movable member 35 is movably connected to a handle 34, and the handle 34 is disposed on the bracket 31 through a rotating shaft 33. Figure 1 As shown, when the tightening mechanism needs to be loosened, the handle 34 is pushed to the right, and the handle 34 rotates around its rotation axis 33. At this time, the handle 34 drives the movable member 35. One end of the movable member 35 is driven by the handle 34 to move, and the other end pulls the push rod 32, so that the push rod 32 moves axially to the right, and the tightening of the lens clamp 4 is released. When the lens clamp 4 needs to be tightened, the above steps are reversed to make the push rod 32 press against the side of the lens clamp 4.

[0025] The other end of the push rod 32 is provided with an adjusting component, and the adjusting component is used to adjust the length of the end of the push rod 32. Specifically, the adjusting component can be a screw rod screwed on the end of the push rod 32, and by adjusting the screwing length of the screw rod, the length of the screw rod exposed outside the push rod 32 can be adjusted to meet the tightening requirements of the lens clamp 4 in different situations, or to adjust the tightening force.

[0026] The base 13 is provided with a front positioning mechanism 9 and a rear positioning mechanism 1, which are used to limit the movement range of the lens fixture 4 on the base 13. The front positioning mechanism 9 and the rear positioning mechanism 1 can be commonly used limit blocks.

[0027] The suction pen 6 is connected to an external air source, and a gas interface identical to that of the suction pen 6 can be provided on the rotary tooling 7 .

[0028] The lens clamp 4 has a space for accommodating the lens, and the space has a detachable part. After removing the part, the lens is placed in the space, and then the detachable part is installed and fixed, such as by bolts, to clamp the lens.

[0029] The mounting platform 11, the rotating tool 7, and the suction pen 6 may have coaxial and through holes, which allow the staff to observe the imaging condition of the lens, and also to observe the imaging condition of the lens from the other end of the lens.

[0030] The use process of the utility model is as follows: install the lens 5 on the lens fixture 4, manually push it to the position of the suction pen 6, make the lens and the suction pen 6 stick together, then turn on the air source, and make the suction pen 6 suck the lens. Adjust the position of the top tightening mechanism 3 and the front positioning mechanism 9, lock the screws to fix the position of the lens fixture 4, then loosen the switching knob 14 first, let the coarse adjustment mechanism 71 and the fine adjustment component 72 not be locked, only turn the coarse adjustment mechanism to adjust the angle, when it is observed that the lens imaging is about to reach a clear state, tighten the switching knob 14, and then use the micrometer 8 to push the fine adjustment component 72 and the coarse adjustment mechanism 71 to rotate at a slight angle at the same time, until the observation lens imaging is clear, then glue the lens, and then loosen the top tightening mechanism 3, let the lens fixture 4 withdraw from the working position, open the lens fixture 4 to remove the lens, and then repeat the above work to adjust the next lens.

[0031] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
