DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely explain the technical solutions in the embodiments of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict, and the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0020] It should be noted that the descriptions of the present invention regarding directions such as "left", "right", "left side", "right side", "upper", "lower", "top", and "bottom" are all defined based on the relationship between the orientations or positions shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the structure must be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention. In the description of the present invention, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0021] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Specific implementation method: Referring to the accompanying drawings, this embodiment is described, providing a lens installation auxiliary device, comprising: A main frame 1, with an autocollimator connected to one side and a reflector 10 on the other side; The supporting platform 2 is slidably mounted on the main frame 1 and can rotate around the connection with the main frame 1; The tooling part 3 is connected to the support platform 2 on one side and to the lens barrel 7 on the other side; An adjustment platform 6 connected to the reflector side of the main frame 1, a through hole is provided in the middle of the adjustment platform 6, and the reflector 10 is provided in the space formed by the through hole and the main frame 1; A loading platform 5, one side of which is fixed on the adjusting platform 6, and the side away from the adjusting platform 6 is used for connecting the lens 8; The supporting platform 2, the tooling part 3, the adjusting platform 6 and the loading platform 5 form an optical path, so that the light from the autocollimator is irradiated onto the reflector.

[0023] Rotate the support platform 2 so that the side connected to the tooling part 3 is flipped upward. The angle with the horizontal plane can be set according to the user's habit to facilitate the installation of the tooling part 3. After the tooling part 3 is installed on the support platform 2 and the lens barrel 7 is connected to the tooling part 3, the support platform 2 will continue to be rotated so that the lens barrel 7 faces downward to facilitate up and down movement. A level ruler or a more accurate measuring device can be used to measure whether the lens barrel 7 is vertically downward, so as to improve the installation accuracy later.

[0024] The lens 8 is placed on the loading platform 5, and the position of the lens 8 and the loading platform 5 is adjusted to keep the center close. The autocollimator is turned on to allow light to pass through the lens 8 and then irradiate the reflector 10, and the position of the lens 8 is fine-tuned by adjusting the platform 6. After the lens 8 is concentric with the lens barrel 7, the support platform 2 is moved downward, and the support platform 2 drives the tooling part 3 and the lens barrel 7 to move downward, and the lens 8 enters the lens barrel 7, and the upper pressing ring 9 is installed. The traditional large lens installation is all through placing the lens barrel, and then placing the lens from top to bottom. The lens is easy to place, but it is not easy to adjust the position of the lens. The coaxiality of the lens barrel and the lens needs to be repeatedly installed and tested. The present invention places the autocollimator on the upper part, which can measure the coaxiality of the lens in real time and is also convenient for adjusting the position of the lens.

[0025] In this embodiment, the main frame 1 includes a lower platform 1-1, a column 1-2 and an upper platform 1-3. A reflector 10 is provided in the middle of the lower platform 1-1, and columns 1-2 are vertically provided on both sides of the lower platform 1-1. The upper platform 1-3 is fixed on the column 1-2, and an autocollimator is connected to the upper part of the upper platform 1-3.

[0026] The lower platform 1-1 is used to place the reflector 10 and the adjustment platform 6, the column 1-2 is used to support the upper platform 1-3, and an autocollimator is fixed on the upper part of the upper platform 1-3. The indicator light of the autocollimator passes through the supporting platform 2, the tooling part 3, the lens 8, and the adsorption seat 5, and then shines on the reflector 10, and then reflects back to the autocollimator.

[0027] In this embodiment, the support platform 2 includes a slider 2-3, a screw 2-4 and a support seat 2-10. The slider 2-3 is rotatably connected to the support seat 2-10, and the slider 2-3 is slidably connected to the slide rail 1-5 provided on the column 1-2. The two ends of the screw 2-4 are respectively rotatably connected to the column 1-2 and the upper platform 1-3, and the screw 2-4 is threadedly connected to the slider 2-3.

[0028] A screw motor 2-5 is provided at the end of the screw 2-4. The screw motor 2-5 rotates to drive the screw 2-4 to rotate. The screw 2-4 drives the slider 2-3 to slide up and down along the slide rail 1-5 provided on the column 1-2, thereby driving the support seat 2-10 to slide synchronously. The sliding of the support seat 2-10 drives the tooling part 3 to move, and the tooling part 3 drives the lens barrel 7 to move. Rotating shafts 2-2 are symmetrically provided on both sides of the support seat 2-10. The rotating shafts 2-2 are inserted into the slider 2-3 and are rotatably connected to the slider 2-3. One of the rotating shafts 2-2 is connected to the flipping motor 2-6. The flipping motor 2-6 is fixed on the slider 2-3 on the same side. The rotation of the flipping motor 2-6 drives the rotating shaft 2-2 to rotate, and the rotation of the rotating shaft 2-2 drives the support seat 2-10 to rotate.

[0029] The tooling part 3 includes a positioning seat 3-1, a connecting part 3-2 and an internal thread 3-3. The positioning seat 3-1 is installed on a tooling connecting seat 2-9 provided on the supporting seat 2-10, and plays a positioning role to prevent a large installation deviation between the tooling part 3 and the supporting seat 2-10. The connecting part 3-2 is provided with a thread 3-3 inside for connecting with the end of the lens barrel 7. The connection method between the tooling part 3 and the lens barrel 7 is set according to the connection method between the lens barrel 7 and the main equipment, and the connection method between the connecting part 3-2 and the lens barrel 7. The size is also independently designed and processed according to the difference of the lens barrel 7, and the positioning seat 3-1 is a fixed design, which can ensure a fixed connection method with the tooling connecting seat 2-9, reducing the waste of parts and increased costs due to the change of the lens barrel 7 or the need to replace the supporting platform.

[0030] In this embodiment, the support seat 2 - 10 is also provided with a fastening device 4 for stably connecting the tooling part 3 and the lens barrel 7 .

[0031] The lens barrel 7 and the tooling part 3 are connected by threads, which is not stable enough. A fastening device 4 is added to add an axial force between the tooling part 3 and the lens barrel 7, so that the threaded connection is more tight and stable.

[0032] In this embodiment, at least two fastening devices 4 are provided. Preferably, two are provided and symmetrically arranged along the center of the support seat 2-10, which is conducive to symmetrically acting two axial forces between the lens barrel 7 and the tooling part 3, so that the axis of the lens barrel 7 is perpendicular to the mirror surface of the reflector 10, which is conducive to adjustment and installation. A positioning groove 2-7 is provided on the side of the support seat 2-10 away from the tooling part 3. The positioning groove 2-7 is used to install the fastening device 4 to prevent the symmetry of the two fastening devices 4 from having a large deviation due to the screw fixing method.

[0033] In this embodiment, the fastening device 4 includes a horizontal plate 4-1, a fastening block 4-3 and a fastening nail 4-4. The horizontal plate 4-1 is fixed to the vertical rod of the support seat 2-10. A fastening block 4-3 is slidably provided in the middle of the horizontal plate 4-1. The fastening block 4-3 is threadedly connected with a fastening nail 4-4. The fastening nail 4-4 is pressed against the end face of the lens barrel 7.

[0034] A slide groove 4-2 is provided on the horizontal plate 4-1, and the fastening block 4-3 moves along the slide groove 4-2, and at the same time drives the fastening nail 4-4 to move. When the axis of the fastening nail 4-4 moves to the end wall of the lens barrel 7, the fastening nail 4-4 can be tightened so that the two fastening nails 4-4 are tightened to the same length, or through a horizontal measuring device, the horizontality of the support seat 2-10 or the verticality of the axis of the lens barrel 7 can be measured while tightening, so as to ensure the accuracy of subsequent installation and reduce deviation.

[0035] In this embodiment, the loading platform 5 includes an adsorption platform 5-1, an adsorption seat 5-3 and an adsorption column 5-4. The adsorption seat 5-3 is fixed on the adsorption platform 5-1. The adsorption column 5-4 is rotatably connected to the adsorption seat 5-3. The adsorption column 5-4 is used to adsorb the lens 8.

[0036] In this embodiment, a channel 5-8 is provided inside the adsorption column 5-4 for discharging the gas between the adsorption lens 8 and the adsorption column 5-4.

[0037] In this embodiment, the adsorption seat 5-3 is provided with a cavity 5-7 connected to the channel 5-8, the adsorption platform 5-1 is provided with an air channel 5-6 inside, the air channel 5-6 is connected to the cavity 5-7, and the adsorption platform 5-1 is provided with an exhaust port 5-2 connected to the air channel 5-6.

[0038] The adsorption column 5-4 contacts the lens 8 to fix the lens 8. When placing the lens, the adsorption platform 5-1 needs to be adjusted to a horizontal position through the adjustment platform 6, and the lens is roughly adjusted to a position concentric with the adsorption platform 5-1, and then the adjustment platform 6 drives the adsorption platform 5-1 to move.

[0039] The principle of adsorption is that the exhaust port 5-2 is connected to the suction device, and the gas in the channel 5-8 passes through the cavity 5-7, then through the airway 5-6, and finally reaches the exhaust port 5-2. The lens 8 is fixed on the loading platform 5 by the air pressure difference, which is convenient for stably adjusting the angle and position of the lens and also prevents it from falling.

[0040] In this embodiment, the adjustment platform 6 includes an upper support platform 6-1, a cylinder 6-2, a cylinder seat 6-3 and a lower support platform 6-4. The upper support platform 6-1 is connected to the adsorption platform 5-1, one end of the cylinder is connected to the upper support platform 6-1, and the other end is connected to the cylinder seat 6-3. The cylinder seat 6-3 is rotatably connected to the lower support platform 6-4.

[0041] Preferably, six cylinders 6-2 are provided. By controlling the lengths of different cylinders 6-2, the horizontal position of the upper support platform 6-1 and its relative angle to the horizontal position are adjusted, thereby driving the position and angle of the loading platform 5, that is, adjusting the position and angle of the lens 8.

[0042] The indicator light emitted by the autocollimator passes through the positioning hole 1-4 set in the middle of the upper platform 1-3, the positioning hole 2-1 in the middle of the support seat 2-10, the middle of the tooling part 3, the lens barrel 7, the lens 8, the positioning hole 3-5 in the middle of the loading platform 5, and the positioning hole 4 6-5 set on the upper support platform 6-1 of the adjustment platform 6, and reaches the radiation mirror 10, and then returns to the autocollimator through reflection. The deviation between the reflected light and the center point is observed, and the position of the lens 8 is adjusted until the centers coincide. Then the lens barrel 7 moves downward to combine with the lens, and the pressure ring 9 is lifted upward to fix the lens 8. You can also first perform the gluing operation, apply non-volatile glue between the lens 8 and the lens barrel 7, fix them first, and then tighten the pressure ring 9.

[0043] The autocollimator and the air suction device are both existing technologies and can be reasonably connected and used according to actual selection.

[0044] The embodiments of the present invention disclosed above are only used to help illustrate the present invention. The embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. According to the content of this specification, many modifications and changes can be made. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
