Description

Technical Field

[0001] This utility model relates to the field of photoelectric autocollimator technology, and in particular to a focusing photoelectric autocollimator structure. Background Technology

[0002] A focusing photoelectric autocollimator is a precision optical instrument used to measure small angular deviations. It is widely used in precision machinery, optical processing, metrology, and other fields to detect geometric quantities such as straightness, flatness, and perpendicularity. This instrument combines the principle of optical autocollimation with photoelectric conversion technology to achieve high-precision angle measurement. Its components include an optical system (including optical elements such as a light source, objective lens, and beam splitter, responsible for generating and processing light, forming the basis for the instrument's measurement), a photoelectric conversion system (usually using a CCD or CMOS photodetector to convert optical signals into electrical signals for subsequent data processing), and a data processing system (which acquires, processes, and analyzes the electrical signals output by the photoelectric conversion system in real time, calculates the angle value of the measured plane, and displays the result).

[0003] Under current technological conditions, existing photoelectric autocollimators have a significant problem: their lenses are directly exposed to the external environment when not in use. This leads to numerous adverse effects. As we know, the surrounding air is filled with various tiny dust particles. Since the lens has no protective measures, these dust particles easily adhere to the surface of the objective lens. Over time and with changes in the usage environment, the accumulation of dust becomes increasingly severe. When measurement operations are performed, this dust adhering to the lens alters the propagation path of light, causing scattering and refraction of the light entering the instrument. This severely interferes with the instrument's accurate capture and analysis of light, ultimately affecting the accuracy of the instrument's measurements. Based on this, a focusing photoelectric autocollimator structure is proposed. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model proposes a focusing photoelectric autocollimator structure.

[0005] The technical solution of this utility model is implemented as follows: a focusing photoelectric autocollimator structure, comprising:

[0006] A base plate, on the upper surface of which the photoelectric autocollimator body is fixed;

[0007] Two side strips are symmetrically and rotatably disposed on both sides of the measuring end of the photoelectric autocollimator body. The ends of the two side strips are provided with a front baffle, which can move closer to or further away from the side strips through a movable structure.

[0008] A sealing and wiping component, which can block the detection end of the photoelectric autocollimator body, and the sealing and wiping component can be rotatably mounted on the front baffle.

[0009] Preferably, the movable structure includes a protruding plate vertically fixed to the inner wall of the side strip, and an electric telescopic rod is installed between the protruding plate and the front baffle.

[0010] Preferably, the end of the side strip is provided with a guide groove, and both ends of the front baffle facing the side strip are fixed with guide strips, which are inserted into the guide grooves.

[0011] Preferably, a perforation is provided in the middle of the front baffle, and an annular groove is provided inside the perforation.

[0012] Preferably, the sealing and wiping component includes a wiping head that can be embedded in the end of the photoelectric autocollimator body. One end of the wiping head is fixed with a through rod, which passes through a through hole, and the outer wall of the through rod is fixed with an annular protrusion that slides into the annular groove.

[0013] Preferably, a connecting strip is connected to the end of the rod away from the wiping head, and a handwheel is installed at the end of the connecting strip.

[0014] Preferably, a deflection motor is mounted on the side wall of the base plate via a support strip, and the output end of the deflection motor is connected to the side strip via a connecting shaft.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In use, this utility model, through the setting of side plate, front baffle, moving structure and sealing wiping component, allows the side plate to be deflected when not in use, and then the moving structure to make the wiping head of the sealing wiping component seal the objective lens, which can block dust. Dust particles cannot easily enter the surface of the objective lens, thereby reducing the adhesion of dust on the objective lens. Moreover, the wiping head is located on the front side of the measuring end of the photoelectric autocollimator body and is in contact with the objective lens, which can provide a certain degree of buffer protection for the objective lens. During the storage or transportation of the instrument, the wiping head can absorb and disperse these external forces to a certain extent, reducing the possibility of objective lens damage and extending the service life of the objective lens and the entire instrument.

[0017] 2. In use, the rotatable sealing and wiping component of this utility model allows the wiping head to be rotated by the handwheel, thereby effectively removing dust, oil and other impurities attached to the surface of the objective lens, ensuring the cleanliness of the objective lens. Moreover, this rotational cleaning method can improve cleaning efficiency compared to manually wiping the surface of the objective lens back and forth. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figure 1-Figure 4The illustrated focusing photoelectric autocollimator structure includes a base plate 1, side strips 3, and a sealing and wiping component 7. The autocollimator also features a built-in focusing structure, which is a conventional focusing design and existing technology; its specific structure will not be described in detail here. The autocollimator body 2 is fixed to the upper surface of the base plate 1. Two side strips 3 are provided, symmetrically and rotatably positioned on both sides of the measuring end of the autocollimator body 2. A front baffle 4 is provided at the ends of both side strips 3. The front baffle 4 can move closer to or further away from the side strip 3 via a movable structure. The sealing and wiping component 7 can block the detection end of the photoelectric autocollimator body 2 so that the lens can be wiped by rotation in the blocked state. The sealing and wiping component 7 can be rotatably mounted on the front baffle 4 to achieve position adjustment. A deflection motor 8 is installed on the side wall of the base plate 1 via a support strip. The output end of the deflection motor 8 is connected to the side strip 3 via a connecting shaft. The output end of the deflection motor 8 can drive the side strip 3 to deflect upward or downward.

[0026] Among them, see Figure 1 and Figure 2 As shown, the moving structure includes a protruding plate 5 vertically fixed to the inner wall of the side strip 3. An electric telescopic rod 6 is installed between the protruding plate 5 and the front baffle 4. The electric telescopic rod 6 is a device that can precisely control the telescopic length, enabling the front baffle 4 to move stably. By activating the electric telescopic rod 6, the front baffle 4 can be driven to move along a specific direction. Since the front baffle 4 is connected to the sealing and wiping component 7, as the front baffle 4 moves, the sealing and wiping component 7 will gradually move away from the side strip 3. During this process, the sealing and wiping component 7 will also move accordingly, eventually detaching from the measuring end of the photoelectric autocollimator body 2.

[0027] See Figure 3 As shown, the end of the side strip 3 is provided with a guide groove 12, and both ends of the front baffle 4 facing the side strip 3 are fixed with guide strips 9. The guide strips 9 are inserted and cooperate with the guide groove 12. When the front baffle 4 moves, the guide strips 9 can only move within the path defined by the guide groove 12. This ensures that the moving direction of the front baffle 4 is always the predetermined direction and there will be no deviation or tilting.

[0028] See Figure 3 and Figure 4 As shown, a perforation 10 is provided in the middle of the front baffle 4, and an annular groove 11 is provided inside the perforation 10.

[0029] The sealing and wiping component 7 includes a wiping head 71 that can be embedded in the end of the photoelectric autocollimator body 2. One end of the wiping head 71 is fixed with a through rod 72, which passes through the through hole 10. The outer wall of the through rod 72 is fixed with an annular protrusion 73 that slides in the annular groove 11. The end of the through rod 72 away from the wiping head 71 is connected to a connecting strip 74, and a handwheel 75 is installed at the end of the connecting strip 74.

[0030] As described above, when the photoelectric autocollimator is not in use, the deflection motor 8 can be used to deflect the side strip 3 so that the sealing and wiping part 7 is positioned in front of the measuring end of the photoelectric autocollimator body 2. Then, the electric telescopic rod 6 is used to move the front baffle 4 toward the side strip 3 so that the wiping head 71 is embedded into the measuring end of the photoelectric autocollimator body 2 and contacts the objective lens. The wiping head 71 can be used to seal the objective lens, acting as a barrier to physically block dust. Dust particles cannot easily enter the objective lens surface, thus reducing dust adhesion on the objective lens. This is crucial for maintaining the cleanliness and accuracy of the instrument in the long term. Furthermore, the wiping head 71, being in front of the measuring end of the photoelectric autocollimator body 2 and in contact with the objective lens, can provide a certain degree of buffer protection for the objective lens. During instrument storage or transportation, it may be subject to slight collisions or vibrations, and the wiping head 71 can absorb and disperse these external forces to a certain extent, reducing the possibility of objective lens damage and extending the service life of the objective lens and the entire instrument.

[0031] Secondly, when it is necessary to clean the objective lens, the wiping head 71 is first brought into contact with the objective lens at the measuring end of the photoelectric autocollimator body 2. Then, the connecting bar 74 can be rotated using the handwheel 75, which in turn rotates the wiping head 71, thereby effectively removing dust, oil and other impurities attached to the surface of the objective lens, ensuring the cleanliness of the objective lens. Moreover, this rotational cleaning method can improve cleaning efficiency compared to manually wiping the surface of the objective lens back and forth.

[0032] When the wiping head 71 rotates to wipe, the annular protrusion 73 moves within the annular groove 11, which helps to enhance the structural stability of the wiping head 71 when it rotates.

[0033] When the photoelectric autocollimator needs to be used, the electric telescopic rod 6 is used to move the front baffle 4 away from the side strip 3 so that the wiping head 71 is disengaged from the measuring end of the photoelectric autocollimator body 2. Then, the deflection motor 8 is used to deflect the side strip 3 so that the front baffle 4 with the sealing wiping part 7 is deflected to not block the measuring end of the photoelectric autocollimator body 2. Then it can be used.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
