Description

Technical Field

[0001] This invention belongs to the technical field of dual-head photoelectric autocollimator equipment, specifically relating to a dual-head photoelectric autocollimator. Background Technology

[0002] The dual-head photoelectric autocollimator is a high-precision measuring device. Through software-based digital filtering and CCD image processing, it achieves rapid two-dimensional measurement in two directions. It can be applied to the measurement of parallelism between two base planes. The structure of the dual-head photoelectric autocollimator includes one lens, two beam splitters A, beam splitter B, two CCD sensors, two light sources, two accelerometers, and a housing, as described in the Chinese patent for a novel dual-head photoelectric autocollimator with authorization announcement number C106403909A.

[0003] The lenses of existing dual-head photoelectric autocollimators are exposed when not in use, making them prone to dust accumulation on the objective lenses, which affects the accuracy of the instrument's measurements. Manually wiping the dust by hand can leave fingerprints on the lenses, which also affects the accuracy of the instrument's measurements. In addition, during use, the autocollimator and the reflector are usually placed on the same guide rail, and then the dual-head photoelectric autocollimator is calibrated. However, the traditional method of installing multiple bolts on the base and adjusting the height by rotating the bolts has low precision, large errors, and cannot guarantee the stability of the dual-head photoelectric autocollimator after adjustment. Summary of the Invention

[0004] The purpose of this invention is to provide a dual-head photoelectric autocollimator that can clean dust from the lens, with good cleaning effect, avoiding the impact of dust on the accuracy of instrument measurement, and also effectively protecting the lens.

[0005] The specific technical solution adopted by this invention is as follows:

[0006] A dual-head photoelectric autocollimator includes a main body, with objective lens tubes on both sides. Each objective lens tube contains a lens. A sealing cover is hinged to one side of each objective lens tube, and a mounting groove is formed on one side of the sealing cover. A through hole is formed in the middle of the outer wall of the sealing cover, and a pressing rod is movably connected inside the through hole. A limit slider is provided inside the through hole. An arc-shaped sliding groove is provided on the outer wall of the pressing rod, which is slidably connected to the limit slider. A first mounting plate is fixed to one end of the pressing rod extending into the mounting groove. Multiple telescopic rods are fixed to one side of the first mounting plate, and the other ends of the multiple telescopic rods are fixed to the same second mounting plate. A removable cleaning cotton is provided on one side of the second mounting plate. A pressing block is fixed to one end of the pressing rod extending outside the sealing cover. An annular plate, rotatably connected to the sealing cover, is sleeved on the outer wall of the pressing rod. A spring is provided on the outer wall of the pressing rod, located between the annular plate and the pressing block. An adjustment assembly is provided at the bottom of the main body of the photoelectric autocollimator.

[0007] Furthermore, the cleaning cotton is made of microfiber material.

[0008] Furthermore, the adjustment assembly includes an adjustment plate disposed below the main body of the photoelectric autocollimator, a movable groove is provided on the top of the adjustment plate, a movable block is fixed to the bottom wall of the main body of the photoelectric autocollimator and is slidably connected to the movable groove, a first lead screw is rotatably installed on the inner wall of the movable groove and is threadedly connected to the movable block, and a first rotating wheel is fixed at one end of the first lead screw extending outside the adjustment plate.

[0009] Furthermore, the top of the adjustment plate and both sides of the moving groove are provided with second sliding grooves, and the bottom of the photoelectric autocollimator body is provided with a second slider that is slidably connected to the second sliding groove.

[0010] Furthermore, a base plate is provided below the adjusting plate, and two fixing ears are fixed to the top of the base plate. Two rotating shafts are rotatably installed between the outer walls of the two fixing ears. Three sets of meshing gears are provided on the outer walls of the two rotating shafts. A second connecting rod is fixed to the outer wall of each of the gears. A first connecting rod that is rotatably connected to the adjusting plate is rotatably installed at the other end of the second connecting rod. A connecting shaft is fixed between the outer walls of the multiple second connecting rods on the same side. A third connecting rod is rotatably installed on the outer wall of the connecting shaft. A fixing block is provided at the top of the base plate, and a first sliding groove is opened at the top of the fixing block. A second lead screw is rotatably installed inside the first sliding groove. A first slider that is slidably connected to the first sliding groove is threaded onto the outer wall of the second lead screw, and the top of the first slider is rotatably connected to one end of the third connecting rod.

[0011] Furthermore, L-shaped plates are fixed on both sides of the top of the main body of the photoelectric autocollimator. A first magnet is provided on one side of the L-shaped plate, and a second magnet is provided on one side of the sealing cover, which is attracted to the first magnet by magnetic force.

[0012] Furthermore, the second mounting plate and the cleaning cotton are connected and fixed to each other by Velcro or magnets.

[0013] The technical effects achieved by this invention are as follows:

[0014] The cleaning cotton in this invention, by squeezing the pressing block, causes the pressing rod to move and rotate to one side, thereby rotating the cleaning cotton on the second mounting plate and cleaning the dust on the lens. The operation is simple, and the cleaning effect is good, preventing dust from affecting the accuracy of instrument measurements. The sealing cover protects the lens when the equipment is not in use, further preventing dust accumulation. The adjustment component facilitates the adjustment of the left-right position and vertical height of the photoelectric autocollimator body, improving the flexibility of the equipment and the adjustment effect, and shortening the adjustment time of the photoelectric autocollimator body.

[0022] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0023] Example 1

[0024] like Figure 1-4 As shown, a dual-head photoelectric autocollimator includes a main body 1. Objective lens tubes are provided on both sides of the main body 1. Lenses 2 are disposed inside the objective lens tubes. A sealing cover 3 is hinged to one side of the objective lens tube. A buckle is provided at the bottom of one side of the sealing cover 3, allowing it to be fixed to the objective lens tube after being closed. A mounting groove 4 is provided on one side of the sealing cover 3. A through hole 11 is provided in the middle of the outer wall of the sealing cover 3. A pressing rod 5 is movably connected inside the through hole 11. A limiting slider 12 is provided inside the through hole 11. The outer wall of the pressing rod 5 is provided with a sliding connection to the limiting slider 12. The connecting arc-shaped sliding groove 13 allows the pressing rod 5 to rotate and move to one side through the cooperation of the limiting slider 12 and the arc-shaped sliding groove 13 when the pressing rod 5 is pressed. A first mounting plate is fixed to one end of the pressing rod 5 extending into the mounting groove 4. Multiple telescopic rods are fixed to one side of the first mounting plate, and the other ends of the multiple telescopic rods are fixed to the same second mounting plate 6. A removable cleaning cotton 7 is provided on one side of the second mounting plate 6 to facilitate cleaning dust from the lens 2. A pressing block 8 is fixed to one end of the pressing rod 5 extending outside the sealing cover 3. The outer wall of the pressing rod 5... An annular plate 10, rotatably connected to the sealing cover 3, is fitted onto the outer wall of the pressing rod 5, located between the annular plate 10 and the pressing block 8. A spring 9 is installed between the annular plate 10 and the pressing block 8 to ensure that the pressing rod 5 remains in its initial position when no external force is applied. An adjustment assembly is provided at the bottom of the photoelectric autocollimator body 1. The structure is simple and easy to operate. When not in use, the objective lens tube can be covered by the sealing cover 3 to prevent dust from entering the lens 2 and affecting subsequent use. If dust is found on the lens 2, the sealing cover 3 can be closed first, and the cleaning cotton 7 can be made to contact and rotate with the lens 2 by pressing the pressing block 8. The dust on the surface is cleaned; the cleaning cotton 7 is made of microfiber material, which makes the dust removal effect of the cleaning cotton 7 better; L-shaped plates are fixed on both sides of the top of the photoelectric autocollimator body 1. A first magnet is set on one side of the L-shaped plate, and a second magnet is set on one side of the sealing cover 3, which is attracted to the first magnet. The sealing cover 3 is fixed after being opened by the magnetic attraction of the second magnet and the first magnet, thus preventing the normal use of the equipment; the second mounting plate 6 and the cleaning cotton 7 are connected and fixed to each other by Velcro or magnets, which makes it convenient to fix and remove the cleaning cotton 7, which is convenient and labor-saving.

[0025] Working principle: When cleaning dust on lens 2, the pressing block 8 presses the pressing rod 5. The pressing rod 5 rotates and moves to one side due to the cooperation of the upper limit slider 12 and the arc-shaped sliding groove 13. The pressing rod 5 drives the first mounting plate to move and rotate. The first mounting plate, in conjunction with the telescopic rod, drives the cleaning cotton 7 on the second mounting plate 6 to rotate and clean the dust on lens 2. When using the equipment, the sealing cover 3 can be flipped over so that the second magnet and the first magnet attract each other and fix the sealing cover 3. When not in use, the sealing cover 3 should be closed to prevent dust from sticking to lens 2.

[0026] Example 2

[0027] like Figure 1 , 2 As shown in Figure 5, the adjustment assembly includes an adjustment plate 14 located below the main body 1 of the photoelectric autocollimator. A movable groove 15 is formed on the top of the adjustment plate 14. A movable block 16, slidably connected to the movable groove 15, is fixed to the bottom wall of the main body 1 of the photoelectric autocollimator. A first lead screw 17, threadedly connected to the movable block 16, is rotatably mounted on the inner wall of the movable groove 15. A first rotating wheel is fixed to one end of the first lead screw 17 extending outside the adjustment plate 14. Rotation of the first lead screw 17 drives the movable block 16 to move, which in turn drives the main body 1 of the photoelectric autocollimator to move, facilitating the left-right movement of the main body 1. Second sliding grooves are formed on the top of the adjustment plate 14 and on both sides of the movable groove 15. A second slider, slidably connected to the second sliding groove, is provided at the bottom of the main body 1 of the photoelectric autocollimator, making the movement of the main body 1 of the photoelectric autocollimator relatively stable. A base plate 29 is located below the adjustment plate 14. Two fixing ears 20 are fixed to the top of the base plate 29, and two rotatably mounted between the outer walls of the two fixing ears 20. Rotating shaft 21, three sets of meshing gears 22 are set on the outer wall of two rotating shafts 21, three gears 22 are set on one rotating shaft 21, and the gears 22 on the two rotating shafts 21 mesh in pairs. Second connecting rods 19 are fixed to the outer wall of multiple gears 22. The other end of the second connecting rod 19 is rotatably mounted with a first connecting rod 18 that is rotatably connected to the adjusting plate 14. A connecting shaft 23 is fixed between the outer walls of multiple second connecting rods 19 on the same side. A third connecting rod 24 is rotatably mounted on the outer wall of the connecting shaft 23. Base plate 2 A fixing block 25 is provided on the top of the 9. A first sliding groove 28 is opened on the top of the fixing block 25. A second lead screw 27 is rotatably installed inside the first sliding groove 28. A first slider 26 that is slidably connected to the first sliding groove 28 is threaded onto the outer wall of the second lead screw 27. The top of the first slider 26 is rotatably connected to one end of the third connecting rod 24. A rotating wheel is fixed to one end of both the second lead screw 27 and the first lead screw 17, which makes it easy to rotate the second lead screw 27 and the first lead screw 17 through the rotating wheel, which is quite practical.

[0028] Working principle: The rotation of the first lead screw 17 drives the moving block 16 to move, which in turn drives the electro-autocollimator body 1 to move, facilitating the left and right movement of the electro-autocollimator body 1. When adjusting the height of the electro-autocollimator body 1, the second lead screw 27 is rotated, which drives the first slider 26 to move. The first slider 26 drives the third connecting rod 24 to move, and the third connecting rod 24 drives the second connecting rod 19 on the same side to rotate through the connecting shaft 23. Through the meshing of the gears 22, the second connecting rod 19 on the other side is driven to rotate. The two second connecting rods 19 rotate relative to each other, and the second connecting rod 19 drives the electro-autocollimator body 1 on the adjusting plate 14 to adjust its height, further improving the flexibility of the equipment.
