Description

Technical Field

[0003] At present, in the process of using the autocollimator for laser alignment, it is necessary to first fix the reflector to the bridge plate, so that the center of the host objective lens and the reflector lens are basically in a straight line, straighten the reflector, move the reflector to the far end of the host, and move the short guide rail directly to the tail end. For the long guide rail, it can be moved to a position 3-5 meters away from the host. Then stand behind the host and observe whether the image of the guide rail in the reflector is parallel to the actual guide rail. If not, it is necessary to fine-tune the deflection angle of the reflector. After the two are parallel, lock the reflector and the base below, and the host is zeroed.

[0035] Refer to Figure 1 , Figure 4 and Figure 5The lower right end of the connecting rod 811 is fixedly connected to the top of the second chain 89, the inner wall of the slide plate 86 passes through and is rotatably connected with a rotating rod 814, the left end of the rotating rod 814 is fixedly connected to the right end of the sprocket wheel three 87, the outer wall of the rotating rod 814 is fixedly connected with the second gear 815, the rear end of the slide plate 86 is rotatably connected with a rotating wheel 816, the rear end of the rotating wheel 816 is provided with a spiral protrusion, the number of circles of the spiral protrusion at the rear end of the rotating wheel 816 is slightly greater than one circle, the pitch of the spiral protrusion at the rear end of the rotating wheel 816 is matched with the spacing between two adjacent teeth of the second gear 815, and the shape of the protrusion at the rear end of the rotating wheel 816 is The shape of the setting ensures that when the wheel 816 rotates one circle, it can drive the gear 2 815 to rotate one tooth pitch, so as to achieve the effect of more accurately controlling the rotation angle of the reflector 7. The shaft of the wheel 816 passes through the inner wall of the slide plate 86 and is fixedly connected with a knob 817. The front surface of the knob 817 is provided with a triangular arrow. The front surface of the slide plate 86 outside the knob 817 is provided with scale lines. The setting of the arrow and the scale lines ensures that the staff can rotate the knob 817 more accurately to control the rotation angle of the reflector 7. The knob 817 is at the front end of the slide plate 86.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The sprocket 81 and the sprocket three 87 are fixed by a connecting assembly 9, which includes a connecting disk 91. The diameter of the connecting disk 91 is larger than the outer diameter of the sprocket 81. The connecting disk 91 is fixedly connected to the right end of the sprocket 81, and the left end of the sprocket three 87 is fixedly connected to a connecting disk 2 92. The models of the connecting disk 91 and the connecting disk 2 92 are consistent, and the connecting disk 91 and the connecting disk 2 92 are mirror-imaged. The outer wall of the connecting disk 91 is fixedly connected to a fixing frame 93, and a threaded rod 94 is penetrated through and threadedly connected to the inner wall of the right end of the fixing frame 93, and the left end of the threaded rod 94 is fixedly connected to a fixing plate 95, and an anti-slip pad is provided at the left end of the fixing plate 95.

[0037] Working principle: When in use, the staff first rotates the threaded rod 94 when aligning, so that the threaded rod 94 drives the fixed plate 95 to move to the left, so that the fixed plate 95 moves to the left until it contacts the second connecting plate 92, and then drives the second connecting plate 92 to move to the left together, until the second connecting plate 92 fits with the first connecting plate 91, at which time the second connecting plate 92 is fixed to the first connecting plate 91.

[0038] At this time, the staff rotates the rotating rod 814, so that the rotating rod 814 drives the sprocket three 87 to rotate, so that the sprocket three 87 drives the sprocket four 88 to rotate under the transmission action of the chain two 89. At the same time, since the sprocket three 87 and the sprocket one 81 are relatively fixed, the sprocket one 81 rotates with the sprocket three 87. Therefore, in the process of rotation, the sprocket one 81 drives the chain one 83 with the cooperation of the sprocket two 82, thereby driving the moving block 85 to move backward, so that the moving block 85 drives the base 5 and the reflector 7 to move backward, so as to achieve the effect of adjusting the distance between the reflector 7 and the main machine 3.

[0039] When the reflector 7 moves to a suitable distance, the staff member rotates the threaded rod 94 in the opposite direction, thereby driving the fixing plate 95 to move to the right. At this time, the staff member manually pushes the slide plate 86 to the right, thereby separating the connecting disk 1 91 from the connecting disk 2 92. At this time, the staff member turns the knob 817 while observing the horizontal state of the mounting plate 2 in the reflector 7, thereby causing the knob 817 to drive the rotating wheel 816 to rotate, thereby causing the rotating wheel 816 to drive the gear 2 815 to rotate.

[0040] When gear two 815 rotates, gear two 815 drives the rotating rod 814 to rotate, thereby causing sprocket three 87 to rotate, and sprocket three 87 drives chain two 89 with the cooperation of sprocket four 88, thereby driving connecting rod 811 to move forward and backward, thereby causing rack 812 to move forward and backward, thereby causing gear one 813 to rotate and drive the reflector 7 to rotate, and during the rotation process, the staff can accurately adjust the rotation amplitude of knob 817 through the corresponding positions of the arrow on knob 817 and the scale line, thereby ensuring the accuracy of adjustment of reflector 7.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
