[0045] The specific arrangement and functions of the adjusting device 6, the supporting device 8 and the auxiliary device 7 are described in detail below.

[0046] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the adjusting device 6 includes a positioning component 61 and a rotating component 62. The positioning component 61 includes a positioning frame 617. The bottom end of the positioning frame 617 is fixedly connected to the surface of the base 5. The upper end surface of the positioning frame 617 abuts against a positioning plate 613. The surface of the positioning plate 613 is fixedly connected with three evenly distributed positioning frames 612. The inner walls of the three positioning frames 612 are all slidably connected with positioning blocks 611. One end of the positioning block 611 is fixedly connected with a first spring 615. The end of the first spring 615 away from the positioning block 611 is fixedly connected to the positioning frame 612. A plurality of positioning grooves 616 are provided on the surface of the positioning block 611. The inner walls of the first spring 615 are all slidably connected with a first telescopic rod 614. The two ends of the first telescopic rod 614 are respectively fixedly connected to the positioning block 611 and the positioning frame 612. The rotating component 62 includes Two rotating grooves 621 are provided on both sides of the surface of the positioning frame 617. The inner walls of the rotating grooves 621 are rotatably connected with rotating rings 622. The upper ends of the rotating rings 622 are fixedly connected with auxiliary gears 625. The inner wall surface of the positioning frame 617 is rotatably connected with a rotating gear 624 at a position corresponding to the auxiliary gear 625. The tooth surface of the rotating gear 624 meshes with the tooth surface of the auxiliary gear 625. The upper end of the rotating gear 624 is fixedly connected to the bottom surface of the positioning plate 613. A plurality of friction grooves 623 are provided on the surface of the rotating ring 622. A connecting groove 63 is provided on the upper end surface of the positioning frame 617. A plurality of balls 64 are rotatably connected to the inner wall of the connecting groove 63. A sliding groove 65 is provided on the bottom surface of the positioning plate 613 at a position corresponding to the ball 64. The inner wall of the sliding groove 65 is slidably connected with the arc surface of the ball 64.

[0047] The effect achieved by the entire adjusting device 6 is that the positioning frame 617 is brought into contact with the positioning plate 613, and then the positioning frame 612 on the positioning plate 613 is used to adjust the position of the positioning block 611 by the tension generated by the first spring 615 in the positioning frame 612, so that the positioning groove 616 on the positioning block 611 is brought into contact with the lens 4 body to fix the position.

The first telescopic rod 614 performs protective limiting. When limiting the entire positioning frame 617 and the lens 4 abutting against the positioning plate 613, in order to facilitate the rotation when measuring and adjusting the lens 4, the rotating rings 622 on both sides of the positioning frame 617 are rotated to allow the auxiliary gear 625 on the rotating ring 622 to mesh and rotate with the rotating gear 624 on the bottom end of the positioning plate 613, thereby rotating and adjusting the position of the entire positioning plate 613 and limiting the position, which is effective and convenient for the deflection operation of the position of the entire lens 4.

[0048] like Figure 7 and Figure 8As shown, the supporting device 8 includes four fixed frames 81, one ends of the four fixed frames 81 are fixedly connected to the bottom surface of the carrying plate 1, the four fixed frames 81 are grouped into two, and the inner walls of each group of fixed frames 81 are rotatably connected with a rotating frame 82 and a rotating frame 83 respectively, the inner walls of both ends of the rotating frame 82 and the rotating frame 83 are fixedly connected with a connecting rod 84, the arc surface of the connecting rod 84 is slidably connected with a sliding column 86, the arc surface of the connecting rod 84 is sleeved with a second spring 85, the two ends of the second spring 85 are fixedly connected to the sliding column 86 and the connecting rod 84 respectively, the arc surfaces of the two sliding columns 86 are rotatably connected with the same second telescopic rod 88, the arc surface of the second telescopic rod 88 is sleeved with a third spring 87, the two ends of the third spring 87 are fixedly connected with the sliding column 86, the bottom surfaces of the rotating frame 82 and the rotating frame 83 are fixedly connected with a plurality of protective pads 89, and the plurality of protective pads 89 are rubber pads.

[0049] The effect achieved by the entire supporting device 8 is that the rotating frame 82 and the rotating frame 83 rotating on the bottom end of the supporting plate 1 are supported, and then the connecting rod 84 on the rotating frame 83 and the rotating frame 82 is used to adjust the position of the sliding column 86 by the tension generated by the second spring 85 on the connecting rod 84, and then the second telescopic rod 88 rotating on the sliding column 86 and the tensile force generated by the third spring 87 are used to limit the position, which effectively and conveniently supports the position of the entire supporting plate 1. When the rotating frame 82 and the rotating frame 83 are used for support and limitation, the protective pad 89 fixed on the bottom surface of the rotating frame 82 and the rotating frame 83 is used to increase the friction, so as to facilitate better support and limit fixation.

[0050] like Fig. 9 As shown, the auxiliary device 7 includes a plurality of connecting plates 71, the bottom surfaces of the plurality of connecting plates 71 are fixedly connected to the surface of the supporting plate 1, the two side surfaces of the connecting plates 71 are fixedly connected to fixed frames 72, the surfaces of the fixed frames 72 are rotatably connected to rotating shafts 75, the arc surfaces of the rotating shafts 75 are rotatably connected to connecting frames 73, the inner walls of the connecting frames 73 are in contact with the lenses 4, and the surfaces of the connecting plates 71 are fixedly connected to support pads 74 at positions corresponding to the lenses 4, the cross-section of the support pads 74 is arc-shaped, and the surface of the support pads 74 is in contact with the surface of the lenses 4.

[0051] The effect achieved by the entire auxiliary device 7 is that the rotating shaft 75 on the fixed frame 72 drives the connecting frame 73 to abut and fix the lens 4, thereby effectively and conveniently placing and fixing the lens 4. In the process of abutting and limiting the lens 4, in order to avoid bumping against the lens 4, the support pad 74 fixed on the connecting plate 71 is used for protective limiting.

[0052] Example 2, based on Example 1,

[0053] The overall working principle is that when the optical lens 4 is measured using an eccentric meter, it is usually necessary to fix and limit the optical lens 4. Since there are many types of optical lenses 4 and the fixed dimensions of the optical lenses 4 on the entire operating table are relatively uniform, it is inconvenient to replace and limit various types of optical lenses 4. At this time, the positioning component 61 and the rotating component 62 on the adjusting device 6 are used to fix and limit the optical lens 4 on the entire supporting plate 1.

[0054] When measuring the eccentricity of aspheric optical parts, in order to conveniently and quickly abut and fix a variety of optical lenses 4, the positioning frame 617 fixed on the base 5 is used to abut the positioning frame 617 with the positioning plate 613, and then the positioning frame 612 on the positioning plate 613 is used to adjust the position of the positioning block 611 by the tension generated by the first spring 615 in the positioning frame 612, so that the positioning groove 616 opened on the positioning block 611 abuts and fixes the lens 4 body. When the first spring 615 is operated and used, in order to avoid deformation of the first spring 615, the first telescopic rod 614 in the first spring 615 is used for protection and limitation. 7 When limiting the position of the lens 4 abutting against the positioning plate 613, in order to facilitate the rotation when measuring and adjusting the lens 4, the rotating rings 622 on both sides of the positioning frame 617 are rotated, so that the auxiliary gear 625 on the rotating ring 622 and the rotating gear 624 on the bottom end of the positioning plate 613 are meshed and rotated, thereby rotating and adjusting the position of the entire positioning plate 613 to limit the position, effectively facilitating the deflection operation of the position of the entire lens 4. When the positioning plate 613 on the positioning frame 617 is adjusted and rotated, the rotating ball 64 on the positioning frame 617 and the sliding groove 65 on the positioning plate 613 can effectively reduce friction, so as to facilitate better use and operation of the positioning plate 613.

[0055] When the eccentricity measuring device of the entire aspheric optical part is used, in order to better support and limit the support plate 1 and the microscope 3, the support is provided by the rotating frame 82 and the rotating frame 83 rotating on the bottom end of the support plate 1, and then the connecting rod 84 on the rotating frame 83 and the rotating frame 82 is used to adjust the position of the sliding column 86 by the tension generated by the second spring 85 on the connecting rod 84, and then the tension generated by the second telescopic rod 88 and the third spring 87 rotating on the sliding column 86 is used to limit the position, which effectively and conveniently supports the position of the entire support plate 1. When the rotating frame 82 and the rotating frame 83 are used for support and limitation, the protective pad 89 fixed on the bottom surface of the rotating frame 82 and the rotating frame 83 is used to increase the friction, so as to facilitate better support and limitation.

[0056] When abutting and limiting a plurality of different types of optical lenses 4, they are fixed by the connecting plate 71 fixed on the supporting plate 1, and then the upper limit fixing frame 72 on the connecting plate 71 is used, so that the rotating shaft 75 on the fixing frame 72 drives the connecting frame 73 to abut and fix the lenses 4, thereby effectively and conveniently placing and fixing the lenses 4. In the process of abutting and limiting the lenses 4, in order to avoid bumping against the lenses 4, the support pads 74 fixed on the connecting plate 71 are used for protective limiting.
