[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Please see Figure 1-5 This utility model is a multifunctional precision measuring instrument, including a housing 1, a multifunctional detection component 4, and a flipping clamp component 5.

The multifunctional detection component 4 includes a servo motor 41, the bottom of which is fixedly connected to the inner wall of the housing 1. A rotating rod 42 is fixedly connected to the top of the output end of the servo motor 41. The top of the rotating rod 42 passes through the housing 1 and is fixedly connected to a rotating platform 43. A measuring instrument 44 is fixedly connected to the top of the rotating platform 43. A locking mechanism 45 is fixedly connected to the right side of the inner cavity of the housing 1. The flipping clamp component 5 includes a double-ended cylinder 51, the bottom of which is fixedly connected to the housing 1. A mounting frame 52 is fixedly connected to the output ends of the front and rear sides of the double-ended cylinder 51. A rotary motor 53 is fixedly connected to the rear side of the mounting frame 52. A positioning mechanism 54 is provided on the front side of the mounting frame 52. The output ends of the positioning mechanism 54 and the rotary motor 53 on opposite sides pass through the mounting frame 52 and are fixedly connected to a clamping frame 55.

[0027] Specifically: The detection host 2 can store and summarize the data measured by multiple measuring instruments 44. The servo motor 41 is used to control the position of the rotating rod 42 and the rotating table 43. The rotating table 43 can install various measuring instruments 44. Only one fixing of the optical lens is needed to complete multiple detection items. The locking mechanism 45 can lock the rotating rod 42 to prevent the measuring instruments 44 from rotating during measurement operations. The double-ended cylinder 51 is used to control the position of the mounting frame 52 so that it can control the clamping frame 55 to clamp and fix the optical lens. The rotary motor 53 is used to control the orientation of the optical lens so that after completing the measurement work on one side, it automatically flips to the other side for measurement again without the need for the operator to clamp and fix the optical lens again. The positioning mechanism 54 is used to position and fix the optical lens to prevent it from shaking or shifting during the measurement process.

[0028] Example 2

[0029] Please see Figure 1-5 Based on Embodiment 1, the locking mechanism 45 includes a locking toothed plate 451, the right side of which engages with teeth 452 on the surface of the rotating rod 42. A cylinder 453 is fixedly connected to the right side of the inner cavity of the housing 1, and the left side of the output end of the cylinder 453 is fixedly connected to the locking toothed plate 451. The positioning mechanism 54 includes a rotating shaft 541, the rear side of which passes through the mounting frame 52 and is fixedly connected to the clamping frame 55. A friction roller 542 is fixedly connected to the front side of the rotating shaft 541, and an electric push rod 543 is fixedly connected to the front side of the mounting frame 52. A support block 544 is fixedly connected to the top of the output end of the electric actuator 543. A slide rod is fixedly connected to the top of the housing 1. Sliding sleeves are slidably connected to the front and rear sides of the slide rod surface. The left side of the sliding sleeve is fixedly connected to the mounting bracket 52. A positioning sleeve 6 is slidably connected to the surface of the rotating rod 42. The bottom of the positioning sleeve 6 is fixedly connected to the housing 1. Fixing plates are fixedly connected to the bottom of both sides of the housing 1. Fixing openings are provided on the front and rear sides of the bottom of the fixing plates. Operating doors are movably connected to both sides of the front surface of the housing 1 through hinges. A handle is fixedly connected to the front side of the operating door.

[0030] Specifically: Cylinder 453 is used to control the position of locking tooth plate 451. Teeth 452 can mesh with locking tooth plate 451 to prevent rotating rod 42 from rotating and prevent measuring instrument 44 from shaking during the measurement of optical lens. Rotating shaft 541 can facilitate the rotation of clamping frame 55. Electric push rod 543 is used to control the contact between support block 544 and friction roller 542, using friction to prevent rotating shaft 541 and clamping frame 55 from rotating, improving the stability of optical lens clamping, fixing and flipping. Sliding rod and sliding sleeve can limit the two mounting brackets 52, so that they can move back and forth smoothly and avoid them from shifting during the clamping and fixing of optical lens. Positioning sleeve 6 can increase the stability of rotating rod 42 during rotation and prevent it from shaking when controlling the rotation table 43 to rotate, affecting the accuracy of measurement data. Fixing plate and fixing opening can install and fix housing 1 to prevent housing 1 from shifting. Operating door can seal or open housing 1. Handle makes it easy for operator to open operating door.

[0031] The working principle of this utility model is as follows: After placing the lens to be tested between two clamping frames 55, the double-ended cylinder 51 is activated to push the mounting brackets 52 on both sides to move synchronously towards the center along the slide bar, so that the clamping frame 55 contacts the edge of the lens to complete the clamping. The rotary motor 53 drives the clamping frame 55 to rotate through the rotating shaft 541, adjusting the optical lens to the required measurement angle. Then, the electric push rod 543 pushes the support block 544 to press against the friction roller 542, using the friction force of the contact surface to fix the angle of the flipped lens. After clamping is completed, the servo motor 41 drives the rotating rod 42 to drive the rotating table 43 to rotate, and the selected measuring instrument 4... 4. Align the lens with the detection position. At this time, the cylinder 453 pushes the locking tooth plate 451 to engage with the teeth 452 on the surface of the rotating rod 42, keeping the rotating table 43 in a stable position. The detection host 2 simultaneously collects the data parameters of each measuring instrument 44. After the single-sided detection is completed, the locking mechanism 45 is unlocked, and the rotating table 43 switches to the next set of measuring instruments 44 to continue working. When it is necessary to detect the reverse side of the lens, the rotary motor 53 drives the clamping frame 55 to flip the lens again. The entire process only requires one clamping to complete the multi-parameter detection of the lens's double-sided curvature, thickness and refractive index, effectively eliminating the cumulative error caused by traditional step-by-step detection.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
