Description

Technical Field

[0001] The invention relates to the technical field of optical measurement, in particular to an optical measurement positioning device. Background Art

[0002] Industrial automation production involves a variety of inspection and testing, part measurement and identification applications. The most primitive inspection method is manual visual inspection. However, it is usually difficult for the human eye to continuously and stably complete highly repetitive and intelligent tasks. Especially during the inspection process, it is easy to vibrate when holding the camera by hand or placing the camera on the workbench, so the measured workpiece has low accuracy. Using optical measuring devices for measurement can avoid human errors and improve work efficiency.

[0003] According to Chinese patent CN211425476U, an optical measuring device that is easy to use is proposed. The device installs the optical measuring device body in a closed installation box, thereby reducing the influence of dust and moisture on the optical measuring device body, improving the stability and safety of the optical measuring device body during storage, and extending the service life of the optical measuring device body. When in use, the driving component pushes the mounting plate to move to the left, and the mounting plate drives the box door to open synchronously through the resistance component on the optical measuring device body, thereby facilitating the normal use of the optical measuring device body.

[0004] There are some shortcomings in the existing optical measuring devices. In the process of measuring the measured components, it is often necessary to install and position the measured components first to facilitate the operator to measure the measured components. However, due to the diversity of the shapes of the measured components, the existing positioning devices are difficult to stably clamp and fix the measured components with irregular surfaces, which often leads to differences in measurement results and cannot meet the measurement requirements of rapid production. For this reason, we propose an optical measurement and positioning device. Summary of the invention

The outer wall of the plate 3111 is slidably connected, and the top of the L-shaped displacement plate 3111 is fixedly connected to the bottom of the clamping plate 3112. By setting the fixing assembly 31, before the optical measurement of the measured component is required, it must be accurately positioned to improve the stability during the optical measurement. At this time, the operator places the measured component on the top of the carrier 311, and then turns on the first drive motor 318 to drive the first drive motor 318 to rotate with the first output shaft 319, so that the first gear 317 rotates and is connected to the first gear ring 31 6 is meshed, causing the rotating wheel 313 and the rotating rod 312 to rotate. During the rotation of the rotating wheel 313, the arc groove 314 inside it will squeeze the displacement rod 315, causing the bottom of the displacement rod 315 to slide on the bottom of the inner wall of the support platform 311, and bring the L-shaped displacement plate 3111 to slide on the inner wall of the rectangular groove 3110, so that the L-shaped displacement plate 3111 and the clamping plate 3112 are contracted.

[0020] A preferred embodiment of an optical measurement and positioning device provided by the present invention is as follows Figures 1 to 9 As shown: a rotating assembly 32 is also provided on the top of the mounting plate 1, and the rotating assembly 32 includes a fixing frame 321 fixedly connected to the side wall of the mounting plate 1, and the inner wall of the fixing frame 321 is fixedly connected to the second driving motor 322, and the output end of the second driving motor 322 is fixedly connected to the second output shaft 323, and the top outer wall of the second output shaft 323 is fixedly connected to the second gear 324, and the side wall of the second gear 324 is meshed with a second gear ring 325, and the inner wall of the second gear ring 325 is fixedly connected to the outer wall of the bearing platform 311, and the bottom of the bearing platform 311 is fixedly connected to the rotating shaft 326, and the middle outer wall of the rotating shaft 326 is connected to the outer wall of the bearing platform 311. The bearing is rotatably connected to the inner wall of the mounting plate 1. By setting the rotating assembly 32, during the measurement of the measured element, when it is necessary to perform optical measurement on other positions of the measured element, the operator turns on the second drive motor 322 to cause the second output shaft 323 to rotate. During the rotation of the second output shaft 323, the second gear 324 is caused to rotate. During the rotation of the second gear 324, it engages with the second gear ring 325, causing the support platform 311 and the rotating shaft 326 to rotate, thereby facilitating the rotation of the position of the measured element and realizing the measurement of other positions of the measured element.

[0021] A preferred embodiment of an optical measurement and positioning device provided by the present invention is as follows Figures 1 to 9As shown: the top of the mounting plate 1 is fixedly connected with an adjustment component 33, and the adjustment component 33 includes a U-shaped plate 331 fixedly connected to the top of the mounting plate 1, the inner wall of the U-shaped plate 331 is fixedly connected with a forward and reverse motor 332, the output end of the forward and reverse motor 332 is fixedly connected with a screw rod 333, the outer wall of the screw rod 333 is threadedly connected with a sleeve block 334, the outer wall of the sleeve block 334 is fixedly connected with a limit block 335, the side inner wall of the limit block 335 is slidably connected with a limit rod 336, the end face of the limit rod 336 is fixedly connected to the inner wall of the U-shaped plate 331, and the bottom of the sleeve block 334 is fixedly connected with a measuring instrument body 337. By setting the adjustment Component 33, after the positioning of the measured component is completed, the operator opens the measuring instrument body 337 to prompt the measuring instrument body 337 to realize optical measurement of the surface of the measured component. When the measuring position of the measuring instrument body 337 needs to be adjusted, the operator turns on the forward and reverse motor 332 to prompt the screw rod 333 to rotate. During the rotation of the screw rod 333, the sleeve block 334 is limited by the limit block 335 and the limit rod 336, so that when the screw rod 333 rotates, the sleeve block 334 can move laterally on the outer wall of the screw rod 333, thereby facilitating the adjustment of the measuring position of the measuring instrument body 337 and improving the measurement effect.

[0022] Furthermore, a support leg 2 is fixedly connected to the bottom of the mounting plate 1. There are four support legs 2. The four support legs 2 are equal in size and fixedly connected to the four corners of the bottom of the mounting plate 1 at equal distances. By setting four support legs 2, the mounting plate 1 can be supported by the four support legs 2, thereby improving the stability of the mounting plate 1 and improving the stable support effect on the measured component.

[0023] Furthermore, the bottom outer wall of the L-shaped displacement plate 3111 is slidably matched with the inner wall of the rectangular groove 3110 , and the top of the L-shaped displacement plate 3111 is fixedly connected to the bottom of the clamping plate 3112 .

[0024] Furthermore, there are six clamps 3112, and the six clamps 3112 are equal in size. The six clamps 3112 are distributed in a circular array along the central axis of the support platform 311 on the top of the support platform 311. By setting up six clamps 3112, it is convenient to use the six clamps 3112 to achieve stable positioning of the measured component.

[0025] In addition, the inner wall of the arc groove 314 is adapted to the outer wall of the displacement rod 315, and the top of the displacement rod 315 is fixedly connected to the bottom of the L-shaped displacement plate 3111. By setting the displacement rod 315 and the L-shaped displacement plate 3111, it is convenient to move the L-shaped displacement plate 3111 by moving the displacement rod 315.

[0026] Working principle: Before the measured component needs to be optically measured, it must first be accurately positioned to improve its stability during the optical measurement process. At this time, the operator places the measured component on the top of the carrier 311, and then turns on the first drive motor 318 to drive the first drive motor 318 to rotate with the first output shaft 319, so that the first gear 317 rotates and meshes with the first gear ring 316, and the rotating wheel 313 and the rotating rod 312 rotate. During the rotation of the rotating wheel 313, the arc groove 314 inside it squeezes the displacement rod 315, so that the bottom of the displacement rod 315 is on the carrier 311. The inner wall bottom of the L-shaped displacement plate 3111 is slid, and the L-shaped displacement plate 3111 is slid on the inner wall of the rectangular groove 3110, so that the L-shaped displacement plate 3111 is contracted with the clamping plate 3112, and the measured component can be clamped and fixed by the simultaneous contraction of multiple clamping plates 3112, so as to realize the positioning of the measured component. In the process of contraction of the clamping plate 3112, one end of the squeezing rod 3115 will squeeze the surface of the measured component, and the other end of the squeezing rod 3115 will compress the spring 3114. The measured component is squeezed by multiple squeezing rods 3115, so that the clamping plate 3112 can clamp and fix the measured component with an uneven surface. After the positioning of the measured component is completed, the operator opens the measuring instrument body 337 to prompt the measuring instrument body 337 to realize optical measurement of the surface of the measured component. When the measuring position of the measuring instrument body 337 needs to be adjusted, the operator turns on the forward and reverse motor 332 to prompt the screw rod 333 to rotate. During the rotation of the screw rod 333, the sleeve block 334 is limited by the limit block 335 and the limit rod 336, so that when the screw rod 333 rotates, the sleeve block 334 can move laterally on the outer wall of the screw rod 333, thereby facilitating the adjustment of the measuring position of the measuring instrument body 337 and improving the measurement effect. During the measurement of the measured component, when it is necessary to perform optical measurement on other positions of the measured component, the operator turns on the second drive motor 322 to cause the second output shaft 323 to rotate. During the rotation of the second output shaft 323, the second gear 324 is caused to rotate. During the rotation of the second gear 324, it engages with the second ring gear 325, causing the support platform 311 and the rotating shaft 326 to rotate, thereby facilitating the rotation of the position of the measured component and realizing the measurement of other positions of the measured component.
