A rectangular shell 99 is placed on the top of the support plate 91. The two groups of fixing plates 98 are used to fix the rectangular shell 99. The micrometer 10 is placed inside the rectangular shell 99. An opening is opened on the surface of the rectangular shell 99.

[0027] An extension plate 11 is provided at the top of the rectangular shell 99, and a camera 12 is fixedly installed on one side of the extension plate 11 close to the micrometer 10. The camera 12 is used to record the measurement data of the micrometer 10 to facilitate subsequent data analysis and processing.

[0028] Specifically, when in use, the staff first places the dial gauge 10 inside the rectangular shell 99, and the detection head of the dial gauge 10 passes through the opening formed on the surface of the rectangular shell 99, and then fixes the rectangular shell 99 on the support plate 91. At this time, the pressure plate 93 provided on the top of the rack four 94 passes through the notch 92 and protrudes from the surface of the support plate 91, so that the rectangular shell 99 presses the pressure plate 93 downward, and the pressure plate 93 presses the rack four 94 downward, and the rack four 94 slides downward in the notch 92, and the rack four 94 compresses and stores force on the compression spring 910, and the rack four 94 meshes with the gear three 95, and the gear three 95 drives the screw 96 to rotate, and the two ends of the screw 96 are rotatably connected with the notch 92, and the screw 9 The surface of the gear 6 is symmetrically distributed with reverse threads about the gear three 95, and the surface of the screw 96 is threadedly connected with two groups of movable blocks 97, which move in opposite directions.

The camera 12 records the measurement data of the micrometer 10, which is convenient for subsequent data analysis and processing, and reduces the shaking of the micrometer 10 during the measurement process, thereby improving the accuracy and reliability of the measurement; Secondly, the frame 1 is fixed to the workbench 3 with bolts through multiple sets of fixed protective plates 2. The operator places the single board 4 in the middle of the workbench 3 and starts the motor 51 embedded in the workbench 3. A groove 59 is opened on the surface of the workbench 3, and the motor 51 is fixedly installed inside the groove 59. The motor 51 drives the gear 1 52 at the output end to rotate. Since the rack 1 53 and the rack 2 55 and the rack 3 57 are staggered up and down, the gear 1 52 is meshed with the rack 1 53, the rack 2 55 and the rack 3 57, and the rack 1 53, the rack 2 55 and the rack 3 57 are all slidably connected with the groove 59. The rack 2 55 and the rack 3 57 move in opposite directions. 53, rack 2 55 and rack 3 57 drive the clamping plate 1 54, clamping plate 2 56 and clamping plate 3 58 set at each end to approach and clamp the single board 4, so that the three sides of the single board 4 are clamped, and only the side close to the dial gauge 10 is left to be measured. The single board 4 only leaves the side close to the dial gauge 10 to be measured, accurately determines the measurement position, avoids interference from other sides, makes the measurement more accurate and targeted, and the clamping plate 1 54, clamping plate 2 56 and clamping plate 3 58 fit the contact surface of the single board 4, so that the single board 4 is more stable during the measurement process, ensuring that the single board 4 is fixed in position during the measurement process, and will not move or shake, which is conducive to improving the measurement accuracy; Then the operator drives the servo motor 62 fixed on one side of the workbench 3 through the carrier plate 61 to drive the screw 63 to rotate. The servo motor 62 rotates slowly. The surface of the screw 63 is threadedly connected with a moving block 64. The moving block 64 is slidably connected to the workbench 3, so that the moving block 64 drives the vertical plate 74 on one side of the frame plate 81 to move. One side of the vertical plate 74 is rotated and connected with the gear 2 72. As the moving block 64 moves, the gear 2 72 is meshed with the long rack 71 correspondingly arranged on the surface of the workbench 3. The long rack 71 is equal in length to the measuring surface of the single plate 4. Tooth blocks are evenly distributed on the surface of the long rack 71. There are 12 groups of tooth blocks. A group of tooth blocks close to the servo motor 62 has 9 teeth, and the remaining eleven groups of tooth blocks have 6 teeth each. However, the teeth of two adjacent groups of tooth blocks are There is a spacing between the tooth blocks, so that when the gear 2 72 and the long rack 71 are meshed with a group of teeth close to the servo motor 62 and rotate three quarters of a circle, the gear 2 72 drives the rotating rod 73 to rotate three quarters of a circle, and the rotating rod 73 drives the transmission belt 75 to drive the driven rod 83 to rotate, the driven rod 83 is rotationally connected with the sleeve block 82, the sleeve block 82 is fixedly connected with the frame plate 81, and the driven rod 83 drives the rotating block 84 at one end to rotate three quarters of a circle, so that the rotating block 84 drives the swing rod 85 to rotate three quarters of a circle, the rotating block 84 is rotating but sliding on the surface of the swing rod 85, the rotating block 84 compresses and stretches the spring 86, so that the swing rod 85 drives the connecting seat 87 at one end to rotate, and the connecting seat 87 is rotationally connected with the rotating shaft 88 Then, the rotating shaft 88 is fixedly connected to the moving plate 89. When the driven rod 83 drives the swing rod 85 to rotate a quarter of a circle, since the micrometer 10 and the camera 12 are fixed to one side of the moving plate 89 through the fixed structure 9, the moving plate 89 drives the micrometer 10 and the camera 12 to slide from the bottom end of the vertical slide bar 810 to the top end, and the angle of the measuring surface of the single board 4 is measured from bottom to bottom, and the length of the straight path is equal to the thickness of the single board 4, so that the micrometer 10 can measure the angle of the single board 4, and the camera 12 records it. When the driven rod 83 continues to drive the swing rod 85 to rotate to half a circle, the moving plate 89 drives the micrometer 10 and the camera 12 to slide from the bottom end of the vertical slide bar 810 to the top end of the horizontal slide bar 811 through the sliding sleeve 812 at the top end of the vertical slide bar 810. One end close to the servo motor 62 slides to the other end, which is to measure the angle of the measuring surface of the single board 4 from left to right in the horizontal path. When the driven rod 83 continues to drive the swing rod 85 to rotate to three-quarters of a circle, the moving plate 89 drives the micrometer 10 and the camera 12 to slide from the top of the vertical slide rod 810 to the bottom, and the angle of the measuring surface of the single board 4 is measured from top to bottom, so that the first group of gear blocks of the gear 2 72 and the long rack 71 are arranged and driven to complete, thereby completing the angle measurement of the three surfaces connected by the four points on the surface of the single board 4, and completing the fixed-point equidistant angle measurement work, so that the measurement results are more regular and comparable, and the integrity and accuracy of the measurement are improved, which is convenient for accurate evaluation of the quality of the single board 4; Then, after the gear 2 72 is disengaged from the drive of a set of teeth near the servo motor 62, as the moving block 64 continues to move, the gear 2 72 enters the gap between a set of teeth near the servo motor 62 and another set of teeth, and the gap length is equal to the length of the short rack 78. At this time, the hydraulic rod 77 fixed to the connecting plate 76 on one side of the frame plate 81 drives the short rack 78 at the output end to move in the opposite direction and mesh with the gear 2 72. Since there are 6 teeth distributed on the surface of the short rack 78, when the short rack 78 meshes with the gear 2 72 and rotates in the opposite direction for a quarter of a turn, the moving plate 81 9 drives the dial gauge 10 and the camera 12 to slide from the bottom end of the vertical slide bar 810 to the top end, and measures the angle of the measuring surface of the single board 4 from bottom to top. When the short rack 78 and the gear 2 72 are meshed and rotated in the opposite direction to half a circle, the moving plate 89 drives the dial gauge 10 and the camera 12 to slide from one end of the horizontal slide bar 811 away from the servo motor 62 to the other end, and measures the angle of the measuring surface of the single board 4 from the horizontal path. Then, as the moving block 64 continues to move, the gear 2 72 is meshed with the remaining gear blocks on the surface of the long rack 71, so that the moving plate 8 9 drives the dial gauge 10 and the camera 12 to slide from the sliding sleeve 812 at the top of the vertical slide bar 810 to the other end of the horizontal slide bar 811 from one end close to the servo motor 62, which is to measure the angle of the single board 4 measuring surface from left to right in the horizontal path. When the driven rod 83 continues to drive the swing rod 85 to rotate to three-quarters of a circle, the moving plate 89 drives the dial gauge 10 and the camera 12 to slide from the top of the vertical slide bar 810 to the bottom, and the angle of the single board 4 measuring surface from top to bottom is measured. As the moving block 64 continues to move, it will drive the gear 2 72 and the other gears to rotate. The meshing rotation is one quarter to one half of a circle, and each time the gear 2 72 rotates to the spacing between the two adjacent sets of gear blocks, the short rack 78 is driven to move and mesh with the gear 2 72 in the opposite direction. Similar to the above description, no repeated description is given here. With the continuous movement of the moving block 64, the measurement surface of the single board 4 can be continuously and uninterruptedly measured from one end close to the servo motor 62 to the other end at fixed points and at equal distances. There is no need to frequently adjust the equipment or reposition the single board 4, which greatly improves the measurement efficiency and is suitable for single board 4 measurement in large-scale production.
