[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1, such as Figures 1-4The present invention provides the following technical solution to address the problems of inconvenient and unstable product clamping by the measuring device: A pressing mechanism is disclosed, comprising a base 1, a support rod 2 connected to the top of the base 1, and a CV-X vision sensor 3 mounted on the side of the support rod 2. A connecting seat 101 is connected to the top of the base 1 away from the support rod 2, and an external block 102 is connected to the side of the connecting seat 101. A movable groove 103 is formed on the side of the external block 102 away from the connecting seat 101, and the movable groove 103 contains a pressing mechanism to improve the efficiency of the device's clamping adjustment arm. The pressing mechanism includes a driven wheel 104, which rotates inside the movable groove 103 via a bearing. A rotating block 105 is fixed to the side of the driven wheel 104. A guide rod 106 slides symmetrically through the movable groove 103. A rotating rod 107 is rotatably connected between the guide rod 106 and the rotating block 105. A clamping block 108 is fixed to the side of the guide rod 106. A sliding groove 109 is opened on the side of the outer block 102 near the movable groove 103. A dual-head motor 110 is connected inside the sliding groove 109. A first drive wheel 111 is connected to one output end of the dual-head motor 110.

[0029] When using the measuring device, first place the adjusting arm on the upper surface of the base 1, and then measure the aperture or length of the adjusting arm using the CV-X vision sensor 3. The CV-X vision sensor 3 works in conjunction with a high-precision optical system and intelligent algorithms to achieve fast, non-contact measurement of the adjusting arm. A high-pixel camera paired with a ring LED light source eliminates interference from metal surface reflections and clearly captures the contour, aperture, and other features of the adjusting arm. Before measurement, the device is placed between the clamping blocks 108, and then the dual-head motor 110 is started. The output of the dual-head motor 110 can drive the first drive wheel 111 to rotate. When the first drive wheel 111 rotates, it can drive the driven wheel 104 to mesh and rotate. When the driven wheel 104 rotates in mesh, it can rotate through the bearing. When the driven wheel 104 rotates, it can drive the rotating block 105 to rotate. When the rotating block 105 rotates, it can drive the rotating rod 107 to move. When the rotating rod 107 moves, it can pull the guide rod 106 to move. When the guide rod 106 moves, it can slide through the movable groove 103. At the same time, when the rotating rod 107 moves, it can rotate through the guide rod 106 and the rotating block 105. When the guide rod 106 slides, it can drive the clamping block 108 to slide to the side of the adjusting arm for compression and fixation. After the adjusting arm is fixed, the shaking caused by external interference is reduced. Moreover, due to the finer gear meshing, the accuracy of the adjusting arm measurement is improved.

[0030] Example 2, as follows Figure 2 , Figure 5 and Figure 6The present invention provides the following technical solution to address the problem of insufficient accuracy in measurement due to the single recognition angle of the CV-X vision sensor 3 in the measuring device. Based on Embodiment 1, a rotating mechanism is disclosed: an annular groove 112 is provided through the side of the external block 102 near the connecting seat 101. A rotating mechanism for changing the angle of the adjusting arm is provided on the side of the external block 102. The rotating mechanism includes an annular block 113, which is fixed to the side of the connecting seat 101 and rotates through the annular groove 112. A rotating groove 114 is provided on the side of 101. A fixed column 115 is fixedly connected inside the rotating groove 114. A fixed tooth 116 is fixed on the surface of the fixed column 115. A second drive wheel 119 is meshed with the side of the fixed tooth 116. The second drive wheel 119 is fixed to the output end of the dual-head motor 110 on the other side. A sliding block 117 slides inside the sliding groove 109. A dual-head motor 110 is installed on the top of the sliding block 117. An electric push rod 118 is connected to the side of the sliding block 117 away from the dual-head motor 110. The electric push rod 118 is installed inside the sliding groove 109.

[0031] After the measuring device fixes the adjusting arm, it starts the electric actuator 118. When the electric actuator 118 starts, its output end can push the sliding block 117 to move. When the sliding block 117 moves, it can slide through the sliding groove 109. When the sliding block 117 slides, it can drive the dual-head motor 110 to move. When the dual-head motor 110 moves, it can drive the first drive wheel 111 and the second drive wheel 119 to move. When the second drive wheel 119 moves to the meshing side of the fixed tooth 116, the first drive wheel 111 will move out of the side of the driven wheel 104. At this time, restarting the output end of the dual-head motor 110 can drive the second drive wheel 119 to rotate. When the driving wheel 119 rotates, it can rotate through the meshing of the fixed tooth 116. When the second driving wheel 119 rotates, the outer block 102 can rotate. When the outer block 102 rotates, it can drive the annular groove 112 to rotate. When the annular groove 112 rotates, it can rotate through the annular block 113. At the same time, the second driving wheel 119 can rotate around the fixed tooth 116 inside the rotating groove 114. When the outer block 102 rotates, it can drive the clamped adjustment arm to adjust its direction, so that the CV-X vision sensor 3 can measure and identify the adjustment arm from more directions, thus improving the accuracy of the CV-X vision sensor 3 in identifying and measuring the adjustment arm.

[0032] As a preferred embodiment, the use of the CV-X vision sensor 3 for measuring parameters is a conventional technique for those skilled in the art, and its principles and logic are also recorded in existing technical solution manuals, so its principles and structure will not be discussed in detail here.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
