[0034] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0035] like Figure 1 and Figure 2 As shown, a 180-degree XY virtual position distance detection device of this embodiment includes a lifting platform 13, on which a product assembly 5 is placed, the product assembly 5 includes a plate group 1 51 and a plate group 2 52 which are rotatably connected at the edges, the plate group 1 51 and the plate group 2 52 are unfolded 180° and placed horizontally on the lifting platform 13, and the plate group 1 51 is fixed and pressed on the lifting platform 13; it also includes an X-direction force applying mechanism 4 and a Y-direction force applying mechanism 6, the X-direction force applying mechanism 4 applies an X-direction thrust to the plate group 2 52 via the X-direction push arm 45, and the Y-direction force applying mechanism 6 applies a Y-direction thrust to the plate group 2 52 via the Y-direction push arm 64.

[0036] During detection, a constant thrust is applied to the plate group 2 52 in the positive and negative X direction and the positive and negative Y direction respectively via the X-direction push arm 45 and the Y-direction push arm 64. The displacement detector is combined to detect the displacement of the plate group 2 52 in the X direction and the Y direction before and after the force is applied, and the virtual position distance in the unfolded state is obtained.

[0037] The edges of the plate group 1 51 and the plate group 2 52 are connected via hinges or rotating shafts to form a rotating connection structure, and the axial direction of the rotating connection structure is arranged along the X direction.

[0038] During the test, the plate group 1 51 is fixedly clamped relative to the lifting platform 13, and force is applied to the plate group 2 52. The displacement value of the plate group 2 52 before and after is detected to obtain the virtual distance detection of the rotating connection structure, thereby effectively evaluating the stability and reliability of the rotating connection structure under the stress state.

[0039] like Figure 3 As shown, a plurality of positioning cone pins 10 are convexly provided on the top surface of the lifting platform 13 , and holes corresponding to the positioning cone pins 10 are opened on the plate group 1 51 , thereby achieving the initial positioning of the plate group 1 51 on the lifting platform 13 .

[0040] A horizontal clamping mechanism 3 is installed on the lifting platform 13 located on both sides of the plate group 51, and also includes a vertical clamping mechanism 9. The horizontal clamping mechanism 3 presses the plate group 51 from the horizontal direction, and the vertical clamping mechanism 9 presses the plate group 51 from top to bottom, thereby achieving reliable fixed clamping of the plate group 51 on the lifting platform 13.

[0041] The structure of the horizontal clamping mechanism 3 is as follows: it includes a fixed block 30 and an insert block 31 located on both sides of the opposite sides of the plate group 51, and the edge of the plate group 51 is provided with a V-shaped groove 511 matched with the fixed block 30 and the insert block 31; the fixed block 30 is fixed on the lifting platform 13, and the insert block 31 is installed at the output end of the horizontal clamping mechanism 3, and the insert block 31 is driven by the horizontal clamping mechanism 3 to move toward or away from the fixed block 30.

[0042] In this embodiment, the axial direction of the rotating connection structure between plate group 1 51 and plate group 2 52 is arranged along the X direction, and the fixed block 30 and the plug-in block 31 are located on both sides of the plate group 1 51 in the X direction and are arranged toward the plate group 1 51 along the X direction; during operation, the plate group 1 51 is placed between the fixed block 30 and the plug-in block 31, and the horizontal clamping mechanism 3 works to push the plug-in block 31 toward the plate group 1 51 until the plug-in block 31 is inserted into the V-groove 511, and combined with the fixed block 30, the plate group 1 51 is clamped and fixed in the horizontal direction.

[0043] In this embodiment, both sides of the plate group 1 51 are assembled with the V-shaped protrusions of the fixing block 30 and the inserting block 31 via the V-shaped grooves 511, so as to realize the clamping in the X direction and ensure the positioning and clamping in the Y direction.

[0044] The vertical clamping mechanism 9 includes a rotary downward pressing cylinder installed on the lifting platform 13, and a pressing block 91 is installed at the output end of the rotary downward pressing cylinder. The pressing block 91 is pressed above the plate group 51, thereby effectively ensuring the fixation and limitation of the plate group 51 in the height direction.

[0045] In actual operation, the vertical clamping mechanism 9 mainly limits the plate group 51 in the vertical direction to prevent it from tilting upward when clamped by the horizontal clamping mechanism 3. A preset limiting gap can be left between the bottom end of the clamping block 91 of the vertical clamping mechanism 9 and the top surface of the plate group 51, which does not affect the movement of the plate group 51 in the horizontal plane when the horizontal clamping mechanism 3 is actuated.

[0046] A pressure protection mechanism 8 is installed on the lifting platform 13 located on the lateral outside of the second plate group 52. The pressure protection mechanism 8 includes a linear sliding module installed on the lifting platform 13. A pressure protection block 81 is installed at the output end of the linear sliding module. The linear sliding module drives the pressure protection block 81 to move above the second plate group 52.

[0047] In this embodiment, through the setting of the pressure protection mechanism 8, during testing, the linear sliding module drives the pressure protection block 81 to move to the top of the plate group 2 52 for limiting and pressure protection. When the plate group 2 52 is subjected to the test force in the X and Y directions, the pressure protection block 81 prevents the plate group 2 52 from warping up due to the force.

[0048] The X-direction force applying mechanism 4 and the Y-direction force applying mechanism 6 are installed below the lifting platform 13. The X-direction force applying mechanism 4 and the Y-direction force applying mechanism 6 include a moving module arranged along the X-direction or the Y-direction. A moving block is installed at the output end of the moving module. The moving block is connected to a push arm via a force sensor. The push arm passes upward through the lifting platform 13. The push arm is an X-direction push arm 45 or a Y-direction push arm 64. The X-direction push arm 45 includes two relatively fixed and spaced apart push arms. The two X-direction push arms 45 are located on the outer sides of the opposite sides of the second plate group 52, and the Y-direction push arm 64 is located at the hollowed-out middle part of the second plate group 52.

[0050] In this embodiment, the spacing distance between the two X-direction pushing arms 45 is greater than the width distance between two opposite edges of the second plate group 52 in the X-direction.

[0051] During the test, the X-direction moving module 41 works, and the X-direction push arms 45 are driven to move in the positive and negative directions of the X-direction through the support plate 44. The two X-direction push arms 45 contact and apply force to the corresponding edges of the plate group 2 52 in turn, thereby completing the application of force to the plate group 2 52 in the positive and negative directions of the X-direction, and the X-direction force sensor 43 monitors and feeds back the force value in real time.

[0052] exist Figure 5 In the illustrated embodiment, the structure of the Y-direction force-applying mechanism 6 is as follows: it includes a Y-direction movable module 61 installed on the lower suspension platform 12, a Y-direction movable block 62 is installed at the output end of the Y-direction movable module 61, the Y-direction movable block 62 is connected to a Y-direction push arm 64 via a Y-direction force sensor 63, and the Y-direction push arm 64 passes upward through the upper lifting platform 13.

[0053] In this embodiment, a hollow space with a rectangular structure that runs through from top to bottom is opened in the middle of the second plate group 52, and the Y-direction push arm 64 extends upward into the hollow space.

[0054] During the test, the Y-direction moving module 61 works, driving the Y-direction push arm 64 to move in the positive and negative directions of the Y direction respectively, and to contact and apply force to the inner wall surfaces of the rectangular structure hollow opposite to each other in the Y direction, thereby completing the application of force to the plate group 2 52 in the positive and negative directions of the Y direction, and the Y-direction force sensor 63 monitors and feeds back the force value in real time.

[0055] It also includes an X-direction displacement detector 2 and a Y-direction displacement detector 7. The X-direction displacement detector 2 is arranged horizontally along the X direction toward the plate group 2 52, and the Y-direction displacement detector 7 is arranged horizontally along the Y direction toward the plate group 2 52, so that the X-direction displacement detector 2 and the Y-direction displacement detector 7 respectively detect the displacement values ​​of the plate group 2 52 in the X direction and the Y direction before and after the feedback force is applied.

[0056] In this embodiment, the X-axis displacement detector 2 and the Y-axis displacement detector 7 may be laser displacement sensors or visual cameras, as long as they can effectively and stably feedback the displacement values ​​before and after the force is applied.

[0057] In this embodiment, sunken steps 131 are respectively provided at adjacent edges of the lifting platform 13 for installing the X-axis displacement detector 2 and the Y-axis displacement detector 7, and are convenient for position adjustment along the sunken steps 131 to effectively ensure the detection of the second plate group 52.

[0059] In this embodiment, an upper lifting platform 13 and a lower hanging platform 12 are installed above and below the working platform 1, respectively, to facilitate the arrangement of the X-direction force applying mechanism 4 and the Y-direction force applying mechanism 6 relative to the product component 5, and effectively realize and ensure the virtual distance detection of the product component 5 in the XY direction.

[0060] In actual testing, the loading and unloading of product components 5 is performed manually, the equipment automatically applies thrust detection, and the tested products are manually picked up. Red and green indicator lights can be set on the equipment, and a preset value matching the detection displacement value is set. The preset value is compared with the detection value. When the detection value is greater than the preset value, the red light is on, indicating a bad detection, and when the detection value is less than or equal to the preset value, the green light is on, indicating a passed detection, so that manual judgment of the shaft inspection result is better and faster.

[0061] The detection device of the utility model has a fast production test cycle, and uses a laser displacement sensor to detect the displacement. The motion components all use a screw module to control the motion, with high precision and good stability. The sensor accuracy of the measured force value is ±0.3% FS, and the test data preparation is reliable.

[0062] The 180-degree XY virtual distance detection device in the utility model can be used in the product development and testing stages. Through the virtual distance detection, the deviation between the test displacement and the design value can be intuitively obtained, which is convenient for the improvement and enhancement of the design structure. It can also be used in the quality inspection process after the assembly of the rotating shaft hinge in actual production.
