DETAILED DESCRIPTION
[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.
[0028] See also Figures 1 to 7The present invention provides the following technical solutions: a precise measuring device for office desk production dimensions, comprising a measuring device body, the measuring device body comprising a bottom measuring frame 1, a top measuring frame 2, a thickness detection component 3 and a width detection component 4, the top of the bottom measuring frame 1 is welded with a support shaft 24, the top of the top measuring frame 2 is welded with a rotating arm 5, and one end of the rotating arm 5 is provided with a rotating ring 9, the rotating arm 5 is sleeved on the support shaft 24 through the rotating ring 9, the number of the top measuring frames 2 is two, the end of one of the top measuring frames 2 is welded with a width detection component 4, the bottom of the width detection component 4 is embedded with a first ball 18, the first ball 18 is used to lean against the edge of the office desk to be measured, the bottom end of the bottom measuring frame 1 is welded with a support plate 27, the end of the support plate 27 is welded with a threaded sleeve 28, the thickness detection component 3 is embedded in the inside of the threaded sleeve 28, and the top of the thickness detection component 3 is embedded with a second ball 31, the second ball 31 is used to lean against the bottom of the table board of the office desk to be measured. The office desk production dimension precision measuring device is used to measure the thickness, width and surface flatness of the desk surface part.
[0029] When the present invention is used, the bottom measuring frame 1 is pressed against one side of the desk board to be measured when the top measuring frame 2 is in the unfolded state, and the thickness detection component 3 is pressed against the bottom of the desk board to be measured, and then the top measuring frame 2 is rotated until the top measuring frame 2 is rotated to the surface of the desk board to be measured and docked with each other, and the docking process of the two top measuring frames 1 is completed with the help of the magnetic suction plates 11 on the two docking plates 8, and the two conductive contact sheets 12 are also contacted to achieve the effect of circuit connection, and finally the first ball 18 in the end width detection component 4 is pulled until the first ball 18 is pressed against the desk board to be measured. When measuring, directly pull the pull rod 13 to control the entire measuring device to move along the surface of the office desk to be tested, and obtain the pressure changes of the first pressure module 16 and the second pressure module 34 during the detection process. When the pressure change value detected by the second pressure module 34 in the thickness detection component 3 is large, it can be determined that the thickness of the current detection area has changed. Similarly, when the pressure value in the width detection component 4 area changes, it can be determined that there is a difference in the width of the office desk to be tested in the current area. After completing the detection, directly pull the pull rods 13 on the two top-level detection frames to unfold them and remove them.
[0030] In this embodiment, the top-level measurement frame 2 includes a rotating arm 5 and a docking plate 8. The bottom of the rotating arm 5 is integrally formed with a lower hanging plate 6. A slot 14 is provided on the inner side of the lower hanging plate 6. A pressing guide roller 7 is embedded in the slot 14. The side of the rotating arm 5 is integrally formed with an extension rod 10. The docking plate 8 is integrally formed at the end of the extension rod 10. A magnetic plate 11 and a conductive contact sheet 12 are embedded on the surface of the docking plate 8. A pull rod 13 is welded on the top of the docking plate 8. Each of the pressing guide rollers 7 is used to press on the surface of the desk to be tested. The two docking plates 8 are mutually adsorbed and attached through the magnetic plates 11 embedded on the inner side. After completing the inspection process of the desk, the top-level measurement frame 2 can be directly moved out from the surface of the desk by rotating the two top-level measurement frames 2 at the top and unfolding them toward the side, so that the disassembly and assembly process of the entire device is simple and convenient, and the width measurement component at the end can also be automatically lifted when it is moved out to avoid blocking the removal process, thereby achieving the effect of quickly switching the desk to be tested.
[0031] Specifically, since the pressing guide roller 7 in the top-level measuring frame 2 is pressed against the surface of the desk table top to be tested, the thickness detection component 3 of the bottom layer can be pressed against the bottom of the desk table top to be tested, forming a clamping effect on the desk table top to be tested and maintaining the clamping state, and the top pressing guide roller 7 moves along the surface of the desk table top to be tested to achieve the purpose of continuous detection. When the detection is completed, the pull rod 13 is manually pulled to control the two rotating arms 5 to rotate and unfold around the support shaft 24 at the end. At this time, the two pressing guide rollers 7 can be directly removed from the surface of the desk table top to be tested, thereby realizing the disassembly process of the entire measuring device. At the same time, two pressing guide rollers 7 are pressed on the table top at the same time to complete the flatness detection. When the surface of the table top is warped, the device will first lift the pressing guide roller 7 in front after detecting the warped area. At this time, it will drive the docking plate 8 corresponding to the pressing guide roller 7 to move upward, thereby causing the conductive contact pieces 12 on the two docking plates 8 to be staggered, thereby generating a disconnection signal, and judging whether the surface of the table top is uneven at this time based on the disconnection signal.
[0032] In this embodiment, the width detection assembly 4 includes a translation channel 15, a first pressure module 16 and a first ball 18. The translation channel 15 is welded to the end of one of the rotating arms 5. The first pressure module 16 is screwed to the end of the translation channel 15, and a first spring rod 21 is inserted on the surface of the first pressure module 16. A baffle 20 is welded to the other end of the first spring rod 21. A movable top block 17 is embedded in the interior of the translation channel 15. The first ball 18 is embedded below the movable top block 17. A limiting convex strip 19 is attached to the side of the movable top block 17. The bottom of the translation channel 15 is in an open state. An inner convex strip is provided inside the bottom opening of the translation channel 15. The movable top block 17 is clamped on the inner side of the translation channel 15 through the limiting convex strip 19 on the side. The rear end of the movable top block 17 is in contact with the surface of the baffle 20, and the side of the baffle 20 is in contact with the inner wall of the translation channel 15.
[0033] Specifically, by the first ball bearing 18 resting against one side of the desk top to be tested and the supporting wheel 26 resting against the other side of the desk top to be tested, a clamping effect on the desk top to be tested can be formed. Subsequently, as the measuring device moves, when the width changes, the distance between the first ball bearing 18 and the supporting wheel 26 will change, and then the distance between the first ball bearing 18 and the first pressure module 16 will change, that is, the first spring rod 21 will be stretched or compressed, so that the detected pressure value will change, and finally, according to the change of the pressure value, it is judged that the width data of the desk top in the area where the detection device moves to has changed. On the other hand, when the top-level detection frame is unfolded by pulling the pull rod 13, the first ball 18 at the bottom will be directly driven to unfold synchronously. At this time, an inclined state will be formed between the first ball 18 and the top support wheel 26, resulting in an increase in the distance between the two, and finally the first ball 18 will completely compress the first spring rod 21. At this time, continue to rotate the top-level measurement frame 2, and the first ball can be directly lifted upward through the edge of the desk table to be tested. At this time, the movable top block 17 moves up, so that the first ball 18 is no longer squeezed to the edge of the desk table to be tested. Therefore, the top-level measurement frame 2 in this state can reach the unfolded state.
[0034] In this embodiment, the bottom measurement frame 1 includes an end plate 22 and a support plate 27. The top of the end plate 22 is integrally formed with a top stop bar 25. A top support wheel 26 is inserted on one side of the top stop bar 25. The two ends of the top stop bar 25 are integrally formed with a support frame 23. The support shaft 24 is embedded in the top of the support frame 23. The bottom of the baffle 20 is integrally formed with a bottom stop bar 36. One end of the support plate 27 is welded to the inner side of the bottom stop bar 36. The top measurement frame 2 as a whole rotates horizontally around the support shaft 24. The thickness of the desk board is detected by the thickness detection component 3, the surface flatness of the desk board is detected in conjunction with the top pressing guide roller 7, and the width of the desk board is detected by the width detection component 4. The detection process of each parameter is directly driven by pulling the top measurement frame 2 to drive the entire device to move in translation, so that the detection process can be carried out continuously, which improves the efficiency of large-scale detection.
[0035] The thickness detection assembly 3 includes a lifting column 30, a second ball 31 and a second pressure module 34. The surface of the lifting column 30 is sleeved with a threaded tube 33. The bottom of the lifting column 30 is welded with a second spring rod 32. The bottom of the threaded tube 33 is screwed with a second pressure module 34. A lever 35 is welded on the side of the shell of the second pressure module 34. The second ball 31 is embedded in the top of the lifting column 30. The top of the threaded sleeve 28 is provided with a lifting hole 29. The top of the lifting column 30 and the second ball 31 are all inserted upward from the inside of the lifting hole 29. The thickness detection assembly 3 is pressed against the bottom of the desk board. Even if there is a edging or blocking structure at the edge of the desk board to be tested, it can still cooperate with the two measuring frames to directly detect the center thickness of such desk boards, thereby avoiding the obstruction of the edging structure to the thickness detection, thereby expanding the measurement range, and increasing flexibility and accuracy.
[0036] Specifically, by pressing the second ball 31 against the bottom of the desk top of the office desk to be tested, as the detection device moves, if the thickness of the area moved over changes, the second ball 31 will move up or down, thereby changing the compression state of the second spring. At this time, the change in pressure data can be detected by the second pressure module 34 at the bottom, and based on the change in pressure data, it can be determined whether the thickness of the desk top of the office desk to be tested in the current area moved over is different from that at other positions. In the initial state, the extension length of the second ball 31 can also be controlled by rotating the lever 35, so that it is suitable for measuring office desks to be tested of different sizes.
