Description

Technical Field

[0001] This application relates to the field of furniture size measurement, and in particular, to a measuring device for efficiently measuring the length of a continuous arc contour of solid wood furniture. Background Art

[0002] Wooden furniture is designed in various forms for consumers to choose from nowadays. For example, an S-shaped bar table with a continuous arc can provide a unique visual experience while accommodating more people. In order to determine how many people an S-shaped bar table can accommodate, how many chairs are needed, and to ensure that the specifications of each bar table produced are relatively uniform during mass production, it is necessary to measure the length of the continuous arc contour of an S-shaped bar table. Therefore, corresponding tools are needed to assist in the measurement.

[0003] There are some existing furniture measuring devices that can perform automated detection after fixing the position of the furniture. For example, a convenient furniture board length measuring device with the publication number CN117490535A.

[0004] Regarding the above related technologies, current furniture size detection devices are more suitable for detecting the straight-line length or width of furniture. For the detection of the arc contour length of large-sized furniture such as an S-shaped bar table, it is still necessary to calculate the final arc length by segmentally detecting data such as the radius and central angle of different arc segments, making the detection relatively inconvenient. Summary of the Invention

[0005] In order to facilitate the detection work, this application provides a measuring device for efficiently measuring the length of a continuous arc contour of solid wood furniture.

[0006] A measuring device for efficiently measuring the length of a continuous arc contour of solid wood furniture provided by this application adopts the following technical solution.

[0007] A measuring device for efficiently measuring the length of a continuous arc contour of solid wood furniture includes a linearly guided rail with a fixed position, a base slidably connected to the linearly guided rail, a column detachably connected to the base, a top electric cylinder detachably connected to the column, a fitting detachably connected to the power rod of the top electric cylinder, and a distance measuring wheel detachably connected to the fitting and capable of closely adhering to the arc contour of the furniture to be measured, rotating, and outputting the length of the path passed.

[0008] By adopting the above technical solution, while the distance measuring wheel moves forward with the base, the power rod of the top electric cylinder extends or contracts so that the distance measuring wheel can stably rotate while keeping in contact with the arc contour of the furniture to be measured, so that the arc contour length of the furniture to be measured can be accurately measured. Even if the furniture to be measured has a continuous arc contour, the measurement of the arc contour length of the furniture can be completed more efficiently and conveniently.

[0009] Optionally, the fitting member includes a rod block detachably connected to the power rod of the top electric cylinder, a cross-moving block slidably connected to the rod block along the length direction of the linear guide rail, two lateral springs for forcing the cross-moving block to move to the center of the rod block, a lateral pressure sensor for detecting the pressure exerted by the two lateral springs on the cross-moving block, and a longitudinal rod provided on the cross-moving block for rotatably arranging the distance measuring wheel. The lateral pressure sensor and the top electric cylinder are electrically connected to a controller.

[0010] By adopting the above technical solution, the elongation of the power rod of the top electric cylinder is adjusted according to the external force in the chord length direction of the arc contour of the furniture to be measured received by the cross-moving block, so that the pressure between the distance measuring wheel and the furniture to be measured is always maintained within a suitable range, so that the base can smoothly move forward along the arc contour of the furniture to be measured at a stable speed during the forward movement.

[0011] Optionally, the longitudinal rod is slidably connected to the cross-moving block along the moving direction of the power rod of the top electric cylinder. A longitudinal spring for forcing the longitudinal rod to move away from the rod block is provided inside the cross-moving block. The cross-moving block is provided with a longitudinal pressure sensor for detecting the pressure exerted by the longitudinal spring on the longitudinal rod and electrically connected to the controller.

[0012] By adopting the above technical solution, the pressure between the distance measuring wheel and the furniture to be measured is further comprehensively detected and monitored, so as to adjust the top electric cylinder in time, and also make the pressure between the distance measuring wheel and the furniture to be measured less likely to be too large.

[0013] Optionally, the column includes a bottom rod detachably connected to the base, a height-adjusting rod slidably connected to the bottom rod to change the height and detachably connected to the top electric cylinder, and a height-adjusting electric cylinder located inside the bottom rod for moving the height-adjusting rod.

[0014] By adopting the above technical solution, the height of the distance measuring wheel is adjusted so that it can be adapted to measure at different heights of the arc contour surfaces of furniture to be measured with different specifications within a certain range.

[0015] Optionally, a positioning table for placing the furniture to be measured is provided on one side in the length direction of the linear guide rail. The positioning table is detachably connected with a wide positioning strip and a long positioning strip that are perpendicular to each other, close to each other, and for the furniture to be measured to approach.

[0016] By adopting the above technical solution, the position of the furniture to be measured relative to the linear guide rail is not likely to have a large deviation, so that the distance measuring wheel is not likely to contact the furniture to be measured too early or too late when initially moving, so that the measurement work can be carried out smoothly and quickly.

[0017] Optionally, the long positioning bar and the wide positioning bar are both provided with bar sliders, and the bar sliders are detachably connected with infrared sensors for detecting the distance between the furniture to be measured, and the infrared sensors are electrically connected with a controller.

[0018] By adopting the above technical solution, the position of the furniture during measurement can be detected to prevent large errors in the measurement results caused by the position deviation of the furniture.

[0019] Optionally, the bar slider of the long positioning bar is slidably connected to the long positioning bar along the length direction of the long positioning bar, and the bar slider of the wide positioning bar is slidably connected to the wide positioning bar along the length direction of the wide positioning bar.

[0020] By adopting the above technical solution, the position of the infrared sensor can be adjusted adaptively to match different models of furniture with position changes at the bottom support.

[0021] Optionally, the bar slider is threadedly connected with a stop member that can abut against the long positioning bar or the wide positioning bar.

[0022] By adopting the above technical solution, while facilitating the adjustment of the position of the bar slider, it can also ensure that the position of the bar slider is not easily moved randomly after adjustment.

[0023] Optionally, there is an included angle between the length direction of the long positioning bar and the length direction of the linear guide rail, and the distance between one end of the long positioning bar close to the wide positioning bar and the linear guide rail is the largest.

[0024] By adopting the above technical solution, the position of the furniture to be measured is adjusted to a certain inclination to reduce the situation where the length direction of the top electric cylinder power rod is parallel to the tangents at various points of the arc contour of the furniture to be measured, so as to ensure that the distance measuring wheel can closely adhere to the arc contour surface of the furniture to be measured.

[0025] Optionally, there is an inner bar on the side of the long positioning bar away from the wide positioning bar, and the inner bar is located on the side of the long positioning bar away from the linear guide rail.

[0026] By adopting the above technical solution, the distance measuring wheel first contacts the convex side of the arc contour surface of the furniture to be measured towards the outside of the linear guide rail at the beginning, so that it is not necessary to align the distance measuring wheel with the concave side of the arc contour surface of the furniture to be measured away from the linear guide rail at the beginning, facilitating the rapid development of the measurement work.

[0027] In summary, the present application has at least the following beneficial effects.

[0028] While the distance measuring wheel moves forward with the base, the power rod of the top electric cylinder extends or retracts so that the distance measuring wheel can rotate stably while remaining in contact with the arc-shaped contour of the furniture to be measured, enabling the arc-shaped contour length of the furniture to be measured more accurately. Even if the furniture to be measured has a continuous arc-shaped contour, the measurement of the arc-shaped contour length of the furniture can be completed more efficiently and conveniently.

Detailed Description of the Embodiment

[0031] The following further describes the present application in detail with reference to the drawings.

[0032] An embodiment of the present application discloses a measuring device for efficiently measuring the length of a continuous arc-shaped contour of a solid wood furniture. Referring to Figure 1 , it includes a linear guide rail 1 detachably connected to the ground. A positioning table 44 for placing the furniture to be measured is detachably connected to the ground on one side in the length direction of the linear guide rail 1. The length direction of the linear guide rail 1 is consistent with the length direction of the positioning table 44. The linear guide rail 1 is slidably connected with a base 2 along its own length direction. A servo motor and rollers can be arranged inside the base 2 to enable the movement of the base 2. The base 2 is provided with a column 3. A top electric cylinder 4 with the length direction of the power rod perpendicular to the length direction of the linear guide rail 1 is installed on the upper part of the column 3. A fitting member 5 is installed on the power rod of the top electric cylinder 4. A distance measuring wheel 51 capable of fitting the arc-shaped contour of the furniture to be measured and rotating is installed on the fitting member 5. The distance measuring wheel 51 is equipped with its own encoder and electrically connected to a controller 56, so that by counting the number of rotations of the distance measuring wheel 51 and combining the preset perimeter of the distance measuring wheel 51 in the controller 56, the path length passed by the distance measuring wheel 51 can be calculated, that is, the length of the arc-shaped contour of the furniture to be measured passed by the distance measuring wheel 51.

[0033] Referring to Figure 1, a wide positioning strip 45, a long positioning strip 47 and an inner strip 31 are detachably connected to the upper surface of the positioning table 44. The wide positioning strip 45 and the long positioning strip 47 are perpendicular to each other and their ends are close to each other. The convex end of the arc-shaped contour of the furniture to be measured is placed corresponding to the two adjacent ends of the wide positioning strip 45 and the long positioning strip 47, so that the chord length direction of the arc-shaped contour of the furniture to be measured is as parallel as possible to the length direction of the long positioning strip 47, and there is a certain small included angle between the length direction of the long positioning strip 47 and the length direction of the linear guide rail 1. The distance between the end of the long positioning strip 47 close to the wide positioning strip 45 and the linear guide rail 1 is the largest, so that the distance measuring wheel 51 can keep close to the surface of the arc-shaped contour of the furniture to be measured during the movement. The inner strip 31 is located on the side of the long positioning strip 47 away from the wide positioning strip 45, and the inner strip 31 is located on the side of the long positioning strip 47 away from the linear guide rail 1. And the inner strip 31 can also be arc-shaped and the concave surface of the inner strip 31 faces the linear guide rail 1, so that the concave side of the arc-shaped contour of the furniture to be measured away from the wide positioning strip 45 can correspond to the inner strip 31, so that the placement position of the furniture to be measured is not easy to be wrong.

[0034] Refer to Figure 2 and Figure 3 , both the long positioning strip 47 and the wide positioning strip 45 are slidably connected with strip sliders 48. Along the length direction of itself, several strip sliders 48 are arranged on the long positioning strip 47. Only one strip slider 48 can be provided on the wide positioning strip 45. Each strip slider 48 is detachably connected with an infrared sensor 46 electrically connected to the controller 56. Each infrared sensor 46 detects the distance between itself and the furniture to be measured. So that once the furniture to be measured has a position offset during the measurement process, the distance value detected by at least one infrared sensor 46 changes. At this time, the controller 56 stops the measurement work and makes the external sound and light alarm emit an alarm. In addition, each strip slider 48 is threadedly connected with a stop member 49 that can abut against the corresponding long positioning strip 47 or wide positioning strip 45, so that the strip slider 48 is not easy to move again after the adjustment is completed.

[0035] Refer to Figure 2 , the column 3 includes a bottom rod 41 that is vertically and detachably connected to the upper surface of the base 2. The bottom rod 41 is inserted with a height-adjusting rod 42 for detachably connecting the top electric cylinder 4. The base 2 is detachably connected with a height-adjusting electric cylinder 43 located inside the bottom rod 41, so that the height of the distance measuring wheel 51 can be changed to better adapt to the different heights of the arc-shaped contours of different models of furniture to be measured.

[0036] Refer to Figure 2, the fitting member 5 includes a rod block 52 detachably connected to the end of the power rod of the top electric cylinder 4. The rod block 52 is slidably connected with a transverse moving block 53 along the length direction of the linear guide rail 1. On both opposite sides inside the rod block 52, there are transversely pressure sensors 55 detachably connected and electrically connected to the controller 56. On the closer sides of the two transversely pressure sensors 55, there are transversely springs 54 detachably connected. The closer ends of the two transversely springs 54 are detachably connected to the opposite side surfaces of the transverse moving block 53, so that the transverse moving block 53 tends to move to the center of the rod block 52. And, the transverse moving block 53 is slidably connected with a longitudinal moving rod 57 along the length direction of the power rod of the top electric cylinder 4. Inside the transverse moving block 53, there is a longitudinally pressure sensor 59 detachably connected and electrically connected to the controller 56. Between the longitudinally pressure sensor 59 and the longitudinal moving rod 57, there is a longitudinally spring 58 detachably connected. The longitudinally spring 58 forces the longitudinal moving rod 57 to move towards the furniture to be measured. One end of the longitudinal moving rod 57 located in the transverse moving block 53 has a larger cross-sectional area. At the same time, a rectangular piece is detachably connected to the surface of the transverse moving block 53 through bolts to prevent the longitudinal moving rod 57 from randomly detaching from the transverse moving block 53. The end of the longitudinal moving rod 57 is provided for the ranging wheel 51 to rotate. The top electric cylinder 4 is electrically connected to the controller 56.

[0037] The base 2 moves forward at a set speed, and a pressure range is preset in the controller 56. At least one of the pressure values detected by the transversely pressure sensor 55 and the longitudinally pressure sensor 59 should be within the preset pressure range, otherwise the base 2 stops moving and the corresponding external sound and light alarm gives an alarm. When the pressure value detected by one of the transversely pressure sensor 55 and the longitudinally pressure sensor 59 is less than the minimum value of the preset pressure range, the power rod of the top electric cylinder 4 extends; when the pressure value detected by one of the transversely pressure sensor 55 and the longitudinally pressure sensor 59 is greater than or equal to the maximum value of the preset pressure range, the power rod of the top electric cylinder 4 shortens, so as to accurately control the pressure value between the ranging wheel 51 and the furniture to be measured.

[0038] The implementation principle of a measuring device for efficiently measuring the length of the continuous arc contour of a solid wood furniture in an embodiment of the present application is as follows: Place the convex side of the arc contour of the furniture to be measured corresponding to the long positioning strip 47 and the wide positioning strip 45, and then the base 2 moves forward so that the ranging wheel 51 abuts against the end of the convex side of the arc contour of the furniture to be measured. As the base 2 moves forward, the extension length of the power rod of the top electric cylinder 4 is controlled according to the pressure values detected by the transversely pressure sensor 55 and the longitudinally pressure sensor 59, so that the ranging wheel 51 can smoothly rotate closely against the surface of the arc contour of the furniture to be measured until the base 2 moves to the designated position and stops, that is, the length of the arc contour of the furniture to be measured is obtained.

[0039] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore: All equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
