Abstract
Description
Technical Field
[0001] This invention relates to the field of positioning device technology, and in particular to a positioning device with plate width measurement and guiding functions. Background Technology
[0002] A mechanical positioning device with guiding function includes several main parts such as a guiding mechanism, a positioning detection unit, and a drive control system, as well as other auxiliary equipment. It mainly includes guide rails, position detectors, drive motors, and transmission linkages. The end effector is responsible for using the guiding positioning information to specifically adjust the mechanical motion path, ensuring the displacement accuracy of the target component meets the requirements. Guide wheels are needed to achieve stable guiding.
[0003] Existing positioning devices are inconvenient for measuring the orientation of the sheet material when measuring its thickness, have weak vibration resistance, low measurement accuracy, and are difficult to maintain the measured value when detached from the sheet material. Multiple measurements are required to obtain the average sheet material thickness, resulting in low work efficiency. When drawing direction lines, it is inconvenient to observe the angle, making it difficult to draw direction lines. Furthermore, the measuring ruler is unstable when drawing direction lines, resulting in low drawing accuracy.
[0004] Therefore, there is an urgent need to design a solution to the above problems. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a positioning device with sheet width measurement and guiding functions.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A positioning device with sheet width measurement and guiding functions includes a lower positioning plate. A fixing block is fixedly connected to one outer wall of the lower positioning plate. A thickness gauge is provided on the top outer wall of the fixing block, and the thickness gauge can be zeroed by adjusting the fixing block. A thickness gauge scale is engraved on one outer wall of the thickness gauge. A first telescopic rod is fixedly connected to one outer wall of the positioning plate, and a second telescopic rod is fixedly connected to one outer wall of the positioning plate. The first and second telescopic rods have the same extension length. An upper positioning plate is fixedly connected to the top of the first telescopic rod. A positioning frame is provided on one side of the outer wall. A first positioning bolt is threaded onto the outer wall of one side of the positioning frame and can penetrate the positioning frame. An angle plate is fixedly connected to the top outer wall of the upper positioning plate. An angle scale is engraved on the top outer wall of the angle plate. A direction guide plate is provided on the top outer wall of the upper positioning plate. A viewing groove is opened on one side of the outer wall of the direction guide plate and penetrates the direction guide plate. An anti-detachment block is fixedly connected to one side of the outer wall of the direction guide plate. A second positioning bolt is provided on one side of the top of the direction guide plate, and the direction guide plate can be fixed after the second positioning bolt is tightened.
[0008] Furthermore, the thickness gauge is located inside the positioning groove, and the thickness gauge scale can be kept stationary by tightening the first positioning bolt.
[0009] Furthermore, the first telescopic rod is provided with a lower cylinder inside, and an inner cylinder is sleeved inside the lower cylinder. A locking bolt is threaded to the outer wall of one side of the lower cylinder, and the inner cylinder can slide inside the lower cylinder.
[0010] Furthermore, a rectangular block is provided inside the lower positioning plate, a left convex tooth is fixedly connected to one side of the outer wall of the lower positioning plate, a middle convex tooth is fixedly connected to one side of the outer wall of the lower positioning plate, and a right convex tooth is fixedly connected to one side of the outer wall of the lower positioning plate, and the left convex tooth, the middle convex tooth and the right convex tooth are located on the same side of the rectangular block.
[0011] Furthermore, the angle plate is arc-shaped and has a hollowed-out inner side.
[0012] Furthermore, the lower positioning plate has the same shape as the upper positioning plate, and the two ends of the outer wall on one side of the rectangular block are arc-shaped.
[0013] Furthermore, the thickness gauge has a measuring range of 0.5-50mm, a minimum scale division of 0.05mm, and an error of ≤0.02mm when zeroing by adjusting the fixing block; and the fit clearance between the thickness gauge and the positioning groove is 0.01-0.03mm. After tightening the first positioning bolt, the positional deviation of the thickness gauge is ≤0.03mm, ensuring that the measurement value remains stable after detaching from the plate.
[0014] Furthermore, the extension range of both the first and second telescopic rods is 50-200mm, the sliding speed of the inner cylinder within the lower cylinder is 10-30mm / s, and the tightening torque of the locking bolts is 5-10N·m. When the locking bolts are fully tightened, the axial movement of the inner cylinder is ≤0.05mm, and the radial offset is ≤0.03mm, ensuring that the parallelism error between the upper and lower positioning plates is ≤0.1mm / m.
[0015] Furthermore, the tooth height of the left, middle, and right convex teeth is 2-5mm, the tooth spacing is 10-15mm, and the tooth tips of the three teeth are on the same plane (flatness error ≤0.02mm). During measurement, the contact pressure between the three convex teeth and the plate is maintained at 1-3N. Thickness data at three points are collected simultaneously using a thickness gauge, and the average value is automatically calculated (calculation accuracy ≤0.01mm). Compared with single-point measurement, the error is reduced by 40%-60%.
[0016] Furthermore, the radius of the arc of the angle plate is 50-80mm, the range of the angle scale is 0°-180°, and the minimum division value is 0.5°; the rotation angle range of the direction guide plate around the second positioning bolt is 0°-360°, and the angle positioning error during adjustment is ≤0.5°; the width of the perspective groove is 3-5mm, the length is 50-80mm, the straightness error of the groove wall is ≤0.02mm, and the straightness deviation when drawing the direction line is ≤0.1mm / m.
[0017] The beneficial effects of this invention are as follows:
[0018] 1. The first positioning bolt, locking bolt and second positioning bolt can be firmly fixed to the plate, preventing the positioning device from deviating, with strong vibration resistance, more accurate measurement, and the measurement value can remain unchanged when detached from the plate, which improves the stability of the measuring device and increases the data recording time.
[0019] 2. By setting left-side, middle, and right-side convex teeth, the measurement accuracy is improved. Three points are measured simultaneously, and the scale directly reads the average value of the three points, further improving the reliability of the measurement. The large contact area allows for stable fixation on the plate surface when using the guiding function, providing stability to the equipment.
[0020] 3. The directional guide plate and perspective groove improve the accuracy of angle measurement. Direction lines can be drawn in the perspective groove with high straightness and small gap between the line and the material. This makes drawing direction lines more stable and accurate, reduces measurement errors, and makes it more convenient to draw different directions. Attached Figure Description

[0029] In this invention, the thickness gauge 5 is located inside the positioning groove 15, and the scale of the thickness gauge 5 can be kept stationary by locking the first positioning bolt 8, which improves the perpendicularity of the measurement and can remember the data of the last measurement.
[0030] In this invention, a lower cylinder 16 is provided inside the first telescopic rod 3, and an inner cylinder 17 is sleeved inside the lower cylinder 16. A locking bolt 18 is threadedly connected to the outer wall of one side of the lower cylinder 16, and the inner cylinder 17 can slide inside the lower cylinder 16, which maintains the stability of the measurement. The two-point support improves the measurement accuracy.

The three-point positioning improves the measurement accuracy. The three positioning points are directly measured, and the reading is the average value of the three points.
[0032] In this invention, the angle plate 9 is arc-shaped and has a hollowed-out inner side, which improves the visibility of the angle and makes the angle measurement more accurate.
[0033] In this invention, the lower positioning plate 1 and the upper positioning plate 4 have the same shape, and the two ends of the outer wall of one side of the rectangular block 19 are rounded, providing ergonomic protection to prevent the user from being injured by sharp corners.
[0034] In this invention, the measuring range of the thickness gauge 5 is 0.5-50mm, the minimum division value of the thickness gauge scale 6 is 0.05mm, and the error when zeroing by adjusting the fixing block 2 is ≤0.02mm; and the fit clearance between the thickness gauge 5 and the positioning groove 15 is 0.01-0.03mm. After tightening the first positioning bolt 8, the position deviation of the thickness gauge 5 is ≤0.03mm, ensuring that the measurement value remains stable after being removed from the plate.
[0035] In this invention, the telescopic range of the first telescopic rod 3 and the second telescopic rod 23 is 50-200mm, the sliding speed of the inner cylinder 17 in the lower cylinder 16 is 10-30mm / s, and the locking torque of the locking bolt 18 is 5-10N·m. When the locking bolt 18 is fully tightened, the axial movement of the inner cylinder 17 is ≤0.05mm, and the radial offset is ≤0.03mm, ensuring that the parallelism error between the upper positioning plate 4 and the lower positioning plate 1 is ≤0.1mm / m.
[0036] In this invention, the tooth height of the left convex tooth 20, the middle convex tooth 21, and the right convex tooth 22 are all 2-5mm, and the tooth spacing is 10-15mm. The tooth tips of the three are on the same plane (flatness error ≤0.02mm). During measurement, the contact pressure between the three convex teeth and the plate is maintained at 1-3N. Thickness data at three points are collected simultaneously by a thickness gauge 5, and the average value is automatically calculated (calculation accuracy ≤0.01mm). Compared with single-point measurement, the error is reduced by 40%-60%.
[0037] In this invention, the radius of the arc of the angle plate 9 is 50-80mm, the range of the angle scale 10 is 0°-180°, and the minimum division value is 0.5°; the rotation angle range of the direction guide plate 11 around the second positioning bolt 14 is 0°-360°, and the angle positioning error during adjustment is ≤0.5°; the width of the perspective groove 13 is 3-5mm, the length is 50-80mm, the straightness error of the groove wall is ≤0.02mm, and the straightness deviation when drawing the direction line is ≤0.1mm / m.
[0038] Working principle: In use, loosen the locking bolt 18 and the first positioning bolt 8, and stretch the first telescopic rod 3 to a scale thicker than the material. Then, with the toothed side of the rectangular block 19 facing the material, measure three points simultaneously. The scale directly reads the average value of the three points, further improving the reliability of the measurement. Next, place the material between the lower positioning plate 1 and the upper positioning plate 4, and then manually tighten the lower positioning plate 1 and the upper positioning plate 4, tightening the locking bolt 18. At this point, the thickness gauge scale 6 can be observed. Tighten the first positioning bolt 8 to prevent the scale from deviating. This is how the thickness of the material is measured. The lower positioning plate 1 and the upper positioning plate 4 are firmly fixed to the material. To prevent the positioning device from deviating, it has strong vibration resistance and more accurate measurement. It can maintain the measurement value when detached from the board, which improves the stability of the measuring device. Then, loosen the second positioning bolt 14, adjust the direction of the direction guide block 11 according to the preset angle, and the direction of the direction guide block 11 can be observed from the perspective groove 13. Then tighten the second positioning bolt 14, use a marker to insert into the perspective groove 13, and move the marker to obtain the preset direction line. The straightness of the line drawn is high, the gap between the direction guide block 11 and the board is small, the line drawing is more stable, the measurement error is reduced, and it is more convenient to draw different directions. Finally, loosen the locking bolt 18, remove the positioning device, and the measurement is completed.
