Description

Technical Field

[0001] This invention relates to a digital measuring device and method for component processing and installation angles, belonging to the field of angle measurement technology. Background Technology

[0002] In terms of angle measurement, the commonly used measurement methods are angle ruler measurement and total station measurement.

[0003] The angle gauge measurement method involves placing an angle gauge at the angle to be measured, with the bottom of the gauge parallel to one side of the component. The gauge is then adjusted to fit the angle of the component, and the angle is determined by reading the scale on the gauge. This method relies on manual alignment and reading, leading to inconsistent results and low reliability.

[0004] The total station measurement method involves setting the total station to angle measurement mode, aligning it with one side of the component to be measured, setting the total station's horizontal circle reading to 0°0'0", and then aligning the total station with the other side of the component. The horizontal circle reading at this point is the angle to be measured. This method is suitable for large steel components but not for small components, and it has limitations regarding the size of the steel component being measured. Summary of the Invention

[0005] To address the problems existing in the measurement of included angles in the prior art, this application provides a digital measurement device and method for component processing and installation angles, which has the advantages of high measurement accuracy, wide applicability, and fast measurement speed.

[0006] To solve the above technical problems, the present invention includes the following technical solutions:

[0007] A digital measuring device for component processing and installation angle, wherein the two sides of the included angle are the first side and the second side of the component, and the measuring device includes an A plate, a B plate, a rotating component, a first laser assembly, and a second laser assembly;

[0008] One end of plate A and plate B are rotatably connected by a rotating component;

[0009] The first laser component and the second laser component are disposed on plate B. The first laser component includes two first laser rangefinders symmetrically arranged along plate B. The second laser component includes two second laser rangefinders symmetrically arranged along plate B. The angles between the two first laser rangefinders and plate B, and the angles between the two second laser rangefinders and plate B are both θ. The laser lines of the two first laser rangefinders and the laser lines of the two second laser rangefinders are in the same plane, and the plane is perpendicular to plate B, plate A, and the axis of rotation of the rotating component.

[0010] Furthermore, the first laser component is fixedly connected to plate B, and the second laser component is slidably connected to plate B, thereby adjusting the distance between the first laser component and the second laser component.

[0011] Accordingly, the present invention also provides a method for digitally measuring the angle of component processing and installation, using the aforementioned digital measuring device for component processing and installation angles. The measurement method includes the following steps:

[0012] Step 1: Set the measuring device at the included angle of the component, so that the rotation axis of the rotating component is parallel to the inside corner line of the included angle, and place plate A parallel to the first side of the component. Rotate plate B to a suitable position. The included angle between plate B and plate A is recorded as β1, and the included angle between plate B and the second side of the component is recorded as β2.

[0013] Step 2: Use the first laser component to measure the distance L2 of plate A and the distance L2' of the second side of the component, and use the second laser component to measure the distance L1 of plate A and the distance L1' of the second side of the component. The distance between the first laser component and the second laser component is L.

[0014] Step 3: β1, β2, and γ can be calculated using the formula, where γ is the angle between the first side and the second side of the component; where,

[0015]

[0016]

[0017] γ = β1 + β2.

[0018] Furthermore, the first laser component is fixedly connected to plate B, and the second laser component is slidably connected to plate B;

[0019] In step one, first adjust the position of the second laser component on plate B so that the length of the second laser component matches the length of the first side and the second side of the component. Then determine the distance between the first laser component and the second laser component as L.

[0020] The present invention, by adopting the above technical solution, has the following advantages and positive effects compared with the prior art: The component processing and installation angle digital measurement device provided in this embodiment only requires that plate A be pressed tightly against the first side of the component, and plate B be rotated to be in a suitable position. The included angle γ is divided into included angles β1 and β2. Only the distance of plate A and the distance of the second side of the component need to be collected by the first laser component and the second laser component. β1, β2 and γ can be obtained by calculation. It can be applied to angle measurement in the range of 0° to 180°. It is simple to operate, convenient to collect data, and can improve measurement accuracy and measurement efficiency.

[0028] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a digital measurement device and method for component processing and installation angles according to the present invention. The advantages and features of the present invention will become clearer from the following description. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0029] Example 1

[0030] like Figure 1 As shown in the figure, this embodiment provides a digital measuring device for component processing and installation angles to measure the included angle of a component, such as a steel component, the steel component including the included angle formed by the first side 1 and the second side 2 of the component, and the measuring device is used to measure the included angle.

[0031] The measuring device includes an A plate 10, a B plate 11, a rotating component 12, a first laser assembly 20, and a second laser assembly 30. One end of the A plate 10 and the B plate 11 are rotatably connected by the rotating component 12. The first laser assembly 20 and the second laser assembly 30 are disposed on the B plate 11. The first laser assembly 20 includes two first laser rangefinders 21 symmetrically arranged along the B plate 11, and the second laser assembly 30 includes two second laser rangefinders 31 symmetrically arranged along the B plate 11. The angles between the two first laser rangefinders, the two second laser rangefinders, and the B plate are all θ. The laser lines of the two first laser rangefinders and the two second laser rangefinders are in the same plane, and the plane is perpendicular to the rotation axis of the B plate 11, the A plate 10, and the rotating component 12.

[0032] Combination Figure 1 and Figure 2As shown, the measurement principle of the measuring device provided in this embodiment is as follows: Plate A 10 is placed tightly against the first side 1 of the component. Component 12 is rotated to the angle between the components. Plate B 11 is rotated so that it is positioned between Plate A and the second side of the component. The angle between Plate A 10 and Plate B 11 is denoted as β1, and the angle between Plate B 11 and the second side 2 of the component is denoted as β2. The distance L2 to Plate A 10 and the distance L2' to Plate B 11 are measured using the first laser component 20. The distance L1 to Plate A 10 and the distance L1' to Plate B 11 are measured using the second laser component 30. The distance between the first laser component 20 and the second laser component 30 is L. Using auxiliary lines, a triangle with side lengths L1-L2 and L, an included angle θ, and the diagonal of side length L1-L2 being β1 can be constructed. From this, the following can be calculated:

[0033]

[0034] Similarly, we can obtain:

[0035]

[0036] Therefore, the included angle γ between the first side 1 and the second side 2 of the component can be obtained, where γ = β1 + β2.

[0037] In one specific embodiment, the first laser component 20 is fixedly connected to the B plate 11, and the second laser component 30 is slidably connected to the B plate 11. This allows adjustment of the position of the second laser component 30 on the B plate 11, matching the lengths of the first side 1 and the second side 2 of the component, thus improving the adaptability of the measuring device. The sliding connection can be a groove-slider connection, where a groove is provided on the B plate 11, perpendicular to the axis of rotation of the rotating component 12. The second laser component 30 can move along the groove via a slider and can be fixed by a fixing component, such as a tightening screw. Alternatively, the sliding connection can be a rail-roller connection, where a rail is provided on the B plate 11, and the second laser component 30 moves along the rail via rollers matching the rail and can be fixed by a fixing component. The B plate 11 can also be a rod, with the first laser component 20 and the second laser component 30 fitted onto the rod, allowing them to slide and brake along the rod.

[0038] In one specific embodiment, the measuring device further includes a processor, which has a preset formula to automatically calculate angles β1, β2, and γ.

[0039] The component processing and installation angle digital measurement device provided in this embodiment only requires placing plate A 10 tightly against the first side 1 of the component, rotating plate B 11 to position plate B 11 in a suitable position, dividing the included angle γ into included angles β1 and β2, and only needing to collect the distance of plate A 10 and the distance of the second side 2 of the component through the first laser component 20 and the second laser component 30, and then calculating β1, β2, and γ. This measurement device can be used to measure angles from 0° to 180°, is simple to operate, convenient to collect data, and can improve measurement accuracy and efficiency.

[0040] Example 2

[0041] Combination Figure 1 and Figure 2 As shown in the figure, this embodiment provides a digital measurement method for the processing and installation angle of a component. The component includes an included angle formed by a first side 1 and a second side 2 of the component. The included angle is measured using the measuring device described in Embodiment 1. The measurement method includes the following steps:

[0042] Step 1: Set the measuring device at the included angle of the component, make the rotation axis of the rotating component 12 parallel to the inside corner line of the included angle, make plate A 10 parallel to the first side 1 of the component, rotate plate B 11, and record the included angle between plate B 11 and plate A 10 as β1, and the included angle between plate B 11 and the second side 2 of the component as β2.

[0043] Step 2: Use the first laser component 20 to measure the distance L2 of plate A 10 and the distance L2' of the second side of the component, and use the second laser component 30 to measure the distance L1 of plate A 10 and the distance L1' of the second side of the component. The distance between the first laser component 20 and the second laser component 30 is L.

[0044] Step 3: β1, β2, and γ can be calculated using the formula, where γ is the angle between the first side and the second side of the component; where,

[0045]

[0046]

[0047] γ = β1 + β2.

[0048] It should be noted that the first side 1 and the second side 2 of the component are often two hinged planes, and the intersection of the two planes is the inside corner line.

[0049] In one specific embodiment, when both the first side 1 of the component and plate A 10 are planar, parallelism can be achieved by having plate A 10 in close contact with the first side 1 of the component. When there are obstacles on the first side 1 of the component, making it impossible for plate A 10 to be in close contact with the first side 1 of the component, a pad of the same thickness can be placed in the non-obstacle area, and plate A is placed on the pad to make plate A 10 parallel to the first side 1 of the component.

[0050] In one specific embodiment, the first laser component 20 is fixedly connected to the B plate 11, and the second laser component 30 is slidably connected to the B plate 11. In step one, the position of the second laser component 30 on the B plate 11 is first adjusted so that the second laser component 30 matches the first side 1 and the second side 2 of the component. Then, the distance between the first laser component 20 and the second laser component 30 is determined to be L.

[0051] In one specific embodiment, the rotating component 12 can be a hinge, with its two sides fixedly connected to plate A 10 and plate B 11 respectively. The rotating component 12 can also be a bearing, with its outer ring connected to plate A 10 and its inner ring connected to plate B 11. In step one, when the rotating component 12 is pressed against the included angle, the axis of rotation of the rotating component 12 is parallel to the inner corner line of the included angle. When there is an obstacle at the included angle that prevents the rotating component 12 from pressing against the included angle, an abutment conversion plate can be set at the included angle. The abutment conversion plate can be a U-shaped plate or two rectangular plates of the same size. When the abutment conversion plate presses against the included angle and the rotating component 12 presses against the abutment conversion plate, the axis of rotation of the rotating component 12 is parallel to the inner corner line of the included angle.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
