Description

Technical Field

[0001] This utility model belongs to the field of data acquisition fixture technology, and more specifically, relates to a multi-angle data acquisition fixture for rapid measurement. Background Technology

[0002] The defect rate of oblique positioning keyways in three-axis horizontal machining centers is high, often requiring welding and rework, which seriously affects delivery time and increases unnecessary workload. Existing measurement solutions include: one method involves the programmer milling a reference point on the edge of the sheet metal to position the oblique keyway; however, this is affected by the distance between the reference point and the keyway, which itself has errors, and the error increases with the distance. Furthermore, this method is time-consuming, and if the error becomes too large, it cannot be corrected in time, requiring rework. Another method uses a small dial indicator to measure the angle of the frame, taking data from the surface to the point. This method is affected by many factors in practical use, such as angle and whether the sheet metal is magnetic, resulting in unstable reliability. Therefore, a convenient measuring tool is needed that can quickly confirm the position of oblique keyways, oblique teeth, and oblique frames. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a multi-angle data acquisition fixture for rapid measurement, which can meet the measurement requirements of convenient operation and rapid confirmation of the position of inclined grooves, inclined teeth and inclined frames.

[0004] This utility model discloses a multi-angle data acquisition fixture for rapid measurement. The data acquisition fixture is integrally formed and includes a data acquisition plane and a data acquisition curved surface, which are tangent to each other. During data acquisition, the data acquisition plane and the data acquisition curved surface are respectively in close contact with the two surfaces of the position to be measured. The data acquisition fixture is provided with a connecting part that connects to the position to be measured. Since the position of the inclined groove is a point on a line segment from a surface, it cannot be accurately measured by existing measurement methods on the machining site. By stretching the line segment into a surface and adding mathematical calculations, the position can be accurately obtained. By pressing the two inner surfaces of the multi-angle data acquisition fixture in close contact with the two surfaces of the position to be measured, there is no need to use a dial indicator for alignment. The original surface-to-point measurement is changed to surface-to-surface measurement, making point counting more convenient and readings more accurate. The operator only needs to input the angle, and the machine tool automatically calculates, without much manual calculation.

[0005] As a further improvement of this utility model, it also includes a protective surface, with the data acquisition surface located between the protective surface and the data acquisition plane. The protective surface is tangent to the data acquisition surface and perpendicular to the data acquisition plane, thereby increasing the measurement range to process inclined grooves of different angles. The processable angle range is 0.01° to 89.9°.

[0006] As a further improvement of this utility model, the data acquisition plane and the protective surface form an L-shape, the connecting member is a magnet, the data acquisition plane is provided with a groove, the magnet is embedded in the groove, the magnet is fixedly connected to the data acquisition plane, and the groove provides installation space for the magnet.

[0007] As a further improvement of this utility model, the distance between any two points on the edge of the cross-section of the data acquisition surface does not exceed the width of the two planes of the data acquisition plane, so that the edge of the data acquisition plane protects the data acquisition surface and prevents the data acquisition surface from being damaged by bumps, which would reduce the measurement accuracy.

[0008] As a further improvement of this utility model, the height of the magnet does not exceed the depth of the groove, ensuring that the data acquisition plane can be closely attached to the three-axis horizontal machining tool when acquiring data, thus ensuring measurement accuracy.

[0009] As a further improvement of this utility model, the projection of the data acquisition surface onto the inner wall of the data acquisition plane does not intersect with the magnet, thus preventing interference when the magnet is magnetically connected to the machine tool.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the data acquisition plane and data acquisition curved surface on the inner side of the multi-angle data acquisition fixture are closely attached to the reference surface of the position to be measured on the three-axis horizontal machining center, eliminating the need for dial indicator alignment and simplifying operation; the data acquisition method changes from surface-to-point to surface-to-surface, making point counting more convenient and readings more accurate; the operator only needs to input the angle, and the machine tool automatically calculates the result, eliminating the need for excessive manual calculation; the data acquisition plane and data acquisition curved surface are integrally formed, resulting in a simple structure.

[0017] Specific Implementation Example 1: Please refer to... Figures 1-4 This utility model relates to a multi-angle data acquisition fixture for rapid measurement. The data acquisition fixture is integrally formed and includes a data acquisition plane 1, a data acquisition curved surface 2, and a protective surface 4. The data acquisition plane 1 and the data acquisition curved surface 2 are tangent to each other. The data acquisition curved surface 2 is located between the protective surface 4 and the data acquisition plane 1. The protective surface 4 and the data acquisition curved surface 2 are tangent to each other. When acquiring data, the data acquisition plane 1 and the data acquisition curved surface 2 are respectively in close contact with the reference surface of the position to be measured. The data acquisition fixture is provided with a connecting piece that is connected to the position to be measured.

[0018] In a further embodiment, such as Figure 1 As shown, the connector is a magnet 3, and the data retrieval plane 1 has a groove 1-1. The magnet 3 is embedded in the groove 1-1, and the magnet 3 is fixedly connected to the data retrieval plane 1.

[0019] In a further embodiment, such as Figure 2 As shown, the data acquisition plane 1 and the protective surface 4 are two mutually perpendicular planes. The data acquisition plane 1 is tangent to the data acquisition curved surface 2, which increases the measurement range to process inclined grooves of different angles. The processable angle range is 0.01° to 89.9°.

[0020] In a further embodiment, such as Figure 2 As shown, the projection of the data acquisition surface 2 onto the inner wall of the data acquisition plane 1 does not intersect with the magnet 3, preventing interference when the magnet 3 is magnetically connected to the machine tool.

[0021] In a further embodiment, such as Figure 2 As shown, the data acquisition plane 1 and the protective surface 4 form an L-shape, and the groove 1-1 is opened on the inner side of the long plane to provide installation space for the magnet 3.

[0022] In a further embodiment, such as Figure 2 As shown, the distance between any two points on the edge of the cross section of the data acquisition surface 2 does not exceed the width of the protective surface 4, so that the edge of the protective surface 4 protects the data acquisition surface 2 and prevents the data acquisition surface 2 from being damaged by bumps, which would reduce the measurement accuracy.

[0023] In a further embodiment, such as Figure 3 As shown, the height of magnet 3 does not exceed the depth of groove 1-1, ensuring that the data acquisition plane 1 can be closely attached to the three-axis horizontal machining center when acquiring data, thus ensuring measurement accuracy.

[0024] In use, the two inner sides of the multi-angle data acquisition jig 1 are pressed against the reference surface of the position to be measured on the three-axis horizontal machining center. After the magnet 3 is magnetically attracted and fixed at the position to be measured, the data acquisition begins. The angle between the reference surface and the multi-angle data acquisition jig is measured. The operator inputs the angle, and the machine tool automatically calculates the position of the inclined groove to the reference surface. According to the operator's needs, the measured position is stored in any coordinate system of the machine tool for calibration. There is no need to use a dial indicator for alignment. The original surface-to-point data acquisition is changed to surface-to-surface data acquisition, which makes point counting more convenient and the reading more accurate.
