Description

Technical Field

[0001] The present invention relates to a fixture used in a work field, and in particular to a fixed fixture, a detection device and an automatic detection system used in detection operations. Background Art

[0002] In the work field outside the testing laboratory, testers usually need to carry lightweight, handheld measuring devices to the site for measurement. However, handheld measuring devices often need to be corrected for the position of the object to be tested, such as by aligning the detection probe to be perpendicular to the surface of the object to be tested. This is a challenge for large objects because the object to be tested cannot be removed for position correction. Therefore, testers need to find a way to fix the handheld measuring device on the object to be tested, but this is not only time-consuming and labor-intensive, but also requires additional measuring instruments to confirm whether the position correction is accurate.

[0003] Taking the detection of surface roughness as an example, the detection conditions include: (1) ensuring that the probe is perpendicular to the surface to be tested; (2) the probe cannot leave the surface of the object to be tested during the detection trajectory. These detection conditions make it difficult for the roughness tester to measure the surface of curved objects, and for large curved objects, the complexity of position correction needs to be considered. These difficulties make surface roughness detection in the workplace quite challenging.

[0004] In view of this, solving the current situation where it is difficult to perform inspections in the workplace has become a problem that needs to be solved in this technical field. At present, it is necessary to find a new method or device to overcome these difficulties so that inspectors can more easily perform accurate surface inspections in the workplace. Such a solution will be of great significance to improving work efficiency and ensuring inspection accuracy. Summary of the invention

[0010] The fixing fixture also includes: two limit slides and a range detection member. The two limit slides are located on the top surface of the extension part on both sides of the hollow part. The two ends of the range detection member are movably inserted into the two limit slides, and the bottom surface of the range detection member extends the detection block downward, and the free end of the detection block is located at the maximum detection depth position of the free end of the probe or within the maximum detection depth position. The range detection member moves horizontally in the extension part along the two limit slides and drives the detection block to move, and the distance when the detection block moves to the detection position closest to the probe is the effective detection range of the probe.

[0011] The extension part is also provided with a distance meter, which runs through the extension part downwards and is used to detect the distance between the probe and the surface of the object to be measured in a preset measurement track.

[0012] The fixing fixture further includes: two fixing members.

[0014] The fixing fixture also includes a fixing stand, which includes: a plurality of adjustment fixing blocks, a plurality of support members, a plurality of first locking elements, a plurality of supporting legs, and a plurality of second locking elements. Each adjustment fixing block is provided with a through hole, and each through hole corresponds to one of the plurality of fixing holes. Each supporting member is used to penetrate one of the plurality of adjustment fixing blocks, one of the plurality of through holes, and the fixing holes corresponding to the plurality of through holes, so as to support one of the plurality of adjustment fixing blocks to be arranged on the side plate. Each first locking element is used to fix the inclination angle of one of the plurality of adjustment fixing blocks. Each of the plurality of supporting legs penetrates one of the plurality of adjustment fixing blocks, and is used to fix the fixing fixture on the surface of the curved object to be measured, and each of the second locking elements is used to fix the length of one of the plurality of supporting legs.

The display unit is connected to the processing unit by signal, and is used to display the digital signal.

[0018] The present invention further provides an automated testing system, comprising the above-mentioned testing device and an automated device. The automated device is used to place a fixed fixture containing a measuring device on the surface of the object to be tested.

[0019] Compared with the prior art, the claimed effects of the present invention include: (1) Maintaining the measuring angle: Through the contact point at the bottom of the fixed fixture provided by the present invention, the measuring device installed on the fixed fixture can maintain a stable position on the surface of the object to be measured. (2) The position of the measuring device can be further stabilized by contacting the surface of the object to be measured by a fixing member (such as a magnet or adhesive) or a fixed tripod. (3) In some cases where it is necessary to measure the values ​​of a certain trajectory and to perform arithmetic averaging of the detection values, it is necessary to ensure that the probe can maintain contact with the surface of the object to be measured throughout the entire trajectory. The present invention uses a range detection member to provide pre-measurement confirmation based on the known measurement limit of the probe (in other words, a range detection member of corresponding specifications is used according to different measurement limits). (4) Through the fixed fixture provided by the present invention, the contact positioning surface of the probe is pre-positioned, and the effective detection range is confirmed by the range detection member and its detection block before actual measurement, which can avoid the problem of the probe hitting the surface of the object to be measured and being easily damaged and consumed during measurement.

DETAILED DESCRIPTION

[0034] The embodiments of the present invention will be further explained below with the help of the relevant drawings. As much as possible, the same reference numerals represent the same or similar components in the drawings and the specification. In the drawings, the shapes and thicknesses may be exaggerated for simplicity and convenience. It is understood that the components not specifically shown in the drawings or described in the specification are the forms known to those skilled in the art with ordinary skills in the art. Those skilled in the art can make various changes and modifications based on the content of the present invention.

[0035] See also Figure 1 , Figure 1: is a three-dimensional schematic diagram of a fixing fixture of an embodiment of the present invention. The fixing fixture 1 provided in this embodiment is suitable for stably leaning the measuring device against the surface of the object to be measured, and is particularly suitable for the object to be measured with a curved surface. The fixing fixture 1 includes a receiving portion 11, an extension portion 12, and a plurality of contactable points. At least one end of the receiving portion 11 is an opening, and the receiving portion 11 is used to carry the measuring device, and one end of the measuring device protrudes from the opening to the outside of the receiving portion 11. The extension portion 12 is formed by extending outward from the opening, and includes a hollow portion 13, which runs through the two corresponding top surfaces and the bottom surface of the extension portion 12, and the hollow portion 13 is used to accommodate one end of the measuring device. When the fixing fixture 1 is against the surface of the object to be measured, at least three of the plurality of contactable points on the bottom surface of the extension portion 12 are actual contact points, and the at least three contactable points form a positioning surface. Therefore, through the plurality of contactable points, the position of the measuring device can be maintained and maintained stable by hand pressure.

[0036] The fixture 1 further includes two grooves 14, which are disposed on the bottom surface of the extension portion 12. The two grooves 14 are used to lean against the surface of the object to be measured, thereby allowing one end of the measuring device to be located above the surface of the curved object to be measured. Furthermore, the two grooves 14 intersect with the bottom surface of the extension portion 12 and are adjacent to the hollow portion 13 to form the aforementioned plurality of contact points.

[0037] According to some embodiments, the operator can manually press the fixed fixture 1 on which the measuring device is mounted to place one end of the measuring device on the surface of the object to be measured. Due to differences in the appearance of the measuring device, the measuring device mounted on the fixed fixture 1 can be adjusted according to actual conditions, and the fixed fixture 1 is mainly used to stably place one end of the measuring device for receiving external information (such as a probe, lens or ruler) on the surface of the object to be measured.

[0038] According to some implementation aspects, the measuring device may be, for example, a roughness meter, a level meter, an arc meter, or a concentricity meter.

[0039] According to another embodiment, please refer to Figure 2 , Figure 2 2 is a three-dimensional schematic diagram of a roughness meter and a fixing fixture according to an embodiment of the present invention. The measuring device is a roughness meter 2, and in particular a handheld roughness meter 2. For ease of explanation, the roughness meter 2 is further divided into a body 21, a telescopic rod 22, and a probe 23. The telescopic rod 22 is arranged at one end of the body 21, and the probe 23 is arranged at one end of the telescopic rod, and the end point of the probe 23 faces the surface of the object to be measured. The telescopic rod 22 drives the probe 23 to move to measure the roughness of the surface of the curved object to be measured in a preset measurement track.

[0040] like Figure 3 , Figure 3It is a partially enlarged schematic diagram of the bottom surface of the roughness meter and the fixing fixture according to an embodiment of the present invention.

[0041] According to one embodiment, see Figure 3 The two grooves 14 intersect with the bottom surface of the extension portion 12 and the positions of the adjacent hollow portions 13 form at least three contact points ( Figure 3 Four contactable points P1, P2, P3, and P4 are shown, and at least three contactable points are used to contact the surface of the curved object to be tested.

[0042] According to another embodiment, at least three contactable points are formed by protrusions from the bottom surface of the extension portion 12 (not shown), and the surface of the curved object to be tested is contacted by the at least three contactable points.

[0043] According to some embodiments, when three contactable points (e.g., P1, P2, and P3) contact the surface of the curved object to be measured, a "triangular" positioning surface is formed, and the normal position between the positioning surface and the surface of the object to be measured is used as the starting point of the positioning probe 23 on the preset measurement track. The triangle can be, for example, an irregular triangle (scalenes), an isosceles triangle, a right triangle, or an equilateral triangle.

[0044] According to some other embodiments, when the four contact points (i.e., P1, P2, P3, and P4) contact the surface of the curved object to be measured, a "quadrilateral" positioning surface is formed, and the normal position between the positioning surface and the surface of the object to be measured is used as the starting point of the positioning probe 23 on the preset measurement track. The quadrilateral can be, for example, an irregular trapezoid, a rectangle, a square, a rhombus, a trapezoid, or a parallelogram.

[0045] In summary, according to this embodiment, only three contact points (such as P1, P2, and P3) are needed as actual contact points to form a positioning surface. More than three contact points (such as P1, P2, P3, and P4) can increase the stability of the fixture 1 on the object to be tested, that is, the more actual contact points, the better the stability.

[0046] In addition, when measuring the roughness of the surface of the object to be measured, the probe 23 of the roughness meter 2 not only moves along the X-axis on the surface according to the preset measurement track, but is also limited by the vertical measurement limit in the Z-axis direction. For the object to be measured with a large height difference on the surface, the probe 23 may be suspended in a part of the preset measurement track, resulting in measurement failure.

[0047] In view of this, please refer to Figure 4 , Figure 4It is a partial enlarged schematic diagram of the top surface of the fixed fixture of the embodiment of the present invention. According to another embodiment, the fixed fixture 1 also includes two limit slide grooves 15 and a range detection member 16. The two limit slide grooves 15 are located on the top surface of the extension portion 12 on both sides of the hollow portion 13. The two ends of the range detection member 16 are movably inserted in the two limit slide grooves 15, and the bottom surface of the range detection member 16 extends downwardly to the detection block 162.

[0048] Please refer to Figure 5 to Figure 6B . Figure 5 It is a partially enlarged perspective diagram of the top surface of the fixing fixture according to an embodiment of the present invention. Figure 6A to Figure 6B Schematic diagram of the relative positions of the probe and the detection block of an embodiment of the present invention. The free end of the detection block 162 is located at the maximum detection depth position of the free end of the probe 23 or within the maximum detection depth position, the range detection member 16 moves horizontally along the two limit slide grooves 15 in the extension portion 12, and drives the detection block 162 to move, and the distance when the detection block 162 moves to the detection position closest to the probe 23 is the effective detection range of the probe 23.

[0049] According to some embodiments, the probe 23 and the range detection member 16 can be used together or separately as needed. The range detection member 16 and its detection block 162 can be used to confirm the effective detection range (ER) before the actual measurement of the probe 23. Figure 6A to Figure 6B It is only to illustrate the relative position relationship between the probe 23 and the detection block 162. If they are used together, the shape of the range detection member 16 should be adjusted according to the shape of the detection device and the detection method to avoid blocking the operating space of the probe 23. If they are used alone, the probe 23 and the detection block 162 are not actually visible at the same time, so Figure 6A to Figure 6B The probe 23 in FIG. 5 is shown in a dotted frame.

[0050] For more details, please refer to Fig. 6A The detection block 162 approaches the surface 3A of the curved object to be tested through the two limiting slide grooves 15 until the free end (end point) of the detection block 162 is clamped by the surface of the curved object to be tested, so as to confirm that the area between the detection block 162 and the probe 23 is the effective detection range (ER).

[0051] Please refer to Figure 6B As mentioned above, the probe 23 moves in the X-axis direction according to the preset measurement track, and it is necessary to ensure that the movement of the probe 23 in the X-axis direction within the preset measurement track does not exceed the vertical measurement limit. Figure 6BFor example, the dotted box is the range formed by the moving distance of the probe 23 in the X-axis direction and the vertical measurement limit in the Z-axis direction. Therefore, the curvature change of the curved surface 3A of the object to be measured does not exceed the dotted box, so that the probe 23 can completely collect the roughness values ​​within the preset measurement track. On the other hand, the end of the curved surface 3B of the object to be measured has exceeded the dotted box, so that the probe 23 cannot completely collect the roughness values ​​within the preset measurement track.

[0052] According to another embodiment, the extension portion 12 is further provided with a distance meter (not shown), which passes through the extension portion 12 downwards and is used to detect the distance between the probe 23 and the surface of the object to be measured in a preset measurement track. Specifically, the distance meter can be, for example, a laser distance meter, and the position of the probe 23 in the Z-axis direction (e.g., three-dimensional coordinates) is set in advance to measure the distance between the probe 23 and the surface of the object to be measured within the range of the preset measurement track, so as to prevent the distance between the probe 23 and the surface of the object to be measured from exceeding the vertical measurement limit of the probe 23.

[0053] According to another embodiment, please also refer to Figure 3 , Figure 7 , Figure 7 The top surface of the roughness tester and the fixture 1 is a partially enlarged perspective diagram of the embodiment of the present invention. The fixture 1 also includes two fixing members 17. The two fixing members 17 are arranged on the extension portion 12, and the two fixing members 17 respectively penetrate the central position of the two grooves 14 to provide additional fixing force to place at least three contact points (for example, P1, P2, and P3) against the surface of the object to be measured.

[0054] Please refer to Figure 8 , Figure 8 Schematic diagram (1) of the use status of the roughness meter and the fixing fixture according to the embodiment of the present invention. Figure 8 It can be seen that the fixing fixture 1 is fixed on the surface of the object to be tested 3 by two fixing members 17 .

[0055] According to some embodiments, the fixing member 17 may be a magnet, so that the additional fixing force is a magnetic force, so as to utilize the magnetic force generated by the magnet to adsorb the surface of the object to be measured, thereby keeping the position of the measuring device stable.

[0056] According to some embodiments, an additional sticky substance may be added to one end of the fixing member 17 that is connected to the surface of the object to be measured, so that the additional fixing force is an adhesive force. The sticky substance may be, for example, clay or a reusable double-sided adhesive tape. When the surface of the object to be measured is non-magnetic, the position of the measuring device may be maintained by adhesion and stability.

[0057] According to another embodiment, see Figure 1, the accommodating portion 11 also includes: two side panels 112 and a bottom panel 114. The two side panels 112 are arranged on both sides of the bottom panel 114, and the two side panels 112 have a plurality of fixing holes 112a. In addition, the fixing fixture 1 also includes a fixing stand 19, and the fixing stand 19 includes: a plurality of adjustment fixing blocks 191, a plurality of support members 192, a plurality of first locking elements 193, a plurality of support legs 194 and a plurality of second locking elements 195. Each adjustment fixing block 191 is provided with a through hole 191a, and each through hole 191a corresponds to one of the plurality of fixing holes 112a. Each support member 192 is used to penetrate one of the plurality of adjustment fixing blocks 191, one of the plurality of through holes 191a and the fixing holes corresponding to the plurality of through holes 191a, so as to support one of the plurality of adjustment fixing blocks to be arranged on the side panel 112a. Each first locking element 193 is used to fix the tilt angle of one of the plurality of adjusting fixing blocks 191. Each plurality of supporting legs 194 penetrates one of the plurality of adjusting fixing blocks 191 and is used to fix the fixture 1 on the surface of the curved object to be tested. Each second locking element 195 is used to fix the length of one of the plurality of supporting legs 194. Figure 1 In order to make the through hole 191 a visible, the support member 192 is not drawn in some fixed tripods 19.

[0058] Please refer to Fig. 9 , Fig. 9 This is a partial enlarged view of the fixed tripod. Fig. 9 It can be seen that the fixed bracket 19 is disposed on the side plate 112 of the accommodating portion 11 .

[0059] According to some implementations, each of the plurality of first locking elements 193 passes through one of the plurality of adjusting and fixing blocks 191 , and adjusts and fixes the tilt angle of one of the plurality of adjusting and fixing blocks 191 by contacting one of the two side plates 112 .

[0060] According to some embodiments, each of the plurality of second locking elements 195 penetrates into one of the plurality of adjustment fixing blocks 191 and contacts one of the plurality of support legs 194 to adjust and fix the length of one of the plurality of support legs 194, wherein the length refers to the distance between the adjustment fixing block 191 and the surface of the object to be measured.

[0061] Please refer to Fig.10 , Fig.10 Schematic diagram (2) of the use status of the roughness meter and the fixing fixture according to the embodiment of the present invention. Fig.10 It can be seen that the fixing fixture 1 is fixed on the surface of the object to be tested 3 by the fixing stand 19 .

[0062] In addition, in order to ensure that the probe 23 can actually measure the target position (TA) on the object to be measured, the present invention further provides a plurality of marking lines as a basis for locating the target position (TA).

[0063] According to another embodiment, please also refer to Figure 4 , Fig.10 The surface of the extension portion 12 also includes a first positioning mark 181, a second positioning mark 182 and a third positioning mark 183. The first positioning mark 181 and the second positioning mark 182 are respectively on the top surface of the extension portion 12, parallel to the line formed by the bottom center position of the two grooves 14, and the center line of the extension portion 12 ( Figure 4 The dotted line of the extension portion 12 extends to the left and right edges and vertically borders the hollow portion 13, and the third positioning mark line 183 is formed by the center of the end point of the extension portion 12 and vertically borders the hollow portion 13. Fig.10 It can be seen that the intersection of the first positioning mark 181, the second positioning mark 182 and the third positioning mark 183 extending to the hollow part 13 is the position of the target position (TA). Not only can it be used as a basis for positioning, but also because the first positioning mark 181 and the second positioning mark 182 are respectively extended upward from the center of the bottom of the two grooves 14, it can ensure that the groove 14 is close to the surface of the object to be tested, so that the probe 23 can be stably close to the target position (TA). Fig.10 In order to make the target position (TA) visible, the probe 23 is not drawn.

According to another embodiment, the present invention also provides a detection device 4, including the above-mentioned fixed fixture 1, a processing unit 42 and a display unit 44. The processing unit 42 is connected to the measuring device 2 by a signal, and is used to receive the analog signal of the physical quantity of the surface of the object to be measured by the measuring device 2 installed on the fixed fixture 1, and convert the analog signal into a digital signal. The display unit 44 is connected to the processing unit 42 by a signal, and is used to display the digital signal.

[0065] According to some implementations, the physical quantity may be, for example, roughness, temperature, humidity, electrical conductivity, or any physical property that can be measured on the surface of the object to be tested.
