[0031] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following is for reference. Figures 1-4 A mounting apparatus 100 for a welded strain gauge 200 according to an embodiment of the present invention is described.

[0033] According to an embodiment of the present invention, a mounting device 100 for a welded strain gauge 200 is provided, wherein the welded strain gauge 200 is adapted to be fixed to the object being measured, such as... Figures 1-4 As shown, the mounting device 100 may include a fixing mechanism 10 and a mounting mechanism 20. The fixing mechanism 10 is adapted to be fixed to the surface of the object being measured. The mounting mechanism 20 is movably disposed on the fixing mechanism 10 along a first direction and is also rotatably disposed on the fixing mechanism 10 about the first direction. The mounting mechanism 20 has a mounting portion 23 for mounting a welded strain gauge 200. The mounting portion 23 is movable along a second direction and is configured to thermally engage with the welded strain gauge 200. The first direction and the second direction intersect.

[0034] It should be noted that existing welded strain gauges consist of a strain gauge body and a metal base. Before being welded to the object being measured, the metal base is typically fixed to the object by adhesive bonding. During the welding process, due to the poor stability of adhesive bonding, the welded strain gauge may shift relative to the object. Furthermore, the heat generated during welding may be conducted to the strain gauge body through the metal base, thus affecting the testing accuracy or damaging the welded strain gauge.

[0035] Based on this, this application provides an installation device 100 for a welded strain gauge 200, which is suitable for being fixed to the object being measured by welding. As an example, the welded strain gauge 200 may include a strain gauge body 210 and a metal base 220. The metal base 220 may extend circumferentially around the strain gauge body 210 and may be arranged around the strain gauge body 210 circumferentially. The metal base 220 may be welded to the object being measured, thereby achieving the effect of welding the welded strain gauge 200 to the object being measured. The installation device 100 may include a fixing mechanism 10 and an installation mechanism 20. The fixing mechanism 10 is suitable for being fixed to the surface of the object being measured. As an example, the fixing mechanism 10 may be welded to the object being measured. As another example, the fixing mechanism 10 may abut against and limit the movement of the surface of the object being measured.

[0036] The mounting mechanism 20 is movably disposed on the fixed mechanism 10 along the first direction, and the mounting mechanism 20 is also rotatably disposed on the fixed mechanism 10 about the first direction, which facilitates the adjustment of the relative positions of the mounting mechanism 20 and the fixed mechanism 10 along and about the first direction. When the mounting device 100 is as follows... Figure 1 When setting the direction, the first direction can be... Figure 1 The mounting mechanism 20 may have a mounting portion 23, which allows for adjustment of the relative position of the mounting portion 23 and the fixing mechanism 10 along and around the first direction. The mounting portion 23 is movable along a second direction, which facilitates adjustment of the relative position of the mounting portion 23 and the fixing mechanism 10 along the second direction. The mounting portion 23 can be used to mount the welded strain gauge 200. The mounting portion 23 can be bonded to the welded strain gauge 200, and the mounting portion 23 can drive the welded strain gauge 200 to move synchronously, thereby achieving adjustment of the relative position of the welded strain gauge 200 and the measured object. This facilitates the installation of the welded strain gauge 200 at a specified installation position on the measured object, and facilitates the positioning and installation of the welded strain gauge 200.

[0037] The fixing mechanism 10 can be used to fix and support the mounting mechanism 20. The welded strain gauge 200 can be mounted on the mounting mechanism 20, and the fixing mechanism 10 can be fixed to the surface of the object being measured. This helps to reduce the probability of displacement of the welded strain gauge 200 relative to the object being measured when the welded strain gauge 200 is welded to the object being measured, and helps to improve the stability and reliability of the welded strain gauge 200 when it is installed on the object being measured. When the mounting device 100 is as follows... Figure 1 When setting the direction, the second direction can be... Figure 1 In the Y direction, the first direction can intersect with the second direction.

[0038] When the welded strain gauge 200 is welded to the object being measured, the heat generated during the welding process can be transferred to the welded strain gauge 200. The mounting part 23 can be thermally connected with the welded strain gauge 200. The mounting part 23 can absorb and dissipate the heat on the welded strain gauge 200, which helps to reduce the probability of the heat generated during the welding process affecting the test accuracy of the welded strain gauge 200 or damaging the welded strain gauge 200, and helps to improve the reliability of the welded strain gauge 200.

[0039] In this embodiment, by setting a fixing mechanism 10 for fixing the support mounting mechanism 20, the welded strain gauge 200 can be mounted on the mounting mechanism 20, and the fixing mechanism 10 can be fixed to the surface of the object being measured. This helps to reduce the probability of the welded strain gauge 200 shifting relative to the object being measured when the welded strain gauge 200 and the object being measured are welded together. This helps to improve the stability and reliability of the welded strain gauge 200 when it is installed on the object being measured. Furthermore, by setting a mounting part 23 to cooperate with the welded strain gauge 200 in thermal conduction, this helps to reduce the probability that the heat generated during the welding process between the welded strain gauge 200 and the object being measured will affect the testing accuracy of the welded strain gauge 200 or damage the welded strain gauge 200. This helps to improve the reliability of the welded strain gauge 200.

[0040] In some embodiments of the present invention, such as Figures 2-4 As shown, the mounting part 23 has a positioning structure 231 that is suitable for positioning and cooperating with the object being measured.

[0041] The mounting part 23 can be formed with a positioning structure 231, which is adapted to be positioned and engaged with the object being measured, so that the welded strain gauge 200 can be located at the designated installation position of the welded strain gauge 200 on the object being measured, which is beneficial to further realize the positioning and installation of the welded strain gauge 200. When the positioning structure 231 is positioned and engaged with the object being measured, the relative position of the mounting part 23 and the fixing mechanism 10 can be adjusted, so that the fixing mechanism 10 can be fixed to the surface of the object being measured. This is beneficial to further reduce the probability of the welded strain gauge 200 shifting relative to the object being measured when the welded strain gauge 200 is welded to the object being measured, and is beneficial to further improve the stability and reliability of the welded strain gauge 200 when installed on the object being measured. As an example, when the welded strain gauge 200 is used to measure the minute deformation of the object under stress, the welded strain gauge 200 should be installed at a specified installation position on the object. The surface of the specified installation position on the object may be marked, and the positioning structure 231 is adapted to be positioned and matched with the mark on the surface of the object, so that the welded strain gauge 200 can be installed at the specified installation position on the object.

[0042] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the mounting part 23 has multiple positioning notches 2311, and the positioning notches 2311 are positioning structures 231.

[0043] The mounting portion 23 may have multiple positioning notches 2311. Along the second direction, the positioning notches 2311 may be located on the side of the mounting portion 23 facing the welded strain gauge 200, and may extend along the second direction. The positioning notches 2311 are suitable for positioning and engaging with the object being measured, and may serve as positioning structures 231. By providing multiple positioning notches 2311, the reliability of the positioning structure 231 when engaging with the object being measured is improved. A reference line may be provided at the designated installation position of the welded strain gauge 200 on the surface of the object being measured. The multiple positioning notches 2311 may be correspondingly positioned with the corresponding reference line, further facilitating the positioning and installation of the welded strain gauge 200. The multiple positioning notches 2311 may be arranged sequentially along the circumference of the mounting portion 23, or spaced apart along the circumference of the mounting portion 23, which improves the accuracy of the positioning and installation of the welded strain gauge 200 and enhances its testing precision.

[0044] In some embodiments of the present invention, such as Figure 3 As shown, the mounting part 23 has a heat dissipation groove 232.

[0045] The mounting portion 23 may have a heat dissipation groove 232. The heat dissipation groove 232 may be constructed as a closed groove or have an open end. In this embodiment, the heat dissipation groove 232 having an open end is used as an example for explanation. The mounting portion 23 may have a heat dissipation groove 232 that opens toward the welded strain gauge 200, and the heat dissipation groove 232 may be recessed toward the interior of the mounting portion 23. When the welded strain gauge 200 is welded to the object being measured, the mounting portion 23 and the welded strain gauge 200 are thermally conductively connected, and the heat on the welded strain gauge 200 can be transferred to the mounting portion 23. By providing the mounting portion 23 with a heat dissipation groove 232, it is beneficial to improve the heat dissipation efficiency of the mounting portion 23, improve the heat dissipation effect of the mounting portion 23, further reduce the probability that the heat generated during the welding process between the welded strain gauge 200 and the object being measured will affect the testing accuracy of the welded strain gauge 200 or damage the welded strain gauge 200, and further improve the reliability of the welded strain gauge 200.

[0046] As an example, a cross-shaped reference line is provided at the designated installation position of the welded strain gauge 200 on the surface of the object being measured. The cross-shaped reference line may include two reference lines, which are perpendicular to each other. There can be three positioning notches 2311, which can be respectively located on the top wall and two side walls of the heat dissipation groove 232. The two positioning notches 2311 located on the side walls of the heat dissipation groove 232 can penetrate the corresponding side wall along its thickness direction, and can be respectively positioned to correspond to the two ends of one of the reference lines in the cross-shaped reference line. The positioning notch 2311 located on the top wall of the heat dissipation groove 232 can penetrate the top wall of the heat dissipation groove 232 along its thickness direction, and can be corresponding to one end of the other reference line in the cross-shaped reference line, thereby achieving positioning and engagement of multiple positioning notches 2311 with the object being measured.

[0047] In some embodiments of the present invention, such as Figure 1 As shown, the fixing mechanism 10 may include: a first fixing part 11 and a plurality of second fixing parts 12. The first fixing part 11 extends along a first direction, and the plurality of second fixing parts 12 are arranged sequentially along the first direction and are all fixed to the first fixing part 11. The second fixing parts 12 are adapted to be fixed to the object being measured, and the mounting mechanism 20 is mounted on the first fixing part 11.

[0048] The first fixing part 11 can extend along a first direction, and a plurality of second fixing parts 12 can be arranged sequentially along the first direction. As an example, both the first fixing part 11 and the second fixing part 12 can be constructed as rod structures. The plurality of second fixing parts 12 can be arranged opposite to each other and spaced apart along the first direction, and the plurality of second fixing parts 12 can all be fixed to the first fixing part 11. The second fixing parts 12 are suitable for being fixed to the object being measured. The second fixing parts 12 can be fixed to the object being measured by means of welding, suction cup adsorption, etc. The second fixing parts 12 can be connected between the first fixing part 11 and the object being measured, and the second fixing parts 12 can be used to support the first fixing part 11. The mounting mechanism 20 can be installed on the first fixed part 11. The mounting mechanism 20 can move relative to the first fixed part 11 along the first direction. The mounting mechanism 20 can also rotate relative to the first fixed part 11 around the first direction. When the second fixed part 12 is fixed to the object being measured, the mounting mechanism 20 moves relative to the first fixed part 11, which is beneficial to achieving the effect of the mounting part 23 moving relative to the object being measured. It is also beneficial to further achieve the effect of adjusting the relative position of the welded strain gauge 200 and the object being measured. Furthermore, it is beneficial to further enable the welded strain gauge 200 to be installed at the specified installation position on the object being measured.

[0049] As an example, a level 30 may be provided on the first fixing part 11. When the surface of the object being measured is tilted, the angle difference between the reading of the level 30 on the first fixing part 11 and the cross-shaped reference line on the surface of the object being measured needs to be within the specified range, which is beneficial to further improve the reliability of the welded strain gauge 200.

[0050] As an example, when the second fixing part 12 is constructed as a rod structure, a fixing suction cup 121 can be formed at the end of the second fixing part 12 connected to the object being measured. The second fixing part 12 can be adsorbed onto the surface of the object being measured by the fixing suction cup 121, which is beneficial to fix the second fixing part 12 to the object being measured. The fixing suction cup 121 also makes it easy to remove the second fixing part 12 from the surface of the object being measured, which is beneficial to improving the assembly and disassembly efficiency of the second fixing part 12 and the object being measured.

[0051] In some embodiments of the present invention, such as Figure 1 As shown, the second fixing part 12 is movably disposed on the first fixing part 11 along the first direction, and / or the second fixing part 12 is rotatable relative to the first fixing part 11 about the first direction.

[0052] The second fixing part 12 is movably disposed on the first fixing part 11 along the first direction, or the second fixing part 12 is rotatable relative to the first fixing part 11 about the first direction, or the second fixing part 12 is movably disposed on the first fixing part 11 along the first direction and is rotatable relative to the first fixing part 11 about the first direction. This embodiment of the application uses the example of the second fixing part 12 being movably disposed on the first fixing part 11 along the first direction and being rotatable relative to the first fixing part 11 about the first direction for explanation. The second fixing part 12 being movably disposed on the first fixing part 11 along the first direction means that the second fixing part 12 can move relative to the first fixing part 11 along the first direction. The second fixing part 12 is rotatable relative to the first fixing part 11 around the first direction, that is, the second fixing part 12 can rotate relative to the first fixing part 11 around the first fixing part 11. This is beneficial for adjusting the relative positions of the first fixing part 11 and the second fixing part 12 along and around the first direction, and for adjusting the relative positions of multiple second fixing parts 12. It is also beneficial for making the fixing mechanism 10 applicable to objects of different sizes, and for improving the practicality and versatility of the installation device 100.

[0053] In some embodiments of the present invention, such as Figure 1 As shown, the fixing mechanism 10 may further include: a plurality of first connecting seats 13, and a plurality of second fixing parts 12 corresponding one to one. The first connecting seat 13 includes a first connecting collar 131 and a second connecting collar 132 that are fixedly connected. The first connecting collar 131 forms a first sleeve hole 1311, and the second connecting collar 132 forms a second sleeve hole 1321. The central axis of the first sleeve hole 1311 is parallel to the first direction, and the central axis of the first sleeve hole 1311 and the central axis of the second sleeve hole 1321 are perpendicular. The first fixing part 11 passes through the first sleeve hole 1311, and the second fixing part 12 passes through the second sleeve hole 1321.

[0054] Multiple first connecting seats 13 can be correspondingly arranged with multiple second fixing parts 12. Each second fixing part 12 has a corresponding first connecting seat 13 for assembly. Each second fixing part 12 can be connected to a first fixing part 11 through a corresponding first connecting seat 13. The first connecting seat 13 may include a first connecting collar 131 and a second connecting collar 132 that are fixedly connected. The first connecting collar 131 and the second connecting collar 132 can be fixedly connected by welding, bolting, or other methods. The first connecting collar 131 may have a first sleeve hole 1311 that can penetrate the first connecting collar 131 along its axial direction. The first sleeve hole 1311 may be configured as a through hole. The second connecting collar 132 may have a second sleeve hole 1321 that can penetrate the second connecting collar 132 along its axial direction. The second sleeve hole 1321 may be configured as a through hole. The axial direction of the first connecting collar 131 can be parallel to the first direction, the central axis of the first sleeve hole 1311 can be parallel to the first direction, and the central axis of the first sleeve hole 1311 can be perpendicular to the central axis of the second sleeve hole 1321.

[0055] The first fixing part 11 can be inserted through the first sleeve hole 1311, and the second fixing part 12 can be inserted through the second sleeve hole 1321, thereby achieving the effect that the first fixing part 11 and the second fixing part 12 are perpendicular to each other. The first connecting collar 131 is movable relative to the first fixing part 11 along the first direction. The first connecting collar 131 can drive the second connecting collar 132 to move synchronously, and the second connecting collar 132 can drive the second fixing part 12 to move synchronously, thereby achieving the effect that the second fixing part 12 is movably disposed on the first fixing part 11 along the first direction. The first connecting collar 131 is rotatable relative to the first fixing part 11 around the first direction. The first connecting collar 131 can drive the second connecting collar 132 to rotate synchronously, and the second connecting collar 132 can drive the second fixing part 12 to rotate synchronously, thereby achieving the effect that the second fixing part 12 is rotatable relative to the first fixing part 11 around the first direction.

[0056] As an example, a first connecting collar 131 can be sleeved on a first fixing part 11. The first connecting collar 131 can extend circumferentially along the first fixing part 11. A first mounting hole 1312 and a second mounting hole can be formed at both ends of the first connecting collar 131, respectively. The first mounting hole 1312 and the second mounting hole can be correspondingly arranged and can communicate with each other. The first connecting collar 131 can have a first connecting member, which can pass through the first mounting hole 1312 and the second mounting hole and cooperate with a locking member to fix the first connecting collar 131 to the first fixing part 11, thereby fixing the second fixing part 12 to the first fixing part 11. By providing the first connecting collar 131, it is beneficial to achieve the effect of adjustable position of the second fixing part 12 relative to the first fixing part 11.

[0057] In some embodiments of the present invention, such as Figure 1 As shown, the mounting mechanism 20 may include a second connecting seat 21 and a mounting body 22. The second connecting seat 21 is movably disposed on the fixing mechanism 10 along the first direction, and the second connecting seat 21 is rotatable relative to the fixing mechanism 10 about the first direction. The mounting body 22 is fixed to the second connecting seat 21 and has a mounting part 23.

[0058] The second connecting seat 21 is movably disposed on the fixing mechanism 10 along the first direction, that is, the second connecting seat 21 is movably disposed on the first fixing part 11 along the first direction. The second connecting seat 21 can move relative to the first fixing part 11 along the first direction. Furthermore, the second connecting seat 21 is rotatable relative to the fixing mechanism 10 around the first direction, that is, the second connecting seat 21 is rotatable relative to the first fixing part 11 around the first direction. The second connecting seat 21 can rotate relative to the first fixing part 11 circumferentially, which is beneficial for adjusting the relative position of the first fixing part 11 and the second connecting seat 21 along and around the first direction. The mounting body 22 is fixed to the second connecting seat 21. The mounting body 22 has a mounting part 23, which is beneficial for adjusting the relative position of the mounting part 23 and the first fixing part 11 along and around the first direction. This is beneficial for further adjusting the relative position of the welded strain gauge 200 and the measured object, and for further positioning and installing the welded strain gauge 200.

[0059] In some embodiments of the present invention, such as Figure 1As shown, the second connecting seat 21 includes a third connecting collar 211 and a fourth connecting collar 212 that are fixedly connected. The third connecting collar 211 forms a third fitting hole 2111, and the fourth connecting collar 212 forms a fourth fitting hole 2121. The central axis of the third fitting hole 2111 is parallel to the first direction, and the central axis of the third fitting hole 2111 is perpendicular to the central axis of the fourth fitting hole 2121. The fixing mechanism 10 passes through the third fitting hole 2111, and the mounting body 22 passes through the fourth fitting hole 2121.

[0060] The second connecting seat 21 may include a third connecting collar 211 and a fourth connecting collar 212 that are fixedly connected. The third connecting collar 211 and the fourth connecting collar 212 may be fixedly connected by welding, bolting, or other methods. The third connecting collar 211 may have a third sleeve hole 2111, which can penetrate the third connecting collar 211 along its axial direction and may be configured as a through hole. The fourth connecting collar 212 may have a fourth sleeve hole 2121, which can penetrate the fourth connecting collar 212 along its axial direction and may be configured as a through hole. The axial direction of the third connecting collar 211 may be parallel to a first direction, the central axis of the third sleeve hole 2111 may be parallel to the first direction, and the central axis of the third sleeve hole 2111 may be perpendicular to the central axis of the fourth sleeve hole 2121.

[0061] The fixing mechanism 10 can be inserted through the third sleeve hole 2111, that is, the first fixing part 11 can be inserted through the third sleeve hole 2111, and the mounting body 22 can be inserted through the fourth sleeve hole 2121, thereby achieving the effect that the first fixing part 11 and the mounting body 22 are perpendicular to each other. The mounting body 22 can be arranged opposite to and spaced apart from multiple second fixing parts 12 along the first direction. The third connecting collar 211 is movable relative to the first fixing part 11 along the first direction. The third connecting collar 211 can drive the fourth connecting collar 212 to move synchronously, and the fourth connecting collar 212 can drive the mounting body 22 to move synchronously, thereby achieving the effect that the mounting body 22 is movably disposed on the first fixing part 11 along the first direction. The third connecting collar 211 is rotatable relative to the first fixing part 11 around the first direction. The third connecting collar 211 can drive the fourth connecting collar 212 to rotate synchronously, and the fourth connecting collar 212 can drive the mounting body 22 to rotate synchronously, thereby achieving the effect that the mounting body 22 is rotatable relative to the first fixing part 11 around the first direction.

[0062] As an example, a third connecting collar 211 can be fitted onto the first fixing part 11. The third connecting collar 211 can extend circumferentially along the first fixing part 11. A third mounting hole and a fourth mounting hole can be formed at both ends of the third connecting collar 211, respectively. The third and fourth mounting holes can be correspondingly arranged and can communicate with each other. The third connecting collar 211 can have a second connecting member 2112, which can pass through the third and fourth mounting holes and cooperate with the locking member, thereby fixing the third connecting collar 211 to the first fixing part 11, and thus fixing the mounting body 22 to the first fixing part 11. By providing the third connecting collar 211, it is beneficial to achieve an adjustable position of the mounting body 22 relative to the first fixing part 11.

[0063] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the mounting body 22 may include a mounting rod 221 and a movable component 222. The mounting rod 221 is fixed to the second connecting seat 21, and the movable component 222 is rotatably disposed on the mounting rod 221 about a first direction. The movable component 222 has a mounting part 23.

[0064] The mounting rod 221 can be fixed to the second connecting seat 21. The mounting rod 221 can pass through the fourth mounting hole 2121. The mounting rod 221 can move relative to the first fixing part 11 along the first direction, and the mounting rod 221 can rotate relative to the first fixing part 11 around the first direction. The movable component 222 can be provided on the mounting rod 221, and the mounting rod 221 can drive the movable component 222 to move synchronously. The movable component 222 is rotatably provided on the mounting rod 221 around the first direction, thereby adjusting the relative position of the movable component 222 and the mounting rod 221 around the first direction. The movable component 222 can have a mounting part 23, which is beneficial to further realize the effect of adjusting the relative position of the mounting part 23 and the fixing mechanism 10, which is beneficial to increase the range of adjustable relative position between the mounting part 23 and the measured object, and is beneficial to further realize the positioning and installation of the welded strain gauge 200.

[0065] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the mounting rod 221 is fixedly mounted on the mounting plate 223, and the movable component 222 also has a mounting base 2221. The mounting base 2221 is rotatably mounted on the mounting plate 223 about a first direction, and the mounting part 23 is movably mounted on the mounting base 2221 along a second direction.

[0066] Mounting rod 221 can be fixedly mounted on mounting plate 223. Mounting rod 221 can be fixedly connected to mounting plate 223 by welding, bonding, or other methods. Mounting base 2221 is rotatably mounted on mounting plate 223 about a first direction and can rotate on mounting plate 223 about the first direction. Mounting part 23 is movably mounted on mounting base 2221 about a second direction and can move on mounting base 2221 about the second direction. This facilitates adjusting the relative position of mounting part 23 and mounting plate 223 about the first direction and about the second direction, further increasing the range of adjustable relative position between mounting part 23 and the measured object, and further facilitating the positioning and installation of welded strain gauge 200.

[0067] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the mounting plate 223 has an arc-shaped guide opening 2231 that extends around a first direction, and the mounting base 2221 is provided with a guide block 22211, at least a portion of which is located in the arc-shaped guide opening 2231.

[0068] The mounting plate 223 may have an arc-shaped guide opening 2231. The arc-shaped guide opening 2231 may be constructed as a groove structure or as a through hole. In this embodiment, the arc-shaped guide opening 2231 is constructed as a through hole as an example. The arc-shaped guide opening 2231 may be constructed as a through hole, and the arc-shaped guide opening 2231 may penetrate the mounting plate 223 along the thickness direction of the mounting plate 223. The arc-shaped guide opening 2231 may extend around a first direction. Mounting base 2221 may be provided with guide block 22211. Guide block 22211 may be provided on the side of mounting base 2221 facing mounting plate 223. At least part of guide block 22211 may be provided in arc-shaped guide opening 2231. At least part of guide block 22211 may move along the extension direction of arc-shaped guide opening 2231. That is, guide block 22211 may drive mounting base 2221 to move around a first direction, thereby achieving the effect that mounting base 2221 is rotatably provided on mounting plate 223 around the first direction.

[0069] As an example, the mounting plate 223 can be constructed as a fan-shaped plate, so that the mounting plate 223 can be adapted to the arc-shaped guide opening 2231, which helps to reduce the material of the mounting plate 223 and reduce the cost of the mounting plate 223.

[0070] As an example, at least a portion of the guide block 22211 can pass through the arc-shaped guide opening 2231. The portion of the guide block 22211 extending out of the arc-shaped guide opening 2231 can have external threads, and the locking structure 22214 can have internal threads. The internal threads can be assembled with the external threads. The portion of the guide block 22211 extending out of the arc-shaped guide opening 2231 can be assembled with the locking structure 22214, which helps to reduce the probability of the guide block 22211 falling out of the arc-shaped guide opening 2231 and improves the reliability of the guide block 22211 when it moves within the arc-shaped guide opening 2231. Furthermore, when the guide block 22211 moves to the target position, the locking structure 22214 can be locked, so that the mounting plate 223 is sandwiched between the locking structure 22214 and a portion of the guide block 22211, which helps to lock the guide block 22211 at the target position.

[0071] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the active component 222 also has a first drive unit 2222, which is fixed to the mounting base 2221.

[0072] The active component 222 may also have a first drive unit 2222, which can be fixed to the mounting base 2221. The first drive unit 2222 can drive the mounting base 2221 to move the guide block 22211 within the arc-shaped guide opening 2231, which is beneficial for further realizing the effect of rotating the mounting base 2221 relative to the mounting plate 223 around the first direction, and for improving the convenience of adjusting the relative position of the mounting base 2221 and the mounting plate 223. As an example, the first drive unit 2222 can be constructed as a drive handle, which allows the operator to manually drive the mounting base 2221 to rotate around the first direction. As another example, the first drive unit 2222 can be constructed as an electric drive component, which is beneficial for improving the efficiency of the rotation of the mounting base 2221 around the first direction and for improving the automation level of the mounting device 100.

[0073] In some embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the active component 222 also has a second drive unit 2223, the mounting base 2221 has a guide rail 22212 and a slider 22213, the guide rail 22212 extends along a second direction, the slider 22213 is slidably disposed on the guide rail 22212 along the second direction and fixedly connected to the mounting unit 23, the second drive unit 2223 is disposed on the mounting base 2221, and the second drive unit 2223 is used to drive the slider 22213 to move.

[0074] The active component 222 may also have a second drive unit 2223. The mounting base 2221 may have a guide rail 22212 and a slider 22213. The guide rail 22212 may be bonded to the mounting base 2221, and the guide rail 22212 and the mounting base 2221 may be integrally formed, forming a single structure. The guide rail 22212 may extend along a second direction, and the slider 22213 may be assembled with the guide rail 22212. The slider 22213 is slidably disposed on the guide rail 22212 along the second direction and can slide relative to the guide rail 22212 along the second direction. The slider 22213 may be fixedly connected to the mounting part 23 by means of snap-fit, bonding, etc., which is beneficial to achieving the effect of the slider 22213 driving the mounting part 23 to move synchronously along the second direction. The second drive unit 2223 can be disposed on the mounting base 2221. The second drive unit 2223 can be disposed on the side of the slider 22213 away from the mounting part 23 along the second direction. The second drive unit 2223 can drive the slider 22213 to move, thereby further realizing the effect of the slider 22213 driving the mounting part 23 to move synchronously along the second direction. As an example, a level 30 can be provided on the slider 22213.

[0075] As an example, the second drive unit 2223 may include a first guide seat 22231 and a drive rod 22232. The first guide seat 22231 may be fixedly connected to the mounting base 2221. The first guide seat 22231 may have a guide hole, which can penetrate the first guide seat 22231 along a second direction. The inner wall of the guide hole may have an internal thread, and the outer peripheral wall of the drive rod 22232 may have an external thread. The internal thread and the external thread can be fitted together, thereby showing the effect of the drive rod 22232 rotating relative to the first guide seat 22231 and moving relative to the first guide seat 22231 along a second direction. The drive rod 22232 can move towards the slider 22213 along the second direction. The drive rod 22232 can abut against the slider 22213. After the drive rod 22232 abuts against the slider 22213, the drive rod 22232 can continue to move to drive the slider 22213 to move along the second direction.

[0076] As another example, the second drive unit 2223 may include a drive cylinder and a telescopic rod. The telescopic rod may be fixedly connected to the slider 22213. The drive cylinder may drive the telescopic rod to extend or retract in the second direction. When the telescopic rod extends or retracts in the second direction, the telescopic rod may drive the slider 22213 to move in the second direction, thereby further realizing the effect of the slider 22213 driving the mounting unit 23 to move synchronously in the second direction.

[0077] As an example, when the mounting device 100 is used to fix the welded strain gauge 200, firstly, a mark is made at the designated installation position of the welded strain gauge 200 on the surface of the object being measured, and a cross-shaped reference line is drawn at the corresponding position. Next, the welded strain gauge 200 and the mounting part 23 are bonded together. By adjusting the first connecting seat 13, the second connecting seat 21, the movable component 222, and the slider 22213, the positioning structure 231 can be positioned and engaged with the cross-shaped reference line on the surface of the object being measured, allowing the welded strain gauge 200 to be placed on the surface of the object being measured. Then, the first connecting seat 13, the second connecting seat 21, the movable component 222, and the slider 22213 are locked, making the welded strain gauge 200 relatively stationary with respect to the object being measured, and the welded connection between the welded strain gauge 200 and the object being measured is completed.

[0078] Other configurations and operations of the mounting apparatus 100 for the welded strain gauge 200 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
