[0039] Reference below Figure 1-Figure 5 The support assembly 100 according to the embodiment of the utility model is described. The support assembly 100 is used to support a workpiece. When in use, the support assembly 100 can be installed on a tooling, and the tooling can be a gauge or a bracket.

[0040] like Figure 1-Figure 5 As shown, the support assembly 100 of the tooling according to the embodiment of the utility model includes: a mounting seat 1; a mounting block 2, the mounting block 2 is fixedly mounted on the mounting seat 1 and is located on one side of the mounting seat 1; a support portion 3, the support portion 3 is used to support the workpiece, the support portion 3 is fixedly mounted on the mounting block 2, and along the arrangement direction of the mounting seat 1 and the mounting block 2, the position of the support portion 3 relative to the mounting block 2 is adjustable.

[0041] The support assembly 100 includes a mounting seat 1, a mounting block 2 and a support portion 3, wherein the mounting seat 1 can support the mounting block 2 and the support portion 3, thereby improving the structural stability of the mounting block 2 and the support portion 3. The mounting block 2 is fixed to the mounting seat 1, for example, the mounting block 2 can be fixed to the mounting seat 1 by bolts, or the mounting block 2 can be fixed to the mounting seat 1 by snap connection, but the present application is not limited thereto, and the mounting block 2 can also be fixed to the mounting seat 1 by other means, as long as the mounting block 2 is fixed to the mounting seat 1. The present application takes the mounting block 2 fixed to the mounting seat 1 by bolts as an example for explanation, and the bolt connection can improve the connection reliability between the mounting block 2 and the mounting seat 1, reduce the risk of separation between the mounting block 2 and the mounting seat 1, thereby improving the structural stability of the support assembly 100, and when the mounting block 2 is damaged, the bolt connection facilitates the operator to replace the mounting block 2, thereby improving the service life of the support assembly 100. The mounting block 2 is located on one side of the mounting base 1. As an embodiment of the present application, along the height direction of the support assembly 100, the mounting block 2 is located on the upper side of the mounting base 1 so that the mounting base 1 supports the mounting block 2 and improves the position stability of the mounting block 2.

[0042] The support portion 3 is used to support the workpiece. As an embodiment of the present application, the workpiece is in contact with the support portion 3 so that the support portion 3 supports the workpiece and improves the stability of the workpiece. The support portion 3 is fixed to the mounting block 2. As an embodiment of the present application, the support portion 3 can be screwed on the mounting block 2. Along the arrangement direction of the mounting seat 1 and the mounting block 2, the position of the support portion 3 relative to the mounting block 2 can be adjusted by screwing. Such a setting can change the height of the support assembly 100, so that the height of the support assembly 100 is adapted to the height of the workpiece, improve the fit between the support portion 3 and the workpiece, and thus improve the accuracy of the test results of the workpiece and the authenticity of the data.

[0043] As an embodiment of the present application. The mounting block 2 may be provided with a driving cylinder, and the support portion 3 is fixed to the driving cylinder, so that the support portion 3 is indirectly fixed to the mounting block 2 through the driving cylinder. By extending and retracting the driving portion of the driving cylinder, the relative position of the support portion 3 and the mounting block 2 can be adjusted. Compared with the conventional method of adjusting the support assembly 100 by adding or reducing gaskets, adjusting the support assembly 100 by adjusting the height of the support portion 3 can reduce the difficulty of adjusting the support assembly 100, save adjustment time, and thus improve the adjustment efficiency of the support assembly 100.

[0044] Specifically, along the height direction of the support assembly 100, the mounting block 2 is fixed to the upper side of the mounting seat 1 by bolts, and the support portion 3 is screwed to the mounting block 2 so that the support portion 3 is fixed on the mounting block 2. The support portion 3 is in contact with the workpiece so that the support portion 3 can support the workpiece. When the operator needs to inspect the workpiece, the stability of the workpiece can be improved by supporting the workpiece by the support portion 3, thereby improving the accuracy of the inspection result and the authenticity of the data of the workpiece. Along the arrangement direction of the mounting seat 1 and the mounting block 2, the position of the support portion 3 relative to the mounting block 2 is adjustable. During the transportation, movement or use of the support assembly 100, the position of the support portion 3 may change, resulting in the position of the support portion 3 not being in the theoretical position. As an embodiment of the present application, the theoretical position of the support portion 3 may be a position adapted to the position of the workpiece.

[0045] When the height of the support part 3 is higher than the theoretical position, the support part 3 is rotated to adjust the height of the support assembly 100 to be lowered. When the height of the support part 3 is lower than the theoretical position, the support part 3 is rotated in the opposite direction to adjust the height of the support assembly 100 to be raised, so that the height of the support assembly 100 is in the theoretical position, thereby making the height of the support part 3 match the height of the workpiece, reducing the risk of damage to the workpiece due to poor fit between the support part 3 and the workpiece, and further improving the accuracy of the test results and the authenticity of the data.

[0046] Thus, by providing the support portion 3 and making the position of the support portion 3 relative to the mounting block 2 adjustable, the height of the support assembly 100 can be changed, so that the height of the support assembly 100 is adapted to the height of the workpiece, and the fit between the support portion 3 and the workpiece is improved, thereby improving the accuracy of the test results of the workpiece and the authenticity of the data. Moreover, compared with the traditional method of adjusting the support assembly 100 by adding or reducing gaskets, adjusting the support portion 3 can reduce the difficulty of adjusting the support assembly 100, save adjustment time, and thus improve the adjustment efficiency of the support assembly 100.

[0047] In some embodiments of the present invention, Figure 1-Figure 4 As shown, the support portion 3 includes a support rod 31 for supporting the workpiece, the outer peripheral wall of the support rod 31 is formed with an external thread 312, the mounting block 2 is formed with a first mounting hole 21, the axial direction of the first mounting hole 21 is the same as the arrangement direction of the mounting seat 1 and the mounting block 2, the inner peripheral wall of the first mounting hole 21 is formed with a first internal thread 211, part of the support rod 31 is assembled in the first mounting hole 21, and the external thread 312 and the first internal thread 211 are assembled together, and the position of the support portion 3 relative to the mounting block 2 is adjusted by rotating the support rod 31.

[0048] The support portion 3 may include a support rod 31, the workpiece abuts against the support rod 31 so that the support rod 31 supports the workpiece, and the outer peripheral wall of the support rod 31 is formed with an external thread 312. The mounting block 2 is formed with a first mounting hole 21, the axial direction of the first mounting hole 21 is the same as the arrangement direction of the mounting seat 1 and the mounting block 2, and the inner peripheral wall size of the first mounting hole 21 is adapted to the outer peripheral wall size of the support rod 31. Further, the inner peripheral wall of the first mounting hole 21 is formed with a first internal thread 211 adapted to the external thread 312, and the external thread 312 is screwed with the first internal thread 211, so that part of the support rod 31 is assembled in the first mounting hole 21, and the other part of the support rod 31 is arranged outside the first mounting hole 21 for supporting the workpiece. The external thread 312 and the first internal thread 211 are assembled together, and the position of the support part 3 relative to the mounting block 2 can be adjusted by rotating the support rod 31. When the height of the workpiece is low, the support rod 31 is rotated to adjust the height of the support assembly 100 to be lowered. When the height of the workpiece is high, the support rod 31 is rotated in the opposite direction to adjust the height of the support assembly 100 to be raised, so that the height of the support assembly 100 is adapted to the height of the workpiece, thereby making it easy to adjust the position of the support rod 31.

[0049] In some embodiments of the present invention, Figure 1-Figure 4 As shown, a limiting boss 311 is formed on the outer peripheral wall of the support rod 31 . The limiting boss 311 is located outside the mounting block 2 . The limiting boss 311 is suitable for abutting against the outer surface of the mounting block 2 for limiting position.

[0050] The outer peripheral wall of the support rod 31 forms a limiting boss 311, which is used to limit the support rod 31. The limiting boss 311 and the support rod 31 can be connected by, but not limited to, integral molding, welding, etc. The limiting boss 311 is located outside the mounting block 2, and the limiting boss 311 abuts against the outer surface of the mounting block 2, so that the limiting boss 311 can limit the support rod 31, reduce the risk of over-rotation of the support rod 31 leading to over-assembly of the support rod 31 and the first mounting hole 21, and facilitate the support rod 31 to be smoothly rotated out of the first mounting hole 21, thereby improving the reliability of the height adjustment function of the support assembly 100.

[0051] In some embodiments of the present invention, Figure 1-Figure 4 As shown, the support assembly 100 may further include: a locking member 4, which is used to lock the support portion 3 when the position adjustment of the support portion 3 relative to the mounting block 2 is completed.

[0052] The support assembly 100 may further include a locking member 4, which is used to lock the support portion 3. The locking member 4 may be, but is not limited to, configured as a locking nut. When the position adjustment of the support portion 3 relative to the mounting block 2 is completed, the locking member 4 is assembled with the support rod 31 so that the locking member 4 locks the support portion 3. The locking member 4 may also be configured as a locking clip, which may be provided on the mounting block 2. When the position adjustment of the support portion 3 relative to the mounting block 2 is completed, the locking clip clamps the support portion 3 to prevent the support portion 3 from rotating, so that the locking member 4 locks the support portion 3. By providing the locking member 4, the risk of the position movement of the support portion 3 relative to the mounting block 2 due to the heavy weight of the workpiece is reduced, which is conducive to improving the position stability of the support portion 3 relative to the mounting block 2, thereby making the height of the support assembly 100 stable, and further making the support portion 3 reliably abut against the workpiece, thereby improving the accuracy of the test results of the workpiece and the authenticity of the data.

[0053] In some embodiments of the present invention, Figure 4 As shown, the locking member 4 is annular to define an assembly hole 41, the locking member 4 is located outside the mounting block 2, the inner peripheral wall of the assembly hole 41 is formed with a second internal thread, the support rod 31 is passed through the assembly hole 41, and the external thread 312 and the second internal thread are assembled together.

[0054] The locking member 4 can be constructed in a ring shape to define an assembly hole 41. The locking member 4 is located outside the mounting block 2. The locking member 4 can abut against the mounting block 2 to limit the movement of the support rod 31, thereby improving the position stability of the support portion 3. The inner peripheral wall of the assembly hole 41 is formed with a second internal thread that matches the external thread 312. The support rod 31 is inserted into the assembly hole 41, and the external thread 312 and the second internal thread are assembled in cooperation. The relative position of the locking member 4 and the support rod 31 can be changed by rotating the locking member 4. When the locking member 4 abuts against the mounting block 2, the locking member 4 stops rotating. At this time, the locking member 4 can lock the support rod 31, thereby reducing the risk of the support rod 31 loosening.

[0055] In some embodiments of the present invention, Figure 1-Figure 4 As shown, the cross section of the support rod 31 is circular.

[0056] Among them, compared with the cross-section of the support rod 31 being set to a quadrilateral shape, the cross-section of the support rod 31 being set to a circular shape can reduce the cross-sectional area of ​​the support rod 31, thereby reducing the contact area between the support portion 3 and the workpiece, which is beneficial to reducing the risk of poor fitting between the support portion 3 and the workpiece, thereby reducing the risk of point contact or line contact between the support portion 3 and the workpiece, and further improving the accuracy of the inspection results of the workpiece and the authenticity of the data.

[0057] In some embodiments of the present invention, Figure 1-Figure 2As shown, the mounting block 2 includes a first body 22 and a second body 23 connected to each other, the support portion 3 is mounted on the first body 22 , and the second body 23 is fixedly connected to the mounting seat 1 .

[0058] Among them, the mounting block 2 includes a first body 22 and a second body 23, and the first body 22 and the second body 23 are connected. For example, the first body 22 and the second body 23 can be integrally formed, and the first body 22 and the second body 23 can also be welded and connected, but the present application is not limited to this. The first body 22 and the second body 23 can also be connected in other ways, as long as the first body 22 and the second body 23 are connected. The present application takes the integral forming of the first body 22 and the second body 23 as an example for explanation. The integral forming can improve the connection reliability of the first body 22 and the second body 23, reduce the risk of separation of the first body 22 and the second body 23, thereby improving the structural stability of the support assembly 100.

[0059] The support portion 3 is mounted on the first body 22. As some embodiments of the present application, the support portion 3 is screwed to the first body 22, and the second body 23 is fixedly connected to the mounting seat 1. As some embodiments of the present application, the second body 23 is connected to the mounting seat 1 by bolts, so that the support portion 3, the mounting block 2 and the mounting seat 1 are all connected. Therefore, by adjusting the relative position of the support portion 3 and the first body 22, the height of the support assembly 100 can be adjusted to make the height of the support assembly 100 match the height of the workpiece. By setting the first body 22 and the second body 23, the assembly position of the mounting block 2 and the mounting seat 1 and the assembly position of the mounting block 2 and the support portion 3 can be staggered, so as to avoid the assembly structure of the mounting block 2 and the mounting seat 1 from interfering with the support portion 3, thereby improving the working reliability of the support portion 3.

[0060] In some embodiments of the present invention, Figure 2 As shown, the second body 23 is formed with a second mounting hole 231 , and the mounting seat 1 is formed with a third mounting hole 11 corresponding to the second mounting hole 231 .

[0061] Among them, the second main body 23 is formed with a second mounting hole 231, and the mounting seat 1 is formed with a third mounting hole 11. The third mounting hole 11 is arranged corresponding to the second mounting hole 231. By passing a bolt through the second mounting hole 231 and screwing it with the third mounting hole 11 of the mounting seat 1, the second main body 23 and the mounting seat 1 can be connected by bolts, so that the mounting block 2 is fixed to the mounting seat 1. The mounting seat 1 provides support for the mounting block 2, which is beneficial to improving the stability of the mounting block 2, thereby further improving the structural stability of the support assembly 100.

[0062] In some embodiments of the present invention, Figure 2As shown, the second body 23 is formed with a first positioning portion 232 , and the mounting seat 1 is formed with a second positioning portion 12 matched with the first positioning portion 232 .

[0063] Among them, the second main body 23 is formed with a first positioning portion 232, and the mounting seat 1 is formed with a second positioning portion 12. The second positioning portion 12 is positioned and matched with the first positioning portion 232. As some embodiments of the present application, the first positioning portion 232 can be constructed as a positioning hole, and the second positioning portion 12 can be constructed as a positioning column. The positioning column is passed through the positioning hole so that the second positioning portion 12 is assembled with the first positioning portion 232, thereby achieving a positioning effect on the mounting block 2, facilitating accurate assembly of the mounting block 2 and the mounting seat 1, and improving the assembly accuracy and efficiency of the support assembly 100.

[0064] According to the tooling of the embodiment of the utility model, the support assembly 100 of the above embodiment is included. By setting the support part 3 and making the position of the support part 3 relative to the mounting block 2 adjustable, the height of the support assembly 100 can be quickly adjusted manually, so that the support part 3 is in the theoretical position, so that the height of the support assembly 100 is adapted to the height of the workpiece, and the fit between the support part 3 and the workpiece is improved, thereby improving the accuracy of the test result of the workpiece and the authenticity of the data. As an embodiment of the present application, the workpiece can be a vehicle side. The traditional support assembly 100 needs 50s of adjustment time to adjust the height, and the adjustment time and the detection time take 2-3 hours in total. Compared with the traditional method of adjusting the support assembly 100 by adding or reducing gaskets, the present application can reduce the difficulty of adjusting the support assembly 100 by adjusting the support part 3. The height adjustment time of the support assembly 100 is about 10s, and the adjustment time and the detection time take 0.5-1 hours in total, saving the adjustment time and the detection time, thereby improving the adjustment efficiency of the support assembly 100.
