[0042] In order to make the technical content disclosed in this application more detailed and complete, reference may be made to the following specific embodiments of the present utility model in conjunction with the accompanying drawings. However, those of ordinary skill in the art should understand that the embodiments provided below are not used to limit the scope covered by the present utility model. In addition, the drawings are only schematically illustrated and are not drawn according to their original sizes.

[0043] The following further describes in detail the specific implementation manners of various aspects of the present utility model with reference to the accompanying drawings.

[0044] Embodiment 1:

[0045] This embodiment provides a mobile measurement device 5 for measuring the dimensions of automobile bodies and parts. Please refer to Figure 3 , Figure 4, the mobile measuring device 5 includes a base 51, a support member 52 fixed to the base 51, and a connecting member 53. Among them, the base 51 is used to fix the mobile measuring device 5 to the working plane 3; the support member 52 is used to support the product under test 4, that is, to fix the product under test 4 to the mobile measuring device 5; the support member 52 is fixed to the base 51 through the connecting member 53. Specifically, the working plane 3 is the working plane of a three-coordinate measuring instrument. During measurement, the product under test 4 is fixed to the mobile measuring device 5, the mobile measuring device 5 is fixed to the working plane 3, and then the three-coordinate measuring instrument is used to measure the dimensions of the product under test 4.

[0046] In this embodiment, the base 51 includes a magnetic attraction member 511 and a control switch 512. It is fixed to the working plane 3 through the magnetic attraction member 511, and the magnetic force of the magnetic attraction member 511 is turned on or off through the control switch 512. Specifically, the control switch 512 is a control button. In other embodiments of the present invention, other components capable of realizing the switch function can also be used. Specifically, the magnetic attraction member 511 includes a magnet. When the magnet rotates, the direction of its magnetic field can be changed, thereby controlling the adsorption capacity of the base 51. Specifically, when the control switch 512 is rotated clockwise to the ON position, the magnet is controlled to rotate to the position where the magnetic force is turned on, that is, the magnetic force of the magnetic attraction member 511 is turned on; when the control switch 512 is rotated counterclockwise to the OFF position, the magnet is controlled to rotate to the position where the magnetic force is turned off, that is, the magnetic force of the magnetic attraction member 511 is turned off.

[0047] Specifically, the working plane 3 is made of a metal material, and the magnetic attraction member 511 can be fixed to the working plane 3 through magnetic attraction. In the prior art, since the screw locking method needs to be used, a special base plate is required to fix the screw. Compared with the prior art, the magnetic attraction locking method is adopted in this embodiment, and the fixing position of the mobile measuring device 5 can be flexibly selected without using a special base plate, which is more convenient and flexible to use.

[0048] In this embodiment, the connecting component 53 includes a first connecting block 531 and a second connecting block 532. The supporting component 52 includes a supporting rod 521 and a height adjusting component 522. The supporting rod 521 is used to support the product 4 to be measured, and the height adjusting component 522 is used to adjust the height of the supporting rod 521. In the prior art, due to the inability to flexibly select the position of the mobile measuring device, there will be certain errors in the X and Y directions. Therefore, it is necessary to set up a front-back direction adjusting component and a rotation direction adjusting component to adjust the position of the product 4 to be measured in the X and Y directions. Compared with the prior art, in this embodiment, the position of the mobile measuring device 5 on the working plane 3 can be flexibly selected, and there is no need to set up other components to adjust the position of the product 4 to be measured in the X and Y directions. Therefore, the structure is simpler and the cost is lower.

[0049] In this embodiment, the height adjusting component 522 includes a third connecting block 5221 and a rotating screw 5222. The third connecting block 5221 is provided with a threaded hole 5223, and the first connecting block 531 is provided with a through hole 5311. The first connecting block 531 is arranged in the horizontal direction, the second connecting block 532 is arranged in the vertical direction. One end of the first connecting block 531 is connected to the supporting component 52, and the other end is fixed to one end of the second connecting block 532. The other end of the second connecting block 532 is fixed to the base 51.

[0050] In this embodiment, the supporting rod 521 is inserted vertically into the through hole 5311 of the first connecting block 531. The supporting rod 521 can slide in the through hole 5311. The rotating screw 5222 is placed in the threaded hole 5223. The rotating screw 5222 contacts one end of the supporting rod 521 through the threaded hole 5223. Specifically, the bottom end of the supporting rod 521 contacts the upper threaded end of the rotating screw 5222. By rotating the rotating screw 5222, the height of the supporting rod 521 is adjusted. Specifically, when the rotating screw 5222 rotates, the threaded end of the rotating screw 5222 moves up and down, thereby pushing the supporting rod 521 to move up and down in the vertical direction. Specifically, generally at least three mobile measuring devices 5 need to be set up for actual measurement. The product 4 to be measured is placed on the supporting rod 521, and the height of the supporting rod 521 needs to be adjusted to adjust the product 4 to a horizontal state to improve the measurement accuracy.

[0051] In this embodiment, the first connecting block 531, the second connecting block 532, and the third connecting block 5221 are all detachably connected. In this embodiment, the first connecting block 531 and the third connecting block 5221 are both provided with screw holes, and the first connecting block 531 and the third connecting block 5221 are fixed and locked by screws through the screw holes. In other embodiments of the present invention, other detachable connection methods may also be used.

[0052] In this embodiment, the support member 52 and the base 51 are detachably connected. Specifically, the base 51 includes a fourth connecting block 513, and the second connecting block 532 and the fourth connecting block 513 are connected by screws. In other embodiments of the present invention, other detachable connection methods may also be used.

[0053] Embodiment 2:

[0054] This embodiment provides a mobile measurement system. Please refer to Figure 3 、 Figure 4 , the mobile measurement system includes a working plane 3 and four mobile measurement devices 5 as described in Embodiment 1. In other embodiments of the present invention, other numbers of mobile measurement devices may be selected according to actual situations.

[0055] In this embodiment, the working plane 3 is made of metal. The mobile measuring device 5 includes a base 51, a supporting member 52 fixed to the base 51, and a connecting member 53. Among them, the base 51 is used to fix the mobile measuring device 5 to the working plane 3; the supporting member 52 is used to support the product under test 4, that is, to fix the product under test 4 to the mobile measuring device 5; the supporting member 52 is fixed to the base 51 through the connecting member 53. The base 51 includes a magnetic attraction member 511 and a control switch 512, and is fixed to the working plane 3 through the magnetic attraction member 511, and the magnetic force of the magnetic attraction member 511 is turned on or off through the control switch 512. Specifically, the magnetic attraction member 511 includes a cylinder, and a long strip of permanent magnet or constant magnetic magnet is placed in the middle of the cylinder. A soft magnetic material is provided at the bottom of the base 51, and the soft magnetic material is easily magnetized and demagnetized under a weak magnetic field. Specifically, by rotating the magnet through the control switch 512, when the two poles (N or S) of the magnet are in the vertical direction, that is, when the N pole or S pole of the magnet faces the soft magnetic material, the soft magnetic material is magnetized and has strong magnetism in the vertical direction. At this time, the base 51 generates a magnetic attraction force to fix the mobile device 5 to the working plane 3. When the two poles of the magnet are in the horizontal direction, that is, when the N pole and the S pole face the soft magnetic material, since there is only extremely small magnetism in the middle of the long strip magnet, the soft magnetic material will not be magnetized. At this time, there is almost no magnetic force on the base 51, and the mobile device 5 can be conveniently removed from the working plane 3.

[0056] Embodiment Three:

[0057] To further illustrate the technical solution of the present invention, this embodiment details the use process of the mobile measurement system described in Embodiment Two. The use steps are as follows:

[0059] (2) Turn off the magnetic attraction member 511 through the control switch 512, and adjust the mobile measuring device 5 to a suitable position, that is, complete the adjustment in the X and Y directions;

[0060] (3) Turn on the magnetic attraction member 511 through the control switch 512, and fix the mobile measuring device 5 to the working plane 3 through the magnetic attraction force;

[0061] (4) Place the product under test 4 on the support rod 521;

[0062] (5) Adjust the height of the support rod 521 by rotating the screw 5222 to adjust the product under test 4 to a horizontal state.

[0063] (6) Use a coordinate measuring machine to measure the dimensions of the product 4 to be measured.

[0064] The mobile measuring device of the present utility model includes a base and a support member fixed to the base. The base includes a magnetic attraction member and is fixed to the working plane through the magnetic attraction member. The present utility model adopts a fixed manner of magnetic attraction to realize the rapid disassembly of the mobile measuring device on the working plane, and the position of the mobile measuring device can be flexibly adjusted to adapt to different specifications of the product to be measured, which can reduce the development cost and reduce the use space.
