[0002] As we all know, the three-dimensional measuring machine can accurately measure the size, angle and other parameters of various workpieces (such as threaded parts). Through its high-precision probe system, the three-dimensional measuring machine can accurately measure the size of the workpiece in three-dimensional space.

[0003] However, the inventors have found that in the actual measurement process, when using a plane L-shaped measuring fixture to assist the three-dimensional measuring instrument (such as Figure 1 When measuring a lens barrel (as shown), it's generally necessary to wipe the surface of the L-shaped measuring jig clean before measurement and secure the lens barrel to the jig's panel with glue or double-sided tape. This makes it difficult to ensure the parallelism and perpendicularity of the lens barrel attached to the jig's panel, and can result in discrepancies in subsequent measurements using a 3D measuring instrument.

[0004] At the same time, based on this traditional method, once multiple lens barrel products need to be measured simultaneously, manpower is often required to arrange the multiple lens barrel products in sequence and stick them on the surface of the auxiliary measuring fixture. This can easily lead to uneven spacing between the lens barrel products, and cause the three-dimensional measuring instrument to calibrate and take points when measuring each lens barrel product, thereby affecting measurement efficiency and extending measurement time.

[0051] Please refer to Figure 2-8 , the first embodiment of the present utility model is:

[0052] An auxiliary measuring jig includes a mounting lock body 1 and a base plate 4.

[0053] like Figure 2 As shown, in this embodiment, there are two stations on the bottom plate 4, each station is equipped with a mounting lock body 1, and each station is respectively provided with five positioning columns 42 (see Figure 8 As shown in FIG. 1 , the lock body 1 is positioned and installed on the base plate 4 .

[0054] See also Figure 4-Figure 7 It can be seen that in this embodiment, the installation lock body 1 includes a first plate body 2 and a second plate body 3, and the first plate body 2 is detachably covered on the second plate body 3, and the first plate body 2 is provided with 12 circular through holes 21 arranged in an array, and these circular through holes 21 are distributed in three rows and four columns; wherein, the circular through holes 21 include a first circular hole portion 211 and a second circular hole portion 212, the first circular hole portion 211 and the second circular hole portion 212 are connected to each other, and the diameter of the first circular hole portion 211 is greater than the diameter of the second circular hole portion 212; the first circular hole portion 211 is opened on the upper surface of the first plate body 2, and the above-mentioned second circular hole portion 212 is opened on the lower surface of the first plate body 2, and the inner wall of the second circular hole portion 212 is provided with an internal thread 22.

[0055] In this embodiment, in order to facilitate assembly, a groove 23 is provided on the lower surface of the first plate body 2, and a protrusion 31 is provided on the upper surface of the second plate body 3, so that when the above-mentioned first plate body 2 is covered on the second plate body 3, the groove 23 and the protrusion 31 match each other in a concave-convex manner; wherein, in order to fix the above-mentioned first plate body 2 and the second plate body 3 together after assembly, the above-mentioned first plate body 2 is provided with a plurality of first positioning through holes 24, and the second plate body 3 is provided with a plurality of second positioning through holes 32. At the same time, the above-mentioned plurality of first positioning through holes 24 and the plurality of second positioning through holes 32 are arranged correspondingly, so that the fixing screws 6 can be inserted into the first positioning through holes 24 and the second positioning through holes 32 to match and fix the first plate body 2 and the second plate body 3.

[0056] It should be noted that, in this embodiment, the diameters of the multiple first positioning through holes 24 on the above-mentioned first plate body 2 can be adjusted according to actual application requirements, and the diameters of the multiple first positioning through holes 24 can also be different. The present invention does not specifically limit their sizes.

[0057] Accordingly, in this embodiment, in order to effectively match the positioning column 42 on the above-mentioned base plate 4, the position of the installation lock body 1 on the base plate 4 is limited, the outer contour edge of the above-mentioned first plate body 2 can be specifically provided with five second positioning grooves 25, and the outer contour edge of the above-mentioned second plate body 3 can be specifically provided with five first positioning grooves 33, and the above-mentioned five second positioning grooves 25 are arranged in a one-to-one correspondence with the five first positioning grooves 33, so that the five positioning columns 42 can be respectively arranged in the first positioning groove 33 and the second positioning groove 25, that is, the positioning column 42 can extend in the vertical direction through the second plate body 3 and extend into the second positioning groove 25 of the first plate body 2.

[0060] After fixing the lens barrel 5 product, place the assembled mounting lock body 1 on the base plate 4. Note that when the mounting lock body 1 and the base plate 4 are combined, the positioning groove on the mounting lock body 1 must cooperate with the positioning column 42 on the base plate 4. In this way, there is no need to use a stylus to calibrate the plate surface of the mounting lock body 1 during subsequent measurements. When measuring multiple modules of the same product, all products are screwed into the first plate body 2 of the mounting lock body 1. Only one calibration point is required to measure all the lens barrel 5 products that need to be measured at one time, thereby increasing measurement speed, saving time, and improving work efficiency.

[0061] In summary, the auxiliary measuring fixture designed by the present invention can effectively assist the three-dimensional measuring instrument in automatically detecting the dimensional data of multiple lens barrels 5. It can not only reduce the detection error, but also improve the accuracy and efficiency of measurement. It has good promotion prospects and application value.
