Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem of directly measuring the three-dimensional dimensions of a workpiece, this invention provides a three-dimensional measuring instrument that can detect the three-dimensional coordinates of various positions on the workpiece, thereby measuring the dimensions of the workpiece in different dimensions.

[0020] It should be noted that the three-dimensional measuring instrument of this utility model is used for, but not limited to, detecting the three-dimensional dimensions of workpieces. For ease of explanation, this utility model will only use the application of the three-dimensional measuring instrument to detect the three-dimensional dimensions of workpieces as an example. The principle of the three-dimensional measuring instrument applied to other types of equipment is essentially the same as that applied to detect the three-dimensional dimensions of workpieces, and will not be described in detail here.

[0021] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of a three-dimensional measuring instrument according to an embodiment of the present invention. The three-dimensional measuring instrument includes an X-axis control component 100, a Y-axis control component 200, and a Z-axis control component 300. The X-axis control component 100 includes an X-axis 110 with an X-scale ruler (not shown) arranged axially. The Y-axis control component 200 includes a Y-axis 210 and a Y-connector 220. One end of the Y-connector 220 is slidably disposed on the X-axis 110, and the other end is slidably disposed on the Y-axis 210. The Y-axis 210 is perpendicular to the X-axis 110 and has a Y-scale ruler (not shown) arranged axially. The Z-axis control component 300 includes a Z-axis 310 and a Z-connector 320. One end of the Z-connector 320 is slidably disposed on either the X-axis 110 or the Y-axis 210, and the Z-axis 310 is slidably disposed on the other end of the Z-connector 320. The Z-axis 310 is perpendicular to both the X-axis 110 and the Y-axis 210 and has a Z-scale ruler (not shown) arranged axially.

[0022] In this embodiment, firstly, one end of the X-axis 110 is pressed against a reference surface. Then, the Y-connector 220 is slid to move the Y-axis 210 relative to the X-axis 110. Next, the Y-axis 210 is pulled relative to the Y-connector 220, causing the other end of the Y-axis 210 to press against another reference surface. Subsequently, the Z-connector 320 is slid to move the Z-axis 310 relative to the X-axis, and the Z-axis 310 is pulled relative to the Z-connector 320, causing one end of the Z-axis 310 to be aligned with the position to be measured. At this point, by referring to the X-scale (not shown in the figure), Y-scale (not shown in the figure), and Z-scale (not shown in the figure), the three-dimensional coordinates of the position to be measured can be obtained. Using the above-mentioned three-dimensional measuring instrument, the three-dimensional coordinates of each position to be measured on the workpiece can be detected, thereby directly obtaining the three-dimensional dimensions of the workpiece.

[0023] In some embodiments, the Y connector 220 has a first Y-guide hole 221 and a second Y-guide hole 222 at both ends. The first Y-guide hole 221 is movably fitted onto the X-axis 110, and the second Y-guide hole 222 is movably fitted onto the Y-axis 210. Because the first Y-guide hole 221 is movably fitted onto the X-axis 110, the Y connector 220 can slide along the Z-axis 310, thereby causing the Y-axis 210 to translate relative to the X-axis 110. Because the second Y-guide hole 222 is movably fitted onto the Y-axis 210, the Y-axis 210 can slide axially relative to the Y connector 220.

[0024] In some embodiments, the Y connector 220 has a first observation window 223 and a second observation window 224. The first observation window 223 is connected to the first Y guide hole 221 and contains a first pointer 225. The second observation window 224 is connected to the second Y guide hole 222 and contains a second pointer 226. An operator can observe the X-scale (not shown) through the first observation window 223, and the first pointer 225 can be used to compare with the X-scale (not shown) to reflect the axial coordinate of the X-axis 110. Similarly, the Y-scale (not shown) can be observed through the second observation window 224, and the second pointer 226 can be used to compare with the Y-scale (not shown) to reflect the axial coordinate of the Y-axis 210.

[0025] In some embodiments, the first Y-guide hole 221 has a first Y-guide groove 2211, and the X-axis 110 has an X-guide rail 112 that movably passes through the first Y-guide groove 2211 to restrict the rotation of the X-axis 110 relative to the Y-connector 220. The second Y-guide hole 222 has a second Y-guide groove 2221, and the Y-axis 210 has a Y-guide rail 212 that movably passes through the second Y-guide groove 2221 to restrict the rotation of the Y-axis 210 relative to the Y-connector 220. By restricting the rotation of the X-axis 110 relative to the Y-connector 220 and the Y-axis 210 relative to the Y-connector 220, it is ensured that the first scale is aligned with the first observation window 223 and the second scale is aligned with the second observation window 224.

[0026] In some embodiments, the Z-connector 320 includes a first Z-guide hole 321 and a second Z-guide hole 322. An X-axis 110 movably passes through the first Z-guide hole 321, and a Z-axis 310 movably passes through the second Z-guide hole 322. Because the X-axis 110 movably passes through the first Z-guide hole 321, the Z-connector 320 can drive the Z-axis 310 to slide relative to the X-axis 110. Furthermore, because the Z-axis 310 movably passes through the second Z-guide hole 322, it can slide axially relative to the Z-connector 320.

[0027] In some embodiments, the Z connector 320 has a third observation window 323 and a fourth observation window 324. The third observation window 323 is connected to the first Z guide hole 321 and contains a third pointer 325. The fourth observation window 324 is connected to the second Z guide hole 322 and contains a fourth pointer 326. An operator can observe the X-scale (not shown in the figure) through the third observation window 323, and the third pointer 325 can be used to compare with the X-scale (not shown in the figure) to reflect the axial coordinate of the X-axis 110. Similarly, the Z-scale (not shown in the figure) can be observed through the fourth observation window 324, and the fourth pointer 326 can be used to compare with the Z-scale (not shown in the figure) to reflect the axial coordinate of the Z-axis 310.

[0028] In some embodiments, the first Z-guide hole 321 has a first Z-guide groove 3211, which is sleeved on the X-guide rail 112 to restrict the rotation of the X-axis 110 relative to the Z-connector 320. The Z-axis 310 has the Z-guide rail 312. The second Z-guide hole 322 has a second Z-guide groove 3221, which is sleeved on the Z-guide rail 312 to restrict the rotation of the Z-axis 310 relative to the Z-connector 320.

[0029] By restricting the rotation of the X-axis 110 relative to the Y-connector 220 and restricting the rotation of the Y-axis 210 relative to the Y-connector 220, the third scale is aligned with the third observation window 323, and the fourth scale is aligned with the fourth observation window 324.

[0030] In some embodiments, an X-base 113 is mounted at each end of the X-axis 110 to facilitate alignment of the ends of the X-axis 110 with a reference surface.

[0031] In some embodiments, a Y-base 213 is mounted at each end of the Y-axis 210 to facilitate alignment of the ends of the Y-axis 210 with a reference surface.

[0032] In some embodiments, one end of the Z-axis 310 has a detection head 313, the end of which is tapered, so that the operator can use the detection head 313 to compare with the position to be detected, thereby obtaining more accurate three-dimensional coordinates of the position to be detected.

[0033] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below: First, one end of the X-axis 110 is pressed against a reference surface. Then, the Y-connector 220 is slid to move the Y-axis 210 relative to the X-axis 110. Next, the Y-axis 210 is moved relative to the Y-connector 220, so that the other end of the Y-axis 210 presses against another reference surface. Then, the Z-connector 320 is slid to move the Z-axis 310 relative to the X-axis, and the Z-axis 310 is moved relative to the Z-connector 320, so that one end of the Z-axis 310 is aligned with the position to be measured. At this point, by referring to the X-scale (not shown in the figure), Y-scale (not shown in the figure), and Z-scale (not shown in the figure), the three-dimensional coordinates of the position to be measured can be obtained. Using the above three-dimensional measuring instrument, the three-dimensional coordinates of various positions to be measured on the workpiece can be detected, thereby directly obtaining the three-dimensional dimensions of the workpiece.
