Three dimensional measuring device for digital caliper

Abstract

To provide an easy-to-use three dimensional measuring instrument using digital calipers.SOLUTION: Digital calipers X1, Y2, and Z3 are assembled by a connecting member to form a measuring device having a three dimensionally movable structure. The measuring element 20 is attached to an outside jaw of a digital caliper X1 by a facing screw 19 so as to be replaceable with respect to a measuring object. It can be attached to and detached from the measuring plate 33 by a clip 34 or the like, and has a structure easy to carry. The above is slid to bring the probe 20 into contact with a reference position of the object to be measured, and the ZERO buttons of the liquid crystal display units of the digital calipers X1, Y2, and Z3 are pressed. Next, when the probe 20 is brought into contact with a point to be measured in the same manner, the numerical values displayed on the liquid crystal display units of the digital calipers X1, Y2, and Z3 become measured values.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a three-dimensional measuring device using a digital caliper. [Background technology]

[0002] There are excellent 3D measuring devices such as laser, X-ray, and mechanical types, but they are highly accurate and expensive. Although the level of precision mentioned above is not required, there was a need for an inexpensive, easy-to-use 3D measuring device. Summary of the Invention [Problem to be solved by the invention]

[0003] Create an easy-to-use 3D measuring device using digital calipers. [Means for solving the problem]

[0004] Digital calipers X1, Y2, and Z3 are assembled with connecting members, allowing them to move in three dimensions (X: left and right, Y: up and down, Z: back and forth). Screw square pipes A5, B6, C7, D8, and E9 onto square pipe stand 4 to create a vertical stand. The digital caliper X1 (processed product) is screwed to the connecting plate 10 with the mold materials Xa11 and Xb12 facing downwards. The digital caliper Y2 (processed product) is screwed to the connecting plate 10 at a right angle to the digital caliper X1 with the plate Ya15 facing downwards. Then, the main scale part of the assembled digital caliper Y2 is screwed to the square pipes D8 and E9 so that it can move in the Y direction. Next, for the digital caliper Z3 (processed product), place plate Za22 on the top surface of square pipe A5 and screw it in place, creating a three-dimensional structure for the three digital calipers. Also, attach roller 26 to the underside of square pipe C7. By screwing the main scale part of the digital caliper Z3 mentioned above to the combined assembly consisting of the square pipes Za29 and Zb30 and the mold material Za31 screwed to it, a 3D measuring device body that can also move in the Z direction is created. The probe 20 is designed to be attached to the outer jaw of the digital caliper X1 with a decorative screw 19.

[0005] Slide the connecting plate 10 with the scale part of the digital caliper X1, the LCD part of the digital caliper Y2, and the square pipe stand 4 with the LCD part of the digital caliper Z3 together, place the contact point 20 on the point that will be the reference point for the object to be measured, and press the ZERO button on the LCD parts of the digital calipers X1, Y2, and Z3. Next, place the contact point 20 on the point you want to measure in the same way, and the values ​​displayed on the LCD parts of the digital calipers X1, Y2, and Z3 will be the measured values. [Effects of the Invention]

[0006] Using a digital caliper 3D measuring device makes it easy to perform 3D measurements. [Brief explanation of the drawings]

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Place the digital caliper X1 on the connecting plate 10 with the moldings Xa11, Xb12, and spacers Xa13, Xb14, and screw the LCD part in place. Furthermore, place the plate Xa15, spacers Ya16, Yb17 on the connecting plate 10 with the digital caliper Y2 on top of that, and screw the LCD part in place at a right angle to the digital caliper X1. Next, the anti-rattle spring 18 of the digital caliper X1 is screwed to the connecting plate 10. The probe 20 is attached to the outer jaw of the digital caliper X1 with a decorative screw 19, but this is done after the entire assembly is completed. Assemble square pipes A5, B6, C7, D8, and E9 into square pipe stand 4 and screw them together to form a vertical stand. Then, place the main scale part and plate Yb21 of the assembled digital caliper Y2 onto square pipes D8 and E9 screwed to square pipe stand 4 and screw them together. Next, place plate Za22, spacers Za23, and Zb24 on the top of square pipe A5 next to the square pipe stand 4, then place digital caliper Z3 on top of them, and screw the LCD part in place so that it is perpendicular to the square pipe stand 4. A roller 26 is placed inside the mold Ca25, a pipe 27 is passed through it, and then the mold Cb28 is placed on top of the mold Ca25 and screwed together to create a combined part, which is then screwed into the inside of the square pipe C7 located next to the bottom of the square pipe stand 4. The mold material Za31 is screwed to the square pipes Za29 and Zb30 to create a combined part, and the main scale part of the assembled digital caliper Z3, plate Yb21, and mold material guide 32 are set into this and screwed together to form the main body of the 3D measuring device. The main body of the three-dimensional measuring instrument is placed on a measuring plate with legs 33 and secured with clips 34, etc. This structure makes it easy to attach, detach, and carry.

[0009] An example of the use of the present invention will be given. The probe 20 is attached to the outer jaw of the digital caliper X1 with the decorative screw 19. Slide the connecting plate 10 with the scale part of the digital caliper X1, the LCD part of the digital caliper Y2, and the square pipe stand 4 with the LCD part of the digital caliper Z3, place the contact point 20 on the position of the measuring plate 33 that will be the reference for the object to be measured, and press the ZERO button on the LCD parts of the digital calipers X1, Y2, and Z3. Another method is to fix graph paper on the measuring plate 33 and use any point where the lines on the graph paper intersect as the reference. The object to be measured is fixed to the measuring plate 33 . Next, as described above, place the probe 20 on the point on the object you want to measure, and the values ​​displayed on the LCD display of the digital caliper X1, Y2, and Z3 will be the measured values. The contact point 20 can be selected and replaced depending on the object being measured, and is attached to the outer jaw of the digital caliper X1 with a decorative screw 19.
