Description

Technical Field

[0001] This utility model relates to the field of concrete mold verification technology, and in particular to a multifunctional testing device for mold verification. Background Technology

[0002] Mold calibration includes checking internal surface roughness, internal dimensions, included angles, flatness, and gaps. Among these, the included angle of the assembled mold is the least operable aspect with current equipment. The included angle (or perpendicularity) of the mold refers to the angular tolerance (or perpendicularity) between the contact surfaces of the inner wall after the concrete strength test mold is assembled. The qualification of the mold is crucial to whether the final specimen dimensions meet the requirements. If the specimen dimensions do not meet the requirements, it will have a particularly large impact on the strength test value of high-strength concrete. When the pressure surface is not parallel or the flatness does not meet the requirements, the strength test value will be significantly reduced.

[0003] Existing methods for mold verification typically have the following major drawbacks: ① The knife-edge right-angle ruler or right-angle ruler used cannot visually inspect the perpendicularity deviation between the side walls of the mold; ② When using a right-angle ruler in conjunction with a feeler gauge, trial measurements are required, which is time-consuming and labor-intensive; ③ Calipers and depth gauges are not suitable for measuring the lower opening dimensions of the assembled mold, as they can only measure the opening portion; ④ All verification items for the entire mold require a surface roughness measuring instrument, knife-edge right-angle ruler, feeler gauge, special perpendicularity gauge, calipers, depth gauge, Class 1 flat plate, right-angle ruler, etc., making the equipment complex.

[0004] Therefore, it is necessary to propose a multifunctional testing device for trial mold verification to solve or at least alleviate the above-mentioned defects. Utility Model Content

[0029] Please see the appendix Figure 1-2 The present invention provides a multifunctional testing device for mold verification in one embodiment, comprising a fixed ruler 110, an angle scale 120, an angle indicator 130, a movable ruler 140, a flatness measuring device 150, and a movable auxiliary ruler 160, the specific scheme of which is as follows:

[0030] The angle scale 120 is fixedly connected to the first end of the fixed scale 110. The angle scale 120 is arc-shaped and has angle scale values ​​equidistantly arranged along its circumference. The first end of the movable scale 140 is connected to the second end of the fixed scale 110, and the second end of the movable scale 140 is rotatably arranged around its first end. The angle indicator 130 includes a connecting end and an indicating end. The connecting end is connected to the first end of the movable scale 140, and there is a fixed angle between the angle indicator 130 and the movable scale 140. The indicating end is used to point to the angle scale value. The flatness measuring device 150 is connected to the movable scale 140 for testing the distance between the working surface of the test mold and the movable scale 140. The movable auxiliary scale 160 is connected to the second end of the movable scale 140 and is telescopically arranged along the extension direction of the movable scale 140. The movable auxiliary scale 160 has length scale values ​​equidistantly arranged along its extension direction.

[0031] Specifically, the multifunctional testing device for mold calibration in this application includes a fixed ruler 110, an angle scale 120, an angle indicator 130, a movable ruler 140, a flatness measuring device 150, and a movable auxiliary ruler 160. The fixed ruler 110 is used for mounting and connecting other testing components. The angle scale 120 is used to detect the included angle of the inner wall of the mold and is mounted on the first end of the fixed ruler 110. The angle indicator 130 is used to indicate the angle scale value on the angle indicator 130 to display the specific angle when measuring the angle. It needs to be used in conjunction with the movable ruler 140 during measurement. The movable ruler 140 can swing around the second end of the fixed ruler 110, thus connecting the angle indicator 130. The fixed ruler 110 is connected to the movable ruler 140 to swing with it. It is important to note that the angle indicator 130 and the movable ruler 140 have a fixed angle. In use, the fixed ruler 110 is pressed against one inner wall of the mold, and then the movable ruler 140 is manipulated to press against the other inner wall of the mold to match the adjacent inner wall where the mold's angle is located. The angle indicator 130 then rotates with the movable ruler 140. The angle value indicated by the angle indicator 130 plus the initially fixed angle value is the inner wall angle of the mold, thus measuring the inner wall angle of the mold. For example, in this application, the fixed angle between the angle indicator 130 and the movable ruler 140 is 4... 5°. When testing whether the perpendicularity meets the requirements, if the angle indicator 130 points exactly to the 45° scale value, it indicates that the perpendicularity meets the requirements (the angle between the side wall where the movable ruler 140 is located and the side wall where the fixed ruler 110 is located is 90°). If it points to 44.9° (the actual surface angle is 89.9°) or 45.1° (indicating the actual angle is 90.1°), it indicates that there is a deviation in perpendicularity. The same principle applies when measuring other angles of the test mold. Preferably, the fixed angle can also be other angles, as long as a fixed value is maintained. Those skilled in the art can choose according to their needs. The flatness measuring device 150 is used to calibrate the flatness of the working surface of the test mold. It is installed on the movable ruler 140. When the movable ruler 140... When the ruler 140 is attached to the opposite sidewall of the sidewall to be measured, the flatness measuring device 150 faces the sidewall to be measured, thereby measuring the maximum distance between the working surface of the test mold and the movable ruler 140 with the movable ruler 140 as a reference to measure the flatness. In a preferred embodiment of this application, the flatness measuring device 150 can be a laser rangefinder, which occupies little space, is easy to install, and is relatively accurate through laser ranging. The movable auxiliary ruler 160 is used to fix the basic dimensional deviation inspection of each part of the lower opening of the test mold. It is telescopically connected to the second end of the movable ruler 140. During measurement, the movable auxiliary ruler 160 is pulled out to measure the lower opening of the test mold through its own length scale value.

[0032] In a preferred embodiment of this utility model, both the fixed ruler 110 and the movable ruler 140 are straight rulers.

[0033] It should be noted that, considering that the arc-shaped extension end of the angle scale 120 does not form a quarter circle (i.e., the angle scale value does not reach 90°), the fixed scale 110 and the movable scale 140 can be set as rulers, so that the ends are rectangular (the corners of the ends are 90°). When the movable scale 140 is rotated, when the short side of the movable scale 140 is aligned with the long side of the fixed scale 110, that is, the included angle is 90°. If the perpendicularity is not accurate, the alignment may not be achieved. Therefore, this can be used to test the perpendicularity of adjacent inner walls of the test mold, and can also be used as an auxiliary reference in addition to the angle indicator 130.

[0034] In a preferred embodiment of the present invention, the first end of the movable ruler 140 is connected to the second end of the fixed ruler 110 by a hinge.

[0035] It should be noted that a pin can be used to hinge the first end of the movable ruler 140 to the second end of the fixed ruler 110. It is worth mentioning that during installation, the tightness of the pin can be adjusted appropriately to ensure that it is tight enough to prevent loosening during measurement, thereby ensuring measurement accuracy. At the same time, it should not be too tight, so that it is difficult to move the movable ruler 140 and affect operation. The specific tightness can be adjusted by those skilled in the art according to actual needs.

[0036] In a preferred embodiment of this utility model, the center point of the angle scale 120 is the hinge point between the movable scale 140 and the fixed scale 110.

[0037] It is worth noting that since the movable ruler 140 swings in a circle around the second end of the fixed ruler 110, the arc-shaped angle scale 120 also uses the hinge point around which the movable ruler 140 swings as a reference. This makes the arc of the angle scale 120 match the swing trajectory of the movable ruler 140. As a result, after the movable ruler 140 is in contact with the side wall of the test mold, the angle indicator 130 will directly point to the corresponding scale (angle scale value) of the angle scale 120, improving the accuracy of the angle reading and eliminating the reference offset error of the angle measurement.

[0038] In a preferred embodiment of this utility model, the surface roughness Ra of the upper surface of the fixed ruler 110 is 1.6 μm.

[0039] It is worth noting that different Ra values ​​represent different surface roughness. Due to the measurement standard of the test mold, the roughness Ra value of the upper surface of the fixed ruler 110 needs to be maintained at 1.6 μm. It can be used with a 10x magnifying glass to compare the test mold, thereby checking whether the surface roughness of the test mold meets the standard.

[0040] Furthermore, the indicating end of the angle indicator 130 has a sharp angle.

[0041] It should be noted that the sharp corner can precisely align with the single 120° scale line on the angle scale, eliminating visual errors during the reading process and making the reading more intuitive.

[0042] Furthermore, a groove is formed in the recess of the second end of the movable ruler 140, and the movable auxiliary ruler 160 is slidably connected in the groove.

[0043] It should be understood that the slide groove facilitates the sliding of the movable auxiliary ruler 160. When the movable auxiliary ruler 160 is not needed, the movable ruler 140 can be retracted into the slide groove. When the movable auxiliary ruler 160 is needed to check the basic dimensional deviation of each part of the mold bottom, it can be pulled out along the inner wall of the slide groove. It is understood that the tightness of the movable auxiliary ruler 160 also needs to be adjusted appropriately to ensure that it is tight during measurement and easy to push and pull.

[0044] Furthermore, the graduation value of the length scale of the movable auxiliary ruler 160 is no greater than 0.02 mm.

[0045] It should be noted that the graduation value of the length scale of the movable scale 160 can be selected according to the measurement needs. For details, please refer to the trial mold specification requirements. In a preferred embodiment of this application, the graduation value of the length scale of the movable scale 160 is not greater than 0.02mm. Those skilled in the art can set it according to the actual situation.

[0046] Furthermore, the minimum division value of the angle scale 120 is 0.2°.

[0047] Understandably, a minimum division of 0.2° is usually sufficient to meet the observation requirements in trial molding tests. Setting the division value too small would increase the reading requirements and make the process cumbersome. It is not necessary to have such a precise degree. Therefore, a minimum division of 0.2° is more practical and intuitive in this application. It should be noted that the figure shows a division value of 1°. The minimum division value is not shown in the image due to the need for clarity.

[0048] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
