[0041] Figure 4 The clamping schematic diagram of the measuring tool provided by the embodiment of the present application when measuring the part to be measured is provided; Figure 5 The Figure 4 The enlarged view at A in the middle.
[0042] As Figures 1-5 shown, the measuring tool 100 can include a base and a positioning mechanism. The base includes a base plate and a support column; the positioning mechanism includes a first positioning block 130 and a positioning pin 150. The support column includes a first support column 121 and a second support column 122, wherein the first support column 121 supports the first positioning block 130, and the second support column 122 supports the second positioning block 140. The first positioning block 130 has a first positioning hole 131 thereon, and the part to be measured 200 has a second positioning hole thereon, and the positioning pin 150 can pass through the first positioning hole 131 and the second positioning hole in turn. Wherein, the positioning pin 150 can be a stepped pin.
[0043] It is worth noting that the measuring tool 100 realizes accurate positioning of the measuring tool 100 and the part to be measured 200 by using the positioning pin 150. In batch measurement, the position consistency of the part to be measured can be effectively guaranteed, avoiding repeated manual adjustment of the positioning reference due to inconsistent part placement position, reducing the manual intervention step, thereby improving the measurement efficiency and meeting the demand of mass production.
[0044] Please refer again to Figures 1 to 3 , the base plate 110 also has a first profiling block 111, a second profiling block 112 and a third profiling block 113, and the lower part surface of the part to be measured 200 is in conformity with the surface on the first profiling block 111, the second profiling block 112 and the third profiling block 113. The measuring tool further includes a second positioning block 140, and the side surface of the part to be measured 200 is in conformity with the surface on the second positioning block 140.
[0045] It is worth mentioning that the measuring tool 100 can further improve the positioning accuracy by setting the profile that matches the part to be measured 200 on the first profiling block 111, the second profiling block 112, the third profiling block 113 and the second positioning block 140.
[0046] Please refer to Figures 1 to 3 , the base 110 and the positioning mechanism can be made of aluminum alloy.
[0047] It should be understood that aluminum alloy has the characteristics of light weight and high strength. The use of aluminum alloy to manufacture the measuring tool 100 can facilitate the movement and operation of the measurement technician in different scenarios, bringing convenience and applicability to the actual measurement operation.
[0048] Please refer to Figure 4 and Figure 5 , the measuring tool 100 further comprises a locking mechanism comprising a screw 161 and a pressing plate 162. The locking mechanism is arranged at the matching position between the part to be measured 200 and the measuring tool 100, so that the profile on the part to be measured 200 and the first profiling block 111, the second profiling block 112, the third profiling block 113 and the second positioning block 140 are matched. Each matching position is lightly pushed or lightly pressed by the screw 161 in cooperation with the pressing plate 162, and after each profile on the measuring tool 100 is matched, it can be clamped stably.
[0049] The screw 161 can be made of nylon material, such as flexible nylon material. The pressing plate 162 can be made of plastic material.
[0050] It is worth mentioning that the measuring tool 100 sets the locking mechanism, uses flexible nylon screw and plastic pressing plate, which can avoid bruising the part to be measured 200 while ensuring the clamping rigidity of the measurement, preventing the small displacement or uneven force between the tool and the part from interfering with the measurement result, ensuring that the measurement result can accurately reflect the true quality state of the part, and ensuring the reliability and accuracy of the measurement result.
[0051] Please refer to Figure 3 , the measuring tool 100 is a self-symmetrical structure. The measuring tool 100 can be used to clamp the mirror image part of the part to be measured, the first positioning block 130 has a third positioning hole 133, the mirror image part has a fourth positioning hole, and the positioning pin 150 can pass through the third positioning hole 133 and the fourth positioning hole in sequence. If there are two parts that are mirror images of each other, the left part uses the measuring tool 100 to clamp and measure on one side of the first positioning hole 131, and the right part uses the measuring tool 100 to clamp and measure on one side of the third positioning hole 133.
[0052] It is worth mentioning that the measuring tool 100 is a self-symmetrical structure, and is compatible with parts having a mirror image relationship. Through the setting of the symmetrical positioning hole, one tool can meet the measurement requirements of left and right parts or other mirror image parts, and it is not necessary to make a measuring tool for each part, thereby reducing the equipment cost. Meanwhile, when the part is replaced for measurement, it is only necessary to select the corresponding side clamping according to the symmetrical structure, and the operation is simple, efficient, convenient and high.
[0053] In addition, the measuring tool 100 is a vertical structure, so that the part is in a vertical state after clamping, and the three-coordinate measuring machine can measure the front and back surfaces of the part at one time, thereby reducing the operation of multiple clamping and repositioning the reference, saving the measurement time, and also reducing the measurement error caused by multiple operations, and improving the overall efficiency and precision of the production measurement process.
[0054] The above is only a preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application is included in the protection scope of the present application.
