Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of measurement, in particular to a measurement carrier and a measurement device. BACKGROUND

[0002] In the field of electronic product manufacturing, such as the production process of computers, displays and mobile phones, the size processing precision (such as depth, height, step difference, etc.) of spare parts is related to the accuracy of assembly. These spare parts often contain multiple different measurement points, and the accuracy of each point size measurement is closely related to the quality of the final product.

[0003] The traditional measurement method mainly relies on manual operation of a scale to complete. The specific operation process is as follows: first, place the measured object properly and make it in place, then fix and press it tightly to ensure stability during measurement; then, calibrate and zero the scale to prepare for accurate measurement; on this basis, the operator needs to carefully lift the measuring head with one hand and move the scale with the other hand to accurately position each relevant measurement point and then implement measurement operation. However, this traditional measurement method has obvious drawbacks. Since it involves many checking steps and complex operation links, when faced with the need to measure multiple spare parts and the multiple measurement points they contain, the entire operation process is long and tedious. This not only significantly increases the number of measurement steps and the complexity of operation, but also ultimately leads to extremely low measurement efficiency, making it difficult to meet the needs of modern high-efficiency production.

[0012] In some embodiments, the linkage mechanism further comprises an elastic member having two ends respectively connected to one side of the support block away from the gauge and one end of the lever away from the gauge.

[0026] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0027] Please see Figure 1 and Figure 2This application provides a measuring carrier 100 for mounting a gauge 200 on an object 300 to be measured. The measuring carrier 100 includes a supporting mechanism 10 and a linkage mechanism 20. The supporting mechanism 10 is used to move the gauge 200 to the measurement point on the object 300. The linkage mechanism 20 is used to control the gauge 200 to approach the measurement point on the object 300 to measure the size of the measurement point. The size of the measurement point may be, but is not limited to, depth, height, and step difference.

[0028] To illustrate the connection between the measuring device 100 and the gauge 200, the structure of the gauge 200 is first described. The gauge 200 includes a gauge body 201, a gauge rod 202 fixedly connected to the gauge body 201, a measuring rod 203 slidably connected to the gauge rod 202, and a probe 204 disposed at the end of the measuring rod 203. Before measurement, the probe 204 and the measuring rod 203 slide toward the gauge rod 202. During measurement, the probe 204 corresponds to the point to be measured. Then, the probe 204 is released, and the probe 204 and the measuring rod 203 slide toward the object to be measured 300. When the probe 204 reaches the point to be measured, the gauge body 201 displays the measurement result.

[0029] Specifically, the linkage mechanism 20 includes a support block 21 and a lever 22. The support block 21 is connected to the bearing mechanism 10 and to the gauge 200 for supporting the gauge 200. The lever 22 is rotatably connected to the support block 21, and one end of the lever 22 is movably connected to the probe 204 of the gauge 200, so that by rotating the lever 22, the probe 204 of the gauge 200 can be moved away from the test point on the object to be measured 300. When the lever 22 is released, the probe 204 of the gauge 200 comes into contact with the test point and measures the test point.

[0030] In this embodiment, the support block 21 is connected to the gauge 200 to support the gauge 200. Specifically, the support block 21 can be connected to the gauge rod 202 of the gauge 200. The middle part of the lever 22 can be a plate-like structure, with a pressing part 221 at one end for easy pressing operation by the operator. The other end of the lever 22 can be movably connected to the measuring rod 203 of the gauge 200 so that when the operator presses the pressing part 221, it pushes the measuring rod 203 against the gauge body 201 and slides it. A pad or other structure can be fixedly connected to the measuring rod 203. The lever 22 can push against the pad to make the measuring rod 203 slide towards the gauge body 201, thereby driving the probe 204 to slide towards the gauge body 201.

[0031] During use, the aforementioned measuring carrier 100 rotates by pressing the pressing part 221 of the lever 22, causing the end of the lever 22 that abuts against the measuring rod 203 to tilt upwards, thereby pushing the measuring rod 203 and the probe 204 toward the meter body 201. Then, the bearing mechanism 10 moves the meter 200 above the measurement point of the object to be measured 300. When the pressing part 221 of the lever 22 is released, the probe 204 of the meter 200 moves toward the measurement point under the drive of the internal structure of the meter 200. When the probe 204 contacts the measurement point, the meter 200 displays the measurement data, thus enabling rapid measurement of the height or thickness of the object to be measured 300.

[0032] In the measuring carrier 100 provided in this embodiment, the measuring instrument 200 is moved to the measurement point of the object 300 by the supporting mechanism 10. By pressing the lever 22, the lever 22 is rotated, which in turn moves the probe 204 toward the measuring instrument 200 body through the end of the lever 22 connected to it. Releasing the lever 22 allows the probe 204 to move toward the measurement point, enabling rapid measurement of the dimensions of the object 300. When using the device, the operator only needs to hold the supporting mechanism 10 with one hand and press and release the lever 22 in sequence to perform the measurement, simplifying the measurement operation steps and effectively improving measurement efficiency.

[0033] In some embodiments, see Figure 1 and Figure 2 The bearing mechanism 10 includes a base 11 and a slide rod 12. The slide rod 12 is located on the base 11, and the support block 21 is slidably connected to the slide rod 12 and can be positioned at a preset position on the slide rod 12. This is used to adjust the distance between the support block 21 and the object to be measured 300, thereby adjusting the distance between the meter body 201 supported on the support block 21 and the object to be measured 300 to adapt to different measuring ranges.

[0034] In some embodiments, see Figure 1 and Figure 2 The support block 21 is provided with a sliding hole 211, through which the slide rod 12 passes. The wall of the sliding hole 211 is provided with an adjustment hole 212 that passes through the support block 21. In order to improve the stability of the support block 21 on the slide rod 12, in this embodiment, the cross-section of the slide rod 12 is approximately rectangular, and the cross-section of the sliding hole 211 is a rectangle that matches the slide rod 12. In this way, the support block 21 can be rotated when the height of the support block 21 is adjusted.

[0035] The linkage mechanism 20 also includes a tightening member 23, which is installed in the adjustment hole 212. The tightening member 23 is used to hold the slide rod 12 in the sliding hole 211 so that the support block 21 is positioned in the preset position of the slide rod 12. The tightening member 23 can be a stop bolt or the like, and has a knob at one end. The tightening member 23 is threadedly connected to the support block 21 and inserted into the sliding hole 211. By rotating the tightening member 23, it can move toward or away from the slide rod 12. When the tightening member 23 moves toward the slide rod 12, it can hold the slide rod 12, thereby fixing the support block 21. When the tightening member 23 moves away from the slide rod 12, it releases the slide rod 12, at which point the position of the support block 21 on the slide rod 12 can be adjusted.

[0036] In some embodiments, see Figure 2 and Figure 3 The end of the tightening member 23 is provided with a conical surface 231 arranged around it. The slide rod 12 is provided with a sliding groove 121 that passes through the opposite side walls of the slide rod 12. The sliding groove 121 has two inclined walls 122 on the side facing the tightening member 23. The inclination angle of the two inclined walls 122 of the sliding groove 121 is equal to the inclination angle of the conical surface 231. The sliding groove 121 passes through the two side walls of the slide rod 12 facing and away from the gauge 200. The two inclined walls 122 are respectively provided on the two side walls of the sliding groove 121. When the tightening member 23 is locked, the conical surface 231 abuts against the two groove walls, effectively reducing the screwing force required to lock the tightening member 23 and improving the reliability of the tightening member 23.

[0037] In some embodiments, see Figure 2 and Figure 3 The base 11 has a limiting groove 111, and one end of the slide rod 12 is disposed in the limiting groove 111. The bearing mechanism 10 also includes an inner support member 13, which is inserted into one end of the slide rod 12 located in the limiting groove 111 and connected to the base 11. The inner support member 13 abuts against the inner walls of both sides of the sliding through groove 121. The structure of the limiting groove 111 is adapted to the structure of the slide rod 12. The inner support member 13 can be a countersunk bolt, etc. When the slide rod 12 is connected to the base 11, one end of the slide rod 12 is disposed in the limiting groove 111 and is fixedly connected to the base 11 through the inner support member 13. The groove wall of the limiting groove 111 can abut against the outer wall of the slide rod 12, and the inner support 13 can support the two inner walls of the limiting groove 111. This can prevent the two side walls of the sliding through groove 121 of the slide rod 12 from opening or shrinking, which would affect the movement of the support block 21 on the slide rod 12 when the side walls open, or cause the support block 21 to shake when the side walls shrink.

[0038] In some embodiments, see Figure 2 , Figure 3 and Figure 4The support block 21 has a receiving groove 213, which is connected to the sliding through groove 121. The lever 22 is movably inserted through the receiving groove 213 and the sliding through groove 121. In this embodiment, the receiving groove 213 penetrates the side wall and lower side wall of the support block 21 away from the gauge 200. The pivot of the lever 22 is inserted into the receiving groove 213, and the lever 22 can rotate in the sliding through groove 121. By setting the receiving groove 213 and connecting it with the sliding through groove 121, the middle part of the lever 22 can be hidden inside the support block 21, avoiding other structures from affecting the movement of the lever 22. At the same time, it can improve the symmetry of the overall structure of the measuring device 100 and improve the stability of the measuring device 100.

[0039] Please see Figure 1 , Figure 2 and Figure 3 The support block 21 has an extension 214. At the end of the extension 214 away from the support block 21, two opposing pressure arms 215 are provided. The pressure arms 215 are used to clamp and fix the gauge 200. The linkage mechanism 20 also includes a fastener 27, which is located between the two pressure arms 215 and used to adjust the distance between them. Specifically, the pressure arms 215 clamp the gauge rod 202 and align the end of the measuring rod 203 towards the measurement point on the object 300, thereby aligning the probe 204 mounted on the end of the measuring rod 203 towards the measurement point on the object 300, improving measurement stability. The fastener 27 can be a bolt or similar structure. The fastener 27 is threadedly connected to both pressure arms 215. Adjusting the distance between the two pressure arms 215 using the fastener 27 adapts it to gauges 200 of different sizes, improving the versatility of the measuring carrier 100.

[0040] In some embodiments, see Figure 1 , Figure 3 and Figure 4 The linkage mechanism 20 also includes an elastic element 24. The two ends of the elastic element 24 are connected to the side of the support block 21 away from the gauge 200 and the end of the lever 22 away from the gauge 200, respectively. The elastic element 24 is used to pull the lever 22 to rotate so that the lever 22 returns to its original position. The elastic element 24 can be a spring or other elastic structural component. By setting the elastic element 24, the lever 22 can be pulled to rotate, so that the end of the lever 22 with the pressing part 221 can be released and quickly return to its original position. The end of the lever 22 connected to the probe 204 can quickly move away from the gauge body 201, which facilitates improved measurement speed. At the same time, it can also prevent the end of the lever 22 connected to the probe 204 from stopping the probe 204 from moving towards the measurement point, thus improving measurement accuracy.

[0041] In some embodiments, see Figure 2 , Figure 3 and Figure 4The linkage mechanism 20 also includes an upper limit member 25 and a lower limit member 26. Both the upper limit member 25 and the lower limit member 26 are connected to the end of the support block 21 furthest from the gauge 200. The upper limit member 25 is positioned above the lever 22, and the lower limit member 26 is positioned below the lever 22. The upper limit member 25 and the lower limit member 26 are used to limit the rotational position of the lever 22. The upper limit member 25 can be a pin-shaped structure, which can be inserted into the receiving groove 213 of the support block 21. This stops the lever 22 when the end of the lever 22 with the pressing part 221 moves upward, thus limiting the upper limit of the lever 22's rotation. The lower limit member 26 can be a bolt, etc., and can be threadedly connected to the support block 21. Its nut can correspond to the receiving groove 213 to stop the end of the lever 22 with the pressing part 221 from moving downward, thereby limiting the lower limit of the lever 22's rotation.

[0042] In some embodiments, see Figure 2 and Figure 3 The lever 22 is connected to one end of the gauge 200 and has a U-shaped groove 222 for holding the measuring rod 203 of the gauge 200. In this embodiment, the U-shaped groove 222 is used to hold the end of the measuring rod 203 away from the pressure arm 215.

[0043] In some embodiments, see Figure 3 and Figure 4 A connecting hole 112 is provided on the side of the base 11 away from the slide rod 12. The connecting hole 112 can be a threaded hole or the like. The bearing mechanism 10 is also provided with a counterweight 113. The counterweight 113 is inserted into the connecting hole 112 by bolts or other structures, and is thus fixedly connected to the base 11. The counterweight 113 is used to improve the stability of the base 11. It can be understood that in actual measurement, the object to be measured 300 may be located at a higher position, while the base 11 is placed at a lower position than the object to be measured 300. Therefore, a longer slide rod 12 can be used to adjust the height of the support block 21 and the gauge 200. However, this would cause instability of the center of gravity. By connecting the counterweight 113 to the base 11, the stability of the measuring device 100 can be improved.

[0044] The working process of the measuring vehicle 100 provided in this embodiment is roughly as follows:

[0045] First, the gauge 200 is installed on the measuring carrier 100. The gauge rod 202 of the gauge 200 is clamped by two pressure arms 215 and locked with fasteners 27. At this time, the U-shaped groove 222 of the lever 22 is movably engaged with the measuring rod 203 of the gauge 200. Then, the height of the support block 21 is adjusted according to the measurement requirements. During adjustment, the tightening member 23 is loosened first, and the support block 21 is slid along the slide rod 12. The support block 21 can drive the gauge 200 to move synchronously. After adjusting to the appropriate position, the tightening member 23 is tightened to fix the support block 21.

[0046] Before testing, the operator can hold the base 11 and press the pressing part 221 of the lever 22 with their fingers so that one end of the lever 22 with the U-shaped groove 222 pushes the measuring rod 203 and the probe 204 of the gauge 200 toward the gauge body 201.

[0047] During testing, the operator moves the base 11 close to the object to be tested 300. Ideally, the object to be tested 300 and the measuring carrier 100 can be placed on the same platform, with the probe 204 aligned with the measurement point on the object to be tested 300. The operator can use their other hand to press down on the object to be tested 300 to improve accuracy. Then, the pressing part 221 is released, and the elastic element 24 pulls the lever 22 to rotate and reset. Driven by its own structure, the gauge 200 brings the probe 204 into contact with the measurement point, allowing measurement to be performed.

[0048] After the measurement is completed, or when measuring the next point to be measured, the operator presses the pressing part 221 of the lever 22 and then moves the base 11.

[0049] This application embodiment also provides a measuring device 1000 for measuring an object 300. The measuring device 1000 includes the aforementioned measuring carrier 100 and a gauge 200, which is connected to the support block 21 of the measuring carrier 100.

[0050] In some embodiments, the gauge 200 includes a gauge body 201, a gauge rod 202, a measuring rod 203, and a probe 204. The gauge body 201 is used to display the measurement result, the gauge rod 202 is fixedly connected to the gauge body 201, the measuring rod 203 is slidably connected to the gauge rod 202, and the probe 204 is disposed at the end of the measuring rod 203 away from the gauge rod 202, and the probe 204 is used to contact the measurement point of the object to be measured 300.
