Description

Technical Field

[0001] The utility model relates to the technical field of size measuring devices, in particular to a measuring device. Background Art

[0002] As a dimension measuring device, height gauge is widely used in the field of height dimension measurement due to its low equipment cost and high measurement efficiency compared with three-dimensional coordinate measuring machine. The height gauges currently used in the market are all traditional vertical height gauges. This height gauge is mainly composed of a marble platform, a longitudinal arm, a crossbeam, a digital dial indicator and a height gauge needle. This height gauge is large in size and heavy in weight, which is not conducive to handling and turnover.

[0003] In the related art, when measuring the relative distance between the glass screen assembly surface (referred to as the screen assembly surface) and the appearance surface of the mobile phone middle frame of the curved screen mobile phone, due to the presence of a waterproof surface higher than the screen assembly surface and a 3D arc structure dispensing groove inside the mobile phone middle frame of the curved screen mobile phone, and the narrow width of the screen assembly surface, the traditional vertical height gauge cannot accurately measure the screen assembly surface of the mobile phone middle frame, and thus cannot accurately measure the relative distance between the screen assembly surface and the appearance surface of the mobile phone middle frame. In addition, the traditional vertical height gauge and three-dimensional equal-dimensional measuring body are large in size, inconvenient to move, and have high production and maintenance costs.

[0036] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0037] Reference below Figure 1-Figure 13 A measuring device according to an embodiment of the present invention is described.

[0038] like Figure 1-Figure 13 As shown, the measuring device includes: a mounting frame 2, a measuring table 4 and a rotating component 3.

[0039] The measuring meter 4 is arranged on the mounting frame 2 , and a measuring head 5 is connected to the bottom end of the measuring meter 4 .

[0040] like Figure 1 As shown, the measuring meter 4 is arranged at the top of the mounting frame 2, wherein a horizontal extension structure is provided at the top of the mounting frame 2, so that the measuring meter 4 is arranged on the horizontal extension structure, and the measuring head 5 connected to the bottom end of the measuring meter 4 is located below the horizontal extension structure, so that the measuring head 5 can be aligned with the product to be measured for measurement.

[0041] Exemplarily, the measuring gauge 4 may be a digital dial gauge or a digital micrometer.

[0042] The rotating assembly 3 is rotatably disposed on the mounting frame 2 . The rotating assembly 3 includes an eccentric wheel 31 . The eccentric wheel 31 is configured to abut against the measuring head 5 during rotation to drive the measuring head 5 to move in a vertical direction.

[0043] like Figure 1 As shown, the rotating assembly 3 is arranged at the middle position of the mounting frame 2, so that the eccentric wheel 31 can abut against the measuring head 5. Moreover, the eccentric wheel 31 always abuts against the measuring head 5 during the rotation, so that the measuring head 5 can be driven to move in the vertical direction to measure the height dimension of the product to be measured.

[0044] For example, rotate the eccentric wheel 31 to make the measuring head 5 fit closely with the reference plane of the product to be measured, press the zeroing button of the measuring scale 4 to perform zeroing; then, move the measuring device close to the product to be measured, rotate the eccentric wheel 31 to make the measuring head 5 close to the measuring plane of the product to be measured, and then continue to rotate the eccentric wheel 31 to move the measuring head 5 toward the measuring plane until it contacts the measuring plane. At this time, write down the reading of the measuring scale 4, which is the height dimension of a certain part of the product to be measured.

[0045] See Figure 8-Figure 11 As shown, since there is a waterproof surface 71 higher than the screen assembly surface 73 and a 3D arc structure glue groove 72 inside the mobile phone middle frame 7 of the curved screen mobile phone, and the width of the screen assembly surface 73 is narrow, it is impossible to use a traditional vertical height gauge for measurement.

[0046] Based on this, using the measuring device of the present application, the measuring head 5 can be driven to move in the vertical direction by rotating the eccentric wheel 31, so as to measure the relative distance size between the screen assembly surface 73 and the appearance surface 74 of the mobile phone middle frame 7.

[0047] Specifically, the eccentric wheel 31 is rotated to make the measuring head 5 fit closely with the surface of the support platform 63 of the measuring device, and the zeroing button of the measuring table 4 is pressed to reset to zero. Since the product to be measured, such as the middle frame 7 of a mobile phone, is placed on the measuring device for measurement, the appearance surface 74 of the product to be measured is closely fitted with the surface of the support platform 63 of the measuring device, that is, the reference plane of the product to be measured is the surface of the support platform 63, and the surface of the support platform 63 serves as the reference plane.

[0048] Then, the eccentric wheel 31 is rotated to bring the measuring head 5 close to the screen assembly surface 73, and the measuring head 5 is now higher than the screen assembly surface 73. Then, the measuring device is moved forward to approach the mobile phone middle frame 7, and then the eccentric wheel 31 is further rotated to move the measuring head 5 downward to contact the screen assembly surface 73. At this time, the reading of the measuring table 4 is recorded, and this reading is the relative distance between the screen assembly surface and the appearance surface 74 of the mobile phone middle frame 7.

[0049] Therefore, the following effects can be achieved through the measuring device of the present application:

[0050] First, by rotating the eccentric wheel 31 to control the height of the measuring head 5, the relative distance between the screen assembly surface 73 and the appearance surface 74 of the mobile phone middle frame 7 is measured, which solves the technical problem that the traditional vertical height gauge cannot measure the size of the mobile phone due to structural limitations of the waterproof surface 71, the glue groove 72, and the width of the screen assembly surface 73.

[0051] Second, the zeroing and measuring point of the height of the measuring head 5 are controlled by rotating the eccentric wheel 31, replacing the traditional crossbeam, longitudinal arm, and marble platform, reducing the volume / weight of the height gauge, making the measuring device portable and easy to turn over.

[0052] Furthermore, a relative highest point 311 and a lowest point 312 are provided on the eccentric wheel 31. The eccentric wheel 31 is configured so that when it rotates to the highest point 311 and abuts against the measuring head 5, the measuring end of the measuring head 5 is located above the plane to be measured of the product to be measured. When the eccentric wheel 31 continues to rotate to the lowest point 312 and abuts against the measuring head 5, the measuring end of the measuring head 5 contacts the plane to be measured.

[0053] See Figure 3 As shown, the outer circumferential surface of the eccentric wheel 31 is provided with a relative highest point 311 and a lowest point 312. When measuring the relative distance between the screen assembly surface 73 and the appearance surface 74, the measuring device is first reset to zero, that is, the eccentric wheel 31 is rotated to move the measuring end of the measuring head 5 to fit closely with the surface of the support platform 63 of the measuring device. At this time, zeroing is achieved.

[0054] Then, rotate the eccentric wheel 31 so that its highest point 311 is against the measuring head 5. At this time, move the measuring device forward so that the measuring head 5 is close to the screen assembly surface 73 of the mobile phone middle frame 7, so that the measuring end of the measuring head 5 is located above the screen assembly surface 73 of the mobile phone middle frame 7, and continue to rotate the eccentric wheel 31 so that its lowest point 312 is against the measuring head 5. At this time, the measuring end of the measuring head 5 is in contact with the screen assembly surface 73 of the mobile phone middle frame 7. At this time, write down the reading of the measuring table 4, which is the relative distance size between the screen assembly surface 73 and the appearance surface 74.

[0055] The outer circumferential surface of the eccentric wheel 31 is provided with opposite planes to form a highest point 311 and a lowest point 312 respectively.

[0056] Furthermore, a glue dispensing groove 72 is provided on the product to be tested, the surface to be tested is located below the glue dispensing groove 72, and the waterproof surface 71 is located above the glue dispensing groove 72. The eccentric wheel 31 is configured so that when it rotates to the highest point and abuts against the measuring head 5, the measuring end of the measuring head 5 can be suspended in the glue dispensing groove 72.

[0057] See Fig.10 and Fig.11 As shown, the product to be tested is a mobile phone middle frame 7, and the plane to be tested is a screen assembly surface 73. There are a waterproof surface 71 and a 3D arc structure glue dispensing groove 72 on the mobile phone middle frame 7, which are higher than the screen assembly surface 73. Among them, the screen assembly surface 73 is located below the glue dispensing groove 72, and the waterproof surface 71 is located above the glue dispensing groove 72.

[0058] Combined with Figure 8 and Fig. 9 As shown, when the eccentric wheel 31 rotates to the highest point and contacts the measuring head 5, the measuring device is moved forward to be close to the mobile phone middle frame 7. At this time, the measuring end of the measuring head 5 is suspended in the glue dispensing groove 72. In this way, the measuring end of the measuring head 5 is located exactly between the waterproof surface 71 and the screen assembly surface 73, so that the measuring end of the measuring head 5 will not interfere with the groove wall of the glue dispensing groove 72, the screen assembly surface 73, and the waterproof surface 71, and it is beneficial for the eccentric wheel 31 to continue to rotate to the lowest point so that the measuring end of the measuring head 5 moves downward to contact the screen assembly surface 73.

[0059] Furthermore, the distance from the highest point 311 to the center of the eccentric wheel 31 is A, the distance from the lowest point 312 to the center of the eccentric wheel 31 is B, a needle 54 is provided on the measuring head 5, the thickness of the needle 54 is C, a glue dispensing groove 72 is provided on the inner side of the plane to be measured, and the groove width of the glue dispensing groove 72 is D, and A, B, C and D satisfy the relationship: AB>DC.

[0060] See Figure 10-13As shown, since there are waterproof surfaces 71 higher than the screen assembly surface 73 and glue dispensing grooves 72 with 3D arc structures inside the middle frame 7 of the mobile phone, and the width of the screen assembly surface 73 is relatively narrow, based on this, the height difference between the distance A from the highest point 311 to the center of the eccentric wheel 31 and the distance B from the lowest point 312 to the center of the eccentric wheel 31 is designed to be greater than the difference between the groove width dimension D of the glue dispensing groove 72 and the thickness dimension C of the needle 54 itself, which can ensure that the needle 54 of the measuring head 5 can fit with the screen assembly surface 73 when the eccentric wheel 31 is at the position from the highest point 311 to the lowest point 312.

[0061] Furthermore, the measuring head 5 includes a connected horizontal axis 51 and a vertical axis 53, the vertical axis 53 extends obliquely toward one side of the product to be measured and forms an obtuse angle with the horizontal axis 51, the horizontal axis 51 is connected to the measuring table 4, and a needle 54 is provided at the bottom end of the vertical axis 53, and the needle 54 is adapted to the structure of the product to be measured.

[0062] See Figure 4 As shown, the measuring head 5 includes a horizontal axis 51 and a vertical axis 53, wherein the horizontal axis 51 is provided with a mounting hole 52 for connecting the bottom end of the measuring meter 4. An obtuse angle is formed between the vertical axis 53 and the horizontal axis 51, and the vertical axis 53 extends obliquely toward the outside. Specifically, the vertical axis 53 extends obliquely toward the mobile phone middle frame 7 to be suitable for being close to the screen mounting surface 73 of the mobile phone middle frame 7.

[0063] The angle between the horizontal axis 51 and the vertical axis 53 needs to ensure that the vertical axis 53 does not interfere with the product to be measured when measuring the size. For example, the vertical axis 53 cannot interfere with the waterproof surface 71 of the mobile phone middle frame 7 that is higher than the screen assembly surface 73.

[0064] In addition, a needle 54 is provided at the bottom end of the longitudinal axis 53 , and the structure of the needle 54 is adapted to the structure of the product to be tested.

[0065] For example, see Figure 5 As shown, the needle 54 structure is shaped like the glue dispensing groove 72 structure of the 3D structure, so as not to interfere with the glue dispensing groove 72 structure when measuring the screen assembly surface 73 of the mobile phone middle frame 7.

[0066] Furthermore, a measuring plane 55 is provided at the bottom end of the needle 54, and the measuring plane 55 is suitable for being in close contact with the plane to be measured.

[0067] In this way, when the needle 54 moves to contact the plane to be measured, the measuring plane 55 can fit together with the plane to be measured, such as the screen assembly surface 73 of the mobile phone middle frame 7, thereby ensuring that the needle 54 of the measuring head 5 and the measuring plane of the product to be measured are accurate, thereby improving the measurement accuracy.

[0068] Furthermore, a glue dispensing groove 72 is provided on the inner side of the plane to be measured, the needle 54 is structurally adapted to the glue dispensing groove 72, and the size of the needle 54 is smaller than the size of the glue dispensing groove 72, which can ensure that the measuring head 5 moves smoothly in the glue dispensing groove 72 of the mobile phone middle frame 7 during the measurement process.

[0069] It should be understood that the size of the needle 54 refers to the entire structural size of the needle 54, not just the thickness size.

[0070] Furthermore, the rotating assembly 3 includes: a rotating shaft 32 and a handle 33. The rotating shaft 32 is rotatably arranged in the mounting frame 2. One end of the rotating shaft 32 is connected to the eccentric wheel 31, and the other end is connected to the handle 33, so that the rotating shaft 32 drives the eccentric wheel 31 to rotate under the drive of the handle 33.

[0071] See Figure 2 As shown, the measurement personnel rotates the handle 33 to drive the rotating shaft 32 to rotate relative to the mounting frame 2, thereby rotating the eccentric wheel 31, thereby realizing the movement of the measuring head 5 in the vertical direction.

[0072] The handle 33 may also be replaced with other driving structures, such as a driving motor, as long as it can generate a driving force to drive the rotating shaft 32 and the eccentric wheel 31 to rotate.

[0073] Furthermore, the mounting frame 2 is provided with an assembly hole for the measuring rod of the measuring meter 4 to extend into, and the measuring rod of the measuring meter 4 is inserted into the assembly hole and fixed by screws. In this way, the measuring meter 4 can be fixedly connected to the mounting frame 2.

[0074] Furthermore, the measuring device also includes: a support plate 6, suitable for placing the product to be measured, the support plate 6 includes a support plate body 61, and a support platform 63 is provided at the bottom end of the support plate body 61. The surface of the support platform 63 forms a zeroing plane, which is suitable for fitting with the reference plane of the product to be measured.

[0075] See Figure 6 and Figure 7 As shown, the support plate 6 is arranged on one side of the mounting frame 2 for placing the product to be tested, such as the mobile phone middle frame 7, to ensure that the screen assembly surface 73 of the mobile phone middle frame 7 is stable and does not shake during the measurement process. A support platform 63 is arranged at the bottom end of the support plate body 61 to support the mobile phone middle frame 7 to be attached to the surface of the support plate body 61.

[0076] Furthermore, the surface of the support platform 63 serves as a zeroing plane to closely fit with the exterior surface 74 of the mobile phone middle frame 7 and serves as a reference plane. In addition, the surface of the support platform 63 limits the X-axis position of the mobile phone middle frame 7.

[0077] If this application Figure 7In the illustrated embodiment, a plate-like structure is provided at the bottom of the support platform 63, which provides a larger supporting area for the support plate 6 so that it can sit stably and is not easy to fall down.

[0078] Specifically, the eccentric wheel 31 is rotated to make the measuring head 5 fit closely with the surface of the support platform 63 of the measuring device. At this time, the zeroing button of the measuring table 4 is pressed to return to zero.

[0079] Furthermore, the support plate 6 includes: a limit block 62, which is arranged on one side of the support plate body 61 and is suitable for limiting and cooperating with one side of the product to be tested. Figure 8 and Fig. 9 As shown, a limiting block 62 is provided on the side of the supporting plate body 61 to limit the Y-axis position of the mobile phone middle frame 7 .

[0080] Furthermore, a magnetic suction groove 64 is provided on the support plate body 61, and the magnetic suction groove 64 is used to place a magnetic suction member, and the magnetic suction member is used to magnetically attract with a magnetic suction member placed on the product to be tested. Figure 7 As shown, one or more magnetic suction grooves 64 are provided on the support plate body 61, and magnetic suction parts such as magnets are installed in the magnetic suction grooves 64. Correspondingly, magnetic suction parts such as magnets are placed on the mobile phone middle frame 7 to ensure that the mobile phone middle frame 7 is tightly fitted with the support plate body 61 during the measurement process.

[0081] It should be noted that there is no magnetic attraction structure in the structure of the mobile phone middle frame 7 itself. In order to ensure that the mobile phone middle frame can be stable and motionless during the measurement process, a magnetic attraction structure is placed on the mobile phone middle frame 7 and a magnetic attraction structure is placed on the support plate main body 61, so that the mobile phone middle frame 7 and the support plate main body 61 are closely fitted to ensure measurement accuracy.

[0082] Of course, the above is only one implementation of the present application, and the implementation is simple to operate. The present application can also set other structures on the support plate 6 to further fix the mobile phone middle frame 7.

[0083] Therefore, a limit block 62 is provided on the side of the support plate body 61 to limit the Y-axis position of the mobile phone middle frame 7; a support platform 63 is provided at the bottom of the support plate body 61. During the measurement process, the appearance surface 74 of the mobile phone middle frame 7 is closely attached to the surface of the support platform 63. The surface of the support platform 63 acts as a reference surface to limit the X-axis position of the mobile phone middle frame 7. In addition, during the measurement process, the mobile phone middle frame 7 is closely attached to the support plate 6 by magnetic attraction.

[0084] Furthermore, the measuring device further comprises: a bottom plate 1, a mounting frame 2 is arranged on the bottom plate 1, and one side of the bottom plate 1 is used to abut against the side wall of the support platform 63. Figure 1 and Figure 6 , Figure 7As shown, the mounting frame 2 is arranged on the bottom plate 1, which is convenient for moving the measuring device. And, when the measuring head 5 is closely attached to the surface of the support table 63, the zeroing button is pressed to reset to zero. When the eccentric wheel 31 rotates so that its highest point 311 abuts against the measuring head 5, at this time, the bottom plate 1 can be moved to abut against the side wall of the support plate 6 so that the measuring head 5 is close to the product to be measured, and then the eccentric wheel 31 is rotated, and the measuring head 5 moves downward, so that the measuring head 5 moves to fit the plane to be measured, such as the screen assembly surface 73.

[0085] Specific implementation plan of this measurement tool:

[0086] First, fix the product to be tested: fit the appearance surface 74 of the middle frame 7 of the mobile phone to be tested tightly with the surface of the support platform 63 (i.e., the zeroing plane), fit the middle frame 7 of the mobile phone tightly with the limit block 62 on the side of the support plate body 61, and place one or more magnetic parts such as magnets on the middle frame 7 of the mobile phone, and ensure that the middle frame 7 of the mobile phone fits tightly on the support plate 6 by magnetic attraction between the magnets on the support plate 6 and the magnetic parts such as magnets on the middle frame 7 of the mobile phone.

[0087] Secondly, the measurement reference plane is reset to zero: the handle 33 is turned to drive the eccentric wheel 31 to rotate, the needle 54 is closely attached to the zeroing plane, and the zeroing button is pressed to reset to zero.

[0088] Then, the size of the screen assembly surface 73 is measured: the eccentric wheel 31 is driven to rotate by shaking the handle 33, and the needle 54 is moved close to the screen assembly surface 73 when the eccentric wheel 31 rotates to the highest point 311. Next, the measuring device is moved forward until the bottom plate 1 and the side wall of the support plate 6 (here specifically a side wall of the support platform 63) are closely fitted, and the handle 33 is driven to drive the needle 54 to move downward, and the needle 54 is stopped when the needle 54 rotates to the lowest point 312 to ensure that the needle 54 is in contact with the screen assembly surface 73. The reading of the measuring table 4 is recorded, and this reading is the relative distance size between the screen assembly surface 73 and the appearance surface 74.

[0089] Therefore, the following effects can be achieved through the measuring device of the present application:

[0090] First, by rotating the eccentric wheel 31 to control the height of the measuring head 5, the relative dimensions of the screen assembly surface 73 and the appearance surface 74 of the mobile phone middle frame 7 are measured, which solves the technical problem that the traditional vertical height gauge cannot measure the dimensions of the mobile phone due to structural limitations of the waterproof surface 71, the glue dispensing groove 72, and the width of the screen assembly surface 73.

[0091] Second, the zero return and measurement point of the height of the measuring head 5 are controlled by rotating the eccentric wheel 31, replacing the traditional crossbeam, longitudinal arm, and marble platform, reducing the weight of the height gauge, making it portable and easy to turn around.

[0092] Thirdly, by using the surface of the support platform 63 of the support plate 6 as the zeroing plane, the processing costs of the marble platform, the longitudinal arm and the crossbeam are reduced, and the cost of manufacturing the measuring tool is saved.
