[0001] This application relates to the field of measuring equipment technology, and specifically to a measuring device. Background Technology

[0002] Currently, in the manufacturing process of workpieces, there are often feature structures on the workpiece used for positioning or assembly, such as blind holes, keyways, and protrusions. To determine whether these feature structures have been machined correctly, the common method is to manually measure them using a ruler. However, when the feature structure is small, the ruler has difficulty contacting it, making this method unsuitable for measuring small feature structures. Furthermore, measuring with a ruler has low accuracy, leading to significant measurement errors. Utility Model Content

[0003] In view of the above, it is necessary to propose a measuring device to meet the measurement requirements of small-sized feature structures and reduce measurement errors.

One end of the limiting member is connected to and extends to the side of the limiting member away from the extrusion assembly; a clamping elastic member is sleeved on the linkage member, and the two ends of the clamping elastic member are respectively connected to the end of the linkage member away from the measuring head and the base, and the clamping elastic member is used to drive the measuring head to abut against the workpiece through the linkage member; and a gauge is connected to the end of the linkage member away from the measuring head, and is used to measure the dimensions of the feature structure of the workpiece according to the distance the measuring head moves driven by the linkage member when the moving slide table drives the workpiece to slide.

[0006] In some embodiments, the base has a second slide groove on its side wall facing the movable slide table. The second slide groove extends along the sliding direction of the linkage member. The linkage member is slidably disposed in the second slide groove. One end of the clamping elastic member is connected to the end of the linkage member away from the measuring head, and the other end of the clamping elastic member is inserted into the second slide groove.

[0007] In some embodiments, the measuring device further includes a pusher disposed on the linkage and extending out of the second slide groove, the pusher being used to drive the measuring head to separate from the workpiece via the linkage.

[0008] In some embodiments, the measuring device further includes a pushing assembly, which includes: a cover member disposed on the base and covering the second slide groove, the cover member having a guide groove extending along the extension direction of the second slide groove and communicating with the second slide groove, the push member passing through the guide groove and protruding from the side of the cover member away from the base; and a pushing member disposed on the cover member and located on the side of the push member away from the limiting member, the pushing member being used to push the push member toward the limiting member, so that the push member drives the measuring head to separate from the workpiece through the linkage member.

[0009] In some embodiments, the pushing member includes: a pushing portion rotatably disposed on the cover and abutting against the pushing member, the pushing portion being an eccentric cam structure; an extension portion, one end of which is connected to the pushing portion and the other end of which extends in a direction perpendicular to the rotation axis of the pushing portion; and a handle portion disposed at the other end of the extension portion for driving the pushing portion to rotate through the extension portion so that the pushing portion abuts against the pushing member.

[0010] In some embodiments, the extrusion assembly includes: a support member disposed on the movable slide, the support member having a sliding hole extending along the sliding direction of the linkage member; an extrusion member slidably disposed in the sliding hole; a closing member disposed on the support member and closing one end of the sliding hole away from the limiting member; and an extrusion elastic member disposed in the sliding hole, with both ends connected to the closing member and the extrusion member respectively, for driving the extrusion member to extrude the workpiece.

When measuring the dimensions of a workpiece's feature structure, the workpiece is placed on the movable slide, with the limiting member abutting against it. The pressing assembly clamps the workpiece against the limiting member. The clamping elastic member, through the linkage member, drives the measuring head to abut against the side wall of the workpiece near the feature structure. The movable slide then moves the workpiece, bringing the measuring head into contact with the corresponding position of the feature structure. At this point, the gauge obtains the distance the measuring head has moved, which is the dimension of the workpiece's feature structure. Because the measuring head is small, it can fully contact small-sized feature structures, thus meeting the measurement requirements for small-sized feature structures. Furthermore, the method of obtaining the workpiece's feature structure dimension using the gauge based on the distance the measuring head has moved, driven by the linkage member, offers high measurement accuracy, thereby reducing measurement errors.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0023] Please see Figure 1 and Figure 2 This application provides a measuring device 100 for measuring the dimensions of a feature structure 210 of a workpiece 200. The workpiece 200 can be the mid-frame, bottom shell, or display module of an electronic product such as a mobile phone or tablet computer, and the feature structure 210 can be a blind hole, keyway, or protrusion. For ease of understanding, this application uses the mid-frame of a mobile phone as an example, with a blind hole as the feature structure 210; however, this is not intended to limit the scope of this application.

[0024] In this embodiment, the measuring device 100 includes a base 10, a movable slide 20, a limiting member 31, a pressing assembly 40, a linkage member 50, a measuring head 60, a pressing elastic member 70, and a gauge 80.

[0025] The movable slide 20 is slidably mounted on the base 10 and is used to support the workpiece 200. The limiting member 31 is mounted on the movable slide 20 and is used to abut against and limit the workpiece 200.

[0026] The extrusion assembly 40 is disposed on the movable slide 20 and spaced apart from the limiting member 31. The arrangement direction of the extrusion assembly 40 and the limiting member 31 is perpendicular to the sliding direction of the movable slide 20. The extrusion assembly 40 is used to press the workpiece 200 against the limiting member 31.

[0027] The linkage 50 is slidably disposed on the base 10 along the arrangement direction of the extrusion assembly 40 and the limiting member 31. The measuring head 60 is connected to the end of the linkage 50 near the limiting member 31 and extends to the side of the limiting member 31 away from the extrusion assembly 40.

[0028] The clamping elastic element 70 is sleeved on the linkage 50. The clamping elastic element 70 can be a spring. The two ends of the clamping elastic element 70 are respectively connected to the end of the linkage 50 away from the measuring head 60 and the base 10. The clamping elastic element 70 is used to drive the measuring head 60 to abut against the workpiece 200 through the linkage 50.

[0029] The gauge 80 is connected to the end of the linkage 50 away from the measuring head 60. The gauge 80 is used to measure the size of the feature structure 210 of the workpiece 200 based on the distance the measuring head 60 moves driven by the linkage 50 when the moving slide 20 drives the workpiece 200 to slide.

[0030] When measuring the dimensions of the feature structure 210 of workpiece 200 using measuring device 100, workpiece 200 is placed on movable slide 20, with limiting member 31 abutting against and limiting workpiece 200. Extrusion assembly 40 presses workpiece 200 firmly against limiting member 31. Extrusion elastic member 70, via linkage member 50, drives measuring head 60 to abut against the side wall of workpiece 200 near feature structure 210. Then, sliding slide 20 moves workpiece 200 and moves measuring head 60 into feature structure 210. At this time, extrusion elastic member 70, via linkage member 50, drives measuring head 60 to abut against the bottom of feature structure 210. Gauge 80 obtains the distance the linkage member 50 drives the measuring head 60 to move, thus obtaining the dimensions of feature structure 210 of workpiece 200. Because the measuring head 60 is small, it can fully contact the small-sized feature structure 210. Therefore, the measuring device 100 of this embodiment can meet the measurement requirements of small-sized feature structures 210. In addition, the measurement accuracy is high by using gauge 80 to obtain the size of the feature structure 210 of workpiece 200 by moving the measuring head 60 by linkage 50, thereby reducing measurement error.

[0031] Understandably, in this embodiment, the size of the feature structure 210 refers to the depth or thickness of the feature structure 210. In some other embodiments, when the feature structure 210 has other shapes, the size of the feature structure 210 may also be the length or width of the feature structure 210, and this application embodiment does not specifically limit this.

[0032] In this embodiment, gauge 80 is a mechanical micrometer. Mechanical micrometers are inexpensive and accurate, thus reducing costs and improving the accuracy of measuring the dimensions of the feature structure 210 of workpiece 200. It should be noted that mechanical micrometers require setting a reference value each time they are used, such as zeroing.

[0033] In other embodiments, the gauge 80 may also be a digital micrometer with a built-in absolute measurement mode or other measuring instruments that do not require setting a reference value for each measurement. This application embodiment does not specifically limit this.

[0034] In this embodiment, the measuring device 100 further includes a reference member 32, which is movably disposed on the movable slide 20 and located between the limiting member 31 and the extrusion assembly 40. The base 10 is used to abut against the measuring head 60 to set the reference value of the gauge 80.

[0035] By setting the reference piece 32, when using the measuring device 100 to measure the dimensions of the feature structure 210 of the workpiece 200, the reference piece 32 is first placed on the movable slide 20, so that the limiting piece 31 abuts against the limiting reference piece 32. The pressing assembly 40 presses the reference piece 32 against the limiting piece 31. The pressing elastic piece 70 drives the measuring head 60 to abut against the reference piece 32 through the linkage piece 50. At this time, the gauge 80 is zeroed, or the displayed value of the gauge 80 is observed and recorded as the reference value. Then the reference piece 32 is removed, the workpiece 200 is placed on the movable slide 20, and the dimensions of the feature structure 210 of the workpiece 200 are measured according to the above measurement process. If the gauge 80 is zeroed when using the reference piece 32, the displayed value of the gauge 80 at the end of the measurement is the dimension of the feature structure 210 of the workpiece 200. If the displayed value of the gauge 80 is recorded as the reference value when using the reference piece 32, the value obtained by subtracting the reference value from the displayed value of the gauge 80 at the end of the measurement is the dimension of the feature structure 210 of the workpiece 200. In this way, the setting of the reference piece 32 improves the convenience of setting the reference value of the gauge 80 and improves the accuracy of the measuring device 100 in measuring the dimension of the feature structure 210 of the workpiece 200.

[0036] In this embodiment, the reference component 32 is a zeroing block. In some other embodiments, the reference component 32 may also be a standard component with the same structure as the workpiece 200, and this application does not specifically limit this.

[0037] In this embodiment, a first slide groove 11 is provided on the side wall of the base 10 facing the movable slide 20. The first slide groove 11 extends along the sliding direction of the movable slide 20, and the movable slide 20 is slidably disposed in the first slide groove 11.

[0038] By setting the first slide groove 11, the accuracy of the sliding of the movable slide table 20 on the base 10 is improved, and the accuracy of the measuring device 100 in measuring the dimensions of the feature structure 210 of the workpiece 200 is also improved.

[0039] In this embodiment, a second slide groove 12 is provided on the side wall of the base 10 facing the movable slide table 20. The second slide groove 12 extends along the sliding direction of the linkage 50. The linkage 50 is slidably disposed in the second slide groove 12. One end of the pressing elastic member 70 is connected to the end of the linkage 50 away from the measuring head 60, and the other end of the pressing elastic member 70 is inserted into the second slide groove 12.

[0040] By setting the second slide groove 12, the accuracy of the clamping elastic element 70 driving the measuring head 60 to move through the linkage element 50 is improved, and the accuracy of the measuring device 100 in measuring the dimensions of the feature structure 210 of the workpiece 200 is also improved.

[0041] In this embodiment, a stop protrusion 51 is provided along the circumference of the end of the linkage 50 away from the measuring head 60. One end of the pressing elastic member 70 abuts against the stop protrusion 51, and the other end of the pressing elastic member 70 is stopped in the second sliding groove 12. This improves the convenience of installing the pressing elastic member 70 and improves the accuracy of the pressing elastic member 70 driving the measuring head 60 to move through the linkage 50.

[0042] Please refer to the following: Figure 3 In this embodiment, the extrusion assembly 40 includes a support member 41, an extrusion member 42, a closing member 43, an extrusion elastic member 44, and a connecting bolt 45. The support member 41 is disposed on the movable slide table 20 and has a sliding hole 411 extending along the sliding direction of the linkage member 50. The extrusion member 42 is slidably disposed in the sliding hole 411. The closing member 43 is disposed on the support member 41 and closes the end of the sliding hole 411 away from the limiting member 31. The connecting bolt 45 passes through the closing member 43 and connects to the support member 41, thereby fixing the closing member 43 to the support member 41. The extrusion elastic member 44 can be a spring, disposed within the sliding hole 411, with both ends connected to the closing member 43 and the extrusion member 42 respectively. The extrusion elastic member 44 is used to drive the extrusion member 42 to extrude the workpiece 200.

[0043] When the extrusion assembly 40 presses the workpiece 200 onto the limiting member 31, the extrusion elastic member 44 drives the extrusion member 42 to press the workpiece 200. The sliding hole 411 guides the movement direction of the extrusion member 42, thereby improving the accuracy and stability of the extrusion assembly 40 pressing the workpiece 200 onto the limiting member 31.

[0044] In this embodiment, the cross-sectional dimension of the end of the extruder 42 away from the closure member 43 gradually decreases in the direction away from the closure member 43. This helps to reduce the contact area between the extruder 42 and the workpiece 200, thereby effectively preventing the large friction between the extruder 42 and the workpiece 200 from affecting the movement of the movable slide 20 in driving the workpiece 200.

[0045] Please refer to it again. Figure 1 and Figure 2 In this embodiment, the measuring head 60 includes a connecting portion 61 and a probe portion 62. The movable slide 20 has a clearance opening 21, which is located on the side of the limiting member 31 away from the compression assembly 40. The connecting portion 61 is connected to the linkage member 50 and passes through the clearance opening 21. The probe portion 62 is connected to the end of the connecting portion 61 away from the linkage member 50 and extends towards the gauge 80 along the sliding direction of the linkage member 50. Because the probe portion 62 is small in size, it can fully contact the small-sized feature structure 210, thereby enabling the measuring device 100 to further meet the measurement requirements of the small-sized feature structure 210.

[0046] In this embodiment, the measuring device 100 further includes a stop 33, which is disposed on the movable slide 20 and located on one side of the limiting member 31. The stop 33 is used to abut against the limiting workpiece 200 along the sliding direction of the movable slide 20.

[0047] When the measuring device 100 measures the dimensions of the feature structure 210 of the workpiece 200, the limiting member 31 and the stop member 33 abut against the workpiece 200 from two mutually perpendicular directions, thereby improving the accuracy of the measuring device 100 in measuring the dimensions of the feature structure 210 of the workpiece 200.

[0048] In this embodiment, the measuring device 100 further includes a plurality of positioning members 34. The plurality of positioning members 34 are spaced apart on opposite sides of the movable slide 20 along the sliding direction of the movable slide 20 and are movably inserted into the base 10. The plurality of positioning members 34 are used to abut against and limit the movable slide 20.

[0049] When the workpiece 200 is placed on the movable slide 20, the positioning member 34 abuts against the movable slide 20 and is limited, so that the position of the measuring head 60 abutting against different workpieces 200 is approximately the same, thereby improving the accuracy of the measuring device 100 in measuring the dimensions of the feature structure 210 of the workpiece 200. In addition, by setting the positioning member 34 to be movably inserted into the base 10, it is easy to assemble and disassemble the positioning member 34 as needed.

[0050] In this embodiment, when the workpiece 200 is placed on the movable slide 20, the positioning member 34 located on one side of the movable slide 20 abuts against and limits the movable slide 20. The movable slide 20 can drive the workpiece 200 to move toward the positioning member 34 located on the other side of the movable slide 20. The positioning members 34 located on both sides of the movable slide 20 limit the distance the movable slide 20 can move.

[0051] In some other embodiments, when the workpiece 200 is placed on the movable slide 20, the positioning members 34 located on both sides of the movable slide 20 abut against and restrict the movable slide 20. When the movable slide 20 moves the workpiece 200, the positioning members 34 are removed from the base 10, thereby releasing the restriction on the movable slide 20. This application embodiment does not specifically limit this.

[0052] In this embodiment, the measuring device 100 further includes a pusher 91, which is disposed on the linkage 50 and extends out of the second slide groove 12. The pusher 91 is used to drive the measuring head 60 to separate from the workpiece 200 through the linkage 50.

[0053] When the workpiece 200 is placed between the extrusion assembly 40 and the limiting member 31, and when the inspected workpiece 200 is removed, the linkage member 50 can be driven by the pusher 91 to move the measuring head 60 away from the extrusion assembly 40, thereby facilitating the picking and placing of the workpiece 200.

[0054] In this embodiment, the measuring device 100 further includes a pushing assembly 92, which includes a cover member 921 and a pushing member 922. The cover member 921 is disposed on the base 10 and covers the second slide groove 12. The cover member 921 has a guide groove 9211, which extends along the extension direction of the second slide groove 12 and communicates with the second slide groove 12. The pushing member 91 passes through the guide groove 9211 and protrudes from the side of the cover member 921 away from the base 10. The pushing member 922 is disposed on the cover member 921 and is located on the side of the pushing member 91 away from the limiting member 31. The pushing member 922 is used to push the pushing member 91 toward the limiting member 31, so that the pushing member 91 drives the measuring head 60 to separate from the workpiece 200 through the linkage member 50.

[0055] When the workpiece 200 is placed between the extrusion assembly 40 and the limiting member 31, and when the inspected workpiece 200 is removed, the pushing member 922 pushes the pushing member 91 toward the limiting member 31. The pushing member 91 drives the measuring head 60 to move away from the extrusion assembly 40 through the linkage member 50, thereby improving the convenience of picking up and placing the workpiece 200.

[0056] In this embodiment, the pushing member 922 includes a pushing portion 9221, an extension portion 9222, and a handle portion 9223. The pushing portion 9221 is rotatably mounted on the cover member 921 and abuts against the pushing member 91. The pushing portion 9221 has an eccentric cam structure. One end of the extension portion 9222 is connected to the pushing portion 9221, and the other end of the extension portion 9222 extends in a direction perpendicular to the rotation axis of the pushing portion 9221. The handle portion 9223 is located at the other end of the extension portion 9222. The handle portion 9223 is used to drive the pushing portion 9221 to rotate via the extension portion 9222, so that the pushing portion 9221 pushes against the pushing member 91.

[0057] When the workpiece 200 is placed between the extrusion assembly 40 and the limiting member 31, and when the inspected workpiece 200 is removed, force is applied to the handle 9223 to cause the handle 9223 to drive the pushing part 9221 to rotate through the extension 9222. Since the pushing part 9221 is an eccentric cam structure, the pushing part 9221 pushes the pusher 91 to move toward the limiting member 31. The pusher 91 drives the measuring head 60 to move away from the extrusion assembly 40 through the linkage 50, thereby further improving the convenience of picking up and placing the workpiece 200.

[0058] In other embodiments, the pushing member 922 may also be a power component such as a cylinder or an electric push rod, and this application does not specifically limit this.

[0059] In summary, the measuring device 100 of this application embodiment comprises a base 10, a movable slide 20, a limiting member 31, a pressing assembly 40, a linkage member 50, a measuring head 60, a pressing elastic member 70, and a gauge 80. When the measuring device 100 measures the dimensions of the feature structure 210 of the workpiece 200, the workpiece 200 is placed on the movable slide 20, the limiting member 31 abuts against and limits the workpiece 200, the pressing assembly 40 presses the workpiece 200 against the limiting member 31, and the pressing elastic member 70 drives the measuring head 60 to abut against the side wall of the workpiece 200 near the feature structure 210 via the linkage member 50. Then, the movable slide 20 is slid to move the workpiece 200 and make the measuring head 60 contact the corresponding position of the feature structure 210. At this time, the gauge 80 can obtain the distance that the linkage member 50 drives the measuring head 60 to move, and this distance is the dimension of the feature structure 210 of the workpiece 200. Because the measuring head 60 is small in size, it can fully contact the small-sized feature structure 210. Therefore, the measuring device 100 of this embodiment can meet the measurement requirements of the small-sized feature structure 210. In addition, the measurement accuracy is high by using the gauge 80 to obtain the size of the feature structure 210 of the workpiece 200 based on the distance the measuring head 60 moves driven by the linkage 50, thereby reducing measurement errors.
