[0025] like Figure 1-4 As shown, this application embodiment provides a mobile phone plastic frame side hole position gauge, including a base plate 1, a plurality of support members 14 are provided on the surface of the base plate 1, the support members 14 are used to support the workpiece, the base plate 1 is also provided with a first positioning member 11 and a second positioning member 12, and the first positioning member 11 and the second positioning member 12 are arranged opposite to each other;

[0026] The measuring component 3 is provided in several groups. The measuring component 3 is installed on the base plate 1 through the mounting part 4, and the measuring component 3 is arranged on the periphery of the support part 14.

[0027] The pressure plate 2 is correspondingly arranged with the support member 14. The pressure plate 2 has a first positioning hole 21 and a second positioning hole 22. When the first positioning member 11 is inserted into the first positioning hole 21 and the second positioning member 12 is inserted into the second positioning hole 22, the base plate 1 and the pressure plate 2 cooperate to clamp and position the workpiece.

[0028] In this embodiment, each support member 14 is detachably installed on the base plate 1 by bolts. The first positioning member 11 and the second positioning member 12 are columnar, and the cross-sectional shape of the first positioning member 11 and the second positioning member 12 is circular. Optionally, the cross-sectional shape of the first positioning member 11 and the second positioning member 12 can also be a regular polygon or an ellipse. Optionally, the first positioning member 11 and the second positioning member 12 are arranged diagonally. The pressure plate 2 can cooperate with the base plate 1 to clamp and position the plastic frame.

[0029] During operation, the workpiece is first placed on the floor, and then the support member 14 on the base plate 1 supports the workpiece. Then, the pressure plate 2 is pressed on the support member 14 and the workpiece. During the pressing process of the pressure plate 2, the first positioning member 11 will gradually insert into the first positioning hole 21 and the second positioning member 12 will gradually insert into the second positioning hole 22. At this time, the rapid positioning of the pressure plate 2 is completed. When the pressure plate 2 and the base plate 1 clamp the workpiece, the support member 14 can be used to correct and position the workpiece and adjust the position of the workpiece. After the pressure plate 2 and the base plate 1 have completed the clamping and positioning of the workpiece, the measuring component 3 is used for measurement.

[0030] By setting up a pressure plate 2, the pressure plate 2 can cooperate with the base plate 1 to clamp the workpiece. The first positioning element 11 and the second positioning element 12 set on the base plate 1, as well as the first positioning hole 21 and the second positioning hole 22 set on the pressure plate 2, can position and adjust the workpiece when the pressure plate 2 and the base plate 1 clamp the workpiece. The structure is simple and can effectively improve work efficiency.

[0031] The inspection tool provided in this application can quickly inspect products processed on-site, reducing the number of 2.5D and 3D measurements and lowering the product size NG scrap rate.

[0032] In one embodiment, the measuring component 3 includes a measuring element 31 and a pushing element 32. The mounting component 4 has a through hole adapted to the measuring element 31. One end of the measuring element 31 is movably inserted into the through hole, and the other end of the measuring element 31 is connected to the pushing element 32.

[0033] In this embodiment, the position and number of measuring components 31 correspond to the position and number of button mounting holes, sound holes or headphone and data cable plug holes in the middle frame of the mobile phone. The measuring components 31 are rod-shaped, and the cross-sectional shape of the measuring components 31 matches the shape and size of the button mounting holes, sound holes or headphone and data cable plug holes. The mounting component 4 is detachably mounted on the base plate 1, and the moving push component 32 can drive the measuring components 31 to slide in the through hole.

[0034] During operation, after the mobile phone frame is clamped and positioned by the pressure plate 2 and the base plate 1, the moving pusher 32 causes one end of the measuring member 31 inserted into the through hole to approach the button mounting hole, sound hole, or headphone and data cable jack on the mobile phone frame, so that the position of the mobile phone frame can be measured.

[0035] In one embodiment, a fixing component is provided between the base plate 1 and the pressure plate 2, the fixing component being used to keep the base plate 1 and the pressure plate 2 clamping and positioning the workpiece.

[0036] In this embodiment, by setting a fixing component, when measuring the position of the mobile phone frame, no manual operation is required, and the base plate 1 and the pressure plate 2 can keep the mobile phone frame clamped, which helps to improve work efficiency.

[0037] In one embodiment, the fixing component includes a plurality of first magnetic elements 13 and second magnetic elements 23. The first magnetic elements 13 are disposed on the base plate 1, and the second magnetic elements 23 are disposed on the pressure plate 2. The magnetic poles of the first magnetic elements 13 and the second magnetic elements 23 are opposite.

[0038] In this embodiment, the first magnetic element 13 and the second magnetic element 23 are permanent magnets or electromagnets. The number of the first magnetic elements 13 on the base plate 1 is the same as the number of the second magnetic elements 23 on the pressure plate 2. After the pressure plate 2 and the base plate 1 clamp the workpiece, the positions of the first magnetic elements 13 and the second magnetic elements 23 are set accordingly.

[0039] After the pressure plate 2 and the base plate 1 have completed the clamping and positioning of the workpiece, a magnetic attraction force will be generated between the first magnetic element 13 and the second magnetic element 23. At this time, the pressure plate 2 is not easy to detach from the base plate 1, so that the pressure plate 2 and the base plate 1 maintain the clamping state of the workpiece.

[0040] In one embodiment, the shape and size of the first positioning member 11 are adapted to the first positioning hole 21, and the shape and size of the second positioning member 12 are adapted to the second positioning hole 22. The diameter of the first positioning member 11 is larger than the diameter of the second positioning member 12.

[0041] In this embodiment, the first positioning member 11 and the second positioning member 12 can have different shapes and sizes. The purpose of this distinction is to facilitate the alignment of the first magnetic member 13 and the second magnetic member 23, and to prevent the first magnetic member 13 and the second magnetic member 23 from failing to align accurately during the pressing process of the pressure plate 2, thereby affecting the clamping effect of the base plate 1 and the pressure plate 2 on the mobile phone frame.

[0042] In one embodiment, a handle 24 is provided on the side of the pressure plate 2 away from the base plate 1.

[0043] In this embodiment, a handle 24 is provided on the pressure plate 2 to facilitate the removal of the pressure plate 2.
