Description

Technical Field

[0001] This utility model belongs to the field of flat panel back cover production technology, specifically relating to an internal dimension measuring fixture with positioning function. Background Technology

[0002] The back cover is the outer shell on the back of a tablet. Its main function is to protect internal components, such as circuit boards, batteries, and cameras, from external physical damage, such as impacts, scratches, and the intrusion of dust and liquids. At the same time, the back cover also provides structural support to the tablet, ensuring the relative stability of the internal components.

[0003] Tablet back covers typically have clearance holes on the side to expose the tablet buttons during assembly. To improve product quality, the internal dimensions of these clearance holes need to be measured to ensure that the tablet buttons are fully exposed. In current technology, the clearance holes are measured using a handheld micrometer and the tablet back cover. This method is not only inconvenient to operate, but its measurement accuracy is also easily affected by manual operation.

[0004] In view of this, the present invention provides an internal dimension measuring fixture with positioning function to meet the requirements. Utility Model Content

[0006] It also includes an internal micrometer that is movably mounted on the top surface of the base and located on one side of the positioning seat via a movable component. The end of the measuring contact of the internal micrometer is rotatably connected to an abutment block. When the abutment block is rotated open, the abutment block extends along the axial direction of the measuring contact of the internal micrometer to insert into a through hole opened on one side of the product to be measured opposite to the internal micrometer. The measuring surface of the measuring contact of the internal micrometer and the side of the abutment block on the same side are located in the same area.

[0007] As a preferred embodiment of the internal dimension measuring fixture with positioning function of this utility model, the movable component includes a clamping component disposed on the top surface of the base for fixing the internal micrometer, and a slide rail component disposed between the clamping component and the base for driving the clamping component to move.

[0008] As a preferred embodiment of the internal dimension measuring fixture with positioning function of this utility model, the slide rail assembly includes a first guide rail mounted on the top surface of the base, and a second guide rail slidably connected to the top of the first guide rail.

[0009] As a preferred embodiment of the internal dimension measuring fixture with positioning function of this utility model, the clamping assembly includes a base disposed on the top surface of the second guide rail, and a clamping portion connected to the top of the base.

[0010] As a preferred embodiment of the internal dimension measuring fixture with positioning function of this utility model, the extension direction of the first guide rail is parallel to the extension direction of one side of the product to be measured opposite to the internal micrometer.

[0011] As a preferred embodiment of the internal dimension measuring fixture with positioning function of this utility model, the product to be measured is a flat back cover, and at least one through hole is provided on one side opposite to the internal micrometer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model relates to an internal dimension measuring fixture with positioning function, such as... Figures 1-3 As shown, the device includes a base 1 and a positioning seat 2 connected to the top surface of the base 1 for positioning the product to be measured. It also includes an internal micrometer 8 movably mounted on the top surface of the base 1 and located on one side of the positioning seat 2 via a movable component. An abutment block 9 is rotatably connected to the measuring end of the internal micrometer 8, i.e., the end of the measuring contact. The abutment block 9 is rotatably connected to the measuring end of the internal micrometer 8 in the most common shaft connection in the current technology. When the abutment block 9 is rotated open, it can be inserted into a through hole (avoidance hole) opened on one side of the product to be measured opposite to the internal micrometer 8. The measuring surface of the measuring contact of the internal micrometer 8 and the side of the abutment block 9 on the same side are located in the same area, so as to realize the accurate measurement of the dimensions inside the through hole (avoidance hole) opened on the side of the product to be measured.

[0025] Specifically: such as Figure 4 As shown, the movable components include a clamping assembly disposed on the top surface of the base 1 for fixing the internal micrometer 8, and a slide rail assembly disposed between the clamping assembly and the base 1 for driving the clamping assembly to move. The slide rail assembly includes a first guide rail 4 mounted on the top surface of the base 1, and a second guide rail 5 slidably connected to the top of the first guide rail 4. The extension direction of the first guide rail 4 is parallel to the extension direction of one side of the product to be measured opposite to the internal micrometer 8, that is, the side of the product to be measured with a through hole (avoidance hole). The clamping assembly includes a base 6 fixed to the top surface of the second guide rail 5 by fasteners such as bolts, and a clamping part 7 fixed to the top of the base 6 by fasteners such as bolts. Grooves adapted to the periphery of the frame of the internal micrometer 8 are provided on the opposing surfaces between the base 6 and the clamping part 7. A soft pad, such as a rubber pad, is adhered in the groove. When the internal micrometer 8 is placed in the groove, the clamping between the base 6 and the clamping part 7 achieves the fixation of the internal micrometer 8.

[0026] In practical use, such as Figure 6 As shown, taking the back cover 10 of the flat panel as an example, it has a clearance hole (through hole) on one side for the flat panel buttons to pass through. The back cover 10 is fitted onto the corresponding positioning seat 2. It should be noted that when the back cover 10 is fixed in place, the side with the clearance hole (through hole) is opposite to the internal micrometer 8. By pushing the internal micrometer 8, it slides to the clearance hole (through hole). At this time, the abutment block 9 is rotated open. Figure 5 As shown, the abutment block 9 is inserted into the clearance hole (through hole). By rotating the micrometer drum of the internal measuring micrometer 8, the two measuring contacts on it can move towards or away from each other, so that the two abutment blocks 9 abut against the inner walls of both ends of the clearance hole (through hole) to achieve the measurement of its inner dimension length. It should be noted that as long as the abutment block 9 can be rotated into the clearance hole (through hole), it means that its height dimension is qualified, otherwise it is unqualified. Therefore, the height of the abutment block 9 is the same as the qualified height dimension of the clearance hole (through hole).

[0027] The clearance hole mentioned in this embodiment is a through hole; the through hole is also a clearance hole.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
