[embodiment]

In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.

embodiment 1:

The utility model example 1 provides a kind of flatness checking device.Refer to Fig. 1, Fig. 1 is the three-dimensional structure diagram of an embodiment of flatness checking device of the present utility model, and as shown in Figure 1, flatness checking device comprises slide rail 110 and glidepath 120, for detecting the flatness of part 200.

Fig. 2 is the three-dimensional structure diagram of part 200 shown in Fig. 1, and as shown in Figure 2, part 200 is here specially phone housing.This phone housing 200 comprises tested surface 210 on, and particularly, on this, tested surface 210 is the face interlocked with miscellaneous part during phone housing 200 uses, and therefore this surface generally needs higher planarity requirements.

Fig. 3 is the three-dimensional structure diagram of upper slide rail 110 shown in Fig. 1, and as shown in Figure 3, in order to realize measurement plane degree, the bottom of upper slide rail 110 is provided with upper groove 111, and upper groove 111 bottom surface comprises detection plane 111a on.Fig. 4 is the perspective view of glidepath 120 shown in Fig. 1, and as shown in Figure 4, the top of glidepath 120 is provided with low groove 121.Fig. 5 is glidepath in Fig. 1 120 and upper slide rail 110 unitized construction schematic diagram, composition graphs 1 and Fig. 5 can find out, the top of glidepath 120 and the bottom of upper slide rail 110 interlock, and now the low groove 121 of glidepath 120 forms hollow region 140 with the upper groove 111 of upper slide rail 110.

As shown in Figure 1, when part 200 is positioned on glidepath 120, upper tested surface 210 matches with upper detection plane 111a, the gap width that such as the two setting is certain.When the flatness of upper tested surface 210 meets the requirements, upper tested surface 210 more smooth, tested surface 210 can be allowed to slip over from upper detection plane 111a surface, and part 200 now can pass through hollow region 140.On the contrary, when the flatness of upper tested surface 210 is undesirable, due to the out-of-flatness of upper tested surface 210, upper tested surface 210 can not slip over from upper detection plane 111a surface, and part 200 is not now by hollow region 140.Therefore, the flatness checking device in the utility model embodiment directly need not go the flatness measuring tested surface, and just can detect whether the flatness of part 200 meets the requirements expeditiously.

In the present embodiment, part 200 is the consistent parts of Width, and accordingly, hollow region 140 is the consistent structure of width.The part 200 of this structure slides in hollow region 140 than being easier to, and hollow region 140 also can detect the width consistency of part 200 simultaneously, is one preferably structure.

Part 200 in the present embodiment also comprises tested surface, and lower tested surface is here in particular the back side of phone housing.Lower tested surface and upper tested surface 210 parallel to each other, simultaneously the low groove 121 of glidepath 120 comprises detection plane 121a, and when part 200 is by hollow region, lower tested surface slips over from lower detection plane 121a.In like manner, the flatness checking device in the present embodiment can detect the flatness of lower tested surface 210 simultaneously, also the indirect detection height of part 200.

In addition, as shown in Figure 2, the surface of phone housing 200 has some projections 220, in order to ensure that projection 220 does not hinder phone housing 200 to slide between upper slide rail 110 and glidepath 120 in testing process, as shown in Figure 3, the upper detection plane 111a of upper slide rail 110 is provided with some sliding tray 111b, and when sliding to make phone housing 200, projection 220 can be moved by sliding tray 111b.

In order to fixing upper slide rail 110 and glidepath 120, upper slide rail 110 comprises 6 threaded holes 113, glidepath 120 then comprises 6 threaded holes 122, threaded hole 113 mates one by one with threaded hole 122, cooperatively interact, upper slide rail 110 can be bolted like this with glidepath 120, is convenient to processing and the assembling of the two like this.It is easily understood that in other embodiments of the present utility model, quantity and the position of the threaded hole of upper slide rail 110 and glidepath 120 can be arranged as required, are not limited in the present embodiment and illustrate.

As shown in Figure 1, flatness checking device also comprises a support 130, this support 130 is positioned at slide rail 110 and the bottom of glidepath 120, makes slide rail 110 and glidepath 120 keep tilting, phone housing 200 can be made to rely on gravity down landing from glidepath 120.

Certainly it is easily understood that the phone housing 200 in the present embodiment is a kind of example, other the part flatness checking device can applied in the present embodiment carrys out detection plane degree.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
