Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 to 3, a portable case front liner plate profile tolerance detection tool comprises a bottom plate 1, an edge positioning angle 2, a main groove detection datum 3, a key groove lower detection datum 5 and a key groove upper detection datum 6; the side positioning angles 2, the main groove detection datum 3 and the key groove pressing-down detection datum 5 are all located on the upper end face of the bottom plate 1, the bottom plate 1 is further provided with a detection column 4, the main groove detection datum 3, the detection column 4 and the key groove pressing-down detection datum 5 are all located in an area defined by the four side positioning angles 2, the key groove pressing-up detection datum 6 is movably connected with the key groove pressing-down detection datum 5, the main groove detection datum 3 is used for providing a positioning datum for detecting the profile tolerance of the main through groove, and the key groove pressing-down detection datum 5 is used for providing a positioning datum for detecting the profile tolerance of the key groove pressing-down profile side wall; detect 5 tops of benchmark according to the keyway and be provided with slot 51, detect benchmark 6 according to the keyway and include benchmark board 61, picture peg 63 and interior spring 65, benchmark board 61 detects for the profile tolerance of profile lateral wall on the key groove and provides the location benchmark, and interior spring 65 that props is forced when picture peg 63 inserts slot 51 and is out of shape, and then increases frictional force.

The slot 51 at the top end of the key slot pressing lower detection reference 5 is in a straight line shape, and the plug board 63 of the key slot pressing upper detection reference 6 is matched with the slot 51; the inner supporting spring 65 is specifically positioned in the abdicating groove 64 on the side surface of the inserting plate 63.

The side of the inside stay spring 65 outside protrusion picture peg 63, the length direction of inside stay spring 65 is unanimous and equal vertical setting with the extending direction of the groove 64 of stepping down.

The profile of the reference plate 61 of the detection reference 6 on the key groove is larger than the profile of the detection reference 5 under the key groove, the upper end of the reference plate 61 is provided with a handle 62, and the handle is used for conveniently holding the detection reference 6 on the key groove.

Limit location angle 2 is L shape for four corners department to being rectangular preceding welt work piece fixes a position, the king-groove detects benchmark 3 and is the cuboid form, detect the vertical setting of post 4 and be the linear array form and arrange, detect post 4 and be used for detecting the lamp hole on the preceding welt work piece.

The key pressing groove on the front lining plate workpiece is a countersunk groove and comprises an upper profile and a lower profile, and the two profiles are required to be subjected to profile tolerance detection; in order to ensure the smooth putting in of the front lining plate workpiece, the key groove upper detection datum 6 can be removed firstly and then installed during detection.

The utility model discloses a theory of operation does: firstly, taking down a key slot upper detection reference 6 from a key slot lower detection reference 5, then horizontally placing a portable case front lining plate to be detected into four side positioning angles 2, observing whether a convex main slot detection reference 3, a detection column 4 and the key slot lower detection reference 5 can interfere with the placing operation of a front lining plate workpiece, and if interference is generated, indicating that a main through slot, a lamp hole and a key slot on the front lining plate have larger position deviation or profile deviation; after the front lining plate workpiece is put in place, a plug gauge is used for detecting gaps between a main groove detection reference 3 and the inner wall of a main through groove and between a key groove lower detection reference 5 and the side wall of a key groove lower contour, so that whether the contour degree meets the requirement is detected; finally, the hand-held handle 62 inserts the picture peg 63 according to the detection benchmark 6 on the key groove downwards into the slot 51, and in the inserting process, the inner supporting spring 65 in the abdicating groove 64 deforms under the stress, so that the friction force between the picture peg 63 and the slot 51 is increased, the stability of the detection benchmark 6 on the key groove is enhanced, and at the moment, the plug gauge can be used for detecting the profile degree of the upper profile side wall of the key groove.
