[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1 As shown, the existing inspection rack contains multiple section templates to form the inspection shape. Its assembly method is to open two reference holes on each template, and each template is clamped and positioned by a screw and a nut at the front and back. Due to the gap in the bolt connection and the large tolerance, the manufacturing workers are required to have high skills in using the templates, which is easy to make mistakes, and the larger templates will bend.

[0021] like Figure 3-Figure 6 As shown, an embodiment of the utility model discloses a hyperbolic part inspection rack, which is used to inspect a hyperbolic part 2, and includes a plurality of section templates 1 with an "L"-shaped cross section, the plurality of section templates 1 are arranged in parallel, and one end of the plurality of section templates 1 can be detachably connected with the same first reinforcement structure;

[0022] The bottoms of the other ends of the plurality of section templates 1 are all detachably connected with the same second reinforcement structure.

[0023] The present embodiment can realize that the first reinforcement structure and the second reinforcement structure are detachably fixedly connected with a plurality of section templates to form a relatively stable inspection frame as a whole, and then the hyperbolic part is placed on the inspection frame. Figure 2 As shown, after being placed, the hyperbolic parts are inspected or processed. The inspection rack provided by this embodiment has good overall stability and high shape accuracy, which fully meets the requirements of part manufacturing and inspection and improves the quality of part processing.

[0024] In this embodiment, the first reinforcement structure includes two first reinforcement plates 30 arranged in parallel, and the two first reinforcement plates 30 are each provided with a plurality of first card slots 31 along their length direction, and a plurality of vertical sides of the cut surface templates 1 are each provided with a first slot 10 and a second slot 11, wherein the plurality of first card slots 31 of one first reinforcement plate 30 are plugged into the plurality of first slots 10 one by one;

[0025] The first card slots 31 of the other first reinforcing plate 30 are plugged into the second slots 11 one by one.

[0026] It should be noted that the positions of the first card slots on one first reinforcing plate correspond to the positions of the first slots, and the positions of the first card slots on another first reinforcing plate correspond to the positions of the second slots.

[0027] Through the above arrangement, the present embodiment can first insert the first first slot on one side of a first reinforcement plate into the first slot of the first cut surface template, and then insert the second first slot of the first reinforcement plate into the first slot of the second cut surface template, and then implement it in the same way, that is, insert the remaining first slots of the first reinforcement plate into the first slots of the corresponding cut surface templates in turn, so as to realize the detachable fixation of the first reinforcement plate to several cut surface templates.

[0028] Similarly, insert the first first slot on one side of another first reinforcement plate into the second slot of the first cut-surface template, and then insert the second first slot of the first reinforcement plate into the second slot of the second cut-surface template. The same process is repeated in sequence, that is, the remaining first slots of the first reinforcement plate are inserted into the second slots of other corresponding cut-surface templates in sequence, and finally the other first reinforcement plate is disassembled and fixed to several cut-surface templates.

[0029] In this embodiment, the second reinforcement structure includes two second reinforcement plates 40 arranged in parallel, and the two second reinforcement plates 40 are provided with a plurality of second card slots 41 extending vertically downward along their length direction, and the horizontal sides of the plurality of section templates 1 are provided with a third slot 12 and a fourth slot 13, wherein the plurality of second card slots 41 of one second reinforcement plate 40 are plugged into the plurality of third slots 12 one by one;

[0030] The second card slots 41 of the other second reinforcing plate 40 are plugged into the fourth slots 13 one by one.

[0031] It should be noted that the positions of the second card slots on one second reinforcing plate correspond to the positions of the third slots, and the positions of the first card slots on another second reinforcing plate correspond to the positions of the fourth slots.

[0032] Through the above arrangement, this embodiment can first insert the first second card slot on one side of a second reinforcing plate into the third slot of the first cut surface template, and then insert the second second card slot of the second reinforcing plate into the third slot of the second cut surface template. The same principle is followed, that is, the remaining second card slots of the second reinforcing plate are inserted into the third slots of the remaining corresponding cut surface templates, and finally the second reinforcing plate can be detachably fixed to a plurality of cut surface templates.

[0033] Similarly, insert the first second card slot on one side of another second reinforcement plate into the fourth slot of the first cut-surface template, and then insert the second second card slot of the second reinforcement plate into the fourth slot of the second cut-surface template. The same principle is implemented in sequence, that is, the remaining second card slots of the second reinforcement plate are inserted into the fourth slots of the remaining corresponding cut-surface templates in sequence, and finally another second reinforcement plate is detachably fixed to several cut-surface templates.

[0034] Through the above arrangement, this embodiment can realize the detachable fixing of the two first reinforcement plates and the two second reinforcement plates to the two ends of a plurality of section templates. Through the above combination, an inspection frame that can inspect hyperbolic parts is formed, and the inspection frame has good overall stability and high appearance accuracy, which fully meets the requirements of part manufacturing and inspection and improves the quality of part processing.
