Description
Technical Field
The utility model belongs to the technical field of aviation product assistance-localization real-time assembly, a can replace hand-held type layer board nut jig is related to, positioning error and margin assurance problem in can solving various layer board nut installation.
Background
In the assembly manufacturing process of aviation products, the location of layer board nut is an operation difficulty in the process flow, and its installation is puzzled a ray of workman always, and it is loaded down with trivial details to make the hole work through marking off location to positioning accuracy after making the hole also is difficult to guarantee, produces the not enough problem of margin easily. For the convenience of the workman to the layer board nut installation, the utility model designs a can replace hand-held type layer board nut jig to this improves workman's work efficiency, alleviates workman's intensity of labour, has also guaranteed the installation accuracy of layer board nut simultaneously.
SUMMERY OF THE UTILITY MODEL
The utility model provides a technical problem lie in providing the substitution jig that can guarantee margin to margin and positioning error for the mounting plate nut to solve the problem among the above-mentioned background art.
The utility model discloses a following technical scheme realizes:
a replaceable handheld support plate nut drill jig comprises a handheld drill 1, a drill bushing positioning pin 2, a replaceable drill bushing 3, a movable positioning pin 4, a bearing 5 and a supporting rod 6.
The handheld device 1 is mainly used for bearing a drill bushing positioning pin and a drill bushing, and bolt holes are formed in two ends of the handheld device; the handheld device 1 is designed to conform to the shape of ergonomics, so that the operation of workers is facilitated, and the labor intensity of the workers is reduced. The drill bushing positioning pin 2 is of a threaded screw rod structure, the drill bushing positioning pin with a corresponding size is selected according to the inner diameter of a bolt hole of a support plate nut, the threaded part of the drill bushing positioning pin 2 is screwed in the bolt hole of the hand-held device 1, and the replaceable drill bushing 3 is screwed and fixed on the drill bushing positioning pin 2 during work, so that the drill bushing is fixed with the hand-held device; the drill bushing positioning pin 2 extends out of the replaceable drill bushing 3 at the same time, and the extending part of the drill bushing positioning pin 2 is arranged in a supporting plate nut bolt hole of an original assembly part according to the coaxial principle of the hole, so that the supporting plate nut is accurately positioned. The outer ring of the bearing 5 is arranged in the drill bushing positioning pin 2 in an interference fit manner, and the inner ring of the bearing 5 is connected with one end of the supporting rod 6 in an interference fit manner, so that the supporting rod 6 can freely rotate along the axis of the bearing 5; the other end of the support rod 6 is provided with a movable positioning pin 4, and the movable positioning pin 4 is used for determining the position of the reference hole.
Furthermore, the replaceable drill bush 3 is of a single-lug structure or a double-lug structure and is selected according to requirements; the rivet hole is drilled by replacing the guide hole on the drill bushing 3 as a guide hole, so that the verticality of the rivet hole is ensured; meanwhile, the edge distance requirement of the supporting plate nut is guaranteed by utilizing the appearance structure of the replaceable drill bushing 3, and as shown in the figures 3 and 4, the supporting plate nut with the inner diameter phi of 6mm is guaranteed by adopting the replaceable drill bushing with the edge distance of 12 mm.
The utility model has the advantages that: can replace hand-held type layer board nut jig provide the system hole instrument when mounting of a layer board nut for the site operator, this instrument structure is fairly simple, the size is less, portable to in-process at the installation layer board nut can realize the accurate positioning fast, choose the drill bushing that freely changes for use, can realize the used repeatedly of the different specifications of drill bushing, and can utilize drill bushing appearance structure to realize the assurance to the margin.

Detailed Description
The following examples and drawings are provided to further explain the embodiments of the present invention, but are not intended to limit the present invention.
The method comprises the following steps: six parts, namely a handheld part 1, a drill bushing positioning pin 2, a replaceable drill bushing 3, a movable positioning pin 4, a bearing 5 and a supporting rod 6 are connected into a whole;
step two: the extended part of the drill bushing positioning pin 2 is placed into a manufactured screw hole to position a nut and bolt hole of a supporting plate, and the positioning and mounting accuracy is ensured by utilizing the principle that the three parts are coaxial;
step three: drilling a first positioning hole according to the position requirement, wherein the edge distance requirement can be ensured by depending on the appearance structure of the replaceable drill bushing 3 during drilling;
step four: the movable positioning pin 4 is taken up by hand, the supporting rod 6 is rotated to the positioning hole along the bearing 5, and the movable positioning pin 4 is put down to complete positioning;
step five: and drilling a second hole according to the replaceable drill bushing 3 to finish the drilling of the hole position of the supporting plate nut.
