Technical Field
The utility model relates to an installation mould, in particular to helicopter bottom plate embedding piece installation mould.
Background
When the embedded part is installed, a drill plate and a positioning pin are generally matched, and the positioning pin is inserted into a drilling position to enable the embedded part to be coaxial with the drill bushing. And injecting glue through the glue injection hole after the position of the embedded part is fixed. Because the thickness of the drilling template is limited, the positioning length of the embedded part is insufficient, and the installation verticality of the lower floor embedded part and the coaxiality of the lower floor embedded part and the upper floor embedded part are difficult to ensure.
Disclosure of Invention
The utility model discloses the technical problem who solves: provided is a mounting die capable of ensuring the positional accuracy of an insert.
The technical scheme of the utility model: a helicopter deck insert mounting die characterized by: the mounting die comprises an upper die plate 1, a lower die plate 2, a support 3, a positioning bolt 4 and a mounting inspection pin 5, the upper end and the lower end of the support 3 are respectively fixed with the upper die plate 1 and the lower die plate 2, the positioning bolt 4 is arranged on the lower die plate 2, coaxial through holes are formed in the upper die plate 1 and the lower die plate 2, and the mounting inspection pin 5 is located in the two through holes.
The utility model has the advantages that:
the insert mounting die simulates the distance between the upper and lower plates, increases the positioning length of the positioning pin, and effectively reduces the deviation caused by the inclination of the axis due to insufficient positioning length. In the manufacturing process of the mounting die, the coaxiality precision of the through holes of the upper die plate 1 and the lower die plate 2 is ensured, and the coaxiality precision of two positioning parts of the mounting positioning pin 5 is higher than the coaxiality requirements of the inserts in the upper die plate and the lower die plate, so that the coaxiality of the inserts of the upper die plate and the lower die plate is ensured to be within a limited tolerance range. The installation verticality of the lower floor embedded part is improved, the assembly precision is improved, and the requirement on the installation precision of the embedded part is met.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: 1 is the cope match-plate pattern, 2 is the lower bolster, 3 is the support, 4 is positioning bolt, 5 is the installation inspection round pin, 6 is the bush, 7 is the cylindric lock, 8 is the embedding piece, and 9 is the lower floor.
Detailed Description
The technical solution is further explained in detail with reference to the drawings.
The floor on the helicopter is generally divided into an upper layer and a lower layer, embedded parts are required to be installed in the upper layer floor and the lower layer floor, and the coaxiality requirement exists between the corresponding embedded parts. The perpendicularity of installation of the insert and the concentricity with the upper floor insert must be ensured during installation of the lower floor insert.
If only one jig plate and positioning pins are used to install the insert, the thickness of the jig plate is limited, typically about 10 mm. The positioning length of the positioning pin is insufficient, and due to human factors, the positioning pin cannot be inserted into the embedded part in a direction perpendicular to the floor, and vertical installation of the embedded part cannot be guaranteed. Due to the height between the upper and lower floor panels, the slight deviation of the angle of the axis of the lower floor panel insert also increases with distance, resulting in an inability to meet the concentricity requirements with the upper floor panel insert.
The insert mounting die is designed to simulate the distance between the upper and lower floor panels in order to ensure the mounting accuracy of the lower floor insert. The embedding piece installation mould comprises cope match-plate pattern 1, lower bolster 2, support 3, positioning bolt 4 and installation inspection round pin 5, and the upper and lower both ends of support 3 are fixed with cope match-plate pattern 1 and lower bolster 2 respectively, for improving rigidity, intensity and the stability of embedding piece installation mould, steel is all chooseed for use with template 1, template 2, installation inspection round pin 5 to support 3, and the distance between cope match-plate pattern 1 and the lower bolster 2 is the difference in height on upper floor and lower floor 9. Coaxial through holes are formed in the upper template 1 and the lower template 2, and the installation inspection pin 5 is positioned in the two through holes. The coaxiality of the two through holes and the coaxiality of the two positioning parts for mounting the inspection pin 5 are ensured in the manufacturing process. The support 3 is in interference fit with the two templates, and cylindrical pins are arranged on the parts, matched with the templates 1 and 2, of the support 3, so that the support 3 is prevented from rotating in the two templates. Be provided with positioning bolt 4 on lower bolster 2, the use:
1. and positioning the embedded part mounting die by using a positioning bolt according to the positioning hole of the lower floor. At the location of the bushing 6 of the lower formwork 2, i.e. the mounting location of the insert, a correspondingly sized quick-change drill bushing is inserted, and a pilot hole is drilled in the floor 9.
2. And after drilling, taking down the embedded part mounting die, reaming the hole at the initial hole position, and putting the embedded part into the hole after reaming.
3. And then positioning the insert mounting die by using the positioning bolts 4. Coaxial through holes are formed in the upper template 1 and the lower template 2, and the installation inspection pin 5 is inserted from a bushing 6 hole of the upper template 1 and passes through the bushing 6 hole of the lower template 2 to the inside of the embedded part.
4. After the embedded part is preliminarily fixed by the installation inspection pin 5, glue is injected into the embedded part by using the glue injection hole on the lower template 2, and then the embedded part is installed.
The insert mounting die simulates the height difference of an upper template and a lower template, and the coaxiality of the upper template and the lower template through holes and the coaxiality of two positioning parts of a mounting positioning pin are ensured, so that the coaxiality of the lower template insert and the upper floor insert meets the requirement of product tolerance. Meanwhile, the positioning length of the positioning pin is increased, so that the deviation caused by the inclination of the axis due to insufficient positioning length is effectively reduced. The mounting verticality of the lower floor embedded part is improved, and the precision requirement of the mounting position of the embedded part is met.
