Abstract
Description
Technical Field
[0001] This utility model relates to the field of drone fuselage forming, and in particular to a positioning fixture for aluminum parts of drone arms. Background Technology
[0002] In the process of mass-producing drone fuselages, a male mold with the same shape as the fuselage is first used to create a female mold. Then, the fuselage shell is made by casting the internal cavity of the female mold. Because the sockets of the drone arms need to be installed according to the movement direction of the drone arms, the aluminum socket parts for fixing the drone arms need to be manually installed and fixed to the fuselage shell by plugging them in to obtain the finished fuselage. The plugging installation method makes the aluminum socket parts of the drone arms prone to loosening. If the aluminum socket parts are connected to the fuselage shell as a whole during the fuselage shell forming process, it will be difficult to accurately position the socket direction. Therefore, a positioning tooling fixture is needed for the integral molding of the aluminum socket parts of the drone arms and the fuselage shell. Utility Model Content
[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a positioning fixture for aluminum parts of UAV arms, which has the advantages of high precision in manufacturing body holes, stable fixing of socket aluminum parts, and high versatility.
[0004] This utility model provides a positioning fixture for aluminum parts of a drone arm, which is used to fix the socket aluminum parts on a female mold to achieve the one-piece molding of the drone shell. The fixture includes a mold closing assembly. The female mold is provided with a shell molding cavity for filling the drone shell molding material. The side wall of the shell molding cavity has a channel for fixing the socket aluminum parts, and positioning screw holes are provided around the channel.
[0005] The mold assembly includes a fixed plate and a positioning block. The socket aluminum component includes a connecting ring and a plug ring, which are coaxially connected. The connecting ring is used to insert into the channel and connect to the housing molding material. The plug ring is used to connect to the drone arm. One side of the positioning block is detachably connected to the plug ring, and the connection method between the two is unique. The other side of the positioning block is detachably inserted into the fixed plate. The fixed plate has an opening corresponding to the positioning screw hole. The fixing direction of the socket aluminum component in the channel is determined by adjusting the direction of the positioning block when it is inserted into the fixed plate.
[0006] Furthermore, the inner longitudinal section of the plug ring is a rounded rectangle, and the shape of one side of the positioning block corresponds to the inner longitudinal section of the plug ring; the other side of the positioning block is a column with a square longitudinal section, and the fixing plate is provided with a channel for the column to be inserted.
[0007] Furthermore, a pad is provided on the side of the fixed plate near the female mold, and two of these pads are respectively provided on the left and right sides of the positioning block to determine the insertion depth of the connecting ring in the channel.
[0008] Furthermore, the tooling fixture also includes a male mold assembly for making the female mold. The female mold includes an upper mold and a lower mold. The upper mold and the lower mold are connected vertically to form a shell forming cavity for filling the shell forming material of the drone. The upper mold and the lower mold have a channel for fixing the socket aluminum parts at the connection point.
[0009] The male mold assembly includes a fuselage male mold, a mold closing baffle, and a positioning pin. The fuselage male mold has the same shape as the drone's shell. The side ring of the fuselage male mold is provided with a mold separating baffle that separates the upper mold and the lower mold, and an inner column that forms a channel. The inner column is provided with a positioning groove along the axial direction. One side of the positioning pin passes through the mold closing baffle and fits into the positioning groove. The mold closing baffle is provided with a pre-embedded nut that can form a positioning screw hole on the female mold.
[0010] Furthermore, the inner ring of the connector ring is provided with a connecting plate, on which a plug for transmitting signals from the drone arm is detachably fixed.
[0011] By adopting the above technical solution, the beneficial effects of this utility model are:
[0012] This invention achieves the fixing and positioning of the socket aluminum parts on the female mold by setting up a mold clamping assembly. The socket aluminum parts are erected by connecting the fixing plate to the female mold. The fixing direction of the positioning block on the fixing plate determines the fixing direction of the socket aluminum parts on the female mold. This makes the equipment universal for socket aluminum parts with different fixing directions, improves the applicability of the tool, and only requires changing the size of the positioning block when the size of the socket aluminum parts changes, reducing the overall tooling update and lowering production costs.
[0013] This invention uses a positioning groove on the male mold to cooperate with a positioning pin to determine the fixed position of the mold closing baffle. A pre-embedded nut on the mold closing baffle is used to form the positioning screw hole on the female mold. The mold closing baffle and the positioning pin are detachable and replaceable, which improves the overall application range. This invention achieves precise position determination and precise hole determination through various positioning blocks and positioning pins. The socket aluminum parts are integrally formed with the body shell to improve the connection strength between the two.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0039] This utility model is based on the molding process of a drone fuselage. First, a positive mold is carved according to the drone fuselage. Then, a negative mold 1 is printed on the surface of the positive mold by covering it with negative mold 1 material. Next, the socket aluminum part 3 is connected to the negative mold 1. Finally, the fuselage molding material is covered inside the negative mold 1 to complete the one-piece molding of the fuselage. (Refer to...) Figure 1-9 This utility model provides a positioning fixture for aluminum parts of a drone arm, which is used to fix the socket aluminum part 3 onto the female mold 1 to achieve one-piece molding of the drone shell. The female mold 1 is provided with a shell molding cavity for filling the drone shell molding material. The side wall of the shell molding cavity has a channel 11 for fixing the socket aluminum part 3, and positioning screw holes 12 are provided around the channel 11. The specific structure of the female mold 1 includes an upper mold and a lower mold. The upper mold and the lower mold are connected to form a shell forming cavity for filling the shell forming material of the drone. The upper mold and the lower mold have a channel 11 for fixing the socket aluminum part 3 at the connection. At this time, the aluminum part positioning fixture includes a male mold assembly 4 for making the female mold 1. The male mold assembly 4 includes a fuselage male mold 41, a mold closing baffle 42 and a positioning pin 43. The fuselage male mold 41 has the same shape as the drone shell. The side ring of the fuselage male mold 41 is provided with a mold separating baffle 44 that separates the upper mold and the lower mold and an inner column 45 that forms the channel 11. The inner column 45 is provided with a positioning groove 451 along the axial direction. One side of the positioning pin 43 passes through the mold closing baffle 42 and fits into the positioning groove 451. The mold closing baffle 42 is provided with a pre-embedded nut 421 for forming the positioning screw hole 12 on the female mold 1. At this time, the mold closing baffle 42 and the mold separating baffle 44 work together on the surface of the male mold 41 of the machine body to form a barrier that allows the female mold 1 to be formed, and the pre-embedded nut 421 provides a model for the forming of the positioning screw hole 12.
[0040] The socket aluminum part 3 includes a connecting ring 31 and a plug ring 32. The connecting ring 31 and the plug ring 32 are coaxially connected. The connecting ring 31 is used to insert into the channel 11 and connect to the housing molding material. The plug ring 32 is used to connect to the drone arm. The inner ring of the plug ring 32 is provided with a connecting plate 321. The plug 322 for signal transmission of the drone arm is detachably fixed on the connecting plate 321. After the socket aluminum part 3 is integrally formed with the body housing, the plug 322 is fixed on the connecting plate 321.
[0041] To fix the aluminum socket part 3 on the surface of the negative mold 1 after printing, the aluminum part positioning fixture also includes a mold closing assembly 2. The mold closing assembly 2 includes a fixing plate 21 and a positioning block 22. One side of the positioning block 22 is detachably connected to the insertion ring 32, and the connection method between the two is unique. Specifically, the inner longitudinal section of the insertion ring 32 is a rounded rectangle, which can be a pair of rounded rectangles with arc-shaped sides. The shape of one side of the positioning block 22 corresponds to the inner circle of the insertion ring 32. The other side of the positioning block 22 is a column with a square longitudinal section. The fixing plate 21 is provided with a channel 212 for the column to be inserted. The square body determines that the positioning block 22 can only be adjusted in a 90° direction on the fixing plate 21. At this time, the position of the aluminum socket part 3 can also only be adjusted in a 90° direction, which improves the adjustment accuracy. The other side of the positioning block 22 can be detachably inserted into the fixing plate 21. The fixing plate 21 has an opening 211 corresponding to the positioning screw hole 12. The opening 211 is aligned with the positioning screw hole 12, and the fixing plate 21 and the female mold 1 are fixed together with the bolt. The fixing direction of the socket aluminum part 3 in the channel 11 is determined by adjusting the direction of the positioning block 22 when it is inserted into the fixing plate 21.
[0042] In order to determine the insertion depth of the connecting ring 31 in the channel 11, a pad 23 is provided on the side of the fixing plate 21 near the female mold 1, and two pads 23 are respectively provided on the left and right sides of the positioning block 22.
[0043] Working principle: When printing the female mold 1, the mold closing baffle 42 is selected according to the position of the positioning screw hole 12. Then, the positioning pin 43 is made to pass through the mold closing baffle 42 and fit into the positioning groove 451. At this time, the female mold 1 material is covered on the surface of the male mold 41 of the machine body to obtain the female mold 1 with the positioning screw hole 12. Then, one side of the positioning block 22 is fitted into the socket aluminum part 3. According to the fixing direction of the socket aluminum part 3, the other side of the positioning block 22 is connected to the fixing plate 21. Then, the fixing plate 21 is connected to the female mold 1. Finally, the machine shell molding material is covered inside the female mold 1 to obtain the machine shell with the socket aluminum part 3. Finally, the plug 322 is connected to the connecting plate 321.
