Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology, and in particular to a positioning and support tooling for fairing production. Background Technology

[0002] A fairing is a structure or outer surface with aerodynamic rectification function, widely used in aerospace, automotive, and aircraft industries. In aerospace, it primarily protects satellites and other payloads from harmful aerodynamic effects; while in other fields, it mainly reduces drag and improves performance. Depending on the part of the fairing, various composite structures are employed, such as epoxy composite skins reinforced with carbon fiber and fiberglass, and aluminum honeycomb sandwich adhesive-bonded structures. Therefore, in practical applications, additional machining is usually required after the fairing is prefabricated.

[0003] Due to the complex shape and structure of the fairing, it is difficult to meet the requirements for positioning and clearance during the manufacturing process, necessitating multiple re-clamping and repositioning operations. Furthermore, it is impossible to guarantee the stability of the fairing during manufacturing, easily causing scratches on the outer wall of the fairing. Therefore, there is an urgent need to design a positioning and support fixture for fairing production to solve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a positioning support fixture for fairing production, which can provide multi-point support for the fairing through several supports, and can fully clear the outer processing position of the fairing to facilitate subsequent processing.

[0005] To achieve the above objectives, this utility model provides the following solution:

A telescopic member is hinged between the middle of the support rod and one side of the mounting bracket. A positioning rod is fixedly connected between one end of the two support rods, and the positioning rod is detachably connected to one end face of the fairing.

[0010] Preferably, the mounting frame includes a U-shaped frame, with both ends of the frame fixedly connected to the top surface of the support frame, one side of the frame hinged to the telescopic member, and several reinforcing beams fixedly connected between the inner cavity sidewall of the frame and the top surface of the mounting frame.

[0023] It should be noted that, in order to make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Depend on Figure 1-4 The fairing 19 shown is used for positioning and supporting tooling, including a support frame. Mounting brackets are fixedly installed at both ends of the top surface of the support frame. Several arc-shaped mounting plates 2 are fixedly connected between the two mounting brackets. Several support members are detachably connected to the side of the mounting plate 2. The support members are used to provide abutment support to the outer side of the fairing 19. A positioning component is rotatably connected to one side of the two mounting brackets. A positioning plate 1 is fixedly installed on the mounting plate 2 away from the positioning component. The positioning plate 1 is set to abut against one end face of the fairing 19.

[0025] Further optimization of the design: The support includes a fixed block 3, with a rotating shaft 4 fixedly connected to one side of the fixed block 3. One end of the rotating shaft 4 passes through the mounting plate 2 and is rotatably connected to the mounting plate 2. A nut 5 is screwed onto one end of the rotating shaft 4. A push rod 6 passes through and is screwed onto the top and bottom surfaces of the fixed block 3, respectively. A top ball 7 is fixedly connected to one end of the push rod 6, and the top ball 7 abuts against the outer surface of the fairing 19. A handwheel 8 is fixedly connected to the other end of the push rod 6. The top ball 7 can make point contact with the outer surface of the fairing 19, avoiding the interference and poor accuracy problems caused by traditional line contact or surface contact in complex surface positioning support. At the same time, the push rod 6 can be adjusted up and down by rotating the handwheel 8, which is beneficial for adjusting the spacing of the fairing 19 and completing the support of the fairing 19.

[0026] To further optimize the design, a scale 9 is also provided between the fixing block 3 and the mounting plate 2, and the scale 9 is fixedly connected to the mounting plate 2; a pointer 10 is fixedly connected to the side of the fixing block 3, and the pointer 10 is aligned with the scale line of the scale 9. The pointer 10 can deflect as the fixing block 3 deflects, and thus can coincide with any scale line on the edge of the scale 9 to indicate the deflection angle, thereby providing normal support for the top ball 7 and improving the support effect of the fairing 19.

[0027] Further optimization of the design includes a positioning component comprising two support rods 11, each rotatably connected to one of two mounting brackets. A telescopic member 12 is hinged between the middle of each support rod 11 and one side of the mounting bracket. A positioning rod 13 is fixedly connected between one end of each of the two support rods 11. The positioning rod 13 is detachably connected to one end face of the fairing 19. Furthermore, the telescopic member 12 can be an electric cylinder, hydraulic cylinder, or pneumatic cylinder, capable of moving other components connected to it via a piston rod; this is existing technology and will not be elaborated further. The telescopic member 12 pushes the support rods 11 to rotate around one end of the mounting bracket, pushing the positioning rod 13 closer to the end face of the fairing 19 to abut against it, thus bringing the fairing 19 into the positioning groove 18 of the positioning plate 1, preventing the fairing 19 from shifting during processing.

[0028] Further optimization of the design: the mounting frame includes a U-shaped frame 14, with both ends of the frame 14 fixedly connected to the top surface of the support frame, one side of the frame 14 hinged to the telescopic member 12, and several reinforcing beams 15 fixedly connected between the inner cavity side wall of the frame 14 and the top surface of the mounting frame. By setting the mounting frame to a hollow structure, it is convenient to process the exterior of the fairing 19.

[0029] A further optimized design includes a support frame comprising a base plate 16 and several casters 17, with the casters 17 fixedly installed at one corner of the bottom surface of the base plate 16. The top surface of the base plate 16 is fixedly connected to the frame 14, and the casters 17 facilitate the movement or transportation of this invention. Furthermore, the casters 17 are self-locking, which facilitates the fixing during the processing of this invention.

[0030] Further optimization of the scheme: the positioning plate 1 has an L-shaped structure, and a positioning groove 18 is provided on one side of the positioning plate 1. The positioning groove 18 is adapted to and abuts against the side wall of the fairing 19. The L-shaped positioning plate 1 is used to lock one end of the side wall of the fairing 19 to prevent the fairing 19 from moving.

[0031] The working process of this embodiment is as follows:

[0032] First, insert one side wall of the fairing 19 into the positioning groove 18 of the positioning plate 1. Then, manually turn the handwheel 8 to drive the push rod 6 to rotate spirally within the fixing block 3, driving the top ball 7 to abut against the outer side wall of the fairing 19 until all the contact points of the top balls 7 on each mounting plate 2 with the outer side of the fairing 19 are on the same circumference. This allows the fairing 19 to be supported in the preset position, and the support is stabilized by the supports on several mounting plates 2.

[0033] Activate the telescopic component 12, drive the support rod 11 to lift up, the support rod 11 drives the positioning rod 13 to tilt up until it contacts one end face of the fairing 19, pushes the fairing 19 into the positioning groove 18, and fixes the fairing 19 laterally.

[0034] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
