Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology, and in particular to a turntable tooling for machining aerospace parts. Background Technology

[0002] Aviation parts mainly refer to various spare parts of aircraft, including aircraft fuselage parts, aircraft engine parts, instruments, airborne equipment, hydraulic systems and accessories. When processing aviation parts, especially large parts, a turntable fixture is generally required. The clamping and rotation of the turntable fixture can greatly facilitate the processing of aviation parts.

[0003] Patent CN221495740U discloses a turntable fixture for machining aerospace parts, including a turntable with a cross groove at the top and a fixed block at the center of the cross groove. Rotating screws are provided on the four side walls of the fixed block, and a rotating motor is provided on the side of the rotating screws that are not connected to the fixed block. Movable fitting mechanisms are movably sleeved on the outer walls of the four rotating screws. By rotating the screws, each movable fitting mechanism is driven to move to fit against the side wall of the part, so as to achieve the purpose of clamping and limiting the part.

[0004] However, for large and heavy aerospace parts, relying solely on clamping friction from the outer wall of the part for clamping is not stable enough. Furthermore, many aerospace parts have complex surface structures, and the available positions for limiting and fixing vary. Therefore, a turntable fixture with a wider range of applications is needed. Utility Model Content

[0005] In view of the above problems, this utility model provides a turntable fixture for machining aerospace parts.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A turntable fixture for machining aerospace parts is provided, including a first fixture base and a second fixture base. The first fixture base and the second fixture base are rotatably connected. A first limiting member is provided on the first fixture base to restrict the rotation of the first fixture base. A plurality of mounting seats are rotatably arranged at intervals along the circumference of the first fixture base. A second limiting member is provided on the first fixture base to restrict the sliding of the mounting seats. A first mounting rod is vertically raised and lowered on the mounting seat. A third limiting member is provided on the first mounting rod to adjust the relative position between the first mounting rod and the mounting seat. A second mounting rod is rotatably connected to the top end of the first mounting rod. The second mounting rod is horizontally adjustable in length. An abutment part for abutting against the outer wall of the part is provided at the end of the second mounting rod away from the first mounting rod.

[0007] Furthermore, a groove is provided on the side wall of the tooling base along its circumference, and the mounting seat is slidably connected in the groove. The second limiting member includes a first screw rod, which passes radially through the tooling base and is threadedly connected to the mounting seat. One end of the first screw rod near the first tooling base is connected to a brake pad for frictional contact with the outer wall of the first tooling base, and the other end of the first screw rod is fixedly provided with a first handle.

[0008] Furthermore, the first mounting rod is vertically slidably connected to the mounting base, and the third limiting member includes a second screw rod, which is vertically and rotatably connected to the mounting base. The top end of the second screw rod passes vertically through the top end of the first mounting rod and is threadedly connected to the first mounting rod. A second handle is fixedly connected to the top end of the second screw rod.

[0009] Furthermore, the first limiting member includes an adjusting gear ring and an adjusting gear. The adjusting gear ring is coaxially fixed on the side of the first tooling base near the second tooling base. The adjusting gear is rotatably mounted on the second tooling base and meshes with the adjusting gear ring. The second tooling base is provided with a driving member for driving the adjusting gear to rotate.

[0010] Furthermore, the driving component includes an adjusting screw, which includes a guide portion and a screw portion. The guide portion and the screw portion are coaxially and fixedly connected. The screw portion is threadedly connected to the second tooling base radially. The guide portion is coaxially and slidably inserted in the adjusting gear. One end of the guide portion away from the screw portion extends out of the second tooling base and is coaxially provided with a hexagonal adjusting groove.

[0011] Furthermore, the abutment part includes a connecting collar, and a connecting rod with a square cross-section is fixedly connected to the side wall of the second mounting rod away from the first mounting rod. The connecting collar has a mounting hole adapted to the connecting rod. A first connecting head and a second connecting head are fixedly provided at intervals along the circumference of the outer wall of the connecting collar. The first connecting head is used to abut against the outer wall of the part, and the outer wall of the second connecting head is designed as a conical surface. The second connecting head is used to coaxially abut against the hole on the part. A limit screw is coaxially fixedly connected to the end of the connecting rod away from the second mounting rod. A limit nut for limiting the connecting collar from dislodging from the connecting rod is threaded onto the limit screw.

[0012] Furthermore, the second mounting rod includes a fixed rod and a movable rod. The fixed rod is connected to the first mounting rod, and the movable rod is slidably sleeved on the fixed rod. A strip groove is formed on the outer wall of the movable rod along its own length direction. Connecting ear plates are fixedly provided on both sides of the strip groove. After the fastening bolt passes through the two ear plates at the same time, it is threadedly connected to the fastening nut so that the movable rod clamps the fixed rod.

[0013] The beneficial effects of this utility model are as follows: When clamping and fixing aerospace parts, the parts are placed on the first tooling base. The mounting seats around the first tooling base are moved, the first mounting rod is rotated, and the length of the second mounting rod is adjusted so that the abutting part is aligned with the abutting platform on the part that can be pressed down or the hole that can be centered. Then, by fixing the position of the mounting seat, the mounting rod is lowered so that the abutting part presses down on the part, or the length of the second mounting rod is fixed to keep the abutting part centered with the hole of the part, thus completing the centering and fixing effect of the part. By adjusting the first limiting member, the first tooling base can be rotated relative to the second tooling base, so that the processing equipment can process the parts from different angles, making it suitable for clamping and fixing more aerospace parts.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This application discloses a turntable fixture for machining aerospace parts, referring to... Figure 1 and Figure 2The fixture includes a first tooling base 1 and a second tooling base 2. Both the first tooling base 1 and the second tooling base 2 have circular horizontal cross-sections. The first tooling base 1 is coaxially rotatably connected above the second tooling base 2. The first tooling base 1 is provided with a first limiting member to restrict its rotation relative to the second tooling base 2. In this embodiment, the first limiting member specifically includes an adjusting gear ring 12 and an adjusting gear 21. The adjusting gear ring 12 is coaxially fixedly connected to the base of the first tooling base 1. The adjusting gear 21 is rotatably mounted on the second tooling base 2 and meshes with the adjusting gear ring 12. A driving member is provided on the second tooling base 2 to drive the adjusting gear 21 to rotate.

[0021] Specifically, the driving component can be an adjusting screw 22, which includes a guide portion 221 and a screw portion 222. The guide portion 221 and the screw portion 222 are coaxially connected. The adjusting screw 22 is radially disposed within the second tooling base 2. The screw portion 222 of the adjusting screw 22 is threadedly connected within the second tooling base 2. The guide portion 221 of the adjusting screw 22 has a polygonal cross-section. A guide hole adapted to the guide portion 221 of the adjusting screw 22 is coaxially passed through the adjusting gear 21. By rotating the adjusting screw 22, the adjusting screw 22 can be threadedly connected to the second tooling base 2, and at the same time, the adjusting screw 22 can move relative to the adjusting gear 21 and drive the adjusting gear 21 to rotate in the forward / reverse direction. This drives the first tooling base 1 to rotate relative to the second tooling base 2 and effectively prevents the first tooling base 1 from rotating on its own under other external forces.

[0022] Reference Figure 3 A mounting base 3 is slidably connected to the first tooling base 1 along its circumference. The mounting base 3 is provided with a second limiting member to restrict its sliding relative to the first tooling base 1. Specifically, a groove 11 is formed along the circumference of the outer wall of the first tooling base 1, and the mounting base 3 is slidably connected within the groove 11. At least three mounting bases 3 are provided along the circumference of the first tooling base 1. The second limiting member includes a first screw 31. A first threaded sleeve is fixed to the mounting base 3. The first screw 31 passes through the first threaded sleeve and is threadedly connected to it. A brake pad 33 is connected to the end of the first screw 31 near the first tooling base 1. The brake pad 33 is rotatably connected to the first screw 31 and is designed to conform to the curved surface of the outer wall of the first tooling base 1, increasing the contact area and friction when the brake pad 33 contacts the first tooling base 1. A first handle 32 is connected to the end of the first screw 31 away from the first tooling base 1, allowing the operator to operate and rotate the first screw 31.

[0023] A first mounting rod 30 is vertically and slidably mounted on the mounting base 3. The first mounting rod 30 is provided with a third limiting member to restrict its sliding. Specifically, the third limiting member can be a second screw 301, which is vertically and rotatably connected to the mounting base 3. A second threaded sleeve is fixedly connected to the top end of the first mounting rod 30, and the second screw 301 passes through and is threadedly connected to the second threaded sleeve. A second handle 302 is fixedly connected to the top end of the second screw 301, and the second screw 301 is rotated by operating the second handle 302.

[0024] Reference Figure 4 A second mounting rod 4 is rotatably connected to the top of the first mounting rod 30. The length of the second mounting rod 4 is adjustable, and the end of the second mounting rod 4 away from the first mounting rod 30 is provided with an abutment part 5 for abutting against the outer wall of the part. By moving the mounting seat 3 to a position on the part with an abutment platform, the movement of the mounting seat 3 is restricted. Then, the length of the second mounting rod 4 is adjusted so that the abutment part 5 is aligned with the platform on the outer wall of the part that needs to be abutted. Then, the first mounting rod 30 is lowered so that the abutment part 5 abuts against and clamps the workpiece. By pressing down on the part with multiple abutment parts 5 at the same time, the part is limited and fixed.

[0025] In this embodiment, the abutment portion 5 includes a connecting collar 51. A first connecting head 53 and a second connecting head 54 are spaced circumferentially on the outer wall of the connecting collar 51. At least one of the first connecting head 53 and the second connecting head 54 has a conical outer wall, and the interval angle between the first connecting head 53 and the second connecting head 54 is not less than 90°. A connecting rod 52 is horizontally fixedly connected to the side wall of the second mounting rod 4. In this embodiment, the interval angle between the first connecting head 53 and the second connecting head 54 is 90°, the outer wall of the second connecting head 54 is designed as a conical surface, the cross-section of the connecting rod 52 is square, and a mounting hole adapted to the connecting rod 52 is coaxially provided on the connecting collar 51, allowing the connecting collar 51 to be detached from the connecting rod 52 and its mounting angle adjusted. In other embodiments, the mounting rod can also be octagonal or other shapes, allowing the connecting collar 51 to rotate and adjust to the same angle as the interval angle between the first connecting head 53 and the second connecting head 54.

[0026] A limiting screw 55 is coaxially connected to the end of the connecting rod 52 away from the second mounting rod 4. A limiting nut 56 is threaded onto the limiting screw 55. After the connecting collar 51 is installed, the limiting nut 56 is installed to prevent the connecting collar 51 from dislodging from the connecting rod 52. By adjusting the installation angle of the connecting collar 51, the first connecting head 53 can be vertically downward to press and fix the part, or the second connecting head 54 can be horizontally facing the part so that the second connecting head 54 can coaxially abut against the hole on the part. By pressing the part downward from multiple directions or positioning the hole on the part with the second connecting head 54, various aerospace parts on the turntable can be effectively limited and fixed.

[0027] In order to determine the position of the second connector 54 with the hole on the part, in this embodiment of the application, the second mounting rod 4 includes a fixed rod 41 and a movable rod 42. The fixed rod 41 is connected to the first mounting rod 30, and the movable rod 42 is slidably sleeved on the fixed rod 41. A strip groove 43 is formed on the outer wall of the movable rod 42 along its own length direction. Connecting ear plates are fixedly provided on both sides of the strip groove 43. After the fastening bolt 44 passes through the two ear plates at the same time, it is threadedly connected to the fastening nut so that the movable rod 42 clamps the fixed rod 41.
