[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 machining platform for machining aerospace structural parts, referring to... Figure 1 and Figure 2 The system includes a worktable 1. One end of the top wall of the worktable 1 is equipped with a clamping assembly 11 for holding the end of a part, and the other end has a first movable seat 121 that slides along the length of the worktable 1. The first movable seat 121 carries a machining assembly 12 for machining the part. Specifically, the clamping assembly 11 can be a three-jaw chuck, which can center and clamp the end of a shaft-like part. A motor is installed inside the worktable 1 to drive the three-jaw chuck to rotate. The machining assembly 12 includes a slide box and a cutting tool mounted on the slide box. The slide box is mounted on the first movable seat 121. A guide rod and a lead screw are arranged parallel to each other along the length of the worktable 1. The guide rod and the lead screw are slidably connected to the first movable seat 121 and threadedly connected to it, respectively. The worktable 1 also has a motor for driving the lead screw to rotate.

[0021] In this embodiment, a second movable seat 2 is slidably connected to the side wall of the worktable 1 along its length. The second movable seat 2 is provided on both side walls of the worktable 1, and a support frame is provided between the two second movable seats 2. The support frame is located between the clamping assembly 11 and the processing assembly 12. A support ring 3 for supporting the part is provided on the support frame. Specifically, the support ring 3 consists of a fixed petal 31 and a movable petal 32. The fixed petal 31 is fixed to the support frame, one end of the movable petal 32 is hinged to one end of the fixed petal 31, and the other end of the movable petal 32 is detachably connected to the fixed petal 31 via a connector. When the movable petal 32 and the fixed petal 31 are engaged, a receiving cavity is formed between the movable petal 32 and the fixed petal 31 to accommodate the end of the part. The support ring 3 then supports the part by locking the connector. Depending on the length of the part extending beyond the three-grip chuck, the position of the support ring 3 supporting the part can be adjusted by moving the second movable seat 2, improving the rotational stability of the part during processing.

[0022] Reference Figure 3 Specifically, the connector includes a connecting buckle 33, a first connecting rod 34 integrally fixed at the end of the fixed flap 31 away from the hinge axis, and a second connecting rod 35 integrally fixed at the end of the movable flap 32 away from the hinge axis. The first connecting rod 34 and the second connecting rod 35 are parallel to each other. A sliding connecting seat 36 is slidably disposed on the first connecting rod 34 along its own length direction. The connecting buckle 33 is fixedly installed on the connecting seat 36. The first connecting rod 34 is provided with at least one magnetic element 37 for magnetically adsorbing the connecting seat 36 along its own length direction. By sliding the connecting seat 36, the connecting buckle 33 can be slidably sleeved on the second connecting rod 35, thereby connecting and fixing the ends of the fixed petal 31 and the movable petal 32. When the connecting seat 36 is attracted and fixed by the magnetic component 37, the connecting buckle 33 remains sleeved on the second connecting rod 35. The magnetic attraction of the magnetic component 37 can ensure that the position of the connecting seat 36 is relatively stable during the work process, and can maintain support for the workpiece. Moreover, the operator can quickly slide the connecting seat 36 to disengage the connecting seat 36 from the magnetic component 37, so as to release the restriction on the end of the movable petal 32.

[0023] In this embodiment, two sets of support members are respectively provided on the fixed petal 31 and the movable petal 32. The support members include a threaded rod 41 and a support seat 42. A first gear 43 is rotatably mounted on both the fixed petal 31 and the movable petal 32. The threaded rod passes through the first gear 43. The support seat 42 is rotatably connected to the end of the threaded rod 41 that extends into the receiving cavity. A support wheel 44 for rolling contact with the outer wall of the part is rotatably mounted on the support seat 42. The support seat 42 is damped and slidably connected to the movable petal 32 and the fixed petal 31. A driving member is provided on one side of the support ring 3 for synchronously driving multiple first gears 43 to rotate. By driving multiple first gears 43 to rotate synchronously, each first gear 43 can cooperate with the threaded rod 41 to adjust the length of the threaded rod 41 extending into the receiving cavity, thereby enabling the support ring 3 to effectively support workpieces of different diameters.

[0024] Specifically, the driving component includes a connecting frame 51, which is axially slidably connected to one side of the fixed segment 31 along the hinge axis of the movable segment 32. Multiple second gears 52 corresponding to the first gear 43 are rotatably mounted on the connecting frame 51. Both the first gear 43 and the second gear 52 are bevel gears. By sliding the connecting frame 51, the first gear 43 and the second gear 52 can be meshed or separated in a one-to-one correspondence. A gear is coaxially fixedly connected to each second gear 52. A synchronous belt 53 is provided on the connecting frame 51, which is wound around and meshes with the gears coaxially connected to each second gear 52. A guide wheel or a guide plate can be rotatably mounted on the connecting frame 51 to guide the installation direction of the synchronous belt 53, forming a roughly "U" shape to facilitate component installation. Specifically, multiple guide rods 55 are fixedly installed on the side wall of the connecting frame 51. The guide rods 55 are all parallel to the sliding direction of the connecting frame 51. A guide hole 56 is provided on the fixed plate. The end of the guide rod 55 away from the connecting frame 51 passes through the guide hole 56 and is connected to an anti-detachment plate to prevent the guide rod 55 from detaching from the guide hole 56.

[0025] A handle 54 is connected to any one of the second gears 52. By rotating the handle 54, multiple second gears 52 can be driven to rotate synchronously, thereby adjusting the movement distance of multiple support seats 42 in the receiving cavity. The second movable seat 2 has a threaded hole, and a locking bolt is threaded into the threaded hole. By tightening the locking bolt, the locking bolt is tightly pressed against the side wall of the worktable 1, thereby restricting the sliding of the second movable seat 2 on the clamping assembly 11 and improving the stability of the support ring 3 when supporting parts.

[0026] Reference Figure 4 An elastic limiting element is provided on the fixed petal 31 to restrict the sliding of the guide rod 55 relative to the fixed petal 31. Specifically, the elastic limiting element includes a spring 57 and a limiting protrusion 58. A mounting groove is provided on the inner wall of the guide hole 56. Both the spring 57 and the limiting protrusion 58 are disposed in the mounting groove. The limiting protrusion 58 is slidably installed in the mounting groove and can extend out of the mounting groove. The spring 57 is used to drive the limiting protrusion 58 to slide out of the mounting groove opening, so that part of the limiting protrusion 58 extends out of the mounting groove. The part of the limiting protrusion 58 extending out of the mounting groove is spherical. A limiting groove 59 is provided on the guide rod 55. When the limiting groove 59 slides with the guide rod 55 and aligns with the mounting groove in the guide hole 56, under the elastic force of the spring 57, the limiting protrusion 58 is pushed to cooperate with the limiting groove 59, thereby restricting the sliding of the connecting frame 51 and maintaining the meshing state of the first gear 43 and the second gear 52.
