The turntable feeding mechanism can continuously transfer the thin-walled aviation aluminum alloy tubular castings to a processing position close to the mobile drilling mechanism, and the anti-deformation internal support mechanism can provide local support for the edge area of ​​the opening of the thin-walled aviation aluminum alloy tubular castings when the mobile drilling mechanism is drilling.

Under the action of the rubber pad 56, the problem of excessive support and deformation of the tubular casting is avoided, and the friction between the tubular casting and the round rods 55 is improved.

[0026] like Figure 1-Figure 3 As shown, the limiting structure 5 includes a disc 51, the outer wall of the disc 51 is rotatably connected to the middle of the right part of the bracket 1, four slide grooves 54 penetrating the disc 51 are opened on the left side of the disc 51, and a driving assembly 53 is fixedly installed on the left end of the right part of the bracket 1.

[0027] By setting the toothed disc 52, when the tubular casting needs to be rotated, the driving assembly 53 is started, and under the meshing action between the gear 67 and the toothed disc 52, the toothed disc 52 drives the disc 51 to rotate, and then drives the tubular casting to rotate, which can help find the drilling position.

[0028] like Figure 3 As shown, the inside of the four slide grooves 54 are all slidably connected with round rods 55, and the four slide grooves 54 all penetrate the left and right sides of the toothed disc 52.

The outer walls of the right parts of the four round rods 55 are respectively slidably connected to the inside of the four oblique slot holes 58. The front ends of the four round rods 55 extend out of the left end of the top of the bracket 1, and the outer walls of the left parts of the four round rods 55 are fixedly connected with rubber pads 56.

[0029] By providing the inclined slot hole 58, when the limit plate 57 rotates, under the action of the inclined slot hole 58, the four round rods 55 slide in the inclined slot hole 58 and slide outward in a diffused manner inside the slide groove 54. Under the action of the rubber pad 56, excessive support is avoided, which may lead to deformation of the tubular casting, and at the same time, the friction between the tubular casting and the round rods 55 is improved.

At the same time, the self-locking characteristics between the worm 512 and the worm wheel 513 can be used to maintain the stability of the limit plate 57 to a certain extent.

[0032] like Figure 4 As shown, the adjustment structure 6 includes a rectangular frame 61, the right part of the bottom end of the rectangular frame 61 is fixedly connected to the top end of the bracket 1, and the front and rear positions on the left and right sides of the rectangular frame 61 are fixedly connected with guide rods 63, the outer walls of the two guide rods 63 are slidably connected with slide plates 62, the top of the slide plate 62 is fixedly installed with the bottom end of the hydraulic rod 2, the outside of the right end parts of the two guide rods 63 are movably sleeved with springs 64, the right ends of the two springs 64 are fixedly connected to the right ends inside the rectangular frame 61, the left ends of the two springs 64 are fixedly connected to the right end of the slide plate 62, and the left end of the slide plate 62 is fixedly connected with a traction rope 65.

[0033] By setting the traction rope 65 and the spring 64, the traction rope 65 pulls the slide plate 62 to slide left, and then the opening position is adjusted to the left. When the opening position needs to be adjusted to the right, the traction rope 65 is released. At this time, under the reaction force of the spring 64, the slide plate 62 slides to the right, and then the opening position is adjusted to the right. The two cooperate with each other to make the position of the opening more accurate, thereby improving the practicability of the opening equipment.

[0034] like Figure 4 and Figure 5 As shown, a first cavity 66 is provided in the inner cavity at the top of the left side of the rectangular frame 61, and a gear 67 is rotatably connected in the middle of the bottom end of the first cavity 66.

Conversely, the electric telescopic rod 69 is driven to retract, and the traction rope 65 can be released.

[0036] The working principle of the utility model is as follows: when in use, one end of the thin-walled aviation aluminum alloy tubular casting is fitted to the left side of the top of the bracket 1, and all the round rods 55 and the rubber pads 56 are kept inside the tubular casting. Thereafter, the motor 510 is started, thereby driving the worm 512 to rotate, thereby driving the worm wheel 513 to rotate, and thereby driving the limit plate 57 to rotate. At this time, under the action of the inclined slot hole 58, the four round rods 55 slide in the inclined slot hole 58 while sliding outward in a diffused manner inside the slide groove 54, thereby making the four round rods 55 support the inner wall of the tubular casting outward. Under the action of the rubber pad 56, the problem of excessive support and deformation of the tubular casting is avoided, and at the same time, the friction between the tubular casting and the round rods 55 is increased. Thereafter, if it is necessary to rotate the tubular casting, the drive assembly 53 is started, and the meshing action between the gear 67 and the toothed disc 52 is Under the action of the drill bit 4, the tubular casting is drilled. When the left and right positions of the drilling holes need to be adjusted, the electric telescopic rod 69 is started. The electric telescopic rod 69 pushes the left rack 68 to slide, thereby driving the gear 67 to rotate, thereby driving the right rack 68 to slide. The two racks 68 slide, thereby driving the two slide bars 611 to slide in opposite directions, thereby causing the traction rope 65 to be staggered and stored in the second cavity 610. During this process, the traction rope 65 pulls the slide plate 62 to slide left, thereby adjusting the hole opening position to the left. When the hole opening position needs to be adjusted to the right, the traction rope 65 is released in the opposite steps. At this time, under the reaction force of the spring 64, the slide plate 62 slides to the right, thereby adjusting the hole opening position to the right.
