[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1 to 7 This utility model provides a technical solution: a multi-axis machining device for aerospace turbine parts, comprising: a machining machine tool 1;

[0028] It also includes: a shifting mechanism 2, which is mounted on the machine tool 1 and is used to move the machining position along the Y-axis;

[0029] The adjustment mechanism 3 is mounted on the shifting mechanism 2. The adjustment mechanism 3 works in conjunction with the shifting mechanism 2 to adjust the machining positions of the X-axis and Z-axis.

[0030] Angle adjustment mechanism 4 is located below the position adjustment mechanism 3. Angle adjustment mechanism 4 is used to adjust the processing orientation and angle position.

[0031] By setting up the shifting mechanism 2 and the adjusting mechanism 3, the machining head 48 can be adapted and adjusted in the X, Y, and Z axes according to the position of the aero-engine turbine components, thus facilitating the use of the machining work. By setting up the angle adjusting mechanism 4, the machining head 48 can be adjusted to the required orientation and angle position according to the various machining positions of the aero-engine turbine components, as well as for more difficult machining positions. This, in conjunction with the shifting mechanism 2 and the adjusting mechanism 3, enhances the flexibility of the machining head 48, ensures the machining effect, and provides convenience for the operators.

[0032] The shifting mechanism 2 includes limiting grooves 21 on both sides of the processing machine tool 1. A gantry frame 22 is slidably connected to the inner wall of each limiting groove 21. A first motor 23 is installed inside the gantry frame 22. A first gear 24 is fixedly connected to the output end of the first motor 23. A first rack 25 is fixedly connected to the bottom of the inner wall of the limiting groove 21. The first gear 24 and the first rack 25 are meshed together.

[0033] In use, the parts are fixed by the fixing components set on the top of the processing machine tool 1. Then, the Y-axis position is adjusted according to the position of the parts. By controlling the first motor 23 to run and rotate, the first motor 23 rotates the first gear 24. The rotating first gear 24 can move along the first rack 25, which allows the gantry 22 to slide in the limiting groove 21. Accordion cloths are set on both sides of the gantry 22. The side of the accordion cloth away from the gantry 22 is fixedly connected to the processing machine tool 1. In this way, the accordion cloths can prevent dust from entering the limiting groove 21 when the gantry 22 moves.

[0034] The adjustment mechanism 3 includes a frame plate 31 fixedly connected to the two gantry frames 22. A second motor 32 is fixedly connected to the inner side of the frame plate 31. A first reciprocating screw 33 is fixedly connected to the output end of the second motor 32. A shifting table 34 is threadedly connected to the outer side of the first reciprocating screw 33. The shifting table 34 is slidably connected to the frame plate 31.

[0035] When in use, when it is necessary to adjust the position of the X-axis of the processing head 48, the second motor 32 is controlled to rotate the first reciprocating screw 33. The rotating first reciprocating screw 33 drives the shift table 34 to move. When the shift table 34 moves, it can slide and guide within the frame plate 31.

[0036] A cylinder 35 is fixedly connected to the bottom of the shifting stage 34, and limit telescopic rods 36 are fixedly connected to the bottom of the shifting stage 34 and on both sides of the cylinder 35.

[0037] When it is necessary to adjust the Z-axis spatial position of the machining head 48 during use, the control cylinder 35 adjusts the height position of the machining head 48, and the stability of the fixed plate 41 can be enhanced by the limit telescopic rod 36.

[0038] Example 2

[0039] like Figures 3 to 7 In this second embodiment, the other structures remain unchanged, but the difference from the first embodiment is:

[0040] The angle adjustment mechanism 4 includes a fixed plate 41 fixedly connected to the telescopic end of the cylinder 35. The top of the fixed plate 41 is fixedly connected to the telescopic extension of the limiting telescopic rod 36. A fixed platform 42 is fixedly connected to the inner side of the fixed plate 41. A third motor 43 is fixedly connected inside the fixed platform 42. A second gear 44 is fixedly connected to the output end of the third motor 43. An internal gear ring plate 45 is meshed with the outer side of the second gear 44.

[0041] When in use, when it is necessary to adjust the position of the processing head 48, the third motor 43 is controlled to rotate the second gear 44, so that the rotating second gear 44 drives the internal gear ring plate 45 to rotate. When the internal gear ring plate 45 moves, it can rotate within the fixed plate 41 to a limited position, thereby adjusting the processing head 48 to the required position.

[0042] A first ball 46 is fixedly connected to the bottom of the fixed table 42, an adjustment plate 47 is provided on the outer side of the first ball 46, and a processing head 48 is fixedly connected to the bottom of the adjustment plate 47.

[0043] In use, by setting the angle adjustment plate 47 on the outside of the first ball 46, it is easy to adjust the angle adjustment plate 47 to multiple angles and to limit the angle adjustment plate 47.

[0044] Two electric telescopic rods 49 are fixedly connected to the bottom of the internal gear ring plate 45. The output ends of the two electric telescopic rods 49 are fixedly connected to a first ball shell 410. A double-headed ball rod 411 is provided inside the first ball shell 410. A second ball shell 412 is provided on the outside of the double-headed ball rod 411. The bottom of the second ball shell 412 is fixedly connected to the top of the angle adjustment plate 47. Two springs 413 are fixedly connected between the internal gear ring plate 45 and the angle adjustment plate 47.

[0045] In use, when it is necessary to adjust the angle of the processing head 48, the two electric telescopic rods 49 are controlled to work together. By controlling the extension or retraction of the telescopic ends of the electric telescopic rods 49, the first spherical shell 410 can be driven. A double-headed ball rod 411 is set between the first spherical shell 410 and the second spherical shell 412. The balls set at both ends of the double-headed ball rod 411 can cooperate with the first spherical shell 410 and the second spherical shell 412 to complete the limiting. Thus, when the telescopic ends of the electric telescopic rods 49 extend or retract, the processing head 48 can be adjusted to the required angle, and the spring 413 can provide a guiding and stabilizing effect on the position of the angle adjustment plate 47.
