[0029] See also Figure 1-8 The present invention provides a technical solution for an adjustable fixture for machining aviation parts, comprising a chassis 1, a reference Figure 1 The chassis 1 is the basic frame of the fixture, carrying all the following components. The four sides of the chassis 1 are equipped with lifting components 2 through sliding components 4. Under the sliding effect of the sliding component 4, all components of the single group can be pushed and displaced, and the position can be adjusted according to the shape of the parts. The pushing component 4 includes a pushing cylinder 43 and a beam 41. The pushing cylinder 43 is the power source for sliding. The lifting component 2 includes a bracket 27, which is installed on the beam 41. As the beam 41 moves, the lateral position is adjusted. The bracket 27 is installed on the beam 41. The bracket 27 The outer wall of the bracket 27 is covered with a sliding frame 22, which slides up and down on the outer wall of the bracket 27 and has adjusted its longitudinal position. The sliding frame 22 slides on the outer wall of the bracket 27. A pushing component 3 is installed on the top of the sliding frame 22. The pushing component 3 plays a role in clamping the parts, wherein the ejector frame 33 is pushed and contacts the parts for clamping. The pushing component 3 includes an ejector frame 33. A switching component 5 is installed at the end of the ejector frame 33. The switching component 5 can switch between flat and curved surfaces for clamping. After the ejector frame 33 moves, it drives the switching component 5 to clamp the aviation parts.

[0030] Combine Figures 1 to 4 As shown, after the push cylinder 43 in the pushing component 4 pushes the crossbeam 41 to move, it drives the lifting component 2 to adjust the lateral position, and the sliding frame 22 slides on the outer wall of the bracket 27 to adjust the effect of adjusting the longitudinal position of the part. After the ejector frame 33 rotates, the plane and the curved surface of the switching component 5 are adjusted, and then the switching component 5 is driven to contact and clamp the aviation part. With the cooperation of the above components, the longitudinal position and the longitudinal position can be adjusted according to the shape of the aviation part for clamping and fixing.

[0031] like Figure 2As shown, the sliding assembly 4 includes a slide 44 and two pushing cylinders 43. The push of the two pushing flagpoles 43 makes the pushing process more stable and is used to push the crossbeam 41 to move. The slide 44 is opened on the base frame 1, and the pushing cylinder 43 is installed on the base frame 1. The output end of the pushing cylinder 43 is installed with a crossbeam 41. The crossbeam 41 is used to be installed on the bracket 27. Rollers 42 are respectively installed at both ends of the crossbeam 41. After the crossbeam 41 moves, the rollers 42 are driven to slide inside the slide 44 to keep the movement of the crossbeam 41 stable, and reduce wear by rolling instead of friction. The rollers 42 are located inside the slide 44.

[0032] According to the shape of the aviation parts, each group of push cylinders 43 extends to push the crossbeam 41 to move, driving the roller 42 to roll inside the slide groove 44, so that the movement of the sliding assembly 4 is stable, and the lateral position of the bracket 27 is adjusted, and the movement is stable.

[0033] exist Figure 2 and Figure 3 In the figure, the lifting component 2 includes a bracket 27, which is the base of the lifting component 2. The bracket 27 is installed on the crossbeam 41, and a first servo motor 21 is installed at the bottom of the bracket 27. The first servo motor 21 is the power source for the lifting action of the lifting component 2. The outer wall of the bracket 27 is covered with a sliding frame 22. The sliding frame 22 is lifted and lowered after sliding on the outer wall of the bracket 27. A dispensing rod 26 is installed on the surface of the sliding frame 22. The outer wall of the dispensing rod 26 is covered with one end of the second push rod 25. The outer wall of the output end of the first servo motor 21 is provided with one end of the first push rod 23 through a ring 24. The other end of the first push rod 23 is movably connected to the other end of the second push rod 25. After the first push rod 23 and the second push rod 25 rotate, the sliding frame 22 is pushed.

[0034] The bracket 27 is the basic part of the lifting assembly 2. When the first servo motor 21 rotates, it drives the first push rod 23 to rotate. After the first push rod 23 rotates, it pushes the second push rod 25 to move. The two first rotate due to the movement space, and the second push rod 25 pushes the expenditure rod 26 to drive the slide frame 22 to slide on the outer wall of the bracket 27 to achieve the adjustment of the longitudinal position.

[0035] In order to clamp the aviation parts, a push assembly 3 is used for clamping, such as Figure 2 As shown, the pushing assembly 3 includes a vertical rod 31, which is the main body of the pushing assembly 3. The vertical rod 31 is installed on the upper surface of the sliding frame 22. The upper and lower parts of the outer wall of the vertical rod 31 are respectively provided with a lifting frame 33 and one end of the dispensing beam 32. The lifting frame 33 is eccentrically installed on the outer wall of the vertical rod 31, and clamps the aviation parts after rotation. The other end of the dispensing beam 32 is movably installed with an electric telescopic rod 34. After the electric telescopic rod 34 is extended, it pushes the lifting frame 33 to rotate, and the output end of the electric telescopic rod 34 is movably connected to the lifting frame 33.

[0036] After the electric telescopic rod 34 is extended, it pushes the ejector frame 33 to rotate on the outer wall of the vertical rod 31. The eccentric rotation of the ejector frame 33 clamps and fixes the aviation parts.

[0037] In order to adapt to the surface characteristics of different aviation parts, a switching assembly 5 is used. The switching assembly 5 includes a flat clamp 51 and a curved clamp 52. The flat clamp 51 and the curved clamp 52 are self-contained and are movably connected to the ejector frame 33 through a connecting shaft 53.

[0038] The flat clamping block 51 and the curved clamping block 52 rotate under the effect of the connecting shaft 53, switch according to the surface characteristics of the aviation part, and are fixed by the friction between the shafts.

[0039] In order to prevent the sliding frame 22 from sliding excessively, a clamping plate 7 is used for restriction. Clamping plates 7 are installed at both ends of the bottom of the bracket 27, and the clamping plates 7 clamp the bottom of the sliding frame 22 for limiting the position.

[0040] In order to make the switching component 5 rotate and switch, the toggle component 8 is used. The connecting shaft in the switching component 5 is controlled by the toggle component 8. The rotating component 8 includes a motor bracket 81 and a disbursement plate 85. The disbursement plate 85 is installed on the outer wall of the connecting shaft 53. The motor bracket 81 is installed on the upper surface of the ejector frame 33. A second servo motor 82 is installed inside the motor bracket 81. A transmission plate 83 is installed on the outer wall of the output end of the second servo motor 82. One end of a transmission rod 84 is installed at the end of the transmission plate 83. The other end of the transmission rod 84 is connected to the disbursement plate 85.

[0041] Under the effect of the rotation of the output end of the second servo motor 82, the transmission plate 83 and the transmission rod 84 are driven to rotate, the transmission rod 84 pushes the disbursement plate 85 to rotate, and the rotation of the disbursement plate 85 drives the connecting shaft 53 to rotate, thereby driving the flat clamping block 51 and the curved clamping block 52 to switch.

[0042] In some embodiments, the base frames 1 are movably connected via multiple groups of connection components 9 . The connection components 9 include a connection frame 91 and a connection plate 92 . The connection plate 92 is movably connected to the connection frame 91 via a rotating shaft 93 .

[0043] The movable connection and splicing between the connection frame 91 and the connection plate 92 complete the dynamic connection between the various base frames 1 to meet the requirements of the base frames 1 being able to be distributed in various forms.

[0044] In some embodiments, the rotating shaft 93 is limited and fixed by a fixing component 10, and the fixing component 10 includes a mounting tube 101 and a mounting frame 102. The mounting tube 101 is installed on the upper surface of the rotating shaft 93, and a clamping frame 103 is installed on the upper surface of the mounting tube 101. One end of the mounting frame 102 is installed on the upper surface of the connecting frame 91, and a connecting rod 105 is inserted into the other end of the mounting frame 102. One end of the connecting rod 105 is fixed with a clamping frame 104, and the clamping frame 104 is clamped on the outer wall of the clamping frame 103. The other end of the connecting rod 105 is installed with a screw 107, and the outer wall where the screw 107 and the mounting frame 102 intersect is threadedly installed with a screw ring 106.

[0045] After arranging the distribution of the base frame 1 according to the shape of the parts, it is necessary to fix the state of the connecting component 9. The connecting rod 105 is lowered to drive the card frame 104 to be sleeved on the outer wall of the card frame 103. Under the limitation of the screw ring 106 on the screw 107, the state of the connecting rod 105 is fixed, thereby fixing the rotating shaft 93. The state between the connecting plate 92 and the connecting frame 91 is fixed and cannot move.

[0046] In some embodiments, a flange 11 is installed on the side wall of the base frame 1. The flange 11 is a structure that connects the base frame 1 to the machining center.

[0047] The following is an explanation of the beneficial effects of the present invention with a preferred embodiment: according to the shape of the aviation parts, the position of the chassis 1 is arranged, the movable connection and splicing between the connecting frame 91 and the connecting plate 92 complete the dynamic connection between each chassis 1, so that the chassis 1 can be distributed in various forms. The connecting rod 105 is lowered to drive the card frame 104 to be sleeved on the outer wall of the card frame 103. Under the limit of the screw ring 106 on the screw 107, the state of the connecting rod 105 is fixed, thereby fixing the rotating shaft 93, and the state between the connecting plate 92 and the connecting frame 91 is fixed. After the push cylinder 43 of each group is extended, it pushes the crossbeam 41 to move, driving the roller 42 to roll inside the slide groove 44, so that the movement of the sliding component 4 is stable, and the lateral position of the bracket 27 is also made stable. The position is adjusted. When the first servo motor 21 rotates, it drives the first push rod 23 to rotate. After the first push rod 23 rotates, it pushes the second push rod 25 to move. The two first rotate due to the movement space, and the second push rod 25 pushes the expenditure rod 26 to drive the slide frame 22 to slide on the outer wall of the bracket 27. The first servo motor 21 can descend after rotating in the opposite direction. After the electric telescopic rod 34 is extended, it pushes the ejector frame 33 to rotate on the outer wall of the vertical rod 31. The eccentric rotation of the ejector frame 33 clamps and fixes the aviation parts. Under the effect of the rotation of the output end of the second servo motor 82, the transmission plate 83 and the transmission rod 84 are driven to rotate. The transmission rod 84 drives the expenditure plate 85 to rotate. The rotation of the expenditure plate 85 drives the connecting shaft 53 to rotate, thereby driving the switching of the flat clamp 51 and the curved clamp 52.
