[0019] 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.

[0020] Please see Figure 1-6 The present invention provides a technical solution: a jig for grinding civil aircraft parts, including a support frame 1, a clamping motor 2 fixedly connected to one side of the support frame 1, a rotating threaded column 3 fixedly connected to the output shaft of the clamping motor 2 through a coupling, a movable block 4 movably connected to the outer wall of the rotating threaded column 3, a limiting column 5 movably connected to one side of the movable block 4, and a connecting block 6 fixedly connected to the top of the movable block 4.

[0021] A clamping plate 7 is fixedly connected to the top of the connecting block 6, a side hinge 8 is fixedly connected to one side of the support frame 1, a protective frame 9 is fixedly connected to one side of the side hinge 8, a connecting bolt 10 is movably connected inside the support frame 1, and a lower hinge 16 is fixedly connected to the bottom of the support frame 1. This makes the jig for grinding civil aircraft parts more convenient to use, provides comprehensive protection for the jig when it is not in use, reduces environmental damage to the jig when it is not in use, extends the overall service life of the jig, reduces the frequency of subsequent jig maintenance, and reduces the operating costs of subsequent work.

[0022] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: an electric push rod 11 is fixedly connected inside the support frame 1, there are two support frames 1, and each support frame 1 is provided with two electric push rods 11 inside, which can adjust the overall working height of the fixture. The bottom end of the electric push rod 11 is fixedly connected to a base 12, and the bottom area of ​​the base 12 is larger than the bottom area of ​​the electric push rod 11, which improves the stability of the fixture during operation and is beneficial to the long-term use of the fixture.

[0023] A locking bolt 13 is movably connected to one side of the protective frame 9. A mounting plate 14 is movably connected to the outer wall of the locking bolt 13. A mounting handle 15 is fixedly connected to one side of the mounting plate 14, which facilitates locking the position of the two protective frames 9 when they are closed, and also facilitates moving the entire clamp when not in use.

[0024] One side of the movable block 4 is movably connected to the outer wall of the limiting column 5, and the length of the limiting column 5 is equal to the length of the rotating threaded column 3, which allows the movable block 4 to move in a stable straight line. The interior of the protective frame 9 is movably connected to one side of the support frame 1 through the side hinge 8, and the interior width of the protective frame 9 is equal to the width of the support frame 1, which allows the protective frame 9 to cover and protect the top of the support frame 1 and its connecting parts. The bottom of the support frame 1 is fixedly connected to one side of the lower hinge 16, and there are two lower hinges 16, which facilitates the stacking of the two support frames 1.

[0025] like Figure 1-5 As shown, when a user needs to use a jig for grinding civil aircraft parts, the electric push rod 11 extends, causing the base 12 to contact the ground. This allows the support frame 1 to reach an appropriate working height. The part to be clamped is placed at the connection center of the two support frames 1. The clamping motor 2 operates, and the output shaft of the clamping motor 2 rotates, causing the rotating threaded column 3 to rotate. The rotation of the rotating threaded column 3 causes the movable block 4 to move, thereby allowing the movable block 4 to drive the connecting small block 6 to move on the clamping plate 7. This allows the two clamping plates 7 to clamp the part, thus completing the subsequent grinding. When the electric push rod 11 is not used, it retracts, causing the base 12 to retract into the support frame 1. The protective frame 9 is rotated by the side hinge 8, allowing the protective frame 9 to cover the sides and top of the support frame 1. The connecting bolt 10 is rotated and removed. Then, the two protective frames 9 are stacked on top of each other by the lower hinge 16. The mounting plate 14 is locked to the two protective frames 9 by the locking bolt 13. Now, the entire jig can be moved to the appropriate position by the mounting handle 15.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
