Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0040] Please see Figure 1-3 This utility model provides a test fixture for aircraft parts, comprising:
[0041] A first clamping mechanism is disposed on the support frame 1;
[0042] The first clamping mechanism includes: a power unit, a clamping unit, and a guide unit;
[0043] The power unit is connected to the top of the support frame via a base;
[0044] The movable part of the power unit is connected to one end of the clamping part, and the other end of the clamping part is connected to the guide part;
[0045] The guide portion is located on the opposite side of the power unit and is connected to the top of the support frame 1;
[0046] The second clamping mechanism is connected to the clamping part.
[0047] The power unit includes: a first lead screw 2, a slider 3, a mounting plate 4, and a connecting arm 5;
[0048] The mounting plate 4 is located between the base and the guide portion, and is connected to the top of the support frame 1. A gap is left between the mounting plate 4 and the base.
[0049] The first lead screw 2 passes through the base and is threadedly connected to the base. One end of the first lead screw 2 is provided with a handle, and the other end of the first lead screw 2 is rotatably connected to the mounting plate 4 through a bearing.
[0050] The slider 3 is sleeved on the first lead screw 2 and is threadedly connected to the first lead screw 2;
[0051] The other side of the slider 3 is connected to the clamping part via the connecting arm 5.
[0052] The first lead screw can be rotated by operating the handle, which in turn causes the slider to move on the first lead screw, thereby causing the clamping part to move.
[0053] The clamping part includes: a first clamping block 6 and a second clamping block 7;
[0054] The first clamping block 6 and the second clamping block 7 are arranged symmetrically.
[0055] One end of the first clamping block 6 and the second clamping block 7 are respectively hinged to the two sides of the slider 3 by the connecting arm 5 through pins;
[0056] The other ends of the first clamping block 6 and the second clamping block 7 are inserted into the guide portion;
[0057] The second clamping mechanism is connected to the side of both the clamping block and the second clamping block 7.
[0058] When the slider moves, it drives the connecting arm to move, which in turn drives the first clamping block and the second clamping block to move along the guide section, thereby adjusting the distance between the first clamping block and the second clamping block.
[0059] The guide section includes: a guide rod 8 and a support block 9;
[0060] Two support blocks 9 are provided and are arranged symmetrically. The support blocks 9 are connected to the top of the support frame 1.

[0062] The other ends of the first clamping block 6 and the second clamping block 7 are both sleeved on the guide rod 8;
[0063] The guide rod serves to guide the movement of the first clamping block and the second clamping block.
[0064] A second clamping mechanism is connected to the first clamping mechanism;
[0065] The first clamping mechanism is used to clamp parts in the horizontal direction. By operating the power component of the first clamping mechanism, parts of different sizes can be clamped.
[0066] The second clamping mechanism is used to clamp small-sized parts when the first clamping mechanism stops operating.
[0067] The second clamping mechanism includes: a second lead screw 10, a pressing block 11, and a limiting plate 12;
[0068] The first clamping block 6 and the second clamping block 7 are provided with through holes, and the pressing block 11 is sleeved in the through holes;
[0069] The limiting plate 12 has a U-shaped structure that is rotated 90° in the horizontal direction. The limiting plate 12 is connected to the outer side of the first clamping block 6 and the second clamping block 7 respectively. The limiting plate 12 is located on both sides of the through hole.
[0070] The second lead screw 10 passes through the limiting plate 12 and is rotatably connected to the extrusion block 11 on the same side.
[0071] When the first lead screw is operated, the distance between the first clamping block and the second clamping block can be adjusted according to the size of the component, so as to meet the testing of large-sized components. When replacing small-sized components, the distance between the first clamping block and the second clamping block is first adjusted by adjusting the first lead screw, and then the small-sized component is clamped by operating the second lead screw.
[0072] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
