[0008] Both end surfaces of the C-shaped frame are inwardly installed with single-fork ear connection structures, which are used to connect with a set of double-fork ear structures of the central wing, thereby positioning and fixing the central wing;

[0009] Multiple sets of adjustable support structures are set on the C-shaped frame. When multiple sets are used simultaneously, they can also clamp the central wing, thereby further strengthening the fixation of the central wing.

[0010] A set of adjustable support structures includes an upper adjustable support structure and a lower adjustable support structure, both of which have the same structure; the adjustable support structure includes a fixed support, a rocker arm, a clamping screw, and a movable clamping block;

[0011] The rocker arm is installed on the C-shaped frame through a fixed support. One end of the rocker arm cooperates with the clamping screw, and the bottom end of the clamping screw is connected to the movable clamping block. The movable clamping block can rotate around the bottom end of the clamping screw and tilt at a small angle.

[0012] The auxiliary device also includes: a lateral support structure;

[0013] The lateral support structure includes a sleeve bracket, a compression screw, and a movable pressure plate;

[0014] The sleeve bracket is fixed to the outer wall of the C-shaped frame, and the pressing screw passes through the central threaded hole of the sleeve bracket and out of the inner wall of the C-shaped frame to be connected with the movable pressing plate;

[0015] The movable pressing plate can rotate around the exit end of the pressing screw and tilt at a small angle.

[0016] The turning mechanism is provided with a dividing plate for multi-angle turning and real-time fixation of the positioning frame.

[0017] Four sets of adjustable supports are provided at the bottom of the support frame for the stable placement of the device.

[0018] Beneficial effects:

[0019] This auxiliary device has a simple structure and is easy to operate, effectively supporting and securing the center fin of the horizontal tail. The device can be tilted at a fixed angle, providing multiple angles for reaming butt joints. This provides the appropriate operating angle for reaming bolt holes in different locations, improving reaming efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The utility model designs an auxiliary device for reaming holes in the butt joint of the central wing of the horizontal tail of a helicopter. The device can not only fix the central wing of the horizontal tail, but also realize multi-angle flipping and fixing, thereby providing a suitable operating angle for the reaming operation and improving the efficiency of the reaming operation.

[0026] The utility model provides an auxiliary device for reaming holes in the center wing butt joint of a helicopter horizontal tail. Figure 1 As shown, the main structural components of the device include a positioning frame and a supporting frame.

[0027] Positioning frame Figure 2 and Figure 3 As shown, it is used to position, support and secure the center wing of the horizontal tail.

[0028] The positioning frame is provided with a set of single-fork ear connection structures for connecting with a set of double-fork ear structures of the central wing, thereby positioning and fixing the central wing.

[0029] The positioning frame is equipped with multiple sets of adjustable support structures. When multiple sets are used simultaneously, they can also clamp the central wing, thereby further strengthening the fixation of the central wing.

[0030] Both ends of the positioning frame are provided with a turning mechanism, and a dividing plate is provided on the turning mechanism for multi-angle turning and real-time fixation of the positioning frame.

[0031] Support frame such as Figure 4 As shown, it is used to support the positioning frame and is fixedly connected to the flip mechanisms at both ends of the positioning frame.

[0032] The bottom of the support frame is provided with 4 sets of adjustable supports for the stable placement of the device.

[0033] The utility model is used as an example Figure 5 As shown, during use, the center fin of the horizontal stabilizer is placed on the device's positioning frame. Positioned using the forked lugs at each end, the fin is tightened using the positioning bolts and nuts. Multiple sets of adjustable supports on the positioning frame act simultaneously to further clamp the fin. Based on the location of the bolt holes to be reamed, the positioning frame is flipped to the appropriate angle and secured, and the reaming operation begins. After all bolt holes have been reamed, the center fin is removed, completing the device's use.
