[0027] The utility model is further described in detail below based on the accompanying drawings and implementation cases.

[0028] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively.

[0029] This embodiment provides a tail workpiece processing fixing tool, referring to Figure 1, including an installation platform 1 and a clamping mechanism arranged on the installation platform 1, the clamping mechanism supports and fixes the tail workpiece 5, the clamping mechanism includes a supporting table 2 arranged below the tail workpiece 5 to support it, a vertical clamping assembly 3 for pressing the upper end surface of the tail workpiece 5 to fix the tail workpiece 5, and a transverse clamping assembly 4 for pressing the side of the tail workpiece 5 to fix the tail workpiece 5, so that the lower surface of the tail workpiece 5 can fit tightly with the supporting table 2, the vertical clamping assembly 3 and the transverse clamping assembly 4 can clamp and fix the tail workpiece 5 from multiple directions, and even if the tail workpiece 5 is subjected to forces from multiple directions during processing, it can maintain a stable state.

[0030] In this embodiment, a positioning groove 21 which is recessed inward is provided on the supporting plate 2, and the contour of the outer surface of the positioning groove 21 matches the contour of the outer surface of the tail workpiece 5, so that the tail workpiece 5 can be accurately placed on the supporting plate 2. Specifically, the positioning groove 21 includes a supporting surface 211 and a limiting surface 212, the shape of the supporting surface 211 matches the shape of the lower surface of the tail workpiece 5 so that the supporting surface 211 fits with the lower surface of the tail workpiece 5, and the limiting surface 212 matches the shape of the side of the tail workpiece 5 away from the transverse clamping component 4 so that the limiting surface 212 fits with the side of the tail workpiece 5, the supporting surface 211 extends along the length direction of the tail workpiece 5, and the limiting surface 212 extends along the height direction of the tail workpiece 5, and the supporting plate 2 realizes stable support for the tail workpiece 5 through the positioning and matching of the positioning groove 21 and the tail workpiece 5.

[0031] The vertical clamping assembly 3 includes a first clamping member 31 and a first driving member 32 . The first driving member 32 can drive the first clamping member 31 to rotate so as to abut against the upper end surface of the tail wing workpiece 5 and provide a downward clamping force, so that the tail wing workpiece 5 can fit tightly with the supporting plate 2 .

[0032] Further, the first driving member 32 is set as a cylinder, the piston rod end of the cylinder is hinged to one end of the first clamping member 31, and a support column 33 is provided on the cylinder, one end of the support column 33 is hinged to the cylinder, and the other end is hinged to the middle of the first clamping member 31. Under the drive of the cylinder, the first clamping member 31 can rotate with the support column 33 as a fulcrum. When the cylinder piston rod moves upward, it drives the first clamping member 31 to rotate downward to clamp the tail workpiece 5. When the cylinder piston rod moves downward, it drives the first clamping member 31 to rotate upward to release the tail workpiece 5, that is, the cylinder can flexibly adjust the position of the first clamping member 31. The cylinder is controlled by an air valve. By adjusting the output pressure of the cylinder, the size of the clamping force of the first clamping member 31 on the tail workpiece 5 can be changed, so that the clamping force acting on workpieces with different qualities and processing requirements can be freely adjusted within a certain range, thereby meeting various processing requirements.

In this embodiment, the second driving member 42 can be a cylinder, a motor, or other component that can drive the second pressing member 41 to move and provide a clamping force.

[0034] Furthermore, the outer surface shape of the second clamping member 41 close to the tail workpiece 5 matches the side shape of the tail workpiece 5, that is, the contact area when the second clamping member 41 contacts the tail workpiece 5 is increased, which can reduce the risk of force damage to the tail workpiece 5 to a certain extent.

[0035] At the same time, since the vertical clamping assembly 3 and the horizontal clamping assembly 4 can provide clamping force to the tail wing workpiece 5 from multiple directions, when the processing position during the processing may overlap with the position of the clamp in a certain direction to form interference, the tail wing workpiece 5 can be clamped and fixed without replacing the clamp, which helps to improve processing efficiency.

[0036] A positioning column 6 is also provided on the mounting platform 1. The position of the positioning column 6 corresponds to the position of the connecting hole on the tail wing workpiece 5. The positioning cooperation between the positioning column 6 and the connecting hole makes it easier to install the tail wing workpiece 5 on the supporting plate 2, which is beneficial to improving the processing accuracy of the tail wing workpiece 5.

[0037] In this embodiment, the supporting plate 2 is detachably connected to the mounting platform 1 by a plurality of fixing bolts, and can adapt to tail wing workpieces 5 of different specifications by replacing supporting plates of different specifications, which helps to improve the applicability of the fixing tooling in the above scheme.

[0038] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
