Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary assembly tooling for aircraft accessories, in particular to a tight-fitting assembly tooling for propeller blade root accessories. Background Art

[0002] During the assembly process of composite propeller blades, components such as the support ring (cage support and tapered roller bearing outer ring assembly) and the Glyd ring must be assembled onto the blade root. This ensures a tight fit between the support ring (cage support and tapered roller bearing outer ring assembly) and the Glyd ring. However, during actual assembly, the Glyd ring often shears due to limited operating space.

[0003] Therefore, how to design an auxiliary assembly tool for propeller root accessories that can avoid Gley ring shearing is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0004] The utility model provides a tight-fit assembly tool for propeller root accessories, which solves the technical problem that shearing phenomenon often occurs in the Glyd ring during the tight-fit assembly of the Glyd ring and the support ring (cage support and tapered roller bearing outer ring assembly).

[0005] The utility model solves the above technical problems with the following technical solutions: a propeller root accessory is tightly fitted with an assembly tool, which is used to compress the support ring and the grid ring that are spaced apart on the propeller root, comprising: a support plate, a plurality of support rods, a guide cylinder and a compression screw.

[0006] A screw hole is provided in the middle of the support plate; the multiple support rods are arranged in a direction perpendicular to the support plate and one end of each support rod is detachably connected to the support plate at intervals along the edge direction of the support plate, and the other ends of the multiple support rods are bent toward the center direction of the support plate to form a clamping hook; the guide tube is placed between the multiple support rods along the length direction of the support rod and the end thereof close to the support plate is a closed end; the paddle root is passed through the guide tube; the support ring can contact with the other end of the guide tube; the grid ring can contact with multiple clamping hooks; the clamping screw is screwed into the screw hole and its screw-in end is fixed on the closed end of the guide tube, so as to rotate the clamping screw, reduce the distance between the guide tube and the multiple clamping hooks and compress the support ring and the grid ring.

[0007] The beneficial effect of the present invention is that it replaces the manual tight-fitting assembly method of the support ring and the grid ring, and utilizes the blade root to be passed through the guide tube. Since the end of the guide tube away from the support plate is in contact with the support ring, and multiple clamping hooks are in contact with the grid ring, the distance between the guide tube and the multiple clamping hooks can be shortened during the rotation of the clamping screw, and the support ring and the grid ring can be clamped to avoid shearing of the grid ring, thereby improving the tightness of the tight fit between the support ring and the grid ring.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the support plate includes a connecting plate and a plurality of connecting strips, the screw hole is arranged in the middle of the connecting plate; the plurality of connecting strips are arranged parallel to the connecting plate and one end thereof is fixed on the connecting plate at intervals along the edge direction of the connecting plate; the plurality of support rods are arranged perpendicular to the plurality of connecting strips and one end thereof is detachably connected to the other end of the plurality of connecting strips.

[0010] A further beneficial effect of adopting the above method is: by utilizing multiple connecting strips to be detachably connected to multiple support rods, the overall volume of the connecting plates can be reduced, the weight of the propeller root accessory auxiliary assembly tooling can be greatly reduced, and its practicality can be improved.

[0011] Furthermore, it also includes a handle, which is fixed to the protruding end of the tightening screw extending out of the screw hole. BRIEF DESCRIPTION OF THE DRAWINGS
