[0002] The propeller hub centerpiece is a critical component in aircraft and possesses a complex, special-shaped design. Three eccentric propeller shafts are distributed across the hub. Previously, the hub's profile was machined using five-axis machining, which resulted in lengthy machining times, significant tool wear, and excessively high costs. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a turning processing device for hub parts with simple structure, short processing time and high efficiency.

[0004] The technical solution of the utility model for solving the above technical problems is: a hub-type parts turning processing device, including a base, the base is composed of a vertical plate and a bottom plate; a limit block is provided at the right end of the bottom plate, the limit block is fixed to the bottom plate by a first screw, a positioning groove is provided on the left side of the upper limit block of the bottom plate, the wedge clamping assembly is placed in the positioning groove, and a through hole is vertically opened on the left side of the wedge clamping assembly on the bottom plate; a through hole is horizontally opened in the middle of the vertical plate, a counterweight block is provided on the upper part of the vertical plate, and a flange is installed on the left side of the vertical plate.

[0005] Furthermore, the counterweight is fixed to the upper portion of the vertical plate with bolts.

[0006] Furthermore, the left side of the vertical plate is processed into a bevel.

[0007] Furthermore, the bottom plate and the vertical plate are positioned by two cylindrical pins.

[0008] The technical effect of the utility model is that: the propeller hub parts turning processing device provided by the utility model tightens the nut at the wedge clamping assembly, so that the wedge clamping assembly expands and contacts and presses the step positioning edge of the bottom surface of the propeller hub center piece, thereby ensuring that the propeller shaft part is concentric with the lathe spindle, and the propeller shaft part will not have the problem of uneven angle distribution caused by movement and eccentricity, and the cutting efficiency is greatly improved, and the product quality is guaranteed.

[0012] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0013] See also Figure 1-3 The present invention includes a base 1, a first screw 2, a stopper 3, a wedge clamping assembly 4, a second screw 5, a positioning shaft 6, a washer 7, a first nut 8, a screw 9, a second nut 10, a counterweight 11, a flange 12, a cylindrical pin 13, and a third screw 14. The base 1 consists of two parts: a bottom plate 101 and a vertical plate 102. The propeller shaft of the hub centerpiece is eccentric and angled, so one side of the vertical plate 102 is machined into an inclined surface to ensure that the propeller shaft can be concentric with the lathe spindle. The bottom plate 101 and the vertical plate 102 are positioned by screws 9 to ensure the correct positioning and dimensions. The vertical plate 102 and the bottom plate 101 are connected by screws 9 and second nuts 10.

[0014] A limit block 3 is provided at the right end of the base plate 101, and the limit block 3 is fixed to the base plate by a first screw 2. A positioning groove is provided on the left side of the upper limit block 3 of the base plate, and the wedge clamping assembly 4 is placed in the positioning groove. A through hole is vertically opened on the left side of the wedge clamping assembly 4 on the base plate 101; a through hole is horizontally opened in the middle of the vertical plate 102, and a counterweight block 11 is provided on the upper part of the vertical plate 102, and the counterweight block 11 is fixed to the upper part of the vertical plate 102 by a screw 9 and a second nut 10. A flange 12 is installed on the left side of the vertical plate 102, and the flange 12 is assembled on the lathe spindle to cooperate with it. The inner hole at the inclined surface of the base 1 is matched with the circular boss of the flange 12 to connect so that the inclined surface of the base 1 fits the surface of the flange 12.

[0015] The inner hole of the hub center piece is matched with the positioning shaft 6 and positioned on the base 1, and the wedge clamping assembly 4 is connected to the positioning groove of the base 1. The wedge clamping assembly 4 is in the initial state.

[0016] Position the propeller shaft of the hub centerpiece by aligning the locating edge and centering it. Tighten nut I8 at the top of the hub centerpiece to tighten it. Connect screw 9 to the two threaded holes at the top of base 1. Install counterweight 11 through screw 9 and tighten nut II10 to secure it. Tighten nut 5 at wedge clamp assembly 4, expanding it to contact and tighten it against the stepped locating edge on the bottom of the hub centerpiece. This ensures the shaft is concentric with the lathe spindle and prevents the shaft from shifting or eccentrically shifting, which can cause uneven angle distribution.

[0017] After completing the processing of one propeller shaft, loosen the second nut 10, take out the counterweight 11, loosen the first nut 8 and the second screw 5, take out the workpiece, and then perform the same operation on the other two propeller shafts.
