[0015] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figures 1-2As shown, a positioning tray for powder metallurgy sintering includes a tray body 1 with several mounting holes 2 distributed along the transverse and longitudinal directions on the upper surface of the tray body 1. Each mounting hole 2 has a through annular groove 3 on its outer side. The tray body also includes a positioning component, comprising a shaft 4 inserted into the mounting holes 2. A wing plate 5 is integrally formed on the upper end of the shaft 4. A positioning disc 6, for abutting against the outer circumferential surface of a part, is connected to the free end of the wing plate 5. A locking bolt 7 passes through the wing plate 5, and a locking nut is screwed onto the free end of the locking bolt 7, which passes through the annular groove 3. The end face of the locking nut abuts against the lower surface of the tray body 1. A threaded shaft 8 is provided on the upper surface of the free end of the wing plate 5, and the positioning disc 6 is screwed onto the threaded shaft 8. The threaded shaft 8 allows the positioning disc 6 to be detachably connected to the wing plate 5, facilitating the replacement of positioning discs 6 of different specifications to suit different part blanks. The positioning disc 6 is circular and available in various diameter specifications. The lower surface of the wing plate 5 is fitted to the upper surface of the pallet body 1. L-shaped handles 9 are provided on both sides of the pallet body 1, and the free end of the horizontal section of the handle 9 is welded to the side of the pallet body 1.

[0017] During operation, the operator places the part blank on the tray body 1, then selects several suitable mounting holes 2, aligns the shaft 4 in the positioning component with the corresponding mounting holes 2, and installs it. After completion, the axis of the mounting hole 2 is used as the axis of rotation, causing the wing plate 5 to rotate. At the same time, the positioning disk 6 of the required specifications is screwed onto the threaded shaft 8 at the free end of the wing plate 5. When the positioning disk 6 comes into contact with the part blank during the rotation of the wing plate 5, the locking nut is screwed onto the free end of the locking bolt 7 that passes through the wing plate 5 and the annular groove 3. This fixes the rotation angle between the wing plate 5 and the upper surface of the tray body 1 by friction locking. Through several positioning components, the part blank can be stably fixed on the tray body 1, preventing the blank in the tray body 1 from shifting, thereby improving the quality of the sintered product.
