DETAILED DESCRIPTION

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments (for ease of description and understanding, hereinafter referred to as...). Figure 2 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Please see Figures 1-3 This utility model provides a technical solution: a positioning fixture for a large disc-shaped forging, including a base 1, a positioning platform 3, a positioning mechanism 4 and a clamping mechanism;

[0025] Base 1 is used to support the entire tooling;

[0026] Positioning platform 3 is located at the upper end of base 1 and is used to place large disc-shaped forgings;

[0027] The positioning mechanism 4 includes a first adjusting screw 41, a groove 42, and a slider 43. The groove 42 is radially disposed on the base 1, and the slider 43 is slidably connected in the groove 42. One end of the first adjusting screw 41 is rotatably connected to the slider 43, and the other end of the first adjusting screw 41 passes through the base 1 and is threadedly connected to the base 1. By rotating the first adjusting screw 41, the slider 43 is controlled to move radially in the groove 42, and the positioning position is adjusted according to the disc-shaped forgings of different diameters.

[0028] The clamping mechanism 6 includes a C-shaped frame 61, a pressure plate 62, and a second adjusting screw 63. The C-shaped frame 61 is connected to the slider 43 via a connecting rod 5. The open end of the C-shaped frame 61 faces the positioning table 3. The pressure plate 62 is located inside the C-shaped frame 61. One end of the second adjusting screw 63 is rotatably connected to the pressure plate 62, and the other end of the second adjusting screw 63 passes through the upper end of the C-shaped frame 61 and is threadedly connected to the C-shaped frame 61. By rotating the second adjusting screw 63, the pressure plate 62 can be moved up and down, which can clamp and fix disc-shaped forgings of different thicknesses.

[0029] Furthermore, in order to improve the positioning stability of the large disc-shaped forging, there are six grooves 42, which are evenly distributed along the central axis of the base 1.

[0030] Furthermore, to facilitate the clamping of the large disc-shaped forging, the lower surface of the open end of the C-shaped frame 61 is at the same height as the upper surface of the positioning table 3.

[0031] To avoid scratching the circumferential surface of the disc-shaped forging, a rubber pad is provided on the inner side of the C-shaped frame 61.

[0032] To increase the stability of the base 1 supporting the positioning platform 3, the base 1 and the positioning platform 3 are connected by a column 2, and reinforcing ribs 9 are evenly distributed between the column 2 and the lower end face of the positioning platform 3.

[0033] To ensure the levelness of the base 1, multiple support legs 8 are provided at the lower end of the base 1.

[0034] To prevent the disc-shaped forging from sliding during the positioning process, the upper surface of the positioning table 3 is provided with anti-slip texture 7.

[0035] In use: The large disc-shaped forging is placed in the middle position of the positioning platform 3 by the lifting mechanism. Then, according to the diameter of the disc-shaped forging, the slider 43 is moved in the radial direction of the base 1 by rotating the first adjusting screw 41 until the inner side of the C-shaped frame 61 contacts the outer circle of the disc-shaped forging. At this time, the lower end face of the disc-shaped forging is in contact with the lower surface of the open end of the C-shaped frame 61. Then, the second adjusting screw 63 is rotated to control the movement of the pressure plate 62 to press the upper end face of the disc-shaped forging, thus completing the positioning of the disc-shaped forging.

[0036] This invention can position large disc-shaped forgings of different diameters. At the same time, according to the thickness of the disc-shaped forging, the second adjusting screw 63 is rotated to make the pressure plate 62 press on the surface of the disc-shaped forging, thus completing the positioning of the disc-shaped forging and greatly improving the convenience of use.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
