[0013] Embodiment

[0014] As Figure 1 、 Figure 2 and Figure 3 shown, the rotating saw flat square tooling provided in this embodiment includes a fixed base plate 1 and a rotating base plate 3. A central positioning hole 2 is opened at the center of the surface of the fixed base plate 1, and a connecting protrusion that is rotationally matched with the central positioning hole 2 is formed at the center of the bottom of the rotating base plate 3. Through the cooperation of the connecting protrusion and the central positioning hole 2, the rotating base plate 3 can rotate on the surface of the fixed base plate 1; at the same time, two positioning pin holes 9 are correspondingly opened on the fixed base plate 1 and the rotating base plate 3, and the circular angular separation of the two positioning pin holes 9 is 180°. A positioning lock pin that matches the positioning pin hole 9 is also provided at the positioning pin hole 9; that is, through the positioning pin hole 9 on the fixed base plate 1 and the positioning pin hole 9 on the rotating base plate 3, it is possible to quickly confirm that the rotating base plate 3 rotates 180°, and after the rotation is completed, the positioning lock pin is inserted into the aligned positioning pin holes 9 of the fixed base plate 1 and the rotating base plate 3, thereby limiting the rotation of the rotating base plate 3 to prevent it from rotating;

[0015] Two fixed toolings 4 are symmetrically installed on the surface of the rotating base plate 3. In this embodiment, the two fixed toolings 4 and the two positioning pin holes 9 are distributed in a cross shape. A vertical workpiece positioning pin 10 is formed on one side of each fixed tooling 4, which is used to quickly position the workpiece when installing the workpiece and then complete the installation of the workpiece on the fixed tooling 4;

[0016] A locking screw 5 is vertically provided at the midpoint between the two fixed toolings 4. The bottom end of the locking screw 5 extends into the rotating base plate 3 and the fixed base plate 1 and is threadedly engaged with the rotating base plate 3 and the fixed base plate 1. A pressure strip 6 is threadedly connected to the upper part of the locking screw 5. Locking nuts 7 are provided at positions on the locking screw 5 close to the pressure strip 6 and close to the rotating base plate 3. The two ends of the bottom of the pressure strip 6 are respectively fixedly connected with pressure plates 8, and each pressure plate 8 corresponds to a fixed tooling 4; when the locking nut 7 is used to press the pressure strip 6, the pressure plate 8 presses the workpiece on the fixed tooling 4, and at this time, the locking nut 7 at the lower part of the screw presses the rotating base plate 3;

[0017] A spring is sleeved on the screw between the pressure strip 6 and the rotating base plate 3.

[0018] In use, two workpieces can be quickly installed on a fixed fixture 4 through workpiece positioning pins 10, that is, the present utility model can clamp four workpieces at a time through two fixed fixtures 4. After the workpieces are installed, rotate the pressure bar 6 by 90°, so that the pressing plates 8 at both ends of the pressure bar 6 correspond to the fixed fixture 4, and then lock the locking nut 7, so that the pressure bar 6 drives the pressing plates 8 to press the workpieces tightly. After pressing, operate the sawing machine to perform flat-square sawing on one side of the outer circle of the workpiece. After the processing is completed, loosen the locking nut 7, pull out the positioning lock pin, rotate the rotating bottom plate 3 by 180°, then insert the positioning lock pin again, and lock the locking nut 7. At this time, the workpiece has rotated 180°. Then operate the sawing machine again to perform flat-square sawing on the other side of the outer circle of the workpiece. After the processing is completed, loosen the locking nut 7, move the pressure bar 6 upward, and then rotate the pressure bar 6 by 90° to disassemble the workpiece from the fixed fixture 4.

[0019] The above are only the preferred embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modification and replacement based on the technical solution and the inventive concept provided by the present utility model should be covered within the protection scope of the present utility model.
