The phrase appears in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment to other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] The utility model embodiment provides a kind of machining center positioning device, as Figures 1-5 As shown in the figure, the machining center positioning device comprises: a box body 1, a rotating column 2 is rotatably installed on the box body 1, a plurality of clamping grooves are formed in the rotating column 2;Shell 3 is fixedly installed on the rotating column 2, two strip-shaped holes are formed in the top of the shell 3;Speed reducer motor 4 is fixedly installed on the inner wall of the bottom of the box body 1, the output shaft of the speed reducer motor 4 is fixedly connected with the bottom end of the rotating column 2;Positioning mechanism is assembled on the shell 3 for fixing workpiece;Two fixing mechanisms are installed on the box body 1 for fixing rotating column 2.

[0023] In the embodiment, when the positioning device is in use, first, the workpiece to be processed is placed on the top of the shell 3, and then the positioning mechanism is started to fix the workpiece. Since the plurality of positioning rods 9 on the positioning mechanism can freely stretch and retract under the elastic action of the plurality of springs 10, this feature enables the positioning device to flexibly adapt to workpieces of various shapes, thereby significantly improving its versatility. Once the workpiece is firmly fixed, the stability of the workpiece during processing can be ensured, which is crucial to ensure the processing accuracy. Next, if angle adjustment of the positioned workpiece is needed, the operator only needs to start the speed reducer motor 4, which will drive the rotating column 2 to rotate, and the rotation of the rotating column 2 will in turn drive the shell 3 and the workpiece on the shell 3 to rotate together. In this way, the position of the workpiece can be easily adjusted to the appropriate processing angle, providing great convenience for the operator. After the angle adjustment is completed, in order to prevent the workpiece from rotating accidentally during processing, the two fixing mechanisms can be used to lock the rotating column 2, ensuring that the rotating column 2 remains stationary during processing of the workpiece.

The two sliding blocks 6 will drive the two box bodies 8 to move closer to each other through the two limiting blocks 7, causing the plurality of rubber blocks 12 to press the workpiece. After the plurality of rubber blocks 12 come into contact with the workpiece, the plurality of positioning rods 9 will slide on the two box bodies 8 respectively and press the plurality of springs 10 respectively. When the plurality of positioning rods 9 cannot continue to slide on the two box bodies 8, the positioning of the workpiece is completed. This positioning method can be used for workpieces of various shapes, thereby significantly improving its versatility. When a rubber block 12 needs to be replaced due to severe wear, the operator only needs to rotate the rubber block 12 to make the bolt 11 connected with it disengage from the positioning rod 9, and then install a new rubber block 12 on the positioning rod 9 in the same way, making the replacement more convenient.

[0028] The two inner walls of the strip-shaped hole are fixedly installed with limiting rod 16 in the further preferred embodiment of the utility model, and the two limiting rods 16 are respectively connected with the two limiting blocks 7 in a sliding mode.

[0029] In the embodiment, the stability of the two limiting blocks 7 during horizontal movement can be improved by using the two limiting rods 16, when the two sliding blocks 6 drive the two limiting blocks 7 to approach each other or move away from each other, the two limiting blocks 7 will slide horizontally on the two limiting rods 16 respectively.

[0030] The two ends of the bidirectional screw 5 are fixedly installed with rotating disc 17 in the further preferred embodiment of the utility model, and the two rotating discs 17 are rotatably installed with handle.

[0031] In the embodiment, the two rotating discs 17 and the two handles can be used to facilitate the operator to rotate the bidirectional screw 5 more easily.
