They have a variety of functions and can perform a variety of machining operations such as drilling, milling, turning, and grinding.

[0003] At present, horizontal machining centers generate a large amount of metal chips when machining workpieces. These metal chips usually leave the tooling fixture under the action of oil spraying from an oil nozzle or air jetting from an air nozzle, but some metal chips inevitably remain on the tooling fixture, causing crushing of the workpiece when clamping a new workpiece, resulting in low product yield.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 The utility model provides a technical solution: a high-precision workpiece positioning device for a horizontal machining center, comprising a rotary cylinder 1, a support table 2, a positioning member 3, a positioning mechanism 4, a spray cleaning mechanism 5 and a high-frequency vibrator 6, wherein the support table 2 is mounted on the rotary cylinder 1, the positioning member 3 is mounted on the support table 2, a positioning groove 7 penetrating the positioning member 3 is provided on the positioning member 3, the positioning mechanism 4 is arranged in the support table 2 and extends into the positioning groove 7, the spray cleaning mechanism 5 is mounted on the positioning member 3, and the spray cleaning mechanism 5 is aligned with the positioning groove 7, and the high-frequency vibrator 6 is mounted on the positioning member 3;

[0024] The positioning mechanism 4 includes a telescopic cylinder 41 and a flat plate 42. The telescopic cylinder 41 is fixedly installed in the support platform 2. The flat plate 42 is installed on the telescopic end of the telescopic cylinder 41, and the flat plate 42 extends into the positioning groove 7. The telescopic cylinder 41 is extended and retracted to drive the flat plate 42 to slide, so as to facilitate the rapid flat pressing and positioning of the workpiece in the positioning groove 7.

[0025] The positioning member 3 is provided with a guide groove 8, and the flat plate 42 is slidably connected in the guide groove 8 to ensure that the flat plate 42 slides smoothly;

[0026] A limiting groove 9 is provided on the inner wall of the positioning groove 7 to facilitate the positioning of the workpiece;

[0028] Working principle: First, the workpiece is inserted into the positioning groove 7, and the telescopic cylinder 41 is extended to push the flat plate 42 to slide in the guide groove 8. The flat plate 42 presses the workpiece so that the workpiece is inserted into the limit groove 9, and then the workpiece is quickly positioned. Secondly, the horizontal machining center processes the workpiece. During processing, the oil nozzle 53 sprays coolant to cool the workpiece and the tool head, and the air nozzle 52 sprays high-pressure gas to blow away the metal chips generated during processing. Some of the metal chips will accumulate at the corners in the positioning groove 7. Then, After the work is completed, the high-frequency vibrator 6 vibrates to make the metal chips located at the corner of the positioning member 3 separate from the positioning member 3, and the rotating cylinder 1 rotates to make the positioning groove 7 in a vertical state. Under the action of multiple oil nozzles 53 and multiple air nozzles 52, the metal chips in the positioning groove 7 quickly separate from the positioning member 3, completing the thorough cleaning of the metal chips in the positioning member 3. Finally, the telescopic cylinder 41 retracts to pull the flat pressure plate 42 to slide in the guide groove 8, pushing the processed workpiece out of the limit groove 9, and then taking the processed workpiece out of the positioning groove 7.
