Description

Technical Field

[0001] This utility model relates to the field of drilling and tapping center machine tool technology, and in particular to an intelligent manufacturing automatic vertical drilling and tapping center machine tool device. Background Technology

[0002] In the field of modern machining, vertical drilling and tapping centers are widely used for drilling, tapping, and other machining processes on various parts. However, during long-term machining, a large amount of iron filings, debris, and cutting fluid impurities will remain in the machining area. If these impurities are not cleaned in time, they will not only affect the accuracy of subsequent machining but may also cause wear on machine tool components and shorten the service life of the machine tool.

[0003] Currently, cleaning of most vertical drilling and tapping center machine tools relies mainly on manual operation, which is not only inefficient but also leaves cleaning blind spots, making it difficult to thoroughly remove impurities. Some machine tools with automatic cleaning functions have complex and costly cleaning devices, and the position adjustment of these devices is not flexible enough to accurately cover all areas requiring cleaning. Furthermore, existing cleaning devices often operate independently in terms of height, angle, and lateral position adjustments, lacking coordination and failing to quickly adapt to different cleaning needs. After cleaning, the cleaning devices cannot be effectively stored away, potentially affecting subsequent machining operations. Therefore, developing an automatic vertical drilling and tapping center machine tool device with a reasonable and simple structure, low production cost, easy installation, and flexible cleaning position adjustment is of significant practical importance.

[0032] like Figure 8 As shown, the specific structure of the longitudinal moving mechanism 71 includes a second motor 711 and a second screw 712; the second motor 711 is fixedly connected to the outside of the guide slot seat 4, and the second motor 711 is a servo motor or a stepper motor; the second screw 712 is movably connected to the inside of the guide slot seat 4, and the center of one side of the second screw 712 is fixedly connected to the output shaft of the second motor 711, and the second screw 712 is connected to the threaded hole provided in the center of the slider 5.

[0033] like Figure 9 As shown, the specific structure of the swing mechanism 72 includes a motor 721, a drive gear 722, a splined shaft 723, and a fixed half gear 724. The motor 721 is fixedly connected to the outside of the guide slot seat 4, and the motor 721 is a servo motor or a stepper motor.

[0034] The utility model is used as follows: It features a reasonable and simple structure, low production cost, and convenient installation. When cleaning is required after processing using an automatic vertical drilling and tapping center machine tool, motor 711 (belonging to the longitudinal movement mechanism 71) is started. Its output shaft drives screw 712 to rotate. Since screw 712 is connected to the threaded hole in the center of slider 5, under the action of threaded transmission, slider 5 will move longitudinally along guide groove seat 4, thereby adjusting the longitudinal working position of flushing head 2. If the lateral working position of flushing head 2 needs to be adjusted, motor 721 (belonging to the swing mechanism 72) is started first. The output shaft of motor 721 drives spline shaft 723 to rotate, which in turn drives drive gear 722 to rotate. Drive gear 722 meshes with fixed half gear 724, causing telescopic parallel linkage mechanism 3 to swing around the connection point with slider 5 through gear transmission, thereby achieving the lateral position of flushing head 2. If it is necessary to ensure that flushing head 2 is at the required height during swing, motor 611 (which belongs to synchronous drive device 61, and synchronous drive device 61 is part of telescopic drive mechanism 6) is started. Motor 611 drives drive pulley 612 to rotate, and drive pulley 612 drives driven pulley 616 to rotate through synchronous belt 614. This causes drive shaft 613 and drive shaft 615 to rotate synchronously. Drive shaft 613 drives spline shaft 62 and drive shaft 615 drives spline shaft 63 to rotate. Spline shaft 62 and spline shaft 63 are respectively connected to the spline hole in the center of end face gear 326, driving end face gear 326 to rotate. End face gear 326 meshes with drive gear 325. The rotation of drive gear 325 in turn drives screw 324 to rotate. Since the threaded hole in the center of telescopic arm 321 is connected to screw 324, the rotation of screw 324 will cause telescopic arm 321 to extend and retract within guide hole 323. The rinsing head 2 extends and retracts synchronously with the telescopic linkage 34 to adjust its height. After adjusting the position, angle, and height of the rinsing head 2, the external control system controls the rinsing head 2 to spray cleaning fluid to rinse and clean the processing area of ​​the machine tool body 1. During the cleaning process, the position, angle, and height of the rinsing head 2 can be adjusted again through the displacement drive mechanism 7 and the telescopic drive mechanism 6 according to the actual situation to ensure that the cleaning work is completed comprehensively and efficiently. Finally, after the cleaning work is completed, the rinsing head 2 is moved to one side inside the machine tool body 1 through the displacement drive mechanism 7 and the telescopic drive mechanism 6, so as not to affect the processing operation of the vertical drilling and tapping center machine tool.
