The integrated automatic drilling and deburring processing equipment according to claim 7, characterized in that: The guide groove group includes a plurality of guide grooves (42) arranged in sequence and at intervals along the circumference of the rotating cylinder (32), and each guide groove (42) extends in an arc along the axial direction of the rotating cylinder (32); The pushing member includes a plurality of push rods (43) arranged corresponding to the plurality of guide grooves (42), and a lifting plate (44) connected to the centers of the plurality of push rods (43). The grinding rod (51) is vertically and slidably arranged in the center of the lifting plate (44). The outer ends of the plurality of push rods (43) are respectively connected to the corresponding guide grooves (42).

9. The integrated automatic drilling and deburring processing equipment according to claim 7, characterized in that: The rotary grinding mechanism (5) further includes a motor (52) installed in the installation cavity, a rotating shaft (53) connected to the output end of the motor (52), a rotating drum (54) fixed axially to the rotating shaft (53), and a limiting slider (55) axially slidably installed in the rotating drum (54); The lower end of the grinding rod (51) extends axially into the rotating drum (54) and is fixedly connected to the limiting slider (55). The limiting slider (55) is used to rotate when the motor (52) drives the rotating shaft (53) to drive the rotating drum (54) to rotate, thereby driving the grinding rod (51) to rotate.

10. The integrated automatic drilling and deburring processing equipment according to claim 9, characterized in that: A plurality of guide grooves (42) are provided on the inner wall surface of the lower end of the rotating drum (54) and are circumferentially spaced and inwardly concave, and each guide groove (42) extends along the axial direction of the rotating drum (54); A plurality of guide strips are correspondingly provided on the outer wall surface of the limit slider (55), and each guide strip is slidably embedded in the corresponding guide groove (42), so that the limit slider (55) and the rotating drum (54) are connected into one piece through the cooperation of the guide strip and the guide groove (42), and the limit slider (55) can also slide axially relative to the rotating drum (54).
