Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. 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.
[0021] like Figure 1-4 As shown, a tailstock feeding device of a fully automatic window grinder includes a tailstock box 1, a taper shank sleeve 2 is installed in the tailstock box 1, and a rotary center 3 is inserted in the taper shank sleeve 2, so that the tailstock box 1 can be matched and docked with rotary centers 3 of different models, which is beneficial to improving the compatibility of the tailstock feeding device. The rotary center 3 includes a conical portion 301 and a cylindrical portion 302, the conical portion 301 is coaxially connected to the cylindrical portion 302, the diameter of one end of the conical portion 301 close to the cylindrical portion 302 is larger than the diameter of the other end away from the cylindrical portion 302, and the diameter of the end of the conical portion 301 close to the cylindrical portion 302 is smaller than the cross-sectional diameter of the cylindrical portion 302.
[0022] A front connecting plate 4 is installed at the end of the rotary center 3 away from the tailstock box 1, and a plurality of ring-shaped evenly distributed tightening columns 5 are installed on the side of the front connecting plate 4 away from the rotary center 3, so as to evenly distribute the tightening force on the workpiece and avoid deformation or damage of the workpiece caused by single-point force, which helps to improve the processing accuracy and workpiece quality. An annular protrusion 12 is coaxially connected to the side of the cylindrical portion 302 away from the conical portion 301, and an annular groove 13 is provided at the center of the side of the front connecting plate 4 away from the tightening column 5, and the annular protrusion 12 is consistent with the annular groove 13. In this embodiment, a plurality of through holes for bolts to penetrate are arranged at the bottom of the annular groove 13, and a threaded groove for bolts to be screwed in is provided on the annular protrusion 12, so as to facilitate the docking of the front connecting plate 4 with the rotary center 3.
[0023] An L-shaped cylinder connecting plate 6 is provided on one side of the tailstock box 1 away from the rotary center 3, and a double-axis thin cylinder 7 is installed on the side wall of the cylinder connecting plate 6 close to the top, and the double-axis thin cylinder 7 is used to drive the tailstock box 1 to move.
