The invention relates to a constant linear velocity gantry vertical-spindle grinding machine with a round table. The constant linear velocity gantry vertical-spindle grinding machine with the round table comprises a gantry transverse beam (1), a Z-axis servo feed system (2), a grinding head (3), a rotary working table (4), a rotary support (5), a rotary table servo power system (6), a sliding way table (7), ball screws (8), an X-axis servo feed power system (9), a base (10), gantry stand columns (11), an upright sliding way (12), reinforcing ribs (13) and a linear guideway (14). According to the constant linear velocity gantry vertical-spindle grinding machine with the round table, a gantry structure is adopted, the stability of the vertical-spindle grinding machine with the round table is improved, and the abrasive machining range of the grinding machine with the round table is enlarged. Besides, the constant linear velocity gantry vertical-spindle grinding machine with the round table can achieve constant linear velocity grinding, and machining accuracy and ground patterns of the machined surface of a rotary workpiece can maintain consistent.

Description

technical field [0001] The invention relates to a constant linear speed gantry vertical shaft circular table grinder, which can especially meet the high-precision grinding processing requirements on the surface of large rotary workpieces. Background technique [0002] At present, the known vertical axis plane circular table grinder includes a base, a vertical guide rail, a grinding head, a rotary table, a feed system for the table, and a rotary system for the table. The base and the vertical guide rail are cast parts and are rigidly connected together; the grinding head can move up and down through the feed system on the vertical guide rail to realize the control of the grinding thickness of the workpiece by the grinding head; the grinding head rotates at high speed and rotates at the same time The round table drives the workpiece on it to make a rotary motion, and the relative rotation between the grinding head and the workpiece is the grinding action; the round table feed ...

AI Technical Summary

Problems solved by technology

[0003] The grinding motion of the common cylindrical table grinder is the synthesis of the rotation of the rotary table and the rotation of the grinding head. During the feeding motion of the longitudinal feed system, the grinding head moves to the center of rotation of the workpiece. Since the rotational speed of the rotary table is a constant value, The grinding line speed of the grinding point will continue to decrease, which causes the surface grinding accuracy and grinding pattern to be inconsistent between the edge of the workpiece and the center of rotation, and the ideal surface processing quality cannot be achieved; the vertical guide rail and the base The connected structure restricts the processing scale of the workbench, even if the vertical axis round table is a large-size workbench, its stability is not ideal
