A processing tool for the end cover of a general-purpose large-diameter mill

Abstract

The invention relates to a machining tool for a universal type large-diameter mill end cover. The machining tool comprises a base and supporting bases; the base is of an I-shaped type; the lower end face of the base is fixedly connected with a machine tool workbench; two columns of T-shaped grooves are formed in the upper end face of the base; the supporting bases are assembled on the upper end face of the base; each supporting base comprises a chassis, a supporting mechanism and an adjusting mechanism; each supporting mechanism and the corresponding adjusting mechanism are fixedly arranged on the upper portion of the corresponding chassis; the chassis are arranged in the T-shaped grooves of the base; by means of a hinge, one end of each adjusting mechanism is connected with the corresponding chassis through a pin; and by means of a hinge, the other end of each adjusting mechanism is connected with the position, close to the corresponding chassis, of the annular face of a supporting barrel of the corresponding supporting mechanism through a pin. The machining tool for the universal type large-diameter mill end cover has the beneficial effects that the universal degree is high, and the machining tool is suitable for machining large-diameter mill end covers in various types; adjustment is convenient, installing is fast, and the workpiece clamping efficiency is improved; and in the machining process, real time adjustment can be performed according to the actual machining condition of a workpiece.

Description

technical field [0001] The invention relates to an auxiliary supporting tool for machining end caps of mills, in particular to a processing tool for universal large-diameter end caps of mills, and belongs to the field of mechanical processing auxiliary machines. Background technique [0002] In the field of mechanical processing, the diameter of the worktable of large vertical lathes is usually smaller than the maximum turning diameter of the workpiece, which is limited by the diameter of the workbench, resulting in some large-diameter workpieces that cannot be clamped effectively on the machine workbench, especially those with a diameter greater than 11m. When processing the end cover of a super-large-diameter mill, the diameter of the workpiece is much larger than that of the machine table, so auxiliary support tooling must be used to clamp the workpiece. The entire inner cavity of the end cover of the mill is inclined, with angles ranging from 7.5°, 15°, 22.5°, and 30°. D...

Problems solved by technology

[0002] In the field of mechanical processing, the diameter of the worktable of large vertical lathes is usually smaller than the maximum turning diameter of the workpiece, which is limited by the diameter of the workbench, resulting in some large-diameter workpieces that cannot be clamped effectively on the machine workbench, especially those with a diameter greater than 11m. When processing the end cover of a super-large-diameter mill, the diameter of the workpiece is much larger than that of the machine table, so auxiliary support tooling must be used to clamp the workpiece

The entire inner cavity of the end cover of the mill is inclined, with angles ranging from 7.5°, 15°, 22.5°, and 30°. During non-batch processing, it is necessary to make auxiliary tooling according to the product type, which is costly. After the tooling is used once, The available value is low and cannot be used repeatedly

[0003] Common auxiliary tooling usually adopts fixed welding, or other temporary splicing tooling, which is customized in a single piece. The angle of the workpiece that can be effectively supported is fixed and cannot be adjusted. The positioning and clamping effect is poor, and it does not have universality and other problems.
