Elastic buffering feeding device of inner diameter slicing machine and feeding method thereof

Abstract

An elastic buffering feeding device of an inner diameter slicing machine belongs to the device of automatic inner diameter slicing machines. The feeding device comprises a cutting tool driven by a main shaft motor, an X axis travelling table driven by a stepping motor and a Y axis travelling table driven by the stepping motor. The X axis travelling table is arranged above the Y axis travelling table, and a frame for chucking materials is arranged on the X axis travelling table. The present invention is characterized in that an elastic part or an elastic assembly is arranged in a delivery connecting device for controlling shift and force, arranged between the X axis travelling table and the Y axis travelling table. Control feed instantly completed is absorbed by the elastic part or the elastic assembly, so the purpose in elastically buffering feeding force is achieved. The defect that the pulse feeding is directly forced is overcome, the influence of part rigidity variation of cutting materials on cutting quality and cutting efficiency is avoided, and the adoptability of processing parameters to the cutting possibility of materials cut is improved. Thus, cutting speed is improved.

Description

Technical field: [0001] The invention belongs to a device of an automatic inner circle slicer, and in particular relates to a feeding device and a feeding method of the automatic inner circle slicer. Background technique: [0002] The inner circle slicer is the most commonly used processing equipment in the plane cutting of sintered NdFeB rare earth permanent magnet materials. It includes a semi-automatic inner circle slicer, a fully automatic inner circle slicer, a fully automatic inner circle slicer including a microcomputer control system, a cutting tool driven by a main motor, and a feeding device. The feeding device includes an X-axis movement driven by a stepping motor. The worktable, the Y-axis movable worktable driven by the stepping motor, the X-axis movable worktable is arranged above the Y-axis movable worktable, and the stepping motor driving the X-axis movable worktable is arranged on the X-axis movable workbench. [0003] In the traditional manual control cutt...

AI Technical Summary

Problems solved by technology

[0016] The stepper motor works in a rigid connection mode, and it is rigid to give force. The step amount of each step is applied to the cutting edge of the incision slicer. In practice, there are the following shortcomings: when the stepping feed speed is set relatively low, the two The working conditions of the workers are basically similar, and the cutting speed (cutting area per unit time) is relatively low under such working conditions, which is 15-30% lower than the manual cutting speed on average; There are a large number of slicers, and all parameters are taken within a relatively safe and conservative range. Compared with manual slicers, the cutting speed is about 20% lower
