Direct drive type honing device

Abstract

The invention provides direct-drive honing equipment, which comprises an outer shell, a direct-drive linear motor and a direct-drive rotating motor, wherein the direct-drive linear motor and the direct-drive rotating motor are mounted in series; the direct-drive linear motor is mounted at the rear part of the outer shell, and drives the main shaft of the honing equipment to make a reciprocating movement; the direct-drive rotating motor is mounted at the front end of the outer shell, and drives the main shaft of the honing equipment to make a rotating movement. The honing equipment further comprises a direct-drive electric cylinder; the direct-drive electric cylinder drives the honing equipment to make a radial feed movement. The honing equipment adopts the direct-drive linear motor, the direct-drive rotating motor and the electric cylinder, thereby realizing that the driving of the honing function of the honing equipment to the three movements entirely adopts the direct-drive technology, performing the electromechanical integration whole optimization composite design, and overcoming the defect in the prior art that the hydraulic drive system and the regular motor are adopted for driving.

Description

technical field [0001] The present invention relates to a honing device, in particular to a direct-drive honing device, and in particular to an improvement of a driving device of the direct-drive honing device. Background technique [0002] The implementation of traditional honing equipment drivers is relatively complicated, see figure 1 , wherein the honing equipment needs three types of motion drives, (1) the reciprocating motion of the honing equipment (the direction indicated by the arrow Y in the figure) - usually realized by the hydraulic system driving the pressure cylinder; (2) the rotation of the honing equipment (the direction shown by the arrow Y in the figure) (direction shown by arrow ω) motion——is realized through mechanical transmission by servo motor; or conventional electromechanical solutions, i.e., as figure 1 As shown, as the ejector rod of the honing equipment moves linearly in the X direction, the cone surface of the standard honing head squeezes the ...

AI Technical Summary

Problems solved by technology

[0003] As mentioned above, the hydraulic system is usually used to drive the pressure cylinder to realize the reciprocating motion of the honing equipment. The hydraulic system has the defects of slow response speed and large hysteresis, and requires additional pressure generating equipment, which is bulky and complex in structure. Different specifications and models of honing equipment need to design different hydraulic systems to match, the design and manufacturing cycle is long, the adaptability is poor, and the cost is also high

In addition, the hydraulic system is also difficult to control by means of numerical control
