Problems solved by technology

[0005] The present invention provides a control method for honing processing in order to solve the problem that the cutting pressure is affected by the contact area between the sand bar and the workpiece in the prior art, and the reticulation pattern at the reversing position does not overlap in the normal processing stage of constant pressure feed. , can obtain stable honing beat and texture groove depth, and the removal of the workpiece allowance is triangular, thus obtaining higher geometric accuracy than constant pressure feeding, and at the same time, it can realize the sand bar staying at the upper and lower reversing positions of the sand bar The position coincides, so that the processed net pattern is neat and beautiful

Embodiment 1

[0043] Such as figure 1 As shown, a control method for honing processing, which controls the feed of the sand bar at a speed, includes the following steps:

[0044] S1. Set the abutment force and abutment speed, and determine the abutment position P by setting the abutment force t ;The current abutment speed is inversely proportional to the current abutment force;

[0045] S2, a rough honing: the sand bar starts from the starting position S t at fast forward speed V 0 advance to the abutment position with the P t The distance is the position P of the protection gap △DS 10 , and then change the speed to advance to the abutment position P t The distance is the position P of the elastic deformation correction value △DT 11 , at the working speed V 2 Processing set size to position P 12 ; The step S2 further includes:

[0046] S21, the sand bar from the position P 10 continue at the fast-forward rate V 0 Advance protection gap △DS 1 to position P 1ds ;

[0047] S22. The...

Abstract

The invention provides a control method for hone machining. Feeding of nail files is controlled at the speed. The one-time machining process comprises primary coarse honing, returning of the nail files, secondary coarse honing and coarse honing completion. The distance between every two adjacent honed nail files is identical to that the single-stroke rotation distance of the nail files. Accordingto the control method for hone machining, feeding of the nail files is controlled at the speed, and the situation that the cutting pressure intensity during fixed-pressure control is influenced by thecontact area of the nail files and workpieces is avoided. Through reasonable matching of distribution of the nail files, reticulate pattern angles, stroke distances and rotation speeds, the retentionpositions of the nail files during reciprocation reversing during honing are overlapped.

Description

technical field [0001] The invention relates to the technical field of honing, in particular to a method for controlling honing processing. Background technique [0002] In the batch honing process of engine cylinder block and cylinder liner inner hole, the dimensional tolerance range of the same product before honing and after honing is very small. The fluctuation range of groove index is small. [0003] When honing the same product, under the condition that the pre-honing size, honing allowance, reciprocating speed, spindle speed, and auxiliary actions are the same, the factor that determines the fluctuation range of the honing beat is the cutting pressure. Keeping the cutting pressure stable will ensure that the honing beat and net The groove index can also remain stable. During honing, since the contact area between the sand bar and the workpiece is variable, under the constant pressure feed control of the sand bar, when the gravel becomes blunt and the surface roughne...
