Description

Technical field [0001] The invention relates to a honing machine tool, in particular to a honing machine main shaft reciprocating follow-up control toothed belt driving device. Background technique [0002] The main shaft of the honing machine tool needs to do reciprocating motion during the honing process. The reciprocating digital control technology of the main shaft of the honing machine tool is the core manufacturing technology of the honing machine tool, which determines the performance of the honing machine tool and the level of honing technology. [0003] At present, the reciprocating motion of the spindle of the high-end honing machine tool has been numerically controlled. There are two control and driving methods for the reversing control system of the hydraulic cylinder of the reciprocating spindle. The position reversing closed-loop control drive system realizes the numerical control of the spindle reversing; the second is to use a special special honing rotary va...

Problems solved by technology

[0004] Among the above two main shaft reciprocating and reversing control systems, the electro-hydraulic position and reversing closed-loop control system composed of the electro-hydraulic servo proportional valve and the main shaft displacement sensor, the electro-hydraulic servo proportional valve is expensive and the use conditions are relatively harsh; and the special honing The reciprocating reversing control system of the special rotary valve needs to convert the linear motion of the main shaft into rotary motion and the complex closed-loop system of the rotary machine fluid position, which greatly increases the production cost of the reversing control system, and also makes the debugging and maintenance of the system Maintenance is very cumbersome
