A mechanically augmented spindle tool release system

Abstract

The invention discloses a mechanical reinforcement type spindle knife loosening system. The mechanical reinforcement type spindle knife loosening system is characterized in that an air power unit used for providing knife loosening power, a stroke adjusting unit used for adjusting the stroke position of a knife loosening point, a reinforcement knife hitting unit used for achieving knife loosening power multiplication, and a stroke detection unit used for providing state signals for a spindle knife hitting disk are included, one end of the air power unit is connected with a spindle box, the other end of the air power unit is connected with one end of the reinforcement knife hitting unit through the stroke adjusting unit, and the other end of the reinforcement knife hitting unit is arranged on the outer side of the spindle knife hitting disk. The mechanical reinforcement type spindle knife loosening system has the advantages that spindle breakdowns caused by hydraulic oil leakage of a traditional hydraulic and gas-liquid boosting knife hitting system are avoided, the needed knife loosening force is small, the service life of a spindle can be prolonged greatly, the controllability is good, the modular design is used, the reliability and the production efficiency of the complete machine of a machine tool are improved, the automatic degree of the machine tool is guaranteed, the work of subsequent mounting, adjusting, repairing and the like is made to be simple and convenient.

Description

technical field [0001] The invention relates to a spindle tool release system of a numerically controlled machining center, in particular to a mechanically boosted spindle tool release system. Background technique [0002] With the continuous and rapid development of the national economy, the continuous improvement of the overall level of domestic productivity and the continuous advancement of the process of global economic integration, the diversification and individualized demands of various industries and life products are also increasing, thus at the source. The machining efficiency and reliability of the parent machine (NC machine tool) put forward higher requirements. For CNC machine tools, the spindle drive system is also the main drive system. Its performance not only determines the surface quality of the workpiece, but also has a relatively high failure rate due to its complex structure and often organic, electrical, and pneumatic linkages. Therefore, The stability...

Problems solved by technology

Under normal circumstances, the main cause of damage to the spindle bearing is the loss and deterioration of the bearing grease caused by the leakage of the hydraulic oil of the spindle tool cylinder and annihilation of the bearing, or the long-term and frequent direct action of the spindle tool loosening force on the bearing. bearing damage
