Honing and dual-feed mechanism of honing machine

Abstract

The invention relates to a honing and dual-feed mechanism of a honing machine. The honing and dual-feed mechanism comprises a box body, a finish honing propping rod, a rough honing propping rod, a first driving device, a second driving device, a first transmission mechanism and a second transmission mechanism; the finish honing propping rod and the rough honing propping rod are movably with the box body in the vertical direction; the first driving device is arranged above the box body and provides power for the finish honing propping rod to move in the vertical direction; the second driving device is arranged in the box body and provides power for the rough honing propping rod to move in the vertical direction; the first driving device is in transmission connection with the finish honing propping rod by the first transmission mechanism; the second driving device is in transmission connection with the rough honing propping rod by the second transmission mechanism; and the finish honingpropping rod is sleeved with the rough honing propping rod. The honing and dual-feed mechanism of the honing machine further comprises a guiding mechanism arranged in the box body and used for guidingthe finish honing propping rod and the rough honing propping rod to move in vertical direction. The honing and dual-feed mechanism of the honing machine is lighter in overall structure, high in precision, high in part universality and low in maintenance cost, adopts modular design and is suitable for batch production.

Description

technical field [0001] The invention relates to a honing double-feed mechanism of a honing machine. Background technique [0002] In the past, double-feed honing machines used hydraulic cylinders to push out ejector rods, or the rough honing feed mechanism and the fine honing feed mechanism were separately arranged inside and outside the box. The feeding method of the hydraulic cylinder driving the ejector pin can only realize constant pressure honing, not quantitative feed honing, let alone constant pressure-quantitative feed honing. When the honing stone is in contact with the workpiece, there is no speed control, nor is there any control on the amount of ejection. The action is too rough and simple, which may easily cause the honing stone to chip, the workpiece to be stuck, or even twist the honing head and honing rod. It is difficult to obtain High-quality honing accuracy is also difficult to obtain high-efficiency honing processing. [0003] In order to overcome the a...

Problems solved by technology

Although the use of this mechanism has improved the problem of the movement accuracy of the ejector rod, due to its double-guided structure, the problem of over-positioning of the structure-guided structure has occurred, resulting in unstable processing and abnormal processing products; in addition, its The overall structure is not compact enough, the design is unreasonable, the production is difficult and costly
