Oilstone feeding device of honing machine

Abstract

The invention discloses an oilstone feeding device of a honing machine, which relates to the technical field of honing machines and solves the technical problems of improving the oilstone feeding sensitivity and precision of the prior honing machine. The honing machine comprises a power output shaft and an oilstone feeding shaft, and is characterized in that the device comprises a cam, a flexiblegear with external teeth and rigid gears with internal teeth, which are sleeved sequentially from the inside to the outside; the cam is fixedly connected with a control shaft; the flexible gear is connected with the rigid gears by teeth and can be flexibly deformed along with the rotation of the cam; and each rigid gear consists of a main rigid gear and an auxiliary gear which are mutually independent and are connected with the power output shaft and the oilstone feeding shaft respectively, and the internal teeth of the rigid gears have tooth difference with the external teeth of the flexiblegear. The oilstone feeding device moves stably, causes no transient impact, and has strong bearing capacity, large transmission range, simple structure and less loss.

Description

technical field [0001] The invention relates to the technology of a honing machine, in particular to the technology of an oil stone feeding device of a honing machine. Background technique [0002] The honing machine is a device that uses oilstone to honing the surface of the workpiece. The feed control of the oilstone is related to the precision of the honing. The oilstone feeding device of the traditional honing machine adopts the chute type and the gear transmission method to control the oilstone feed. The chute-type feed uses a tapered shaft for axial movement, so that the tapered surface of the tapered shaft is used to push the oilstone seat to expand and contract radially to achieve feeding. This feeding method is simple in structure and small in size, but its feed The feeding movement is unstable, and the instantaneous impact is large, it is not easy to control the honing accuracy, and the bearing capacity is also poor; while the gear transmission feed solves the shor...

Problems solved by technology

The chute-type feed uses a tapered shaft for axial movement, so that the tapered surface of the tapered shaft is used to push the oilstone seat to expand and contract radially to achieve feeding. This feeding method is simple in structure and small in size, but its feed The feeding movement is unstable, and the instantaneous impact is large, it is not easy to control the honing accuracy, and the bearing capacity is also poor; while the gear transmission feed solves the shortcomings of the chute feed, but its transmission range is small, the structure is complex, and the volume It is also large, and the loss between the gears is also large, which will affect the machining accuracy
