Automatic feeding ultrasonic honing machine

Abstract

The invention relates to an automatic feeding ultrasonic honing machine which comprises an energy converter, a rotating shaft, a honing head arranged below the rotating shaft and an oil stone arranged on the honing head. The ultrasonic honing machine comprises a detecting unit used for measuring the expansion degree of the oil stone, a controller connected with the detecting unit and used for controlling the rotating speed of the rotating shaft, a power unit connected with the controller and used for controlling the rotating shaft to rotate, and a feeding unit connected with the controller and used for controlling feeding. When the detecting unit detects that the expansion degree of the oil stone meets the requirement, the controller controls the rotating shaft to rotate and adjust the rotating speed of the rotating shaft, and meanwhile the feeding unit is controlled to conduct feeding. Compared with the prior art, starting and closing of honing can be automatically controlled, and the automation degree is high; the power unit and the feeding unit are controlled through the controller so that the rotating speed of the rotating shaft can be better matched with the feeding amount of honing liquid, and the honing quality is improved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic honing, in particular to an automatic feeding ultrasonic honing machine. Background technique [0002] Honing is widely used in the finishing or finishing of holes of various shapes, and can also process workpieces with special requirements on the surface, such as cylinder liner holes, connecting rod holes, oil pump nozzles and hydraulic valve body holes, etc. The surface requires cross-groove texture for oil storage for lubrication. In addition, due to different working conditions, parts have different requirements for the distribution and depth of grooves. [0003] There are two major problems in ordinary honing: (1) The efficiency of ordinary honing is low, especially when honing thin-walled parts, tough materials and hard and brittle materials, the processing efficiency is extremely low. When honing tough materials such as copper, aluminum, and titanium alloys, the whetstone is easily blo...

AI Technical Summary

Problems solved by technology

[0003] There are two major problems in ordinary honing: (1) The efficiency of ordinary honing is low, especially when honing thin-walled parts, tough materials and hard and brittle materials, the processing efficiency is extremely low

When honing tough materials such as copper, aluminum, and titanium alloys, the whetstone is easy to clog, the surface quality is poor, and the processing efficiency is extremely low

(2) When feeding at a constant pressure, the expansion pressure of the oil stone changes greatly; when feeding at a fixed distance, the expansion pressure of the oil stone is controlled by the experience and feel of the operator, resulting in abnormal damage to the oil stone, deformation of the workpiece and even scrapping

[0007] However, there is still a big defect in the existing ultrasonic grinding technology, that is, the operator cannot leave the operator during the honing process, because the continuous vibration of the ultrasonic generator will make the oil stone continue to expand, so that the honing marks are too deep, so it is necessary to Someone keeps turning the ultrasonic generator on and off, low automation
