Problems solved by technology
Its advantages are large amplitude and high material removal rate, which is conducive to improving productivity; the disadvantage is that the structure is complex, the manufacturing cost is high, the installation and adjustment are difficult, and the energy loss is large during the transmission process; at the same time, due to the large amplitude, it will cause damage to the honing surface. It is easy to remove in the subsequent honing process, so the machining accuracy is low, suitable for precision semi-precision machining, but not suitable for applications in the field of ultra-precision machining

The invention discloses an ultra-precise ultrasonic honing device which comprises a current collecting ring, a honing head body, a hone base and an energy converter, wherein the current collecting ring is mounted on a spindle; an ultrasonic power supply is introduced from one side of the current collecting ring through a carbon brush; the other side of the current collecting ring is connected to the energy converter through a lead; the hone base is mounted on the honing head body; the hone base is in clearance fit with a mounting slot of a honing head; and the energy converter is directly placed in the hone base. The honing precision of an improved honing head is greatly higher than the honing precision of a traditional ultrasonic honing head. The honing precision of the improved honing head can reach IT3-4 while the honing precision of the traditional ultrasonic honing head is IT5-6. The surface roughness and the shaping precision of the ultra-precise ultrasonic honing device both reach nanometer level and are greatly higher than the surface roughness and the shaping precision of a traditional ultrasonic honing method.
Description
technical field [0001] The invention relates to an ultra-precision ultrasonic honing device, which belongs to the technical field of honing processing. Background technique [0002] Honing is an important method used to improve the dimensional accuracy and shape accuracy in the fields of hole processing, plane processing, and outer circle surface processing. It is widely used in places such as automobile engines and hydraulic components that require high precision in the shape of inner holes, planes, and outer circles. [0003] Ultrasonic honing is a combination of traditional honing methods and ultrasonic machining. After the introduction of ultrasound into traditional honing, the honing efficiency can be greatly improved. At the same time, because ultrasonic honing is an intermittent cutting process, the honing force is small, and the oil stone is not easy to block during honing. , the honing temperature is lower; thus it is easy to achieve better surface quality.
