Abstract

本发明是一种由换能器、变幅杆、清洗捧及超声频电发生器组成的插入式超声清洗装置。这种装置所产生的声强比一般容器式超声清洗机强。用于油泵油嘴深盲孔或其他具有深盲孔的工件的清洗，解决现有容器式清洗器洗不净的深小孔，尤其是深盲孔的清洗问题。清洗棒易更换、便于维修，与一般容器式超声清洗机比较，使用寿命长，维修费用低。

Description

本发明属于超声清洗装置。
一般超声清洗所用的设备是做成容器式的，(美国专利3，293 456)在清洗容器的底部或周边安装超声换能器，被清洗件置于容器中的清洗液进行清洗，或者用一种浸设式换能器置于容器中。油泵油嘴用现有的上述设备进行超声清洗时，只能洗净油嘴的直径较大而浅的内孔上部污物，洗不净深盲孔部分。此外，上述一般清洗装置，清洗容器产生超声空化腐蚀，维修费高，适于表面清洗，不适用于深孔，尤其是深盲孔的清洗，因为声强低，微冲流的搅拌洗涤作用受限制。
本发明的目的是解决深盲孔的清洗问题。
本发明的要点是，采用了夹心式压电换能器，变幅杆及清洗棒组成的超声清洗装置。三个部分都用螺丝连结。在清洗棒端产生比较高的声强。被清洗件侵入装有清洗液的普通容器中，而清洗棒直接插入被清洗件的盲孔中进行超声清洗。能在一分钟内洗净盲孔中的污物。由于本发明所用清洗棒与变幅杆的连接采用螺丝连接，所以易于更换，成本低、维修方便。夹心式压电换能器用对称结构。本发明不限于油泵油嘴盲孔清洗，也可用于一般深盲孔(直径4mm～6mm深达100mm的小孔)的零部件超声清洗。
图1是发明的一个具体实施例的正视图。图2是侧视图。
本发明的主要部件是：它包括超声频电发生器1，夹心式压电换能器2，阶梯形变幅杆3及清洗棒4。变幅杆可以是圆截面或矩形截面。外形轮廓线可以做成指数曲线形或悬链线形，也可以做成圆锥形等。变幅杆的下端面可以安装单根或多根的清洗棒，棒长不受半波长所限制。棒的直径及数量决定于被清洗件的孔径、孔深及形状。清洗棒端侧面带有一定圆弧使声按一定角度辐射到孔内壁和孔底。清洗棒轴向中心有孔，棒端头及端头侧面圆弧上的孔与中心轴孔相通。清洗棒的另一端和变幅杆用螺丝连接、在变幅杆的端侧面设有进水管接头5，孔与清洗棒轴孔相通，清洗液由进水孔压入，从清洗棒下端头的孔流出，在强超声空化作用下洗掉粘在孔壁及孔底的污物，并由清洗液带出孔外。振动系统的频率根据清洗棒的长短可以在16KHz-20KHz范围内工作。
