A guide sleeve repair method and guide sleeve

Abstract

The invention discloses a guide sleeve repair method and a guide sleeve. The guide sleeve repair method includes the steps: 1 machining a groove in the inner wall of the guide sleeve to be repaired; 2applying adhesives into the groove and to an adhesive surface of a soft band; 3 adhering the soft band into the groove, bracing the adhered soft band by a bracing tool and cutting off the portion, larger than the perimeter of the inner wall of the guide sleeve with the machined groove, of the soft band after adhesion; 4 machining the inner diameter of the adhered guide sleeve into the size neededby a process. The depth of the groove needs to be smaller than the thickness of the soft band, and the length of the soft band needs to be larger than the perimeter of the inner wall of the guide sleeve with the machined groove. The method is simple to operate, the guide sleeve machined by the method has good adhesion effects, and cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of guide sleeve repair, in particular to a guide sleeve repair method and the guide sleeve. Background technique [0002] Such as figure 1 As shown, due to the friction of the hydraulic rod, the inner wall of the guide sleeve will be worn after long-term use. After the inner wall of the guide sleeve is worn, the movement track of the hydraulic rod will change, which will affect the guiding accuracy. At present, after the guide bush is worn out, it is usually replaced as a whole or repaired. The method of repair is to first use brush plating, electroplating or coating to make up for the worn inner wall of the guide bush, and then through turning, milling or grinding. And other processing methods make the inner wall of the guide sleeve meet the accuracy requirements of use. [0003] The above repair methods have the following deficiencies: 1. Use brush plating, electroplating or coating to make up for the wo...

AI Technical Summary

Problems solved by technology

[0003] The above repair methods have the following deficiencies: 1. Use brush plating, electroplating or coating to make up for the worn inner wall of the guide sleeve. The bonding force between the coating and the inner wall of the guide sleeve is poor, and the coating is prone to cracks or peeling off, which affects 2. If the size of the inner wall of the worn guide sleeve is large, after coating, due to the limitation of the size of the inner wall of the guide sleeve, subsequent processing cannot be processed on a grinding machine, which makes the above method have limitations
