【Embodiment】
The present invention is described in further detail below in conjunction with the accompanying drawings：
Referring to Fig. 1-5, the present invention is used to bond insulating cylinder and metal joint attachment structure, including the insulating cylinder 1 being connected
With metal joint 2；Some gummosis grooves 3, Mei Geliu are offered on the madial wall of one end that metal joint 2 is connected with insulating cylinder 1
The two ends correspondence position of glue groove offers the through hole 4 for making unnecessary bonded adhesives and bubble outflow；Insulating cylinder 1 and metal joint 2
Offered on the outer wall of connected one end it is corresponding with the position of gummosis groove 3 of metal joint end, and width identical be bonded
Groove 5；Metal joint 2 is connected with the junction 6 of insulating cylinder 1 using interference fit.The internal diameter of gummosis groove 3 be 188.8 ±
0.2mm, length is 50mm, and groove-root diameter is 192.8 ± 0.2mm, and width is 10~13mm, and depth is 0.3~0.5mm.Through hole 4
A diameter of 5mm.The external diameter for being bonded groove 5 is 189 ± 0.1mm, and length is 50mm, and groove-root diameter is 185 ± 0.1mm, width
For 10~13mm, depth is 0.3~0.5mm.
The working depth of insulating materials of the present invention bonding groove is that 0.3-0.5mm, width are 10-13 millimeters；Metal joint
Groove processing depth is 0.3-0.5 millimeters, width is 10-13 millimeters, and each groove processing rubber flow holes, facilitates later stage bonding to squeeze
Glue；
The bonding site of metal joint is processed；The inside bonding site of metal joint, internal diameter is machined to m millimeters,
50 millimeters of processing length, and three gummosis grooves are uniformly processed, bottom land footpath is m+4 millimeters, and width is 10 millimeters, and in each stream
