Detailed Description
The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the invention, but are not intended to limit the invention in any way. It should be noted that it would be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit of the invention. All falling within the scope of the present invention.
Example one
As shown in fig. 1, the tubular adhesive structure provided by the present invention comprises a connecting cylinder 1, a first pipe 5, a second pipe 6 and a positioning wire 2. Both ends of connecting cylinder 1 all are to open the setting, and the axial interval along connecting cylinder 1 is equipped with preceding locating hole 3 and back locating hole 4 on the lateral wall of connecting cylinder 1.
One possible implementation is: the positioning wire 2 penetrates into the connecting cylinder 1 from the front positioning hole 3 and penetrates out of the connecting cylinder 1 from the rear positioning hole 4. Another possible implementation is: the positioning wire 2 penetrates into the connecting cylinder 1 from the rear positioning hole 4, and penetrates out of the connecting cylinder 1 from the front positioning hole 3. The portion of the positioning wire 2 inside the connecting cylinder 1 corresponds to a rib capable of positioning, and therefore, the positioning wire 2 inside the connecting cylinder 1 is preferably attached to the inner wall of the connecting cylinder 1.
The first pipe 5 extends into the connecting cylinder 1 from one open opening of the connecting cylinder 1, the second pipe 6 extends into the connecting cylinder 1 from the other open opening of the connecting cylinder 1, and one end of the first pipe 5 extending into the connecting cylinder 1 is contacted with one end of the second pipe 6 extending into the connecting cylinder 1. The first pipe fitting 5 and the second pipe fitting 6 are respectively connected with the connecting cylinder 1 in a gluing mode, and the first pipe fitting 5 and the second pipe fitting 6 are respectively connected with the positioning wire 2 in a gluing mode. The thickness of the adhesive layer of the first pipe element 5 and the second pipe element 6 and the connecting cylinder 1 is equal to the diameter of the positioning wire 2.
Specifically, the material of the connector barrel 1 includes a composite material or a metal material. The material of the positioning wire 2 includes nylon or polyester polyethylene. It should be noted that: due to the mature production process of the wire, the diameter of the wire has very high precision and low cost, and the high installation precision when the wire is inserted into the pipe and the accurate glue thickness when the wire is bonded can be ensured.
In the case of epoxy resin as an adhesive, the thickness of the common glue is 0.3mm, the diameter of the positioning wire 2 should be 0.3mm, and the pipe diameter of the connecting cylinder 1 is 0.6mm larger than that of the first pipe 5 and the second pipe 6.
Since the positioning wire 2 is made of polymer, the strength thereof is low, so that it is very easy to remove the excessive positioning wire 2. And the polymer has certain elasticity and ductility, so when the pipe needing to be bonded has larger processing size deviation, the pipe can be connected into the connecting cylinder 1 by extruding the wire to complete bonding, and the machining parts cannot be matched under the condition.
Can solve the problem that conventional machine tooling location bank reduced the area of gluing through location wire rod 2, reach the effect that increases the gluey intensity.
Further, the cross section of the positioning wire 2 is circular, and under the condition of perfect fit, the positioning wire 2 is in line contact with the connecting cylinder 1, the first pipe fitting 5 and the second pipe fitting 6, the direct contact area of the positioning wire 2 tends to zero, and the bonding area is not affected at all, so that the bonding strength tends to the theoretical maximum bonding strength.
The positioning wires 2 are provided at equal intervals along the circumferential side of the connecting cylinder 1 on the side wall of the connecting cylinder 1. Correspondingly, the front positioning hole 3 and the rear positioning hole 4 are equally spaced along the peripheral side of the connecting cylinder 1 on the side wall of the connecting cylinder 1 to form a plurality of groups, so that the installation of a plurality of positioning wires 2 on the connecting cylinder 1 is satisfied, and the plurality of positioning wires 2 are symmetrical to the central axis of the connecting cylinder 1.
Both the first and second pipe elements 5, 6 penetrate coaxially into the connecting cylinder 1. One end of the first pipe fitting 5 extending into the connecting cylinder 1 extends to the middle parts of the front positioning hole 3 and the rear positioning hole 4, and one end of the second pipe fitting 6 extending into the connecting cylinder 1 extends to the middle parts of the front positioning hole 3 and the rear positioning hole 4. When in bonding, the front positioning hole 3 and the rear positioning hole 4 can be used as glue injection ports.
Because the inner wall of the connecting cylinder 1 is provided with the positioning wire 2, and the diameter of the positioning wire 2 is equal to the thickness of the adhesive layer between the first pipe fitting 5 and the second pipe fitting 6 and the connecting cylinder 1. With the help of the positioning wires 2 which are uniformly distributed on the inner wall of the connecting cylinder 1, the high precision of the positioning wires 2 is combined, the problem that the first pipe fitting 5 and the second pipe fitting 6 are positioned during bonding is solved, and the purpose of reducing assembly errors is achieved.
According to the tubular gluing method provided by the invention, the gluing method comprises the following steps:
s1, sequentially penetrating and fixing a positioning wire 2 through a front positioning hole 3 and a rear positioning hole 4 on a connecting cylinder 1.
And S2, coating adhesives on the outer walls of the first pipe fitting 5 and the second pipe fitting 6.
And S3, respectively inserting the first pipe fitting 5 and the second pipe fitting 6 into the connecting cylinder 1.
S4, if glue is extruded out, directly wiping a circle around the connecting cylinder 1; if the glue is insufficient, glue is injected through the front positioning hole 3 and/or the rear positioning hole 4.
Variation example
Based on embodiment 1, according to the tubular gluing method provided by the invention, step S1 is replaced by: and (3) sequentially penetrating the positioning wire 2 through the rear positioning hole 4 and the front positioning hole 3 on the connecting cylinder 1 and fixing.
