Description

TECHNICAL FIELD

[0001] The utility model relates to QC joint assembly technical field, concretely relates to QC joint press fitting device. BACKGROUND

[0002] In the industrial manufacturing field, QC joint (quick connector) as an innovative pipeline connecting device, with its significant advantage that it can realize pipeline quick connection and disconnection without the aid of tools, becomes the ideal choice in many industrial scenes. A kind of QC joint of the prior art is composed of base, O-ring and connector main body. Among them, the bottom end of the connector main body is inserted and fixed on the base;O-ring is arranged between the contact surface of the connector main body and the base, for sealing the connecting part of the two. In the production process of QC joint, after the bottom end of the connector main body is inserted into the base, in order to ensure that the connector main body and the base can be assembled in place, the two need to be pressed by press fitting device. The function of press fitting device is to realize the tight and firm connection between the connector main body and the base by applying appropriate pressure.

[0003] However, QC joint faces diversified needs in actual application, which leads to the rich diversity of the pipe body shape of the connector main body. Common pipe body shapes of the connector main body include T-shaped, the transversely extended pipe part of which can be conveniently connected with other pipelines;vertically upwardly extending pipe body, which is suitable for some occasions with relatively compact space layout;and obliquely upwardly extending pipe body, which can meet the needs of specific installation angle. The traditional press fitting mode of press fitting device is usually to directly contact with the top end of the connector main body and press down, which is suitable for press fitting the connector main body with vertically upwardly extending pipe body. However, if used for press fitting the connector main body with other pipe body shapes, problems will follow. For example, for the connector main body with T-shaped pipe body, the direct pressing down of press fitting device will contact with the transversely extended pipe part, and the transversely extended pipe part directly bearing the pressing force is easy to cause the outer wall of the pipe body to be pressed and injured, thereby affecting the quality of QC joint. For the connector main body with obliquely upwardly extending pipe body, the pressing direction of press fitting device does not match the oblique direction, and the pressure cannot be evenly distributed at the connecting part of the connector main body and the base, but is concentrated on the local outer wall of the pipe body of the connector main body, causing the local pressure of the pipe body to be too large, thereby easily causing damage to the outer wall of the pipe body and affecting the quality of QC joint.

[0004] Therefore, in order to overcome the defects of traditional press fitting device in press fitting QC joints with different shapes and improve the production quality of QC joint, it is necessary to develop a QC joint press fitting device specially used for press fitting the connector main body and the base.

[0040] As shown in Figure 2As shown in the first and third pressing heads 2 from the left, in the third embodiment of the pressing head 2, the pipe portion 41 of the corresponding joint body 4 of the pressing head 2 is arranged to extend obliquely upward. The pressing head 2 comprises two arc-shaped pressing arms 21. At least one clearance groove 22 is formed between the two pressing arms 21, and one of the clearance grooves 22 is used for allowing the top end of the corresponding pipe portion 41 to pass through. In this way, when the pressing arm 21 contacts and exerts pressure on the plug-in portion 42 of the corresponding QC joint, the top end of the obliquely upward extending pipe portion 41 of the corresponding QC joint passes through the one clearance groove 22 accordingly, which effectively avoids the pressing head 2 from contacting and exerting pressure on the outer wall of the oblique pipe portion 41, thereby preventing the pipe portion 41 from being damaged.

[0041] Referring to Figure 2 As shown in the second and fourth pressing heads 2 from the left, in the second embodiment of the pressing head 2, the pipe portion 41 of the corresponding joint body 4 of the pressing head 2 is arranged to extend obliquely upward. The pressing head 2 comprises one arc-shaped pressing arm 21. One clearance groove 22 is formed on both sides of the pressing arm 21.
