Problems solved by technology
[0003] In the disassembly process of the existing press-fit pipe joints, due to the large press-fit tightness and no suitable force application point, the press-fit pipe joints are usually taken out directly with a vise or pried out with a screwdriver, etc. Such methods will damage the parts , so that this type of press-fit pipe joint cannot be reused, the operation is difficult, and the cost is high

Embodiment Construction
[0010] As shown in the figure, the dismantling tool of the press-fit pipe joint includes a claw 1, an adjustment handle 6, a shaft 7, and a lifting hammer 8. There are multiple claws 1, which are evenly distributed and mounted on the shaft 7 along the axial direction. , the adjustment handle 6 and the lifting hammer 8 pass through the shaft 7 and can move on the shaft 7, the other end of the shaft 7 is provided with a limit block 9 whose size is larger than the inner diameter of the lifting hammer 8, and the adjustment handle 6 is close to one side of the claw 1 The side is conical, and the end of the claw 1 is provided with an inclined surface and matched with the conical shape of the adjustment handle 6, and the other end is provided with a claw that cooperates with the sealing groove of the pipe joint 11 to be disassembled. There are two jaws 1. The limiting block 9 is installed on the shaft through a screw 10 .

The invention relates to a withdrawal tool for a press-in pipe joint. The withdrawal tool comprises a plurality of clamp claws 1, an adjusting handle 6, a shaft 7 and a lifting hammer 8, wherein the clamp claws 1 are uniformly mounted on the shaft 7 in a hinged way along the axial direction; the adjusting handle 6 and the lifting hammer 8 penetrate through the shaft 7; a limiting block 9 is arranged at the other end of the shaft 7; one side of the adjusting handle 6 is conical; and a claw matched with a sealing groove of a pipe joint 11 to be detached is arranged at the other end of the adjusting handle 6. According to the withdrawal tool disclosed by the invention, when the pipe joint is withdrawn, destructive operation by using tools such as jaw vices is avoided and the quick and effective withdrawing process of the pipe joint is realized; and in addition, the pipe joint is prevented from being damaged in an any form, the simplicity in operation is realized and the cost is saved.
Description
technical field [0001] The invention relates to a dismantling tool, in particular to a dismantling tool of a press-fit pipe joint. Background technique [0002] The press-fit pipe joint is divided into two structures: the first one is an outer diameter press-fit pipe joint in which one end of the pipe joint has an interference fit with the machine body, and the other end has a clearance fit with the machine body, and an O-ring seal is used to ensure the sealing effect of the oil circuit. The second type is an inner diameter press-fit pipe joint in which one end of the pipe joint has an interference fit with the body, the other end has a clearance fit with the body, and an O-ring seal is used to ensure the sealing effect of the oil circuit. [0003] In the disassembly process of the existing press-fit pipe joints, due to the large press-fit tightness and no suitable force application point, the press-fit pipe joints are usually taken out directly with a vise or pried out with...
