Stud assembly and disassembly tool

Abstract

The invention belongs to the technical field of automobile parts, and provides a stud assembly and disassembly tool, which comprises an opening and closing mechanism and a driving mechanism for driving the opening and closing mechanism to be opened and closed, wherein the opening end of the opening and closing mechanism is provided with internal thread matched with external thread of the stud; and the stud is in screw joint with the internal thread and is clamped via the driving mechanism. Through arranging the opening and closing mechanism which is matched with the stud and the driving mechanism for driving the opening and closing mechanism, the internal thread of the opening and closing mechanism clamps the stud; as the internal thread and the external thread of the stud are matched and clamped via the driving mechanism, sliding of the stud and the opening and closing mechanism during the assembly and disassembly process can be prevented, thread of the stud can be protected, wear debris is not generated, the thread can be protected, the stud can be reused after assembly and disassembly, and the utilization rate of the element is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical assembly, and in particular relates to a double-ended stud disassembly tool. Background technique [0002] The double-ended stud looks like a cylinder, and it cannot be disassembled with tools such as sleeves. Usually, pliers, such as pliers, are used to clamp the double-ended stud, and the jaws are used to act on one end of the double-ended stud. The clamping force bites the double-ended stud and reversely rotates so that the double-ended stud can reversely rotate with the pliers until the double-ended stud is taken out of the mounting hole, and the assembly and disassembly is completed. [0003] In this method, the jaws of the pliers directly act on the threaded surface of the double-ended stud, and the thread of the double-ended stud is not protected. The rigid contact between the middle jaw and the double-ended stud is prone to relative movement, resulting in damage to the stud, which cann...

[0003] In this method, the jaws of the pliers directly act on the threaded surface of the double-ended stud, and the thread of the double-ended stud is not protected. The rigid contact between the middle jaw and the double-ended stud is prone to relative movement, resulting in damage to the stud, which cannot be reused, reduces the utilization rate of components, and the debris generated will also cause pollution; at the same time, the clamping force between the jaws is used to occlude The clamping force depends on the strength of the operator's hand during this process. If the clamping force cannot be provided enough, the disassembly of the stud cannot be completed, which is limited by the operator's personal factors. The disassembly process is limited, which affects the process flow; and use a large enough clamping force to bite one end of the double-ended stud and rotate it in reverse to disassemble. In this process, the clamping force cannot always be kept stable and large enough, and the thread will also be damaged.
