Loading and unloading tool kit for double-end stud

Abstract

An assembling and disassembling tool kit for a double-end stud is composed of an installing tool and a disassembling tool, the installing tool comprises three types, namely a low-torque installing tool, a medium-torque installing tool and a high-torque installing tool, and the disassembling tool is of a single type. After the double-end stud is mounted through the mounting tool, the static friction force between the mounting tool and the double-end stud can be quickly eliminated only by reversely screwing the mounting tool, so that the dynamic friction force between the mounting tool and the double-end stud is far lower than the static friction force between the double-end stud and a threaded hole of a workpiece; it is guaranteed that the installation tool can be rapidly withdrawn from the double-end stud, and the fastening end of the double-end stud and the installation tool are effectively prevented from being clamped. When the double-end stud is disassembled through the disassembling tool, the disassembling tool and the fastening end of the double-end stud can be screwed, meshed and fixed, the threaded structure of the fastening end of the double-end stud is effectively protected against damage in the disassembling process, and the disassembled double-end stud can maintain good threaded connection performance.

Description

technical field [0001] The invention belongs to the technical field of tooling tools, and particularly relates to a set of loading and unloading tools for double-ended studs. Background technique [0002] Studs are widely used in mechanical assembly as a connecting component. The end of the stud for screwing into the threaded hole of the workpiece is usually called the screw-in end, and the other end of the stud needs to be connected with the screwing tool during its installation, so it is usually called the tightening end. [0003] At present, in the process of stud installation, the tools used are mainly composed of a screw sleeve and a fastening part. The fastening part is arranged in the screw sleeve. First, the fastening end of the stud stud needs to be screwed into the screw sleeve. The tightening end of the double-ended stud is brought into contact with the fastening parts inside the threaded sleeve, thereby generating an occlusal force. The screw-in end of the colu...

Problems solved by technology

[0006] However, when the above tool is used to disassemble the stud, after the tool hard bites the fastening end of the stud, it is easy to cause the thread structure of the fastening end of the stud to be destroyed, resulting in the screw connection of the fastening end of the stud. performance degradation or complete loss

If the screw-in end of the double-ended stud is too tightly connected to the threaded hole of the workpiece, the above-mentioned tools may also cause the fastening end of the double-ended stud to be twisted due to excessive torque when screwing the double-ended stud, resulting in The dismantling of studs was interrupted
