Abstract

The invention relates to a device for rapidly assembling a stud. The device is characterized by comprising a threaded ejector rod (1), an internal threaded sleeve (4), a first cross rod (2) and two second cross rods (3), wherein the threaded ejector rod (1) comprises a rod head (11) and an external threaded rod body (12), the upper part of the threaded ejector rod (1) is provided with the rod head(11), and the external threaded rod body (12) is connected below the rod head (11); and a horizontal through hole is formed in the rod head (11), the first cross rod (2) penetrates through the through hole, and the middle part of the first cross rod (2) is fixed in the horizontal through hole in the rod head (11). According to the device, the installation efficiency of the stud is improved, the working intensity of workers is reduced, and the device is simple in structure and simple and convenient to operate, can effectively improve the assembly efficiency and reduce the working intensity ofthe workers.

Description

technical field [0001] The invention is a device for quick assembly of double-ended studs, which is used for quickly realizing the assembly of double-ended studs. Background technique [0002] Double stud connection has a very common application in the field of mechanical assembly. Studs are usually used where the connected parts are too thick to be connected by bolts or where screw connections are not suitable for frequent disassembly, or used in the assembly of products with relatively compact structure requirements. Among them, one end of the double-ended stud screwed into the threaded hole of the connected workpiece is called the screw-in end; the other end passes through the part with a through hole, and then the nut is screwed on, and this end is called the fastening end. [0003] At present, in most assembly occasions, when the double-ended stud is screwed into the threaded hole of the connected workpiece, it is necessary to superimpose two nuts on the fastening end ...
