Problems solved by technology

However, in actual production and life, many bolts are installed in relatively hidden parts, and it is difficult for operators to go deep into these parts to disassemble the bolts. Therefore, the external structure of the equipment can only be removed or the whole equipment can be turned over. It is time-consuming and labor-intensive to disassemble and assemble the bolts, which greatly reduces work efficiency.

Embodiment Construction

[0013] The following embodiments are further descriptions of the content of the present invention as an illustration of the technical content of the present invention, but the essential content of the present invention is not limited to the following embodiments, and those of ordinary skill in the art can and should know any Simple changes or substitutions of the essential spirit of the invention shall belong to the protection scope required by the present invention.

[0014] like Figures 1 to 3 As shown, an automatic bolt tightening device includes a first rotating shaft 11, a second rotating shaft 21, a first sleeve 12 and a second sleeve 22, and the first rotating shaft 11 and the second rotating shaft 21 are connected by a universal joint. The shaft 13 is connected, so that the first and second shafts 11, 21 can rotate synchronously, and the second shaft 21 can swing in any direction relative to the first shaft 11, and the length of the first shaft 11 is greater than that...

Abstract

The invention belongs to the technical field of bolt assembly and particularly relates to an automatic bolt tightening device. The device comprises a first rotating shaft, a second rotating shaft, a first casing pipe and a second casing pipe, wherein the first rotating shaft is connected with the second rotating shaft by the aid of a universal coupling; a connecting rod is arranged between the first casing pipe and the second casing pipe; one end of the connecting rod is hinged to the second casing pipe, the other end of the connecting rod is hinged to a sliding ring arranged on the external ring surface of the first casing pipe, and when the sliding ring slides, the second casing pipe can be driven by the connecting rod to swing. The first rotating shaft is relatively long, so that a bolt sleeve can extend into a relatively deep, narrow and small space; the second rotating shaft can swing relative to the first rotating shaft, the second rotating shaft is relatively short, thus, the second rotating shaft can swing more flexibly, the direction of the bolt sleeve can be adjusted conveniently, and a bolt can be mounted and dismounted in the narrow and small space.

Description

technical field [0001] The invention belongs to the technical field of bolt assembly, and in particular relates to an automatic bolt tightening device. Background technique [0002] Bolts are the most commonly used connecting components in the mechanical field and are widely used in all walks of life. The bolt mainly relies on the connection between its external thread and the threaded hole on the workpiece or the threaded hole of the nut. Therefore, when installing the bolt, it is necessary to turn the bolt several times to screw it into the threaded hole. However, in actual production and life, many bolts are installed in relatively hidden parts, and it is difficult for operators to go deep into these parts to disassemble and assemble the bolts. Therefore, the external structure of the equipment can only be removed or the equipment can be turned over as a whole. The disassembly and assembly of the bolts is time-consuming and labor-intensive, which greatly reduces the wor...
