Abstract

The invention relates to an auxiliary screw tightening device, in particular to an auxiliary screw tightening device with a large diameter. The technical problem of the present invention is to provide an auxiliary large diameter screw tightening device that can fully tighten the screw and reduce the friction between the screw and the nut. An auxiliary tightening device for large-diameter screws, including a handle, the handle is used to take the whole device; a mounting plate, the mounting plate is arranged on the top of the handle; The bottom of the mounting plate, the lower part of the mounting column is connected to the lower part of the handle; the driving motor is arranged on one side of the mounting column, and the driving motor is located directly below the mounting plate. The invention achieves the effects of fully tightening the screw and reducing the friction between the screw and the nut. The nut is clamped by the tightening device, and the drive motor drives the tooth plate and the tightening device to continuously rotate clockwise, so that the nut is tightened step by step. Fixtures.

Description

technical field [0001] The invention relates to an auxiliary screw tightening device, in particular to an auxiliary screw tightening device with a large diameter. Background technique [0002] Whether in daily life or in the industrial field, screws are an indispensable tool. At present, in the industrial field, screws are usually used in conjunction with nuts. Workers first pass the screws through the parts of the utensils that need to be fastened. Then the nut is fully tightened by the tightening tool from the other end, so that the utensil parts can be fixed. [0003] Existing screw tightening devices, such as the Chinese patent whose patent notification number is CN109732333A discloses a multi-type screw tightening device, including a base component, a tightening device and a clamping mobile module, wherein the base component includes a base, which is arranged on the base The lower cylinder above the seat, and the upper cylinder rotatably connected with the lower cylind...
