Full-automatic quick tightening mechanism suitable for bolt and nut

Abstract

The invention discloses a full-automatic quick tightening mechanism suitable for a bolt and a nut and relates to the technical field of electric tools. The full-automatic quick tightening mechanism comprises a supporting handle, a nut clamping part and a bolt clamping part. Rotary lifting assemblies are arranged on the front parts of front and back ends of the supporting handle; each rotary lifting assembly comprises a shell, a supporting oil barrel is arranged in the front end of the shell, a supporting column is arranged in the supporting oil barrel, an outer magnetic ring is arranged on theouter side of the supporting oil barrel in a sleeving manner, and a supporting barrel is arranged on the outer side of the outer magnetic ring in a sleeving manner; a first clamping hole is formed inthe middle of the lower end of the nut clamping part, an accommodating hole is also formed in the upper side of the middle of the first clamping hole, and a second clamping hole is formed in the middle of the upper end of the bolt clamping part. The full-automatic quick tightening mechanism has the beneficial effects that the bolt and the nut which are matched with each other can be rotated quickly and reversely by adopting the two symmetrically arranged rotary lifting assemblies, so that the effect of quickly tightening the bolt and the nut is achieved; the full-automatic quick tightening mechanism is convenient and rapid to operate, labor- and operating time-saving and skillful and novel in integral structure, and has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a fully automatic fast tightening mechanism suitable for bolts and nuts. Background technique [0002] Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. According to the way of connection force: divided into ordinary and hinged holes. According to the shape of the head: there are hexagonal head, round head, square head, countersunk head and so on. Among them, the hexagonal head is the most commonly used. Generally, countersunk heads are used where connections are required. Bolt has a lot of call, and everyone call may b...

Problems solved by technology

[0003] At present, in the process of tightening and fixing bolts and nuts, most of them are manually operated. During the operation, one end of the bolt or nut needs to be fixed to facilitate tightening. The operation takes a long time, the tightening effect is poor, and there is a lack of corresponding automatic tightening tools on the market.
