Abstract

The present invention discloses an electric screwing machine with easily controllable tightness. The electric screwing machine comprises a fast-switching fixture and a fast-switching fixing sleeve. The fast-switching fixture is arranged on the fast-switching fixing sleeve, one side face of the fast-switching fixing sleeve is provided with a first fixing rod and a second fixing rod, and the axial directions of the first fixing rod and the second fixing rod are perpendicular to the axial direction of the fast-switching fixing sleeve. The electric screwing machine also comprises a rotary shaft. The rotary shaft is fixed onto the first fixing rod and the second fixing rod via bearing blocks, and the axial direction of the rotary shaft is parallel to the axial direction of the fast-switching fixture; the rotary shaft is provided with a driving wheel, and the outer circumference of the driving wheel is smooth and provided with a convex tooth; one end of the fast-switching fixture along the axial direction is provided with a driven wheel which is matched with the driving wheel; and the end, near the driving wheel, of the rotary shaft is provided with a joint which is connected with an electric wrench. By using intermittent drive and transmission as a power source of the screwing machine, it is easy to control the tightness of a joint between two rebars, thus preventing the joint from damage due to excessive screwing.

Description

technical field [0001] The invention relates to a screwing tool, in particular to an electric screwing machine which is easy to control the tightening degree. Background technique [0002] In the current bridge engineering and housing construction projects, it is necessary to lengthen the steel bar connection to the required size, especially the steel cage production of the bridge pier, the connection workload is heavy, and a large manpower input is required. At present, the method of threaded connection lengthening steel bars is generally manual twisting, which is inefficient and labor-intensive; an electric screwing machine is also used, and the patent CN204262716U announces a kind of electric screwing machine, which is to use a motor to drive the screwing machine to rotate. It is not easy to control the degree of tightening of steel bars, and problems such as excessive tightening or insufficient tightening are prone to occur. Contents of the invention [0003] The tech...
