Embodiment 1

[0027] Such as figure 1 As shown, the present invention is an electric threading machine that is easy to control the degree of tightening, including a quick-opening and closing clamp 1 and a quick-opening and closing fixing sleeve 2. The quick-opening and closing clamp 1 is installed on the quick-opening and closing fixing sleeve 2. A first fixing rod 3 and a second fixing rod 4 are welded on a movable side wall of the quick opening and closing fixing sleeve 2, and the axial directions of the first fixing rod 1 and the second fixing rod 2 are both perpendicular to the quick opening and closing fixing sleeve The axis of 2 is vertical. It also includes a rotating shaft 5, the rotating shaft 5 is fixed on the first fixed rod 3 and the second fixed rod 4 through a bearing seat 6, and the axial direction of the rotating shaft 5 is parallel to the axial direction of the quick opening and closing clamp 1. A driving wheel 7 is provided on the rotating shaft 5, and the periphery of the ...

Embodiment 2

[0029] Further improved on the basis of embodiment 1, the present invention provides an electric screwing machine that is easy to control the degree of tightening. The end of the quick opening and clamp 1 is integrated with a stop ring 10, and the driven wheel 8 passes The clearance fit is sleeved on the end of the quick opening and closing jig 1 to abut the limit ring 10; on the driven wheel 8 and on the end surface facing the limit ring 10, two trunnions 11 are protruding, and the trunnions 11 are both provided There is a through hole, the end surface of the limit ring 10 facing the driven wheel (8) is provided with a limit groove adapted to the trunnion 11, and the side wall of the limit ring 10 is provided with a threaded hole. The trunnion 11 is inserted into the limit groove, and the bolt 12 is screwed into the threaded hole and the through hole on the trunnion 11 to fix the driven wheel 8 on the limit ring 10 in turn.

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 threading tool, in particular to an electric threading machine which is easy to control the degree of tightening. 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 large, and a large manpower input is required. At present, the method of using threaded connection to lengthen steel bars is generally manual screwing, which is inefficient and labor-intensive. There is also the use of electric screwing machines. Patent CN204262716U announces an electric screwing machine that uses 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 over tightening or insufficient tightening are prone to occur. Summary of the invention [0003] The technical problem t...
