Embodiment 1

[0023] Such as figure 1 As shown, a low-resistance electric screwing machine of the present invention includes a quick-opening and closing fixing sleeve 1 and a quick-opening and closing clamp 2, and the quick-opening and closing fixing sleeve 1 and the quick-opening and closing clamp 2 are composed of two semi-circular columns It is composed of hinged connection, and the inner wall of each semi-circular column of the quick-opening and closing fixing sleeve 1 is protruded with two semi-circular friction ribs 3, and when the quick-opening and closing fixing sleeve 1 is in a closed state, the four semi-circular friction ribs 3 The friction ribs 3 just constitute two complete friction ribs 3 that surround the inner wall of the fast opening and closing fixing sleeve 1 in the circumferential direction, and the friction ribs 3 are integrally arranged on the inner wall of the quick opening and closing fixing sleeve 1 by welding.

Embodiment 2

[0025] Such as figure 1 and figure 2 As shown, further improvement on the basis of Example 1, the present invention provides a low-resistance electric threading machine, the two ends of the radial opening of the semi-circular column of the quick-opening and closing fixing sleeve 1 are respectively provided with two second A chute 4, the two first chute 4 are located on a straight line in the axial direction of the semicircular column, the long axis extension direction of the first chute 4 is parallel to the axial direction of the semicircular column, and The length of the major axis of the first sliding groove 4 is less than half of the length of the semicircular column; the radial ends of the friction ribs 3 are provided with sliders 5 matching the first sliding groove 4 . The two ends of the radial opening of the semi-circular column are provided with threaded holes vertically interlaced with the first chute 4 . The friction rib 3 moves along the first chute 4 through the...

Embodiment 3

[0028] Further improvement on the basis of Example 2, the present invention provides a low-resistance electric threading machine, the outer wall of the quick opening and closing fixture 2 is protruded along the circumferential direction with two rings of friction rings that match the friction ribs 3 Groove 9.

Abstract

The invention discloses a low resistance electric screw spinning machine, which comprises a fast opening and closing fixing sleeve and a fast opening and closing clamp. The fast opening and closing fixing sleeve and the fast opening and closing clamp are connected by two semicircle ring columns in hinge. Two semicircular annular friction bars are arranged on the inner wall of each semicircle ring column of the fast opening and closing fixing sleeve. The automatic screw spinning machine can reduce friction resistance, wear loss and noise, and improve screw spinning efficiency.

Description

technical field [0001] The invention relates to a screwing tool, in particular to a low-resistance electric screwing machine. 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 threading the lengthened steel bar is generally manual twisting, which is inefficient and labor-intensive; an electric screwing machine is also used, and the patent CN204262716U announces an electric screwing machine, which is driven by a motor through the driving gear and from the The moving gear drives the quick opening and closing fixture to rotate in the quick opening and closing fixing sleeve in turn. The quick opening and closing fixing sleeve has the functions of fixing, supporting and protecting the quick opening and c...
