Steel bar connecting machine

Abstract

The invention discloses a steel bar connecting machine which comprises a machine frame body with a working platform. A positioning and clamping base which clamps steel bars at the fixed end and can axially slide is arranged on the working platform. A first bearing pedestal and a second bearing pedestal are arranged on the positioning and clamping base in the axis direction. A driven shaft is arranged between the two bearing pedestals in a connected mode. The driven shaft is provided with a through hole where steel bars at the rotating end can penetrate. The end, close to the positioning and clamping base, of the driven shaft is connected with a three-jaw chuck for clamping the steel bars at the rotating end. The other end of the driven shaft is connected with a driven wheel. The steel bar connecting machine further comprises a driving motor. The driving motor drives a driving wheel to rotate. The driving wheel drives the driven wheel to rotate. The steel bar connecting machine has the advantages that the steel bars and sleeves can be rapidly fastened, the labor intensity of workers can be lowered, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to a steel bar connecting machine for connecting two steel bars with a sleeve. Background technique [0002] In the construction industry, traditional steel bar connections include lap joints, welding, etc., but they cannot meet the needs of the rapid development of the construction industry in terms of connection quality, efficiency or operability. In recent years, the method of connecting steel bars in series by using steel bar connecting sleeves with internal threads has been widely used. For example, a connecting sleeve disclosed in patent CN201915561U, two steel bars are respectively screwed on both ends of the steel bar connecting sleeves, thereby Realize the butt joint of two steel bars along the length direction. However, in the current construction site, the connection between the steel bar and the sleeve is manually completed by the worker with a wrench. The labor intensity is very high. Due to the limitation of the ope...

Problems solved by technology

However, in the current construction site, the connection between the steel bar and the sleeve is manually completed by the worker with a wrench. The labor intensity is very high. Due to the limitation of the operating space, the worker must loosen the wrench to tighten the steel bar after twisting the wrench at a certain angle. Clamping, turning an angle, and then re-clamping the steel bar, twisting the steel bar back and forth in this way, and finally tightening the steel bar and the sleeve, so it is time-consuming and laborious, and the efficiency is extremely low, which increases the labor time of workers, reduces labor efficiency, and increases labor cost
