Abstract

The invention relates to a device for automatically tightening nuts of a connecting box. A first locating plate, a second locating plate and a motor are vertically fixed to a base. The first locating plate and the second locating plate are provided with two sets of first notches and second notches. A cable shaft for allowing a cable to be placed on is erected between each set of first notch and second notch, and the cable shaft can rotate relative to the first notch and the second notch. A cable shaft gear is arranged on the external diameter of each cable shaft in the circumferential direction. An output shaft of the motor penetrates through the first locating plate and is connected with the cable shaft gears through transmission gears. The transmission gears comprise the a first gear and the second gear, and the first gear and the second gear are axially arranged side by side. The first gear is connected with the output shaft of the motor, and the second gear is meshed with the cable shaft gears. One side of the first gear is provided with more than one ball screw. The second gear is provided with a concave pit. The ball screw can slide into the concave pit or retract out of the concave pit. The device special for automatically tightening the nuts of the connecting box improves the installation efficiency and reduces the defective rate.

Description

(1) Technical field [0001] The invention relates to an installation auxiliary device of a photovoltaic junction box. (2) Background technology [0002] The photovoltaic junction box is connected with cables, and the cables need to be locked by nuts. In the prior art, the nuts are locked manually. However, due to individual differences, the nuts may be too tight or too loose, which will affect the The quality of the junction box, and the manual operation is inefficient, and the rate of defective products is high if it is too tight or too loose. (3) Contents of the invention [0003] In order to overcome the shortcomings of low efficiency and high defective rate of manual operation in the prior art, the present invention provides an automatic nut tightening device with high efficiency and reliable operation. [0004] The technical scheme that the present invention solves its technical problem is: [0005] An automatic nut tightening device for a junction box, comprising a ...
