Nut retaining torsion control device of automatic line box body

Abstract

The invention relates to a nut retaining torsion control device of an automatic line box body, comprising a base, a retaining plate on the base and a slider which can slide relative to the base, wherein both ends of the retaining plate are provided with a gear and a servomotor; the input end of the servomotor is connected with a controller; an output shaft is connected with the center of the gear; both sides of the slider are provided with a jaw and a moving gear which can rotate relative to the slider; the axial direction of the jaw is provided with a mounting hole and a notch; the moving gear and the slider are respectively provided with a notch; the three notches are arranged on the same straight line; the slider is connected with the air cylinder rod of an air cylinder; and the air cylinder and the servomotor are jointly connected with a switch. In the invention, the required torque and speed are output by the servomotor and then are transferred by the gear to automatically tightly screw the nut, and because the output shafts outputs the preset torque and speed, the force of tightly screwing the nut is just right, thereby preventing products from being damaged due to the excessive force and also preventing the products from being screwed unfirmly due to the too small force.

Description

technical field [0001] The invention relates to a torque control device capable of automatically fixing a nut. Background technique [0002] When the nut and the screw are tightened, the applied torque needs to be just right. If the torque is too large, it is easy to damage parts, especially some plastic products. If the torque is too small, it cannot be fully connected and is easy to loosen. In the prior art, there are still many people's feelings to judge whether the screw is in place, which has many differences, and the production efficiency is low. In the prior art, there are also many tools for controlling torque, some of which are limited by mechanical structure to prevent damage to components due to excessive torque, such as the torque of the Chinese utility model patent starting tool with patent number 200820184513.2 on December 30, 2008. The control device includes a control group and an output group. The control group is provided with a drive seat, several balls a...

Problems solved by technology

Although the above-mentioned technologies all produce certain effects, they still need to rely on manpower to achieve tightening, and the torque and speed of nut tightening cannot be uniformly controlled, and these technologies are all aimed at nuts without wires, and for boxes with wires. , such as a solar photovoltaic junction box, its threaded nut is screwed tightly on the box body. Since the nut is threaded, it cannot be tightened with the torque control device of the above structure
