Technical Field
The invention belongs to the technical field of screw screwing devices, and particularly relates to a novel automatic screw screwing device for a production line.
Background
With the rapid development of science and technology, industrial automation has been accepted by mass production enterprises, and along with high-efficiency production efficiency, an automatic production line has become the development trend of industrial production. The production line cannot avoid links of screwing a large number of screws, the existing required products are complex and changeable, the original automatic screw screwing machine is not suitable for the current production requirements, the screws can only be screwed at fixed positions mechanically in the positions incapable of being automatically positioned, and the small parts of the screw screwing equipment with visual positioning cannot reduce the damage to the screw head caused by the fact that the screw head is impacted on the edge of the screw by the screwing gun head due to the fact that errors are reduced.
Aiming at reducing errors caused by visual positioning and shaking in the moving process, the invention designs the screw screwing device which is additionally provided with floating positioning on the basis of the visual positioning, so that when a screwing gun head is contacted with the plane of a screwing screw, the screw head is automatically aligned through the floating positioning, the accurate positioning of the screw head is realized, and the screw is screwed efficiently and high in quality.
Disclosure of Invention
The invention relates to a novel automatic screw tightening device for a production line, which aims to improve the accuracy of tightening a gun head and throwing in a screw head during automatic tightening, reduce the abrasion of the tightening gun head and improve the production efficiency.
The invention is realized by adopting the following technical scheme: the utility model provides a novel automatic screw device of screwing up of production line, includes arm and tightening clamp, tightening clamp connects on the arm, tightening clamp is including screwing up the rifle, it is including the motor element, the locating component that floats, connecting rod and the rifle head that have the reduction gear to screw up the rifle, the rifle head is connected the one end of connecting rod, the other end of connecting rod floats and sets up in the locating component that floats, the connecting rod with the locating component circumference that floats is spacing, the locating component that floats with the motor element transmission that has the reduction gear is connected.
In the process of working, after the mechanical arm drives the tightening clamp to reach an appointed working position, the motor assembly with the speed reducer on the tightening gun receives a system instruction to drive the floating positioning pin to work, and after the gun head goes deep into a screw hole of a screw, the motor assembly with the speed reducer drives the gun head to rotate through the floating positioning pin and the connecting rod, so that the purpose of tightening the screw is achieved. Because the motor assembly with the speed reducer is connected with the gun head through the floating positioning pin and the connecting rod, and the floating positioning pin is internally provided with the spring structure, the gun head cannot impact the screw head to damage the edge of the screw head due to acting force when the gun head does not enter the screw hole of the screw.
