Problems solved by technology

From the above working mechanism, it can be seen that firstly, the screwdriver needs to screw in the screws one by one, which is inefficient. Secondly, although the circuit is fixed, the program needs to be written according to the position of each bolt in each workpiece. The program is complicated. Finally, after each movement of the manipulator Whether the positioning is accurate or not needs to be judged and fed back by the corresponding sensor electrical components. Although it can be done with the current technology, the cost is high and the structure is complicated.

Abstract

The invention discloses a screw screwing machine. The screw screwing machine comprises a base plate, wherein the base plate is a rectangular metal plate which is arranged in the horizontal direction,four corners of the base plate are provided with optical shafts in a penetrating mode, the tops of the optical shafts are provided with a fixing plate, a separation and reunion assembly is installed between the fixing plate and the base plate, a motor is installed on the top surface of the base plate, and a driving wheel and a driven wheel are arranged on the bottom surface of the base plate. Thescrew screwing machine has the beneficial effects that the position of a screwdriver is matched with a workpiece, only the screwdriver needs to be moved in the vertical direction, the rotation and driving of the screwdriver can be achieved, and the structure is simple, all screws are screwed once, so that the production efficiency is improved, only one motor is needed to screw all screws, the costis further controlled, and the screwing synchronous rate and efficiency are improved.

Description

technical field [0001] The invention relates to the field of assembly machinery, in particular to a screw driving machine. Background technique [0002] In the field of assembly machinery, screwing and bolting are the most commonly used assembly and fixing methods. In the prior art, the working mechanism of the automatic screw-tightening machine is to fix the electric screwdriver on the manipulator, generally a three-axis gantry manipulator, and then design the electric control circuit according to the structure of the electric screwdriver and the manipulator, and then based on the workpiece The position of the screw is written into the program, so that the manipulator controls the screwdriver, and the screws and bolts are screwed in one by one in a programmed manner. From the above working mechanism, it can be seen that firstly, the screwdriver needs to screw in the screws one by one, which is inefficient. Secondly, although the circuit is fixed, the program needs to be wr...
