Abstract

The screw automatic tightening device and the screw automatic assembly machine of the present invention, the tightening device includes a mounting seat, a main lifting mechanism, a base, a screwdriver, a screwdriver guide assembly, a nail suction tube assembly and a nail receiving groove assembly, and the main lifting mechanism is arranged on the mounting seat , the base is set at the driving end of the main lifting mechanism, the screwdriver guide assembly includes a clamping piece, a guide column and a linear guide bearing, the screwdriver, the clamping piece and the guide column are connected to form a whole that slides freely up and down relative to the base, and the handle of the screwdriver is clamped On the clamping part, the bit extends downward through the base. The nail suction tube assembly includes a nail suction tube, a telescopic guide and a vacuum generator. The nail suction tube can slide up and down freely relative to the base. The nail receiving slot assembly includes a body , nail slot and nail slot driving mechanism. The automatic assembly machine includes a main frame, a jacking mechanism arranged on the main frame, an XY axis moving mechanism, a nail feeding mechanism, and the above-mentioned automatic screw tightening device. When the screw of the invention is tightened, the impact on the screw thread is small, and the screw can be operated in a narrow space.

Description

technical field [0001] The invention relates to the technical field of assembly of inverter modules in the rail transit industry, in particular to an automatic screw tightening device and an automatic screw assembly machine. Background technique [0002] At present, the assembly and production of converter modules in the rail transit industry is completely dependent on the manual work of workers, and it is difficult to improve production efficiency. One of the technical difficulties in the design and development of the converter module assembly automation production line is the installation of the IGBT screws in the converter module. The converter module IGBT assembly process needs to install 64 screws, and the IGBT screw installation has installation sequence, tightening torque, etc. Process requirements and installation quality directly affect the heat dissipation effect of IGBT, which is the focus of product quality control. At present, there is no ready-made screw automa...
