Service HotlineWith the mass production of large-scale equipment, standardization, and the concept of lean production, it has become more and more important to improve the efficiency of the assembly stage. Nowadays, when assembling small equipment, power tools and automatic bolt supply devices are basically popular, but only for M3 and smaller However, large equipment is often fastened with M8 or larger diameter bolts, and it is still in the process of combining manual and air tools. Among them, the pre-installation of the flat and spring washers on the bolts is completely manual operation. When the bolts need to be tightened in large quantities, the shortcomings of low efficiency are particularly obvious, and the flat and spring washers are easy to be scattered when manually assembled, and there are mixed installations of different specifications. Problems such as less installation and missing installation will affect the processing quality.
screw grooving device comprises a workbench, a vibrating plate is arranged on the upper part of the workbench, a conveying device is arranged below a discharge port of the vibrating disc, the slotting device is arranged on one side of the conveying device, and the slotting device is provided with a reciprocating device. When the movement is extended, the cutting wheel can be used for grooving the screws in the conveying device, and the grooving device is also fixedly provided with a fixed wheel for grinding the grooved screws.
The development of a structure with simple production, reasonable structure and stable feeding is of great significance to the field of riveting automation. Technical realization elements: The purpose of this utility model is to overcome the deficiencies in the prior art, and to provide an automatic feeding device for pressure riveting nuts, which has a compact structure and a reasonable design, and can realize the automatic conveying of the pressure riveting nut on the pressure riveting die. Reduce the use of space, improve work efficiency and save labor costs. According to the technical scheme provided by the utility model: the automatic feeding device for riveting nuts, which is characterized in that: it includes an installation bracket, a connecting frame, a flap bracket, a material pushing cylinder, a material pushing block and a flap; the flap bracket is arranged on the installation Below the bracket and attached to the mounting bracket through the connecting bracket.
The cylindrical pin is mainly used for positioning and can also be used for connection. It is fixed in the pin hole by means of interference fit. Cylindrical pins used for positioning are usually not subject to load or a small load, the number is not less than two, distributed in the symmetrical direction of the overall structure of the connected parts, the farther the better, the pin is in each connected part The length is about 1-2 times the minor diameter. Cylindrical pins can also be used as shafts, and a straight shaft can also be used as cylindrical pins or even centering pins. So what's the difference between a shaft and a pin? The shaft can be used to transmit torque, bear bending moment and torque, and the cylindrical pin can be used for positioning, bear extrusion force and shear force. In a sense (such as small equipment), cylindrical pins can also be used as shafts.
The flat screw mainly includes a rotating part and a screw locking part, wherein the rotating part and the screw locking part are respectively flat-shaped structures; At least two sides of the screw lock portion are respectively provided with tooth rows, and the two tooth rows are mutually dislocated, so that the screw lock portion can be locked in a pre-formed screw hole in the workpiece.
