Automatic material discharging mechanism of bush press-in machine

Abstract

The invention discloses an automatic material discharging mechanism of a bush press-in machine. A workpiece placement platform is fixed on a workbench of the automatic material discharging mechanism. Multiple hexagon prisms are fixed on the lower end face of the workbench and fixed on a base plate. A thin air cylinder is fixed on the lower end face of the base plate. A piston rod of the thin air cylinder penetrates through the base plate and is fixed on a lifting supporting frame plate. A linear bearing is fixed on the lifting supporting frame plate. A guide shaft is inserted in the linear bearing in a sleeved mode. The two ends of the guide shaft are fixed on the workbench and the base plate respectively. Two sets of ejector rods are fixed on the upper end face of the lifting supporting frame plate. The top ends of the ejector rods penetrate through the workbench and are fixedly connected with L-shaped material discharging plates. The L-shaped material discharging plates are located on the left and the right of the workpiece placement platform respectively. An air cylinder installation supporting frame is fixed on the workbench on the rear side of the workpiece placement platform. A guide rod air cylinder is fixed on the air cylinder installation supporting frame. By means of the automatic material discharging mechanism of the bush press-in machine, manual material taking below a punching device is not needed, the labor intensity of operators is relieved and meanwhile, the safety accidents of bruising the hands are avoided.

Description

Technical field: [0001] The invention relates to the technical field of press-fitting machines, and more specifically relates to an automatic discharge mechanism of a bushing-pressing machine. Background technique: [0002] The bushing is a ring sleeve that acts as a gasket. It is mainly used in the field of valves. It is generally pressed on the valve cover to protect the valve stem passing through the valve cover and has a good sealing effect. Its hardness is generally smaller than that of the valve stem. When it is worn out, only the bushing needs to be replaced. Compared with the replacement of the valve stem and other parts without the bushing, the cost of only replacing the bushing is much lower. Some existing bushing press-in machines only realize the pressing of the bushing alone, and when taking out the workpiece pressed into the bushing, it can only be taken out by hand. For some relatively bulky workpieces, it is difficult to take out the material by hand , At th...

AI Technical Summary

Problems solved by technology

Some existing bushing press-in machines only realize the pressing of the bushing alone, and when taking out the workpiece pressed into the bushing, it can only be taken out by hand. For some relatively bulky workpieces, it is difficult to take out the material by hand , at the same time, manual retrieving increases the fatigue strength of the operator

Moreover, it is often necessary to put your hands under the stamping equipment when using manual retrieving. When the equipment fails, safety accidents will occur, so there are certain safety hazards in manual retrieving.
