The spring feeding mechanism of the valve core automatic assembly machine

Abstract

The invention discloses a spring feeding mechanism of an automatic valve element assembling machine. The spring feeding mechanism comprises a spring vibrating disk which is mounted on a spring vibrating disk rack, the spring vibrating disk is connected to the upper ends of four slotting type spring feeding pipes through a spring conveying hose, and the four slotting type spring feeding pipes are mounted on a spring feeding pipe mounting plate side by side. The spring feeding pipe mounting plate is fixed at the upper ends of two spring feeding pipe mounting columns which are vertically mounted, and the lower ends of the spring feeding pipe mounting columns are both fixed on a spring feeding pipe mounting column lower plate. A spring distributing cylinder mounting plate is vertically mounted on the front side edge of the spring feeding pipe mounting plate, the upper side and the lower side of the front face of the spring distributing cylinder mounting plate are each provided with four spring distributing cylinders which are mounted side by side, piston rods of the spring distributing cylinders are all provided with spring distributing needles, and the spring distributing needles are all inserted into tiny slots of the slotting type spring feeding pipes. By the adoption of the mode, springs can be quickly conveyed to the specified positions.

Description

technical field [0001] The invention relates to the field of automation, in particular to a spring feeding mechanism of a valve core automatic assembly machine. Background technique [0002] The spool of the expansion valve is an important part of the expansion valve. The spool of the expansion valve is composed of a spring, a spring positioning sleeve, an upper cap head, and a thimble of the valve core. Because of the small amount of use, the process used was manual one by one. Assembled, unified pressing after the assembly is completed, and there is no single-step inspection process in the assembly process. After the pressing is completed, the workers simply test the movement of the valve core and it is over. The service life of such a valve core is very low. Sometimes it is just installed on the valve. There are phenomena such as being stuck and not moving on the computer, which cannot meet the requirements of use at all. Contents of the invention [0003] The technica...
