Chain assembly machine for U-shaped external single-joint agricultural machinery

Abstract

The invention mainly discloses a chain assembly machine for U-shaped external single-joint agricultural machinery. The technical scheme is that a rack is included, a crossed base is arranged on a working table of the rack, a pin shaft press-fit mechanism is arranged above the crossed base, a first feeding mechanism for conveying U-shaped external single joints is arranged on one horizontal side ofthe crossed base, a base for conveying a chain out is arranged on the other horizontal side of the crossed base, a positioning and transferring mechanism is arranged on one vertical side of the crossed base and locates the U-shaped external single joints, a second feeding mechanism for conveying internal single joints and pin shafts is arranged on the other vertical side of the crossed base, theinternal single joints and the U-shaped external single joints are matched by the second feeding mechanism, a positioning mechanism is arranged below the working table and corresponds to the pin shaftpress-fit mechanism, and the pin shafts are connected to the U-shaped external single joints and the internal single joints by the positioning mechanism and the pin shaft press-fit mechanism. The chain assembly machine has the advantages of the press-fit speed is ultrahigh, and the degree of automation and the productivity are high.

Description

technical field [0001] The invention relates to the technical field of chain manufacturing and is suitable for automatic agricultural machinery chain manufacturing equipment, in particular to a U-shaped outer single-section agricultural machinery chain assembly machine. Background technique [0002] The assembly process of the existing U-shaped outer single-section agricultural machinery chain is complicated. Usually, the press-fitter first puts the inner single section into the pressing mold, then pushes the outer single section into the pressing mold, and then puts the pin shaft into the pin blanking hole. , and finally start the hydraulic device for press-fitting. After the pin shaft is pressed into place, it is still necessary to manually move the pressed chain forging to a station for the next step of press-fitting. Press-fitting personnel must memorize the number of joints they press-fit to avoid excessive or low-pressure joints. It can be seen that the existing assemb...

[0002] The assembly process of the existing U-shaped outer single-section agricultural machinery chain is complicated. Usually, the press-fitter first puts the inner single section into the pressing mold, then pushes the outer single section into the pressing mold, and then puts the pin shaft into the pin blanking hole. , and finally start the hydraulic device for press-fitting. After the pin shaft is pressed into place, it is still necessary to manually move the pressed chain forging to a station for the next step of press-fitting.

Press-fitting personnel must memorize the number of joints they press-fit to avoid excessive or low-pressure joints. It can be seen that the existing assembly method has too high requirements for press-fitting personnel, and it is easy to take too long Fatigue, slow press-fitting speed, low degree of automation, low production capacity, long processing procedures, high manufacturing costs, etc. Therefore, the use of automated operations to replace manual work is already the only way to go
