An automatic threading machine for workpiece assembly

Abstract

The invention discloses a workpiece combination automatic die head threading machine which comprises a frame, a conveying mechanism, a thread rolling mechanism, a workpiece fixing mechanism and a related control mechanism. The conveying mechanism comprises a plate chain strip and a chain strip drive motor. A plurality of stations are arranged on the plate chain strip. The thread rolling mechanism and the workpiece fixing mechanism are oppositely disposed on two sides of the plate chain strip. The thread rolling mechanism comprises a first workpiece threading head and a threading head drive unit. The workpiece fixing mechanism is provided with a workpiece fixing part and a workpiece fixing part drive unit. The side, corresponding to the thread rolling mechanism, of the frame is provided with a first travel switch which is used for detecting whether a to-be-combined workpiece is in place or not. The first travel switch, the chain strip drive motor, the threading head drive unit and the workpiece fixing part drive unit are electrically connected with the related control mechanism. The workpiece combination automatic die head threading machine has the advantages that automatic workpiece threading combination is achieved through mechanical automation, stable and good workpiece combination performance is achieved, and the workpiece combination automatic die head threading machine is high in threading efficiency, time saving, labor saving, low in cost, high in yield and low in rework rate.

Description

technical field [0001] The invention relates to a device for workpiece assembly, in particular to an automatic threading machine for workpiece assembly. Background technique [0002] At present, there are many types of combinations between the two workpieces according to the work performance requirements of the workpieces. One type of workpiece combination is realized by metal wires, such as the valve disc on the indoor fire hydrant and the combination of wires between the valve cover. The outer wall of the bonnet screw and the inner wall of the valve disc are provided with a matching wire groove structure, and a wire hole is opened on the valve disc corresponding to the position of the wire groove structure. When assembling, firstly connect the bonnet screw and the valve disc After fitting, insert the metal wire from the wire hole, and then rotate the valve cover and valve disc appropriately, and the metal wire will be drawn into the wire groove structure to realize the mov...
