Limiting nut feeding and tightening device for producing piston assembly and piston assembly assembling equipment

Abstract

The invention relates to the field of piston assembly assembling, and discloses a limiting nut feeding and tightening device for producing a piston assembly. A limiting nut feeding mechanism comprisesa limiting nut feeding rail, a limiting nut pushing air cylinder, a limiting nut feeding air cylinder, a limiting nut lifting air cylinder and a limiting nut limiting plate; and the limiting nut pushing air cylinder is horizontally installed above the limiting nut feeding rail, the output end of the limiting nut pushing air cylinder is located at the discharging end of the limiting nut feeding rail, a limiting nut feeding air cylinder is horizontally installed on the lower portion of the limiting nut feeding rail, a limiting nut lifting air cylinder is vertically installed at the output end of the limiting nut feeding air cylinder, the limiting nut limiting plate is installed at the output end of the limiting nut lifting air cylinder, the limiting nut pushing air cylinder pushes a limiting nut to the limiting nut limiting plate, and a limiting nut positioning groove is formed in the limiting nut limiting plate. According to the limiting nut feeding and tightening device, the feeding structure is simplified, and the feeding efficiency is improved.

Description

technical field [0001] The invention relates to the field of piston assembly assembly, in particular to a limit nut feeding and tightening device for producing piston assemblies. Background technique [0002] The piston assembly is an important part of the cylinder and oil cylinder motion executive parts, which has a wide range of applications, and its main function is to support the piston to do work. The piston assembly includes a connecting piece, a mandrel, a first stop ring, a piston, a guide sleeve assembly, a second stop ring, a limit nut, a recovery valve and a lock nut; the right end of the mandrel is threaded with the connecting piece, and the mandrel includes A shaft section and a second shaft section, the diameter of the first shaft section is larger than that of the second shaft section, threads are provided at the connection between the first shaft section and the second shaft section, threads are provided at the left end of the second shaft section, and the fi...

AI Technical Summary

Problems solved by technology

[0005] 1. When feeding traditional nuts, other structures are needed to transition between the feeding mechanism and the tightening mechanism to complete the nut feeding, resulting in a complex structure;

[0006] 2. The poor positioning accuracy of the connectors leads to the need for repeated assembly when assembling other components, which reduces production efficiency;

[0007] 3. When the connecting piece and the mandrel are tightened, the mandrel cannot be fixed accurately, and the rotating mechanism cannot be quickly combined with the jig, resulting in low tightening efficiency
