Pipe joint outer end face moving and finishing device and method

Abstract

The invention relates to the field of pipe joint machining, in particular to a pipe joint outer end face moving and finishing device and method. The device comprises a pipe joint moving mechanism andan outer end face finishing mechanism. The pipe joint moving mechanism and the outer end face finishing mechanism are both fixed to a workbench. The output end of the pipe joint moving mechanism is connected with the input ends of a feeding device, an inner hole finishing device and the outer end face finishing mechanism. The output end of the outer end face finishing mechanism is connected with adischarging port. The pipe joint moving mechanism is used for moving and conveying pipe joints; the outer end surface finishing mechanism is used for deburring the bottom surfaces of the pipe jointsand pipe joint threads; according to the device, by arranging the pipe joint moving mechanism, the moving time of the pipe joints is shortened, and rapid moving of the pipe joints is guaranteed; and the outer end face finishing mechanism is arranged to prevent the pipe joints from deforming, and the machining quality of the pipe joints is improved.

Description

technical field [0001] The invention relates to the field of pipe joint processing, in particular to a device and method for moving and finishing the outer end surface of a pipe joint. Background technique [0002] The pipe joint is a part in the hydraulic system that connects the pipeline or installs the pipeline on the hydraulic component. It is a connection tool between the pipeline and the pipeline, and it is a detachable connection point between the component and the pipeline. The pipe joint plays an indispensable role in the pipe fittings, and it is one of the main components of the hydraulic pipeline. However, in the process of cutting, casting or die forging of pipe joints, some small plastic deformations will occur in the pipe joints, resulting in debris and extremely fine microscopic metal particles in the inner hole and outer end surface of the pipe joints. These are called burrs. The appearance of burrs will not only affect the smoothness of the threaded connec...

AI Technical Summary

Problems solved by technology

[0004] The prior art has the following deficiencies: 1. When moving the pipe joints, a motor is used to drive a moving head to move the pipe joints of different stations to the next station according to the processing sequence; while processing the pipe joints generally requires multiple processing stations, and the distance between multiple processing stations is relatively long; when there is only one transfer head to move the pipe joint, the transfer head needs to move back and forth for a long distance; and when the pipe joint processing is completed, the transfer head needs to move from the processing The end of the station moves to the initial processing station for a longer distance to move again; thus making the moving time longer when moving the pipe joint, which is not conducive to the rapid removal of the pipe joint

2. When removing the burr from the thread of the pipe joint, first use the air claw hand to clamp the tapered part of the outer ring of the pipe joint and drive the pipe joint to rotate, and then the edge trimming element moves in contact with the thread of the pipe joint to remove the burr of the pipe joint thread; while the pipe The joint is of hollow structure and the wall thickness is relatively thin. When the pipe joint is subjected to radial force, it is easy to deform due to the low radial compressive strength of the hollow structure inside; Larger clamping force, when the larger clamping force of the air gripper acts on the tapered part of the pipe joint, that is, the greater clamping force of the air gripper acts on the pipe joint radially along the pipe joint; thus making the pipe The joint is easily deformed during the process of removing thread burrs, which reduces the processing quality of the pipe joint
