Building drainage pipe fitting inner circumferential wall honing treatment structure

Abstract

The invention discloses a honing treatment structure for the inner circumferential wall of a building drainage pipe fitting. Cooperate with the transition hole, a fixed seat is installed on the other side of the pad, blind holes are respectively set on the two side walls of the groove, the main body of the horizontal part of the oil stone is placed in the groove and the two ends of the horizontal part are placed In the blind hole, a rubber strip is set between the blind hole and the horizontal part of the oilstone; an adjusting rod is slid inside the honing body, and a plurality of conical protrusions are installed on the adjusting rod, and the movable end of the adjusting pin is provided with a An inclined surface that matches the outer circular surface of a conical protrusion. The invention slows down the mutual impact between the oil stone and the fixed seat through the deformation or recovery deformation of the rubber strip during operation, so as to prevent the relative displacement between the fixed seat and the oil stone, ensure the synchronization of the two operations, and finally achieve the prevention of oil stone damage purpose.

Description

technical field [0001] The invention relates to the field of building material processing, in particular to a honing treatment structure for the inner circumferential wall of a building drainage pipe fitting. Background technique [0002] The metal drainage pipe is the main component of the building drainage system, and its liquid circulation efficiency directly affects the discharge efficiency of the drainage system. For this, it is necessary to polish the inner wall of the drainage pipe before leaving the factory. type honing machine. However, in the existing vertical honing machine, when the roughness of the inner surface of the honing head is reduced to the minimum level, the contact area between the honing stones of the honing head and the inner wall of the workpiece is reduced, so that a plurality of honing stones on the honing head appear idling. Phenomenon, before the distance between the honing stone and the inner wall of the workpiece is adjusted, the whetstone su...

AI Technical Summary

Problems solved by technology

Aiming at the deficiencies in the prior art, the present invention makes certain improvements to the existing honing head to solve the problem of ensuring that the operating state between the oil stone and the base remains stable after the roughness of the inner surface of the workpiece disappears, and preventing the occurrence of Relative displacement, in order to achieve the purpose of prolonging the service life of the device; when the invention works, put the whetstone in the workpiece, and drive the honing body at the same time to realize the honing process of the whetstone on the inner wall of the workpiece, when the roughness of the inner wall of the workpiece is reduced to the processing standard At this time, the distance between the oil stone and the inner wall of the workpiece increases, that is, the adjustment rod located in the middle of the honing body starts to be driven, and the adjustment rod moves down until the outer circular surface of the conical protrusion directly cooperates with the inclined surface on the movable end of the adjustment pin , so that the adjusting pin moves outward along the radial direction of the honing body to realize the gap between the oil stone and the inner wall of the workpiece, and finally realize the fine honing of the inner wall of the workpiece;
