Polishing device for inner circumferential wall of drainage pipeline

Abstract

The invention discloses a polishing device for the inner peripheral wall of a drainage pipe, which includes a honing body and a plurality of pads, a plurality of transition holes are opened on both sides of the honing body, an adjusting pin is fixed on one side of the pad, and an adjusting pin is fixed on the other side of the pad A fixed seat is installed on one side, and a groove is opened on the fixed seat. Blind holes are respectively arranged on the two side walls of the groove. The main body of the horizontal part of the oilstone is placed in the groove and both ends of the horizontal part are placed in the blind holes. Inside, 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 an inclined surface matching the protrusion is provided on the movable end of the adjusting pin, and a smooth circular surface and a cone are arranged on the protrusion. surface, and a transitional circular surface is provided at the junction of the smooth circular surface and the conical surface. 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 prevent the oil stone from being damaged. Purpose.

Description

technical field [0001] The invention relates to the field of building profile processing, in particular to a polishing device for the inner peripheral wall of a drainage pipe. 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. But in the existing vertical honing machine, when the roughness of the inner surface of the workpiece on the honing head is reduced to the minimum level, the contact area between the honing stone on the honing head and the inner wall of the workpiece is reduced, so that multiple oil 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 suddenly loses the resistance of ...

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 Relative displacement occurs to achieve the purpose of prolonging the service life of the device; when the invention works, the whetstone is placed in the workpiece, and the honing body is driven 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 In standard mode, when the distance between the whetstone and the inner wall of the workpiece increases, the adjustment rod located in the middle of the honing body starts to be driven, and the adjustment rod moves down until the protruding conical surface directly cooperates with the inclined surface on the movable end of the adjustment pin, making the adjustment The 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;
