Building drainage pipe fitting inner circumferential wall honing treatment structure

Abstract

The invention discloses a building drainage pipe fitting inner circumferential wall honing treatment structure. The building drainage pipe fitting inner circumferential wall honing treatment structurecomprises a honing body and a plurality of cushion blocks. A plurality of transition holes are formed in the two sides of the honing body. Adjusting pins are fixed to one sides of the cushion blocksand are in clearance fit with the transition holes. A fixing base is arranged on the other sides of the cushion blocks. Blind holes are formed in the two side walls of a groove correspondingly. A horizontal part body of oilstone is arranged in the groove, the two ends of a horizontal part of the oilstone are located in the blind holes, and rubber strips are arranged between the blind holes and thehorizontal part of the oilstone. An adjusting rod is arranged in the honing body in a sliding manner and provided with a plurality of conical protrusions. The movable ends of the adjusting pins are provided with inclination faces matched with outer circle faces of the conical protrusions. The mutual impacts between the oilstone and the fixing base are relieved through deformation or deformation recovery of the rubber strips in the running process, accordingly relative displacement between the fixing base and the oilstone is prevented, running synchronism of the fixing base and the oilstone isguaranteed, and the purpose of preventing oilstone damage is finally achieved.

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;
