Honing device for polishing inner circumferential wall of metal pipe

Abstract

The invention discloses a honing machine for grinding the inner peripheral wall of a metal pipe fitting, which comprises a honing body and a plurality of pads, a plurality of transition holes are opened on both sides of the honing body, and an adjusting pin is fixed on one side of the pad, and the adjustment The pin is matched with the transition hole, and a fixed seat is installed on the other side of the pad. Blind holes are respectively provided on the two side walls of the groove. The main body of the horizontal part of the oilstone is placed in the groove and the two ends of the horizontal part Placed in the blind hole, a rubber strip is set between the blind hole and the horizontal part of the oil stone; an adjusting rod is installed slidingly 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 set There is an inclined surface matched with the outer circular surface of the 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 a honing machine, in particular to a honing machine for grinding the inner peripheral wall of a metal pipe fitting. Background technique [0002] Honing is a cutting technology with broad prospects. It is not only a processing method that can improve surface roughness, but also a semi-finishing and Finishing process method. Honing does not require special conditions to enable parts to obtain precise dimensions, geometric accuracy, military and engineering machinery and other manufacturing industries. [0003] Honing processing belongs to finishing processing, which can obtain higher processing accuracy than general mechanical processing. It is characterized by the use of high-quality particulate abrasives made of consolidated abrasive oilstone. The particles can ensure a high level of processing accuracy, requiring abrasive particle size, mold Good consistency of hardness and structure requires high accuracy of mold size and ...

Problems solved by technology

Aiming at the deficiencies in the prior art, the present invention makes some improvements to the existing honing machine for grinding the inner peripheral wall of metal pipe fittings, so as to solve the problem of ensuring the running state between the oilstone and the base after the roughness of the inner surface of the workpiece disappears. Keep stable to prevent relative displacement between the two, so as 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 standard, the distance between the oilstone and the inner wall of the workpiece increases at this time, 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 is directly connected with the adjustment rod. The inclined surfaces on the movable end of the pin cooperate with each other, so that the adjusting pin moves outward along the radial direction of the honing body, so as 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;
