Honing head

Abstract

The invention discloses a honing head which comprises a honing body and a plurality of cushion blocks, wherein a plurality of transitional holes are formed in both sides of the honing body, adjusting pins are fixed on one side of the cushion blocks, the adjusting pins are in clearance fit with the transitional holes, fixed seats are installed on the other side of the cushion blocks, blind holes are respectively formed in both side walls of grooves, a main body of the horizontal part of an oil stone is arranged in the grooves, both ends of the horizontal part of the oil stone are arranged in the blind holes, and rubber strips are arranged between the blind holes and the horizontal part of the oil stone; an adjusting rod is arranged in the honing body in a sliding mode, a plurality of tapered bulges are installed on the adjusting rod, and inclined surfaces which are matched with the external circular surfaces of the tapered bulges are formed on the free ends of the adjusting pins. According to the honing head, mutual impact between the oil stone and the fixed seats is reduced through deformation or deformation recovery of the rubber strips during operation, so as to prevent relative displacement between the fixed seats and the oil stone, guarantee operation synchronization of the fixed seats and the oil stone, and finally achieve the purpose of preventing the oil stone from being damaged.

Description

technical field [0001] The invention relates to a honing machine, in particular to a honing head. 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 shape, and in order to achieve small cutting and efficient cutting...

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;
