Problems solved by technology

One end of the honing head is connected to the spindle joint of the machine tool, and the rod is embedded or connected to the honing oil stone. Under the action of the feed structure of the machine tool, the honing oil stone is driven to expand radially to realize the cutting feed of the honing, so that the workpiece hole can obtain the required dimensional accuracy. , shape accuracy and surface roughness, the st

Abstract

The invention belongs to the technical field of honing machines, and particularly relates to a three-expansion honing head for a honing machine. The three-expansion honing head comprises a body. An outer expansion rod is arranged in the body, and an inner expansion rod is sleeved with the outer expansion rod. A first expansion core and a second expansion core are fixedly arranged on the outer expansion rod coaxially. The outer expansion rod is coaxially sleeved with an expansion sleeve, and the inner expansion rod is connected with the expansion sleeve. A third expansion core and a fourth expansion core are arranged at the two ends of the expansion sleeve. A bottom cover is arranged at the bottom of the body, and a large spring and a small spring are arranged at the lower ends of the outerexpansion rod and the inner expansion rod. A sand strip seat A, a sand strip seat B and a sand strip seat C are cooperatively arranged on the body. The two ends of the sand strip seat A and the sandstrip seat B are sleeved with first tension springs, and the two ends of the sand strip seat C are sleeved with second tension springs. The three-expansion honing head for the honing machine can complete fine grinding-coarse grinding-fine grinding on the same machine in the same procedure at a time.

Description

technical field [0001] The invention belongs to the technical field of honing machines, and in particular relates to a three-expansion honing head for a honing machine. Background technique [0002] Honing (also known as boring and grinding) is the finishing process of the finished surface of cast iron parts, steel parts, etc. with the oil stone (also called honing bar) embedded in the honing head. The honing machine is a grinding machine that uses a honing head to honing the surface of the workpiece. It is mainly used for honing workpiece holes in manufacturing industries such as automobiles, tractors, hydraulic parts, bearings, and aviation. One end of the honing head is connected to the spindle joint of the machine tool, and the rod is embedded or connected to the honing oil stone. Under the action of the feed structure of the machine tool, the honing oil stone is driven to expand radially to realize the cutting feed of the honing, so that the workpiece hole can obtain th...
