Embodiment Construction

[0012] The sawtooth mandrel 2 is located in the honing head casing 1, the limit screw 3 is fixedly connected with the serrated mandrel 2, the limit screw is slidingly connected with the groove on the honing head casing, the spring 4 is sleeved on the serrated mandrel, and the working surface of the bottom plate 5 is installed in the long groove at the front end of the honing head jacket. The base plate working surface 5 adopts a zigzag structure and is supported by three taper slopes.

[0013] Working principle: After the honing head is assembled, it is installed on the power head of the machine tool. During honing, under the action of the feed mechanism of the machine tool, the sawtooth mandrel moves forward, and the working surface of the base plate expands to grind the workpiece. When in the original position, the sawtooth mandrel pulls the working surface of the bottom plate back to the original state under the active force of the spring.

Abstract

The invention relates to a sawtooth sliding type automatic telescopic honing head, which belongs to the honing head. The sawtooth core rod is located in the honing head casing, the limit screw is fixedly connected with the serrated core rod, the limit screw is slidingly connected with the groove on the honing head casing, the spring is sleeved on the serrated core rod, and the working surface of the bottom plate is installed on the honing head casing In the long groove at the front end, the working surface of the bottom plate adopts a zigzag structure and is supported by three taper slopes. The advantages are: novel structure, long-time grinding, and no drum shape on the working surface. When the feed mechanism of the machine tool returns, the core rod will quickly pull the working surface of the bottom plate back to the original state under the force of the spring, which will not cause scratches or strains on the inner hole of the workpiece.

Description

technical field [0001] The invention belongs to a honing head, which is mainly used in precision hole processing of aviation, spaceflight and military products. Background technique [0002] With the rapid development of science and technology, mechanical products are becoming more and more complex and their precision is getting higher and higher. Honing technology has been widely used in the machinery manufacturing industry. [0003] At present, the honing head used at home and abroad is roughly the same, and its structure is composed of honing head, bottom plate (honing oil stone frame), working surface (honing oil stone bar), tapered core rod, limit screw, rubber ring or extension spring and other parts. The tapered mandrel is installed in the main hole of the honing head, and the working surface of the bottom plate is installed in the groove of the honing head. There are two grooves on the working surface, rubber rings or tension springs are set in the grooves, and th...
