Problems solved by technology

This kind of honing head can only replace the sand bars, and the size of the processed aperture does not change much, and it is impossible to realize large-span aperture processing. Therefore, during the processing, the honing head still needs to be disassembled and assembled, resulting in increased costs.

Embodiment

[0041] A kind of honing head combination device, its structure is as figure 1 As shown, it can process full-circle holes and non-full-round holes in the range of 300mm-1000mm. The combined device is composed of a fine-tuning rod part 1 with a split structure, an expanding mandrel part 2 and a honing sleeve part 3. The fine-tuning rod part 1 is connected to the honing sleeve part 3 through the flange plate 4 and bolts to realize the radial positioning with the honing sleeve part 3. In addition, the axial positioning with the honing sleeve part 3 is realized through the key groove, and the fine-tuning joint is fixed by double positioning. The position between the rod part 1 and the honing sleeve part 3.

[0042] The structure of the honing sleeve part 3 is as follows Figure 2-4 As shown, the honing sleeve part 3 is sleeved on the outside of the expander mandrel part 2. The honing sleeve part 3 includes a sleeve body 35, a grinding bar 31 and a guide plate 32 arranged on the ou...

Abstract

The invention relates to a honing head combination device which can process whole-circle holes and non-whole-circle holes with the diameters ranging from 300mm to 1000mm. The honing head combination device comprises a fine adjustment connection rod part, a pneumatic core shaft part and a honing sleeve part, wherein the fine adjustment connection rod part, the pneumatic core shaft part and the honing sleeve part are of a split type structure, and the fine adjustment connection rod part is connected with the honing sleeve part through a flange plate and a bolt and is located through a key groove. The honing sleeve part is sleeved on the outer side of the pneumatic core shaft part and comprises a sleeve body, a honing strip, a guide board and a regulating bolt, wherein the honing strip and the guide board are arranged on the outer surface of the sleeve body, the regulating bolt is arranged on the lower portion of the honing strip, the pneumatic core shaft part is arranged at the axial center of the honing sleeve part, and the regulating bolt abuts against the pneumatic core shaft part. Compared with prior art, the honing head combination device has the advantages that the split type structure is utilized, using convenience is achieved, manufacturing cost and using cost are greatly lowered, and large-span holes with the diameters ranging from 300mm to 1000mm can be processed.

Description

technical field [0001] The invention relates to a processing device for grinding a large-diameter hole mirror surface, in particular to a honing head assembly device. Background technique [0002] The honing head tool is a special tool for grinding the mirror surface of large-aperture holes. The existing honing head tool can replace the ejector pin when processing the full-circle aperture, and the adjustment range is 50mm. When honing parts with different apertures for the first time, it is necessary to adjust the guide plate and the grinding bar and assemble the grinding bar in the honing head and the outer circle of the guide plate as a whole. The roundness accuracy of cutting holes. More importantly, when the diameter of the grinding hole exceeds its maximum adjustment range, the entire set of honing head tools will be replaced, resulting in a large manufacturing cost. [0003] The Chinese patent application number 200520032271.1 discloses a honing head, which includes ...
