Abstract

The invention discloses a large-diameter honing head comprising a honing head body, a cone body, a rise pin, baffle plates, an oilstone holder and sliding pins, wherein the upper end surface and the lower end surface of the honing head body are respectively fixedly provided with a plurality of baffle plates at intervals; the other ends of the plurality of baffle plates positioned on the upper end surface and the lower end surface of the honing head body respectively extend out of the circumferential margins of the upper end surface and the lower end surface of the honing head body; the upper end and the lower end of the oilstone holder are respectively slidably arranged between the side vertical surfaces of two adjacent baffle plates which correspond to the upper end surface and the lower end surface of the honing head body in a positioning way; the sliding pins respectively penetrate through the upper end and the lower end of the oilstone holder in the positioning way; the sliding pins positioned on the upper end and the lower end of the oilstone holder respectively slidably support against the upper surfaces of the two adjacent baffle plates which correspond to the upper end surface and the lower end surface of the honing head body; the center of the honing head body is movably provided with the cone body; the rise pin can freely slide along the axial direction of the cone body; and one end of the rise pin supports against the surface of the cone body, and the other end of the same supports against the side vertical surface of the oilstone holder, which tends to the honing head body. The invention ensures that the larger-diameter honing head is assembled by small-diameter honing head bodies, thereby reducing the difficulty of production and manufacture and ensuring the manufacturing accuracy of the large-diameter honing head.

Description

The major diameter honing head

Technical field

The present invention relates to a kind of honing head, particularly a kind of major diameter honing head.

Background technology

At present, China's plover mill machine is mainly used in the PRECISION HOLE processing of industry parts such as engine manufacturing, hydraulic valve processing, compressor, hole in piece part geometric accuracy height after the processing, working (machining) efficiency height, because the main still honing of small diameter bore (generally below diameter 400mm), the honing head that is used to process compares less, manufacture and design and be easier to, the bistrique accuracy of manufacture can guarantee by process equipment.

Machining mode is adopted in general honing head design, and when honing head body part processing, the oil stone base chute is finished by the process equipment manufacturing, and other mating parts of directly packing into when assembling can use.

And for the diameter honing head of (is 1000mm as diameter) more greatly, because China does not also have this type of plover mill machine, design concept design routinely, can't process in process of production, the every technical indicator of bistrique cannot guarantee that major diameter grinding head body manufacture difficulty is big, and cost is higher.

In the conventional method, oil stone base slides in chute, promptly move on grinding head body, and major diameter grinding head body manufacturing difficulty is higher, and the accuracy of manufacture of major diameter honing head can not get guaranteeing, can't satisfy instructions for use.

Summary of the invention

In order to overcome above-mentioned defective, the invention provides a kind of major diameter honing head, assemble by the minor diameter grinding head body, save cost, reduce and manufacture difficulty, guaranteed the accuracy of manufacture of major diameter honing head.

The present invention for the technical scheme that solves its technical problem and adopt is: a kind of major diameter honing head, comprise grinding head body, cone, pin rises, baffle plate, oil stone base and sliding pin, on the grinding head body, the lower surface is installed with some baffle plates respectively at interval, on the grinding head body, some baffle plate other ends on the lower surface stretch out on the grinding head body respectively, the lower surface circumferential edges, slide and be located between the side elevation of corresponding adjacent two baffle plates in grinding head body upper surface in location, oil stone base upper end, slide and be located between the side elevation of corresponding adjacent two baffle plates in grinding head body lower surface in location, oil stone base lower end, strengthen the processing diameter with this, on the oil stone base, the lower end is located respectively and is equipped with sliding pin, the sliding pin that is positioned at the oil stone base upper end slides and is resisted against the corresponding adjacent two baffle plate upper surfaces of grinding head body upper surface, the sliding pin that is positioned at the oil stone base lower end slides and is resisted against the corresponding adjacent two baffle plate lower surfaces of grinding head body lower surface, oil stone base and grinding head body are coaxial layout, the grinding head body central movable is provided with cone, cone can move freely along the grinding head body axial centre, the pin that rises can axially be free to slide along it and be positioned in the grinding head body, the pin one end conflict cone surface of rising, the pin other end conflict oil stone base that rises relies on the side elevation of grinding head body, the mobile pin that rises that makes by cone is along its axial slip, thereby realize moving of oil stone base, the oil stone base indentation is in two baffle plates before the processing, press down cone during processing, the drive pin that rises outwards moves, make oil stone base stretch out in two baffle plates, thereby the oil stone base of bonding oilstone being fitted in tightly carried out honing processing on the processed hole wall.

Honing head is when work, cone moves downward and drives the pin that rises and outwards move, oil stone base moves outward, sliding pin outwards slides at baffle surface, so just realize that oil stone base is not to slide in the chute of grinding head body but rely on sliding pin to move outside grinding head body, the crudy of grinding head body is easy to guarantee on existing equipment, does not need to strengthen grinding head body and makes the axially movable oil stone base groove of restriction oil stone base more thereon, thereby the reduction difficulty of processing is saved cost.

As a further improvement on the present invention, described baffle plate is fixed on the grinding head body by screw.

Bistrique also is provided with an oil stone base resetting means as a further improvement on the present invention, and described oil stone base resetting means is rounded ring spring, ring spring is positioned above the described oil stone base successively, process finishing like this, when moving on the cone, oil stone base is indentation automatically under the reset force of spring.

The invention has the beneficial effects as follows: the major diameter honing head adopts fabricated construction, baffle plate is anchored on the grinding head body with screw, bigger diameter is become by the minor diameter grinding head body assemble, and reduces and manufactures difficulty, guarantee the accuracy of manufacture of major diameter honing head, saved cost.
