Technical Field

The utility model relates to a be used for plane grinding to play the effect of repairing to grinding disc surface.

Background

In the process of plane grinding, particularly in the process of grinding the sealing surface of a hard alloy sealing ring, because a radial or spiral chip removal groove is formed on the horizontal grinding surface of a grinding disc on a plane grinding machine, when the sealing ring in an inner hole of a fixing plate in a dressing wheel is ground on the grinding disc, the sharp edge of the chip removal groove and the sharp edge of the outer circumferential edge of the grinding disc often scratch the grinding surface of the sealing ring, and the primary qualified rate after grinding is reduced. The existing grinding machine is generally provided with a plurality of stations for installing the finishing wheels, and due to the existence of sharp-edge burrs, in order to ensure the primary qualified rate, a grinding wheel disk is installed on one station to grind the sharp-edge burrs, the grinding wheel disk is light and hard, and is not suitable for installing products to be ground after punching, so that the stations for installing the grinding wheel disk cannot install the products, and the grinding efficiency of the products is reduced.

SUMMERY OF THE UTILITY MODEL

Based on above problem, the utility model aims to provide a mechanism is maintained with combination to plane grinding.

In order to realize the above purpose, the utility model discloses a technical scheme be: the utility model provides a plane grinds with combination trimming mechanism, includes base cover, emery wheel cover, fixed plate, the base cover is annular steel bushing, the emery wheel cover is established in annular steel bushing bottom in order to form the combination trimming wheel, and the fixed plate sets up in the inner circle of combination trimming wheel, and the hole of fixed plate sets up the product of treating the grinding.

During the use, will make up the trimming wheel and install on the abrasive disc of plane grinder, emery wheel cover and abrasive disc contact, adorn the fixed plate that the hole has the product in the inner circle of making up the trimming wheel, start the plane grinder, the abrasive disc rotates in order to grind the product in the fixed plate hole, the in-process of grinding, the emery wheel cover of making up the trimming wheel plays fine clearance effect to the sharp limit burr of abrasive disc chip groove to reduce sharp limit burr and to the product fish tail, once the qualification rate obtains improving by a wide margin.

Specifically, an aluminum sleeve is arranged between the base sleeve and the grinding wheel sleeve; specifically, the inner wall of the end wall of the bottom of the base sleeve extends axially downwards to form an annular lower convex ring, a lower blind hole with a downward opening is formed in the lower convex ring, a plurality of upper convex rings embedded with the lower convex ring are arranged at the top of the aluminum sleeve, upper blind holes with upward openings are formed in the upper convex ring, the upper blind holes correspond to the lower blind holes in position one by one, and pin shafts are arranged in a group of corresponding upper blind holes and lower blind holes; the aluminum sleeve has the advantages that the upper convex ring and the blind hole are easier to process on the aluminum sleeve than on the grinding wheel sleeve, the lower end of the aluminum sleeve base body is glued and then butted with the grinding wheel sleeve, then the lower end of the aluminum sleeve base body is pressed to be molded, then the aluminum sleeve base body is placed in a high-temperature furnace to be sintered, and finally the upper convex ring and the blind hole are processed on the upper end of the aluminum sleeve; after the grinding wheel sleeves with different granularities are respectively processed and molded with the aluminum sleeve, the aluminum sleeve with the grinding wheel sleeves with different granularities is replaced according to the requirement in the using process.

The grinding wheel sleeve is a resin bond diamond grinding wheel, and the granularity of the diamond grinding wheel is optimized to be the same as that of grinding paste.

The utility model has the advantages that:

the utility model provides a mechanism is maintained with combination to plane grinding adopts base cover and emery wheel cover combination to form the combination to maintain the wheel, and during the use, the emery wheel cover plays fine clearance effect to the sharp limit burr of grinding mill chip groove to reduce sharp limit burr and to the product fish tail, also need not occupy a special emery wheel dish of station installation and clear away sharp limit burr, grind the back and once qualification rate and efficiency obtain improving by a wide margin.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Examples

As shown in fig. 1, the present embodiment provides a combined dressing mechanism for plane grinding, including a base sleeve 1, an aluminum sleeve 4, a grinding wheel sleeve 2, and a fixing plate 3, where the base sleeve 1 is an annular steel sleeve, an inner wall of a bottom end wall of the base sleeve 1 extends axially downward to form an annular lower convex ring, the lower convex ring is provided with a lower blind hole with a downward opening, the top of the aluminum sleeve 4 is provided with a plurality of upper convex rings embedded with the lower convex ring, the upper convex ring is provided with upper blind holes with upward openings, the upper blind holes correspond to the lower blind holes one by one, and a pin 5 is arranged in one group of the corresponding upper blind holes and the lower blind holes; the grinding wheel sleeve 2 is arranged at the bottom of the aluminum sleeve 4 to form a combined dressing wheel, the fixing plate 3 is arranged at the inner ring of the combined dressing wheel, and the inner hole of the fixing plate 3 is provided with a product 8 to be ground; the grinding wheel sleeve 2 used in the present embodiment is a resin bond diamond grinding wheel having the same particle size as the abrasive paste.

When the combined dressing wheel is used, as shown in fig. 2, the combined dressing wheel is placed on a grinding disc 6 of a grinding machine, two baffle rollers on a bracket 7 of the grinding machine are abutted against an outer ring of the combined dressing wheel, a fixing plate 3 is placed on an inner ring of the combined dressing wheel, a product 8 is placed in an inner hole of the fixing plate 3, the grinding machine is started, the grinding disc 6 rotates clockwise, the combined dressing wheel also rotates clockwise under the action of the rotating motion of the grinding disc 6 and the two baffle rollers on the bracket 7, the combined dressing wheel drives the fixing plate 3 to rotate clockwise, and the fixing plate 3 drives a workpiece to rotate clockwise; during the grinding, the diamond grinding wheel sleeve 2 which is in contact with the grinding disc 6 and is combined with the dressing wheel plays a role in dressing sharp-edged burrs on a grinding groove and the outer circumference in the rotating process, so that the sharp-edged burrs are eliminated, and the sealing surface of the sealing ring is scratched by the sharp-edged burrs. The existing grinding machine is generally provided with three stations for installing combined trimming wheels, the number of the combined trimming wheels can be increased or decreased according to the specific number of sharp edge burrs, and the stations without the combined trimming wheels can be selected to adopt integrated steel loose-center wheels; because the aluminum sleeve 4 is detachably connected with the base sleeve 1, the aluminum sleeve 4 with the grinding wheel sleeve 2 with the applicable granularity can be replaced according to actual requirements.

The above embodiments of the present invention are merely examples for illustrating the present invention and are not intended to limit the embodiments of the present invention.
