Embodiment Construction

[0008] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0009] like figure 1 As shown, it includes a splint 1, a slider 2, a pin shaft 3, an eccentric shaft 4, a spring 5, a telescopic shaft seat 6 and a collet 7.

[0010] The present invention adopts the pin shaft 3 to be fastened on the splint 1 by the bearing assembly 9, the power (motor) transmits the motion to the slider 2 through the eccentric shaft 4, the telescopic shaft seat 6 is installed on the slider 2, and the slider 2 is supported by the splint 1 The bearing assembly 9 etc. are limited to reciprocating swing (the amount of swing displacement is determined by the eccentricity of the eccentric shaft), the two splints 1 are connected by standard bolts, and the telescopic shaft seat 6 is provided with a standard spring 5 and a collet 7 set On telescopic axle seat 6. A whetstone 8 is arranged inside the chuck 7 . The slider 2 is made of new mate...

Abstract

The invention relates to a mechanical component for grinding pins of stainless steel cold-rolled work rolls in the metallurgical industry, in particular to a grinding head device on a work roll refiner. It mainly includes a splint, a slider, a pin shaft, an eccentric shaft, a spring, a telescopic shaft seat and a chuck. The pin shaft is fastened on the splint by means of a bearing assembly, a slider is installed on the eccentric shaft, and the slider is connected to the splint. The splints are connected by bolts, the telescopic shaft seat is installed on the slider, the telescopic shaft seat is provided with a spring, the chuck is set on the telescopic shaft seat; the chuck is provided with oil stone; the eccentric shaft drives the slider and the telescopic shaft The shaft seat and the chuck swing in the horizontal direction, so that the oilstone can finely grind the roll. The invention has a simple, compact and reasonable structure, is stable, reliable and durable, has few faults and high efficiency, and can ensure that the grinding head is not easily worn during work.

Description

technical field [0001] The invention relates to a mechanical component for grinding pins of stainless steel cold-rolled work rolls in the metallurgical industry, in particular to a grinding head device on a work roll refiner. Background technique [0002] Stainless steel is widely used for its corrosion resistance and bright plate surface. After rolling by rolling mill, stainless steel is required to be bright and smooth, so the requirement for the brightness of work rolls is very high. The grinding head device on the roll fine grinder is used on the fine grinder to finely grind the work rolls of the rolling mill. The grinding pins of the work rolls of the rolling mills in the stainless steel cold rolling industry directly affect the surface quality of the steel strips produced by the rolling mills. In the industry, it is generally rough ground by an outer garden, and then polished by a cloth wheel or finely ground by a whetstone. On the oilstone fine grinding machine, the...
