Abstract

The utility model relates to a grinding wheel finishing device for a grinder, comprising a machine body fixed on the main shaft of the grinding wheel of a grinder The machine body can follow the flexing of the main shaft to synchronously advance and retreat. A traction mechanism, and a slide block which can be controlled by the traction mechanism to move from top to bottom are additionally arranged on the machine body. A driving mechanism is arranged on the slide block, and the driving mechanism can drive a rolling wheel core shaft to rotate. One end of the rolling wheel core shaft is protruded outside the machine body, and a correcting disk is fixed on the rolling wheel core shaft. When the grinding wheel finishing device for a grinder is used, the contact distance or the separate distance of the correcting disk and the outer edge of the grinding wheel can be regulated by the traction mechanism, thereby, the correcting disk can simultaneously carry out finishing to the grinding wheel when the grinding wheel carries out grinding to a workpiece, or can carry out finishing to the grinding wheel after the grinding wheel grinds.

Description

Grinding wheel dressing device for grinder

The utility model relates to a kind of grinding machine, particularly relates to a kind of being attached on the grinding machine, and the wheel dresser that can repair this emery wheel top layer simultaneously under duty at the emery wheel on this grinding machine.

Grinding machine is a kind ofly to make it have the machine-tool of smooth surface in order to grind a workpiece.Because workpiece has uncertain shape, so the emery wheel on the grinding machine also must relative engagement, and its outer rim also is of similar shape, like this can be fully and equably the surface of this workpiece is processed.For keeping the effect of this abrasion wheel grinding moulding, must give suitable finishing to keep its good abradant surface to this emery wheel.

As shown in Figure 1, dresser 10 commonly used comprises a bearing 12, and is located at some the diamond pens 14 on this bearing 12.During use this bearing 12 is placed on the workbench 16 of this grinding machine, and make each 14 with its nib place trimming wheel.

Use this dresser 10 to have following two weak points often:

(1) because the shape of this emery wheel outer rim is identical with the shape on this workpiece surface to be ground, therefore, in case the shape of workpiece and emery wheel is slightly complicated or the angle of required finishing hour, the nib position of pen 14 just is difficult to deep finishing, and repair in the mode of single-point contact at this nib position, therefore causes the wearing and tearing aggravation easily and reduce finishing effect.

(2) because this dresser 10 must place on the Grinder bench 16 to replace the position of this workpiece, the therefore operate as normal program that need end this grinding machine in use getting round to trimming wheel, thereby influences the grinding machine operating efficiency.

Main purpose of the present utility model is to provide a kind of wheel dresser, can repair this emery wheel simultaneously under the emery wheel duty.

A purpose more of the present utility model is to provide a kind of wheel dresser, when it uses on grinding machine position and conflict mutually of workpiece setting position to be processed is set.

The utility model also has a purpose to be to provide a kind of wheel dresser, its with treat that trimming wheel is wire and contacts, thereby can slow down its wearing and tearing and increase the service life.

For realizing aforementioned purpose, the utility model mainly includes:
