Description

Wheel Dresser

technical field

The utility model relates to a grinding wheel dressing tool. the

Background technique

After the grinder has been used for a period of time, due to the different positions of the wear, the rotating surface of the emery wheel on it is often uneven, and such an emery wheel seriously affects the quality of the sharpening. The general method is to use a diamond grinding wheel pen to manually correct the grinding wheel so that the rotating surface of the grinding wheel returns to a cylindrical surface. But adopting this method to dress the grinding wheel requires high experience and technical requirements for people, and the effect and efficiency are not ideal, and there is still a certain danger during operation, and there is a potential safety hazard. the

Contents of the invention

The purpose of the utility model is to provide a dresser for finishing the grinding wheel quickly and safely. the

In order to achieve the above object, the utility model has taken the following technical solutions:

The grinding wheel dresser is composed of a bracket and a grinding head installed on the bracket; the grinding head is composed of an adjustment seat, a slider, a rocker and a grinding wheel pen; the adjustment seat is fixed on the bracket; the slider is installed on the adjustment seat through a guide post on; the rocker is also installed on the adjustment seat, and can rotate relative to the adjustment seat; the rotating shaft with external thread on the rocker passes through the screw hole on the slider; the grinding wheel pen is connected to the slider by threads. the

The working principle of the utility model is as follows: install the bracket on the grinder or the grinder base, make the central axis of the guide column on the adjustment seat parallel to the central axis of the grinding wheel, and turn the handle to drive the slider to move on the guide column. Adjust the relative position of the grinding wheel pen and the grinding wheel on the central axis of the grinding wheel. In addition, the grinding wheel pen and the slide block are connected by threads, and the relative position of the grinding wheel pen and the grinding wheel in the radial direction of the grinding wheel can be adjusted by turning the grinding wheel pen to change the protruding length of the grinding wheel pen. Thereby, the grinding wheel pen can be accurately positioned at a certain position. When using, first adjust the nib of the grinding wheel pen near the rotating surface of the grinding wheel, rotate the grinding wheel pen so that the pen tip of the grinding wheel pen has a certain cutting depth relative to the grinding wheel, turn on the power of the grinder machine, and slowly turn the handle to make the grinding wheel pen in the The rotating surface of the grinding wheel moves slowly. When the grinding wheel pen passes through the width of the rotating surface of the grinding wheel, the rotating surface of the grinding wheel is polished into a cylindrical surface to achieve the purpose of dressing the grinding wheel. the

Corresponding to the grinder with double grinding wheels, there can be two sets of grinding heads installed on the bracket. the

The above-mentioned support is preferably installed on a connecting shaft, so that the support can rotate relative to the grinder. When dressing is not required, the wheel dresser can be rotated to a non-occupied position. the

The above-mentioned grinding wheel pen is preferably provided with a knob so as to facilitate the rotation and adjustment of the grinding wheel pen. the

The utility model has simple and safe operation, not only guarantees the quality but also improves the efficiency. It has a positive effect on schools and enterprises to improve production efficiency and production quality. the
