Description

On-line grinding wheel dressing tooling

technical field

The utility model relates to an on-line grinding wheel dressing tool for a cylindrical grinding machine.

Background technique

After a period of use, the grinding wheel of the cylindrical grinder will passivate and lose its grinding ability or lose its correct geometric shape. After the grinding wheel is blunted, if it is not trimmed in time, the grinding wheel and the parts will slip, and the grinding efficiency will be remarkable. As the grinding force decreases, the grinding force will increase, which will lead to increased deformation of the parts and reduced grinding accuracy. At the same time, vibration and noise will easily occur, which will increase the surface roughness value and cause defects such as straight waves; The grinding heat will increase, which will easily cause surface burns and fine cracks on the parts. For this reason, whether the abrasive grains on the working surface of the grinding wheel are sharp and whether the contour shape is distorted has a direct impact on the grinding efficiency and the surface quality of the processed parts. It can be said that timely and correct dressing of the grinding wheel to shape the grinding wheel or remove the blunt surface to restore the cutting performance and correct geometric shape of the working surface is an indispensable factor to improve the grinding efficiency and ensure the grinding quality. links.

See Figure 1: The grinding wheel dressing tool of a traditional cylindrical grinder includes a fixed seat, a mounting bracket and a diamond pen. The fixed seat is composed of a tensioning block, a tensioning screw and an irregular trapezoidal frame. The tensioning block and the irregular trapezoidal frame are Integral casting, the top surface of the ladder frame is flat, the installation bracket is assembled on the top surface of the ladder frame, and the diamond pen is fixed on the installation bracket. Since the diamond pen is fixed on the top surface of the fixed seat, the height of the entire dressing tool is relatively high. During the process of dressing the grinding wheel, the tooling interferes with the position of the grinding parts, and the machine tool must be in the state where no parts are installed to adjust the grinding wheel. For trimming, the parts have to be disassembled repeatedly during the grinding process, which greatly reduces the grinding efficiency of the parts and increases the labor intensity of the workers; in addition, the fixing seat of the trimming tool is difficult to manufacture and the production cost is high due to its complex structure. advanced defects.

Contents of the invention

The purpose of this utility model is to provide a simple structure, convenient manufacture, low production cost and can perform on-line dressing of the grinding wheel of the external cylindrical grinding machine without dismantling the parts.

The technical purpose of the utility model is achieved through the following technical solutions: an online grinding wheel dressing tool, including a fixed seat, a mounting bracket and a diamond pen, and the diamond pen is axially assembled on the mounting bracket, and the mounting bracket is assembled on the fixing seat opposite to the the end face of the grinding wheel.

The fixing seat is made of a tensioning block, a tensioning screw and a tripod, and the tripod is composed of an upper connecting plate, a lower connecting plate and an installation body. One end of the two connecting plates is respectively connected to the tensioning block, and the other end is connected to the installation body The upper and lower ends are connected, and the angle between the upper connecting plate and the installation body is ≥90°; the installation bracket is vertically assembled on the installation body.

The included angle between the upper connecting plate and the installation body is 90-110°.

A T-shaped chute is provided on the surface of the installation body where the installation bracket is assembled, and the installation bracket is assembled on the installation body through a slider matching the T-shaped chute.

The slider of the installation bracket is positioned on the installation body through set screws.

The axial direction of the mounting bracket is provided with a chute, and the diamond pen is assembled on the mounting bracket through a pin matching the chute.

A nut is arranged on the tension screw rod.

The beneficial effects of the utility model are: the tooling with the above structure assembles the diamond pen on the end face of the fixing seat facing the grinding wheel, which effectively reduces the overall height of the tooling, and avoids the tooling being in the same position as the grinding parts in the process of dressing the grinding wheel. Interference, the grinding wheel of the external cylindrical grinder can be trimmed online without disassembling the parts, which improves the grinding efficiency of the parts and reduces the labor intensity of the workers; in addition, on the premise of ensuring the strength of the fixing seat, the fixing seat is simplified The structure reduces manufacturing difficulty and production cost.

The utility model has the characteristics of reasonable design, simple structure, convenient manufacture, low production cost, stability and reliability, long service life and strong practicability.
