Description

Technical Field

[0001] The utility model relates to the technical field of CBN grinding disc production tools, in particular to a grinding surface partitioning tool for a CBN grinding disc. Background Art

[0002] The CBN grinding disc is composed of a steel substrate and a CBN grinding block bonded to the surface of the steel substrate. In order to facilitate the pressing and forming of the CBN grinding block and to facilitate the replacement of the CBN grinding block in case of damage in the later stage, the CBN grinding block is usually divided into multiple sheet units for production and then evenly bonded to the surface of the steel substrate. This production method can also facilitate the control of the generation and size of the chip groove on the CBN grinding disc, thereby obtaining a high-quality product that is easy to process, maintain and has a good grinding effect.

[0003] Based on the processing method of the above-mentioned CBN grinding disc, the position distribution of the sheet CBN grinding block on the steel substrate is the key to controlling product quality. Usually, workers use a scale and an oil pen to mark a number of corresponding installation areas on the surface of the steel substrate according to the number of CBN grinding blocks required on each steel substrate. However, this partitioning method requires one hand to hold the scale and the other hand to hold the pen, which is inconvenient to operate and difficult to stabilize the scale, affecting the partitioning accuracy.

[0007] A further technical solution is that the upper surface of the disc base is provided with scale marks.

[0008] A further technical solution is that a pointer matching the scale mark is arranged on the rebound column.

[0009] A further technical solution is: a spring is arranged in the mounting hole of the rebound column.

[0010] A further technical solution is: a limit block is arranged on the rebound column.

[0011] A further technical solution is: the imprinter includes a column, a horizontal plate and an imprint strip, the column is adapted to the mounting hole, at least one imprint strip is mounted on the bottom surface of the horizontal plate, and the imprint strip is connected to the ink storage cavity of the horizontal plate.

[0012] A further technical solution is: a sponge is arranged in the ink storage cavity.

[0013] A further technical solution is: a handle is provided on the transverse plate.

[0014] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0015] The utility model provides a grinding surface partitioning tool for a CBN grinding disc. The partitioning tool can avoid the problems of difficult operation and low precision caused by measuring rulers and marking lines. With the help of an impression device, impressions are directly made on the CBN grinding disc substrate according to the required number of partitions, and the angle or position is set. The operation can be completed with one hand, which is simple and fast, greatly improving the work efficiency and ensuring the partitioning precision of the CBN grinding disc.
