Benefits of technology

The invention is a truing tool that simplifies the process of adjusting the cutting tip of a grinding machine. The tool has a holder that is connected to a yoke through a threaded feeding rod, which allows the holder to move sideways to the grindstone. The feeding rod can be easily operated with knobs. The holder also has a hole for connection to the universal support, which ensures stability and accuracy of the tool. The cutting depth can be adjusted by adjusting the height of the universal support over the grindstone.

Problems solved by technology

It is well known in the art that a grindstone rotating in a grinding machine needs truing every now and then, because its peripheral grinding surface, which should be round and planar, becomes worn and uneven by extensive use.
Another drawback with this tool is that it comprises two separate parts, which may be lost and which makes the mounting on the machine more difficult.

Embodiment Construction

[0014]A rotatable grindstone 1 of a grinding machine has to be trued at intervals in order to be kept fit for its intended purpose of grinding for example woodcarving tools.

[0015]A known truing tool for this purpose is illustrated in FIG. 1. The tool has a U-rod 2 to be slid on a universal support or cylindrical rod 3 attached on the grinding machine in parallel with the rotation axis of the grindstone 1. The U-rod 2 can be attached to the universal support 3 by means of two lock screws 4.

[0016]Also slid onto the universal support 3 between the two arms of the U-rod 2 is a holder 5, which has a through hole for the universal support. At its forward end, the holder is provided with a cutting tip 6, whereas the opposite end can be held against the U-rod 2.

[0017]The cutting tip 6 consists of diamond grains embedded in a copper cylinder. The grains are positioned like “raisins in a cake”. During use, the soft copper will be worn, and the diamond grains will stick out as peaks on the sur...

Abstract

A truing tool for a grindstone (1) is intended for attachment to a universal support (3) in the form of a cylindrical rod of a grinding machine in parallel with the rotation axis of the grindstone. It has—in a holder (12) therefore—a cutting tip (13) for truing engagement with the grindstone. The holder (12) is movably connected to a yoke (10)—to be attached to the universal support (3)—by a feeding rod (14), which is rotatably supported by the yoke (10) and is in engagement with a threaded bore in the holder (12), for its movement in relation to the yoke transversely of the grindstone (1).

Description

TECHNICAL FIELD [0001]The present invention relates to a truing tool for a grindstone, the tool being intended for attachment to a universal support in the form of a cylindrical rod of a grinding machine in parallel with the rotation axis of the grindstone and having—in a holder therefore—a cutting tip for truing engagement with the grindstone.BACKGROUND OF THE INVENTION [0002]It is well known in the art that a grindstone rotating in a grinding machine needs truing every now and then, because its peripheral grinding surface, which should be round and planar, becomes worn and uneven by extensive use.[0003]A presently used truing tool as defined in the first paragraph of the specification provides an acceptable truing result, but the result obtained depends at least partly on manual work of the operator, both with regard to the adjustment before truing and the truing itself.[0004]Another drawback with this tool is that it comprises two separate parts, which may be lost and which makes...
