Description
Technical Field
The invention relates to a device and a method for detecting the abrasion loss of a cutting edge of a full-automatic formed milling cutter, belonging to the field of grinding of band saw blade milling cutters.
Background
The forming milling teeth is a common mode for processing the bimetal band saw blade and the gear at present. The sawtooth forming mode of the band saw blade generally adopts a forming milling cutter to mill teeth. In the use process of the sawtooth forming milling cutter, the cutting edge can generate a wear area with a certain width after being used for a period of time. When the wearing area reaches a certain width, the cutting edge is no longer sharp and the processing quality is influenced, and the wearing area needs to be ground on a special tool grinding machine to obtain a new cutting edge.
Taking the milling of the bimetallic band saw blade as an example, the grinding needs to be performed again when the abrasion width of the cutting edge of the milling cutter reaches about 0.3 mm. At present, the grinding amount of the milling cutter is generally determined by the experience of field operators and by the naked eye or by means of a magnifier, so that on one hand, the grinding amount is roughly determined, and on the other hand, the milling cutter is taken down in the grinding process to be detected to determine whether the grinding requirement is met.
The disadvantages of the prior method are:
1) Time consuming and not highly accurate. Taking a general milling cutter for band saw blade formation as an example, one milling cutter generally has 12 to 16 spiral grooves (i.e. 12 to 16 groups of cutting edges in a circle), and 6 to 18 cutting edges are distributed on each spiral groove according to different products, so the total number of cutting edges involved in cutting may be hundreds or even two to three hundreds, the abrasion loss of each cutting edge is different, and the difference is 0.05 to 0.1mm under general conditions. The abrasion loss (generally about 0.3 mm) cannot be obtained more accurately by using naked eyes or a magnifying glass for detection, and if each cutting edge is detected, the consumed time is very much.
2) The waste is large, and the complete grinding of the cutting edge can not be ensured to be in place. In the existing milling cutter grinding, in order to ensure that the cutting edge can be completely ground, a method of making the grinding modulus larger than the abrasion loss is generally adopted. Taking the cutting edge abrasion loss of 0.3mm as an example, the grinding amount needs to reach about 0.35mm, so that about 16% of the cutting edge is wasted actually.

In order to achieve the purpose, the invention adopts the technical scheme that:
a device for detecting the abrasion loss of the cutting edge of a formed milling cutter comprises the milling cutter which is arranged on a base rotary platform of the milling cutter and can rotate around a self-rotating platform of the milling cutter, and a visual detection module for detecting the abrasion width of the cutting edge of the milling cutter; a Cartesian coordinate system is defined at any position of a visual detection module, wherein the X axis of the Cartesian coordinate system extends along the horizontal direction of the visual detection module, the Y axis extends along the straight line passing through the rotation center of the visual detection module in the vertical direction of the X axis, a detection module X-direction translation table used for driving the visual detection module to move along the X axis direction, a detection module Y-direction translation table used for driving the visual detection module to move along the Y axis direction, a visual detection module rotating table used for driving the visual detection module to horizontally rotate and a laser displacement sensor used for detecting the position of the cutting edge of the milling cutter; preferably, the visual detection module is a CCD camera.
