Although the sharpening angle of this technical solution can be adjusted automatically, it is also carried out by the adjustment personnel inputting the angle parameters into the control system, and the determination of the angle parameters requires the adjustment personnel's rich adjustment experience to determine
Due to the influence of factors such as supply channels, processing technology, and batches of cutting knives on the market, the angle of cutting knives varies greatly, especially the problem of supply channels and batches.
This greatly increases the difficulty of adjusting the sharpening system, reduces the customer experience, and greatly affects the cutting quality
The existing method of adjusting personnel with rich experience has the problem of low adjustment efficiency and low accuracy

Embodiment 1
[0058] Such as figure 1 with 4 As shown, this method for detecting the angle of the cutting knife on the cutting machine includes steps:
[0059] S1. Establish a rectangular coordinate system, define one of the cross-sections of the cutter as a reference plane, the mechanical center point on the reference plane is the coordinate origin 0, the direction parallel to the two side walls of the back of the knife is the X axis, and perpendicular to the two sides of the back of the knife The direction of is the Y axis;
[0060] Specifically, the mechanical center point is the center of gravity. When the cutter rotates, the centerline of its rotation is the centerline around which the entire cutter rotates. The mechanical center point of each cross-section forms the above-mentioned centerline. The cutting knife includes a blade and a blade back. The blade back has two side walls parallel and equal in thickness. The blade is used for cutting and includes two blade surfaces with a cer...
Embodiment 2
[0078] Such as figure 2 As shown, this system is used for the cutter angle detection system on the cutting machine, including the following modules:
[0079] Establish a Cartesian coordinate system module, which is used to define one of the cross-sections of the cutter as the reference plane, the mechanical center point on the reference plane is the coordinate origin 0, the direction parallel to the two sides of the back of the knife is the X axis, and the direction parallel to the two sides of the back of the knife is the X axis. The vertical direction is the Y axis;
[0080] The module for calculating the cutter angle is used to define the connection points of the blade and the back of the blade in the above reference plane as point a and point c respectively, and the sharp corner point of the blade is point b, and calculate the coordinate value of point a, the coordinate value of point b and c respectively Point coordinate value; Calculate the angle α between the ab strai...
Embodiment 3
[0099] A computer-storable medium, on which computer instructions are stored, and when the computer instructions run, the steps of the method for detecting the angle of a cutting knife on a cutting machine in the first embodiment above are executed.

Abstract
The invention provides a cutter angle detection method and system for a cutting bed, and belongs to the technical field of cutting bed detection. The cutter angle detection method and system solve theproblems that the inclination angle of the edge surface of an existing cutter is difficult to detect, so that the angle of a grinding wheel of a cutter grinding system is adjusted according to humanexperience, the operation is troublesome, and the adjusting precision is low. The cutter angle detection method comprises the following steps of establishing a rectangular coordinate system, wherein amechanical center point is adopted as the origin 0 point of the coordinate system, the direction parallel to the two side walls of a cutter back is adopted as the axis X, and the direction perpendicular to the two side walls of the cutter back is adopted as the axis Y; calculating the angle of a cutter, wherein the connecting points of a cutting edge and the cutter back are a point a and a pointc correspondingly, and the sharp corner point of the cutter edge is a point b; working out the coordinate values of the point a, point b and point c respectively; and working out the left angle and right angle of the cutter edge of the cutter according to the coordinate values of the point a, point b and point c. The cutter angle detection method has the advantages that intelligent detection is achieved, values of the left angle and right angle of the cutter edge of the cutter are worked out, and therefore the grinding angle of the grinding wheel is intelligently adjusted, operation can be conveniently carried out, and the precision is high.
Description
technical field [0001] The invention belongs to the technical field of cutting bed detection, and relates to a method and system for detecting the angle of a cutting knife on a cutting bed. Background technique [0002] With the continuous development of the garment industry, the increasing complexity of the process, and the continuous improvement of quality requirements, the garment industry is increasingly inclined to introduce the cutting bed system as an important means to improve product quality, and the application of the cutting bed is becoming more and more popular. [0003] The cutting bed mainly includes a cutting table, a knife seat, a knife holder, an operation panel and a vacuum suction device. As a large-scale machine tool in garment machinery, the cutting machine mainly uses vibrating cutters to cut fabrics, and cooperates with an excellent sharpening system. The adjustment of the sharpening system is mainly to adjust the corresponding sharpening angle accord...
