Problems solved by technology

In order to achieve good quality cutting, it is necessary to ensure that the circular saw blade cuts straight and the saw path is narrow, and this involves the detection of the end jump and flatness of the circular saw blade. The method is to first scrape the circular saw blade with a flat ruler, and the operator judges the flatness value according to the size of the gap formed between the circular saw blade and the flat ruler, and then uses the end jump instrument to detect the single-sided end jump value of the circular saw blade that has passed the flatness judgment. That is to say, it is determined that this value is the end jump value of the circular saw blade to be tested - but in the actual detection operation, due to the influence of subjective factors of human judgment, the deviation of the flatness of the circular saw blade is often too large, which leads to the above-mentioned currently used detection. The method has poor precision

Embodiment 1

[0020] like figure 1 , 3 As shown in -5, an accurate detection method for the end jump and flatness of a circular saw blade. Before the detection, the surface of the circular saw blade is cleaned, and the circular saw blade 1.0 is centered and fixed to the detection equipment through the flange clamping mechanism 2. On the horizontal shaft 3 connected to the frame 6, the inner displacement detection element 4 and the outer displacement detection element 5 fixed on the frame 6 are respectively located on both sides of the circular saw blade 1.0 and have the same distance from the axis of the horizontal shaft 3, read Take the indication n of the detection point A of the inner surface displacement detection element 4, then remove the circular saw blade 1.0 and turn it over so that the inner surface of the above-mentioned detection faces outwards, then clamp and install it, and adjust the outer displacement detection element 5) so that the indication of the detection point A is ma...

Embodiment 2

[0027] The preferred solution is figure 1 , image 3 -5, the distance between the inner surface displacement detection element 4 and the outer displacement detection element 5 and the axis of the horizontal shaft 3 is (e-10) mm, e is the distance from the bottom of the water tank of the circular saw blade to be measured to the center of the saw blade, this position is measured The end jump value of the circular saw blade has the most practical significance, and the value of the end jump value can basically correspond to the width of the saw gap when cutting.

Embodiment 3

[0029] like Image 6 As shown in -7, in the actual use of this detection method, a single displacement detection element can also be used for detection. It is not necessary to adjust the displacement detection element before batch detection, but each circular saw blade needs to be turned over twice during the detection operation. Clamping, the operation is not as convenient as the method described in Example 1.

[0030] The details are as follows: an accurate detection method for the end jump and flatness of a circular saw blade. The circular saw blade 1 is centered and fixed on the horizontal rotating shaft 3 connected to the detection equipment frame 6 through the flange clamping mechanism 2, and then fixed. The displacement detection element 4.1 on the frame 6 is located on the inner side of the circular saw blade 1. Rotate the clamped circular saw blade 1.1 for at least one turn, read the reading range p1 to q1 of the detection element 4.1, and then turn the circular saw b...

Abstract

The invention discloses an accurate measurement method for end jump and planeness of a circular saw web. According to the method, the circular saw web is fixed to a horizontal rotary shaft which is connected with a rack of a detection device through a flange clamping mechanism in a centering mode, firstly two displacement detection elements fixed to the rack are adjusted and corrected once, and after circular saw webs with the same specification are clamped once and rotate by one circle, the end jump and the planeness are obtained accurately and rapidly through display values of the two displacement detection elements. By means of the method, on the premise that the high practical operability is guaranteed, the fast and accurate measurement of the end jump and the planeness of the circular saw web is achieved; compared with a currently-adopted normal measurement method which is low in efficiency and poor in accuracy, the method has the remarkable advance and prominent advantages.

Description

technical field [0001] The invention relates to a method for detecting index parameters of a circular saw blade, in particular to a method for accurately detecting the end jump and flatness of a circular saw blade. Background technique [0002] Circular saw blades include diamond circular saw blades, carbide circular saw blades, etc. It is a rotary cutting tool with a large diameter-to-thickness ratio. It is easy to use, fast and stable in cutting, and is suitable for stone, ceramics, concrete, Cutting of wood, steel and other materials. In order to achieve good quality cutting, it is necessary to ensure that the circular saw blade cuts straight and the saw path is narrow, and this involves the detection of the end jump and flatness of the circular saw blade. At present, the end jump and flatness detection of the circular saw blade are generally The method is to scrape the circular saw blade with a flat ruler first, and the operator determines the flatness value according t...
