Abstract

The utility model relates to a bending measuring apparatus which is used to measure the bending of a band saw blade or a steel strip; the bending measuring apparatus is provided with a long base with the top surface which is of a plane; the left end and the right end of the top surface of the long base are respectively provided with a left positioning bearing and a right positioning bearing which are on the same side of the top surface; the axes of the left positioning bearing and the right positioning bearing are vertical to the top surface of the long base; a dial gauge is fixedly arranged on the long base through an installation base, and the dial gauge is arranged between the left positioning bearing and the right positioning bearing; and the axis of the measuring head of the dial gauge is in parallel with the top surface. The device can measure the bending of the band saw blade or the steel strip within the short measuring length, and has the advantages of simple structure, high measurement precision and convenient operation.

Description

Cutter is bent measuring instrument
Technical field
The utility model relates to a kind of bands for band or curved device of steel band cutter measured.
Background technology
The cutter of bands for band or steel band is curved to be meant bands for band or steel band along its length deflection in certain length.The curved cutting ability influence to bands for band of cutter is very big.The method that original old-fashioned survey cutter is bent as shown in Figure 1, it is that bands for band 9 is placed on the ground, with single line 10 after 2 of measured bands for band certain-length L are stretching, with the curved h of general ruler measurement cutter, because measuring accuracy low (more than 2mm), so L needs 5~6m and can go out to measure the curved h of cutter comparatively exactly after long.If curved having reached more than the 10mm of bands for band cutter in long length, it is curved then can to measure cutter with old-fashioned method.But under a lot of situations, bands for band falls short of, and perhaps its free random elongation can only can not measured in the short distance very much, and existing method just can not effectively be measured described cutter and bend, and the measuring accuracy of old-fashioned method also has much room for improvement.
The utility model content
The technical problems to be solved in the utility model is, defective at the prior art existence, design the curved measuring instrument of a kind of cutter, the curved measurement of cutter that is used for bands for band or steel band, can be in short measurement length carry out that cutter is curved to be measured to bands for band or steel band, and it is simple in structure, measuring accuracy is high, easy and simple to handle.
The technical solution of the utility model is, the curved measuring instrument of described cutter is provided with the strip base that end face is the plane, corresponding left alignment bearing and the right alignment bearing that is positioned at described end face the same side that be provided with in the left and right two ends of the end face of this base, the axis normal of described left alignment bearing and right alignment bearing is in the strip base top surface, clock gauge through mount pad be fixedly mounted on the strip base and this clock gauge between described left alignment bearing and right alignment bearing, the parallel axes of the measuring head of described clock gauge is in described end face.
Below the utility model made further specify.
Referring to Fig. 2, the curved measuring instrument of described cutter is provided with the strip base that end face is the plane, corresponding left alignment bearing and the right alignment bearing that is positioned at described end face the same side that be provided with in the left and right two ends of the end face of this strip base, the axis normal of described left alignment bearing and right alignment bearing is in the strip base top surface, clock gauge through mount pad be fixedly mounted on the strip base and this clock gauge between described left alignment bearing and right alignment bearing, the parallel axes of the measuring head of described clock gauge is in described end face.
During actual measurement, as shown in Figure 1, tested bands for band one side leans against a side of described left alignment bearing and right alignment bearing, and the measuring head of clock gauge can accurately be measured the cutter of the bands for band between left alignment bearing and the right alignment bearing and bend.
Because the axis normal of described left alignment bearing and right alignment bearing is in the strip base top surface, the upper-lower position difference of placing owing to bands for band in can effectively preventing to measure causes measuring difference.When measured value is zero, no matter which position left alignment bearing or right alignment bearing rotate in, the left anchor point (being the contact point of left alignment bearing and bands for band) of left side alignment bearing, and the right anchor point (being the contact point of right alignment bearing and bands for band) of measurement point of the measuring head of clock gauge (being the contact point of measuring head and bands for band) and right alignment bearing is all the time on same straight line, and its straightness error is not more than their central point of 0.02mm. also at sustained height.Minor increment between left side anchor point and the measurement point can be only for being 500mm.The measuring accuracy of this device can reach 0.05mm, and the relative prior art of measuring accuracy is greatly improved, and has avoided the defective that sample length is long, measuring accuracy is low; Also can detect curved variation of cutter of interior steel band of short distance or bands for band, reach the purpose of curved situation of change of analytic band saw blade cutter or rule.
As known from the above, the utility model is the curved measuring instrument of a kind of cutter, is used for curved measurement of cutter of bands for band or steel band, can be in short measurement length carry out to bands for band or steel band that cutter is curved to be measured, and it is simple in structure, measuring accuracy is high, easy and simple to handle.

Fig. 2 is the structural representation of a kind of embodiment of the utility model.
In the drawings:
1-strip base, 2-left alignment bearing, 3-right alignment bearing,
4-clock gauge, 5-measuring head, 6-left anchor point,
7-right anchor point, 8-measurement point, 9-bands for band,
10-line, 11-mount pad.
Embodiment
As Fig. 2, the curved measuring instrument of cutter of the present utility model is provided with the strip base 1 that end face is the plane, corresponding left alignment bearing 2 and the right alignment bearing 3 that is positioned at described end face the same side that be provided with in the left and right two ends of the end face of this strip base 1, the axis normal of described left alignment bearing 2 and right alignment bearing 3 is in strip base 1 end face, clock gauge 4 is fixedly mounted on the strip base 1 and the point midway of this clock gauge 4 between described left alignment bearing 2 and right alignment bearing 3 through mount pad 11, and the parallel axes of the measuring head 5 of described clock gauge 4 is in described end face.Wherein, strip base 1 length can be designed to 700mm, thickness 15mm, and wide is 50mm; Thickness thicker and can prevent the distortion, the most handy aluminium alloy manufacturing is with weight reduction; The upper and lower surface of strip base 1 should guarantee higher flatness, and above, lower surface is parallel is advisable.
