In the prior art, the main roller for cutting of the wire cutting machine comprises a roller body and a roller shaft, and the roller body is provided with a notch groove. Taking a square cutting machine as an example, before the main roller is installed on the square cutting machine, the accurate distance between the notch groove and the notch groove needs to be obtained, so that a cut product with abnormal size can be prevented from being obtained, the processing precision is favorably improved, and a square rod with abnormal size due to the size error of the main roller is prevented from being processed. Therefore, a measuring tool can be used to accurately measure the distance from the end surface of the main roll to the notch, thereby obtaining an accurate distance from the notch. The utility model provides a measurement frock of main roll for cutting, this measurement frock can the accurate measurement terminal surface and the interval between the inslot on the roll body.

The embodiment of the utility model provides a measuring tool for a main roller for cutting, which is shown in reference figures 1 to 8 and comprises a calibration assembly and a distance measuring element 1. The calibration assembly has at least two calibration elements, at least one of which is a reference calibration element 2 for calibrating the end face 103; at least one of the calibration pieces is a sliding calibration piece 3 used for calibrating the position of the corresponding notch groove; the distance measuring element 1 is used to measure the distance between the reference marker 2 and the sliding marker 3.

When the cutting main roller is measured, the end face of the roller shaft can be used as a measuring reference surface to measure the distance between the end face and different notches. The position of the end surface 103 can be calibrated by the reference calibration 2 and the position of the groove can be calibrated by the sliding calibration 3, and the distance between these two calibration can be measured by means of the distance measuring element 1, so that the distance between the end surface 103 and the groove calibrated by the sliding calibration 3 can be obtained. Therefore, the positions of the end surface 103 and the notch can be conveniently and accurately marked by utilizing the calibration piece, and the measuring accuracy can be improved. Therefore, the measuring tool for the main roller for cutting provided by the embodiment of the utility model can accurately measure the distance between the end surface 103 and the notch on the roller body 102. After the distance from each notch to the end surface 103 is obtained, the distance from notch to notch can be calculated.

The number of the reference markers 2 may be one or more; the number of the sliding markers 3 can be one or more; the present disclosure is not limited. For example, the number of the reference markers 2 may be one, the number of the sliding markers 3 may be two, and two notches may be simultaneously marked by the two sliding markers 3, so as to obtain the distance from each of the two notches to the end surface 103. Certainly, the same notch can be calibrated by two sliding type calibration pieces 3, so that the distance data between the two sliding type calibration pieces 3 and the reference calibration piece 2 can be obtained, and the average value of the two distance data is used as the distance between the end surface 103 and the corresponding notch, which is beneficial to improving the accuracy of measurement. For another example, the number of the reference markers 2 may be two, the number of the sliding markers 3 may be two, and no matter whether two sliding markers 3 are calibrated to the same notch groove or to one notch groove respectively, two distance data may be obtained, where the two distance data are distance data between the sliding markers 3 and two reference markers 2 respectively, and an average value of the two distance data is used as a distance between the end surface 103 and the corresponding notch groove, which is beneficial to improving the accuracy of measurement.

Wherein, the distancer can be laser range finder, infrared range finder or ultrasonic ranging appearance, and this disclosure does not limit.

In one possible implementation, the distance measuring element 1 may be a scale. This allows the distance between the reference mark 2 and the sliding mark 3 to be measured using a ruler.

In an example, referring to fig. 1 and 3, the extending direction of the scale is the same as the extending direction of the roller shaft 101, both the sliding type marker 3 and the reference marker 2 can be slidably mounted on the scale, and both the sliding type marker 3 and the reference marker 2 are provided with indication arrows pointing to the scale marks. In this way, the distance between the sliding marker 3 and the reference marker 2 can be accurately measured using a scale.

In another example, referring to fig. 4 to 8, the sliding scale 3 may be slidably mounted on the scale, while the reference scale 2 is fixedly connected to the scale or fixed in relative position to the scale.

In a possible implementation, as shown with reference to fig. 4 to 8, the ranging element 1 can comprise a first scale 11 simulating a main ruler of the vernier caliper and a second scale 12 simulating a secondary ruler of the vernier caliper. The relative position of the reference marker 2 and the first scale 11 is fixed. The second scale 12 is slidably mounted on the first scale 11, and the slidable scale 3 is mounted on the second scale 12 so as to slide on the first scale 11 following the second scale 12. The distance between the sliding scale 3 and the reference scale 2 can thus be obtained by the first scale 11 and the second scale 12. Further, since the first scale 11 and the second scale 12 simulate the principle of a vernier caliper, the accuracy of measurement can be improved. During specific measurement, after the end face 103 is calibrated by the reference calibration piece 2, the second scale 12 is slid, so that the sliding calibration piece 3 extends into the corresponding groove to calibrate the groove position, and then the scale values on the first scale 11 and the second scale 12 are read. Wherein, first scale 11 can be the main scale to the millimeter is the unit, and second scale 12 is the sub-scale of vernier, is carved with on the sub-scale of vernier with certain length divide equally into the scale mark of a plurality of divisions, for example: when nine millimeters are divided into ten divisions, the precision is 0.1 mm; when the nineteen millimeters are divided into twenty grids, the precision is 0.05 mm; when forty-nine millimeters are divided into fifty grids, the precision is 0.02 mm; twenty or fifty bins. The reading method comprises the following steps: firstly, reading a millimeter integer on the first scale 11 with the zero scale mark of the second scale 12 as the standard, then looking at the fact that the second scale mark on the vernier is aligned with the scale mark of the scale body, for example, the third scale mark is aligned, the decimal part of 0.06mm can be obtained by multiplying the precision by three, for example, 0.02mm, and then adding the integral part and the decimal part to obtain the total size. In addition, the reference marker 2 may be fixedly connected to the first scale 11, or may be detachably mounted on the first scale 11, as long as the relative position between the reference marker 2 and the first scale 11 is fixed.

In order to facilitate measurement, the measurement tool provided by the embodiment of the utility model further comprises a bearing table 5, wherein the bearing table 5 is used for bearing the main roller, a limiting structure matched with the main roller is arranged on the bearing table 5, and the limiting structure is used for limiting the main roller to freely move relative to the bearing table 5; therefore, the main roller can be placed on the bearing table 5, and position calibration and measurement are convenient to carry out. The calibration assembly can be mounted on the bearing table 5, and the distance measuring element 1 can also be mounted on the bearing table 5. For example, a guide bar parallel to the axial direction of the roller shaft 101 is arranged on the bearing platform 5, the sliding type marker 3 is slidably mounted on the guide bar, and the scale is mounted near the guide bar in a manner parallel to the guide bar, so that after the main roller is placed on the bearing platform 5 in a manner of being matched with the limiting structure, the corresponding scale value on the nearby scale can be read out by moving the sliding type marker 3 to the position corresponding to the notch groove. Therefore, the measurement is facilitated by the way the carrier table 5 maintains the position of the main roller.

In a possible embodiment, referring to fig. 1 and 3, the roller shaft 101 may have a step surface, and the limiting structure may be configured as a positioning hole opened on the bearing surface of the bearing table 5, the roller shaft 101 is inserted into the positioning hole along the gravity direction, and the step surface of the roller shaft 101 abuts against the bearing surface; in this way, the main roller can rest on the carrier table 5 limited by the positioning holes, and then can be measured by the calibration assembly and the distance measuring element 1.

In one possible embodiment, referring to fig. 4 and 7, the bearing table 5 may have an arc-shaped bearing surface 51, the arc-shaped bearing surface 51 extends along a straight line, the straight line extends at an angle of 0 ° or an acute angle with respect to the horizontal plane, and the arc-shaped bearing surface 51 is matched with the outer circumference of the roller 102. In this way, the arc bearing surface 51 can bear the main roller and prevent the roller body 102 from rolling, so that the main roller can be placed on the bearing table 5, and then the distance measurement can be performed by using the calibration assembly and the distance measuring element 1. In one example, the arc bearing surface 51 and the roller shaft may extend in a horizontal direction, so that the main roller may stably rest on the arc bearing surface 51. In another example, the linear extension of the curved bearing surface 51 may have an acute angle with the horizontal, i.e. the curved bearing surface 51 is inclined with an upper end and a lower end in the extension, and the reference marker 2 is located at the lower end of the curved bearing surface 51 when the main roll is placed on the curved bearing surface 51, so that the reference marker 2 can prevent the main roll from sliding down while marking the position of the end surface 103. In this case, the reference marker 2 may be a plate fixed to the carrier table 5 as described below.

In a possible implementation, and with reference to fig. 1 and 3, the sliding index 3 can be a pointer having a needle for reaching into the notch, the needle being able to form-fit with the notch. In this way, the position of the notch is precisely calibrated when the needle can be inserted into the notch with a positive fit.

As shown in fig. 3, the pointer may be retractable. Therefore, the pointer can be contracted in advance, so that the main roller can be avoided in the process of placing the main roller on the bearing table 5, and other notches can be avoided in the process of sliding the pointer to the corresponding notches. Of course, the pointer may have a fixed length, as shown in fig. 6 to 8, after the main roller is placed on the bearing table 5 in a manner that the roller shaft 101 extends in the horizontal direction, and the end surface 103 is calibrated, the main roller may be manually moved to avoid the sliding pointer, so that the pointer can slide to a position corresponding to the notch, and then the main roller is put back to the original position, and then the pointer is moved within the notch limited range, so that the pointer can accurately calibrate the position of the notch.

The angle between the extending direction of the pointer and the sliding direction is greater than or equal to 90 degrees and less than 180 degrees. That is, the direction of extension of the pointer is adapted to the direction of the opening of the notch so that the needle can be inserted into the notch with a positive fit. For example, the opening direction of the notch is perpendicular to the sliding direction of the pointer, and the angle between the extending direction of the pointer and the sliding direction is equal to 90 °.

In a possible implementation, in order to guide the sliding index 3 sliding along the extension direction of the roller 101 in order to accurately index the position of the notch with respect to the end surface 103, the indexing assembly further comprises a guide 4, the guide 4 being guided in the same direction as the extension direction of the roller 101, the sliding index 3 being slidably mounted on the guide 4.

In one example, referring to fig. 1 and 3, the guide member 4 may be a guide rod, and the sliding type index member 3 is slidably fitted on the guide rod.

In a possible embodiment, the reference calibration member 2 has a calibration surface for abutting the end surface 103, and when the calibration surface abuts the end surface 103, the reference calibration member 2 can calibrate the position of the end surface 103. The reference marker 2 may be slidably mounted on the guide 4, or may be fixed relative to the guide 4.

For another example, referring to fig. 4 to 6, when the roller shaft 101 is placed on the carrier table 5 in such a manner as to extend in the horizontal direction, the reference mark 2 may be fixedly mounted on the carrier table 5, and the relative position with the first scale that serves as a guide is fixed. During measurement, only the main roller needs to be moved to enable the end surface 103 to be attached to the calibration surface, then the position of the notch can be calibrated by using the sliding type calibration piece 3 under the condition that the position of the main roller relative to the bearing table 5 is kept fixed, and then the distance between the notch and the end surface 103 can be measured through the distance measuring element 1 (such as the first scale 11 and the second scale 12).

In a possible embodiment, illustrated with reference to fig. 1 and 3, the reference marker 2 can be a telescopic rod.

Therefore, the reference mark piece 2 can be contracted in advance, so that the main roller can be avoided in the process of placing the main roller on the bearing platform 5, and other notches can be avoided in the process of sliding the pointer to the corresponding notches. For example, when the roller shaft 101 is inserted into the positioning hole in the gravity direction, the telescopic rod is first retracted, and after the roller shaft 101 is inserted into position, the telescopic rod is further extended to fit the calibration surface to the end surface 103. Therefore, the condition that the size of the roller shaft 101 has errors can be avoided, and the roller shaft 101 is pressed on the telescopic rod under the action of gravity to cause inaccurate calibration of the position of the end face 103. Alternatively, the telescoping rods may be slidably mounted on the guides 4 to accommodate different sizes of rollers 101.

In another possible embodiment, as shown with reference to fig. 4 to 8, the reference marker 2 may be configured as a plate. One side of the plate body may be used as a calibration surface. The plate body can be slidably mounted on the guide 4 to accommodate different sizes of roller shafts 101. When the main roller is placed on the carrier table 5 so that the roller shaft 101 extends in the horizontal direction, the plate body may be fixedly attached to the carrier table 5 and the position relative to the guide 4 may be fixed. When the distance measuring element 1 is a scale fixed on the bearing table 5, the relative position between the calibration surface of the plate body and the scale is fixed, when the end surface 103 of the main roller is attached to the calibration surface and the main roller is placed on the bearing table 5, the sliding type calibration piece 3 is moved to calibrate the position of the notch, and then the distance between the notch and the end surface 103 can be obtained through the scale.

Further, as shown in fig. 2, the end surface of the roller shaft 101 may be a stepped surface, and any stepped surface may be used as the end surface 103. The calibration surface and the end surface 103 may be flat, which may improve the accuracy of the calibration.

Then, the position of the groove is calibrated by using the sliding type calibration piece 3, and the scale value on the scale corresponding to the sliding type calibration piece 3 is read out. The distance between the reference scale 2 and the sliding scale 3 is calculated from the two scale values.

Referring to fig. 4 to 8, the bearing platform 5 has an arc-shaped bearing surface 51, the reference marker 2 may be a plate fixed on the bearing platform, the distance measuring component 1 may include the first scale 11 and the second scale 12, the first scale 11 is fixed on the bearing platform, the sliding marker 3 may be a pointer fixedly installed on the second scale 12 in a non-retractable manner, and the pointer corresponds to a zero scale line of the second scale 12.
