Technical Field

The present invention relates to a one-dimensional measuring machine and a program that improve workability in two-dimensional coordinate measurement.

Background

The one-dimensional measuring machine is a device as follows: the measurement device is provided with a measurement probe that is provided so as to be movable in one direction, and measures the dimension of a measurement target by bringing the measurement probe into contact with a measurement portion of the measurement target. A so-called height measuring machine is generally known which measures coordinates in a height direction by vertically moving a measuring stylus (see, for example, patent document 1).

In the height measuring machine, there are products in which coordinate values in the height direction are expressed only by scales or numerical values as measurement results, and there are products in which, for example, the diameter of a hole, a two-dimensional coordinate of the center, and the like, which are measurement elements existing in the object to be measured, can be measured.

For example, when the two-dimensional coordinates of the center of a circular hole existing in a measurement object are measured by a height measuring machine, the measurement object is placed on a flat plate or the like, the height coordinates of the center of the hole in this state are first measured, and then the measurement object is rotated by 90 degrees, and then the height coordinates of the center of the hole in this state are measured, thereby obtaining the two-dimensional coordinates of the center of the hole.

An example of a specific measurement process is described with reference to fig. 1. Fig. 1 is a diagram illustrating a process of measuring two-dimensional coordinates of a measurement element with respect to a measurement object W including three measurement elements, i.e., a circle 1, a circle 2, and a circle 3, using a height measuring machine. Specifically, (a) of fig. 1 shows a state where the x-axis is located on the plane surface and the height direction is the z-axis direction, and (b) of fig. 1 shows a state where the z-axis is located on the plane surface and the height direction is the x-axis direction after the object to be measured W is rotated by 90 degrees together with the x-axis and the z-axis.

First, in the state of fig. 1 (a), the z-axis coordinate of the center is measured in the order of circle 1, circle 2, and circle 3. Further, Z-axis coordinate Z of the center of each circle_CThe Z-axis coordinate Z of the uppermost part of the circle is actually measured by the measuring machine_UAnd the lowest Z-axis coordinate Z_LThen as Z-axis coordinate Z_UAnd Z-axis coordinate Z_LIs calculated from the median value of (a).

Next, as shown in fig. 1 (b), the x-axis direction is set to the height direction by rotating the measurement object W by 90 degrees, and then the x-axis coordinate of the center is measured in the order of circle 1, circle 2, and circle 3. In addition to this, the present invention is,x-axis coordinate X of each center_CThe X-axis coordinate X of the uppermost part of the circle is actually measured by the measuring machine_UWith the X-axis coordinate X of the lowermost part_LThen as X-axis coordinate X_UWith X-axis coordinate X_LIs calculated from the median value of (a).

Then, the measurement result of the Z-axis coordinate and the measurement result of the X-axis coordinate are synthesized in the order of measurement as the measurement result of the two-dimensional coordinate (Z, X). That is, the first Z-axis coordinate Z measured as the Z-axis coordinate_c1With the first x-axis coordinate x measured as the x-axis coordinate_c1Synthesized to output two-dimensional coordinates (Z) as a circle 1_c1，x_c1) Similarly, the second and third measured Z-axis coordinates and x-axis coordinates are also synthesized and outputted as two-dimensional coordinates (Z-axis coordinates) of the circle 2 and the circle 3, respectively_c2，x_c2)、(Z_c3，x_c3)。

Disclosure of Invention

Problems to be solved by the invention

When a method of combining measurement results shown in the background art, that is, a method of combining measurement results immediately before and after rotation in the order of measurement is used to measure two-dimensional coordinates of a plurality of measurement elements of a measurement target using a one-dimensional measuring machine such as a height measuring machine, it is necessary to make the order of measurement of each measurement element the same before and after rotation in order to obtain an appropriate measurement result for each measurement element.

In addition, in such a case, when there are many measurement elements or when the measurement object has a complicated shape, the measurement order of each measurement element is likely to be inconsistent before and after the rotation. Therefore, the operator needs to take a careful attention to measure the shape of the object to be measured, the number of the measurement element, and the like, for example, and there is a problem in workability.

The invention aims to provide a one-dimensional measuring machine and a recording medium, which can improve the operation performance when two-dimensional coordinate measurement is carried out.

Means for solving the problems

The one-dimensional measuring machine of the present invention measures two-dimensional coordinates of each of a plurality of measurement elements in a measurement object by: the one-dimensional measuring machine measures one-dimensional coordinates for each measurement element of a measurement object, rotates the measurement object by a predetermined angle in a predetermined direction, and then measures one-dimensional coordinates for each measurement element of the rotated measurement object, the one-dimensional measuring machine including: a display unit; a display control unit that causes a display unit to display a rough arrangement and a measurement order of each of a plurality of measurement elements in a measurement target object based on first input information, and causes the display unit to display the arrangement and the measurement order of each of the plurality of measurement elements in a state in which a positional relationship of each of the measurement elements is maintained, the arrangement and the measurement order being rotated by a predetermined angle in a predetermined direction; and an input unit that accepts input of the first input information and the second input information.

According to the one-dimensional measuring machine configured as described above, when measuring two-dimensional coordinates, it is possible to confirm the arrangement and the measurement order of the plurality of measurement elements on the display unit, and to perform measurement without causing inconsistency in the measurement order before and after rotation of the measurement object, and therefore, it is not necessary to perform a task such as recording, and it is possible to improve the workability.

The display control means may reflect a result of measurement of one-dimensional coordinates of the measurement target object performed during a period in which the display based on the first input information is being performed, in the arranged display, and reflect a result of measurement of one-dimensional coordinates of the measurement target object after rotation performed by the measurement control means during a period in which the display based on the second input information is being performed, in the arranged rotated display.

In this way, the arrangement of the measurement elements is displayed on the display section in a manner close to the actual arrangement, and therefore, the work can be performed more reliably.

The functions of the display control unit of the one-dimensional measuring machine of the present invention can be described in a program and realized by executing the program by a computer.

Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. In the following description and the drawings, the same functional portions are denoted by the same reference numerals, and the description of the functional portions already described is omitted or is only described to the extent necessary.

The one-dimensional measuring machine according to the present invention is realized by adding a function of a display control means to a conventional one-dimensional measuring machine that measures two-dimensional coordinates of each of a plurality of measurement elements in a measurement target object by: one-dimensional coordinates are measured for each measurement element of the measurement object, and after the measurement object is rotated by a predetermined angle in a predetermined direction, one-dimensional coordinates are measured for each measurement element of the rotated measurement object.

The present invention is applicable to any type of one-dimensional measuring machine as long as the measuring unit is moved in one-dimensional direction to measure the object to be measured. The following description will be given taking a case where the one-dimensional measuring machine is a height measuring machine as an example.

[ Structure of height measuring machine ]

Fig. 2 is a diagram showing a configuration example of the height measuring machine 100. The height measuring machine 100 includes a position detecting unit 10 and a data processing unit 20.

The position detection unit 10 includes a support 11, a linear scale 12, a detection head 13, and a stylus 14.

The support 11 is provided with a linear scale 12 whose height direction is a length measurement direction, and supports the detection head 13 so as to be movable along the length measurement direction of the linear scale 12.

The detection head 13 outputs a signal indicating the number of divisions that the operator moves the detection head 13 to pass through on the linear scale 12.

The probe 14 is a probe fixed to the detection head 13, and the operator manually moves the probe 14 so as to contact the measurement element of the object W to be measured.

The data processing unit 20 is a computer and includes a counting unit 21, a storage unit 22, a calculation unit 23, an input unit 24, and a display unit 25.

The counting section 21 determines the current position of the detection head 13 based on the signal output from the detection head 13.

The storage unit 22 is an arbitrary storage unit that stores current position information of the detection head 13, a program for realizing each unit of the present invention, and the like.

The arithmetic unit 23 is a CPU that reads out a program from the storage unit 22 and executes the program.

The input unit 24 is any type of input means such as a keyboard, a mouse, and a touch panel display integrated with the display unit 25, which are used by the operator to input the first input information and the second input information.

The display unit 25 is any type of display means such as a liquid crystal display that displays information related to measurement.

The data processing unit 20 does not need to have an integral structure, and at least one of the storage unit 22, the input unit 24, and the display unit 25 may be provided outside the main body connected by any type of wired communication or wireless communication.

[ function of display control Unit ]

The display control means first causes the display unit 25 to display the approximate arrangement and the measurement order of each of the plurality of measurement elements in the measurement target object based on the first input information.

The first input information is information of the approximate arrangement and measurement order of each of the plurality of measurement elements in the measurement target object, which is input by the operator through the input unit 24.

In order to facilitate the operator to input the first input information, the display control unit may be configured to cause the display unit 25 to display an input screen, for example, and the operator may input information on the input screen through the input unit 24.

For example, the display control means causes the display unit 25 to display a two-dimensional input screen having the bottom direction of the measurement target W as the x-axis and the height direction as the z-axis as shown in fig. 3 (a), and waits for input of information from the input unit 24. When the object to be measured W includes four measurement elements, i.e., a circle 1, a circle 2, a circle 3, and a circle 4, in the arrangement shown in fig. 3 (b) and it is desired to perform measurement in the order of the circle numbers, the operator inputs the approximate arrangement of the four measurement elements on the two-dimensional input screen shown in fig. 3 (a) by clicking with a mouse or the like. In this case, the order in which the arrangement is input may be displayed on the display unit 25 as it is as the measurement order, or the order may be displayed after the arrangement is input and displayed and the order may be input separately. Thereby, the arrangement of the measurement elements and the measurement procedure corresponding to the arrangement of the measurement elements of the object to be measured W are displayed on the display unit 25 as shown in fig. 3 (c), for example.

The operator performs measurement of the z-axis coordinate of each measurement element in the displayed measurement order while referring to the arrangement and measurement order of the measurement elements displayed on the display unit 25 shown in fig. 3 (c). This makes it possible to perform measurement without mistaking a predetermined measurement sequence.

When the measurement is performed, the display control unit may acquire a measurement result obtained for the z-axis coordinate and reflect the measurement result into the configured display. Fig. 3 (d) shows an example after reflection. By reflecting the measurement order in this manner, the ratio of the diameters of the measurement elements in the z-axis direction displayed corresponds to the actual situation, and therefore the risk of mistaking the measurement order can be further reduced.

After the measurement of the z-axis coordinate is completed, the operator rotates the measurement object W by a predetermined angle in a predetermined direction. Fig. 4 (a) shows an example in which the measurement target W shown in fig. 3 (b) is rotated by 90 degrees counterclockwise.

After rotating the measurement target W by a predetermined angle, the operator inputs second input information through the input unit 24. The second input information is a command for rotating the entire arrangement of the measurement elements displayed on the display unit 25 in response to the input of the first input information by a predetermined angle in a predetermined direction while maintaining the positional relationship of the measurement elements. The second input information may include information on the rotation angle of the object W to be measured.

The display control means causes the display unit 25 to display, based on the second input information, the arrangement and the measurement order of each of the plurality of measurement elements that are rotated by a predetermined angle in the direction in which the object to be measured W is rotated, in the entire arrangement of the measurement elements displayed on the display unit 25 in response to the input of the first input information. Fig. 4 (b) shows an example in which the entire arrangement of the measurement elements displayed on the display unit 25 in response to the input of the first input information shown in fig. 3 (d) is rotated 90 degrees counterclockwise.

The operator performs the measurement of the x-axis coordinate of each measurement element in the displayed measurement order while referring to the arrangement and measurement order of the measurement elements displayed on the display unit 25 shown in fig. 4 (b). This makes it possible to perform measurement without mistaking a predetermined measurement sequence.

When the measurement is performed, the display control unit may acquire a measurement result obtained for the x-axis coordinate and reflect the measurement result into the configured display. Fig. 4 (c) shows an example after reflection. Since the ratio of the diameters of the measurement elements displayed in the x-axis direction is in accordance with the actual situation by reflecting in this manner, if the measurement order is correct, the ratio of the arrangement and size of the circle displayed on the display unit 25 is substantially the same as the ratio of the arrangement and size of the circle of the object W to be measured. Therefore, whether the measurement sequence is correct can be quickly confirmed.

When the measurement results of the one-dimensional coordinates of the measurement object W before and after the rotation are obtained, and the measurement object W is rotated by 90 degrees from the state of fig. 3 (b) to the state of fig. 4 (a), the two-dimensional coordinates can be obtained by directly combining the measurement results before and after the rotation for each measurement element.

On the other hand, when the object to be measured W is rotated at an angle other than 90 degrees, the measurement result after rotation can be converted for each measurement element based on the measurement result before rotation and the actual angle of rotation, and the converted measurement result after rotation and the measurement result measured before rotation can be combined to obtain two-dimensional coordinates.

[ method of adding function of display control means ]

The function of adding the display control means to the height measuring machine 100 can be realized by adding a function section dedicated to the display control means to the data processing section 20, and in addition, it can be realized by storing a program describing the function of the display control means in the storage section 22 in advance, and by reading out and executing the program by the arithmetic section 23.

The function (coordinate synthesis means) of obtaining two-dimensional coordinates by obtaining the measurement results of the one-dimensional coordinates of the measurement object W before and after the rotation, and then synthesizing the measurement results as they are, or by performing conversion processing and synthesizing the measurement results can be realized by adding a function unit dedicated to the function to the data processing unit 20, and in addition, can be realized by storing a program describing the function in the storage unit 22 in advance, and by reading out and executing the program by the arithmetic unit 23. The information on the rotation angle of the measurement target W in the case of performing the conversion process may be, for example, information input so as to be included in the second input information.

According to the one-dimensional measuring machine of the present invention described above, when measuring two-dimensional coordinates, the arrangement and the measurement order of a plurality of measurement elements can be confirmed on the display unit, and the measurement can be performed without causing inconsistency in the measurement order before and after the rotation of the measurement object, so that it is not necessary to perform a task such as recording, and the workability can be improved.

The embodiments are illustrative, and any configuration having substantially the same configuration as the technical idea described in the claims of the present invention and having the same operation and effect is included in the scope of the present invention. That is, the present invention can be modified as appropriate within the scope of the technical idea presented in the present invention, and the modifications and improvements are also included in the scope of the present invention.
