Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic impact test piece processing system, and in particular, an automatic impact test piece processing system suitable for automatically processing and mass producing high-precision impact test pieces. It's about systems.

[Conventional technology]

As a conventional automatic impact test piece processing system,
As described in Publication No. 3-166762, an automatic processing system has been proposed that processes an impact test piece by moving a tool according to a predetermined position with respect to the impact test piece set in a jig. . However, this automatic machining system is not configured to measure the machining accuracy of the tool and correct the movement position of the tool when the machining accuracy deviates from the required accuracy. If this process is continued, there is a problem in that it becomes impossible to ensure the required machining accuracy for the impact test pieces produced.

[Problem to be solved by the invention]

In other words, in the conventional impact test piece automatic processing system described above, consideration is given to mechanical displacement, especially elongation due to heat of the machine spindle, and changes in the reference surface position of the jig that supports the test piece and serves as a reference for processing. do not have. Furthermore, no consideration is given to measuring and correcting machining errors caused by abrasion of machining tools during continuous operation, changes in the material of the test piece material randomly inserted, and changes in the standard and size of the test piece.

As a result, in the conventional automatic impact test piece processing system, a problem arises in that the accuracy of the dimensions of each part of the impact test piece determined based on the jig reference surface no longer satisfies the required accuracy as the processing operation progresses.

The above problem will be specifically explained below using the drawings.

FIG. 13 is a front view of the impact test piece, and FIG. 14 is an end view of the impact test piece. In impact test piece 1, height H and bottom height h
These dimensions H and h are determined by the positional relationship between each reference surface of the jig 2 and the end mill 3 or cutter 4 for notch processing, as shown in FIGS. 15 and 16. It is decided. Therefore, if the positional relationship between the reference surface 5A and the end mill 3 determined by the required accuracy H8 as shown in FIG. 17 changes as shown in FIG. 18 due to the addition of thermal displacement δ due to machine operation, the impact test Required accuracy of piece 1 6
The machining accuracy 7 (experimental value) changes as shown in FIG. 19 (the horizontal axis is the number of test pieces, the vertical axis is the accuracy), and finally exceeds the allowable accuracy of 8, resulting in a machining defect.

FIG. 20 shows an example of the effect that different materials of the test piece 1 have on processing accuracy. This figure first shows machining accuracy status 9 for machining examples of ordinary materials, and then machining accuracy status 10 for machining examples of highly rigid materials or difficult-to-cut materials such as stainless steel.

As is clear from this illustrated example, processing accuracy varies depending on the material of the test piece.

FIG. 21 shows an example in which the type of test piece is the same, but as the machining work progresses, the machining accuracy 7 deviates from the allowable accuracy 8 due to wear of the machining tool and deterioration of sharpness.

FIG. 22 shows an example of the influence that differences in the dimensions of test pieces have on processing accuracy. In this figure, the machining accuracy status 11 of the machining example using the standard test piece 1a is shown first, and then the machining accuracy status 12 of the machining example using the sub-sized test piece 1b with a small thickness is shown. As is clear from this illustrated example, variations in processing accuracy occur due to differences in the dimensions of the test pieces.

In the above, various changes in processing accuracy have been explained, but in reality, the above-mentioned conditions overlap in a complicated manner, and a situation has arisen in which the required accuracy cannot be ensured.

As a means to solve the above problem, for example, the 23rd
As shown in the figure, the target value H8, which always includes the remaining amount, is H8.
Perform the first processing at o+α (Fig. 23 (A)), and measure the dimension H' of the processed specimen 1 using the contact type touch sensor 13.
(Figure 23 (B)), the difference from the target value δ = H
There is a method of making corrections by correcting o-H' and performing final finishing (FIG. 23(C)), which involves temporary housing, measurement, correction and final finishing. However, with this method, the machining time becomes longer due to the temporary setting, resulting in problems such as a decrease in processing capacity and a drastic reduction in the number of test pieces that can be machined before the tool life reaches its end. Furthermore, there are also problems such as an increase in the number of equipment to ensure processing capacity and an increase in equipment downtime due to replacement of tools that have reached the end of their service life.

In view of the above-mentioned problems, the purpose of the present invention is to perform the minimum necessary measurement and correction of the positional relationship and standards of jigs and tools, and thereby perform the required measurements even when machining work is performed continuously for a long time. An object of the present invention is to provide an automatic impact test piece processing system that can ensure and maintain processing accuracy, thereby achieving automation of processing operations and making the most effective use of processing equipment.

Next, the operation of the automatic impact test piece processing system according to the present invention based on the processing machine having the above-mentioned configuration is illustrated in FIGS. 3 to 12.
This will be explained according to the diagram.

First, the concept of measuring and correcting mechanical displacement and the like in the automatic impact test piece processing system and the timing of correction will be explained with reference to FIGS. 3 to 10. As shown in FIG. 3, a mechanical or electrical touch sensor 13 with a known diameter φD and length p is attached to the main shaft 27 of the machine, and the moment it touches the reference surfaces 5A and 5B of the jig 2. By using the machine coordinate values X and Z held inside the machine, the position X of the reference plane position 5A determined in advance by the coordinate values and the machining work program is determined. The difference from +ZO is corrected by changing the position of the processing tool so that the processing accuracy does not exceed the accuracy tolerance range. By performing this correction, the accuracy transition of the test piece shown in Figures 1-9 earlier is changed to the point at which the correction is made (A), as shown in Figure 4.
Since the initial accuracy is restored at , the subsequent machining accuracy again satisfies the required accuracy and is good. By performing the above correction at an appropriate and efficient timing while the processing machine is in operation, the processing accuracy of the processing machine can be constantly maintained within the tolerance range with a minimum number of measurements and corrections.

As a means for measuring the relative position between the position of the reference plane 5A and the center of the machine main shaft 27, a non-contact measuring device such as a laser length measuring device 61 may be used as shown in FIGS. 5 and 6. I can do it. Furthermore, as another modified embodiment, as shown in FIGS. 7 and 8, the correction mechanism 62 may be provided on the side of the jig 2 having the reference surface. In this configuration, the jig 2 includes the guide member 63 at the bottom, and the guide member 6
The correction mechanism 62 has a servo motor 64 and a screw member 65, and rotates the screw 65 by the servo motor 64 according to the amount of correction to move the jig 2. let

Next, when machining test pieces of various materials or sizes, stable machining accuracy can be obtained by measuring and correcting when the material or size changes (a) as shown in Figure 9. I can do it.

Next, if a decrease in accuracy due to wear of the machining tool is a problem, as shown in Figure 10, a preset time (or test (set number of specimens), that is, at point (a), measure the dimensions of the specimen after machining, find the difference from the target value, and make corrections from the next specimen based on this difference to improve machining accuracy. In addition, accuracy can be stabilized.

As mentioned above, the required accuracy, material, size, and
It is configured to check the operating time of the processing machine and the usage time of the processing tool, and is configured to perform measurement and correction at the optimal timing by taking machine displacement etc. into consideration.

Next, the machining process diagrams shown in Figures 11A and 11B and the
An example of a series of processing operations including measurement and correction steps by the automatic impact test piece processing system according to the present invention will be explained using the flowchart shown in FIG. The flowchart shown in FIG. 12 is a diagram for explaining timing of measurement and correction.

In step S1, first, before the line starts operating, the reference surfaces 5A and 5B of the test piece fixing jig 2 are connected to the electric touch sensor 1.
3, and the distance X from the reference position 81. ,io
seek. These values are stored. Next step S2
Now, the notch processing cutter 4 is brought into contact with the reference surface 5B, and the position IC of the cutter 4 at the moment of contact is determined and stored.

The above steps SL and 32 are preparatory work before the machining work, and when these steps are completed, the line using the machining machine 40 is started. In the following machining operations with a machining machine: - As an example, 3
A test piece shall be taken.

These three test pieces are processed and cut one by one from the top of the upright test piece material.

In step S3, the test piece material 82 is put into the jig 22, and at the same time, the touch sensor 13 is used to
The positions X and l of the processing reference planes 5A and 5B from the reference position 81 are measured and stored. In step S4, end mill 3
The first test piece I on the top of the test piece material 82 using
After finishing the top surface of A, temporarily raise the side surface. In step S5, the processing width is measured by the touch sensor 82 (the first
(corresponding to step 93 in Figure 2). In step S6, the difference between the measured actual machining width and the target value is corrected (corresponding to step 94 in FIG. 12), and the end mill 3 is used again to finish the side surface of the specimen IA (step 9
5). Next step S7 is the first test piece I
A is cut by the metal saw 32 while its upper part is grasped by the robot 83, and the first test piece IA is separated from the test piece material 82. The cut specimen IA is gripped once by the robot 83, and then carried into the jig 2, and the clamps 24 and 25 are used to bring the already machined surface into contact with the reference surfaces 5A and 5B of the jig 2. to ensure that it is pressed against the jig 2 (step S8). In the next step S9, the reference plane position X before operation measured in step S1. By correcting the difference between the end mill 3 and the reference plane position X measured in step S3 during operation, the end mill 3 performs temporary hoisting. Thereafter, the position X of the temporarily raised surface is measured using the touch sensor 13 (step 510),
Compare this with the reference plane position
-X, l are calculated, and after correcting the difference from the target value, finishing processing is performed (step 511). In step 812,
The test piece IA is held on the jig 2 with a clamp 24.25, and the notch is cut by correcting the displacement δ, =1, -1 of the reference surface 5B before and after operation with respect to the cutter position Ac when it contacts the reference surface before operation. Machining is performed using the cutter 4 for section processing to form a groove. In the final step S13, the burr generated in the notch is removed using the burr removal tool 33, and the test piece I obtained in this way is
A is carried out from the processing machine by the robot 83.

The processing steps shown in FIGS. 11A and 11B above have been explained focusing only on the processing steps for the first test piece IA taken from the test piece material 82, but in reality, this first test piece The working process for the second test piece is included in the working process for the second test piece, and the working process for the second test piece is partially performed. That is, step Sl of the first test piece IA
1, the finishing end mill 3 moves to the jig 22 and performs step S6 on the second test piece located above the test piece material 82. however,
In step S6 regarding the second test piece, the end mill 3 finishes the top surface and both side surfaces. Thereafter, step S12 is continued for the first test piece IA.

Further, the corrections made during the processing of the first test piece are for dealing with mechanical displacement, standards, material quality, size, etc.

When the processing of the first test piece is completed, a second test piece is then taken from the test piece material 82, and in the process of processing the second test piece, step S3. S4. S5. S9°SIO is omitted, and the second test piece is processed using the correction data obtained in the process of processing the first test piece as is for correction to accommodate mechanical displacement and the like. Therefore, for processing the second test piece, step S6. S7. S8, S
ll, S12. S13 is performed. the last remaining third
The processing steps for the second test piece were also the same as for the second test piece. Looking at the above steps in FIG. 12, they correspond to steps 95 and 98.

When three test pieces are taken from the first test piece material 82, the next test piece material is placed on the jig 22 (if YES in step 99 in FIG. 12).

When processing the second test piece material, if the specifications, materials, and sizes of the test pieces to be taken are the same as those of the first test piece material, then the 2. The processing operation is performed using the same correction values in the same steps as the processing process for the third test piece (if NO in step 93 in FIG. 12). Also, at this time, if it is the correction timing for the reference surface position determined by the machine operating time (or the number of processed test pieces), the measurement in step S3 is performed, and the correction value is updated by comparison with the target value ( (corresponding to steps 91 and 92 in FIG. 12).

In addition, if it is judged that it is time to correct the amount of tool wear based on the usage time of the tool, the second or third
After the 12th test piece is finished, the measurement in step S5 is performed, and the correction data obtained from the comparison based on the difference with the target value is used for correction during subsequent processing of the test piece (12th test piece). (corresponding to steps 96 and 97 in the figure).

In processing the second test piece material, the specifications, material,
If any one of the sizes is different from that of the first test piece material, the same machining step as that performed for the first test piece material described above is performed (step 93 in FIG. 12). 94). Generally speaking, the specifications, materials, and sizes of the nth test piece material and the n+1th test piece material are compared, and if they are all the same, step S3. S4, 35. S9. SIO is omitted, and step S3 is additionally executed when the timing at which it is necessary to correct the machine displacement based on the machine operating time is reached for the remaining steps, and it is necessary to correct tool wear based on the tool usage period. When a certain timing is reached, an additional test piece measurement step is performed after finishing. Furthermore, if any one of the specifications, materials, and sizes is different, all steps from step 83 to step S13 are executed.

Through the processing steps described above, it is possible to continuously perform high-precision processing on various test piece materials that are randomly input into the processing machine 40, and to rapidly produce large quantities of various types of impact test pieces. It can be made.

As mentioned above, we have adopted a method that measures and corrects various work quantities at the optimal timing during machining work, and corrects machine displacement, tool escape amount, and tool wear amount. It is possible to realize an automatic impact test piece processing system that can maintain processing accuracy and make maximum effective use of machines and tools.

In addition, in the above embodiment, the timing at which the reference plane position of the jig 2 is measured is not necessarily immediately before the related machining. This occurs in order to make effective use of processing waiting time that occurs in connection with peripheral equipment, such as robots for handling test specimens, automatic processing tool changing devices, etc., and to reduce tool changing time. The above measurement may be performed during any step immediately before the related processing.

Further, the standards for the test piece include, for example, JIS and AsTM (American standard). Therefore, considering these differences in standards, when measuring and correcting the displacement between the machining reference plane and the machine, the timing changes depending on the standard; for example, in the case of JIS Standard 7, the intervals are long; The ASTM standard results in short intervals.

In addition, we have optimized the timing of measurements and corrections, minimized the number of times, and minimized the time-consuming processes of temporary finishing, measurement, and correction finishing.
