BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a machined member positioning method and apparatus for setting a machined position of a machined member when performing various kinds of machining.

[0002]

2. Description of the Related Art Conventionally, when performing intermediate processing of a long material such as an aluminum extruded die material, a stopper for abutting the end of the long material is placed so that the machining die is accurately positioned at a predetermined machining position. It is provided and positioned. The position of this stopper is generally set manually by the operator.

However, in the case of the manual operation by the worker of the above-mentioned conventional technique, the mold and the stopper must be manually aligned, which results in the disadvantage that it takes a lot of preparation work. In addition, if the object to be machined or the mold is changed, the alignment must be correctly redone again, which is inefficient. In the case of the above-mentioned conventional press machine that automatically sets the stopper position, the origin of the press machine on the press machine side and the bottom of the press machine are set so that the origin of the mold with respect to the stopper remains constant even if the mold is replaced. Since the processing plate origin of the mold plate is aligned, it is necessary to accurately align the respective origin positions of the mold and the press machine in the same manner as the manual positioning operation of the stopper. The work was troublesome. Further, since it is necessary to align the origin of the press machine with the origin of the die machining position, there is a drawback that a die without indication of the origin position cannot be used. Further, in the case of a mold without the display of the origin position, it is necessary to display the origin position, which is inconvenient when using a large number of molds or using existing molds.

The present invention has been made in view of the above-mentioned problems of the prior art, and provides a method and apparatus for positioning a processed member, which enables simple and accurate automatic positioning of a stopper and has a wide range of use. To aim.

It is formed so that it can be inserted into the hole 40.

As shown in FIGS. 1 and 5, the positioning device 30 is provided with a stopper 50 for accurately setting the processing position of the processing member 48 pressed by the mold 11.
The stopper 50 is provided so as to be movable in the longitudinal direction of the processing member 48 by a ball screw mechanism (not shown) and a guide bar 52. Stopper 50 and guide bar 52
Is provided on a support base 54, and a drive motor 56 as a drive device for the stopper 50 is attached to the support base 54 via a ball screw mechanism. In addition, the support base 54
Is fixed to the installation portion 60 of the lifting device 58, and the lifting device 5
8 is provided in the main body 62. Further, the main body 62
A caster 64 is attached to the.

As shown in FIG. 6, a positioning control device 66 having a built-in CPU or the like is provided in the main body 62 of the positioning device 30, and a storage part 68 such as a semiconductor memory is connected to the control device 66. ing. The storage unit 68 stores an offset amount which is a difference between the actually required movement distance of the stopper 50 for each mold and the processing position dimension. Further, the control device 66 is connected to an input unit 70 for inputting data and a display unit 72 for displaying a liquid crystal panel or the like. As shown in FIG. 6, the input unit 70 is connected to the control device 66 by a curl cord 74, and is connected to the main body 62 or
It can be attached to any of the press machines 76.

Next, the method of use and the operation of the machined member positioning apparatus of this embodiment will be described. First, the positioning hole 40 of the setting gauge 42 is selected in accordance with the size of the die 11 to be attached, and the positioning pin 46 is fitted into the positioning hole 40 to set the setting gauge 42.
Determine the amount of protrusion. Then, the engaging member 38 is engaged with the engaged member 36 of the die mount 10. After that, the flange 24 at one end of the lower mold plate 12 is brought into contact with the tip of the setting gauge 42 to position the lower mold plate 12. Then, the lower mold plate 1 of the mold 11
2 is fixed to the die mount 10 with bolts 25. By changing the protrusion amount of the setting gauge 42, the press center can be set at a substantially constant position for the molds 11 of various sizes.

Thereafter, as shown in the flow chart of FIG. 7, when the power is first turned on, the stopper 50 is returned to a predetermined origin position by the drive motor 56 under the control of the control device 66. Then, from the input unit 70, the number of the current die 11 for performing a predetermined machining and the data of the machining position are input. For the processing position data, the processing position dimension, which is the distance from the tip of the processing member 48 to the center position of the portion to be processed, may be directly input. Then, when the offset amount, which is the difference between the actually required moving distance of the stopper 50 of the mold 11 and the processing position dimension, is accurately stored in the storage unit 68, that is, the use of the mold is the second time. When the offset amount at the time of first use is stored as data, or when the offset amount measured accurately in advance is input, this offset amount is read from the storage unit 68, and the input machining position and offset amount are read. From this, the control device 66 calculates the stop position of the stopper. After this,
When the start button of the input section 70 is pressed, the stopper 50
Moves to the position obtained by the calculation and stops. After the position of the stopper 50 is set, the press working is continuously performed thereafter.

If the die 11 is used for the first time and the offset amount data is stored in the storage unit 68 as test data at the time of shipment, or for other reasons, the storage unit 68 is used.
If you do not have accurate data on the offset amount for that mold,
As shown in FIG. 7, the working member 48 is trial-stripped.
As a result of the trial shot, as shown in FIG. 4, the deviation of the machining position is measured, and the error α of the actual machining position dimension L ₁ with respect to the desired machining position dimension L is input to the control device 66. And
The controller 66 corrects the offset amount used for the calculation before the trial hitting, that is, the test data or the erroneous value by the error α, and when the start button is pressed again, the stopper position is corrected. The offset amount after correcting the stopper position is stored in the storage unit 68 together with the die number as the offset amount of the die 11.

According to the processing member positioning method and apparatus of this embodiment, even if the size of the mold 11 is changed by the setting gauge 42, the relative origin position of the stopper 50 can be made approximately constant. The stopper 50 can be easily positioned. Moreover, the mold 11
The offset amount for each is stored in the storage unit 68 in advance, and the mold 1
Only by inputting the number 1 and the processing position, the position of the stopper 50 is automatically set in consideration of the offset amount.
Furthermore, even if an error is found in the offset amount, the offset amount can be updated to the corrected value, and when performing the next machining, the machining can be started quickly with the correct offset amount. Work efficiency can be greatly improved. Further, the offset amount can include all errors such as the mounting error of the mold 11 and the origin position of the stopper 50, and the setting gauge 42 can be easily projected by corresponding to the mold 11. Accurate processing is possible.

Further, since the stopper 50 is provided separately from the press machine, the vibration during pressing is generated by the stopper 50.
The position of the stopper 50 does not change during use. Further, it can be freely moved by the casters 64, and can be used for positioning the processing position of another machine.

The machined member positioning device of the present invention is
It can be used for various processing devices such as a drilling machine other than a press, and the type and shape of the processed member does not matter. Further, the corresponding mold number may be automatically input to the control device in conjunction with the positioning of the corresponding mold by the setting gauge. In addition, the offset amount includes a mounting error, and includes an error of a stopper and a connecting device in addition to the deviation of the center position of the mold.

[0019]

The working member positioning method and device of the present invention sets the difference between the actually required movement distance from the origin position of the stopper and the working dimension position of the working member as an offset amount to process the working member. Since the position is adjusted, it is not necessary to adjust the origin position of the processing device and its mounting base, and the position can be adjusted as an offset amount, including errors in the origin position of the stopper, and accurate positioning can be performed easily. Is something that can be done. Further, by storing the offset amount for each processing device, accurate positioning can be automatically performed.
