Description

[Detailed Description of the Invention] Moku Komei is involved in the method of measuring the tightening torque of bolts, and more specifically, by making a one-to-one correspondence between the position of the bolt on the object to be constructed (for example, Kazuhiro Group @) and the tightening torque. This invention relates to a method for measuring bolt tightening torque that can be displayed as a list.

When calculating the tightening torque of a bolt that is joined to a bolt or an ientm object, the tightening torque [
Record the sampling inspection method used for measurement and the measured tightening torque values of the marked bolts and nuts, and based on the curves, draw a group of bolts and nuts and create a data table for the tightening torque journal. The h method section to create is adopted, but 1g
There is a problem with the H method of tI arrival (YU!!R), which requires the presence of a member of the staff, and although the latter can omit the witnessing, it not only requires a great deal of effort to draw and tabulate. There was a risk that there would be m errors in the drafting and plotting, and the points on the paper inspection were the same as on the top of the mahjong force.

The present invention is an attempt to solve the problem of clay, and it is a pleasure to start pressing by using a nut runner to attach a nut to the bolt inserted into the kamimura house. Arrogant, Nanotora, and Boruto and Natsu, who are already crazy, are investigated by Racer 7c → Directly, and the location of Porto is 1.
The distance and angle are measured, and this one distance and angle measurement data is processed by a program pre-installed in the T-Yu Processing Scissors to determine the bolt position, while the bolt tightening torque value is calculated using the Nanotra>Light.・
Polarizes the light into the ``Dan''-da in the ``-i processing scissors, stores the position of the bolt and the threading torque value in 1 switch 1 via the T-ta processing edge straight; The bolt whose waiting value is to display and the purpose of non-invention are (1) wlA#
1f1v/J etc., the position of each bolt and nut in the NAND group is made to correspond one-to-one with the tightening torque value of the bolt in a list. 2) The goal is to reduce the need for the staff to be present, and the labor involved in plotting and plotting, as well as improving accuracy by eliminating the need for plotting and plotting.

The following is an example fr of the present invention: One circle of the turtle is illuminated with a gun.

In Figures 1 and 2, 1 is a steel-ttS or ill plate, 2 is a joint plate for joining one plate 1, and a bolt 3 is inserted into this joint. Then each bolt 3
A nut 4 is screwed into the . The nut runner 5 is used to tighten the nut 4 on the workpiece as described above.

The nut runners 5 are electrically connected to the data processing device 16, and the nut runners 5
is detected, data processing tilt1 starts with -
On the other hand, when the suppression light ends, NatsuTrunner 5 sends a message to 4.
The 4-inch torque value is detected and the m output data b is sent to a torque recorder built into the T-coupler 6. There is a suction disk 7 at a predetermined position on the I11 plate 1 above.
A laser source sweeping device 8 is installed via the laser source. This laser beam sweep mark ll [8 is a circular movement mechanism, heem N originator 9, is arranged in the rotation side mechanism at a height equal to that of the neck 1% 5a of the above-mentioned nut runner 5, As shown in Fig. 3, the angle of the foot is rotated between the angles of the foot through the forward and reverse angles of 0° and 0°, and the beam irradiates t9 Dl.

When the pillar is drawn, the laser beam 11 reflected by the laser light reflecting plate 12 housed in the neck 5a of the nut runner 5.
or re-enters the beam irradiation t9, the rape beam 1
Measure the bulge from the laser beam sweep device 8 to the bolt 3 based on the time from the firing of 1 to the tan incidence, and measure the bulge from the laser beam sweep device 8 to the bolt 3
From the rotation angle, the laser pulling device 8 and the bolt 3 are moved.
! It has a function of calculating the angle between L- and an arbitrary straight line added in advance.

The above-mentioned laser beam sweep edge 8 is also electrically connected to the T-wave processing straight line 6, and the data processing straight line 6 is installed from the nut runner 5. When received, the data processing edge v
Starting from t6 to Lep-9 return to 8 (while the m-C is on its way, when the laser beam sweep tsl:a reaches 0 for the distance measurement and angle measurement mentioned above, the distance measurement and -circumference data d The button can be pressed to the T-event processing device 6.

The pressing torque of the bolt 3 using the lever is measured in the following manner. First, operate the switch B on the handle 5b of the nut runner 5, which is attached to the nut 4, to start the nut runner 5 and start the nano z'f: ground rotation. Natsu 4 III! When antagonism occurs during the rotation, the nut runner 5 recognizes this as the start of pressing, and outputs the tightening start mVa to 1-Yudokoro Shiomasa Nao 6. To push! @The data processing re-reading 6 which received the start 1d No. a goes to the laser source return device [8 to activate Igvct-almost (1.

Activate the forward/reverse motor 10, measure the distance, and calculate the minus angle in t.
When photons are used for distance measurement and imaging, the laser beam 11 is started and the rotation of the JIE rotation motor 10 is stopped, and distance measurement and angle data d are transmitted to the data processing unit 6.

During the angle measurement operation 5, the nut runner 5 is tightened at a distance of 51Il by the laser source sweep straight line 8, and when the operation is completed and the compression is completed, at the same time as the tightening torque, the tightening torque is Detects the torque and sends Fushiyama T-ta b to the torque recorder.

T-Yudokoronbei VIt6 is the above-mentioned -Sho J] Tai-oki, -U/S-controlling force, laser beam sweep reading direct 8, distance measurement, angle measurement T-ta d'fi: When the construction T-ta b related to the tightening torque is received from the at-runner 5, it is processed using the distance measurement and angle measurement data a by the program installed in the driver's control, and then tightened by the lumped nut runner. The position of bolt 3 is 1'.

For example, the seat of Cartesian coordinates! 11 position and self-indexed T, the shaft torque value of the bolt 3 is successively output from the torque recorder, and the position of the bolt 3 corresponds to the mri torque wax in a one-to-one relationship, and magnetic tape warping is performed.] Ru. The table may be printed out on a soft paper sheet 15 in the data processing device 6.

To return part of the above to Holt 3ゎYohhis/)4t#, at the end of the tightening operation and at 10'', the bolt tightening torque value T-Y corresponds to the position of Holt 3. One-on-one correspondence with att. The T-Yu, which I remembered in my memory, uses a large converter to make a convenient T-ru for the nest 11i #' of the sister N7'-Yu of a large number of joints. - In the above practical example, the sweep of the laser beam 11 was achieved by rotating the beam control tube 9 with the turning motor 10, or by installing a counter-sweep in the optical path of the laser beam at the rotation point. It is also possible to sweep the mackerel by rotating it in a reverse rotation mode.

As explained above, the present invention utilizes tightening torque data measured by a nuts run, distance measurement using a laser beam sweep device,
Process the T-Y of the Holt position determined by angle measurement using the T-Y processing, and set the Holt position and the torque value with #a to 1.
< (2111) because of the relationship 1, it is possible to display the position of each bolt and nut in a group of bolts and nuts that connect a workpiece such as a steel structure. There is a young fruit that can list the bolt tightening 1 and T torque values, and it also saves the labor of the bean amount, drawing, and tabulation of the screwdriver, and prevents the contamination of the screws. Since the distance measurement is effective for each percentage, the effect of increasing the accuracy of the metal plate is also obvious.
