In the rivet caulking device, the rivet caulking device is configured to press-fit the rivet into the head and then apply caulking deformation to the head. A first signal indicator that is activated when detecting the first position of the 20 workpieces at intervals approximately equal to the height dimension before deformation is connected to an indicator that compares and displays the press-fitting load of the belly button with the appropriate load. In addition, a second fern indicator 25 which is activated when the second detector detects the height dimension after caulking deformation of the head is connected to the drive source of the head in order to stop the forward movement of the head. .
本発明実施の１例を別紙図面に付説明する。An example of implementing the present invention will be explained with reference to the attached drawings.
図面で１はリベットを示し、該リベット１は膨大する頭

は該リベット１が圧入されて該頭部１ａがかしめ変形に
備−Ｃに−えられる状態、第２図は該頭部１ａのかしめ
変形後の状態、即ち製品状態を示す。In the drawings, reference numeral 1 indicates a rivet, and the rivet 1 has an enlarged head 1a.The head 1a has a planned size of, for example, 1.7 mm before deformation and a planned size after deformation of caulking. For example, let it be 1.5-. In the drawings, reference numeral 2 indicates a workpiece, and the workpiece 2 is made up of a thin plate 2b placed on a workpiece body 2a, and is provided with a rivet hole 2c. The thin plate 2b
They were connected to each other by rivets. FIG. 1 shows the state in which the rivet 1 is press-fitted and the head 1a is prepared for caulking deformation, and FIG. 2 shows the state after the caulking deformation of the head 1a, that is, the product state.
該りベント１は例えば第５図に明示するようにその背面
の圧入ベンド４により押圧されて前記した圧入と、次で
前記したかしめ変形とを与えられるもので、該ヘッド４

うにした。For example, as clearly shown in FIG. 5, the bending vent 1 is pressed by a press-fitting bend 4 on the back side thereof, and is subjected to the above-mentioned press-fitting and then the above-mentioned caulking deformation, and the head 4
For example, as shown in FIGS. 3 and 4, the type is fixed to the lower surface of the ram 7 above the workpiece mount 6 on the machine base 5,
The ram 7 is screwed onto a feed spindle 9 that is linked to a motor 8, and is moved up and down as the spindle 9 rotates forward and backward.
該ヘッド４には、かしめ位置測定の第１検出子１０とか
しめ高さ測定の第２検出子１１とを備え、これら検出子

ている。The head 4 is equipped with a first detector 10 for measuring the caulking position and a second detector 11 for measuring the caulking height. A first signal indicator 12 and a second signal indicator 13 whose height display is set to zero are connected via master dimensions of 1.7 Tmn and 1.5 m.

その他の表示器を備えるものとする。Therefore, when the bend 4 is rising, each signal indicator 12, 13 is free and its pointer indicates the other and does not generate a signal. When the pointer approaches and matches the scale set to zero, the switch mechanism inside the indicator 12 activates and generates a signal, which is transmitted to the strain meter 14 provided in the head 4 and converted into an electrical output. Convert and display the press-fitting load at that moment on display 1.
Further, when the pointer of the second signal indicator 13 matches the scale set to zero via the second detector 11, the switch mechanism inside the indicator 13 operates to generate a ζ movement signal to control the feed motor of the ram 7. Reverse 8 and ram 7
was made to rise. Although not shown, the display 15
has two fixed pointers that indicate the allowable range of press-fitting load and a movable pointer that indicates the actual press-fitting load.When the signal from the first signal indicator 5 and 12 is received, the movable pointer swings to indicate that it is within the allowable range. If the input value is within the expected range, the good product lamp will light up, and if it is outside the range, the defective product lamp will light up and the buzzer will sound. shall be equipped with a lamp or other indicator.

第２図示の状態となり製品を得られる。To explain its operation, the workpiece 2 is mounted on the workpiece mount 6 and the riveting tool 1 is applied to it, and then the press-fitting action 7 is activated to apply downward pressure to the riveting tool 1. , accordingly, the bent vent 1 is connected to the workpiece 2.
The head 1a is gradually press-fitted into the rivet hole 2c to take the state shown in the first figure, and then the head 1a is caulked and deformed to take the state shown in the second figure to obtain the product.

する。Although this point is not particularly different from the conventional one, according to the present invention, the heel 4 is in the first position, that is, between the head part 4 and the workpiece 2.
When it reaches the forward position where there is a gap approximately equal to the height dimension before caulking deformation a, the first detector 10 detects this and outputs an output to the first signal indicator 12, and the bend The press-fitting load of 4 is measured and this is displayed on display 1.
5. If the measured value is not within the expected range, this is known due to a defective lamp or the like, so stop the work at this stage, remove the work 2, and move on to the next work 2. Replace it and do almost the same work. If it is within the planned range, the work is continued, and then the second
When the position is reached, that is, the forward position where there is a gap between the head 1a and the workpiece 2 that is approximately equal to the planned dimension after caulking deformation, this is detected by the second detector 11 and an electric signal is sent to the two-signal indicator 13. occurs, and the hesode 4 is stopped from advancing. In this case, if the indicator 13 does not produce a signal, known as a lamp or the like, the operation is immediately stopped and the product is treated as rejected. That is, in this case, the head 1
a is not within the predetermined height dimension, and thus the product is rejected in the height dimension. In this way, according to the present invention, the press-fitting load is measured at the first position of the press-fitting head and the height is measured at the second position in sequence, eliminating the need for post-inspection of the product and improving workability. It has a significantly improved effect.
