(d) The crank pin 73 has reached the top dead center and the embossing A state in which the marking on the vehicle body 29 by the ring 6 has been completed is detected.

Next, the operation of this embodiment will be explained. When stamping the vehicle body number on the vehicle body 29, the movable body 1 is displaced and the pad 4 is brought into contact with the back of the vehicle body 29 at the part to be stamped. At this time, the vehicle body 29 is placed on a hanger (not shown), and there is a risk of the position shifting. is prevented.

A signal regarding the first digit of the vehicle body number is manually inputted to the character indicating means 90 of the control device C from a card reader (not shown). As a result, character data is inputted from the character designation means 90 to the angle designation means 91, and the character data is input to the angle designation means 91.
1, it is converted into angle data and input to the character selection driving means 7. Accordingly, in the character selection driving means 7, the power of the drive motor 44 is transmitted to the marking ring 6 without delay by the roller gear cam mechanism 45, and the desired marking 40 is moved to the position corresponding to the pad 4. At this time, the amount of angular displacement of the embossing ring 6 is detected by the encoder 51, and the embossing ring 6 is driven for angular displacement while checking whether the detected value matches the indicated value of the angle indicating means 91. encoder 51
The embossing ring 6 is driven for angular displacement while checking whether the data obtained by converting the detected angle into character data by the converter 93 matches the character data designated by the character designating means 90. Therefore, the desired marking 40 can be accurately placed at a position corresponding to the pad 4.

Next, the engraving motor 60 of the engraving drive means 8 is operated to move the housing 5 and the engraving ring 6 into the vehicle body 2.
9, the stamp 40 collides with the car body 29, and the - character is stamped 4. Moreover, the impact at this time is absorbed by the buffering means 31, so that the support arm lO, that is, the movable body l It doesn't convey much.

When the position detection means 81 detects that the embossing ring 6 has moved back slightly after the first digit has been stamped, the character selection drive means 7 is actuated to angularly displace the embossing ring 6, and the next digit is Stamp 40
moves to the position corresponding to the bet 4. Moreover, at the same time, the marking position changing means 2 is activated, the support arm 10 is extended, and the pad 4 is shifted to the marking position of the next digit.

When the housing 5 and the embossing ring 6 move forward again and the position detection means 81 detects that they have come just before embossing, it is confirmed whether or not the character selection operation of the embossing ring 6 has been completed. . As a result, if the character selection operation has been completed, the embossing ring 6 is further advanced to perform embossing, and if the character selection operation has not been completed, the operation of the embossing motor 60 is stopped and the character selection is performed. Terminate operation.

By sequentially repeating such operations, a multi-digit vehicle body number is stamped.

After the stamping is completed, when the position detection means 81 detects that the stamping ring 6 has retreated to the maximum rearward position, that is, that the crank pin 73 has reached the bottom dead center, the stamping motor 6 is activated.
0 is stopped and the movable body 1 is returned to its original position.

According to the invention described in claim (1), the first alignment means 92 may be omitted, and the angle is indicated while the encoder 51 as the first alignment means detects the angular displacement amount of the embossing ring 6. The operation of the character selection driving means 7 may be controlled so that the instruction amount of the means 91 and the detected value of the encoder 51 are matched.
