伴う。 Conventionally, in this type of device, after the electrode of the resistance welding machine is brought into contact with the rotary blade, the rotary blade is generally driven to rotate continuously by a motor, but in order to miniaturize the device, this type of device does not use a motor as a motor. A relatively small one must be used, and if the rotary blade bites into the electrode at the start of grinding, it will be difficult to start the rotary blade, resulting in the inconvenience that the electrode cannot be reliably ground.

Each rotary blade 3 is inserted into each slit 7, and the rotary blade 3 is inserted radially outward. is biased radially inward by the spring 8 via the contact piece 9, and when the receiving seat 5 is sandwiched between the electrodes a, a from above and below, each rotary blade 3 is pressed against both electrodes with a predetermined pressing force. The electrodes a and each curved portion b of a are brought into contact with each other,
According to the rotation of each of the rotary blades 3 due to the rotation of the rotary disk 4, each of the rotary blades 3 is pressed by the spring 8 and comes into contact with the circumferential side of the catch seat 4 at a predetermined time while grinding the curled portion b. was advanced to the grinding position, and the grinding and shaping of both electrodes a, a was performed.

1a and keyed thereto, and the driving gear 10 is provided on the outer surface of the device main body 1.
It is connected via a one-way clutch 15 to a pinion 14 that meshes with a rack 13 that is reciprocated by 2, and thus, each time the rack 13 is reciprocated to the right in FIG.
In the system of 5→drive gear 10→driven gear 11, the rotary disk 4, and thus each rotary blade 3 supported thereon, is intermittently rotated counterclockwise in FIG. 2. In the drawing, reference numeral 16 designates the support member of the rack 13. Next, to explain the operation, even if the insertion of the electrode a into the electrode insertion portion 2 causes the rotary blade 3 to bite into the curved portion b, the rotary blade 3
The intermittent drive due to the forward movement of the cylinder 12 causes the electrode a to be smoothly activated by receiving a large rotational torque due to the pressing force from the cylinder 12, and the electrode a is reliably ground and shaped.
