A welding gun includes a proximity restricting mechanism that is provided between a shaft and a cover member in a manner to surround the shaft and to be displaceable relative to the shaft in an axial direction in accordance with expansion and contraction of the cover member, and that restricts the cover member from approaching too closely the shaft.

A connecting deviceof a towing vehicleincludes a connecting pin, a locking arm, and an actuator. The connecting pinis provided to be rotatable between a connection position where the connecting pinis brought into fitting engagement with a connecting plateof a wheeled platformand a disconnection position where the connecting pinis taken out of the fitting engagement with the connecting plate. The locking armis driven by the actuatorbetween a locking position where locking armis locked with the connecting pinsuch that the connecting pincannot rotate out of the connection position toward the disconnection position and an unlocking position where the connecting pinis unlocked in the connection position.

Connecting device and towing vehicle

A welding gun includes: a moving mechanism portion (ball screw mechanism) for moving a movable electrode back and forth; a motor that includes a rotor and drives the moving mechanism portion to move the movable electrode back and forth; and a brake mechanism that prevents rotation of the rotor during a braking operation, wherein the brake mechanism includes an annular brake disc that is attached to an outer peripheral surface of the rotor and rotates integrally with the rotor, and a clamping portion that prevents rotation of the brake disc by clamping the brake disc during the braking operation.

The guidepath includes: a magnet guide tape which carries S pole, and guides a carrier vehicle in a first direction by the S pole by being arranged on a floor so as to extend in the first direction; a magnet guide tape which carries S pole, and guides the carrier vehicle in a second direction by the S pole by being arranged on the floor so as to extend in a second direction which intersects the first direction; and a magnetic body tape which is arranged at a side of the magnet guide tape at a position above which a marker sensor passes upon the carrier vehicle being guided by the magnet guide tape, and suppresses N pole.

A tire mounting apparatus is constructed from a first working mechanism and a second working mechanism that are separate from each other. The first working mechanism is provided with a tire holding device for holding a tire and with a temporary tightening device for temporarily tightening nuts onto hub bolts to which the tire is mounted. The second working mechanism is provided with a final tightening device means for finally tightening the temporarily tightened nuts. The final tightening device includes two nut runners and an interval adjuster for adjusting an interval between the two nut runners.

Tire mounting apparatus

A tire mounting method is provided for automatically mounting a tire onto hub bolts of a motor vehicle. The method includes gripping the tire and temporarily tightening nuts on the hub bolts on which the tire has been placed with a first working mechanism. The nuts that have been temporarily tightened by the first working mechanism are fully tightened with a second working mechanism, which is disposed in association with a first mounting region on a front wheel side or on a rear wheel side of the motor vehicle. The nuts that have been temporarily tightened by the first working mechanism are fully tightened with a third working mechanism, which is disposed in association with a second mounting region on the rear wheel side or on the front wheel side of the motor vehicle.

Tire mounting method using a tire mounting device

Tire mounting method

A tire mounting method for automatically mounting tires onto hub bolts of a motor vehicle using a tire mounting device having a first working mechanism and a second working mechanism. The method includes feeding the motor vehicle intermittently so that hub bolts of a front wheel and hub bolts of a rear wheel are successively positioned in a tire mounting station. Tires are gripped by a tire gripping unit of the first working mechanism, and nuts are successively temporarily tightened onto hub bolts of front and rear wheels to which the tires are mounted. The nuts, which have been temporarily tightened, are then fully tightened using the second working mechanism.

According to the present invention, even during and immediately before a machining operation by a machining apparatus, it is possible to improve positioning control accuracy thereof and, as a result, machining accuracy thereof. A robotequipped with a machining toolperforms a moving operation to a target positionof a machining target workpieceand a machining operation on the machining target. A robot moving mechanismmoves the robotin parallel with the workpiecethat is being conveyed by a conveyance carriage. A robot control devicecontrols movement of the robot moving mechanismusing a detection result of a synchronizing sensorand carries out positioning control of the robotusing the detection result of a visual sensoror a synchronizing sensor

Machining system and method

An apparatusfor coupling a first memberand a second memberby a clip and a screw is constituted by member moving meansL,R for moving the second memberrelative to the first member, reaction force detecting meansL,R provided to the member moving meansL,R for detecting a press reaction force generated when the second memberis matched to the first member, clip fitting determining meansL,R for determining whether the clip is correctly fitted to a clip hole by reading the reaction force detected by the reaction force detecting meansL,R, and screw fastening meansfor fastening the screw when acceptable information is provided by the clip fitting determining meansL,R.
