Abstract: Actual coordinate system data is acquired on the basis of a coordinate position at which a coordinate system generating tool attached to a robot is brought into proximity to, or contact to a coordinate system generating target of a coordinate system generating unit attached to a work piece positioning device. Simulation teaching data of a movement trajectory of a welding gun and design coordinate system data based on a design coordinate value of a coordinate system generating target are acquired by using a virtual model. After the actual coordinate system data is acquired into an information processing system, a coordinate position of the simulation teaching data is then moved to match the design coordinate system data with the actual coordinate system data.

Abstract: Provided is a device for assembling a fuel supply pipe of which a joint portion between a pipe body and a short cylindrical member has a high strength and which has high anti-corrosion performance. Specifically, while a laser beam in a defocused state is being emitted to impinge on an end portion of the pipe body that overlaps the short cylindrical member, the pipe body and the short cylindrical member are rotated through one complete turn relative to the laser beam, thereby melting the entire periphery of the end portion. While the laser beam in a defocused state is being emitted to impinge on the melted end portion, the pipe body and the short cylindrical member are rotated through at least one further complete turn, thereby joining by welding the end portion to the outer periphery of the short cylindrical member.

Abstract: Provided is a press apparatus which ensures high production efficiency and has less chances of breakdown. Specifically, the press apparatus has a base placed on a floor, and a platform arranged over the base to face the base and move up and down. A lower die, on which a steel plate is to be placed, is fixed to the base. An upper die is fixed to the platform to press the plate against the lower die and turn it into an initially formed product through a downward movement of the platform, and to pressure-hold the initially formed product with the lower die. A machining die is supported on the platform to move up and down to machine the initially formed product and form a final product by moving down while pressure-holding the initially formed product.

A primary forming step of obtaining a primary formed product by plastically working a heated steel sheet with a primary forming die set for a predetermined time period, a secondary forming step of machining the primary formed product with the secondary forming die set for a predetermined time period to obtain a secondary formed product, and a hardening step of allowing a cooling die set placed in a hydraulic press controlled by a servomotor to hold the secondary formed product under pressure for a longer time period than the time period of each of the primary and secondary forming steps to obtain a hardened final formed product are successively performed in sequence. The hardening step is performed independently without coordinating with the primary and secondary forming steps.

A welding robot is provided in a workpiece welded region. A control board outputs an operation signal to the rotating table such that the jigs respectively move into a workpiece set region and the workpiece welded region, and outputs an operation signal to the respective jigs such that the jig in the workpiece set region is inclined toward a side closer to the worker and the jig in the workpiece welded region is inclined according to welded parts of the workpieces.

Abstract: Fuel vapor is prevented from leaking to the outside during refueling, and even when an air space is formed in an upper portion of a fuel filler pipe, a diagnosis of leakage of fuel vapor can be performed with good accuracy. During refueling, fuel vapor is guided from a fuel tank 1 to a canister 3, and is absorbed by the canister 3. A change in the internal pressure of a fuel vapor path including the fuel tank 1, a fuel vapor pipe 4, and the canister 3 is detected by a pressure sensor 8, thereby performing a diagnosis of leakage of fuel vapor. An upper space 16 in the fuel tank 1 and an upper space 17 in a fuel filler pipe 2 communicate with each other through an airflow resistance pipe 12, and in order to restrict flow of fuel vapor from the fuel tank 1 through the airflow resistance pipe 12 into the fuel filler pipe 2 during refueling, the airflow resistance pipe 12 includes an orifice 13.

Abstract: An electrode inspection apparatus for spot welding is provided for precisely measuring diameters of a tip of an electrode without reducing availability ratio in a production line, and is particularly useful when inspecting a weld gun having electrodes with a narrow distance therebetween.
