摘要： PROBLEM TO BE SOLVED: To reduce the oscillation of a car by integrating a rail, and substituting parts working accuracy for space accuracy and parallelism accuracy of a vertical guide surface engaged with a roller or a guide shoe. SOLUTION: A guide mechanism of a car 70 is formed of a rail unit 3, which is formed of a rail 1 and a rail bracket 2, and twelve rollers 41-52 rotatively supported on a roller bracket 71, which is provided in the car 70, freely to be rotated and engaged with the rail 1. With this structure, since surfaces 1a, 1d and 1b, 1e of the rail 1 have the predetermined parallelism, oscillation of the car in the direction Y and rotation thereof in axes X, Z are restricted. The rollers 49, 50 and 51, 52 pinch the surfaces 1c, 1f of the rail 1. Since the surfaces 1c, 1f have the predetermined parallelism, oscillation of the car in the direction A and rotation thereof in the axis Y are restricted.

摘要： PURPOSE:To enable the automatic deposition of a packing, by melting an end face in the state of the position of a magnet inserted into a packing member being set at the specified position, depositing the melted end face with its abutting corresponding to a preset melting allowance. CONSTITUTION:A packing member 101 is held by a packing moving means hand 21, held with its inputting onto packing hold fixing means 17a, 17b, and the melting allowances 66 at the packing member both ends are set in an arrow mark direction. A fin part fixture is then performed by actuating a fin part fixing cylinder 85. The packing member is thus fixed. However, a magnet 2 is not fixed. The maget position detection/alignment is then performed by separating the packing moving means hand 21. A hot plate 4 is then moved between the end faces of a packing member 101 placed opposite each other, the melting is performed in a non-contact state, and a pressurizing joint is performed by the movement in an arrow mark direction by a two directional pressurizing means. A deposition residue is not sticked to a melting means, the need for removing the residue is eliminated, because the deposition is performed with its melting with non-contact to a heating means, also the gas generated with the residue being burnt can be reduced drastically.

摘要： PURPOSE:To contrive to eliminate a pressure drop due to the resistance of a piping at the time of blow-off gas by a method wherein a tank part capable of being filled with the high-pressure gas is provided in the vicinity of a nozzle outlet and at the same time, a shutter mechanism to open and shut the nozzle outlet is provided in the vicinity of the nozzle outlet. CONSTITUTION:A tank part 1 capable of being filled with high-pressure gas and a rotating shutter part 5 to open and shut a nozzle opening part 3 are provided in the vicinity of the opening part 3. The opening part 3 is normally shut by the shutter part 5 and is opened only at the time of injection of the high-pressure gas. By designing in such a way, even though a piping on the way for the gas is long, the gas can be kept filling the tank part 1 at a pressure identical with its initial pressure and when the shutter part 5 is opened, a solder in through holes in a board 10 can be blown off at a high pressure.

摘要： PURPOSE:To enable a door packing to be welded at all times in the same condition in a grasped and fixed state even it may have dispersion in its outer dimension by sucking air from a packing insertion hole by a vacuum suction mechanism through an air tube at the time when the packing is set thereon. CONSTITUTION:When a jig cover 13 and jig holder 14 are assembled, they are designed to be formed with a packing insertion hole 9 therein, in which a packing 1 can be accommodated in the packing insertion hole 9. An air chuck groove 10 is provided on the side surface of the packing insertion hole 9, and as the packing is inserted thereinto as shown in the dotted lines of Figure, air is sucked from the air suction groove of side surface of the packing insertion hole by a vacuum suction mechanism F via a nipple 7 and air tube 12. As a result, the packing 1 made of a flexible material is chucked by an air chuck groove, and results in according to throats 1, 2, 8a, 8b of the packing insertion hole at all times by adsorptive force even in the case of being dispersed in the packing configuration, thereby performing the positional fixation of an end surface of the packing 1.

摘要： PURPOSE:To make improvements in productivity in making deburring work performable simultaneously with another work by installing a deburring means, consisting of a burr cutting part, on an abutting surface of each jig block forming a packing inserting hole on the inner circumferential surface at the time of assembling. CONSTITUTION:Jig blocks 21a, 21b divided into plural pieces are solidly assembled by a split assembling means and formed into a packing holding fixture, and then a packing inserting hole 22 is formed on the inner circumferential surface. Packing 1 is inserted into this hole 22, pressing a position where a magnet is inserted into the packing 1, thus this packing 1 is fixed. Next, after melting each end face of two pieces of the packing 1 with a heating plate, a pair of packing holding fixtures are moved inward, and when these ends of the packing are pressed and welded, each burr 5a being produced at both ends of this weld is cut off by a burr cutting part 25 of a deburring means being projected from an abutting surface between the jig blocks 21a, 21b in a state of being held between the abutting surfaces of these jig blocks 21a, 21b.

摘要： PURPOSE:To make it possible to remove uniformly a solder in a multitude of through holes in a short time by a method wherein the title device is provided with a driving means moving horizontally a nozzle for spraying hot air, an upper shroud frame enabling the movement of the nozzle in its interior and a lower shroud frame provided with exhaust means. CONSTITUTION:A nozzle 11 is mounted on a block 16, which is slidingly guided by a sliding guide 15 in its horizontal direction, facing downward its point to perform a reciprocating motion within a prescribed range in an upper shroud frame 9 by a horizontally driving motor 14, sliding ropes 12 and a pulley 13. Moreover, a lower shroud frame 24 held on an elevating actuator 25 is installed under a substrate 22: this frame 24 has a heating means 26 like an electric heater for heating the substrate 22 in a non-contact state in its interior and is provided with exhaust hoses 27 coupled with an exhaust pump as exhaust means. Thereby, a remaining solder in a multitude of through holes 23 covering a wide range in the substrate 22 can be removed in a short time without damaging the substrate 22.
