A component incorporation and liquid filling device of a liquid filled vibration isolating mount uses a relatively small liquid bath disposed above a fixedly held, upwardly facing body component, and when moved downwardly, an opening portion provided on a bottom portion thereof is assembled in a sealed state. Liquid supplied onto the bottom portion flows into the body component and is stored on the top of the bottom portion. Components are assembled to the body component in the liquid, and the liquid contained. The seal member is fitted to the opening portion by screwing means from the lower surface side. A notch for a screwing operation is provided on the upper surface of an outer circumferential body of the seal member whereby the screwing operation can be implemented from the upper surface side, thereby facilitating replacement of the seal member.

Component incorporation and liquid filling device of liquid filled vibration isolating mount

An improved apparatus for conducting the operation of incorporating components and filling liquid for the assembly of a liquid-sealed vibration-proof mount by sequential steps of: depressing a liquid tank disposed above a main components body held to be faced upwardly toward it, installing an aperture at a bottom of the tank to the main body hermetically, supplying liquid onto the bottom to flow the liquid inside the main body and to store it on the bottom, incorporating a partition and other components into the main body in the liquid stored when detecting a definite liquid level with a liquid level detector tube and simultaneously sealing liquid, followed by discharging of the liquid from the bottom and removal of the liquid tank from the main body, whereby the operation can be conducted efficiently without causing error operation and suspending by use of a liquid tank having a small volume. To that end, the liquid level detector tube has valve means suppressing pulsation of the liquid surface to the extent that the liquid level can be detected correctly.

Apparatus for incorporating components and filling liquid for liquid-sealed vibration-proof mount

The present invention provides, in assembling an anti-vibration device having an inner cylinder, an outer cylinder, a rubber elastic member joining them and an intermediate cylinder fitted to the outer cylinder and internally forming a liquid chamber, an assembling apparatus for caulking an end of the outer cylinder while suppressing the occurrence of buckling without causing cracks, breakage or the like. This assembling device has a press-fit device to press-fit an internal unit joined with the inner cylinder and the intermediate cylinder through a rubber elastic member to the outer cylinder within a liquid tank, a caulking device to caulk an end of the outer cylinder of an assembly completed in press-fitting, and transporting means to transport the assembly from the press fit device to the caulking device. The caulking device can perform caulking in two stages of caulking.

Apparatus for assembling an anti-vibration device

The present invention can weld two parts of component metal fitting constituting the parts as a welding apparatus used in manufacturing automotive parts such as a strut mount upon positioning and laminating. Furthermore, a welded part can be easily recovered to improve the operationality of welding. This welding apparatus has support tables to support two parts of component metal fitting. The support table has thereon a positioning pin provided standing in a position corresponding to the penetration holes possessed in the both parts of component metal fitting and a lower electrode to support the two parts of component metal fitting in their joining points. In a position further above thereof, an upper electrode is provided that is held vertically movable. The positioning pin in its upper end is made in a tapered form. The pin is supported elastically pressed down by spring means. Furthermore, urging means is provided to press down the pin against the spring means separately from the upper electrode. Due to pressing down of this urging means, the pin is pressed down from a state that the tapered upper end is positioned above the penetration hole of the parts of component metal fitting supported by the lower electrode. The pin and the penetration hole at its peripheral edge are to be disengaged.

Welding apparatus

The present invention provides a molding tool capable of forming a molding with a cylindrical core while ensuring the discharge of the air in the vicinity of an upper end portion and forming no end face burr. As the device for this molding tool, an upper mold and a lower mold , as can be clamped, are provided with insert dies and having fitting hole portions and at their centers. The lower fitting hole portion is provided with a support pin to be fitted in the cylindrical core thereby to retain the cylindrical core , and the upper fitting hole portion is provided with a core holder so that a cavity is formed around the outer circumference of the cylindrical core when in the clamped state, to charge the cavity with a molding material to be shaped. A seal ring is mounted in the fitting hole portion of the upper insert die to fit the outer circumference of the upper end portion of the cylindrical core while holding a slight air ventilation. The upper mold is provided with an injection hole for the molding material and a relief hole for the air and the molding material.

Molding tool for molding with cylindrical core

A slitter for steel belt including rotary blades for slitting a belt material including steel cords and topping rubber. The rotary blades include an upper blade and a lower blade having their circumferential portions slightly overlapped and in contact with each other. Sandwiching delivery members for delivering the belt material to the blades is installed either at both sides or one side of the rotary blades in the delivery direction of the belt material so that the belt material is slit in a sandwiched condition. The sandwiching members as well as the rotary blades may be automatically adjusted in position in the transverse direction of the belt material. A freely suspended curved portion of the belt material formed between a delivering device and the slitter may be so controlled as to keep the suspended amount constant.
