2. Description of the Related Art An inner cylinder and an outer cylinder made of metal are connected concentrically via a cylindrical vibration isolator, and an outer cylinder is attached to a vibration source side and an inner cylinder is attached to a vibration receiving side. There are vibration isolation structures used.

As a method of manufacturing such a vibration-proof structure, Japanese Patent Publication No. 59-19018 discloses a method of press-fitting a vibration-proof material formed by vulcanization between a metal outer cylinder and an inner cylinder coated with an adhesive. A method of manufacturing a vibration-proof structure in which an unbonded vibration-proof structure is assembled, at least one of the outer cylinder and the inner cylinder is heated by an electromagnetic induction heating device, and the vibration-proof material is bonded to the outer cylinder and / or the inner cylinder. Is disclosed, whereby only the metal part constituting the outer cylinder and the like generates heat in a short time, and only the surface part of the adhesive and the vibration isolator in contact with the metal part is locally heated. Therefore, it is described that the anti-vibration material can be bonded to the outer cylinder and / or the inner cylinder in a very short time, and that the anti-vibration material can be prevented from being deteriorated and the durability can be improved. .

In order to save energy by raising only the temperature of a necessary portion, a work coil for electromagnetic induction heating (hereinafter referred to as a work coil) is provided on the inner peripheral surface of the outer cylinder or the outer peripheral surface of the inner cylinder, which is the surface to be bonded to the vibration isolator. There is also a method in which the temperature is raised by bringing a “work coil” into close proximity, and the heated surface to be bonded is brought into pressure contact with a vibration-proof material coated with a thermosetting resin type adhesive.

[0005]

However, in the case of such a method, the temperature rises only in the vicinity of the surface to be bonded of the outer cylinder or the inner cylinder, and since metal generally has a high thermal conductivity, the rate of temperature decrease is high. Is fast, it is necessary to raise the temperature of the bonded surface of the outer cylinder or inner cylinder and integrate it with the vibration isolator in a short time.
Sufficient adhesive strength cannot be obtained between the outer cylinder or the inner cylinder and the vibration isolator. In addition, if the heating temperature is increased, it is not possible to achieve the intended purpose of high reliability of bonding and energy saving due to local overheating.

The present invention has been made in view of the above circumstances, and has as its object to raise the temperature by bringing a work coil close to a surface to be bonded of an outer cylinder or an inner cylinder, thereby increasing the temperature in a short time. An object of the present invention is to provide an apparatus for manufacturing a vibration-proof structure that can be bonded and integrated with a vibration-proof material.

[0007]

According to the present invention, a work coil, an outer cylinder holding section or an inner cylinder holding section, and a vibration isolator holding section are arranged in a straight line, and the outer coil or the inner tube heated by the work coil is arranged. The cylinder is moved to the vibration isolating material holding portion in a short time to be bonded and integrated with the vibration isolating material.

Specifically, the invention of the present application is an apparatus for manufacturing an anti-vibration structure in which a metal inner cylinder and an outer cylinder are concentrically connected via a cylindrical anti-vibration material, An outer cylinder holding portion that holds the outer cylinder and moves within a predetermined range along the central axis of the held outer cylinder; and an outer cylinder that is provided at one end of the moving range of the outer cylinder holding portion and holds the outer cylinder. An inner peripheral surface of the outer cylinder held by the outer cylinder holding portion, which is disposed so as to be surrounded by the outer cylinder held by the outer cylinder holding portion when the cylinder holding portion moves to one end of the movement range. An electromagnetic induction heating work coil for heating
When the outer cylinder holding part provided at the other end of the moving range of the outer cylinder holding part and holding the outer cylinder whose inner peripheral surface is heated by the work coil for electromagnetic induction heating moves to the other end of the moving range. A vibration-proof material holding portion for detachably holding a vibration-proof material having a thermosetting resin-type adhesive applied to an outer peripheral surface externally fitted to the outer cylinder held by the outer cylinder holding portion. Holding the outer cylinder with the outer cylinder holding part, moving the outer cylinder holding part toward the electromagnetic induction heating work coil, and using the outer cylinder held by the outer cylinder holding part for the electromagnetic induction heating. Surrounding the work coil,
After the inner peripheral surface of the outer cylinder is heated by the electromagnetic induction heating work coil, the outer cylinder holding portion is moved toward the vibration isolating material holding portion, and the inner peripheral surface is held by the outer cylinder holding portion. The heated outer cylinder is characterized in that the outer cylinder is held by the vibration-proof material holding portion and is fitted to the vibration-proof material having a thermosetting resin-type adhesive applied to the outer peripheral surface.

According to the above construction, the work coil, the outer cylinder holding portion, and the vibration isolating material holding portion are arranged in a straight line, and the outer cylinder holding portion is in alignment with the work coil position and the vibration isolating material holding portion. The outer cylinder held by the outer cylinder holding portion surrounds the work coil when it is at the work coil position, and the outer cylinder when it is at the vibration isolator holding position portion. Since the outer cylinder held by the holding section is configured so that the vibration isolator held by the vibration isolator holding section is externally fitted, the inner peripheral surface of the outer cylinder is heated by electromagnetic induction at the work coil position. Immediately after that, by moving the outer cylinder holding portion toward the vibration isolator holding portion, the outer cylinder whose inner peripheral surface is in a high temperature state can be externally fitted to the vibration isolator held by the vibration isolator holding portion. Can be. In other words, the outer cylinder holding section only needs to move back and forth over the shortest distance between the work coil and the vibration isolating material holding section, and there is no useless operation. It is allowed to heat and it can be bonded and integrated with the vibration damping material in a short time.

The invention of the present application is also effective in the case where the inner cylinder is bonded and integrated with the vibration damping material. In this case, a work coil is formed so that the inner cylinder can be inserted, and the work coil is used. After heating the outer peripheral surface of the inner cylinder, the heated inner cylinder is held in the vibration isolator holding section and is fitted inside the vibration isolator coated with the thermosetting resin type adhesive on the inner peripheral surface. do it.

Another invention of the present application is an apparatus for manufacturing a vibration isolating structure in which a metal inner cylinder and an outer cylinder are concentrically connected via a cylindrical vibration isolator. An outer cylinder holding portion for holding the cylinder, a position provided on one extension of the central axis of the outer cylinder held by the outer cylinder holding portion, and a position to be inserted into the outer cylinder held by the outer cylinder holding portion; The inner peripheral surface of the outer cylinder held by the outer cylinder holding part when moved to a position retracted from the outer cylinder held by the outer cylinder holding part and moved to a position to be inserted into the outer cylinder. And a work coil for electromagnetic induction heating, which is provided on the other extension of the center axis of the outer cylinder held by the outer cylinder holding portion, and a thermosetting resin-type adhesive applied to the outer peripheral surface. Between the position where the vibration isolator is held inside the outer cylinder held by the outer cylinder holder and the position where the vibration isolator is released and retracted from the outer cylinder. And a vibration isolator holding portion for heating and adhering the vibration isolator to the inner peripheral surface of the outer cylinder when moving to a position where the vibration isolator is fitted inside the outer cylinder. Insert the work coil into the outer cylinder held by the outer cylinder holder,
After the inner peripheral surface of the outer cylinder was heated by the electromagnetic induction heating work coil, the thermosetting resin type adhesive was applied to the outer peripheral surface while retracting the electromagnetic induction heating work coil from the outer cylinder holding portion. It is characterized in that the vibration isolator is held by the outer cylinder holding portion and is fitted inside the outer cylinder whose inner peripheral surface is heated.

According to the above configuration, the work coil, the outer cylinder holding portion, and the vibration isolator holding portion are arranged in a straight line, and the work coil and the vibration isolator holding portion are both aligned with the outer cylinder holding portion. Can be moved between the position and the retracted position, and when the work coil is at the outer cylinder holding portion position, the work coil is inserted into the outer cylinder held by the outer cylinder holding portion,
When the vibration isolator holding portion is at the outer cylinder holding portion position, the vibration isolator held by the vibration isolator holding portion is fitted inside the outer cylinder held by the outer cylinder holding portion. So, after electromagnetic induction heating the inner peripheral surface of the outer cylinder by the work coil,
Immediately move the work coil away from the outer cylinder holding part and move the vibration isolator holding part toward the outer cylinder holding part. It can fit inside a certain outer cylinder. In other words, the work coil and the vibration isolator holding section need only move back and forth over the shortest distance from the outer cylinder holding section, and there is no useless operation. Therefore, the work coil is moved up close to the inner peripheral surface of the outer cylinder. It is allowed to heat and it can be bonded and integrated with the vibration damping material in a short time.

[0013] The other invention of the present application is also effective in the case where the inner cylinder is bonded and integrated with the vibration damping material. In this case, a work coil is formed so as to surround the inner cylinder, and the work coil is formed. After heating the outer peripheral surface of the inner cylinder, the vibration isolator held by the vibration isolator holding section and having the inner peripheral surface coated with a thermosetting resin-type adhesive is externally fitted to the heated inner cylinder. Configuration may be adopted.

In the case where the work coil and the vibration isolating material holding portion are arranged vertically above and below in a substantially vertical direction and the outer cylinder holding portion or the inner cylinder holding portion moves between them, at least the vibration isolating member is provided. When the outer cylinder is externally fitted or the inner cylinder is internally fitted to the vibration isolating material held by the material holding section, or the vibration isolating material held by the vibration isolating material holding section is internally fitted to the outer cylinder or externally fitted to the inner cylinder. In this case, it is preferable to provide a shielding means for shielding between the work coil and the vibration isolator holding portion. According to such a configuration, when the outer cylinder or the inner cylinder is mounted on the vibration isolator, the shielding means is used even if the thermosetting resin adhesive applied to the outer peripheral surface or the inner peripheral surface of the vibration isolator falls as droplets. Thus, the work coil is prevented from being contaminated by the droplet being dropped on the work coil. Examples of the shielding means include a shielding plate configured to be able to shield between the work coil and the vibration-proof material holding unit.

Further, when the outer cylinder is externally fitted to the vibration isolating material held by the vibration isolating material holding portion or when the inner cylinder is internally fitted, or when the vibration isolating material held by the vibration isolating material holding portion is fitted to the outer cylinder. When internally fitting into the inner cylinder or when externally fitting to the inner cylinder, one of the vibration-proof material and the outer cylinder or the inner cylinder held by the vibration-proof material holding portion is 0.2 to
It is preferable to be configured to move at a speed of 1.0 m / s to fit outside or inside. According to such a configuration, since the integration of the vibration isolator and the outer cylinder or the inner cylinder is performed in a biased state, the integration of the two can be reliably achieved against the resistance force. In addition to this, the cured state and the adhered state of the adhesive in the process are optimized. Here, when the relative speed is slower than 0.2 m / s, the curing of the adhesive starts during the outer fitting or the inner fitting, and the outer cylinder or the inner cylinder is bonded and fixed to a predetermined position of the vibration insulator. This is because, on the other hand, if the speed is higher than 1.0 m / s, uneven adhesion of the adhesive tends to occur. Therefore,
From these viewpoints, the range of the relative speed is 0.3 to 0.5.
More preferably, it is set to 8 m / s. Such speed control is preferably performed using a servomotor.
This is because control with higher speed and position accuracy can be performed than control using an air cylinder or a hydraulic cylinder and a limit switch.

Further, the apparatus for manufacturing a vibration isolating structure according to the invention of the present application or another invention of the present application provides a surface treatment for performing a chlorination treatment or the like for improving the adhesion of an adhesive to a vibration isolating material. The adhesive applying section for applying the thermosetting adhesive to the section and the vibration isolating material may be provided separately from the work coil. According to this configuration, the surface treatment section and the adhesive application section are integrated into the manufacturing apparatus of the vibration isolating structure, so that the surface treatment time, the adhesive application time, the electromagnetic induction heating time of the outer cylinder or the inner cylinder, and the prevention of the electromagnetic wave. The cycle time can be optimized by appropriately setting the time for integrating the vibration material with the outer cylinder or the inner cylinder and the cooling time, and the productivity can be improved. In addition, since the surface treatment section and the adhesive application section are provided separately from the work coil, the adhesive adheres to the work coil and is contaminated, or the adhesive is ignited, burned, or exploded by the heat of electromagnetic induction heating. There is no danger of doing.

[0017]

As described above, according to the invention of the present application, the outer cylinder holding portion only needs to move back and forth between the work coil and the vibration isolating material holding portion. According to another aspect of the invention, the work coil and the vibration-proof material holding portion are
You only have to go back and forth the shortest distance to the outer cylinder holding part,
Since there is no useless operation, the temperature of the work coil can be raised by bringing the work coil close to the inner peripheral surface of the outer cylinder, and it can be bonded and integrated with the vibration damping material in a short time.

-Preparation step- The outer peripheral surfaces of metal tubes (iron, aluminum, tin, nickel, or the like, or alloys thereof) are fixed to both ends of a metal pipe, and a thermosetting resin paint is applied to the surfaces. A baking coating film is formed by exposing it to a high temperature
A member in which the outer cylinders 1 and 1 are joined at both ends is created. here,
Decomposition temperature of baked coating film is 230 ° C for thermosetting resin paint
The following epoxy resin coating for cationic electrodeposition coating is used. The decomposition temperature of the baked coating film means a temperature above which the baked coating film is degraded and decomposed, softened and peeled off or foamed and carbonized, so that the function of imparting corrosion resistance cannot be satisfied.

Decomposition temperature of baked coating film is 230 ° C for thermosetting resin paint
The following epoxy resin coating for cationic electrodeposition coating is used. The decomposition temperature of the baked coating film means a temperature above which the baked coating film is degraded and decomposed, softened and peeled off or foamed and carbonized, so that the function of imparting corrosion resistance cannot be satisfied. A similar coating process is performed on a metal cylinder having a smaller diameter than the outer cylinder 1 to form the inner cylinder 2.

A molding composition is filled with a rubber composition or a urethane foam composition or the like mainly composed of a diene rubber such as a nitrile rubber or a diene rubber as a main component, and heated in a molding die. The thick cylindrical vibration-proof material 3 integrated into the state is vulcanized. The anti-vibration material 3 in which the inner cylinder 2 is integrally formed in an in-fit state is transferred to a surface treatment part, where a sodium hypochlorite solution or a chlorinated cyanuric acid solution is applied to the outer peripheral surface of the anti-vibration material 3 to perform surface treatment. To improve the adhesiveness of the adhesive. Then, it is transferred to the adhesive application section, and the gelation start temperature is 100 ° C. or more and the curing temperature is 180 ° C.

The oscillator connected to the work coil 221 is set to 1
Oscillation starts at an oscillation frequency of 0 to 300 kHz (SB
4) Stop the oscillation continuously for 1 to 10 seconds (SB
5). At this time, the inner peripheral surface of the outer cylinder 1 is higher than the curing temperature of the resin adhesive used for bonding to the vibration isolator 3 and lower than the decomposition temperature of the baked coating film made of the thermosetting resin paint. The temperature is raised from a temperature (180 to 230 ° C.) to a gel-like temperature range where the resin adhesive becomes a gel state.

Since the vibration isolator 3 held by the vibration isolator holder 231 is internally fitted to the outer cylinder 1 held by the outer cylinder holder 211, the work coil 221 is used to hold the outer cylinder 1. Immediately after the inner peripheral surface is heated by electromagnetic induction, the work coil 221 is moved away from the outer cylinder holder 211 and the vibration isolator holder 23
By moving 1 toward the outer cylinder holding section 211, the vibration isolator 3 held by the vibration isolator holding section 231 can be fitted inside the outer cylinder 1 whose inner peripheral surface is in a high temperature state.
