Description

[Detailed description of the invention] The present invention relates to a vibration-proof heat shield plate with a metal vibration-proof mount, in which a metal vibration-proof mount is integrally fixed to the mounting hole of the vibration-proof heat shield plate. The reason for this is to reduce the number of parts and improve installation workability.

Conventionally, as shown in FIGS. 1 and 2, a wire mesh tube made of thin metal wire is compressed, and the bosses 1a of a bossed ring 1 are fitted into the mounting holes 2a of a vibration-proof and heat-insulating plate 2 from below. , a ring 3 made of the same material and formed in the same manner is fitted onto the boss 1a from above, a washer 4 is placed on the upper surface, and the center hole 1b of the ring 1 with the boss is inserted into the thermal vibrator 50 at a predetermined position through the screw hole 5a. Fit the vibro into the center hole 1b, insert the pole 7 into the vibro from above, and screw it into the screw hole 5a to fix the heat shield plate to the thermal vibrator for vibration isolation. Although this device is known, it has the disadvantage that it requires a ring with a boss, a ring, a washer, and a bolt in addition to the vibration-proof heat shield plate, so it has a large number of parts, and the installation work is time-consuming and troublesome. Ta.

The present invention eliminates the drawbacks of the conventional method by fixing a metal vibration-proof mount to the mounting hole of a vibration-proof heat shield plate by caulking.

First, as shown in FIG. 3, a wire mesh cylinder 10 made of a knitted metal wire 10a is wound in an annular shape to form a ring body 11, and the ring body 11 is compressed to form a metal anti-vibration mount 12. .

The boss 12a of the metal anti-vibration mount 12 is connected to the anti-vibration heat shield plate 1.
3 from below, and the protruding portion is caulked and fixed together as shown in FIG. 5 by the caulking portion 12b.

Next, the cylindrical portion 15a of the collar 15 is fitted and fixed into the center hole to form a vibration-proof heat shield plate 16 with a metal vibration-proof mount.

When in use, as shown in FIG. 6, the thermal vibrating body 18 such as an engine
A vibration-proof heat shield plate 16 with a metal vibration-proof mount as shown in Fig. 5 is attached.
A bolt 17 is inserted into the metal vibration-proof mount 12 via a washer 19, and is screwed and fixed into the screw hole 18a of the thermal vibrator 17.

According to the present invention, the metal anti-vibration mount is fixed to the mounting hole of the anti-vibration heat shield plate by caulking, so the number of parts is small.
Installation work is easy.

A naori is not necessarily required.
