Description

Technical Field

[0001] The utility model relates to the field of sound insulation of machine tool equipment, in particular to a sound insulation device for a supercharger cylinder with a window. Background Art

[0002] When the machine tool equipment is in use, the air pressure of the machine tool equipment will fluctuate up and down. When the air pressure is relatively low, the machine tool equipment will alarm and stop. Adding a supercharger cylinder to the machine tool equipment can keep the air pressure at the value required by the machine tool equipment, effectively solving the problem of low air pressure. However, when the supercharger cylinder is working, there will be noise. After the noise is too loud, it will seriously affect the operator's work. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a sound insulation device for a supercharger cylinder with a window, which is beneficial to sound insulation of the supercharger cylinder.

[0004] To solve the above problems, a sound insulation device for a supercharger cylinder with a window is adopted, which includes:

[0005] A workbench, on which the supercharger cylinder is installed. When installing, the pressure gauge of the supercharger cylinder is adjusted to face upwards.

[0006] A sheet metal outer cover, which covers the periphery of the supercharger cylinder and is fixed on the workbench, and a hole for the wiring of the supercharger cylinder to pass through is opened on its side.

[0007] A sheet metal cover plate, which is fixedly covered on the sheet metal outer cover, and a window opening is opened in the middle thereof.

[0008] Sound insulation sponge, which is laid and fixed on the inner side of the sheet metal outer cover and the inner side of the sheet metal cover plate.

[0009] A transparent acrylic plate, which closes the window opening and is fixed around the window opening.

[0010] Adopting such a structure, the sheet metal outer cover and the sheet metal cover plate provide an attachment surface for the sound insulation sponge; the window opening and the transparent acrylic plate are convenient for observing the pressure gauge.

[0011] As a further improvement of the utility model, the sound insulation sponge laid on the inner side of the lower part of the sheet metal outer cover is closely attached to the first positioning angle steel. The first positioning angle steel is connected end to end to form a circle, and the first positioning angle steel is fixed on the workbench.

[0012] Adopting such a structure, the first positioning angle steel can prevent the sheet metal outer cover from shifting during installation.

[0013] As a further improvement of the utility model, a first filling hole is opened on the first positioning angle steel, and foamed polyurethane is injected through the first filling hole.

[0014] With such a structure, the foamed polyurethane is conducive to plugging leaks and preventing water seepage, and also has a sound absorption effect to seal the lower edge gap; the foamed polyurethane is formed by filling a polyurethane foam filler into a wet base surface.

[0015] As a further improvement of the present utility model, second positioning angle steels are welded around the bottom surface of the sheet metal cover plate. The second positioning angle steels pass through the sound insulation sponge laid on the bottom surface of the sheet metal cover plate. Second filling holes are opened on the second positioning angle steels, and foamed polyurethane is injected through the second filling holes.

[0016] With such a structure, the second positioning angle steels prevent deviation when installing the sheet metal cover plate, so as to improve the installation accuracy. The foamed polyurethane cooperates with the second positioning angle steels to fill the upper gap, plugging leaks and preventing water seepage.

[0017] As a further improvement of the present utility model, continuous grooves are provided on the inner side surface of the sound insulation sponge.

[0018] With such a structure, the foamed polyurethane is filled in the grooves of the sound insulation sponge, which is conducive to forming a concave-convex combination, preventing slippage and making the connection tight.

[0019] As a further improvement of the present utility model, the shape of the groove is a water droplet shape, with the inner part being large and the outer part being small.

[0020] With such a structure, the water droplet shape further improves the anti-slip effect.

[0021] As a further improvement of the present utility model, sleeves are also fixedly arranged around the hole. The sleeves are fixed on both the inner and outer sides of the sheet metal outer cover. The inner sleeve passes through the sound insulation sponge and is fixed. The sleeves are for the connection wires of the booster cylinder to pass through. Third filling holes are opened on the sleeves, and foamed polyurethane is injected.

[0022] With such a structure, the hole can also achieve effective plugging and sound insulation.

[0023] The present utility model is conducive to the sound insulation of the booster cylinder. Description of the Drawings
