Dustproof structure of machine tool

Abstract

The invention discloses a dustproof structure of a machine tool, which comprises a dustproof box, an absorption pipeline and a chip-proof plate (20), wherein the dustproof box is arranged at a cuttingwork area of the machine tool and provided with an upper open box opening; the absorption pipeline is arranged on the side wall of the dustproof box and used for connecting an absorption device; andthe chip-proof plate is arranged above the dustproof box and used for shielding the upper open box opening, a small gap is reserved between the chip-proof plate and the top edge of the box wall of thedustproof box, and the chip-proof plate is provided with a main shaft hole through which a main shaft of the machine tool passes through freely. The dustproof structure of the machine tool can effectively remove dust produced during machining.

Description

technical field [0001] The invention relates to a machine tool, in particular to a dust-proof structure used to prevent dust from flying during cutting operations. Background technique [0002] It is known that materials such as graphite, wood, composite materials, ceramics and other materials are prone to generate a large amount of dust when cutting or drilling with machine tools. The dust particles are very fine, but the hardness is very high. If the dust-proof facilities are not perfect, the dust will penetrate into the In the structural system of the machine tool, it will cause damage to the machine parts or even a short circuit in the circuit system. [0003] One of the known dust-proof methods is to adopt the water curtain dust-proof method, and water forms a circular screen to surround the cutting work area, so that the cutting dust is covered by the water curtain to reduce the spillage to the outside. The running water is collected, filtered and reused. Disadvantag...

AI Technical Summary

Problems solved by technology

[0004] 1. If the water flow is too strong, there may be concerns about damaging the workpiece

[0005] 2. Dust deposits in the water tank, it is not easy to clean

[0006] 3 Some workpieces that cannot be exposed to water (such as workpieces used in semiconductor equipment) cannot use this dustproof method

[0008] 1. Due to the fact that the dust suction pipe cannot touch the workpiece and cannot affect the automatic tool change of the cutting tool, etc., the dust suction pipe and its air inlet are far away from the machining spindle and the cutting point, resulting in poor dust collection effect good

[0009] 2. When the length of the cutting tool is very long, the air inlet is farther away from the cutting point, and the dust suction effect is even worse

[0010] 3. The cutting work area is an open space, the air flow velocity near the air inlet is fast, and the air flow velocity far away from the air inlet is slow, so that the inhalation amount of dust far from the air inlet decreases sharply, and even cannot be inhaled, while Open spaces allow cutting dust to fly around, making vacuuming less effective

[0013] In the dust-proof box, the air flow velocity close to the air inlet of the dust suction pipe is fast, and the air flow velocity far away from the air inlet is slow, so that the inhalation of dust far from the air inlet decreases sharply, and even cannot be absorbed. Inhalation, poor vacuuming

[0014] When the height of the workpiece is high, the cutting point is above the air inlet and far away from the air inlet, the cutting dust is easy to fly from the box mouth, and the dust collection effect is deteriorated.
