The present invention relates to a dust collector for a machine for discharging the cutting chip generated during processing to the outside.

Conventionally, a device for collecting a cutting chip around a main shaft of a machine has been implemented, and a mechanism for discharging the cutting chip to the outside of the machine via a hose or the like has been implemented.

Conventional mechanisms have cutting chips attached to the device (especially in resin processing, etc., due to the influence of static electricity and difficult to remove them), and the cutting chips are placed on the tool holder side when the tool is changed in an automatic tool changer (ATC). This may adhere. When the cutting chip is attached to the tool holder, when the tool is mounted on the main shaft again, it may cause the shaking of the tool, leading to deterioration of machining accuracy and deterioration of the machining surface.

In addition, if the cutting chip is caught in the spindle taper and the tool holder, the position of the tool edge is also distorted, resulting in deterioration of the precision of the machining depth.

Conventional processing equipment is installed to interlock with the vertical movement of the main shaft, because of the mechanism for moving the device along with the movement of the main shaft, the gap between the workpiece surface and the brush tip due to the depth of processing caused the scattering of the cutting chips. In addition, when the device is installed in a position where the cutting chip can be prevented from scattering and the processing depth is deepened, the processing is continued while the device tip (brush or the like) is in contact with the work, thereby damaging the surface of the work surface. There is a problem of this deterioration.

There is also a need for a mechanism that prevents the cutting chips from adhering to the tool holders that are waiting in ATC magazines, even during machining with a separate tool. And when cleaning the table of a machine and the periphery of a workpiece | work with an air gun (blower) etc., it is necessary to prevent a cutting chip from scattering and sticking.

The present invention is to solve the above problems, and provides a mechanism to prevent the cutting chip is attached to the tool holder in all kinds of operations, including during machining and automatic tool change.

It is also an object of the present invention to provide an apparatus for maintaining a state in which a cutting chip does not scatter by a mechanism that constantly maintains and fixes the position of the apparatus from the work surface regardless of the machining depth of the tool. .

In addition, the present invention provides a dust collecting device that can cope with all kinds of processing such as material to be processed, tool type, processing conditions by having a function to cool the cutting edge of the tool, such as air, mist, etc. For other purposes.

In order to achieve the above object, the present invention processing dust collecting device is configured to completely prevent the cutting chip from being attached to the tool by completely evacuating the entire dust collecting device to which the cutting chip can be attached during automatic tool change from the spindle and the tool changer. do.

The dust collector according to the present invention is controlled to automatically evacuate by a tool change command without the need for a dedicated command, and to be returned to the machining position automatically after the tool change.

The dust collector according to the present invention implements a mechanism for collecting a cutting chip generated during machining by replacing the tool in a state where the cutting chip is not attached to the tool, and mounting a dust collector near the tool just before processing.

The dust collector according to the present invention is provided with a mechanism for stopping and fixing at a predetermined position immediately before the workpiece surface by a mechanism for accessing the workpiece in conjunction with the spindle head.

In addition, the dust collector according to the present invention is a tool cutting edge (blade end) from the inside of a mechanism and a device capable of performing processing by moving only the spindle head (tool) to a designated machining position after the dust collector is stopped and fixed at a preset position. Is provided with a mechanism for injecting air (such as mist) toward the

Hereinafter, with reference to the accompanying drawings will be described the operation and function of the dust collector according to the present invention.

The dust collector according to the present invention has a mechanism for moving up and down in association with the spindle head around the spindle 1 of the machine, and for fixing the device at a predetermined position, collecting the cutting chips and discharging them out of the machine ( See FIG. 1).

At the time of processing, the dust collector 3 is lowered near the work surface in association with the main shaft 1 and the dust collector positioning mechanism 6. The dust collector 3 is stationarily fixed at a predetermined position due to the action of the dust collector 3 and the dust collector positioning mechanism 6 near the workpiece surface. During processing, the dust collector 3 is fixed in the position of FIG.

The brush 5 attached to the lower part of the dust collector 3 prevents the work 8 from being damaged when the dust collector 3 is set, and does not contact the workpiece at a stationary fixed position.

Thereafter, the spindle head is lowered together with the tool 2 to the position to be machined again and is positioned at the preprogrammed machining position. Only the main shaft 1 and the tool 2 are lowered by the machining groove than the position of FIG. 3 (see FIG. 3).

The work 8 fixed on the machine table is machined by the rotation of the tool 2 fixed to the spindle 1. The cutting chips generated at the time of processing are sucked into the dust collector 3, and are collectively processed by a dust collector outside the machine via the dust collector hose 4. In the processing, the cutting chips are all discharged to the outside of the machine, but the fine cutting chips may remain inside the dust collecting apparatus 3 or inside the dust collecting hose 4.

When the machining of this tool 2 is finished, the tool is changed to the next tool. In the case of tool change, the tool returns to the normal state of FIG. 1 by the reverse process of operation when the machining position is approached. In order to change the tool, the dust collecting device 3 to which the brush 5 and the dust collecting hose 4 are connected is moved from the position of the main shaft 1 in the normal state to the evacuation position. Evacuation of the dust collecting device 3, including the dust collecting hose 4 and the brush 5, moves to the rear of the machine (right direction in FIG. 2) from the position shown in FIG. (See Figure 2). The evacuation operation of the dust collector will be described later.

After the dust collector 3 is evacuated, the automatic tool changer ATC is replaced with the next tool. When the replacement is performed in the automatic tool changer (ATC), since the dust collecting device 3 in which residual cutting chips may be present is evacuated, the tool change is possible without the cutting chip being attached to the holder portion of the exchange tool. Even if the operator changes the tool manually, it can be changed without attaching the cutting chip. After changing the tool, it automatically returns to the normal position and proceeds to the next machining.

The dust collector 3 is provided with an air blower (mist) mechanism that faces the edge of the tool 2. The air blower (mist) 7 cools the processing heat and greatly improves the tool life and the surface quality of the working surface.

4 (a) and 4 (b), the dust collecting apparatus is supported in the state in which the guide 10 is operable back and forth, and is fixed to the cross rail 11 of the apparatus main body. The cross rail 11 is a structure in which the main shaft unit and the dust collector of the machine body are fixed.

In a normal state such as during machining, the dust collector is positioned and fixed at a position during machining. The cutting chips generated by the machining at this position are completely discharged to the outside of the machine via the dust collecting hose 4. Cutting chips generated during machining between the grooved positions and the grooved positions shown in FIG. 3 are discharged to the outside of the machine through the dust collecting hose 4 (see FIG. 1).

At the time of tool change, the spindle 1 and the tool 2 return to the shanghai-dong exchange position of the spindle head (the position where there is no interference with the dust collector), and the dust collector is retracted to the evacuation position by the evacuation cylinder 9. .

The dust collector 3 is fastened to the guide 10, and is configured to reciprocate the position during the processing and evacuation position of FIG. The reciprocating dust collector 3 has a mechanism connected to the evacuation cylinder 9 and driven by an external signal, and moves to the evacuation position at the time of tool change.

By changing the tool while the dust collector is moved to the evacuation position (two dashed-dotted line position of 4 (b) as the retracted position), it is possible to prevent the cutting chip from adhering to the tool. In addition, the operation of the dust collector to the evacuation position and the position at the time of processing is automatically performed by the control of the machine.

BRIEF DESCRIPTION OF THE DRAWINGS The drawings attached to this specification are merely intended to clearly show some of the technical ideas included in the present invention, and modifications that may be easily inferred by those skilled in the art within the scope of the technical ideas included in the specification and drawings of the present invention. It is obvious that both and specific embodiments are included in the scope of the technical idea of the present invention.

According to the present invention, by evacuating the dust collector during automatic tool change, the cutting chips are not attached to the tool holder at all and the dynamic shaking of the tool is not deteriorated. In addition, since the cutting chip is not attached, the repeatability of tool mounting is increased and the precision of the processing depth is improved.

In addition, according to the present invention, since the brush portion of the dust collector is fixed and fixed regardless of the processing depth near the work surface, it is possible to process without scattering the cutting chip. Since the dust is collected completely during processing, it is possible to perform a good surface quality without damaging the surface of the workpiece.

In addition, by cooling the machined portion with an air blower or the like, the surface quality of the machined surface is improved, the life of the tool is extended, and the running cost is reduced. In addition, since the scattering of the cutting chips is drastically reduced, the cleaning operation of the cutting chips is greatly reduced, thereby improving production efficiency, and at the same time, a clean working environment is realized.
