Dust scattering-protection device of an artificial tooth machine

The present invention relates to a mechanism that prevents dust from scattering when processing a workpiece through a tool on an artificial tooth processing machine. More specifically, the inside of the dust collector is formed on an inclined surface to concentrate the dust in the suction hole and induce a perfect discharge. By blocking the scattering of dust generated during processing through the sealing cover and blocking means at the source, it has the advantage of wet type to prevent environmental pollution while providing a pleasant working environment, ease of operation and cost according to maintenance and manufacturing The present invention relates to a dust blocking mechanism of an artificial tooth processing machine that maximizes the overall processing efficiency by having all the advantages of a dry type that reduces the cost.

In general, when a tooth is lost due to tooth decay, gum disease or trauma, the lost tooth is repaired using an artificial material, and the reduced function, appearance, and pronunciation are normally restored through the artificial tooth. The process is called prosthesis. At this time, gold has been mainly used as a material of artificial teeth, but in recent years, it is difficult to use any more due to the sharp increase in the price of gold. In addition, when artificial teeth were made using this metal material and were treated, there were many differences from existing tooth colors, which did not give patients satisfaction.

As such, as the demand for patients' strong aesthetics and raw materials increase, the use of prosthetics using metals gradually decreases, and the use of zirconia, a ceramic material, as a composite material close to tooth color is rapidly increasing. Zirconia is highly brittle and undergoes high-temperature sintering after the artificial teeth are processed in the plasticized state. In addition, zirconia was impossible for humans to process directly with micrometer precision. Furthermore, given that zirconia has different shrinkage rates for each manufacturer of the material at the time of sintering and shrinkage occurs at a constant rate after sintering, it is practically not possible to process by hand using zirconia as an artificial tooth material (workpiece). As it is impossible, we used an artificial tooth processor with CAD / CAM technology.

On the other hand, the artificial tooth processing machine is provided with a chuck which performs forward and backward movement and rotation while clamping the workpiece on the bed frame, and a tool that rotates at high speed while moving left, right, up and down on the upper frame. . That is, while clamping the workpiece to the chuck and then rotating the workpiece 360 degrees along with the movement forward and backward, the tool was processed three-dimensionally through three or more axes of movement through the left, right and up and down movement. At this time, the artificial tooth processor generates dust from the workpiece during processing, which contaminates the working environment, damages the health of workers, provides the cause of environmental pollution, and furthermore, because the particles of the dust are very fine. There is a problem that causes the failure of devices and devices. Therefore, the artificial tooth processing machine must be equipped with a blocking mechanism for blocking the dust according to the process when processing.

The blocking mechanism mounted on the artificial tooth processor is classified into dry and wet depending on whether water (cutting oil) is used. In the wet type, dust generated from the workpiece may not be blown away and thus free from harmful environment, but due to water absorption. There is a problem that the strength of the workpiece is reduced and the possibility that the fracture occurred during the machining process is not revealed. In addition, the wet type requires a tank to receive the water, a pump to circulate the water, and a plurality of filters to recycle the water absorbing the dust, so that the structure for implementing this is considerably complicated and increases the maintenance cost. There is a problem that acts as a factor to increase the volume and price of the artificial tooth processing machine. Therefore, the problem of the wet type has been urgently required to improve the dust blocking mechanism of the dry artificial tooth processing machine.

1 is a perspective view schematically showing a dust blocking mechanism of a conventional artificial tooth processing machine.

The dust blocking mechanism of the conventional dry artificial tooth processing machine 1 is a house which prevents the scattering of dust generated from the workpiece 5 during processing to the outer circumferential surface of the chuck 2 clamping the workpiece 5 as shown in FIG. 1A. The pain relief 3 was provided integrally. In addition, although not shown through the drawings, the suction pump was provided inside or outside the artificial tooth processor 1. At this time, the dust collecting container 3 is formed in a simple box-shaped structure having a space for accommodating the workpiece 5 together with the chuck 2 therein. That is, the lower part of the dust collecting container 3 is provided with a suction port communicating with the suction pump to suck in the collected dust and discharge the dust to the outside (collection box).

However, the dust blocking device having the structure as described above has a problem that the dust is not collected to the inlet side since the inside of the dust collecting container 3 is simply formed in a straight structure, and thus dust is continuously accumulated and cannot be discharged to the outside. In addition, the processing of the workpiece 5 clamped to the chuck 2 by the tool T did not substantially prevent dust scattering. That is, the dust is a fine particle of micro units are easily scattered under the influence of the wind, where as the tool (T) rotates at a high speed, as shown in Figure 1b, the dust outside the dust collecting container (3) There is a problem of scattering in large quantities. Furthermore, there is a closed end in which the amount of dust scattering to the outside increases significantly rather than the amount of dust collected in the dust collecting container 3 because the tool T is not rotated in a stationary state but moves left and right.

Therefore, as dust is scattered to the outside of the dust collecting container 3, it contaminates the working environment, impairs the health of workers and provides a cause of environmental pollution, and breaks down the artificial tooth processing machine 1 as well as other devices and devices. There is a problem that causes. On the other hand, although it may be integrally provided with a cover body that blocks itself on the artificial tooth processing machine (1), there is still a problem that causes the failure of the precise parts existing inside the artificial tooth processing machine (1).

Accordingly, the present invention is to solve the conventional problems as described above, by forming the interior of the dust collector to the inclined surface to concentrate the dust to the suction hole to induce the perfect discharge and occur during processing through the sealing cover and blocking means By blocking the scattering of dust, the wet type prevents environmental pollution while providing a pleasant working environment, and has the advantages of dry type which reduces the cost and ease of operation and cost of maintenance and manufacturing. The purpose of the present invention is to provide a dust blocking mechanism of an artificial tooth processing machine that maximizes the overall processing efficiency.

In order to achieve the above object, the present invention provides a mechanism for preventing dust from scattering when processing a workpiece through a tool on an artificial tooth processor, comprising: an inclined surface for collecting dust while receiving the workpiece, and having a dust at the bottom of the inclined surface Dust collector having a plurality of suction holes for sucking the; An airtight cover having a stepper to be detachably attached to an upper end of the dust collector, and a working cover to move the tool in a received state; And blocking means for preventing the dust generated from the workpiece onto the work of the sealing cover to be scattered to the outside.

At this time, the blocking means according to the invention is characterized in that it comprises a brush for inducing dust to be scattered from the workpiece by preventing the movement of the tool on the working path of the closed cover.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a mechanism for preventing dust from scattering when processing the workpiece (5) through the tool (T) on the artificial tooth processing machine (1), dust collecting box 10, sealing cover 20, blocking means 30 The dust blocking mechanism of the artificial tooth processing machine, which is mainly composed of). Here, the artificial tooth processor 1 is of a dry type, and separately provided with a suction pump for sucking dust and a collecting container for filtering the sucked dust.

The dust collecting box 10 according to the present invention includes an inclined surface 11 for collecting dust while accommodating the workpiece 5, and has a plurality of suction holes 15 for sucking dust at the lower end of the inclined surface 11. Equipped. The dust collecting box 10 is a box shape having a predetermined space therein and is provided integrally or detachably on a bed frame moving forward and backward of the artificial tooth processing machine 1. In addition, the dust collecting box 10 includes a chuck 2 that rotates while clamping the workpiece 5 in a space provided therein. That is, as shown in Figs. 2 and 3, the dust collecting box 10 is moved forward and rearward while accommodating the workpiece 5 inside by the chuck 2.

This dust collecting box 10 has an inclined surface 11 which guides the workpiece 5 clamped therein to collect dust generated by the tool T. The inclined surface 11 is bent at a predetermined angle to induce dust to be concentrated at the lower end. At this time, the lower end of the inclined surface 11 is provided with a plurality of suction holes 15 in close communication with the suction pump. That is, as shown in FIG. 3, the dust collected through the inclined surface 11 is discharged to the outside (collection bin) through the suction hole 15. Therefore, when the workpiece 5 generates dust by the tool T, the dust is collected on the inclined surface 11 to the suction hole 15 provided at the lower end, and at the same time, the dust is sucked into the suction hole 15 to be dusted. It will be discharged completely to this outside.

On the other hand, the discharge process of dust generated from the workpiece (5) has been described step by step for a detailed description, but the inside of the dust collector (10) is a state in which the pressure is continuously low by the suction pump in communication with the suction hole (15) The dust is generated from the workpiece 5 and discharged to the outside through the suction hole 15 at the same time.

In addition, the airtight cover 20 according to the present invention is provided with a stepped portion 21 to be detachably attached to the upper end of the dust collecting box 10, the work path 25 to move the tool (T) in the received state Equipped. The sealing cover 20 is a cover body formed in a shape corresponding to the upper end of the dust collecting box 10, and is attached to the upper end of the dust collecting box 10 to guide the work piece 5 provided in the inner space to be sealed from the outside. That is, the seal cover 20 is interlocked with the blocking means 30 to be described later as shown in Figure 2 to block the dust generated from the workpiece (5) by the tool (T) to the outside.

Such, the sealing cover 20 is provided with a step (21) for precise attachment while inducing detachable guidance on the upper end of the dust collector (10). As shown in Figure 4, the stepped jaw 21 is provided to extend to the lower portion of the sealing cover 20 to be fitted into the top of the dust collecting box (10). Thus, through the step (21) to the top of the dust collecting box 10 to enable a more robust and precise attachment to prevent detachment at random during processing. At this time, the sealing cover 20 is provided with a work path 25 for accommodating the tool T for processing the workpiece 5 to the center. The work path 25 receives the tool T into the dust collecting box 10 and simultaneously guides the tool T to move from side to side. Therefore, the sealing cover 20 is interlocked with the blocking means 30 to induce dust to be generated from the workpiece 5 and scattered to the outside, while the tool T is provided through the step 21 and the work path 25. It provides a smooth environment for processing the workpiece (5).

On the other hand, the sealing cover 20 is shown in a divided state into a mounting frame that is inserted into the interior of the holder frame and the dust collecting box 10 mounted on the top of the dust collector 10, as shown in FIG. It is also possible to form the insertion frame integrally. In addition, the dust collecting box 10 to the stepped portion 21 of the airtight cover 20 and the packing is further provided to have a more improved sealing force is not excluded.

In addition, the blocking means 30 according to the present invention prevents dust generated from the workpiece 5 onto the working path 25 of the airtight cover 20 to be scattered to the outside. The blocking means 30 blocks dust generated from the workpiece 5 by the tool T and scatters to the outside, and the workpiece 5 accommodated inside the dust collector 10 is scattered by the tool T. To induce the path of the dust to be switched, that is, the blocking means 30 is provided on the working path 25 of the airtight cover 20 to collect dust scattered from the workpiece 5 by the tool (T) ( The path is switched to the inclined surface 11 provided in the inside of the 10 to prevent dust from being scattered out of the dust collecting box 10.

At this time, the blocking means 30 according to the present invention collects dust scattered from the workpiece 5 without disturbing the movement of the tool T on the work path 25 of the airtight cover 20 (10). A brush 35 is guided to). The blocking means 30 is to prevent dust from scattering and spilling out of the dust collecting box 10, and has a brush 35 on the work path 25 of the airtight cover 20. Brush 35 is made of a natural or synthetic hair having a predetermined elasticity and strength, and is provided with the working furnace 25 to be completely sealed in a state facing each other on the working furnace 25 in one direction. The brush 35 is disposed horizontally on the work path 25 as a material that prevents dust from being scattered but accommodates the tool T according to the processing and does not affect the lateral movement. Of course, the brush 35 is not limited to the above-described materials and does not exclude that the brush 35 is formed of a metal material or a synthetic metal material. In any case, those skilled in the art will be able to form various materials within a range that does not suggest scattering of dust and movement of the tool (T).

In use using Figures 2 to 5, first, the artificial tooth processing machine (1) is a state in which the dust collector 10 is moved forward, the initial seal cover 20 is detached to the upper end of the dust collector (10) It is a state. After clamping the workpiece 5 with the chuck 2 provided inside the dust collecting box 10 in the initial state, the sealing cover 20 is attached to the upper end of the dust collecting box 10. At this time, as the sealed cover 20 is attached to the upper end of the dust collecting box 10, the inside of the dust collecting box 10 is blocked from the outside.

Subsequently, when the machining is performed, the dust collecting box 10 moves to the rear in which the tool T is located, and the suction pump communicating with the suction hole 15 is operated. At this time, when the suction pump communicating with the suction hole 15 is operated, the interior of the dust collecting box 10 has a vacuum state. Subsequently, the tool T, which is commanded by an image and a numerical value input to the computer, is lowered to a position adjacent to the workpiece 5 for processing. That is, as shown in FIG. 5A, the tool T is accommodated in the dust collecting box 10 through the work path 25 of the airtight cover 20.

Subsequently, the tool T is processed in the form of a tooth while the tool T moves from side to side on the work furnace 25. When the tool T processes the workpiece 5 as shown in FIG. 5B, dust is generated from the workpiece 5 and dust is scattered at the same time. Here, the dust generated indirectly from the workpiece (5) to the tool (T) falls down due to the pressure difference of the suction pump and is discharged to the outside while passing through the inclined surface (11) and the suction hole (15), but to the tool (T). Dust directly affected or affected by rotation has the property of overcoming the pressure difference of the suction pump and flying upward. In addition, since the shape of the tool T is formed in the form of a screw, as the strong vortex is formed around the tool T, dust scattering is further intensified. When dust is scattered to the upper part of the dust collecting box 10 by the tool T as described above, the blocking means 30 switches the dust path downward to guide the dust collecting box 10.

Therefore, even if dust is scattered from the work piece 5 by the tool T, the brush 35 reinduces the dust box 10 to prevent leakage to the outside. On the other hand, when the tool (T) is moved to the left and right on the work path 25, the brush 35 is minutely opened minutely, leading to a state in which the inside of the dust collector 10 is opened to the outside, but the brush 35 The elasticity of the restoring it again in a moment.

As described above, the dust blocking device of the present invention forms the inside of the dust collecting container with an inclined surface to concentrate dust to the suction hole to induce the perfect discharge and to prevent the scattering of dust generated during processing through the sealing cover and the blocking means at the source. Therefore, it has the advantages of the wet type to prevent environmental pollution while providing a comfortable working environment, and maximizes the overall processing efficiency by having the advantage of the dry type to reduce the ease of operation and cost according to maintenance and manufacturing.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
