Description

Work {A work}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a work, and more particularly, to a work for easily and conveniently fixing a hammer or the like used for processing an artificial tooth.

It is easy for modern people to neglect dental care in changing diet and busy everyday life.

On the other hand, as society has recently entered the aging society, there is a growing interest in tooth related technology.

In particular, artificial teeth, including bridges and implants, are now very effective in solving such tooth problems and their demand is increasing day by day.

Therefore, in the conventional artificial teeth, there has been a demand for accurate and fast accurate work in accordance with the needs of various patients, which has been a cause of an increase in the defective rate of the manufactured artificial teeth.

If the patient's desired prosthetic tooth is made in bad condition, the patient will not be able to receive the treatment for the time required for the rework, and the inconvenience of having to visit the dental clinic twice or three times for treatment is inconvenient.

The processing of artificial teeth requires close cooperation between the hospital and the dental clinic.

In other words, at the stroke operator side, a plurality of dental operators produce an artificial tooth based on the patient's tooth information transmitted from the hospital according to their roles.

Such artificial tooth machining on the side of the conventional striking machine often includes manual work of the dental operators.

Therefore, in the case of the dental clinic where the patient's tooth information is transmitted from the hospital side, an erroneous process is produced in the process of manufacturing the artificial tooth, which results in an incorrect result which is different from the intended tooth of the patient.

In order to solve such a problem, artificial tooth machines capable of 5-axis machining have emerged in consideration of conventional machining devices, for example, a milling machine capable of multi-axis machining.

As a representative example, Korean Patent No. 982,778 discloses a 5-axis artificial tooth processing apparatus.

Korean Patent No. 982,778 discloses techniques capable of various clamping according to the shape of a workpiece.

However, the flapping device of Korean Patent No. 982,778 has a complicated structure in fixing the workpiece.

This causes a problem that it takes a long time to fix the workpiece and wasting time and effort in correcting the fixation after fixing once.

This has a problem in that it is not much different from a conventional artificial tooth method in that the artificial tooth is manually machined.

As a result, in the case of Korean Patent No. 982,778, which is a prior art, there is a problem that a quick operation can not be performed.

On the other hand, the types of artificial teeth to be processed in the processing of artificial teeth will be as diverse as the characteristics of patients.

Therefore, a variety of materials must be prepared for processing various artificial teeth.

Particularly, in the case where the workpiece has a rectangular bar shape such as a hammer bar in addition to the disk-shaped zirconia, a work that easily and easily fixes various types of hammer bars is required, but the conventional technology does not deserve it.

Korean Patent No. 982,778

Accordingly, it is an object of the present invention to provide a work for easily and conveniently fixing various types of hammocks.

According to an aspect of the present invention, there is provided a method of manufacturing a semiconductor device, comprising: a holder having at least one screw hole formed therein; And fixing means for applying an urging force in the direction of the holder to the workpiece inserted into the screw hole and disposed between the holder and the fixing member, the fixing member including at least one of a fixing hole and a through hole formed therein; And a workpiece.

The fixing piece is coupled to the holder at a position where the center of the through hole and the center of the screw hole are aligned with each other.

In addition, a plurality of the fixing pieces are provided, and one of the fixing pieces is provided with a concavo-convex portion on a surface which is in close contact with the holder.

Further, the center of the screw hole and the center of the auxiliary groove are orthogonal to each other, and the center of the through hole and the center of the fixing groove are orthogonal to each other.

Further, the fixing piece includes a workpiece having an inclined surface formed at an end thereof.

Further, the holder may include a first side portion having a fastening hole formed therein; A second side portion having a fastening hole at a position opposite to the first side portion;

And a fourth side portion connecting a third side portion connecting one end of the first side portion and one end of the second side portion to each other and connecting the other end of the first side portion and the other end of the second side portion to each other, And a center support portion connecting the first side portion and the second side portion between the first side surface portion and the fourth side surface portion.

And a support rod which is inserted and fixed between the holder and the concave portion formed on one side of the concave-convex portion, the other side of which is inserted into the end portion of the workpiece.

Further, the support rod has a tapered inner peripheral surface to be in tight contact with the tapered end portion of the workpiece.

The present invention as described above has the following effects.

First, there is a strong point that various kinds of work pieces can be easily fixed to a holder by using a holder and a fixing piece fixed to the holder so that the work piece (hammock or the like) is brought into close contact with the holder.

Second, since any one of the fixing pieces is provided with the concave / convex portion, the tip portion of the joining bar can be more easily and smoothly fixed.

Third, since the center of the screw hole and the center of the auxiliary groove are orthogonal to each other, and the center of the through hole and the center of the fixing groove are orthogonal to each other, there is an effect that more reliable fixing can be achieved through fixing in the vertical direction.

Fourth, since the inclined surface is formed at the end portion of the fixing piece, the fixing operation can be performed more quickly and accurately.

Fifth, since the holder includes the center support portion, there is an advantage that various joists or the like can be fixed at one time over two rows between the center support portion and the holder.

Sixth, since the support rods are provided, there is a strong point that it is possible to more securely and easily fix the tip portion of the hammer bar or the like.

Seventh, since the inner circumferential surface tapered is formed on the support bar, there is an advantage that the tip portion of the ham bar or the like can be more smoothly guided and inserted and fixed.

Eighth, there is an advantage that it can work by clamping the abutment round bar material which is provided variously for each of the implant companies.
