Description

Technical Field [0001] The present invention relates to a drilling device for processing an eyeglass lens,

The present invention relates to a drilling apparatus for processing a spectacle lens, and more particularly, to a drilling apparatus for processing a spectacle lens which can effectively prevent penetration of washing water and is easy to replace a drill bit.

In order to manufacture a spectacle lens, a commercially available circular lens (usually called a blank lens) should be processed into the shape of a desired spectacle lens. For example, if a circular lens is fixed with a clamp, and an edge of the circular lens is polished by a rotating grinder, and the grinder is appropriately polished around the entire circumference of the circular lens, Can be produced. As described above, in order to attach a nose ring, a spectacle frame, a spectacle frame, etc. to the spectacle lens after the spectacle lens is processed, a hole may be formed in the spectacle lens.

In order to form a hole in the spectacle lens, conventionally, a separate manual drill, a desk drill, or the like has been used, but recently, a drilling device for a hole drilling is further attached to a spectacle lens processing apparatus (for example, , Patent Registration No. 10-1079037, etc.). 1 is a view showing a structure of a drilling apparatus used in a spectacle lens processing apparatus. As shown in Fig. 1, a typical drilling apparatus includes a drill 10 to which a drill bit for drilling is mounted; A drill position control unit (80) for vertically moving the drill unit (10) and changing the direction of the drill bit by rotating the drill unit (10); A vertical drive motor 82 for vertically moving the drill position control unit 80; A drill bit drive motor 88, and the like. In operation, when the up / down driving motor 82 rotates to rotate the up / down driving screw 84, the nut portion 86 screwed to the up / down driving screw 84 moves up and down, The drill position control unit 80 coupled to the drill position control unit 86 also moves up and down to a desired position. A drill tilting motor (not shown) is provided inside the drill position control unit 80 to rotate the drill unit 10 so that the drill bit is directed in a desired direction. When the vertical position of the drill position control unit 80 and the direction of the drill unit 10 are adjusted as described above, the drill bit drive motor 88 is driven, A pulley, a drive shaft, a bevel gear, or the like, and rotates the drill bit of the drill 10 to form a hole in the lens.

In the drilling using such a drilling machine, a large amount of wash water must be supplied to the drill bit in order to clean the lens working debris and to remove the heat generated in the drilling. In order to prevent the washing water from penetrating into the drill 10, two rotary seals are usually installed in the spindle for rotating the drill bit in the forward and backward directions. Since such a rotary seal serves as a load for rotation of the spindle, there is a risk that the driving force of the drill bit drive motor 88 is lost, the rotary seal portion is worn, and the wash water penetrates into the drill portion 10. [ Further, in the case of the conventional drill 10, when the drill bit is worn and replaced, the spindle rotates and the process of unscrewing and tightening the jaw for fixing the drill bit can not be performed smoothly there was.

It is an object of the present invention to provide a drilling apparatus for processing a spectacle lens which reduces the driving force loss of the drill bit drive motor and reduces the risk of leakage due to the wear of the rotary seal by using only one rotary seal. It is another object of the present invention to provide a drilling apparatus for processing a spectacle lens which can be easily and simply replaced with a drill bit.

In order to achieve the above object, the present invention provides a drill bit for forming a hole in a lens; A spindle in which the drill bit is fitted and fixed, the spindle rotating the drill bit; A tightening portion for fixing a drill bit fitted in the spindle; A housing rotatably receiving the spindle; A rotatable closure formed around the spindle to prevent water from passing between the spindle and the housing; And a spindle fixing part for detachably fixing the spindle to the spindle, the spindle fixing part being detachably mounted on one end of the spindle, The present invention provides a drill apparatus for processing a spectacle lens.

According to the drilling apparatus for processing a spectacle lens according to the present invention, by using only one rotary seal, the driving force loss of the drill bit drive motor is reduced, the risk of leakage due to wear of the rotary seal is small, Replacement can be performed simply and conveniently.

FIG. 5 is a view showing a state (A) and a state (B) in which the spindle is not fixed by the spindle fixing portion in the drilling apparatus for spectacle lens processing according to the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In the accompanying drawings, elements having the same or similar functions are denoted by the same reference numerals. 2 and 3 are a rear perspective view and a longitudinal cross-sectional view of a drill for a spectacle lens processing according to an embodiment of the present invention, respectively. 2 and 3, a drill apparatus for processing a spectacle lens according to an embodiment of the present invention includes a drill bit 12, a spindle 20, a jaw 22, 26, a seal, a housing 70, and a spindle fixing portion 30.

The drill bit 12 is a conventional drill device for forming a hole in a lens, and comprises a drill blade for grinding the lens to form a hole and a drill body for supporting and fixing the drill bit. The spindle 20 rotates about the axis of the spindle 20 and rotates the drill bit 12 as the drill bit 12, specifically a drill body of the drill bit 12, . A jaw portion 22 jaw for fixing a drill bit 12 fitted to the spindle 20 is mounted at one end of the spindle 20, specifically, at a distal end to which the drill bit 12 is fitted, (20) and the drill bit (12) do not slip but rotate integrally. The throttle portion 22 is a conventional device for coupling the spindle 20 and the drill bit 12 and rotates the throttle portion 22 about the spindle 20. For example, a screw is formed in the tapered shape at the inside of the throttle portion 22 and at the end of the spindle 20 so that when the throttle portion 22 is turned and coupled to the spindle 20, 20 and the drill bit 12 are coupled with each other and the thrust section 22 is reversely turned and released from the spindle 20 so that the spindle 20 and the drill bit 12 are separated from each other, The drill bit 12 can be taken out from the drill bit 20.

A gear portion 24 for rotating the spindle 20 may be formed at one end of the spindle 20. The gear portion 24 is engaged with a drive gear 90 that transmits the driving force of the drill bit drive motor 88 Lt; / RTI > bevel gear. A rotary seal 26 is formed at one end of the spindle 20 along the circumference of the spindle 20 to prevent water from passing between the spindle 20 and the housing 70. For example, the rotary hermetic sealing portion 26 is formed along the periphery of the spindle 20 and rotates together with the spindle 20, and at one end of the rotary hermetic sealing portion 26, And the wing portion 26a supports the side surface of the housing 70. As shown in Fig. Therefore, even if the spindle 20 rotates at a high speed in the housing 70, the wing portion 26a has elasticity, so that the space between the spindle 20 and the housing 70 can be sealed.

The housing 70 serves as a body for rotatably receiving the spindle 20. For example, the spindle 20 is rotatably supported by one or more bearings 72 mounted inside the housing 70. One end of the spindle fixing part 30 is located inside the housing 70 and the other end of the spindle fixing part 30 is fixed to one end of the housing 70. [ And the other end is located outside the housing (70). The spindle fixing part 30 is detachably coupled to one end of the spindle 20 and functions to limit the rotation of the spindle 20. 4 is a perspective view of a spindle 20 and a spindle fixing portion 30 that can be used in the present invention. 3 and 4, a locking protrusion 28 is formed at one end of the spindle 20 and a locking groove 32 is formed at one end of the spindle fixing portion 30, When the engaging projection 28 of the spindle 20 is fitted into the engaging groove 32 of the spindle fixing portion 30 by the movement of the spindle fixing portion 30 toward the spindle 20, , Rotation of the spindle 20 is restricted. That is, the spindle fixing unit 30 and the spindle 20 are engaged and rotated or stopped together. Of course, it is also possible to form a latching groove at one end of the spindle 20, and to form a latching protrusion at one end of the spindle fixing part 30. 3, a sealing member 38 for sealing the space between the housing 70 and the spindle fixing unit 30 may be disposed between the housing 70 and the spindle fixing unit 30. [ have. The sealing member 38 may be in the form of an O-ring and may be fixed to a groove formed in the housing 70, . It is preferable that an elastic member 36 is mounted between the spindle fixing part 30 and the housing 70 so as to bring the spindle fixing part 30 into close contact with the spindle 20 in the opposite direction. Since the elastic member 36 moves the spindle fixing portion 30 in the opposite direction to the spindle 20, if the spindle fixing portion 30 and the spindle 20 are not engaged, And the spindle fixing unit 30 and the spindle 20 are engaged only when the spindle fixing unit 30 is moved in the direction of the spindle 20 by an external force. The elastic member 36 may be a conventional spring for urging the spindle fixing portion 30 outwardly of the housing 70, and preferably a compression spring may be used. A hook 34 may be formed at one end of the spindle fixing part 30 to prevent the spindle fixing part 30 from separating from the housing 70.

Next, the operation of the drilling apparatus for eyeglass lens processing according to the present invention will be described with reference to Figs. 1 to 5. Fig. 5 is a view showing a state (A) and a state (B) in which the spindle 20 is not fixed by the spindle fixing unit 30 in the drilling apparatus for spectacle lens processing according to the present invention. 5 (A), when the drill for eyeglass lens processing according to the present invention is in normal use, the elastic member 36 closely contacts the spindle fixing portion 30 in the outer direction of the housing 70, The fixing portion 30 and the spindle 20 are separated from each other. 3) is rotated by the driving force of the drill bit drive motor 88 to rotate the drill bit drive motor 88 (see Fig. 1) The gear portion 24 connected to the bevel gear engagement also rotates. Therefore, the spindle 20 coupled to the gear portion 24 and the drill bit 12 coupled to the spindle 20 can be rotated to form a hole in the lens. At this time, watertightness is maintained between the housing 70 and the spindle 20 by the rotation sealing part 26, and between the housing 70 and the spindle fixing part 30, the sealing member 38, The watertightness is maintained.

5 (B), when the drill bit 12 is replaced by the wear of the drill bit 12, the spindle fixing portion 30 is moved from the outside of the housing 70 to the spindle fixing portion 30, (20), thereby coupling the spindle fixing portion (30) and the spindle (20). When the spindle fixing unit 30 and the spindle 20 are coupled with each other, the spindle fixing unit 30, which is exposed to the outside of the housing 70, is fixed by fitting a mechanism such as a hand or a pin, ). When the spindle 20 is fixed, the throttle portion 22 can be turned to separate the spindle 20 from the drill bit 12 and take out the worn drill bit 12 from the spindle 20. If the spindle 20 is not fixed as described above, the throttle portion 22 and the spindle 20 rotate together, and it is difficult to turn the throttle portion 22 away from the spindle 20. Next, instead of the worn drill bit 12, the new drill bit 12 is wedged into the spindle 20 and the throttle 22 is turned in the opposite direction to firmly couple the spindle 20 and the drill bit 12 The elastic member 36 pushes the spindle fixing portion 30 in the direction opposite to the spindle 20 so that the spindle fixing portion 30 is rotated from the spindle 20 .

According to the drilling apparatus for the spectacle lens processing according to the present invention, the water tightness in the inside and the outside of the housing 70 is maintained by the one rotary seal member 26 and the one fixed seal member 38, 88 can be lowered and the abrasion of the rotary sealing member 26 and the sealing member 38 can be suppressed and the problem of water infiltration due to abrasion of the sealing member can be reduced. In addition, when the drill bit 12 is replaced, the rotation of the spindle 20 for mounting the drill bit 12 is prevented, and the process of unscrewing and tightening the tightening portion 22 for fixing the drill bit 12 is smoothly performed .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
