Description

{A CHAMFERING MACHINE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bevel gear, and more particularly, to a bevel gear capable of improving the quality of a machined product by chamfering the edge of a beveling object by a grinding method,

In general, the chamfering machine is a device for chamfering the edge of a face-to-face object processed by a machine tool such as a hexahedron.

The conventional chamfer has a motor for rotating a rotary block provided with a cutter, and a support provided on the upper side of the cutter and having a V-shaped cross section. At the lower end of the support, a penetrating portion is elongated along the longitudinal direction, and the edge of the object to be faced is exposed downward through the penetrating portion.

When the worker places the object to be supported on the support and pushes the object to be moved after the motor is operated, the lower exposed edge is cut through the penetration part.

The cutting edge portion of most of the cutters employed in these conventional chamfering machines is made of an ultra-hard alloy. The carbide tool is extremely high in hardness close to diamond and has excellent oxidation resistance at high temperature. Therefore, it is possible to perform a heavy cutting operation at a higher speed than a high speed tool steel. The cemented carbide as a cutting tool is classified into three kinds of P, M, and K depending on the type of workpiece. For example, P is used for steel, M for stainless steel, and K for cast iron. The larger the number after the symbol is, the better the toughness. The smaller the number, the greater the abrasion resistance and heat resistance.

However, the conventional chamfering machine uses a cutter having a superfine cutting edge as described above. Such a superfine cutting edge can be formed by machining a high hardness metal material and a tough material such as a stainless steel (SUS) The durability is remarkably lowered. Accordingly, since the cutter needs to be frequently replaced, the manufacturing cost is increased and the product cost is increased.

Further, when a chamfering machine using a conventional cutting method is used, chamfering of large chip particles may cause fatal injuries to the operator, and the machining work space becomes dirty, requiring additional cleaning work .

In addition, if chamfering is performed using a conventional chamfering machine, burrs are formed on the chamfered surface of the object to be chamfered, thereby deteriorating the quality of the product.

In addition, the conventional chamfer has a complicated configuration of the apparatus, which limits the installation space, and there is a problem that noise and vibration are severely generated during the machining operation.

The guide block 24 is coupled to the guide rod 23 so that the inner circumferential surface of the bearing 24b mounted on the through hole 24a encloses the outer circumferential surface of the guide rod 23. [ Accordingly, the guide block 24 is rotatable about the guide rod 23 and is reciprocatingly linearly movable along the first direction. As described above, there is, for example, a rotary ring bearing PRT of a bearing 24b employed for adjusting the rotation angle when the guide block 24 rotates.

On the other hand, the first flat plate 25 and the second flat plate 28 may be provided with clamps to secure the chamfering object so that chamfering can be stably performed. As described above, since the first flat plate 25 and the second flat plate 28 are detachably provided, only the rotating body 32 can be easily removed from the apparatus when the rotating body 32 needs to be replaced in the chamfered portion 30 .

The height adjusting portion 29 is provided to support the sliding member 27 and adjust the height of the sliding member 27. The height adjusting portion 29 is provided with guide grooves 27b and 27d The guide protrusion 29a has a shape corresponding to the shape of each of the guide grooves 27b and 27d at positions corresponding to the guide grooves 27b and 27d. 5, the height adjusting portion 29 includes a support shaft 29b provided in the horizontal direction toward the first guide portion 21 and a support shaft 29b coupled to the support shaft 29b, And a bearing 29c for supporting a lower portion of the bearing 29c. 5, the height adjuster 29 is integrally coupled to the support shaft 29b and the bearing 29c and is movable up and down.

6 is a view showing a configuration of a chamfered portion in a chamfering machine according to a preferred embodiment of the present invention.

The chamfered portion 30 includes a rotating body 32 including a grinding portion 32a and a tightening body 34 as shown in Fig.

The rotating body 32 is formed in a container shape having an upper portion in an annular shape and a through hole is formed in a bottom surface of the body 32. The rotating body 32 is detachably attached to the body 10 and the driving motor 14. [ Lt; / RTI > Further, the rotating body 32 is formed on the upper surface and / or the side surface and includes a grinding portion 32a that grinds the edge of the object to be faced in a grinding manner. By adopting the grinding-type chamfered portion 30 in this manner, it is possible to prevent the generation of chips with large particles during chamfering work, thereby preventing the worker from being injured and keeping the working environment clean. Further, occurrence of burrs on the chamfered surface of the object to be cotton can be remarkably reduced, and a constant quality can be maintained regardless of the technical level of the person to be processed.

The tightening body 34 is detachably coupled to a rotation axis projection 16a protruding from the bottom surface of the rotating body 32 so as to tighten the rotating body 32 so as not to be detached from the rotation axis 16, The fastening hole 34a is formed with a screw thread having a shape corresponding to the screw thread formed in the screw hole 34a. At this time, the cross-sectional shape of the rotary shaft projecting portion 16a and the tightening hole 34a has a square or hexagonal shape so that the rotational force transmitted from the drive motor 14 can be received more reliably. If the cross-sectional shape of the rotary shaft projecting portion 16a and the tightening hole 34a is circular, power transmission can be smoothly performed using a key, a pin, or the like.

On the other hand, the grinding portion 32a and the rotating body 32 adopt one of a CBN (Cubic Boron Nitride) wheel, a diamond wheel, a vitrified grindstone wheel, and a grindstone wheel depending on the material of the object to be fastened can do. These wheels are suitable for machining high tenacity metal materials and toughness materials such as stainless steel (SUS) based metals. In addition, since a grinding portion made of a material having high durability is employed, it is not necessary to frequently replace the grinding portion, so that the machining cost can be reduced and the product cost can be lowered.

The CBN wheel is an inorganic ball type, but the bond is adequately worn, so the pocket necessary for discharging the chip is sufficiently formed. Therefore, the grinding process can be performed for a long time without dressing the wheel, so that the number of times of the wheel modification can be shortened and the time can be saved. In addition, the CBN wheel is chemically bonded to the powder material and the bond at a high strength, so that the loss of the CBN powder is small and the production cost can be reduced. In addition, since the abrasion is reduced, the processing numerical adjustment is greatly reduced, and the bit ribbon is stronger than the resin bond, so that ultra-precision processing is possible. CBN (cubic boron nitride) used in these wheels is a synthetic material that does not exist in nature. It is harder than diamond and harder than twice as hard as alumina grinding particles or silicon carbide grinding particles of general grinding machine. Since diamond has a property of abrading and abrading by chemical reaction during grinding with elements such as iron, cobalt, and nickel, it is not suitable for grinding of iron-based metal materials, but since CBN is difficult to chemically react with these elements, It has superior heat resistance to diamond and excellent in grinding of metal and alloy series. Its oxidation rate is slow in air and stable up to 1200 ℃.

A diamond wheel is a grinding tool in which fine powder of industrial diamond is sintered together with an artificial resin or the like. Metal diamond wheel is sintered with metal powder and has excellent abrasion resistance and shape retaining ability and is used for glass and stone. Resin Diamond wheels are made of phenol or polyamide resin, and have two types, wet and dry. It has excellent elasticity and low grinding resistance. It is used for grinding of cemented carbide and ceramics.

The tritide used in the vitrified grinding wheel is generally referred to as the tritide binder and is represented by the symbol "V". Minerals such as feldspar and clay are baked at a high temperature of about 1,300 ° C and hardened to bond the abrasive grains. The range of coupling degree is wide and the adjustment of the tissue can be simplified. It is suitable for grinding of tools and inner grinding which avoid heat because of good cutting ability. It is characterized by a clear sound when you tap on anything. When checking, listen to the sound and judge whether it is cracked or not. This grinding stone has a lot of pores and does not change to water, alkali, acid, oil, etc. Therefore, it is widely used for general grinding work including precision grinding. However, since it is very easy to be a defect, Things absolutely must be avoided. It is difficult to produce a thin grinding wheel, and its service life and machinability are halfway between metal and resinoid. It should always be used for wet grinding, and it is used for rough, medium finishing, hand polishing work of cemented carbide.

Abrasive grinding wheel used in abrasive wheel is classified according to the type of binder to which abrasive is bonded, and its preparation and characteristics are various.

Accordingly, the two driving portions, that is, the chamfered portion 30 and the decoupling portion 40 can be driven by using one driving motor 14. [ As in the present invention, it is possible to use a friction train as a power transmission mechanism or adopt a belt or a chain other power transmission mechanism. However, it is advantageous to use a friction train system in order to secure a space for installation and minimize noise vibrations. At this time, the first friction disk 18 fitted in the middle of the rotating shaft 16 for rotating the rotating body 32 of the chamfered portion 30 is engaged with the second friction disk (second friction disk) 43, the first friction disc 18 is rotated at a higher speed than the second friction disc 43, and the second friction disc 43 is rotated at a higher speed although the number of revolutions is smaller. Further, the first friction disk 18 and the second friction disk 43 are rotated in mutually opposite directions.

Such a ceramic fiber is a kind of inorganic fiber, and is a fiber made of a ceramic material having excellent heat resistance, corrosion resistance, and abrasion resistance. Alumina silica-based materials are melted to make fibers, and boric acid glass, zirconia, chromium oxide and the like are added if necessary. The raw material is melted at a high temperature of 2,000 ℃ or more to be made into fiber and used as refractory fiber. By adopting the brush 46 made of the flexible ceramic fiber excellent in the corrosion resistance and the frictional resistance in the deburring 40, it is possible to use the brush 46 for a long period of time, have. In addition, since the brush 46 of the detergent dispenser 40 is detachably provided, only the brush 46 can be removed from the detergent dispenser 40 when the brush 46 is worn and needs to be replaced Maintenance and management costs can be saved.
