Figure 3 is a perspective view of a milling dresser processing dresser according to the present invention, Figure 4 is an exploded perspective view of a milling dresser processing dresser according to the present invention, Figure 5 is a longitudinal cross-sectional view of the milling dresser processing dresser according to the present invention, Figure 6 It is a perspective view of the state in which the goniometer was attached to the dressing machine for milling burrs of this invention.

The present invention as shown in the figure is largely the body 110, the shaft 120, the first / second dresser 130, 130 ', the shaft fixing lever 140, the angle adjustment lever 150 and elastic The member 160 is comprised.

The body 110 may be manufactured in a cylindrical shape having a hollow portion 111 penetrating in the vertical direction in the inner center, and maintains an appropriate weight so as to minimize shaking or sliding during milling machine processing, which will be described later. Make it as possible.

In this case, in order to more effectively prevent the sliding of the body 110, the anti-slip pad may be attached to the bottom bottom.

The shaft 120 is installed in the state capable of axial rotation across the hollow portion 111 inside the body 110 as described above.

At this time, the shaft 120 is provided with a dresser mounting groove 121 for allowing the first and second dressers 130 and 130 'to be mounted at the same angle to be spaced apart from each other by a predetermined distance. In addition, the dresser mounting groove 121 forms a screw hole to which the fastening members 135 and 135 'are fastened.

In addition, the shaft 120 may be coupled to the outer diameter, as shown in Figure 6, an angle meter 125 for measuring the inclination angle of the first / second dresser 130, 130 ', in this case the goniometer 125 Indication needle 113 for measuring the scale of the) can be formed on the top of the body. Of course, the shape or position of the pointer needle 113 and the goniometer 125 is not limited to the one illustrated in the drawings, but may be configured in various forms.

In addition, it is possible to form a rotation control means for the rotation of the shaft 120 is divided rotation by a predetermined angle, preferably 1 ° intervals. This rotation control means is a publicly known technique already widely used, and a separate description thereof will be omitted.

At this time, the outer diameter of one end of the shaft 120 is formed so that the screw tab is formed to penetrate the body 110, and the shaft fixing lever 140 is screwed from the outside of the penetrating body 110 to prevent separation. You can do that.

A pair of first and second dressers 130 and 130 'are coupled side by side at the same angle on the shaft 120, and each of them is screwed in a detachable state.

The first and second dressers 130 and 130 ′ are formed with polished portions 131 and 131 ′ whose top surfaces are electrodeposited with diamond particles, and are disposed below the polished portions 131 and 131 ′. Fixing parts 133 and 133 'are formed on the shaft 120 by using the fastening members 135 and 135', and the inclination adjustment angle in the state coupled to the shaft 120 is in a range of 0 to 8 °. It is desirable to be limited to.

In this case, the first dresser 130 and the second dresser 130 ′ are for polishing the stone point 173 or the rubber point 175 as shown in FIGS. 8 to 9 at a predetermined angle, and are to be polished. Depending on the roughness can be varied.

The stone point 173 is used in the initial processing step, while the rubber point 175 is generally used in the finishing step for surface gloss.

Therefore, the polishing unit 131 of the first dresser 130 for polishing the stone point 173 is preferably electrodeposited to form a diamond particles of 40 ~ 1,000 mesh, the second for polishing the rubber point 175 The polishing unit 131 ′ of the dresser 130 ′ is preferably electrodeposited with diamond particles 120 to 3,000 mesh.

At this time, by operating the angle control lever 150 coupled to the front of the body 110 to rotate the first / second dresser (130, 130 ') to make the angle adjustment, the angle adjustment lever ( 150 is screwed to penetrate the hollow portion 111 in front of the body 110, the front end is advanced and reversed in a grounded state with the lower end of any one of the first / second dresser 130, 130 ' The lower front surface of the first and second dressers 130 and 130 'is rotated about the shaft 120.

The elastic member 160 for installing the elastic restoring force corresponding to the pressing force of the angle control lever 150 is installed to support the lower end of the rear surface of the first and second dressers 130 and 130 '. The elastic member 160, such as a compression spring may be used.

At this time, the elastic member 160 is the elastic member guide screw 137 (137 ') and the hollow portion 111 of the body 110 is fastened to the bottom rear of the first / second dresser (130) (130'). Maintaining a state installed between the pair of elastic member guide bar 161 is protruded inwardly.

7 is a schematic view showing a cutting angle setting operation of the milling dressing machine dresser of the present invention, the milling dresser processing dresser 100 of the present invention may set the cutting angle using a separate goniometer 125, etc., FIG. As shown in FIG. 7, the cutting angle may be set using the metal bur 171 mounted to the milling machine 170. Referring to the setting method using the metal bur 171, first, the surface of the metal bur 171 mounted on the milling machine 170 and the first and second dresser 130 of the dresser 100 for milling burr processing ( 130 ') by using the angle adjusting lever 150 to closely contact the surface and to match the surface inclination, the inclination angle of the metal burr 171 is the first / second dresser 130 of the dresser 100 for milling processing To be set at 130 '.

8 to 9 are schematic views showing a process of machining the cutting angle of the stone point / rubber point using the dressing machine for milling burrs of the present invention, as shown in the same figure as a stone point (mounted to the milling machine 170) 173 and rubber point 175 are supplied in a cylindrical shape without a cutting angle. At this time, the dresser 100 for milling processing is already set to a predetermined cutting angle. In this state, the first and second dressers 130 and 130 ′ of the dresser 100 for milling processing are applied to the outer diameters of the stone point 173 and the rubber point 175 being rotated by the milling machine 170. In close contact with each other, the outer diameters of the stone points 173 and the rubber points 175 of relatively low strength materials are polished at the same inclination angles as the inclination angles of the first and second dressers 130 and 130 '.

FIG. 10 is a schematic diagram showing a process of cutting a holding device 180 such as a corner telescope and a fixed attachment using a stone point / rubber point machined with a dressing machine for milling burrs according to the present invention. Although the process by 173 and the rubber point 175 is shown as one process, the surface polishing process using the rubber point 175 is performed after the primary processing using the stone point 173.

Instead of using expensive metal burs, the present invention allows the use of low-cost stone points and rubber points at the same angle as the cutting angle of metal burs to be used for the surface processing of holding devices such as corners telescopes and fixed attachments. Economical milling cutting is possible, the processing angle of the holding device can be obtained as desired, and high surface finish can be obtained.

In addition, the present invention has the effect of maintaining a constant surface quality at all times as the worn stone point and the rubber point is reworked in the first / second dresser.

In addition, the present invention allows the first / second dresser to be detachably coupled to the shaft by screwing, so that when the polishing part of the first / second dresser is worn out and cannot be used, it can be easily replaced with a new dresser. As such, maintenance and management are convenient.
