Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cutting apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cutting apparatus for cutting a workpiece, and more particularly, to a cutting apparatus capable of precisely measuring a cutting depth while performing a cutting process on a workpiece.

In general, the cutting apparatus performs numerical control of the moving path of the cutting tool and the number of revolutions of the tool to perform cutting work on the workpiece.

At this time, the cutting tool rotates while being mounted on the spindle, and carries out cutting work on the stopped workpiece.

The higher the material removal rate (MRR) per unit time, the better the productivity. The better the surface roughness of the machined surface, the better the machining quality.

At this time, the amount of cutting per unit time is determined by the cutting condition factors such as radial cutting depth, axial cutting depth, spindle rotational speed, and feed speed. If any one of these cutting condition elements is increased, the cutting amount is increased. However, even if productivity improves, vibration noise may cause degradation of processing quality.

In addition, when the cutting tool is inserted too deeply into the workpiece, the workpiece may be damaged. Therefore, the workpiece in the field requiring precision machining such as aircraft, shipbuilding, and automobiles should be accurately checked for cutting depth while performing cutting work.

However, since it is difficult for the operator to visually confirm the cutting depth during cutting, a cutting device having a function capable of accurately measuring the cutting depth while performing the cutting operation of the workpiece is needed.

In the meantime, prior art related to the present invention is a cutting device capable of adjusting the cutting depth of Korean Laid-Open Patent Application No. 2015-0099626, comprising: a first cover surrounding at least a part of a circular blade; A second cover surrounding at least a part of the circular blade, the second cover overlapping at least a part of the first cover and having a first spring connection formed on the surface thereof; And a stopper having one end fixed to the first cover and the other end coupled to the first spring connection part and having a second spring connection part formed on the surface thereof, and a spring formed between the first spring connection part and the second spring connection part And the angle between the first cover and the second cover is adjusted as the spring is deformed according to the cutting depth.

1 to 4, a cutting apparatus 1000 capable of precisely measuring the cutting depth according to the present invention includes a case 100, a rotating shaft 200, a driving means 300, a reciprocating means 400, A fixed holder 500, a guide 610, and a cutting depth measuring means 700.

The case 100 may be formed in a cylindrical shape, and a hollow long hole (not shown) is vertically formed on the outer circumferential surface of the case 100, and the inside of the case 100 is hollowed up and down.

In addition, the case 100 is preferably made of stainless steel so as to withstand the vibrations received by the cutting tool 10, but the present invention is not limited thereto.

The rotating shaft 200 passes through the case 100 in a vertical direction, and may be formed in a cylindrical shape. At this time, a bearing (not shown) may be installed between the inner circumferential surface of the case 100 and the outer circumferential surface of the rotary shaft 200.

Also, the rotary shaft 200 is preferably made of stainless steel so as to withstand the vibrations received by the cutting tool 10, but the present invention is not limited thereto.

The driving unit 300 may include a pneumatic motor including a pneumatic hose that rotates the rotary shaft 200 and supplies air pressure to the upper end of the case 100.

The reciprocating means 400 reciprocates the rotary shaft 200 in the vertical direction.

The fixed holder 500 is coupled to the lower end of the rotary shaft 200 and has a fixing hole for fixing the cutting tool 10 (not shown) on the lower surface thereof. At this time, the cutting tool 10 can be screwed to the fixing hole.

In addition, the fixed holder 500 is preferably made of stainless steel so as to withstand the vibrations received by the cutting tool 10, but the present invention is not limited thereto.

The guide 610 has one end coupled to the rotation shaft 200 and the other end passing through the elongated hole and protruding out of the case 100.

When the rotary shaft 200 is rotated, the fixed holder 500 and the cutting tool 10 are also rotated to cut the workpiece 1. When the rotary shaft 200 is rotated and moved in the vertical direction, The holder 500 and the cutting tool 10 are rotated while being moved in the vertical direction to cut the work 1 with the movement depth of the work 1 as the cutting depth of the work 1. At this time, The guide 610 is also moved by the moving width of the fixed holder 500 and the cutting tool 10 in the vertical direction (see FIGS. 4 to 6).

That is, the moving width of the guide 610 in the up and down direction is the cutting depth at which the cutting tool 10 cuts the workpiece.

The cutting depth measuring means 700 is combined with the other end of the guide 610 to measure the vertical movement width of the guide 610. That is, the movement width of the guide 610 in the up and down direction becomes the cutting depth at which the cutting tool 10 cuts the workpiece. The cutting depth measuring means 700 measures the movement of the guide 610 in the vertical direction And the width is measured by the cutting tool 10 at the cutting depth at which the workpiece is cut.

At this time, the cutting depth measuring means measures the vertical moving width of the guide 610 (that is, the principle that the cutting tool 10 measures the cutting depth at which the workpiece is cut).

1) The rotary shaft 200 is vertically moved by using the reciprocating means 400 so that the cutting tool 10 connected to the rotary shaft 200 through the fixed holder 500 is brought into close contact with the cutting part of the workpiece .

2) Adjust the digital gauge 730 to zero.

3) Using the driving means 300, the rotary shaft 200 is rotated so that the cutting tool 10 connected to the rotary shaft 200 through the fixed holder 500 is also rotated to perform cutting of the workpiece.

4) The rotary shaft 200 is moved up and down by using the reciprocating means 400 so that the cutting tool 10 connected to the rotary shaft 200 through the fixed holder 500 is rotated by the rotary shaft 200 The guide 610 is also moved by the movement width of the rotation axis 200 in the vertical direction and the digital gauge 730 is moved in the up and down direction. Measures the movement width of the pointer 610 in the vertical direction.

The bracket 710 is separated into a first separating bracket 711 and a second separating bracket 712. The first separating bracket 711 and the second separating bracket 712 are fastened to each other .

That is, the first and second separation brackets 711 and 712 are detachably coupled to the case 100, so that the position of the first and second separation brackets 711 and 712 can be easily adjusted.

 The cutting depth measuring means 700 is provided on the opposite face of the bracket 710 facing the digital gauge 730 so as to alleviate the impact when the digital gauge 730 slides on the bracket 710 And a cushioning material 740 installed thereon.

The cushioning material 740 may be made of an elastic rubber material and mitigates an impact when the digital gauge 730 is impulsive.

The cutting depth measuring unit 700 may further include a protector 750 installed between the pair of brackets 710 such that the digital gauge 730 is disposed between the protector 750 and the case 100 .

When the digital gauge 730 hits a wall or a surrounding object due to an unexpected situation, the protector 750 may collide with the protector 750 in advance so that the digital gauge 730 is impacted It serves to prevent damage.

The reciprocating means 400 may include a rack gear 410, a pinion gear 420, and a handle 440.

The rack gear 410 is hinged to the upper end of the rotating shaft 200, and teeth are vertically formed on one surface.
