Definitions

  • the present invention relates to a deburring and chamfering tool, and more particularly to a tool capable of continuously deburring and chamfering the front and back of a workpiece.
  • Machined products and cast products generally have burrs at their corners, etc., so they cannot function as they are, and there is a risk of injury if touched.
  • An object of the present invention is to provide a deburring and chamfering tool that can easily automate deburring and chamfering.
  • the first spring and the second spring have a bi-directional extension mechanism
  • the first spring and the second spring are respectively K ⁇ F 0 ⁇ H / ⁇ L Having a spring constant K (N / mm) satisfying
  • F 0 is a standard set load (N)
  • H is a load change value (%)
  • ⁇ L is a length direction change value (mm)
  • H is 10% or less.
  • the cutting edge or the file portion of the deburring and chamfering tool is made of a “abacus” shaped cemented carbide.
  • the load change is small and the processed surface after deburring can be made uniform.
  • the deburring and chamfering tool of the present invention has an expansion / contraction mechanism in both directions, the front and back of the workpiece can be worked with one deburring and chamfering tool.
  • the deburring and chamfering tool of the present invention does not require adjustment of the spring force, and a tool suitable for the material and chamfering size of the workpiece can be easily selected.
  • Cast burr has uneven unevenness, making it difficult to program for machining. Therefore, the deburring tool needs to have a flexible extension / contraction mechanism. With the expansion and contraction mechanism, a safe and clean processed surface can be obtained with a simple program.
  • the expansion / contraction mechanism is required to have a small load change due to expansion / contraction from the viewpoint of usability.
  • FIG. 1 is a cross-sectional view showing a configuration of a deburring and chamfering tool 100 according to the present invention.
  • the deburring and chamfering tool 100 is attached to the shank 1 which is a connecting means between the main body 2 and a drive motor or a tool holder attached to the left of the main body 2 in the figure, and to the right of the main body 2 in the figure.
  • the cutting tool 13 is fixed to the main body by a taper collet 11 and a nut 10.
  • the first spring 4 is a compression coil spring and is disposed between the spring receiver 7 and the main body 2
  • the second spring 5 is a tension coil spring and is disposed between the spring receiver 7 and the main body 2.
  • the set load is set by the combination of the first spring 4 and the second spring 5.
  • the first spring 4 and the second spring 5 are respectively K ⁇ F 0 ⁇ H / ⁇ L Having a spring constant K (N / mm) satisfying
  • F 0 is a standard set load (N)
  • H is a load change value (%)

  • Fig. 2 (a) shows the processing of the surface burr of the workpiece
  • Fig. 2 (b) shows the processing of the surface burr of the workpiece.
  • FIG. 3 is a view for explaining the movement of the cutting edge or the file portion 12 relative to the workpiece (workpiece) 20 according to the embodiment of the present invention.
  • the shape of the workpiece is simplified as shown on the left in the figure.
  • a workpiece has front and back burrs by machining and casting.
  • the cutting edge or file portion 12 of the present application is made of a cemented carbide material having an “abacus bead” shape, and can correspond to both front and back burrs as shown on the right side of the figure.
  • the front burr corresponds to the lower side of the “abacus pearl” shape
  • the back burr corresponds to the upper side of the “abacus pearl” shape.
  • the ability to handle both front and back burrs using the abacus-shaped cutting edge or file 12 is achieved by having the bi-directional expansion and contraction mechanism described above.
  • the deburring and chamfering tool of the present invention is a method of facilitating a tool adjusted to several kinds of set loads so as to adapt to various machining conditions, and selecting a tool according to the workpiece material, chamfer size, etc. .

  • FIG. 5 is a graph for selecting a tool from the hardness and chamfer size of the workpiece material
  • FIG. 6 is a tensile strength and chamfer of the workpiece material. It is a graph for selecting a tool from the size.
  • the graphs of FIGS. 4 to 6 show tools adjusted to four types of set loads, and tools adjusted to the highest set load or the lowest set load in order from the top.
  • the types of set loads are not limited to four.
  • the optimum deburring and chamfering tool 100 is selected from these graphs based on the material and the chamfer size. Since the deburring and chamfering tool 100 of the present invention is color-coded for each set load, the deburring and chamfering tool 100 having a desired set load can be selected without mistake.
  • the load change is small, the processed surface after deburring can be made uniform, Since the deburring and chamfering tool of the present invention has an expansion and contraction mechanism in both directions, the front and back of the workpiece can be worked with one deburring and chamfering tool, There is no need to adjust the spring force, and it is possible to easily select a tool suitable for the material and chamfer size of the workpiece.
