Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tool holder for a superfinishing planer that finish-cuts the surface of wood.

[0002]

[Prior art]

 A conventional example will be described with reference to FIG. FIG. 8 is a sectional view of the tool post. The planer blade 4 is sandwiched between the holders 2 and 3 and fixed with bolts 5. A tool mounting surface 1a is formed on the tool rest 1, and the holders 2 and 3 are fixed to the tool mounting surface 1a with a fixing bolt 7 via a disc spring 6. An adjusting screw 8 is provided behind the holders 2 and 3 of the tool rest 1, and a tip portion 8a of the adjusting screw 8 is mounted in a groove 2a formed on a lower surface of a rear portion of the holder 2, and when the adjusting screw 8 is rotated, the holder 8 is rotated. 2 and 3 move in the C direction. When exchanging the planer blade 4, first, the fixing bolt 7 is removed, and the holders 2, 3, the planer blade 4 and the bolt 5 are removed from the tool rest 1 in an assembled state. Further, loosen the bolt 5 and pull out the planer blade 4 from the holders 2 and 3. To attach the planer blade 4, reverse the above removal procedure.

[0003]

[Problems to be solved by the device]

 As described above, when exchanging the planer blade 4, it is necessary to remove the holders 2 and 3 from the tool rest 1, further loosen the bolts 5 and remove the planer blade 4 from the holders 2 and 3, which requires time for replacement. I needed it. An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and simplify the replacement of the planer blade.

[0004]

[Means for Solving the Problems]

 In the present invention, several springs are provided between the holders, and the springs are provided at positions where the mounting portion of the planer blade is forcibly opened. The holders were combined by forming protrusions on the upper surfaces of both ends of the one holder, forming through-holes in the holders located above, and forming protrusions on both sides of the planer blade. In this state, the planer blade is held between the holders by inserting the planer blade through the through hole of the holder and bringing the projection of the planer blade into contact with the convex portion.

[0005]

[Action]

 To remove the planer blade from the holder constructed as described above, first loosen the bolt while holding the holder on the tool rest. As a result, the holders are forcibly opened by the springs provided between the holders, and the holding of the planer blade is released. In this state, pull out the planer blade. To install the planer blade, insert the planer blade through the hole in the holder, hold the protrusions on both sides of the holder against the protrusions on both sides of the planer, and hold it with a bolt.

[0006]

【Example】

 An embodiment of the present invention will be described with reference to FIGS. 1 is a cross-sectional view of a state in which the planer blade 4 is attached to a holder and fixed to a tool rest, FIG. 2 is a view seen from the direction A in FIG. 1, FIG. 3 is a plan view of the planer blade, and FIG. It is a BB sectional drawing of FIG. In FIG. 1, a tool mounting surface 1a having an inclined surface is formed on one side of a tool rest 1, and a tool tip 10 is attached to the other by a bolt 11. In FIG. 2, convex portions 3a and through holes 3b are formed at both ends of the lower surface of the holder 3, and projections 4a are formed on both side surfaces of the planer blade 4 as shown in FIG. In the state where the holders 2 and 3 are combined, the planer blade 4 is inserted from the through hole 3b of the holder 3, the projection 4a of the planer blade 4 abuts the convex portion 3a, and the planer blade 4 holds the holder 2 and 3. Holds between three. The holders 2 and 3 are fixed with bolts 5, the planer blade 4 is sandwiched between the holders 2 and 3, and the holders 2 and 3 are attached to the blade mounting surface 1a with the fixing bolts 7 via the disc springs 6. To be A recessed groove 2a is formed on the lower surface of the rear part of the holding tool 2 (opposite to the cutting edge), an adjusting screw 8 is provided behind the holding tools 2 and 3 of the tool rest 1, and the tip portion 8a of the adjusting screw 8 is formed in the groove 2a. It is engaged. When adjusting the position of the cutting edge of the planer blade 4, the adjusting screw 8 is rotated to move the holders 2 and 3 back and forth. Several holes 2c are formed in the rear of the upper surface of the holder 2 (in this embodiment, two holes are formed at both ends), and the holder 3 has holes 3c at positions corresponding to the holes 2c. Has been formed. Inside the holes 2c and 3c, a spring 9 having an urging force for opening the tips of the holders 2 and 3 is provided. 5 is a sectional view showing a state in which the holder is opened, and FIG. 6 is a sectional view showing a state in which the planer blade 4 is taken out. In the above structure, when the bolt 5 is loosened as shown in FIG. 5, the holding tool 3 is opened by the spring 9, and the planer blade 4 can be taken out as shown in FIG. FIG. 7 is a sectional view showing a state in which the planer blade is attached to the holder. To attach the planer blade 4, tighten the bolts 5 slightly as shown in FIG. The planer blade 4 is inserted through the through hole 3b of the tool 3. After mounting the planer blade 4, hold the planer blade 4 with the bolt 5. Therefore, it is not necessary to remove the holding bolts 2 and 3 from the tool rest 1 by removing the fixing bolt 7, and only by loosening the bolt 5, the planer blade 4 can be replaced.

[0007]

[Effect of device]

 According to the present invention, because of the above-described configuration, it is not necessary to remove the holder from the tool rest when replacing the planer blade, so that the planer blade can be replaced easily and quickly.
