Abstract

(57) [Summary] [Object] The present invention relates to a tool mounting device for a tool barrel of a planing machine, and is to facilitate the mounting and dismounting work of the tool and improve the mounting accuracy. [Constitution] According to the present invention, when a groove 4 for the number of blades is axially engraved in a tool barrel 1 and a tool 5 and a back blade 6 fixed in a state where the cutting edge is adjusted are inserted into each groove 4, A wedge-shaped gap is formed in the axial direction, and the wedge 7 is attached thereto. A nut 8 is attached to one end of the tool barrel 1, and the surface of the nut 8 engages with the surface of the wedge 7 so as to interlock in the axial direction. A ring 9 is fitted to the other end of the tool barrel 1, and when the nut 8 is moved to the wedge 7 side by a tightening operation, each wedge 7 interlocks to press the back blade 6 to fix the tool 5.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a blade fixing device for a planer.

[0002]

[Prior Art]

 As shown in FIG. 5 and FIG. 6, the blade bodies of the conventional planing boards fix the individual blades 5 to the blade body 1 with a plurality of bolts 10.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional technique, a large number of bolts 10 that are operated to attach and detach the blade 5 are required, and the attachment and detachment of the blade 5 is troublesome. Moreover, since the fixing process is divided for each blade 5, the accuracy of the blade tip adjustment becomes poor. An object of the present invention is to improve workability in attaching / detaching a blade of a planer and improving mounting accuracy between the blades by facilitating attachment / detachment of the blade.

[0004]

[Means for Solving the Problems]

 In the planer body of the planer, one end of a wedge corresponding to each tool is engaged with an axially movable nut that is attached to one end of the planer, and the back blade is pressed to simultaneously engage each tool by axially interlocking. Achieve by fixing.

[0005]

[Action]

 When the nut mounted on the end of the tool barrel is moved in the axial direction as in the above means, the wedges work together to press the back blade and fix the tool at the same time. If the nut is moved in the opposite direction, the wedge will loosen and the blade will be unlocked.

【Example】

 An embodiment of the present invention will be described with reference to FIGS. 1 is a front view showing an embodiment of the present invention, FIG. 2 is a right side view of FIG. 1, FIG. 3 is a sectional view taken along line AA of FIG. 1, and FIG. 4 is an enlarged view of portion B of FIG. In the figure, reference numeral 1 denotes a tool barrel, both ends of which are axially supported by bearings 2, and a driven pulley 3 is fitted to one end. Grooves 4 corresponding to the number of blades are formed in the tool barrel 1 in the axial direction, and the surfaces 4a and 4b form a wedge-shaped space having a narrow radial outer side. The surface 4a is also inclined in the axial direction, and when the blade 5 and the back blade 6 fixed in the groove 4 in the adjusted state are inserted, a wedge-shaped gap is formed in the axial direction. The wedge 7 is attached here. A nut 8 is attached to one end of the tool barrel 1, and in FIG. 4, the surfaces 8a and 8b are axially interlocked by engaging the surfaces 7a and 7b of the wedge 7, respectively. A ring 9 is fitted to the other end of the tool body 1 to form an axial abutting surface 9a of the back blade 6 and an inner surface 9b for supporting the wedge 7 and the back blade 6 in the radial direction. In the above structure, the work for attaching the blade 5 is performed as follows. The blade 5 is fixed to the back blade 6 by adjusting the cutting edge. This is done by installing bolts 10 at both ends. When the nut 8 is moved in the axial end direction, both ends of the back blade 6 are hooked to the nut 8 and the ring inner surface 9b, respectively, and after temporarily fixing all of them, the nut 8 is moved to the wedge 7 side. The back blade 6 is pressed together to fix the blade 5. When removing the blade 5, the nut 8 is moved in the opposite direction to loosen the wedge 7, and the blade 5 is released from the fixed state.

[0007]

[Effect of the device]

 According to the present invention, in a conventional blade attaching / detaching operation, since a large number of fixed bolts that have been operated are fixed by one nut at the same time, all the blades can be fixed at the same time, which improves workability. Further, fixing the blades at the same time improves the mounting accuracy between the blades as compared with fixing the blades individually.
