Description

  The present invention includes a machine reference surface and a cutting saw such as a circular saw or break cutter for cutting, a grooved cutter for grooving, a flooring cutter for flooring, a finger joint cutter for processing a joint portion of wood, Alternatively, the present invention relates to a blade spacer member that is interposed between the blades and adjusts the distance between the blades, and more particularly to a blade spacer member that adjusts a minute space.

Conventionally, this type of blade spacer member is used by inserting a plurality of milling bodies between the milling bodies, for example, when laminating and combining a plurality of milling bodies in the thickness direction, and adjusting the thickness of each milling body. It is used by adjusting the interval between them, or being sandwiched between a circular saw and a flange portion attached to the shaft end flange portion of the rotating device. For example, as shown in Patent Document 1, a space adjusting plate that is a spacer member is used as a mechanism for adjusting the space between two milling bodies, and the space can be adjusted by replacing the space adjusting plates with different thicknesses. It was possible. By adjusting the distance between the milling bodies, the groove width of the material to be processed is appropriately adjusted. And such an adjustment operation | work of an interval is performed by removing the nut fixed to the edge part of the main axis | shaft of the rotary cutting machine to which a milling machine is attached, and also extracting a milling body from a main axis | shaft and replacing | exchanging an interval adjustment plate.
Japanese Utility Model Publication No. 49-107794

  By the way, depending on the application of processing using the spacer member, it may be necessary to adjust the interval between the milling bodies with high accuracy such as 0.01 mm or less. For example, as shown in FIG. 16, there is a wood joint called a finger joint, and in this case, the joint members having the same shape are combined in a point-symmetric state. This joint will be described below with a simplified joint structure (a pair of grooves and protrusions) shown in FIG. In this case, if the processing shape of the left and right joint parts is inaccurate, an unnecessary gap will occur in the state where the joint parts are combined, resulting in poor joint strength or poor appearance due to loss of aesthetics. It becomes. For example, when processing of the joint portion of the wood 3 is performed with a cutter made of the milling body 1 having two blade bodies 2 having the cutting edge shape shown in FIG. 18-1, the accuracy of the milling body 1 is poor. As shown in 18-2, if the cutting areas of the two blades are misaligned, the width dimension w1 of the groove bottom of the joint portion becomes large, and the tip end width dimension w2 becomes small. When the parts are combined, they do not fit well and an undesirable gap occurs.

  Therefore, a cutter in which the main body is divided in the thickness direction is used for applications that cause such a problem. For example, a milling body is divided into two parts, and each body is formed with a blade having the same cutting edge shape. In use, the blade body of one body cuts substantially the same area as the blade body of the other milling body. Are overhanged and laminated together. Furthermore, by inserting a spacing adjustment plate between each milling body, the spacing between each milling body is adjusted, and the cutting area of each blade body is positioned so as to obtain the desired machining shape. If the adjustment is inaccurate, the cutting area of each blade is displaced, and as a result, the same problem as shown in FIG. 18-2 occurs. In this case, first, after combining, trial cutting is performed to confirm the machining shape, and when the machining shape is bad, the interval adjusting plate is replaced and further trial cutting is performed to confirm the machining shape.

  However, as described above, when it is necessary to adjust the distance with a high accuracy of 0.01 mm or less, it is necessary to repeat the above complicated procedure in order to obtain a desired processing shape because the adjustment becomes fine. Arise. In addition, since there is a limit to the types of interval adjusting plates (generally, the minimum thickness is 0.05 mm), it is not always possible to obtain a desired processing shape only by combining the interval adjusting plates. It was also necessary to work. In other words, the interval adjustment using the interval adjustment plate has a problem that it takes a lot of time together with the skill of work. Moreover, such interval adjustment is not only for newly combining milling cutters, but also when the machining shape changes due to wear of the cutting edge or the type of workpiece changes during use of the interval adjustment plate. Since it is often necessary, an adjustment method that can easily adjust the interval has been demanded.

  On the other hand, the spacer member shown in Patent Document 2 is such that two plates whose one surface is inclined at a predetermined angle with respect to the other surface are overlapped, and the entire stacked member has a uniform thickness. It is composed of two adjustment plates, and one adjustment plate of the two adjustment plates is fixed to one of a pair of milling bodies facing each other, and the other adjustment plate is attached to one adjustment plate. It is superimposed so that it can move in the tilt direction. Then, a screw screwed to be movable is provided on the blade body of one milling body, and the thickness of the interval adjusting plate can be changed by pushing or pulling and moving the other adjusting plate directly or indirectly by the screw. The interval between the pair of milling bodies is adjusted within a minute range.

The spacer member has a very small inclination angle of the overlapping surface of both adjustment plates. Therefore, the amount of change in the interval is very small with respect to the movement distance of the adjustment plate in the horizontal direction. Since it can be performed without replacement, it is possible to obtain an effect that it is not necessary to prepare many kinds of interval adjusting plates. However, in this spacer member, one adjustment plate is fixed to the milling body, and only the other adjustment plate moves, so in the milling cutter, the weight on both sides in the radial direction is biased, As a result, the rotational balance is impaired. A spacer member with a small diameter is not so much a problem, but when the radius of the milling body is increased, a large spacer member is used in accordance with the diameter, so that the milling cutter does not rotate smoothly, and therefore good cutting is performed. There is no problem.
JP 2001-191213 A

  The present invention is intended to solve the above-mentioned problem, and provides a spacer member for a blade that can easily and accurately adjust a minute interval without impairing the rotational balance of the blade regardless of the diameter of the blade. The purpose is to provide.

  In order to achieve the above object, the constitutional feature of the present invention is that there is a gap between the blade mounting surface of the machine and the blade, between the blade mounting surface of the blade holder and the blade, or between the blade and the blade. A spacer member for blades that adjusts the shape of the disk, and a base member having a disk-like shape and having a fitting recess recessed at a uniform thickness with respect to the surface excluding a predetermined portion such as an outer peripheral edge on one surface side, and one surface Is inclined at a predetermined angle with respect to the other surface, inserted into the fitting recess of the base member and movable in the inclined direction, and one surface is inclined at a predetermined angle with respect to the other surface. And a second adjustment plate that is slidably overlapped with the first adjustment plate, has a uniform thickness as a whole with the first adjustment plate, and slightly protrudes from one surface of the base member; The first adjustment plate and the second adjustment plate are moved to the opposite sides along the tilt direction. As a result, the thicknesses of the first and second adjustment plates are uniformly changed as a whole, and the movement of the first and second adjustment plates in the radial direction on both sides about the axis of the base member is made uniform. An adjustment mechanism is provided.

  In the invention configured as described above, when adjusting the distance, the first adjustment plate and the second adjustment plate that are inclined at a predetermined angle with respect to the other surface by the movement adjustment mechanism are inclined with respect to each other. Since the thicknesses of the two adjusting plates are uniformly changed as a whole by moving in the opposite direction along the, the fine interval adjustment can be easily and accurately performed. In addition, since the first and second adjustment plates have the same amount of movement on both sides in the radial direction around the axis of the base member, the balance between the weights on both sides in the radial direction of the spacer member is appropriately secured. Is done. Therefore, the rotational balance of the cutter is not impaired, and in particular, even if the outer diameter of the cutter is increased, there is no problem that cutting becomes impossible. Further, since the minute interval can be adjusted easily and accurately by the movement adjustment mechanism, the minute interval can be easily adjusted in a very short time without the need to replace the interval adjusting plate.

  In the above invention, the movement adjustment mechanism is provided with a first center hole vertically penetrating the first adjustment plate at the center of the first adjustment plate, and one side in a direction orthogonal to the inclination direction of the first center hole. Provided with a first engagement portion, a second center hole vertically penetrating the second adjustment plate at the center of the second adjustment plate, and a first direction perpendicular to the inclination direction of the second center hole. A second engagement portion is provided on the opposite side of the engagement portion, and has an annular shape and a pair of protrusions protruding radially on both outer peripheral edges in the radial direction, and is rotatable in the first and second central holes. Is provided with an interlocking member in which the pair of protrusions engage with the first and second engaging portions, and the base member is inclined in the radial direction and fitted radially through the outer peripheral edge portion. An adjustment screw that is provided with a screw hole that communicates with the mating recess, is screwed into the screw hole, protrudes into the fitting recess, and contacts the first or second adjustment plate It may be constructed by providing.

  According to this movement adjustment mechanism, the adjustment screw screwed into the screw hole provided in the radial direction at the outer peripheral edge portion in the inclination direction and the radial direction of the base member is operated, and the adjustment screw is fitted. The second adjustment plate is pushed by projecting into the recess and contacting the second adjustment plate, for example. Accordingly, the protrusion of the interlocking member that engages with the second engaging portion of the second adjustment plate is pushed, and the interlocking member rotates. Thereby, the other protrusion of the interlocking member pushes the first adjustment plate in the direction opposite to the second adjustment plate. By such movement of the first and second adjustment plates in the opposite directions of the inclination direction, the thickness of the entire first and second adjustment plates changes uniformly, thereby adjusting the thickness of the spacer member. Is done. That is, by adjusting the protrusion amount of the adjusting screw into the fitting recess, the minute thickness of the spacer member can be easily adjusted. Furthermore, since the symmetry of the weight balance of the whole spacer is maintained by the equal movement of the first and second adjustment plates in the opposite directions of the inclination direction, there is no possibility that the rotational balance of the blade is impaired.

  In the above invention, the movement adjustment mechanism is provided with a first center hole vertically penetrating the first adjustment plate at the center of the first adjustment plate, and one side in a direction orthogonal to the inclination direction of the first center hole. A first rack portion having a rack extending in an inclined direction is provided, a second central hole vertically penetrating the second adjusting plate is provided at the center of the second adjusting plate, and the second central hole is inclined in the inclined direction. A second rack portion is provided on the opposite side of the first rack portion in a direction orthogonal to the ring portion, and has a ring-shaped peripheral tooth portion extending along the circumferential direction at both outer peripheral edge positions opposed at least in the radial direction. , An interlocking member that is rotatably fitted in the first and second central holes and whose peripheral teeth engage with the first and second racks is provided, and the outer side of the base member is inclined with respect to the radial direction. A screw hole that penetrates in the radial direction in the peripheral portion and communicates with the fitting recess is provided, and the screw hole is threaded. It may also be constructed by has been provided an adjusting screw abutting on the first or the second adjustment plate projects into the fitting recess.

  According to this movement adjustment mechanism, the adjustment screw screwed into the screw hole provided in the radial direction at the outer peripheral edge portion in the inclination direction and the radial direction of the base member is operated, and the adjustment screw is fitted. The second adjustment plate is pushed by projecting into the recess and contacting the second adjustment plate, for example. Accordingly, the interlocking member rotates through the peripheral tooth portion of the interlocking member that is screwed into the second rack portion of the second adjustment plate. Accordingly, the first adjustment plate is pushed in the opposite direction to the second adjustment plate through the first rack portion of the first adjustment plate that is screwed into the peripheral tooth portion of the interlocking member. By such movement of the first and second adjustment plates in the opposite directions of the inclination direction, the thickness of the entire first and second adjustment plates is changed uniformly, and thus the thickness of the spacer member is increased. Adjustments are made. That is, by adjusting the protrusion amount of the adjusting screw into the fitting recess, the minute thickness of the spacer member can be easily adjusted. Furthermore, since the symmetry of the weight balance of the entire spacer member is maintained by the equal movement of the first and second adjustment plates in the opposite directions of the inclination direction, there is no possibility that the rotational balance of the blade will be impaired. .

  In the above movement adjusting mechanism, the first or second moving plate is adjusted by being interposed between the first adjusting plate and the second adjusting plate and biasing the first and second adjusting plates in directions opposite to each other in the inclination direction. A spring member can be provided that acts to press against the screw. Thereby, after the space | interval adjustment by an adjustment screw, since the 1st and 2nd adjustment board is in the state locked by the adjustment screw, the movement of a reverse direction warp is suppressed. Therefore, the fluctuation of the interval after the interval adjustment is surely prevented.

  In the above invention, the movement adjustment mechanism is provided with a first recess extending in the inclination direction on one side edge in a direction orthogonal to the inclination direction of the first adjustment plate and on the overlapping surface with the second adjustment plate. A first rack portion extending along the inclination direction is provided on the plane of the first recess, and a second recess is provided at a position facing the first recess on the overlapping surface of the second adjustment plate with the first adjustment plate. A second rack portion extending in the inclined direction is provided in the second concave portion so as to face the first rack portion, and penetrates in a radial direction in a side wall of the outer peripheral edge portion of the base member corresponding to the first and second concave portions. An adjustment pinion shaft hole may be provided, and an adjustment pinion member inserted through the adjustment pinion shaft hole and engaged with the first and second rack portions may be provided.

  According to this movement adjustment mechanism, the adjustment pinion member inserted in the adjustment pinion shaft hole penetrating in the radial direction provided in the side wall portion of the base member corresponding to the first and second recesses of the first and second adjustment plates is provided. By rotating, the first and second rack portions of the first and second adjustment plates engaged with the adjustment pinion member are pushed in directions opposite to each other in the inclination direction. Accordingly, the first adjustment plate and the second adjustment plate formed with the first and second rack portions are moved in directions opposite to each other in the inclination direction. By such movement of the first and second adjustment plates in the opposite directions of the inclination direction, the thickness of the entire first and second adjustment plates is changed uniformly, and thus the thickness of the spacer member is increased. Adjustments are made. That is, by adjusting the rotation amount of the adjustment pinion member, the minute thickness of the spacer member can be easily adjusted. Furthermore, since the symmetry of the weight balance in the radial direction of the entire spacer member is maintained by the equal movement of the first and second adjustment plates in the opposite directions of the inclination direction, the rotational balance of the blade is impaired. There is no fear.

  Further, as a feature of the present invention, the blade is attached to the blade attachment surface of the machine, the blade attachment surface of the blade holder or the blade through the blade spacer member according to any one of claims 1 to 5, and the blade spacer There is a blade mounting structure in which the distance between the two is adjustable by a member. According to this blade mounting structure, it is possible to precisely cut a work material using the blade whose space is appropriately adjusted by the blade spacer member.

  According to the present invention, when adjusting the distance, the movement adjustment mechanism moves the first adjustment plate and the second adjustment plate that are inclined at a predetermined angle with respect to the other surface along the inclination direction. As a result, the thicknesses of the two adjusting plates are uniformly changed as a whole, so that the minute interval adjustment can be easily and accurately performed. Furthermore, since the first and second adjustment plates have the same amount of movement on both sides in the radial direction around the axis of the base member, there is no problem that the rotational balance of the cutter is impaired. As a result, according to the present invention, even when the outer diameter of the cutter increases, smooth cutting with the cutter is ensured. In addition, the distance can be adjusted by the movement adjustment mechanism, and there is no need to replace the distance adjusting plate. Therefore, the minute distance can be adjusted easily in a very short time, and the cost for adjusting the distance can be reduced. Is greatly reduced.

  As shown in FIG. 6, the interlocking member 41 is a ring-shaped metal fitting, and includes an annular portion 42 and a pair of protrusions 43 that slightly protrude in the radial direction from the outer peripheral surface at the radial opposing positions. It is provided as a unit. The annular portion 42 has an inner diameter that is substantially the same as the outer diameter of the inner edge portion 14, is thin in the radial direction, and has an axial length that is substantially the same as the height of the inner edge portion 14. Further, one end surface in the axial direction (the upper end surface in the figure) of the annular portion 42 is axially extended within a range extending at about 80 ° C. at the central angle at a position orthogonal to the pair of projections 43. A pair of slightly recessed recesses 44 are provided.

  In the spacer member 10, the first adjustment plate 20 is fitted into the fitting recess 16 of the base member 11 and is superimposed on the bottom plate 15, and the second adjustment plate 30 is superimposed on the first adjustment plate 20. Here, the bolts 47 are screwed into the mounting small holes 29a and 29b of the first adjustment plate 20, and bolts (not shown) are screwed into the mounting small holes 39a and 39b of the second adjustment plate 30 to reduce the mounting small size. The coil spring member 46 is fixed between the holes 29a and 39a, and the coil spring member 48 is fixed between the small mounting holes 29b and 39b in a state of being extended in the longitudinal direction. As a result, the first adjustment plate 20 is pulled leftward and the second adjustment plate 30 is pulled rightward and leftward equally across the center of the base member 11 by the urging force of the coil spring members 46 and 48. . The state of the spacer member 10 shown in FIG. 1 shows a state in which the first and second adjustment plates 20 and 30 are pulled almost fully to the left and right sides, and the thickness thereof is substantially minimized.

  Next, the interlocking member 41 is fitted into the inner edge portion 14 of the base member 11 and inserted into the central holes 24 and 34 of the first and second adjustment plates 20 and 30, and the pair of protrusions 43 are connected to the first protrusion 43. The adjustment plate 20 is mounted by engaging with the engagement hole 26a of the adjustment plate 20 and the engagement hole 36b of the second adjustment plate 30. The spacer member 10 assembled in this way turns the adjusting screw 18a screwed into the screw hole 18 provided on the right side of the outer peripheral edge portion 13 of the base member 11, and pushes the second adjusting plate 30 to The entire thickness is adjusted steplessly and uniformly. Thus, as shown in FIG. 7, the spacer member 10 whose thickness is adjusted is superimposed on the flange plate 2 attached to the rotation shaft of the rotary drive device 1, and the tip saw 3 is superimposed on the outside thereof. Mounting holes (not shown) of the circular saw 4 are attached to the mounting holes 17 of the base member 11, the mounting holes 27a, 27b, 28a, 28b of the first adjusting plate 20, and the mounting holes 37a, 37b, 38a, 38b of the second adjusting plate 30. Furthermore, it is attached to the flange portion 2 by aligning with the mounting screw hole of the flange portion 2 and fixing with a bolt or the like.

  In the blade spacer member 10 of the first embodiment configured as described above, the adjustment screw 18a that is screwed into the screw hole 18 of the base member 11 is rotated to adjust the distance, thereby adjusting the screw 18a. The second adjusting plate 30 is pushed by causing the fitting recess 16 to project the proper length. Accordingly, one protrusion 43 of the interlocking member 41 that engages with the engagement hole 36b of the second adjustment plate 30 is pushed, and the interlocking member 41 rotates. Accordingly, the other protrusion 43 of the interlocking member 41 that engages with the engagement hole 26 a of the first adjustment plate 20 pushes the first adjustment plate 20 in the direction opposite to the second adjustment plate 30. In this way, by moving the first adjustment plate 20 and the second adjustment plate 30 whose one surface is inclined by a predetermined angle with respect to the other surface along the left-right direction, the two adjustment plates 20.30 can be moved. The thickness varies uniformly as a whole.
