Description

  The present invention relates to a vise fixing adapter for use in fixing a vise (a vise or a horizontal vise) to a work table.

  The vise is a jig that has been used for a long time to clamp or fix a work (workpiece material) by sandwiching the work with a fixed base and a movable base. There are various types of vise, but the configuration generally called “vise (visce or horizontal vise)” has a fixed base provided integrally with a mounting base fixed to a work table, and the fixed base. It consists of a combination with a movable base that approaches and separates, and the workpiece is sandwiched between the opposing inner surfaces of the fixed base and the movable base. There is no limitation on the type of workpiece, but in the case of a workpiece (for example, wood) that is damaged when the die is directly touched, a buffer material is attached to the inner surface of the die (wood vise) as described later.

  The mounting base has an upper mounting portion and a lower mounting portion that are spaced apart from the thickness of the workbench, and a mounting female screw that screws the mounting screw shaft in a direction perpendicular to the lower surface of the upper mounting portion (usually the vertical direction). It is provided in the lower mounting portion. The mounting base has the lower surface of the upper mounting portion in contact with the upper surface of the work table, and the handle provided at the lower end of the mounting screw shaft is rotated to bring the holding plate provided at the upper end of the mounting screw shaft closer to the upper mounting portion. The work table is clamped and fixed between the lower surface of the upper mounting portion and the upper surface of the clamping plate. The mounting base rotates the handle to separate the holding plate from the upper mounting portion, releases the work table from the lower surface of the upper mounting portion and the upper surface of the holding plate, and removes the work table. Depending on the type of vise, there is also a configuration in which the mounting base is bolted directly to the work table.

  The fixed base is provided with, for example, a clamping female screw for screwing a clamping screw shaft in a direction (normally horizontal direction) orthogonal to the inner surface of the opposed movable base. The clamping screw shaft is held by a movable base provided with a movable base, and is rotated by a handle provided at an end opposite to the fixed base sandwiching the movable base. The movable base guides the advancement and retraction of the movable base by passing a guide parallel to the clamping screw shaft through the mounting base. The movable base rotates the handle, and the clamping screw shaft is screwed into the clamping female screw so as to approach the fixed base, thereby clamping and fixing the workpiece. The movable base releases the workpiece by rotating the handle and pulling the clamping screw shaft away from the clamping female screw to separate it from the fixed base. There is also a configuration in which the relationship between the fixed base and the movable base is reversed and the clamping screw shaft is held by the mounting base.

  In the case of a vise whose work is wood, a buffer material, for example, a wooden board, is attached to the inner surfaces of the fixed base and the movable base facing each other. The vise disclosed in Patent Document 1 uses a rubber magnet that is detachable from the base as a cushioning material. This is probably because the vise is made of metal (made of cast iron), and the inner surfaces of both the fixed base and the movable base that sandwich the workpiece are both iron, and the attachment / detachment using a rubber magnet is adopted. The lack of elasticity of the rubber magnet is ensured by laminating or detaching an elastic material, such as rubber or sponge, on the front side of the rubber magnet (Patent Document 1, [Claim 1] to [Claim 4]). .

JP 2007-007782 A

  In the vise, the work part or molding part of the work sandwiched between the fixed base and the movable base protrudes upward, so that the movable base is moved toward and away from the fixed base in the horizontal direction, and the work is leveled with the fixed base and the movable base. The structure is sandwiched in the direction. Such a vise configuration is preferred when the workpiece is a metal part. However, when the workpiece is wood, especially when sawing a plate material (including a square member with a rectangular cross section), the inner surface of the fixed base and the movable base are brought into contact with the narrow side edges from the horizontal direction while keeping the plate horizontal. If sandwiched between the two, the plate material is unstable, and it is not practical because the saw blade is sandwiched from the left and right. That is, when sawing at least a plate material, the conventional vise (wood vise) is not preferable.

  Here, in order to saw the plate material, it is conceivable that the movable base is moved closer to and away from the fixed base and a vise is sandwiched between the fixed base and the movable base in the vertical direction. However, this requires two types of vise for processing or forming wood including sawing of the plate material, but the two types of vise cannot be substituted for each other, so the usability is very poor. Therefore, without preparing a dedicated vise for woodworking only for sawing the plate material, according to the work ratio of sawing the plate material, move the movable base closer to and away from the fixed base other than in the horizontal direction, In order to develop a means that can choose to hold the workpiece between the fixed base and the movable base in a direction other than the horizontal direction, it was studied.

  What was developed as a result of the study tilts the posture of the vise with respect to the workbench, and causes the movable base to approach and separate away from the horizontal direction with respect to the fixed base of the vise having an upper mounting portion and a lower mounting portion on the mounting base. An auxiliary tool, wherein an upper fixing portion and a lower fixing portion are provided on the fixing base with an interval from the thickness of the work table, and a fixing female screw for screwing a fixing screw shaft in a direction perpendicular to the lower surface of the upper fixing portion is A vise that is provided on the lower fixing part and has a vise mounting part on the upper surface of the upper fixing part, and rotates the fixing screw shaft so that the clamping plate provided on the upper end of the fixing screw shaft approaches or separates from the upper fixing part. This is a fixed adapter.

  The fixed adapter according to the present invention has a vise attached to the upper mounting portion of the vise and a clamping plate provided at the upper end of the mounting screw shaft extending from the mounting female screw of the lower mounting portion. The movable base for the fixed base is fixed by sandwiching the work table between the upper fixed part provided on the fixed base and the clamping plate provided on the upper end of the fixed screw shaft extending from the fixed female screw of the lower fixed part. The approaching / separating direction is directed to a work table other than the horizontal direction, and the workpiece is sandwiched between the fixed base and the movable base other than the horizontal direction. If the vise mounting portion is orthogonal to the lower surface of the upper fixed portion, the approaching / separating direction is the vertical direction, and the work is sandwiched between the fixed base and the movable base in the vertical direction. Further, if the vise mounting portion is inclined with respect to the lower surface of the upper fixed portion, the approaching / separating direction is an arbitrary inclination direction, and the workpiece is sandwiched between the fixed base and the movable base in the arbitrary inclination direction.

  The vise mounting portion may be provided on the upper surface of the upper fixing portion separately from the fixing base, but it is preferable that the fixing base is a portion extending upward from the upper fixing portion. Thereby, the vise attached to a vise attachment part can be supported by the whole fixed base. Further, it is preferable that the upper fixing portion and the lower fixing portion are U-shaped members in front view in which end surfaces are brought into contact with the fixing base. As a result, while the upper fixing portion and the lower fixing portion are made of lightweight sheet metal, the fixing base can be provided more firmly, while the fixing base is reinforced by the orthogonal surfaces of the upper fixing portion and the lower fixing portion to improve rigidity. Can be made.

  The vise fixed adapter of the present invention inclines the position of the vise with respect to the workbench according to the angle of the vise mounting part, and moves the movable base in the horizontal direction, the vertical direction, or an arbitrary inclination direction with respect to the fixed base of the vise. It is made to approach and separate so that the workpiece can be sandwiched between the fixed base and the movable base other than in the horizontal direction. Thus, without preparing a dedicated wood vise just for sawing the plate, according to the work ratio of sawing the plate, the existing saw can be used to fix the plate using a fixed adapter. A vise suitable for pulling can be easily prepared.

  Since the fixed adapter is an auxiliary tool that mediates the vise and the workbench, it is not necessary to make the entire casting made of a solid base like a vise fixed base or a movable base, and may be made of sheet metal. In this case, when the fixed base portion is extended upward from the upper fixing portion as a vise mounting portion, or the upper fixing portion and the lower fixing portion are made into U-shaped members in front view with the end surfaces coming into contact with the fixing base portion, The strength or rigidity of the fixed adapter made can be improved.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 5, for example, the fixing adapter 1 according to the present invention connects the upper fixing portion 12 and the lower fixing portion 13 to the fixing base with a gap from the thickness of the work table 3 (see FIG. 6 and later). 11 is provided with a fixing female screw 131 for screwing the fixing screw shaft 132 in a direction perpendicular to the lower surface of the upper fixing portion 12, and the vise mounting portion 14 is provided on the upper surface of the upper fixing portion 12. The holding screw shaft 132 is turned to bring the holding plate 134 provided at the upper end of the fixing screw shaft 132 closer to or away from the upper fixing portion 12, and the work table 3 is held between the upper fixing portion 12 and the holding plate 134. Secure with.

  The fixed base 11 is made of a metal plate like a home base with the lower end horizontally cut out when viewed from the front, and the metal plate is extended upward to constitute a flush vise mounting portion 14. The fixed base 11 made of a metal plate makes the front face abut on the end surface of the work table 3 to be fixed to the fixed adapter 1 (in the fixed state, the back surface seen in FIG. 5 faces the front side. See FIG. 10. ) To secure the stability of the fixed adapter 1 with respect to the work table 3. The fixed base portion 11 of this example uses a thick metal plate to ensure the support strength of the upper fixed portion 12 and the lower fixed portion 13 and the support strength of the vise mounting portion 14 configured to extend upward. ing.

  The vise mounting portion 14 configured to extend above the fixed base 11 is provided with a pair of left and right through holes 141 and 141 communicating with mounting screw holes 221 and 221 provided in the upper mounting portion 22 of the woodworking vise 2. . Thereby, the upper mounting portion 22 is fastened with the fixing screw 142 and the fixing nut 143 (see FIG. 8 described later), and the integrity of the fixing adapter 1 and the woodworking vise 2 can be enhanced. The through holes 141, 141 in this example are circular openings on the left when viewed from the front, but are elongated holes extending left and right on the right when viewed from the front. As a result, the displacement of the mounting screw holes 221 and 221 provided in the upper mounting portion 22 of the woodworking vise 2 is absorbed, so that the fixing screw 142 can be passed through the mounting screw hole 221 and the through hole 141 together.

  The upper fixing part 12 is formed of a U-shaped metal plate with a pair of left and right flanges bent upward from the left and right edges of a rectangular web in a horizontal plan view. It abuts against the front surface of the fixed base 11, and is welded and fixed along the rear edge of the web and flange. Thereby, the lower surface of the upper fixing portion 12 (the lower surface of the web) is orthogonal to the front surface of the fixing base portion 11 and also orthogonal to the vise mounting portion 14 that is an extension portion of the fixing base portion 11. The upper fixing portion 12 of this example is provided with a work opening 121 large enough to allow the clamping plate 134 to pass therethrough for screwing operation when the funnel-shaped clamping plate 134 is attached to the upper end of the fixing screw shaft (FIG. 3). Since the upper fixing portion 12 makes the lower surface abut on the upper surface of the work table 3, the problem of strength reduction due to the provision of the work opening 121 does not occur.

  Here, when the weld bead appears on the lower surface (the lower surface of the web) of the upper fixing portion 12, the weld bead interferes with the end surface or the upper surface of the work table 3, and the front surface of the fixing base 11 or the lower surface of the upper fixing portion 12 is It cannot be in close contact with the end surface or upper surface of the work table 3, resulting in an unstable mounting state. Therefore, the upper fixing portion 12 may be welded to the fixing base portion 11 from the upper surface side of the web so that the weld bead appears on the upper surface of the web. Further, the flange weld bead has no problem like the web weld bead. However, from the viewpoint of simplifying the welding operation, the weld bead is welded from the inside sandwiched between the pair of left and right flanges continuously from the web welding. Should appear on the inside. As a result, the weld bead of the upper fixed portion is hardly visible from the outside, and an advantage that the aesthetics as the fixed adapter 1 is improved is obtained.

  The lower fixing portion 13 is formed of a substantially U-shaped metal plate that is bent upward from left and right edges of a horizontal trapezoidal web (see FIG. 4) and includes a pair of left and right flanges. The long rear edge and the rear edge of the flange are abutted against the front surface of the fixed base 11, and are welded and fixed along the rear edge of the web and the flange. Since the lower fixing portion 13 does not directly contact the work table 3, there is no problem of the weld bead as in the above-described upper fixing portion 12, but it makes it difficult to visually recognize the weld bead and the aesthetic property as the fixing adapter 1 is improved. From the viewpoint of improvement, welding is preferably performed from the inside surrounded by the web and the pair of left and right flanges so that the weld bead appears only on the inside.

  The lower fixing portion 13 of this example is provided with an opening penetrating vertically in the center of the upper surface of the web, and a nut communicating with the opening is fixed by welding, and the nut is used as a fixing female screw 131. The fixed screw shaft 132 extends vertically while sandwiching the fixed female screw 131 while being screwed to the fixed female screw 131. The holding plate 134 made of a funnel-shaped metal plate is screwed to the upper end and orthogonal to the lower end. Then, a handle 133 that can freely advance and retract in the radial direction is attached. The fixed screw shaft 132 rotates the handle 133 horizontally to rotate, changes the screwing position with respect to the fixed female screw 131, and moves the upper clamping plate 134 closer to or away from the lower surface of the upper fixing portion 12.

  The fixed adapter 1 of this example has a movable base 25 approaching and moving away from the work table 3 in a direction perpendicular to the fixed base 24 of the woodworking vise 2 in particular. ) In the vertical direction. As shown in FIG. 6, for example, the vise 2 for woodworking has an upper mounting portion 22 and a lower mounting portion 23 mounting base 21 that are spaced apart from the thickness of the work table 3, and screwed with a mounting screw shaft 232. A mounting female screw 231 is provided on the lower mounting portion 23. The attachment screw shaft 232 is provided with a handle 233 at the lower end (in the posture of FIG. 6), and a funnel-shaped holding plate 234 provided at the upper end (in the posture of FIG. 6) approaches or separates from the upper attachment portion.

  The fixed base 24 is configured as an extension of the mounting base 21, and a clamping female screw 242 is provided on the mounting base 21 to which a clamping screw shaft 252 is screwed in a direction perpendicular to the inner surface of the opposed movable base 25. . The clamping screw shaft 252 is held by a movable base (a downward extension of the movable base 25) integrated with the movable base 25, and is rotated by a handle 253 provided at an end opposite to the fixed base 24 with the movable base 25 interposed therebetween. Is operated. The movable base guides the advancement and retraction of the movable base 25 by penetrating guides 254 and 254 (see FIG. 10) parallel to the holding screw shaft 252 through the attachment base 21. The fixed base 24 and the movable base 25 are provided with wooden plates 241 and 251 as cushioning materials on inner surfaces facing each other. In addition, the movable base 25 of this example is provided with an anvil 243.

  The procedure for fixing the wood vise 2 using the fixing adapter 1 of this example will be described. First, the woodworking vise 2 is attached to the fixed adapter 1. Specifically, as shown in FIG. 7, the woodworking vise 2 is tilted 90 degrees from the normal use state (see FIG. 6) with respect to the fixed adapter 1 with the fixed base 11 aligned in the vertical direction. The vise mounting portion 14 of the fixed adapter 1 is sandwiched between the upper mounting portion 22 and the clamping plate 234 of the woodworking vise 2. In order to stably attach the woodworking vise 2 to the fixed adapter 1 of this example, as shown in FIG. 8, the through-hole 141 provided in the vise mounting portion 14 and the mounting screw hole 221 of the upper mounting portion 22 The vise mounting portion 14 and the upper mounting portion 22 are integrated with each other by inserting a fixing screw 142 and tightening with a fixing nut 143.

  As shown in FIGS. 9 and 10, the wood vise 2 attached to the fixed adapter 1 is provided on the fixed base 11 by bringing the front surface of the fixed base 11 of the fixed adapter 1 into contact with the end surface of the work table 3. The work base 3 is fixed with the upper fixing portion 12 and the holding plate 134 provided at the upper end of the fixing screw shaft 132 extending from the fixing female screw 131 of the lower fixing portion 13, and the movable base 25 approaches the fixed base 24. The separation direction is directed to the vertical direction with respect to the work table 3 (FIG. 6 and FIG. 9 are compared). As a result, a wide plane (upper surface and lower surface) of the wooden plate material (work, not shown) is held in a horizontal position with the fixed base 24 and the movable base 25 of the vise 2 for woodworking vertically, that is, the saw blade is vertically moved The plate material protruding in the horizontal direction from the fixed base 24 and the movable base 25 can be easily sawed.

  The vise 2 for woodworking simply clamps the vise mounting part 14 of the fixing adapter 1 with the upper mounting part 22 and the clamping plate 234 and tightens it with the fixing screw 142 and the fixing nut 143. If the holding plate 234 is moved away from the upper mounting portion 22 by rotating the shaft 232, the fixing adapter 1 can be removed while being fixed to the work table 3. If the plate material is only to be sawed in a horizontal position, it may be possible to construct a dedicated vise for woodworking in which the movable base approaches and separates in the vertical direction with respect to the fixed base, but the fixed adapter 1 of the present invention is used. For example, while using the existing vise 2 for woodworking as it is, the movable base 25 is moved away from the fixed base 24 in the horizontal direction or the vertical direction according to the work ratio of sawing the plate material, and the fixed base and the movable base With this, it is possible to select to sandwich the plate material (workpiece) in the horizontal direction or the vertical direction.

  In the fixed adapter 1 of this example, since the vise mounting part 14 is orthogonal to the lower surface of the upper fixing part 12, the fixed base 24 and the movable base of the wood vise 2 attached to the vise mounting part 14 25 approaching and separating directions became vertical. For this reason, if the fixed adapter 1 of this example is not used, the wood vise 2 sandwiches the plate (work) horizontally between the fixed base 24 and the movable base 25 (see FIG. 6), and the fixed adapter of this example If 1 was used, the board | plate material (workpiece | work) could be pinched | interposed in the perpendicular direction. From now on, for example, as shown in FIG. 11, if the vise mounting portion 14 is inclined with respect to the lower surface of the upper fixing portion 12, the approaching and separating directions of the fixed base 24 and the movable base 25 of the vise 2 for woodworking will be described. The plate material (workpiece) can be sandwiched between the fixed base 24 and the movable base 25 in an arbitrary inclination direction. In this case, when the vise mounting portion 14 is inclined toward the upper fixing portion 12, the handle 233 for tightening the clamping plate 234 of the woodworking vise 2 becomes difficult to operate. It is good to incline in the direction away from (see Fig. 11).
