Description

The present invention relates to a base used for a work vice apparatus for holding a workpiece in machining, and a vise apparatus for a 5-axis machining apparatus using the base.

  Vise devices are widely used as devices for fixing a workpiece to a table of a machine tool when machining the workpiece with a machine tool. Such a vise device is provided with a pair of jaws (jaws) that move in directions close to and away from each other by a driving device such as a feed screw or a hydraulic cylinder, and the jaws are usually made of a flat metal plate made of hard metal. (Hard base) or a base (raw base) having a gripping surface adapted to the shape of the work is attached, and the opposite side surface of the work is gripped and fixed by the base.

  In the field of machining, in order to reduce costs, it is required to speed up processing, shorten setup time, consolidate processes, etc. In recent years, the introduction of 5-axis machines has been promoted. ing. With this 5-axis machine, only the bottom surface of the workpiece being clamped can be machined, and the other 5 surfaces can be machined. Therefore, all surfaces of the workpiece can be machined with a single change. It becomes possible. When performing the intended machining using such a 5-axis machine, it is necessary to prevent the spindle of the machine or the machining tool from interfering with the vise device, and in particular, the machining surface of the workpiece on the side to be sandwiched Must be secured sufficiently wide.

  Japanese Patent Application Laid-Open No. 2008-264983 proposes a machine vise for a 5-axis machine. In this document, a machine vise suitable for a five-face processing machine that effectively prevents an opening between two movable jaws that clamp a workpiece while avoiding interference with a spindle of a processing machine and a processing blade. Has proposed. Specifically, in the double clamp type vise, the female screw sleeve is mounted non-rotatably around the axis at the upper part of the first movable jaw and below the stepped part, while at the upper part of the second movable jaw. The bolt is rotatably mounted around the axis below the stepped portion, and the female screw sleeve and the bolt are prevented from freely moving in a direction approaching the other movable jaw from the respective movable jaw. However, it is attached so as to allow free movement in the direction of separation, and the female screw sleeve and the bolt are screwed together so as to prevent the opening when the workpiece is clamped between the movable jaws. It is configured.

In the past, a technique related to a base structure of a vise that holds a workpiece has also been proposed. For example, in Patent Document 2 (Japanese Patent Laid-Open No. 7-299758), when attaching a base to a vise, it can be easily attached without removing the base of the main body, and both front and back sides of the base can be used. As a vise base structure, two bolt mounting holes on the left and right are provided at the center of the base of the base bolted to the vice body, and two bolts on the left and right at the center of the base of the base to correspond to the bolt mounting hole of the base. It is disclosed that an insertion hole is provided and the raw base is fastened to the front surface of the base with fastening bolts.

JP 2008-264983 A JP-A-7-299758

  In the past, when machining a workpiece held by a vice device, it is known that it is necessary to prevent the spindle of the processing machine and the cutting tool from interfering with the vise device, and a machine for a 5-axis processing machine. Vice devices have also been proposed. The work was also held by a base attached to the jaw of the vise device.

  However, the conventionally used base is used to securely hold the workpiece, and does not solve the problem of interference with the spindle of the processing machine or the processing blade when used in a 5-axis processing machine. There wasn't.

Therefore, in the present invention, a first object is to provide a vise device base capable of solving the problem of interference with the spindle of a processing machine and a processing blade, and a vise device for a 5-axis processing machine using the same. Let it be an issue Furthermore, it is a first object of the present invention to provide a base for a vise device that can be used as a vise device for a 5-axis machining machine that can be used in a 5-axis machine by being installed in a vise device for a 3-axis machine. Let it be the second issue.

  In order to solve at least one of the above-mentioned problems, in the present invention, a base of a vise device used for fixing a work to a table or pallet of a machine tool, and a vise device for a 5-axis processing machine configured using the same are provided. It is to provide.

  That is, the base for a vise apparatus according to the present invention is a base for a vise apparatus used in a vise apparatus having a pair of jaws that are close to and away from each other, and the base is attached to the jaw to hold a workpiece. In addition to the holding surface, the back surface side of the holding surface is inclined so as to taper upward (ie, in a direction away from the table surface on which the vice apparatus is provided).

  Since the back side of the base is tapered upwardly, the base for the vise apparatus does not interfere with the spindle of the processing machine or the processing blade even when machining with a machine tool. The problem can be solved.

  In the vise device base, the clamping surface is configured to clamp a side surface of a workpiece (hereinafter also referred to as “workpiece”). And the said holding surface can be formed as a surface perpendicular | vertical with respect to the table surface (or upper surface of the base in which a jaw is provided) in which a vice apparatus is provided. Thereby, a workpiece | work can be clamped with an equal force in the height direction, and a workpiece | work can be hold | maintained in the stable state.

  Further, the side surface of the holding surface can also be formed to be inclined so as to taper upward. By forming the vice device base in a tapered shape in the width direction, even when the workpiece is processed by rotating the vice device, the vise device base may interfere with the spindle of the processing machine or the processing blade. Disappear. At this time, only one of the side surfaces of the base for the vice apparatus can be formed so that the upper side is narrowed. Thereby, it is possible to make it easier to perform the processing from the inclined side surface while strongly maintaining the clamping force of the workpiece.

  In the base for a vice apparatus according to the present invention, an upper cutout portion cut out in a step shape can be provided above the holding surface. By providing such an upper cut-out portion, the lower surface of the workpiece to be processed can be supported, and the workpiece can be clamped more reliably. The height of the upper notch can be arbitrarily adjusted by installing a parallel plate formed in the upper notch as a plate having a thickness that compensates for the upper notch.

  In the base for a vice apparatus according to the present invention, it is desirable to provide a scale for positioning the workpiece on the upper surface of the holding surface (that is, the upper surface of the base for the vise apparatus). The workpiece to be processed is sandwiched between a pair of vise device caps, and the scale is provided, so that the workpiece can be held at the center of the vice device cap while watching this. As a result, the force held by the vise device base is not biased to any part of the workpiece, and can be held with an equal force.

  Further, in the base for a vice apparatus according to the present invention, the lower surface of the holding surface (that is, the lower surface of the base for the vice apparatus) forms a lower surface notch portion covering the opposing surface and the upper surface of a pair of jaws formed in a rectangular parallelepiped. It is desirable to do. The lower surface notch is formed by notching the lower surface of the vise device base in a step shape toward the back side, and forming the lower surface in a groove shape to accommodate the jaws. Can do. By providing the lower surface notch portion, the vise device base can be securely fixed to the jaw of the vise device. In particular, the vise device base can exist so as to cover the opposing surface side (the surface in the holding direction) of the jaw, so that even when the workpiece is held with a strong force, the vise device base is displaced. And distortion can be reduced as much as possible.

And in this invention, the vice apparatus comprised using the said nozzle | cap | die for vise apparatus is provided. That is, a vise apparatus that attaches a pair of bases that grip both side surfaces of a workpiece to a pair of jaws that are close to and away from each other, and grips the workpiece with the pair of bases by the proximity movement of the pair of jaws, The device base provides a vise device which is the vice device base according to the present invention. A base for a vice apparatus used in the vise apparatus is a base for a vice apparatus according to the present invention, and is formed in a tapered shape in a direction away from a table surface on which the vise apparatus is provided. 5-axis processing machine that can be used favorably in a 5-axis processing machine that controls workpieces by controlling two tilting axes in addition to the three axes of left, right, front, back, and top and bottom. Vice device.

  The base for a vice apparatus of the present invention can solve the problem of interference with the main spindle of a processing machine and a processing blade. Therefore, even in a 5-axis machining apparatus capable of machining while tilting the workpiece, it is possible to provide a vise apparatus for a 5-axis machining apparatus that solves the problem of interference with the spindle of the machining machine and the machining blade.

In addition, the base for a vice apparatus according to the present invention can be used by being attached to a jaw of a vise apparatus for a 3-axis processing machine, whereby the vise apparatus for a 3-axis processing machine is used as a vise apparatus for a 5-axis processing machine.

  Hereinafter, with reference to the drawings, a vise apparatus base 10 according to the present embodiment and a vice apparatus for a 5-axis machining apparatus using the same will be described in detail. In particular, the base 10 for a vise apparatus according to the present embodiment is a base 10 for a vise apparatus that is attached to a vise apparatus for a three-axis processing machine and can be suitably used in a five-axis processing machine.

  FIG. 1 is a six-side view showing a vise device base 10 according to a first embodiment, wherein (A) a rear view, (B) a plan view, (C) a front view, (D) a right side view, E) Bottom view, (F) FF longitudinal sectional view. 2A is a perspective view of the base 10 for a vise apparatus according to this embodiment, as viewed from above the rear surface, and FIG. 2B is a perspective view of the base device 10 as viewed from above the front surface. FIG. 4 is a perspective view showing a state in which the plate 16 is installed, FIG. 4 is a longitudinal sectional view according to another embodiment showing a state in which the parallel plate 16 is installed, and FIG. 5 shows the vise device base 10 as a vise device. FIG. 6 is a longitudinal sectional view showing a state where the jaw 20 is installed.

  The vise device base 10 according to this embodiment has a front surface formed as a holding surface 17 for holding a workpiece to be processed. The holding surface 17 is formed as a surface perpendicular to the table surface 22 (or the base 21 of the vice device) on which the vice device is provided. Further, an upper cutout portion 13 cut out in a step shape is provided above the holding surface 17. This upper notch 13 can be used for supporting the bottom surface of the workpiece to be machined and positioning in the height direction.

  Moreover, since the workpieces to be machined have various shapes and the machining parts are also varied, the position and area supported by the vice apparatus are usually different depending on the workpieces. Therefore, in the vise device base 10 according to the present embodiment, as shown in FIG. 3, a parallel plate 16 is installed in the upper notch 13 to adjust the height of the upper notch 13. Can do. Thereby, the height which hold | maintains a workpiece | work can be adjusted and it can hold | grip for various workpiece | works. In particular, the parallel plate 16 can be formed as a flat surface so as not to leave a trace on the workpiece. On the other hand, there is no problem even if a trace is generated on the workpiece. If desired, a convex portion can be formed on the holding surface 17 side of the parallel plate 16. As a result, the gripping force concentrates on the convex portion, and the workpiece gripping force can be increased.

  The parallel plate 16 is formed as a plate having a thickness capable of supporting the bottom surface of the workpiece, and the upper end surface of the parallel plate 16 is formed as a flat surface, and in accordance with the bottom surface shape of the workpiece to be held, It can be formed in a shape that complementarily engages.

  The parallel plate 16 may be formed to have the same thickness as the depth of the upper notch 13 (that is, the depth recessed from the holding surface 17) or thinner than the depth of the upper notch 13. it can. As a result, the weight of the workpiece can act straight on the bottom surface of the upper cutout portion 13, and the possibility that the parallel plate 16 falls off the upper cutout portion 13 can be eliminated.

  Further, in order to prevent the parallel plate 16 installed in the upper cutout portion 13 from dropping off, at least one of the upper cutout portion 13 and the parallel plate 16 has a magnetic force and is magnetically attached to the other. Can be formed. Alternatively, the parallel plate 16 and the upper cutout portion 13 can be attached, or a structure portion in which both are complementarily joined or occluded can be formed.

  In particular, when the upper notch 13 and the parallel plate 16 are coupled by a magnetic force, the workpiece is a magnetic material. When the workpiece is cut, the cutting scrap (or metal scrap) also adheres. It is possible. Therefore, it is desirable that the parallel plate 16 has a magnetic force and the vise device base 10 is made of a ferromagnetic material so that the attached cutting waste can be removed without difficulty.

  Further, in order to prevent the parallel plate 16 from falling off from the upper cutout portion 13, when forming a structure portion that is complementarily joined or engaged with both, the structure portion is as shown in FIG. 4. Further, it can be formed on the lower surface of the parallel plate 16 and the bottom surface of the upper notch 13. 4A, the bottom surface of the upper notch 13 is formed as a substantially V-shaped groove that is inclined downward in the depth direction, and the bottom surface of the parallel plate 16 is substantially V-shaped. The embodiment formed in the wedge shape which fits into a groove | channel is shown. When the upper notch 13 and the parallel plate 16 are formed in this way, the parallel plate 16 is supported by the substantially V-shaped groove, so that the parallel plate 16 is prevented from falling or falling off as much as possible. Can do. 4B, a concave groove is formed in the depth direction of the bottom surface of the upper cutout portion 13, and a convex portion that fits into the concave groove is formed on the bottom surface of the parallel plate 16. FIG. When the upper notch 13 and the parallel plate 16 are formed in this way, the parallel plate 16 can be prevented from moving in the thickness direction. The risk of falling off can be reduced as much as possible. However, when the workpiece is directly supported by the upper notch 13, it is desirable that the lower surface (lower surface in the height direction) of the upper notch 13 is formed flat. This is to prevent the generation of traces on the lower surface of the workpiece.

  In the vice apparatus base 10 according to the present embodiment, the back surface side of the holding surface 17 (or the vice apparatus base 10) is inclined so as to be narrowed upward. That is, the back surface is inclined so as to become thicker in the downward direction so as to spread outward, and as a whole, the vertical cross-sectional shape is a wedge shape or a trapezoidal shape. A vertical rising surface is formed on the lower side of the rear surface so as to make the inclination of the inclined surface gentle and ensure the thickness of the base 10 for the vice apparatus. Since the thickness of the vise device base 10 is secured, it is possible to prevent the vise device base 10 from being distorted and deformed, and to hold the workpiece reliably even when a force is applied by a processing machine. it can.

  As described above, by tilting the back surface of the vise device base 10, the main spindle of the processing machine and the processing blade do not interfere with the jaw 20 and the base of the vise device, which is also suitable for a 5-axis processing machine. A vice device that can be used in the future is realized. In particular, since the base 10 for the vise apparatus is formed widely in the holding direction on the lower side fixed to the jaw 20 of the vise apparatus, even when the workpiece is held and processed, the vise apparatus (particularly the vice apparatus) It is possible to hold the work reliably by minimizing distortion and deformation of the base 10).

  Further, in the present embodiment, a bolt hole portion 11 for attaching a bolt 18 for fixing the vise device base 10 to the jaw 20 is formed on the inclined rear surface. In the present embodiment, five bolt hole portions 11 are formed. This is the force required to hold the workpiece, and the position of the hole formed in the jaw 20 where the vise device base 10 is installed. It can be appropriately changed in consideration of the above. In particular, the bolt hole 11 according to the present embodiment is perforated so as to extend in the vertical direction. As a result, the vise device base 10 can be securely fixed to the jaw 20, and problems such as dropping and displacement of the clamped workpiece can be prevented.

  In the vise device base 10 according to the present embodiment, the lower surface notch portion 14 for receiving the jaw 20 of the vise device is formed on the lower surface thereof. The lower surface notch portion 14 is preferably formed in a shape covering the opposing surface and the upper surface of the pair of jaws 20 formed in a rectangular parallelepiped shape. That is, the lower surface notch portion 14 is preferably formed so that the leg portion 15 extending downwards appears on the front side of the lower surface of the vise device base 10. If the lower surface notch portion 14 is formed in this way, the vise device base 10 can be present on the opposing surface side of the pair of jaws 20 that are opposed to each other, and when holding the work, the vise device base 10 The acting reaction force can be received by the leg portion 15.

  The lower surface notch portion 14 of the vise device base 10 is desirably formed in such a size that the leg portion 15 that abuts the front side of the jaw 20 (the surface side where the jaws 20 face each other) is present. The leg portion 15 is preferably formed so as to be equal to or shorter than the height of the jaw 20 to be installed. However, when installing a spacer having a predetermined thickness between the lower surface notch portion 14 and the jaw 20 on which the lower surface notch portion 14 is installed, various lengths of the leg portion 15 are adjusted. It can be installed on the jaw 20 of a size. That is, a spacer can be appropriately provided between the lower surface notch 14 and the jaw 20.

  The lower surface notch portion 14 functions to attach the vise device base 10 to the jaw 20 of the vise device. Therefore, the lower surface notch portion 14 can be formed in accordance with the size and shape of the jaw 20 on which the vise device base 10 is installed. That is, it is desirable that the vise apparatus base 10 be formed in a size and shape that accommodates the jaw 20 on which the base 10 is installed.

  In the vise apparatus base 10 according to the present embodiment formed in a lump shape, a scale 12 for positioning a workpiece is provided on the upper surface of the holding surface 17 (or the vise apparatus base 10). The scale 12 can be used as a guide for holding the work at the center in the width direction of the vise base 10 when holding the work. That is, when the work is biased in any one of the width directions of the vise device base 10, the holding force in the vise device base 10 may be biased. Therefore, in order to solve such a problem of uneven holding force, the workpiece can be set with the scale 12 as a guide.

  In particular, the base 10 for the vice apparatus according to the present embodiment is inclined on the back side as described above and has a narrow width on the top surface, so that the spindle of the processing machine and the processing blade are the jaws of the vise apparatus. No longer interferes with 20 or base. Accordingly, by installing the vise device base 10 in the vise device for the 3-axis machine, the vice device can be used in the 5-axis machine. Therefore, even if a 5-axis machine is newly introduced, it can be processed with the 5-axis machine using the vice device for the 3-axis machine that has been used so far. Can be used effectively.

  The side surface of the holding surface 17 (or the vise device base 10) is formed as a vertical surface that extends in a direction perpendicular to the table surface 22 (the vise device base 21) on which the vice device is provided, It can be formed to be inclined so as to have a tapered shape narrowed toward the surface. In particular, when a workpiece held by a vice apparatus is processed by a 5-axis processing machine, the workpiece is processed by being rotated in various directions. Therefore, in order to eliminate the restriction of the orientation of the processing machine with respect to the workpiece, the side surface of the vise apparatus base 10 can also be formed so as to be inclined toward the upper side extended from the table surface 22. Further, the side surface of the vise device base 10 can be formed such that only one of the left and right sides is inclined and the other is a vertical surface. When formed in this way, it is possible to facilitate the processing from the inclined surface side while securing the work clamping width.

  The vise device cap 10 formed as described above can be used by being fixed to the jaw 20 in the vise device as shown in FIG. FIG. 5A is an exploded vertical cross-sectional view showing an installed state on the jaw 20, and FIG. 5B is a vertical cross-sectional view in a state where a vise device base 10 is installed on the jaw 20. As shown in FIG. 5, the vise apparatus base 10 has the lower surface notch portion 14 formed on the bottom surface thereof placed on the jaw 20 of the vise apparatus on which the vise apparatus base 10 is installed, and is inclined. The vise device base 10 can be integrated with the jaw 20 of the vise device by being attached to the jaw 20 by the bolt 18 inserted through the bolt hole portion 11 formed on the back surface. Then, the workpiece to be processed by the processing machine is placed on the parallel plate 16 installed in the upper cutout portion 13, and the jaws 20 are moved toward each other to hold the side surface of the workpiece. it can. And even if the vise apparatus in which the vise apparatus base 10 is installed is processed by a 5-axis processing machine while holding the workpiece, it does not interfere with the spindle or the processing tool of the processing machine and is used for a 3-axis processing machine. Can be used on a 5-axis machine.

  FIG. 6 is a six-sided view showing a vice apparatus provided with a vise apparatus base 10 according to another embodiment, (A) rear view, (B) plan view, (C) front view, (D) right side. It is a top view, (E) bottom view, (F) FF longitudinal cross-sectional view. The vise device base 10 according to this embodiment shows an example in which the back side of the holding surface 17 is formed as a curved surface that is curved so as to be narrowed upward.

  That is, in the vise apparatus base 10 according to the present embodiment, the holding surface 17 is formed as a flat plane with respect to the table surface 22 on which the vice apparatus is provided, and the parallel plate 16 is accommodated on the upper end side thereof. A possible upper cutout portion 13 is formed, and the back side of the holding surface 17 is formed as a curved surface that is curved so as to spread downward from above. By forming the back surface as a curved surface, it is possible to further reduce the interference with the main spindle and the processing blade of the processing machine, and thus it is possible to provide a vise device base 10 that can be used in various 5-axis processing machines. . In addition, since the direction of the machining tool can be set freely, complicated machining can be performed.

Since the vise apparatus base 10 according to the present embodiment is formed with a curved surface on the back side, the force at the time of holding the work is not concentrated in one place, and the vise apparatus base 10 Can be prevented from being deformed or damaged. However, it is desirable that the thickness of the vise device base 10 is formed so as to prevent the deformation when the workpiece is held. When installed in a vice apparatus used in a general 5-axis processing machine, it is desirable that the holding surface 17 has a thickness of about 10 mm or more and a height of 15 cm or less.

  The vice apparatus base of the present invention and the vice apparatus for a 5-axis machine using the same can be used for holding a workpiece in the machine. In particular, the base for a vice apparatus according to the present invention can be used as a vise apparatus that can be used in a 5-axis processing machine by being installed in a vise apparatus for a 3-axis processing machine.
