Description

  The present invention relates to a structure for fixing a device, and more particularly to an improved structure for fixing a device such as a vise to a mounting surface of a predetermined mounting base such as an acal.

  Conventionally, in order to perform predetermined processing such as cutting, polishing, drilling, etc. on a workpiece, the workpiece is sandwiched between vises called machine vise etc. and fixed to an equal (tooling block) or table. In this state, predetermined processing is being performed. In particular, machining centers have recently been required to reduce machining time and improve machining accuracy by consolidating processes, and as a result, there are increasing occasions where single-stage machining and multi-face machining are adopted, and the use of horizontal machining centers is increasing. In this situation, machine varieties are used as the most versatile jigs to cope with the increase in multi-product and small-volume production. Generally, it is attached and fixed to a mounting surface of a mounting base such as a scale (tooling block) using a plurality of mounting clamps (see Non-Patent Document 1).

  Specifically, as shown in FIGS. 11 (a) and 11 (b), with respect to the four side surfaces, which are the mounting surfaces of the rectangular block-shaped post 112 having a predetermined height, in the four-sided scale 110 serving as the mounting base. Each of the machine vises 114 is attached, and the workpiece W to be machined in each machine vise 114 is clamped and fixed, and the intended machining is performed. The four-sided scale 110 to which such a machine vise 114 is attached is fixed to a predetermined work table at a flange portion provided at a lower portion thereof.

  By the way, the machine vise 114 is attached to the four-sided scale 110, as shown in FIG. 11 (a), generally using L-shaped presser fittings 116 and fixing bolts 118, Each of them is fixed to the side surface (mounting surface) of the post 112 of the four-sided scale 110 at two locations, and therefore at four locations per machine vise 114. In such attachment, the tip of the L-shaped presser fitting 116 is engaged and set in a form in which it enters into a recess 114 a provided on the side surface of the machine vise 114, and is fixed by a fixing bolt 118. It can be fixed.

Thus, in the conventional structure of attaching the machine vise 114 to the scale 110, as shown in FIG. 11 (a), the holding metal fittings 116 and the fixing bolts 118 are arranged on both sides of the machine vise 114, respectively. Since it is necessary to fix the machine vise 114 by them, it is necessary to provide the space for arranging the presser fitting 116 and the fixing bolt 118: O on both sides of the machine vise 114. The width of the constructed mounting surface: Z ₁ had to be increased. However, when the workpiece W held by the machine vise 114 fixed to the scale 110 is subjected to predetermined machining, the workpiece W is mounted in a rotation range that can be machined without interfering with the surrounding machining machines. Since the effective range: D is uniquely determined by the size of the processing machine disposed around the workpiece, the work W that can be processed is inevitably increased when the width of the mounting surface: Z ₁ is increased. The size of the workpiece W (X ₁ × Y ₁ ) is affected, and the values of X ₁ and Y ₁ become smaller in the work W mountable size, which makes it difficult to process a large workpiece W. Yes.

  Further, since the presser fitting 116 and the fixing bolt 118 for fixing the machine vise 114 are arranged on the side surface as the mounting surface of the post 112 in the form protruding from the side surface of the machine vise 114, the workpiece W is processed. In addition to the problem of contaminating the environment around the machine vise 114 due to the generated scraps adhering to or catching on the presser fitting 116 and the fixing bolt 118, it is troublesome to remove such scraps. In particular, in the case where a plurality of machine vices 114 are installed on one mounting surface, adjacent machine vice from the viewpoint of effective use of the mounting surface. When the fixing means composed of the holding metal fittings 116 and the fixing bolts 118 arranged on the corresponding side surfaces of 114 are arranged alternately. Furnace shell caught processing waste also increases, also, like also becomes more troublesome the removal operation, those problems have become serious.

Even in such a case, there is no problem that the removal of processing waste or the like becomes extremely difficult.

  Hereinafter, in order to clarify the present invention more specifically, representative embodiments of the present invention will be described in detail with reference to the drawings.

  First, FIG. 1 schematically shows an example of a horizontal machining center that employs a fixing structure for equipment according to the present invention. Here, (a) shows the planar form of the fixing structure, and (b) shows the front form.

And as shown in (a) and (b) of FIG.
The machine vise 14 as a tool is fixed to the post 12 of the tooling block) 10 on each of the four side surfaces constituting the mounting surface in the fixing structure according to the present invention. The machine vise 14 used here has the same size as that shown in FIG. 11, but the post 12 of the four-sided scale 10 is sufficient to support the machine vise 14 as much as possible. By having a small side surface, the size is smaller than that used in FIG. The four-sided scale 10 can also be attached to a predetermined work table (not shown) at a flange portion 16 provided at the lower portion thereof.

  By the way, the machine vise 14 used in FIG. 1 has a fixed jaw 20 provided integrally with one end of the vice body 18 as shown in FIGS. The movable jaw 22 is moved forward or backward by the rotation of the spindle 24, and a predetermined workpiece (W) is sandwiched and held between the fixed jaw 20 and the movable jaw 22. It has the same structure. Then, in the lower part of both sides in the width direction of the vice main body 18 of such a machine vise 14, two insertion holes 26, 26 are respectively provided at predetermined intervals in the longitudinal direction, as is apparent from FIG. However, in the form in which the bottom surface (lower surface) of the vice body 18 is opened, it is formed to extend upward at a predetermined depth. Further, as shown in FIG. 2B, screw holes 28 reaching the fitting holes 26 are provided so as to enter the vice main body 18 from the side so as to be orthogonal to the fitting holes 26. A clamp bolt 30 can be screwed into the screw hole 28 as shown in FIG. As shown in FIG. 2 (c), on the bottom surface of the vice main body 18 of the machine vise 14, there is a key groove 29 that is located approximately at the center of each side and extends in the direction of the corresponding side. A key block is inserted into the key groove 29, as is well known, and is formed as a recess in the depth. It is positioned by being fitted into a keyway attached to the side surface.

  In addition, the clamp bolt 30 screwed into the screw hole 28 provided in the vice body 18 of the machine vise 14 has a thread formed on the outer peripheral surface thereof as shown in FIGS. 4 (a) and 4 (b). In addition, the tip portion is a conical tip portion 30a not provided with such a thread. On the other hand, a hexagonal wrench hole 30b projecting into a predetermined depth from the end face is provided on the other end side which is the base side. A predetermined hexagon wrench is fitted into the wrench hole 30b of the clamp bolt 30 and rotated, whereby the clamp bolt 30 is screwed into the screw hole 28 from the side surface of the vice body 18 and further inserted. The tip 30a can be projected into the hole 26.

  On the other hand, as shown in FIGS. 5A to 5C, the four-sided scale 10 has a shape in which rectangular block-shaped posts 12 are integrally provided on a plate-like flange 16 at a predetermined height. Each of the four side surfaces is an attachment surface to which the machine vice 14 is attached and fixed. The four side surfaces of the post 12 are provided with two key grooves 19 and 19 corresponding to the key grooves 29 provided on the bottom surface of the vice body 18 of the machine vise 14. The key block is fitted and the machine vise 14 can be positioned with respect to the post 12.

  Further, on the four side surfaces of the post 12 of the four-sided scale 10, clamping wedges 40 are positioned so as to correspond to the four insertion holes 26 provided on the bottom surface of the vice body 18 of the machine vise 14 described above. The post 12 is attached so as to protrude sideways from the side surface.

  Further, the clamping wedge 40 attached so as to protrude from the side surface of the post 12 in the four-sided scale 10 has a columnar shape as shown in FIGS. 6 (a) to 6 (e). A V-shaped groove 42 that opens in a V-shape is formed by being cut to a predetermined depth so as to extend in a direction perpendicular to the axis. The V-shaped groove 42 is formed such that the side surface on the wedge tip side provides an inclined surface 42a having a predetermined angle. In addition, a bolt hole 44 that penetrates the wedge 40 in the axial direction is provided, and a positioning pin insertion hole 46 is provided on the end surface on the contact side of the post 12.

  6 is provided with a fitting hole 48 provided at a predetermined position of the post 12, and further at the bottom of the fitting hole 48, as shown in FIG. Using the fixing screw hole 50 and the positioning hole 52, the fixing bolt hole 50 and the positioning pin 56 can be used to fix the position. That is, while the wedge 40 is fitted to the fitting hole 48 at a predetermined depth at the base, the positioning pin 56 is inserted into the positioning pin insertion hole 46 of the wedge 40, and the positioning hole on the post 12 side is further inserted. 52, the wedge 40 is positioned, while the mounting bolt 54 is inserted into the wedge 40 and further screwed into the fixing screw hole 50, so that the wedge 40 is effectively fixed to the post 12. It can be harassed. When the wedge 40 is attached to the post 12, the wedge 40 is positioned by the positioning pin 56, whereby the opening direction of the V-shaped groove 42 provided in the wedge 40 is defined. -ing The state in which the clamping wedges 40 are attached to the respective attachment surfaces (side surfaces) of the post 12 in this way is shown in FIG. 5, where the V-shaped groove 42 of each wedge 40 is provided. As shown in FIGS. 5 (a) and 5 (c), each is opened outward, so that the opening is located toward the outer surface of the machine vise 14. It has become so.

  Thus, as described above, in order to set four wedges 40 on each side of the post 12 of the four-sided scale 10 and fix the machine vice 14 thereto, for example, as shown in FIG. It will be done. That is, first, as shown in FIG. 8A, in the four insertion holes 26 provided in the machine vise 14, the clamp bolts 30 are screwed into the screw holes 28 penetrating the respective insertion holes 26. 3, after the insertion holes 26 of the machine vice 14 and the wedges 40 for clamping attached to the posts 12 are positioned correspondingly, the wedges 40 are inserted into the respective insertion holes 26 as shown in FIG. Will be. After that, as shown in FIG. 3C, the clamp bolt 30 is screwed and the tip 30a is inserted (entered) into the fitting hole 26, whereby the conical surface of the tip 30a of the clamp bolt 30 is obtained. However, the wedge 40 comes into contact with the inclined surface 42a on the wedge front end side in the V-shaped groove 42 of the wedge 40. Further, the wedge 40 is subjected to a pressing force in a direction in which the wedge 40 is pulled into the insertion hole 26 by the screwing of the clamp bolt 30 being advanced, whereby the wedge 40 can be firmly held in the insertion hole 26. As a result, the machine vice 14 can be fixed to the side surface of the post 12. In FIG. 9, the state in which the wedge 40 is securely fixed in the insertion hole 26 with such a clamp bolt 30 is shown in an enlarged manner. In order to release the fixing of the wedge 40 with respect to the insertion hole 26, the clamp bolt 30 is screwed back, and the inside of the screw hole 28 is retracted, whereby the clamp bolt 30, the inclined surface 42a of the wedge 40, and further, Is easily realized by releasing the engagement with the V-shaped groove 42, whereby the machine vise 14 can be removed from the post 12.

Thus, as shown in FIG. 1, the machine vise 14 can be effectively fixed to the four side surfaces (mounting surfaces) of the post 12 in the four-sided scale 10, respectively. Unlike the conventional fixing structure, between the bottom surface of the machine vise 14 and the side surface of the post 12, the coupling hole 26, the clamping wedge 40, and the clamp bolt 30 can be securely connected and fixed. Since the side surface of the machine vice 14 is not used for clamping, the side surface to be the mounting surface of the post 12 can be made as small as possible as required for mounting the vice 14. and become the thereby, such mounting space as shown in Figure 11: since there is no need to provide the O, the width of the post 12 is possible to reduce the Z ₂ It is become Noh.

Thus, the width of the post 12: Z ₂ can be reduced, so that the size of the workpiece W that can be clamped by the machine vise 14, that is, (X ₂ × Y ₂ ) is the size of the surrounding processing machine It is possible to effectively increase the effective installation range D determined by: Incidentally, when the work size that can be mounted in the mounting structure as disclosed in FIG. 1 is compared with that in the conventional mounting mechanism, when the width dimension Y of the work W is the same, the X dimension is the post of the scale 12. The surface X / 2 can be taken larger.

  Further, in the fixing structure of the machine vise 14 as shown in FIG. 1, since there are no holding metal fittings 116 or fixing bolts 118 as in the conventional mechanism of FIG. The problem of adhering and staying there and making it difficult to remove can be advantageously eliminated. In particular, even when a plurality of machine vices 14 are arranged and fixed on a predetermined mounting surface, as shown in FIG. 10, there is a conventional holding member in the arrangement gap of the machine vise 14 arranged on the mounting surface 60. Since it is not necessary to arrange metal fittings and fixing bolts, it is very easy to remove processing waste around the machine vice 14.

  The exemplary embodiments of the present invention have been described in detail above, but these are merely examples, and the present invention is not limited in any way by specific descriptions according to such embodiments. It should be understood that this is not to be interpreted.

  For example, in the embodiment described above, a form in which a machine vise is fixed to each of the four sides of the four-sided scale as the mounting base is shown. Even in the case of two-sided or one-sided, the present invention can be applied in the same manner. Further, in addition to the scale, various known mounts are adopted, for example, a flat surface. There is no problem even if it is a mounting table or the like. These mounting bases are provided with one or a plurality of mounting surfaces.

  In addition, even in a machine fixed to the mounting surface of such a mounting base, in addition to the illustrated machine vise, various types of vices and clamps, as well as various known tools, instruments, tools, machines, etc. It is possible to target.

  Further, the clamp wedge 40 is provided with a V-shaped groove 42 as an engagement groove according to the present invention. The side surface of the wedge 40 at the tip side of the engagement groove is an inclined surface (42a). As long as it is, it is also possible to employ engagement grooves of other shapes other than the V-shape.

  Furthermore, in the above-described embodiment, in order to fix the machine vise 14 to the side surface of the post 12, fixing using the fitting holes 26, the clamping wedges 40, and the clamp bolts 30 is performed on both sides of the machine vise 14. The mechanism is arranged in two places (four places in total), but the number of arrangements is appropriately selected depending on the size and size of the equipment to be fixed such as a machine vise, For example, it is possible to provide two places as a whole, or to provide three places or five or more places.
