Providing a highly practical support device that can support the object to be supported stably even when a load is applied after processing, etc., and can save material and reduce processing time. To do.

  The gist of the present invention will be described with reference to the accompanying drawings.

  It has a pair of fixed support body 2 and a pair of movable support bodies 3 which are installed on the installation surface 1 and which receive the support object 5 and whose opposing directions intersect each other, and the height positions of the pair of fixed support bodies 2 are substantially the same. The inclination of the support object 5 received by the fixed support 2 or the movable support 3 with respect to the installation surface 1 is adjusted by moving the pair of movable supports 3 up and down while being fixed at a height. Then, the support device supports the support object 5 at four points, and the movable support 3 is lifted from a reference position lower than the fixed support 2, and the support object received by the fixed support 2. Measurements for measuring the ascending distance from the reference position of the movable support 3 until the object 5 is pressed against the object 5 or the height position of the movable support 3 in the state of being pressed and contacted with the support object 5, respectively. Mechanism and this A difference in height or height difference of each movable support 3 is calculated from the ascent distance or height position of each movable support 3 measured by the measuring mechanism, and the difference in height or difference in height is calculated. An inclination automatic adjustment mechanism that supports the support object 5 at four points by raising the movable support 3 on the low position side by a half of the difference and lowering the movable support 3 on the high position side; The present invention relates to a support device provided.

  Further, the opposing direction of the pair of fixed support bodies 2 and the opposing direction of the pair of movable support bodies 3 so that the pair of movable support bodies 3 can be moved up and down at the left and right side positions of the fixed support body 2. 2. The support device according to claim 1, wherein an angle is set.

  Further, the measuring mechanism is configured to measure the amount of ascending movement of the movable support 3 from the reference position until the movable support 3 is pressed against the support object 5 when the movable support 3 is raised. It concerns on the support apparatus of any one of Claim 1, 2 characterized by these.

  The support device according to claim 1, wherein the measurement mechanism is provided on the movable support body 3.

  Since the present invention is configured as described above, it is possible to support the support object at four points in a state in which the support object and each support are brought into close contact with each other and the load is evenly distributed and the cutting allowance is minimized. Even if a load is applied by performing processing or the like, the support object can be stably supported, and the support device can be excellent in practicality, which can eliminate waste of materials and reduce processing time.

  Further, when the measuring mechanism is provided on the movable support, it is not necessary to provide an external sensor separately from the movable support, and the highly accurate automatic tilt adjustment operation can be performed more easily and quickly.

  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  In a state where the movable support 3 is set at a reference position slightly lower than the pair of fixed supports 2 fixed at substantially the same height position, for example, a rectangular shape having a deformed portion is warped by a height L. When the support object 5 which is the plate material is placed, the support object 5 is inclined not only by each fixed support body 2 but also by any one of the movable support bodies 3 (see FIG. 2). FIG. 12 (a)). In this state, when each movable support 3 is raised until each movable support 3 presses against (supports) the support object 5, the support object 5 has a pair of fixed support 2, a pair of movable support 3, and the like. It will be in the state received by 4 points | pieces (FIG.12 (b)).

  At this time, the rising distance (or the height position in the state of pressing contact) of the movable support 3 from the reference position to the pressing object 5 is measured, the difference between the two is calculated, and 1 / of this difference is calculated. By raising the movable support 3 on the lower position side by 2 and lowering the movable support 3 on the higher position side, the inclination is adjusted so as to minimize the cutting allowance (FIG. 12C). ). The adjustment of the inclination is repeated until each movable support 3 has the same height.

  For example, conventionally, when a flat plate whose upper and lower surfaces are parallel from a workpiece 5 ′ having a deformed portion such as warping (a square shape with a side of 300 mm), as shown in FIG. A horizontal surface is cut and formed on the upper surface side by placing it on a surface plate 1 'set on a surface or the like so that the deformed projecting portion is on the upper side (FIG. 11 (a)). Generally, it is prepared by placing on the surface plate 1 'so as to be on the lower side, and cutting and forming a horizontal plane so as to eliminate the deformed portion on the opposite surface (FIG. 11 (b)). For this reason, it is necessary to cut the height L of the deformed portion almost exactly on the top and bottom surfaces, which increases the amount of processing, wastes material, and increases the processing time.

  In this regard, when the horizontal plane is cut and formed on the upper and lower surfaces in the same manner as in FIG. 11 with the inclination adjusted by the present invention and supported at four points, it is illustrated in FIGS. 13 (a) and 13 (b). In this way, the cutting allowance is reduced, it is possible to reduce the waste of the material, and the processing time can be shortened (not only to form a flat plate, but also when performing other processing, Cutting cost is reduced.) That is, the installation surface 1 is designed so that the load is balanced as much as possible between the pair of fixed supports 2 so that the cutting allowance is reduced as much as possible as a whole considering the deformed portion of the support object 5. In order to adjust the inclination of the movable object 3, it is possible to process so as to leave the central portion of the support object 5 as much as possible. As illustrated in FIGS. When the movable support 3 is controlled to move up and down by half (10 mm) of L (20 mm) and the inclination is corrected, the degree of protrusion of the cut portion is lower than when the correction is not made (20 mm → 14). Therefore, it is possible to reduce the cutting allowance, reduce waste of materials, and perform processing in a shorter time.

  That is, the tilt adjustment of the support object 5 is automatically performed so that the difference in distance from the reference installation surface 1 (for example, a surface plate) to the four vertices of the fixed support 2 and the movable support 3 is minimized. Thus, the cutting allowance can be minimized.

  Further, when adjusting the degree of inclination as described above, the load applied to the movable support 3 is adjusted, and the respective supports 2 and 3 are brought into close contact with the support object 5 without gaps, so that the respective supports 2 and 3 are evenly distributed. The load can be distributed.

  That is, one movable support body 3 that received the support object 5 in a state where the support object 5 was received at 3 points before receiving at the 4 points was not received the support object 5 at the lower position side. The other movable support body 3 is on the high position side, and a larger load is applied by raising one of the low position side movable support bodies 3 and lowering the other movable support body 3 on the high position side. The load of one movable support 3 on the low position side is moved to the other movable support 3 on the high position side, and the load is evenly applied to each movable support 3 with the pair of fixed supports 2 as a boundary. It is possible to support four points stably.

  Further, by using the pair of movable supports 3, the inclination of the support object 5 can be increased by moving the movable supports 3 up and down on the left and right sides of the fixed support 2 with the pair of fixed supports 2 as fulcrums. Therefore, even when a heavy object is supported, the load distribution operation can be favorably performed by the movable support 3 (movable jack) having a small thrust.

  Further, for example, when the measurement mechanism is configured to measure the amount of ascending movement of the movable support 3 from the reference position until it presses and contacts the support object 5, and this is provided on the movable support 3, It is not necessary to provide a separate sensor for measurement in addition to the support, and the arrangement and setting are simpler, extremely easy to handle, and excellent in practicality.

  Therefore, for example, when the fixed support body 2 and the movable support body 3 are arranged on a work table or a measurement surface plate of a machine tool and the support object 5 is supported at four points, it is processed by an appropriate processing apparatus. In addition to maintaining the support state (inclined state) of the support object 5 at a constant level, it is possible to perform the processing satisfactorily, as well as to reduce the cutting allowance so that the material is not wasted and the processing can be performed in a shorter time. It becomes possible.

Thus, the ascending distance from the reference position of the movable support 3 until it is brought into press contact with the support object 5 received by the fixed support 2, or the state in which the support object 5 is in press contact with the support object 5, respectively. Height of movable support 3 A measuring mechanism that measures each position, and a difference in height or height difference of each movable support 3 is calculated from the ascent distance or height position of each movable support 3 measured by this measuring mechanism. The movable object 3 on the lower position side is raised by a half of the difference in the ascending distance or the height difference, and the movable object 3 on the higher position side is lowered, so that the support object 5 is moved to four points.
