Description

  Embodiments described herein relate generally to a plate-like body manufacturing apparatus and a manufacturing method thereof.

  Conventionally, as a manufacturing apparatus for manufacturing a plate body having a curved surface shape by performing curved surface processing, the curved surface shape is roughly divided into the following two types depending on whether the curved surface shape is a large diameter curved surface shape or a small diameter curved surface shape. Manufacturing equipment is used.

  As a manufacturing apparatus for a plate-like body having a large-diameter curved surface, a manufacturing apparatus as shown in FIG. 5 is used. In the manufacturing apparatus shown in FIG. 5, the plate-like body 50 that is the workpiece is fixed on the work table 60 with the processing surface facing upward. The height position of the plate-like body 50 is adjusted by the fixed block 52.

  The work table 60 is provided with a beam 57 configured to be slidable along the longitudinal direction of the work table 60. The beam 57 is supported by a pair of columns 56, and the base end portion of the column 56 slides linearly on the work table 60. The beam 57 is provided with a machining head 54 that is slidable in a direction orthogonal to the sliding direction of the beam 57. A ball end mill 55, which is a kind of machining tool, is provided at the tip of the processing head.

By driving the beam 57 linearly, a single groove is cut by the ball end mill 55 set to a desired cutting depth on the processing surface 50a of the plate-like body 50 fixed in the work table 60. . Next, the ball end mill 55 is moved in the width direction of the plate-like body 50 to adjust the cutting depth of the ball end mill 55, and then the next single groove is cut adjacent to the previously processed single groove. In this way, the curved surface processing can be performed on the outer surface of the plate-like body 50 by successively processing the single groove while changing the cutting depth in the width direction of the plate-like body 50.
As processing apparatuses for performing such curved surface processing, for example, a three-dimensional curved surface processing apparatus and a three-dimensional curved surface processing method (see Patent Document 1) have been proposed.

  By cutting the entire processing surface 50a of the plate-like body 50 shown in FIG. 6 (a) over the entire surface with the ball end mill 55, the plate-like body is matched with the finished surface 51 as shown in FIG. 6 (b). A plurality of grooves 50b having stepped cross-sectional shapes in the width direction of 50 are formed on the processed surface 50a of the plate-like body 50. The curved surface shape to be formed on the processed surface 50a of the plate-like body 50 is a smooth curved surface shape as shown by the dotted lines in FIGS. 6 (b) and 6 (c). The curved surface shape shown is formed, and cannot be finished until the curved surface shape shown by the dotted line becomes a curved surface state like the finished surface 51.

  Therefore, the ball end mill 55 shown in FIG. 5 is repeatedly moved a desired number of times so as to reciprocate on the outer surface of the plate-like body 50 so that the height of the scallop height h which is a stepped step portion is lowered. By repeating the cutting process in this way, the stepped step portion 50c is lowered as shown in FIG. 6C. Then, by repeatedly performing the cutting process, the curved surface process is performed up to a state approximated to the finished surface 51 indicated by the dotted line.

  In FIGS. 5 and 6, the configuration in which the outer surface of the plate-like body 50 is curved is described. However, when the inner surface of the plate-like body 50 is curved, the inner surface side of the plate-like body 50 is described. Can be carried out by being arranged toward the ball end mill 55 side. Then, by moving the ball end mill 55 in a zigzag manner as described above, a concave curved surface can be processed on the inner surface of the plate-like body 50.

Moreover, as a manufacturing apparatus for producing a plate-like body having a small-diameter curved surface, a hollow cylindrical body is formed by processing the inner and outer surfaces of a round bar, and this cylindrical body is circumferentially arranged, for example, By dividing into four parts along the longitudinal direction of the cylindrical body, four plate-like bodies each having curved surfaces on the inner and outer surfaces are manufactured.
As described above, for example, a two-part bearing metal (see Patent Document 2) has been proposed as a processing apparatus that performs curved surface processing on a cylindrical body.

  As shown in FIGS. 1 and 2, the plurality of plate-like bodies 18 are placed on the rotary table 10 in an upright state, and are sandwiched from the inner and outer surfaces of each plate-like body 18 by the plurality of support members 14. Yes. As a method for sandwiching each plate-like body 18, an upper end portion and a lower end portion on the outer surface of the plate-like body 18 are supported by a pair of support members 14, respectively, and an intermediate portion on the inner surface of the plate-like body 18 is supported by the support member 14. Is supported by.

  In this way, the plate-like bodies 18 are sandwiched by the support member 14 at five points alternately in the vertical direction. As shown in FIG. 1, when viewed in plan, the plate-like body 18 is sandwiched at three points by the support member 14 in the radial direction of the turntable 10. In other words, the upper end side and the lower end side are sandwiched at three points by the support member 14 with the intermediate portion of the plate-like body 18 as a boundary. The plate-like body 18 is clamped by adjusting the holding position of the support member 14 holding the plate-like body 18 at three points, that is, the contact position where the tip of the support member 14 contacts the plate-like body 18.

Curved surface processing can also be performed on the lower end side of processing.

  In the present invention, even if the machining surface 18a is deformed during the curved surface machining, it can be easily corrected by adjusting the position of the tip of the support member 14. Since the plate-like body 18 is supported at three points by the support member 14 in plan view, it can easily cope with deformation of the machining surface 18a simply by adjusting the tip position of the support member 14. can do.

The deformation of the processed surface 18a can be easily detected even during processing by using a non-contact potentiometer or the like.
Thus, in the illustrated example, the curved surface processing can be simultaneously performed on the four plate-like bodies 18. In addition, by adjusting the feed amount of the tool post 3 and changing the type of the processing tool 5 to be used, roughing, intermediate finishing, and finishing are performed on the processing surface 18a as necessary. You can also.
