FIG. 3 is a side view of the stamping apparatus shown in FIG. 4 is a cross-sectional view taken along line XX of FIG. FIG. 5 is an enlarged top view of the pedestal.

  The stamping apparatus 10 according to the present embodiment includes a pedestal 11 on which the retroreflector 30 is placed, a support member 12 that supports the pedestal 11, and a stamper that is located below the center of the pedestal 11 and disposed on the support member 12. With the engraving needle 13 and the retroreflector 30 mounted on the pedestal 11, the pressing needle 14 is attached to the support member 12 so as to be movable up and down and can press the embossing needle 13 downward. . In the present embodiment, a retroreflector that reflects incident light in the incident direction is used as the retroreflector 30.

  As the retroreflector 30, for example, a spherical retro reflector can be used.

  The retroreflector 30, which is a retro reflector, is a truncated sphere and has an opening 31. Inside the opening 31, a prism 32 formed by three mirrors orthogonal to each other is arranged. The prism 32 has a triangular pyramid shape. The position of the apex of the triangular pyramid shape is the reference position C of the retroreflector 30 at the time of surveying, and coincides with the center position of the spherical retroreflector 30.

  The spherical retroreflector 30 is supported at three points by the pedestal 11, and the center position of the retroreflector 30 is located above the center position of the pedestal 11. That is, when the stamping device 10 is viewed in plan, the center of the retroreflector 30 (reference position C) coincides with the position of the center of the base 11.

  By rotating the retroreflector 30 on the pedestal 11 and changing the direction of the opening 31 of the retroreflector 30, the center position of the retroreflector 30 is matched with the center position of the pedestal 11. The direction in which the laser beam from the laser tracker is received in the opening 31 can be adjusted.

  Since the stamping device 10 can measure the distance from the retroreflector 30 using a laser tracker, the position of the reference point can be measured with an accuracy of micrometers.

  Further, as shown in FIG. 4, since the center 13a of the embossing needle 13 is located below the center of the spherical retroreflector 30, the reference point measured using the retroreflector 30 is accurately determined on the floor surface. Can be stamped on.

  Next, the configuration of the engraving apparatus 10 will be described in detail below.

  First, the pedestal 11 will be described below.

  As shown in FIGS. 4 and 5, the pedestal 11 has a circular shape in plan view, and has a recess 11 a on which the retroreflector 30 is placed. The concave portion 11a has a circular shape in plan view, and a peripheral portion thereof is an inclined tapered portion 11b. The taper portion 11 b is provided with three convex portions 11 c that support the retroreflector 30. The three convex portions 11 c are arranged at intervals of 120 degrees with respect to the center of the pedestal 11. In addition, it is good also as a structure which comprises the convex part 11c or the taper part 11b with a magnetic body, and fixes the retroreflector 30 comprised with iron. In this case, the stamping device 10 can be installed and stamped not only on a horizontal plane but also on a slope or wall.

  Since the retroreflector 30 is supported at three points by the three convex portions 11 c, the center of the spherical retroreflector 30 (reference position C) is the center of the pedestal 11 in plan view of the stamping device 10. It is accurately positioned so as to coincide with the position, and is placed on the base 11.

  Next, the support member 12 will be described below.

  The support member 12 has a cylindrical shape. The pedestal 11 is coupled to the support member 12 via the three bolts 18 a to 18 c so that the center of the pedestal 11 coincides with the center of the support member 12. Each of the three bolts 18 a to 18 c is inserted into the first lower bolt hole 12 g and the second lower bolt hole 12 h provided in the support member 12 and mated with the bolt hole 11 e provided in the base 11. The three bolts 18a to 18c are arranged at intervals of 120 degrees with respect to the center of the base 11 when the support member 12 is viewed in plan.

  The needle through hole 12a is a hole that penetrates the support member 12, and the stamping needle 13 is inserted through the needle through hole 12a. The needle through hole 12 a is located below the center of the pedestal 11, and the center 13 a of the marking needle 13 inserted into the needle through hole 12 a coincides with the center of the pedestal 11. That is, the center of the stamping needle 13 coincides with the center of the retroreflector 30 (reference position C).

  As shown in FIG. 4, the needle through hole 12 a has a bearing 12 f on a sliding surface with the punching needle 13. As the bearing 12f, for example, a ball bearing can be used. The punching needle 13 moves up and down in a state where the cylindrical side surface is supported by the bearing 12 f, thereby preventing the center position in the axial direction from deviating from the center of the pedestal 11.

  It is preferable from the viewpoint of improving workability that the stamping device 10 has a weight that does not easily move during the surveying and stamping operation of the reference point. As a material for forming the support member 12, it is preferable to use a material that gives such weight to the stamping device 10. As a material for forming the support member 12, for example, stainless steel can be used.

  A spirit level 20 is disposed on the upper surface of the support member 12. Before marking the reference point, the level of the support member 12 with respect to the floor surface is adjusted using the level 20.

  By making the support member 12 horizontal with respect to the floor surface, the reference point can be stamped in a state where the stamping needle 13 is perpendicular to the floor surface.

  The support member 12 includes three screws 15 a to 15 c that mesh with screw holes 12 b to 12 d that penetrate the support member 12. The three screws 15 a to 15 c are used for adjusting the level of the support member 12.

  Each of the three screws 15a to 15c has screw portions 16a to 16c mated with the screw holes 12b to 12d, and knob portions 17a to 17c for rotating the screw portions 16a to 16c. The screw portions 16 a to 16 c are meshed with the screw holes 12 b to 12 d, and the tips protrude from the lower surface of the support member 12. Further, the knob portions 17 a to 17 c are located on the upper surface side of the support member 12.

  In the stamping device 10, the length of the screw 15 c protruding from the lower surface of the support member 12 is fixed. As for the screw 15c, the state in which the tip portion of the screw portion 16c protrudes from the lower surface of the support member 12 is fixed, and the stamping device 10 is used. In order to adjust the level of the support member 12 during the stamping operation, the height is not adjusted using the knob portion 17c.

  On the other hand, the length of the screws 15a and 15b protruding from the lower surface of the support member 12 is adjusted by rotating the screw portions 16a and 16b using the knob portions 17a and 17b, so that the level of the support member 12 is increased. Adjusted.

  In this way, by fixing the length of the screw 15c protruding from the lower surface of the support member 12, the level of the support member 12 is adjusted from the floor surface of the stamping apparatus 10 using the two screws 15a and 15b. The height of the can be kept constant. By keeping the height of the stamping device 10 from the floor constant, the accuracy of the position where the reference point is stamped can be increased.

  In addition, since the stamping device 10 stands on the floor surface with the tips of the three screws, it can be stamped on the uneven floor surface by adjusting the level.

  Next, the pressing member 14 will be described below.

  The pressing member 14 includes a top plate portion 14 a that receives an external force, and a transmission portion 14 b that transmits the external force received by the top plate portion 14 a to the punching needle 13.

The convex portion 14h is circular, and the center position of the convex portion 14h coincides with the center position of the pedestal 11 and the center of the stamping needle 13 when the stamping device 10 is viewed in plan. As a method of applying an external force to the top plate portion 14a, the top plate portion 14a may be pushed by hand, or the convex portion 14h may be hit using a hammer or the like.

  As shown in FIG. 4, the transmission portion 14 b includes a punching needle support member 14 d that supports the punching needle 13, and a plurality of column portions 14 c that connect the top plate portion 14 a and the punching needle support member 14 d. . As shown in FIG. 2, the embossing needle support member 14d has a circular shape with a depression in plan view. In the stamping apparatus 10, the transmission part 14b has two support | pillar parts 14c. The two support columns 14c extend from both longitudinal ends of the top plate 14a toward the punching needle support member 14d so as to sandwich the base 11 and the retroreflector 30 placed on the base 11. ing.

  Thus, the two support | pillar parts 14c are located in the both sides of the retroreflector 30 mounted on the base 11, and the viewing angle of the retroreflector 30 is made wide. From this point of view, it is preferable that the thickness of the two support columns 14c is as thin as possible within the range in which the mechanical strength is maintained.

  The stamping needle support member 14 d has a fitting portion 14 e that fits with the pedestal 11. The pedestal 11 has a protruding portion 11d that protrudes from the center of the lower surface toward the cutting needle 13 side. The fitting portion 14e has a receiving portion 14f that fits with the protruding portion 11d.

  The receiving portion 14f is disposed at the center of the circular shaped needle support member 14d, and the center of the pedestal 11 is positioned at the center of the punching needle support member by guiding the protruding portion 11d of the base 11 to the receiving portion 14f. The pedestal 11 is fitted in the fitting portion 14e so as to coincide with the center of 14d.

  The pedestal 11 is supported by the support member 12 via three bolts 18a to 18c that pass through the stamping needle support member 14d, and the pressing needle support member 14d is fitted by the vertical movement of the pressing member 14. The part 14e is detachably fitted.

  The punch needle 13 is joined to the center of the lower surface of the punch needle support member 14d so that the center of the punch needle support member 14d and the center of the punch needle 13 coincide.

  Between the punch needle support member 14d and the support member 12, coil-shaped elastic members 19a to 19c around which the bolts 18a to 18c are wound are disposed so as to be elastically deformable.

  The bolts 18a to 18c include a first lower bolt hole 12g and a second lower bolt hole 12h provided in the support member 12, and a first upper bolt hole 14i and a second upper bolt hole provided in the stamping needle support member 14d. The support member 12 and the base 11 are fixed through the bolt hole 14j. The threaded portion at the tip of the bolts 18 a to 18 c fits into a bolt hole 11 e provided on the lower surface of the base 11.

  The diameter of the first lower bolt hole 12g provided in the support member 12 is larger than the diameter of the second lower bolt hole 12h by the diameter of the wire forming the coiled elastic members 19a to 19c. The diameter of the first upper bolt hole 14i provided in the embossing needle support member 14d is equal to the diameter of the wire forming the coiled elastic members 19a to 19c, rather than the diameter of the second upper bolt hole 14j. large. Accordingly, the elastic members 19a to 19c are restricted from entering the second lower bolt hole 12h and the second upper bolt hole 14j.

  The upper and lower portions of the elastic members 19a to 19c are inserted into the first upper bolt hole 14i provided in the stamping needle support member 14d and the first lower bolt hole 12g provided in the support member 12. The stamping needle support member 14d is biased upward.

  When no external force is applied to the pressing member 14 and the punching needle support member 14d is biased upward by the elastic members 19a to 19c, the base 11 is in a state of being fitted to the fitting portion 14e.

  As shown in FIG. 2, a recess 14g is provided on the outer periphery of the embossing needle support member 14d at a portion facing the knob portions 17a to 17c. The concave portion 14g is provided so that an operator can easily pinch the knob portions 17a to 17c by hand.

  Further, by providing the recess 14g on the outer periphery of the embossing needle support member 14d, the screws 15a to 15c can be disposed on the center side of the support member 12, and the outer diameter of the support member 12 can be reduced.

  When the pressing member 14 is pushed down by applying an external force equal to or greater than the urging force of the elastic members 19a to 19c to the top plate portion 14a with respect to the stamping device 10, the pressing member 14 presses the stamping needle 13 downward. The floor surface 40 is stamped.

  Since the pedestal 11 on which the retroreflector 30 is placed is supported by the support member 12 via the bolts 18a to 18c, the pedestal 11 remains stationary even if the stamping needle 13 moves. When the pressing member 14 is pushed down, the distance between the top plate portion 14a and the retroreflector 30 is shortened, but the top plate portion 14a and the retroreflector 30 are kept apart.

  When the external force of the top plate portion 14a is removed, the pressing member 14 is biased by the elastic members 19a to 19c and moves upward to return to the original state.

  FIG. 7 is a flowchart illustrating a preferred embodiment of a method of stamping a floor surface using the stamping device disclosed in this specification.

  First, in step S10, the distance and angle between the retroreflector 30 and the laser tracker are measured. While the direction of the opening 31 of the retroreflector 30 is directed toward the laser tracker, the position of the stamping apparatus 10 is moved to determine the position of the stamping apparatus 10 at a desired reference point on the floor surface.

  Next, in step S12, the level of the embossing device 10 with respect to the floor surface is adjusted using the level 20 and the screws 17a and 17b.

  Next, in step S14, an external force is applied to the pressing member 14 to push down the stamping needle 13, stamp the floor surface, and mark a reference point on the floor surface. Since the top plate portion 14a of the pressing member 14 is positioned above the punching needle 13, the direction of the external force and the direction of movement of the punching needle 13 coincide with each other, so that the punching needle 13 is driven vertically onto the floor surface. be able to. What is necessary is just to change the external force applied to the press member 14 according to the hardness of a floor surface.

  Then, when there is a reference point to be imprinted next, the processes in steps S10 to S14 described above are repeated.

  According to the above-described stamping apparatus of the present embodiment, the stamping position can be easily surveyed and stamped.

  In the present invention, the stamping apparatus according to the above-described embodiment can be appropriately changed without departing from the gist of the present invention.
