Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic copying stone processing machine that automatically processes stone into a three-dimensional shape having a concave curved surface.

In recent years, the processing of single stones has become automated, and it has become easier to process square and round shapes. In particular, since the development of automatic copy stone machining machines that use copy templates, it has become possible to automatically process complex shapes.

However, in conventional automatic copying stone machining machines, a single copying template is used in the same way as automatic copying lathes in machines, so 2') concave curved surfaces or three-dimensional shapes that combine convex and concave curved surfaces are created. could not be processed into

For example, when processing a hat for the Olympic Tower, fix the stone l on a turntable, use the cutter to process one side along the shape of the pattern plate, rotate the turntable 90 degrees, and process each side. are sequentially processed to form a square pyramid-shaped cap as shown in FIG. Next, holding a rotary cutter in hand, each side of the square pyramid shape is manually cut to form a concave curved surface 2, thereby completing the cap 3 of the Olympic Tower as shown in FIG.

Conventional automatic copy stone machining machines cannot be fully automated and have extremely poor workability.

The present invention was developed based on various researches in view of the above points, and as a result, even complex shapes such as the umbrella of the Olympic Tower, which is a combination of two concave curved surfaces, can be completely automatically removed, improving work efficiency. The present invention provides an automatic copying stone processing machine.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Reference numeral 22 denotes a guide stand formed by a cart, which rides on two rails 5.5 arranged along the Y direction, and is moved by a cylinder 23 electrically interlocked (5) with the movement of the two-way table 10. It is designed to move along the Y direction. Further, on the turntable Z side of this guide stand 22, as shown in FIG.
As shown in the figure, a vertical imitation template 25 that forms the new shape of the hat is erected.

Reference numeral 26 denotes a first copying rod that projects horizontally from the cart 4, and its tip touches the concave curved surface 2 of the horizontal copying template 24 attached to the guide stand 22.
It is designed to come into contact with.

22 is a second copying rod fixed to the side of the cutter support stand 17, and its tip is connected to the vertical copying template 2 attached to the guide stand 22.
It is adapted to slidably abut on the curved surface 28 of No. 5. In addition, 29 is a guide stand 2 for moving the cart 4 as shown in FIG.
It is a cylinder that constantly pulls to the 2nd side.

Next, the operation of the stone processing machine having the above structure will be explained.

First, stone material 1 for processing is placed on turntable 7 (6) , and fix the stone l with the center presser 9.

Next, the motor 6D of the cutter support stand 17 is driven to rotate the rotary cutter 19. In this state, a control device (not shown) drives the motor 6B, rotates the screw rod 12, and moves the two-way table IO along the Y direction on the guide pipe 11.11. At this time, in conjunction with the movement of the two-way table 10, the cylinder 23
extends and the guide stand 22 moves on the rail 5.5.

The rotary cutter 19 is attached to the cutter support stand 77U so as to be able to slide freely along the X direction on the two-way table IO, and is pressed forward by the cylinder 18, so that the rotary cutter 19 is always urged toward the stone material 1. , the second copying rod 27 connected to the cutter support stand I7 comes into contact with the vertical copying plate 250 force-branch surface 28 and moves in the Y direction without being restricted in its position in the X direction. Along with this, the guide stand 22 is also moved in the Y direction by the cylinder 23, and the horizontal copying template 24 attached thereto is also moved. On the other hand, a trolley 4 carrying stones l
is pulled toward the guide stand 22 by the cylinder 29, but the first copying rod 26 attached thereto comes into contact with the concave curved surface 2 of the horizontal copying template 24, and its movement in the X direction is restricted.

Therefore, as the rotary cutter 19 moves along the Y direction, the cart 4 moves along the concave curved surface 2 of the horizontal copy template 24 in the X direction, and the upper part of the stone l is cut. Next, the motor 6C is driven, and the screw rods 76B and 76A% 16A are rotated to lower the plug 15.15 onto the vertically arranged guide pipe 14.14, and the horizontally arranged guide pipe 11.11. The upper rotary cutter 17 descends (in the Z direction).

Therefore, by moving the two-way table 1o in the Y direction and moving the vertical copying template 25 in the X direction, the rotary cup p-z7taX
While moving in two Y directions, at the same time, the stone 1 placed on the trolley 4 moves in the X direction following the horizontal pattern plate 24, and by combining these operations, and further moving the rotary cutter 17 in the Z direction, the stone 1 is moved in the Z direction. Processing is performed sequentially from the top to the bottom, and one side of the hat is processed into a shape that combines two concave curved surfaces.

After the processing of one side is completed, each side is processed in the same way while rotating the turntable 7 by 90 degrees, thereby automatically forming the cap 3 of the Olympic tower as shown in FIG. 2.

Although the above embodiment shows a case in which one horizontal copying template 24 and one vertical copying template 25 are installed, more complex shapes can be processed by attaching multiple plates in parallel and switching them sequentially. You can also do that.

Further, in the above embodiment, a case is shown in which the horizontal copying template 24 is attached to the guide base 22 side and the first copying bar 26 is attached to the truck 4 side, but the reverse may be used.

Further, the movement of the guide stand 22 is not limited to the cylinder 23, but may be performed using a screw threaded rod, and furthermore, the movement of the guide stand 22 is not limited to the cylinder 23.
2 is not limited to a trolley-like structure, but may also be structured to run on rails.

() As explained above, according to the automatic copying stone processing machine according to the present invention, by combining two horizontal and vertical copying templates and controlling the movement of the rotary cutter and the turntable on which the stone is placed, It can completely automatically process objects with complex shapes, such as the cap of the Olympic Tower, which is a combination of two concave curved surfaces, and can greatly improve work efficiency compared to conventional processing machines. It is.
