Abstract

PURPOSE:To make light cutting including trial cutting or the like performable with a measuring instrument itself as well as to aim at promoting higher efficiency, by installing a machining device with a driving motor in a measuring head so as to cause a cutting tool to be positioned on the same axis as a stylus shaft of the measuring instrument at a time when it is drawn in. CONSTITUTION:When tracing over the whole surface of a model is over, the model form is stored in a memory 32 through data of X-, Y- and Z-axes whereby a stylus 18 is removed, then a lifting motor is rotated, and a tracer head is housed inside a Z-axis quill 12. And, a tracer saddle 8 is moved to a turnout position, attaching a cutting tool fifly to a lower end of the Z-axis quill 12 as well as attaching a working head with a motor, and styrene foam to be cut is secured onto a table 2. Next, after rotating the motor, on the basis of memory data of the memory 32 belonging to a numerical control system 31, servomotors of X-, Y- and Z-axes 3, 9 and 13 are driven by a command to be outputted out of the NC system on the condition set at an editor 33, thus cutting by 3-axis control takes place. On the basis of measuring data like this, trial cutting is made performable on the very spot.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a measuring machine capable of performing trial cutting using the measuring machine based on data of a model measured by the three-dimensional measuring machine.

Conventional technology In the past, when a model was measured by numerical control using a six-dimensional measuring machine, the data was stored in a control device, and based on this memory, trial cutting was performed using a mold processing machine using a material such as styrofoam. The cage measuring machine and the trial cutting machine are separate machines. For this reason, not only was the efficiency not improved, but also the mold processing machine used in practical use could not be used to process the mold during that time, making it uneconomical.

Purpose Therefore, this invention was made in view of the above, and the cutting tool is mounted coaxially with the tracer head in the measuring machine, so that light cutting such as trial cutting can be performed in the measuring machine itself, thereby reducing wasted time of the machine. The aim is to provide a measuring machine with a processing function that eliminates the need for such processing.

Solving means A drive motor is provided so that the measuring instrument held in the head can be retracted and stored in the head, and a cutting tool is positioned on the measuring head coaxially with the stylus axis of the measuring instrument when the measuring instrument is retracted. It is equipped with processing equipment that has

Example Embodiments of the present invention will be described below based on the drawings.

A tape/I/2 is placed on two parallel guide surfaces on the upper surface of the bed 1, and a tape/I/2 is placed on the bottom of the table which is screwed into a feed screw 4 which is rotated by an X-axis servo motor 3 via a rotation transmission mechanism. Feed is transmitted from the nut.

As for the rotation of the feed screw 4, the current X-axis position of the table is detected by a detection means 5 such as a resolver, and the data is stored in the storage device 32 in the No. device 61. Columns 6.6 are installed on both sides of the bed 10, and a tracer saddle 8 is placed on the top beam 1 of the column so as to be horizontally slidable.
Feed is transmitted from a nut on the back side of the tracer saddle 8 which is screwed into a feed screw 10 which is rotated by a Y-axis servo motor 9 via a rotation transmission mechanism. As for the rotation of the feed screw 10, the current position of the tracer saddle 8 is detected by a detection means 11 such as a resolver, and is stored in the storage device 32 in the No. device 31.

The tracer sad A/8 is provided with a Z-axis rotary 12 vertically slidable up and down, and is fed from a nut member 15 screwed onto a feed screw 14 which is rotated by a two-axis servo motor 13 via a rotation transmission mechanism. is transmitted. As for the rotation of the feed screw 14, the current position of the two-axis quill 12 is detected by a detection means 16 such as a resolver, and is stored in the storage device 32 of the No. device 31. A tracer quill 17 is supported within the biaxial quill 12 so as to be slidable in the vertical direction, and a tracer head 19 is attached to the lower end of the tracer quill 17, with a stylus 18 at its center and detachably attached thereto. . The signal outputted from the tracer head 19 is transmitted to the No. 3 device 31 through the electric wire 20. Also, tracer quill 17 is 2
The shaft quill 12 is raised and lowered by a nut member 26 that is screwed onto a lifting screw 22 that is rotated by a lifting motor 21 attached to the upper part of the shaft quill 12 via a gear mechanism, and in the lowered position, the stylus 18
takes a position that follows the model, and in the raised position, the 2-axis quill 1
2. Take the position stored inside. Tracer head 19 is 2
When the stylus 18 stored in the shaft quill 12 is removed, a high-speed spindle motor 24 is attached to the lower end of the two-shaft quill 12 and driven by electricity or air supplied from an electric wire or pipe 25. A cutting tool 26 is attached so as to be coaxial with the stylus 18. In the No. 3 device 31, shape data is stored in the storage device 32, and based on this data, machining conditions are added in the editing device 33 to control the machining of the cutting tool.

In the measuring machine thus constructed, a model to be measured is mounted on the table 2, the tracer head 19 is in the lowered position, and the stylus 18 is mounted. X axis, Y
The stylus 18 traces the model from a fixed direction by controlling the position of the two axes.

The storage device 32 stores data sequentially input by time sharing, that is, the current value in the X-axis direction when the stylus 18 makes contact with the resolver 5, the current value in the Y-axis direction from the resolver 11, and the current value in the z-axis direction from the resolver 11. The current value is input from the resolver 16 and stored in the storage device 32. When the tracing of the entire model is completed in this way, the storage device 32 contains
This means that the shape is stored with data on the axis, Y axis, and two axes. Next, to move on to trial cutting, the stylus 18 is removed, the lifting motor 21 is rotated, and the tracer head 19 is housed within the two-axis quill 12. and tracer saddle 8
Move the cutting tool 26 to the retracted position and attach the cutting tool 26 to the lower end of the two-axis quill S.
and attach the head with the motor 24.

Styrofoam to be cut is fixed on the table 2. After rotating the motor, the X-axis servo motor 3. Y-axis servo motor9. A Z-axis servo motor 13 is driven and cutting is performed under six-axis control.

Effects As detailed above, the present invention allows the tracer head of a six-dimensional measuring machine to be housed in a tile, and the cutting tool is removably attached to the tile. Trial cutting can be performed on-site and the quality of No. data can be checked. Furthermore, since an expensive mold processing machine is not used for checking the NO data, the actual operating rate of the machine is improved, making it economical.
