Description

DETAILED DESCRIPTION OF THE INVENTION [Invention No. 1] Field of the Invention The present invention relates to an automatic tool diameter measuring device that is programmable.

[Background of the invention]

Traditionally, tool diameter measurements have been done manually using measuring tools such as micrometers. The total diameter was determined by measuring the distance from the center of the tool to the outside diameter of the tool using a die gill gauge and a block gauge.

However, the +tiJ method has poor accuracy due to the manual intervention.
Kana often has the disadvantage that there is little flexibility in changing the tool diameter or measurement position.

[Purpose of the invention]

The purpose of this investigation is 4J! , several pieces can be installed in any position! To provide a 1F measuring device capable of measuring the diameter df side of a tool at different positions and the position #I side of an arbitrary position of the tool.

[Summary of the invention]

The feature of the present invention is that it is possible to position the tool to be measured at any position by using a numerical system @1 block diagram. For this reason, if the length/length is brought into contact with an arbitrary position of the tool to be measured, 7 can be obtained. In synchronization with side adjustment No. 16, which is sent when the tattese/su g1' comes into contact with the secondary tool, the current position of the tool at the time of contact is It? c-Input into the value control device and calculate 11 of the tool diameter! ! All right now.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings.

In FIGS. 1 and 2, an X 1+lb moving slide 21 and a Y control moving slide 22 are mounted on the four-way machine head 20, which move while directly firing each other. Touche/v30

11 moves together with the slide 21. The tool mounting arbor 60 is circumferentially surrounded by the tool arbor identification device W, 60 to which the tool 50 is attached, and is fixed to a safeter push stand 611 that is parallel to the Y axis. Tool 5
The positional relationship between 0 and Tatsutese/su 30 is fixed so that the center lines coincide with each other so as to overlap the second line. Therefore, the distance in the X-axis direction between the contact position between the touch sensor 3o and the tool 5° and the center of the tool 50 matches the radius of the tool 500. The numerical control device 1゜ includes a program 1゜information processor 11 that decodes the numerical control program and creates NC commands, and an X-axis servo mechanism 40 that generates movement pulses corresponding to the NC commands.
a pulse distribution circuit 13 that drives the The current position of the machine is recorded in synchronization with the number 1. It consists of a current position importing device 14 that imports data into the σ device 12, and a tool diameter data display device 15 that displays the result of 61 calculations of the tool diameter.

The program information processing device 11 decodes the toolability measurement program, retrieves a safe program take from the storage device 12 into a tourogram, performs calculations, creates a movement command, and transfers it to the pulse distribution circuit 13. Pulse distribution circuit 13tri movement command Movement pulse 'k' in response to reading command X-axis movement light 21 fully driven X!l!l
It is sent to the Y-axis servo controller 41 that drives the 11 servo mechanism 40 and the Y-axis moving slide 22.

XI! so that the touch sensor 30 and the tool 50 are in contact with each other.
ll1I move slide 21 and YIl! The lil moving slide 22 is moved by the Florida City IJ fdll. The moment the touch sensor 30 and the tool 50 come into contact, a touch signal is generated from the touch sensor 30. The touch signal is transferred to the capture device 14 after the light is installed in the numerical value 11i111 wholesale device 10, and the current position capture device 14i1X is transferred to the moving slide 21 in synchronization with the touch signal.
The current position of the Y-axis movement field 22 is taken into the il reference device 12. The program information processing device 11 is

Move in qi+ direction. Point 2 is a point near the tool 50 where the measurement point and the same position of the yield force coincide. Next, the touch sensor 30 moves in the X@ direction from point 2 to point 4 corresponding to step 60 in FIG. However, at point 4, touch sensor 30 and tool 50 come into contact, so a touch signal is transmitted to step 7 (corresponding to step 1, 80 in FIG. 3) at point 4.
After the current position data is taken in, the tool diameter is measured in step 90 of FIG. Touch sensor 30 then moves to point 2 in response to step 100 in FIG. Thereafter, steps 40 to 1 in FIG.

1) Detection of the contact position between the tool 50 and the center is carried out by means of a contact point, but if the reliability that can be achieved when detecting the center can be accurately determined, a light reflection type or a magnetic sensitive type may be used. An alternative method of using a non-contact type top/stool is considered.

Furthermore, by applying the tool mounting arbor fixing device 60 to the work head of a tool grinding machine, the grinding results can be quickly and accurately measured on the machine, and the measurement results can be used immediately in the next operation.
