Problems solved by technology

[0004] However, in the above-mentioned technology, a device for controlling the emission direction of laser light and an image data processing unit are separately required, so there is a problem of securing a space for installing these devices or increasing the number of components, resulting in an increase in the failure rate.

Embodiment Construction

[0022] refer to Figure 1 to Figure 3 The structure of one embodiment of the distance measuring stand of the present invention will be described.

[0023] In a machine tool capable of controlling the spindle rotation angle φ with respect to the rotation axis L around the spindle 1, as figure 1 As shown, the distance measurement bracket 5 is mounted on the main shaft 1 for use.

[0024] The distance measurement holder 5 has a mirror portion 4, and the emission angle θ of the laser light 3 emitted from the laser emission device 2 is related to the shaft rotation angle φ as a function of tanθ=f(φ). This distance measurement holder 5 includes a holder non-rotating portion 8 and a mirror portion 4 . Then, the laser emitting device 2 is mounted on the holder main body (the holder non-rotating part 8).

[0025] The control device 6 of the machine tool controls the rotation angle φ of the main shaft and gradually changes the angle φ. The control device 6 of the machine tool refers ...

Abstract

The invention provides a distance measurement holder and a machine tool having an interfering object sensing function. The distance measurement holder is attached to the main shaft of the machine tool. A laser beam emitted from a holder main body is reflected by a reflection mirror section fixed to a tapered sleeve, and reflected by a measurement target, and then received by a light receiving section provided in the holder main body. The tapered sleeve is fit into the main shaft and supported to be rotatable relative to the holder main body. The distance measurement holder is shaped such that the angle of a side surface of the reflection mirror section changes in accordance with the rotation angle of the main shaft. The distance measurement holder thus configured determines the distance between the main shaft and the measurement target to determine whether or not a jig, a workpiece, the main shaft, and a cutting tool interfere with each other in the range of a rapid positioning motion specified in an NC program.

Description

technical field [0001] The present invention relates to a machine tool having a stand for distance measurement and a disturbing object detection function. Background technique [0002] At present, in order to prevent the mutual interference of the spindle, tool, workpiece, fixture, etc. caused by the operator's operation error or judgment error during the debugging (debug) operation of the processing program, consider a method, that is, measure the workpiece, the clamp by a certain method The position and shape of the tool, by comparing the information of its position and shape with the movement path of the spindle / tool ​​to judge whether there is interference, when it is judged that interference occurs, stop the processing action to prevent interference before it happens. [0003] In order to prevent the jig, workpiece, spindle, tool, measuring device, measuring device control unit, etc. The method of limiting the movement within a range that cannot be disturbed, and consi...
