Description

本発明は三次元測定機に関する。   The present invention relates to a coordinate measuring machine.

従来、被測定物の外形などを測定するためのプローブと、測定者の手で握られる把持部を有し、複数の可動アームからなってプローブを移動させる移動機構とを備えた手動式の三次元測定機が知られている（例えば、特許文献１参照）。
被測定物の外形などを測定するときには、測定者は、把持部を手で握ってプローブを手動で動かし、プローブを被測定物の外形のうちの所定の測定箇所に接触させる。 Conventionally, a manual tertiary that has a probe for measuring the outer shape of the object to be measured and a moving mechanism that has a gripping part that can be grasped by a measurer's hand and moves the probe by a plurality of movable arms. An original measuring machine is known (see, for example, Patent Document 1).
When measuring the outer shape or the like of the object to be measured, the measurer manually moves the probe by holding the grip portion with his / her hand and brings the probe into contact with a predetermined measurement position in the outer shape of the object to be measured.

測定箇所の測定データを取得するときには、プローブを各々の測定箇所に接触させるたびに、把持部などに設けられた測定データ入力用スイッチを手で押圧操作する。また、この押圧操作により複数の可動アームの角度なども同時に取得され、この可動アームの角度などに基づいて、各々の測定箇所の測定データが三次元座標として取得される。   When acquiring the measurement data of the measurement location, each time the probe is brought into contact with each measurement location, the measurement data input switch provided on the gripping part or the like is manually pressed. In addition, the angle of the plurality of movable arms is also acquired at the same time by this pressing operation, and measurement data of each measurement location is acquired as a three-dimensional coordinate based on the angle of the movable arm.

特開２００５−１４７６７３号公報JP 2005-147673 A

しかし、特許文献１に記載のような従来の手動式の三次元測定機では、例えば、被測定物の外形が曲面形状のような場合には、押圧操作の際の外力によって、プローブが測定箇所からずれ、プローブによって測定される測定データに誤差が生じて適切に測定データを取得できず、測定箇所の三次元座標を適切に測定できない。   However, in the conventional manual three-dimensional measuring machine as described in Patent Document 1, for example, when the outer shape of the object to be measured is a curved surface, the probe is moved to the measurement location by an external force during the pressing operation. Therefore, the measurement data measured by the probe has an error and the measurement data cannot be acquired properly, and the three-dimensional coordinates of the measurement location cannot be measured appropriately.

一方、このような場合に、押圧操作を行ってもプローブが測定箇所からずれないようにすべく、手に力を入れるなどして測定する方法が考えられる。しかし、そのような測定方法では、三次元測定機の操作性が悪く、測定に時間がかかってしまう。   On the other hand, in such a case, a method of measuring by putting a force on the hand is conceivable so that the probe does not deviate from the measurement location even if a pressing operation is performed. However, with such a measurement method, the operability of the coordinate measuring machine is poor, and measurement takes time.

本発明の目的は、測定箇所の測定データを適切に取得できて操作性も良い手動式の三次元測定機を提供することである。   An object of the present invention is to provide a manual three-dimensional measuring machine that can appropriately acquire measurement data at a measurement location and has good operability.

本発明の三次元測定機は、被測定物を測定するためのプローブと、前記プローブを移動させる移動機構と、前記移動機構を制御する制御手段とを備え、前記プローブが前記移動機構を介して手動で移動される三次元測定機であって、外部からの入力信号を前記プローブ及び前記移動機構に外力を作用させずに入力させる信号入力手段を有し、前記制御手段は、前記入力信号に基づいて前記測定データを取得する動機となるトリガ信号を生成する信号処理部と、前記トリガ信号を前記信号処理部から受け取ることによって前記測定データを取得するデータ取得部とを備えることを特徴とする。   The three-dimensional measuring machine of the present invention includes a probe for measuring an object to be measured, a moving mechanism for moving the probe, and a control means for controlling the moving mechanism, and the probe passes through the moving mechanism. A coordinate measuring machine that is manually moved, and has signal input means for inputting an external input signal to the probe and the moving mechanism without applying an external force, and the control means receives the input signal. A signal processing unit that generates a trigger signal that serves as a motivation for acquiring the measurement data based on the data, and a data acquisition unit that acquires the measurement data by receiving the trigger signal from the signal processing unit. .

このような構成によれば、外部からの入力信号がプローブ及び移動機構に外力を作用させずに入力される。このため、測定箇所の測定データを取得するときに外力がプローブや移動機構に作用せず、プローブが測定箇所からずれずに、測定データを適切に取得できる。
また、プローブの位置ずれなどを意識して測定をすることがなくなり、測定を容易に行うことができ、三次元測定機の操作性を向上させることができる。 According to such a configuration, an input signal from the outside is input without applying an external force to the probe and the moving mechanism. For this reason, when acquiring the measurement data of a measurement location, external force does not act on a probe or a movement mechanism, and a measurement data can be acquired appropriately, without a probe shifting from a measurement location.
In addition, the measurement is not performed in consideration of the positional deviation of the probe, the measurement can be easily performed, and the operability of the coordinate measuring machine can be improved.

本発明の三次元測定機において、前記信号入力手段は、前記入力信号として音声を入力させることが好ましい。
このような構成によれば、信号入力手段に入力信号として音声が入力され、この音声に基づいたトリガ信号を動機として、測定データがデータ取得部によって取得される。このため、１人で測定している場合でも、測定者自身が音声を発することによって測定箇所の測定データを容易に取得できる。 In the three-dimensional measuring machine according to the present invention, it is preferable that the signal input means inputs voice as the input signal.
According to such a configuration, voice is input as an input signal to the signal input means, and measurement data is acquired by the data acquisition unit using a trigger signal based on the voice as a motive. For this reason, even when the measurement is performed by one person, the measurement data of the measurement point can be easily obtained by the measurement person himself / herself making a sound.

本発明の三次元測定機において、前記信号入力手段は、前記移動機構に形成されて前記プローブを移動させる際に手で把持される把持部に設けられることが好ましい。
このような構成によれば、手の近くにある信号入力部に音声を入力できるため、測定者が大きな音声を発しなくても、音声を容易に入力することができる。 In the three-dimensional measuring machine according to the present invention, it is preferable that the signal input means is provided in a grip portion that is formed in the moving mechanism and is gripped by a hand when the probe is moved.
According to such a configuration, since the voice can be input to the signal input unit near the hand, the voice can be easily input even if the measurer does not make a loud voice.

または、本発明の三次元測定機において、前記信号入力手段は前記制御手段に設けられることが好ましい。
このような構成によれば、制御手段として信号入力手段を備えたものを利用できるため、三次元測定機に新たな別の構成機器を追加しなくてすみ、三次元測定機の製造コストを低減できる。 Or in the coordinate measuring machine of this invention, it is preferable that the said signal input means is provided in the said control means.
According to such a configuration, it is possible to use a signal input means as a control means, so there is no need to add another new component device to the coordinate measuring machine, and the manufacturing cost of the coordinate measuring machine is reduced. it can.

本発明の三次元測定機において、前記信号処理部は、前記トリガ信号とは異なる信号であって、前記制御手段を動作させる操作信号を生成することが好ましい。
このような構成によれば、操作信号に基づいて制御手段を動作させるため、測定者が、測定中に手などで制御手段を操作する必要がなくなり、測定者が制御手段から離れたところで測定している場合などであっても、制御手段を動作させることができる。 In the coordinate measuring machine of the present invention, it is preferable that the signal processing unit generates an operation signal that is different from the trigger signal and that operates the control means.
According to such a configuration, since the control unit is operated based on the operation signal, it is not necessary for the measurer to operate the control unit by hand during the measurement, and the measurement is performed when the measurer is away from the control unit. Even in such a case, the control means can be operated.

In each embodiment, the same reference numerals are given to the same components, and descriptions thereof are omitted or simplified.

＜第１実施形態＞
図１に示すように、三次元測定機１は、被測定物Ｗを測定するためのプローブ２と、プローブ２を移動させる移動機構としての三次元測定機本体３とを備えており、プローブ２が三次元測定機本体３を介して手動で移動されて被測定物Ｗの形状や寸法などを測定するものである。 <First Embodiment>

A grip portion 52 is provided at the base 51 of the support arm 5, and a support portion 53 that supports the probe 2 is provided at the tip of the support arm 5.
The grip 52 is provided with a microphone 6 as signal input means. The microphone 6 receives a sound as an input signal that is emitted to acquire measurement data at a measurement location.

また、三次元測定機１は、図２に示すように、三次元測定機本体３を制御する制御手段１０を備えている。制御手段１０は、信号処理部としての音声処理部１０１と、データ取得部１０２と、データ処理部１０３と、表示部１０４とを備えている。   Moreover, the coordinate measuring machine 1 is provided with the control means 10 which controls the coordinate measuring machine main body 3 as shown in FIG. The control means 10 includes an audio processing unit 101 as a signal processing unit, a data acquisition unit 102, a data processing unit 103, and a display unit 104.

音声処理部１０１は、音声に基づく音声信号をマイク６から受け取り、その音声信号が信号処理されて音声によって意図されていることが判別されたときに、その音声信号に基づいて測定箇所の測定データ取得の動機となるトリガ信号を生成し、データ取得部１０２にそのトリガ信号を送出する。
また、音声処理部１０１は、その音声信号に基づいて、トリガ信号とは異なる信号である操作信号を生成する。 The voice processing unit 101 receives a voice signal based on the voice from the microphone 6, and when the voice signal is subjected to signal processing and is determined to be intended by voice, the measurement data of the measurement location is measured based on the voice signal. A trigger signal that is a motivation for acquisition is generated, and the trigger signal is sent to the data acquisition unit 102.
In addition, the sound processing unit 101 generates an operation signal that is a signal different from the trigger signal based on the sound signal.

データ取得部１０２は、音声処理部１０１からのトリガ信号を受け取り、そのことを動機として測定箇所の測定データを取得する。加えて、データ取得部１０２は、可動アーム４１，４２，４３の角度データなども取得する。そして、データ取得部１０２は、その測定データや角度データをデータ処理部１０３に送出する。   The data acquisition unit 102 receives the trigger signal from the sound processing unit 101, and acquires measurement data of the measurement location using this as a motive. In addition, the data acquisition unit 102 acquires angle data of the movable arms 41, 42, and 43. Then, the data acquisition unit 102 sends the measurement data and angle data to the data processing unit 103.

データ処理部１０３は、測定箇所の測定データや可動アーム４１，４２，４３の角度データをデータ取得部１０２から受け取り、また、音声処理部１０１から操作信号も受け取り、それらのデータと操作信号に基づいて演算処理などによって、測定箇所の三次元座標データや、被測定物Ｗの外形形状や寸法などを算出する。そして、その算出結果を表示部１０４に送出する。
表示部１０４では、データ処理部１０３での算出結果や、それに基づいて可視化された被測定物Ｗの外形などが表示される。 The data processing unit 103 receives measurement data of measurement points and angle data of the movable arms 41, 42, and 43 from the data acquisition unit 102, and also receives operation signals from the audio processing unit 101, and based on those data and operation signals. Then, the three-dimensional coordinate data of the measurement location, the outer shape and dimensions of the object to be measured W, etc. are calculated by arithmetic processing or the like. Then, the calculation result is sent to the display unit 104.
The display unit 104 displays the calculation result of the data processing unit 103, the outer shape of the workpiece W visualized based on the calculation result, and the like.

次に、図３に基づいて、以上のような三次元測定機１によって、被測定物Ｗの外形などを測定する際の動作フローを説明する。以下では、各動作ステップをＳ１，Ｓ２，・・・で示す。   Next, based on FIG. 3, an operation flow when measuring the outer shape and the like of the workpiece W with the coordinate measuring machine 1 as described above will be described. In the following, each operation step is denoted by S1, S2,.

まず、三次元測定機本体３が手動によって動かされ、測定子２１が被測定物Ｗの表面の、例えば図１に示す測定箇所に当接される。そして、可動アーム４２をロックする旨の入力信号としての操作指令Ｔ１がマイク６から入力されて可動アーム４２がロックされる。次に、測定を開始する旨の入力信号としての操作指令Ｔ２がマイク６から入力されて測定が開始される。   First, the coordinate measuring machine main body 3 is moved manually, and the measuring element 21 is brought into contact with the measurement location shown in FIG. Then, an operation command T1 as an input signal for locking the movable arm 42 is input from the microphone 6 and the movable arm 42 is locked. Next, an operation command T2 as an input signal for starting measurement is input from the microphone 6 and measurement is started.

測定が開始されると、測定箇所での測定データを取得する旨の入力信号としてのトリガ指令Ｔ３がマイク６から入力される。
制御手段１０は、Ｓ１において、トリガ指令Ｔ３が入力されたか否かを信号処理によって判断する。トリガ指令Ｔ３は入力されていないと判断した場合には、制御手段１０はトリガ指令Ｔ３の入力を待つ。 When measurement is started, a trigger command T3 is input from the microphone 6 as an input signal for obtaining measurement data at a measurement location.
In S1, the control means 10 determines whether or not the trigger command T3 is input by signal processing. If it is determined that the trigger command T3 has not been input, the control means 10 waits for the input of the trigger command T3.

一方、制御手段１０が、トリガ指令Ｔ３が入力されたと判断した場合にはＳ２に移行し、音声処理部１０１が、トリガ指令Ｔ３の音声信号に基づいてトリガ信号を生成する。そのトリガ信号は音声処理部１０１からデータ取得部１０２に送出される。
その後、Ｓ３において、データ取得部１０２は、トリガ信号を音声処理部１０１から受け取ることによって測定箇所の測定データを取得する。加えて、データ取得部１０２は、可動アーム４１，４２，４３の角度データなども取得する。 On the other hand, when the control means 10 determines that the trigger command T3 has been input, the process proceeds to S2, and the sound processing unit 101 generates a trigger signal based on the sound signal of the trigger command T3. The trigger signal is sent from the audio processing unit 101 to the data acquisition unit 102.
Thereafter, in S <b> 3, the data acquisition unit 102 receives the trigger signal from the sound processing unit 101 to acquire measurement data of the measurement location. In addition, the data acquisition unit 102 acquires angle data of the movable arms 41, 42, and 43.

そして、Ｓ４において、データ処理部１０３に、測定箇所の三次元座標データや、被測定物Ｗの外形形状や寸法などを算出させ、その算出が終了したら算出結果を表示部１０４に表示させて測定を終了する旨の入力信号としての操作指令Ｔ４がマイク６から入力されたか否かが制御手段１０によって判断される。
制御手段１０が、操作指令Ｔ４は入力されていないと判断した場合にはＳ１に戻り、再度Ｓ１〜Ｓ３が実行されて測定が継続され、データ取得部１０２が複数の測定箇所での測定データを取得する。 In S4, the data processing unit 103 is caused to calculate the three-dimensional coordinate data of the measurement location, the outer shape and dimensions of the workpiece W, and when the calculation is completed, the calculation result is displayed on the display unit 104 to perform measurement. The control means 10 determines whether or not an operation command T4 as an input signal for ending is input from the microphone 6.
When the control means 10 determines that the operation command T4 is not input, the process returns to S1, S1 to S3 are executed again, the measurement is continued, and the data acquisition unit 102 obtains measurement data at a plurality of measurement points. get.

一方、制御手段１０が、操作指令Ｔ４は入力されたと判断した場合にはＳ５に移行し、
データ処理部１０３が、複数の測定データや可動アーム４１，４２，４３の角度データなどに基づいて測定箇所の三次元座標データを求め、その三次元座標データに基づいて、被測定物Ｗの外形形状や外形寸法などを算出する。そして、Ｓ６に移行して、この算出結果が表示部１０４に送られて表示部１０４で表示される。その後、測定が終了される。 On the other hand, when the control means 10 determines that the operation command T4 has been input, the process proceeds to S5,
The data processing unit 103 obtains three-dimensional coordinate data of the measurement location based on a plurality of measurement data, angle data of the movable arms 41, 42, 43, and the like, and based on the three-dimensional coordinate data, the outer shape of the object W to be measured Calculate the shape and external dimensions. Then, the process proceeds to S <b> 6 and the calculation result is sent to the display unit 104 and displayed on the display unit 104. Thereafter, the measurement is terminated.

本実施形態の三次元測定機１では、以下の効果がある。
トリガ指令Ｔ３が、プローブ２及び三次元測定機本体３に外力を作用させずにマイク６に入力される。このため、測定箇所の測定データを取得するときに、外力がプローブ２や三次元測定機本体３に作用しないので、プローブ２が測定箇所からずれずに、測定データを適切に取得できる。また、プローブ２の位置ずれなどを意識して測定をすることがなくなり、測定を容易に行うことができ、三次元測定機１の操作性を向上させることができる。 The coordinate measuring machine 1 of the present embodiment has the following effects.
The trigger command T3 is input to the microphone 6 without applying an external force to the probe 2 and the coordinate measuring machine main body 3. For this reason, since external force does not act on the probe 2 and the coordinate measuring machine main body 3 when acquiring the measurement data of the measurement location, the measurement data can be appropriately acquired without the probe 2 being displaced from the measurement location. In addition, the measurement is not performed in consideration of the positional deviation of the probe 2, and the measurement can be easily performed, and the operability of the coordinate measuring machine 1 can be improved.

また、音声によるトリガ指令Ｔ３がマイク６に入力され、トリガ指令Ｔ３に基づいたトリガ信号を動機として、測定箇所の測定データがデータ取得部１０２によって取得される。このため、１人で測定している場合でも、測定者自身が音声を発することによって測定箇所の測定データを容易に取得できる。   In addition, a voice trigger command T3 is input to the microphone 6, and the data acquisition unit 102 acquires measurement data of a measurement location with a trigger signal based on the trigger command T3 as a motive. For this reason, even when the measurement is performed by one person, the measurement data of the measurement point can be easily obtained by the measurement person himself / herself making a sound.

さらに、手で握られる把持部５２にマイク６が設けられているため、手の近くにあるマイク６にトリガ指令Ｔ３を入力でき、大きな音声を発しなくても、トリガ指令Ｔ３を容易にマイク６に入力することができる。
また、音声処理部１０１は操作信号も生成し、その操作信号に基づいて、データ処理部１０３が動作されたり、制御手段１０によって可動アーム４２がロックされる。このため、測定者が、測定中に手などで制御手段１０を操作して、データ処理部１０３や可動アーム４２の動作制御をする必要がなくなり、測定者が制御手段１０から離れたところで測定している場合などであっても、制御手段１０を動作させることができる。 Furthermore, since the microphone 6 is provided in the grip portion 52 held by the hand, the trigger command T3 can be input to the microphone 6 near the hand, and the trigger command T3 can be easily input without emitting loud sound. Can be entered.
The voice processing unit 101 also generates an operation signal. Based on the operation signal, the data processing unit 103 is operated or the movable arm 42 is locked by the control means 10. For this reason, it is not necessary for the measurer to control the operation of the data processing unit 103 and the movable arm 42 by operating the control means 10 by hand during the measurement, and the measurer performs the measurement away from the control means 10. Even in such a case, the control means 10 can be operated.

＜第２実施形態＞
次に、本発明の第２実施形態について説明する。
図４に示すように、本実施形態では、第１実施形態と異なり、マイク６が制御手段１０に設けられている。マイク６は、例えば、ヘッドセットに取り付けられたマイクであり、ヘッドセットのコードなどを介して制御手段１０に接続されている。
本実施形態においても、第１実施形態と同様の動作フローによって、被測定物Ｗの外形などが測定される。 Second Embodiment

以上のような本実施形態においても、第１実施形態と同様の効果を得ることができる。また、本実施形態では、制御手段としてマイク６を備えたノート型パソコン等を利用できるため、三次元測定機１に新たな別の構成機器を追加しなくてすみ、三次元測定機１の製造コストを低減できる。   In the present embodiment as described above, the same effect as that of the first embodiment can be obtained. Further, in the present embodiment, since a notebook personal computer or the like equipped with a microphone 6 can be used as the control means, it is not necessary to add another new component device to the CMM 1, and the CMM 1 can be manufactured.

または、プローブ２や三次元測定機本体３以外の部分に、信号入力手段として、手で押圧操作して動作させる押圧スイッチが設けられていてもよい。この場合には、複数人で測定を行い、測定者以外の者がその押圧スイッチを動作させればよい。
また、トリガ指令Ｔ３は指令ではなく、例えば、単なる１つの音が発せられたものであってもよい。
また、前記各実施形態では、音声処理部１０１は、マイク６から受け取った音声信号が信号処理されて音声によって意図されていることが判別されたときに、その音声信号に基づいてトリガ信号と操作信号を生成するが、トリガ信号の生成に関しては、音声処理部１０１が、マイク６から受け取った音声信号の音量レベルが所定レベル以上のときに、その音声信号に基づいてトリガ信号を生成するようにしてもよい。 It should be noted that the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.

However, the microphone 6 is not provided, and the probe 6 and the coordinate measuring machine main body 3 are not provided. The part may be provided with a foot switch that is operated by pressing with a foot as a signal input means. In this case, when the measurement data of the measurement location is acquired, when the foot switch is pressed with the foot of the measurer, the pressing signal functions as an input signal, and a trigger signal is generated based on the pressing signal. .
Alternatively, a press switch that is operated by a manual pressing operation may be provided as a signal input unit in a portion other than the probe 2 or the CMM main body 3.
