Description
本發明係關於一種檢測裝置，尤指一種工具機之刀具檢測裝置。The invention relates to a detecting device, in particular to a tool detecting device for a machine tool.
於機械加工過程中，由於刀具老化、殘留切屑干擾、切削強度過高等因素之影響，可能會導致刀具斷裂，倘若不能及時發現刀具受損並進行更換，會影響物件加工精度，因此，需要由現場工作人員經常檢查並作更換，所以加工現場都需有工作人員一直待在現場，導致高人事成本之支出。In the machining process, due to factors such as aging of the tool, residual chip interference, and high cutting strength, the tool may be broken. If the tool is not damaged and replaced in time, it will affect the machining accuracy of the object. Therefore, it is necessary to The staff often checks and replaces them, so the processing site needs to have staff staying on site, resulting in high personnel costs.
若物件需高精度加工時，由於已斷刀之刀具難以用肉眼判斷，又未即時作刀具更換，便進行加工，導致加工後之物件不符精度需求，而需重新加工或淘汰情形，進而造成加工成本之增加。If the object needs high-precision machining, the tool that has been broken is difficult to judge with the naked eye, and the tool is not replaced immediately, so that the processed object does not meet the precision requirements, but needs to be reworked or eliminated, resulting in processing. The increase in cost.
另外，刀具於加工過程中，可能因為切削阻力，使刀具被夾持之力量減弱，導致刀具之突出量過多，因此，於再次加工時，突出之刀具會影響加工精度，或是導致物件、刀具損害，造成加工成本之增加。In addition, during the machining process, the tool may be weakened due to the cutting resistance, resulting in too much protrusion of the tool. Therefore, when reworking, the protruding tool may affect the machining accuracy or cause the object or tool. Damage, resulting in an increase in processing costs.
再者，中華民國專利第I567515號，揭示一種刀具磨損率監控系統，其利用影像方式判斷刀具是否有斷刀情形，但是，利用影像方式，需架設過多攝影裝置及判斷機台，造成檢測成本過高，而且需佔據過多使用空間，於使用上較不便利；而且，大多工具機於加工過程中，需使用切削液做為潤滑作用，為防止切削液噴濺損壞攝影裝置，需於攝影裝置增加防水措施，造成檢測使用上之諸多不便。Furthermore, the Republic of China Patent No. I567515 discloses a tool wear rate monitoring system which uses an image method to determine whether a tool has a broken knife. However, by using an image method, it is necessary to set up too many photographic devices and determine the machine, resulting in a cost of detection. High, and need to occupy too much space for use, it is not convenient to use; Moreover, most of the machine tools need to use cutting fluid as lubrication during the processing, in order to prevent the cutting fluid from splashing and damage the photographic device, it needs to be added to the photographic device. Waterproof measures cause a lot of inconvenience in the use of testing.
因此，如何改善前述之缺點，提供一種能夠檢測刀具斷刀或突刀情形之裝置，有待相關業者解決之。Therefore, how to improve the aforementioned shortcomings and provide a device capable of detecting a knife break or a knives situation is to be solved by a related industry.

The sensor 10 is provided with an electrical component 11 and a control component 12, and the control component 12 corresponds to the machining end 3a of the tool 3. When the machining end 3a of the tool 3 contacts the control component 12, the control component 12 corresponds to the electrical component. 11. The electrical component 11 causes the electrical component 11 to generate a contact signal based on the force of contact of the tool 3. Wherein, the electrical component 11 is a pressure sensing component, the contact signal is a voltage value, and the tool 3 contacts the force of the sensor 10 to determine the size of the contact signal.

The sensor 10 is provided with a movable piece 13 and a contact member 14, and the movable piece 13 is connected with the control member 12. The contact member 14 is coupled to the electrical component 11 and the electrical component 11 is disposed between the movable panel 13 and the contact member 14. When the mobile platform 4 drives the sensor 10 to move under the machining end 3a of the tool 3, and the machining end 3a of the spindle driving tool 3 of the machine tool 1 moves toward the control contact 12 and contacts the pressure control contact 12, the touch is controlled.

一控制器30，其訊號連結傳感器10與可程式邏輯控制器2間，於本發明實施例中，控制器30設於可程式邏輯控制器2內部，且控制器30與傳感器10及可程式邏輯控制器2係有線訊號連結。控制器30設有一檢測時間，於檢測時間，控制器30用以接收接觸訊號，而控制器30根據接觸訊號判斷刀具3呈正常狀態、突刀狀態或斷刀狀態，其中，控制器30根據接觸訊號分為一正常訊號值及一異常訊號值，正常訊號值小於異常訊號值，正常訊號值係刀具3呈正常狀態，異常訊號值係刀具3呈突刀狀態，表示刀具3之突出量過多；於檢測時間，控制器30未接收到接觸訊號，控制器30則判斷刀具3呈斷刀狀態。A controller 30, between the signal connection sensor 10 and the programmable logic controller 2, in the embodiment of the invention, the controller 30 is disposed inside the programmable logic controller 2, and the controller 30 and the sensor 10 and the programmable logic Controller 2 is a wired signal link. The controller 30 is provided with a detection time. During the detection time, the controller 30 is configured to receive the contact signal, and the controller 30 determines, according to the contact signal, that the tool 3 is in a normal state, a knife state or a broken state, wherein the controller 30 is in contact according to the contact. The signal is divided into a normal signal value and an abnormal signal value. The normal signal value is smaller than the abnormal signal value. The normal signal value is the normal state of the tool 3, and the abnormal signal value is the tool 3 state, indicating that the protruding amount of the tool 3 is excessive; At the detection time, the controller 30 does not receive the contact signal, and the controller 30 determines that the tool 3 is in the broken state.
控制器30具有一時間單元31及一接收單元32，時間單元31對應連結可程式邏輯控制器2，時間單元31用以設定一檢測次數及對應該檢測次數之檢測時間，其中，檢測次數及檢測時間係對應可程式邏輯控制器2根據所需加工物件之數量及流程所作設定，而接收單元32根據時間單元31設定之檢測次數，於設定之檢測時間接收接觸訊號，例如：所需加工之物件為10件，刀具3所需加工之次數為10次，每次加工之時間為2秒，於刀具3加工後，需檢測刀具3狀態，每次檢測所需花費時間為1秒，因此，對應前述加工檢測流程，時間單元31設定檢測次數為10次，時間單元31設定檢測時間為開始加工後之第2秒、第5秒、第8秒、……至第30秒，接收單元32於檢測時間各接收接觸訊號一次。The controller 30 has a time unit 31 and a receiving unit 32. The time unit 31 is coupled to the programmable logic controller 2, and the time unit 31 is configured to set a detection time and a detection time corresponding to the number of detections, wherein the detection times and detections are performed. The time corresponds to the programmable logic controller 2 according to the number and flow of the required processed objects, and the receiving unit 32 receives the contact signal according to the detected number of times set by the time unit 31, for example, the object to be processed. For 10 pieces, the number of times the tool 3 needs to be machined is 10 times, and the time for each machining is 2 seconds. After the tool 3 is machined, the state of the tool 3 needs to be detected, and the time required for each test is 1 second. Therefore, corresponding In the processing detection process, the time unit 31 sets the number of detections to 10 times, and the time unit 31 sets the detection time to the second, fifth, eighth, ... to 30th seconds after the start of processing, and the receiving unit 32 detects Each time receives a contact signal once.
控制器30設有一判斷單元33，用以根據接收單元32是否傳送之接觸訊號判斷刀具3為正常狀態、突刀狀態或斷刀狀態。判斷單元33設有一基礎值，當接收單元32於檢測時間接收到接觸訊號，並將接觸訊號傳送至判斷單元33，而判斷單元33將接觸訊號與基礎值比較，當接觸訊號小於基礎值時，則判斷單元33將接觸訊號分為正常訊號值，並表示刀具3呈正常狀態；當接觸訊號大於基礎值時，則判斷單元33將接觸訊號分為異常訊號值，並表示刀具3呈突刀狀態。另外，於本發明另一實施例中，若是接觸訊號過小於基礎值時，判斷單元33將接觸訊號分為異常訊號值，並表示刀具3呈斷刀狀態，換言之，刀具3之斷刀狀態僅磨損，於刀具3朝控觸件12方向移動並接觸時，依然能夠接觸控觸件12，但接觸力量過小，因此，接觸訊號會過小於基礎值。此外，如圖1及圖5，若是於檢測時間，接收單元32未接收到接觸訊號，表示刀具3之加工端3a未抵壓控觸件12，電氣元件11便無法產生接觸訊號，而接收單元32傳送一斷刀訊號至判斷單元33，判斷單元33根據斷刀訊號判斷刀具3為斷刀狀態。The controller 30 is provided with a determining unit 33 for determining whether the tool 3 is in a normal state, a knife state or a broken state according to whether the receiving unit 32 transmits a contact signal. The determining unit 33 is provided with a basic value. When the receiving unit 32 receives the contact signal at the detecting time, and transmits the contact signal to the determining unit 33, the determining unit 33 compares the contact signal with the basic value. When the contact signal is less than the basic value, Then, the determining unit 33 divides the contact signal into normal signal values, and indicates that the tool 3 is in a normal state; when the contact signal is greater than the basic value, the determining unit 33 divides the contact signal into abnormal signal values, and indicates that the tool 3 is in a protruding state. . In addition, in another embodiment of the present invention, if the contact signal is less than the basic value, the determining unit 33 divides the contact signal into an abnormal signal value, and indicates that the tool 3 is in a broken state, in other words, the cutting state of the tool 3 is only Wear and tear, when the tool 3 moves and contacts in the direction of the control member 12, the contact member 12 can still be contacted, but the contact force is too small, so the contact signal will be less than the basic value. In addition, as shown in FIG. 1 and FIG. 5, if the receiving unit 32 does not receive the contact signal during the detection time, indicating that the processing end 3a of the tool 3 does not press the control member 12, the electrical component 11 cannot generate the contact signal, and the receiving unit 32 transmits a broken knife signal to the judging unit 33, and the judging unit 33 judges that the tool 3 is in the broken state according to the broken knife signal.
控制器30具有一警示單元34，當判斷單元33判斷刀具3係斷刀狀態或突刀狀態時，警示單元34發出一警示訊號，而警示訊號同時送至可程式邏輯控制器2，當可程式邏輯控制器2接收到警示訊號，便立即停止工具機1加工作業，並提醒現場工作人員，目前刀具3為斷刀狀態或突刀狀態，需進行刀具3更換，以確保損壞刀具3不再繼續作業加工。The controller 30 has a warning unit 34. When the determining unit 33 determines that the tool 3 is in a broken state or a knife state, the warning unit 34 sends a warning signal, and the warning signal is simultaneously sent to the programmable logic controller 2, when the program is programmable. When the logic controller 2 receives the warning signal, it immediately stops the machining operation of the machine tool 1, and reminds the field staff that the current tool 3 is in the state of the broken knife or the knife, and the tool 3 needs to be replaced to ensure that the damaged tool 3 does not continue.

因此，藉由刀具3之加工端3a與傳感器10接觸與否以及接觸訊號，判斷刀具3為正常狀態、突刀狀態或斷刀狀態，藉此，以機械作動方式搭配控制器30作為刀具3狀態之檢測手段，能夠減少降低設置檢測裝置之成本費用，且體積小不佔空間；另外以機械作動方式不易損壞，使用壽命長。Therefore, by the contact of the machining end 3a of the tool 3 with the sensor 10 and the contact signal, it is determined that the tool 3 is in a normal state, a knive state or a broken state, whereby the controller 30 is mechanically actuated as the tool 3 state. The detection means can reduce the cost and cost of setting the detection device, and the volume is small and does not occupy space; in addition, it is not easy to be damaged by mechanical operation and has a long service life.
再者，若是判斷單元33判斷刀具3為突刀或斷刀狀態，警示單元34便傳送警示訊號至可程式邏輯控制器2，而可程式邏輯控制器2便立即停止工具機1作動，由工作人員進行換刀作業，防止異常刀具3繼續加工，造成物件或刀具3損壞，以確保加工品質。Moreover, if the determining unit 33 determines that the tool 3 is in a knives or a broken state, the warning unit 34 transmits an alert signal to the programmable logic controller 2, and the programmable logic controller 2 immediately stops the working of the machine tool 1 by working. The person performs the tool change operation to prevent the abnormal tool 3 from continuing to be processed, resulting in damage to the object or the tool 3 to ensure the processing quality.
另外，藉由電氣元件11將刀具3之加工端3a與傳感器10接觸時之力量傳送至控制器30，由判斷單元33根據接觸訊號之大小，判斷接觸訊號為正常訊號值或異常訊號值，便能夠精確判斷出刀具3是否為突刀狀態或斷刀狀態，若為突刀狀態或斷刀狀態便能藉由警示單元34發送警示訊號，停止工具機1作動，藉此，以防止刀具3繼續進行加工，避免刀具3或物件之損壞，以確保加工品質。In addition, the power when the processing end 3a of the tool 3 is in contact with the sensor 10 is transmitted to the controller 30 by the electrical component 11, and the judging unit 33 judges whether the contact signal is a normal signal value or an abnormal signal value according to the magnitude of the contact signal. It can accurately determine whether the tool 3 is in the state of the blade or the state of the knife. If the blade state or the state of the knife is broken, the warning unit 34 can send the warning signal to stop the operation of the machine tool 1 to prevent the tool 3 from continuing. Machining is performed to avoid damage to the tool 3 or the object to ensure the quality of the process.
