For the description, I would like to introduce the full text into one part of the present specification.
請參閱第1圖，其係本發明之扭力控制方法之步驟圖。如圖所示，本發明之扭力控制方法包含下列步驟：(S11)設置一震動感測器於氣動衝擊式扭力工具；(S12)自氣壓系統連接氣壓管路至扭力控制裝置，於鎖固作業的起訖過程中輸出穩定的工作氣壓至氣動衝擊式扭力工具；(S13)於鎖固前，利用裝設於氣動衝擊式扭力工具出力端的扭力傳感器，以緊固件與待鎖固件先進行輸出扭力的校驗作業，依據氣動衝擊式扭力工具可正常操作的第一工作氣壓及對應的第一扭矩值與第二工作氣壓及對應的第二扭矩值，建立氣壓與扭矩的對應關係曲線；(S14)依 據對應於第一工作氣壓的第一震動頻率值及對應於第二工作氣壓的第二震動頻率值，建立氣壓與震動頻率的對應關係曲線；(S15)輸入介於第一與第二扭矩值之間的目標扭矩值，依據氣壓與扭矩的對應關係曲線以得到對應的工作氣壓值，並以該工作氣壓驅動氣動衝擊式扭力工具進行鎖固作業；以及(S16)依據震動感測器感測的工作震動頻率值及氣壓與震動頻率的對應關係曲線，判斷以該工作氣壓驅動氣動衝擊式扭力工具進行鎖固作業時，對應之震動值是否符合目標扭矩值。 Please refer to Fig. 1, which is a step diagram of the torque control method of the present invention. As shown in the figure, the torque control method of the present invention comprises the following steps: (S11) setting a vibration sensor to a pneumatic impact type torque tool; (S12) connecting a pneumatic line from a pneumatic system to a torque control device for locking operation During the creping process, the stable working pressure is output to the pneumatic impact type torque tool; (S13) before the locking, the torque sensor installed at the output end of the pneumatic impact type torque tool is used to output the torque firstly with the fastener and the firmware to be locked. The calibration operation establishes a corresponding relationship between the air pressure and the torque according to the first working air pressure and the corresponding first torque value and the second working pressure and the corresponding second torque value that can be normally operated by the pneumatic impact type torque tool; (S14) according to Corresponding relationship between the air pressure and the vibration frequency is established according to the first vibration frequency value corresponding to the first working air pressure and the second vibration frequency value corresponding to the second working air pressure; (S15) inputting the first and second torque values The target torque value is based on the corresponding relationship between the air pressure and the torque to obtain a corresponding working air pressure value, and the pneumatic impact type torque tool is driven by the working air pressure to perform the locking operation; and (S16) sensing according to the vibration sensor The working vibration frequency value and the corresponding relationship between the air pressure and the vibration frequency determine whether the corresponding vibration value meets the target torque value when the pneumatic impact type torque tool is driven by the working air pressure to perform the locking operation.
簡單來說，本發明之扭力控制方法係藉由震動感測器設置於氣動衝擊式扭力工具上，從而在建立氣壓與扭矩的對應關係曲線時，可一併建立一接近線性的氣壓與震動頻率的對應關係曲線(如第9圖所示)。因此，在以對應目標扭矩值的工作氣壓進行鎖固作業時，可一併利用震動感測器感測到的震動頻率值同時驗證是否與目標扭矩值符合。 Briefly, the torque control method of the present invention is provided on the pneumatic impact type torque tool by the vibration sensor, so that when the corresponding relationship between the air pressure and the torque is established, a nearly linear air pressure and vibration frequency can be established together. Correspondence curve (as shown in Figure 9). Therefore, when the locking operation is performed at the working air pressure corresponding to the target torque value, the vibration frequency value sensed by the vibration sensor can be used together to verify whether it matches the target torque value.
順便一提的是，在建立氣壓與扭矩的對應關係曲線與氣壓與震動頻率的對應關係曲線中所使用的第一工作氣壓與第二工作氣壓，其中第一工作氣壓不等於第二工作氣壓。且較佳地，第一工作氣壓可為在可穩定輸出的工作氣壓中的最高工作氣壓，而第二工作氣壓可為在可穩定輸出的工作氣壓中的最低工作氣壓。另外，由於第一工作氣壓為該氣動衝擊式扭力工具可容許的最高工作氣壓，而第二工作氣壓值為該氣動衝擊式扭力工具可正常操作的最低工作氣壓，因此第一扭矩值可為最大扭矩值，而第二扭矩值可為最小扭矩值。 Incidentally, the first working air pressure and the second working air pressure used in establishing a correspondence curve between the air pressure and the torque and the relationship between the air pressure and the vibration frequency, wherein the first working air pressure is not equal to the second working air pressure. And preferably, the first working air pressure may be the highest working air pressure in the working air pressure that can be stably output, and the second working air pressure may be the lowest working air pressure in the working air pressure that can be stably outputted. In addition, since the first working air pressure is the highest working air pressure that the pneumatic impact type torque tool can tolerate, and the second working air pressure value is the lowest working air pressure that the pneumatic impact type torque tool can operate normally, the first torque value can be the maximum The torque value, and the second torque value may be the minimum torque value.
請配合參閱第2、3圖。如第3圖之步驟S31~32所示，於鎖固前先進行輸出扭力的校驗作業時，若當輸出入模組26的自動設定鈕30 被觸發，微處理器25可自動地以設定的程式控制，由第二工作氣壓52逐步提升至第一工作氣壓51，或由第一工作氣壓51逐步調降至第二工作氣壓52，以建立氣壓與扭矩的對應關係曲線57及氣壓與震動頻率的對應關係曲線58。為了利用扭力控制裝置的自動調壓模組以便在無法達到目標扭矩值時，可透過微處理器以設定的程式將氣壓自動向上微調，直到目標扭矩值時，始切斷氣源或於最終仍無法達到目標扭力時，提出警示並切斷氣源。為此一目的，實際開始操作的工作氣壓則視需要可設定為較氣動衝擊式扭力工具可容許的最高工作氣壓低10~20%。 Please refer to Figures 2 and 3 together. As shown in steps S31-32 of FIG. 3, when the output torque is verified before the locking, the automatic setting button 30 of the input/output module 26 is output. When triggered, the microprocessor 25 can be automatically controlled by a set program, gradually increased from the second working air pressure 52 to the first working air pressure 51, or gradually reduced from the first working air pressure 51 to the second working air pressure 52 to establish Correspondence curve 57 between air pressure and torque and a corresponding relationship curve 58 between air pressure and vibration frequency. In order to utilize the automatic pressure regulating module of the torque control device, when the target torque value cannot be reached, the air pressure can be automatically fine-tuned by the microprocessor in a set program until the target torque value is turned off, or the gas source is still unable to be finally obtained. When the target torque is reached, alert and cut off the air supply. For this purpose, the working air pressure that actually starts operating can be set to be 10-20% lower than the maximum working air pressure that can be tolerated by the pneumatic impact torque tool as needed.
其中，若為手動方式時，當然地為以手動方式調節氣壓至第一工作氣壓51以獲得第一扭矩值53與第一震動頻率值55，再調節氣壓至第二工作氣壓52以獲得第二扭矩值54與第二震動頻率值56，分別取其高、低兩點間之連結，以建立氣壓與扭矩的對應關係曲線57及氣壓與震動頻率的對應關係曲線58。 Wherein, in the manual mode, it is of course to manually adjust the air pressure to the first working air pressure 51 to obtain the first torque value 53 and the first vibration frequency value 55, and then adjust the air pressure to the second working air pressure 52 to obtain the second. The torque value 54 and the second vibration frequency value 56 are respectively connected between the high and low points to establish a correlation curve 57 between the air pressure and the torque and a corresponding relationship curve 58 between the air pressure and the vibration frequency.
本發明之扭力控制方法可應用於扭力控制系統8。扭力控制系統8包含扭力傳感器4、震動感測器5與扭力控制裝置2。扭力控制裝置2主要為連接於一氣壓系統1與氣動衝擊式扭力工具3之間。扭力控制裝置2主要包含了進氣壓力監控模組21、氣壓調節模組22、電磁閥23、記憶單元28及微處理器25，而另可包含顯示模組27、警示單元29及輸出入模組26等元件。氣壓調節模組22可包含自動或手動調壓模組、氣壓比例控制閥、氣壓壓力控制閥等元件，於此便不再加以贅述。 The torque control method of the present invention can be applied to the torque control system 8. The torque control system 8 includes a torque sensor 4, a vibration sensor 5, and a torque control device 2. The torque control device 2 is mainly connected between the one air pressure system 1 and the pneumatic impact type torque tool 3. The torque control device 2 mainly includes an intake pressure monitoring module 21, a gas pressure adjusting module 22, a solenoid valve 23, a memory unit 28 and a microprocessor 25, and may further include a display module 27, a warning unit 29, and an output module. Group 26 and other components. The air pressure adjustment module 22 may include components such as an automatic or manual pressure regulating module, a pneumatic proportional control valve, a pneumatic pressure control valve, and the like, and will not be further described herein.
震動感測器5係設置於氣動衝擊式扭力工具3(如氣動衝擊式扭力工具)上，而扭力傳感器4裝設於氣動衝擊式扭力工具3之出力端， 其以有線或無線的方式連接微處理器25；其中震動感測器、扭力傳感器與扭力控制裝置相互之間各以通訊模組，利用有線或無線傳輸的方式通訊，例如RS232、RS485、USB和相關通訊協定RF、BT、WIFI、ZB等。 而震動感測器5可包含加速規等可感測工具的震動頻率的感測元件、訊號放大電路、微處理器、電源或傳輸模組等元件等，且其以有線或無線傳輸的方式連接微處理器25。 The vibration sensor 5 is disposed on the pneumatic impact type torque tool 3 (such as a pneumatic impact type torque tool), and the torque sensor 4 is mounted on the output end of the pneumatic impact type torque tool 3, It is connected to the microprocessor 25 by wire or wirelessly; wherein the vibration sensor, the torque sensor and the torque control device communicate with each other by means of wired or wireless transmission, such as RS232, RS485, USB and Related communication protocols RF, BT, WIFI, ZB, etc. The vibration sensor 5 may include a sensing component such as an acceleration gauge and a vibration frequency of the sensing tool, a signal amplifying circuit, a microprocessor, a power supply or a transmission module, etc., and the wired sensor or the wireless transmission method is connected. Microprocessor 25.
進氣壓力監控模組21控制自氣壓系統1進入扭力控制裝置2的空氣壓力，或在進氣超出扭力控制裝置2之壓力上限時利用警示模組29提出警示。氣壓調節模組22調節輸出至氣動衝擊式扭力工具3之一氣壓值。電磁閥23開啟或切斷輸出至氣動衝擊式扭力工具3之氣壓源。 The intake pressure monitoring module 21 controls the air pressure entering the torque control device 2 from the air pressure system 1, or uses the warning module 29 to raise an alarm when the intake air exceeds the upper pressure limit of the torque control device 2. The air pressure adjusting module 22 adjusts the air pressure value output to one of the pneumatic impact type torque tools 3. The solenoid valve 23 opens or cuts off the air pressure output to the pneumatic impact type torque tool 3.
記憶單元28儲存氣動衝擊式扭力工具3在穩定工作氣壓範圍內，在進行正式鎖固作業前，對同一規格、類型的緊固件與待鎖固件分別以第一工作氣壓51與第二工作氣壓52校驗取得分別對應的第一扭矩值53與第二扭矩值54，及震動感測器5感測到的對應於第一工作氣壓51的第一震動頻率值55與對應於第二工作氣壓52的一第二震動頻率值56。 微處理器25依據校驗獲得的第一工作氣壓51、第二工作氣壓52、第一扭矩值53與第二扭矩值54，建立一氣壓與扭矩的對應關係曲線57，且依據第一工作氣壓51、第二工作氣壓52與第一震動頻率值55、第二震動頻率值56，建立一氣壓與震動頻率的對應關係曲線58。因此，在正式進行鎖固作業時，微處理器25可依據第一與該第二扭矩值53、54內輸入的一目標扭矩值，經由氣壓與扭矩的對應關係曲線57上取得對應目標扭矩值的一工作氣壓，微處理器25再依據該工作氣壓來驅動氣動衝擊式扭力工具3 以進行鎖固作業。接著，微處理器25可再依據震動感測器5感測的震動頻率值，依氣壓與震動頻率的對應關係曲線58，藉以同時判斷該感測的震動頻率值是否與目標扭矩值相符。 The memory unit 28 stores the pneumatic impact type torque tool 3 in the stable working pressure range, and before the formal locking operation, the first working air pressure 51 and the second working air pressure are respectively applied to the same specification and type of fasteners and the to-be-locked firmware. The calibration obtains the corresponding first torque value 53 and second torque value 54 respectively, and the first vibration frequency value 55 corresponding to the first working air pressure 51 sensed by the vibration sensor 5 and corresponds to the second working air pressure 52 A second vibration frequency value of 56. The microprocessor 25 establishes a corresponding relationship curve 57 between the air pressure and the torque according to the first working air pressure 51, the second working air pressure 52, the first torque value 53 and the second torque value 54 obtained by the verification, and according to the first working air pressure. 51. The second working air pressure 52 and the first vibration frequency value 55 and the second vibration frequency value 56 establish a corresponding relationship curve 58 between the air pressure and the vibration frequency. Therefore, when the locking operation is officially performed, the microprocessor 25 can obtain the corresponding target torque value via the corresponding relationship curve 57 between the air pressure and the torque according to a target torque value input in the first and second torque values 53 and 54. At a working pressure, the microprocessor 25 drives the pneumatic impact torque tool according to the working air pressure. For locking work. Then, the microprocessor 25 can further determine whether the sensed vibration frequency value matches the target torque value according to the vibration frequency value sensed by the vibration sensor 5 and the corresponding relationship curve 58 between the air pressure and the vibration frequency.
在實際運用中，微處理器25同時依據扭力傳感器4所感測到的應變值及氣壓與震動頻率的對應關係曲線58獲得的震動頻率值，以判斷該感測的震動頻率值是否符合目標扭矩值。如此，同時利用二者來判斷鎖固作業是否符合目標扭矩值，可增進扭矩控制的精確度。當然地，亦可選擇性地僅使用其中一種方式來判斷鎖固作業是否符合目標扭矩值。舉例來說，微處理器25可僅依據扭力的應變值，或者僅依據震動的頻率感測值，來判斷鎖固作業是否符合目標扭矩值。由於扭力傳感器4為價格較為昂貴的元件，且在長時間劇烈衝擊的鎖固作業下容易造成損壞，因此若於完成校驗後，移除扭力傳感器4，僅依據震動感測器來偵測震動頻率值，仍可做閉迴路的控制，來判斷鎖固作業否符合目標扭矩值，除了可減少購置成本，且適用於受操作空間限制，無法使用扭力傳感器的作業場所。 In practical use, the microprocessor 25 simultaneously determines the vibration frequency value obtained according to the strain value sensed by the torque sensor 4 and the corresponding relationship curve 58 between the air pressure and the vibration frequency to determine whether the sensed vibration frequency value meets the target torque value. . In this way, the use of both to determine whether the locking operation meets the target torque value can improve the accuracy of the torque control. Of course, it is also possible to selectively use only one of the methods to determine whether the locking operation meets the target torque value. For example, the microprocessor 25 can determine whether the locking operation conforms to the target torque value based solely on the strain value of the torsion or only based on the frequency sensing value of the vibration. Since the torsion sensor 4 is a relatively expensive component and is liable to be damaged under a long-term severe impact locking operation, if the torsion sensor 4 is removed after the verification is completed, the vibration is detected only by the vibration sensor. The frequency value can still be controlled by closed loop to judge whether the locking operation meets the target torque value, in addition to reducing the purchase cost, and it is suitable for the working place where the torque sensor cannot be used due to the limitation of the operating space.
此外，在上述之自動模式中，氣壓調節模組22包含自動調壓模組、氣壓比例控制閥、氣壓壓力控制閥，此時微處理器25可控制先以低於對應於目標扭矩值的工作氣壓驅動氣動衝擊式扭力工具3，再藉由氣壓比例控制閥、氣壓壓力控制閥自動地調高至對應於目標扭矩值的工作氣壓，以避免啟動瞬間造成過扭。甚至於，可進一步依據扭力傳感器4所感測到的應變值、查詢氣壓與震動頻率的對應關係曲線58獲得的震動頻率值或兩者之組合，而自動地調整至對應於目標扭矩值的工作氣壓。 其中，若在作業空間受限的情況下，於移除扭力傳感器4後，仍可藉已建立的氣壓與扭矩的對應關係曲線57及氣壓與震動頻率的對應關係曲線58，進行閉迴路的扭控鎖固作業。 In addition, in the above automatic mode, the air pressure adjusting module 22 includes an automatic pressure regulating module, a pneumatic proportional control valve, and a pneumatic pressure control valve. At this time, the microprocessor 25 can control the work below the target torque value. The pneumatically driven pneumatic impact type torque tool 3 is automatically adjusted up to the working pressure corresponding to the target torque value by the pneumatic proportional control valve and the pneumatic pressure control valve to avoid over-twisting at the moment of starting. Even further, according to the strain value sensed by the torque sensor 4, the vibration frequency value obtained by querying the corresponding relationship curve 58 of the air pressure and the vibration frequency, or a combination of the two, the working pressure corresponding to the target torque value is automatically adjusted. . Wherein, if the working space is limited, after the torque sensor 4 is removed, the closed curve of the closed loop can be performed by the established relationship curve 57 between the air pressure and the torque and the corresponding relationship curve 58 between the air pressure and the vibration frequency. Control lock operation.

在實際運用中，鎖固作業可分別設有扭矩模式、時間與扭矩模式、扭矩與角度模式、及時間、扭矩與角度模式等多種鎖固模式，以因應各種鎖固作業對所使用的緊固件與待鎖固件的品質規範等的需求，分別進行說明如下。 In actual operation, the locking operation can be provided with various locking modes such as torque mode, time and torque mode, torque and angle mode, and time, torque and angle mode, in order to respond to various fasteners. The requirements of the quality specifications of the firmware to be locked, etc., are respectively described below.
請參閱第5圖。如圖步驟S51~S52所示，若以扭矩模式進行鎖固時，在進行鎖固作業開始時，微處理器25依據對應目標扭矩值的工作氣壓控制電磁閥23驅動氣動衝擊式扭力工具3。同時，扭力傳感器4會持續地將感測到的扭力應變值傳送至微處理器25，而微處理器25會持續地比對扭力應變值是否符合或已達目標扭矩值；當微處理器25判斷扭力應變值符合或已達目標扭矩值時，控制電磁閥23切斷輸出至氣動衝擊式扭力工具3的氣壓源，以完成鎖固作業並判定鎖固作業合格。 Please refer to Figure 5. As shown in steps S51 to S52, when the locking is performed in the torque mode, the microprocessor 25 controls the electromagnetic valve 23 to drive the pneumatic impact type torque tool 3 in accordance with the operating air pressure corresponding to the target torque value at the start of the locking operation. At the same time, the torque sensor 4 will continuously transmit the sensed torque strain value to the microprocessor 25, and the microprocessor 25 will continuously compare the torque strain value to or have reached the target torque value; when the microprocessor 25 When it is judged that the torque strain value meets or has reached the target torque value, the control solenoid valve 23 cuts off the air pressure source output to the pneumatic impact type torque tool 3 to complete the locking operation and determine that the locking work is qualified.
請參閱第6圖。如圖步驟S61~62所示，若以時間與扭矩模式進行鎖固時，在進行鎖固作業開始時，扭力傳感器4會持續地將感測到的扭力應變值傳送至微處理器25，而微處理器25會不斷的比對扭力應變值是否符合或已達目標扭矩值；同時地，微處理器25會自電磁閥23開始驅動氣動衝擊式扭力工具3起累計一鎖固時間，且比對鎖固時間是否符合預定的鎖固時間範圍。當微處理器25判斷扭力應變值已達目標扭矩值，且鎖固時間符合預定的時間範圍內時，控制電磁閥23立即切斷輸出至氣動衝擊式扭力工具3的氣壓源，完成鎖固作業並判定鎖固作業合格。 Please refer to Figure 6. As shown in steps S61-62, when the lock is performed in the time and torque mode, the torque sensor 4 continuously transmits the sensed torque strain value to the microprocessor 25 at the start of the lock operation. The microprocessor 25 will continuously compare whether the torque strain value meets or has reached the target torque value; meanwhile, the microprocessor 25 will start to drive the pneumatic impact torque tool 3 from the solenoid valve 23 to accumulate a lock time, and the ratio Whether the locking time meets the predetermined locking time range. When the microprocessor 25 determines that the torque strain value has reached the target torque value and the locking time is within the predetermined time range, the control solenoid valve 23 immediately cuts off the air pressure output to the pneumatic impact torque tool 3 to complete the locking operation. And it is determined that the locking work is qualified.
請參閱第7圖。如圖步驟S71~73所示，對於扭矩的比對與判斷，如前所述，於此便不再贅述。若以角度與扭矩模式進行鎖固時，氣動衝擊式扭力工具3可利用與扭力傳感器4內建的角度感測器6。在進行鎖固作業時，當緊固件鎖至與待鎖固件貼面的瞬間，扭力傳感器4所感測到的扭力應變值會產生一明顯的峰值；此時，微處理器25則依角度感測器6開始感測的旋轉角度，比對鎖固角度值是否達到預定的鎖固角度範圍內。當微處理器25判斷扭力應變值已達目標扭矩值，且鎖固角度位移達到預定的鎖固角度範圍內時，控制電磁閥23切斷輸出至氣動衝擊式扭力工具3的氣壓源，以完成鎖固作業並判定鎖固作業合格。 Please refer to Figure 7. As shown in steps S71-73, the comparison and determination of the torque are as described above, and will not be described again. The pneumatic impact type torque tool 3 can utilize the angle sensor 6 built into the torsion sensor 4 when locked in the angle and torque mode. During the locking operation, when the fastener is locked to the surface to be locked, the torque strain value sensed by the torque sensor 4 generates a significant peak value; at this time, the microprocessor 25 senses the angle. The 6 starts to sense the angle of rotation, and whether the value of the locking angle reaches a predetermined locking angle range. When the microprocessor 25 determines that the torque strain value has reached the target torque value, and the locking angle displacement reaches a predetermined locking angle range, the control solenoid valve 23 cuts off the air pressure source output to the pneumatic impact type torque tool 3 to complete Lock the work and determine that the locking work is qualified.
請參閱第8圖。如圖步驟S81~84所示，其中，對於扭矩、角度與時間的比對與判斷，如前所述，於此便不再贅述。簡而言之，微處理器25判斷扭力應變值達到目標扭矩值時，鎖固角度值符合預定的鎖固角度範圍內，以及鎖固時間值亦符合預定的鎖固時間範圍內時，判斷鎖固作業合格。值得一提的是，鎖固角度值符合預定鎖固角度值及鎖固 時間值符合預定鎖固時間值，其可具有容許合格範圍，例如±10%，皆可判定為合格。藉此，以忽略緊固件與待鎖固件無法避免的因軟硬結合面等的差異性所產生的數值差異。 Please refer to Figure 8. As shown in steps S81-84, the comparison and determination of the torque, the angle and the time are as described above. In short, when the microprocessor 25 determines that the torque strain value reaches the target torque value, the lock angle value meets the predetermined lock angle range, and the lock time value also meets the predetermined lock time range, the lock is judged. The solid work is qualified. It is worth mentioning that the locking angle value meets the predetermined locking angle value and locks. The time value is in accordance with a predetermined lock time value, which may have an acceptable acceptance range, for example, ±10%, which may be judged as pass. Thereby, the numerical difference caused by the difference between the fastener and the soft and hard joint surface which cannot be avoided by the fastener to be locked is ignored.
綜上所述，本發明的扭力控制方法及其扭力控制系統，更進一步利用氣動衝擊式扭力工具3裝設的震動感測器5測得的震動頻率值，以判定鎖固作業是否達到目標扭矩值。藉此可有效的增進控制扭矩的精確度。更得以在作業空間受限的情況下，於移除扭力傳感器4後，仍可藉已建立的氣壓與扭矩的對應關係曲線57及氣壓與震動頻率的對應關係曲線58，進行閉迴路的扭控鎖固作業。另外，亦可將扭力控制裝置內同樣的功能模組，例如顯示單元、記憶單元、輸出入模組、警示單元、微處理器等另增設於便攜式電子裝置或穿戴式電子裝置7，並與扭力控制裝置以無線通訊傳輸，藉此可有效的增加使用上的便利性。此外，可藉由自動設定模式而自動地建立氣壓與扭矩的對應關係曲線及氣壓與震動頻率的對應關係曲線，藉此可有效的增加操作上的便利性。而在鎖固作業中，本發明的扭力控制方法及其扭力控制系統可具有多種鎖固模式的配置，藉此可增加本發明的扭力控制方法及其扭力控制系統的應用層面，從而可有效的增加實用性及使用上的便利性。 In summary, the torque control method and the torque control system thereof of the present invention further utilize the vibration frequency value measured by the vibration sensor 5 installed in the pneumatic impact type torque tool 3 to determine whether the locking operation reaches the target torque. value. Thereby, the accuracy of the control torque can be effectively improved. Moreover, in the case where the working space is limited, after the torque sensor 4 is removed, the closed loop torque control can still be performed by the established relationship curve 57 between the air pressure and the torque and the corresponding relationship curve 58 between the air pressure and the vibration frequency. Locking work. In addition, the same functional modules in the torque control device, such as a display unit, a memory unit, an input/output module, a warning unit, a microprocessor, etc., may be additionally added to the portable electronic device or the wearable electronic device 7, and the torque The control device transmits in wireless communication, thereby effectively increasing the convenience in use.
