Description
本發明係有關於一種旋轉裝置之扭力檢知器,尤指一種數位顯示之扭力檢知器,主要於轉子端可量測施加之扭力值,並採用同軸心非接觸之光電信號耦合技術,透過低功率無線傳輸特性,可將轉子端感測到的扭力值信號輸出至定子端顯示的扭力檢知器為其創新應用發明者。 The invention relates to a torsion detector of a rotating device, in particular to a digital display torque detector, which can measure the applied torque value mainly at the rotor end, and adopts a coaxial non-contact photoelectric signal coupling technology to transmit The low-power wireless transmission characteristic can output the torque value signal sensed by the rotor end to the torque detector of the stator end display for its innovative application inventor.
一般而言,對於扭力感測或檢知的需求存在於許多旋轉裝置產品之中,例如氣動工具的扭轉檢測裝置、室內運動器材之運動扭力檢測、電動螺絲起子、自行車變速齒輪之扭力感測、使用於螺絲鎖固之手動工具等等。這種旋轉裝置在使用時,會使轉動軸與外圍殼體產生持續的相對轉動運動,為了顯示旋轉裝置的轉動軸扭力值,傳統上需將扭力感測器貼附於扭力變形的轉動軸桿件上,並設置構造複雜的環式訊號拾取器,才能將轉動軸桿件感測到的扭力值信號傳輸至殼體,以便在外圍殼體顯示扭力值。 In general, the need for torque sensing or detection exists in many rotating device products, such as torsion testing devices for pneumatic tools, motion torque detection for indoor sports equipment, electric screwdrivers, torque sensing of bicycle shifting gears, Hand tools for screw locking, etc. When the rotating device is in use, the rotating shaft and the peripheral housing are continuously rotated. In order to display the rotating shaft torque value of the rotating device, the torque sensor is traditionally attached to the torsionally deformed rotating shaft. The torque signal value sensed by the rotating shaft member can be transmitted to the casing to display the torque value in the peripheral casing.
現有可顯示扭力值之扭力倍增器如台灣新型專利公告第M397882號『扭力倍增器』,即在扭力輸出軸121B貼附扭力感測器30,並於輸出軸121B外設置訊號拾取器123。該訊號拾取器123具有一連結於該輸出軸121B並隨之轉動的內環123A、一結合於該內環123A外側的中環123B,及一套接於該中環 123B外側的外環123C,經過此繞有線圈之環狀訊號拾取器123可將扭力感測器30的感測信號輸出至殼體;其主要缺點是需要設置構造複雜的環式訊號拾取器,才能將輸出桿件感測到的扭力值信號輸出至殼體,使扭力值顯示於扭力倍力器殼體的數位顯示器,而且此種線圈環繞而成的環式訊號拾取器容易受到環境磁場干擾,造成信號傳輸之不穩定。 A torque multiplier capable of displaying a torque value is, for example, a new type of patent publication No. M397882 "Torque Multiplier", that is, a torque sensor 30 is attached to the torque output shaft 121B, and a signal pickup 123 is disposed outside the output shaft 121B. The signal pickup 123 has an inner ring 123A coupled to the output shaft 121B and rotating therewith, a middle ring 123B coupled to the outer side of the inner ring 123A, and a set connected to the middle ring. The outer ring 123C on the outer side of the 123B, through which the ring-shaped signal pickup 123 wound around the coil can output the sensing signal of the torsion sensor 30 to the casing; the main disadvantage is that a loop signal pickup with complicated structure needs to be disposed. The torque value signal sensed by the output rod can be output to the housing, so that the torque value is displayed on the digital display of the torque booster housing, and the loop signal pickup surrounded by the coil is susceptible to environmental magnetic field interference. , causing instability of signal transmission.
或台灣發明專利公告第I466760號『倍力裝置』,此專利與一般扭力倍增器相同,係由行星齒輪組構成其扭力增強機構,其不同之處在於,不將扭力感測單元的應變規貼附於扭力輸出軸,而將扭力感測單元貼附於扭力倍增器的筒身,如此可以避免扭力感測單元與數位顯示單元分別處於相對迴轉運動的兩端,使扭力倍增器在使用時能夠透過筒身的反作用力變形量,同時感測扭力值並顯示於靜止端的扭力倍增器殼體表面。然而,量測扭力倍增器的輸出扭力的最準確方法需要直接將扭力感測單元直接貼附於扭力輸出軸。當此扭力感測單元被貼附於筒身時,所感測到的扭力值與輸出軸扭力值之間,會因為行星齒輪組的齒隙問題造成誤差,大幅度影響量測精準度,造成此種扭力倍增器的重大缺點。 Or Taiwan Invention Patent Notice No. I466760 "Beili Device", which is the same as a general torque multiplier, which is composed of a planetary gear set and has a torque enhancement mechanism. The difference is that the strain gauge of the torque sensing unit is not attached. Attached to the torque output shaft, and the torque sensing unit is attached to the barrel of the torque multiplier, so that the torque sensing unit and the digital display unit can be prevented from being respectively at opposite ends of the rotary motion, so that the torque multiplier can be used Through the deformation of the reaction force of the barrel, the torque value is sensed and displayed on the surface of the torsion multiplier housing at the stationary end. However, the most accurate method of measuring the output torque of a torque multiplier requires directly attaching the torque sensing unit directly to the torsion output shaft. When the torque sensing unit is attached to the barrel body, the sensed torque value and the output shaft torque value may cause errors due to the backlash problem of the planetary gear set, which greatly affects the measurement accuracy, resulting in this A major drawback of the torque multiplier.
另外,台灣新型專利公告第M406494號『倍力器構造改良(一)』,在其扭力輸出軸貼附扭力感測器,並在該扭力輸出軸設置數位顯示器,以顯示扭力倍增器的扭力值。然而,由於在操作扭力倍增器時,會使輸出桿件與扭力倍增器殼體產生持續的相對轉動運動,此設置於輸出軸的數位顯示器的持續轉動運動會阻礙使用者的扭力值觀看,在使用上甚為不便。 In addition, Taiwan's new patent announcement No. M406494 "Using the structure improvement (1)", attaches a torque sensor to its torque output shaft, and sets a digital display on the torque output shaft to display the torque value of the torque multiplier . However, since the output lever and the torsion multiplier housing generate a continuous relative rotational motion when the torque multiplier is operated, the continuous rotational movement of the digital display disposed on the output shaft hinders the user's torque value from being viewed. It is inconvenient.
還有,台灣新型專利公告第M406495號『倍力器構造改良(二)』,是在其扭力輸出軸貼附扭力感測器,並藉由無線傳輸方式將扭力值訊號穿透保護殼傳輸至扭力倍增器外部附近的物體上,以顯示器顯示扭力倍增器的輸出扭力 值。此類扭力倍增器的缺點在於所使用的無線傳輸方式耗電量很大,導致扭力感測器到無線傳輸發射器的電池更換頻繁,造成使用者的不方便。在這類扭力倍增器中,由於從無線傳輸發射器到接收端的傳輸路徑障礙較多,一般選用無線電通訊或藍牙技術進行無線傳輸,此為其功率消耗較大的主因。 In addition, Taiwan's new patent announcement No. M406495 "Using the structure improvement (2)" is to attach a torsion sensor to its torsion output shaft, and transmit the torque signal through the protective case by wireless transmission. On the object near the outside of the torque multiplier, the display shows the output torque of the torque multiplier value. The disadvantage of such a torque multiplier is that the wireless transmission method used consumes a large amount of power, resulting in frequent battery replacement of the torque sensor to the wireless transmission transmitter, which causes inconvenience to the user. In this type of torque multiplier, since the transmission path from the wireless transmission transmitter to the receiving end is more obstructive, radio communication or Bluetooth technology is generally used for wireless transmission, which is the main cause of large power consumption.
經由上述的論述,以下整理出傳統現有的「扭力檢測設備」具有以下的缺點: Through the above discussion, the following conventional "torque detecting device" has the following disadvantages:
1.為了顯示「扭力檢測設備」的輸出扭力值,一般需將扭力感測器貼附於扭力輸出桿件上,但由於在操作扭力倍增器時,會使輸出桿件與扭力倍增器殼體產生持續的相對轉動運動,為了在扭力倍增器殼體顯示扭力值,傳統「扭力倍增器」需要設置構造複雜的環式訊號拾取器,才能將輸出桿件感測到的扭力值訊號輸出至殼體,而且這種線圈環繞而成的環式訊號拾取器易受環境磁場干擾,造成信號傳輸之不穩定。 1. In order to display the output torque value of the "torque detecting device", it is generally necessary to attach the torque sensor to the torque output rod, but since the torque multiplier is operated, the output rod and the torque multiplier housing are caused. To produce a continuous relative rotational motion, in order to display the torque value in the torque multiplier housing, the conventional "torque multiplier" needs to set a complex loop signal pickup device to output the torque value signal sensed by the output rod to the shell. The ring-shaped signal pickup surrounded by the coil is susceptible to environmental magnetic fields, causing instability of signal transmission.
2.一般的無線傳輸方式需要將扭力值訊號穿透保護殼傳輸至扭力倍增器外部附近的接收器上,才能在顯示器上顯示扭力倍增器的輸出扭力值。但此類無線傳輸方式耗電量很大,導致扭力感測器到無線傳輸發射器的電池更換頻繁,造成使用者的不方便。 2. The general wireless transmission mode needs to transmit the torque signal through the protective case to the receiver near the outside of the torque multiplier to display the output torque value of the torque multiplier on the display. However, such wireless transmission methods consume a large amount of power, resulting in frequent battery replacement of the torque sensor to the wireless transmission transmitter, resulting in inconvenience to the user.
