Description
本創作係關於一種可設定恆速運轉之切割機，尤其是指利用一人機介面設定一恆速轉速來控制馬達之轉速，並且在該人機介面顯示該馬達之運轉轉速以及運轉功率或者其他的運轉資訊。This creation is about a cutting machine that can set a constant speed operation, especially when a constant speed is set by a human machine interface to control the rotation speed of the motor, and the operating speed and operating power of the motor or other are displayed on the human machine interface. Operational information.
目前市面上之切割機，皆使用有刷馬達來做為切割機的驅動馬達，而有刷馬達具有體積過大、重量重，而導致切割機無法隨身攜帶等問題，且有刷馬達無法輕易地改變轉速來切割，若要調整有刷馬達的轉速來進行切割，需外接一個利用控制電流量的方式的調速裝置才能進行調整有刷馬達之轉速，據此，有刷馬達會造成生產時，配裝上的規劃問題。At present, the cutting machine on the market uses a brush motor as the driving motor of the cutting machine, and the brush motor has the problem of excessive volume and heavy weight, which causes the cutting machine to be carried around, and the brush motor cannot be easily changed. Rotating speed to cut, if you want to adjust the speed of the brush motor to cut, you need to connect a speed control device with the control current amount to adjust the speed of the brush motor. According to this, the brush motor will cause production. Planning problems with loading.
再者，上述之固定轉速或者是調整後的轉速，皆為空載時的轉速，每當切割機進行切割時，馬達必然會受到待切材料的阻力影響，此時馬達之運轉轉速(負載轉速)必然下降，造成切割的效率不佳，更導致可能無法切斷材料，而市面上的可攜帶式切割機皆無安裝資訊輸出介面提供運轉資訊，讓使用者通常只能藉著自身的經驗控制驅動手把下壓的力道或鋸片的速度，來增加切割的流暢度進行切割，而無經驗之使用者既無法藉自身經驗來控制力度，更無法順暢地切斷待切材料，而上述兩使用者之操作，也都不易判斷該切割時的力度，造成操作上的困難。Furthermore, the above fixed rotational speed or the adjusted rotational speed is the rotational speed at no load. When the cutting machine performs cutting, the motor is inevitably affected by the resistance of the material to be cut, and the operating speed of the motor (load speed) ) Inevitably, the efficiency of cutting is not good, and the material may not be cut off. The portable cutting machine on the market does not have an information output interface to provide operational information, so that the user can usually control the driving by his own experience. The hand presses the force of the force or the speed of the saw blade to increase the smoothness of the cutting for cutting, and the inexperienced user can neither control the strength by his own experience, nor can it smoothly cut off the material to be cut, and the above two uses The operation of the person is also difficult to judge the strength of the cutting, resulting in operational difficulties.
另外，在切割時，因使用者不知切割機操作是否已達額定輸出功率，若達額定輸出功率，使用者仍持續操作時，恐造成馬達的燒毀。In addition, during cutting, the user does not know whether the cutting machine has reached the rated output power. If the rated output power is reached and the user continues to operate, the motor may be burnt.
據此，本創作希望提供一種能夠克服上述缺點的可設定恆速運轉之切割機。Accordingly, the present invention contemplates providing a cutter capable of setting a constant speed operation that overcomes the above disadvantages.

本創作的次要目的為利用一補償電流，提供額外的功率於因受到待切材料的阻力影響而下降的負載轉速，其方法是先經由控制模組預先輸入一恆速轉速設定值，該控制模組會計算因阻力影響而下降的轉速還需增加多少的轉速之功率，輸出對應之補償功率到馬達，該馬達因補償功率的添加，使負載轉速能保持一樣於空載轉速，使切割時能保持一定切割力道。The secondary purpose of this creation is to use a compensation current to provide additional power to the load speed that is reduced by the resistance of the material to be cut. The method is to first input a constant speed speed setting value through the control module. The module calculates the power of the speed that needs to be increased by the speed of the resistance, and outputs the corresponding compensation power to the motor. The motor is added with the compensation power so that the load speed can be kept the same as the idle speed. Can maintain a certain cutting force.

當進行切割時，依據驅動手把200所界定之方向，使用者下壓驅動手把200進而帶動側邊之鋸片30位移至待切割物之位置，進行切割，此時因受到待切割物之切割時阻力的影響，該馬達40之轉速必然會減少(以下因阻力影響而下降之轉速都簡稱為:負載轉速)，例如從1300rpm大幅下降至1000rpm等，進而造成切割效率的不良，依據步驟S13，此時檢測單元62會檢測該負載轉速下馬達40運轉的電流與電壓，並產生一電流信號與一電壓信號於該微處理單元61，依據步驟14或步驟S17，該微處理單元61根據該電壓信號與該電流信號，計算馬達40即時的運轉轉速或運轉功率。When the cutting is performed, according to the direction defined by the driving handle 200, the user presses the driving handle 200 to drive the side saw blade 30 to the position of the object to be cut, and performs cutting, at which time the object to be cut is received. The influence of the resistance during cutting, the rotational speed of the motor 40 is inevitably reduced (hereinafter, the rotational speed decreased due to the influence of the resistance is simply referred to as: the load rotational speed), for example, from 1300 rpm to 1000 rpm, and the cutting efficiency is poor, according to step S13. At this time, the detecting unit 62 detects the current and voltage of the motor 40 under the load rotation speed, and generates a current signal and a voltage signal to the micro processing unit 61. According to step 14 or step S17, the micro processing unit 61 according to the step The voltage signal and the current signal calculate the instantaneous operating speed or operating power of the motor 40.
在本創作之較佳實施例中，該馬達40採用無霍爾無刷直流電馬達，透過微處理單元61控制驅動單元63的佔空比來控制該馬達40之恆速轉速，例如： 基於該馬達40之100%的額定功率，該微處理單元61控制該驅動單元63只使用約60%的功率來驅動馬達40運轉在設定的恆速轉速，當該馬達40切割時遇到阻力使轉速減少時，該微處理單元61會控制該驅動單元63將其餘的40%功率補上，使該馬達40在遇到阻力的情況下，能夠保持運轉轉速為所輸入之恆速轉速值。當切割硬度較大或者厚度較大的材質時，為了維持該馬達40之恆速轉速，該微處理單元61會控制驅動單元63，進而加大維持恆速之補償功率。In the preferred embodiment of the present invention, the motor 40 employs a Hallless brushless DC motor, and the duty ratio of the drive unit 63 is controlled by the microprocessor unit 61 to control the constant speed of the motor 40, for example: based on the motor 40% of the rated power of 40, the microprocessor unit 61 controls the drive unit 63 to use only about 60% of the power to drive the motor 40 to operate at a set constant speed, and when the motor 40 is cut, the resistance is reduced to reduce the speed. The microprocessor unit 61 controls the drive unit 63 to compensate for the remaining 40% of the power, so that the motor 40 can maintain the operating speed as the input constant speed value when the resistance is encountered. When cutting a material having a large hardness or a large thickness, in order to maintain the constant speed of the motor 40, the microprocessor unit 61 controls the driving unit 63 to increase the compensation power for maintaining the constant speed.

The preferred embodiment of the present invention is that the human interface 50 is disposed on the driving handle 200 so that the display angles of the human interface 50 of the two setting positions are convenient for the user. The user can obtain the instant information when the cutting machine performs cutting to improve the efficiency of cutting. The setting position of the human machine interface 50 is not limited to the driving handle 200, for example, is set on the base. 10. The position of the motor 40 and the saw blade 30 can be set by the user at the same angle as the information of the cutting machine can be obtained.
總體而言，本創作之可設定恆速運轉之切割機主要是提供該人機介面50，讓使用者能調整恆速轉速，進而達到節能之目的，以及在切割時能獲得切割機即時的資訊，判斷是否設定或操作上有誤，進而使該切割機的壽命提升，更可方便的進行切割上的操作。In general, the cutting machine that can set the constant speed operation mainly provides the human-machine interface 50, so that the user can adjust the constant-speed rotation speed, thereby achieving the purpose of energy saving, and obtaining the instant information of the cutting machine during cutting. It is judged whether the setting or the operation is wrong, thereby improving the life of the cutting machine, and the cutting operation can be conveniently performed.
