Description
本發明是有關於一種端銑刀鑽頭研磨機,特別是有關於可量測刀具偏心量之端銑刀鑽頭研磨機。 The present invention relates to an end mill bit grinder, and more particularly to an end mill bit grinder that can measure the eccentricity of a tool.
銑削為一種利用銑刀或鑽頭及銑床對工件進行加工的機械方法,藉此達成對物件的鑽孔、表面加工成形、台階、溝槽和切割等製程。 Milling is a mechanical method of machining a workpiece using a milling cutter or a drill bit and a milling machine to achieve drilling, surface forming, stepping, groove and cutting of the workpiece.
一般而言,在自動化銑削機床的加工過程中容易因機台因素或磨耗的影響,使銑刀或鑽頭產生偏心及傾斜等狀況,導致工件成品失去精度,狀況嚴重時甚至發生意外危險。如果銑刀或鑽頭變鈍或者刀頭與工作線角度偏移,則會使銑刀或鑽頭的壽命縮短。 In general, in the processing of automatic milling machine tools, it is easy to cause eccentricity and tilting of the milling cutter or the drill bit due to the influence of machine factors or wear, which leads to the loss of precision of the finished workpiece, and even an accidental danger when the condition is serious. If the milling cutter or bit becomes dull or the tip is offset from the working line, the life of the milling cutter or bit will be shortened.
故,為了得到良好的加工面並延長銑刀或鑽頭壽命,銑刀或鑽頭必須經常利用研磨機進行研磨。然而市面上所售之研磨機僅具有研磨之單一功用,使用者無法精確得知銑刀或鑽頭在研磨時的偏心量,研磨後之銑刀或鑽頭依然不精準而無法精確地工作。 Therefore, in order to obtain a good working surface and extend the life of the milling cutter or the drill, the milling cutter or the drill must always be ground using a grinder. However, the grinding machine sold on the market only has a single function of grinding, and the user cannot accurately know the eccentricity of the milling cutter or the drill bit during grinding. The milling cutter or the drill bit after grinding is still inaccurate and cannot work accurately.
因此,為求解決前述研磨機無法於研磨時同時量測偏心量的缺點。發明人積極投入時間並竭盡心思,完成一種 可同時量測偏心量之端銑刀鑽頭研磨機。 Therefore, in order to solve the disadvantage that the aforementioned grinder cannot measure the amount of eccentricity while grinding. The inventor actively invested time and tried his best to complete a kind of The end mill cutter bit grinder can measure the eccentricity at the same time.
本發明的目的在於提供一種可量測刀具偏心量之端銑刀鑽頭研磨機,而不需花費時間將銑刀或鑽頭等刀具由研磨機移至另一量測機台。 SUMMARY OF THE INVENTION It is an object of the present invention to provide an end mill bit grinder capable of measuring tool eccentricity without taking time to move a cutter such as a cutter or a drill from a grinder to another measuring machine.

As shown in FIG. 1 , the grinding tool bed 400 can be a grinding wheel, and for the material of the tool M to be ground, the grinding tool bed 400 must also be relatively selected for grinding, which is a conventional technique. Not detailed description.
同步雷射位移計500連接控制數位控制主軸300,同步雷射位移計500用以量測刀具M之偏心量O供數位控制主軸300調整刀具M。同步雷射位移計500包含一雷射二極體510及一光感測器520,雷射二極體510用以發出雷射光射於刀具M之表面。光感測器520用以感測雷射光射於刀具M表面之散射光且推估刀具M之偏心量O回傳至數位控制主軸300。其中光感測器520可以為一電荷耦合元件。此外,光感測器520也可為一互補式金氧半導體及一數位訊號處理單元。在第1圖之實施方式當中,同步雷射位移計500雖繪示為固定於底座200上,但其可改變為可拆卸式的結構而適配於不同的研磨機上。 The synchronous laser displacement meter 500 is connected to control the digital control spindle 300. The synchronous laser displacement meter 500 is used to measure the eccentricity O of the tool M for the digital control spindle 300 to adjust the tool M. The synchronous laser displacement meter 500 includes a laser diode 510 and a light sensor 520 for emitting laser light to the surface of the tool M. The light sensor 520 is configured to sense the scattered light of the laser light incident on the surface of the tool M and estimate that the eccentricity O of the tool M is transmitted back to the digital control spindle 300.

請參照第3圖,其係繪示前述端銑刀鑽頭研磨機之控制方法,其步驟包含:步驟710,利用同步雷射位移計量測刀具被研磨刀床施壓時之偏心量。以及步驟720,使數位控制主軸根據偏心量調整刀具。 Please refer to FIG. 3, which illustrates the control method of the end mill bit grinding machine. The method includes the following steps: Step 710: Measure the eccentricity of the tool when the tool is pressed by the grinding tool by using the synchronous laser displacement. And step 720, the digital control spindle adjusts the tool according to the eccentricity.
為了解釋第3圖,請一併同時參照第1圖、第2圖及第4圖,其中第4圖係繪示依照刀具之偏心量之量測示意圖。當研磨刀床400研磨刀具M而對刀具M施壓時,同時利用同步雷射位移計500之雷射二極體510射出雷射光L1 至刀具M表面,而光感測器520接收雷射光L1散射後之散射光L2後,計算得到偏心量O回傳至數位控制主軸300來調整刀具M之角度及位置,使刀具M之偏心量O為零。 In order to explain Fig. 3, please refer to Fig. 1, Fig. 2 and Fig. 4 at the same time, wherein Fig. 4 is a schematic diagram showing the measurement according to the eccentricity of the tool. When the grinding tool 400 grinds the tool M to apply pressure to the tool M, the laser diode L1 of the synchronous laser displacement meter 500 is simultaneously used to emit the laser light L1. After the light sensor 520 receives the scattered light L2 scattered by the laser light L1, the eccentric amount O is calculated and sent back to the digital control spindle 300 to adjust the angle and position of the tool M, so that the eccentricity of the tool M is O is zero.
藉此,利用同步雷射位移計決定數位控制主軸的作動,使端銑刀鑽頭研磨機在研磨刀具同時具有量測刀具偏心量之功能,提高刀具之研磨精度及其使用壽命。此外,同步雷射位移計可為可拆卸式的結構而設置於端銑刀鑽頭研磨機上,使任一種只具有研磨功能之研磨機也可同時具有量測偏心量之功能。 Thereby, the synchronous laser displacement meter is used to determine the operation of the digital control spindle, so that the end mill bit grinding machine has the function of measuring the tool eccentricity at the same time, thereby improving the grinding precision and the service life of the tool. In addition, the synchronous laser displacement meter can be disposed on the end mill bit grinder for the detachable structure, so that any grinder having only the grinding function can simultaneously have the function of measuring the eccentricity.
