Description
本發明是有關於一種飛輪，特別是指一種利用轉動時的磨擦接觸傳遞動力的電動釘槍的飛輪。The present invention relates to a flywheel, and more particularly to a flywheel for an electric nail gun that transmits power using frictional contact during rotation.
以美國專利第6971567號案，及中華民國專利第96128582號案、96128577號案、96146438號案的飛輪為例，主要是在轉動過程中，利用離合作用及磨擦接觸的方式，拋甩一滑塊達到擊釘的目的。For example, in the case of U.S. Patent No. 6,971,567, and the flywheel of the Republic of China Patent No. 96128582, No. 96128577, and No. 96146438, the main purpose is to use a mechanism of separation and friction to throw a slider during the rotation process. Achieve the purpose of nailing.
值得一提的是，前述飛輪為了符合結構強度與轉動慣量的需求，一般都是以鐵材料製成，且該滑塊為了達到快速移動的目的，一般都是以鋁材料製成。It is worth mentioning that the flywheel is generally made of iron material in order to meet the requirements of structural strength and moment of inertia, and the slider is generally made of aluminum material for the purpose of rapid movement.
惟，在操作電動釘槍的過程中，動力源(如馬達)必須以最快的速度帶動該飛輪達到預定的轉數，才能有效的進行擊釘動作，因此，若該飛輪過重，除了會增加動力源(如馬達)的負載，延遲每次循環擊釘的時間，且該滑塊與該飛輪的材料硬度差異過大，容易造成該滑塊與該飛輪其中之一磨損，影響擊釘功能，及使用壽命。However, in the process of operating the electric nail gun, the power source (such as the motor) must drive the flywheel to a predetermined number of revolutions at the fastest speed to effectively perform the nailing action. Therefore, if the flywheel is too heavy, it will increase. The load of the power source (such as a motor) delays the time of nailing per cycle, and the difference in material hardness between the slider and the flywheel is too large, which easily causes wear of one of the slider and the flywheel, affecting the function of the nailing, and Service life.
因此，本發明之目的，即在提供一種能提升轉動效率，及延長使用壽命的電動釘槍的飛輪。Accordingly, it is an object of the present invention to provide a flywheel for an electric nail gun that can improve rotational efficiency and extend service life.
於是，本發明電動釘槍的飛輪，包含一內層，及一外層。該外層環固在該內層一外周面，且材料密度大於該內層。Thus, the flywheel of the electric nail gun of the present invention comprises an inner layer and an outer layer. The outer layer is secured to an outer peripheral surface of the inner layer and has a material density greater than the inner layer.
本發明的功效是以符合硬度需求及轉動慣量需求的外層，配合質輕且符合強度需求的內層，減少整體的重量，進而能提升該飛輪的轉動效率，以較高的轉動慣量提升擊發時的動能。The function of the invention is to meet the requirements of hardness requirement and moment of inertia, and to match the inner layer which is light in weight and meets the strength requirement, thereby reducing the overall weight, thereby improving the rotation efficiency of the flywheel and increasing the firing moment with a higher moment of inertia. Kinetic energy.
有關本發明之前述及其他技術內容、特點與功效，在以下配合參考圖式之一個較佳實施例的詳細說明中，將可清楚的呈現。The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.
參閱圖1、圖2，本發明電動釘槍的飛輪1的一較佳實施例用於驅動一衝擊塊2。該衝擊塊2是以鋁材料製成。該飛輪1包含一內層11，及一外層12。Referring to Figures 1 and 2, a preferred embodiment of the flywheel 1 of the electric nail gun of the present invention is used to drive a hammer block 2. The impact block 2 is made of an aluminum material. The flywheel 1 includes an inner layer 11 and an outer layer 12.
該內層11在本較佳實施例是以鋁材料或鎂材料其中一種製成。The inner layer 11 is made of one of an aluminum material or a magnesium material in the preferred embodiment.
該外層12環固在該內層11一外周面，其材料密度大於該內層11而界於1.5~3.5kg/mm3 ，且硬度界於HRB50~90。在本較佳實施例中，該外層12是以銅材料製成，且可以透過表面處理提高硬度，或可以鑄鐵製成。The outer layer 12 is annularly fixed on an outer peripheral surface of the inner layer 11, and has a material density larger than the inner layer 11 and is 1.5 to 3.5 kg/mm 3 , and the hardness is limited to HRB 50 to 90. In the preferred embodiment, the outer layer 12 is made of a copper material and may be hardened by surface treatment or may be made of cast iron.
在該飛輪1轉動過程中，同樣是利用磨擦接觸的方式，以該外層12與該衝擊塊2磨擦接觸，進而拋甩該衝擊塊2達到擊釘的目的。During the rotation of the flywheel 1, the frictional contact is also used to frictionally contact the outer layer 12 with the impact block 2, thereby throwing the impact block 2 to achieve the purpose of nailing.
由於該飛輪1分解成內、外二層，因此，能以銅材料製成的外層12，符合硬度需求及轉動慣量需求，及以鋁材料或鎂材料製成的內層11，在符合強度需求的情形下，減少整體的重量，舉例來說，以全鐵材料製成且直徑66mm的飛輪而言，其重量約218g，轉動慣量為1.45×105 Kg.m2 ，達到預定轉速的時間約為0.15秒，而本發明以二種不同材料製成內、外層11、12的飛輪1，重量約175.6g，轉動慣量為1.34×105 Kg.m2 ，達到預定轉速的時間約為0.1秒。Since the flywheel 1 is decomposed into inner and outer layers, the outer layer 12 which can be made of copper material meets the hardness requirement and the moment of inertia demand, and the inner layer 11 made of aluminum material or magnesium material meets the strength requirement. In the case of the case, the overall weight is reduced. For example, a flywheel made of a full iron material and having a diameter of 66 mm has a weight of about 218 g and a moment of inertia of 1.45 × 10 5 Kg.m 2 , which is about a predetermined rotation speed. The flywheel 1 of the inner and outer layers 11, 12 of the present invention has a weight of about 175.6 g and a moment of inertia of 1.34 × 10 5 Kg.m 2 , and the time to reach the predetermined rotation speed is about 0.1 second. .
雖然本發明的轉動慣量因為整體重量減輕，而降低了8%，惟，本發明相較於習知的飛輪，仍然因為重量大幅減少了20%，而能以更短的時間，達到預設轉速，進而能提升該飛輪1的轉動效率，及提升擊發時的反應速度。Although the moment of inertia of the present invention is reduced by 8% due to the overall weight reduction, the present invention achieves a preset speed by a 20% reduction in weight compared to the conventional flywheel. In turn, the rotation efficiency of the flywheel 1 can be improved, and the reaction speed at the time of firing can be improved.
據上所述可知，本發明之電動釘槍的飛輪具有下列優點及功效：According to the above description, the flywheel of the electric nail gun of the present invention has the following advantages and effects:
1、本發明是以符合硬度需求及轉動慣量需求的外層12，配合質輕且符合強度需求的內層11，減少整體的重量，進而能提升該飛輪的轉動效率，以較高的轉動慣量提升擊發時的動能。1. The present invention is an outer layer 12 that meets the requirements of hardness and moment of inertia, and cooperates with the inner layer 11 which is light in weight and meets the strength requirement, thereby reducing the overall weight, thereby improving the rotation efficiency of the flywheel and increasing the rotational inertia. The kinetic energy when firing.
2、且由於銅材料與鋁材料在硬度上的差異，比銅材料與鐵材料或鋁材料與鐵材料的硬度差異小，因此，不管是銅材料製成的飛輪1外層12，或鋁材料製成的衝擊塊2，都不易磨損，而能提升使用壽命，及擊釘效果。2. Due to the difference in hardness between the copper material and the aluminum material, the difference in hardness between the copper material and the iron material or the aluminum material and the iron material is small, and therefore, whether it is the outer layer 12 of the flywheel 1 made of copper material, or made of aluminum material The impact block 2 is not easy to wear, but can improve the service life and the nailing effect.
惟以上所述者，僅為本發明之較佳實施例而已，當不能以此限定本發明實施之範圍，即大凡依本發明申請專利範圍及發明說明內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
