New description: [New technical field] This creative department has an improved structure for turning tools, especially for the design of c-tools, which is used for the turning of workpieces. The lathe is in compliance with the [prior art]. Therefore, the turning tool can process a good turning tool with respect to the lathe to be able to withstand high cutting capacity.
所钟「工欲善其事，必先利其器」， 切削工件，實在佔有舉足輕重之地位， 速切削，而且耐操能夠有極佳的車削進 刀。 而就目前市面販減車刀而言，如果來做大進刀量且高 .速切削金屬工件，則實在乏善可陳，導致在切·件時，通常^ ^幾段賴職，且車難度也無法義最佳絲，判車刀不 疋頓刀’就疋裂刀，甚至整個車削製程中要頻頻更換刀具， • 才能解決較難解之車削工件。 、 所以财f絲刀，絲因為這樣導致生產效能低落，且車 刀耗損率極高，反而增加車床加工業者之成本負擔。 【新型内容】 本創作車刀之改良結構，主要是在車刀架前端一體延製有 一弧形部，並於弧形部之上方製設有一定位槽，藉由定 位槽可供車刀片嵌設定位，又在定位槽處製設有一深 孔，藉由深孔使能提供一定位銷迫入定位，俾當將車刀 M336095 片置入於定位槽，使車刀片後端與定位銷成抵靠，再配 合螺栓及壓制片將車刀片鎖固，而達到最佳定位精度效 果。 本創作車刀之改良結構，再由於定位槽與車刀片的配合 底面，都經研磨加工，使能達到支撐平穩及精度高的優 點，當在咼速車削端面具有深度的工件時，還能夠以大 進刀篁及南速切削工件，除了可增加加工精確度之品質 提昇，更能大大提昇生產效能。 【實施方式】 請參閱第一圖、第二圖、第三圖所示，本創作車刀之改良結 構，主要係於車刀架1之預定處製設有一螺紋孔i丄，使 能配合一螺栓1 2及一壓制片1 3，可以將車刀片2鎖 固定位，主要是在車刀架1前端一體延製有一弧形部工 4，並於弧形部1 4之上方製設有一定位槽1 4 1，該 ® 定位槽1 4 1概製成V狀，使可以供車刀片2之底面成 等狀嵌設定位，又在定位槽1 4 1處製設有一深孔工4 2 ’係與定位槽141成垂直交錯，藉由深孔1 4 2， 使能提供一定位銷3迫入成緊配合定位，俾當將車刀片 2置入於定位槽1 4 1，使車刀片2後端與定位銷3成 抵靠，再配合螺栓1 2及壓制片1 3將車刀片2鎖固定 位（如第四圖所示）’這樣就能得到最佳定位精度；再者， 由於定位槽1 4 1與車刀片2的配合底面，都經研磨加 M336095 工，使能達到支撐平穩及精度高的優點。 最後，請再配合第五圖所示，藉由本創作之設計改 良，當在高速車削端面具有深度的工件w時，就算是以 大進刀量及高速切削，都能發揮極致的車削效益，除了 增加加工精確度品質提昇，更能大大提昇生產效能及降 低成本。 綜合以上結構及實施說明，本創作可達到增進定位精度，且 使加工過程能達到平穩及精密度高之效益。 【圖式簡單說明】 第一圖係本創作之立體分解圖。 第二圖係本創作之立體組合外觀圖。 第三圖係本創作另一角度之立體組合外觀圖。 第四圖係本創作之局部剖視圖。 第五圖係本創作運用於車削時之實施例圖。 【主要元件符號說明】 1 車刀架 12螺栓 14 弧形部 1 4 2 深孔 3 定位銷 11 螺紋孔 13 壓制片 141 定位槽 2 車刀片 W 工件The clock "has to be good at the job, must first sharpen its tools", cutting the workpiece, it has a very important position, fast cutting, and can withstand excellent turning. As far as the current market-reducing tools are concerned, if you want to make a large amount of cutting and high-speed cutting of metal parts, it is really lacking, which leads to the fact that when cutting pieces, it usually takes a few paragraphs, and the difficulty of the car cannot be determined. The best wire, the knife is not a knife, it is a splitting knife, and even the tool must be changed frequently during the entire turning process. • It is difficult to solve the difficult workpiece. Therefore, because of this, the production efficiency is low, and the tool wear rate is extremely high, which in turn increases the cost burden of the lathe industry. [New content] The improved structure of the original turning tool is mainly to extend an arc-shaped portion at the front end of the tool holder, and a positioning groove is formed above the curved portion, and the positioning groove can be used for setting the car blade. A deep hole is formed in the positioning groove, and a positioning pin is forced to be positioned by the deep hole. When the turning tool M336095 is placed in the positioning groove, the rear end of the blade is offset from the positioning pin. Relying on the bolts and pressing sheets to lock the blade to achieve the best positioning accuracy. The improved structure of the original turning tool is further polished by the matching bottom surface of the positioning groove and the blade, so that the advantages of stable support and high precision can be achieved. When the workpiece is deep in the end face of the idle turning, the In addition to the increase in machining accuracy, the large-entry knives and the south-speed cutting workpieces can greatly improve production efficiency. [Embodiment] Please refer to the first figure, the second figure, and the third figure. The improved structure of the original turning tool is mainly provided with a threaded hole i丄 at the predetermined position of the tool holder 1, so that one can be matched. The bolt 1 2 and a pressing piece 13 can lock the blade 2 in a fixed position, mainly an arc-shaped part 4 is integrally formed at the front end of the tool holder 1, and a positioning is formed above the curved portion 14 The groove 1 4 1, the positioning groove 1 4 1 is formed into a V shape, so that the bottom surface of the blade 2 can be set in an equal shape, and a deep hole 4 2 ' is formed at the positioning groove 1 4 1 And the positioning slot 141 is vertically staggered, and the deep hole 14 2 enables the positioning pin 3 to be forced into the tight positioning position, and the car blade 2 is placed in the positioning slot 1 4 1 to make the blade 2 The rear end abuts against the positioning pin 3, and then the bolt 1 2 and the pressing piece 13 are used to lock the turning blade 2 (as shown in the fourth figure), so that the positioning accuracy can be obtained; further, due to the positioning The matching bottom surface of the groove 1 4 1 and the blade 2 is ground and added with M336095, so that the advantages of stable support and high precision can be achieved. Finally, please cooperate with the fifth figure. With the design improvement of this creation, when there is a deep workpiece w on the high-speed turning end face, even with large feed and high-speed cutting, the ultimate turning benefit can be achieved. Increase processing accuracy and quality, and greatly improve production efficiency and reduce costs. Based on the above structure and implementation description, this creation can achieve the advantages of improved positioning accuracy and high stability and precision in the processing.
