Description
本發明係有關一種工具機的防塵結構，尤指一種於工具機運轉時於工具機內部產生氣流而達到防塵效果的工具機的防塵結構。 The invention relates to a dustproof structure of a machine tool, in particular to a dustproof structure of a machine tool which generates airflow inside the machine tool when the machine tool is running to achieve a dustproof effect.
自從電動馬達的發明開始，幾世紀以來不斷的進步與發展為人類帶來生活上極大的便利，由最初工業用途的大型電動馬達，至今已應用於日常生活用品、工具機等小型電動馬達。 Since the invention of electric motors, continuous progress and development over the centuries have brought great convenience to human life. Large electric motors, originally used for industrial purposes, have been used in small electric motors such as daily necessities and machine tools.
目前業界常見的工具機，如研磨機等，主要都是透過馬達驅動而運轉，且在運轉時容易產生塵屑而影響工件或環境的清潔，因此，現在市面上的工具機多半都增設有吸塵裝置，用來清除工具機加工時所產生的塵屑。如中華民國第M245007號專利案所示，其揭露一種氣動式研磨機的排氣裝置，主要包括有一本體，該本體周面側向形成上下並排的一上延伸部及一下延伸部，該上延伸部設有進氣通孔，並於該進氣通孔設置一進氣接管，而該下延伸部於下方設有一集塵罩，且於集塵罩的開口處設有一研磨盤，且該研磨盤設有吸塵孔，並於該下延伸部側邊設有一連接集塵袋的集塵管，當該進器接管導入氣體使該研磨機運轉時，該研磨盤在進行研磨工作所產生的塵埃可經由該研磨盤上的吸塵孔引入，並通過該集塵罩進入該本體的下延伸部，再經由集塵管而導入該集塵管末端所套設的集塵袋中。 At present, the common machine tools in the industry, such as grinding machines, are mainly driven by the motor, and are easy to generate dust during operation, which affects the cleaning of the workpiece or the environment. Therefore, most of the machine tools on the market now have vacuuming. The device is used to remove dust generated when the tool is machined. As shown in the Patent No. M245007 of the Republic of China, it discloses a venting device for a pneumatic grinder, which mainly comprises a body, the peripheral surface of the body is laterally formed with an upper extending portion and a lower extending portion which are arranged side by side, and the upper extending portion The portion is provided with an intake through hole, and an intake pipe is disposed in the intake through hole, and the lower extension portion is provided with a dust collecting cover below, and an abrasive disk is disposed at the opening of the dust collecting cover, and the grinding is performed The disc is provided with a dust collecting hole, and a dust collecting pipe connecting the dust collecting bag is arranged on the side of the lower extending portion, and the dust generated by the grinding work is performed when the grinder is introduced into the gas to make the grinder operate. The dust collecting hole is introduced through the dust collecting hole, and enters the lower extending portion of the body through the dust collecting cover, and is introduced into the dust collecting bag which is disposed at the end of the dust collecting pipe through the dust collecting pipe.
另外，又如中華民國第517618號專利案所示，其揭露一種氣動式研磨機之排氣結構，係設有一具備吸塵孔之磨輪，而在磨輪上端置設一防塵罩，該防塵罩係與馬達殼體固接，而在馬達殼體之殼室內係容設一可動葉片氣壓馬達組，而在於馬達殼體一側並一體延設相鄰之進氣管及出氣管，而在進出氣管上並分別容設一進氣閥門組及一排氣消音組，同時在於進出氣管上並設可容設節流閥及調整鈕之容室，同時在於頂面一體延設對置之兩翼部，可固設一可活動之進氣板機；其中，該防塵罩內係延設一可樞接馬達殼體之排氣管之容槽，並容槽係延設至防塵罩連管部處，而在於馬達殼體排氣管內係設一概呈為L狀之導管，並導管下端係設一導流板片，藉使可動葉片氣壓馬達組之風力係向上由出風孔排出，而該導管下端係延伸至近防塵罩連管部出口前端，而使馬達之排氣可與防塵罩連管部之出口處形成一匯流處，而令研磨後之塵屑可因較大之出風而被快速吸除，而在馬達殼體排氣管與出氣管鄰接處係容設一調整鈕，該調整鈕具有一鏤空部及一牆部，而能操控出氣路徑，並可選擇係由出氣管排氣或由排氣管排氣。 In addition, as shown in the Patent No. 517618 of the Republic of China, it discloses a venting structure of a pneumatic grinding machine, which is provided with a grinding wheel having a dust collecting hole, and a dust cover is arranged at the upper end of the grinding wheel, and the dust cover is The motor casing is fixed, and a movable vane air motor unit is accommodated in the casing of the motor casing, and the adjacent intake pipe and the air outlet pipe are integrally extended on one side of the motor casing, and are in and out of the air pipe. And respectively, an intake valve group and an exhaust muffler group are arranged, and at the same time, a chamber for accommodating the throttle valve and the adjustment button is arranged on the inlet and outlet air pipes, and at the same time, the opposite wings are integrally extended on the top surface, Fixing a movable air intake plate machine; wherein the dust cover is provided with a cavity for the exhaust pipe of the pivotable motor casing, and the groove is extended to the dust cover pipe joint portion, and An L-shaped duct is disposed in the exhaust pipe of the motor casing, and a deflector plate is disposed at a lower end of the duct, so that the wind power of the movable vane air motor group is discharged upward from the air outlet hole, and the lower end of the duct Extending to the front end of the outlet of the dust cover connecting pipe, and making the motor The exhaust gas can form a confluence with the outlet of the dust cover connecting portion, so that the dust after grinding can be quickly sucked out by the larger air outlet, and the exhaust pipe of the motor casing is adjacent to the air outlet pipe. The system is provided with an adjustment button having a hollow portion and a wall portion, and can control the air outlet path, and can be selectively exhausted by the air outlet pipe or exhausted by the exhaust pipe.
由上述的專利案可知，目前工具機清除塵屑的方式，都是在工具機側邊裝設集塵管，使工具機運轉時，可同時進行吸塵工作。然而，加工所產生的塵屑係經由研磨盤與集塵罩向上進入工具機內部，再受吸塵的氣流方向影響而導入集塵管，由於塵屑行進的路徑並非封閉的通道，當塵屑向上進入該工具機內部時，無法確保所有塵屑都會被吸引至集塵管，況且，工具機的馬達、汽缸運轉時也會造成氣流，導致塵屑向上進入該工具機內部時，卻容易堆積在研磨機的各個縫隙之中，甚至會逸入帶動研磨盤高速旋轉的 汽缸內部，造成工具機內部零件的損壞。 It can be seen from the above patents that the current way of removing dust by the machine tool is to install a dust collecting pipe on the side of the machine tool, so that when the machine tool is running, the dust collecting work can be performed at the same time. However, the dust generated by the processing enters the inside of the machine tool through the grinding disc and the dust collecting hood, and is then introduced into the dust collecting tube by the direction of the air flow of the dust collecting. Since the path of the dust traveling is not a closed passage, when the dust is upward When entering the inside of the machine tool, it is impossible to ensure that all the dust will be attracted to the dust collecting pipe. Moreover, the motor and the cylinder of the machine tool will also cause airflow when running, which will cause the dust to accumulate when it enters the inside of the machine tool. Among the various gaps in the grinder, even the high-speed rotation of the grinding disc can be driven. Inside the cylinder, causing damage to internal parts of the machine tool.
本發明的主要目的，在於解決上述之缺失，使工具機運轉時可隔絕塵屑進入工具機內部，避免工具機在排塵的同時，外部塵屑隨氣流被吸入工具機而造成工具機損壞。 The main object of the present invention is to solve the above-mentioned defects, so that the dust can enter the inside of the machine tool when the machine tool is running, and the external dust is prevented from being sucked into the machine tool and the machine tool is damaged while the machine tool is being exhausted.
為達上述目的，本發明提出一種工具機的防塵結構，其主要具備有一工具機，其中，該工具機內部具有一容置空間以設置一工具軸與一導流件，該容置空間並設有一進氣區段與一連通該進氣區段的排氣區段，而該工具機設有連通該進氣區段的進氣口，以及連通該排氣區段的排氣口，且該工具軸於該排氣口外部接設一作動件，當該工具軸連動該作動件運轉時，該導流件由該進氣口引導外部氣體至該進氣區段，且將氣體引導至該排氣區段，而朝設置於該排氣口外部的作動件排出。 In order to achieve the above object, the present invention provides a dustproof structure of a machine tool, which is mainly provided with a machine tool, wherein the tool machine has an accommodating space therein for arranging a tool shaft and a flow guiding member, and the accommodating space is arranged An intake section and an exhaust section communicating with the intake section, and the machine tool is provided with an intake port communicating with the intake section, and an exhaust port communicating with the exhaust section, and the The tool shaft is connected with an actuating member outside the exhaust port. When the tool shaft is linked to the actuating member, the flow guiding member guides external air to the intake portion by the air inlet, and guides the gas to the The exhaust section is discharged toward an actuator disposed outside the exhaust port.
由於本發明所揭示的工具機係由內部朝該排氣口的作動件向外排出氣體，使該作動件加工時所產生的塵屑無法由該排氣口進入該工具機，不但可保持工具機內部的清潔，更可避免工具機內部的零件受塵屑的影響而損壞，藉此提高工具機的使用壽命。 Since the machine tool disclosed in the present invention discharges gas outward from the actuating member of the exhaust port, the dust generated during the processing of the actuating member cannot enter the machine tool through the exhaust port, and the tool can be maintained. The internal cleaning of the machine can prevent the internal parts of the machine tool from being damaged by the dust, thereby improving the service life of the machine tool.

The inside of the power tool 10 has an accommodating space 11 , and the accommodating space 11 is provided with an air intake section 111 and an exhaust section 112 communicating with the air intake section 111 , and the power tool 10 is surrounded by the side wall. The plurality of air inlets 12 are connected to the air intake section 111, and the air outlets 13 are connected to the exhaust section 112. The power tool 10 is provided with a tool shaft 20 in the accommodating space 11. The tool shaft 20 is driven by a driving device (not shown) such as a motor, a rotor, a stator, etc., to generate a rotational stroke relative to the power tool 10, and the tool shaft 20 is provided with a weight body 21, and the weight body 21 is provided. a first weight portion 211 and a second weight portion 212 are disposed in an overlapping manner, and the first weight portion 211 and the side portion of the second weight portion 212 are outwardly extended to protrude. The tool shaft 20 is eccentrically rotated by the first weight portion 211 and the second weight portion 212, and the weight body 21 is provided a flow guide 30 is a fan disposed on the weight body 21, and has a first blade portion 31 disposed on the first weight portion 211, and a second weight portion disposed on the second weight portion The second blade portion 32 of the portion 212 and a connecting portion 33 connecting the first blade portion 31 and the second blade portion 32 constitute the main structure of the present invention.
請參閱「圖4」所示，本發明的工具機10可為透過該工具軸20產生偏心轉動的任何機具，如圖中所示，該工具機10的工具軸20於該排氣口13外部接設一可對工件加工之作動件40，例如研磨盤，且該作動件40透過一設於該配重體21內的軸承22而與該配重體21相接，當工具機10啟動時，在該工具軸20帶動該配重體21運轉的同時，該導流件30同步受該工具軸20帶動而轉動，由於該進氣口 12與該第一扇葉部31的高度相當，該導流件30轉動時，該第一扇葉部31將由該進氣口12吸入外部氣體至該進氣區段111，該第一扇葉部31所吸入的氣體將先傳導第一配重部211以帶走第一配重部211產生的熱量，然後，氣體再被引導至該排氣區段112，而傳導至位於第一扇葉部31下方的第二扇葉部32，並由該第二扇葉部32傳導至第二配重部212而對第二配重部212進行散熱，最後，再朝設置於該排氣口13外部的作動件40排出；如此一來，除了可將該配重體21運轉所產生的高溫排出之外，再者，由於氣體經該排氣口13朝該作動件40排出，因此，該作動件40作動時產生的塵屑無法由該排氣口13向上侵入該工具機10，避免最靠近該排氣口13的軸承22(即設置於配重體21的軸承22)受塵屑影響而損壞，甚至可防止該工具軸20上方的機件，如轉子、軸承等，遭吹入的塵屑磨損，以確保工具機10能正常運作，並增加該工具機10的使用壽命。 Referring to FIG. 4, the machine tool 10 of the present invention can be any implement that generates eccentric rotation through the tool shaft 20. As shown in the figure, the tool shaft 20 of the power tool 10 is outside the exhaust port 13. An actuating member 40 for machining the workpiece, such as a grinding disc, is attached, and the actuating member 40 is coupled to the weight body 21 through a bearing 22 disposed in the weight body 21 when the machine tool 10 is started. While the tool shaft 20 drives the weight body 21 to operate, the flow guiding member 30 is synchronously rotated by the tool shaft 20, due to the air inlet. 12 is equivalent to the height of the first blade portion 31. When the flow guiding member 30 rotates, the first blade portion 31 will suck external air into the intake portion 111 from the air inlet 12, the first blade The gas sucked by the portion 31 will first conduct the first weight portion 211 to carry away the heat generated by the first weight portion 211, and then the gas is again guided to the exhaust portion 112 and conducted to the first blade. The second blade portion 32 below the portion 31 is transmitted from the second blade portion 32 to the second weight portion 212 to dissipate heat to the second weight portion 212, and finally, to the exhaust port 13 The external actuator 40 is discharged; in this case, in addition to the high temperature generated by the operation of the weight body 21, further, since the gas is discharged to the actuator 40 through the exhaust port 13, the operation is performed. The dust generated when the member 40 is actuated cannot be intruded into the machine tool 10 from the exhaust port 13 to prevent the bearing 22 closest to the exhaust port 13 (i.e., the bearing 22 disposed on the weight body 21) from being affected by dust. Damage, even prevent the parts above the tool shaft 20, such as rotors, bearings, etc., from being blown into the dust to ensure the machine tool 10 can operate normally and increase the service life of the machine tool 10.
綜上所述，本發明所揭示的工具機10主要於內部形成一設置工具軸20的容置空間11，該容置空間11設有一進氣區段111與一連通該進氣區段111的排氣區段112，且該工具機10於設有連通該進氣區段111的進氣口12，以及一端連通該排氣區段112的排氣口13，該工具軸20於該排氣口13外部接設一作動件40，此外，該工具機10更於該容置空間11設有一導流件30，藉該導流件30於該工具軸20運轉時，由該進氣口12引導外部氣體至該進氣區段111，並引導至該排氣區段112，且朝設置於該排氣口13的作動件40排出，藉此防止該工具機10運轉時，該作動件40於加工所產生的塵屑由該排氣口13向上侵入該工具機10，使該工具機10內部的零件不會 因塵屑而受損，以確保該工具機10可穩定運作，並可增加工具機10的使用壽命。 In summary, the machine tool 10 of the present invention mainly forms an accommodating space 11 for the tool shaft 20, and the accommodating space 11 is provided with an air inlet section 111 and a connecting air inlet section 111. An exhaust section 112, and the machine tool 10 is provided with an intake port 12 that communicates with the intake section 111, and an exhaust port 13 that communicates with the exhaust section 112 at one end, the tool shaft 20 is at the exhaust An actuating member 40 is connected to the outside of the port 13 . In addition, the power tool 10 is further provided with a flow guiding member 30 in the accommodating space 11 , and the air inlet 12 is operated by the flow guiding member 30 when the tool shaft 20 is operated. The external air is guided to the intake section 111 and guided to the exhaust section 112, and discharged toward the actuator 40 disposed at the exhaust port 13, thereby preventing the operating device 40 from operating when the machine tool 10 is in operation. The dust generated in the machining is intruded into the machine tool 10 from the exhaust port 13 so that the components inside the machine tool 10 are not Damaged by dust to ensure stable operation of the machine tool 10 and increase the service life of the machine tool 10.
