Description
本發明有關一種防塵工具機，尤指一種可防止粉塵侵入工具機內部的防塵工具機。 The invention relates to a dustproof machine tool, in particular to a dustproof machine tool which can prevent dust from entering the inside of the machine tool.
工具機由於體積小、價錢較低，並且可連接不同的應用工具而形成多種變化型態，如研磨盤、砂輪機、鑽孔機、電動板手等多種型態，可協助作業人員快速執行某些工作程序而廣受歡迎，除了具有以電力驅動的電動工具之外，亦具有以壓力氣體驅動的氣動工具。 Due to its small size, low price, and the ability to connect different application tools, the machine tool can be used to form a variety of changes, such as grinding discs, grinders, drilling machines, electric wrenches, etc. These work procedures are very popular, in addition to electric power-driven power tools, they also have pneumatic tools driven by pressurized gas.
而工具機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。 However, when the machine tool is running, it is easy to generate dust and affect the cleaning of the workpiece or the environment. Therefore, most of the machine tools on the market now have a dust suction device for removing dust generated during the machining of the tool. 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. It can be introduced through the dust suction hole on the grinding disc, and enters the lower extension portion of the body through the dust collecting cover, and then introduces the dust collecting through the dust collecting tube. In the dust bag that is placed at the end of the tube.
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。上述集塵管僅能排除部分位置的塵屑，特別是工具機施工的位置，而一般工具機都是在握把上設置裝設孔，用以裝設按壓開關，當施力推動按壓開關後驅動工具機運作，但是工具機作業時產生的塵屑無所不在，極容易由按壓開關與裝設孔間的縫隙侵入工具機中，甚至會逸入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. The dust collecting pipe can only remove the dust in a part of the position, especially the position of the machine tool construction, and the general machine tool is provided with a mounting hole on the grip for installing the push switch, and driving when the pressing force pushes the push switch The machine tool works, but the dust generated during the operation of the machine tool is ubiquitous. It is easy to invade the machine tool by the gap between the push switch and the mounting hole, and even escape into the high-speed rotating cylinder, causing damage to the internal parts of the machine tool.

The lower side of the portion 121. In addition, the power tool 10 is pivotally provided with a control rod 14 on the handle portion 11 , and the control rod 14 is opposite to the grip portion 11 . A pivoting stroke is generated and the drive switch 20 is pressed during the pivoting stroke to operate the machine tool 10.
而該防塵套30係套設於該驅動開關20與該彈性件24的外圍，使該彈性件24位於該驅動開關20與該防塵套30之間，且該防塵套30一端具有套設該驅動開關20的開口31，該開口31周緣形成一壓抵部32以壓抵凸出該握把部11的擋牆122並包圍該通孔12，而該防塵套30另一端設有一穿設孔33，該穿設孔33係供該驅動開關20的穿設部22插入，且該穿設孔33周緣設有一抵制該第一抵靠部21的第二抵靠部34，使該驅動開關20的第一抵靠部21外露於該防塵套30，如是構成本發明的主要架構，使該工具機10在操作時，可防止塵屑由該驅動開關20與該通孔12侵入。 The dust jacket 30 is sleeved on the periphery of the driving switch 20 and the elastic member 24, so that the elastic member 24 is located between the driving switch 20 and the dust jacket 30, and the dust jacket 30 has a driving force at one end thereof. The opening 31 of the switch 20 has a pressing portion 32 formed on the periphery of the opening 31 to press against the retaining wall 122 protruding from the grip portion 11 and surrounding the through hole 12, and the other end of the boot 30 is provided with a through hole 33. The through hole 33 is inserted into the through portion 22 of the driving switch 20, and the peripheral edge of the through hole 33 is provided with a second abutting portion 34 that resists the first abutting portion 21, so that the driving switch 20 is The first abutting portion 21 is exposed to the dust jacket 30, and the main structure of the present invention is configured to prevent dust from entering the driving switch 20 and the through hole 12 during operation.
另外，請同時參閱「圖4-1至圖4-2」所示，該防塵套30具有間隔設置的凸出段35與凹陷段36，當該控制桿14樞轉下壓該驅動開關20時，該驅動開關20以該第一抵靠部21壓制該彈性件24以及該防塵套30的第二抵靠部34，使該彈性件24受該驅動開關20推動而壓縮，且該防塵套30受該驅動開關20推動後，可透過該凸出段35與該凹陷段36產生形變而一併產生壓縮，而該防塵套30更可採用撓性材質，如橡膠，不但可透過橡膠的材質達到密封、防塵的效果，更可藉由其撓性使該驅動開關20上下運動，而可省略彈性件24，不但可減少生產成本，更能節省組裝時間。 In addition, please refer to FIG. 4-1 to FIG. 4-2 at the same time, the dust jacket 30 has a protruding portion 35 and a recessed portion 36. When the control rod 14 pivots and presses the driving switch 20, The driving switch 20 presses the elastic member 24 and the second abutting portion 34 of the dust jacket 30 with the first abutting portion 21, so that the elastic member 24 is compressed by the driving switch 20, and the dust jacket 30 is compressed. After being driven by the driving switch 20, the protruding portion 35 and the concave portion 36 can be deformed to generate compression, and the dust jacket 30 can be made of a flexible material, such as rubber, which can be made of rubber. The sealing and dustproof effect can further move the driving switch 20 up and down by its flexibility, and the elastic member 24 can be omitted, which not only reduces the production cost, but also saves assembly time.
