Description

氣動工具機Pneumatic machine

本發明涉及一種氣動工具機，尤指一種工具頭上設有二樞接臂的氣動工具機。The invention relates to a pneumatic tool machine, in particular to a pneumatic tool machine with two pivotal arms on the tool head.

現有手持式的氣動工具機主要可被區分為工具頭以及握柄兩部件，手持式氣動工具機在工具頭內部設置氣動馬達，工具頭與握柄上形成進氣通道，外部氣體沿進氣通道流入工具頭內，以驅動氣動馬達運轉，藉此使氣動馬達帶動工具件工作。Existing hand-held pneumatic machine tools can be mainly divided into two parts: a tool head and a handle. The hand-held pneumatic machine tool is equipped with an air motor inside the tool head, and an air intake channel is formed on the tool head and the handle.

然而，習知手持式氣動工具機由於工具頭與握柄無法相對活動，使得氣動工具機容易受到作業環境的寬窄或是障礙物的限制，無法順利施工。在過去，作業人員僅能透過擺動其手腕角度，使工具件施工位置與待施工面符合，但此舉容易影響作業流暢度，同時也易造成作業人員的職業傷害。However, in the conventional hand-held pneumatic machine tool, because the tool head and the handle cannot move relative to each other, the pneumatic machine tool is easily limited by the width of the working environment or obstacles, and cannot be successfully constructed. In the past, the operator could only make the construction position of the tool part conform to the surface to be constructed by swinging the angle of his wrist, but this would easily affect the smoothness of the operation and also easily cause occupational injuries to the operator.

而氣動工具機製造商為解決前述問題，因此有了TW I711511、TW I724866以及TW I724856等專利。前述專利公開了工具頭與握柄之間透過樞軸連接，使用者透過操作樞軸改變工具頭與握柄之間的角度，令工具頭可以因應不同的作業需求相對握柄擺動。然而，TW I711511及TW I724866所揭的氣動工具機的工具頭採單點組裝，即在工具頭上設置一伸入握柄兩卡接臂之間的組裝頸部，由於工具頭內部設置有氣動馬達，且氣動工具機擬進行作業時氣動馬達還須與工具件連接，組裝頸部必須負起承載氣動馬達與工具件重量的責任，導致組裝頸部在久經使用後容易損壞。再者，習用氣體由主流道流向該頭部的過程中，氣流由主流道兵分二路進入支流道，於後再進入頭部中，惟此氣路設計容易影響氣流的集中程度，進而造成氣流流速下降，無法正常驅動馬達工作。此外，前述所揭的氣動工具機需透過大量額外的密封結構來建立氣路，導致組裝上不便，此外若密封結構喪失氣密功能時，容易造成習用氣動工具機內部的氣流流速過低，造成氣動工具機無法正常運作。And pneumatic machine tool manufacturers have patents such as TW I711511, TW I724866 and TW I724856 in order to solve the aforementioned problems. The aforementioned patent discloses that the tool head and the handle are connected through a pivot, and the user can change the angle between the tool head and the handle by operating the pivot, so that the tool head can swing relative to the handle according to different operation requirements. However, the tool head of the air tool machine disclosed by TW I711511 and TW I724866 adopts single-point assembly, that is, an assembly neck extending between the two clamping arms of the handle is arranged on the tool head. Since the tool head is provided with an air motor inside, and the air motor must be connected with the tool when the air tool is intended to work, the assembly neck must bear the responsibility of carrying the weight of the air motor and the tool, resulting in the assembly neck being easily damaged after long-term use. Furthermore, during the process of conventional gas flowing from the main channel to the head, the air flow from the main channel divides into two channels and enters the branch channel, and then enters the head. However, the design of the gas channel easily affects the concentration of the air flow, which in turn causes the flow rate of the air flow to drop, making it impossible to drive the motor normally. In addition, the aforementioned pneumatic tool requires a large number of additional sealing structures to establish an air circuit, which causes inconvenience in assembly. In addition, if the sealing structure loses its airtight function, the air flow rate inside the conventional pneumatic tool is likely to be too low, resulting in the malfunction of the pneumatic tool.

本發明的主要目的，在於解決習用工具頭可調整式氣動工具機結構不足所衍生的問題。The main purpose of the present invention is to solve the problems derived from the insufficient structure of conventional tool head adjustable pneumatic machine tools.

One end of the handle is a first pivot end. The handle has a main flow channel extending to the first pivot end and a switch set arranged on the main flow channel. The switch set determines whether the main flow channel is in a ventilation state or a ventilation stop state. The pivot arm serves as a second pivot end combined with the first pivot end through a pivot shaft, and the body forms a chamber for providing the tool driving group and at least one auxiliary channel communicating with the chamber and extending to the two pivot arms respectively. Wherein, the pivot has a transfer channel and two transfer ports that communicate with the transfer channel and make the main channel and the secondary channel form a ventilation path.

Furthermore, through the arrangement of the pivot shaft and the transfer channel of the present invention, the conventional problem that a large number of sealing structures must be used to establish a ventilation path can be improved.

本發明詳細說明及技術內容，茲配合圖式說明如下：The detailed description and technical content of the present invention are described as follows in conjunction with the drawings:

請參閱圖1，本發明提供一種氣動工具機100，該氣動工具機100搭配一工具件70使用，該氣動工具機100根據該工具件70的種類而可以是一氣動扳手、一氣動打磨機或是一氣鑽等。換句話來說，本發明所揭的該氣動工具機100不限定其功能型態。Referring to FIG. 1 , the present invention provides an air tool 100 , which is used with a tool 70 . The air tool 100 can be an air wrench, an air grinder, or an air drill according to the type of the tool 70 . In other words, the pneumatic machine tool 100 disclosed in the present invention does not limit its function type.

併請參閱圖2至圖6，該氣動工具機100具有一握柄10以及一工具頭30，該握柄10提供一使用者操作該氣動工具機100時握持，該握柄10的一端為一第一樞接端11，該握柄10具有一延伸至該第一樞接端11的主流道12，及一設於該主流道12上的開關組13，該主流道12連通該握柄10上的一進氣口14，該開關組13在受該使者操作後決定該主流道12的通氣狀態。其中，本文所述該主流道12的通氣狀態，指的是該開關組13在初始未操作時，該氣動工具機100不啟動，令該主流道12未被導通而無法向該工具頭30輸出氣體，或者是在該開關組13受操作時，該氣動工具機100啟動，令該主流道12被導通，以承接由該進氣口14而來的氣體並向該工具頭30輸出氣體，藉此令該氣動工具機100得以驅使該工具件70工作。2 to 6, the pneumatic machine tool 100 has a handle 10 and a tool head 30. The handle 10 is provided for a user to hold when operating the air tool machine 100. One end of the handle 10 is a first pivot end 11. The handle 10 has a main channel 12 extending to the first pivot end 11, and a switch group 13 arranged on the main channel 12. The main channel 12 communicates with an air intake on the handle 10. Port 14, the switch group 13 determines the ventilation state of the main channel 12 after being operated by the messenger. Wherein, the ventilation state of the main channel 12 mentioned herein refers to that when the switch group 13 is not operated initially, the pneumatic machine tool 100 does not start, so that the main channel 12 is not conducted and cannot output gas to the tool head 30; 100 is able to drive the tool part 70 to work.

承上，該工具頭30具有一本體31，一設於該本體31的工具件驅動組32，以及二成形於該本體31的樞接臂33，其中，該二樞接臂33並列設置於該本體31的同側，該工具頭30擬與該握柄10樞接時，該工具頭30以該二樞接臂33作為一第二樞接端34，該工具頭30透過一樞軸50令該第二樞接端34與該第一樞接端11進行組接，同時藉由該樞軸50達到相對該握柄10擺動的目的，就如圖7所示。而該工具件驅動組32顧名思義用以驅動該工具件70，一實施例中，該工具件驅動組32包含一氣動馬達321，以及一設於該氣動馬達321上的工作軸322，該工作軸322與該工具件70組接，該工作軸322在該氣動馬達321運轉時受帶動，並驅動該工具件70活動。另外，該本體31成形一提供該工具件驅動組32設置的腔室311，以及至少一連通該腔室311的副流道312，該腔室311可以由單一構件或是複數構件所形成，該腔室311內提供氣體流動其中，使該工具件驅動組32得以被驅動，該至少一副流道312由該腔室311延伸至該二樞接臂33，該副流道312提供氣體承接與導引功能，該副流道312接受進入該工具頭30內，並導引氣體流向該腔室311中。又，該樞軸50具有一轉接流道51以及二連通該轉接流道51的轉接口52，該二轉接口52分別連通該主流道12與該副流道312，該轉接流道51透過該二轉接口52與該主流道12與該副流道312連通。換句話來說，該轉接流道51提供銜接該主流道12與該副流道312的功能，令該主流道12與該副流道312形成一通氣路徑101。On the other hand, the tool head 30 has a body 31, a tool driving group 32 disposed on the body 31, and two pivot arms 33 formed on the body 31. The two pivot arms 33 are arranged side by side on the same side of the body 31. When the tool head 30 is intended to be pivotally connected to the handle 10, the tool head 30 uses the two pivot arms 33 as a second pivot end 34, and the tool head 30 makes the second pivot end 3 through a pivot 50. 4 is assembled with the first pivot end 11, and at the same time achieves the purpose of swinging relative to the handle 10 through the pivot 50, as shown in FIG. 7 . The tool driving unit 32 is used to drive the tool 70 as its name implies. In one embodiment, the tool driving unit 32 includes an air motor 321 and a working shaft 322 mounted on the air motor 321. The working shaft 322 is assembled with the tool 70. The working shaft 322 is driven by the air motor 321 to drive the tool 70 to move. In addition, the main body 31 forms a chamber 311 that provides the tool driving group 32, and at least one secondary channel 312 that communicates with the chamber 311. The chamber 311 can be formed by a single component or a plurality of components. The cavity 311 provides gas to flow therein, so that the tool driving group 32 can be driven. The at least one secondary channel 312 extends from the cavity 311 to the two pivot arms 33. The secondary channel 312 provides gas receiving and guiding. The secondary channel 312 receives the gas into the tool head 30 and guides the gas to flow into the chamber 311 . In addition, the pivot 50 has a transfer channel 51 and two transfer ports 52 connected to the transfer channel 51, the two transfer ports 52 respectively communicate with the main channel 12 and the secondary channel 312, and the transfer channel 51 communicates with the main channel 12 and the secondary channel 312 through the second transfer port 52. In other words, the transfer channel 51 provides the function of connecting the main channel 12 and the secondary channel 312 , so that the main channel 12 and the secondary channel 312 form an air passage 101 .

於後就該氣動工具機100的實施進行說明，請參閱圖4至圖5。假設初始時該氣動工具機100未開始作業，該開關組13未受操作，使該主流道12中未有氣體流動。一旦該開關組13受操作，該開關組13改變該主流道12狀態，使得該主流道12承接由該進氣口14而來的氣體，以向該工具頭30供氣。該主流道12內的氣體經該二轉接口52的其中之一進入該轉接流道51中，於後再經由該二轉接口52的其中另一流出該轉接流道51，以進入該副流道312中。也就是說，該開關組13於後操作後，該主流道12內的氣體將沿該通氣路徑101流入該副流道312中，於後再流入該腔室311中驅動該工具件驅動組32。又，當該氣動工具機100擬停止作業時，該開關組13停止受操作，該主流道12內氣體停止流動，而該通氣路徑101上亦不再有氣體流通，於此當下，該腔室311內不再有氣體進入其中，該工具件驅動組32無法再受驅動，使得該工具件70停止被帶動。The implementation of the pneumatic machine tool 100 will be described later, please refer to FIG. 4 to FIG. 5 . Assuming that the pneumatic machine tool 100 does not start working at the beginning, the switch group 13 is not operated, so that there is no gas flow in the main channel 12 . Once the switch group 13 is operated, the switch group 13 changes the state of the main channel 12 so that the main channel 12 accepts the gas from the air inlet 14 to supply the tool head 30 with gas. The gas in the main channel 12 enters the transfer channel 51 through one of the two transfer ports 52 , and then flows out of the transfer channel 51 through the other of the two transfer ports 52 to enter the secondary channel 312 . That is to say, after the switch group 13 is operated, the gas in the main channel 12 will flow into the secondary channel 312 along the ventilation path 101 , and then flow into the chamber 311 to drive the tool driving group 32 . Moreover, when the pneumatic machine tool 100 is about to stop working, the switch group 13 stops being operated, the gas in the main channel 12 stops flowing, and there is no gas flowing through the ventilation path 101. At this moment, no gas enters into the chamber 311, and the tool driving group 32 can no longer be driven, so that the tool 70 stops being driven.

由上述可知，本發明透過該二樞接臂33的設置，該工具頭30擬與該握柄10組接時，該工具頭30透過該二樞接臂33組接該樞軸50，並樞接於該握柄10上，藉此達到組接與擺動的目的。另外，本發明透過該本體31成形出延伸至該二樞接臂33的其中之一的該副流道312，使得氣流可以更為集中地流入該腔室311內，避免氣流流速過低而造成該氣動工具機100無法正常工作的情況。再者，透過本發明該二樞接臂33與該樞軸50的設置，可改善習用須額外使用大量密封結構才得以建立出通氣路徑的問題。藉此，本發明得以避免習用因密封結構老化或是未確實組裝，導致氣流外洩，進而造成習用氣動工具機的氣流流速過低，無法正常工作的問題。It can be seen from the above that, through the setting of the two pivot arms 33, when the tool head 30 is intended to be assembled with the handle 10, the tool head 30 is assembled with the pivot 50 through the two pivot arms 33 and pivotally connected to the handle 10, thereby achieving the purpose of assembly and swing. In addition, the main body 31 of the present invention forms the secondary channel 312 extending to one of the two pivot arms 33, so that the air flow can flow into the chamber 311 more concentratedly, avoiding the situation that the air machine tool 100 cannot work normally due to the low flow rate of the air flow. Furthermore, through the arrangement of the two pivot arms 33 and the pivot 50 of the present invention, the conventional problem that a large number of sealing structures must be additionally used to establish a ventilation path can be improved. In this way, the present invention can avoid the conventional problem that the air flow is leaked due to aging of the sealing structure or improper assembly, and then the air flow rate of the conventional air tool machine is too low to work normally.

承上，復請參閱圖3至圖4，該樞軸50上成形複數阻氣環53，該些阻氣環53位於該第一樞接端11與該第二樞接端34中，該些阻氣環53限制氣體僅能由該主流道12經該轉接流道51流入該副流道312中，換句話來說，該些阻氣環53主要在於提供氣體阻斷功能，並用以建立出該通氣路徑101。一實施例中，該些阻氣環53為間隔設置，該些阻氣環53位於該二轉接口52的每一的二側，該些阻氣環53的位置不與該二轉接口52重疊。又，本發明該樞軸50上更可設有複數氣密墊圈54，該些氣密墊圈54位於該些阻氣環53上，該些氣密墊圈54提供氣密功能，並輔助該些阻氣環53建立出該通氣路徑101。Referring to FIGS. 3 to 4 again, a plurality of gas blocking rings 53 are formed on the pivot shaft 50 . These gas blocking rings 53 are located in the first pivotal end 11 and the second pivotal end 34 . In one embodiment, the gas blocking rings 53 are arranged at intervals, the gas blocking rings 53 are located on two sides of each of the two transfer ports 52 , and the positions of the gas blocking rings 53 do not overlap with the two transfer ports 52 .

承上，請參閱圖2至圖5，該樞軸50具有一桿體55以及一位於該桿體55一端的頭部56，該樞軸50可直接在該桿體55內部成形出該轉接流道51。當該桿體55於設有該頭部56一端為貫通時，該頭部56作為該些阻氣環53的其中之一，該頭部56阻斷外部與該轉接流道51的導通，限制氣體進入該轉接流道51後必須流向該副流道312中。當該桿體55於未設有該頭部56一端為貫通時，該樞軸50具有一連通該轉接流道51的端口57，該樞軸50與該握柄10及該工具頭30產生樞接時，該端口57被該二樞接臂33的其中之一封閉，該二樞接臂33中封閉該端口57者限制該轉接流道51內的氣體的流動方向。Referring to FIG. 2 to FIG. 5 , the pivot 50 has a rod body 55 and a head 56 at one end of the rod body 55 , and the pivot shaft 50 can directly form the transfer channel 51 inside the rod body 55 . When the rod body 55 is connected at the end where the head 56 is provided, the head 56 acts as one of the gas blocking rings 53, and the head 56 blocks the conduction between the outside and the transfer flow channel 51, restricting the flow of gas into the transfer flow channel 51 to the secondary flow channel 312. When the end of the rod body 55 not provided with the head 56 is through, the pivot 50 has a port 57 communicating with the transfer channel 51.

再另一方面，復請參閱圖2、圖3與圖6，該握柄10具有一提供該開關組13設置的的身部17，以及一連接該身部17的頸部18，該頸部18作為該握柄10的該第一樞接端11，且該頸部18相較於該身部17為窄，以伸入該二樞接臂33之間。又，該身部17與該頸部18可以是一體成形結構，也可以是兩個獨立構件。當該身部17與該頸部18為兩獨立構件時，該頸部18成形一組接該身部17的組裝結構181，令該身部17與該頸部18共同成形出該主流道12。又，本發明為避免該身部17與該頸部18脫離，該身部17成形至少一與該頸部18組接的定位柱172。此外，該身部17成形一提供該開關組13設置其中的容置孔171，該容置孔171連通該主流道12，令該開關組13受操作後決定該主流道12是否導通。On the other hand, referring to FIGS. 2, 3 and 6, the handle 10 has a body 17 provided with the switch group 13, and a neck 18 connected to the body 17. The neck 18 is used as the first pivotal end 11 of the handle 10, and the neck 18 is narrower than the body 17 to extend between the two pivotal arms 33. Moreover, the body 17 and the neck 18 can be integrally formed, or two independent components. When the body 17 and the neck 18 are two independent components, the neck 18 forms an assembly structure 181 connecting the body 17 so that the body 17 and the neck 18 jointly form the main channel 12 . Moreover, in order to prevent the body 17 from being separated from the neck 18 in the present invention, the body 17 is formed with at least one positioning post 172 assembled with the neck 18 . In addition, the body 17 is formed with an accommodating hole 171 in which the switch set 13 is disposed, and the accommodating hole 171 communicates with the main flow channel 12 , so that the switch set 13 is operated to determine whether the main flow channel 12 is conducting.

承上，本發明該握柄10具有一設於該身部17的操作壓板19，該操作壓板19受該使用者操作並用以驅動該開關組13。又，該開關組13包含一導流閥131，一設於該導流閥131內的活動塞132，以及一抵頂該活動塞132的彈簧133，該導流閥131具有一導流道134，該活動塞132受該操作活動塞132受該操作壓板19控制，並在常態下受該彈簧133推抵而封閉該導流道134。也就是說，當該操作壓板19未控制該活動塞132時，該活動塞132將阻斷該導流道134與該主流道12的連通，使該主流道12內的氣體無法流入該轉接流道51中。當該操作壓板19壓迫該活動塞132時，該活動塞132釋放該導流道134，令該導流閥131與該主流道12連通，使該主流道12內的氣體可以流入該轉接流道51中。一實施例中，本發明該握柄10成形一設於該身部17並提供該操作壓板19組裝的組裝凸塊20，該組裝凸塊20成形一開孔201，該開孔201提供該操作壓板19的一組裝桿191設置，以令該操作壓板19組裝於該組裝凸塊20後可相對該開關組13位移。In addition, the handle 10 of the present invention has an operating pressing plate 19 disposed on the body 17 , and the operating pressing plate 19 is operated by the user to drive the switch group 13 . Moreover, the switch group 13 includes a diversion valve 131, a movable plug 132 disposed in the diversion valve 131, and a spring 133 against the movable plug 132. That is to say, when the operating platen 19 does not control the movable plug 132 , the movable plug 132 will block the communication between the guide channel 134 and the main channel 12 , so that the gas in the main channel 12 cannot flow into the transfer channel 51 . When the operating platen 19 presses the movable plug 132 , the movable plug 132 releases the diversion channel 134 , so that the diversion valve 131 communicates with the main channel 12 , so that the gas in the main channel 12 can flow into the transfer channel 51 . In one embodiment, the handle 10 of the present invention is formed with an assembly projection 20 disposed on the body 17 and provided for assembling the operation pressing plate 19. The assembly projection 20 forms an opening 201, and the opening 201 provides an assembly rod 191 of the operation pressing plate 19 so that the operation pressing plate 19 can be displaced relative to the switch group 13 after being assembled on the assembly projection 20.

承上，於另一實施例中，該主流道12以該開關組13區分為一設有該進氣口14的進氣段123，以及一位於靠近該轉接流道51一側的出氣段124，該導流閥131的該導流道134分別面對該進氣段123與該出氣段124，當該活動塞132封閉該導流道134時，該進氣段123無法連通該出氣段124，反之，該進氣段123則可連通該出氣段124。又，由側視角度觀察該氣動工具機100，該進氣段123的一延伸線125與該出氣段124的一延伸線126交錯於一點。在另一實施例中，該握柄10成形一與該主流道12連通的空間21，該空間21的主要功能在於提供該握柄10輕量化的功能。須了解到，該空間21未面對該進氣口14的一端未與該副流道312連通，該空間21不替代該主流道12輸送氣體。As above, in another embodiment, the main channel 12 is divided by the switch group 13 into an air inlet section 123 provided with the air inlet 14, and an air outlet section 124 located on a side close to the transfer flow channel 51. The flow guide channel 134 of the diversion valve 131 faces the air intake section 123 and the air outlet section 124 respectively. When the movable plug 132 closes the flow guide channel 134, the air inlet section 123 cannot communicate with the air outlet section 124. On the contrary, the inlet section 123 can communicate with the outlet section 124 . Moreover, when viewing the pneumatic machine tool 100 from a side view, an extension line 125 of the air inlet section 123 and an extension line 126 of the air outlet section 124 intersect at one point. In another embodiment, the handle 10 forms a space 21 communicating with the main channel 12 , and the main function of the space 21 is to provide the handle 10 with a lightweight function. It should be understood that the end of the space 21 not facing the air inlet 14 is not in communication with the secondary channel 312 , and the space 21 does not replace the main channel 12 to deliver gas.

另外，於本實施例中，該工具頭30具有至少一設於該本體31上的排氣口38，該排氣口38連通該腔室311與外部，以提供進入該腔室311的氣體排出。此外，另一實施例中，本發明該工具頭30具有至少一成形於該本體31上的維修開口39，該維修開口39具有利於拆卸該本體31以便於維修該工具件驅動組32的功能。In addition, in this embodiment, the tool head 30 has at least one exhaust port 38 disposed on the body 31 , and the exhaust port 38 communicates the chamber 311 with the outside to provide the gas entering the chamber 311 to be discharged. In addition, in another embodiment, the tool head 30 of the present invention has at least one maintenance opening 39 formed on the body 31 , and the maintenance opening 39 has a function of facilitating disassembly of the body 31 for maintenance of the tool drive unit 32 .

綜上所述者，僅爲本發明的一較佳實施例而已，當不能以此限定本發明實施的範圍，即凡依本發明申請專利範圍所作的均等變化與修飾，皆應仍屬本發明的專利涵蓋範圍。To sum up, the above is only a preferred embodiment of the present invention, and should not limit the scope of the present invention, that is, all equivalent changes and modifications made according to the scope of the patent application of the present invention should still belong to the scope of the patent of the present invention.
