Abstract
Description
本發明與修邊機有關，特別是指一種修邊機之刀具深度調整裝置。The present invention relates to a trimming machine, and particularly refers to a tool depth adjustment device of a trimming machine.
修邊機可以搭配不同的刀具將木材之邊緣加工成相對應的形狀，例如開槽、修邊或倒角等，為了滿足不同的加工需求，刀具的深度必須能夠作適時的調整，就相關的先前技術來說，如中華民國公告第I395649號所揭露之修邊機主要是利用一快拆結構來固定主體相對於固定框的高度位置，進而達到調整刀具深度的效果。然而在前述專利案中，在調整時需要反覆地鬆開與鎖緊快拆結構，操作上顯得相當麻煩，此外，快拆結構所能提供的穩定性有限，容易受到加工時所引起的震動而產生鬆動，導致加工精度亦會連帶受到影響。The trimming machine can be matched with different tools to process the edges of the wood into corresponding shapes, such as grooving, trimming or chamfering. In order to meet different processing requirements, the depth of the tool must be able to be adjusted in time. In the prior art, the trimming machine disclosed in the Republic of China Announcement No. I395649 mainly uses a quick-release structure to fix the height of the main body relative to the fixed frame, thereby achieving the effect of adjusting the depth of the tool. However, in the aforementioned patent case, it is necessary to repeatedly loosen and lock the quick-release structure during adjustment, which is quite troublesome in operation. In addition, the stability that the quick-release structure can provide is limited, and it is susceptible to vibration caused by processing. The looseness will cause the machining accuracy to be affected.
又已知中國公告號第201361737號實用新型說明了一種修邊機，其通過轉動設有凸輪的切換鈕19的方式或者是轉動為螺釘形式的切換鈕19來使調節桿5的第一螺絲部分6嚙合或脫離第二螺絲部分7，進而調整電機外殼1到所需要的深度。然而上述實用新型須通過磁鐵20來吸引調節桿5的第一螺紋部分6，使調節桿5和第二螺紋部分7分開，磁鐵20並非是作用於切換鈕19，其作用方式較為複雜，因此尚有改善空間。It is also known that the utility model of China Announcement No. 201361737 describes a trimming machine, which turns the switch button 19 provided with a cam or the switch button 19 in the form of a screw to make the first screw part of the adjusting rod 5 6 Engage or disengage the second screw part 7, and then adjust the motor housing 1 to the required depth. However, the above-mentioned utility model requires the
本發明之主要目的在於提供一種修邊機之刀具深度調整裝置，其操作方便且在調整定位後不易鬆動，以增加使用上的便利性及穩定性。The main purpose of the present invention is to provide a tool depth adjusting device of a trimming machine, which is easy to operate and not easy to loosen after adjusting and positioning, so as to increase the convenience and stability of use.
為了達成上述主要目的，本發明之刀具深度調整裝置包含有一基座、一齒條、一壓板、一蝸輪，以及一彈性件。該基座可上下位移地套設於一馬達外殼；該齒條設於該馬達外殼之外周面；該壓板樞設於該基座且能相對該基座於一第一位置與一第二位置之間作動；該蝸輪樞設該壓板之一端，當該壓板位於該第一位置時，該蝸輪脫離該齒條，使得該基座可連同該壓板及該蝸輪一起相對該馬達外殼上下快速位移來進行刀具深度的粗調，當該壓板位於該第二位置時，該蝸輪嚙接於該齒條，此時即可轉動該蝸輪，使該蝸輪連同該壓板及該基座一起沿著該齒條上下位移來進行刀具深度的微調；該彈性件作用於該壓板，用以提供彈力將該壓板保持在該第二位置。In order to achieve the above main objective, the tool depth adjusting device of the present invention includes a base, a rack, a pressing plate, a worm gear, and an elastic member. The base is sleeved on a motor housing such that it can move up and down; the rack is provided on the outer peripheral surface of the motor housing; the pressure plate is pivoted on the base and can be at a first position and a second position relative to the base The worm wheel is pivoted at one end of the pressure plate, and when the pressure plate is in the first position, the worm wheel is separated from the rack, so that the base can move up and down quickly relative to the motor housing together with the pressure plate and the worm gear Perform rough adjustment of the tool depth. When the pressing plate is in the second position, the worm gear is engaged with the rack, and the worm wheel can be rotated at this time so that the worm wheel, the pressing plate and the base are along the rack The up and down displacement is used to fine-tune the depth of the tool; the elastic member acts on the pressing plate to provide elastic force to keep the pressing plate at the second position.
由上述可知，本發明之刀具深度調整裝置利用該齒條與該蝸輪的配合來微調該刀具的加工深度，以提升加工精度，並且在調整定位後利用兩者之間的嚙合效果而不易鬆動，以增加操作上的便利性及穩定性。It can be seen from the above that the tool depth adjusting device of the present invention uses the cooperation of the rack and the worm gear to fine-tune the processing depth of the tool to improve the processing accuracy, and uses the meshing effect between the two to prevent loosening after adjusting the positioning. To increase the convenience and stability of operation.
更佳地，該壓板藉由一銷件樞設於該基座，該彈性件為一扭力彈簧且具有一螺旋部、一第一端部及一第二端部，該螺旋部套設於該銷件，該第一端部一體地連接於該螺旋部且抵靠於該壓板，該第二端部一體地連接於該螺旋部且抵靠於一套環部的外周面。藉此，當該壓板受外力作用而位於該第一位置時，該壓板會抵壓於該彈性件之第一端部，使該彈性件之第一端部蓄積回復力，一旦外力解除之後，該彈性件之第一端部即可將該壓板頂回至該第二位置。More preferably, the pressure plate is pivoted to the base by a pin, the elastic member is a torsion spring and has a spiral part, a first end and a second end, and the spiral part is sleeved on the base. For the pin, the first end portion is integrally connected to the spiral portion and abuts against the pressure plate, and the second end portion is integrally connected to the spiral portion and abuts against the outer peripheral surface of the collar portion. Thereby, when the pressure plate is located at the first position by an external force, the pressure plate will press against the first end of the elastic member, so that the first end of the elastic member accumulates a restoring force. Once the external force is released, The first end of the elastic member can push the pressure plate back to the second position.
更佳地，該壓板具有一調整螺孔，該調整螺孔內設有一調整螺絲，當該調整螺絲之末端推頂於該基座之外周面時，該壓板帶動該蝸輪朝遠離該齒條的方向樞轉，如此即可調整該蝸輪相對於該齒條的嚙合位置，使兩者保持適當的嚙合程度，以避免過緊或過鬆而影響操作效果。More preferably, the pressing plate has an adjusting screw hole, and an adjusting screw is arranged in the adjusting screw hole. When the end of the adjusting screw is pushed against the outer peripheral surface of the base, the pressing plate drives the worm gear to move away from the rack By pivoting in the direction, the meshing position of the worm gear relative to the rack can be adjusted to keep the two meshes at an appropriate degree to avoid over-tightening or over-loosening which would affect the operating effect.
有關本發明所提供對於修邊機之刀具深度調整裝置的詳細構造、特點、組裝或使用方式，將於後續的實施方式詳細說明中予以描述。然而，在本發明領域中具有通常知識者應能瞭解，該等詳細說明以及實施本發明所列舉的特定實施例，僅係用於說明本發明，並非用以限制本發明之專利申請範圍。The detailed structure, characteristics, assembly or use of the tool depth adjusting device for the trimming machine provided by the present invention will be described in the detailed description of the subsequent embodiments. However, those with ordinary knowledge in the field of the present invention should be able to understand that these detailed descriptions and specific examples for implementing the present invention are only used to illustrate the present invention, and are not intended to limit the scope of the patent application of the present invention.
申請人首先在此說明，在以下將要介紹之實施例以及圖式中，相同之參考號碼，表示相同或類似之元件或其結構特徵。The applicant first explains here that in the following embodiments and drawings, the same reference numbers indicate the same or similar elements or structural features.
請先參閱第1圖，圖中所示之修邊機10包含有一馬達外殼12，馬達外殼12之內部安裝有一馬達(圖中未示)，馬達之一驅動軸14穿出馬達外殼12之底端，用以跟一刀具(圖中未示)進行組裝。請再參閱第2圖，本發明之刀具深度調整裝置20包含有一基座30、一齒條40、一壓板50、一蝸輪60及一彈性件70。Please refer to Figure 1 first. The
基座30具有一套環部31與一底框部34。套環部31套設於馬達外殼12且利用一快拆件36加以固定，套環部31具有二相對之凸耳32與一位於該二凸耳32之間之鏤空槽33；底框部34一體地連接於套環部31之底端，用以抵靠於工件之表面，底框部34之中央具有一軸孔35，軸孔35用來讓刀具能夠跟馬達之驅動軸14進行組裝。藉此，透過調整基座30相對於馬達外殼12的高度，即可調整刀具的加工深度。The
齒條40設於馬達外殼12之外周面，而且，齒條40的一部分對應於基座30之套環部31的鏤空槽33。The
壓板50之中央利用一銷件53樞設於基座30之套環部31的凸耳32，使得壓板50能在一第一位置P1(如第5圖所示)與一第二位置P2(如第4圖所示)之間相對基座30樞轉。此外，壓板50之一端具有一按壓部51，壓板50之另一端具有二相對之臂部52，而且壓板50面向套環部31的一內周面上還設有一定位部56(如第3圖所示)。The center of the
蝸輪60利用一銷件62樞設於壓板50之該二臂部52之間，使得蝸輪60能跟著壓板50一起作動。藉此，當壓板50位於如第5圖所示之第一位置P1時，蝸輪60脫離齒條40，當壓板50位於如第4圖所示之第二位置P2時，蝸輪60經由鏤空槽33嚙接於齒條40。The
彈性件70為一扭力彈簧且具有一螺旋部71、一第一端部72及一第二端部73，如第2及4圖所示，螺旋部71套設於銷件53，第一端部72一體地連接於螺旋部71且抵靠於壓板50之定位部56，第二端部73一體地連接於螺旋部71且抵靠於套環部31的外周面。藉此，彈性件70主要提供彈力給壓板50，使壓板50保持在如第4圖所示之第二位置P2。The
由上述可知，當要調整刀具的加工深度時，首先鬆開快拆件36，接著施加外力於壓板50之按壓部51，使壓板50從如第4圖所示之第二位置P2樞轉至如第5圖所示之第一位置P1，此時的蝸輪60會跟齒條40脫離，同時壓板50之按壓部51會擠壓彈性件70之第一端部72，以蓄積彈性件70之第一端部72的回復力，這時候的馬達外殼12即可相對基座30作大幅度的上下位移來對刀具的加工深度達到粗調效果。待調整到接近理想的位置時，釋放施加於壓板50之按壓部51的外力，使壓板50利用彈性件70之第一端部72的回復力從如第5圖所示之第一位置P1回到如第4圖所示之第二位置P2，使蝸輪60嚙接於齒條40，此時即可開始轉動蝸輪60，使蝸輪60連同壓板50及基座30一起沿著齒條40上下位移來對刀具進行加工深度的微調，直到調整到定位為止後鎖緊快拆件36將基座30固緊於馬達外殼12。It can be seen from the above that when the machining depth of the tool is to be adjusted, the
另一方面，為了使蝸輪60與齒條40保持適當的嚙合鬆緊度，壓板50之底部具有一調整螺孔54，在調整螺孔54內設有一調整螺絲55，當調整螺絲55之末端推頂於基座30之套環部31的外周面時，如第6及7圖所示，壓板50會以銷件53為軸心帶動蝸輪60朝遠離齒條40的方向偏轉，如此即可調整蝸輪60與齒條40之間的嚙合位置，以避免兩者因過緊而造成結構損壞，或者是因過鬆而產生操作失效的問題。On the other hand, in order to maintain proper meshing tightness between the
綜上所陳，本發明之刀具深度調整裝置20利用齒條40與蝸輪60的配合來快速微調刀具的加工深度，以增加操作上的便利性及有效提升加工精度，並且在調整定位後利用兩者之間的嚙合關係所產生的鎖定效果，使整體結構不易鬆動，以增加操作上的穩定性。To sum up, the tool
