Description
本創作係有關於一種傳動裝置,特別是指一種換刀臂之傳動裝置,其利用兩個馬達驅動分別驅動單一傳動軸進行旋轉及昇降動作,以便用於工具機之換刀作業。The present invention relates to a transmission device, in particular to a transmission device for a tool changer, which uses two motors to drive a single drive shaft to perform a rotation and lifting operation for use in a tool change operation.
按,習知工具機的換刀軸結構,主要是利用一驅動單元帶動一換刀軸執行旋轉及上下往復運動,以便進行換刀作業。According to the conventional tool changer shaft structure, a drive unit is used to drive a change tool shaft to perform rotation and up and down reciprocation to perform a tool change operation.
其中,驅動單元通常包括一凸輪、一搖臂及一換刀軸,凸輪具有一朝向搖臂的環狀凹槽及一設於周緣的滾動槽,搖臂具有一滾動件設於環狀凹槽,而換刀軸具有一能與凸輪的滾動槽嚙合的滾動軸承,且換刀軸供搖臂一端連接;當凸輪旋轉時,滾動件能沿環狀凹槽移動,藉此帶動搖臂往復擺動,搖臂促使換刀軸呈上下往復作動,而當凸輪轉動時,透過滾動槽與滾動軸承的接觸關係,以連動換刀軸轉動,藉以運用於工具機之換刀臂的移動與旋轉動作,並執行換刀作業。The driving unit generally includes a cam, a rocker arm and a tool changer shaft. The cam has an annular groove facing the rocker arm and a rolling groove disposed at the periphery. The rocker arm has a rolling member disposed on the annular groove. The tool change shaft has a rolling bearing capable of meshing with the rolling groove of the cam, and the tool change shaft is connected to one end of the rocker arm; when the cam rotates, the rolling member can move along the annular groove, thereby driving the rocker arm to reciprocate and swing, The rocker arm causes the tool change shaft to reciprocate up and down, and when the cam rotates, through the contact relationship between the rolling groove and the rolling bearing, the tool change shaft is rotated, so as to be used for the movement and rotation of the tool changer of the machine tool, and executed Tool change operation.
然而,習知採用凸輪作為換刀軸的旋轉與上下往復動作的操控,礙於凸輪結構製造成本高,且滾動件與環狀凹槽在常時間運作下容易磨損,而產生配合精度不佳,導致運轉不夠精準,影響加工作業,且整體結構亦為複雜,安裝與維修顯得麻煩;此外,凸輪需要預留停止角以便轉動運作,如此導致爬升角過小,而造成阻力過大,致使換刀動作定位無法精確。However, conventionally, the cam is used as the rotation of the tool change shaft and the manipulation of the up and down reciprocating motion, which is disadvantageous in the high manufacturing cost of the cam structure, and the rolling member and the annular groove are easy to wear under normal operation, and the fitting precision is poor. The operation is not accurate enough, affecting the machining operation, and the overall structure is also complicated, and the installation and maintenance are troublesome. In addition, the cam needs to reserve the stopping angle for the rotation operation, so that the climbing angle is too small, and the resistance is too large, resulting in the positioning of the tool change. Unable to be precise.
為解決上述課題,本創作揭露一種換刀臂之傳動裝置,其利用兩個馬達驅動分別驅動單一傳動軸進行旋轉及昇降動作,以便用於工具機之換刀作業。In order to solve the above problems, the present invention discloses a gear changer transmission device that uses two motors to drive a single drive shaft to perform a rotation and a lift operation for use in a tool change operation.
