Description
本創作係與加工用的機床相關，尤其是指一種特別設置鎖刀控制組件來控制鎖刀之能提前作動的換刀裝置。This creation is related to the machine tool for machining, especially a tool change device that specially sets the lock knife control unit to control the lock knife to be actuated in advance.
隨著加工需求與加工技術的日益進步，現有的工具機通常設置刀庫來儲放各種規格的刀具，刀庫所存放的刀具能循環移動，且根據加工需求而透過換刀機構與加工主軸上的刀具作替換使用。With the increasing processing requirements and processing technology, the existing machine tools usually set up a tool magazine to store various specifications of the tool. The tools stored in the tool magazine can be moved cyclically, and through the tool change mechanism and the machining spindle according to the processing requirements. The tool is used interchangeably.
一種如TW證書號M413563專利案中所揭示的刀庫換刀臂結構改良，其包括有機座、換刀臂、推抵件以及頂掣件；其中，換刀臂組裝設於機座且於端部設有扣刀口；推抵件裝設於換刀臂的內部，且推抵件受到壓縮彈簧的推抵，而使推抵件的前端能朝向扣刀口突出；頂掣件裝設於換刀臂的內部且受到另一壓縮彈簧推抵，而使頂掣件撐抵於推抵件的後端，並且讓頂掣件的一部分突出換刀臂。An improved tool changer arm structure disclosed in the TW certificate number M413563 patent, which comprises an organic seat, a tool change arm, a pusher and a top member; wherein the tool change arm is assembled on the machine base and is at the end The part is provided with a buckle edge; the pushing member is installed inside the tool change arm, and the pushing member is pushed by the compression spring, so that the front end of the pushing member can protrude toward the buckle edge; the top piece is mounted on the tool changer The inside of the arm is pushed against by another compression spring, so that the top jaw abuts against the rear end of the pushing member, and a portion of the top member protrudes from the tool change arm.
這類型的換刀臂結構，其換刀臂必須要朝向機座移動，並且以頂掣件突出換刀臂的一部分抵靠機座，才能使頂掣件壓抵壓縮彈簧、離開推抵件，並且空出供推抵件後退的空間，這時，推抵件的後端能後退，因此換刀臂結構處於未鎖刀的狀態。In this type of tool change arm structure, the tool change arm must be moved toward the base, and a part of the change arm protrudes against the base with the top piece, so that the top piece can be pressed against the compression spring and away from the pusher. And the space for the push back is vacated, and at this time, the rear end of the pusher can be retracted, so the structure of the change arm is in an unlocked state.
而當扣刀口扣合固定刀具時，其換刀臂必須要離開機座，頂掣件受到壓縮彈簧的推抵而復位，並且重新撐抵於頂抵件的後端，由於頂抵件的後端受到頂掣件的抵靠而無法向後退讓，使得換刀臂結構處於鎖刀狀態，讓頂抵件能與扣刀口共同限制刀具。When the knife edge is fastened to the fixed tool, the tool change arm must leave the base, and the top jaw is reset by the compression spring, and is re-supported to the rear end of the top abutment. The end is abutted by the top jaw and cannot be retracted, so that the tool change arm structure is in the state of the lock knife, so that the top abutment can jointly limit the cutter with the buckle edge.
然而，在換刀臂離開機座的瞬間，刀具仍有可能因晃動而導致重心偏移，使得刀具在換刀臂離開機座的過程中脫離扣刀口而掉落；因此，如何改進鎖刀的機制，在換刀臂離開機座之前，便使換刀臂結構能提前處在鎖刀狀態，係為相關從業人員努力研發的方向之一。However, at the moment when the tool change arm leaves the machine base, the tool may still be displaced due to the sway, so that the tool falls off the buckle edge during the process of the tool change arm leaving the machine base; therefore, how to improve the lock knife The mechanism makes the structure of the tool change arm ahead of the lock knife before the tool change arm leaves the machine base, which is one of the directions that the relevant practitioners are striving to develop.
為了解決現有的換刀臂結構在換刀臂離開機座之前未處於鎖刀狀態，而導致換刀臂離開機座的瞬間，刀具重心偏移而脫離扣刀口而掉落的問題，本創作提出一種能提前鎖刀的換刀裝置，其增設有專門用於驅動、控制鎖刀與否的鎖刀控制組件，使得換刀臂裝置在換刀臂離開機座之前，即處於鎖刀狀態，能提升替換刀具時的穩定性。In order to solve the problem that the existing tool change arm structure is not in the lock knife state before the tool change arm leaves the machine base, and the tool change arm is separated from the machine base, the tool center of gravity is offset and falls off the buckle edge and is dropped. A tool change device capable of locking a knife in advance, which is provided with a lock knife control component specially used for driving and controlling the lock knife, so that the tool change arm device is in a lock knife state before the tool change arm leaves the machine seat, Improve stability when replacing tools.

如圖3及圖4所示，當該換刀臂組件20移近該本體10而欲進行換刀時，本創作處於鎖刀狀態，各夾爪組件30的兩夾制件31對合夾制刀具；接著，該鎖刀控制組件40之驅動單元41的驅動桿411向下作動，透過結合於該驅動桿411的該接頭45，與結合於該接頭45的該凸輪軸承46拉動該連結件43，使與該連結件43相結合的該頂抵單元42以該滑套組件12為中心而朝向圖4的逆時針方向轉動，結合於該頂抵單元42之轉動件421的兩該頂抵塊422隨著轉動；如圖5所示，接下來同樣以組裝於該換刀臂本體21之第一裝設端的一該夾爪組件30來作說明：一該頂抵塊422以所設的斜面4221逐漸頂抵該夾爪組件30之擋止件34的抵頂段343，該擋止件34逐漸朝向該換刀臂組件20的一該擋塊22移動，且逐漸壓縮該夾爪組件30的壓縮彈簧35；如圖6、圖7及圖8所示，當該擋止件34的撐抵段341退出該夾爪組件30的兩夾制件31之間時，該夾爪組件30的拉伸彈簧33便會處於未拉伸的狀態，該拉伸彈簧33將兩該夾制件31的兩抵靠端拉近，使兩該夾制件31的兩夾制端張開，讓本創作處於未鎖刀的狀態，此時刀庫的刀具便能進入兩該夾制件31之間。As shown in FIG. 3 and FIG. 4, when the tool changer arm assembly 20 is moved closer to the body 10 and the tool change is to be performed, the present invention is in a state of locking the knife, and the two clamp members 31 of the jaw assemblies 30 are clamped together. Then, the driving rod 411 of the driving unit 41 of the locking knife control assembly 40 is actuated downwardly, and the connecting member 43 is pulled by the cam bearing 46 coupled to the joint 45 through the joint 45 coupled to the driving rod 411. The abutting unit 42 coupled with the connecting member 43 is rotated in the counterclockwise direction of FIG. 4 centering on the sliding sleeve assembly 12, and the two abutting blocks of the rotating member 421 of the abutting unit 42 are coupled. 422 is rotated; as shown in FIG. 5, the following is also illustrated by a jaw assembly 30 assembled to the first mounting end of the tool changer body 21: a top bevel block 422 is provided with a bevel 4221 gradually abuts against the abutting portion 343 of the stop member 34 of the jaw assembly 30, the stop member 34 gradually moves toward a stop 22 of the tool change arm assembly 20, and gradually compresses the jaw assembly 30. a compression spring 35; as shown in FIGS. 6, 7, and 8, when the abutment portion 341 of the stopper 34 is withdrawn from the jaw assembly 30 When the pieces 31 are between, the tension springs 33 of the jaw assembly 30 are in an unstretched state, and the tension springs 33 pull the two abutting ends of the two clamping members 31 closer to each other. The two clamping ends of the piece 31 are opened, so that the creation is in an unlocked state, and the tool of the magazine can enter between the two clamping members 31.
如圖4、圖9及圖10所示，當該夾爪組件30欲夾制刀具時，該驅動單元41的驅動桿411向上作動，使該頂抵單元42以該滑套組件12為中心而朝向圖4的順時針方向轉動，該頂抵塊422離開該擋止件34，該擋止件34受到該壓縮彈簧35的推動而復位，且重新將兩該夾制件31的兩抵靠端撐開，使兩該夾制件31的兩夾制端對合夾制刀具。As shown in FIG. 4, FIG. 9 and FIG. 10, when the jaw assembly 30 is to be clamped, the driving rod 411 of the driving unit 41 is actuated upward, so that the abutting unit 42 is centered on the sliding sleeve assembly 12. Rotating in the clockwise direction of FIG. 4, the abutting block 422 is separated from the stopping member 34, and the stopping member 34 is pressed by the compression spring 35 to be reset, and the two abutting ends of the two clamping members 31 are re-attached. The opening is performed so that the two clamping ends of the two clamping members 31 are combined to form a cutter.
本創作之能提前鎖刀的換刀裝置，其增設有專門用於驅動、控制鎖刀與否的該鎖刀控制組件40，該鎖刀控制組件40能利用所設的驅動單元41來驅動該頂抵單元42轉動，讓該頂抵單元42的兩頂抵塊422能分別且選擇性地抵靠於兩該夾爪組件30的兩擋止件34，兩該頂抵塊422在該換刀臂組件20離開該本體10之前，便能隨著該頂抵單元42之轉動件421的轉動，而分別離開兩該擋止件34，使各夾爪組件30的擋止件34再次復位而介於各夾爪組件30的兩夾制件31之間，使得本創作處於鎖刀狀態；與現有的換刀臂結構相比，本創作能在該換刀臂組件20離開該本體10之前，便提前處在鎖刀狀態，能提升替換刀具時的穩定性。The tool change device capable of locking the knife in advance is provided with the lock knife control assembly 40 for driving or controlling the lock knife. The lock knife control assembly 40 can drive the drive unit 41 by using the drive unit 41. The abutting unit 42 is rotated, so that the two abutting blocks 422 of the abutting unit 42 can respectively and selectively abut against the two stopping members 34 of the two jaw assemblies 30, and the two abutting blocks 422 are in the tool changing Before the arm assembly 20 leaves the body 10, the two retaining members 34 can be separated from each other with the rotation of the rotating member 421 of the abutting unit 42 to reset the blocking member 34 of each jaw assembly 30 again. Between the two clamps 31 of each jaw assembly 30, the creation is in the state of the lock knife; compared to the existing tool change arm structure, the creation can be before the change arm assembly 20 leaves the body 10 It is in the state of locking knife in advance, which can improve the stability when replacing the tool.
