Description
本發明係關於一種夾頭結構，尤指一種前置式迴轉夾頭。 The invention relates to a chuck structure, especially a pre-rotating chuck.
按，夾頭是一般車床機具等加工時夾持固定工作必要的工具，其因為加工時係用以夾持住工件，隨其轉動做加工操作之工具，而以近年來為求加工鎖固工具的平穩安全及操作控制的迅速，通常都設由其中內設氣壓的管路，驅控內部的夾爪塊做移位夾放工件的操作，但由於氣壓夾頭結構係於夾頭停止轉動的時候供壓，運轉時不給壓僅透過保壓結構達到夾持狀態，再透過內部O型環達到氣密保壓，因此，當夾頭本體隨工件夾持轉動加工時，會因O型環的老化、疲乏而發生洩漏的失壓情形，或是因為O型環的裝配精度而影響保壓效果，導致夾持穩定度會因運轉時間而持續降低，使得工件夾持上較不穩定，作業過程中存在著風險，輕者影響加工品質，造成精密度的降低，嚴重者更可能產生工件飛出而有工安意外傷害，危險性極高，缺乏安全性。 According to the press, the chuck is a tool that is necessary for clamping and fixing work during the processing of general lathe tools, etc., because it is used to hold the workpiece during processing, and it is used as a tool for processing operations with its rotation. The smooth and safe operation and rapid operation control are usually provided with a pipeline with air pressure inside, which drives the internal gripper block to shift and place the workpiece. However, due to the structure of the pneumatic chuck, the chuck stops rotating. When the pressure is supplied, the pressure is not applied during operation, and the clamping state is reached only through the pressure-retaining structure, and then the airtight pressure-retaining is achieved through the internal O-ring. Therefore, when the chuck body rotates with the workpiece, the O-ring The pressure loss caused by the aging or fatigue of the leak, or because the assembly accuracy of the O-ring affects the pressure holding effect, resulting in the continuous reduction of the clamping stability due to the running time, which makes the workpiece clamping unstable and work There are risks in the process. The lighter ones may affect the processing quality, resulting in a decrease in precision.

反之，當夾頭本體20欲放鬆工件時，則再依序由第6、5圖所示觀之，係由第二油孔14之掣動油管加壓輸入掣動油，並經由該第二輸油槽113流入該夾頭本體於套接部22外徑之第二導油孔222，且沿著第二導槽224進入該後蓋40之導引流道44，最後灌入該腔室23之入油室232內，進而將掣動油從後蓋40灌入並推動活塞環33往限位環32方向滑動位移，同時帶動該滑動環座24沿著腔室23滑移作動，使得各該夾爪滑塊25之導塊251因滑動環座24復位而沿著各該斜錐導槽241外擴位移，達到夾爪滑塊25放鬆工件之目的，而原先介於該活塞環33以及限位環32間之掣動油則會因該活塞環33移動而往限位環32方向擠壓，進而經由第一導槽223以及第一導油孔221流出，並容置於該環座10之第一輸油槽112間，並透過第一油孔13之掣動油管未經加壓的供油狀態，讓掣動油可於第一輸油槽112內形成保壓效果。 Conversely, when the chuck body 20 wants to loosen the workpiece, it is then sequentially viewed from Figs. 6 and 5, and the depressing oil is pressurized by the depressing oil pipe of the second oil hole 14 and passes through the second The oil transfer groove 113 flows into the second oil guide hole 222 of the chuck body at the outer diameter of the sleeve portion 22, and enters the guide flow path 44 of the rear cover 40 along the second guide groove 224, and finally fills the cavity 23 Into the oil chamber 232, and then pours detent oil from the rear cover 40 and pushes the piston ring 33 to slide in the direction of the limit ring 32, and at the same time drives the sliding ring seat 24 to slide along the chamber 23 to make each The guide block 251 of the jaw slider 25 is expanded and displaced along each inclined cone guide groove 241 due to the reset of the slide ring seat 24, so as to achieve the purpose of the jaw slider 25 to relax the workpiece, which was originally interposed between the piston ring 33 and The detent oil between the limit rings 32 will be squeezed in the direction of the limit ring 32 due to the movement of the piston ring 33, and then flow out through the first guide groove 223 and the first oil guide hole 221, and be accommodated in the ring seat Between the first oil delivery tank 112 and the unpressurized oil supply state through the detent oil pipe of the first oil hole 13, the detent oil can form a pressure maintaining effect in the first oil delivery tank 112.
藉上述具體實施例之結構，可得到下述之效益：(一)本創作之夾頭本體20係利用油壓方式控制該連動單元30滑移作動，進而連動該滑動環座24達到各該夾爪滑塊25的夾持、放鬆，且該夾頭本體20實際運轉時，該第一油孔13之掣動油壓力係持續輸入，同時將活塞環33與後蓋40間之掣動油排出，使活塞環33得以確實往後蓋40方向位移達到夾持狀態，大幅提升結構之夾持力道，以及確保夾頭本體20運轉時的夾持穩定度，而且運轉時還能同時透過掣動油滯留於第一、二輸油槽112、113而達到潤滑、降溫的效果，有效降低夾頭本體20運轉過程中有過熱變形之疑慮，更能支持於高轉速的加工作業，進而提升加工效率及使用時限。
With the structure of the above specific embodiment, the following benefits can be obtained: (1) The
(二)該夾頭本體20進行工件的夾持、放鬆作動時，係利用一進一出的釋壓回流，達到夾頭本體20與環座10間之油路平衡，大幅降低單邊壓力過大而有變型之疑慮，提升結構使用壽命。
