However, in order to achieve the purpose of the second purpose, the bearings 122 and 122, the outer ring sleeve 127 and the fixed seat must be used. Seven fixedly coupled, and the inner ring sleeve 128 of the bearing 122 must be tightly coupled with the mandrel 131, and the pusher seat 135 and the jaw seat|32 of the broach mechanism 13 are also closely attached to the inner wall surface of the mandrel 121. Therefore, during the process of loosening and installing the tool, the axial thrust applied to the pusher 135 is transmitted to the mandrel 121' and causes the mandrel 121 and the bearings 122, 122 to be worn. The axial thrust, particularly the bearing 122 adjacent to the cradle 135, is relatively small and less able to withstand such a large thrust. Therefore, the conventional bearings 12, 122 are easily damaged when the conventional spindle device 1 is in use.

參閱圖5、6，當本發明欲由圖3的運轉位置轉換到圖 5的一退刀位置時，首先需使動力源34停止運轉，然後讓液壓油由第一段541進入導液道54内，當液壓油由第一段 541進入時，液壓油會由第二段541及第三段543分別進入第一及第三空間531、533，然後迫使拉爪活塞521及退刀活塞522之前、後活塞部523、526靠合，此時原本位在第二空間532内的液壓油就會由第五段545往第四段5料排出。其中”進入第三空間533的液壓油會將退刀活塞522 往左推，並因此頂推受推座45及拉桿41等元件往左移動 ¥夾爪43對應夾持道311之夾爪退段3丨卩時，受到彈箬圈44的作用，該等夾爪❹ 具10可以被抽離。在同日守間’進入第一空間5S1的液壓油會將拉爪$ 塞521往右頂推，並帶動反扣爪62 一齊往右移動，當反^ 爪62的扣鉤621和反扣座61之徑凸環611相卡抵扣合時會施予心軸3 i及拉刀機構4 _股定位的作用力，此作用；可以克服拉桿41受到頂推時所施予心轴M的左推作用; ，當心軸31不會因為拉桿41車由向移動而被迫左移的過与中’原本夾設在心軸31及固定座2_轴承32、33就; 會承受過大的軸向推力，特別是鄰近退刀機構5之後軸7 33。故本發明改變退刀機構5的構造，同時增設該反㈣構6的設計不僅新穎，更具有避免元件損壞，以及延長）件使用壽命等功效，而具產業上利用性。惟以上所述者，僅為本發明之較佳實施例而已，當; 12 1302481 月匕以此限定本發明實施之範圍’即大凡依本發明申請專利範圍及發明說明内容所作之簡單的等效變化與修飾^皆仍屬本發明專利涵蓋之範圍内。【圖式簡單說明】圖1是一種習知工具機主軸裝置之組合剖視圖，圖中該主軸裝置位在一運轉位置；圖2是一類似圖丨的組合剖視圖，圖中該主輪裝置位在一退刀位置；圖3疋本發明主軸裝置之一較佳實施例的組合剖視圖圖中δ亥主軸裝置位在一運轉位置；圖4是一類似圖3的局部剖視放大圖; 圖5疋-類似圖3的組合剖視圖，圖中該主轴裝置位在一退刀位置；及圖6是一類似圖5的局部剖視放大Referring to Figures 5 and 6, when the present invention is intended to be shifted from the operational position of Figure 3 to a retracted position of Figure 5, first the power source 34 is deactivated and then the hydraulic fluid is directed from the first section 541 into the catheter 54. Inside, when the hydraulic oil enters from the first section 541, the hydraulic oil enters the first and third spaces 531, 533 from the second section 541 and the third section 543, respectively, and then forces the claw piston 521 and the retracting piston 522 before The rear piston portions 523 and 526 are engaged, and the hydraulic oil originally located in the second space 532 is discharged from the fifth segment 545 to the fourth segment 5. The hydraulic oil entering the third space 533 pushes the retracting piston 522 to the left, and thus pushes the components such as the pusher 45 and the pull rod 41 to the left to move to the left. The gripper 43 corresponds to the gripper of the gripping path 311. At 3 ,, by the action of the magazine ring 44, the jaws 10 can be pulled away. In the same day, the hydraulic oil entering the first space 5S1 will push the claw $ 521 to the right. And the anti-claw 62 is moved to the right, and when the hook 621 of the anti-claw 62 and the radial ring 611 of the anti-buckle 61 are engaged and fastened, the mandrel 3 i and the broach mechanism 4 _ The force of the positioning, this effect; can overcome the left push effect of the mandrel M applied when the pull rod 41 is pushed; when the mandrel 31 is not forced to move leftward due to the movement of the pull rod 41 Originally placed on the mandrel 31 and the fixed seat 2_bearings 32, 33; will withstand excessive axial thrust, especially adjacent to the rear retracting mechanism 5 after the shaft 7 33. Therefore, the present invention changes the structure of the retracting mechanism 5, while adding The design of the anti-(4) structure 6 is not only novel, but also has the effect of avoiding component damage and prolonging the service life of the piece, and has industrial advantages. The above is only the preferred embodiment of the present invention, and is intended to be limited to the scope of the invention as defined by the scope of the invention and the description of the invention. Equivalent changes and modifications are still within the scope of the present patent.
