Description
本新型是有關於一種工具機的配重,特別是指一種流體靜壓缸。The present invention relates to a counterweight of a machine tool, in particular to a hydrostatic cylinder.
工具機的垂直軸為了減輕馬達的負荷,一般會使用配重機構,最簡單的配重機構就是使用配重塊,例如中華民國證書號第M363350號專利案,是在一機頭頂部連接有一連動元件,該連動元件繞過一機柱頂部後又與一配重塊相連接。這種配重設計由於機頭質量加倍,所以動態特性較差。The vertical axis of the machine tool generally uses a weight mechanism to reduce the load on the motor. The simplest weight mechanism uses a weight. For example, the Republic of China Certificate No. M363350 patent is a linkage at the top of a machine head. The component is connected to a weight by bypassing the top of a column. This weight design is poor in dynamic characteristics due to the doubled head quality.
另一種常用的配重機構就是使用油壓缸,例如中華民國證書號第M317895號專利案,是在一工作頭與一機柱頂部之間設置有一配重缸,該配重缸的活塞與活塞桿都需要設置密封零件,由於密封零件與缸體、活塞桿須緊密配合,故活塞和活塞桿移動時會產生相當大的摩擦力,此摩擦力除了影響動態特性外,也會影響微進量,所以無法達成精密微進給之目的。Another commonly used weighting mechanism is the use of a hydraulic cylinder, such as the Republic of China Certificate No. M317895, which is provided with a counterweight cylinder between the working head and the top of a column, the piston and piston of the counterweight cylinder.

因此,本新型之目的,即在提供一種可減少摩擦、動態特性佳且可達到精密微進給之流體靜壓缸。Therefore, the object of the present invention is to provide a hydrostatic cylinder which can reduce friction, has good dynamic characteristics and can achieve precise micro-feeding.

再如圖1至圖3所示,當該活塞單元20上昇時,壓力流體由該進給流道15導入至該活塞腔11的第一區域111中,可推動該活塞單元20朝設置有該引出流道16的方向移動,同時,壓力流體(本實施例可為壓力油)會流經該導流孔215,並利用該等分流道216的設置,壓力流體通過該等節流部22、外側段202而流至該等壓力槽217,對應該等壓力槽217的活塞單元20與該缸體10之間會形成一流體靜壓軸承。同時,該活塞21的外環面213與該缸壁12之間仍然存有可相對滑動的間隙,該外環面213與該缸壁12之間的間隙中會有壓力流體滲入並會形成一油膜,利用該等流體靜壓軸承與該油膜的作用,可使得該活塞21與該缸體10相對運動時無摩擦力產生,動態特性較佳,利用該流體靜壓缸的設置可達到平衡配重目的,且可減輕工具機用於驅動一滾珠螺桿(圖未示)的一驅動馬達的負載。且該等壓力槽217的壓力流體會再匯集至該等集油溝214,最後再利用該等匯流道218引流至該第二區域112(該第二區域112中的流體呈常壓),最後由該引出流道16排出,以利循環再利用。As shown in FIG. 1 to FIG. 3, when the piston unit 20 is raised, pressure fluid is introduced into the first region 111 of the piston chamber 11 by the feed flow passage 15, and the piston unit 20 can be pushed toward the piston unit 20. The direction of the flow path 16 is taken out, and at the same time, the pressure fluid (which may be pressurized oil in the embodiment) flows through the flow guiding hole 215, and the pressure fluid passes through the throttling portions 22 by the arrangement of the equal dividing passages 216. The outer section 202 flows to the pressure grooves 217, and a hydrostatic bearing is formed between the piston unit 20 corresponding to the pressure groove 217 and the cylinder 10. At the same time, there is still a relatively slidable gap between the outer ring surface 213 of the piston 21 and the cylinder wall 12. A pressure fluid infiltrates into the gap between the outer ring surface 213 and the cylinder wall 12 and forms a The oil film, by the action of the hydrostatic bearing and the oil film, can make the piston 21 and the cylinder 10 move without friction, and the dynamic characteristics are better, and the arrangement of the hydrostatic cylinder can be balanced. The purpose of the utility model is to reduce the load of a driving motor for driving a ball screw (not shown). The pressure fluids of the pressure tanks 217 are collected again into the oil collection grooves 214, and finally the second flow paths 218 are drained to the second region 112 (the fluid in the second region 112 is at normal pressure), and finally It is discharged from the take-out flow path 16 to facilitate recycling.
當該活塞單元20下降且朝向設置有該進給流道15的方向移動,並利用該活塞21擠壓該第一區域111中的壓力流體,也會使得壓力流體再由該導流孔215引入,也會在對應該等壓力槽217的活塞單元20與該缸體10之間會形成流體靜壓軸承,因此,該活塞單元20相對於該缸體10產生雙向移動時,都可產生較佳的動態特性。When the piston unit 20 is lowered and moved toward the direction in which the feed flow path 15 is provided, and the pressure fluid in the first region 111 is pressed by the piston 21, the pressure fluid is again introduced by the flow guiding hole 215. Also, a hydrostatic bearing is formed between the piston unit 20 corresponding to the pressure groove 217 and the cylinder block 10. Therefore, when the piston unit 20 is moved bidirectionally with respect to the cylinder block 10, it is preferable to produce a hydrostatic bearing. Dynamic characteristics.

The bearing 50 is nested with the bearing housing 40. The bearing housing 40 is fixed to the upper support ring 32. The upper support ring 32 is locked to the connecting post 219 of the piston 21 through the locking member 34. The movable rod 60 can be The weight of the machine tool head is supported by the piston unit 20.
該上支撐環32與該下支撐環31之間的鋼珠33可以吸收該活塞桿60的軸向相對於該軸線L所產生的徑向偏差。利用該軸承座40的凹球面42與該球狀軸承50的凸球面51的配合,可吸收該流體靜壓缸之軸線L與該活塞桿60軸向的角度偏差,如此可改善流體靜壓缸的組裝性,並提昇該活塞21移動的順暢性。The steel ball 33 between the upper support ring 32 and the lower support ring 31 can absorb the radial deviation of the axial direction of the piston rod 60 with respect to the axis L. By the cooperation of the concave spherical surface 42 of the bearing housing 40 and the convex spherical surface 51 of the spherical bearing 50, the axial deviation of the axis L of the hydrostatic cylinder from the axial direction of the piston rod 60 can be absorbed, so that the hydrostatic cylinder can be improved. The assembly is improved and the smoothness of the movement of the piston 21 is improved.
