摘要： The invention provides a clamping device for machine tools capable of preventing the occurrence of impressions. In a clamping device for machine tools, a tailstock (movable carriage) is provided on a top face of a fixed bed and the tailstock is positioned and fixed with respect to the fixed bed. The tailstock is supported by linear-motion bearings (guides) which are disposed between the tailstock and the fixed bed. Blocks are slidably engaged with rails extending in the travel direction with rollers interposed between them. Further, a recess portion extending in the travel direction is formed in the top surface of the fixed bed. A cylinder mechanism is arranged so that left and right inner walls in the recess portion are pressed by a pair of pistons provided on the undersurface of a headstock.

摘要： A machine tool that comprises a fixed bed, a pair of tool posts mounted on the fixed bed on a side closer to an operator and a carriage mounted on each of the tool posts is disclosed. A headstock is provided on a side of the fixed bed farther from the operator so that a workpiece disposed in the headstock is subjected to a cutting process by moving the carriages and the tool posts relative to the workpiece. The machine tool also includes a headstock base having the headstock disposed thereon. The headstock base is structured and arranged so as to be movable between a workpiece machining position where the workpiece can be machined at a position farther from the operator and a workpiece loading and unloading position where the workpiece can be loaded and unloaded at a position closer to the operator. A chip collecting opening is provided in the fixed bed between the carriages and the headstock when the headstock is positioned in the workpiece machining position. The fixed bed also includes a tunnel formed therein. The tunnel communicates with the chip collecting opening and extends rearwardly away from the operator. In this way, the chips that have fallen into the chip collecting opening can be collected through the tunnel. Thus, this machine tool allows easy workpiece loading and unloading and improves operational efficiency of the machine tool.
摘要翻译：公开了一种机床，其包括固定床，安装在靠近操作者的一侧的固定床上的一对工具柱和安装在每个工具柱上的滑架。在离开操作者的固定床的一侧设置有主轴箱，使得通过相对于工件移动滑架和工具支柱而将设置在主轴箱中的工件进行切割处理。机床还包括具有设置在其上的主轴箱的主轴箱基座。头架底座的结构和布置方式可以在工件加工位置之间移动，在工件加工位置可以在远离操作者的位置加工工件，而工件加载和卸载位置可以在靠近操作员。当主轴箱位于工件加工位置时，在支架和主轴箱之间的固定床中设置有芯片收集开口。固定床还包括形成在其中的隧道。隧道与芯片收集口连通，向后延伸离开操作者。以这种方式，可以通过隧道收集落入芯片收集开口的芯片。因此，该机床允许容易的工件装载和卸载，并提高机床的操作效率。

摘要： A cylinder has a rotating member, a cap, a piston, a collar, two control valves and two check valves. The piston is moveably mounted between the rotating member and the cap. The piston has a flange dividing the inner space between the rotating member and the cap into two chambers. The control valves are attached to the rotating member, respectively communicate with the chambers and respectively communicate with two I/O channels in the collar. The check valves are attached to the rotating member, respectively communicate with the chambers and respectively communicate with the I/O channels in the collar. Accordingly, the thickness of the flange of the piston can be decreased so as to reduce the weight of the cylinder, and the torsion for rotating the cylinder and the load to the axle of the machine are also reduced.
摘要翻译：气缸具有旋转构件，盖，活塞，套环，两个控制阀和两个止回阀。活塞可移动地安装在旋转构件和盖之间。活塞具有将旋转构件和盖之间的内部空间分成两个腔室的凸缘。控制阀连接到旋转构件，分别与室连通，并分别与套环中的两个I / O通道连通。止回阀附接到旋转构件，分别与腔室连通并且分别与套环中的I / O通道连通。因此，可以减小活塞的凸缘的厚度，以减小气缸的重量，并且还减小了将气缸旋转和对机器轴的负载的扭转。

摘要： The present invention consists of a lathe attachment for installation on a portable bandsaw mill, for turning round shafts from wood blocks on the portable bandsaw mill. The lathe attachment has an elongated chassis, a tailstock and a headstock mounted on opposite ends of the chassis for holding and rotating a wood block along the chassis. Bindings are provided to retain the chassis to the cross beams of the portable bandsaw mill. In another aspect of the invention, a number of symmetrical facets are firstly sawed along the wood block prior to turning the wood block. The turning of a round shaft on the bandsaw mill is preferably effected while the alignment of the wood block or shaft makes an acute angle with the direction of movement of the bandsaw head.
