摘要： A ball screw device of a screw axis with a helical groove on its outer circumference for balls to circulate thereon includes a nut with a helical groove on its inner circumference for balls to circulate thereon, a number of balls to circulate in an orbit along the helical groove of the screw axis and the helical groove of the nut, and a tunnel raceway for the balls to circulate unlimitedly. The device has a through-hole formed within the wall of the nut for the balls to circulate from one end of the helical groove to the other end, the through-hole having a guidepath on either end of the helical groove to feed the balls into the tunnel raceway. Means are provided between the helical groove on one end face of the nut and the helical groove on the screw axis to prevent the balls from exiting either helical groove.

摘要： A ball screw mechanism including a screw shaft with a screw groove formed on an external surface, a nut with a screw groove formed on an internal surface, and plural balls held in the grooves. A ball circulation piece is fit in a window portion in the nut and has a circulation groove for circulating the balls. The screw groove of the nut and the circulation groove are machined by moving a tool of a diameter equal to or larger than the diameter of the balls, along the screw groove of the nut so that a step is eliminated at a joint therebetween. The infeed depth of the tool is gradually changed as the tool is moved toward the joint so that boundary lines between a machined surface and a non-machined surface on flanks of the screw groove of the nut extend at an acute angle to one another.

摘要： A clamping system has a clamping device inserted in an installing hole formed in a fixture base, a cylinder unit for operating a clamp and a detection unit for detecting operation positions of the clamp, both of which are formed in the clamping device. In the fixture base, there are formed clamping fluid supplying passages for supplying clamping fluid and detection fluid supplying passages for supplying detection fluid, in which pressure switches are provided. And also, in the clamping device, there are formed detection fluid supply passages and clamping fluid supply passages. When the clamping device is inserted into an installing hole formed in the fixture base, the clamping fluid supplying passages are communicated with clamping fluid supply passages, and also the detection fluid supplying passages is communicated with the detection fluid supply passages through nozzles formed in the cylinder unit. The nozzles are opened and closed due to a movement of a piston formed in the cylinder unit, so that air pressures in the detection fluid supplying passages change, and operation states of the clamp is detected. Further, each of the units is constructed as a unit, so that it is easy to change the setup due to different workpieces.

摘要： In a ball screw mechanism, in order to eliminate a step on a joint between respective one ends of a female screw groove of a nut and a circulation groove of a ball circulation piece, a ball end mill of the diameter equal to or larger than balls is moved along the female screw groove to machine a joint area between the respective one ends of the female screw groove and the circulation groove. During the movement of the ball end mill, the infeed depth of the ball end mill into the machined surface is gradually increased so that an acute angle is formed as the angle formed by the boundary lines between a finished surface and an unfinished surface at both flanks of the female screw groove. Thus, the contact points of each ball on the female screw groove can be prevented from being changed abruptly at the boundary lines between the finished surface and the unfinished surface of the female screw groove, whereby it can be realized to prevent noise and vibration from being generated during the operation of the ball screw mechanism.
摘要翻译：在滚珠丝杠机构中，为了消除螺母的母螺纹槽的各端部与球循环片的循环槽的接合部的台阶，直径等于或大于球的球头铣刀沿着内螺纹槽移动以加工内螺纹槽的各个一端和循环槽之间的接合区域。在球头立铣刀运动期间，球头铣刀进入加工表面的进刀深度逐渐增加，使得锐角形成为由两侧面的精加工表面与未完成表面之间的边界线形成的角度的内螺纹槽。因此，可以防止阴螺纹槽上的每个球的接触点在母螺纹槽的精加工表面与未完成表面之间的边界线处突然变化，从而可以实现防止噪声和振动在滚珠丝杆机构的运转过程中产生。
