摘要： A fixed first sleeve and a movable second sleeve are arranged in a center through hole of a main spindle. Balls at the rear end of the second sleeve engage a recessed slope of the first sleeve and a recessed slope of a draw bar, thereby amplifying the urging force of a spring for urging the draw bar upward. Balls at the distal end of the second sleeve hold and pull in the head of the pull stud with the amplified force. The pull stud has an axial through hole and a hole that connects with the through hole and opens sideways. Compressed air passes through these holes, thereby cleaning the respective taper surfaces and end faces of the main spindle and a tool shank. Switching means is used to close the hole that opens sideways, whereby a cutting fluid is allowed to flow through the axial through hole only.

摘要： An automatic tool changing method and an automatic tool changing device for a machine tool with a numerical controller capable of reducing the occurrence of impact due to tool exchange with a simple structure. A turret that rotates about a pivot shaft is provided on an arm and holds multiple tools. A swing cam CS that cooperates with a swing roller provided on the turret is provided on a spindle head. As the spindle head descends the turret rotates due to the action of the swing roller and the cam CS and exchanges tools. In order to lessen the impact that occurs at this time, the velocity of the spindle head is controlled. The ideal swing velocity pattern for the turret is obtained, and from this swing velocity pattern the swing position of the turret at each moment is obtained. From the swing roller and cam CS positions at this position the position of the spindle head 34 is obtained. From the acquired spindle head position the spindle head velocity pattern is obtained, and the spindle head is controlled using this velocity pattern. As a result, an ideal swing pattern can be achieved, and therefore no impact arises.

摘要： A feeder for a machine tool adapted to move a table relative to a saddle by rotation of a motor includes a ball thread nut fixed to the saddle and a ball thread shaft that engages with the ball thread nut in a rotatable manner but is immovable in an axial direction of the ball thread shaft relative to the table. The motor is fixed to the table and the ball thread shaft is coupled to the motor. A sum of a movable distance of the table relative to the saddle and a length of the saddle in the axial direction is shorter than a length of the table in the axial direction. The feeder further includes rails fixed to the table on its surface where the motor is fixed and bearings that are fixed to the saddle and bear the rails.

摘要： An automatic tool changing device capable of cleaning a contact surface of a spindle, which is to be in contact with a tool holder, with a simple structure. The device includes a turret having a plurality of grippers on its outer circumference and holding the tool holder by means of the grippers. At the time of tool change, the grippers grip and pull out the tool holder fixed to the spindle. Rotation of the spindle causes the turret to rotate through a spindle gear, a turret gear, and a decelerating device, to thereby select a tool. At this moment, a coolant is spouted from a nozzle portion of a manifold toward a spindle taper hole in which the tool holder is interfitted and washes the taper hole. Due to the rotation of the spindle, the coolant is spouted onto the whole circumference of the taper hole, and the surface to be in contact with the tool holder is surely washed. Therefore, it is possible to perform the cleaning with a simple structure in which the nozzle portion is arranged near the spindle without machining the spindle and the tool holder.
摘要翻译：一种自动换刀装置，其能够以简单的结构清洁与工具架接触的主轴的接触面。该装置包括在其外圆周上具有多个夹持器并通过夹持器保持工具夹具的转台。在换刀时，夹具抓住并拉出固定在主轴上的工具架。主轴的旋转使转台通过主轴齿轮，转塔齿轮和减速装置旋转，从而选择一个工具。此时，将冷却剂从歧管的喷嘴部分喷射到主轴锥孔，在该主轴锥孔中工具架相互配合并洗涤锥形孔。由于主轴的旋转，冷却剂被喷射到锥形孔的整个圆周上，并且与刀架接触的表面被确实地洗涤。因此，可以以喷嘴部配置在主轴附近的简单结构进行清洗，而不需要加工主轴和工具架。

摘要： A tool changing device and a tool cleaning method capable of surely removing foreign matter such as swarf adhered to tapered portions and/or flange portions of tools, which serve as contact faces to be in contact with a spindle. There is arranged tool cleaning nozzles for spouting coolant on both sides of the spindle in the rotating position of a turret. The tool cleaning nozzle has a position and a posture such that the coolant spouted from the nozzle hits against the tapered portions and/or the flange portions of the tools held by the turret. The coolant is spouted from the tool cleaning nozzle with the rotation of the turret at the time of tool selection. Each time the turret rotates, the tapered portions and/or the flange portions of the tools held by the turret are cleaned by the coolant. Even if foreign matter, such as swarf, is adhered to the standby tools held by the turret, it is possible to surely remove the foreign matter, such as swarf, since the tools are cleaned during the rotation of the turret.
