| A telescoping die holder apparatus a having a outer covering shell with a tapered rear morse into which a shank is fitted. This shank is associated with a biasing member and is reciprocally mounted to the shell by two retaining pins. Each of the pins extend through the shell into one of the four spaced shank slots that run lengthwise in the shank. Each shank slot is closed at one end and opened at the other end. At their opened ends the slots have outwardly opening chamfer rear ends. One end of the shank allows for a replaceable held die that is used to engage a rotatable work piece stock. At the shell's opposite end, a morse tapered end on the shell fits in the lathe's tail stock. An front optional adaptor can be placed in a large inner diameter opening in an enlarged front end of the shank and is used to accommodate a smaller sized die. The entire telescoping die holder is non-rotatable, including any of its parts, as the lathe turns the retained work piece stock and the stock engages the shank's retained die. | ||||||
| 7 | Button die holder | US78168 | 1987-07-27 | US5003852A | 1991-04-02 | Michael J. Kelly |
| A die holder comprises a die housing and a guide bar. The guide bar is designed to be retained within a Jacob's chuck retained within a lathe tailstock, and the die housing is slidably movable along the guide bar. A button die is retained within the die housing and with the guide bar aligned with the bar stock workpiece held by the lathe headstock, the die housing may be brought into engagement with the workpiece so that the button die engages the same. A user may then grasp the die holder while the headstock and workpiece are rotating so as to effect a cutting of threads. A reverse rotation of the headstock will result in a disengagement of the die holder. | ||||||

| PROBLEM TO BE SOLVED: To perform machining of a machine screw by a lathe at high accuracy and profitably to economy and workability. SOLUTION: A straight shaft part 5 having the non-circular section is provided on a main body 2 to be supported by a tail stock of a lathe by inserting a shank 3 into a holding hole, and a cylindrical head 6 is fitted around the shaft part so as not to be rotated but so as to be slid. A ring-shaped die holder 13 is fixed to a socket part 9 of the cylindrical head 6, and die A supported by the holder is made to bite a rotating workpiece. The cylindrical head 6 is slid on the straight shaft part 5 by thrust to be generated by leading of a screw, accordingly, the tail stock of the lathe is not drawn and moved, and poor machining of the screw caused by poor movement of the tail stock is not generated.

| PURPOSE: A system for automatically processing nuts is provided to simultaneously control each servo motor by supplying the same electric signals to the each servo motor and to reduce troubles by reducing the load in a process with an auxiliary tap for preventing the eccentricity and preventing cutting chips from discharging. CONSTITUTION: A system for automatically processing nuts comprises a shelf device (10), a transfer device (20), and a control box (30). The control box includes a controller (31), a power unit (32), and an uninterrupted power supply module (100). An auxiliary tap for preventing the eccentricity is formed between a tap (21) and a rotary servo motor (22). A ball bearing is installed inside the auxiliary tap with a spring and is moved by a tolerance according to changes of the concentricity. | ||||||

| PURPOSE: A mechanical brake for a hoist having multiple spirals and a processing method of multiple spirals are provided to easily release braking when a hoist work for hoisting freight is stopped due to a power failure. CONSTITUTION: A mechanical brake for a hoist having multiple spirals comprises a drive shaft (50), a boss (51), a mechanical flange (52), a disc member (53), a first brake wheel (55), a ratchet wheel (56), and a second brake wheel (57). The drive shaft is connected to a drive motor. The boss is integrally coupled to the drive shaft. The mechanical flange is coupled to the drive shaft. The disc member is fixed to the mechanical flange and is screwed on the boss to be axially movable along the driving direction of the drive motor. The first brake wheel is coupled to the inner end of a boss part (54) of the disc member to be axially movable. The ratchet wheel is coupled to the outer end of the boss part of the disc member and is rotated by a pole. The second brake wheel is integrally coupled to the boss. First spirals formed on the outer periphery of the boss and second spirals formed on the inner periphery of the disc member form multiple spirals. | ||||||

| PURPOSE: A workpiece screw-machining method utilizing the rotational ratio difference of a main shaft and a spindle is provided to securely process a screw by preventing a backlash and a concentric defect by performing a screwing process by the forward and backward movement of a processing tool. CONSTITUTION: A workpiece screw-machining method utilizing the rotational ratio difference of a main shaft(10) and a spindle(20) is as follows. The main shaft rotates along with the spindles along a same axis in a same direction. Thread machining operates according to rotation rate of a machining tool and a material. The machining tool moves back and forth according to the rotating ratio difference of the processed material and the machining tool. | ||||||
