摘要： PURPOSE: To prevent a guide rail and drive body of a door from projecting out of both sides of a machine tool by providing the drive body to move a door body along the guide rail on a movable body or the guide rail. CONSTITUTION: During the cutting work of a wheel W, a head stock 2 is located in the advance position so that a piston rod 10a of a cylinder 10 is extended to have an end of a door body abutting against a stopper or the like and close the left and right door bodies 7, 7. When the working of the wheel W is completed between spindles 3, 3, the spindles 3, 3 retreat to the head stock 2 side to release the chucking of the wheel W, while the cylinder 10 is driven to shrink back the piston rod 10a and slide the door body 7 along a guide rail 8 in the opening direction. Thus, the door body 7 retreats and an opening part of a splash cover 6 is fully opened.

摘要： PURPOSE: To make both the centers of a spindle and a wheel by lowering a tool rest after maing it synchronize with the ascent of the wheel by means of a lifter unit, stopping the movements of the lifter unit and the tool rest at a position where a detecting means has detected its contact with the wheel, and compensating a traveling position of the lifter unit according the outside dimensions. CONSTITUTION: A contact member attached to a tool rest 5 is outputted by a proximity switch at a time when it has contacted with a flange part of a machined wheel 2, and thereby a synchronous lifting motion between a lifter unit 8 and this tool rest 5 is stopped. Next, diametral measurement of the machined wheel 2 is operated by an amount of travel in the tool rest 5 or lifter unit 8, and in consequence of this operation, a fact of whether a diameter of the machined wheel 2 is larger than the reference size or not is judged. If a compensation value is outputted according to this judgment, the lifter unit 8 is made to go up on the basis of this compensation value, and then the center of this machined wheel 2 is accorded with that of a spindle 3a, and thus a center detecting process is over.

摘要： PURPOSE:To make easy indexing of an attachment by detaining the clamping jaw of a clamp movable member with the clamped jaw of a clamp ring by a pin groove and a pin, fixing it, and making the clamp ring rotatable relative to an attachment case. CONSTITUTION:When an attachment is to be indexed, a pin 41 of a clamp ring 40 is inserted in a pin groove 44 of a clamp movable member 36 and coupled fast, while the clamp 40 is held rotatable relative to an attachment case 22. Therefore, a clamping pawl 37 in detention with a clamped jaw 39 of the clamp ring 40 will not be disengaged even though the attachment 22 revolves to any angle, and there is no fear of generation of obstruction in clamping thereafter. As a pin 42 for preventing turning together of the clamp movable member 36 is detained with a pin groove 43 in a spindle head 1, the clamp movable member 36 is being prevented from rotating.

摘要： PURPOSE:To improve the working efficiency and safety of a machine tool by changing automatically a cutter head set with a tool in a stocker for a cutter head on a chuck, and machining a workpiece through the relative linear motion thereof from the chuck. CONSTITUTION:Once the shape and the machining process of a workpiece 4 has been decided, a cutter head 3 is drawn out from a stocker by an automatic cutter head exchanger and inserted in a chuck 1. Then,a push rod 216 for a main spindle 2 advances and the forward end of the workpiece 4 comes in contact with a flange plate 222 for the support of the workpiece 4. Thereafter, the oil passage 105 of a cylinder block 103 is fed with pressurized oil, thereby moving a piston part 111 to the left side and a master jaw 109 toward the center. As a result, a piston head 3 is held and secured by a retaining part 109b. On the other had, once a piston 113 has been pushed down to insert a pin in a long-grooved cam 305a at a proper position,and the cutter head 3 is made to turn by the main spindle 2, the workpiece 4 is held by a centering chuck jaw 5 and fed into a space within the internal cylinder 101 of the chuck 1 for machining to a predetermined outer diameter.

摘要： PROBLEM TO BE SOLVED: To provide a wheel supporting method of a car wheel lathe capable of automatically supporting the center of a wheel without applying an unreasonable force to the wheel even when a wheel with different axle lengths and a wheel with a same axle length are mixed, and the car wheel lathe. SOLUTION: The wheel supporting method of the car wheel lathe comprises two main spindle blocks for rotatably supporting respective main spindles, a wheel supporting member for supporting the wheel from both sides, a driving means for the wheel supporting member for back and forth moving each wheel supporting member to each main spindle, and turns a pair of wheel pairs of the wheel. The wheel supporting method comprises a first procedure for determining whether lengths of an axle part between the end surface of the wheel parts of the wheel and both ends of the wheel axle are different from each other, and a second procedure for controlling starting, stopping, or moving speed of the driving means so that the wheel supporting member simultaneously or substantially simultaneously presses and supports both ends of the wheel axle when it is determined that there is a difference in the first procedure.

摘要： PROBLEM TO BE SOLVED: To smoothly delivery a wheel to a carry-out rail without assistance so as to improve the mechanical operation rate by moving a mover or a push member between the retreat position where the push member does not interfere with a wheel and the operating position where it can come into contact therewith, and driving a driving means after the worked wheel is placed in a transport guide part. SOLUTION: After the end of working a wheel W, a transport guide member 2 is reverse-acted to place the wheel substantially horizontally on a bed 1. Since a slider 30 is positioned in a designated position of the other end of a sliding part 6 by a stopper 10, engagement clicks 35, 36 and the slider 30 smoothly engage with each other to enable movement of the slider 30. The wheel W is lowered onto a transport rail 2a by a lifter device and placed. Subsequently, a cylinder 12 is driven to degenerate a piston rod 12a, thereby making the stopper 10 freely turn to the other side, and a cylinder 16 of a first kick-out means 15 is driven to elongate a piston rod 16a, whereby the tread of the wheel W is pressed by a kick-out plate 18 to discharge the wheel from a first position A.
