Embodiment Construction
[0022] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0023] Such as figure 1 with figure 2 As shown, the turning tooling of the cylindrical part includes a first mandrel 1, a screw 3 whose first end is detachably connected to the first mandrel 1, a first nut 7 threadedly connected to the first end of the screw 3, and a screw 3 connected to the first end of the screw 3. 3 The second mandrel 6 detachably connected to the other end, the first bulging block 2 connected to the first mandrel 1, the second bulging block 5 connected to the second mandrel 6; the center of the first mandrel 1 has An axial through hole for the screw rod 3 to pass through. The end of the first mandrel 1 near the first nut 7 has a clamping position 8 and a first calibration reference position 9. The side of the first mandrel 1 is a conical surface, and the end away from the clamping position 8 The diameter is smaller ...

The invention discloses a method and a tool of turning a cylindrical part. The tool comprises a first core shaft (1), a screw rod (3), a first nut (7), a second core shaft (6), a first bulging block (2) and a second bulging block (5), wherein the first core shaft is provided with an axial through hole, a clamping position (8) and a first correcting reference position (9), the second core shaft isprovided with an axial threaded blind hole, and a central hole (11) and a second correcting reference position (12); a clamping and positioning process comprises the following steps that the second bulging block is attached to the inner hole of the part, a second positioning spigot is used for clamping the end face of the part, the second core shaft is plugged into the inner ring of the second bulging block, and the threaded rod is connected with the second core shaft; the first bulging block is attached to the inner hole of the part, a first positioning spigot is used for clamping the end face of the part, the first core shaft is plugged into the inner ring of the first bulging block, and the threaded rod is connected with the first nut; and the first nut is screwed, and the clamping position and the central hole are connected with a lathe, and when the position corrected, machining is carried out on the outer face of the part.
Description
technical field [0001] The invention relates to the technical field of machining, in particular to a tooling for clamping and alignment of cylindrical parts in turning; the invention also relates to a method for turning of cylindrical parts. Background technique [0002] Turning cylindrical parts, the general clamping method is to install a four-jaw chuck on the spindle of the lathe, and the four claws of the chuck grasp the outer circular surface of one end of the cylindrical part, so that the cylindrical material can rotate with the four-jaw chuck. According to the length and shape of the cylindrical parts, install plugs, mandrels or tires on the tailstock of the lathe. The outer circle of the plugs, mandrels, and tires and the inner circle of the other end of the cylindrical parts are clearance fit, which can support Hold the other end of the cylindrical part and turn it with the part. When the coaxiality of the inner and outer circles of the cylindrical part to be proce...
