The working principle of the invention is as follows (see fig. 8 and 9):
(1) when the device is used, the inner curved surface shaft sleeve part 9 is firstly sleeved on the excircle of the fixed body 5 until the inner curved surface shaft sleeve part is contacted with the positioning edge 16;
(2) placing the device on a machine tool, enabling a front tip of the machine tool to abut against a tip hole at the front end of the device, moving a rear tip 10 of the machine tool, enabling the tip to firstly penetrate through a tip taper hole 31 of a pushing sleeve along with the movement of the rear tip, and after the two contact, enabling the tip to push the pushing sleeve forwards along the axial direction until the rear tip 10 completely abuts against the tip hole at the rear end of the device;
(3) as the rear center pushes the propelling sleeve 1 forward, the large spring 8 in the propelling sleeve is forced to compress so as to push the transmission taper sleeve 2 to move forward. Because the elasticity of the small spring 7 is smaller than that of the large spring 8, the small spring 7 is compressed when the transmission taper sleeve 2 moves forwards, and the half-moon-shaped tension block 4 is pushed outwards along the radial direction under the action of the conical surface of the transmission taper sleeve until the inner curved surface shaft sleeve part 9 is clamped;
(4) starting the machine, and carrying out corresponding surface finish machining on the part by the machine driving device;
(5) after the machining is finished, one hand holds the device, and the other hand withdraws the rear center of the machine tool from the center hole of the device. When the rear center gradually withdraws from the center hole, the pushing sleeve 1 is pushed out together under the action of the large spring 8, and the large spring 8 stops acting until the inner annular flange 32 of the pushing sleeve 1 contacts with the outer annular flange 26 of the transmission taper sleeve 2;
(6) when the rear center of the machine tool exits from a center hole at the rear end of the device and moves backwards together with the pushing sleeve 1, the elastic force of the small spring 7 pushes the transmission taper sleeve 2 to move axially, and the limiting pin 27 on the transmission taper sleeve 2 is in sliding fit with the limiting groove 22 of the mandrel 6, so that when the transmission taper sleeve moves to the state that the limiting pin 27 is in contact with the limiting groove 22, the axial movement is automatically stopped, and the transmission taper sleeve is ensured to be always on the mandrel 6;
(7) when the transmission taper sleeve 2 moves along the axial direction, the conical surface of the transmission taper sleeve gradually separates from the half-moon-shaped tensioning block 4, the half-moon-shaped tensioning block 4 releases the clamping force on the inner curved surface shaft sleeve part 9, and the clamping device and the inner curved surface shaft sleeve part can be taken down;
(8) when the conical surface of the transmission taper sleeve 2 is separated from the contact with the half-moon-shaped tensioning blocks 4, the six half-moon-shaped tensioning blocks 4 can fall down along the gravity direction, and the spring ring 3 always penetrates through the limiting groove 25 of the half-moon-shaped tensioning block and is kept in the annular groove 17 of the fixing body 5, so that the half-moon-shaped tensioning block can be limited in the semicircular groove of the fixing body 5, and the integrity of the clamping device is kept.
The technical means disclosed in the invention scheme are not limited to the technical means disclosed in the above embodiments, but also include the technical scheme formed by any combination of the above technical features.
