The working principle is as follows: the automatic transposition device for lathe machining is firstly installed at a use position and used according to the following modes:

according to fig. 1-8, the path of movement of the support base 3, and therefore of the knives on the cutterhead 5, is first set by conventional programming;

in the programming process, the moving distance of the supporting base 3 is prolonged during transposition, and then in the moving process of the supporting base 3, automatic transposition is carried out through the following processes:

when the position needs to be changed, the cutter is gradually separated from the object, and the moving distance of the supporting base 3 is prolonged during the position changing, so that the supporting base 3 can gradually move towards the limiting block 2, and the limiting block 2 extrudes the connecting rod 11;

when the connecting rod 11 is pressed, the supporting disk 10 is synchronously pressed, so that the supporting disk 10 and the cutter head 5 are close to each other, the supporting rod 14 extends into the sleeve 12, and the spring 13 is compressed;

while the supporting disc 10 and the cutter disc 5 are close to each other, the twist threaded rod 15 gradually approaches the twist threaded hole 16 until the twist threaded rod contacts the twist threaded hole;

in the process that the twist threaded rod 15 gradually approaches the twist threaded hole 16 to be contacted, the positioning tooth block 9 also moves towards the inside of the cutter head 5, so that the limit teeth 8 and the teeth on the positioning tooth block 9 are completely staggered, and the connection between the limit teeth and the positioning tooth block is disconnected;

then, the supporting disk 10 and the cutter head 5 are continuously close to each other, the twisted threaded rod 15 can be in threaded connection with the twisted threaded hole 16 under the action of the torsion spring 18, and the rotating shaft 17 provided with the twisted threaded hole 16 can rotate through the threaded connection of the twisted threaded rod and the twisted threaded hole;

when the rotating shaft 17 rotates, the cutter head 5 can rotate through a one-way transmission structure formed by the spring groove 21, the spring piece 22, the ratchet 23, the pawl 24 and the transmission groove 25, and the relative positioning tooth block 9 moves in the displacement groove 7;

the purpose of transposition can be achieved through rotation of the cutter head 5, and then the supporting base 3 moves according to a programmed moving track, so that the limiting block 2 is gradually separated from the connecting rod 11;

in the process that the limiting block 2 is separated from the connecting rod 11, the supporting disc 10 and the cutter disc 5 can be gradually far away from each other through the resetting of the spring 13, and then resetting is carried out;

due to the one-way transmission structure formed by the spring groove 21, the spring piece 22, the ratchet 23, the pawl 24 and the transmission groove 25, the cutter head 5 can be prevented from being driven to rotate when the rotating shaft 17 rotates, one end of the positioning tooth block 9 can move in the cutter head 5 in the process of keeping away from the supporting disc 10 and the cutter head 5, teeth on the positioning tooth block are meshed with the limiting teeth 8 at the position at the moment, the cutter head 5 can be prevented from rotating, the transposition stability can be ensured, the stability of a cutter in the use process is ensured, and the content which is not described in detail in the specification belongs to the prior art known by professionals in the field.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
