The working principle of the application is as follows:
when the tool changer 3 is used, firstly, new tools 4 required to be used in machining are all placed into the tool changer 3, when the new tools 4 are placed into the tool changer 3 through the upper tool grooves 3011, firstly, the operation of placing the new tools 4 is required to be selected through the programming control program of the machining center main body 1 when the new tools are placed into the tool changer, so that the lathe component 2 drives the rotating gear of the rotating sleeve 304 to rotate, the rotating sleeve 304 rotates the tool changer turntable 303 after rotation, and when the rotating sleeve rotates, the new tools 4 can accurately fall onto the semicircular baffle ring block 3031 of the tool changer turntable 303 due to rotation according to a certain rule, and the strong magnets of the semicircular baffle ring block 3031 enable the clamping rings of the new tools 4 to fall onto the semicircular baffle ring block 3031 in the falling process, and simultaneously, due to the arrangement of the rotating grooves 3014, the new tools 4 can synchronously rotate when the semicircular baffle ring block 3031 rotates, so that the new tools can translate towards the magnets until the semicircular baffle ring block 3031 cannot move, and if the semicircular baffle ring block 3031 is fixed due to gravity;
when the turning head main body 201 of the lathe component 2 is provided with the original cutter 202 after installation, the machining center main body 1 is controlled by the machining center main body 1 programming control program to perform the cutting operation, when the cutter needs to be replaced or the turning head main body 201 is free of cutters, firstly, the machining center main body 1 programming control program controls the turning head main body 201 to perform cutter returning, when the turning head main body 201 is provided with the original cutter 202, the bottom end of the original cutter 202 is ensured to be flush with the bottom end of the new cutter 4, and when the turning head main body 201 is not provided with the original cutter 202, the turning head main body 201 still reaches a state of being flush with the new cutter 4 when the turning head main body 201 is provided with the original cutter 202, and at the moment, the machining center main body 1 programming control program controls the switching component 5 to perform work;
when the switching assembly 5 works, the machining center main body 1 programming control program firstly controls the telescopic rod 504 to descend, after the telescopic rod 504 is lowered to the limit, the machining center main body 1 programming control program controls the steering motor 5031 of the steering box 503 to rotate so as to drive the transmission bevel gear to rotate, after the transmission bevel gear rotates, the steering box 503 drives the switching rod 501 and the switching ring 502 to rotate around the telescopic rod 504 due to the steering bevel gear 5041 of the telescopic rod 504, after the switching rod 501 rotates, when the switching rings 502 at two ends of the switching rod 501 are respectively located under the rotating head main body 201 and under the cutter lowering groove 3012, and at the same time, the machining center main body 1 programming control program controls the cutter changing turntable 303 to rotate, since the electromagnet of the magnet generating box 3013 is a coil under the condition of no conduction, when the tool changing turntable 303 rotates, the semicircular baffle 3031 of the new tool 4 generates cutting magnet induction line movement when rotating, when the current is about to be the same as the magnet generating box 3013 and is about to be the same horizontal line, the generated current is reduced, and the programming program of the machining center main body 1 controls the machining center main body 1, so that the programming control program can discriminate and limit the rotating angle of the tool changing turntable 303 each time, the tools needing to be replaced are selected, the tools are screened according to the total current amounts of different cutting magnet induction lines under the same rotating angle, when the generated current is the designated current, the tool changing turntable 303 stops rotating when the generated current is about to be close to the magnet generating box 3013, the electromagnet of the magnet generating box 3013 is started to generate suction force to suck the new tool 4 to a position far away from the tool changing turntable 303, therefore, due to inertia, when approaching to the magnetism generating box 3013, the magnetism enters the receiving and changing ring 502 of the receiving and changing assembly 5 right below through gravity and the gap of the lower cutter groove 3012, and at the moment, the programming control program of the machining center main body 1 controls the rotating head main body 201 to perform the cutter-down operation, so that the original cutter 202 of the rotating head main body 201 falls onto the other receiving and changing ring 502, and when the rotating head main body 201 does not have a cutter, the other receiving and changing ring 502 does not need to receive the original cutter 202, so that the cutter-receiving operation is completed;
when the new cutter 4 is received by the switching ring 502, the switching ring 502 rotates 180 degrees, so that the new cutter 4 is located under the rotary head main body 201, the other switching ring 502 is located under the lower cutter groove 3012, at this time, the telescopic rod 504 can carry out return operation, when the new cutter 4 contacts the rotary head main body 201, the telescopic rod 502 is clamped by the rotary head main body 201, when the telescopic rod 504 ascends, the clamping ring of the new cutter 4 is located above the semicircular baffle ring block 3031, and therefore, under the action of strong magnets of the semicircular baffle ring block 3031, a trend of approaching to the rotary disc 303 is generated, at this time, when the telescopic rod 504 descends while carrying out fine rotation, the clamping ring of the original cutter 202 located at the semicircular baffle ring block 3031 contacts the semicircular baffle ring block 3031, at this time, as the original cutter 202 is clamped by the rotary disc 202 to be close to the rotary disc 303, when the telescopic rod 504 descends, the telescopic rod is clamped by the telescopic rod is sucked by the telescopic rod 3031, and the telescopic rod is completely rotated by the rotary sleeve piece 304 after the rotary baffle ring block is rotated by the rotary rod 3011.
