The motor 70 is a permanent magnet synchronous motor, has the advantages of small magnetic loss, small heating value, high power factor, strong overload capacity, high reliability, high processing efficiency and the like, and is beneficial to improving the processing precision and stability of parts. The permanent magnet motor is of a four-lobe structure and comprises a stator 71 and a rotor 72. When three-phase current is supplied, the stator 71 generates a rotating magnetic field. Permanent magnets with fixed magnetic poles are embedded in the rotor 72, and according to the principle that like poles repel each other and opposite poles attract each other, a rotating magnetic field generated in the stator 71 drives the rotor 72 to rotate, so that the rotating speed of the rotor 72 is equal to the rotating speed of the rotating magnetic poles in the stator 71.
The tool shank assembly 80 includes a conventional tool shank 81 and a tool shank 82. When in use, the common cutter handle 81 or the cutter handle 82 is selected according to the processing requirement. When milling, rigid tapping, drilling and other operations are performed, the common tool shank 81 is used, and corresponding tools are clamped on the common tool shank 81. The length of the common knife handle 81 extending out of the lower end surface of the body 611 is longer than the length of the positioning pin 612 extending out of the body 611, so that the positioning pin 612 is prevented from interfering with operation during processing. When turning a product, the turning tool 82 is used, and a turning tool is mounted on the turning tool 82. The common tool shank 81 or the turning tool shank 82 is held by the pull claw 22 and accommodated in the tapered hole. The positioning pin 612 is inserted into the turning tool handle 82, and the height of the positioning pin 612 is adjusted through the adjusting gasket 613, so that the length of the turning tool handle 82 is changed, and the requirements of different machining occasions are met. Because the mounting holes of the body 611 and the machine body 10 are waist-shaped, the positioning angle of the lathe tool handle 82 can be conveniently adjusted after the installation.
The top end assembly 90 includes a connection block 91, an aluminum water jacket 92, and a code wheel 93. An inlet 94 and an outlet 95 are provided on the connection block 91. The connection block 91 is fixed to the upper end of the aluminum water jacket 92, and the aluminum water jacket 92 is fixedly installed to the upper end of the machine body 10. The code wheel 93 is mounted in the machine body 10. The height of the connecting block 91 can be selected according to the requirements of the machine tool. The connecting block 91 has simple structure, small processing difficulty and high operability, and is beneficial to improving the recycling rate of parts. In addition, the connecting block 91 enables the main shaft to meet the machine tool requirement on the original basis without changing the structure of the aluminum water jacket 92, so that the processing cost is saved, and the design error rate is reduced.
Flow passages (not shown) extending in the longitudinal direction are provided along the connection block 91, the aluminum water jacket 92, the bearing housing jacket 46, and the machine body 10. The cooling liquid enters the flow passage from the inlet 94 and directly flows into the second cooling passage 57, and the lower bearing 53 is cooled first. Then the cooling liquid enters the bearing seat jacket 46 after encircling the lower bearing seat 51 for cooling the upper bearing 43; the cooled coolant flows out from the lower end of the bearing housing 46 and flows into the first cooling passage 13 to cool the stator 71. The cooling liquid flows out from the upper end of the first cooling passage 13 after one round of the stator 71, and is discharged through the aluminum water jacket 92 and the outlet 95 of the connection block 91. The cooling process firstly cools the lower bearing 53, takes away heat generated by high-speed operation of the lower bearing 53, ensures that the thermal elongation of the lower end of the main shaft is smaller, and improves the machining precision and stability of parts. Then, the upper bearing 43 is cooled, heat generated by high-speed operation of the upper bearing 43 is taken away, the spindle is prevented from being blocked in the operation process, and the service life of the spindle is prolonged. Finally, the stator 71 is cooled, stabilizing the entire spindle within a reasonable range. In addition, the flow passage, the first cooling passage 13 and the second cooling passage 57 each have a large cross section to increase the cooling capacity.
After assembly is completed, the spindle is run in. The main shaft has a large unbalance amount during running-in due to the structure and processing reasons of all parts of the main shaft. And the number of balance holes 24 which can be provided on the lower end face of the shaft core 23 is small. The balance holes 24 distributed on the lower end surface of the single-leaning shaft core 23 can not meet the dynamic balance requirement of the main shaft. To solve the above disadvantage, in the present utility model, a plurality of screw holes 58 are uniformly distributed on the locknut 56. In addition, the screw hole 58 is also used for realizing the screw fixing connection of the locknut 56 and the connecting seat 63. The gap between the connection holder 63 and the shaft core 23 is in the order of micrometers, thereby ensuring the removability of the connection holder 63 and ensuring that the reassembly does not produce a variation in the unbalance amount.
Along the axial direction of the shaft core 23, the integral structure formed by the interconnection of the cover assembly 60, the lower bearing seat 51, the machine body 10, the shaft core assembly 20 and the upper bearing seat 41 is shorter than other similar main shafts, so that the rigidity of the main shafts is improved, and the stability of product processing is improved. Referring to fig. 3, after the spindle is installed in the machine tool, the distance L between the upper end surface of the flange of the machine body 10 and the lower end surface of the spindle core 23 is short, i.e., the overhanging end of the spindle is short, thereby increasing the overall rigidity of the machine tool.
Compared with the structure of directly locking the stop block 62 to the shaft core 23 by a screw, the stop block 62 is connected to the connecting seat 63 by a socket head cap screw, which has the following advantages: firstly, the baffle 62 is connected to the connecting seat 63 through the hexagon socket head cap screw, the detachability is high, the application scope is wide, the baffle 62 is specially aimed at the tool magazine tool setting and needs the lathe of detaching the front end baffle 62, and is applicable to the tool setting without detaching the main shaft front end baffle 62. The stop block 62 is in micron-sized clearance fit with the shaft core 23, and the stop block 62 is independently subjected to dynamic balance treatment, so that the reinstallation precision is ensured; secondly, the load in the running process is borne by the material strength of the stop block 62, so that the shearing force borne by the connecting screw in the high-speed rotation and instantaneous start-stop process can be greatly reduced, the possibility of shearing the screw due to the centrifugal force of the high-speed rotation and the instantaneous start-stop is reduced, and the safety performance of the main shaft is improved; finally, in order to avoid stress generated during the installation of the stop block 62, a small gap is reserved between the shaft core 23 and the lower end of the stop block 62, so that the problem that the machining precision of the main shaft is affected due to the fact that a large number of iron cuts are embedded in the main shaft during machining is avoided.
The above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present utility model are intended to be within the scope of the present utility model as claimed.
