Detailed Description
A plurality of cutting main shafts 21 used for clamping tools are arranged on the circumferential surface of a cutter tower 20 at intervals, the rotating shaft core of each cutting main shaft 21 is consistent with the radial direction of the cutter tower 20, a cutting power output shaft 41 is positioned in the middle of a cavity of the cutter tower 20, the shaft core direction of the cutting power output shaft 41 is consistent with the radial direction of the cutter tower 20, a lug and a groove are mutually embedded and matched with each other by the inner end of the cutting main shaft 21 and one end of the cutting power output shaft 41 when the cutting main shaft 21 is indexed to be in concentric position with the cutting power output shaft 41 along with the cutter tower 20, and the groove wall of the groove and the matching surface on the lug mutually matched with the groove wall are parallel to the rotating surface of the cutter tower 20.
In the above solution, the position of the cutting power output shaft 41 is determined, and when one of the cutting main shafts 21 and the cutting power output shaft 41 are concentric and the end portion between the two forms a mutually-embedded fit of the convex block and the concave groove, the torque can be transmitted, that is, the cutting power output shaft 41 drives the cutting main shaft 21 to rotate, and the cutter on the cutting main shaft 21 performs cutting rotation. The structure of the mutually matched convex block and the groove is beneficial to the clamping of the convex block and the groove and is convenient for the separation of the convex block and the groove, namely, on the premise that the position of the shaft core of the cutting power output shaft 41 is kept fixed, the surface of the shaft core of the cutting main shaft 21 keeps consistent with the shaft core of the cutting power output shaft 41 in the rotation process of the cutter tower 20, in other words, the moving track of the shaft core of the cutting main shaft 21 is that the annular surface always corresponds to the position of the cutting power output shaft 41, and the separation and combination actions of the cutting main shaft 21 and the cutting power output shaft 41 are naturally completed in the transposition process of the cutter tower 20. Particularly, the cutting spindle 21 and the cutting power output shaft 41 are matched in a manner that the convex block and the concave groove formed at the end portions are mutually embedded, so that the radial force is prevented from being exerted between the cutting spindle 21 and the cutting power output shaft, the cutting spindle 21 has no bending moment, the stability of the cutting spindle is ensured, and the machining precision is improved.
A turret connecting sleeve 22 is connected to the basin mouth on the back of the turret 20, the turret connecting sleeve 22 is consistent with the rotation center of the turret 20, and the turret connecting sleeve 22 extends towards the side of the case 10 and forms circumferential rotation and axial limit fit with the case 10. Because the turret connecting sleeve 22 is in a pipe shape, the reliable bending resistance of the turret connecting sleeve ensures the stable posture of the turret 20 in the transposition process, which is also beneficial to the accurate alignment of the cutting main shaft 21 and the cutting power output shaft 41 during tool changing; especially, the stability of the position of the cutting spindle 21 in the cutting process is ensured, and the improvement of the machining precision is guaranteed.
The above scheme requires that the cutting power output shaft 41 is arranged in the middle of the cavity of the turret 20 and fixed in position, so as to realize the clutch fit with the cutting main shaft 21 to transmit the cutting torque, in order to make the cutting power output shaft 41 obtain the rotation torque, the case 10 is connected with the central shaft sleeve 40, the overhanging end of the central shaft sleeve 40 is arranged in the cavity of the turret 20 in a basin shape, the cutting power output shaft 41 is rotatably arranged at the overhanging end of the central shaft sleeve 40, and the cutting power transmission mechanism is connected to the cutting power output shaft 41 through the inner end of the central shaft sleeve 40 and drives the cutting power output shaft 41 to rotate in a cutting manner.
The tubular shape of the central shaft sleeve 40 saves space by arranging the transmission mechanism through the pipe cavity, and utilizes the bending resistance and the torsion resistance of the pipe wall as a fixed supporting unit of the cutting power output shaft 41, so that the position precision of the cutting power output shaft 41 is improved, the phenomenon of shaft core deviation of the cutting power output shaft 41 caused by the reaction force in the machining process is resisted, and the machining precision is further improved.
In order to ensure that the torque is transmitted from the motor to the cutting power output shaft 41, a toothed belt transmission mechanism is adopted because the space interval is large, namely, the cutting motor 45 is arranged on the case 10, a cutting power input shaft belt wheel 42 is arranged at the motor shaft end of the cutting motor 45, the cutting power output shaft 41 is connected with a cutting power output shaft belt wheel 43, and the belt transmission mechanism formed by meshing the cutting power input shaft belt wheel 42, the cutting power output shaft belt wheel 43 and the cutting power toothed belt 44 is the cutting power transmission mechanism.
The cutting power transmission mechanism is arranged by means of the space of the pipe cavity of the central shaft sleeve 40, and the toothed belt not only ensures the advantages of light weight and low cost, but also overcomes the defects of noise and necessary lubrication of gear transmission. Especially, the cutting power is transmitted by adopting a toothed belt, and the pointed position of a convex block or a groove part at the shaft end of the cutting power output shaft 41 can be conveniently and accurately controlled when the cutting power output shaft changes the cutter stop position, so that accurate and timely cutter changing is realized.
To further improve the cutting accuracy, a center bushing bearing 46 is provided between the inner wall of the turret adapter sleeve 22 at the back of the turret 20 and the outer wall of the center bushing 40. Namely, the central shaft sleeve bearing 46 is additionally arranged at the end part of the central shaft sleeve 40 far away from the chassis 10, so that the suspended end of the central shaft sleeve 40 which originally has proper bending resistance is additionally supported by the central shaft sleeve bearing 46, and the deformation disturbance degree of the end where the cutting power output shaft 41 is located is further reduced.
It should be mentioned that the clutch problem of the power system, i.e. the torque transmission and release between the cutting spindle 21 and the cutting power output shaft 41, cannot be effectively solved in the prior art, and three preferable modes provided by the present invention are described below, and the three schemes can timely and accurately realize the clutch of the torque between the cutting spindle 21 and the cutting power output shaft 41.
