The M336832 [Embodiment] The aforementioned and other technical content, features and effects 'in one of the following reference drawings The detailed description of the preferred embodiment will be clearly shown. Referring to Figures 3 to 6, the preferred embodiment of the power turret of the novel CNC lathe is assembled with a CNC lathe-machine (not shown). And can be moved back and forth, left and right, up and down by a position adjustment mechanism disposed on the machine, and the power turret is used to clamp a plurality of tools 2 (Fig. 3 only shows the _ branch 2) The turret is moved by the position adjustment mechanism to perform drilling, milling, etc. processing of the workpiece (not shown). Since the other components of the CNC lathe are not the focus of this new modification, they are not described here. The following is only for the power turret of the present invention. The power turret of this embodiment comprises: a base 3' - a motor 4 mounted on the top of the base 3, a transmission unit 5 rotated by the motor 4, A main knife unit 6 that is driven by the transmission unit 5, three sub-tool units 7 spaced apart from the main knife and unit 6, and three transmission helical gears 8 that connect the barrel units 6, 7. The base 3 includes two first and right spaced apart side walls 31, two a front and rear spaced second side wall 32, a top wall 33 at the top of the first and second side walls 31, 32, and a peripheral wall 34 extending vertically upward from the right side of the top wall 33. The motor 4 includes a body 41 And a motor output shaft 42 projecting from the main body μ to the right side of the peripheral wall 34. The transmission unit 5 includes a transmission wheel 51 having a height ρ below the motor output shaft 42, and a coupling of the transmission wheel 51 and The motor output shaft 42 of the belt 52. M336832 The main tool barrel unit 6 includes a first-side active shaft 架 which is extended to the left and right of the base 3 and is rotatably mounted on the first side wall 31 of the base 3. The first cutter cylinder 62 on the left side of the first drive shaft 61 is sleeved on a main helical gear Μ and a first helical gear 64 of the first drive shaft 61, and extends forward and backward to be erected a first driven shaft 65 of the second side wall 32, a second cutter 66 disposed at the front end of the first driven shaft 65 and located at the front side of the second side wall 32, and a set of the first slave A second spiral inclined wheel 67 that is at the rear end of the moving shaft 65 and is in contact with the first helical helical gear 64. Wherein the right end of the first-actuating shaft & is provided for the transmission wheel η-an active shaft 61 to be driven by the transmission wheel 51 to rotate in conjunction. = Brother 1, the cutters 62, 66 have - the tool for the cutter 2 to reach the Mi Mi. Of course, the main tool unit 6 further includes a plurality of bearings and the like: two: since the members are not the improvement points of the present invention, the structure of each member of the unit 7 is not the same as the main unit 6; ^ is symmetrically disposed on the main shaft of the main cutter cylinder "the same as the t-unit 7 includes: - a second drive shaft 71 extending left and right and spaced apart from the first steam 72 (four), - a third knife on the left side = first: Γ The second "second material helical gear 74, - front and rear extension to correspond: first - slave town - set in the second slave =: the fourth knife with 76' and _ and the third spiral oblique helical gear 77 . The second of the fourth embodiment of the transmission pin 8 is mounted above and below the M336832 main helical gear 63, and both mesh with the main helical gear 63 and the secondary helical gear 73. The other transmission helical gear 8 is sprayed between the sub-spiral gears 73 of the lower = two sub-cylinder units 7. In the present invention, the main motor unit 6 is first actuated by the motor 4. The motor output shaft 42 is driven to rotate, and the transmission wheel 51 is driven to rotate via a belt 52. The transmission wheel 51 drives the first drive shaft 61 to green: the body axis rotates 'to link the first knife barrel 62, the main helical gear 63, The second helical helical gear 64 rotates, and the second helical helical gear 67 is driven by the first helical helical gear 64 and the second helical helical gear 67. The second helical helical gear 67 is driven to drive the younger-driven shaft 65 and the second cutter 66. Turn. Therefore, the two main blades 62, 66 of the main body can be driven to drive the cutter 2 to rotate. The main knife unit 6 is rotated by the 偻 缓 缓 , , , , , , , 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前 前The gear 8 then transmits the power to the auxiliary helical gear 73 to rotate the movable 71 about its own axis, so that the key causes the second drive shaft to drive the third and fourth helical helical gears 74, 77 to drive the first knife to rotate simultaneously. , at the bottom of the sub-cutter unit 7, Β: knife, Μ rotation. Similarly, the gear 8 transmits power to operate. From the lowermost transmission screw, as can be seen from the above description, the present invention can be driven by the motor 4 wheel 51 to drive the main "52 and the transmission between the two by the transmission helical gear, and the cutter unit 6, 7 is not seen. Know, therefore, this courier power and linkage, the above-mentioned transmission 5 and this new type is provided _ tower, and this new type uses the main helical teeth 3, the innovative structure of the power knife special ··· the oblique gear to pass 9 M336832 Advantages of using the oblique gear 4: The three teeth can be meshed between the two gears at a time. Compared with the normal use of the spur gear, the spur gear can only mesh with one tooth at a time, so the new type of diagonal gear transmission can provide a larger The above is only the preferred embodiment of the present invention, and it is not possible to limit the scope of the present invention to the extent that it is simple to do according to the scope of the novel application and the novel description.
