Description of the invention: [Technical field to which the invention pertains] There is a description of a processing tool, in particular, a turntable device which can effectively save manufacturing costs. The general NC machine tool usually has the function of moving χ, γ, ζ, and the knives can use the two-axis movement of the heart-shaped temple to use the two-axis movement to accurately reach the cutting point and perform the cutting action. However, the above three-axis direction is caused by: a linear movement relationship, and it is impossible to make a circle (four degrees). The NC tool is usually mounted with a rotary device called a fourth axis, thereby enabling the workpiece to be- Cutting operations such as indexing, rounding: circumferential surfaces. ° Tea reading Figure 1 'The conventional fourth-axis rotary disk device 10 includes an active unit η and a driven unit 12, the active unit 11± having a drive shaft (1) and a roll disposed on the drive shaft (1) a tooth cam ι 2 is formed, and a motor (not shown) is connected to the outer end of the driving shaft (1) as a driving source, and the roller 2 cam m is concavely provided with a thread portion ιΐ2ι having a predetermined pitch, which is early π 12 mainly has a driven shaft 121 and a connecting drive plate 122 disposed on the driven shaft (2). The driven shaft (2) is perpendicular to the driving shaft U1, and the driven shaft 121 extends to the outer end. The rotating disc (not shown) can be mounted and fixed to the workpiece. The driving disc 122 is integrally coupled with the driven shaft i2i. The outer circumference of the annular array shaft is provided with a plurality of rollers 1221, and the roller coffee can be wall-mounted. On the threaded portion 1121, when the #active shaft iu starts to operate, the hobbing cam m can drive the drive disc 122 to rotate by a predetermined angle by the screw portion 1121, so that the workpiece mounted on the outer rotary disc can be rotated. The workpiece can be rotated. There is still a great problem to be solved in use. The above-mentioned active unit 11 is provided with a hobbing cam 112 to produce a fine g - 1n cutting person i V as early as 12, in conjunction with the hobbing cam to take a large bucket point in the wheel 1221 The contact thread portion (10) is poor:: two parts ^ weeks = liter rotation precision, and by the force strength "", the wheel 12 is quite special in shape, in order to match the contour of the disk wheel to eliminate the speed difference, hobbing A ^ part 1121 shape is two West a few ^ 丄 丄 mother thread open ... to do special chamfering, this special mechanism to do, so the whole 栌 姿 几 Π Π / 2 /, this in # Ί 3 0 ^ ^ ^ spoke 1 12 The cost of the construction is quite expensive, so that the workpiece of the rotary disk device 10 is made to be effectively reduced. The turntable device 10 is used when the cow is to be cut, because the roll-to-roll is too iu2, and when the workpiece is to be re-cut = 2 to provide the brakes, the product will be produced. It is often unable to withstand the heavy cutting torque and the displacement of the seat is caused, resulting in the accuracy of the workpiece device U. Therefore, the rotary disk needs to use a large motor to ''0 煞 braking force to stop' and must be large oil body', to cope with heavy cutting The torque power, however, will increase the cost and increase the relative cost. In addition, the method and the volume of the hobbing cam 122 are installed, and the teeth are rotated. In order to have the outer disk for the drive plate, the outer casing of the turntable 2 is necessary to extend in the horizontal direction 6 1296223 = The limited space application is quite unfavorable. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a Nc fourth-axis rotary disk device which can greatly increase the load-carrying torque and effectively reduce the manufacturing cost.
