[0021] Referring to Figure 3 and Figure 5 ​The taking material assembly comprises a first electric telescopic rod 11 fixedly connected at the bottom of the adjusting block 10, a horizontal plate 12 fixedly connected at the bottom of the first electric telescopic rod 11, a second electric telescopic rod 13 fixedly connected at one side edge of the horizontal plate 12, a first clamping plate 14 fixedly connected at the output end of the second electric telescopic rod 13, and a second clamping plate 15 fixedly connected at the bottom of the horizontal plate 12 and located at the edge away from the second electric telescopic rod 13. The first electric telescopic rod 11 is started to drive the horizontal plate 12 to slowly descend, so that the material is located between the first clamping plate 14 and the second clamping plate 15. Then, the second electric telescopic rod 13 is started to drive the first clamping plate 14 to move towards the material. Finally, the material is clamped and fixed by the first clamping plate 14 and the second clamping plate 15. When the material rotates one hundred and eighty degrees to reach the numerical control grinding machine, the second electric telescopic rod 13 is retracted to drive the first clamping plate 14 to separate from the material, so as to realize the discharging operation. At this time, the material can be fixed to another taking material assembly. Thus, the manpower cost and the time cost are saved.

[0022] With reference to Figure 5 , the bottom end of the rotating shaft 5 is rotationally connected with the bottom inner wall of the control box 1, and the rotating shaft 5 can rotate in the interior of the control box 1.

[0023] With reference to Figure 1 and Figure 2 , the front side wall of the control box 1 is hingedly connected with a box door 16, the front side wall of the box door 16 is hingedly connected with a slot, the interior of the slot, which is formed in the front side wall of the box door 16, is installed with an observation window 17. Through the observation window 17, the working state of the stepping motor 2 in the interior of the control box 1 can be detected in real time. The box door 16 can be opened to overhaul the stepping motor 2. The rear wall of the control box 1 is provided with a plurality of heat dissipation holes, so as to facilitate the heat dissipation operation of the stepping motor 2.

[0024] With reference to Figure 2 , the bottom of the control box 1 is installed with a base 18, and the base 18 can provide support for the control box 1.

[0025] The implementation principle of the material taking device for the numerical control grinding machine is that the material taking device fixes the material on one side and transports it to the numerical control grinding machine on the other side. The servo motor 8, the first electric telescopic rod 11 and the second electric telescopic rod 13 are electrically connected with an external power supply through switches. The servo motor 8 is preferably of HBS57 type. The servo motor 8 is started through the switch. The servo motor 8 works to drive the screw rod 9 to rotate. The rotation of the screw rod 9 drives the adjusting block 10 outside the screw rod 9 to slide. The top of the adjusting block 10 is tightly combined with the inner wall of the web of the U-shaped plate 7, so that the rotation deviation of the adjusting block 10 during the movement outside the screw rod 9 can be avoided. The material taking assembly moves outside the screw rod 9 following the adjusting block 10 to realize the taking of the material. The first electric telescopic rod 11 and the second electric telescopic rod 13 are preferably of LX600 type. The first electric telescopic rod 11 is started through the switch to drive the horizontal plate 12 to slowly descend, so that the material is positioned between the first clamping plate 14 and the second clamping plate 15. Then, the second electric telescopic rod 13 is started through the switch to drive the first clamping plate 14 to move towards the material. Finally, the material is clamped and fixed by the first clamping plate 14 and the second clamping plate 15. The stepping motor 2 is connected with an external stepping motor controller. The stepping motor controller is an electronic product capable of emitting uniform pulse signals. The signals emitted by the stepping motor controller are converted into strong current signals required by the stepping motor 2 by the external stepping motor driver after entering the stepping motor driver, so as to drive the stepping motor 2 to operate. The stepping motor 2 is preferably of SC42 type. The stepping motor controller is preferably of TPC8-8TD type. The stepping motor driver is preferably of XDL-542 type. The stepping motor 2 is started. The stepping motor 2 works to drive the driving gear 3 to rotate, so as to drive the driven gear 4 to rotate. The diameter of the driving gear 3 is smaller than that of the driven gear 4. Therefore, the high-speed and low-torque rotation of the driving gear 3 drives the low-speed and high-torque rotation of the driven gear 4. The low-speed and high-torque rotation of the driven gear 4 drives the rotation of the rotating shaft 5 and the adjusting beam 6, so as to increase the stability of the adjusting beam 6 in driving the U-shaped plate 7 and the material taking assembly to rotate. When the material rotates one hundred and eighty degrees to reach the numerical control grinding machine, the second electric telescopic rod 13 is retracted to drive the first clamping plate 14 to separate from the material, so as to realize the unloading operation. At this time, the material can be fixed to another material taking assembly. The operation is repeated, so as to save the labor cost and the time cost. The working state of the stepping motor 2 in the control box 1 can be detected in real time through the observation window 17. The control box 1 is provided with a plurality of heat dissipation holes in the rear wall, so as to realize the heat dissipation operation of the stepping motor 2.
