The second drive motor 15 is arranged on the mounting table 11. The second drive motor 15 and the first drive motor 12 are symmetrically arranged. The second drive motor 15 is connected to the electric chuck 13. The electric chuck 13 belongs to the existing technology and no improvement is made. The clamping and rotating assembly is cooperated with the second servo motor 23 and the moving assembly to realize effective clamping of the steel rod 4 and realize uniform rotation to complete the subsequent surface grinding process.

[0029] Further optimization of the embodiment of the utility model is as follows: Figure 1 and Figure 2 As shown, the driving assembly includes a screw assembly 31 and an electric push rod 32. The mounting plate 3 is provided with the screw assembly 31, which belongs to the prior art and does not require any improvement. The screw assembly 31 is composed of a power motor, a screw, a guide rod and a moving block, etc. These structures are shown in the figure without being numbered. The screw assembly 31 is provided with an electric push rod 32. Specifically, the moving block is provided with an electric push rod 32, and the electric push rod 32 is connected to a grinding block 33; the driving assembly is used to successively realize the horizontal positioning and vertical lifting of the grinding block 33 and then contact one end of the steel rod 4, and finally the grinding block 33 reciprocates in the horizontal direction to complete the surface grinding process of the steel rod 4; it is further explained that the mounting hole 25, the grinding wheel 14 and the electric chuck 13 are concentric to ensure the processing quality of the steel rod.

[0030] It should be noted that the first servo motor 1, the second servo motor 23, the electromagnetic ring 26, the electric cylinder 2, the first drive motor 12, the second drive motor 15, the electric chuck 13, the screw assembly 31 and the electric push rod 32 are all electrically connected to the controller. The controller is not shown in the figure, and the control principle of the controller belongs to the prior art and is not described.

[0031] The workflow of this utility model:

[0032] First, manually insert the steel rod 4 from one end of the mounting hole 25 into the fixing platform 24 so that the lengths extending from both sides are roughly equal. At this time, the surface of the steel rod 4 fits with the electromagnetic ring 26, and then the controller controls the electromagnetic ring 26 to energize to achieve the adsorption and fixation of the steel rod 4 inside the fixing platform;

[0033] After the position of the steel rod 4 is limited, the controller immediately controls the electric cylinder 2 and the first drive motor 12 to work. After the electric cylinder 2 works, it can drive the slider 22 to move along the slide rail 21 so that one end side of the steel rod 4 is close to the grinding wheel 14. The first drive motor 12 works to drive the grinding wheel 14 to rotate at a high speed. When the side surface of one end of the steel rod 4 contacts the grinding wheel 14, the controller immediately controls the electric cylinder 2 to stop. At this time, one end surface of the steel rod 4 begins to be polished. After the grinding is completed, the controller controls the electric cylinder 2 to retract. At this time, the steel rod 4 is away from the grinding wheel 14 for a distance. Then the controller controls the second servo motor 23 to work and drive the fixed table 24 to rotate 180 degrees. At this time, the other end side of the steel rod 4 is facing the grinding wheel 14 and the grinding wheel 14 is still in a high-speed rotation state. Then the controller controls the electric cylinder 2 to work and extend again so that the other side surface of the steel rod 4 is also in contact with the grinding wheel 14 for grinding. Thus, both sides of the steel rod 4 are polished.

[0034] After the side grinding is completed, the steel rod 4 is again away from the grinding wheel 14 under the action of the electric cylinder. After it is away from the grinding wheel 14, the controller controls the first drive motor 12 to stop working. At the same time, the controller controls the first servo motor 1 to work. The operation of the first servo motor 1 can drive the mounting table 11 to rotate 180 degrees so that the electric chuck 13 is facing the side of one end of the steel rod 4. Then the controller controls the electric cylinder 2 to extend again to drive one end of the steel rod 4 to enter the electric chuck 13. When the steel rod 4 enters the electric chuck 13, the controller immediately controls the electric chuck 13 to work to complete the clamping and fixing of one end of the steel rod 4. After the fixation is completed, the controller controls the electromagnetic ring 26 to cut off the power, and then controls the electric cylinder 2 to retract so that the steel rod 4 is completely separated from the fixing table 24. After the steel rod 4 is separated from the fixing table 24, the controller controls the second drive motor 15 to work so that the steel rod 4 rotates at a uniform speed. After the steel rod 4 rotates, the controller controls the screw assembly 31 to move for positioning. When the grinding block 33 moves to above one end of the steel rod 4, the controller immediately controls the screw assembly 31 to move. The rod assembly 31 stops moving. After the screw assembly 31 stops moving, the controller controls the electric push rod 32 to extend so that the grinding block 33 approaches and contacts the surface of the steel rod 4 for grinding. As the grinding progresses, the controller controls the screw assembly 31 to make a uniform reciprocating motion to realize the grinding process of the surface of the steel rod 4. It should be noted that the automatic positioning of the screw assembly 31 is controlled by the controller program and scanned in conjunction with the laser sensor. The laser sensor is not shown in the figure and belongs to the principle of the prior art and will not be described. The screw assembly 31 can move as far as the electric chuck 13; when the grinding of a steel rod 4 is completed, the controller immediately controls the electric cylinder 2 to retract back to the initial state, and then the electric chuck 13 is released from the fixation. After it is manually removed, the controller controls the two servo motors to return to the initial state, that is, to rotate 180 degrees in the opposite direction. At the same time, the grinding block 33 is also controlled by the controller to move away from the steel rod 4 so as not to affect the placement of the next steel rod 4. Then a new steel rod 4 can be installed and the above process can be repeated for grinding;

[0035] Compared with the prior art, the device can automatically and effectively grind both sides and the surface of the steel rod 4, and the grinding block 33 does not need manual adjustment, and the degree of automation is significantly improved. At the beginning, it is only necessary to insert the steel rod 4 into the fixed table 24, and take it out from the electric chuck 13 after grinding. The operation is simple and time-saving.

[0036] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions in the specification are only to illustrate the principles of the utility model.
