Further, guide pulley top and bottom are provided with a tensioning roller respectively, the tensioning hold-in range is walked around the tensioning roller in proper order, the tensioning roller forces the tensioning hold-in range to take over to the all side walls of guide pulley.
Furthermore, a hopper is arranged above the guide wheel, and a discharge hole for discharging the bar stock and butting with the guide wheel groove is formed in the bottom of the hopper.
Furthermore, a discharge chute is arranged below the guide wheel, and the inlet end of the discharge chute is positioned in the contact between the guide wheel and the bottom of the tensioning synchronous belt.
Furthermore, a shifting rod for shifting the bar material in the guide wheel groove out to fall into the discharge groove is fixed above the discharge groove.
Furthermore, the power mechanism comprises a servo motor and a power roller driven by the servo motor to rotate, and the power roller tightens and tensions the synchronous belt and drives the synchronous belt to rotate.
Compared with the prior art, the utility model discloses following beneficial effect has: this device is through installing a power unit additional on tensioning hold-in range for tensioning hold-in range can be along with guide pulley synchronous rotation, and under the cooperation of tensioning roller, has guaranteed that the bar has sufficient tensile force at the grinding in-process, and the bar can not the drunkenness, guarantees the grinding effect.
In order to make the aforementioned and other objects, features and advantages of the invention more comprehensible, preferred embodiments accompanied with figures are described in detail below.

Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description of the embodiments, structures, features and effects according to the present invention will be made with reference to the accompanying drawings and preferred embodiments.
As shown in fig. 1-3, a parallel surface grinding machine comprises a frame 1, wherein the frame 1 is rotatably connected with a guide wheel 2 through a first driving motor, and a plurality of guide wheel grooves 21 for placing bars are uniformly distributed on the circumferential side wall of the guide wheel 2; two sides of the guide wheel 2 are respectively provided with a grinding wheel 3, and the grinding wheels 3 are rotationally connected to the output ends of two second driving motors on the rack; the frame 1 is also fixedly provided with a servo motor 5 which is rotatably connected with a power roller 51, and the servo motor 5 drives the power roller 51 to rotate through belt transmission; the top and bottom of the guide wheel 2 are respectively rotatably connected with a tensioning roller 41. A tensioning synchronous belt 4 sequentially bypasses two tightening rollers 41 and a power roller 51, the power roller 51 drives the tensioning synchronous belt 4 to rotate, the two tightening rollers 41 force the tensioning synchronous belt 4 to press to a partial circumferential side wall of the guide wheel 2, and the power roller 51 enables the tensioning synchronous belt 4 to tension the guide wheel 2 without changing due to loosening or working of the synchronous belt, so that the tensioning force is uniform.
In this embodiment, the grinding wheel 3 grinds both ends of the bar stock pressed against the guide wheel 2 by the tension timing belt 4.
In this embodiment, a hopper 6 is disposed above the guide wheel 2, and a discharge port for discharging the bar material is disposed at the bottom of the hopper 6 and is abutted to the guide wheel groove 21, so that the bar material falling from the hopper is discharged through the discharge port into the guide wheel groove 21 and enters the area where the guide wheel contacts the tensioning synchronous belt along with the guide wheel 2. And is ground by the grinding wheel.
In this embodiment, the discharge gate is close to the lateral wall setting of guide pulley for each guide pulley groove can only take away a bar.
