The shell 3 is fixedly arranged on the upper portion of the base 1, an opening is formed in one side, close to the rotating disc 21, of the shell 3, and half of the rotating disc 21 penetrates through the opening to be located inside the shell 3. The first rotary driver 26 is preferably a servo motor, and when the device is used to remove burrs on the springs, the springs are firstly placed in the placing grooves 22 of the rotating disc 21, and it should be noted that since half of the rotating disc 21 is located in the housing 3, only half of the placing grooves 22 can be placed each time the springs are placed. When the springs are placed in the placing grooves 22, the clamping devices in the placing grooves 22 are in an open state, and due to the fact that the bearing plates 24 are arranged on the lower portion of the rotating disc 21, when the springs are placed in the placing grooves 22, the springs cannot fall off. Then the first rotary driver 26 is started, the first rotary driver 26 drives the rotary disc 21 arranged on the output end of the first rotary driver 26 to rotate, at this time, the rotary disc 21 drives the spring arranged in the placing groove 22 to rotate, after one side of the rotary disc 21 where the spring is placed is driven by the first rotary driver 26 to rotate into the housing 3, at this time, the positioning device 25 arranged on the rotary disc 21 can position the rotary disc 21, the positioning device 25 controls the first rotary driver 26 through a controller, when one side of the rotary disc 21 where the spring is not ground is completely rotated into the housing 3, the positioning device 25 can be activated, the positioning device 25 can control the first rotary driver 26 through the controller, so that the first rotary driver 26 stops running, then, the two lifting devices 27 arranged in the housing 3 can be started, the lifting devices 27 drive the grinding devices 28 arranged on the output end of the rotary disc 21 to approach to the rotary disc 21, and as both ends of the spring arranged on the rotary disc 21 are extended out of both side end faces of the rotary disc 21, the grinding devices 28 can grind the end faces of both ends of the spring at this time, and thus grinding of the end face of the spring is realized. Meanwhile, a new unpolished spring is placed in the placing groove 22 on the side, away from the shell 3, of the rotating disc 21, after the grinding device 28 finishes grinding the end face of the spring, the lifting device 27 drives the grinding device 28 to be away from the rotating disc 21, the ground spring is rotated out by the first rotary driver 26, and the unpolished spring enters the shell 3 again. Before the spring is polished by using the device, the standard value of the polished spring needs to be input by a control device, so that the lifting device 27 can drive the grinding device 28 to move through the value. The device can be used for loading and unloading the spring while grinding, the working efficiency is improved, and meanwhile, the standard numerical value of the spring is input, so that the error of the spring cannot be too large during grinding, and the machining precision of the spring is improved.

During spring loading, a signal transmitted by the signal transmitter 254 is received by the signal receiver 255 through the positioning hole 253. When the first rotary driver 26 drives the rotary disc 21 to rotate, the positioning plate 252 disposed on the rotary disc 21 blocks the signal emitter 254, at this time, the signal emitted by the signal emitter 254 cannot be received by the signal receiver 255, as the rotary disc 21 continues to rotate, the positioning hole 253 on the positioning plate 252 reaches the position below the signal emitter 254 again, at this time, the signal emitted by the signal emitter 254 passes through the positioning hole 253 and is received by the signal receiver 255, and the signal receiver 255 sends the signal to the controller, so that the controller controls the first rotary driver 26 to stop operating, thereby implementing the positioning function.
