[0085] The rotating disk 2 is rotatably mounted inside the first rotating frame 101 and is driven to rotate by a rotating driving assembly;

[0086] The clamping assembly is installed in a linear array inside the rotating disk 2, and is used to clamp the workpiece, and drive the workpiece to rotate at high speed after driving the workpiece to move to the top;

[0087] A loading assembly is installed on the top of the base 1 and is used to load the workpiece to the clamping assembly moved to the bottom;

[0088] A chamfering assembly is installed on the top of the base 1, and is used to perform chamfering processing on the workpiece clamped by the clamping assembly, and to perform negative pressure recovery on the debris generated by the chamfering during the processing;

[0089] Some chamfering machines will generate a lot of iron chips during the processing, and lack effective protection measures, which can easily cause iron chips to splash and pose a safety hazard. Therefore, it is necessary to set a dust box or iron chip collection device inside the chamfering machine to centrally collect the iron chips generated during the processing;

[0090] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the loading component transports the workpiece to be processed in the direction of the rotating disk 2. When the workpiece is transported to the bottom position aligned with the clamping component, the workpiece is pushed toward the clamping component so that the workpiece is clamped by the clamping component.

At the same time, when the clamping component moves the workpiece to the top, it drives the workpiece to rotate rapidly, so that the workpiece moved to the top is aligned with the chamfering component while rotating rapidly, thereby realizing chamfering processing of the workpiece. While the chamfering component is chamfering the workpiece, the chamfering position is relatively sealed, and at the same time, the debris generated by the chamfering processing is negatively pressured in the relatively sealed space, so that the debris generated by the processing is recovered in the relatively sealed space when it is generated, so that the debris will not splash outward, which is conducive to avoiding the splashing of large debris generated during the processing and causing safety hazards.

The pushing plate 801 pushes the workpiece blocked by the arc plate 802 to move toward the second rotating frame 3, thereby realizing the loading of the workpiece.

[0144] As an optional embodiment, the rotation drive assembly includes:

[0145] The first motor 201 is fixed on the first rotating frame 101;

[0146] The first gear 202 is fixed to the end of the output shaft of the first motor 201;

[0147] The second gear 203 is fixed on the outer wall of the rotating disk 2, and the second gear 203 is meshed with the first gear 202;

[0148] After the first motor 201 is started, the output shaft drives the first gear 202 connected thereto to rotate. The first gear 202 rotates and drives the second gear 203 meshing therewith to rotate. The second gear 203 rotates and drives the rotating disk 2 fixed thereto to rotate, thereby realizing the rotation drive of the rotating disk 2.

[0149] The working principle of the present invention is as follows: the loading component transports the workpiece to be processed toward the rotating disk 2, and when the workpiece is transported to the bottom position aligned with the clamping component, the workpiece is pushed toward the clamping component so that the workpiece is clamped by the clamping component, and the rotating driving component drives the rotating disk 2 to rotate, so that the rotating disk 2 drives the clamping component to rotate, so that the clamping component rotates the workpiece clamped at the bottom position and transports it to the top, so that the workpiece moves to the top and is aligned with the chamfering component at the top. At the same time, when the clamping component moves the workpiece to the top, it drives the workpiece to rotate rapidly, so that the workpiece moved to the top is aligned with the chamfering component while rotating rapidly, thereby realizing the chamfering of the workpiece. While the chamfering component is chamfering the workpiece, the chamfering position is relatively sealed, and at the same time, the debris generated by the chamfering is recovered under negative pressure in the relatively sealed space, so that the debris generated by the processing is recovered in the relatively sealed space when it is generated, so that the debris will not splash outward, which is conducive to avoiding the splashing of large debris generated during the processing to cause safety hazards.

[0150] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
