Description

Technical Field

[0001] The utility model relates to the technical field of surface polishing of industrial products, in particular to an automatic polishing device. Background Art

[0002] Polishing refers to a processing method that uses machinery to reduce the surface roughness of industrial products to obtain a bright and smooth surface.

[0003] In the prior art, when a workpiece needs to be surface treated twice, two polishing discs corresponding to the number of surface treatments are generally used.

[0049] The following is a detailed explanation of the implementation of the present invention in conjunction with the accompanying drawings. The accompanying drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of the present invention.

[0050] See also Figure 1-Figure 3 In this embodiment, an automatic polishing device includes:

[0051] The rotating mechanism 1 is provided with at least two polishing discs 11;

[0052] A first drive 2, the output end of which is transmission-connected to the rotating mechanism 1 and capable of driving any of the polishing discs 11 to rotate to a polishing station;

[0053] The second drive 3 has an output end drivingly connected to the two polishing discs 11 and can drive the two polishing discs 11 to operate synchronously.

[0054] In this embodiment, the rotating mechanism 1 is an equilateral triangle block structure, and there are three polishing discs 11. The synchronous rotation is achieved through a single set of programs in the second drive 3. The granularity of the three polishing discs 11 is different. When the three polishing discs 11 are rotated until the surface treatment of the blank is completed, the three polishing discs 11 are controlled by the first drive 2 to be located in the polishing station in succession. During operation, a robot is required to fix the blank on the aforementioned polishing station; the processes performed in succession can be but are not limited to: rough processing, rough processing, and fine processing.

[0055] Preferably, it also includes:

[0056] The fixed frame 4 is provided with a rotatable first rotating shaft 41, one end of the first rotating shaft 41 is transmission-connected to the first driving 2, and the other end is connected to the rotating mechanism 1;

[0057] The positioning mechanism 42 is disposed on the fixing frame 4 and acts on the rotating mechanism 1 . When the polishing disc 11 rotates to the polishing position, the first driving mechanism 2 can stop working.

[0058] In this embodiment, a bottom plate is also included, and the legs of the fixing frame 4 are fixed on the bottom plate. The positioning mechanism 42 is used to control the rotation angle of the rotating mechanism 1 to ensure that the polishing disc 11 corresponding to the subsequent process can be rotated to the polishing station. Specifically, taking three polishing discs 11 as an example, when switching processes, the angle of rotation of the rotating mechanism 1 around the axis of the first rotating shaft 41 is 120°, and the expansion of the station is achieved through turnover. For example, in the prior art, the space occupied by two polishing discs 11 can only be used for the workpiece to achieve two processes. In this embodiment, under the condition of almost the same or no additional increase in layout space, the expansion of three processes, i.e., three stations, is achieved, which can adapt to the processing technology of more and more complex products.

[0059] Preferably, the positioning mechanism 42 includes:

[0060] A proximity switch 421 is provided on the fixing frame 4;

There are 3 sensing sheets in total, which are fixed on the three corners of the rotating mechanism 1 accordingly. The sensing sheet 422 includes a connected fixing sheet and a protruding sheet. The fixing sheet is fixedly connected to the rotating mechanism 1 by screws. When the proximity switch 421 detects the protruding sheet, it transmits an electrical signal to the information processing component, and the information processing component transmits a stop signal to the first drive 2, so that the polishing disc 11 corresponding to the sensing sheet 422 is moved to the polishing station, so that the polishing disc 11 with different particle sizes can be replaced at the same polishing station.

[0064] Preferably, it also includes:

[0065] The locking mechanism 43 is disposed on the fixing frame 4 and acts on the rotating mechanism 1 . When the polishing disc 11 rotates to the polishing station, the locking mechanism 43 can continuously provide a locking force for stopping the rotating mechanism 1 .

[0066] In this embodiment, when the polishing disc 11 of the corresponding process rotates to the polishing station, the locking mechanism 43 is used to act on the rotating mechanism 1 to provide it with a locking support force to fix it in the current position, thereby preventing the polishing disc 11 performing the current process from shifting relative to the polishing station during the processing, which is beneficial to improving the processing accuracy and reducing safety hazards.

[0071] In this embodiment, when the polishing disc 11 of the corresponding process rotates to the polishing station, the locking rod 431 is slid close to the side of the rotating mechanism 1 and inserted into the socket 432 to achieve the purpose of locking; specifically, the third drive 433 is a cylinder, and a cylinder seat for mounting the cylinder is on the fixed frame 4, and the piston rod of the cylinder is transmission-connected to the end of the locking rod 431 away from the rotating mechanism 1, and the solenoid valve of the third drive 433 is connected to the external air source through the information processing component, and further includes a wear-resistant sleeve, which is coaxially penetrated in the socket 432, thereby buffering the thrust of the cylinder pushing the locking rod 431, and through the indirect contact between the locking rod 431 and the socket 432, the wear on the socket 432 and the locking rod 431 is reduced, which is beneficial to improving the service life.
