Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, in particular to a multi-station polishing machine. Background Art

[0002] Polishing machines are mechanical devices used to polish or buff surfaces. They are commonly used for surface treatment of materials such as metal, plastic, stone, wood, etc. The working principle of a polishing machine is to apply force to the surface of the workpiece through a rotating abrasive or polishing cloth, thereby achieving a smooth and shiny surface.

[0003] The current polishing machine can only polish one workpiece at a time, and after polishing, the equipment needs to be stopped to remove the polished workpiece. Since only one workpiece can be processed at a time, it means that a lot of manual operation and downtime are required to replace the workpiece. This will lead to stagnation of the production line and reduced production efficiency. In addition, downtime and workpiece replacement time will increase the time consumption of the entire production cycle. Workers must wait for the equipment to stop and safely remove the workpiece, and then restart the equipment to process the next workpiece. These steps take time. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a multi-station polishing machine, which solves the problem that only one workpiece can be polished in a single processing and the equipment needs to be stopped to remove the polished workpiece after polishing.

[0011] The polishing assembly is arranged on the movable plate, so that the movable plate drives the polishing assembly to move up and down when moving up and down, and polishes the workpiece on the electromagnetic chuck at the same time.

[0012] Furthermore, one end of the screw rod away from the driving motor is connected to the column through a bearing seat.

[0013] Furthermore, a slope is provided on both the front and rear sides of the column, and the two polishing mechanisms are respectively arranged on the two slopes.

[0014] Further, the polishing assembly includes a rotating motor, a synchronous pulley structure, a planetary grinding head and at least three grinding wheels;

At the same time, the CNC turntable rotates appropriately, and the abrasive wire on the grinding wheel performs universal high-speed blunt angle polishing on the hole, notch, and edge of the workpiece, so as to quickly remove the sharp corners of the workpiece and improve the roughness.

[0020] 2. In the multi-station polishing machine, each rotation of the CNC turntable to one station is a beat. In this embodiment, seven electromagnetic chucks are preferably used, and the electromagnetic chuck on the far right opposite to the column is the loading and unloading station.

[0027] In actual use, multiple workpieces are placed on the electromagnetic chuck 3 on the CNC turntable 2, and the workpieces are fixed by the electromagnetic chuck 3. Only one workpiece can be placed on each electromagnetic chuck 3, and the workpieces below can be polished through the cooperation between the internal components of the two polishing mechanisms 5.

[0028] It should be noted that each rotation of the CNC turntable 2 at one workstation is a beat, and in this embodiment, seven electromagnetic suction cups 3 are preferably used, and the electromagnetic suction cup 3 on the far right opposite to the column 4 is a loading and unloading workstation. When the polished workpiece rotates to the rightmost workstation, the workpiece on the rightmost workstation can be removed from the electromagnetic suction cup 3 and replaced with a new workpiece.

After multiple beats of the CNC turntable 2, the new workpiece can be moved to the bottom of the polishing mechanism 5. In this way, a completed workpiece can be removed and replaced with a new one in each continuous beat.

[0030] In actual use, the output end of the driving motor 504 is rotated to drive the screw 503 connected thereto to rotate, and the height of the movable plate 502 can be adjusted at this time, and the height of the polishing assembly can be adjusted at the same time to ensure that appropriate pressure is maintained between the polishing assembly and the workpiece, and to ensure that the polishing assembly can effectively contact the outer surface of the workpiece during operation.

[0031] In addition, one end of the screw rod 503 away from the driving motor 504 is connected to the column 4 through a bearing seat. The front and rear sides of the column 4 are each provided with an inclined surface, and the two polishing mechanisms 5 are respectively arranged on the two inclined surfaces.

[0034] In actual use, the distance between the grinding wheel 508 and the workpiece is adjusted by the lifting assembly, so that the three grinding wheels 508 are all in contact with the workpiece, and the output end of the rotating motor 505 is rotated to drive the synchronous pulley structure 506 to rotate, thereby driving the three grinding wheels 508 to rotate around the central axis of the grinding head. At the same time, through the transmission with the planetary grinding head 507, the grinding wheel 508 itself is in a high-speed rotation state, so that the workpiece is effectively polished. At the same time, the CNC turntable 2 rotates appropriately, and the abrasive wire on the grinding wheel 508 performs universal high-speed blunting and polishing on the hole openings, slots, and corners on the workpiece, so as to quickly remove the sharp corners of the workpiece and improve the roughness.

[0035] It should be noted that in order to ensure that the grinding wheel 508 can effectively polish the workpiece during the rotation process, the center point of the planetary grinding head 507 in this embodiment is located on the motion trajectory of the electromagnetic suction cup 3, and at least three grinding wheels 508 are distributed in a circular array inside the planetary grinding head 507.
