Abstract
Description
Technical Field
[0001] This utility model belongs to the field of polishing equipment technology, and in particular relates to a multi-face synchronous automatic polishing mechanism for workpieces. Background Technology
[0002] A polishing machine is a device that uses a high-speed rotating grinding head or polishing disc, along with abrasives or polishing wax, to grind and polish the surface of an object. It is widely used in the processing of various materials such as metal, wood, stone, and plastic, whether it is for repairing paint on car bodies, smoothing furniture surfaces, or mirror polishing of metal parts.
[0003] During the polishing process, not only is the workpiece ground by the abrasive, but its inner liner is also worn down by the abrasive. Therefore, the inner liner needs to be replaced frequently. Conventional polishing equipment requires disassembling and reassembling multiple screws to replace it, which makes the replacement of the inner liner of conventional polishing machines quite troublesome.
[0004] Therefore, we propose a multi-face synchronous automatic grinding mechanism for workpieces to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to solve the problem of the cumbersome replacement of the inner liner of conventional polishing machines, and to propose a multi-face synchronous automatic polishing mechanism for workpieces.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A multi-faceted synchronous automatic grinding mechanism for workpieces includes a geared motor, an externally mounted frame, and a rotating drum fixedly connected to the output shaft of the geared motor. An inner liner is held inside the rotating drum, and a threaded bracket is fixedly connected inside the rotating drum. A first threaded ring is installed on the external thread of the threaded bracket. When the inner liner becomes excessively worn, the first threaded ring is unscrewed, the inner liner is pulled out, a new inner liner is placed back in, and the first threaded ring is tightened again. The first threaded ring presses against the outside of the inner liner, keeping it inside the rotating drum for easy replacement of the inner liner.
[0008] Preferably, the outer surface of the first threaded ring is provided with anti-slip texture. The anti-slip texture facilitates the increase of friction between the hand and the first threaded ring.
[0009] Preferably, guide wheels are rotatably mounted on the lower part of the frame, and the rotating drum is mounted on the guide wheels. The rotating drum is supported by the rolling of the guide wheels, which reduces the load on the output shaft of the geared motor.
[0010] Preferably, the rotating drum includes a cylindrical body, the rear of which is hollowed out and has an insertion port, and a limiting block is fixedly connected to the middle of the cylindrical body. The limiting block, positioned inside the inner liner, increases the stability of the inner liner's position.
[0011] Preferably, the threaded bracket includes a connecting rod, one end of which is fixedly connected to the cylinder body, and the other end of which is fixedly connected to a second threaded ring. A first threaded ring is threaded onto the outside of the second threaded ring. By unscrewing the first threaded ring from the second threaded ring, the outer side of the inner liner is no longer obstructed. By screwing the first threaded ring onto the outside of the second ring, the first threaded ring presses against the inner liner, making it easy to open or lock the inner liner.
[0012] Preferably, the inner liner includes a shell, and a baffle is fixedly connected inside the shell. When the inner liner rotates, the baffle acts on the sand and workpiece inside, increasing the fluidity between the sand and the workpiece.
[0013] In summary, the technical effects and advantages of this utility model are as follows:
[0014] 1. When the inner liner is excessively worn, unscrew the first threaded ring, pull out the inner liner, put the new inner liner back in, and then tighten the first threaded ring. Use the first threaded ring to press the inner liner outside, keeping the inner liner inside the rotating drum, which makes it easy to replace the inner liner.
[0015] 2. Unscrew the first threaded ring off the second threaded ring to remove the obstruction to the outside of the inner liner. Screw the first threaded ring off the second threaded ring and use the first threaded ring to press down on the inner liner, making it easy to open or lock the inner liner.

[0021] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.
[0022] like Figure 1As shown, the multi-face synchronous automatic polishing mechanism for workpieces includes a geared motor 1, an externally fixed frame 7, a rotating drum 2 fixedly connected to the output shaft of the geared motor 1, an inner liner 4 snapped into the inside of the rotating drum 2, a threaded bracket 3 fixedly connected inside the rotating drum 2, and a first threaded ring 6 installed on the external thread of the threaded bracket 3. Sand is poured into the inner liner 4, and the workpiece is placed inside the inner liner 4. The geared motor 1 drives the rotating drum 2 to rotate, which in turn drives the inner liner 4 to rotate, causing the sand inside the inner liner 4 to roll and polish the workpiece.
[0023] like Figure 1 As shown, the outer surface of the first threaded ring 6 is provided with anti-slip texture. The anti-slip texture increases the friction between the hand and the first threaded ring 6.
[0024] like Figure 1 As shown, a guide wheel 5 is rotatably mounted on the lower part of the frame 7, and the rotating drum 2 rolls on the guide wheel 5. The guide wheel 5 rolls to support the rotating drum 2, reducing the load on the output shaft of the geared motor 1.
[0025] like Figure 1 and 2 As shown, the rotating cylinder 2 includes a cylinder body 21, with an insertion port 22 hollowed out at the rear of the cylinder body 21, and a limiting block 23 fixedly connected to the middle of the cylinder body 21. The limiting block 23 is used to block the inner liner 4 from the inside, increasing the positional stability of the inner liner 4.
[0026] like Figure 1 and 3 As shown, the threaded bracket 3 includes a connecting rod 31. One end of the connecting rod 31 is fixedly connected to the cylinder 21, and the other end of the connecting rod 31 is fixedly connected to a second threaded ring 32. A first threaded ring 6 is threaded onto the outside of the second threaded ring 32. The first threaded ring 6 is unscrewed from the second threaded ring 32, so that the outside of the inner liner 4 is no longer obstructed. The first threaded ring 6 is then screwed onto the outside of the second threaded ring 32, using the first threaded ring 6 to press down on the inner liner 4.
[0027] like Figure 1 and 4 As shown, the inner liner 4 includes a shell 41, and a baffle 42 is fixedly connected inside the shell 41. When the inner liner 4 rotates, the baffle 42 acts on the sand and workpiece inside, increasing the fluidity between the sand and the workpiece.
[0028] Working principle: Sand is poured into the inner liner 4, and the workpiece is placed inside the inner liner 4. The geared motor 1 drives the rotating drum 2 to rotate, which in turn drives the inner liner 4 to rotate, causing the sand inside the inner liner 4 to roll and grind the workpiece. When the inner liner 4 is excessively worn, the first threaded ring 6 is unscrewed, the inner liner 4 is pulled out, a new inner liner 4 is placed back, and the first threaded ring 6 is tightened. The first threaded ring 6 is used to press the inner liner 4 outside, keeping the inner liner 4 inside the rotating drum 2, thus realizing the replacement of the inner liner 4.
[0029] The above description is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the utility model, based on the technical solution and the inventive concept of the utility model, should be included within the scope of protection of the utility model.
[0030] The description briefly mentions the application direction of the utility model in relation to existing technologies known to those skilled in the art without modification, and combines them with the utility model to form a complete technology; it avoids excessive popularization of technologies known to those skilled in the art, in order to help those skilled in the art quickly understand the main content of the utility model.
