[0002] Existing polishing equipment is generally divided into two categories, one of which is to polish with a grinding wheel, and the other is to polish the workpiece with abrasives.

[0003] Among them, the polishing machine that uses abrasives to polish the workpiece needs to mix the abrasives in advance, and the abrasives are usually automatically loaded. An abrasive barrel is provided for storing the abrasives, and a stirring blade is usually installed in the abrasive barrel to stir the abrasives so that the abrasives will not settle. The abrasives in the abrasive barrel are stirred by the stirring blades. However, if the speed of the stirring blades is set faster, the abrasives will be consumed by the stirring blades, reducing the concentration of the abrasives. If the speed of the stirring blades is slow, the abrasives cannot be fully stirred so that the abrasives will not settle. Summary of the invention

[0004] In order to solve the problem that traditional polishing machines are prone to excessive stirring or insufficient stirring when stirring stored abrasives with stirring blades, the present application provides a polishing process based on ultrafine abrasives and equipment thereof.

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-2 This application is described in further detail.

[0021] In the first aspect, the present application embodiment discloses a polishing device based on ultrafine abrasive, referring to Figure 1 and Figure 2 , including a frame 1, an abrasive barrel 2 in the shape of a long cylindrical barrel and a polishing machine body, wherein the polishing machine body is fixedly mounted on the frame 1, the abrasive barrel 2 is rotatably mounted on the frame 1, and the rotation plane of the abrasive barrel 2 is vertical, the rotation axis of the abrasive barrel 2 passes through the center thereof, and the axis of the abrasive barrel 2 is parallel to its rotation plane.

[0022] Reference Figure 1 and Figure 2 A driving mechanism 3 is provided on the frame 1, and the driving mechanism 3 includes a driving motor 31 and a reducer 32 fixedly mounted on the frame 1. The driving motor 31 is transmission-connected to the reducer 32, and the output shaft of the reducer 32 is transmission-connected to the mounting shaft of the abrasive barrel 2. The abrasive barrel 2 is driven by the driving motor 31 to rotate slowly.

[0023] Reference Figure 1 and Figure 2 A discharge port 21 is provided through the middle of one end surface of the abrasive barrel 2. A sealing plate 22 is slidably installed on the same end surface of the abrasive barrel 2 and a stopper 24 is fixedly installed. An elastic member 23 is provided between the sealing plate 22 and the end surface of the abrasive barrel 2. The elastic member 23 is a spring. A protrusion is provided on the end surface of the abrasive barrel 2. The two ends of the spring are respectively connected to the protrusion on the end surface of the abrasive barrel 2 and one end surface of the sealing plate 22. The sealing plate 22 is pushed by the spring to fit tightly against the stopper 24, and at this time, the sealing plate 22 closes and covers the discharge port 21.

[0024] Reference Figure 1 and Figure 2 The frame 1 is provided with a timing mechanism 4, which includes a timing gear 41 coaxially axially sliding and radially fixedly mounted on the output shaft of the reducer 32, the timing gear 41 having only one gear tooth integrally arranged thereon, a driving gear 42 rotatably mounted on the frame 1, the driving gear 42 meshing with the timing gear 41. A driving wheel 43 is coaxially fixedly mounted on the driving gear 42, a lever 44 is fixedly mounted on the side wall of the driving wheel 43, a pressing switch 45 is fixedly mounted on the frame 1 directly below the driving wheel 43, and the lever 44 is used to press the pressing switch 45.

[0025] Reference Figure 1 and Figure 2 When the main shaft of the reducer 32 rotates one circle, the timing gear 41 drives the driving gear 42 and the driving wheel 43 to rotate one gear tooth.

[0026] Reference Figure 1 and Figure 2 A pushing member 5 is provided on the frame 1, and the pushing member 5 includes a first cylinder 52 fixedly mounted on the frame 1, and a push plate 51 is fixedly mounted on the piston rod of the first cylinder 52, the push plate 51 is arc-shaped, and the axis of the push plate 51 is coaxial with the rotation axis of the abrasive barrel 2, and the axis center of the piston rod of the first cylinder 52 is parallel to the arc axis of the push plate 51.

[0027] Reference Figure 1 and Figure 2 , the projection of the push plate 51 along the rotation axis direction of the abrasive barrel 2 is located on the rotation circle of the sealing plate 22. When the abrasive barrel 2 rotates to the point where the projection of the push plate 51 along the rotation axis direction of the abrasive barrel 2 is located on the side wall of the sealing plate 22, the driving wheel 43 just rotates to the lever 44 to press the push switch 45, and the first cylinder 52 is electrically connected to the push switch 45. When the push switch 45 is pressed, the first cylinder 52 starts to push the push plate 51 out. At this time, the push plate 51 pushes the sealing plate 22 away from the discharge port 21. A guide groove 511 with a triangular cross section is also provided on the top wall of the push plate 51. At this time, the vertical projection of the discharge port 21 is located in the guide groove 511.

[0028] Moreover, the two sides of the guide groove 511 in the length direction are flush with the two sides of the top wall of the push plate 51 in the length direction, so that after the push plate 51 pushes the sealing plate 22 open, when the abrasive flows onto the guide groove 511, it is not easy for the abrasive to flow between the contact side walls of the push plate 51 and the sealing plate 22, causing excessive wear of the contact side walls of the sealing plate 22 and the push plate 51.

[0029] Reference Figure 1 and Figure 2 The vertical projection of the lower end of the push plate 51 is located in the temporary storage groove 8. The abrasive output from the discharge port 21 will flow along the guide groove 511 to the temporary storage groove 8. The temporary storage groove 8 is connected to the feed end of the polishing machine body. The abrasive in the temporary storage groove 8 is used to supply the polishing machine body for polishing. Due to the short-term temporary storage, the particles in the abrasive will not precipitate, and the polishing effect is better.

[0030] Reference Figure 1 and Figure 2 A first limit cylinder 6 and a second limit cylinder 7 are also fixedly installed on the frame 1. A ball is rotatably installed on a section of the piston rod of the first limit cylinder 6 and the second limit cylinder 7. The two balls are respectively pressed against the end surface of the timing gear 41. When the piston rod of the first limit cylinder 6 extends and the piston rod of the second limit cylinder 7 contracts, the timing gear 41 is separated from the driving gear 42, otherwise the timing gear 41 is meshed with the driving gear 42.

[0031] Reference Figure 1 and Figure 2When the abrasive with adjusted ratio is poured into the abrasive barrel 2, the first limit cylinder 6 is started first, and the piston rod of the second limit cylinder 7 is retracted, so that the driving gear 42 and the counting gear are disengaged from each other. After the abrasive stirring is completed, the second limit cylinder 7 is started, and the piston rod of the first limit cylinder 6 is retracted, so that the driving gear 42 and the technical gear are engaged with each other, and the automatic feeding of the abrasive is started.

[0032] In a second aspect, the present application provides a polishing process based on ultrafine abrasives, comprising the following steps: S1, cleaning the workpiece after intermediate grinding; S2, pour the prepared abrasive into the abrasive barrel 2, then close the discharge port 21 through the sealing plate 22, then start the first limit cylinder 6, shrink the second limit cylinder 7, and start the drive motor 31 to drive the abrasive barrel 2 to rotate and stir the abrasive evenly; S3, after the abrasive is evenly stirred, the second limit cylinder 7 is started, the first limit cylinder 6 is retracted, and the abrasive barrel 2 normally supplies abrasive to the polishing machine body for polishing.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
