[0007] A lifting mechanism is fixedly connected to the upper surface of the cover. The lifting mechanism includes a limiting frame and a connecting frame. The limiting frame is fixedly connected to the upper surface of the cover. An electric push rod is fixedly connected to the inner bottom surface of the limiting frame.

For large pins, they can be placed inside the fixed frame and the pin can be fixed by rotating the fastening bolt. At this time, the inner cylinder drives the abrasive to polish the pin, realizing the simultaneous polishing of multiple pins and improving the polishing efficiency of the device.

[0017] 2. Start the electric push rod. The electric push rod moves the mounting block, which causes the connecting frame to lift the polishing mechanism. This filters out some of the abrasive and prevents the outer and inner cylinders from obstructing the user's manual feeding, thus providing operating space for feeding. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 In this embodiment of the present invention, a high-precision pin polishing device includes a worktable 1, a rotary support 301 fixedly connected to the upper surface of the worktable 1, an outer cylinder 3 fixedly connected to the outer ring of the rotary support 301, the outer cylinder 3 being rotatably connected to the worktable 1 through the rotary support 301, and a cover 102 fixedly connected to the upper surface of the worktable 1.

[0025] A lifting mechanism 5 is fixedly connected to the upper surface of the cover 102. The lifting mechanism 5 includes a limiting frame 501 and a connecting frame 506. The limiting frame 501 is fixedly connected to the upper surface of the cover 102. An electric push rod 503 is fixedly connected to the inner bottom surface of the limiting frame 501. An installation block 504 is fixedly connected to the output end of the electric push rod 503. The connecting frame 506 is nested and connected to the outer surface of the installation block 504.

[0026] A polishing mechanism 6 is fixedly connected to the upper surface of the connecting frame 506. The polishing mechanism 6 includes a motor base 601, a fixing frame 602, and a rotating shaft 605. The motor base 601 is fixedly connected to the upper surface of the connecting frame 506, the fixing frame 602 is fixedly connected to the lower surface of the motor base 601, and the rotating shaft 605 is rotatably connected to the lower surface of the connecting frame 506. A hole frame 606 is fixedly connected to the outer surface of the rotating shaft 605.

[0027] Specifically, during use, abrasive is introduced into the inner cylinder 4, and then a high-precision pin is placed into the hole frame 606. The inner ring of the rotating support 301 is fixedly connected to the worktable 1. When the outer cylinder 3 rotates, it drives the inner cylinder 4 to rotate, causing the abrasive to rotate synchronously. At this time, the polishing mechanism 6 is activated, and the rotating shaft 605 drives the hole frame 606 to rotate, so that the abrasive and the pin in the hole frame 606 come into contact and polish the burrs on the pin surface. For larger pins, they can be placed inside the fixing bracket 602, and the pin can be fixed by rotating the fastening bolt 603. At this time, the inner cylinder 4 drives the abrasive to polish the pin. After the pin in the hole frame 606 is polished, the electric push rod 503 is activated. The electric push rod 503 drives the mounting block 504 to move, so that the connecting bracket 506 drives the polishing mechanism 6 to rise, which can filter out some of the abrasive and prevent the outer cylinder 3 and inner cylinder 4 from blocking the user from manually unloading the material, thus providing operating space for unloading. Example 1

[0028] like Figure 1-4 As shown, a support leg 101 is fixedly connected to the lower surface of the worktable 1, and a first stepper motor 2 is fixedly connected to the lower surface of the worktable 1. A gear 201 is fixedly connected to the output end of the first stepper motor 2, and the gear 201 is meshed with the outer ring of the rotary support 301.

[0029] In this embodiment, the first stepper motor 2 is started. The output end of the first stepper motor 2 drives the gear 201 to rotate. The gear 201, in conjunction with the outer ring of the rotary support 301, drives the outer cylinder 3 to rotate, which in turn drives the inner cylinder 4 to rotate.

[0030] like Figure 1-4 As shown, the lifting mechanism 5 also includes a controller 502 and a groove 505. The controller 502 is fixedly connected to the outer surface of the limit frame 501, and the groove 505 is opened on the outer surface of the mounting block 504. The connecting frame 506 matches the groove 505, and the outer surface of the connecting frame 506 is threaded with a bolt connection assembly 507.

[0031] In this embodiment, the controller 502 is used to control the electrical components. The connecting bracket 506 and the groove 505 are slidably connected. After tightening the bolt connecting component 507, the connecting bracket 506 can be fixed to the outer surface of the mounting block 504. After starting the electric push rod 503, the connecting bracket 506 can be driven to rise or fall, realizing the lifting and lowering of the hole frame 606, which facilitates the provision of operating space for the pin shaft to be unloaded later.

[0032] like Figure 1-4As shown, the polishing mechanism 6 also includes a fastening bolt 603 and a second stepper motor 604. The fastening bolt 603 is threadedly connected to the outer surface of the fixing frame 602. The second stepper motor 604 is fixedly connected to the upper surface of the motor base 601. The output end of the second stepper motor 604 is fixedly connected to the rotating shaft 605. A cover plate 607 is movably connected to the upper surface of the hole frame 606. A threaded sleeve 608 is movably connected to the upper surface of the cover plate 607. An inclined blade 7 is fixedly connected to the outer surface of the hole frame 606.

[0033] In this embodiment, the second stepper motor 604 is started, and the output end of the second stepper motor 604 drives the rotating shaft 605 to rotate, which in turn drives the hole frame 606 to rotate. The rotation direction of the hole frame 606 is opposite to that of the outer cylinder 3, which avoids a large amount of abrasive moving synchronously with the hole frame 606 and ensures the grinding and polishing effect that the device should have. The inner bottom of the hole frame 606 is fixedly connected with a stud, and the stud cooperates with the threaded sleeve 608 to fix the cover plate 607. The inclined blade 7 facilitates the diversion of abrasive. Example 2

[0034] Based on Example 1, in order to overcome the problem of inconvenience in removing the internal abrasive in Example 1.

[0035] like Figure 1-4 As shown, an inner cylinder 4 is slidably connected to the inner cylinder 3. A limiting groove 401 is formed on the outer surface of the inner cylinder 4, and a through hole 402 is formed on the inner surface of the inner cylinder 4 near the upper edge.

[0036] In this embodiment, a limiting strip is provided inside the outer cylinder 3. The limiting strip and the limiting groove 401 are slidably connected to provide auxiliary limiting for the inner cylinder 4. When the inner cylinder 4 is taken out, it can be manually lifted with the through hole 402 to facilitate the pouring out of the abrasive in the inner cylinder 4 later.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
