Description

Technical Field

[0001] This utility model belongs to the field of parts processing technology, and in particular relates to a polishing device for irregular parts. Background Technology

[0002] Polishing equipment for irregular parts is a specialized polishing device designed for parts with complex shapes, varied curved surfaces, or special structures (such as irregular curved parts, porous parts, gears, impellers, 3D printed parts, etc.). Its core objective is to solve the problem that traditional polishing methods (such as manual polishing and fixed fixture polishing) are difficult to uniformly process complex surfaces.

[0003] Existing polishing equipment for irregular parts typically involves placing the abrasive and the part together into a polishing cylinder, then rotating the cylinder to ensure full contact between the abrasive and the part, thus completing the polishing process. However, after prolonged polishing, debris generated from polishing the part mixes into the abrasive, requiring timely cleaning to prevent damage to the part's surface. Usually, cleaning requires workers to pour out the abrasive and debris together, which is time-consuming, labor-intensive, and leads to a reduction in overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a polishing device for irregular parts. By setting up a screening section, specifically by removing the connecting bolts between the polishing cylinder and the bottom cover, removing the bottom cover, loosening the bolts on both sides of the fixing ring one, moving it to the right to disengage it from gear two, and then re-fixing it to the right support platform. Similarly, the fixing ring two is operated, moved to the right, and fixed to the left support platform. At this time, the eccentric shaft is inserted into the annular groove of the swing block, and the motor two is started to drive the turntable and eccentric shaft to rotate clockwise, driving the polishing cylinder to swing clockwise around the rotating shaft. After the eccentric shaft reaches its limit position, the polishing cylinder swings counterclockwise, achieving reciprocating screening. The abrasive material, because its diameter is larger than the screen mesh, is retained, while the debris is separated through the screen mesh. This solves the problem of existing polishing devices requiring the abrasive and debris to be poured out together for screening before the abrasive is poured back into the polishing tank, which is inefficient and increases workload.

[0037] Please see Figures 1-6 As shown, this utility model is a polishing device for irregular parts, including a polishing cylinder 1, a top cover 11 installed on the top of the polishing cylinder 1, rotating shafts 14 fixedly connected to the left and right sides of the polishing cylinder 1, a support platform 12 rotatably connected to the polishing cylinder 1 via the two rotating shafts 14, a support leg 13 fixedly connected to the bottom of the support platform 12, and a bottom cover 15 installed at the bottom of the polishing cylinder 1 by bolts, and also includes:

[0038] Screening section 2, installed on the left side of polishing cylinder 1, is used to screen debris; and

[0039] Divider 3 is installed inside the polishing barrel 1 and is used to divide polishing areas of different sizes.

[0040] Among them, the support legs 13 at the bottom of the two support platforms 12 work together to support the polishing cylinder 1.

[0041] The screening unit 2 includes a power assembly 21, which is mounted on the top of the right support platform 12 and is used to rotate the polishing cylinder 1.

[0042] A swing assembly 22 is mounted on the top of the left support platform 12 and is used to swing the polishing cylinder 1.

[0043] The swing assembly 22 includes an eccentric shaft 223, and a swing block 224 is fixedly connected to the left side of the polishing cylinder 1. An annular groove is provided inside the swing block 224, and the eccentric shaft 223 and the annular groove inside the swing block 224 are in sliding limit cooperation.

[0044] The partition 3 includes a polishing tank 31, which is installed inside the polishing barrel 1 and is used to hold parts and abrasives.

[0045] The polishing cylinder 1 is equipped with a screen 34 at the bottom. The diameter of the screen holes inside the screen 34 is smaller than the diameter of the abrasive, and the diameter of the screen holes is larger than the diameter of the slag.

[0046] The power assembly 21 includes a motor 211, a retaining ring 212 fixedly connected to the outer surface of the motor 211, a gear 213 fixedly connected to the left output end of the motor 211 by bolts, and a gear 214 fixedly connected to the outer surface of the rotating shaft 14 located on the right side.

[0047] Among them, gear 1 213 and gear 2 214 are meshed and connected, and motor 1 211 causes polishing cylinder 1 to rotate through gear 1 213 and gear 2 214.

[0048] The support platform 12 located on the right side has two movable slots 215 inside, and the bottom of the fixing ring 212 slides and limits with the two movable slots 215 respectively.

[0049] Among them, the bottom of the fixing ring 212 has two screw holes on the front and back, and the two support platforms 12 have several screw holes inside.

[0050] The swing assembly 22 includes a second motor 221, with a second fixing ring 225 fixedly connected to the outer surface of the second motor 221. A turntable 222 is fixedly connected to the right output end of the second motor 221 by bolts. The right side of the turntable 222 is fixedly connected to the left side of the eccentric shaft 223. The bottom of the swing block 224 is fixedly connected to the outer surface of the rotating shaft 14 located on the left side. Remove the connecting bolts between the polishing cylinder 1 and the bottom cover 15, remove the bottom cover 15, loosen the bolts on both sides of the first fixing ring 212, and move it to the right to disengage it from the gear 214. Re-fix it to the right support platform 12, and similarly operate the fixing ring 225. After moving it to the right, fix it to the left support platform 12. At this time, the eccentric shaft 223 is inserted into the annular groove of the swing block 224. Start the motor 221 to drive the turntable 222 and the eccentric shaft 223 to rotate clockwise, driving the polishing cylinder 1 to swing clockwise around the rotating shaft 14. After the eccentric shaft 223 rotates to the limit position, the polishing cylinder 1 swings counterclockwise to achieve reciprocating screening. The abrasive is retained because its diameter is larger than the screen hole 34, while the debris is separated through the screen hole.

[0051] The support platform 12 on the left side has two movable slots 215 inside. The bottom of the fixing ring 225 is slidably limited to the two movable slots 215 respectively. The bottom of the fixing ring 225 has two screw holes on the front and back.

[0052] The polishing cylinder 1 has several slots 33 inside, and several partition plates 32 are inserted into the polishing tank 31. The front and back of the partition plates 32 are fixedly connected to the fixing rods 321. The slots 33 have circular grooves 331 inside, and the partition plates 32 are inserted into the two circular grooves 331 respectively through two fixing rods 321. The slots 33 have anti-blocking blocks 332 inside. The partition plates 32 are used to divide the space into small compartments of different sizes according to the size of the parts. The fixing rods 321 on both sides of the partition plates 32 are inserted into the circular grooves 331. The slots 33 that are not inserted into the partition plates 32 are blocked with anti-blocking blocks 332. The abrasive and the parts are poured into the polishing tank 31. The top cover 11 is closed and locked. The motor 1 211 is started and rotated clockwise. It drives the gear 2 214 on the outer surface of the right rotating shaft 14 to rotate counterclockwise through the gear 1 213. The rotating shaft 14 and the polishing cylinder 1 rotate accordingly, so that the abrasive in the polishing tank 31 and all parts of the parts can fully contact each other to complete the polishing.

[0053] Among them, the bottom of the anti-blocking block 332 is equipped with several rubber strips, which serve to prevent the anti-blocking block 332 from detaching from the polishing groove 31.

[0054] A specific application of this embodiment is as follows: When in use, open the top cover 11, and use the partition plate 32 to divide the space into small compartments of different sizes according to the size of the parts. Then, insert the fixing rods 321 on both sides of the partition plate 32 into the circular groove 331. At this time, the partition plate 32 is completely embedded in the slot 33. For the slots 33 where the partition plate 32 is not inserted, use the anti-blocking block 332 to insert into them. The bottom of the anti-blocking block 332 is fixed with several rubber strips, which can make the anti-blocking block 332 firmly inserted into the circular groove 331 to prevent the abrasive from entering the circular groove 331 and causing blockage during polishing. Then, pour the abrasive and the parts into the polishing tank 31, and then close and lock the top cover 11. Then, start the motor 211 to rotate clockwise. It drives the gear 214 on the outer surface of the right rotating shaft 14 to rotate counterclockwise through the gear 213. The rotating shaft 14 and the polishing cylinder 1 will rotate together. The abrasive in the polishing tank 31 will fully contact all parts of the parts to complete the polishing.

[0055] When it is necessary to clean the debris in the polishing tank 31, use a wrench to unscrew several bolts connecting the polishing cylinder 1 and the bottom cover 15, remove the bottom cover 15, and then use a wrench to unscrew the bolts on both sides of the fixing ring 1 212, moving the fixing ring 1 212 to the right. At this time, the gear 1 213 and the gear 2 214 are no longer meshed. Then, screw the bolts back into the screw holes inside the right support platform 12 to fix the fixing ring 1 212 to the right support platform 12. After that, use the same method to unscrew the bolts on both sides of the fixing ring 2 225, move the fixing ring 2 225 to the right, and retighten the bolts to fix the fixing ring 2 225 to the left support platform 12. At this time, the eccentric shaft on the right side of the turntable 222... 223 will be inserted into the annular groove inside the swing block 224, and then the motor 221 will be started to drive the turntable 222 and the eccentric shaft 223 to rotate clockwise. Since the swing block 224 is fixedly connected to the polishing cylinder 1, the polishing cylinder 1 will swing clockwise around the rotating shaft 14 located on the left. When the eccentric shaft 223 rotates to the front limit position and continues to rotate, the polishing cylinder 1 will swing counterclockwise around the rotating shaft 14. Through the continuous rotation of the motor 221, the polishing cylinder 1 will generate continuous swing, which will screen the abrasive in the polishing tank 31. Since the diameter of the abrasive is larger than the diameter of the screen hole on the screen 34, and the diameter of the debris is smaller than the diameter of the screen hole, the debris will be screened out.
