Description

Technical Field

[0001] This utility model relates to the field of dust cover processing technology, specifically a deburring device for dust cover production. Background Technology

[0002] Dust covers are a very important industrial component. They are made by stamping thin metal sheets. During the stamping process, pressure is applied to the metal sheet through a die, causing it to undergo plastic deformation to obtain the desired shape. During stamping, the cutting edge of the die interacts with the metal sheet. Due to factors such as the plastic flow of the sheet and the wear of the die cutting edge, burrs will inevitably be generated on the edge of the dust cover. When the blanking force is large and the die cutting edge is not sharp enough, the fibrous structure of the material will be torn instead of being cut cleanly at the moment the metal sheet is cut, thus forming burrs.

[0003] Traditional manual deburring methods have certain shortcomings in dust cover production. Manual operation mainly relies on workers to use tools such as sandpaper and files to grind and remove burrs from dust covers. This method is inefficient, especially in large-scale production, and cannot meet production needs. Moreover, the quality of manual deburring is unstable, depending on the worker's skill level and working condition, resulting in inconsistent product quality. To address these issues, a deburring device for dust cover production is proposed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] like Figure 1-5As shown, this utility model provides a technical solution: a deburring device for producing dust covers, including a base 1, a processing table 101 fixedly connected to the top outer surface of the base 1, a processing groove 102 formed at the center of the processing table 101, support frames 2 fixedly connected to the top of both sides of the processing table 101, a placement tube 201 fixedly connected to the center of the support frame 2, the placement tube 201 being positioned directly above the processing groove 102, a sliding groove 202 formed on the inner surface of the placement tube 201, a hollow ring 203 movably connected to the inner wall of the sliding groove 202, a return spring 204 fixedly connected to the bottom outer end of the hollow ring 203, a locking frame 205 fixedly connected to the bottom of the hollow ring 203, and a top outer side of the locking frame 205 fixedly connected to... A force-bearing block 206 is attached, and a cam 207 is provided on the top of the force-bearing block 206. A connecting rod 208 is fixedly connected to the inner wall of the cam 207. A drive motor 209 is movably connected to the outer side of the connecting rod 208. A grinding ring 210 is fixedly connected to the bottom outer side of the clamping bracket 205. A dust cover body 211 is movably connected to the bottom of the grinding ring 210. A suction cup 3 is movably connected to the bottom outer surface of the dust cover body 211. A connecting pipe 301 is fixedly connected to the bottom center of the suction cup 3. A slot 302 is provided on one side of the outer wall of the connecting pipe 301. A small vacuum pump 303 is fixedly connected to the bottom outer wall of the connecting pipe 301. A placement seat 304 is provided on the outside of the small vacuum pump 303. A leakage hole 305 is provided on the outside of the placement seat 304.

[0024] According to the overall structure of the device, the operator places the dust cover body 211 on the top outer side of the suction cup 3, and then starts the small vacuum pump 303. The vacuum pump draws air from the suction cup 3 through the connecting pipe 301, creating a negative pressure environment inside the suction cup 3, so that the dust cover body 211 is tightly adsorbed onto the suction cup 3, completing the fixation of the workpiece. At this time, the dust cover body 211 is located directly below the grinding ring 210. The grinding ring 210 is located at a higher position inside the placement tube 201 and is not in contact with the dust cover body 211. The return spring 204 is in a naturally extended state. Then, the drive motor 209 is started. The drive motor 209 drives the connecting rod 208 to rotate inside the placement tube 201. The connecting rod 208 drives the externally fixed cam 207 to rotate. When the protruding part of the cam 207 contacts the force block 206, the force block 206 is subjected to downward pressure. The force causes the hollow ring 203 to slide downwards along the groove 202 on the inner wall of the placement tube 201, while simultaneously compressing the return spring 204. At the same time, the grinding ring 210 at the bottom of the clamping bracket 205 covers the outer surface of the dust cover body 211 as the hollow ring 203 descends. During the fit, the outer edge of the dust cover body 211 is ground to remove burrs. As the drive motor 209 continues to rotate, it drives the cam 207 to rotate continuously, causing the force block 206 to be subjected to pressure and release pressure periodically. This causes the grinding ring 210 to move up and down in the groove 202, fully grinding and removing burrs from the outer edge of the dust cover body 211. The debris generated during the grinding process enters the device through the bottom hole 305 for collection and is uniformly processed by the staff to prevent waste from accumulating in the processing area and affecting the processing effect and normal operation of the equipment.

[0025] like Figure 1-5 As shown, the force-bearing block 206 is fixed to the center of the hollow ring 203 by the clamping bracket 205. The outer wall of the protruding side of the cam 207 is in contact with the outer top of the force-bearing block 206. One side of the connecting rod 208 passes through the outside of the placement tube 201 and is rotatably connected to the drive motor 209. The other side of the connecting rod 208 is rotatably connected to the inner wall of the support frame 2. The cam 207 forms a rotating structure with the force-bearing block 206 through the cooperation of the connecting rod 208 and the drive motor 209. The placement tube 201 is set directly above the dust cover body 211 by the support frame 2. The grinding ring 210 is set at the center of the interior of the placement tube 201. The inner wall of the placement tube 201 is annularly opened. The outer wall of the hollow ring 203 is fixed with a protrusion that fits against the inner wall of the slide groove 202. The hollow ring 203 is slidably connected to the inner wall of the slide groove 202. The return spring 204 is fixed to the inner wall of the bottom end of the slide groove 202. The grinding ring 210 is fixed at the bottom center of the clamping bracket 205. The grinding ring 210 is hollow and annularly arranged. The inner wall surface of the grinding ring 210 is tightly fitted with the outer wall surface of the dust cover body 211. The grinding ring 210 forms a lifting structure with the dust cover body 211 through the cooperation between the force block 206, the cam 207 and the drive motor 209.

[0026] The drive motor 209 drives the connecting rod 208 to rotate inside the placement tube 201. The connecting rod 208 drives the externally fixed cam 207 to rotate. When the protruding part of the cam 207 contacts the force block 206, the force block 206 is subjected to downward pressure, causing the hollow ring 203 to slide down along the slide groove 202 on the inner wall of the placement tube 201. At the same time, the return spring 204 is compressed. Meanwhile, the grinding ring 210 at the bottom of the locking bracket 205 covers the outer wall surface of the dust cover body 211 as the hollow ring 203 descends. When it is in contact, the outer edge of the dust cover body 211 is ground to remove burrs. As the drive motor 209 continues to rotate, it drives the cam 207 to rotate continuously, causing the force block 206 to be subjected to pressure and release pressure periodically. This causes the grinding ring 210 to move up and down in the slide groove 202, which fully grinds and removes burrs from the outer edge of the dust cover body 211.

[0027] like Figure 1-5 As shown, the suction cup 3 is made of rubber. The dust cover body 211 is attached to the top outer side of the suction cup 3. The outer diameter of the dust cover body 211 is larger than the outer diameter of the suction cup 3. The connecting tube 301 is fixed through and fixed at the bottom center of the suction cup 3. The slot 302 is opened at the top center of the placement seat 304. The inner surface of the slot 302 is tightly fitted with the outer surface of the connecting tube 301. The placement seat 304 is fixed at the inner center of the processing groove 102. The dust cover body 211 is set at the top center of the suction cup 3. The drain hole 305 is opened at the bottom of the processing groove 102. The drain hole 305 is circumferentially opened about the outside of the placement seat 304.

[0028] By starting the small vacuum pump 303, the vacuum pump draws air from the suction cup 3 through the connecting pipe 301, creating a negative pressure environment inside the suction cup 3, so that the dust cover body 211 is tightly adsorbed on the suction cup 3, thus fixing the workpiece. At this time, the dust cover body 211 is located directly below the grinding ring 210.

[0029] Working principle: The operator places the dust cover body 211 on the top outer side of the suction cup 3, and then starts the small vacuum pump 303. The vacuum pump draws air out of the suction cup 3 through the connecting pipe 301, so that the suction cup 3 forms a negative pressure environment, which makes the dust cover body 211 tightly adsorbed on the suction cup 3, thus completing the fixation of the workpiece. At this time, the dust cover body 211 is located directly below the grinding ring 210.

[0030] At this time, the grinding ring 210 is located at a high position inside the placement tube 201 and is not in contact with the dust cover body 211. The return spring 204 is in a naturally extended state. Then, the drive motor 209 is started, and the drive motor 209 drives the connecting rod 208 to rotate inside the placement tube 201. The connecting rod 208 drives the externally fixed cam 207 to rotate. When the protruding part of the cam 207 contacts the force block 206, the force block 206 is subjected to downward pressure, causing the hollow ring 203 to slide down along the groove 202 on the inner wall of the placement tube 201. At the same time, the return spring 204 is compressed. Meanwhile, the grinding ring 210 at the bottom of the locking bracket 205 moves along with the hollow ring 203. The 3 descends and covers the outer surface of the dust cover body 211. During the bonding process, the outer edge of the dust cover body 211 is polished to remove burrs. As the drive motor 209 rotates continuously, it drives the cam 207 to rotate continuously, so that the force block 206 is periodically subjected to pressure and released pressure. This causes the polishing ring 210 to move up and down in the slide groove 202, which fully polishes and removes burrs from the outer edge of the dust cover body 211. The debris generated during the polishing process enters the device through the bottom hole 305 for collection. It is then uniformly processed by the staff to prevent waste from accumulating in the processing area and affecting the processing effect and normal operation of the equipment.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
