Description

Technical Field

[0001] This invention belongs to the field of metal processing technology, specifically a burr scraping device for metal parts processing. Background Technology

[0002] During the metal parts processing, due to the inherent characteristics of forming processes such as cutting, stamping, casting, and forging, burrs, flash, sharp edges, and other excess material residues will inevitably be generated on the surface and edges of the workpiece. These burrs not only affect the assembly accuracy and appearance quality of the workpiece, but may also cause scratches, stress concentration, and other problems during subsequent use. In severe cases, they may even affect the safety and service life of the entire machine.

[0003] A utility model patent with publication number CN224543341U discloses a scraping device for cleaning burrs on a gear shift rocker arm. The operator holds and pushes the gear shift rocker arm to move it, and the scraper blade is in constant contact with the surface of the gear shift rocker arm to remove burrs. The removed burrs are located at the top of the receiving plate. The suction force generated by the exhaust fan will drive the small burrs through the feed port into the burr collection box. The inner inclined support frame set at the front of the exhaust fan and the polyester fiber filter cloth work together to collect the burrs. The burrs are attracted by the suction and adsorbed on the surface of the polyester fiber filter cloth, so as to prevent the burrs from affecting the normal operation of the device.

[0004] In actual use, the above technical solution requires operators to manually scrape the workpiece one by one to remove burrs, resulting in low work efficiency. At the same time, the scraping force and scraping angle depend on manual control based on experience. Excessive force can easily lead to overcutting or scratches on the workpiece surface, causing damage to the workpiece and forming quality defects, which in turn affects its assembly accuracy and usage stability. Insufficient force will result in incomplete deburring, and residual burrs may still cause stress concentration or safety hazards in subsequent use.

[0005] Therefore, the present invention provides a burr scraping device for metal part processing. Summary of the Invention

Simultaneously, through the inclined surface cooperation between the lifting frame, the limiting teeth, and the lifting block, the top plate is automatically locked during the correction and reset process to prevent the spring rebound from causing secondary displacement of the metal part. It automatically unlocks after complete reset, thereby achieving precise positioning and holding during the correction process. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] According to an embodiment of the present invention, a burr scraping device for metal part processing is provided.

[0024] Example 1: As Figures 1 to 2 As shown, an embodiment of the present invention provides a burr scraping device for metal part processing, including a processing table 1. A first cylinder 11 is installed at the top of the processing table 1. Guide holes 113 are provided on both sides of the top of the processing table 1. A first mounting frame 112 is slidably connected inside the guide holes 113. The output shaft end of the first cylinder 11 is fixedly connected to the first mounting frame 112. A pair of scraping blades 111 are installed on both sides of the first mounting frame 112. A placement frame 12 is provided at the top of the processing table 1. A second mounting frame 122 is fixed at the top of the placement frame 12. A third cylinder 123 is installed at one end of the second mounting frame 122. A fixing frame 124 is fixed at the output shaft end of the third cylinder 123. A metal part 2 can be clamped between the placement frame 12 and the fixing frame 124. A steering component is provided at the bottom of the placement frame 12 for driving the metal part 2 to rotate 90°. Correction components are provided on both sides of the placement frame 12.

[0025] like Figures 1 to 3As shown, the steering assembly includes a second cylinder 121 installed on the side of the processing table 1 near the first cylinder 11. The bottom end of the placement frame 12 is rotatably connected to a connecting block 125. The top end of the processing table 1 is provided with a sliding groove between the guide holes 113. The connecting block 125 can be slidably connected inside the sliding groove. The output shaft end of the second cylinder 121 is fixedly connected to the connecting block 125. A steering component is provided inside the connecting block 125.

[0026] like Figures 1 to 4 As shown, the steering component includes a gear shaft 126 rotatably connected inside the connecting block 125. Both ends of the gear shaft 126 are fixedly connected to the placement frame 12. A connecting gear 127 is rotatably connected inside the connecting block 125. The top end of the connecting gear 127 meshes with the gear shaft 126. A toothed plate 128 is slidably connected inside the connecting block 125. The top end of the toothed plate 128 meshes with the connecting gear 127. When one end of the toothed plate 128 is fully pushed into the interior of the connecting block 125, the placement frame 12 rotates 90°.

[0027] During the production of metal part 2, metal part 2 is cut from a larger metal plate into smaller strips. During the cutting process, burrs inevitably appear and need to be scraped off to keep the exterior of metal part 2 clean. In the initial state of this cleaning process, the third cylinder 123 is in a shortened state, and the fixing frame 124 is away from the placement frame 12. Then, metal part 2 is placed inside the placement frame 12. Subsequently, the correction assembly corrects the deviation of both sides of metal part 2. After correction, the third cylinder 123 is activated to push the fixing frame 124 towards metal part 2. The inner side is pressed tightly, which can fix the metal part 2 between the placement frame 12 and the fixing frame 124. Then, the first cylinder 11 is activated. In the initial state, the first cylinder 11 is in its longest extended state. The first cylinder 11 pulls the first mounting frame 112 to slide inside the guide hole 113. The first mounting frame 112 drives the scraper 111 to move. The blade of the scraper 111 will stick to both sides of the placement frame 12 during the movement. The placement frame 12 is consistent with the normal width of the metal part 2. Therefore, when there are burrs on both sides of the metal part 2, the burrs will be scraped off by the scraper 111. The shape of the metal part 2 is usually not a conventional flat plate. The scraper 111 can only clean burrs in the current direction. Therefore, the orientation of the metal part 2 needs to be adjusted. Before adjustment, the first cylinder 11 drives the scraper 111 to return to the initial position. The second cylinder 121 is initially in a shortened state. At this time, the second cylinder 121 pushes the connecting block 125 to slide inside the slide groove. When sliding, the connecting block 125 drives the placement bracket 12 and the metal part 2 to move in the direction of the scraper 111 until one end of the toothed plate 128 contacts the slide groove. When the slide is blocked by the inner wall of the slide, the toothed plate 128 can slide from one side of the connecting block 125 to the other side. While sliding, the toothed plate 128 drives the connecting gear 127 to rotate, and the connecting gear 127 drives the gear shaft 126 to rotate. At this time, the gear shaft 126 can drive the placement frame 12 to rotate 90° to the other side. At this time, the other side of the metal part 2 rotates to be close to the surface of the processing table 1. Then, the first cylinder 11 drives the scraper 111 to move to scrape the burrs on the other side of the metal part 2, thereby realizing automatic burr scraping of the metal part 2. Next, the second cylinder 121 pulls the connecting block 125 to reset, and pushes the toothed plate 128 in the opposite direction through the other side of the inner wall of the slide groove, so that the placement frame 12 can be driven to rotate 90° in the opposite direction to reset. The first cylinder 11 drives the scraper 111 to automatically reset, and at the same time the third cylinder 123 drives the fixing frame 124 away from the metal part 2, so that the metal part 2 can lose its limit. Then the processed metal part 2 can be removed.

[0028] Example 2: Figures 1 to 5 As shown, the correction assembly includes a pusher 132 that is slidably connected to both sides of the placement frame 12 via a support frame. A pusher plate 13 is fixed on one side of the pusher 132. A servo motor 134 is installed at the top inside the processing table 1. A drive component is provided at the other end of the pusher 132.

[0029] like Figures 1 to 5 As shown, the driving component includes a servo motor 134 installed at the top of the inside of the processing table 1. A gear is fixed to the top of the servo motor 134. A rack 133 is fixed to the end of the pusher 132 away from the push plate 13. The teeth of the two racks 133 are meshed with the gear of the servo motor 134.

[0030] like Figures 5 to 7 As shown, a plurality of top plates 131 are provided on one side of the push plate 13, and the thickness of the top plate 131 is less than the thickness of the metal part 2.

[0031] like Figures 5 to 7 As shown, a telescopic rod 1311 is fixed on one side of the top plate 131. The telescopic rod 1311 is slidably connected to the inside of the push plate 13. A first spring 1312 is sleeved on the outside of the telescopic rod 1311. One end of the first spring 1312 is fixedly connected to the telescopic rod 1311, and the other end of the first spring 1312 is fixedly connected to the push plate 13.

[0032] like Figures 5 to 7 As shown, a movable block 1313 is fixed to the other end of the telescopic rod 1311, a lifting frame 135 is provided at the bottom end of the push plate 13, a plurality of top blocks 1352 are fixed at the top end of the lifting frame 135, the top blocks 1352 are slidably connected to the bottom end of the push plate 13, a top frame 1351 is fixed to one side of the lifting frame 135, a guide block 136 is fixed to the top end of the processing table 1, and an inclined surface is provided on the side of the guide block 136 near the top frame 1351.

[0033] like Figures 5 to 8 As shown, the bottom of the movable block 1313 is provided with multiple telescopic cavities 1314, and the inside of the telescopic cavities 1314 is slidably connected to the lifting block 1315. The top of the top block 1352 is fixed with multiple limiting teeth 1353, and the inclined surfaces of the lifting block 1315 and the limiting teeth 1353 are opposite in direction.

[0034] like Figures 5 to 7 As shown, a second spring 1354 is fixed to the top of the lifting frame 135, and the top of the second spring 1354 is fixedly connected to the push plate 13.

[0035] Before the fixing frame 124 clamps the metal part 2, the position of the metal part 2 needs to be corrected. During the correction process, the servo motor 134 is started to drive the end gear to rotate. The gear drives the racks 133 on both sides to move. Since the racks 133 on both sides mesh with the gear in different directions, the gear drives the racks 133 on both sides to move in opposite directions. This allows the racks 133 to drive the pusher 132 to move closer to the placement frame 12. At this time, the pusher 132 pushes the push plate 13 to move towards the metal part 2. The push plates 13 on both sides can clamp the metal part 2 towards the center, so that the metal part 2 is in a position flush with the sides of the placement frame 12. However, since there are burrs on both sides of the metal part 2, the burrs will be placed between the push plate 13 and the metal part 2 during the correction process, which will cause the push plate 13 to be inaccurate in correcting the metal part 2. Therefore, multiple top plates 131 are set on one side of the push plate 13. The top plates 131 are flat. When the top plates 131 come into contact with the metal part 2, they will contact the middle position of the metal part 2. The burrs of the metal part 2 are usually located at the upper or lower end of the side. The top plates 131 will not come into contact with the burrs, which can better correct the metal part 2. However, if the burr appears in the middle of the metal part 2, the top plate 131 will be affected. Therefore, a first spring 1312 and a telescopic rod 1311 are provided. When one or more of the top plates 131 come into contact with the burr, the burr will push the top plate 131, and the top plate 131 will push the first spring 1312 to compress. The telescopic rod 1311 guides the movement direction of the top plate 131. The length of the burr in the middle is usually less than the length of the plane. Therefore, the pushed top plate 131 and the first spring 1312 will not affect the correction of other top plates 131. After the correction is completed, the top plate 131 needs to be separated from the metal part 2. During the separation process, the first spring 1312 will cause the current top plate 131 to rebound. At this time, the top plate 131 will push the burr and cause the metal part 2 to shift again. Therefore, a structure that can lock during the reset process is provided at the end of the telescopic rod 1311. During the movement of the push plate 13 towards the placement frame 12, the top frame 1351 will move towards the guide block 136. The inclined surface of the guide block 136 guides the top frame 1351, causing it to move upward and drive the lifting frame 135. Simultaneously, the guide block 136 maintains the height of the top frame 1351 and the lifting frame 135. At this time, the lifting frame 135 drives multiple top blocks 1352 and limiting teeth 1353 to move upward. Then, the top plate 131 contacts the metal part 2. The top plate 131 pushes the movable block 1313 through the telescopic rod 1311, moving inside the push plate 13. During the movement, the lifting block 1315 moves above the limiting teeth 1353. At this time, the limiting teeth 1353 will block the lifting block 1315, but because of the inclined surface of the limiting teeth 1353 and the lifting block 1315... The inclined plane of 15 will push the lifting block 1315 upward, causing it to retract into the telescopic cavity 1314. After passing the top of the limiting tooth 1353, the lifting block 1315 will fall back to its original height under the action of gravity. When the top plate 131 stops being pushed, the movable block 1313 stops moving. Then, the push plate 13 moves in the opposite direction to reset, separating the top plate 131 from the metal part 2. At this time, the vertical surface of the limiting tooth 1353 will lock the vertical surface of the lifting block 1315, thereby locking the movable block 1313 and causing it to return to its original position. During the positioning process, the top plate 131 remains stationary and will not be pushed by the elastic force of the first spring 1312 to cause the metal part 2 to shift. When the top frame 1351 is separated from the top of the guide block 136, the second spring 1354 pushes the lifting frame 135 to reset downwards. At this time, the lifting frame 135 drives the top block 1352 and the limiting tooth 1353 to move downwards. At this time, the lifting block 1315 loses its lock. Under the action of the first spring 1312, the top plate 131 can be automatically reset, thereby realizing the automatic locking and reset of the top plate 131, which makes it easier to correct deviation.
